The method comprises: a second electronic control unit (ECU) in a gateway platform determines that the heartbeat of a bound first ECU is lost; and the second ECU provides a proxy service for a client by means of a second interface in communication with the client, wherein the priority of the second ECU is lower than that of the first ECU. According to the method, main and standby ECUs are determined in a priority mode; when the main ECU (i.e., the first ECU) fails, causing the heartbeat to be lost, it is switched to the standby ECU (i.e., the second ECU) to execute the proxy service, implementing service backup, service switching, and service recovery functions of a vehicle-mounted ECU general controller. The main-standby switching takes less time, and there is no need to build a plurality of ECUs locally, which can effectively reduce costs.

一种代理服务方法、装置及***Proxy service method, device and system
本申请要求于2020年04月26日提交中国专利局、申请号为202010339347.4、申请名称为“一种代理服务方法、装置及***”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。This application claims the priority of a Chinese patent application filed with the Chinese Patent Office on April 26, 2020, the application number is 202010339347.4, and the application name is "a method, device and system for agency services", the entire content of which is incorporated herein by reference Applying.
技术领域Technical field
本申请涉及通信技术领域，尤其涉及一种代理服务方法、装置及***。This application relates to the field of communication technology, and in particular to a proxy service method, device and system.
背景技术Background technique
随着车载行业的发展，电子控制单元(Electronic Control Unit，ECU)越来越多，车内网络也逐步向面向服务的通信演进。其中，代理服务在满足可靠性的同时，高效性和灵活性也越来越受到重视。With the development of the automotive industry, there are more and more electronic control units (ECUs), and the in-vehicle network is gradually evolving to service-oriented communication. Among them, while the agency service satisfies the reliability, the efficiency and flexibility have also been paid more and more attention.
为此，面向服务的架构(Service Oriented Architecture，SOA)创建了一个以明确定义的接口为特征的服务环境，环境中的软件组件可作为服务生产者或服务消费者，通过服务总线的中间件通信。如图1所示，服务提供者是一个提供功能的独立单元，用于发布服务；服务代理是一个服务注册中心，用于运行时查找服务，可以是分布式***；服务消费者通过服务代理查找服务，可以访问多个服务提供者。To this end, the Service Oriented Architecture (SOA) creates a service environment characterized by well-defined interfaces. The software components in the environment can be used as service producers or service consumers to communicate through the middleware of the service bus. . As shown in Figure 1, the service provider is an independent unit that provides functions and is used to publish services; the service agent is a service registry, which is used to find services at runtime, which can be a distributed system; the service consumers find through the service agent Service, you can visit multiple service providers.
其中，针对上述以接口为特征的服务环境，目前提供一种冗余ECU电路结构的控制器。如图2所示，在本地设置两个ECU，例如，ECUa与ECUb。其中，所述ECUa与ECUb之间相互连接，且所示冗余ECU电路结构的控制器主要通过输入电路冗余、CPU冗余来实现。具体的，当一个ECU在正常工作时，另一个ECU处于热备份状态，当ECU认为某一通道输入信号不可信时，可切换成从另一通道输入信号。同理，当某个CPU故障或不可信时，可切换成另一个CPU来控制设备。Among them, for the above-mentioned service environment characterized by interfaces, a controller with a redundant ECU circuit structure is currently provided. As shown in Figure 2, two ECUs are provided locally, for example, ECUa and ECUb. Wherein, the ECUa and the ECUb are connected to each other, and the controller of the redundant ECU circuit structure shown is mainly realized by input circuit redundancy and CPU redundancy. Specifically, when one ECU is working normally, the other ECU is in a hot backup state. When the ECU considers the input signal of a certain channel to be unreliable, it can switch to the input signal from another channel. In the same way, when a CPU fails or is untrustworthy, it can be switched to another CPU to control the device.
然而，图2所示的车载服务代理***，是一种点对点的备份，无法支持多对一备份，并且执行过程中需要自行处理主备逻辑控制，成本高，无法适用于车载ECU通用控制器。However, the in-vehicle service agent system shown in Figure 2 is a point-to-point backup and cannot support many-to-one backup. In addition, the main and backup logic control needs to be handled by itself during the execution process, which is costly and cannot be applied to the vehicle ECU general controller.
综上，目前并没有一种高效、灵活且安全的代理服务方案。In summary, there is currently no efficient, flexible and secure agency service solution.

其中，针对上述以接口为特征的服务环境，目前提供一种冗余ECU电路结构的控制器。如图2所示，在本地设置两个ECU，例如，ECUa与ECUb。其中，所述ECUa与ECUb之间相互连接，且所示冗余ECU电路结构的控制器主要通过输入电路冗余、CPU冗余来实现。具体的，当一个ECU在正常工作时，另一个ECU处于热备份状态，当ECU认为某一通道输入信号不可信时，可切换成从另一通道输入信号。同理，当某个CPU故障或不可信时，可切换成另一个CPU来控制设备。Among them, for the above-mentioned service environment characterized by interfaces, a controller with a redundant ECU circuit structure is currently provided. As shown in Figure 2, two ECUs are provided locally, for example, ECUa and ECUb. Wherein, the ECUa and the ECUb are connected to each other, and the controller of the redundant ECU circuit structure shown is mainly realized by input circuit redundancy and CPU redundancy. Specifically, when one ECU is working normally, the other ECU is in a hot backup state. When the ECU considers the input signal of a certain channel to be unreliable, it can switch to the input signal from another channel. In the same way, when a CPU fails or is untrustworthy, it can be switched to another CPU to control the device.
然而，图2所示的车载服务代理***，是一种点对点的备份，无法支持多对一备份，并且执行过程中需要自行处理主备逻辑控制，成本高，无法适用于车载ECU通用控制器。However, the in-vehicle service agent system shown in Figure 2 is a point-to-point backup and cannot support many-to-one backup.

Specifically, the embodiment of the present application addresses the problem that there is no efficient, flexible, and secure proxy service solution at present, and provides a priority method to determine the main and standby ECUs. When the main ECU (i.e., the first ECU) fails and the heartbeat is lost, it is replaced with a backup ECU (i.e., the second ECU) to perform proxy services, realizing the service backup, service switching, and service recovery of the vehicle-mounted ECU general controller At the same time, it takes less time to switch between active and standby, and there is no need to build multiple ECUs locally, which can effectively reduce costs.

That is, the interface for communicating with the client is the interface corresponding to the first ECU (for example, the interface corresponding to the first ECU is the second interface).
综上，通过上述配置，所述第一ECU与所述第一ECU对应的第二ECU具有相同的组ID，同组中的第一ECU的优先级高于第二ECU。此外，可选的，同组的所有ECU对应相同的虚拟IP。In summary, through the above configuration, the first ECU and the second ECU corresponding to the first ECU have the same group ID, and the first ECU in the same group has a higher priority than the second ECU. In addition, optionally, all ECUs in the same group correspond to the same virtual IP.
需要说明的是，本申请实施例中上述配置内容并不限定先后顺序，任何适用于本申请实施例的配置方式都属于本申请实施例保护范围。It should be noted that the foregoing configuration content in the embodiment of the present application does not limit the sequence, and any configuration method suitable for the embodiment of the present application belongs to the protection scope of the embodiment of the present application.
