The invention relates to telecommunications, electronics and computing. It is applicable for system management features with Autonomous power supply, for example, a motor vehicle.

In known devices of the control system with a large number of objects (SU 460530, 20.06.1975; SU 652527, 15.03.1979; SU 1295369, 07.03.1987; WO 97/19393, 29.05.1997) necessitates the implementation of a large number of control loops that connect these objects through the regulators, the result is a complex, extensive, time-varying system object relations with regulators and between regulators. A large number of physical links (e.g., wires or frequency ranges transmission) leads to considerable noise and sharp complication of physical implementation of the control system, and this, in turn, reduces the quality control. In addition, dramatically decreases the reliability of control systems, their adaptability to the specific object, to change functions as the object, and the system as a whole.

Also known device (EN 2138120, 20.09.1999; DE 19621384, 28.11.1996; DE 19838469, 02.03.2000; EN 2178952, 27.01.2002; EP 0754990, 22.01.1997), using for control of a large number of objects another principle of communication - so-called channel. Instead of an extensive network they use a limited number of communication channels with sequential p is the transfer of information. Implementation of the channel means of communication controllers, sensors and actuators object while maintaining the principle of an independent management objects makes use of high speed transmission of control information over the communication channel. This is due to the requirement to provide a small step to the temporary quantization information with the aim of preserving the quality of regulation. The increase in the number of objects and loops increase the loading of the channel clock and the service information, the maximum amount which is achieved with minimal dependencies processes connected to the channel devices. Thus the effective transmission rate control information at a fixed transfer rate falls. Ensuring the immunity of the communication channel also requires an increase in transmission speeds.

The closest analogue (prototype) of the claimed device is a control system of distributed processes (WO 03/019303, 06.03.2003). The system contains managed objects that are members of a specific system ("distributed object"); adapters (controllers) devices, each of which software controls the processes in one of the system objects; "master" - a device that provides control of the process of exchange of information between the adapters. The objects of connection is received by a channel of communication through the adapter.

Each adapter contains a communication interface (combines the functions of a transmitter and a receiver) and a stepper controller. The latter performs the following functions: scan the received information in accordance with the process number of the object, processing the information from the object, transfer it after processing, the control object in accordance with information received via a communication channel in accordance with the step of the regulatory process.

The master synchronizes the operation of the adapters, accumulating information about the status of processes on objects and distributing it according to the processes that leads to the simultaneous existence in the system of two non-synchronous data flows (the flow of information transmitted by the object, and the flow of information, grouped by processes).

The impossibility of complete synchronization of information flow in the prototype leads to the impossibility of establishing sustainable contours of the management processes, which includes more than one node, if the full cycle of currency comparable in time with the feedback loop that generates "noise control". In the prototype does not provide any protection from external interference. These features significantly reduce the quality of regulation that limits the scope of the system only environments with large constant time ("slow" sites - museums, cinemas, amusement p the RCTs, chemical processes and so on).

The technical result of the claimed invention is to improve the quality of management.

A device management system of objects containing connected with Autonomous power supply, power cord, adapters, connected between the power wire and the objects that make up the objects of the control loops and made programmable with the ability to synchronize the receipt of the information, in which the power wire at the same time serves to transmit information, and the adapters are made with consideration of interference. Adapter, connected between the power wire and the auxiliary power source is made, in addition, with the capability of synchronizing the transfer of information between other adapters in accordance with the considerations of interference and voltage regulation of power.

There are also adapter specified device containing the receiver, transmitter, scanner, operative memory (hereinafter RAM), the control block object, the synchronizer, the block I / o block converters. The control block object block I / o and block converters made programmable. The first input of the receiver is designed to connect to the power wire, a first output connected to the first input of the scanner, the second in the move - to the first clock input and a third output to the first input of the transmitter. The second input of the transmitter connected to the first output of the scanner, the third input to the first output of the synchronizer, and the output is intended for connection to the power wire. The second input of the scanner connected to the first output of RAM, and a third input to the second output of the synchronizer. The first input of the control block object connected to the fourth output of RAM, and the first output to the fourth input of RAM. The first input of the RAM connected to the first output block I / o, the second input to the third output of the synchronizer, the third input to the second output of the scanner, and the third output to the first input of the block I / o. The second input block I / o connected to the first output unit converters, and the second output to the first input unit converters. Unit converters has, in addition, the inputs and outputs for connection to the object. In the inventive adapter first output of the scanner is connected to the second input of the receiver, a second clock input connected to the fifth output of RAM, the third input to the second output of the control block object, a fourth input to the third output block I / o, and the fourth output to the second input of the control block object.

The technical result is achieved in the invention by implementing some of the factors. This is, firstly, the organization of continuous random access to system information for all control blocks objects with a minimum number of physical links. Secondly, it is a reduction of noise of the communication channel caused by random variation in time of the net delay for each of the component control information. The speed of transmission over the physical communication channel is not significantly increased, which is achieved through adaptive centralized synchronization exchange. Third, this reduction in each parcel share proprietary information (i.e. address, information about the length and priority parcels and the like), thereby increasing the share directly control information. And finally, fourth, ensuring high noise immunity at the expense of eliminating most of the noise from the transfer of information while minimizing the time spent on the implementation of this process.

The structure and functioning of the claimed invention is illustrated graphic materials, in which figure 1 presents a diagram of the device management system of objects, figure 2 - wiring adapters to the objects in figure 3 - circuit adapter device management system of objects figure 4 - schematic diagram of the operation of the device, figure 5 - block diagram of the procedure f is Mirovaya the transfer token skip cycles, contains interference, 6 is a timing chart of the currency, figure 7 - timing diagram types of the tokens.

The device management system of objects (scheme in figure 1) contains connected with Autonomous power supply 1 power cord 2, adapter 3, connected between the power wire and objects 4 and forming with the objects of the control loops. Power wire at the same time serves to transmit information. The adapters are made programmable with the ability to synchronize data reception and recording of the interference. The adapter 3', connected between the power wire and the auxiliary power source is made, in addition, with the capability of synchronizing the transfer of information between other adapters in accordance with the considerations of interference and voltage regulation of power.

Provides two options for connecting the adapter to the object (figure 2). When connecting to the integrated management system object adapter 3' at the junction with the object control system performs the functions of the simulator control signals control loop i and the partial function controls the control circuits i, l. When connecting the adapter directly to the sensors and the actuators of object adapters i and k functions as a regulator of object k at this junction and the partial function of the circuit regulators reg is the regulation i, l...i, k.

The adapter device management system of interest (the diagram in figure 3) contains: receiver 5, a transmitter 6, the scanner 7, RAM 8, the control block object 9, the synchronizer 10, block I / o 11 and unit converters 12. The control block object block I / o and block converters designed programmable.

The first input of the receiver 5 is connected to a power wire, a first output connected to the first input of the scanner, the second output to the first clock input and a third output to the first input of the transmitter. The second input of the transmitter 6 is connected to the first output of the scanner, the third input to the first output of the synchronizer, and the output is intended for connection to the power wire. The second input of the scanner 7 is connected to the first output of RAM, the third input to the second output of the synchronizer, and the first output to the second input of the receiver. The first input of the control block object 9 is connected to the fourth output of RAM, and the first output to the fourth input of RAM. The first input of the RAM 8 is connected to the first output block I / o, the second input to the third output of the synchronizer, the third input to the second output of the scanner, and the third output to the first input of the block I / o. The second input of the synchronizer 10 is connected to the fifth output of RAM, the third input to the second output of the control unit of the object is m, the fourth input to the third output block I / o, and the fourth output to the second input of the control block object. The second input block input / output 11 connected to the first output unit converters, and the second output to the first input unit converters. Unit converters 12 has, in addition, the inputs and outputs for connection to an object: the inputs are connected with the sensors, and the outputs from actuating mechanisms of the object.

Each of the adapters within a time slice τnn loop performs the following steps:

- process data object Xin;

- generates a vector of commands Minthe actuators object i;

- forms on the basis of Mindata partial regulators for other objects (k);

- generates a pointer interference of the actuator j-Njn;

- conveys the magnitude of the change data, if it is different from zero, and the pointer interference generated in the previous cycle (n-1).

To perform these actions in the adapter includes 5 receiver and transmitter 6, covered by a feedback circuit (hereinafter OS), which provides the coordination of the transmitter and the communication channel, as is done, for example, in US 4745391, 17.05.1988.

The receiver, in addition to the sequence data on the scanner 7, highlights from the incoming signal, the sync markers exchange process M and eredet their input synchronizer 10, which in turn gives control commands to the scanner. Scanner, taking the sequence data from the receiver and commands from synchronizer:

- forms input area of the interface window RAM, sorting data in accordance with input vectors of partial regulators X(n-1)ij;

- forms the area of the mask execution interface window RAM;

- displays on the transmitter sequence data corresponding to the output vector of partial regulators Y(n-1)0ijand the interference vector Ni(n-1)from the zone output interface window RAM.

The synchronizer reads from the zone synchronization interface window RAM adapter number, the indicator of availability of information, label interference, confirmed by the output signal from the block I / o is synchronized with the token received from the receiver, and outputs the command to the blanking transmission to the transmitter.

In parallel with this process, the synchronizer performs a procedure of forming the current index of the interference in response to a signal from the control unit by object about the place of their appearance.

The control block object performs procedures as a regulator of its object and partial regulators other objects, as specified in the zone mask the execution of the working window, and generates the output area working window RAM.

Block I / o procedures (the drive is s):

- output vector commands Minto the actuators of the object through the power converters from the zone buffer I / o working window RAM;

- input and preparation of data from sensors of the object, the driving unit converters and forming the data object Xinin the area of the input buffer of the working window RAM.

At the end of the exchange cycle synchronizer generates RAM command swap interface and the operating Windows of the RAM.

The flowchart of the procedure of forming the commands and data are shown in figure 4.

At the beginning of the cycle, the adapter processes the data DIjn(where j is the number of the object; n is the number of loop), coming from sensors connected to the adapter object.

According to the data obtained in the previous cycle X0inthe adapter generates the data control loops

Y0(n+1)=Pij*X0in(DIjn),

where Y0(n+1)- vector control;

i - the number of the control loop;

Pij- the transfer function matrix of the j-th element of the i-th control loop.

Pij=Wij(Z)*TSij(Tc)

where TSij(Tc) is the diagonal matrix of the form (1-e-ki*S*Tc)*e-ki*S*Tc/s;

ki- current ratio of the delay of the i components of the vector X0in.

According to the data obtained in the previous cycle X0inthe adapter fo the reports control inputs to the actuators of the object

S0i(n+1)=WSij*X0in(DIjn),

where WSijmatrix transfer functions of its host species, similar to Pij.

The adapter then provides control signals S0into the actuators of the object and generates a pointer interference Nj(n+1)according to the description of the object.

In parallel with the above steps, the adapter accepts X0inand passes Y0incombined with Nj(n+1).

The flowchart of the procedure of forming the transfer token skip cycles containing interference, shown in figure 5.

The control block object adapter i, forming the management team the Executive mechanism j, determines the time τ from the beginning of the cycle of exchange prior to its execution and places it in the interference zone of the map RAM adapter.

Formed in the current cycle n exchange of fragment Ninclutter map is transferred to the master in cycle n+1 exchange.

Simultaneously formed in a loop n management team the Executive mechanism of the object to the area of the output RAM, in cycle n+1 is transferred to the buffer area of the I / o RAM and executed by the block I / o in cycle n+2 and the quantum Ni(n+2).

In parallel, the wizard, using the entire set of Ni(n+1)...Ni(n+1)...that calculates the moments of the interference and produces the measure of exchange that are earlier than these points, the marker skip beat is the beat of N i(n+2)providing a pass interference interval.

The transmission and reception are carried out on a power wire as follows.

Timing chart of currency is shown in Fig.6, the timing diagram of types of markers - 7.

Adapter connected to the power unit (hereinafter referred to as the master generates the start marker transmission M1 and synchronizes the transfer of each bit of the token MB.

Another adapter or issues a token transfer M2, passes Yoncombined with Nj(n+1)and the last bit marker M3, or issues a token passes quantum M4, which is the sum of M2 and M3. In the absence of the marker adapter wizard generates the token of the last bit M3.

The adapter number k takes the data and stores them in positions 1, 2...k-1, k+1,... until the next marker, M1.

The adapter number k in obtaining k-1 marker M3 transmits the data as shown above.

After receiving the token M4, all adapters pause for 2 stroke transmission.

In comparison with the known analogues, used in the automotive industry, the invention provides a noise level below 40 dB, the transmission rate control information above 15 times.
