值得说明的是，本发明实施例所述的车载软件版本信息同步方法可以由车辆中的车载终端执行实现，所述车载终端是车辆监控管理系统的前端设备，集成了数据处理和数据通信等多项功能，具有强大的业务调度功能和数据处理能力。所述外部终端设备可以是汽车诊断仪或其他能够对车辆中的车载软件进行更新的设备。It is worth noting that the method for synchronizing on-board software version information according to the embodiment of the present invention can be implemented by an on-board terminal in the vehicle. It has powerful business scheduling functions and data processing capabilities. The external terminal device may be a car diagnostic instrument or other device capable of updating the on-board software in the vehicle.
当所述外部终端设备对车辆中的车载软件进行本地更新时，车载终端响应于所述外部终端设备对车辆的车载软件更新而产生的软件刷新事件，此时车载终端获取所述外部终端设备对所述车载软件更新后的车载软件版本信息，最后将所述车载软件版本信息上传至服务器进行保存，使得服务器及时地进行车载软件版本信息的同步。本发明实施例在服务器需要同步车载软件版本信息时无需周期性的查询车载软件版本信息，而是当车载软件有更新时直接获取对应的车载软件版本信息，不用过多占用车载终端发送与接收信息的资源并节省了网络流量。When the external terminal device locally updates the in-vehicle software in the vehicle, the in-vehicle terminal responds to a software refresh event generated by the external terminal device for updating the vehicle's in-vehicle software. The updated in-vehicle software version information of the in-vehicle software is finally uploaded to the server for storage, so that the server can synchronize the in-vehicle software version information in a timely manner. In the embodiment of the present invention, when the server needs to synchronize the on-board software version information, it is not necessary to periodically query on-board software version information, but directly obtain the corresponding on-board software version information when the on-board software is updated, without occupying too much the on-board terminal to send and receive information resources and save network traffic.
具体的，在步骤S1中，所述监测外部终端设备对车辆的车载软件更新而产生的软件刷新事件，包括：Specifically, in step S1, the monitoring of the software refresh event generated by the update of the vehicle's in-vehicle software by the external terminal device includes:
S11、监测车载网络中的操作报文；其中,所述操作报文为所述外部终端设备在对车辆进行操作时由车辆产生的；S11. Monitor the operation message in the vehicle network; wherein, the operation message is generated by the vehicle when the external terminal device operates the vehicle;
S12、当监测到所述操作报文且检测到该报文中携带有软件刷新事件识别码时，判定监测到软件刷新事件的发生。S12. When the operation message is monitored and it is detected that the message carries a software refresh event identification code, it is determined that the occurrence of a software refresh event is monitored.
具体的，当车辆中有车载软件在进行更新时车辆会产生携带有软件刷新事件识别码的报文，从而通过监测在车载网络中的操作报文，能够确定是否监测到软件刷新事件的发生。Specifically, when there is in-vehicle software in the vehicle that is being updated, the vehicle will generate a message carrying the software refresh event identification code, so that by monitoring the operation messages in the in-vehicle network, it can be determined whether the occurrence of the software refresh event is monitored.
优选的，所述监测车载网络中的操作报文后，在所述当监测到所述操作报文且检测到该报文中携带有软件刷新事件识别码前，还包括：当监测到所述操作报文且检测到该报文中的头部携带有诊断报文识别码时，判定当前报文为诊断报文；此时认为检测到诊断仪操作事件，即所述外部终端设备正在操作车载ECU。则步骤S12具体包括：当检测到所述诊断报文中携带有软件刷新事件识别码时，判定监测到软件刷新事件的发生。优选的，所述车载网络与所述车载终端采用UDS协议进行通信，所述诊断报文识别码为7或1。当然，该诊断报文识别码也可以是其他值，此处不做一一赘述。Preferably, after the monitoring of the operation message in the in-vehicle network, before the operation message is monitored and it is detected that the message carries the software refresh event identification code, the method further includes: when the operation message is detected. When operating the message and detecting that the header of the message carries the diagnostic message identification code, it is determined that the current message is a diagnostic message; at this time, it is considered that a diagnostic instrument operation event is detected, that is, the external terminal device is operating the vehicle ECU. Then, step S12 specifically includes: when it is detected that the diagnostic message carries the software refresh event identification code, it is determined that the occurrence of the software refresh event is monitored. Preferably, the in-vehicle network communicates with the in-vehicle terminal using a UDS protocol, and the identification code of the diagnostic message is 7 or 1. Of course, the diagnostic message identification code may also be other values, which will not be described in detail here.
在判定所述当前报文为诊断报文后，因所述诊断报文涵盖了常规诊断事件和软件刷新事件，因此需要进一步判断所述诊断报文是否表示有软件刷新事件的发生。此时，通过判断所述操作报文是否携带有软件刷新事件识别码来确定是否监测到软件刷新事件的发生。优选的，所述软件刷新事件识别码为“6E F1 84”，即此时所述操作报文可以为“7XX XX6E F1 84 XX XX XX XX”。值得说明的是，所述软件刷新事件识别码还可以更换成软件刷新流程中的其它识别码，该软件刷新事件识别码也可以设定为其他值，只要能够唯一识别软件刷新事件即可，都在本发明的保护范围内。After it is determined that the current message is a diagnostic message, since the diagnostic message covers a conventional diagnostic event and a software refresh event, it is necessary to further determine whether the diagnostic message indicates the occurrence of a software refresh event. At this time, it is determined whether the occurrence of the software refresh event is monitored by judging whether the operation message carries the software refresh event identification code. Preferably, the software refresh event identification code is "6E F1 84", that is, the operation message at this time may be "7XX XX6E F1 84 XX XX XX XX". It is worth noting that the software refresh event identification code can also be replaced with other identification codes in the software refresh process, and the software refresh event identification code can also be set to other values, as long as the software refresh event can be uniquely identified. within the protection scope of the present invention.
具体的，在步骤S2中，所述响应于监测到所述软件刷新事件，获取所述外部终端设备对所述车载软件更新后的车载软件版本信息，包括：Specifically, in step S2, in response to monitoring the software refresh event, obtaining the in-vehicle software version information after the in-vehicle software is updated by the external terminal device, including:
S21、响应于监测到所述软件刷新事件，向所述服务器上传与所述软件刷新事件对应的更新识别信息；S21. In response to monitoring the software refresh event, upload update identification information corresponding to the software refresh event to the server;
S22、接收所述服务器根据所述更新识别信息而发送过来的软件版本信息获取指令，并根据所述软件版本信息获取指令获取所述外部终端设备对所述车载软件更新后的车载软件版本信息。S22: Receive a software version information acquisition instruction sent by the server according to the update identification information, and acquire in-vehicle software version information after the in-vehicle software is updated by the external terminal device according to the software version information acquisition instruction.
优选的，所述车载软件为ECU软件，所述更新识别信息为车辆上所述车载ECU发生更新的ECU的识别码。进一步的，所述车载软件发生更新的ECU的识别码可以为所述操作报文中携带ECU的识别码，比如所述ECU的识别码为所述操作报文中的“7XX”。参见表1，表1为所述软件刷新事件的格式定义。Preferably, the in-vehicle software is ECU software, and the update identification information is an identification code of an ECU on the vehicle where the in-vehicle ECU is updated. Further, the identification code of the ECU whose in-vehicle software is updated may be the identification code of the ECU carried in the operation message, for example, the identification code of the ECU is "7XX" in the operation message. Refer to Table 1, which defines the format of the software refresh event.
表1软件刷新事件的格式定义Table 1 Format definition of software refresh event
优选的，步骤S21具体包括：Preferably, step S21 specifically includes:
S211、响应于监测到所述软件刷新事件，将预设的标志位置为第一值，并获取及保存与所述软件刷新事件对应的更新识别信息；S211, in response to monitoring the software refresh event, set a preset flag position as a first value, and acquire and save the update identification information corresponding to the software refresh event;
S212、响应于监测到所述标志位置为第一值，向所述服务器上传与所述软件刷新事件对应的更新识别信息，并将所述标志位置为第二值。S212. In response to monitoring that the flag position is a first value, upload update identification information corresponding to the software refresh event to the server, and set the flag position to a second value.
具体的，所述标志位为flag，所述第一值为1，所述第二值为0。当响应于监测到所述软件刷新事件时，将flag置为1，并获取及保存与所述软件刷新事件对应的更新识别信息；响应于监测到flag为1时，向所述服务器上传与所述软件刷新事件对应的更新识别信息，并将flag置为0。Specifically, the flag bit is flag, the first value is 1, and the second value is 0. When the software refresh event is detected in response to monitoring, the flag is set to 1, and the update identification information corresponding to the software refresh event is obtained and saved; in response to the flag being 1, the server uploads the relevant information to the server. The update identification information corresponding to the software refresh event described above is set, and the flag is set to 0.
在本实施例中，在监测到软件刷新事件后，通过获取及保存与对应的更新识别信息并将标志位置为第一值，这样即使车辆发生意外事故(例如车辆当前与服务器不能正常联网，或者车辆非正常下电等)，在车辆恢复正常后，依然可以立即响应于监测到所述标志位置为第一值，并及时向所述服务器上传与所述软件刷新事件对应的更新识别信息，有效确保服务器最终能够同步更新车载软件的更新版本信息。In this embodiment, after the software refresh event is detected, the corresponding update identification information is obtained and saved and the flag position is set as the first value, so that even if the vehicle has an accident (for example, the vehicle cannot be connected to the server normally, or abnormal power-off of the vehicle, etc.), after the vehicle returns to normal, it is still possible to immediately respond to monitoring that the position of the flag is the first value, and upload the updated identification information corresponding to the software refresh event to the server in time, effectively Make sure that the server can finally synchronize the updated version information of the in-vehicle software.
优选的，检测所述标志位的时机设定为：在整车上电时。具体的，考虑到实时性，在获取到所述更新识别信息后，可以立即将所述更新识别信息上传至服务器。但是每次车载终端与服务器之间建立连接都会使用流量，若是在车载终端获取到所述更新识别信息后立即上传至服务器，则需要多次建立车载终端与服务器之间的连接，会浪费车载终端的流量。因此，为达到省流目的，可以在整车上电时，才将所述更新识别信息发送给所述服务器，因车辆在每次上电启动时，都需要将国标数据上传到服务器，因此可以在上传国际数据的同时将所述更新识别信息上传至服务器，从而节省车辆流量。Preferably, the timing for detecting the flag bit is set as: when the whole vehicle is powered on. Specifically, considering the real-time nature, after the updated identification information is acquired, the updated identification information may be uploaded to the server immediately. However, traffic is used every time a connection is established between the vehicle-mounted terminal and the server. If the updated identification information is uploaded to the server immediately after the vehicle-mounted terminal obtains the information, the connection between the vehicle-mounted terminal and the server needs to be established multiple times, which will waste the vehicle-mounted terminal. traffic. Therefore, in order to achieve the purpose of saving traffic, the updated identification information can be sent to the server when the whole vehicle is powered on. Because the national standard data needs to be uploaded to the server every time the vehicle is powered on and started, it can be The updated identification information is uploaded to the server when the international data is uploaded, thereby saving vehicle traffic.
在整车上电时，监测所述标志位，当所述标志位置为第一值时，此时表明在整车上电前已经发生有软件刷新事件，需要向所述服务器上传与所述软件刷新事件对应的更新识别信息；当所述标志位置为第二值时，此时表明在整车上电前并未发生有软件刷新事件。When the whole vehicle is powered on, the flag bit is monitored.
