Background technique

The anti-theft alarm system uses physical methods or electronic technology to automatically detect intrusions in the armed monitoring area, generates an alarm signal, and prompts the person on duty to the area where the alarm occurs, and displays possible countermeasures. The anti-theft alarm system is a system that prevents robberies. Important facilities for accidents such as theft and theft. Once an emergency occurs, the location of the incident can be accurately displayed in the security control center through sound and light alarm signals, so emergency measures can be taken quickly, such as anti-theft alarm systems, entrance and exit control systems, closed-circuit television monitoring systems, The visitor intercom system and electronic patrol system together constitute a security system.

The most important existing channel for police help is the 110 police call for help. To complete the 110 call for help, three elements must be clearly stated: 1. Who am I? 2. Where am I? 3. What dangers are encountered? And to explain It takes at least three to four minutes to understand these three problems. However, when we encounter emergency danger, we have no response time or only a very short response time. It is impossible to have three to four minutes to complete the call for help. This creates a contradiction. When encountering danger, there is no time to call the police for help, but it takes enough time to complete the call for help. Moreover, the existing 110 alarm method still has the problem of poor anti-interference, which leads to A large number of people are unable to call the police for help when they encounter danger, resulting in irreparable consequences.
