Embodiment 1 Hereinafter, a security system according to the present invention will be described with reference to the drawings. FIG. 1 is an overall configuration diagram of a security system according to the present embodiment. In the figure, 1
Is a telephone set in each of the tenant's and manager's offices. This telephone 1 has a built-in human body detection sensor 2, and a human body detection signal from this sensor 2 is transmitted to the PBX 3 A via a telephone line (extension) 4. Can be

The human body detection sensor 2 described here is a passive type sensor that detects a human body by sensing the temperature of the human body or infrared rays emitted by the body temperature, or a magnet type sensor that detects a human body by detecting magnetism emitted by the human body. And the like.

Reference numeral 6 denotes a tenant information management terminal (HOST-PC) installed in an administrator room or the like, which is connected to the PBX 3A by a transmission cable 7 and a telephone line (extension) 4.

FIG. 2 shows a detailed view of the inside of the PBX 3A.
It is a detailed block diagram of a BX part. In the figure, 3-a is PB
The CPU unit 3-a controls the entire operation of the X3A. The CPU unit 3-a transmits a line connection command to the line switching unit 3-b, communicates with the HOST-PC 6 via the I / F unit 3-c, and transfers data without a connection. Activate / deactivate functions. Reference numeral 3-b denotes a circuit switching unit. The circuit switching unit 3-b connects a line according to a number input from the telephone 1 or a connection command from the CPU unit 3-a. 3-c is an I / F unit, and this I / F unit 3-c is H
A transmission cable 7 for communication with the OST-PC 6 is connected to the CPU unit 3-a. Reference numeral 3-d denotes a line accommodation card to which the telephones 1 of each tenant, manager's office, service entrance, security company, etc. in FIG. 1 are connected.

Next, the operation of this embodiment will be described with reference to the system operation flow at the time of sensor detection shown in FIG. First, when the system is activated (step S500), the human body detection sensor 2 provided in the telephone 1 installed in each tenant detects the presence / absence of the user of the telephone 1 (step S501), and changes the state. The PBX 3A is notified in real time by the detection signal. PBX3A CPU
Based on the presence / absence state notified from the telephone 1 of each tenant (step S502), the unit 3-a performs normal line switching (release of the call forwarding function) (step S503), and a predetermined call forwarding function when absent. (Step S50)
4).

At this time, the PBX 3A simultaneously notifies the HOST-PC 6 of the presence / absence of each line as tenant data in real time. After checking the registration of the presence / absence of each line from the tenant data (step S505), the HOST-PC 6 uses the presence / absence state of each line notified from the PBX 3 to determine the presence / absence of each line in the tenant data shown in FIG.
The absence status is updated (step S506).

[0021] Here, it is determined whether or not the update is to the presence (step S507). If all the lines registered in a certain tenant are absent (step S509), the state is not changed after a predetermined time T1 has elapsed. Update the security status of the tenant during security (steps S511, S524 to S52)
6). If any one of the lines registered with the tenant is present before the elapse of T1, the security state is not set.

Thereafter, when the line state of the tenant in the security state changes to the presence state (when a request to switch to a mode in which reception is possible is issued) (step S507), it is determined whether the tenant is in security. (Step S50
8). If it is determined that security is being performed, it is determined that the human body detection sensor 2 has detected an intruder. And HOS
When the T-PC 6 detects the occurrence of the intrusion abnormality of the tenant (step S510), the T-PC 6 records the abnormality occurrence and simultaneously issues the report order of the report destination data shown in FIG. 4 (administrator → OOO security company → administrator mobile phone). HOST
Dial the notification destination from one PC6.

That is, first, the report order n is set to 1 (step S512), and the n-th data in the report order is searched (step S513). Then, as a result of the data search, it is determined whether or not there is report destination data (step S514). If it is determined that there is no report destination data, the process returns to step S512. If there is report destination data, it is determined whether the report destination is in the tenant data (step S515). If it is determined that the report destination data is present, it is determined whether the line state is present (step S51).
6) If present, R is initialized to 1 in order to count the number of retries (step S517).

If the number of retries does not exceed the number of retries Rmax, dial the dialing destination and attempt a line connection (steps S518, S519). If not connected, 1 is added to the current number of retries, and the process proceeds to step S518 (step S520). If the line connection is made, the notification destination is notified of the abnormality occurrence status (step S521,
S522).

In the above-mentioned calling of the report destination, if the report destination does not respond even if the number of retries exceeds the number of retries Rmax (step S518), the HOST-PC 6 returns to step S513 and advances the report order by one. Dialing to the next destination in the order of notification registered in the destination data is performed again (steps S513 to S522).

However, at the time of this notification, if the telephone number of the notification destination is registered in the tenant data shown in FIG. 3,
The presence / absence state of the line is confirmed (step S516),
If it is not present, 1 is added to n in order to advance the order of issue without issuing an alert to the issue destination, and then the data of the order of issue is searched (steps S523 and S512). If it is determined in step S515 that the notification destination is not in the tenant data, the process proceeds to step S517.

After the dialing, if the report destination responds, the HOST-PC 6 notifies the abnormal occurrence tenant No., the name, and the state of the abnormality occurrence by voice 1 (when the report destination is a normal telephone), or A predetermined abnormality occurrence code is notified (when the destination of the notification is machine reception) to notify the local abnormality occurrence state.

It should be noted that the security of the tenant once in the security state is released from the HOST-PC 6 by an extension telephone such as a public entrance or an external line (public telephone, portable telephone, etc.) to the HOST-PC 6.
o and PIN No., or HOS
This can be performed by performing a release operation on the T-PC 6.

Since the security release of the tenant as described above continues for a predetermined time T2, the security is released as it is if the tenant enters the tenant and changes the presence / absence state of any one of the telephones 1 to the presence. If all the presence / absence states of the telephone 1 of the tenant remain absent even after the lapse of the predetermined time T2, the tenant enters the security state again.

FIG. 6 shows a system operation flow when tenant security is released. That is, when the tenant security release processing is activated (step S600), the user dials the security release telephone number (step S601), and inputs the tenant No. and the password No. (step S602).

If the input is OK (step S60)
3), tenant security release (step S604), and timer T2 is started (step S605). It is determined whether or not any of the human body detection sensors 2 in the release tenant is present, and if the absence state is determined even after the timer set time T2 has elapsed, tenant security is activated (step S).
