Thirdly, equipment installation and use

As shown in fig. 9, when the device is mounted to the body 8, the first fixing piece 3, the first fixing piece screw 6, the second fixing piece 4, and the second fixing piece screw 7 are first removed, and the device is slid along the body tactical rail 8-1 in the mounting direction shown in the drawing until the tail end of the device contacts the trigger guard 8-2 (fig. 9 (two)). A first fixing sheet 3 is arranged, and a spare anti-disassembly contact interface 1-2 (fig. 9 (two) - (three)) is accurately attached to the anti-disassembly salient point 3-4 in a pressing mode, so that the normal anti-disassembly detection function is ensured; the left guide rail matching block 1-4 and the right guide rail matching block 3-1 on the two sides of the equipment are combined with the tactical guide rail 8-1 in place, so that the longitudinal stability of the equipment is ensured (fig. 9 (two) - (three)); the transverse slot matching block 3-2 is combined with the guide rail transverse slot 8-3 in place to ensure the transverse stability of the equipment (fig. 9 (two) - (three)). A screw 6 of the fixing piece is inserted through a screw hole 3-5 of the first fixing piece 3 and locked at a screw hole 1-5 of the fixing piece of the upper shell 1 of the equipment (fig. 9 (two) - (four)).

The gun positioner is used for positioning and controlling gun and weapon equipment, and is firmly and inseparably combined with a target gun to achieve the control effect that the device is the gun, the gun is the device, and the gun is fused with a digital platform through the device. Preferably, the present invention is attached to the original structure of the firearm, and the equipment is firmly locked on the firearm by the double-point fixing mode of the first fixing plate 3 and the second fixing plate 4 and the bidirectional fixing structure of the first fixing plate 3, so that the normal use of the firearm is not affected while the effective operation of the equipment is ensured.

The difficulty of the gun positioner lies in how to adapt to the characteristics of compact structure and high use requirement of the gun, designs equipment matched with the structure of the gun, and completes the functions of more complex gun identity recognition, accompanying monitoring, satellite positioning, mobile communication and the like. This requires the inner structure of the locator to be exquisite, the fit to be tight, and the external connection mechanism to the gun to be secure and reliable, which will not affect the normal use of the gun.

Starting from the external structure of the equipment, the external-hanging type gun positioner 200 is hung on the gun body non-movable mechanism through the anti-disassembly mechanism by adopting a fitting type hanging mode, so that the normal use of the gun is not influenced; the external dimension and the structure of the equipment are determined by the mounting structure, and then the design optimization is carried out aiming at the internal structure. Because the internal space is limited, the invention adopts a plurality of technical means to achieve the purpose of reducing the volume of the equipment. In the aspect of a circuit, preferably, the invention does not adopt a common single-board circuit design, but adopts a split modular design according to the requirement of the internal structure of the equipment, and parts such as power supply control, anti-disassembly detection, charging, data communication, a status indicator lamp, each antenna and the like are separated from a main circuit board, so that each component can fully utilize the irregular space in the shell. In terms of structure, preferably, a design mode of longitudinal layering and transverse surrounding is adopted, components irrelevant to radio frequency are divided into four layers in an internal space to be arranged according to the size and the electrical characteristics of each component, and the internal space is fully utilized; radio frequency components such as antenna, RFID chip distribute in the casing periphery, guarantee the compactness of inside overall arrangement on the basis of keeping mutual noninterference between the antenna signal, optimize inside and walk the line overall arrangement simultaneously to reach the organic combination of practicality and reliability.

Fourth, device function and application

The external-hanging gun positioner has to provide the functions of gun identity recognition, accompanying monitoring, gun positioning, anti-dismantling detection, data encryption, automatic energy conservation and the like, wherein the gun identity recognition is realized through an independent RFID passive chip, and other functions are realized through a circuit system. As shown in fig. 10, the circuit portion of the device is divided into several parts in a modular manner based on the MCU 112 as a core and the functional requirements of the device.

1. The positioning module 107: for implementing the satellite positioning function of the device. The device processes radio frequency signals received by a positioning antenna medium 101, and obtains the longitude and latitude of the device in the Beidou positioning system after GNSS settlement. In order to eliminate signal interference, a positioning filter/amplifier 104 is designed between the positioning module 107 and the positioning antenna medium 101, and transmits the radio frequency signal to the positioning module 107 after being subjected to filtering processing and signal amplification. The positioning module 107 sends the calculated longitude and latitude, speed, heading and other information to the control program 112-1 in the MCU 112 for processing, and receives the command and configuration information of the control program 112-1.

2. The Bluetooth module 108: for implementing the matching function with the accompanying monitoring device 201. The Bluetooth BLE4.0/BLE5.0 low-power-consumption protocol is adopted, and the cruising ability of more than 6 months can be provided by one-time charging. The bluetooth module 108 interacts with a control program 112-1 in the MCU 112 to realize the monitoring of the gun and police for leaving the body, and the monitoring of the gun and vehicle for leaving the body and alarming. The bluetooth filter/amplifier 105 is used to eliminate signal interference from the bluetooth antenna medium 102.

3. The communication module 109: for implementing the interaction function with the central server 202. The NB-IOT/LTE CAT1 communication standard is adopted, and the communication environment adaptability of the equipment is improved. The communication module 109 interacts with a control program 112-1 in the MCU 112 to realize the reporting of the gun position, the state and the alarm information and the issuing of the equipment parameters. The communication filter/amplifier 106 is used to cancel signal interference from the communication antenna medium 103.

4. Patch SIM card 110: for accessing a mobile communications network. The common gun positioning device scheme usually adopts a plug-in SIM card, and the disadvantage of the method is that the occupied space is large and the loosening is easy. The gun positioning equipment has higher requirement on space compactness, the gun body vibrates violently when the gun is opened, and the plug-in SIM card is obviously not suitable any more. Preferably, the patch type SIM card which is smaller in size and is connected in a welding mode is adopted, so that the reliability and the effectiveness of the gun positioning equipment are improved.

5. The encryption chip 111: for securing data transmission with the central server 202. The common gun positioning equipment scheme usually adopts a software encryption mode of algorithm encryption, and the defects of the mode are that the implementation mode is not standard, the key protection is not thorough, and the potential safety hazard is greater. Preferably, the invention adopts a hardware encryption chip conforming to the national password standard and a built-in SM series algorithm to encrypt data, and ensures the safety of gun sensitive information transmission by matching with a VPN virtual private channel.

6. The indicator light 113: the device is used for prompting the running state of the equipment and can respectively indicate the working states of communication, positioning and power supply.

7. Removal detection 114: for detecting whether the device is properly loaded with the target firearm. When the device is detached from the firearm, the removal detection 114 module notifies the control program 112-1 at a first time, and the control program 112-1 sends an alarm message to the central server 202 through the communication module 109.

8. Motion detection 115: the device is used for detecting the motion state and the behavior of the device and automatically saving energy when the device is static. In a common gun positioning device scheme, whether the device is in a static state is usually judged only through a vibration sensor, a gyroscope or an accelerometer, and a satellite positioning function is automatically turned off to save power consumption. This approach does not take into account the effects of human micromotion and vehicle engine vibration when the device is attached to a person or vehicle, in which case the device detects the vibration and is in locate mode even though the person or vehicle has stopped moving. Preferably, the invention adopts a behavior recognition algorithm to analyze the data input by the sensor, recognizes and filters the micromotion condition when the personnel and the vehicle are in the static state in situ, and automatically closes the satellite positioning module, thereby improving the application effect of static automatic energy saving.

9. The power supply module 116: and is in butt joint with the lithium battery 117 to provide power management and charging protection functions for the equipment.

10. The cache module 112-2: for buffering the location information when the communication signal is bad. The gun using environment is complex, in a common gun positioning device scheme, a main control program directly sends position information to a server after obtaining the position information from a positioning module, the signal coverage condition of a current mobile network is not considered, and if the signal is poor, the position can be lost. Preferably, the present invention sets a buffer module 112-2 in the MCU 112 program for storing the location point of failure in transmitting the mobile signal to the central server 202 when the mobile signal is bad, and retransmitting the mobile signal when the mobile signal is recovered, so as to ensure the integrity and authenticity of the track.

As shown in fig. 11, during the in-service use, the external-hanging gun locator 200 matches with the accompanying monitoring device 201 of police officer or police car through the bluetooth, and gun is normal when the locator is in monitoring device bluetooth detection range, and when the locator surpassed monitoring device bluetooth detection range, gun off-post warning takes place. At this time, the following monitoring device 201 sends the alarm to the central server 202 located in the central machine room through the communication base station 206, the externally-hung gun positioner 200 starts the satellite positioning module, the longitude and latitude of the gun are resolved from the Beidou satellite 205, and the related information is reported to the central server 202 through the communication base station 206, and the software client 203 located in the command control center and the APP end 204 located on duty can access the central server 202 through the communication network 207 and the communication base station 206 respectively to acquire the alarm and track information of the gun. The software client 203 can also complete the daily registration, allocation, reception, return and other service management operations of the guns according to the information of the RFID chip in the externally-hung gun positioner 200, can count and query the safety conditions of all the guns in the system in real time, and provides a whole set of complete solution for the safety management and control of the guns.

In summary, the externally-hung gun positioner 200 provided by the invention organically deploys the split functions in the device by a modular design mode, aiming at the characteristics of compact structure and high use requirement of the gun.
