1. Background Introduction
1.1. System application background
With the rapid improvement of the global informatization level, it is particularly important to further strengthen the information management of the troops, improve the security measures of the troops, ensure the safety of the troops, and improve the combat effectiveness of the troops. At present, some criminals use fake military vehicles, fake license plates, and false witnesses to commit crimes and various sabotage activities. There are also occasional reports of personnel on duty in military barracks running off guards; they go out privately without asking for instructions. , It is not uncommon to drive privately to violate military discipline. In this regard, many troops have begun to strengthen the information management of confidentiality, security, and personnel, vehicles, and materials, and this has been taken as an important measure to ensure the safety of the troops and improve the combat effectiveness of the troops. In response to the above-mentioned problems in the current army, we believe that the focus of information construction is to improve the “soft” combat capabilities of the army, and establish an information management with multiple functions such as early warning, command, control, protection, and support as the main goal. Must do.
If all units of the army are equipped with “electronic detection” or “automatic identification” systems in the main work area, key defense area, storage area, barracks entrance and exit passages, etc., and realize the network connection in the system, so that it has automatic identification, access and exit Real-time recording, authorized passage, illegal entry and exit alarm, information query, data analysis and other functions are useful for strengthening confidentiality, security, and security, ensuring the safety of weapons, ammunition, equipment, and key departments; for real-time, accurate and complete control of the troops The situation of people, vehicles, and objects will play a positive role in improving the effectiveness of scientific management of the troops and enhancing the deterrence of the troops.
As the future direction of the military’s efforts, informatization construction, regardless of which branch it belongs to, has included the development and utilization of information resources as the core informatization construction work on the agenda of military construction. Therefore, Beijing Guanlin Co., Ltd. took the lead in adopting RFID technology in the country, and organically combined long-distance radio frequency identification technology with information technology, data communication transmission technology, electronic control technology and computer processing technology to develop the “Automatic Vehicle Identification Management System for Troops”, ” “Military Vehicle Inspection Management System”, “Military Supplies Entry and Exit Supervision System”, “Sentinel (Guns) Displacement Alarm System”, “Personnel Automatic Identification Management System”, etc. The application requirements of the troops in the following aspects are solved:
(1) The product is a self-developed domestic high-tech product with independent intellectual property rights and its own technical standard system, which fills the domestic gap and has no technical safety hazards.
(2) The product can adapt to various installation and use environments.
(3) The product can identify multiple targets at the same time, which is especially suitable for the management of personnel, vehicles and logistics materials in and out of the army.
(4) There is no harm to human body caused by electromagnetic pollution.
(5) System products have become “super-intelligent”, with extremely low technical requirements for users, and have realized simple and adjustable functions.
(6) The performance is stable, the price is cheap, and it is convenient to connect to the network in the system.
(7) Technical support is convenient and fast.
The realization of the above-mentioned technological products will surely have a profound impact on the military’s informatization construction and the strategic goal of “strengthening the army with science and technology.”
2. Product features and system superiority
2.1. The radio frequency identification card is tailor-made for Type 95 rifles: The active tag in the firearm out-of-position alarm system designed by our company is the same size as the auxiliary product compartment of the actual Type 95 automatic rifle, which can be easily installed or removed.
2.2. Radio frequency identification card anti-disassembly alarm: in the case of arming, if someone takes out the active identification card in the secondary product warehouse, the alarm system will be activated to release the disassembly.
2.3. Optimized anti-false alarm system: This system optimizes the entire system according to actual site needs, with infrared triggers, delay relays, etc., so as to prevent false alarms at ordinary times, and promptly alarm when there is a situation (guns are out of position).
2.4. Adjustable alarm time and alarm distance: Due to the unique design of the card reader, the RF power is adjustable, so that the alarm distance can be adjusted on site.
2.4. Standard Wiegand26 data upload function: connect to Wiegand controller to realize gate opening,
3. Product system composition
3.1. Card reader: The 2.45g active directional card reader independently developed and produced by our company (see the directional card reader manual for specific parameters), which plays the role of “monitoring” guns in this system.

4. Backstage management software and system functions
The main function of the software is to implement alarms and set alarm conditions in conjunction with the alarm system. In addition, it can monitor the operation status of the guard box in real time.
Five, equipment installation
2. The 45G long-distance card reader chooses top-mounted installation according to the sentry box environment (receive label data downward);
The alarm is installed in the area (control room) where the alarm needs to be notified, using AC 220V or DC12V power supply;
The label is installed on the butt of the gun (it can be changed according to the model of the gun).
Five, software process
If the above products still cannot meet your needs, then we can provide product development and customization services. The specific process is as follows:
A) Customer’s request
B) We propose solutions, as well as development cycle, customization costs, etc.
C) Submit samples and software for user testing
