Description

Technical Field

[0001] The invention relates to the technical field of police equipment, in particular to a Bluetooth anti-theft system for police high-speed tear gas equipment. Background Art

[0002] The electric-shock police high-speed tear gas device is a police device used to subdue criminals and then maintain social security. The electric-shock police high-speed tear gas device can use electricity to trigger tear gas, so that the tear gas is sprayed at the criminals at high speed, and then the criminals temporarily lose the ability to resist and struggle, and then the criminals are subdued. The electric-shock police high-speed tear gas device is a very practical police device; however, the electric-shock police high-speed tear gas device also has certain defects and shortcomings when in use. For example, the device is easily snatched or stolen by criminals when in use, and once the criminals steal or snatch the tear gas device, it will cause very serious problems, further increasing the harm to society. Secondly, the tear gas device at this stage lacks a positioning function, and the scope of use of the tear gas device cannot be limited according to the Beidou positioning function. After the criminals connect the holster and the gun body and steal it, they can use it in other places, which will cause great social harm. For this reason, the present invention proposes a police high-speed tear gas device equipped with a Bluetooth anti-theft system to solve this problem in a targeted manner. Summary of the invention

[0003] 1. Technical issues to be resolved In view of the deficiencies in the prior art, the present invention provides a Bluetooth anti-theft system for police high-speed tear gas equipment. By installing a first Bluetooth module in a holster and installing a second Bluetooth module on a circuit board in a tear gas gun body, the two Bluetooth modules are wirelessly connected to each other. When the tear gas gun body is away from the holster, the signal connection between the Bluetooths can be disconnected, and then the line switch is disconnected, so that the tear gas pressurized water pump in the tear gas gun body cannot work normally, thereby achieving the purpose of anti-theft. After the criminals steal the tear gas gun body, they cannot use it normally, thereby solving the problem that the tear gas gun is easily stolen at this stage, thereby increasing the harm.

[0004] (II) Technical solution In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions: A Bluetooth anti-theft system for police high-speed tear gas equipment comprises a tear gas gun body and a holster, and further comprises: a first Bluetooth module, which is installed on the holster; a second Bluetooth module, which is installed on a circuit board arranged in the tear gas gun body, and the first Bluetooth module and the second Bluetooth module are connected by short-range wireless signals; a line switch and a tear gas pressurized water pump, wherein the line switch and the tear gas pressurized water pump are both installed on the inner side of the tear gas gun body, the output end of the second Bluetooth module is electrically connected to the input end of the line switch, and the line switch is connected in series with the tear gas pressurized water pump, when the tear gas gun body is close to the holster, the line switch can be connected through the wireless connection relationship between the first Bluetooth module and the second Bluetooth module, and then the power supply circuit of the tear gas pressurized water pump is connected, so that the tear gas pressurized water pump can be used normally, and when the tear gas gun body and the holster are far away from each other, the tear gas pressurized water pump cannot work normally, thereby achieving the purpose of anti-theft of the tear gas gun body.

[0005] Furthermore, there is wireless short-distance transmission between the first Bluetooth module and the second Bluetooth module, and the distance is 10m. When the distance between the tear gas gun body and the holster exceeds 10m, the second Bluetooth module on the circuit board cannot receive the wireless signal, and then disconnects the line switch, causing the tear gas pressurized water pump to stop working.

[0006] Furthermore, a first power module is installed in the holster, and the first power module is connected in series with the first Bluetooth module.

[0007] Furthermore, a second power supply module is installed in the tear gas gun body to realize power supply processing of the second Bluetooth module and the tear gas pressurized water pump, and a power supply monitoring unit for monitoring the power of the second power supply module is installed on the inner side of the tear gas gun body, and the power supply monitoring unit includes: a voltage detection module, which is electrically connected to the positive circuit of the second power supply module; a controller, which is installed in the tear gas gun body, and the output end of the voltage detection module is electrically connected to the input end of the controller; an early warning module, including a buzzer and an indicator light installed on the outer shell of the tear gas gun body, and the output end of the controller is electrically connected to the input end of the buzzer and the input end of the indicator light respectively.

[0008] Furthermore, a tear gas control switch is installed at the wrench of the tear gas gun body, and the tear gas control switch is connected in series with the tear gas pressurized water pump.

[0009] Furthermore, a pepper water storage box is arranged in the tear gas gun body, the pepper water storage box is connected to the water inlet port of the tear gas pressurized water pump, and a liquid outlet is arranged on the tear gas gun body, and the pepper water discharged by the tear gas pressurized water pump can be sprayed out through the liquid outlet.

[0010] Furthermore, it also includes a Beidou positioning control unit installed in the tear gas gun body, and the Beidou positioning control unit includes: a Beidou positioning module, which is fixed in the tear gas gun body; a 4G Internet of Things card, which is installed in the tear gas gun body, and the Beidou positioning module is bidirectionally wirelessly connected to the first Bluetooth module on the holster through the 4G Internet of Things card; a storage module, which is installed in the tear gas gun body, and the output end of the Beidou positioning module is electrically connected to the input end of the storage module, and the storage module can store the trajectory information of the tear gas gun body according to the Beidou positioning module, and then realize the positioning and search of the tear gas gun body; a relay and a processor, which are both installed in the tear gas gun body, the output end of the Beidou positioning module is electrically connected to the input end of the processor, the relay is installed on the power supply circuit of the tear gas gun body, and the Beidou positioning module realizes real-time monitoring of the position information of the tear gas gun body. When the real-time position of the tear gas gun body exceeds the distance range set by the processor, the processor controls the relay, and then disconnects the second power supply module, so that the tear gas gun body cannot work.

[0011] Furthermore, it also includes a terminal device, which is a smart phone with map software downloaded on it. The Beidou positioning module is wirelessly connected to the terminal device through a 4G Internet of Things card, and then the location information of the tear gas gun body can be viewed in real time on the terminal device through the Beidou positioning module.

[0012] (III) Beneficial effects Compared with the prior art, the present invention provides a Bluetooth anti-theft system for police high-speed tear gas equipment, which has the following beneficial effects: 1. The present invention installs a first Bluetooth module in a holster and a second Bluetooth module on a circuit board in a tear gas gun body. The first Bluetooth module and the second Bluetooth module perform short-distance wireless signal transmission, and the distance is ten meters. When the tear gas gun body is close to the holster, the circuit switch can be connected through the relationship of the second Bluetooth module, thereby ensuring the working state of the tear gas pressurized water pump, so that the tear gas pressurized water pump can be used normally. When in use, the tear gas control switch is pressed, and then the tear gas pressurized water pump pumps out the water in the pepper water storage box to achieve the purpose of tear gas control. When lawbreakers steal or rob the tear gas gun body, the tear gas gun body is kept away from the holster, and then the signal relationship between the two Bluetooth modules is disconnected, thereby disconnecting the circuit switch, so that the tear gas pressurized water pump cannot work normally, and then the tear gas gun body cannot be used. Therefore, after the lawbreakers steal the tear gas gun body, they cannot use it, thereby avoiding harm to society, thereby achieving the purpose of anti-theft and safety protection, and realizing the normal use of the tear gas gun body.

[0013] 2. The present invention installs a Beidou positioning control unit on the tear gas gun body. The Beidou positioning control unit is mainly composed of a Beidou positioning module, a storage module, a processor and a relay. The Beidou positioning module can locate the position information of the tear gas gun body in real time, and can feed back the position information to the terminal device to realize real-time monitoring of its information. When criminals steal the tear gas gun body and the holster, they can only be used in a limited area. Therefore, police officers can quickly find the criminals and the tear gas gun according to the positioning information. When the criminals move the tear gas gun body and the holster outside the set area, the Beidou positioning module detects the real-time position of the tear gas gun body, and the processor controls the relay to work. The relay can disconnect the power supply circuit of the tear gas gun body, so that the tear gas gun body cannot work normally. Therefore, when the criminals move the tear gas gun body to the periphery of the set area, it cannot be used, thereby ensuring the safety of the equipment. The Beidou positioning module is wirelessly connected to the terminal device through a 4G Internet of Things card, and can monitor the position information of the tear gas gun body in real time.
