The sentry gun detachment system of military units in Fujian Sentinel Science and Technology Co., Ltd. is based on the recent incidents of attacking sentry, robbing sentry, leaving sentry unauthorized and robbing guns in some military units, taking the world's most advanced radio frequency identification technology, sensing technology, monitoring technology, communication technology, RTLS real-time positioning technology as the background. Security system developed on the basis of technology. The system has the following characteristics: real-time alarm of gun and human departure, event recording, evacuation and defense, tracking and positioning, wide practicability, strong anti-jamming and so on. Now it has been installed and used on mobile and fixed sentry guns in the army. By connecting the "alarm control command center" (duty room), the system achieves timely, accurate, multi-directional and multi-functional alarm effect. The system has the advantages of simple operation, convenient use, reasonable configuration, strong pertinence and stable operation. To the various design functions. The army has been equipped.
1 System Principle
Micro-signal transmitter (gun monitoring label) is installed in the butt of automatic rifles such as "81", "81-1", "95" and "03". According to the actual situation of the guard, the monitoring control range of the system is delimited, that is, the warning line. The signals collected by the receiver are analyzed by single chip computer, and when the guard appears to be off. When the position is 4-5 meters away, the alarm system of gun departure loses the signal of the reading host, the buzzing of the gun monitoring label or the sound-light alarm of the reading host indicate that the gun is abnormally out of position. If the system returns within the prescribed time, it will return to normal. Otherwise, the alarm system will be regarded as the alarm situation of gun stolen and robbed. The alarm gives an alarm. When the alarm host in the duty room receives the alarm signal, the sound and light display the whistle number and send out the alarm sound. The staff on duty may arrange for the disposal of the contingent. In order to understand the whole process of the sentry's duty situation and provide the reference data after the emergencies, the alarm host set up a storage unit to record the gun's detachment comprehensively.
2. System Architecture and Scheme Explanation
Intelligent sentry gun off-position alarm management system is mainly composed of two parts: hardware and software of RFID for gun off-position monitoring.
3.1 Gun Off-position Monitoring Hardware
1. The equipment of RFID monitoring and positioning reading host (also called monitoring host, dual-frequency integrated reader and writer) is divided into 2.45G and 125K. The monitoring host is mainly responsible for the signal sent by the data acquisition label. The equipment can be connected with an audio-visual alarm along the way. The label data can be sent to the back-end server through RJ45 network line or RS485 serial port.
2. RFID gun monitoring label. The anti-theft tag for gun monitoring is 2.4 and 125 K dual-frequency semi-active. The tag sends out 2.4 G signal regularly and receives 125 K activation signal. Label built-in batteries, batteries can be replaced, because the power consumption of the label is low, so a battery labeled by personnel can normally be used for more than two years.
3. Acousto-optic alarm. The RFID monitoring, positioning and reading host can be connected with an audio-visual alarm. The acoustooptic alarm is connected with the monitoring and positioning host through two cores.
4. Network Equipment
5. Computers and Servers
3.2 Software of Gun Off-position Monitoring System
Using cloud computing technology, through the design of cloud computing, a large amount of data processing can be accomplished through multiple servers, which avoids the computational pressure brought by the processing of all data by a single server.
3. Introduction of System Function
1. Low power consumption of equipment: fully responding to the green environmental protection concept advocated by the state, all the system equipment adopts ultra-low power design. It saves energy and prolongs the service life of equipment.
2. Strong anti-interference ability: With the development of society and the improvement of people's living standards, the electromagnetic environment of urban airspace is more complex, such as the widespread application of mobile communications, the increase of the density of high-voltage power grid, and the interference to wireless communications is increasing. In order to ensure the high reliability of the system, the system uses unique coding technology and frequency hopping communication technology to effectively resist electromagnetic interference and avoid false alarm.
3. The system has automatic alarm function after guns leave the post: according to the actual situation of the troops on duty, the system can automatically warn or alarm the duty personnel after the sentry leaves the post without authorization and the illegal elements grab the guns to escape the post.
4. Anti-demolition and anti-destruction: It has the function of anti-demolition and damage alarm. The electronic tag in the gun has the function of anti-demolition. When the electronic tag in the attachment box of the butt is illegally demolished, it can automatically alarm. The equipment has small volume, good concealment and is not easy to be destroyed by human.
5. Various warning functions: in-situ display of guns, out-of-position warning or alarm, power loss warning, multi-level alarm, disconnection alarm.
6. Close to the user's needs, strong practicability: Because the system uses our own know-how and has many years of application development experience, it can improve or adjust the performance indicators of products in time to meet the special needs of users.
4. Introduction of System Software
1. Software interface of intelligent sentry gun off-position alarm management system
2. Display of alarm system and query of historical alarm information
Query the alarm information of gun off-position, including anti-disassembly abnormal alarm information, signal disappearance alarm of off-monitoring area, label low-power information alarm and so on.
3. Label information input and system initialization
For labels, enter relevant data, add gun monitoring labels or delete related labels
5. System Composition and Architecture
The whole system consists of five parts: trigger reader R910, gun monitoring label T095, acoustooptic alarm, gun off-position alarm system software and control computer.
6. Introduction of System Hardware
1. RW-R910 trigger reader
2. RW-T095 Gun Monitoring Label 7. Service Technical Support
If the system fails, the company first unconditionally provides technical support to customers, including telephone technical support and technical personnel to the scene to solve the problem.
_Requirements change If there is a need to modify the software, the company will modify the application module free of charge when the basic software needs remain unchanged.
In the case of extra charges, additional equipment or new functional modules or subsystems need to be added.
