Abstract

The invention relates to telecommunications and can be used to receive telecontrol and communication signals on unattended, limited-power facilities. The aim of the invention is to reduce energy consumption. The essence is to reduce power consumption by keeping the device’s power supply unit turned off and operating from the drive while maintaining the sign of this bit in the next command, practically no energy is required to install it, as well as limiting the duration of the response pulse of the recording unit after it is triggered. 1 ill.

Description

The invention relates to the field of telecommunications and can be used to receive telecontrol and communication signals at peripheral maintenance-free facilities with limited power consumption of the receiver.

It is an object of the invention to reduce energy consumption.

The drawing shows a functional diagram of the device.

The device comprises a start and clock pulse generating unit 1, a distributor 1, a decoder 3, first and second power amplifiers 4 and 5, a bistable memory element 6, an independent power supply unit 7, an energy storage unit 8, an element 9 NOT, blocks 101 .. .10m registration.

The registration unit contains elements 11 And 12, power amplifiers 13 and 14, a bistable memory element.

The bistable memory element is implemented, in particular, on a polarized relay 15 with two windings and two / one / 16

and 17 contact groups, the energy storage unit is carried out, in particular, on a capacitor 18 charged / recharged / through diodes 19 and 20. The bi-active memory element 6 contains a contact group 61.

The device operates as follows.

An information signal through glement 9 is NOT supplied to the input of the start and clock pulses forming unit 1, the reset output and the control / clock / outputs of which are connected to the corresponding inputs of the distributor 2, the last output of which is connected to the control / off / input of the unit 1. With the receipt The first information pulse by the trigger 21 of block 1, the generator 22 of this eloq is started and the distributor 2 is reset.

Block 1 begins to generate control / clock / pulses, with the arrival of a pulse from the last output

distributor 2 block 1 stops producing them.

Information signals directly and through element 9 DO NOT enter the first inputs, respectively, of the first and second elements And 11 and 12 in the registration blocks 10i ... 10M, the second inputs of these elements And receive enable pulses from the corresponding output of the distributor and to the third inputs of these elements And - enable or disable voltage, / dl of the corresponding elements and 12 / through the contact group of the bistable memory element. The signals of unity and zero from the information input at the corresponding time moments determined by the distributor pass through the element And 11 and 12, which is open at the third input, switches the bistable memory element, and then the corresponding element controls the voltage of this element And it closes. This opens another of the elements And 11, 12, which will miss the opposite information signal - before it arrives, both elements And are closed. In this case, both power amplifiers 13 and 14 are provided, and the bistable memory element maintains the acquired state.

The stored signals from the outputs of the registration units are fed to a decoder 3 / logic matrix /, from the outputs of which, according to the last clock pulse supplied to the control input of the decoder 3 from the distributor 2, information is acquired.

In addition, from the moment the signals arrive at the inputs of the decoder until the information is taken through the power amplifiers 4 and 5, a bistable memory element 6 is turned on, which performs an autonomous power supply unit 7. The output of this unit and the information input of the device are connected to the corresponding inputs of the energy storage unit 8, which stores energy from both the information signals and the autonomous power supply unit 7, and this unit 7 is used to power circuit elements, in particular, power amplifiers.

Due to the fact that the power amplifiers 13 and 14 of all the recording units are turned on only for the switching time of the bistable element, significantly shorter than the signal duration, and additional energy is accumulated in block 8 from the information signal (for example, by charging the storage capacitor). the power consumption of the stand-alone power supply unit 7 is reduced.
