BEST MODE FOR CARRYING OUT THE INVENTION Embodiment 1 FIGS. 1 to 5 are views showing an embodiment of the first to seventh inventions of the present invention.
2 is a plan view of a room, FIG. 2 is an overall configuration diagram, FIG. 3 is a block diagram, FIG. 4 is a basic operation flowchart, and FIG. 5 is a basic operation timing chart. In the figure, the same reference numerals indicate the same parts.

In FIG. 1, 1 is a building, 2 is a room, 3 is a doorway of the room 2, 4 is installed in the room 2, and an individual card (hereinafter referred to as an ID tag) carried by an operator is detected to identify a specific individual. Is a monitoring area set by a monitoring sensor 5A (FIGS. 2 and 3) that detects the presence of a person. The monitoring sensor 5A includes an infrared sensor,
A passive sensor or the like is used.

2 and 3, in the personal identification device 4, when the ID tag 4A is operated, an ID code collating circuit 4B for collating with a pre-registered ID code, and a buzzer sound for sounding a warning buzzer. It has a circuit 4C and an external display circuit 4D. 6 is a controller, 6A is I
Based on the collation result by the D code collating circuit 4B, it is determined whether the intrusion monitoring input operation or the intrusion monitoring off operation is performed, the intrusion monitoring state storage table 6B is rewritten, the operation history is written in the database 6D, and the intrusion monitoring state storage is performed. It is an intrusion monitoring control means for instructing the external display circuit 4D to display the current intrusion monitoring state and intrusion abnormality detection state stored in the table 6B.

Here, the intrusion monitoring on / off operation is I
When the D tag 4A is operated and is entered, the intrusion monitoring OFF state (intrusion non-monitoring state) changes to the intrusion monitoring ON state (intrusion monitoring state). Further, when the off operation is performed, the intrusion monitoring on state is changed to the intrusion monitoring off state.

6C constantly monitors the monitoring sensor 5A, and based on the intrusion monitoring state stored in the intrusion monitoring state storage table 6B, instructs the buzzer ringing circuit 4C to ring a buzzer for warning, and detects an intrusion abnormality. When it is detected, it is an intrusion detection means that writes in the intrusion monitoring state storage table 6B and writes intrusion detection abnormality in the database 6D.

Next, the basic operation of this embodiment will be described with reference to FIGS. In step S1, the monitoring sensor 5A is turned off, that is, it is determined whether a person is present in the monitoring area. If it is off, the process proceeds to step S2, and if the monitoring sensor 5A is on, that is, no person is present in the monitoring area 5, the process proceeds to step S6. In step S2, it is determined whether the intrusion monitor is in the on state, and if it is in the in state, step S3
If it is off, the process proceeds to step S9.

In step S3, it is determined whether or not a timer (not shown) set to a predetermined length of time is being activated (temporary security). If the timer is not activated, the process proceeds to step S4 and the timer is set (provisional). (While being guarded), a warning buzzer sounds in step S5. If the timer value detects that the timer has expired in step S3, the timer value is cleared (temporary security release) in step S7, an intrusion abnormality is detected in step S8, an intrusion abnormality alarm is stored, and the outside of the personal identification device 4 is detected. An intrusion alarm is displayed on the display circuit 4D.

If the timer is being activated in step S3, the process jumps to step S5 and a warning buzzer sounds.
Then, the process proceeds to step S9, and it is determined whether there is an intrusion monitoring input operation at the present time, that is, whether the personal identification device 4 is currently performing an intrusion monitoring input operation. If the monitoring sensor 5A is turned on in step S1, that is, if there is no person in the monitoring area, the process proceeds to step S6 to determine whether the timer is being activated (temporary security).

If the timer has not been activated, the process proceeds to step S9, and it is determined whether or not there is an intrusion monitoring entry operation. If the timer value has detected the time-out, the timer value is cleared in step S7, the intrusion abnormality is detected in step S8, and the intrusion abnormality alarm is stored. If the timer is being activated, a warning buzzer is sounded in step S5, and it is determined in step S9 whether or not there is an intrusion monitoring entry operation.

Next, when it is determined in step S9 that there is an intrusion monitoring input operation at the present time, the process proceeds to step S10, and it is determined whether or not the intrusion monitoring is currently off. If the intrusion monitoring is off,
In step S11, the intrusion monitoring on state is set, and this state is stored. In step S12, the timer value is cleared (temporary security is released) to set the timer in a non-activated state, and in step S13, the warning buzzer is stopped and the process returns to step S1. If it is not in the intrusion monitoring off state at step S10,
Return to step S1.

Next, if there is no intrusion monitoring input operation in step S9, the process proceeds to step S14, it is determined whether there is an intrusion monitoring disconnection operation, and if there is an intrusion monitoring disconnection operation, step S15.
Proceed to and determine whether the intrusion monitoring is currently off. If it is in the intrusion monitoring off state, the process proceeds to step S16, and it is determined whether an intrusion abnormality has already been detected. If the intrusion abnormality has already been detected, the process proceeds to step S17, the intrusion abnormality is recovered, the fact that the intrusion abnormality alarm is not issued is stored, the intrusion monitoring off state is stored in step S18, and the process proceeds to step S12.

If no intrusion abnormality is detected in step S16, the intrusion monitoring OFF state is stored in step S18 and the process proceeds to step S12. Then, the timer value is cleared in step S12, the warning buzzer sounding is stopped in step S13, and the process returns to step S1. If there is no intrusion monitoring off operation in step S14, or if the intrusion monitoring off state is not in step S15, the process returns to step S1.
