Description

The invention relates to radio engineering and can be used in remote control systems for receiving discrete messages.

A well-known system for transmitting discrete messages with information feedback containing a binary signal receiver, a raielichator, a shaper of code combination elements, a comm-.op, a register block, a memory block, a service sign decoder and a reverse channel transmitter ST].

The closest in technical essence to the proposed one is a device for receiving discrete messages in a system with information feedback, containing a receiver whose output is connected to the input of the signal conditioning unit, one output of which is connected through the decoder to the first input of the switch, the second output is connected to the second the input of the switch, the first output of which is connected to the input of the first register, the second output is connected to the first input of the second register, the second input of which is connected to the first output of the first register tra memory unit [2].

However, these devices cannot receive the next message code combination until the Execute command is received. In turn, this team; It is transported by the forward channel transmitter only after receiving the receipt on the return channel. As a result, between the transmission of the code combination of messages and the Execute command, a pause is formed, the duration of which is equal to at least the duration of the receipt. This leads to a decrease in the forward channel transmission rate.

The purpose of the invention is to increase the speed of the device.

This goal is achieved by the fact that in the device for receiving discrete • messages in a system with information feedback, a distributor of even combinations, a distributor of odd .. combinations, an element And, inputs of distributors of odd and even combinations are connected respectively to the second output of the first register and the output of the second register,; the first inputs are connected to the first and second inputs of the memory block and, respectively, to the first and second input of the element And, the third input of which is connected to the output of the memory block, the corresponding inputs of which are connected to the corresponding outputs of the distributors of even and odd combinations.

The drawing shows a functional diagram of the device.

The receiving device consists of a receiver 1, a signal conditioning unit 2, a switch 3, registers 4 and 5, a decoder 6, an even combination allocator 7, an odd combination allocator 8 and a memory unit 9. The output of the memory unit 9 is connected to the decoder via an AND 10 element.

The device operates as follows.

The voltage from the receiver 1 is supplied to the signal generation unit 2. The generated first code combination of messages through the switch 3 goes to register 4. The next message combination shifts the first combination to register 5, and it is written to register 4. After receiving two consecutive code combinations of the message, switch 3 turns on the decoder 6. The first combination of the service mark through the switch 3 acts on the register 5. If block 6 makes a decision on the presence of the sign YES, then the information from the register 5 goes to the odd distributor 8 combinations, and register 5 is cleared. If the decoder b makes a decision about the presence of the NO sign, the information in the register 5 is erased, and the signal is not received in the corresponding memory cell of the distributor 8. The second combination of the service mark following it performs similar operations with the information of register 4, transferring it to the dispenser 7 of even combinations. The memory cells of the allocators 7 and 8 are connected to the corresponding memory cells 9. As soon as the first and second cells of the memory unit 9 are full, a command is sent to the inputs of the element And 10 and the information from the memory unit 9 goes to the decoder.

The use of a device for receiving discrete information in a system with information feedback allows one to increase the transmission rate of messages on a forward channel without significantly complicating the circuit.

(54) DEVICE FOR RECEIVING DISCRETE MESSAGES IN AN INFORMATION REVERSE SYSTEM The invention relates to radio engineering and can be used in telecontrol systems for receiving discrete messages. A known system for transmitting discrete messages with an off-line information communication system includes a binary signal receiver, a discriminator, a code pattern generator, a switch-switch, a register block, a memory block, a service sign decoder, and a reverse channel transmitter til. The closest in technical essence to the present invention is a device for receiving discrete messages in a system with information feedback, containing a receiver, the output of which is connected to the input of the signal-generating unit, one output of which through the decoder is connected to the first input of the switch, the second output is connected to the second , to the switch input, the first output of which is connected to the input of the first register, the second output is connected to the first input by the LINK of the second register, the second input of which is connected to the first output of the first th register, a memory block. However, these devices cannot receive the following code message & message message until the command completes. In turn, & that team. It is transported to the forward channel transmitter only after receipt of the receipt via the ofat channel. As a result, there will be a pause between the transfer of the code combo of messages and the command of the Execution, the duration of which is, at least, the duration of the receipt. This results in a decrease in the transmission rate on the forward channel. The invention is aimed at improving the speed of the device. The goal is achieved by introducing an even combination distributor, odd combiner, combinations, element I, inputs of distributors of odd and even com- pounds of the first register and in the device for receiving discrete messages in a system with information feedback. output of the second register,: the first inputs are connected to the first and second inputs of the memory block and, respectively, to the first and second inputs of the And element, the third input of which is connected to the output of the memory block, with Resp EKODY which soedinens sootvetstvuyushimn with outputs of even n odd valves com nations. In the drawing isofaza functional diagram of the device. The reception device consists of receiver 1, signal conditioning unit 2, switch 3, registers 4 and 5, decoder 6, distributor 7 even combinations, distributor 8 odd combinations and memory block 9. The output of memory block 9 is connected to the decoder via the AND element 1O. The device works as follows. The voltage from receiver 1 goes to signal shaping unit 2. The first formed code combination of co-ops comes through register 4 through register 4. The following message combination shifts the first combination to register 5, and itself is recorded in register 4. After receiving two code numbers combinations of co & switch 3 turns on decoder 6. The first combination of service mark through switch 3 affects register 5. If block 6 decides whether the sign is YES, then information from register 5 goes to distributor 8 tnyh combinations register 5 and purified. If, on the other hand, the decision on the presence of the NO symbol is decoded by the decoder 6, the information in the register 5 is erased, and the signal is not received in the corresponding memory cell of the distributor 8.
