Description

DETAILED DESCRIPTION OF THE INVENTION This application relates to the field of doorway security systems, and more particularly to the field of card readers for doorway security systems.

Door security systems using magnetic card readers at the door to be controlled are known in the prior art. Such a system has multiple reading positions. with a central control unit connected to a central control unit, each of which is located at a particular door to be controlled. It is located in

A person authorized to enter or exit through the door inserts a magnetic cart into the reader hole. At that time, the magnetism on the card, the air. - the code is read and the data is passed to the control device, which decides whether to grant or deny entry and leaves the door locked; Or tell them whether to unlock the door or not.

Such systems can also be conveniently used as hourly employees to keep records of their working hours. I can do that. However, when a large number of employees simultaneously record their arrival and departure times, a problem arises in the throughput of the system.

It reads the input card, waits for a poll signal coming from the controller to the reader, sends the card data to the controller, which processes the information and outputs "GO'' or "x Oa.
O) + The delay caused by waiting to send the signal back may irritate the employee at the end of the line.

Such a card reading system is 1c, 711! It can be used to connect alarm contacts located at strategic locations throughout the facility.

In the prior art, a centrally located alarm contact monitor was located near the control device, and each contact monitor (individual wires to the alarm contacts located throughout the tall body) It was connected by A7.
Although such a system is effective, it requires a separate polling protocol and associated hardware for the V1 contact monitoring device. Furthermore, individual wires must be communicated between all of the contacts to be monitored and the central supervisory 8A device. This would be a significant expense for the line. Moreover, such central contact monitoring devices are usually not suitable for applications where only one alarm contact needs to be monitored. This is because its functionality does not justify the expense.

Prior art systems also have scope for regional improvements in operation between the reader and the central processing unit should the communication line between them be interrupted. In such a situation, if all admission were denied, people would be inconvenienced, or worse, would be placed in an unwanted emergency situation. Alternatively, it would be possible to allow free entry through the Libe C door. However, for record-keeping functions performed by a central control unit, there will not be a record of each person who enters and leaves a particular area during a particular time when the line is out of service.
, so that even if theft occurs during the period of outage, the mouth,? There are probably no records left that could be used for investigation.

SUMMARY OF THE INVENTION Disclosed herein is a cart reader for use in a security and security system that controls entry by Jζ to a door equipped with a lock, The system has a central control unit whose card reader reads magnetic data recorded on a card held by an employee, etc. The card has a system code and a 1.D .

I'm playing the code. The card reader has time and attendance functions to act as a timer in reading the data permanently recorded on the card and sending it to the central control unit for processing. 3, then the central controller grants or denies entry based on the data on the card. In addition to this, improved card reading devices have also been developed to read some portion of the data on the card and to transmit the remaining portion later to the central controller. , the decision to grant or deny local admission can be made without interacting with the controller. Typically, this reads the SYSTEM=1-code and indicates that the SYSTEM_1-code on that card is the system_1-code on the programmable switch.
This is done by providing authorization if the code matches. At that time 1. D.

is stored in a buffer along with the date and time of its processing for later transmission to the medium heat control device. This section eliminates the need for each employee to wait for an acknowledgment IM from the controller, which would otherwise be delayed while processing other messages from other readers. Avoid increasing the amount of system processing.

Improved card readers can also sense when communication with a central controller is lost and, based on data on the card, can accept or accept data without consulting the controller. You can refuse. During the time that communication with the central controller is lost, authorization is granted and I
ζ 1 from the 111 cards for each employee. D. The card reader stores the data in a buffer for later transmission to the central control HWi.

Improved cart reader also? The state of the contacts of the keying device can be monitored and changes in this can be reported to the central control device. The central controller can be programmed to make a conditioned response to the reader connected to the changed contact, or to any reader in the system. The response message can change the state of one or more relays within the reader, thereby causing any device connected to the relay or relays to change state. Indicates that action is required in response to an alarm contact.

Referring to Figure '13, there is shown a flow diagram of how CP jJ unloads a buffer. During the blue routine, the CPU 66 continuously checks for the presence of a ball signal from the center side jll device σ. When the ball finally arrives, the reader knows that the communication has been re-stored. This monitoring (function is shown in Figure '13)

If there are no pending time requests, CI) U 66 mjf Ml the ball in state F554 and returns to the monitoring routine. .

Returning to state 548 in FIG. 13, if the process to be sent is in buffer 88, CPU 66 retrieves 1 process data liY, assembles it for serial transmission, and , DO data bit line 68. Driver 70. Address line AO-2, King X data line 5
8J3 and an isolation board 5/l to send it in the manner described above. The 771-mat for transmission in the preferred embodiment indicates the type of reading device and the type of processing elicited.
This is a header that identifies the data that follows. Following the condition code, 1. from the card. D. Data is sent along with the date and time when processing occurs. These steps are represented by block 556. However, any A-pine I~ for processing will be active. Control then returns to the monitoring routine.

Turning to FIG. 14, there is a card reading device;
14 is a flow diagram of the steps for monitoring the alarm wave L contacts connected to line 30 from the CCM/COM board 90. The routine shown in FIG. 600 per second
3, which is intended to detect a flag line 4'1 indicating the state of the alarm device contacts when the alarm device contacts have run out;
The first step is to read the CCM Nora flag to determine the last state of the flag. This step is represented by block 560 in FIG.
A l l it5 selects an address every 7 lags N in RAM 33 /1 of FIG. 7 and connects to decoder ζ 338 to drive line 336 low.
RAM is selected on the and VMΔ lines] and then its address is written on line 242. R of RAM 334
/W is driven to the read state by microprocessor 6G in FIG. 68.

There are four possible states for flags that represent the states of ``Hi 't) Closed'' and (). It is possible to accept cases such as ``inquiry and not reported'' or ``closed and not reported.''

One 8-pitsu I is used to represent these states.

If the flag does not indicate 1 "Reported closed", C
PU 66 must know whether alarm contact N has changed state since its post-H state as indicated by flag N. Therefore, the CPU 6G causes the alarm device contact N to be read. This step is
By selecting the address 5 (represented by the transfer to the 10x 566 on path 31 and contact N) and placing that address on the Alternative 1 node 330 on line 332 in FIG. Physically completed.,C
PU 66 also utilizes a 75 signal connected to bin 15 of multiplexer 330 to enable multiplexer 330 in a known manner.

The C8CCM signal can be generated by a decoder connected to the node address bus of the CPM 66 or by other conventional methods. At the address on the set of lines 332, multiplexer 330 selects one of its outputs XO-X7 for connection to the 1]7 line coupled to CPU 66 data bus 64. C.P.
U 66 then optical isolators 321-32
The desired contact point can be read through one of the backs of 8.

If the alarm contact N is heard, the CPU 66
Knows that the alarm contact has changed its state since the last time it was read, and that this small event should be reported. Therefore, the CPU avoids changing the state of flag N to "heard but not reported" state. This action is represented by the transfer on path 567 to block 568 in FIG. one of the status words held in RAM in
Bits must be updated to 4tl, the status word should be changed to 1 to 1 for each interim device contact, and bits 1 to 1 for contact N should be changed to accept the new state of R. be done. This action is represented by the transfer to daily check 570 on path 569.

After the status word has been updated, the CPLJ 66 is ready to operate to read the next flag. To do this, N must be incremented by 1. It is represented by path 5571 of block L1 block 5721\.

After N has been incremented, CPIJ 66 must know whether it has finished reading all flags d3 and contacts. To do this,
C1-)U compares the value of N after incrementing 1 to the total number of alarm system contacts connected to line 3o in FIG. In the preferred embodiment, this number is 7, but it depends on how much hardware is utilized.
It can be any number depending on whether the number is 1 or 1. This comparison operation is performed at block 574 in FIG.
niJ is expressed as r. If N is less than or equal to 7, the CPU returns to state 560 via path 5761,
If N is greater than 7, then the flag reading task is completed and the CPU 66
Return is made to the monitoring routine as indicated by 78.

b, and if flag N is in the "heard and reported" state, C
P U 4 Again, it becomes known whether there has been a change in the state of the alarm contact associated with flag N. To determine this, CPLJ 66 reads contact N. This operation is represented by path 582 to state 584.

If contact N is open, there is no change from its last state and CPU 66 is ready to read the next flag. N is incremented] and the processing continues as described above. This operation is represented by path 586 to state 572, previously mentioned d1.

If contact N is closed, CPLI 66 knows that there has been a change in state since the last tick. Therefore, CPU 66 must let 7 lags N and turn 4H to indicate that contact N is now closed and not reported. This operation is represented in FIG. 14 by the transfer on path 5ε38 to state 9o, P+
, 'c, ru.

Because of a change in the state of one of the alarm system contacts,
The status word must be updated().

This operation is represented by the transfer of path 5920 to state 570. Processing then continues as described above.

Returning to state 560, if the reading of flag N is complete and the state is "r IWJU and +1 notated", then CPU 66 reads contact N and determines if it is still closed. If the alarm signal is found to be present, there has been no change in the contact condition since the last reading. Thus, there is no need to change the flag state, and no need to change the status word. Therefore, the CPU 66 sends the route 5 of state 5721\ to ip.
Increment N as represented by the 67 transfers. .

Processing then continues as described above.　　.

Moshi fta 5 C30ni d3 E C1CF' U
If 66 determines whether flag N is 1, closed and not reported, or ``heard and not reported'', there is no need to read the alarm contact.
This means that the central control unit F (has not yet been notified of the change in the state of the alarm contact that causes the flag to be set to one of these two conditions) Because reporting is the first priority, CI
) U 66 simply updates the status word to indicate the new status and continues reading other flags.

This operation is the path 600 to the lζ state 570 described earlier.
The transfer of - is expressed as J- and is C.

Referring to FIG. 15, a change line 41 on the alarm contact connected to line 30 to the central control 311 ml 20 in the first 15 shows the steps taken by the CPU. The routine shown in FIG.

is executed.

The first step is to determine whether flag N has been reported or is currently in an unreported state.
The next step is to read flag N for P LJ 66.

If a change in the alarm contact N that changes to the state is not reported to the unreported state as shown in the flag N, the CPU 66 will When the purchasing contact N changes, 1 [00M message is sent to the central control m1''!A, so-called 20 while reporting the condition.
and CCM messages are transmitted to the central controller, represented by the transfer of block 608'\ onto path 60G. Referring to FIG. ] Sent by placing it on the line.

Address hit line AO-A2 is CP LJ 66
is held at the address that connects the DO data line 1- to the 1x data line 5B. The direct IJ data CCM message then passes through an optical isolator with isolation code 5/IJ- and over data line 28 to central controller 20 in FIG.

The next step after transmitting the CCM message is to
For U G 6, whether the flag is asked or closed to determine whether the flag should be changed to [closed and reported state] or [open and reported state]. This is a legal requirement. This step is represented by a transition to state 612 via path 610.

If the flag has been heard, CPU 66 uses the path (

Change the status to ``Closed and Reported.'' This is represented by a transition to state 620 on path 618. Control then returns to state 602 via path 622. Processing continues from state 602 to state 604 where flag N is read again. Indicates that it has been reported to increment 1. This is represented by the transfer to state 624 by path 642. l+ c P LJ 66 then returns to state 62
Compare the number of N with the maximum number of IFL_/N_ flags read, as represented by the transfer on path 626 to 8. If N is less than the maximum number of flags to be added to the system, the control 910 returns to the monitor via path 630. Then the monitor returns to the routine of Figure 15.
CP LJ (36 reads flag N11.

If N is equal to L) the number of flags in the system, then
It is only necessary for the CPU 66 to complete reading all flags and determine whether the central controller 311 unit 20 has requested a CCIV+status word. This decision is represented by a transfer to state 034 via path (532).
0 requests the 00M status word - then control returns via path 636.

If the medium fire system ill station requires the 00M status word (

If so, J, which is represented by a transfer to state 6 = 1.0 on path 638, is 1) (state 2):
It will be done.

After that, the control changed to 'tR642' and then t? ii Return to view.
