The local information block is connected to the fourth output I, respectively, to the third input of the control unit, and the third output of the interrogation unit and local information is connected to the nepBoi- / iy input of the print unit, the second input of which is connected to the fifth output of the control unit} the sixth output which is connected to one of the inputs of the fixing unit of the information sign, its other input is connected to the second output of the linear j receiver

information, the third output of the latter is connected to the first input of the print unit, the output of the fixing unit of the information sign is connected to the second input of the selector and turn on the display, one of its outputs is connected to the signal board, and the other to one of the inputs of the alarm and accident control unit The other input of this block is connected to the electric clock, the manual data input block is connected to the commutation unit.

The drawing shows a functional diagram of the proposed device for control; the object being rotated and the control station connected by a communication channel.i

The device contains installed on the cargo controlled object telephone 1, information transmitter 2, information receiver 3, through the input unit 4; connected by subscriber lines 5 with block

switching 6, installed at the control tower.

At the dispatching station, besides the switching unit 6, an information transmitter 7, a block, local information 8, a polling unit and issuing local information O, a printing unit J.O, a control unit 11, a linear information receiver 12, an information sign latching unit 13, a block are installed.

for selecting and turning on the display 14, the signal board 15, the alarm unit and emergency records 16, the manual input unit 17. The local information block contains a schema, object numbers 18, HOKiepa message 19, and the transmitter 7 is equipped with a reception control circuit 20. Scheme of the current time 21 and the signaling and accounting unit for emergency situations 16 are connected to the electric clock.

The device works as follows. To transmit the encoder information. the worker of the monitored object switches the line from the telephone to the transmitter of information 2. If

the device is not occupied by the reception

information from another object and is in the initial state set for it, then a signal from the switching unit 6 through the control unit 11 turns on the polling and issuing unit of local information 9, which captures data from circuits 21, 18 and 19, respectively object numbers and message numbers.

After the end of the local information on the signal from the control unit 11, the transmitter 7 is switched on via the switching unit 6, subscriber lines 5, the input unit 4 and the information receiver 3, issuing to the line the connecting object

signal to begin transmitting. Having received the permission signal, the worker of the object starts the transmission, and after its termination waits for receiving the permission signal to disconnect from the line. The incoming information is transmitted through the switching unit 6 and the control unit 11 to the receiver and other information 12, where it is decrypted and outputted to the print unit 1 O by commands from the control unit 11, which generates print commands.

A sign recognized by the receiver of the linear information 12 is outputted in the blocking of the indication of the information 13, from where it is combined with the information about the object number (from the object number scheme 19 of the local information block 8) and goes to the selector and turn on the display 14 to turn on the corresponding lag. scoreboard 15.

When a sign of information about an emergency situation on a VC object is recognized in the selector and turn on the display 14, the alarm and accounting unit 16 reads this situation — the acoustic alarm system is briefly activated, while the number of s / PGcams is activated and the duration of such a situation starts this object.

Turning off the alarm on the board 15 and taking into account the emergency situation for this object in block 16 occurs as the information from the objects about a change in the situation arrives.

When the receiver recognizes the linear information 12 of such a message from the object, it sends the corresponding signal to the control unit 11, which includes the 2 O transmitter of information 7, issuing through the switching unit 6 to the subscriber line 5 the transmission to Disconnection from the line if no device malfunction has been detected.

At the same time, they issue a command signal to the message number 19 scheme for preparing the next sequence number of the message.

When fixing the failure of the device, the signal in the message number circuit 19 from the information transmitter 7 is not issued. In this case, the message must be transmitted again from the object and received under the same number. After disconnecting the monitored object from the line, the circuit

The entire device is reset and ready to receive information from other station objects. When it is necessary to carry out telephone communication with the dispatching station, the order of

1 is established and negotiation remains the same as with conventional on-line telephone communication.

With the help of the block 17, the manual entry is carried out on the signal, board 15 and print unit U - the information coming from the controlled objects that do not transmit them in a coded form. At the time of data entry by the dispatcher, the receipt of information from controlled objects is excluded.
