PIR PIR Motion Detection Sensor and Safety Sensor and Automatic Door System using the PIR Motion Sensor

摘要

The present invention utilizes a pyroelectric infrared (PIR) sensor (3), a novel sensing consisting of a Fresnel lens (2), a signal amplifier (4), a motion determination unit (5) and a lens window (6) It relates to a pyroelectric (PIR) motion detection sensor 30 that can be adjusted freely by introducing the area adjusting unit (1). As an example of the application of the motion sensor, the scope of application is expanded to the safety sensor and the upper sensor of the automatic door system including the screen door. When the door 12 is closed in an automatic door, a person, an animal, or an object in an area in which the door 12 moves in a state where the door 12 is not completely closed or in a safety sensor detection area 17 in which the door may be moved may feel a danger. When the movement of the detection of the pyroelectric infrared (PIR) safety sensor (7) to inform the automatic troubleshooter 18 of the movement and the automatic door system having the same. By using pyroelectric infrared (PIR) sensor (3), there is no malfunction in sunlight or illumination light, and it can detect a large sensing area, so safe automatic door operation is possible. . In addition, by introducing the detection area adjusting unit 1 composed of the lens window 6, the safety sensor detection area 17 can be freely adjusted, and can be customized to various places. The advantages of the safety sensor also apply to the upper sensor.
