Realizing wireless firearm departure alarm based on rfid uwb ranging technology

Firearms are a special Tool to deter crime. In order to strengthen the security of the troops and prevent the occurrence of firearms on duty being robbed, sentries being attacked and sentries fleeing the troops with guns, the supervision and management of guns on duty should be strengthened to effectively prevent weapons Equipment is lost and vandalized, preventing major and malignant cases involving guns and bombs from occurring, and maintaining social stability.

Using rfid uwb ranging technology to realize wireless firearms out of position alarm, the installation is simple, the performance is stable, the false alarm rate is low, and the work is reliable. It plays an important role in the security of military sentry gun management, and has been well received by many troops.

The gun departure alarm system consists of four parts: the rfid electronic tag installed inside the gun; the distance controller; the alarm controller and the central alarm terminal equipment.

The electronic tag is installed in the duty gun accessory box, the alarm controller is installed at the duty post (post), and the central alarm receiving terminal equipment is installed in the door duty room to receive alarms.

3. Main system features

The working principle of the gun out-of-position alarm system is mainly that the electronic tag continuously emits a specific alarm signal to the alarm controller. When the gun is within the effective range, the alarm will not alarm. When the system cannot receive the handshake signal, (this distance is adjustable) When the alarm controller fails to receive the signal, the controller immediately reminds the guards to return to their posts through voice. At the same time, the alarm controller sends an alarm signal to the duty room. The personnel on duty immediately take relevant measures to deal with the alarm after receiving the alarm signal.

This system uses fully wireless encrypted communication technology, and the communication between its main equipment, RFID electronic tags, alarm controllers, and central alarm terminals, is all wireless encrypted communication. The system is flexible and easy to install, which not only makes up for the shortcomings of wired communication, but also overcomes the system's false alarm rate and failure rate, as well as the installation and maintenance workload. This system mainly has the following advantages:

---The device has low power consumption. All system equipment adopts ultra-low power consumption design. Save energy and extend service life.

---Strong anti-interference ability. This system adopts the most advanced frequency modulation technology and spread spectrum communication technology, which effectively resists electromagnetic interference, avoids false alarms, missed alarms, delayed alarms, and delayed alarms in the system, and greatly enhances the reliability of system equipment. .

---Multiple police situation handling functions. This system has multiple alarm methods such as gun removal alarm, emergency alarm, man-made sabotage alarm, remote control alarm, etc.

System advantages******************************************
