RFID is a flexible application technology that is easy to control, simple and practical, and especially suitable for automatic control. The identification work does not require manual intervention. It can support both read-only working mode and read-write working mode without contact or aiming; Can work freely in a variety of harsh environments: short-distance radio frequency products are not afraid of oil stains, dust pollution and other harsh environments, and can replace bar codes, such as tracking objects on the assembly line of a factory; long-distance radio frequency products are mostly used in traffic, and the identification distance can be Up to a few meters, such as automatic toll collection or vehicle identification. Its unique advantages are beyond the reach of other identification technologies, mainly in the following aspects:
1. Convenient and fast reading: Data reading does not require a light source, and can even be carried out through the outer packaging. The effective recognition distance is larger, and the effective recognition distance can reach several meters;
2. Fast recognition speed: as soon as the terminal enters the magnetic field, the reader can read the information in it instantly, and it can process multiple terminals at the same time to realize batch recognition;
3. Large data capacity: The two-dimensional barcode (PDF417) with the largest data capacity can only store 2725 numbers at most; if it contains letters, the storage capacity will be less; RFID electronic tags can be expanded to dozens according to the needs of users K;
4. Long service life and wide range of applications: its radio communication method enables workers to work without being in high pollution and radioactive environments such as dust and oil. The closed packaging of the terminal makes the service life much longer than the printed bar code;
5. The label data can be changed dynamically: the data can be written by the programmer, which gives the RFID label interactive portable data file function, and the writing time is less than that of printing a bar code;
6. Better security: Not only can it be embedded or attached to products of different shapes and types, but also password protection can be set for the reading and writing of terminal data, thus having higher security;
7. Dynamic real-time communication: The electronic tag communicates with the reader at a frequency of 50-100 times per second, so as long as the object attached to the RFID electronic tag appears within the effective recognition range of the reader, its position can be dynamically determined Tracking and monitoring.
System solutions
2.1 Introduction to system functions
The RFID firearm management system can automatically record the gun number and display the presence of the gun, automatically record the entry and exit of the firearm and the status of the gun holder, automatically record the inventory of the firearm and ammunition, automatically print the entry and exit list of the firearm and ammunition, and the firearm Archives, ammunition receipt and payment ledger, gun holder files, etc. All information related to guns and ammunition is recorded and stored in the computer, which can be queried and printed at any time, completely replacing the original method of recording and signing with a pen; the real-time monitoring and alarm system can monitor the door of the gun library, the gun lock, and the ammunition cabinet. The cabinet door and the guns in the warehouse are monitored, and the illegal opening of the door and the removal of the guns are reported and recorded.
1. Develop a weapon use plan: A weapon use plan formulated for a certain task or for a certain purpose. Each time a weapon support plan is formulated, a weapon support plan document will be formed. The weapon support plan being implemented can monitor the dynamic information of the number of weapons borrowed and returned by each brigade.
2. Weapon entry and exit management: by allocating to firearm users, using the combination of the RFID electronic tags installed on the gun body and the RFID reader in the gun warehouse, it can be used for gun management personnel, gun holders and supervisors. The leader conducts identity identification, automatically controls the opening of the gun and ammunition warehouse door, gun cabinet lock, and ammunition cabinet door, and automatically records and displays the presence of the gun, automatically records the entry and exit of the gun and the status of the gun holder, and automatically records the gun And ammunition inventory, automatic printing of guns and ammunition entry and exit tables, gun files, ammunition receipt and payment ledger, and gun holder files, etc.
3. Weapon maintenance and management: Through the handheld RFID reader, among a large number of firearms, the firearms that need maintenance and maintenance can be identified, and the maintenance personnel, maintenance time, maintenance content and other file information can be recorded, and finally archived and stored .
4. Weapon scrap alarm: use the large-capacity data storage function of RFID electronic tags to record weapon service life information. When the service life of the weapon drops to a certain period, the RFID reader can be used to find and remind the weapon management personnel. Weapons are processed.
