。In conventional intruder detection systems, detectors are fixedly installed, so the detectors are installed at locations where intruders are expected to pass through. For this reason, many detectors were required and the wiring became complicated. In addition, since the detectors used were based on a single detection principle, they always had weaknesses in detection, such as giving false alarms or not being able to issue an alarm if there was an actual intruder. There was a drawback.

知方式を提供することを目的とする。The present invention was made in order to eliminate the above-mentioned drawbacks of the conventional technology, and it is possible to obtain a wide detection area by making one detection part rotatable in all directions around it. The object of the present invention is to provide an intruder detection method in which the detection unit has two detection means with different detection principles, thereby mutually compensating for the weaknesses of each detection principle and increasing the reliability of the detection unit. do.

The detection unit 11 is configured by the following. 3 is a motor that rotates so that the detection unit 11 can face in all directions; 4 is an ultrasonic signal processing unit; 5 is an infrared signal processing unit that performs amplification, detection, etc. on the output signal of the infrared detection unit 2; 6 is a motor drive unit that drives the motor 3, and 7 is a general control unit.

せ検索を再開する。Next, the operation of the above configuration will be explained using FIG. 2. When searching the surrounding area, the general control section 7 sends a start signal to the motor drive section 6 and the infrared signal processing section 5.
, the detection unit 11 is rotated by the drive of the motor 3, and the infrared signal is processed, and a surrounding search is started. If there is no intruder 9, sunlight or indirect light from the window 8, or anything that emits radiant heat rays such as an electrical appliance 10 in the surrounding area, the search for the surrounding area continues. Furthermore, if there is something nearby that emits radiant heat rays as described above, the infrared detection section 2 detects this by a sudden change in the amount of radiant heat rays, and the general control section 7
is the motor drive section 6. A stop signal is sent to stop the rotation of the motor 3 and the detection unit 11 is stopped. Immediately after that, a drive signal is sent from the general control unit 7 to the ultrasonic signal processing unit 4 to cause the ultrasonic transmitter/receiver unit 1 to start transmitting and receiving ultrasonic waves, and the ultrasonic ranging method detects the movement of two objects within the detection area. Detect whether it is present or not. That is, by measuring the distance to the object by receiving waves reflected by the ultrasonic waves hitting the object, the movement of the object is detected 17, and it is determined whether or not there is an intruder within the detection area. Furthermore, when the intruder 9 moves, the amount of radiated heat rays in the infrared detection section 2 changes in that direction, so the infrared detection section 2 can also detect the intruder. If it is determined that there is an intruder, the comprehensive control section 7 issues an intruder alarm signal. If it is determined that there is no intruder, the general control unit 7 sends a stop signal to the ultrasonic signal processing unit 4 to stop transmitting and receiving ultrasonic waves, and also sends a start signal to the motor drive unit 6 to detect the intruder. Rotate the section 11 to restart the search.

知部２を併用すれば誤検知は低減される。In the above embodiment, the intruder is detected by the ultrasonic transmitting/receiving section 1 and the infrared detecting section 2 as described above, but if the ultrasonic transmitting/receiving section 1 is used alone, there are moving objects other than humans. If the infrared detection unit 2 is used alone, there is a risk of false detection if the sunlight from the window 8 moves. However, if the ultrasonic transmitter/receiver 1 and the infrared detector 2 are used together, false detections can be reduced.

できる。As described above, in the present invention, the intruder detection section has two detection means with different detection principles, and each detection means can search for an intruder while compensating for each other's weaknesses.
There is no need to lower the sensitivity depending on the environment as in the past, and the reliability of intruder detection is improved. Furthermore, since the detection section can be rotated in all directions, a wide detection area can be obtained, and the number of detection sections and wiring can be simplified.
