[0014] Compared with existing technologies, the advantages of a law enforcement recorder that supports voice recognition are: 1. Through the provided wearing mechanism and connecting mechanism, when law enforcement officers need to wear law enforcement recorders during on-site law enforcement, they first hang the two hooks on the waist of the law enforcement officers, then carry the elastic belt on the shoulders of the law enforcement officers and tighten the elastic belt, then adjust the wearing position of the law enforcement recorder through the wearing mechanism, and then adjust the shooting angle of the law enforcement recorder body through the connecting mechanism. These adjustments of the law enforcement recorder body can, on the one hand, match the shooting position of the law enforcement recorder body 1 with the height of the law enforcement officers, and on the other hand, ensure the optimal shooting field of view of the law enforcement recorder, try to ensure the clarity of the law enforcement video shot by the law enforcement recorder, and improve the reliability and effect of the use of the law enforcement recorder.

[0015] 2. Through the radio structure, AI chip and lithium battery, when the law enforcement officer needs to read out the laws and regulations on which the law enforcement is based to the person being enforced, first move the microphone to the corner of the law enforcement officer's mouth, then the law enforcement officer asks the microphone what laws and regulations the law enforcement is based on, and then the radio structure converts the voice question into an electrical signal and transmits it to the AI ​​chip, and through the large model that processes the data inside the AI ​​chip, the AI ​​chip can call out accurate laws and regulations from the data storage bar, and automatically and clearly broadcast these laws and regulations through the speaker of the law enforcement recorder, avoiding the reading of laws and regulations. The unclear voice recognition leads to irregular law enforcement, and because the AI ​​chip has a large amount of computing power, the power consumption of the law enforcement recorder is also greater. Therefore, by adding a lithium battery in the L-shaped shell, the use time of the law enforcement recorder can be effectively increased. This mechanism enables the law enforcement recorder to have the function of automatic and clear broadcast of voice recognition and the provisions of laws and regulations on which law enforcement is based. It can not only effectively ensure the legality of law enforcement personnel's law enforcement, but also ensure the effect of on-site law enforcement. In addition, by adding a lithium battery, the AI ​​chip can avoid excessive power consumption and affect the battery life of the law enforcement recorder, thereby effectively improving the reliability of the use of the law enforcement recorder.

[0016] 3. Through the temperature adjustment mechanism set up, due to the large amount of heat dissipation caused by the AI ​​chip's large-scale calculations, and when a high-temperature environment is formed inside the body of the law enforcement recorder, the temperature control mechanism uses a micro air pump and the first semiconductor refrigeration film to transport low-temperature air to the body of the law enforcement recorder to achieve rapid cooling and avoid the law enforcement recorder operating system and voice recognition program from running stuck due to high temperature. If the law enforcement recorder body is used in a low-temperature environment, the temperature adjustment mechanism uses a micro air pump and the second semiconductor refrigeration film to transport air with a raised temperature to the body of the law enforcement recorder, which can increase the temperature inside the body of the law enforcement recorder and avoid the electronic components from being disturbed by the low-temperature environment. This mechanism enables the law enforcement recorder to automatically adjust the temperature according to the ambient temperature, which can not only improve the stability of the use of the law enforcement recorder, but also improve the battery life of the law enforcement recorder, as well as improve the reliability and effectiveness of the use of the law enforcement recorder.

This mechanism enables the law enforcement recorder to automatically adjust the temperature according to the ambient temperature, which can not only improve the stability of the law enforcement recorder, but also improve the battery life of the law enforcement recorder, as well as improve the reliability and effect of the law enforcement recorder.

[0024] The outer wall of the L-shaped shell 12 is fixedly connected to a wearing mechanism 9, and the wearing mechanism 9 includes a rectangular frame 91 fixedly connected to the outer wall of the L-shaped shell 12, and the inner wall of the rectangular frame 91 is movably connected to an elastic band 92, and the width of the elastic band 92 is 1.8-2.5 cm, and both ends of the elastic band 92 are fixedly connected to hooks 93, and a square hole is provided on the top outer wall of the rectangular frame 91, and the hole wall of the square hole is movably connected to a T-shaped rod 94, and the side end of the T-shaped rod 94 is fixedly connected to a rack 95, and the rod wall of the T-shaped rod 94 is movably sleeved with a second spring 96, and the two ends of the second spring 96 are respectively fixedly connected to the outer wall of the T-shaped rod 94 and the surface of the rack 95. This mechanism can improve the convenience and efficiency of wearing the law enforcement recorder.

[0025] The temperature sensor 54 is electrically connected to the input end of the micro PLC controller 82 through a wire, and the micro air pump 81, the first semiconductor refrigeration plate 84 and the second semiconductor refrigeration plate 85 are electrically connected to the output end of the micro PLC controller 82 through a wire. The above-mentioned power-on devices and electrical connections are all prior arts and are well known to those skilled in the art, and will not be repeated here.

[0026] The operating principle of the present invention is now described as follows: when law enforcement officers need to wear a law enforcement recorder during on-site law enforcement, they first mount the two hooks 93 on the waist of the law enforcement officers, then carry the elastic belt 92 on the shoulders of the law enforcement officers, and tighten the elastic belt 92, and at the same time, push the T-shaped rod 94 outward, the outward movement of the T-shaped rod 94 stretches the second spring 96 and generates a restoring force, then the rectangular frame 91 moves on the elastic belt 92, and the position of the law enforcement recorder body 1 is adjusted. After the position of the law enforcement recorder is adjusted, the T-shaped rod 94 is released, and the T-shaped rod 94 pushes the rack 95 to squeeze the elastic belt 92 under the action of the restoring force of the second spring 96, and the teeth of the rack 95 can penetrate the surface of the elastic belt 92, increasing the friction between the rack 95 and the elastic belt 92, and at the same time, it can ensure that the position of the law enforcement recorder body 1 is stably maintained after adjustment, thereby improving the stability of wearing the law enforcement recorder; In addition, the shooting angle of the law enforcement recorder body 1 can be adjusted through the connecting mechanism 6. Specifically, after the law enforcement recorder body 1 is deflected, the law enforcement recorder body 1 drives the connecting shell 62 to deflect through the plug rod 11, and the connecting shell 62 is deflected through the connecting rod 63. After the connecting rod 63 is deflected, the friction between the rubber damping sleeve 65 and the side plate 64 can ensure the stability of the law enforcement recorder body 1 after the shooting angle is adjusted. Moreover, the law enforcement recorder body 1 is assembled with the connecting mechanism 6 by plugging through the plug rod 11 and the air guide mechanism 7. This assembly method can conveniently remove the law enforcement recorder body 1 and can conveniently view the captured law enforcement video data from the back screen of the law enforcement recorder body 1. These adjustments of the law enforcement recorder body 1, on the one hand, make the shooting position of the law enforcement recorder body 1 match the height of the law enforcement personnel, and on the other hand, can ensure the optimal shooting field of view of the law enforcement recorder and try to ensure the clarity of the law enforcement video captured by the law enforcement recorder. This mechanism enables the law enforcement recorder to have the functions of stable wearing and convenient adjustment of the wearing position, thereby improving the reliability and effect of the use of the law enforcement recorder. When the law enforcement officer needs to read out the legal provisions for the enforcement to the person being enforced, the law enforcement officer moves the microphone 53 to the corner of the law enforcement officer's mouth through the positioning wire 52, and then the law enforcement officer asks the microphone 53 what legal provisions the enforcement is based on. After that, the microphone 53 converts the collected question voice into a voice electrical signal, and transmits the voice electrical signal to the main board of the law enforcement recorder body 1. The main board of the law enforcement recorder body 1 then transmits the voice electrical signal to the AI ​​chip 4. After the voice electrical signal is processed by the large model for processing data inside the AI ​​chip 4, the AI ​​chip 4 can retrieve accurate legal provisions information from the data storage bar 10, and transmit this legal provisions information to the main board speaker of the law enforcement recorder body 1. Finally, the speaker of the law enforcement recorder body 1 can automatically and clearly broadcast the legal provisions on which the law enforcement officers are based, avoiding irregular law enforcement due to unclear reading of the legal provisions. In addition, due to the large amount of computing power of the AI ​​chip 4, the power consumption of the law enforcement recorder is also increased. The L-shaped housing 12 is large, so by adding a lithium battery 14 in the L-shaped housing 12, the use time of the law enforcement recorder body 1 can be effectively increased. In addition, the design of the microphone 53 does not require the law enforcement personnel to lean their heads close to the law enforcement recorder body 1 to ask voice questions, which saves time and effort and improves the convenience of the law enforcement recorder body 1 to ask voice questions. In addition, the wearing mechanism 9 can effectively deal with the discomfort caused by the increase in the weight of the law enforcement recorder due to the addition of the lithium battery 14 and the temperature adjustment mechanism 8. Specifically, the pressure on the law enforcement personnel when wearing the law enforcement recorder is shared by the wider elastic band 92, and the uniformity of the pressure distribution is improved, thereby improving the comfort of wearing the law enforcement recorder. The mechanism enables the law enforcement recorder to have the functions of voice recognition and automatic and clear broadcasting of law enforcement according to the provisions of laws and regulations, which can not only effectively ensure the legality of the law enforcement personnel's law enforcement, but also ensure the effect of on-site law enforcement. In addition, by adding a lithium battery 14, it is possible to avoid the situation where the AI ​​chip 4 consumes too much power and affects the battery life of the law enforcement recorder, thereby effectively improving the reliability of the use of the law enforcement recorder. When the AI ​​chip 4 dissipates heat seriously due to a large amount of calculations, thereby forming a high-temperature environment inside the law enforcement recorder body 1, the temperature sensor 54 monitors the temperature inside the law enforcement recorder body 1 through the rubber tube 51 connected to the law enforcement recorder body 1, and the temperature sensor 54 will convert the detected temperature value into an electrical signal and transmit it to the micro PLC controller 82. If the temperature value detected by the temperature sensor 54 exceeds the high temperature threshold of 30°C preset by the micro PLC controller 82, the micro PLC controller 82 controls the first semiconductor refrigeration plate 84 and the micro air pump 81 to be powered on and started. The first semiconductor refrigeration plate 84 can reduce the temperature of the metal mesh 17, and the metal mesh 17 can increase the cooling area of ​​the first semiconductor refrigeration plate 84. At the same time, the heat dissipation speed of the first semiconductor refrigeration plate 84 can be accelerated through the heat conductive plate 18, thereby improving the cooling effect of the first semiconductor refrigeration plate 84, and then the temperature inside the L-shaped shell 12 can be reduced. After the micro air pump 81 draws air, the L-shaped shell 12 passes The dustproof mesh 86 sucks in external air to replenish it, so as to ensure the air pressure balance inside the L-shaped shell 12. After the external air enters the L-shaped shell 12, it is cooled by the low-temperature first semiconductor refrigeration sheet 84 and the metal mesh 17. The cooled air enters the interior of the law enforcement recorder body 1 through the hose 83, the air guide tube 76, the air vent 77 and the connecting cover 71. The AI ​​chip 4, the data storage strip 10 and the electronic components inside the law enforcement recorder body 1 are quickly cooled by the low-temperature and flowing air. The cooled air is discharged through the rubber tube 51 and the exhaust arc tube 55 to avoid the law enforcement recorder operating system and voice recognition program from running stuck due to high temperature. In addition, after the air temperature discharged from the law enforcement recorder body 1 reaches the 20°C safety temperature threshold preset by the micro PLC controller 82, the temperature sensor 54 sends an electrical signal to the micro PLC controller 82, and then the micro PLC controller 82 controls the micro air pump 81 and the first semiconductor refrigeration sheet 84 to stop working, thereby reducing the power consumption of the law enforcement recorder; If the law enforcement recorder body 1 is used in a low temperature environment, at this time, after the temperature sensor 54 detects that the internal temperature of the law enforcement recorder body 1 is lower than the 5°C low temperature threshold preset by the micro PLC controller 82, the micro PLC controller 82 controls the micro air pump 81 and the second semiconductor refrigeration sheet 85 to start. Since the heat dissipation side of the second semiconductor refrigeration sheet 85 is in contact with the metal mesh 17, the second semiconductor refrigeration sheet 85 and the metal mesh 17 can increase the temperature inside the L-shaped shell 12. When the micro air pump 81 draws external air into the L-shaped shell 12, the temperature can be increased by the heat dissipation side of the second semiconductor refrigeration sheet 85. In addition, the temperature increase inside the L-shaped shell 12 can also protect the lithium battery 14, so that the lithium battery 14 can be protected. The electrochemical reaction inside the battery 14 is at a suitable temperature, thereby promoting the efficiency of the electrochemical reaction and ensuring that the lithium battery 14 can supply more electricity, thereby increasing the battery life of the law enforcement recorder in a low-temperature environment. The air with increased temperature is then transported to the law enforcement recorder body 1 through the hose 83, the air duct 76, the air vents 77 and the connecting cover 71, which can increase the temperature inside the law enforcement recorder body 1 and prevent the electronic components from being disturbed by the low-temperature environment. This mechanism enables the law enforcement recorder to automatically adjust the temperature according to the ambient temperature, which can not only improve the stability of the law enforcement recorder, but also increase the battery life of the law enforcement recorder, as well as improve the reliability and effectiveness of the law enforcement recorder.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
