Description

Technical Field

[0001] The present invention relates to the technical field of law enforcement equipment, and in particular to a law enforcement recorder device. Background Art

[0002] Under the current new situation of fully promoting the optimization and upgrading of the standardization of law enforcement, equipping law enforcement personnel with and using law enforcement recorders is an important means and feasible method to adapt to the needs of the new situation, improve the level of law enforcement management, strengthen the standardization of the team, solve outstanding problems, and promote the rule of law in law enforcement work. The comprehensive promotion and use of portable law enforcement recorders has become a general trend.

[0003] Chinese patent CN107995449A discloses a police law enforcement recorder with anti-fall capability, comprising a shell, the inner wall of the shell is fixedly connected to a first fixed block, the first fixed block is fixedly connected to a first compression spring on a side away from the shell, the first compression spring is fixedly connected to a second fixed block on a side away from the first fixed block, and the second fixed block is fixedly connected to a recorder on a side away from the first compression spring. When the law enforcement recorder falls, the impact force generated by the police law enforcement recorder causes the second compression spring to deform, thereby reducing the impact force and improving the anti-fall capability of the law enforcement recorder. The compression force and rebound force of the first compression spring further improve the anti-fall capability of the law enforcement recorder, avoiding the problem of damage caused by the law enforcement recorder falling and the inability to retrieve on-site video data afterwards, which increases the difficulty of police officers in collecting evidence.

Example

[0050] Reference Figures 1 to 10 A law enforcement recorder device shown includes a shockproof housing 1 and a recording device 2. The shockproof housing 1 includes an outer housing 1a, a housing cover 1b and an inner housing 1c. The outer housing 1a and the housing cover 1b are combined into a closed housing. The inner housing 1c is fixedly installed inside the outer housing 1a and the housing cover 1b. The inner wall of the outer housing 1a is provided with a plurality of fixing columns 1a1 extending inwardly. The inner housing 1c is fixedly installed on the fixing columns 1a1. An elastic component 1a2 is provided between the inner housing 1c and the fixing columns 1a1. The inner housing 1c does not contact the inner walls of the outer housing 1a and the housing cover 1b. The recording device 2 is fixedly installed on the inner housing 1c.

[0051] A first slit-type air duct is formed between the outer wall of the inner shell 1c and the inner wall of the outer shell 1a, and a second slit-type air duct is formed between the outer wall of the inner shell 1c and the inner wall of the shell cover 1b. A first waterproof and breathable valve 3 and a second waterproof and breathable valve 4 are respectively installed on both sides of the top of the earthquake-resistant shell 1. A ventilation mechanism 5 is arranged inside the top of the earthquake-resistant shell 1. The ventilation mechanism 5 includes an isolation mechanism 5a and a blowing mechanism 5b. The isolation mechanism 5a divides the interior of the earthquake-resistant shell 1 into a first air duct and a second air duct. The first air duct connects the first waterproof and breathable valve 3 and the first slit-type air duct, and the second air duct connects the second waterproof and breathable valve 4 and the second slit-type air duct. The first air duct and the second air duct are connected through the gap between the bottom end of the inner shell 1c and the outer shell 1a, and the blowing mechanism 5b is fixedly installed inside the top of the earthquake-resistant shell 1.

[0052] The outer shell 1a and the shell cover 1b are fixed by glue to form a fully enclosed shell. The first waterproof breathable valve 3 and the second waterproof breathable valve 4 are used to exhaust air outward or inhale air inward respectively, so that the shockproof shell 1 has excellent waterproof and dustproof performance. The inner shell 1c is fixedly installed on the fixing column 1a1, and the elastic component 1a2 is a rubber ring, so that the recording device 2 is installed on the inner shell 1c to obtain excellent shockproof performance, so that the device is waterproof, dustproof and shockproof;

[0053] The outside air is sucked into the first air duct through the first waterproof breathable valve 3, then moves to the second air duct and is discharged through the second waterproof breathable valve 4. Specifically, the blowing mechanism 5b is used to blow air upward or downward at the bottom of the first waterproof breathable valve 3 and the second waterproof breathable valve 4, so that the outside air is sucked into the first waterproof breathable valve 3 and the internal air is discharged through the second waterproof breathable valve 4. The air sucked into the first waterproof breathable valve 3 passes through the first slit-type air duct between the outer shell 1a and the inner shell 1c, and takes away the heat from the back of the recording device 2. Then the air bypasses the gap between the bottom of the inner shell 1c and the outer shell 1a, and then passes through the second slit-type air duct between the shell cover 1b and the inner shell 1c, thereby taking away the heat from the front of the recording device 2. Finally, the hot air inside the seismic-resistant shell 1 moves upward to the second waterproof breathable valve 4 and is discharged, so that the device has excellent heat dissipation performance.

[0054] The recording device 2 includes a circuit board 2a, a video recording module 2b, a recording module 2c, and a power module 2d. The video recording module 2b, the recording module 2c, and the power module 2d are all electrically connected to the circuit board 2a. The shell cover 1b is provided with a light-transmitting window 1b1 located on the outside of the video recording module 2b. The recording module 2c extends downward from the bottom end of the recording device 2, passes through the inner shell 1c and the outer shell 1a in sequence, and then stays at the bottom end of the outer shell 1a. The recording module 2c and the outer shell 1a are sealed.

[0055] The power module 2d is used to supply power to the circuit board 2a. The video module 2b and the audio recording module 2c are powered by the circuit board 2a. The video module 2b records through the light-transmitting window 1b1. The audio recording module 2c records directly from the outside. The audio recording module 2c and the outer shell 1a are sealed by glue. The audio recording module 2c is a waterproof microphone, thereby ensuring the waterproof and dustproof performance of the shock-resistant shell 1.

[0056] The video recording module 2b includes an optical image stabilization camera 2b1 and a plurality of infrared night vision lights 2b2 arranged around the optical image stabilization camera 2b1.

[0057] The optical image stabilization camera 2b1 has optical image stabilization performance, thereby meeting the police's camera requirements during pursuit and fighting, and the infrared night vision light 2b2 can meet the police's camera requirements when enforcing the law at night.

[0058] A storage module, a communication module, a GPS module and a USB interface are integrated on the circuit board 2a, wherein the USB interface passes through the inner shell 1c and extends toward the bottom end of the outer shell 1a, and a USB socket 1a3 for USB access is provided at the bottom end of the outer shell 1a, and a waterproof rubber plug 1a4 is installed on the USB socket 1a3 to seal the USB socket 1a3.

[0059] The storage module, communication module, GPS module and USB interface enable the recording device 2 to have the functions of storing videos, wirelessly uploading videos, locating and downloading videos. When it is necessary to download videos, open the waterproof rubber plug 1a4, connect the USB port 1a3 to the computer via a data cable to download, and after the download is completed, plug the waterproof rubber plug 1a4 to ensure the waterproof and dustproof performance of the earthquake-resistant shell 1.

[0060] A mounting component 1a5 is provided on the rear surface of the outer casing 1a.

[0061] The mounting member 1a5 may be a clothespin, a pin, a bolt hole, etc., for fixing the device where needed.

[0062] A threaded hole is provided on the fixing column 1a1, and a plurality of mounting holes 1c1 corresponding to the fixing columns 1a1 are provided on the inner shell 1c. The inner shell 1c and the fixing columns 1a1 are connected by countersunk bolts, and the mounting holes 1c1 are countersunk holes.

[0063] The inner shell 1c is mounted on the fixing column 1a1 by means of countersunk bolts passing through the mounting holes 1c1, so that the inside of the inner shell 1c is a smooth surface, thereby facilitating the installation of the recording device 2 inside the inner shell 1c.

[0064] The isolation mechanism 5a includes a transverse partition 5a1 and multiple vertical partitions 5a2. The transverse partition 5a1 is parallel to the inner shell body 1c and is arranged around the inner shell body 1c. The transverse partition 5a1 abuts against the top and both sides of the inner wall of the outer shell body 1a. The vertical partition 5a2 extends vertically from the inner wall of the back plate of the outer shell body 1a toward the shell cover 1b and abuts against the inner wall of the shell cover 1b.

[0065] The transverse partition 5a1 is used to fill the gap between the inner shell 1c and the outer shell 1a, thereby separating the first slit-type air duct and the second slit-type air duct inside the outer shell 1a, restricting the airflow to pass through the bottom end of the inner shell 1c, and preventing the airflow from escaping through the gap between the top or both sides of the inner shell 1c and the outer shell 1a, resulting in poor heat dissipation.

[0066] The transverse partition 5a1 separates the power chamber 7, the air inlet chamber 6, the air outlet chamber 8 and the equipment chamber 9 inside the seismic-resistant shell 1. The air inlet chamber 6, the power chamber 7 and the air outlet chamber 89 are arranged in sequence from left to right inside the top end of the seismic-resistant shell 1. The equipment chamber is arranged below the air inlet chamber 6, the power chamber 7 and the air outlet chamber 8. The blowing mechanism 5b is installed in the power chamber, and the inner shell 1c is installed in the equipment chamber 9. The first waterproof air breathable valve 3 is connected to the air inlet chamber 6, and the second waterproof air breathable valve 4 is connected to the air outlet chamber 8. A second slit-type air duct partition plate 5a3 located between the transverse partition 5a1 and the shell cover 1b is arranged between the air inlet chamber 6 and the equipment chamber 8, and a first slit-type air duct partition plate 5a4 located between the transverse partition 5a1 and the outer shell 1a is arranged between the air outlet chamber 8 and the equipment chamber 9.

[0067] The second slit-type air duct partition plate 5a3 blocks the connection between the air inlet chamber 6 and the second slit-type air duct 11, and the first slit-type air duct partition plate 5a4 blocks the connection between the air outlet chamber 8 and the first slit-type air duct 10, so that the air sucked in by the first waterproof breathable valve 3 can only enter the first slit-type air duct 10 after passing through the air inlet chamber 6, and the air discharged from the second slit-type air duct 11 can only enter the second waterproof breathable valve 4 through the air outlet chamber 8.

[0068] The blowing mechanism 5b includes a dual-axis motor 5b1, a first axial flow fan 5b2 and a second axial flow fan 5b3. The dual-axis motor 5b1 is fixedly installed in the power chamber 7. The first axial flow fan 5b2 and the second axial flow fan 5b3 are respectively installed on the output shafts at both ends of the dual-axis motor 5b1. The first axial flow fan 5b2 is installed in the air inlet chamber 6, and the second axial flow fan 5b3 is installed in the air outlet chamber 8.

[0069] The dual-axis motor 5b1 drives the first axial flow fan 5b2 and the second axial flow fan 5b3 to rotate. The first axial flow fan 5b2 discharges the air in the first waterproof breathable valve 3 into the first slit air duct 10, and the second axial flow fan 5b3 draws the air in the second slit air duct 11 toward the second waterproof breathable valve 4.

[0070] The first axial flow fan 5b2 and the second axial flow fan 5b3 are both provided with a partition plate on the radial outer side, and the partition plate separates the air inlet chamber and the air outlet chamber into two cavities. The partition plate is provided with through holes which are sleeved on the first axial flow fan 5b2 and the second axial flow fan 5b3.

[0071] The partition plate can block the airflow outside the first axial fan 5b2 and the second axial fan 5b3, thereby firmly constraining the flow direction of the airflow in the first axial fan 5b2 and the second axial fan 5b3, thereby enhancing the blowing performance of the first axial fan 5b2 and the second axial fan 5b3.

[0072] Working principle:

[0073] The outer shell 1a and the shell cover 1b are fixed by glue to form a fully enclosed shell. The first waterproof breathable valve 3 and the second waterproof breathable valve 4 are used to exhaust air outward or inhale air inward respectively, so that the shockproof shell 1 has excellent waterproof and dustproof performance. The inner shell 1c is fixedly installed on the fixing column 1a1, and the elastic component 1a2 is a rubber ring, so that the recording device 2 is installed on the inner shell 1c to obtain excellent shockproof performance, so that the device is waterproof, dustproof and shockproof;

[0074] The dual-axis motor 5b1 drives the first axial flow fan 5b2 and the second axial flow fan 5b3 to work. The first axial flow fan 5b2 draws air from the outside, and the second axial flow fan 5b3 discharges the internal air to the outside, so that the outside air enters through the first waterproof breathable valve 3, and the cold air passes through the air inlet chamber and the first slit-type air duct from top to bottom, and then passes through the second slit-type channel and the air outlet chamber from bottom to top, and finally is discharged through the second waterproof breathable valve 4, so that the device has excellent heat dissipation performance;

[0075] When in use, the staff uses the optical image stabilization camera 2b1 to shoot video, uses the infrared night vision light 2b2 to assist in night shooting, and uses the recording module 2c to record. When it is necessary to download the video or charge, open the waterproof rubber plug 1a4 and connect the USB port 1a3 and the computer via a data cable. Example

[0076] The management system of law enforcement recorders includes law enforcement recorders, which are used to obtain sound information, image information and position information during law enforcement; the sound information, image information and position information are stored in a storage chip of the law enforcement recorder, and at the same time, the sound information, image information and position information are transmitted to a service terminal in real time via a wireless network; the service terminal processes the received sound information, image information and position information and displays them on a display screen in a command hall.

[0077] When working, law enforcement officers wear the law enforcement recorder on their chest with the camera facing forward to record image information, sound information and location information of the law enforcement process. The service terminal processes the data after receiving it and displays the processed image on the background display screen for the dispatchers in the command hall to review.

[0078] Since the data is recorded in both the law enforcement recorder and the server, law enforcement officers can not only retrieve and replay the law enforcement process on the spot for law enforcement officers to watch, but dispatchers in the command hall can also review it at the same time and provide auxiliary assistance. The two parties assist each other and jointly complete law enforcement. Example

[0079] This embodiment is a preferred solution of the second embodiment, that is, the service terminal performs face recognition comparison on the acquired image information, and transmits the comparison result to the law enforcement recorder in real time via a wireless network.

[0080] When the service terminal performs facial recognition comparison, only the criminals who are wanted online will be pushed to the law enforcement recorder. The information pushed is limited to the name and the corresponding wanted record, and the information involving privacy will not be pushed. At the same time, in order not to attract the attention of the law enforcement personnel, after the pushed message is received by the law enforcement recorder, the law enforcement recorder will remind the law enforcement personnel in a specific vibration way. At the same time, the pushed information is also displayed in real time on the display screen in the command hall, and the dispatch personnel will make the corresponding judgment. Example

[0081] This embodiment is another preferred solution of the second embodiment. The service terminal performs voiceprint recognition and comparison on the acquired sound information, and transmits the comparison result to the law enforcement recorder in real time via a wireless network.

[0082] When the service terminal performs voiceprint recognition and comparison, it is consistent with the face recognition of the image. Only criminals who are wanted online will be pushed to the law enforcement recorder. The information pushed is limited to the name and the corresponding wanted record. Information involving privacy will not be pushed. At the same time, in order not to attract the attention of the law enforcement officer, after the pushed message is received by the law enforcement recorder, the law enforcement recorder will remind the law enforcement officer in a specific vibration way. At the same time, the pushed information is also displayed in real time on the display screen in the command hall, and the dispatcher will make the corresponding judgment. Example

[0083] This embodiment is another preferred solution of the second embodiment. The service terminal records the voiceprint information of the law enforcer. When the service terminal detects a warning sound from the law enforcer, the service terminal sends a message to the command hall to prompt the law enforcer that he needs support.

[0084] In the fourth embodiment, all voiceprint information is compared with the voiceprint information in the database, while in the present embodiment, only the voiceprint information of the law enforcer is compared; that is, before use, the service terminal enters the voiceprint information of the law enforcer and matches the law enforcement recorder owned by the law enforcer; during the law enforcement process, when the law enforcer issues a warning to the person being enforced, such as "step back" or "don't move", the service terminal receives and recognizes it. If the law enforcer still encounters a situation in which support is needed during the law enforcement process, the service terminal sends a message to the command hall and automatically plays the image information, sound information and location information of the last minute, prompting the law enforcer that there is a situation in which support is needed, and the dispatcher in the command hall completes the dispatch. Example

[0085] This embodiment is another preferred solution of the second embodiment. The service terminal identifies the acquired image information. When the image changes dramatically, it is determined that the law enforcement officer may be moving at high speed and there is a possibility of pursuit. The service terminal then sends a message to the command hall to prompt the law enforcement officer that he needs support.

[0086] Generally speaking, law enforcement officers are in a stable state during the law enforcement process, and there may be short-term screen shaking. If the screen shaking lasts for more than 10 seconds, it means that the law enforcement officer is moving at high speed and there is a possibility of being pursued or being in personal danger. Therefore, the service terminal sends a message to the command hall and automatically plays the image information, sound information and location information of the last minute, prompting the law enforcement officer that he needs support. The dispatcher in the command hall will check the monitoring in time and complete the dispatch. Example

[0087] This embodiment is another preferred solution of the second embodiment. The service terminal identifies the acquired image information. When the image information has not changed, the location information of the law enforcement recorder is judged. If the location information has not changed, it is determined that the law enforcement officer may have encountered difficulties. The service terminal then sends a message to the command hall to prompt the law enforcement officer that he needs support.

[0088] This embodiment is exactly the opposite of the sixth embodiment. When the image information of the law enforcement officer has not changed, but the location information has changed, the law enforcement officer may be on the way; but when the location information has not changed, it means that the law enforcement recorder is fixed and the law enforcement officer may have encountered a dangerous situation. Therefore, the service terminal sends a message to the command hall and automatically plays the image information, sound information and location information of the last minute, prompting the law enforcement officer that he needs support. The dispatching personnel in the command hall will check the monitoring in time and complete the dispatch. Example

[0089] This embodiment is another preferred solution of the second embodiment. The service terminal only receives one or two of the image information, sound information, and location information, and determines that the law enforcement recorder has been damaged. Then the service terminal sends a message to the command hall to prompt the law enforcer that he needs support.

[0090] Under normal circumstances, the image information, sound information and location information should all be able to be obtained in a timely manner. If they cannot be fully obtained, it means that the law enforcement recorder has been damaged to a certain extent. Therefore, the service terminal sends information to the command hall and automatically plays the image information, sound information and location information of the last minute, prompting the law enforcement officer that there is a need for support. The dispatch personnel in the command hall will check the monitoring in time and complete the dispatch. Example

[0091] This embodiment is another preferred solution of the second embodiment. The law enforcement recorder is provided with a button for calling for help. When the service terminal receives the call for help information, it can directly find the location information of the nearby law enforcement recorders and send support information through the wireless network.

[0092] In an emergency, law enforcement officers can directly call for rescue with one click. There is no need to go through the command hall. The service terminal can send support information directly to nearby law enforcement recorder holders based on the acquired location information for support. Example

[0093] This embodiment is another preferred solution of the second embodiment, wherein the image information, sound information and location information are encrypted and then transmitted to the service terminal via a wireless network.

[0094] Encrypted information ensures fairness and prevents data from being tampered with.

[0095] It should be noted that the technical solutions of embodiments 2 to 10 can also be implemented on the same law enforcement recorder.

[0096] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
