Description

Technical Field

[0001] This utility model relates to the field of data acquisition technology, and in particular to a bullet status acquisition terminal. Background Technology

[0002] Current methods for managing firearms and ammunition primarily involve storing them in dedicated firearm cabinets (boxes) and using RFID tags and scanning / reading devices to transmit firearm and ammunition information to a backend system for management. Photoelectric sensors detect when a firearm leaves the cabinet, triggering an audible and visual alarm and recording changes in the firearm and ammunition status. However, this approach requires dedicated firearm cabinets (boxes) and is limited by fixed locations, making it difficult to deploy and retrieve them flexibly and quickly according to the user's actual application scenarios. It mainly focuses on inventory and registration management of static firearms and ammunition, failing to effectively control firearms and ammunition in dynamic usage scenarios. Furthermore, the RFID chips need to be embedded or attached to the firearms and ammunition, meaning that equipment deployment cannot be done without altering the firearms and ammunition.

[0003] Furthermore, using custom-designed ammunition belts or magazines integrated with RFID chips (not standard equipment in service) to record ammunition changes. This requires dedicated magazine or belt equipment, is costly, and cannot provide real-time dynamic control over ammunition in existing magazines and belts. It is also limited by RFID technology, resulting in a high probability of false alarms and missed detections when dealing with ammunition changes in dynamic, high-speed scenarios.

[0004] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a gun and ammunition status acquisition terminal that records the status of ammunition in the magazine in real time, realizes accurate perception of the status of guns and ammunition, secure data transmission and intelligent analysis of behavior, thereby comprehensively improving control efficiency and emergency response capabilities.

[0006] The technical solution of this utility model is as follows: A bullet status acquisition terminal is provided, comprising: a housing, a main board and a battery respectively installed inside the housing, a main control chip, a pressure sensor, and a wireless transmission module respectively installed on the main board, a balance wing and a pressure probe respectively installed on the surface of the housing, and a buffer plate; the main control chip is connected to the battery, pressure sensor, and wireless transmission module respectively; the housing is provided with a probe hole, the pressure probe is installed at the probe hole, and the two sides of the buffer plate abut against the pressure sensor and the pressure probe respectively; the housing can be inserted into a magazine like a bullet, the housing is provided with an action plane, and the balance wing and pressure probe are installed on the action plane of the housing. The pressure probe is used to contact the spring of the magazine, transmit the pressure to the buffer plate, and then to the pressure sensor. The pressure sensor collects pressure data in real time and transmits it to the main control chip. The main control chip transmits the pressure data to the management platform through the wireless transmission module. The battery is used to power each power module, the pressure sensor is used to acquire pressure data in real time, the wireless transmission module is used to transmit data, and the balance wing is used to ensure that the pressure probe does not deviate when contacting the spring of the magazine, ensuring that the pressure probe contacts the spring of the magazine head-on. The buffer plate can better transmit the pressure from the pressure probe to the pressure sensor. The wireless transmission module can be a WiFi module, Bluetooth module, LoRa module, 2G communication module, 3G communication module, 4G communication module, 5G communication module, etc. In this solution, the buffer plate does not refer to providing buffering, but rather to its ability to better withstand the pressure from the pressure probe and transmit it to the pressure sensor.

[0007] In application, the ammunition status acquisition terminal is inserted first into the magazine, followed by the insertion of other ammunition. The ammunition status acquisition terminal is then positioned at the bottom of the magazine. The pressure probe is then subjected to the pressure of the magazine spring and the weight of the ammunition, which acts on the pressure sensor. The pressure sensor can then collect pressure data in real time. Different numbers of ammunition in the magazine result in different pressure data, thus enabling real-time monitoring of changes in the number of ammunition in the magazine, thereby achieving the acquisition of the ammunition status within the magazine.

[0008] Furthermore, the outer shell includes: an upper shell and a lower shell connected to the upper shell. The upper and lower shell structure facilitates assembly.

[0009] Furthermore, one side of the outer shell is designed as an L-shaped straight edge, and the rear end of the upper shell is designed as a chamfered bevel. The chamfered bevel and the single-sided L-shaped straight edge design at the rear end of the upper shell convert the horizontal thrust received by the ammunition status acquisition terminal into a 90-degree downward pressure. Combined with the obstruction effect of the single-sided L-shaped straight edge and the mutual horizontal movement of the inner wall of the magazine, this safety structure design prevents the firing mechanism (hammer) from pushing the ammunition status acquisition terminal into the barrel (chamber) when there is no ammunition in the magazine, thus protecting the ammunition status acquisition terminal.

[0010] Furthermore, the other side of the outer casing has a gradient curvature, and both the rear and front ends of the outer casing are provided with transition rounded corners. The gradient curvature allows the bullet status acquisition terminal to be easily pressed into the magazine like a bullet, and the transition rounded corners make the bullet status acquisition terminal have a rounded shape, which can reduce wear and scratches compared to sharp corners (such as right angles).

[0011] The overall shape of the outer shell adopts an irregular trapezoidal composite cavity structure design. The rear and front ends of the outer shell are equipped with transition rounded corners, a single-sided gradient arc design, a single-sided L-shaped straight edge design, and the rear end of the upper shell is set as a chamfered bevel. This maximizes the effective usable cavity space structure of a single bullet within the magazine, without affecting operations such as loading, unloading, and firing.

[0012] Furthermore, a sensor compartment is provided inside the lower shell, and the probe hole communicates with the sensor compartment. The pressure sensor and the buffer plate are disposed inside the sensor compartment. The sensor compartment can prevent the buffer plate from moving and can also prevent other electronic components inside the shell from interfering with the buffer plate and the pressure sensor, so that the buffer plate can effectively transmit the pressure from the pressure probe to the pressure sensor.

[0013] Furthermore, the bullet status acquisition terminal also includes: a plurality of fastening screws and a plurality of fastening nuts; the lower housing is provided with a plurality of nut holes, the fastening nuts are installed in the nut holes, and the main board is provided with a plurality of mounting screw holes, the fastening screws passing through the mounting screw holes and connecting to the fastening nuts. The fastening screws and fastening nuts are used to fix the main board in the housing.

[0014] Furthermore, the ammunition status acquisition terminal also includes: a battery adapter, which is electrically connected to the battery; a battery compartment is provided on the upper shell, and the battery and battery adapter are disposed within the battery compartment; a conductive pin is mounted on the main board, and the conductive pin is electrically connected to the battery adapter. Powering the main board using the battery adapter and the conductive pin facilitates battery layout. Simultaneously, by eliminating the use of cables, the battery adapter and the conductive pin are directly plugged in, simplifying assembly.

[0015] Furthermore, the bullet status acquisition terminal also includes: an external interface soldered on the motherboard, the external interface being a battery charging interface and / or an information transmission interface; an interface hole is provided at the tail end of the housing, and the external interface is located at the interface.

[0016] Furthermore, the outer casing is divided into a front end and a rear end. The width of the front end is smaller than the width of the rear end. One side of the rear end extends directly to one side of the front end, and the other side of the rear end contracts and connects to the other side of the front end, thus forming an L-shaped straight edge. The wireless transmission module is located at the front end. The front and rear ends are of different sizes to prevent the firing mechanism (hammer) from pushing the ammunition status acquisition terminal into the barrel (chamber) when there is no ammunition in the magazine.

[0017] Furthermore, there are two balance wings, and the two balance wings and pressure probes are distributed in an isosceles triangle, with the pressure probes positioned in the center.

[0018] Using the above solution, this utility model provides a bullet status acquisition terminal. In application, the bullet status acquisition terminal is inserted first into the magazine, followed by the insertion of other ammunition. The bullet status acquisition terminal is then positioned at the bottom of the magazine. The pressure probe is then subjected to the pressure of the magazine spring and the weight of the ammunition, which acts on the pressure sensor. The pressure sensor can then collect pressure data in real time. Different quantities of ammunition in the magazine result in different pressure data, thus enabling real-time monitoring of changes in the quantity of ammunition in the magazine, thereby achieving the acquisition of the bullet status within the magazine.
