An embodiment of the present invention will be described below with reference to FIG. FIG. 1 shows an overall circuit block diagram of the device of this embodiment,
In the figure, the abnormality monitoring device according to the present embodiment includes an intrusion detector (1) that is installed in a specific monitoring area and that puts the specific monitoring area in a security state to detect unauthorized intrusion, and equipment in the specific monitoring area. a usage amount detector (2) that detects the usage status of the equipment, a setting device (3) that presets the usage amount of the equipment in the specific monitoring area, and a set value of the setting device (3) and the usage amount detector. A comparator (
4), and an AND circuit (5) that takes the logic condition of the output of nuclearization revenue (4) and the security status signal S3 of the intrusion detector (υ).
and an alarm device (6) that issues an equipment abnormality alarm based on the output of the AND circuit (5).

Next, the operation of this embodiment based on the above configuration will be explained. First, when the intrusion detector (1) sets the specified monitoring area in a security state and the security status signal S3 is output, the usage detector (2) detects the equipment (electrical equipment, water supply, etc.) in the specified monitoring area □. equipment, etc.) is used, and this amount of usage is detected. This detected value S and the set value S2 preset by the setting device (3) are input to the comparator (4), and the comparison result is outputted as the security status signal S3 of the intrusion detector (1). It is output from the AND circuit (6) on the condition that Based on this output, the alarm device (6) issues an alarm to notify that abnormal use of equipment has occurred in the specific monitoring area.

Note that the setting device (3) is set to an amount slightly larger than the maximum usage amount that the equipment would normally use when the specific monitoring area is in a security state.

Next, another embodiment in which the usage amount detector (2) is constituted by a power meter will be described based on FIG. 2. The abnormality monitoring device according to this other embodiment receives the pulse output S from the watt-hour meter (7) and uses the output S of the delay circuit (3) that causes a predetermined delay to output the p counter (9). After resetting the count value, the counter (9) is counted up every t seconds for a predetermined time by the clock signal s6 of the transmitter (10) until it receives a pulse from the person, and when the pulse from the watt-hour meter (7) is received. The count value at that time is stored in the latch circuit (11), and the stored value is output as the usage amount S (alarm) through the reciprocal converter (12).

Furthermore, when the intrusion detector (1) is in the guard state (defense If' which outputs the f number S5), the abnormality monitoring device according to the above embodiment detects the rising edge of the pulse of the guard state signal S3. The detection result is manually input to the counter (9) as a set signal, and the logical product condition of the detection result and the maximum value construction device (one set value) is taken. 0, which is a configuration in which the result is input as data to the counter (9).The operation of another embodiment based on the above configuration will be described.

FIG. 6 shows the operation as a timing chart. First, when the detection signal B3 during crime prevention security rises, the counter (9
) is inputted to the maximum value, and even if the clock signal S6 of the oscillator (10) is inputted as a subsequent count input, it continues to increase.

Therefore, the minimum value is input to the output S, l'i:.

Next, when one pulse output s4 of the electricity meter (7) enters, the counter (9) is reset at time T.
. The count if& of the counter (9) increases by one every second. Then, when the next pulse of the watt-hour meter (7) enters after T seconds, the value at that time, that is, T□/
1 is stored in the latch circuit (11), and its reciprocal value is calculated by the reciprocal converter () and output as an alarm S.For example, if T+''=60 seconds and t=1 second. , the value of the latch circuit (11) is 60, and the value of the reciprocal converter (]2
) is 0.01666. At this time, if the set value is 0.00055, the % information s, .

In addition, in the other embodiments described above, the usage amount detector was configured as a pulse-type wattmeter, but it is possible to use an analog-type wattmeter.
It can also be configured with a usage amount detection device that uses this AD converted value.

Further, the watt-hour meter in FIG. 2 can also be constructed using a water supply needle when detecting the amount of water supply. When the specific monitoring area is a tenant such as a building, the amount of electricity and water may be detected at the same time in the same tenant.

Furthermore, it is also possible to have a configuration in which an abnormality signal is sent to a central monitoring center or the like via a telephone line or the like at the same time as this alarm is issued.

Furthermore, an off signal may be issued to a predetermined device under control based on this alarm signal. The usage amount detector may be an analog value such as a voltage or current value as the usage amount.
