Embodiments of the invention

[0031] In the following description, for purposes of illustration and description However, it will be apparent to those skilled in the art that the present invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details. The description of the invention is impeded.

[0032] In order to explain the technical solution described in the present invention, the following description will be made by way of specific embodiments.

Embodiment 1

[0034] Please refer to FIG. 1 , which illustrates a data recording method according to an embodiment of the present invention, which is applied to a system including a single police law enforcement audio and video recorder, a vehicle hard disk recorder, and a monitoring server, and the single police law enforcement audio and video recording. The instrument and the onboard hard disk recorder are wirelessly connected, and the onboard hard disk recorder and the monitoring server are wirelessly connected.

[0035] The single police law enforcement audio and video recorder is an audio and video recording device that is easy to carry around, and is widely used in law enforcement departments, such as police and other city management personnel. Car DVRs are mainly used for vehicle safety monitoring. For law enforcement agencies, they are generally used for full-scale audio and video monitoring of law enforcement sites. Since the single-war enforcement video recorder and the in-vehicle DVR have different hardware codec schemes, they have been used separately as two different products. There is no system to integrate the two. However, after data playback, law enforcement personnel need to search for relevant data from different devices, which is very inconvenient.

[0036] In view of this, the embodiments of the present invention provide a data recording method, system, video and audio recorder, and in-vehicle hard disk recorder, which are designed to solve the data recorded by the single police law enforcement audio and video recorder and the onboard hard disk recorder. Data playback is a problem with inconvenient operation.

[0037] The data recording method of the embodiment of the present invention includes:

[0038] 101. The single police law enforcement audio and video recorder collects first data, and sends the first data to the onboard hard disk recorder;

[0039] The single police law enforcement audio and video recorder may be one or more, and the first data may be various types of data such as audio, video, text and images. The single police enforcement video recorder and the car DVR are connected via a wireless network, such as WIFI or Bluetooth. When a single police law enforcement audio and video recorder is connected to the car DVR, it can be regarded as a car DVR. One of the common video channels is the seamless integration of the two. When the single police enforcement video recorder is connected to the car DVR, the single police law enforcement audio and video recorder will transfer the data collected by itself to the car DVR for storage, so that the car DVR can pass after data playback. The data collected by its own video channel and the data received by the single police law enforcement video recorder Playback is performed to achieve synchronized playback of associated data.

[0040] Based on the single police enforcement video recorder, it is necessary to transmit large data such as video to the in-vehicle DVR, and it is preferable to use WIFI for connection between them. However, WIFI connections also have certain limitations, such as being susceptible to various signal interferences. When the single police enforcement video recorder and the car DVR are disconnected, the single police law enforcement audio and video recorder will collect data independently. After reconnecting, the single police law enforcement audio and video recorder will send the unsent data to the car hard disk. The recorder is saved.

[0041] Further, in order to improve the stability of the communication, the single police law enforcement audio and video recorder and the in-vehicle hard disk recorder are connected by a WIFI connection of a 2.4G/5G dual-band design, and the data recording method may further include:

[0042] the single police law enforcement audio and video recorder obtains environmental information and signal interference intensity of the site, and the environmental information includes a volume of an obstacle that hinders transmission of the WIFI signal;

[0043] when the volume of the obstacle blocking the transmission of the WIFI signal is greater than the first threshold or the signal interference strength is less than the second threshold, the single police law enforcement audio and video recorder passes the WIFI signal of the 2.4G frequency band and the Car DVR connection;

[0044] when the volume of the obstacle blocking the transmission of the WIFI signal is less than the first threshold or the signal interference intensity is greater than the second threshold, the single police law enforcement audio and video recorder passes the WIFI signal of the 5G frequency band and the vehicle DVR connection.

[0045] For the 2.4G band WIFI signal, its ability to penetrate obstacles is strong, but since a large number of devices use signals in this frequency band, the signal interference is more. For the WIFI signal in the 5G band, its ability to penetrate obstacles is poor, but the signal interference is less. Therefore, switching the WIFI signal frequency band between the single police enforcement video recorder and the vehicle hard disk recorder according to the environmental information and the signal interference intensity of the site can effectively improve the stability of the communication connection.

[0046] Further, the data recording method may further include:

[0047] The single police law enforcement audio and video recorder obtains attendance registration information, and transmits the attendance registration information to the onboard hard disk recorder.

[0048] In the prior art in-vehicle DVR, it is generally required to design a UI, or use an RFC card and the like to perform the attendance equipment and software functions, and the relevant personnel need to register on the in-vehicle DVR first after attending the work. However, in this way, there is a possibility that the relevant person forgets to register on the in-vehicle DVR. In the embodiment of the present invention, the relevant personnel even forget to enter the on-board hard disk recorder. Registration of the line, you can still enter the attendance registration information through the single-arm enforcement video and audio recorder that you carry with you. The single-inspection video and audio recorder automatically performs the attendance registration on the on-board DVR, which can avoid the incomplete evidence caused by the missed attendance registration. phenomenon.

[0049] 102. The in-vehicle DVR collects second data, and sends the second data and the received first data to the monitoring server.

[0050] The second data is any data collected by the on-board DVR through its own video channel, and is generally audio and video data of the data collection site. The monitoring server is a remote terminal server, such as a system platform with related application software in the law enforcement center. The car DVR and the monitoring server are connected via a wireless network, such as WIFI, 3G or 4G. The onboard DVR can upload its stored data to the monitoring server, including the second data collected by itself and the first data obtained from the single police law enforcement audio and video recorder.

[0051] 103. The monitoring server receives and records the first data and the second data.

[0052] The monitoring server is capable of receiving and recording the first data and the second data uploaded by the onboard hard disk recorder, and can also perform real-time monitoring on the onboard hard disk recorder and the single police law enforcement audio and video recorder to realize remote command , the overall control of the scene. The first data and the second data are associated by the identification information included in the data field. Specifically, the identification information may be common information of data collected by the onboard hard disk recorder and the single police law enforcement audio and video recorder, and may include, for example, a law enforcement personnel number, a device number, a license plate number, and a daytime information. After the data collected by different devices are associated by the identification information, the monitoring server can accurately distinguish different data corresponding to each event to form a complete data chain of each event.

[0053] Specifically, the first data and the second data may be associated by using the following steps:

After receiving the first data, the onboard hard disk recorder acquires the identification information of the first data, and the identification information of the second data that has been collected and the identification information of the first data. The second data that meets certain conditions is associated with the first data.

[0055] If the identification information of the first data and the identification information of the second data meet certain conditions, it indicates that the first data and the second data are related to each other. The certain condition may be that the identification information is completely the same, or the identification information includes a part of the same content, for example, the different data with the same law enforcement personnel number and the license plate number may be associated, or the same different data of the collection time may be associated. . [0056] Further, the data recording method may further include:

[0057] After acquiring the data playback instruction, the monitoring server displays the associated first data and second data in the same display interface.

[0058] In the data playback phase, a related person can input a data playback instruction on the monitoring server to view all data associated with the specified event in the same display interface. In an actual application, the display interface of the terminal may be divided into multiple display areas, and each display area displays specified data collected by the specified device, and the content displayed by each display area in the same interval may be related data. For example, the data related to a specified event, collected by the single police law enforcement audio recorder or the onboard hard disk recorder, and all the audio, video, positioning information, event markers and text descriptions located in the specified segment are in the same Displayed in the display interface, so that relevant personnel can investigate the specified event.

[0059] Further, the data recording method may further include:

[0060] The single police law enforcement audio and video recorder sends the first data directly to the monitoring server.

[0061] The prior art single police law enforcement audio and video recorder uploads data to the server, generally accesses the collection station through the USB interface, and then the data is uploaded to the server by the collection station through the network port connection. Although u

The SB interface is more versatile, but the problem of unrecognized devices may occur through USB access, and the cost of setting up the collection station is also high. When the single police law enforcement audio and video recorder successfully establishes a connection relationship with the server, the single police law enforcement audio and video recorder is equivalent to a common storage medium of the server, so the server also needs to install the corresponding data playback software for the single police enforcement video and audio recording. The data collected by the instrument is played back.

[0062] In the embodiment of the present invention, the single police law enforcement audio and video recorder can directly communicate with the server, for example, can directly connect to the server through WIFI, and the server can access the single police law enforcement audio and video recorder through the IP address. Then, the data of the single police enforcement video recorder can be played back through a browser, etc., without installing the data playback software. Alternatively, some charging bases with a network port may be preset, and the single police law enforcement audio and video recorder is inserted into the charging base by using a pin-type network port, and the charging base is connected to the server through the network port, thereby establishing a single police law enforcement audio and video recording. The connection between the instrument and the server. Regardless of the method used, the present invention eliminates the need to set up a collection station, which greatly reduces the cost.

[0063] In the embodiment of the present invention, the single police law enforcement audio and video recorder collects the first data, and sends the first data to the in-vehicle hard disk recorder; the in-vehicle hard disk recorder collects the second data, and the The second data and the received first data are sent to the monitoring server; the monitoring server receives and records Recording the first data and the second data; wherein the first data and the second data are associated by the identification information included in the data field. The above process establishes the communication relationship between the single police law enforcement audio and video recorder and the vehicle hard disk recorder, and saves the data collected by the single police law enforcement audio recorder and the vehicle hard disk recorder in the same monitoring server, and uses the identification information. Correlate data collected by different devices.
