Abstract

FIELD: traffic control devices. SUBSTANCE: control unit sends through first channel encoded requests. Each request contains starting packet, code of vehicle serial number, deviation of identified vehicle position from schedule and command for speech connection request. When request finishes, vehicle sends encoded answer, which contains either marker code, code of vehicle position and command for speech connection request, or code of mode for measuring specific resistance of traffic to motion of vehicle and codes of vehicle velocity in start and end of road part being controlled. First register, which serves as input, and second register, which serves as output, with control circuit are introduced in receiving unit for encoded information from route sensors. This results in possibility to increase validity of receiving. Encoded information from route sensors is represented by their double numbers in paraphase code, if encoded information from route sensors is received several times (five times, for example), it is stored in output register. When vehicle is located out of range of consistent reception of encoded information from route sensors, then paraphase conditions for testing are violated. This prohibits storage of false information in output register. EFFECT: increased information capability. 4 cl, 16 dwg

 A device for monitoring the movement of vehicles works as follows.

Block 24 matching at its outputs generates signals (Fig. 8), ensuring coordinated in time operation of all blocks of the device. According to the signal from the 3 output of the matching unit 24, which is received at the second control input of the information processing unit 26, data is transmitted to the output port of the latter. This data is fed to the first group of inputs (D ₁ .D _i ) of parallel loading of the shift register 70 (Fig. 9), the second group of which is constantly fed with logical zeros (D _{i + 1} .D _n-1 ) of the starting premise and the logical unit ( D _n ) stop parcel. The control signal from the 3 outputs of block 24 is triggered by a single-shot 68, which provides parallel loading of the data of the inputs D ₁ .D _i both into the register and through the And 67 element, which allows their shift to the higher bits with a generator frequency 66 equal to the data transfer speed in the first communication channel. The bits of the interrogation codogram (Fig. 10) sequentially appear at the output Q _{n of the} register 70 and the frequency signals f ₁ and f _o corresponding to logical levels of zero and one. From the output of the frequency modulator, the codogram is fed to the modulation input of the transceiver 22 and is broadcasted by its antenna in the form of FM radio signals corresponding to logical zeros and units of the codogram on the carrier F ₁ .

t_старта•Ft (1) где Т_т и F_т период и частота тактовых импульсов генератора 72, t_старта длительность стартового импульса запросной кодограммы. По приходу стартового импульса, удовлетворяющего условию (1), на выходе счетчика-делителя 74 появится импульс, переключающий RS-триггер 75 в нулевое сос- тояние, что разрешает работу счетчиков-дешифраторов 76 и 77. Коэффициент деления счетчика-дешифратора 76 М1, соответствует условию
M_I=

(2) где F_r- частота генератора 72,
F_n скорость передачи данных, счетчик 77 подсчитывает количество бит информации после старта. Счетчик-дешифратор 76 формирует на каждом j выходе (0 ≅ j ≅ m₁) сигнал логической "1", соответствующий коду внутреннего состояния. При этом "1" с выхода (i₁) соответствует середине длительности битовой посылки. По окончанию приема запросной кодограммы на выходе i₂ счетчика-дешифратора 77 сформируется сигнал, переводящий RS-триггер 75 в исходное состояние, запрещающее работу счетчиков-дешифраторов 76 и 77, то есть блок 3.1 проверки старта переключается в исходное состояние.These signals received by the vehicle’s two-channel transceiver 8 (TC), through the switch 2 are fed to the start check block containing the generator 72, the input of the block is the input of the demodulator 73 (Fig. 11) of the first start check block and are converted into a logical sequence “0” and "1". Upon the arrival of the start pulse (Fig. 10) of the interrogation codogram, the signal "0" enables the operation of the counter-divider 74, the division coefficient of which is selected from condition n

_start t • Ft (1) where T _t and F _{t are the} period and clock frequency of the generator 72, t _{start is the} duration of the start pulse of the request code. Upon the arrival of a start pulse satisfying condition (1), a pulse appears at the output of the divider counter 74, switching the RS flip-flop 75 to the zero state, which allows the operation of the counter-decoders 76 and 77. The division coefficient of the counter-decoder 76 M1 corresponds to condition
M _I =

(2) where F _r is the frequency of the generator 72,
F _n data transfer rate, the counter 77 counts the number of bits of information after the start. Counter-decoder 76 generates a logic “1” signal corresponding to the internal state code on each j output (0 ≅ j ≅ m ₁ ). In this case, “1” from the output (i ₁ ) corresponds to the middle of the duration of the bit sending. At the end of receiving the request code, at the output i _{2 of the} counter-decoder 77, a signal is generated that transfers the RS flip-flop 75 to its initial state, which prohibits the operation of the counter-decoders 76 and 77, that is, the start check unit 3.1 switches to the initial state.

The following signals are received to the vehicle number comparison unit 6 from the start check unit 3.1: from the output of the demodulator 73, the request code in the serial code at the logic levels “0” and “1” is the gate pulses from the first output (i ₁ ) of the counter-decoder 76, the signal the end of receiving the request code from the output (i ₂ ) of the counter 77. The request code from the output of the demodulator 73 in a serial code is fed to the serial data input of the register 78 of the vehicle number comparison unit. The sequential recording of data in the register is carried out by the clock signals of the second output of the start check block 3.1, the number of which is equal to the number of information bits of the request code, and the frequency to the data transfer frequency. As a result, the register 78 is filled with codes N, ± Δ, G. The code (N) of the TS number of the request code is bitwise connected to the first (A) group of inputs of the digital comparator 80, the second (B) group of inputs of which are supplied with the corresponding bits of the number of this TS specified switches P1.Pr (79). The value of B _i equal to zero or one (in accordance with the codes of the vehicle number) is set by connecting the group B input of the register to the "0" or "1" buses. The logical “0” value is supplied to the cascading inputs “greater” and “less”, and the level of the logical unit is supplied to the cascading input, “equality”. In this case, when the codes A and B of the operands coincide (the TS number in the request code N and the number specified by the switches is 79), a logical “1” (otherwise “0”) appears on the output of the comparator QA B, which is gated to the AND element 82 by the end signal i ₂ receiving the request code from the output 3 of the block 3.1. The vehicle number comparison unit in comparator 80 performs signal comparison.

The conjunction QA BΛi ₂ provides for the rewriting of deviation data from the movement schedule and voice communication call (VZVTL) from the outputs of the shift register Δ ₁ . Δ _p , G into the same bits of the register 81, for which the mentioned outputs of the register 78 are respectively connected to the D-inputs of the parallel loading of the register 81, and the recording strobe from the output of the element And 82 is fed to the C-input of the parallel loading of the register 81 and to start the shaper 5, Switching the vehicle equipment to the data transfer mode.

The output G of the register 81 is connected to 1 input of the control unit 9 and at G 1 it switches the transceiver 8 to a speech radio channel (carrier F ₂ ) for radiotelephone communication in simplex mode. The group of outputs of the register 81 is connected to the DAC (block 10) and provides an indication using the device 17 deviations of the vehicle from the traffic schedule.

 The operation of control unit 9 is described by a truth table in which the following notation of arguments and functions is accepted: and the signal value from tangent 15 (1 tangent pressed, 0 released); b the value of the signal of the sensor 16 position of the handset (MT) 14 (1 tube taken, 0 tube inserted into the tube holder); s signal from driver 5 of the start signal (1 active; 0 passive); α- call the vehicle driver for voice communication (1 call there, 0 no call); X function of the radio station mode (1 reception; 0 transmission); Y function of switching channels of transceivers (0 first channel, 1 second) Z function to turn on the audio signal (1 alarm is on; 0 is off).

 Using Carnot maps, minimized algebraic expressions for X, Y, Z-functions are found.

 The block diagram 9 corresponding to these algebraic expressions is shown in FIG. 13, where the logic elements 83, NOT 84, AND-NOT 85, AND 86, 87 are the 2-OR-88 ambiguity, generator 89, electronic key 90, and the handset 91 provide an audio signal at Z 1.

 When the transceiver 8 is on the first radio channel, the data channel (Y 0), its modulation input is connected to the output of the encoding unit 13 in the "transmission" mode (X 0), while the transmitter (Rx) is turned on and the receiver (Rx) is turned off. In the “Receive” mode on the first channel (Y 0, X 0), the low-frequency output of the receiver is connected to the input of the start check unit, and the transmitter is turned off.

 When working on the second (speech) channel (Y 1), the modulation input of the PRD is connected to the output of the mic-telephone amplifier (MU), and the low-frequency output of the PRM is connected to the input of the VLF telephone. Manipulating the state of the tangents (a 1, a 0) when removing the microtelephone (B 1) from the tube holder, they carry out voice communication in simplex mode. The indicated switching is performed by block 2 (Fig. 14), the basis of which is electronic keys 92.1-92.4, for example, K561KTZ, controlled by the input signal 4 (Y) and its inversion (Y) from the output of the HE 93 element.

The receiver 19 provides reception at the carrier frequency F _{3 of the} codogram (Fig. 15) of the transmitters of route sensors (MD) 1 in the near zone (20-30 m), which is due to the choice of frequency and power of the transmitter MD, sensitive receiver 19, the design of the receiving and transmitting antennas .

Accepted by the receiver 19 at the carrier frequency F ₃ , the MD codogram in its reception area is fed to the input of the second start check 3.2 block, the parameters of which correspond to the MD codogram format (Fig. 15) and are selected similarly to the parameters of block 3.1.

), то значения инверсных разрядов считывают с соответствующих инверсных выходов регистра, что позволяет получить значения (M_i,

). Одновременные разряды этой кодограммы поступают на компаратор и в случае равенства M_i

для, например, 0≅i ≅ > по сигналу окончания приема кодограммы происходит увеличение на единицу содержимого счетчика 49, за счет срабатывания элемента И 47, формирующего конъюнкцию QA BΛh. Иначе через элемент И 48, формирующий

A= B∧h происходит сброс счетчика 49.In this case, at the first output of block 3.2, a sequential code of the MD codogram is formed at the logical levels "0" and "1", at the second output, clock signals corresponding to the middle of the bit duration of the codogram, and at the third output, the strobe of the end of receiving the MD codogram. The serial code of the codogram is fed to the input of the sequential download of the shift register 42 of block 18. To the clock input of the shift of this register, clock pulses are supplied from the second output of block 3.2, which ensures loading of the codograms into the register. Since the number of the route sensor is represented by a paraphase code (M _i ,

), then the values of the inverse discharges are read from the corresponding inverse outputs of the register, which allows us to obtain the values (M _i ,

) The simultaneous bits of this codogram are fed to the comparator in the case of equality of M _i

for, for example, 0≅i ≅> by the signal of the end of the reception of the codogram, the content of the counter 49 increases by one, due to the operation of the And 47 element, which forms the conjunction QA BΛh. Otherwise, through the element And 48, forming

A = B∧h counter 49 is reset.

 If the vehicle is in the zone of reliable reception of MD codograms, then after receiving n codograms (for example, n 5), an enable signal will appear at the second input of the And 50 element and the strobe for receiving the codogram through the And 50 element will record the MD code in parallel register 45 and generate an output block signal for resetting to zero the counter of the traveled path and the counter of the divider.

 In the area of uncertain reception, failures in reception of codograms by paraphase cause a reset of counter 49 and, as a consequence, the prohibition of writing codograms to a parallel register. The choice of the output of the counter-decoder 49 sets the threshold for the circuit, taking into account the restrictions associated with the size of the zone, the speed of the vehicle, the length of the coding MD, its transmission speed.

 The MD code from the output of the parallel register 45 is entered into the USB SSD determination unit 11 to enable the SDM measurement mode in the area of the control section of the route and to the first group input of the second multiplexer for transmitting response code data (Fig. 8) in the vehicle location determination mode.

Block 7 sensor of the traveled distance and current speed is used in two modes. In the vehicle positioning mode, the sensor, together with the MD codogram reception unit, generates the current vehicle coordinate on the route. This information is the sum of the coordinates of the reference point of the last, passed vehicle, MD and the distance from the vehicle. Hence,
X _t X _onj + L _j where X _{t is the} current coordinate of the vehicle,
X _onj coordinate MD j on the route;
L _{j the} distance traveled by the vehicle from MD _i .

 In addition, in this mode, a rough analogue countdown of the current speed is formed to orient the driver of the vehicle in the road environment.

 In the mode of determining the specific resistance to movement, the unit generates a rough analog speed reference for acceleration of the vehicle by the driver in the control section of the route to a speed value exceeding the specified setting, and together with the determination unit for the differential speed generator forms a digital sample of the oscillation period of the output signal of the primary speed sensor of the traction ED at the beginning and the end of the reference segment of the path on the control section of the route when the vehicle is moving on coast.

The rotation of the rotor of the traction motor TED during the movement of the vehicle drives the rotor of the synchronous tachogenerator 51, mounted on a non-magnetic extension of the shaft of the TED (3, 4). The output signal of the primary sensor in logical units and zero, then Schmitt trigger 53 converts the input signal with a gentle edge and fall to an output signal with steep edge and fall, the latter is fed to a single-shot 54, which selects the pulse front, which triggers the RS-trigger, which allows the reading counter 57 K pulses of a stable frequency of the crystal oscillator 56, corresponding to the calibrated interval T _to τ _about (Fig. 4).

By connecting the R-input of the RS-flip-flop 53 with one of the Km outputs of the counter-decoder of the calibrated interval 57 and adjusting the value + E _{p, the} arrows of the speed indicator are aligned with the mark v _max at the corresponding start frequency of the RS-flip-flop 55 at the S-input. The duration of the interval is measured by the counter 60, to the incremental input of which the conjunction of the generator units 56 and the enable signal from the inverse output of the RS flip-flop 55 is supplied. At a vehicle speed not exceeding the specified v _o , the interval T _j ≥ T _o and the counter overflow signal 60 starts the second RS-flip-flop 65, prohibiting the measurement reading by logic zero at the 2 output of the block. If the measured speed v _j satisfies the relation v _max > v _j > v _o , then the value of T _{j is} read with the output of the counter 60, at the moment of the appearance of a strobe at 1 of the output of the counter 57. The measurement result is reset by resetting the counter of the measured interval 60 and RS-trigger 65 s K-1 counter output 57 before the start of the next measurement (Fig. 5).

If during the passage of a control section of length L _o (M) -trigger 55 will generate N _o calibrated pulses, then the price of each of them will be L _o / N _o δ _о m / pulse.

If it is necessary to count the distance traveled in discrete Δ1 lδ _{o, the} incremental input of the distance traveled counter is connected to the output of the counter-decoder 62, which after counting every l pulses of calibrated duration is set to zero, the contents of the distance traveled counter are increased by one. Counters 62 and 64 are set to zero by the signal of the MD codogram reception unit when the vehicle enters the zone of reliable reception of the next route sensor. The values L of the distance traveled in discrete Δ ₁ are formed at the outputs of the counter 64, which are the first group of outputs of the block.

Для исключения внутриоборотной ошибки первичного датчика блок 11 измеряет сумму T_ji за один оборот. Если, например, первичный датчик формирует 3 колебания на оборот вала, то блок 11 суммирует 3 следующих друг за другом T_ji, что позволяет определить в блоке 26 значение скорости

To eliminate the intra-rotational error of the primary sensor, the block 11 measures the sum T _ji per revolution. If, for example, the primary sensor generates 3 oscillations per revolution of the shaft, then block 11 summarizes 3 successive T _ji , which allows you to determine the speed value in block 26

=1) ) со скоростью v > v_o (

1), то по стробу с первого выхода счетчика-дешифратора калиброванного интервала α элемент И 34 сформирует сигнал β Z

. Так как счетчик 38 находится в нулевом состоянии, то уровень управляющего входа двухканального мультиплексора S 0 и

подается на инкрементный вход счетчика 37, Р выход (например, Р 3) которого соединяется мультиплексором 36 (

p) с инкрементным входом счетчика 38, логическая единица нулевого выхода которого разрешает прохождение сигналов β на тактовый вход регистра 31, который по фронту первого тактового импульса зафиксирует T_jiн+0, второй сигнал β зафиксирует Т_j1н+Т_j2н, третий Т_j1н+ Т_j2н + Т_j3н

T_jiн= Φ_м
Третий импульс β сбросит счетчик 37 по первому R-входу в ноль и переключит счетчик 38 в состояние 1, что закроет клапан И 39, обеспечив хранение

T_jiн в регистре 31 и вывод этих данных на первую группу выходов блока.According to this data, block 26 implements a branch of the vehicle location algorithm. If the vehicle moves along the measuring path of the RDM (Z 1) in coast mode ((

= 1)) with velocity v> v _o (

1), then on the gate from the first output of the counter-decoder of the calibrated interval α element And 34 will generate a signal β Z

. Since the counter 38 is in the zero state, the level of the control input of the two-channel multiplexer S 0 and

fed to the incremental input of the counter 37, P output (for example, P 3) which is connected by a multiplexer 36 (

p) with the incremental input of the counter 38, the logical unit of the zero output of which allows the passage of signals β to the clock input of the register 31, which along the front of the first clock pulse will fix T _{jin +} 0, the second signal β will fix T _j1n + T _j2n , the third T _j1n + T _j2n + T _j3n

T _jin = Φ _m
The third pulse β will reset the counter 37 at the first R-input to zero and switch the counter 38 to state 1, which will close the valve AND 39, providing storage

T _jin in register 31 and the output of this data to the first group of block outputs.

Further, the contents of the counter 38 will increase and when the internal state code corresponding to the reference l _et calls the logic unit at the i output, the valve And 40 opens to pass P (for example, three) clock signals for writing data to register 32. As a result, the second group of outputs of the block 11, the value Φ _k will appear, and the counter 38 will go into the state i + 1, connecting the incremental input of the counter 38 with q (for example, the 5th output of the counter 37, and the incremental input of the latter to the 5th input of the block, carrying information about turning on the equipment I transmit data to the CS. Thus multiplexers 12.1 12.3 connect the data register outputs Φ _n, Φ _k and measurement mode of the sensor 21 to respective inputs 13 coding CU block. After the q-times the measured data transmission gearbox counter 37 form the pulse increment for the counter 38, as a result of which the logical unit appears at the i + 2 output of the last one, returning the circuit to its initial state (counters 37, 38, registers 31, 32 are reset).

 The logical zero i + 1 of the output of the counter 38 (the output of block 11) will ensure that the multiplexers 12.1 12.3 switch to transmit vehicle location data.

 If the measurement conditions are violated (starting the AP, braking, movement speed inconsistency), the NAND 33 element returns the circuit to its original state, while the contents of the measurement registers are reset. If the measurement conditions are violated after counting the final speed, then resetting the circuit to its initial state is prohibited by the inhibit element 35 with i + 1 of the output of the counter 38.

 The reset ban is removed after q-fold transmission of measurement codograms.

 Multiple (q) data transmission with subsequent processing by block 26 according to majority logic algorithms increases the reliability of determining the DRC.

After starting the programs, the information processing unit 26 (microcomputer) performs a number of preparatory operations (1-8 blocks of the algorithm circuit). Then block 9 is a survey of the availability of equipment at the control point to the request mode of the i-th vehicle. The readiness flag is set by the coordination unit 24 at the second output. When B 1, the output of the information processing unit 26 receives information (N _i , Δ _i , G _i ). From the output of the coding unit 25, the tone signal of the frequency (phase) modulator comes to the input of the transceiver 22 of the first channel. At this time, the vehicle equipment, working in the mode of receiving information, determines the start signal and compares the number in the request codogram with its number. That vehicle, whose number coincides with the number sent by the control point, takes the codogram. The information received on the vehicle contains information about the deviation from the schedule and the command on board about the call to voice communication.

When the device is operating in the first cycle (k 1), the deviation and the call command will have zero values (Δ _i 0, G _i 0, i1), 2. η). In accordance with this, the arrow of the deviation indicator from the graph will be set to neutral position 0 and there will be no call to voice communication. After receiving the information, the equipment of the i-th vehicle is switched to the mode of transmitting information to the control point. At this time, the equipment at the control point is waiting for the flag of readiness to enter information into the memory of the microcomputer. After receiving information from the i-th vehicle from the outputs of the serial code converter 23 in parallel, the received information M _i k, L _i k, K _i k goes to the information processing unit 26. This information is sequentially processed according to the algorithm of the program, after which the next vehicle is interrogated. In the case of the arrival of information on the specific resistance to the movement of the vehicle from which this information was received, it is further requested four more times in a row. This is done to enable the implementation of a five-time bitwise majority logical processing of this information (blocks 15, 16, program algorithm diagrams). After calculating the specific resistance to the movement of the i-th vehicle, this value is entered in the graph of the executed movement of the i-th vehicle in the appropriate place for this information. According to the received information in subsequent cycles, the location of all vehicles on the route is determined and the specific resistance to the movement of each vehicle is recorded. The vehicle’s location from the schedules determines the planned time spent at a given point in the route (using the interpolation method for the given control points from the schedules). Then, if the position of the vehicle corresponds to the location of the control point, then t _{tech is} entered into the array of the formation of the executed movement of the ith vehicle (blocks 36, 37 of the algorithm diagram). According to the planned time and current, the deviation from the schedule of the i-th vehicle is determined and entered in the information output buffer for the i-vehicle in Δi. This information on board the i-TC is induced on the deviation indicator from the graph.

For voice communication between the dispatcher and the driver, the vehicle number is dialed on the keyboard of the microcomputer terminal. A keyboard interrupt is made and the program goes to the address of the keyboard interrupt routine. The subroutine determines the number in the cycle by the number of the vehicle, and the operation G _i 1 is performed. Having received this information, the vehicle equipment is activated in such a way that when the microphone tube 14 is inserted into the tube holder, the microphone telephone 91 of the control unit 9 will begin to emit an audio signal. When you pick up the tube 14, the audible alarm stops, and the two-channel transceiver 8 goes into the second channel. Voice communication with the dispatcher is through a single-channel transceiver 27 of the second channel. After the communication session, the driver inserts the handset 14 into the handset, and the dispatcher types the command reset symbol on the keyboard. When the initiator of the communication session is the driver, he sends a call command using the keyboard 20 to the vehicle. This information received at the control point will be converted into a command for the dispatcher on the display screen of the microcomputer. After which the dispatcher performs operations for the implementation of voice communication.

 To implement the graph of the executed movement of the i-th vehicle on the keyboard, you need to dial its number with the print symbol of the graph. The keyboard interrupt routine defines N TC and gives permission to interrupt from the ADC. The interrupt information processing subroutine from the ADCU outputs to the ADCU a graph of the executed movement. After the end of the output, interrupts from the ADC are prohibited and the equipment at the control point returns to its original state.
