Description

Technical Field

[0001] The present invention relates to the field of security technology, and in particular to an automatic deployment and withdrawal alarm system and method based on microwave and infrared dual detection. Background Art

[0002] With the rapid development of science and technology, security monitoring systems and anti-theft alarm systems play an increasingly important role in modern society. These systems are not only used to protect personal property and life safety, but are also widely used in commercial, industrial and public areas.

[0003] In the existing security monitoring system, there are several major shortcomings:

[0004] a) Limitations of single sensor detection:

[0005] 1) Microwave radar sensor: Although it can detect the movement of objects, it is not sensitive enough to detect stationary humans or small animals and is prone to false alarms.

[0006] 2) Infrared sensor: sensitive to changes in ambient temperature and easily interfered by heat sources, resulting in false alarms.

[0007] 3) Camera: It only relies on image recognition technology and is easily affected by factors such as light and angle, and the recognition accuracy is not high.

[0008] b) Lack of multi-sensor fusion technology:

[0009] Existing systems usually only use a single sensor for detection and lack multi-sensor data fusion technology, resulting in inaccurate and unreliable detection results.

[0010] c) Manual arming and disarming operations are cumbersome:

[0011] Existing systems usually require manual arming and disarming operations, which are cumbersome and error-prone, and cannot achieve automated management.

[0012] d) Lack of intelligent management:

[0013] The existing system lacks intelligent management functions, cannot automatically adjust the security level according to actual conditions, and cannot achieve automatic deployment when no one is around.

[0014] e) Untimely alarm response:

[0015] When the existing system detects unauthorized personnel, the alarm response time is long and the alarm cannot be issued in time, affecting the security monitoring effect.

[0016] In summary, the existing security systems mainly rely on single sensors and manual arming and disarming, but these methods have many limitations, such as slow response, cumbersome and error-prone operation, many false alarms and missed alarms, and untimely arming and disarming. Therefore, it is necessary to improve the intelligence, automation and networking of security systems, and integrate multiple advanced technologies to improve safety and efficiency, so as to achieve more efficient and safe security management. Summary of the invention

[0017] Purpose of the present invention:

[0018] a) Improve detection accuracy and reliability:

[0019] Dual detection is carried out through microwave radar transmission and infrared sensors, combined with multi-sensor data fusion technology to improve the accuracy and reliability of detection and reduce false alarms.

[0020] b) Realize automatic disarming:

[0021] In the armed state, face recognition technology is used to automatically identify authorized personnel entering, and automatically disarm when they are identified as white-listed personnel, reducing manual operations and improving the system's automation level.

[0022] c) Realize automatic deployment:

[0023] Through the intelligent management function, according to the microwave infrared dual detection results, the security level is automatically adjusted when no one is in the room, and automatic deployment is achieved when no one is in the room, thus improving the intelligence level of the system.

[0024] d) Improve alarm accuracy and response speed:

[0025] By optimizing the alarm logic and communication modules, the alarm response speed is improved to ensure that an alarm can be issued in time when unauthorized entry or intrusion by other means is detected in the armed state.

[0026] The purpose of the invention of the automatic arming and disarming system for human presence detection based on microwave and infrared dual identification is to improve detection accuracy and reliability, automation and intelligence, improve user experience, and adapt to various application scenarios through comprehensive judgment of multiple sets of microwave radars and infrared sensors, thereby providing users with more intelligent, efficient and reliable security solutions.

The monitoring center is connected to the central switch via a network cable, and the central switch is connected to multiple control terminals in the terminal control layer via network cables.

[0172] b) Terminal control layer: The terminal control layer consists of multiple control terminals. Each control terminal is connected to the central switch via a network cable. At the same time, the control terminal is connected to the terminal switch of the data transmission layer via a network cable.

[0173] c) Data transmission layer: The data transmission layer consists of terminal switches and intelligent gateway serial port servers. The terminal switches are connected to the control terminals of the terminal control layer through network cables, and are also connected to multiple intelligent gateway serial port servers through network cables. The intelligent gateway serial port servers are connected to the terminal switches through network cables, and are also connected to the microwave radar sensors, infrared sensors, sound alarms, light alarms, access card readers and face recognition of the perception layer through RS485 cables.

[0174] d) Perception layer: The perception layer consists of human detection sensors, alarms, and personnel identifiers.
