The invention relates to means for transmitting signals, in particular to a stand-alone device for the transmission of digital signals and systems remote control (RC) based on them.

The invention can be used to create Autonomous unmanned re the s sensors in industrial automation, systems for remote control of household and industrial appliances.

Known Autonomous transmitter of coded radio signals for security systems, containing piezoelectric element, providing the generation of electric charges by mechanical action on it, the unit for generating and transmitting radio signals in the air and the power circuit of the specified block from the piezoelectric element (see U.S. patent 5572190, op. 05.11.96).

A disadvantage of the known transmitter is that a relatively small electrical charge produced by the piezoelectric element by mechanical action on it, without actually changing flows on the capacity of the low-pass filter, which serves as a buffer storage charges for supply of the following block creation and transmission of coded radio signals. Low voltage output low-pass filter (5-12), suitable to supply the specified block transmission of signals generated due to the significant voltage drop across the active component of the filter, which, in turn, reduces delivered at the output of the circuit capacity. The threshold element and a silicon rectifier in the scheme to perform the role of a kind of energy Converter of lactosamine, without leading to an increase of the total charge in the source current pulse. The imperfection of silicon rectifier, used in the scheme, namely the low breakdown voltage of the diodes (several hundred volts) and current leakage back biased diodes reduce the permissible value of voltage at its input and limit, thereby, the possibility of a scheme sufficiently large current pulses. As a result, the charge accumulated in the capacitance low-pass filter will be relatively small, which reduces the efficiency of the circuit of electrical power known transmitter of radio signals in General.

Also known for a variety of devices and remote control of electrical devices, including the system control illumination (see U.S. patent 3971028, op. 20.07.76), the system control ceiling fan (see U.S. patent 4371814, op. 01.02.83), television and audioprojektai (see U.S. patent 3928760, op. 23.12.75), transmitter for remote control locking of the vehicle (see U.S. patent 5592169, op. 07.01.97).

In particular, the system remote control car lock described in U.S. patent 5592169, contains a stand-alone transmitter coded control signals, the receiver and the control unit lock. The receiver system remote control receives power from the same electrical network and Upravleniye - battery or a battery.

The need for periodic acquisition cost of the batteries, charge the batteries and timely service stand-alone transmitter, as well as economic and environmental problems associated with disposal of used batteries, are the main disadvantages of such systems of control and restrict their wide dissemination.

Known attempts to create systems of control power to the transmitter from the piezoelectric elements, as for example, in the device for managing electronic toy (see U.S. patent 4612472, op. 16.09.86). In this device, however, the transmitted signal is not digitally encoding information necessary to control various functions of the Executive mechanism of the controlled object, and the charge from piezoelement used by the transmitting device directly without pre-treatment, i.e. extremely effective.

The use of piezoelectric elements or other generators of charge to create a remote control for household or industrial appliances, the authors do not know.

The objective of the invention is the creation of a stand-alone transmitter digital signals that do not require periodic replacement or recharging of the power supply, with an effective scheme pitama collect information and alert system with the possibility of long-term embedding of transmitters signal DN in non-maintenance of constructions and structures, like a traditional wall switch.

This technical result is achieved by the fact that in standalone transmitter digital signals containing a source of electrical power, comprising a generator of electric charges with the means of activation, the energy Converter of electric charges, whose input is connected to the generator output electric charges, and block the formation and transmission of the digital signal, an input connected to the output of the energy Converter of electrical signals, in accordance with the invention, the energy Converter of electric charges made in the form of a step-down transformer, the primary winding of which is the input of said Converter, and its secondary winding through a rectifier connected with the drive of the electric charges, which is the output of the energy Converter of electric charges. The secondary winding may consist of two windings having a common output connected to one output of the drive electric charges, and two other terminal of the secondary winding through a full-wave rectifier connected to another output of the drive electric charges. This embodiment of the winding boehlke allows you to customize the number of coils in each leg of the secondary winding and, more importantly, to avoid double of the voltage drop across the rectifier diodes. This embodiment of the Converter is particularly effective when the generator charge produces a short high-energy pulses.

In one embodiment, the implementation of Autonomous transmitter digital signals containing a source of electrical power, comprising a generator of electric charges with the means of activation, the energy Converter of electric charges, whose input is connected to the generator output electric charges, the drive electric charges connected with the output of the energy Converter of electric charges, and block the formation and transmission of the digital signal, an input connected to the output of said drive electric charges, the energy Converter of electric charges can be made in the form of semiconductor Converter, the input region which is the entrance of the energy Converter of electric charges and formed semiconductor structure, designed for accumulation of charges from the generator of electric charges and the formation of avalanche breakdown when exceeding the threshold voltage oplasty separation and accumulation of secondary charges, the resulting avalanche breakdown, and is connected through a rectifier to drive the electric charges.

The above technical result is also achieved by the fact that in standalone transmitter digital signals containing a source of electrical power, comprising a generator of electric charges with the means of activation, the energy Converter of electric charges, whose input is connected to the generator output electric charges, and block the formation and transmission of the digital signal, an input connected to the output of the energy Converter of electric charges, in accordance with the invention, the energy Converter of electric charges made in the form of capacitor banks equipped with a switching device designed to switch capacitors in serial connection, required for accumulation of charges from the generator of electric charges, on subsequent parallel connection, which allows to sum the charges accumulated in each capacitor, with a simultaneous lowering of the potential of these charges at the output of the Converter.

Generator electric charges may be made in the form of a piezoelectric element, triboletti. Prigov high electric potential, as for example, a radioactive source of charged particles, which may be in the form of a capacitor in which one plate contains radioactive material emitting the charged-particles, and the other plate serves as a collector.

The last two types of generators of electric charges produce the charge relatively slowly, so the number of converters described above, it is desirable to Supplement the shaper short pulses connected between the generator output electric charges and the inverter input power of electric charges made like a gas discharge tube or semiconductor threshold element, such as a thyristor.

Block the formation and transmission of the digital signal in standalone transmitter in accordance with the invention can be made with the possibility of wireless transmission, optical signal or an acoustic signal. In some transmission systems, digital codes for long distance optical option stand-alone transmitter is very effective when using laser emitter signals.

The present invention allows to create standalone beacon in which the quality of the electric generator is activated such devices in space, in marine navigation systems with virtually no maintenance.

In addition, this technical result is achieved by the fact that the remote control system containing a transmitter, designed for the creation and transmission of remote control signals, a receiver associated with said transmitter communication channel and is designed to detect signals from the remote control and the device processing and management, designed to highlight the digital code of the remote control signal and generate control commands, at least one electrical device in accordance with the selected digital information, in accordance with the invention, the transmitter signals DN performed as a stand-alone transmitter digital signals on any of the options described above.

This channel of communication in this system, the remote control can be formed wire galvanic connection, a wired connection with different types of galvanic isolation, or made in the form of a radio channel, an optical channel or acoustic channel.

In this control system as managed electrical appliances can be used for lighting, appliances, provided the honours, the devices of the notification, alarm and, in particular, the computer that processes and stores information received from the Autonomous transmitters digital signals.

An important feature of this control system is that the mentioned transmitter signal control can be performed with the possibility of embedding in the walls of buildings and other non-maintenance of engineering structures, because such generators charge as piezoelectric elements, triboletti, radioactive sources of charged particles does not require maintenance such periodic replacement or recharging of batteries.

The principal possibility to achieve the above result can be explained on the basis of compliance with the energy conservation law for the relevant invention conversion, which is perfect and looks like qUin=QUout, where q and Uin respectively the charge and the potential at the input of the Converter, and Q and Uout respectively the charge and the potential at the inverter output. Based on this condition we can estimate that for increasing (multiplying) the number of charges at the output of the Converter, i.e., conditions for Q>q, it is necessary that the potential at the input of preoper potential charges produced by the generator charges, such as piezoelectric elements or triboletti, is inversely proportional own or load capacity and can reach several thousand volts, while the potential required to power the electronic circuits of the transmitter is only a few units of volts. The efficiency of the process of multiplying the number of charges is determined by the efficiency of the Converter in relation to the process of transferring electrical energy source charge from the input of the Converter on the output.

The invention is illustrated by examples of its implementation, illustrated by drawings, which presents the following:

Fig.2B - Converter circuit, which is made on the basis of a step-down transformer with a threshold element at the entrance,

Fig.3 diagram of the Converter based on a semiconductor structure,

Fig.4 - Converter circuit based on a battery of capacitors,

Fig.5 is a block diagram of a system for remote control of electrical devices.

As showing the s, and the output of the inverter 2 is connected to the input of the shaping unit and the transmission 3 digital signals. Block the formation and transmission of the digital signal may be performed using known devices. As an example, such devices can serve as remote controls for remote control, performed on the chip encoders firm and HOLTEK chips transmitters firm RFM Inc., in particular, RFM TX5000.

According Fig.2A, the inverter charges contains the transformer 4, primary winding 5, which is the input of the Converter, and the secondary coil 6 consists of two windings having a common output, and by two half-cycle rectifier 7 is connected with the storage capacitor 8, which is the output of the Converter.

In Fig.2B shows the Converter charges made by the scheme shown in Fig.2A, and is complemented by a threshold element 9.

The Converter according to Fig.3 is executed in the form of a semiconductor structure having a substrate 10 of n-type epitaxial layer 11 of p-type. In the epitaxial layer 11 formed of a rectifying contact 12 made in the form of p-n junction and ohmic contact 13. The contacts 12 and 13 form the input of the Converter. The output storage capacitor 8 PR the drive 12.

In Fig.4 shows the Converter charge containing a set of n identical capacitors 15, which by means of the switching device 16 can be transformed into an Assembly with a serial connection of these capacitors, when all switches are translated into position I, or in an Assembly with the parallel connection of the capacitors, when all switches are translated into position II.

Block diagram, remote control of electrical devices, shown in Fig.5, comprises a generator 1 of the charges, the output of which is connected to the input of the inverter 2. The output of the inverter 2 is connected to the input electric power to the imaging unit 17 of the digital codes. The imaging unit 17 is controlled by a block 18 code selection, is connected to the input of the shaper 17. The output of the driver 17 is connected to the input of the transmitting device 19 of the control signals. Items 1,2, 17, 18 and 19 form the transmitter of the remote control. The receiving device 20 of the control signals output connected to the input device 21 processing and management, which in turn is connected by its outputs to the inputs of controlled electrical devices 22. Device processing and control can be performed using a known device such as a chip receivers Phi is atcic, the block diagram of which is shown in Fig.1, operates as follows.

When activated, the generator 1 charge it produces a portion of the electric charges q high electric potential Uin, which is fed to the input of the inverter 2. The function of the Converter is to increase the original value of the charge q to the value of Q and the accumulation of them on the inverter output potential Uout, smaller in magnitude than Uin. Work unit generation and transmission 3 digital signal is provided by an electric power from the resulting conversion of the charge Q at the input unit 3.

The converters shown in Fig.2A and Fig.2B, operate in pulsed mode. If the activation of the generator 1 of the charge leads to the formation of high-energy current pulse, when applying such a current pulse in the primary winding 5 of the transformer 4 through electromagnetic energy transformation of the pulse in the secondary winding 6 of the transformer 4 is induced pulse electromotive force (EMF). Since the number of turns in the secondary winding 6 is less than the number of turns in the primary winding 5, the amplitude of the EMF in the secondary winding 6 will be less than the amplitude of the input voltage, and the amplitude of the current in the WTO is cnom pulse is longer, than the charge q is enclosed in the primary impetus coming from the alternator charge. After rectifying the secondary current pulse to a full-wave rectifier 7 of its charge Q accumulated on the accumulating capacitor 8.

If the activation of the generator 1 charges cannot provide a short high current pulse, it is necessary to use a threshold element 9 connected in series with one of the terminals of the generator 1 charge and one of the conclusions of the primary winding 5 a pulse transformer 4 (Fig.2B). In this scheme of Fig.2B, the current pulse in the primary winding of the transformer is formed by the switch (breakdown) threshold element 9 when exceeding its voltage above a certain value.

The threshold element in this scheme may be made in the form of a tube with discharge gap or semiconductor structures, such as a thyristor.

Variant according to Fig.2B will be very effective in the performance of the generator 1 of the charge in the form of triboletti or radioactive source of charged particles. In such generators, electric charge corresponding to the potential at the output of the generator accumulates relatively slowly.

In the Converter, which is made on the basis of Polopos in Fig.3, a rectifying contact 12 includes aboutnomoney p-n junction, on the tank which accumulates the charge q produced by the generator 1 charge. When the voltage exceeds the p-n junction of the threshold voltage is the electrical breakdown accompanied by the birth of an avalanche of electron-hole pairs. Part of nonequilibrium charge carriers will flow in ohmic contact 13. However, if the resistance of the epitaxial layer 11 to make sufficiently large, the leakage current through the contact 13 can be made smaller than the current injection of electrons from signalisierung n-region of the substrate 10 in the vicinity of the contact 12, arise due to the spatial redistribution of electric potentials in the structure after the breakdown of p-n junction rectifying contact 12. The current injection of the substrate compensates for the current nonequilibrium holes, drifting from contact 12 to the side of the substrate 10 and will be charged through the rectifier 14 storage capacitor 8 to charge Q. Due to the fact that the number neravnovesnykh charges, born avalanche breakdown, many times greater than the charge q, previously produced by the generator 1 charge, such semiconductor Converter will operate as a multiplier Zaratustra, for example, a transistor or thyristor. The main requirement for this structure is that its input capacitance would be relatively small, that would allow to accumulate charge from the generator charges with high potential and after exceeding a certain threshold voltage to generate a current pulse breakdown of this structure with the formation process of avalanche multiplication of charge carriers.

The Converter shown in Fig.4, based on the switching of the set of elementary low-voltage capacitors 15 a container that implements a simple way to convert the size of the source charge q produced by the generator 1 charge.

A series connection of capacitors 15 (all switches 16 is set in position I) total input capacitance of the transducer is small and is defined as Cin=C/n, where C is the capacitance of each capacitor 15, a n - number of capacitors 15 in the Converter. If the generator 1 charge has developed a small portion of the charge q, the voltage at the input of the Converter is large and is defined as Uin=nq/C. due to the serial connection of each individual capacitor 15 will be charged the same charge q. When you subsequently install all switches 16 in position II all condense the poison of this capacity will be equal to the sum of charges of all of the capacitors 15, i.e. the value of Q=nq. The voltage generated at the output of the Converter, can be defined as Uout=Q/Cout=q/C=Uin/n. Thus, the structure behaves as a multiplier n times the charge q produced by the generator 1 charge, with a simultaneous decrease in n times of its potential at the inverter output.

The switches in the Converter of Fig.4 can be performed as with mechanical and electronic switching.

The control system shown in Fig.5, operates as follows. When activated, the generator 1 its charge is supplied to the Converter 2, is made with the possibility of increasing the initial amount of electric charges and the reduction potential of electric charges accumulated at the output of the Converter. The converted charge inverter output 2 to the input of the driver 17 and provides electrical power. Unit 18 the choice of codes is used to control the imaging unit 17 to select the appropriate digital code command from the remote control of electrical devices 22. Impact on unit 18 may be aligned in time with the moment you activate the generator charge. The generated digital code supplied from the driver 17 to the transmitting device 1 is after amplification is fed to the device 21 processing and management. In the specified device 21 is allocation information of the digital code of the remote control signal and generating control commands of electrical devices 22.

Thus it is possible to build systems of control, in which the transmitter of the digital signal will be made with the possibility of power from the generators of charge, such as, for example, piezoelectric elements, triboletti or radioactive sources of charged particles.

This feature is qualitatively affect the technology and design of remote control systems, and opens access to new technical solutions that are incompatible with the use of short-lived, requiring periodic maintenance of power supply for transmitter signal DN.

For example, the emergence of an existing market systems control lighting and other appliances unattended transmitters signals DN, made, for example, in the form of a traditional switch or standalone remotes will bring significant economic benefits associated with savings on service costs required at the present time and additional consumer qualities of goods. For example, for such items as remote to open the garage door, calls for apartments or country houses, off the accordance with the invention, can be embedded in walls, floors, hard to reach areas of various designs and constructions. This new quality is important when deploying computer security systems, data collection systems. For example, it is possible to build passive systems collect information about the number and location of vehicles at a garage sites by embedding piezoelectric radio sensors in the floor of the Parking space, so the impact of the car on it will activate the piezo sensor and to generate a corresponding information signal.

New features appear in the effective use of radioactive power sources on the basis of which you can create compact, durable beacon for orientation in space, or installed in marine navigation systems.

A very important application of transmitters remote control without batteries and accumulators in rescue and military equipment that allows you to create non-volatile device alerts or control, with the possibility of long-term preservation and use in severe emergencies.

In engineering structures, design of new machines and mechanisms, implementation of the invention is expressed in five of these structures.
