The present invention relates to a system for monitoring and controlling one or more consumers of electric power, in particular household appliances, where such consumers of electrical power to exchange information and/or commands are connected with the first communication network via the interface means, where the transmitting-receiving means, connected to the specified first communication network is provided for establishing a communication channel with the second remote network and/or remote target device.

As you know, home automation, i.e. the use of electronic technologies in everyday conditions, with the objective of minimizing the management costs of the various consumers of electric power and new features of comfort, is becoming more and more real.

This is essentially due to

the increasing proliferation of consumer electronic equipment, such as VCRs, systems category HI-FI, satellite receiving systems, security systems and burglar alarm systems, personal computers, mobile phones, and so forth;

recent significant developments in the field of control systems, household appliances, based on the use of microcontrollers and new sensors, is the quiet capable of dialogue with the external apparatus;

the gradual establishment of standard communication channels, i.e. sets of rules limiting procedure of exchange of information from a variety of household appliances with the physical means through which such information is provided.

With reference to the last point seems especially become important means of communication are themselves normal household conditions, i.e. the so-called line of the power supply, which itself is a main power supply line to which information can be transmitted in the format of amplitude or frequency modulated by small signals. The use of such funds actually provides the ability to connect appliances to the trunk power supply line without the need for any new or special systems wiring.

As a result, new opportunities, based on the use of a power supply line, arose in connection with issues related to the rationalization of energy consumption in household conditions and to more efficient processing of information related to household consumers of electric power.

Also known remote control systems for domestic consumers of electric power, which use communication tools to ensure the Oia relation to special household appliance or household main power supply line to control the operation of one or more household appliances.

In the document TTOA, issued in the name of the present applicant, describes a system for monitoring and remote maintenance of household electrical appliances used in domestic conditions, which contains a device for monitoring, able to collect (through a local network connected to the specified consumers of electric power) functional, diagnostic and statistical information generated by these consumers of electric power and transmitted these consumers of electric power to the specified local network, and store it in the appropriate memory. Such a device for monitoring includes appropriate means, in particular, the modem global system for mobile communications, used for receiving and monitoring information received from household appliances, and transmission of such information may take place at the local level, i.e. to the user on the remote level inside the living conditions of operation, for example, to a personal computer, is actually available in these domestic conditions, with an adequate interface for the connection with the specified local network; finally, on a remote level out of home conditions, t is there special technical maintenance and repair.

In figure 1 the example illustrates a system for monitoring and remote maintenance of household appliances, which is a set of consumers of electrical power, consisting of household appliances such as washing machines, LB, electric cooker FO, refrigerator FG machine and dishwasher LS. This set of consumers U of electrical power is connected to the local network RE "line of supply", which has the telephone node NT, corresponding to the above-mentioned device for monitoring and control, and to provide a transmit-receive command and control through the external system.

Appliances FO, LS, FG, LB will also be indicated in the description below, as they are equipped with electronic control devices, capable of performing complex functions as electrical appliances or as intelligent consumers of electric power.

This is a known communication system enables the exchange of information between the various interface modules, indicated by the letter N, through the power cable, that is, without requiring additional wiring in domestic conditions.

The interface module N forms a "communications hub"through which each of the connecting device is Istv able to exchange information with an external apparatus through a power supply line. Therefore, each communication node has a corresponding front-end tool for network communication RE; in addition, it contains the control logic used to control communication protocols with channel (in other words, the rules governing the exchange of information with other nodes in the network) and the exchange of information with the associated device.

Technology related to network communication and related protocols known (reference is made, for example, on the common system of channels, such as LonWorks, CEBus, EHS, EIB...) and, therefore, not be further described in this application.

The telephone node NT contains a modem, not shown in figure 1, through which the local network'RE able to communicate with the external network IN, for example the Internet, or directly through the protocols designed for the dissemination of information materials on the Internet to receive or send information of a local network of RE and consumers U electric power connected with it.

As shown in figure 1, the telephone node NT is also made with the ability to communicate with the mobile telephone TC.

In such a system, disadvantages arise due to the presence of a special device control corresponding to the telephone node NT, shown in figure 1, which has an interface between the local network and means of communication, and the latter may be stationary or mobile phone. Such a device for monitoring and management is necessary to ensure the collection of all information and transfer it to the outside or to a personal computer, so that you can communicate with household appliances associated with the specified device for monitoring in special host on the local network.

If an available local network of supply lines through which electrical appliances are able to communicate in the local network there is a need in the new interface module, to enable communication with external devices, i.e. the new node, which will be specially connected device for monitoring and control, hence the need to increase the cost of the system. In addition, such a device for monitoring must physically be placed in household conditions, which is associated with an increase in the overall size and difficulty in choosing the proper location. Because such a device for monitoring and control due to the availability of the local network appliances, there is an additional disadvantage, if the consumer has a reduced set of household appliances or even just one household appliance, so topochemically be difficult to understand the benefits of installing such a device for the implementation of the current control.

In the patent EP-A-0391316 described electronic control unit, washing machines, dryers for linen and similar electrical appliances containing "main" microprocessor that is designed to store and manage the subsequent stages of each program of washing and/or drying of any model washing machines or clothes dryers manufactured on an industrial basis, and three auxiliary microprocessor. The control unit may further comprise separate interfaces that can be connected to the specified main microprocessor, and performed, respectively, with the ability to ensure the functioning of each selected program to encourage the implementation of work programs and control programs with the help of a microprocessor and to ensure that each work program any machine that is subjected to current control in a Central location, remote from the respective machine.

In the patent EP-A-0620631 described a control system for household electrical loads, containing the Central unit, which actuates many electrical coded signals, ensuring that they work in a programmed sequence. Each appliance contains a CPU, activating the Central unit signals coming from the a, which indicates electrical power required to perform the following working CPU, activating the Central unit request signals that indicate the electrical power required to perform the following working phase of the selected program. The Central unit responds to pings generation permissive signals to the electrical devices, the activation of which is currently in a period of competition relevant the following working phases requires total consumption of electric power, not exceeding the maximum. Appliances and the Central unit are connected through a radio transmitter and receiver in a common housing.

The present invention is to eliminate the above disadvantages and provide systems for monitoring and managing the set of consumers of electric power with higher efficiency and higher performance.

In this context, the main objective of the present invention is the provision of a receiving system for monitoring and managing the set of consumers of electric power that requires no additional new nodes to enable consumers of electrical power connect the I to obtain a connection to the local network from remote stations.

Another objective of the present invention is the provision of systems for monitoring and managing the set of consumers of electric power, which does not cause any difficulties associated with placing in household conditions.

Another objective of the present invention is the provision of systems for monitoring and managing the set of consumers of electric power, which ensures the availability of long-distance communication in the case of the minimum set of consumers of electric power.

To solve these problems, this proposed system for monitoring and controlling one or more consumers of electric power, in particular household appliances, in which these consumers (U) of electrical power is connected to the first network (RE) connection through an adequate front-end tools (N) (in particular, the communication node or interface module) to exchange information and/or commands, which provides a transmission-reception means (MS) (in particular, the telephone node)connected to the specified first network (RE) connection to establish a communication channel with the second remote network (IN) and/or remote terminal unit (CU).

When said transmitting-receiving means (is) part of the structural element (T) one of these consumers (LB) electrical power and share one of the interface means (N), associated with the specified user (LB) electrical power.

Various options and benefits of the proposed system are illustrated by the following graphics:

figure 1 - schematic diagram of the system for monitoring and managing the set of consumers of electric power in accordance with the prior art;

figure 3 - schematic diagram of control system for monitoring and managing the set of consumers of electric power, illustrated in figure 2.

Figure 2 illustrates a system for monitoring and managing the set of consumers of electric power corresponding to the present invention. This system reproduces the common elements corresponding to the system illustrated in figure 1, but in this drawing, the washing machine LB separated from the set of consumers U of electrical power and is connected to the local network through RE interface module N that is contained in the telephone node MC.

The telephone node MC, more well illustrated in figure 3, contains the modem MG mobile phone operating in the standard global system for mobile communications, and the communication node N that serves as an interface to the local network RE. Thus, the telephone node MC will perform the functions of the phone the bonds is NT, shown in figure 1, for consumers U electrical power working quite the same way. However, such a telephone node MC is associated with a special user U of electrical power (in this case - with a washing machine LB) and works as if it was an interface module N between the consumption of electrical power and LAN RE.

Thus, it can be noted that in this case no longer required firewall interface, i.e. the element of communication with the external network IN, while he himself is rather a household appliance, in this special case, a washing machine LB, which acts physically as a gateway into force of modems associated with it by connecting to the telephone node MC.

The telephone node MC, equipped with a modem MG, which is known in itself, capable of managing digital data and used for remote transmission of information likely the center of the repair and preventive maintenance of various household consumers of electric power.

Abbreviation TC specified external mobile phone global system for mobile telephony, which is capable of providing digital connection to the telephone node, in particular through SMS alphanumeric messages, the cat is that more simple for the consumers.

The telephone node MC, as shown in figure 3, is equipped with adequate means to

periodic fee on the electric network RE functional, diagnostic and statistical information generated by consumers FO, LS, FG and the LB device, identifying for each of them corresponding to the consumer of electric power, from which it comes,

storing said information in the respective funds permanent memory,

availability of specified information later from the outside via the telephone line in accordance with the relevant procedures.

Figure 3 illustrates the element of the washing machine LB together with the telephone node MC.

The telephone node MC is installed in the upper panel T washing machine LB. The specified upper panel T, the so-called "top", is removable, or in other words, the telephone node MC can be mounted in a washing machine LB optional, pre-installed to work on the main line RE power, i.e. pre-set associated with an interface module N, as well as with electric hob FO or dishwasher LS and the washing machine LB, as shown in figure 1.

For this purpose above the top panel T contains the telephone node MC, which in turn contains

m is the module M1 of the display, equipped with a dedicated microcontroller MC, capable of driving a fluorescent display D, which visually reproduce alphanumeric messages and to communicate with an electronic system To control a washing machine on asynchronous line L serial data;

module M2 modem that contains the module MG mobile phone with the appropriate antenna and interface module N, suitable for connection to the power grid, such as a local area network'RE also contains the microcontroller MC2 adequate power, which properly controls the modem MG mobile phone and an interface module having a connection at the same time with the module M1 display on asynchronous line L serial data transmission,

electronic programmable means MNVT permanent memory for storing data received from the main power supply line or from the outside, which is especially suitable for getting together with appropriate software, for example, contained in the memory to store programs microcontroller MC2, to obtain the updated display information contained in the memory management tools "smart" appliances.

As the module M2 modem and module M1 display contained in the upper panel the T washing machine LB, engage in dialogue with the electronic system To control a washing machine LB through WRAP-Protocol over asynchronous lines L serial data transmission, which is provided for communication with the interface module N washing machine LB.

Thus, the electronic system To control a washing machine LB will control module M2 modem and module M1 display contained in the upper panel of T is exactly the same as the standard communication node, whereas, on the contrary, the module M2 modem and module M1 display contained in the top panel T will use the same procedures communication interface module N to the electronic system With management, ensuring the correct emulation.

This means that the telephone node MC that emulates the interface module N, can be associated with any other household appliance, a pre-installed for LAN connection RE through the specified interface module n

The principle of the communication port or firewall interface associated with a washing machine LB, can also clearly be duplicated by any other consumer electric power, pre-installed for network communication RE.

Electronic control system includes a microcontroller MC with his own and permanent memory MNVC.

The program of the microcontroller MC WRAP contains-the Protocol pack is alausi the operation of the appliance, in this particular case - a washing machine LB. Through this Protocol, the external electronic device, such as a mobile phone vehicle, able to communicate by asynchronous line L serial data transmission, for example, via the interface module N, establishes communication with the network, will be able to perform at any time, without negative impact on the correct operation of the appliance, the following functions:

reading any area of RAM of the microcontroller MC,

entry into any area of the random access memory of the microcontroller MC,

reading any area of permanent memory MNVC electronic control system,

entry into any area of permanent memory MNVC electronic control system,

overall management of household appliance, in this particular case - a washing machine LB, which is peripheral or auxiliary element above the external electronic device (master or controller), for example a mobile phone vehicle.

The above five procedures to establish communication with an external apparatus, which forms the basis of the WRAP Protocol, allow the household appliance to implement its ability to connect to the local network RE and access to the Internet through through the creation of any firewall interface able to manage the TCP/IP Protocol.

It should be noted that the transmission system of a power supply line that belongs to the network RE, being able to reach speeds of 4800 bits/sec, has a much lower rate (usually less than 1200 bits/sec) due to interference in the communication line.

In contrast, with reference to the data transmission line of a mobile phone or regular phone line, can be obtained from a higher speed to a normal line (up to 56000 bit/s with an analog system and over 100000 bits/sec digital system), whereas for mobile communication, her work is currently performed with a speed of 9600 bit/sec, but it should be expected that this rate will be increased ten-fold when using the GPRS system.

Thus, to eliminate such differences speed information of the telephone node MC is able to collect and store generated "smart" household appliances FO, LS, LB, FG, as described earlier.

The control system of each "smart" household appliance actually programmed in accordance with known technology to record at least the diagnostic and statistical information at regular intervals of time in permanent memory means and then for their timely updates.

In addition, the system control each b is a Hilbert electrical device may generate and transmit to the telephone node MC functional information of a different nature, for example, related to the work programme or cycle activated by the consumer to the operating state or phase of the program, to commands or options selected by the user, to synchronize associated with the activations of individual electrical loads, likely to anomalous behavior of some components, and so forth.

Equally, the microprocessor MC2 telephone node MC is programmed to query at regular intervals of time (e.g. every 10 minutes or through another interval of time, in fact programmable through adequate external tool that can be associated with the same communication system power supply line) is always on the line, consisting of the main line RE supply such information that may become available from time to time, which is generated by the system To control each intelligent appliance; such information is collected in the appropriate media MNVT permanent memory, accessible to the telephone node MC. Thus, the database associated with the means MNVT permanent memory of the telephone node MC is continually updated and forms an image of the content in the media MNVT permanent memory belonging to each "smart" household appliance.

The contents of the decree which authorized "database" can be transmitted at regular intervals of time the telephone node MC Center repair and preventive maintenance for the above purposes. In fact, the telephone node MC can be programmed to transmit at regular intervals of time (for example, every 24 hours, or through another interval of time, in fact programmable via a suitable external means, which may be associated with the communication system of supply lines) external repair and preventive maintenance, requesting "database"containing information made available by the network RE power due to various "intelligent" household appliances.

The specified database is stored in permanent memory means of the telephone node MC, can have access directly from the outside through to the telephone node MC. Due to this possibility of interaction with the mobile telephone TC availability of these funds MNVT permanent memory of the telephone node MC, which act as a buffer memory or a buffer function between the external communication network, i.e. a network IN the Internet or mobile phone network, where the mobile phone vehicle typically operates at higher speeds, and network'RE running at a lower speed, increases the speed of data transfer.

Thus, anyone with access from the outside, can see the status of household appliances and consumer of electrical power, connect the data network'RE at speed, permitted external network, where accessed.

This is particularly important, for example, in the case of a large service Center, providing a large number of daily inspections and scan a large number of local networks RE, because of all the time saved waiting in will result in significant savings in total time and the opportunity to make practice maintenance.

The following is an example of a possible communication Protocol between the mobile telephone TC and LAN RE, that is, household electrical appliances connected to it.

The communication Protocol between the mobile telephone TC and "intelligent" household appliances such as electric stove FO modem MG global system for mobile communications, based on the following three types of commands:

remote control commands,

remote current control state,

remote triggering events.

The ability to limit the likely additional technical requirements related to the items of the consumers of electric power are provided for all three types of commands.

Table 1 shows the list of appliances connected to the network RE, illustrated in figure 1, with examples of codes assigned to these appliances.

The above list is only a list with the m electric devices, illustrated in figure 1, but may also be implemented TV, intended as a means through which alphanumeric messages on a mobile phone, a global system for mobile communications, can be adequately visually reproduced, shared or connecting the device to the Internet. Typically, the codes can also be assigned

other household appliances, such as dryers, microwave ovens, equipment for heat treatment;

household systems, such as air conditioners, heaters, security systems, alarm systems, lighting systems, fire extinguishing systems.

In that case, if the domestic us what the conditions of operation there is more than one appliance per prescription, for example, two washing machines for their discernment will be introduced a third character (specified in table 1 by the letter x), which is a digital character.

Can be given the following coding example:

LB0: home washing machine,

LB1: dishwasher,

OV0: electric stove.

The following are the possible commands from C1 to C11 remote controls for household consumers of electrical power connected to the network RE.

A list containing the remote-controlled domestic consumers of electric power, given as a non-limiting example, and these commands are known in themselves, except for commands C11.

Each team is chosen from the menu available on the mobile phone vehicle, which automatically translates into a corresponding encoded sequence of symbols for transmission to the modem MG mobile telephone node MC.

May provide the following remote control commands:

START (C1) Immediate start of the operating cycle (washing, cooking and so on) household appliance and its normal execution.

STOP (C2) Immediately end the shutdown execution cycle of the household appliance.

PAUSE (C3) Immediate pause in the work of the household appliance.

PAUSE END PHASE (C4) Pause at the end of the current phase of work, the working is on a loop.

DELAY (a, b, C) (C5) Delayed start cycle or team at the end of the household appliance.

RESET (C6) Cancellation all the installation information of the operating cycle of the appliance (program data+delay+...). The command will cause the unloaded condition of the reserve of the appliance (irrespective of the previous state).

PROGRAM DATA (C7) M1 (manufacturer ID)+relevant information relating to the operating cycle of the appliance. This command is the most important element differences between different manufacturers of household appliances.

START an IF... Condition=true (C8) start the execution of the loop when the condition expressed by the corresponding parameter (or set of parameters).

SELFTEST (C9) Request immediate execution of self-test. To execute this command, the appliance must be unloaded state reserve.

STATUS: Request the current operating status of the system.

CONFIG: returning the entire set of system configuration settings.

SEND A MESSAGE (TEXT...) (C11) to send an alphanumeric message for continuous visual reproduction (until and unless the appropriate local feedback to the user) in the respective display home is exploitatie, for example on TV, a special display, and so on).

The last two commands (C10 and C11) are different from the other commands in the sense that they relate to the entire system.

In particular, it provides an output command signal C10 GET CONFIG system configuration (number and type of available appliances, possible alarm systems, heating, lighting and so on), which may allow remote control. This information is used to configure themselves mobile phone menu global system for mobile communications, which sent this command.

In the specific case of team C SEND A MESSAGE (TEXT...) this is especially important, because the message appears on the display of any household appliance, adequately prepared beforehand for this purpose, that is either equipped with a display, or the display D of the telephone node MC. System in the mobile phone vehicle to control input symbols configured in accordance with this team C11 to receive alphanumeric characters in free format and send the message to the telephone node MC by pressing the data.

Information relating to the operating state of consumers U electric power, grid-connected RE, can also be taken on a mobile phone vehicle. For example, such information may be:

OFF (S1) Domestic e is ectropion not connected to the main power supply.

STAND BY (S2) Household appliance, connected to the main power supply ON, waiting for data programming, data pertaining to its programming related to its duty cycle and probable execution command.

PROGRAMMED (S3) Household appliance already received data programming for its cycle and is ready for the start command to execute the loop.

PROGRAMMED WAITING TO CTART (S4) Household appliance has received the START command IF, pending the appropriate conditions (delay, electric power, speed,...) and ready to perform the likely launch command for immediate execution cycle (START).

RUNNING (S5) Household appliance performs its duty cycle.

CYCLE FINISHED (S6) Household appliance has completed its operating cycle and is now in the UNLOADED condition of the RESERVE.

FAILURE (S7) the Execution of the business cycle was finally stopped due to catastrophic failure. If the appliance is equipped with a modern system of self-diagnosis, the type of failure will be described in detail.

PAUSE (S8) cycle of the household appliance is in a state of temporary pause, waiting for the command to continue execution of the loop.

CYCLE INTERRUPTED (S9) Household appliance finally forced to break its cycle and is in the UNLOADED condition of the RESERVE.

RUNNING GOING TO PAUSE (S10) Household electric is Pribor took command PAUSE END PHASE and waits for the end of the working cycle and takes PAUSED.

SELFTEST (S11) Household appliance performs a self-test.

Query the state of the entire system of control for a set of consumers of electric power shall be implemented by command GET STATUS C10, as follows from the data given above.

The feedback control system of the set of consumers of electrical power comprises an SMS message that contains encoded information about the state of the entire system for the visual display of the mobile telephone TC after adequate decoding.

Codes associated with individual consumers U of electrical power, are listed in table 1; the codes associated with the individual state, are in parentheses (S1...S11).

At least four possible cases regarding consumer U electric power or automated home system (for example, alarms and/or security) can be processlibrary network RE through the telephone node MC:

Notices E1: Information to the consumer about the normal operation of the household appliance, for example, "washing is finished!", "Cooking is finished!"

Warning E2: Information may not pose danger to people (neither for people nor for the environment), which is made with reference to the household appliance, for example, a refrigerator Door is left open is the fourth in the last five minutes."

Alarm E3: Information about serious problems (which can cause serious harm to the consumer and/or the environment)related to household appliance, or, in General, to household production environment, for example, "the temperature of the freezer has reached dangerous levels for protection of food products", "Signal about a gas leak or water", "Signal alarm".

Failures E4: Information (optional deactivation by default) about possible problems strictly related to the operation of the appliance, which does not cause security problems, but will affect the performance of the operating cycle of the appliance, for example, "Washing machine does not take water!", "The failure of the pump of the dishwasher!", "Sensor failure temperature freezer!".

If such a case occurs, the call is sent to one or more mobile phones TC global system for mobile communications, only if this case is of type (case E1, E2, E3, E4), pre-authorized by the consumer for remote control, for example, via mobile phone vehicle or the appropriate local funds. Information is sent only to the mobile phones of the vehicle.

Thus, the menu of the mobile phone vehicle global system for mobile communications should provide the possibility of resolution of the Neu-unauthorized transmission of messages generated on any cases (accidents)associated with the control system by a set of consumers of electric power.

The message being transmitted to the telephone node MC is out of the normal sequence of alphanumeric characters (standard text message), expressing informative content associated with the incident case. As a result, this message is completely disposes of the control system by a set of consumers of electric power.

Finally, it is also possible to transfer the settings, limiting procedure of exchange of information between consumers of electric power and mobile phone vehicle, which guarantee a remote control system and pre-assigned to the telephone node MC.

The number of installation parameters depends on the complexity of the system consumers of electric power and complexity of the dialogue with the mobile phone vehicle, remotely connected with it.

From the above descriptions become obvious features and advantages of the present invention.

Clear are the advantages of the system for monitoring and managing the set of consumers of electric power.

System for monitoring and managing the set of consumers of electric power, sootvetstvuyshee the present invention, described by a characteristic example, mainly provides the ability to remove one of the nodes in the network having a mobile phone Internet connection in one of the electrical household appliance, particularly a washing machine.

System for monitoring and managing the set of consumers of electric power corresponding to the present invention, particularly preferred, if it can be put in the top panel of the washing machine. In fact, this introduction in the upper panel is optional, so the user can first buy a washing machine that only pre-installed to communicate with the supply and use of locally available options, for example, control the consumption of electric power. The ability to communicate through the connection with the mobile phone, such as running on a mobile phone, can be entered in the local network later, just the introduction at the top panel of the machine.

It is also very beneficial to the consumer, presented in a convenient introduction communication with the external apparatus in the case of the minimum set of household appliances, i.e. if there is only a washing machine, instead of waiting for a more appropriate set of appliances for communication with external equipment.

The seminar is yserowany skilled in this technical field will be many obvious changes, which can be made in the system for monitoring and managing the set of consumers of electric power described in this application for a typical example.
