Foreword Foreword
Informatization construction is the direction of future military efforts. Regardless of the branch of the military, the development and utilization of information resources as the core information construction work has been included in the military construction agenda.In order to improve the combat effectiveness of the public security organs and security departments, strengthen the management of firearms and ammunition, ensure the safety of firearms and sentries on duty, maintain the security and stability of the army and society, ensure that the people’s police and security cadres use firearms correctly in accordance with the law to perform their tasks, and fully implement the “Zhonghua People’s Republic of the People’s Republic ofRFIDGun management system.
If all units of the department are equipped with “electronic monitoring” or “automatic identification” systems in the main work area, key prevention area, storage area, barracks entrance and exit passages, etc., and realize the network connection in the system, so that it has automatic communication identification, entry and exit Realize multiple functions such as recording, authorized passage, illegal entry and exit alarm, information query, data analysis and so on. It will play a positive role in strengthening secrecy, security, and security, ensuring the safety of weapons, ammunition, equipment, and key departments; in real-time, accurate, and complete grasp of the effectiveness of the scientific management of the army, and in enhancing the deterrence of the army.
System Overview System Overview
The on-duty firearms off-position alarm tracking and positioning system can record real-time alarm and video recording of emergencies such as attacking and looting the guard post and leaving the guard post without authorization; it can accurately locate the robbed, lost or hidden guns, and visually display the trajectory and location of the guns; it can accurately detect Identify the location of guns or robbed guns, guide the emergency team to deal with them effectively, and solve the problem of preventing dynamic gun hang-up.
The overall plan uses RFID technology as the basic support technology, combined with GPS positioning technology and GPRS packet wireless business technology, to conduct real-time management of on-duty personnel, and accurately locate robbed, lost or concealed guns.
Once the personnel on duty leave the guard post during the on-duty period, the positioning signal generated by the RFID positioning device will be lost. It is judged that they leave the guard post without authorization during the on-duty period, and this information is fed back to the command center through the network.
The firearms have built-in GPS and GPRS modules. When the firearms are robbed, lost or concealed, the emergency team can track the position of the firearms according to the GPS positioning module; the GPS and GPRS modules in the firearms can feed back the position to the command center and tracking terminal.
System Architecture Diagram System Architecture
The sentry gun in the picture is embedded with the gun tag, and the tag status information is continuously sent to the reader under the positioning excitation of the positioning reader. The reader transmits the tag status information to the converter through the 485 bus, and the data is transmitted to the PC software via the Ethernet Data analysis is carried out in the process. Once the firearm is out of position, the PC software immediately triggers the alarm and controls the alarm to send out sound and light alarms. At the same time, the software adjusts the field alarm video for verification. The whole process enables the sentry on guard status to be intelligently supervised and guaranteed Alarm events are identified in time, proactively and intelligently, and controlled in time. Global positioning and tracking of the gun location is carried out to facilitate the rapid retrieval of the gun.
System Components System Components
RFID active tag
It is installed in the gun and communicates with the RFID reader.
Reader
Responsible for transmitting alarm data and positioning data to the background server.
Locator
Using low-frequency wake-up technology, it can accurately locate the position of the RFID tag.
Wireless network transmission
The system can support various data information based on mobile network operators’ 2.5G (GPRS/CDMA/EDGE) network and WLAN (wireless local area network) transmission of various data signals such as video and audio signals, and realize remote centralized management and unified scheduling.
System Functions
The firearms off-site alarm tracking and positioning system on duty will improve the existing management in the following aspects and reduce the burden on personnel:
Once the sentry is attacked, the gun is fired, or the sentry is left without authorization, the system will report to the monitoring room and the emergency team as soon as possible to accurately respond to the situation on the spot and facilitate the command to respond in the first time.
