Description

Technical Field

[0001] The present invention relates to the technical field of data acquisition, and particularly to a bullet and cartridge state acquisition terminal. Background Art

[0002] Currently, the management of firearms and ammunition mostly places them in special gun cabinets (boxes), and uses RFID radio frequency electronic tags and scanning and reading devices to feedback the information of firearms and ammunition to the background system for management; uses photoelectric sensors to sense when the firearm is taken off the rack to trigger an audible and visual alarm, and record the changes of firearms and ammunition. However, in this way, the special gun cabinet (box) requires a dedicated site, and the deployment is restricted by the fixed use site, and it cannot be flexibly and quickly deployed and recovered according to the actual application scenarios of users. It mainly conducts inventory check and registration management on static firearms and ammunition, and cannot effectively control firearms and ammunition in dynamic use scenarios. Moreover, it is necessary to place or attach the RFID chip into the firearms and ammunition, and the equipment deployment cannot be done without modifying the firearms and ammunition.

[0003] Furthermore, use specific customized ammunition belts or magazines (non-conventional supporting standard active equipment) integrated with RFID chips to record the changes of ammunition. It is necessary to use special magazine or ammunition belt equipment, with high costs, and cannot conduct real-time dynamic control on the ammunition in active magazines and ammunition belts. Restricted by RFID technology, for the changes of ammunition in dynamic and high-speed scenarios, the probability of false alarms and missed protections is high.

[0004] Therefore, the existing technology has defects and needs improvement. Summary of the Invention

[0005] The technical problem to be solved by the present invention is: to provide a bullet and cartridge state acquisition terminal, which can record the situation of ammunition in the magazine in real time, realize the accurate perception of the state of firearms and ammunition, the secure transmission of data, and the intelligent analysis of behaviors, so as to comprehensively improve the management efficiency and emergency response ability.

[0006] The technical solution of the present invention is as follows: Provide a bullet state acquisition terminal, including: a housing, a main board and a battery respectively installed in the housing, a main control chip, a pressure sensor, and a wireless transmission module respectively installed on the main board, a balance wing, a pressure probe respectively installed on the surface of the housing, and a buffer plate; the main control chip is respectively connected to the battery, the pressure sensor, and the wireless transmission module; the housing is provided with a probe hole, the pressure probe is installed at the probe hole, and both sides of the buffer plate are respectively abutted against the pressure sensor and the pressure probe; the housing can be loaded into the magazine like a bullet, the housing is provided with an acting plane, and the balance wing and the pressure probe are installed on the acting plane of the housing. The pressure probe is used to contact the spring of the magazine, conduct the pressure to the buffer plate, and then transmit it 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 supply power to each power-consuming module, the pressure sensor is used to obtain 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 shift when contacting the spring of the magazine, ensuring that the pressure probe contacts the spring of the magazine face to face. The buffer plate can better transmit the pressure borne by the pressure probe to the pressure sensor. The wireless transmission module can be selected from a WiFi module, a Bluetooth module, a LoRa module, a 2G communication module, a 3G communication module, a 4G communication module, a 5G communication module, etc. In this solution, the buffer plate does not mean providing buffering, but means being able to better receive the pressure of the pressure probe and transmit it to the pressure sensor.

[0007] During application, the bullet state acquisition terminal is pressed into the magazine as the first one, and then other ammunitions are pressed in. The bullet state acquisition terminal is then located at the bottommost position in the magazine. The pressure probe will be subjected to the pressure of the spring of the magazine and the gravity of the ammunition, acting on the pressure sensor. The pressure sensor can then collect pressure data in real time. Different numbers of ammunitions in the magazine result in different pressure data, thereby enabling the real-time acquisition of the change in the number of ammunitions in the magazine, that is, realizing the acquisition of the bullet state in the magazine.

[0008] Further, the housing includes: an upper housing and a lower housing connected to the upper housing. Adopting the structure of the upper housing and the lower housing facilitates assembly.

[0009] Further, one side surface of the outer shell is set as an L-shaped straight edge, and the tail end of the upper shell is set as a chamfered inclined surface. The chamfered inclined surface at the tail end of the upper shell and the single-sided L-shaped straight edge design will convert the horizontal thrust received at the tail of the bullet state acquisition terminal into a downward pressure at a 90-degree angle. Combining the outer shape structure of the single-sided L-shaped straight edge and the blocking effect of the mutual horizontal movement of the inner wall of the magazine, it can prevent the bullet state acquisition terminal from being pushed into the barrel (chamber) by the firearm firing mechanism (hammer) when there is no bullet in the magazine, which is a safety structure design for protecting the bullet state acquisition terminal.

[0010] Further, the other side surface of the outer shell is a gradient arc, and both the tail end and the front end of the outer shell are provided with transition rounded corners. The gradient arc enables the bullet state acquisition terminal to be easily pressed into the magazine like a bullet, and the transition rounded corners make the outer shape of the bullet state acquisition terminal round, which can reduce wear and scratching compared with sharp corners (such as right angles).

[0011] The overall outer shape of the outer shell adopts an irregular trapezoidal composite cavity structure design. Both the tail end and the front end of the outer shell are provided with transition rounded corners, a single-sided gradient arc design, a single-sided L-shaped straight edge design, and the tail end of the upper shell is set as a chamfered inclined surface. It maximally constructs and utilizes the effective available cavity space structure of a single bullet in the magazine, while not affecting operations such as bullet loading, bullet extraction, and ammunition firing.

[0012] Further, a sensor chamber is arranged inside the lower shell, the probe hole communicates with the sensor chamber, and the pressure sensor and the buffer plate are arranged in the sensor chamber. The sensor chamber can prevent the buffer plate from moving and also avoid interference from other electronic components inside the shell to the buffer plate and the pressure sensor, enabling the buffer plate to effectively conduct the pressure of the pressure probe to the pressure sensor.

[0013] Further, the bullet state acquisition terminal further includes: a plurality of fastening screws and a plurality of fastening nuts; the lower shell is provided with a plurality of nut holes, the fastening nuts are installed at the nut holes, the main board is provided with a plurality of mounting screw holes, and the fastening screws pass through the mounting screw holes and are connected to the fastening nuts. The fastening screws and the fastening nuts are used to fixedly install the main board inside the outer shell.

[0014] Further, the bullet state acquisition terminal further includes: a battery adapter, the adapter is electrically connected to the battery; the upper shell is provided with a battery compartment, the battery and the battery adapter are arranged in the battery compartment; the main board is installed with a conductive thimble, and the conductive thimble is electrically connected to the battery adapter. Using the battery adapter and the conductive thimble to supply power to the main board is convenient for battery layout. At the same time, without using a cable connection method, the battery adapter and the conductive thimble are directly plugged in, which is convenient for assembly.

[0015] Further, the bullet state acquisition terminal further includes: an external interface welded to the main board, and the external interface is 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 provided at the interface.

[0016] Further, the housing is divided into a front end portion and a rear end portion. The width of the front end portion is smaller than that of the rear end portion. One side of the rear end portion directly extends to one side of the front end portion, and the other side of the rear end portion contracts and then connects to the other side of the front end portion, thereby forming an L-shaped straight edge; the wireless transmission module is arranged in the front end portion. The different sizes of the front end portion and the rear end portion prevent the firing mechanism (hammer) of the firearm from pushing the bullet state acquisition terminal into the barrel (bore) when there is no bullet in the magazine, which is a safety structure design.

[0017] Further, there are two balance wings, and the two balance wings and the pressure probe are distributed in an isosceles triangle, and the pressure probe is arranged at the central position.

[0018] With the above solution, the present invention provides a bullet state acquisition terminal. When in use, the bullet state acquisition terminal is pressed into the magazine as the first one, and then other ammunitions are pressed in. The bullet state acquisition terminal is then located at the bottommost position in the magazine. The pressure probe will be subjected to the pressure of the spring in the magazine and the gravity of the ammunitions, acting on the pressure sensor. The pressure sensor can then collect the pressure data in real time. Different numbers of ammunitions in the magazine result in different pressure data, so that the change in the number of ammunitions in the magazine can be known in real time, that is, the acquisition of the bullet state in the magazine is realized.
