1. System introduction
Police guns are a special tool to deter crime, so the management of police guns is particularly important. The management of police guns refers to the effective monitoring and management of guns in the storage, warehousing, transportation, use, carrying, and return. If the supervision is not in place, it will bring major security risks to the country and society.
This system uses RFID technology to be applied to the management of armed police guns, and uses the RFID gun monitoring cabinet to monitor the number and number of the guns in the cabinet in real time. It does manage all the links of the police before, during, during, and in use of the guns, and report the abnormal status of the guns to the system monitoring center in real time.
This system is an automatic identification technology, a scientific and technological means that can effectively monitor the expenditure of guns online, and is an effective tool for tracking management and statistical management.
2. Problems that this system can solve
1. Provide a strict and convenient gun acquisition management mechanism
2. The management personnel can grasp the status of the guns in real time, and realize the management method of transparent information
3. Solve the hidden safety hazards caused by human factors
4. Prevent the occurrence of misconduct by technical means
3. This system includes the following parts:
1. Real-time monitoring and management of gun warehouses
2. The guns were taken out of the monitoring and management of the duty post
3. Management of guns being taken out of shooting range
(1) RFID electronic tags for guns
1. Gun RFID electronic tags use 2.4G active electronic tags, each tag is assigned a unique ID number, and the gun’s number, model, production date and other information are associated in the system
2. The RFID electronic tag of the gun is bound to the gun using a keychain to prevent the electronic tag from being abnormally separated from the gun or the anti-disassembly electronic tag is pasted on the gun with 3M glue. Once it is not authorized for mandatory removal, an alarm will occur
Gun RFID electronic tags use 2.4G active electronic tags, each tag is assigned a unique ID number, and the gun’s number, model, production date and other information are associated in the system
The gun RFID electronic tag is bound to the gun using an electronic lock to prevent the electronic tag from being abnormally separated from the gun
(2) The approval process for gun acquisition
1. When a police officer (assignment personnel identification card) needs to obtain a gun, apply for the gun model in the system
2. After the police officer reviews the application, the system assigns the corresponding guns, and the guns are marked as available for use in the system
3. Police officers swipe their identification cards to enter the gun storeroom to obtain the corresponding guns, unauthorized officers or guns that do not correspond to the guns cannot get the corresponding guns.
4. Monitoring and management of guns at duty posts
1. RFID receiver communication
The online CMC191 device has a’heartbeat’ mechanism, that is, after the computer is successfully connected to the CMC191 network, the CMC191 will send a heartbeat packet to the computer every two seconds. If the computer does not receive a heartbeat packet for more than 3 seconds, an alarm will be triggered.
2. Real-time notification of system status by each system branch and system center
Each system branch sends its own system running status to the remote system center in real time, and the system center determines whether the current branch system is normal, otherwise an alarm is triggered.
