In order to strengthen military security , to prevent firearms and ammunition looted duty occurred Sentinel Sentinel carrying bullets were attacked and fled the army , etc. , increase the duty (current ) supervision and management of bullets , bullets effectively prevent the loss , to prevent firearm- involved playing a major malignant cases occurred , combined with the military reality, we have developed a "firearm anti lost snatches , anti-theft wireless alarm system", " bullet combination bullets isolated wireless alarm system ."
Firearms off-site alarm system
In the " Type 81 ", " 81-1 " type , " the 95 " "03 " type automatic rifle butts and other features miniature signal transmitter , mounted on a rifle , according to the actual situation sentry , monitoring and control systems delineated that range cordon signal receiver collected by the microcontroller analyzed off-site when the sentry appeared 4-5 meters away from the place , the receiver loses the signal , voice prompts from firearms abnormal position, if returned within the specified time, the system returns to normal ; otherwise the alarm system will be deemed to be stealing firearms of police intelligence, by comparison confirmed alarm alarm. ( If you encounter an emergency situation , you can also alarm button alarm . ) After the duty room alarm host receives an alarm signal , sound and light show sentinel number and a voice message and alarm sounds. Duty officer can arrange emergency unit for disposal. In order to understand the situation sentry on duty the whole process , as well as providing information for future reference after the incident occurred , the police set up a storage unit host of firearms from the position to conduct a comprehensive record.
Second, the system components
1 UHF RFID electronic tags
As the most advanced electronic tag identification code , and it has not damaged , reliable data, use that as uniquely identifies the target tracking and positioning. Work , management staff through networking wireless base stations to track and identify long- positioning period , the effective communication distance and other characteristics , is an alternative to bar codes, the best choice for infrared identification . It is installed on the target object to be controlled .
2 UHF UHF RFID reader
UHF RFID reader controller , a microprocessor, a security module and microwave communications controller and RS232, 485, TCP / IP and other communication interface components to wireless short-range communication protocols and microwave transmission means , the implementation and the UHF RFID secure and reliable exchange of information between the purpose , RWU via RS232, 485, WIFI, GPRS, TCP / IP , etc. connected to the host computer , control commands received from the host computer and the data and return data.
3 LF activator
4 or 6-channel activation antenna adjacent four or six rooms can share a low frequency activator throughout our positioning system to locate the base station is the smallest basis points , as the anchor point nearest the starting point , which activating the tag from 3-3.5 m is in the range of each label is activated activator 3-3.5 meters , the positioning accuracy can be described as 3-3.5 meters. Activator different regions , has its own unique address code , when a person with a semi-active tag enters a low frequency activation positioning base station is activated, the label is working properly, send tag's ID number to the outside world , but also sent the activation tag activator address code , so that by activating the address code , we can locate the position of the label is located. When the label to get from one location to another activator , upload up activation code will also change the address , so that it formed a complete positioning system. Update the tag data is received by the base station positioned within the gateway to a wide range , the information is uploaded to the management center for treatment , completed the positioning system. Outpost off-site system , simply activate the low-frequency device or reasonable arrangement can effectively control the outpost way through the coil beltway around five meters away from the place .
UHF RFID firearms off-site alarm system
Third, the system features
1 robbery of firearms with real-time automatic alarm function: The device has advanced detection capabilities , real-time operation in 24 hours monitoring and control for firearms or firearm robbed bit off automatic alarm notification duty .
2 for unauthorized absence from sentinel with automatic alarm : The system for the actual situation of the army sentry duty , sentry against unauthorized leave their posts , the system can automatically alert or alarm notification duty .
(3) removal of anti- vandal : a demolition destroy tamper alarm function . Electronic label inside with anti- demolition firearms function, when the illegal removal of the tag set in the butt accessory tray , automatic alarm . Devices are small, hidden, and easy to vandalism.
4 multiple alarm functions: firearms reign showed off bits warning or alarm , power failure prompted an emergency alarm, multi-level alarm, break alarm .
5 has a real-time event logging function : The system can perform real-time detection of sentinel duty , to events in real-time recording and easy access to relevant personnel afterwards .
6 arm disarm : arm and disarm can be set period of time based on rotations .
7 anti-interference ability : the use of radio-frequency three- hopping technology , adaptive space radio waves.
8 all-wireless mode , low power consumption : energy saving, low power consumption. Field testing equipment are low power devices ;
9 new design ideas . The project is a comprehensive analysis of the key and difficult problems of military duty work , review the alarm , alarm linkage has done a systematic study , creatively put forward the combination of air defense and anti-technology , anti- foreign and anti- combined with the design ideas from fundamental solution to the long-standing military duty firearms easily control problems. Meanwhile, with a wide range of applications in military equipment supervision, personnel monitoring and other related work, to fill the gaps in the field.
10 Adaptability : The system features a modular structure , capable of firearms from the position according to actual needs , Sentinel off-site , emergency alarm functions for flexible combinations , with a wide range of adaptability.
11 Track Positioning : Once there are special circumstances , people can listen to the sound track of guns around by phone or via SMS to know the geographical location of firearms from the position . Meanwhile you can find real-time geographic location of firearms by phone or computer online platform " position online " electronic map.
12 bullets separation, bullets combined : Sentry guns and long guns and magazine clip isolated or combined , the system will send an alarm immediately , greatly improving the army sentry emergencies disposal rapid response capability , improved security management sentinel level.
An army battalion -level units using UHF RFID Management firearms
Army units in the main work area , focusing on prevention area, reservoir , camp sites and equipment import and export channels , such as " electronic test " or "UHF RFID automatic identification " system and network connections in the system , so that with the passage of automatic identification , access to real-time recording , access authorization , illegal access to the police, information query functions , data analysis , strengthening the confidentiality , security, security work to ensure the safety of weapons and ammunition , equipment and vital sector ; for real-time , accurate and complete grasp of military people , vehicles, objects , raising the effectiveness of the military and scientific management , enhance military deterrence , both will play a positive role.
