The number K is equal to the number of control points in the device.

The number of elements 29 And in block 4 of information processing is determined by the product of the number N of parcels constituting the impulse series of parcels by the number M of transmitted pulsed cepiw.

The number of memory nodes 44 in the code analysis block is determined by the number M, the pulse series of packages, and the number of elements 48 AND is equal to the number N of packages made up of a single pulse series.

The number of elements is 59-65. And in block 5, the code analysis is selected based on the maximum possible mismatch between the actual time of arrival of the vehicle at

control point and planned and determined by the number P of the binary bits of the reversible counters 54 and 55, necessary for counting in minutes this rasslohl with the first yhoda

elements 62 And made inverse.

The device works in two modes. max: the mode of automatic exchange of digital information between vehicles and the control point and the mode of telephone communication of the dispatcher with the drivers of vehicles; The main mode of operation of the device is the mode of automatic exchange of digital information; In this mode, the programmer 17 in accordance with the program embedded in it, establishing the order of connecting the communication lines going from different control points to the control point 5 generates a control signal for the switch 11. In this case, the communication line goes but from a well-defined control point, switch 11

connects to the selector 12; at the same time, a Request signal is sent to the specified link ™ from the programmer 17, which through the transceiver 9 of the control point enters the inductive communication channel. In addition, from the programmer 17 to the analysis unit 13, a signal is supplied that establishes the operative memory of the latter in O.

If, when transmitting a request signal, the vehicle enters the zone of operation of the transceiver 9 of the checkpoint 9, the transceiver 2 of the latter receives the signal

The request and submits it to the launch block 3, which starts the block of information processing 4.

Information processing unit 4 generates code information consisting of M pulsed series, each of which includes N parcels and represents information transmitted from a vehicle. The coding of the elementary parcels of signals is carried out according to several mutually independent code features, for example, duration and frequency filling. From the information processing unit A, the generated code combination enters transceiver 2, which by means of an antenna radiates it into an inductive communication channel. At the control point, the said code combination is received by the antenna of the transceiver 9, which transmits it to the control point 10 on the communication line.

At control point IO, the code information passes through the cell of switch 1, corresponding to the control point, and enters the selector 12, where the elements of the received combination are separated according to code features, after which it enters the code analysis unit 13. In this case, from block 3 of code analysis, the programmer I7 receives a signal to prohibit the switching of communication lines.

In block 13, the code analysis sets the character reception threshold, accumulates the values of each of the N sums in the M pulse series and compares elementwise the number of that number with the specified threshold. At the same time, in block 13 of code analysis, the entire code combination with the chain of matching it with one of the code combinations received for coding information transmitted from the transport means is analyzed. When this correspondence is established, the code combination is received for registration, and in the modulator 1A a confirmation signal is received. The confirmation signal passes through the element 18 and enters the selector 2.

In addition, after the analysis, the code combination arrives at one of the inputs of the analysis block 15, to the other inputs of which I6 sets the signals corresponding to the planned arrival time of the vehicle at the control point. The analysis unit 15 determines whether the actual time of the transport unit arrives at this control point against the planned one and generates a mismatch signal, which through element 18 OR enters the selector 12, From the output of the selector. 12 signals to acknowledge the receipt of information and the mismatch of the actual time of arrival of the vehicle; the control point with the planned one through the switch I1 passes through the communication line and enters the transceiver unit 9 of the control point, which transmits them to the inductive communication channel.

From the communication channel, these signals are received by the antenna of the vehicle's transceiver 2. From the output of the transceiver 2, these signals go to information processing unit 4, where they are detected by code and decoding, from there they pass to display unit 7, informing about deviation from the established schedule of movement, and in block 6 of the display, informing about the reception of signals at point 10 of the control.

After these signals are transmitted to the vehicle from the programmer 17, supplied from analysis block 13, the signal is removed and the next control point is polled by ano- logy with the above.

If, during signal transmission, the vehicle does not have a request in the coverage area of transceiver 9 of the checkpoint, the code combination is not received in analysis block 13 and the line switching prohibitance signal is absent. At the same time, the programmer 17 removes the signal to connect the next communication line to the selector 12 and delivers it to the switch 11;

When the device is operating in the telephone mode of the dispatcher with the driver of the vehicle, the establishment of the communication is possible as per initial; tive manager, and on the initiative of the driver.

When establishing communication at the initiative of the driver, the latter, using speech signaling unit 5, forms

The signal is called Call for communication, from which it goes to the information processing unit A, where it is encoded.

The transmission of the call signal to the communication point 10 of the control is carried out according to the described scheme together with the rest of the information transmitted from the vehicle.

.At the control room, the call-to-end signal is made by the selector 12 and enters voice signaling unit 19, signaling to the dispatcher that it is necessary to establish communication with the designated vehicle at this control point. The dispatcher connects the speech signaling unit 19 via the switch 11 to the line from which the call was triggered to the telephone and communicates with the driver of the vehicle; In this case, from the speech information block 19, the interrogation program task block 17 is prohibited from switching lines during a telephone conversation.

At the end of the telephone conversation, the dispatcher disconnects the voice information block 19 from the communication line and the prohibition from the task block of the interrogator 1 7 is removed.

The device is ready to poll the next control points.

When establishing telephone communications on the initiative of the dispatcher, the latter connects the voice information block. I 9 through the switch P to the communication line going from the control point with the vehicle on it, the driver of which needs to send an emergency message, and communicates with it.

By analogy with what has been stated in the programmer 17 from the speech signaling unit 19, the line switching prohibition signal is given for the duration of the telephone conversation.

At the end of the telephone conversation, the dispatcher disconnects the speech signaling unit 19 from the communication line, the prohibition from the I7 programmer is removed and the last sign of the connection of the selector 2 to the next control point.

In block 4, the processing of information upon the arrival at the first input of the trigger 20 of the signal. The trigger is turned on for counting times. With

arrive at the descrambler 32 and at its outputs alternately pulses arise, the duration of which is equal to the duration of the elementary dressings received for the exchange of information and,

The proposed device and the outputs of the decoder 32, which are involved in the formation of pulse series, are transmitted to one of the inputs of elements 29, And., 29N And, to other inputs

which are supplied from the outputs of the encoder 30 to the frequency of filling of elementary streaks of signals. The encoder 30 provides information coding in accordance with the vehicle code. The pulses appearing at the outputs of the first two elements 29 AND are filled with the frequency fj, 00 corresponding to the synchronization signal. Impulses arising at the outputs

the subsequent elements 29 AND, are filled with one of the frequencies f, or f, depending on the vehicle number code, and at the outputs of the elements 29 AND, M code

combinations (pulse series), each of which consists of N parcels and carries information about the number of the vehicle.

After the formation of code combinations carrying information about the vehicle number, a dispatcher output signal to the telephone is generated. When applying to the third, the call signal block input turns on the trigger 21 and the frequency 24 passes through the elements 24, 25 I to the first block output, the presence of which at this code position indicates the need for a telephone conversation with the driver of the vehicle.

At the end of the formation of the pulse series, the binary counter 31 continues to operate, and at the outputs of the decoder 33 gating pulses are formed, participating in the recording of information received on the vehicle, about compliance with the actual traffic schedule

those that come to the second input of the block are allocated by the selector 36 and arrive at the second inputs of the elements 26, 27 And, to the first inputs of which receive the pulses from the decoder 33.

When the indicated signals coincide at the inputs of the elements 26,27 And the strobing pulses pass to the outputs of the indicated circuits and turn on the corresponding cells of the memory node 38. From the output of the memory node 38, the signals are sent to the decoder 34, at the output of which there appears information on the compliance of the actual time of arrival of the vehicle to the control point with the planned one.

The confirmation signal is selected by the selector 37 and is fed to the second input of element 28 I, the first input of which is sent a strobe signal from the decoder 33. When these signals coincide, the inputs of element 28 And the strobe signal passes to the first input of memory node 39 and turns it on . At the same time, an output acknowledgment signal appears at the output of the memory node 39.

From the outputs of the decoder 34 and the memory node 39, signals are sent to the imaging unit 35, which reveals the formation of the reset time of the memory nodes 38 and 39.

The time lag is determined from the perceptions of the drivers of the received information.

Upon completion of the formation of these signals, the counter 3 returns to its original position, and a reset signal is generated in the O flip-flops 20 and 21. The circuit returns to its initial state before the next Query signal arrives.

In block 13, the codewords are transmitted from the transport unit. From the output of the selector 12, the synchronizing signal, which determines the beginning of reception of the pulse series, triggers, with re iepjiTop, 40 pulses, generating clock pulses that control the distributor 41, at the outputs of which write pulses are generated.

units of transport information deviating from the established timetables, which are fed to the fourth output of the block.

In Stock 15 of the analysis, signals from the output of the setting device 16, consisting of the amni-tions of the time-setting settings, the arrival of the vehicles and the checkpoints, go to the second group of inputs of the switch 51.

When receiving the number of the vehicle located at a certain checkpoint, from the analysis block 13, the vehicle number code is sent to the second input of the station 50, and from the Programmer 17 to the first input of the analysis block 15 - its location code ((control number point) at certain points. The registrar 50 contains counters that count the number of vehicle receipts for each control point. When a vehicle’s vehicle number and position is received at the inputs of node 50 being from the outputs of the recorder 50 to the first INPUT group of the switch 51, a signal is received that permits the passage of the planned time code of the arrival of a certain vehicle to the data checkpoint through the code converter 52 to the input of the subtraction of the forward counting counter 55 and the delay time counting input 54 schedule. At the same time the beginning of the signal number of the control point arriving at. the second inputs of elements 59 I are allowed to pass the code of the actual arrival time of the vehicle to the datant control point, generated by timer A9.
