As an example of a specific embodiment of the device in FIG. 2-8 are functional diagrams of the main components of the proposed device and a brief description of their operation and interrelations with each other (test reports of the main components are attached). Using the remote control 1, the dispatcher of the station introduces information into the device (Fig. 1): list of work according to the monthly and annual schedules of the current content of the device; the content of operational daily and monthly events; location of vehicles distance.

Dispatcher 1 (Fig. 2) is a unified device for address recruitment and value of various types of information entered and displayed in block 5, connected to block 7 and inputs of coding block 14, from where each message enters register 16 of records. The information contained in register 16 is monitored by the display unit 17 (indicator IV-18 lamp), and transmitted to register-to-receiver-register 2 by the transmitter 18. In this case, time division of signals is used with sending synchronizing pulses.

The outputs of transmitter 18 of console 1 are perceived (FIG. 3) by the receive receive shift register 19 of receiver 1 associated with register fill control element 21, the output of which controls the clock element 20 transmitting clock pulses to receive register 19. Using register fill 21 allows you to send and receive words of various lengths. Element 22 transfers the receive register 19 to the initial (zero) state after receiving and translating the recorded information.

The outputs (1 ..., P-1, p) of the triggers of certain bits of the receive register of the receiver 2 are connected to the inputs of the converter 3 (Fig. 4), designed to decrypt, store and display alphanumeric information about the content of operational daily and monthly servicing the signaling system devices, the plan and location of the vehicle distance, as well as the translation of quantitative messages in the decimator 4 with automatic reference settings.

Converter 3 contains elements 24, whose inputs are associated with the outputs defined (1 ..., P-1) bits of the register of receiver 2 (9) and element 23, the input of which receives the coded value of the address of the recording block from the last P bit this register. Moreover, the recording of the content of the alphanumeric message is made to the register 26 of the recording of the display unit 32 in the presence of a permitting signal from the element 23 and the decoder 25 decoding the P-1 and P-2 message bits. Identical display units 32 are built using the principle of dynamic indication, in which the switch 27 controlled by the generator 29 polls the register register 26 bits in turn, connecting a code converter 28 to its outputs. The signals from the latter are sent to the anodes, the indicator 31. Turning on the corresponding bits the lamps are produced by signals from the distributor 30, which by means of the generator 29 is synchronized with the switch 27.

The decoder 4 (Fig. 5) is designed to convert the quantitative parameter code received from the converter 3 and block 10 into a control effect on automatic reference settings, with the help of which, on certain zones of block 5, the list of works on the monthly and annual technical schedules device content, as well as reference information is needed with an indication of "tips and tricks when

On finding and troubleshooting failing devices of automation and remote control.

The address part of the message coming from the output of the corresponding element 24 of the converter 3 is fed to the input of the element 33, associated with the element; 34, to certain inputs of which the information part of the message comes from the converter 3 and the block 10. From the corresponding outputs of identical amplifiers 35, to

0 inputs which are affected by signals from the outputs of element 34, control commands for the buses Week and Day arrive at the corresponding inputs of the relay block of the first automatic reference installation for setting the list of jobs for that day, through the buses Quarter and Month to the corresponding inputs the relay unit of the third ASU-3 to display the necessary reference information with an indication of "tips on rational methods

0 finding and eliminating various malfunctions of controlled signaling devices. Moreover, the above relay blocks are placed in block 5.

The display control unit 6 serves to receive information 5 coming from the reading element of the block 9, and to transmit it to the symbol indication unit, where it is displayed on the screen of the cathode ray tube. Automatic reading and recording of data from the display screen

0 printing is carried out through the control unit 6 having a standard interface with the printing unit 8.

For automatic fixation and transmission to block 6 of managing data on the numbers of failed objects controlled by the well-known telemetry control system, the nature of the malfunctions, as well as the duration of the elimination of failures, time block 9 was assigned (Fig. 6). Block 9 contains elements of time, generating code combinations in accordance with the value of the current time, a distributor cyclically checking elements of monitoring the status of triggers of the diagnostic information receivers, elements of reading that provide data on the numbers of failed objects, the nature and time of elimination of input failures. block 6.

When diagnostic information is received by the selector 11, the corresponding element 36 of the control of the state of informational triggers gives a short-term pulse, putting the trigger 37 into a single state. The cyclically operated valve 38, connected via the bus "Synchronization with the valve of the block 10, polls the outputs of the flip-flops 37 in turn. The appearance of a single signal at the output of the flip-flop 37 will block the distributor 38, which actuates the read element 40, the inputs of which are connected to the outputs of the element 39 by the outputs of the distributor 38, which carry information about the number of the failed object, as well as to the communities. “The nature of the failure by the outputs of the decoder of block 10, which determines the nature of the malfunction (the number of the missing rmatsionnogo pulse).

Thus, data from the time of the occurrence of the malfunction, the number of the failed object and the nature of the malfunction is received from the output of the readout element 40 to the input of the control unit 6. After this information is recorded in the control block 6 by subsequently displaying the display from the control block 6 on the corresponding line of the bus, the Acknowledgment goes briefly to another installation input of the trigger 37 pulse, translates it to the zero state, which causes the dispenser 38 to unlock. elimination of failure on a previously faulty object again triggers trigger 37 from the circuit 36 for monitoring the status of information triggers of the selector 11 receivers to a single position.

This results in writing the current time value to the line of the display screen assigned to this object. Restoration of the object, i.e., the absence of information from the block 10 at the corresponding inputs is perceived by control block 6 as a signal to read data about the time of the failure, the number of the malfunctioning object, the nature of the failure and the time the screen was restored to the object print unit 8, which is associated with control unit 6. On the bus "Acknowledgment circuit comes to its original state.

The second group 13 KP technological data, installed in distance workshops and consisting (Fig. 7) of the pulse generator 41, which converts a sinusoidal voltage 50, is intended to transmit technological information on the progress of the daily and monthly planned and operational measures for maintaining the signaling devices. Hz into rectangular pulses, and a distributor 42, which is connected via a block of 43 buttons to a generator 44 of the tonal frequency. Block 43 includes four groups of buttons. The first group of buttons (Ki, ..., Kp). serves

for transferring data on the progress of work on the monthly schedule of the current content of the signaling systems, the second group (Ki, ... Kr) - according to the annual schedule and a third and fourth group, respectively (Ki, ..., KK) and KI, ..., Kf) - on the implementation of operational (unscheduled) daily and monthly activities.

Since all distance shops operate according to a single schedule, each 44 tone frequency generator sends as many information pulses to the selector in the series as information pulses, as during the given period, the workshops carry out technical maintenance of signaling devices.

For translation with subsequent display in block 5 and automatic registration of information on the progress of daily and monthly planning and operational measures for servicing signaling devices in the distance shops

block 7 is intended (fig. 8). Connected with the binary indicators of the block 5, the outputs of the display triggers of all the receivers of the second group KP 11 are connected to the distributor 47, the control input of which is connected to the output of the counter 46, the clock

the input of which, in turn, is connected to the output of the generator 45. Upon receipt from the keyboard of the manipulator 1 via the bus, a signal is printed to the enabling input of the counter 46, the latter actuates the distributor 47, the output of which is connected to the input of the decoder 48 associated with the inputs of block 8 of the print.

The fixation in unit 8 of the printing of a single state of the triggers of the indication of the selector AND of the technological data signals indicates that the workshops carry out the corresponding technological measures.

The use of signaling and communication distances in the proposed device allows for the automation of collecting, storing and documenting large volumes of operational and technological information and the timely submission of diagnostic data with an indication of "tips on rational methods for finding and troubleshooting the signaling device
