The invention relates to automation and computer technology, specifically to means of monitoring the efficiency of use of vehicles in automated systems for recording and recording the working parameters of vehicles.

The purpose of the invention is to increase the reliability of recording information by eliminating mechanical connections and organizing and repeatedly reading data on the monitored operating parameters of a vehicle.

The drawing shows a functional diagram of the device for recording the operating parameters of the vehicle.

The device contains installed on the vehicle unit 1 transfer of working parameters and installed at the control point recorder 2, converter 3 codes, timer 4, block 5 information input, first counter 6, generator 7 pulses, switch 8, delay element 9, elements I and S 11, triggers 12 and 13, a decoder 14, a second counter 15, a shift register 16, a comparison block 17 of the initial setup block 18, a light emission receiving block 19.

The unit 1 for transmitting the operating parameters (total vehicle mileage, paid mileage, number of landings, fare collection amount, etc.) serves to receive and store information about these vehicle parameters, as well as to transfer this information to control point 2 in the form of a light code signal Block 1 mounted on a vehicle is made in the form of an electronic tactometer with a light-emitting element (radiator). In the proposed device, an electronic taximeter of the TAE-LK type can be used.

The recorder 2 is, for example, a teletype, which is intended to be punched on a paper tape and to simultaneously transmit information transmitted to it on a control tape.

The code converter 3 serves to convert the information received from the switch 8 into the necessary code and transmit it for subsequent registration to the recorder 2. As quality0

The transducer 3 can be used, for example, one of the units of the EC-1022 electronic computer, which is used to control the UVL-150-1 tape puncher.

Timer 4 is designed to change the time to the nearest second and is an electronic clock.

The information input unit 5 is intended to enter into the device information about the details of each driver (personnel number of the driver, number of convoy, etc.) and details. vehicle, and converting the entered information into the appropriate code. Information can be entered into the device from a numeric keypad, made, for example, by the type of keyboard of the Trell 003 telephone set-top box.

Counter 6 generates a specific sequence of codes that are intended to determine the sequence of processing information arriving at the switch 8 from blocks 4, 5 and 16. Counter 6 is a conventional 8-bit binary counter.

The generator 7 is used to generate pulses, which are necessary for the operation of timer 4, converter 3 of the code and the elements 10 and 11.

Using the switch 8, a certain sequence of information processing is simultaneously provided from blocks 4, 5 and 16. This sequence is determined by the alternation of codes at the second (control) input of the switch 8, which can be performed, for example, on an integrated circuit K155KP1s

The pulse delay element 9 serves to match the recording signals at the second input of the register 16 and the information signal at its first input in time.

Element AND 10 serves to transmit pulses from generator 7, arriving at its input, in the presence of enabling signals at other inputs.

Element 11 is intended to form the output signal, which is the write signal for shift register 16.

Trigger 12 is required to create an input enable signal.

element 11 after the arrival of the Start signal from block 1 and to create a inhibitory signal at this input after the signal End of block 1 arrives from block 1.

The trigger 13 serves to create permit signals at the inputs of the And elements when reading information from block 1 and to create an enable signal at the input of generator 7 after reading the information from block 1 and starting the process of registering the read information.

The decoder 14 is designed to provide at each of the outputs of the signal corresponding to the logical 1, only with a well-defined code of the input signal.

The counter 15 is designed to count the number of pulses fed to its input from an output of an AND 10 element, if there is a permitting signal at its other input and output this number as a binary code to the input of the decoder 140. Counter 15 is a four-bit totalizing count, CHICOM0

The shift register 16 is intended to record information about the operating parameters of the vehicle three times. The memory (width) of the shift register 16 is calculated so that it can accommodate all the information read three times from block 1, i.e. The memory of register 16 is conditionally divided into three sections.

Comparison unit 17 is designed to compare binary information recorded in register t6 sections with each other and to generate a logical 1 output at the output if the information supplied to the inputs of block 17 simultaneously from all outputs of register 16 and to generate a logical zero in case of a mismatch of this information coming from the outputs of the register 16 to the inputs of the block 17.

The initial setup unit 18 is designed to generate an enable signal at the corresponding input of the counter 15 and a zero signal at the other input of the same counter 15. The resolving signal is formed when there is a signal at the output of the receiving unit 19. A zero setting signal is generated with some delay.

on the falling edge of the signal taken from the output of block 19,

The light receiving unit 19 serves to receive the light signals from block 1, convert them to electrical signals and amplify these signals. It is a light-sensitive unit assembled according to a standard scheme.

In the device, a computer is also used as a registrar 2, and in block 5 for entering information, the details of the driver and the vehicle can be entered from a perforated or magnetic token,

The device works as follows.

In the initial state, the blocks located at the control point are connected to the power source (the power source and its connection with other blocks are not shown),

A vehicle (not shown) at the control point is missing and therefore there are also no light signals at the input of the receiving unit 19 and electrical signals at the outputs of the elements and blocks 9-11, 14, 15, 18 and 19.

Counters 6 and 15 are set to zero. Register 16 is recorded either randomly or read from the previous vehicle information, the output of the comparator 17 is a logical zero signal. Triggers 12 and 13 are in the zero state, i.e. on the direct outputs of these triggers 12 and 13 there is a logical zero signal. The first output of the generator 7 continuously receives pulses at the input of timer 4, from the output of which the time information arrives at the input of the switch 8o. The other output of the generator 7 removes pulses with a frequency of 1 kHz, which are fed to the input of the element And 10. Since the input of the generator 7 the enable signal from the direct output of the trigger 13 is absent, then there are no pulses at the corresponding output of the generator 7, i.e. There are no signals at the input of the converter 3 that do not allow recording to the recorder 2 and therefore no signals are generated at the outputs of the converter 3. Signals in the form of

the binary code from the information counter 6 is not removed, i.e. At the control input of switch 8, the enabling signals are missing and therefore the time information present at the other input of switch 8 is not recorded in the recorder 2, but is permanently present at this input of switch 8. At the other input of the last information from the output of block 5 no, since the details of the driver and the vehicle are not entered into it.

Before leaving the garage, the vehicle stops at the control point, the driver inserts a token in the information input unit 5, on which the driver and vehicle details are recorded, or types the same details on the keyboard. The information read from the token or from the keyboard goes to one of the inputs of the switch 8 and is present on it permanently until a corresponding enabling signal appears at the other input of the switch 8.

Then the driver brings unit 19 to the light-emitting element of unit 1.

The information recorded in block 1 is continuously emitted by the light-emitting element as if by a ring, i.e. information is given about total mileage, paid mileage, number of landings, amount of payment for travel, and so on, and then again about the total mileage, paid mileage, number of landings, amount of payment for travel, etc. Moreover, information is emitted from block 1 in a sequential code, i.e. sequentially, digit by digit, and limited to the Start and End signals, which are located respectively at the beginning and end of the array of information. Signals Start and End and informational 1 and O differ from one another in duration, for example, the duration of the Start signal is eight pulses, the End signal - five pulses, signal 1 - three pulses, signal O - one pulse.

If the reading of information from block 1 starts from the middle of the array of information, i.e. Immediately, information signals 1 and O start to arrive at block 19, and the Start signal is absent, then writing to register 16

the information read from block 1 is not carried out. When this happens the following.

A light signal, for example 1, from block 1 is received by the photosensitive element of block 19, which converts the light signal into electrical one and amplifies it. The electrical signal from the output of block 19 is fed to the inputs of the elements 10 and 11 and to the input of block 18, from the output of which a permission signal is applied to the corresponding input of counter 15.

On the other inputs of the elements And 10 and 11 there is a resolving signal of a logical unit, which comes from the inverse output of the trigger 13, which is in zero state. The trigger 12 is also in the zero state, i.e. at its direct output, and consequently, at one of the inputs of the element 11 there is a inhibitory signal of the logical zero.

One of the inputs of the element And 10 receives pulses from the corresponding output of the generator 7 pulses, which through the open element And 10 arrive at the counting input of the counter 15, which counts the number of pulses o Since the duration of the signal 1 is equal to three pulses, then the output of the counter 15 in The signal is in the form of a binary code 0011, 35, which is then fed to the input of the decoder 14, decrypting the code received on it.

After decoding, the signal of the logical unit appears at the corresponding output of the decoder 14, which is fed to the information input of the register 16. To write information information to the register 16, information 1 must be present at the information input of the register 16 and the recording signal at its other input. But, since the trigger 12 remains in the zero state, the And 11 element is closed and there is no signal at its output, and therefore, there is no signal at the corresponding input of the register 16, i.e. informational 1 is not written to it. Counter 15 is set to the zero state by a signal from block 18. Counter 15 is set to the zero state after each signal read from block 1 o

If, further, from block 1, signals O and 1 are received, then they are also not recorded in register 16, since trigger 12 remains in the zero state

After the arrival of the signal from block 1, it starts at the input of block 19, which converts the light signal into an electrical one and amplifies it. The electrical signal from the output of block 19 is fed to the inputs of the elements And 10 and 11 and to the input of block 18, from the output of which the enabling signal is taken to the corresponding input of the counter 15. On one of the inputs of the elements 10 and 11 there is a resolving signal of the logical unit from the trigger 130

The input element And 10 receives pulses from the output of the generator 7 pulses, which pass to the input of the counter 15, where the pulses are counted. Since the duration of the Beginning signal is eight pulses, the output of counter 15 is a signal in the form of a binary code 1000, which is then fed to the input of the decoder 14, decrypting the code received on it.

After decoding, a signal of a logical unit appears at the corresponding output of the decoder 14, which sets the trigger 12 to one. At the input of the And 11 element a resolving signal of a logical unit appears, but since the Start signal at the other input of the And 1 1 element is absent (finished), the signal at the output of the And 11 element, the output of the delay element 9 is absent and nothing at the input of the register 16 is recorded. The counter 15 is set to the zero state.

Then from block 1 to the input of block 19 receives an information signal (for example, 1), which then from the output of block 19 goes to the inputs of the elements Y o and 11, which open, and to the input of block 18, from the output of which the enabling signal is removed to the corresponding input counter 15. The pulses from the output of the generator 7 pulses through the open element And 10 are fed to the input of the counter 15, which counts these pulses. Since the duration of signal 1 is equal to three pulses, a binary signal appears at the output of counter 15

code 0011, which is fed to the input of the decoder 14.

After decryption, a logical 1 signal appears at the corresponding output of the decoder 14, which is fed to the input of register 16. At the other input of the last there is a recording signal passing through And 11 and delay element 9, and therefore for the first bit of the first section of register 16 it records 1. In all bits of the remaining sections of register 16, the pre- recorded information remains (5 previous information. Counter 15 is set to the cool state.

After writing 1 to the first bit of the first section of the register 16, from all the bits of each section of it, the information in the parallel code enters the comparison block 17, where the information recorded in the same bits of each section of the register 16 is compared.

Since the information recorded in sections of register 16 does not match, at the output of comparator unit 17 there is no signal of the logical unit, trigger 13 remains in the zero state.

Simultaneously, from the outputs of one of the sections of the register 16, the information recorded in this section enters the corresponding input of the switch 8, but since there are no signals from the generator 7 to enable recording at the second input of the converter 3, the information from the register 16 does not pass through the switch 8 and the converter 3 codes and in the recorder 2 is not fixed.

Then, the next information signal (for example, O) is fed to the input of block 19, which is fed to the inputs of elements 10 and 11, which open, and to the input of block 18, from which output a resolving signal is fed to the corresponding input of counter 15. The generator pulses 7 to another input of counter 15. Since the duration of the signal O is equal to one pulse, the output of counter 15 is a signal in the form of a binary code 0001, which is then fed to the input of the decoder 14.

After decoding, a logical zero signal appears at the corresponding output of the decoder 14, which is fed to the input of register 16. For 30

writing to the last information signal O requires the presence of a logical zero signal at the information input of register 16 and a recording signal at its other input. Since the signals are present at these inputs of the register 16, the unit recorded in the first bit of the first section of the register 16 is shifted by one bit, and in the first bit of the first section O is written. Counter 15 is set to the zero state.

Next, in block 17, the information recorded in the three sections of register 16 is compared with each other, and since it does not coincide, the signal of the logical unit does not appear at the output of the comparison block 17, the trigger 13 remains in the zero state, allowing signals on the corresponding input of the converter 3 of the code from the output of the generator 7 is missing, and information from the register 16 to the recorder 2 is not received and is not recorded

Then to the input of block 19 receives the next information signal (O or 1), and the processing of this signal is similar.

After the last information signal arrives from block 1 and after it has been processed, all bits of the first section of register 16 are filled with information read from block 1, and the second and third sections of register 16 record the previous information, and therefore as a result of comparing information over all sections of the register 16 at the output of block 17 the signal of the logical unit does not appear and the trigger 13 remains in the zero state

At the end of the array of information from block 1, the signal ends at the input of block 19, which then goes to the inputs of elements 10 and 11, which open, and to the input of block 18, the output of which is transmitted to the corresponding input of counter 15 (enabling signal). At the output of And 11, a signal appears, which is fed to the input of the delay element 9. The pulses from the output of the generator 7 through the open element And 10 arrive at another input of the counter 15, which counts these pulses. Since the duration of the End signal is equal to five pulses, the output of the counter 15 appears

a signal in the form of a binary code 0101, which is then fed to the input of the decoder 14. After decryption, a signal of a logical unit appears at the corresponding output of the decoder 14, setting trigger 12 to the zero state. At the other output of the decoder 14 and, therefore, at the corresponding input of the register 16 there is a logical zero signal, and at the other input of the register 16 there is a write signal from the output of the delay element 9, and therefore the information recorded in the first section of the register 16 is shifted by one bit. .

The counter 15 is set to the zero state.

As a result of comparing information on all sections of register 16 at the output of block 17, the signal of the logical unit does not appear and the trigger 13 remains in the zero state. At the corresponding input of the converter 3 of the code, the enabling signals are missing and information from the register

16 in the recorder 2 is not fixed. Then the second cycle of receiving information from block 1 begins, i.e. first, the Start signal comes, which translates trigger 12 into a single state, then information signals and the End signal, which translates trigger 12 into a zero state. As a result of receiving and processing information from block 1, this information is recorded in the first

and the second section of register 16, and in the third section of this register 16, the previous information remains recorded, and therefore, after comparing the information recorded in all three sections of register 16, the output of the block

17, the signal of the logical unit does not appear, the trigger 13 remains in the zero state, information from register 16 in the recorder

2 is not fixed.

After that, the third cycle of receiving information from block 1 begins, i.e. the Start signal comes first, which sets the trigger 12 to the one state, then the information signals and the End signal, which sets the trigger 12 to the zero state. As a result of receiving and processing information from block 1 in register 16,

by shifting the information already recorded in it, the information is recorded in all three sections of register 16.

If, as a result of comparing the information recorded in all sections of register 16, at the output of the block (7 a comparison signal equal to a logical unit does not appear, indicating a discrepancy in the information recorded in sections 16 of register 16, the next, fourth cycle begins receiving information from block 1, processing this information; writing it to register 16 by shifting the information already recorded in it and comparing it to each other in comparison block 17. This continues until the information recorded in register 16 sections does not match. uh In addition, a logical unit signal appears at the output of the comparison bank 17, which sets the trigger 13 to one.

An indicator (not shown) signals the end of reading information from block 1, and the driver removes block 19 from the light-emitting element of block 1.

Then begins the process of recording information on the recorder 2 as follows.

After the trigger 13 is set to one, a prohibitory signal appears at the corresponding inputs of the elements AND 10 and 11, they are closed and the information from block 1 does not pass through them. At the direct output of the flip-flop 13 there is a signal of a logical unit, which is a permitting signal at the input of the generator 7, which begins to generate pulses at its corresponding output, which are fed to the input of the inverter 3 codes.

When a resolution signal appears at one of the inputs of the counter 6 from the direct output of the trigger 13, and at the information input of the counter 6 pulses from the output of the converter 3 of the code from the information output of the counter 6, the control input is sent to the control input of the switch 8 information simultaneously arriving at the switch 8 from blocks 4, 5 and 16 in the form of a binary code.

the information output of counter 6 is an 8-bit binary counter output. This counter 6 changes the state at the output of each pulse coming from the corresponding output of the converter 3 of the code, therefore at this output of the counter 6 you can get 256 different combinations, which are eight-bit binary code.

In accordance with the first state on the information output of the counter 6, i.e. In accordance with the first shoe supplied to the control input of the switch 8, the latter passes the first digit of the information coming from the information input unit 5 to the corresponding input of the converter 3 of the code. The latter forms this digit, which arrived at its input in the form of a binary code, into the code of the registrar 2 and transmits it to its input. The recorder 2 punctures the first digit of information in a code convenient for entering it into a computer on a paper tape, and simultaneously prints it on a control tape.

Upon completion of processing by the converter 3 of the first digit of information from block 5 and transmitting it to recorder 2 for recording from the output of converter 3, a pulse is input to the corresponding input of counter 6, changing the state of counter 6, as a result of which the code at its first output also changes.

In accordance with the code that has changed, the switch 8 passes the second digit of information from block 5 to the input of converter 3, which converts it to the code of registrar 2 and transmits to the last one. Upon completion of processing by the converter 3 of the second digit of information from block 5 and transmitting it to recorder 2 to register from the output of converter 3, a counting signal is sent to the counting input of counter 6, which changes the code at its information output.

Further processing of the third and subsequent digits of information from block 5 is similar.

This is repeated until all the digits of the information from block 5 are processed in converter 3 and registered with registrar 2.

After that, in accordance with the code on the information output of counter 6, which arrived at the control input of switch 8, the latter begins to receive information from timer 4 sequentially, digit by digit (first, second, etc.) in accordance with the code present on the information the output of counter 6, and, consequently, at the control input of the switch 8. Further processing and recording the digits of the array of information received by the communication parameters of the next vehicle.

The use of a device for recording vehicle operating parameters will improve the reliability of information received from a vehicle on its operating parameters.
