た。 In conventional intruder detection systems, detectors are fixedly installed, meaning that a detector is installed at each location where an intruder is expected to pass through. For this reason, many detectors are required and the wiring becomes complicated. In addition, because the detector uses a single detection principle, it always has weaknesses in detection, such as giving out false alarms or not being able to issue an alarm when there is an actual intruder. It was hot.

知部１１を回動させ検索を再開する。 Next, the operation of the above configuration will be explained using FIG. 2. When searching the surroundings, the comprehensive control section 7 controls the motor drive section 6 and the infrared signal processing section 5.
The detection unit 11 is rotated by driving the motor 3, and the infrared signal is processed to start searching the surrounding area. Intruder 9,
Direct or indirect sunlight from window 8 or electrical appliances 10
If there is nothing that emits radiant heat rays, the surrounding search 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 comprehensive control section 7 sends a stop signal to the motor drive section 6. feed, stop the rotation of the motor 3, and detect the detection part 1.
Stop 1. Immediately after that, the general control unit 7 sends a drive signal to the ultrasonic signal processing unit 4 to cause the ultrasonic transmitting/receiving unit 1 to start transmitting and receiving ultrasonic waves, and the ultrasonic ranging method detects whether there is any movement in the object within the detection area. Detect whether or not. That is, the movement of the object is detected by measuring the distance to the object by receiving waves reflected by the ultrasonic waves hitting the object, and determining 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 part 11 to restart the search.
上記実施例では以上のように侵入者の検知を超

部２を併用すれば誤検知は低減される。 In the embodiment described above, the intruder is detected by the ultrasonic transmitting/receiving section 1 and the infrared detecting section 2, but if the ultrasonic transmitting/receiving section 1 is used alone, if there is something moving other than a human being, 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.

There is no need to increase the sensitivity depending on the environment, 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.
