AUTOMATIC CONTROL POINT

one

This automatic control point (automatic transmission) is intended for enterprises (organizations) with access control system, both without the removal of a permit from the territory of the enterprise, and with the removal of it.

An automatic checkpoint is known, consisting of a pass key with a encoder sensor, a lock mechanism, gate valves and two decoders, one of which transmits information to a puncher, the other through independent channels to a control digital printing machine.

The block diagram of the item contains a skip receiver, code relays of the working and control decoders, two time registers, bit contacts and digital buses of the working and control decoders, read, punch and print control circuits, two readers, interlocking circuits during punching and control, a common circuit interlocks, lights, actuators, summing machine and hammer drill.

The key pass is made in the form of an envelope with windows in which the passport holder's details are placed under the transparent film. The personnel number in binary-decimal code is applied in the form of protrusions on the front part of the pass.

However, for the badge receiver, built on the principle of code relays, frequent failures are characteristic due to the unreliability of the mikrorele;

The reading of the passport details is controlled by additional devices with data on the perforator and the summing machine, which is economically disadvantageous;

possible loss of information even due to single failures of the reader;

the perforator and the summing machine are given the time it takes for the workers to pass through the automatic transmission system, and not only for those who violate the regime.

The purpose of the invention is to increase reliability

readout of perforations at the pass of details, detection of failures of the readout block and correction of single failures, reduction of laboriousness of processing the data obtained on the punched tape with the help of electronic computing techniques, elimination of the possibility of passage through the automatic transmission through a false pass, increasing the throughput of the automatic transmission and elimination of excess score information.

The proposed control bandwidth

The item is characterized by the fact that a matching scheme, a correction unit, a block of current modes and shifts, read control blocks, skip control, mode control and shift control, and an additional memory block are entered into it.

The drawing shows a block diagram of the proposed device.

The key pass is made in the form of an envelope with windows in which the passport holder's details are placed under the transparent film, and the personnel number, workshop number, shift number and owner's mode are punched on the pass.

Automatic control

the point consists of a read start block / connected to read block 2 and parallel to time block 3. The read block is connected to memory block 4 and skip control block 5,

The memory unit 4 is connected to the control unit skip 5, in parallel to the control unit read 6 and the correction unit 7, to the matching circuit 8 and the additional memory unit 9. Time unit 3 is connected to the memory unit 4 and in parallel to the display unit 10, unit current modes and shifts 11. The control unit skip 5 is connected to the control unit read 6 and the display unit 10. One output of the control unit read is connected to the control unit 1,2 and the other parallel to the correction unit 7 and the control unit 12. The correction unit is connected to memory block 4, indication block 10 and the control unit 12. The co-ownership scheme 8 is connected to the additional -frame 9 unit. The block 9 is connected to the information output unit 13. The display unit 10 is connected to the “Pass,” Go, “Fail,” Not Pass, “Shift.

One of the outputs of the block of current modes and shifts 11 is connected to the shift control unit 14, and the other is parallel to the mode control unit 15 and the display unit 10.

The control unit 12 is connected to the memory unit 4, the display unit 10, the control unit is bold 14 and the power unit 16. The information output unit 13 is connected to the control unit 12 w by a perforator 17. One of the outputs of the shift control unit 14 is connected to the display unit 10, and the other is located parallel to the control unit 12 and the mode control unit 15. The latter is connected in parallel to the memory unit 4 and to the coincidence circuit 8. The unit 4 is also connected to the shift control unit 14 and the mode control unit 15. The turnstile unit 16 is connected in parallel to the unit issuing information 13 and block display 10. Sensor 18 is connected to the time unit 5.

The worker who approached the turnstile shutters, a kind of highlighted banner "Pass, inserts the key pass (face up) into the receiving slit of reader 2. After this, the read start block 1 generates a control signal" There is a pass to read block 2 and parallel to time block 5. Block 3 accumulates minute pulses from sensor 18 in a form convenient for storing in block 4 and delivering “a puncher 17.” By a signal “There is a gap, it sends the current time to block 4 and to display block 10 for flashing. The read block 2 reads the information that is perforated at the pass through this signal and transmits it

in the memory unit 4. After reading the information, the unit 2 generates the command "End of reading to the control unit skip 5, which by this command checks whether the information was read from the passage, after which

generates a "Skip to read control unit 6" signal when reading information from the pass or a "Do not skip signal to the display unit 10 if the information is not read from the pass.

The display unit by the signal "Not skipping flashes a banner" Not skipping. When flashing this banner, the worker must check whether the pass is correctly inserted into the receiving slot of the reading unit.

2, and then paste again.

The read control unit 6 by the signal "Pass controls the read information. The read control is based on the use of correction codes with a distance of 2 to detect all single and double faults, as well as some faults of a higher order.

In the event of a failure, the read control unit 6 generates the signal "Is

control unit 12 fails to count

total number of failures and correction block 7,

and if there is no failure, the “No fail

control unit 12.

On the signal "There is a failure of the correction block 7

ipd, bad bits. With single faults, it corrects the failed bits in memory 4 and generates a "Corrected for control unit 12" signal. If a higher order fails, block 7 cannot

correct the read information and generates a signal “Failure on the indicator block 10, which, using this signal, highlights the corresponding transparency. When flashing the banner

The worker again inserts the gap and the receiving slit of the reading unit or moves to another reading unit.

The signal "No failure or" Fixed control unit 12 generates a command

“Control of the shift to the control unit 14.

Using the command "Change control, the / / / unit compares the shift number received from block 4 with the shift number from the current mode and shift block 11, and in the case of the forest comparison, issues the command" Change PA display unit 10, and in the case of comparison, the command "Control of disturbance to the mode control unit 15 and in parallel to the control unit 12,

The display unit 10 by the command "Change highlights the corresponding banner. An employee who flashes this banner should check that the shift on the pass coincides with the current one and should be addressed to the pass office.

The mode control block 15 on the command Violation Control compares the mode read from the pass, i.e. received from memory 4, with the allowed modes coming from the block of current modes and // shifts, and in the case of incompatibility with none of the of the modes generates a control level "Violation of the mode on an additional memory block 9 for marking the violation of the mode and in parallel - on the circuit" AND 8.

Allowed is the mode of operation in which the employee can currently pass through a checkpoint, taking into account the shift. The block of current modes and shifts // based on the analysis of the current time from time block 3 generates the permitted modes and sends them to the mode control unit 15 and the display unit 10. The control unit 12, having received the command Violation Control, generates a series of control commands: "Issue in the BBP (buffer storage unit), to the memory block 4, “Open the turnstile to the turnstile block 16 and“ Go to the display unit 10.

Block 4, by the command “Issue to the BBP, transmits the code bits of the details through the direct connection and the bits of the time, through the scheme“ AND 8- to the additional memory block 9.

The & 8 scheme skips the time bits to block 9 only if it receives the control level Violations of mode from the mode control unit 15. Following the command "Output to the UPS after the time required to transfer information from the memory block 4 into the additional memory block 9, the control unit 12 generates the commands Open gate and Go.

At the command “Open the turnstile, the turnstile unit 16 unlocks the turnstile to rotate 90 ° to let one person through. By the command “Go, the display unit 10 extinguishes the banner,“ Pass and highlight the tralsparant “Go. Rabotpik passes the turnstile and thereby raises it. 90 degrees. After turning, the turnstile is locked, and the turnstile unit 16 generates a control signal. 1. Signal "Passed to the information output unit 13 and the display unit 10. The signal from this signal

the display extinguishes the banner "Go and highlight the banner" Pass, and the information output unit 13 issues the contents of the buffer storage unit 9 to the perforator 17 and, when the perforation is completed, issues the command "End of the perforation to the control unit 12. The last memory remembers this command and next time the commands “Issue to the BBP,“ Open the turnstile and “Go out is generated by the command“ Control violation in the presence of the command “End of perforation.
