Abstract

The invention relates to devices for controlling the movement of vehicles and can be used in the systems of accounting and operational management of transport. The aim of the invention is to improve the speed of the device. After switching on the device, the transmitter generates a continuous carrier signal. In this case, the signal from the second output of the receiver 26 of the moving object (SW) starts the transmitter 27. The code of the random number generator 35 is rewritten into the register 34 and, after being transmitted by the transmitter 27, the sync pulse is transmitted bit by bit to the control. The transmitted code is unitary and the queue number of the software for allowed codes is meaningful. The decoder 16 located on the CP records the positions in the queue that are occupied by only one software. In this case, transmitter 2 emits signals indicating the allowed positions in the queue, i.e., positions occupied by only one software. If the software has selected the 5th queue for codes, the counter 36 records the code that encodes the message of this software. If the software selects the allowed queue, the code from the counter 36 is rewritten into the coding block 38 simultaneously with the software loading information from the output of the sensor 39. Then the encoded message through the OR 42 element and the receiver enters the CS. 4 il.

In order to uniquely determine the sum message of the addendum messages (i.e., messages transmitted from each moving object), the system of single-digit decodi codes is not used. Messages transmitted from moving objects are encoded with codes possessing such a property that the sums of different combinations of the terms (i.e., the total messages

nn) are different from each other (table)

Each mobile object selects some code from the list of codes to encode its message.

Dp definitions of messages transmitted from moving objects using an algorithm built on analysis; correct vectors.

If the difference between the two code vectors of the i-ro code x; and at; , then we obtain the difference vector dj-x; -y ;, which fully characterizes the i – n code. Then the codes given can be written as a matrix of difference vectors:

If all moving objects transmit a logical zero, then the receiver I receives the total message

When looOn is different to the co-emania, the addends to messages are received with a cumulative consensus

The difference between the total Z obtained and the fixed X is called a syndrome. S-Z-X syndrome analysis allows decoding of the resulting vector. Syndrome S can be represented as

If the number of moving objects T is less than eight, then decoding is performed taking into account that T moving codes use T first codes in transmission. For this, the sum of logical zeros T of the first moves is not used as a fixed sum for decod.

For example, with such a sum would be - X-X, ... + Xj-0222.

In each moving object, located in the control eems, the request signal received by receiver 26 passes through selector 28 of frequency f, writing to the register 34 a shift code contained in the random number generator 35. An eight-bit binary number a (a, ... ag) is written to the shift register .44, having one single unit in any of the bits indicating the position occupied by the mobile object in the code queue. The request signal from the output of the selector 28 is fed to the inputs of the drivers 30 and 31 pulses. Shaper 30 pulses generates a clock pulse (SI) with a duration of €. The sync pulse is inverted by the element HE 32 and, upon entering the input element I 46, prohibits the passage of clock pulses from the generator 37 clock pulses to the shift register 34. During the time C, the transmitter 27 is transmitted to the clock by a clock pulse received at its input through the element OR 42. After time C and the element E 46 opens, the clock pulses come and the input of the shift register 34 and the bit eight, recorded in register 34, younger the forward discharge comes through the element OR 42 to the transmitter 27. Thus, the transmitter 27, having transmitted a sync pulse, starts transmitting the binary number a-Ca, ..., a,), indicating a busy queue 430, dl. which will take time equal to C (Fig. 46). Therefore, during this time, the prohibitive signal generated by shaper 31 and the inverting element HE 33 is applied to the input of element I 45.

At the control point, with the arrival of a clock pulse, received by antenna of receiver I and tuned by a selector of 14 clock pulses, a puller of 15 pulses is triggered. After each mobile object, after a synchro impulse, the cers dwells an eight-bit binary number, a bit, and an angry position with a given moving object c. queues for codes. Per device kit

If a; -1, then the i-position in the queue is occupied by a single moving object. If, then the i-position in the queue is behind several moving objects. Signals received by receiver 1 are converted into digital form by analogue to digital converter 3 and fed to inputs of decoder 16. At output of decoder 16, the signal appears only if a; "1. Thus, the decoder 16 selects those positions in the queue that are occupied by a single moving object.

(

With the advent of the sihihroimpulsa shaper I5 forms a pulse of duration (Fig.46). During this time, the receiver I accepts eight bits of the number a- (51a ,, 51a j, ... .., a.). The signal generated by shaper 15 is fed to the input of element 22, and simultaneously the second input of this element receives signals from you :: decoder 16, and the third input is frequency 2 generated by generator 18. At the output of element 22, it forms B1 than the serial code, the eight-digit number L- (b ,, b, ..., bg, the units of which are filled with the frequency f, and if Sa; -. The sigmal from the output of the AND 22 element goes through the OR 25 element to the transmitter 2. Thus , as it is received, ..), transmitter 2 emits a binary eight-bit broadcast - (b4, b ,, ..., b) indicating the allowed positions in the queue for codes (Chro) (fig.4a). At the same time, the counter 50, block 4 of the analysis counts the number of positions selected by a single single movement by JM oSehtom. The signal formed by the shaper 1 5 of duration d is inverted by the element NOT 23 and, by entering the fourth input of the analysis unit 4, prohibits the analysis of signals arriving at this time at the inputs of the analysis unit 4. At the same time, the signal from you (the element NOT 23, arriving at the input of the element AND 20, locks it for a while, thereby preventing the formation of request signals. If there is no one in the queue for codes selected by one (

uniform by: x object, th after expiration. iiit C element AND 20 opens and resumes the generation of request signals (Fig. dd). If there are 3 queues for codes, the position is occupied by one moving object, then the signal from the V-channel of the decoder 16 sets. trigger 24 to zero state. The generator 19, controlling the trigger 24, stops the generation of request signals until the trigger 24 is reset to one state.

On a mobile object, simultaneously with the transfer of a binary eight-bit number a- (a, ..., hell) (430), an receiver 26 receives an eight-bit binary number b (b4, b, ... .. ,, bj) (ChRO ) transmitted from the control point. The received signals pass through the selector 29 and the H.1 input of the code selection counter 36 and h.i the second input of the AND element 43, the first input of which receives the signal from the output of the shift register 34, arrive. If not a single I) g: single objects, nachsd - Shch.1KSHA in the control zone, did not choose the same as this moving object, potitsii in the queue nz codes, then H.1 PSRP and BTOpov element I And 43 moves simultaneously signals 1P p M of August 34 sdniga and selector 28 i.,. .i; i with the output of the element And 43 set.) nlnE), 1 - G trster 41 and one state. The signal of the single output of the trigger 41 gives a fragmentation to the inputs of the switches 44 and 43, and the signal from zero OKF 1 stops the counter 36 of the pyr code. Subsequent signals, every second, the second input of the counter 36 and the selection of the code, are not counted. If an object is picked up; 1l Ku of no 3HUHW in the ocher; and1 on codes, then by the time the istet of the code selector counter 3h and it is recorded, the number of occupied items located in the code queue from the first position to K th The JTO number corresponds to the code number with which the message of this podfied object is encoded. With this choice of code, T moving objects are used when transmitting T first codes, this condition is necessary for decoding using the list of all possible summary messages.

After the time interval Tj, after receiving the request signal by the receiver 26, the element I 45 is open: 1, provided

that the position in the queue for the codes selected by the mobile object is allowed and the trigger 41 is set to one. The clock pulses from the output of the clock generator 37 through the open element I 45 are fed to the inputs of the coding unit 3, after which it begins to encode the message with a code, the number of which is given by the output of the code selection counter 36. In the proposed device, the message carries information about the number of the movable object and the presence of cargo on board the movable object. Information about the loading of a moving object in the coding unit 38 comes from the loading sensor 39 in binary form, namely 1 - a moving object with a load; O is a moving empty object. The coded message from the output of the coding unit enters through the element OR 42 to the transmitter 27 and is radiated by its antenna to the air. At the control punch in block 4, the received summary message is decoded using an algorithm built on the analysis of difference vectors. In decoding, the entire summary message is divided into blocks of four bits and analyzed each block. Having completed the decoding of each block from the summary message, analysis block 4 abatnaet the signal that is fed to the input of memory block 8. This signal in the memory block 8 records the bits obtained as a result of the decoding. Then, the analysis unit 4 proceeds to the analysis of the next four bits of the total message, etc. until the end of the message. If during the decoding of a block from the summary message, the received number; 1O of the transmitted logical units does not correspond to the number at the outputs of the adder 52 and the subtraction element 47, then at the second output of the analysis block 4 a signal is generated, which through the one-shot, op 6 arrives at the counter 7 and through the element 12 on the first input of the block 13 of the request. Another input element AND 12 is connected through the element OR 10 with the outputs of the counter 7. In this case, in block 13 of the request, a re-transmission signal (PI) is generated as follows: the unidentified signal arrives at the first input of the element 21, the second input of which receives the frequency fj .. Signal Filled

the frequency from the output of the element 21 through the element OR 25 enters the transmitter antenna 2n efr (fig, 4e, e On mobile objects transmitting the message, the retransmission signal received by the receiver 26 passes through the selector 29 of the frequency fj and, having entered the input coding unit 33, translates it to the initial state. Then coding unit J8 re-starts the message transmission. The number n of the retransmission signals is determined depending on the intensity of interference in the air, the reliability requirements of the registration and the volume is determined by the counter a 7. If the correct reception message did not happen as a result of the Pontrols, counter 7 overflows and the unrecognized signal goes through AND II and OR 9 to the sixth input of the request block 13. With this signal, the trigger 24 is set to one and the request unit 13 resumes the request signal formations. In the event that the entire summary message was received without any work, i.e. all the transmitted messages were determined and sent to memory block 8, then on the first output block of the 4 ingress program, sigch identification and who leperj odnonibrlto; 5 steps D is a reset circuit of the counter 7, cut the element rtili Y and nl of the sixth nxo; i block 13 For this-. 1: Ig and 1Lu trigger 24 again uslnoliplotts in a single state and b;: Approx. 13 tlg grew to form a sig H.ui sigled, filled with a frequency f which is indicated by the substitution of otiazivan; UIH of those IIO ;; HH : “) IUX objects that sent messages, and a request signal; q; 1n those that; 1nbo still} je moths, or entered but were denied use of the code they mentioned.

At the control point, the signal formed by the single vibrator b is also fed to the output of the device. By this signal, messages recorded in memory block 8 are transmitted to external display devices, such as a display.

If there is a resolution at the fourth input of the analysis unit, the clock pulse generator generates clock pulses. Each pa: 4pd total is calculated in a digital code is fed to the first three inputs of the subtraction circuit as the bit of the first operand.

then, after four clocks, the result of subtraction 2 — X-4433-0232-4201 — will be written to the shift register 49, where the subtraction is performed.

Adders 52 and 52 perform a total of 42 01-43. The summation result obtained at the output of the adder 52 is equal to 4, i.e. at the first output of the adder 52, a logical zero is received, therefore, a zero is transmitted to the seventh gsd object. The summation result obtained at the output of the adder 52i is equal to 3, which means that in the first discharge of the adder the semi13

chen i, which means that the eighth moving object transmitted 1,

On the circuit of adder 52, as operands, the higher bits of outputs of adders 52 and 52 are received. As a result, the output of adders 52j will be a number, i.e. the first and third moving objects passed a logical one.

Element 47, the subtraction subtracts the same operands: 2-1-), which means the first bit of the result of the subtraction in the binary representation is zero, hence the second: the user transmitted a logical zero. Elements 47 and 47 of the subtraction are subtracted 42-01 41. The result of the subtraction obtained at the output of the element 47 of the subtraction is 4, therefore, the adder 52, and the element 47 Ouchntani as the first operand receives the number 2. The result of the subtraction obtained at the output of the element 47 "Subtraction is equal, therefore the number 0 is fed to the adder 52-} and the subtraction element 4/4 as the second operand. the fourth moving object was transmitted by G and the sixth - O.
