In the card reader 4 of FIG. 3 (a), the card insertion indicator lamp 4b lights up during standby to prompt the insertion of a card, and when an ID card (not shown) is inserted into the card insertion slit 4a and slid, the card reader 4 Data including the ID code recorded on the ID card is output to the control panel 2. Then, in the card reader control panel 2, the CPU unit determines that the ID code from the card reader 4 and the ID code (data set and transmitted by the center device 1) previously stored in the memory section 2c of the card reader control panel 2 match. If the ID codes match with each other, the unlocking permission signal is output to the electric lock control unit 2b, and the unlocking signal is output from the electric lock control unit 2b to the electric lock (not shown) to unlock. Performs lock control. When the electric lock is unlocked, an unlock detection signal is returned from the electric lock to the card reader control panel 2, and the unlock detection signal is sent to the card reader 4 side through the electric lock control unit 2b and the CPU unit 2a. Then, the unlocking indicator light 4f is lit up. On the other hand, when the ID code is not normally read when the ID card is inserted into the card insertion slit 4a of the card reader 4, the card reader control panel 2 does not determine whether the ID code is coincident with each other so that the electric lock is released. Locking is not performed, and the CPU section 2a drives the card reinsertion indicator lamp 4c of the card reader 4 to light up to prompt reinsertion.

The card reader 4'shown in FIG. 3 (b) is the same as the card reader 4 with respect to the card reader insertion slit 4a, the card insertion indicator light 4b, the card reinsertion indicator light 4c and the unlocking indicator light 4f. Although it performs a function, the card reader 4'is further provided with a personal identification number input indicator light 4d, a personal identification number re-entry indicator light 4e, and a numeric keypad 4g.

In addition, in this system, when the electric lock is unlocked normally by the above procedure, or when either the operation of reading the ID code of the ID card or the operation of entering the personal identification number has made an error four times or more. Is determined by the CPU section 2a of the card reader control panel 2, and the card operation information indicating unlocking or error occurrence is transmitted to the center apparatus 1 side through the transmission section 2d through the multiplex signal line l.

FIG. 5 (a) shows the external appearance of the security key box 7 which is a key storage box, and FIG. 5 (b) shows its internal structure in a block diagram. The security key box 7 includes a card reader section 7a and a plurality of key storage sections 7e (key box) ... The operation of the security key box 7 will be described with reference to the flowchart of FIG. In FIG. 6 (a), when the employee of the tenant comes to the office, if the ID card is inserted into the slit of the card reader 7a of the security key box 7 (step 1000), the ID code of the ID card is transmitted to the CPU 7b. When the ID code (data set and transmitted by the center device 1) stored in advance in the memory section 7c matches, the lid of the key storage section 7e corresponding to the ID code is opened (step 1001). , The key (not shown) inserted into the internal keyhole (not shown) is operated to release the warning state of the entrance door of the tenant. Then, the key is removed, the lid of the key storage unit 7e is closed (steps 1002 and 1003), and the door of the company is unlocked with the key to enter the room (steps 1004 and 1).
005). That is, the control circuit section 7b and the transmission section are operated by operating the key inside the key storage section 7e to put it in the warning release state.
Since the warning release signal is transmitted to the center device 1 through the multiple signal line 1 through 7d, no warning is output even if the door of the tenant is opened. Further, when the door of the tenant is opened, the door sensor 8 detects the door opening, and this door opening detection signal is an interface circuit of the security key box 7.
The door opening information is output to the multiple signal line 1 through the control circuit unit 7b and the transmission unit 7d via 7f, and the door opening information is also output to and recorded in the center device 1. On the other hand, as shown in FIG. 6 (b),
When leaving the company, lock the entrance door of the company with a key (Step 100
6) Insert the ID card into the card reader section 7a of the security key box 7 and open the key box of the key storage section 7e (steps 1007 and 1008). Switch to (Step 100
9) By closing the key box (step 101
0), the entrance door is set to the warning state again. Therefore, the employee only has to carry the ID card and does not need to carry the key, which makes it easy to manage the key.

FIG. 7 is a block diagram showing the internal configuration of the crime prevention control panel 3, and when a crime prevention sensor 6 such as a door opening sensor or a glass breakage detector attached to a door or a window issues a warning, this alarm is issued. CP by receiving the signal from the sensor input section 3d
When it is necessary to output an alarm signal to the U unit 3a, the CPU unit 3a performs signal processing according to the data stored in the memory unit 3b (data set and transmitted by the center device 1), and then transmits the alarm signal. An alarm signal is transmitted to the center device 1 through the multiple signal line 1 through 3c.

In the center device 1, as will be described later, it is possible to preset a warning state or a warning release state according to time, day, month, etc., and automatically set a schedule. Release it,
It is possible to finely set the security monitoring state by the security sensor 6, such as setting the alert state only at night.

FIG. 8 shows that when the CPU part of the security terminal such as the card reader control panel 2, the security control panel 3 or the security key box 7 of the automatic door opening / closing device A runs away due to an external factor, it interferes with the multiple signal line l. Watchdog timer 2e, which is a runaway detection means for outputting a signal to prevent the operation of other normal crime prevention terminals from being hindered
The circuit of FIG. As an example, a watchdog timer is provided on the card reader control panel 2 of the automatic door opening / closing device A.
The case where 2e is incorporated is explained. The CPU unit 2a outputs the pulse signal of a predetermined cycle set by the internal program to the output terminal OU
Outputs continuously from T1, watchdog timer
While this pulse signal is being input to the input terminal IN1 of 2e, the watchdog timer 2e is outputting a "H" level signal from the output terminal OUT2, so the relay RY of the line breaking means 2f is not driven, Therefore, its normally closed contact rya,
The ryb remains closed and normal multiplex signal transmission is performed. However, when the CPU section 2a of the card reader control panel 2 runs out of control for some reason, the CPU section 2a does not operate according to the program, so the pulse signal output of a predetermined cycle from the output terminal OUT1 is cut off, and the watch The output of the output terminal OUT2 of the dog timer 2e becomes the "L" level, the relay RY is driven, the normally closed contacts rya and ryb are opened, and the card reader control panel 2 is disconnected from the multiple signal line l. The reliability of the system is improved by preventing the crime prevention terminal device and the center device 1 from being disturbed (corresponding to claim 2).

In this system, as will be described later, from the center device 1 side to the card reader control panel 2 of the automatic door opening / closing device A,
By transmitting the device type information, the card reader 4
Of the ID code of the center device 1 side, or the card reader control panel 2 itself based on the data stored in the card reader control panel 2 side (data set and transmitted by the center device 1), Alternatively, the person in charge inserts the ID card into the card reader 4 and inserts the ID card into another card reader installed in the control room, and unlocks the electric lock only when both ID codes match. It is possible to perform such control. In addition, by setting a schedule on the side of the central device 1, the electric lock can be unlocked only by operating the ID card depending on the time of day, or in addition to the operation of the ID card, the PIN code can be entered using the numeric keypad. It is possible to automatically perform a switching setting such that the electric lock is unlocked when it is performed (corresponding to claim 5).

In this system, based on the data transmitted and stored from the center device 1 side to the crime prevention terminal device (the card reader control panel 2 of the automatic door opening / closing device A or the key storage box 7),
Of the magnetic data recorded on the card, the card reader 4
(Or, the range to be read by the card reader unit 7a of the security key box 7) can be arbitrarily set. Therefore, as shown in FIG. 9, for example, magnetic data recorded on an existing ID card such as an employee card.
Since only the area E1 in which the employee code and employee name required for this system are written in C1 can be read by the card reader 4 (card reader unit 7a),
It is possible to use existing cards without creating a new dedicated card for this system. In the present system, the area E1 necessary for reading the ID card data is read by the card reader 4 (card reader unit 7a). However, the present invention is not limited to such a structure, and for example, a card reader may be used. It is also possible to selectively signal-process only the necessary data on the card reader control panel 2 (security key box 7) side after all the data C1 has been read by the card reader 4 (card reader unit 7a).

FIG. 10 is a restoration for automatically reading data related to the security terminal device from the center device 1 after the security terminal device is repaired when the security terminal device such as the automatic door opening / closing device A fails. This is an explanation of how to use the card. For example, when the card reader control panel 2 breaks down and the power supply is cut off, all the data such as the ID code and the set secret code stored in the internal memory unit 2c will be lost. After the failure of the reader 2 is repaired, it is necessary to sequentially send out all the data regarding the security terminal device from the center device 1 side, which is very time-consuming. However, if the data recovery data SC of this system is used, the card reader 4 provided on the side of the card reader control panel 2 that has repaired the failure (the same applies to the card reader unit 7a provided on the security key box 7) When the data recovery card SC is inserted, a data transmission request signal is sent to the side of the center device 1 and the data acquisition work regarding the card reader control panel 2 in which the failure has occurred is automatically performed. Even if it does not exist, it is possible to easily restore the state before the failure.

Next, the functions performed by the program on the side of the center device 1 will be sequentially described with reference to the display contents of the CRT screen of the center device 1.

FIG. 11 shows a menu configuration of various operations displayed on the color CRT 1c by the program when operating the center device 1.
