I think everyone has curtain doors. There are some anti-theft functions. Many people know that the main function of anti-theft shutters is to prevent burglars from intruding, because these shutters are set up in banks. So how does the curtain door of the bank guard against theft, do you know? In fact, it's very simple, let's understand it together!
The position sensing system is located in the inner side of the curtain door body, and is fixedly connected with the door post. The outdoor alarm device is fixedly connected with the outside of the door post, and the indoor alarm device is fixedly connected with the indoor side. Because the indoor alarm device and the outdoor alarm device are composed of alarm lamp and buzzer, the distance between inside and outside of the door will be set as induction distance, and the output end is connected with the input end of the alarm control system.
The position sensor is set in the body of the anti-theft safety shutter. When the body of the door jitters due to the contact with the door, the body jitter amplitude of the door is set by the induction distance, the fuzzy position sensor system and the position sensor alarm control system. The output of the alarm control system is connected to the alarm device, and when the receiving position sensor system. Send position sensor information, drive alarm device to alarm, let you send out alarm and escape, otherwise the police will hear the alarm and arrive at the alarm faster.
1. The position sensor is realized by infrared sensor.
2. The alarm control system can be realized by single-chip computer or on-chip system.
3. Alarm devices include: indoor alarm devices and outdoor alarm devices;
