I think everyone has seen the curtain door, generally more or less some of the function of theft, a lot of people understand it very well, the main role played by the anti-theft special curtain door is to prevent thieves from invading, so the bank set up this kind of curtain door is inevitable. So how does a bank curtain door work, you know?
The position sensing system is located on the inside of the door body of the curtain and is connected with the post of the door body. The outdoor alarm device is connected to the outside of the door post, and the indoor alarm device is connected to the inner wall of the room. Because the indoor alarm device and the outdoor alarm device are composed of an alarm light and a buzzer, the distance from the inside of the door body is the set sensing distance, and the output is connected to the input of the alarm control system. Through the position sensing sensor installed inside the door body of the curtain door body, when the door body is shaken by touching the door blade, when the door body jitter exceeds the set sensing distance, the position sensing system is blocked, thereby sending the position sensing information to the alarm control system., The output of the alarm control system is connected to the alarm device. After receiving the position sensing information sent by the position sensing system, the driver alarm device reaches the alarm. If the thief hears the alarm and runs away, or if the police officer hears the alarm, he will quickly reach the place where the alarm is issued.
Note: 1. sensors can be implemented using infrared sensors;
2, alarm control system can be implemented by single chip microcomputer or chip system;
3, alarm devices include: indoor alarm devices and outdoor alarm devices;
Conclusion: This design of the theft state sensing greatly improves the anti-theft performance and the availability of anti-theft devices
