Description

Technical Field

[0001] The present invention relates to the field of police processing technology, and in particular to a linkage video recording method, device, equipment and medium of a law enforcement instrument. Background Art

[0002] When the police are enforcing the law, usually one police car carries multiple police officers, the car is equipped with a body camera, and the police officers also wear portable body cameras. When the incident is urgent, there will be multiple police cars.

[0003] The vehicle-mounted body cameras and the portable body cameras carried by police officers are independent of each other. In the same law enforcement process or the same case, multiple body cameras need to be manually started by police officers to record separately, which makes it difficult to ensure that all devices start recording evidence. It is also difficult to quickly archive these videos according to the case and merge evidence from multiple devices. This situation may result in the failure to generate video evidence for some situations at the scene, affecting the efficiency of subsequent case evidence analysis. Summary of the invention

[0004] The present invention provides a linkage video recording method, device, equipment and medium for a body camera, so as to improve the efficiency of starting the video recording of the body camera and avoid affecting the efficiency of subsequent case evidence analysis due to missing the start of the video recording of the body camera.

[0005] According to one aspect of the present invention, a linkage recording method for a body camera is provided, comprising:

[0006] The linkage signal broadcast by the nearby linkage initiating body camera or linkage participating body camera;

[0007] If the linkage signal meets the linkage participation conditions, law enforcement video recording is performed according to the linkage signal;

[0008] The linkage signal is broadcast to nearby body cameras.

[0009] According to another aspect of the present invention, a linkage video recording device of a body camera is provided, comprising:

[0010] A signal receiving module, used for receiving linkage signals broadcast by nearby linkage initiating body cameras or linkage participating body cameras;

[0011] A signal response module, configured to record law enforcement video according to the linkage signal if the linkage signal meets the linkage participation condition;

[0012] The signal broadcast module is used to broadcast the linkage signal to nearby body cameras.

[0013] According to another aspect of the present invention, a computer program product is provided, including a computer program, wherein when the computer program is executed by a processor, the computer program implements the linkage recording method of the body camera according to any embodiment of the present invention.

[0014] According to another aspect of the present invention, an electronic device is provided, comprising: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores a computer program executable by the at least one processor, and the computer program is executed by the at least one processor so that the at least one processor can execute the linkage recording method of the body camera described in any embodiment of the present invention.

[0015] According to another aspect of the present invention, a computer-readable storage medium is provided, wherein the computer-readable storage medium stores computer instructions, and the computer instructions are used to enable a processor to implement the linkage recording method of the body camera described in any embodiment of the present invention when executed.

[0016] The embodiment of the present invention uses direct broadcasting and relay broadcasting of linkage signals to start the law enforcement recording of all body cameras near the law enforcement scene with one click, thereby ensuring the comprehensiveness of the evidence. There is no need to worry about missed reports by the body cameras at the scene, and at the same time it can remind police officers that a case has occurred nearby. In addition, since there is no need for the cloud to uniformly issue commands to start recording, false alarms by body cameras that are not at the scene are avoided.

[0024] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0025] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0026] Figure 1A This is a flow chart of a method for recording video in conjunction with a body camera provided by one embodiment of the present invention. This embodiment can be applied to the situation where a police officer manually turns on the recording function of any body camera and then other body cameras on the scene turn on their own recording functions in conjunction with each other. This method can be executed by a recording device in conjunction with a body camera. The device can be implemented in the form of hardware and / or software. The device can be configured in an electronic device with corresponding data processing capabilities, such as a body camera. Figure 1A As shown, the method includes:

[0027] S110, receiving a linkage signal broadcasted by a nearby linkage initiating body camera or a linkage participating body camera.

[0028] S120: If the linkage signal satisfies the linkage participation condition, law enforcement video recording is performed according to the linkage signal.

[0029] S130: Relay and broadcast the linkage signal to nearby body cameras.

[0030] Among them, the law enforcement devices can be divided into vehicle-mounted law enforcement devices fixed on vehicles and individual mobile law enforcement devices carried by police officers in terms of product form; in terms of linkage methods, they can be divided into linkage initiating law enforcement devices that respond to manual operations of police officers (such as pressing a recording button, entering a recording voice command) to initiate linkage recording, generate linkage signals, and directly broadcast linkage signals, as well as linkage participating law enforcement devices that respond to linkage signals to participate in linkage recording and relay broadcast linkage signals.

[0031] Specifically, Figure 1B As shown, the police officer manually turns on the law enforcement recording function of any body camera at the law enforcement scene. While recording the law enforcement, the body camera uses itself as a linkage initiator to generate a linkage signal and directly broadcasts the linkage signal to nearby body cameras.

[0032] After receiving the linkage signal, the nearby body camera analyzes the linkage signal to determine whether the linkage signal meets the linkage participation conditions.

[0033] If not satisfied, the current operating condition will continue to operate without responding to the linkage signal or relaying the linkage signal.

[0034] If it meets the requirements, it will participate in the body camera as a linkage and start its own law enforcement video recording function.

[0035] Since the linkage signal may be blocked, in order to ensure that there is no underreporting by the law enforcement devices near the linkage initiating body camera, after each body camera participating in the linkage receives the linkage signal, it is also necessary to act as an intermediate node to relay the linkage signal and then broadcast the linkage signal to the law enforcement devices near itself, thereby enhancing the linkage capability between the law enforcement devices in disguised form.

[0036] The nearby body cameras will also execute the above process when they receive the linkage signal of the relay broadcast. The specific process will not be repeated here. Therefore, for any body camera, the linkage signal it receives may come from the direct broadcast of the linkage initiating body camera, or from the relay broadcast of other linkage participating body cameras.

[0037] The embodiment of the present invention uses direct broadcasting and relay broadcasting of linkage signals to start the law enforcement recording of all body cameras near the law enforcement scene with one click, thereby ensuring the comprehensiveness of the evidence. There is no need to worry about missed reports by the body cameras at the scene, and at the same time it can remind police officers that a case has occurred nearby. In addition, since there is no need for the cloud to uniformly issue commands to start recording, false alarms by body cameras that are not at the scene are avoided.

[0038] Figure 2 This is a flowchart of a linkage recording method of a body camera provided by another embodiment of the present invention. This embodiment is optimized and improved on the basis of the above embodiment. Figure 2 As shown, the method includes:

[0039] S210, receiving a linkage signal broadcasted by a nearby linkage initiating body camera or a linkage participating body camera.

[0040] S220. If the linkage signal satisfies the linkage participation condition, determine the case type corresponding to the command word in the linkage signal and the video recording operation corresponding to the case type; and perform law enforcement video recording according to the video recording operation.

[0041] Specifically, each command word corresponds to a case type. And the recording operation for each case type is different. For example, the case types corresponding to command word 1 and command word 2 are emergency cases and non-emergency cases, respectively. The recording operation corresponding to the former is "recording with a high-definition model and issuing an emergency recording reminder", and the recording operation corresponding to the latter is "recording with a low-definition model and keeping silent". The law enforcement instrument determines the case type corresponding to the command word in the linkage signal based on the corresponding relationship pre-stored locally, and performs law enforcement recording according to the recording operation corresponding to the case type, so as to optimize the recording effect of the linkage recording.

[0042] S230: Add the traceability data of the current device to the linkage signal.

[0043] The traceability data includes the serial number of the current device and the timestamp of the current time.

[0044] Specifically, considering the need to merge and sort out the law enforcement videos from different body cameras in the future, the body cameras will add their own serial numbers and current time to the linkage signals before broadcasting them, so that the body cameras that receive the linkage signals in the future can know and record the source device and generation time of the linkage signals. When sorting out the case in the future, the linkage sequence of the linkage videos at the law enforcement scene can be quickly sorted out according to the traceability information recorded by each body camera, and the law enforcement videos from different body cameras can be quickly merged and sorted out.

[0045] Optionally, adding the traceability data of the current device to the linkage signal includes: replacing an existing serial number in the linkage signal with the serial number of the current device; and replacing an existing timestamp in the linkage signal with a timestamp of the current time.

[0046] Specifically, the length of the linkage signal is limited by the communication protocol, and sometimes too much traceability information cannot be added. To this end, the existing serial number in the linkage signal can be replaced with the serial number of the current device, and the existing timestamp in the linkage signal can be replaced with the timestamp of the current time. In this way, the traceability data of the current device can be added without affecting the length of the linkage signal, avoiding the linkage signal being too long due to the linkage chain being too long.

[0047] Exemplarily, the data structure of the core data in the linkage signal is shown in Table 1 below:

[0048] Table 1

[0049]

[0050] The core data in the linkage signal mainly consists of the protocol identifier, version, command word, serial number, sequence number, and timestamp. When the linkage signal is relayed and broadcast, the protocol identifier, version, command word, and serial number in the signal remain unchanged; the serial number and timestamp in the signal are replaced with the serial number of the current device and the timestamp of the current time.

[0051] S230: broadcast the linkage signal to nearby body cameras.

[0052] S240. The law enforcement video, the recording start time, the recording end time, the case type, the serial number of the current device and the existing serial number obtained by the law enforcement video are stored in association to obtain a law enforcement evidence file.

[0053] Specifically, in order to improve the efficiency of merging and sorting the law enforcement videos of different body cameras, after the on-site law enforcement is completed, the body camera will package and associate the law enforcement video, recording start time, recording end time, case type, serial number of the current device and the existing serial number in the response linkage signal obtained by the law enforcement video to obtain the law enforcement evidence file. The evidence file contains all the information required for the subsequent case analysis. The video evidence on multiple devices can be merged based on this information and uniformly merged and classified into the current case to facilitate case analysis.

[0054] Based on the above embodiment, optionally, the linkage signal is a Bluetooth signal, and the linkage signal is broadcast between the law enforcement devices via a Bluetooth networking protocol.

[0055] Specifically, the Bluetooth networking protocol may be the Bluetooth BLE4.0 standard broadcast packet protocol. Under this protocol, the linkage signal is divided into three data units, namely, device identification, device name, and custom data (ie, core data). The first byte of each data unit is the length, followed by the data content. The first byte of the data content is the AD Type, and the rest is the actual data. The maximum length of the linkage signal is limited to 31 bytes. Using the Bluetooth networking protocol to broadcast linkage signals can make full use of the existing Bluetooth-related hardware on the body camera. There is no need to upgrade the hardware of the body camera or re-purchase the body camera, which reduces the hardware cost required to achieve linkage recording.

[0056] On the basis of the above embodiment, optionally, the linkage participation condition includes that the serial number in the linkage signal is a serial number that has not been responded to.

[0057] Specifically, if the protocol identifier and version bits in the linkage signal are pre-agreed protocol identifiers and versions, the device name of the broadcast linkage signal matches the locally pre-stored device name, and the serial number in the linkage signal has not been responded to, then it is determined that the linkage signal meets the linkage participation conditions. If the protocol identifier and version bits in the linkage signal are not pre-agreed protocol identifiers and versions, the device name of the broadcast linkage signal does not match the locally pre-stored name, or the serial number has been responded to, then it is determined that the linkage signal does not meet the linkage participation conditions. By recording the serial numbers that have been responded to, the same serial number will not be responded to multiple times, preventing the body camera from repeatedly performing the linkage video recording evidence operation.

[0058] The embodiment of the present invention adds traceability data to the linkage signal. When sorting out the subsequent case, the linkage sequence of the linkage video recordings of the law enforcement scene can be quickly sorted out according to the traceability information recorded by each law enforcement instrument, and then the law enforcement videos of different law enforcement instruments can be quickly merged and sorted.
