[0032] 为了说明本发明所述的技术方案, 下面通过具体实施例来进行说明。  [0032] In order to explain the technical solution described in the present invention, the following description will be made by way of specific embodiments.
[0033] 实施例 1 Embodiment 1
[0034] 请参阅图 1, 示出了本发明实施例中一种数据记录方法, 应用于包括单警执法 视音频记录仪、 车载硬盘录像机和监控服务器的系统, 所述单警执法视音频记 录仪和所述车载硬盘录像机无线连接, 所述车载硬盘录像机和所述监控服务器 无线连接。  [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] 单警执法视音频记录仪是一种便于随身携带的音视频记录设备, 广泛应用于执 法部门, 比如警察等城市管理人员执勤吋使用。 车载硬盘录像机主要用于车辆 的安全监控, 对于执法部门来说一般将其用于对执法现场进行全方位的音视频 监控。 由于单警执法视音频记录仪和车载硬盘录像机采取的硬件编解码的方案 不同, 因此一直以来都是作为两种不同的产品单独应用, 目前并不存在将二者 集成的系统。 然而, 在进行数据回放吋, 执法人员需要从不同的设备搜索相关 的数据, 操作十分不便。  [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] 有鉴于此, 本发明实施例提供了一种数据记录方法、 系统、 视音频记录仪和车 载硬盘录像机, 旨在解决将单警执法视音频记录仪和车载硬盘录像机所记录的 数据进行数据回放吋操作不便的问题。  [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] 本发明实施例的数据记录方法包括:  [0037] The data recording method of the embodiment of the present invention includes:
[0038] 101、 所述单警执法视音频记录仪采集第一数据, 并将所述第一数据发送至所 述车载硬盘录像机;  [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] 所述单警执法视音频记录仪可以是一个, 也可以是多个, 所述第一数据可以是 音频、 视频、 文字和图像等各种类型的数据。 单警执法视音频记录仪和车载硬 盘录像机之间通过无线网络进行连接, 比如 WIFI或者蓝牙, 当某个单警执法视 音频记录仪连接到车载硬盘录像机之后, 可以将其视作车载硬盘录像机的其中 一个普通的视频通道, 即实现了二者的无缝集成。 当单警执法视音频记录仪与 车载硬盘录像机通讯连接吋, 单警执法视音频记录仪会将自己采集到的数据传 输给车载硬盘录像机进行保存, 使得车载硬盘录像机在数据回放吋, 能将通过 自身的视频通道采集的数据和接收到的由单警执法视音频记录仪发送的数据一 起进行回放, 实现关联数据的同步回放。 [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] 基于单警执法视音频记录仪需要传输视频等较大的数据至车载硬盘录像机, 它 们之间优选采用 WIFI进行连接。 然而, WIFI连接同样具有一定的局限性, 比如 容易受到各种信号干扰。 当单警执法视音频记录仪和车载硬盘录像机中断连接 吋, 单警执法视音频记录仪将独立采集数据, 等重新连接后, 单警执法视音频 记录仪再将未发送的数据发送给车载硬盘录像机进行保存。  [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] 进一步的, 为了提高通信的稳定性, 所述单警执法视音频记录仪和所述车载硬 盘录像机通过 2.4G/5G双频段设计的 WIFI连接, 所述数据记录方法还可以包括: [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] 所述单警执法视音频记录仪获取现场的环境信息和信号干扰强度, 所述环境信 息包括阻碍 WIFI信号传输的障碍物的体积; [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] 当所述阻碍 WIFI信号传输的障碍物的体积大于第一阈值或者所述信号干扰强度 小于第二阈值吋, 所述单警执法视音频记录仪通过 2.4G频段的 WIFI信号与所述 车载硬盘录像机连接;  [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] 当所述阻碍 WIFI信号传输的障碍物的体积小于第一阈值或者所述信号干扰强度 大于第二阈值吋, 所述单警执法视音频记录仪通过 5G频段的 WIFI信号与所述车 载硬盘录像机连接。  [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] 对于 2.4G频段的 WIFI信号来说, 其穿透障碍物的能力强, 但由于大量设备都是 用此频段的信号, 受到的信号干扰较多。 而对于 5G频段的 WIFI信号来说, 其穿 透障碍物的能力差, 但受到的信号干扰较少。 因此, 根据现场的环境信息和信 号干扰强度对单警执法视音频记录仪和所述车载硬盘录像机之间的 WIFI信号频 段进行切换, 能够有效提高通信连接的稳定性。  [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] 进一步的, 所述数据记录方法还可以包括:  [0046] Further, the data recording method may further include:
[0047] 所述单警执法视音频记录仪获取出勤登记信息, 并将所述出勤登记信息发送给 所述车载硬盘录像机。  [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] 在现有技术的车载硬盘录像机中, 一般需要设计一套 UI, 或采用 RFC刷卡等类 似的考勤设备与软件功能, 相关人员在出勤吋需要先在车载硬盘录像机上进行 登记。 然而, 采用这种方式很可能存在相关人员忘记在车载硬盘录像机上进行 登记的情况。 而在本发明实施例中, 相关人员即使忘记在车载硬盘录像机上进 行登记, 仍可通过随身携带的单警执法视音频记录仪输入出勤登记信息, 由单 警执法视音频记录仪自动在车载硬盘录像机上进行出勤登记, 能够避免漏打出 勤登记造成的证据不完整现象。 [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、 所述车载硬盘录像机采集第二数据, 并将所述第二数据和接收到的所述 第一数据发送至所述监控服务器;  [0049] 102. The in-vehicle DVR collects second data, and sends the second data and the received first data to the monitoring server.
[0050] 所述第二数据是所述车载硬盘录像机通过自身的视频通道采集的任意数据, 一 般为数据采集现场的音视频数据。 所述监控服务器是一个远程的终端服务器, 比如可以是执法中心内带有相关应用软件的系统平台。 车载硬盘录像机和监控 服务器之间通过无线网络进行连接, 比如 WIFI、 3G或者 4G等。 车载硬盘录像机 能够实吋将自身存储的数据上传至监控服务器, 包括自身采集的第二数据以及 从单警执法视音频记录仪获取的第一数据。  [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、 所述监控服务器接收并记录所述第一数据和第二数据。  [0051] 103. The monitoring server receives and records the first data and the second data.
[0052] 所述监控服务器能够接收并记录所述车载硬盘录像机上传的所述第一数据和第 二数据, 还可以对车载硬盘录像机和单警执法视音频记录仪进行实吋监控, 实 现远程指挥, 整体把控现场情况。 其中, 所述第一数据和第二数据通过数据字 段中包含的标识信息关联。 具体的, 所述标识信息可以是车载硬盘录像机和单 警执法视音频记录仪所采集到的数据的共同信息, 比如可以包括执法人员编号 、 设备编号、 车牌号和吋间等信息。 通过标识信息将不同设备采集的数据进行 关联之后, 监控服务器能够准确区分每个事件对应的各个不同数据, 形成每个 事件的完整数据链。  [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] 具体的, 所述第一数据和第二数据可以通过以下步骤进行关联:  [0053] Specifically, the first data and the second data may be associated by using the following steps:
[0054] 所述车载硬盘录像机在接收到所述第一数据后, 获取所述第一数据的标识信息 , 将已采集到的所述第二数据中标识信息与所述第一数据的标识信息之间符合 一定条件的第二数据与所述第一数据进行关联。  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] 若第一数据的标识信息和第二数据的标识信息符合一定的条件, 则说明第一数 据和第二数据是相互关联的。 所述一定的条件可以是标识信息完全相同, 或者 是标识信息包含部分相同的内容, 比如可以将执法人员编号和车牌号都相同的 不同数据进行关联, 或者将采集吋间相同的不同数据进行关联。 [0056] 进一步的, 所述数据记录方法还可以包括: [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] 所述监控服务器在获取到数据回放指令后, 将关联的所述第一数据和第二数据 在同一个显示界面中展示。  [0057] After acquiring the data playback instruction, the monitoring server displays the associated first data and second data in the same display interface.
[0058] 在数据回放阶段, 相关人员可以在所述监控服务器上输入数据回放指令, 即可 在同一个显示界面中观看与指定事件关联的所有数据。 在实际应用中, 可以将 终端的显示界面划分为多个显示区域, 每个显示区域显示指定设备采集的指定 数据, 各个显示区域在同一吋间段显示的内容可以是相互关联的数据。 比如将 某个指定事件相关的, 由单警执法视音频记录仪或车载硬盘录像机采集的, 且 位于指定吋间段内的所有音频、 视频、 定位信息、 事件标记和文字描述等数据 在同一个显示界面中展示, 便于相关人员对该指定事件进行调査。  [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.

[0061] 现有技术的单警执法视音频记录仪在将数据上传到服务器吋, 一般先通过 USB 接口接入采集站, 再由采集站将数据通过网口连接等方式上传到服务器。 虽然 u[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
SB接口比较通用, 但通过 USB接入可能出现无法识别设备的问题, 而且设置采 集站的成本也较高。 当单警执法视音频记录仪成功与服务器建立连接关系后, 单警执法视音频记录仪相当于服务器的一个普通的存储介质, 因此服务器还需 要安装对应的数据回放软件对单警执法视音频记录仪采集的数据进行回放。 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] 而在本发明实施例中, 所述单警执法视音频记录仪能够直接与服务器进行通讯 , 比如可以通过 WIFI直接与服务器连接, 服务器即可通过 IP地址访问单警执法 视音频记录仪, 然后即可通过浏览器等方式对单警执法视音频记录仪的数据进 行回放, 无需安装数据回放软件。 或者, 也可以预设一些带有网口的充电底座 , 单警执法视音频记录仪采用针脚式的网口插入充电底座, 充电底座再通过网 口接入服务器, 从而建立单警执法视音频记录仪和服务器的连接。 无论采用何 种方式, 本发明都无需设置采集站, 大大降低了成本。  [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.
