vehicle works as follows.

The matching unit 20 at its outputs generates signals (FIG. 10) ensuring the operation of the units of the device consistent in time. The signal from the third output of the matching unit 20, which arrives at the second control input of the information processing unit 22, outputs information on the outputs of the latter for transmission to the air, arriving at the first group of information inputs of the 27o shift register. And the same signal opens the element 25 for passing clock pulses from the clock pulse generator 24 and a single-oscillator 26 is started, which generates a signal of parallel recording of information received at the information inputs of the first group of the shift register 27. From the output of the last information in the serial code (Fig.Z) is fed to the input of the modulator 28. From the output of the modulator 28, the signal is fed to the input

transceiver 18 of the first channel, which ensures the conversion of logical O and 1 into modulated radio signals. These signals received by the two-channel transceiver 6, through the switch 2, arrive at the demodulator 31 and are converted into a sequence of logical O and 1. Upon the arrival of the starting pulse (FIG. 3) of the request waveform, the signal O allows the counter divider 32 to work. by condition

where Tg is the period of the frequency of the following pulses from the generator of 30 pulses;

The coefficient of the decoder 34 t, is selected by the condition Fr

where is the frequency of the 3G generator;

Ј - the speed of information peredachi ,, bps.

Counter 35 counts the number of bits of information after the start. The decoder counter FOR generates at its outputs signals corresponding to the state of the counter. From the first output, the strobe signal is incident to the middle of the bit. When the reception of information on the output of the counter 35 is turned on, a signal appears that ensures the switching of the trigger 33 to the initial state, i.e. translation of start-up block 3 to the initial state.

The following signals are received from the demodulator 31 output — codogram in the sequential code, the scheduling pulses from the first output of the counter-decoder 34, the termination signal of the information reception — from the output of the counter 35 „

From the first output of the start check block 3, the information input of the shift register 36 receives information in a serial binary code. The recording of information in shift register 36 starts from the first bit of the codogram following the start. Under the action of the strobe pulses coming from the second output of the start-up checker 3, the shift register 36 is filled with information transmitted from the control point (N, L G). The bits of the shift register 36, into which the 5 gives the transmitted number, are each connected to the first input of the corresponding element 38 EXCLUSIVE OR, the second inputs of which are connected via the switch 41 to the 0 O or k buses, depending on the coded grab number. elements 38 EXCLUSIVE OR b / dUO only if the number in the request- 5 codogram coincides with the coded number on the vehicle (coded using switches 41). Then the termination signal for receiving information from the third-G of its output of the start-up checker 3, after passing through the NOT element 37, generates a strobe signal at the output of the OR-NOT 40 element for recording information into the parallel register 39 from the shift register 36 (in the case of vehicle numbers). With this signal, the vehicle equipment is transferred to the information transfer mode. The bit in the parallel register 39, 0 responsible for the driver’s voice communication is connected to the control unit 7, and the remaining bits of the parallel register 39 are connected to the inputs of the digital-analog converter 8. 5 ° The operation of control unit 7 is described by a truth table:

a - the value of the signal from the tangent

12 (1 - pressing | 0 - release); b is the value of the signal from the sensor 14 of the position of the handset 13 (1 is the tube is picked up; O is the tube inserted into the handset);

C is the signal from the trigger generator 5 (1 is active; O is passive);

d G - call information from block 4 (1 - there is a call; 0 - there is no call);

- radio station mode function (1 - reception; 0 - transmission);

- channel switching function of transceiver 6 (0 -1 channel; 1 channel 2);

- the function of switching on the sound signal (1 - signaling is on, 0 is off).

When operating on the first channel, a two- and channel transceiver 6 operates in the mode of receiving and transmitting digital information and its first input and output are connected via switch 2 to the output of the coding unit 10 and the input of the start verification unit 3

When switching a two-channel transceiver 6 from the first channel to the second first input and its output by means of the switch 2 are connected respectively to the output and input of the handset 13.

The processing of information arriving at the monitoring point and the formation of the information transmitted to the vehicle are carried out in accordance with the flowchart of FIG. 8 and 9.

After starting the program, information processing unit 22 (microcomputer) performs a number of preparatory operations (1–8 blocks of the algaritm block diagram). For- by block 9, the readiness of the equipment at the monitoring station to the request mode of the 1st vehicle is performed. A ready flag is set by matching unit 20 at the second input. When the output of the information processing unit 22 receives information (N ;, &;G;). From the output of the coding unit 21, the tone signal of the frequency (phase) modulator comes to the input of the transceiver 18 of the first channel. At this time, the vehicle's equipment, operating in the information receiving mode, detects the start signal and compares the number in the request codogram with its number. The vehicle whose number matched the number sent by the control point receives the codogram. The information received on the vehicle contains information about the deviation from the schedule and the command to the board about the call to voice communications.

When the device operates in the first cycle (), the deviation and the command about

the call will have zero values (i 0-n). In accordance with this, the deviation indicator arrow will be set to the neutral position - 0, and the call to voice communication will not follow. After receiving the information, the equipment of the 1st vehicle is transferred to the information transfer mode. At this time, the equipment at the monitoring point is awaiting the readiness flag to enter information into the microcomputer memory. After receiving information from the 1st vehicle from the outputs of the serial code converter 19 to the parallel received information MJK,, K-K enters the information processing unit 22. This information is processed sequentially according to the algorithm of the program, after which the following transport is polled. ny means. The received information in subsequent cycles determines the location of all vehicles on the route. According to the location of the vehicle, the planned residence time at a given point of the route is determined from schedules (by interpolation by given control points from schedules). Then, if the location of the vehicle corresponds to the location of the control point on the route, then treKn is entered into the traffic generation array of the 1st vehicle (blocks 27 and 28, the flow chart of the algorithm). For the planned time and the current, the deviation from the 1st vehicle's schedule is determined and entered into the information output buffer for the i-th vehicle in L ;. Subsequently, this information, having entered the vehicle, is displayed on the deviation indicator.

For the voice communication of the dispatcher with the driver, the number of the vehicle is dialed on the microcomputer's keyboard. A keyboard interrupt is made and the program goes to the start address of the keyboard interrupt handling routine. The subroutine defines the number of the vehicle in cycle i and Gj is assigned the call value. Prin in this information, equipment

The 1st vehicle triggers in this way. When the handset 13 is inserted into the tube holder, the microtelephone 51 of the control unit 7 starts to emit a beep. When the tube 13 is raised, the beeper stops and the two-channel transceiver 6 switches to the second channel. The voice communication is carried out with the dispatcher through a virtual channel transceiver 23 of the second channel, the Docne rean connection is connected to the driver by inserting the microtelephone tube 13 into the keyboard, the holder, and the dispatcher typing on the keyboard the reset symbol xgand. When the initiator of a seapes connection, the owner of the driver sends a call to the phone using the keyboard 17 on the vehicle. This information received at the monitoring station will be transformed Ј command to the dispatcher on the liquro-computer display screen. Then the dispatcher performs the described operations to perform voice communication. zi
