Description

The invention relates to information transfer control devices and can be used for collecting, processing, and transferring the state of objects separated on the ground, for example, a trunk line.

The purpose of the invention is to improve the accuracy and speed of control.

The drawing shows an electrical structural diagram of a telecontrol device of a trunk communication line.

The device contains a generator unit 1, a readout and comparisons unit 2, a transmission unit 3, a reception unit 4, an encoder 5, a decoder 6, an address determination unit 7, a modem block 8, a filter block 9, a display block 10, a control block 11, a block 12 logical and arithmetic operations, block 13 of the permanent memory, block 14 of the main memory, block 15 of the formation of the address, block 16 of the formation of the data and block 17 of the input-output of the information.

The device works as follows.

At the central (master set) and peripheral (slave sets) points, a linear telecontrol device of the same type is used.

The central point may be the management of the trunk line (zone) of communication. In the LAC, at compaction stations, device complexes should be placed on the radio relay and tropospheric stations. The devices are interconnected by the PM channel formed by the transmission system of the trunk line.

The functional control sensors contained in the transmitter, the receiver of a radio relay or tropospheric station (not shown), the termination and detection equipment of the seal are connected to the first input of the linear telecontrol device. After a certain period of time, the block 12 of logical and arithmetic operations on the program recorded in block 13 of the permanent memory forms the start copy. This command is supplemented by the addeamIi vedo

My kits from the block 14 are operative - 55 to these signals at the request of the 12 memory block. This array from the module of logical and arithmetic operations of the block 12 logical and arithmetically-formed array of the state of the site, their operations in the parallel code of the line. This array is entered in block 14

a data generation unit 16 and an address generation unit 15 are operated and fed to information input-output unit 17. Then the information is supplemented by the protective bits of the Hamming code and service marks in the encoder 5. In block 8 of modems, using block 1 of the generators, the information is converted into frequency-modulated signals. In block 9 of the filters, the signal spectrum is limited according to the voice telegraphy channel. Then the signal enters the transmission unit 3, from it to the first output of the device and further to the tone frequency channel. The response signal about the state of the line section of the peripheral stations arrives at the second input of the device. This signal passes. block 4 receive, block 9 filters and block 8 modems and enters the block 17 I / o information. With the permission of block 12 of logical and arithmetic operations, the information received from block 17 of input / output information enters block 7 for determining the address and block 16 for generating data. As a result of the matching of the received address with the address recorded in the RAM block 14, from the address determination block 7 a signal is sent to the control block 11, which generates a command to block 12

logical and arithmetic operations for entering information into it through the data generating unit 16. After processing the incoming message, the result of the control is recorded according to the corresponding. address in block-14 RAM. In the case of the registration of an emergency status of any of the objects, this information with the address (part number) from the RAM block 14 is output to the display unit 10 via the data generation unit 16. The control data in the display unit 10 is displayed immediately, and to the external computer via the second output is output on its request. In unit 2 of reading and comparing, signals are received through the first input of the device, SGod (unsuitable) of the state of the sensors, which fixes a specific parameter of the object. By

Operating memory ri is displayed on display 10. The tonal frequency channel through the second input of the device to each slave complect receives a message from the master kit. Frequency-modulated signals are received through the receiving unit 4, the filter unit 9 to the input of the modem unit 8. The transformed message in the form of telegraphic characters enters decoder 6, in which each character is encoded and checked for authenticity. Next, the request signals are received on the block 17 input-video information. With the permission of the address generation unit 15, the message enters the address determination unit 7 and the data generation unit 16. As a result of the analysis of the request signal in the address determination block 7, the -20 s command is generated for the control block 11. By this command, the message is entered through the data generation unit 16 into the logical and arithmetic operations unit 12, which generates the query command in the operational memory unit 14. In the block of logical and arithmetic operations 12, when receiving information from the RAM 14, a message is generated in the form of the address of the master set, the states of its sections and its address. This message is output via the data generating unit 16 to the information input / output unit 17 and then to the first 35 output of the device.
