Abstract

The invention relates to the extraction technique and can be used for centrally monitoring and recording information for timekeeping. The device provides high reliability. Each channel of the device control consists of two photo sensors installed in the aisle zone, blocks, readings of information from a pass or a token, an indicator, a memory block and a key. At the output of the key, a signal to turn on the actuator of the valves that block the passage is formed. With the correct passage and operation of the device, the indicator reflects the code specified in the token. The polling of the control channels is performed by the switch according to commands from the pulse generator, the address code generator, and the pulse generator. Compiling and issuing information is carried out by the information receiving unit, the counters, the register and the decoder. 1 il. sl to eat od about 05 cl

The purpose of the invention is improving the reliability of the device.

The drawing shows a block diagram of the device.

The device contains .jeton 1 information storage, blocks 2, - 2 readings, sources 3, - 3 ,, „, 2.1 Зг.г) of light, photographic receiver 4 ,,, - 4 ,., 4, - 4, п ( second photosensors), keys 5, - 5, and, blocks 6, - memory BC, blocks 7 7, galvanic isolation, command 8, indicators 9, - 9ji, switches 10 - 10. (actuators of the valve mechanisms, information receiving unit 11, register 12, first counter 13, second counter 14, pulse generator 15, address code generator 16, pulse generator 17, decoder 18, first and second recorders 19 and 20, reflecting registration block 21 Elements 2-7.9 in one ton in the control channel.

The device works as follows.

At the pass-through enterprise, the optically coupled light sources 3 {, i and the corresponding photodetectors 4, -4,, 4, -4j control the movement of workers in the direction shown by arrows, and it is possible to turn on the drive of the gate mechanisms, which prohibits this promotion. When an employee passes by the first pair of optically coupled source and photodetector, for example, 3 ,, and 4 4., the receiving receiver 4 4 ,, generates a signal arriving at the input of the key 5, which gives a signal to the switch 10 ,, of the drive mechanism bolts, prohibiting the employee far-neck promotion.

In order to obtain a permit for advancement, the worker must place the individual storage token 1, for example perfozheton, to the position for reading the information in block 2 of the reading. The generator 15 produces pulses at the input of the switch 8. Under the action of these impulses

cov switch alternately establishes a session with one

It is from blocks 7f - 1. These same pulses come to the input of the imager, from which the signal through the switch 8 enters the communication line and interrogates the galvanic isolation unit with which the communication session is established, for example 7,. In addition, the pulses from the output of the generator 15 are fed to the inputs of the counter 13 and 14 and zero them.

The transmission request signal passes through the galvanic isolation unit 7 to the second input of the memory unit 6, the latter remembers it and outputs to the unit 2 readings, which outputs a sequence of signals through the unit 7, galvanically separated to the switch 8, passing them to the receiving unit 1I . This block selects from the sequence of data signals and clock pulses and outputs them to the first and second outputs, respectively, the information is fed to register 12, the signals received by the receiver are counted by counter 14, and the clock pulses by counter 13. At the end of the communication session, The signal that is known in advance by the known number of clock pulses. The signal from counter 13 goes to the decoder 18, which analyzes the number of data received by the counter 14. And if it corresponds to a predetermined number, it outputs the signal by. whereby the recorders 19 and 20 record information from the outputs of the recorder 12, and the driver 17 sends an acknowledgment signal to the galvanic isolation unit 7f and the 6f unit 7f, indicating that the information is registered by the system. Block 6, having received this signal, generates a signal on its second step, including indicator 9, indicating data read by block 2, reading from a token 1, and also a signal to the second input of key 5, prohibiting the passage of a signal from a photodetector 4 ,,, on the switch actuator mechanism latches.

The employee, seeing on the indicator 9 the number corresponding to his personal personnel number, retrieves his individual information storage 1 token from block 2 (reads and passes unhindered the first sources and photodetectors 3, and then the second 3, and 4, while the signal from the last photodetector 4j, is fed to the first input of block 6, the memory and sets it to its initial position.

If the information is received incorrectly, for example, due to interference in the communication line, this is detected by the decoder 18 and the driver 17 does not send an acknowledgment signal through the switch 8 to the communication line. Then the information transfer is repeated at the next communication session after the switch 8 services the remaining galvanic isolation units.

The speed of the alternate establishment by the switchboard of 8 communication sessions with galvanic isolation and information exchange blocks is much higher than the speed of workers passing by the photoreceivers; therefore, the system is able to serve a large number of geographically dispersed walkthroughs without reducing their throughput. The addition to the individual token of storage 1, in addition to the code of the personnel number of an additional number, makes it possible to increase the reliability of the system of timekeeping. When using a perfozheton as a token, for a swiftly changed personnel number (for example, to register someone else's personnel number by your storage device), it will be necessary not only to glue the hole in the perfozheton, but also to make a hole in that part of the token where the additional number is coded.

The registrar 19 performs the processing of the received information, supplements its information about the employee's personnel number and generates the documents for the accounting. A digital computer can be used as such a registrar. The registrar 20 operates in parallel with the first registrar, its task is to record the incoming information onto a tangible medium, for example, punched tape or tape, or cassette, without processing. If the registrar 19 is not ready to receive information, the information is accumulated by the registrar 20, and then information from the tangible medium prepared by the second registrar is entered. The reliability of the system

increases as sufficiently constant performance of at least one registrar. In practice, the reliability of the second recorder is significantly greater, since its functions and hardware complexity are lower than those of the first one. The device controlling the advancement of the enterprise workers at the checkpoints eliminates the possibility of several workers entering and exiting the enterprise when using one information storage device, blocking the access points when trying to pass several people with one information carrier, And, on the contrary, does not allow registering two carriers information. The use of two-wire communication lines between the peripheral interfaces and the switch allows to reduce the number of communication lines, which reduces the cost of the system and increases the reliability of its operation.

Thus, the essential differences of the proposed system in comparison with the known ones is that it includes a lighting device, photo detectors, digital indicators of personnel numbers, actuators of the mechanisms of valves, lock registers, keys, galvanic isolation blocks, switch, receiving device, register receiving information, received data character counter, clock counter, decoder, transmission request signal generator, acknowledgment signal generator, second information recorder, their mutual understanding between themselves and the rest of the system,

As an electronic object, the basic colchid 10 is designed to automate timekeeping,
