Description

The invention relates to telemechanics and is intended to automate timekeeping.

A device for collecting and transmitting information on the main bus is known. St. No. 294163, containing, at a controlled point, a line connection unit, a matching scheme for receiving telemetry commands and a matching scheme for transmitting information signals and sync pulses, and a central register — a cyclic register, a cyclic register stop trigger, an information signal transmission priority block and a control unit registers of information.

Such a device is characterized by the impossibility of using it for automation of timekeeping.

The proposed device differs from what is known in that at a monitored station a token pressing control circuit and a token slot control unit and a signal conditioner are introduced, both of the aisle sensors connected to the turnstile closing control circuit, one output of the blocking trigger is connected to one circuit input signaling and to the second inputs of both coincidence circuits, the second output of the lockout trigger is connected to the control circuit of the gate slot for the token and to the second input

alarm circuits, the first input of the blocking trigger through the signal conditioner is connected to the first input of the time relay to one of the passage sensors, and through the circuit

decoupling — to the token emission control circuit, which is connected to one of the aisle sensors, another interlock trigger input is connected via a time relay to the token emission control circuit and to one of the triggers, the token pressing control circuit is connected to the link disconnection control trigger.

FIG. 1 shows a block diagram of the proposed device for collecting and transmitting information; in fig. 2 is a block diagram of an automated pass; in fig. 3 is a block diagram of a controlled item.

The device for collecting and transmitting information contains the central point 1 and the controlled points 2i-2n. On each automated checkpoint, two controlled points are established: one for accounting at the entrance, the other at the exit.

All controlled points are connected to the central point by one common cable line.

Every first controlled point to receive from the central point cyclically

The polling command has one individual wire 3 ,, i.e. when connecting a controlled points for a cyclically polling command in the cable must be

П wires (from 3i to Згг) All other wires are switched. Wires from 4 to 45 are used to transmit the following service commands:

"Connection confirmation (wire 4i); “Received (wire 42); “Error (wire 4z);

“Continued transmission of information (wire 44);

(wire 45 serves to transmit a sync pulse).

Wires from 5i to 5t are used to transfer information. code. The number of these wires depends on the type of code transmitted information.

Automated aisle (Fig. 2), in addition to the two controlled items 2i and 22, contains sensors for passage 6 and 7; automatic closing turnstile 8.

A passage of this type simultaneously produces people only in one direction.

Depending on the direction of movement, a controlled item 2i or 22 is turned on. Upon entering the slot of a controlled item 2i A token is inserted. After reading and transmitting information to the central point, the token is released and, upon the pad, delayed by the gate. If the information was transmitted correctly, the chains closing the turnstile are blocked and the passage is free.

When the sensor passes pass 7, the token is put into a pocket with free access, from where it is then removed by the pass.

If after a certain time the passage is not completed, the token falls into a pocket with restricted access, from which it is removed only by service personnel. This reveals noted people, but not forgiving through the checkpoint, i.e., fictitious passage is excluded.

When you turn on the controlled item 22, the navigation will work on the way out and will not let people in the opposite direction.

20 for transmitting potential levels carrying information.

The device works as follows. When starting the central point 1, a cyclic interrogation command is formed 25 Yes for the controlled points 2i-2. Cyclic polling continues until a monitored item 2, - that is ready for transmission and is detected, on which trigger 11 (Fig. 3) is turned on, which forms a comaid,

0 requesting connection.

The insertion of a token closes the block contact of the token 9 and delivers a potential level of voltage to the driver 10. From the leading edge of this potential level, the driver 10 generates a pulse that triggers trigger I.

The potential level from one trigger output 11 is fed to the control circuit.

0 by pressing the token 12. The circuit is started and presses the token for the time of reading and transmission of information. The potential level from the other output of the trigger 11 is applied to one input of the coincidence circuit 13. To its other

The 5th entrance from the central point 1 comes in a cyclically clearing command. The coincidence circuit 13 is triggered and the output signal is fed to the link connecting unit 14. From the leading edge of this signal, the triggers 16 and 17 are switched to the initial position, from which the potential level of the corresponding polarity is removed and fed to the input of the connection unit 14. In this case,

5, a command is generated from the leading edge of the shaper 15 and the command "Connection confirmation" is generated, which is transmitted to the central point 1 via the communication line (Fig. 1). At the central point after receiving

0 of the "Confirm connection" command, the cyclic interrogation of the monitored points 2i-2 "is terminated, and a potential level is output via the Cg wire, thereby pushing the cyclically polling command to all

information transfer time.

The potential level, taken from the output of the connection unit 14 at the controlled point 2i, opens the remaining channels 42-45, 5 - These communication lines built on the coincidence circuits 18, 19, 28, 39, 41i-41g (Fig. 3).

At the central point 1, after receiving the command "Confirm connection", information is read from specially built-in time records for hours and outputted to punched tape and computers. At the same time, the command "Continued transmission of information" is formed, which by wire 4 goes to the controlled point 2, passes the coincidence circuit 28 (-see Fig. 3) and returns to its initial position the trigger 38, which forms the potential level of the sync pulse, and the triggers , forming potential levels that carry information, and the falling edge starts the circuit 33, which controls the reading of the transmitted information.

The read information from the first bit of the imager 32 numbers of the monitored is fed to the encoder 37 and, depending on the type of the encoder, can be recorded in different codes.

The code pulses of the encoder 37 trigger the trigger 38, which forms the potential level of the sync pulse, and the 40i-40m triggers, from the outputs of which potential potential levels are removed, and through the coincidence circuits 411-41t, the communication lines 5i-5m arrive at the central point 1. Potential level the sync pulse is removed from the flip-flop 38 and through the coincidence circuit 39 and the wire 45 is fed to central point 1, which outputs this information to punched tape and computer.

When the reading and transmission of information from the imaging unit 32 is completed, a new command comes from central point 1: Continuing the transmission of information and the information should be read from the imaging instrument 34 corresponding to the passage of the “Arrival or Exit” code. Next, information is read from the token 35.

After the last bit has been read from the token 35 by shaper 36, a signal is generated, which passes through a tweeter 37 and is transmitted to a central point in the "End of Information Transfer" code, where it is converted into a service code for punched tape and for a computer.

When a response is received from a tape punch and from a computer at the central point, the command “Receive. This command, via the wire of the communication line 42, arrives at the monitored point 2, passes through the coincidence circuit 18, switches the triggers 16 and 23, and starts the time relay 27. The potential level that opens the communication line connecting unit 14 is removed. Block 14

closes and closes communication channels with its output voltage level (coincidence circuits 18, 19, 28, 39, 41i-41 ™) From the leading edge of the potential level removed from trigger 16, trigger 11 is brought to its initial position, and the command requesting y, is over.

After disconnecting the controlled item

2i center point 1 continues again

cyclical survey of controlled items.

During the transition trigger 11 to the original

position off control circuit 12

pressing a token. The token is released and,

the pad is delayed by the flap in

the beginning of the journey.

The potential level, taken from one output of lockout trigger 23, turns off the signaling circuit 22 and closes the matching circuits 30 and 31 of pass sensors 7 and 6, and the potential level taken from the other trigger output, turns on the circuit 22 and the damper control circuit 20 covering the insertion gap counters at the time of passage through the automatically closing turnstile 8 (Fig. 2).

When passing the sensor 7, which is on the other side of the turnstile 8, the sensor 7 generates a signal confirming the passage. This signal turns off the time relay 27 (Fig. 3) and starts the token ejection control circuit 25. The gate blocking the token path rises and the token falls into a pocket with free access,

where it comes from passing.

From the trailing edge of the signal confirming the passage of the driver 26, a pulse is formed with a delay, which turns off the blocking trigger 23.

At this time, the circuit 22 is turned off and the flap opens, covering the slot for inserting the token and the coincidence circuit 30 and 31 of the sensors of passage 7 and 6.

If passing by the sensor of passage 7 did not take place, after a certain time, the time relay 27 is triggered. The output pulse of the time relay 27 switches on the token emission control circuit 25. The token falls into a pocket

limited access, from where it is retrieved only by service personnel.

The output impulse of the time relay 27, which passes through the release element of the circuit 24, turns off the blocking trigger 23 and thereby brings the entire passage circuit to the initial position.

The next pass can insert his token. If a token is not inserted, then when passing by sensor 6, it triggers and issues a signal that passes through the open coincidence circuit 31 and turns on the turnstile closing control circuit 29. The turnstile is closed and kept closed while the passing gate is standing next to it and the pass sensor 6 is in operation.

If a passing person wants to exit when the entrance is switched to the entrance, he will come from the other side of the turnstile. In this case, the pass sensor 7 first triggers and generates a signal that passes through the coincidence circuit 30 n and turns on the circuit 31.

The turnstile closes and does not let pass through. When the passing one departs from the turnstile, the sensor of passage 7 turns off and the turnstile opens again.

When information is erroneously transmitted, the command "Error" is generated at the central point 1, which is fed to the controlled point 2g via the wire of the 4z line, passes through the coincidence circuit 19 and switches the trigger 17. At the same time, the connection unit 14 closes, the trigger 11 returns to the initial position and includes a token ejection control circuit 21 upon an error.

The potential level opening the matching schemes 18, 19, 28, 39, 40i-42 is removed and the controlled point is disconnected from the communication line. The control circuit of the pressing of the token 12 is switched on and the token falls into a pocket that has free access and is located close to the controlled point 2, -. At the central point 1, the error code is generated and output to the computer and to the tape punch.

A passer can remove his token from his pocket, re-insert it into the slot and, with proper secondary transmission of information, pass through the checkpoint.
