Description

中心式ECU开发测试系统 技术领域
本发明属于ECU开发测试技术领域，尤其涉及一种中心式ECU开发测试系统。
背景技术
汽车电子控制单元ECU在开发及测试过程中，需要大量的开发及测试人员，而每一位技术人员通常需要同时对多个ECU进行开发及测试工作，这就导致了大量的ECU、下位机VCI(Vehicle Connection Interface)及线束堆积在办公区域，设备管理混乱，且容易发生电路安全事故。
现有的ECU开发及测试台架多是单一个体台架，摆放于技术人员工作台，线束较多，不利于统一规范管理，每个台架可能都配置了相同数量的ECU，这种重复配置利用率低、成本高，或是多个ECU集中放置在周边的架子上，技术人员测试不同ECU时，需要到架子旁手工进行设备的切换，操作复杂，且容易出错。
发明内容
基于此，针对上述技术问题，提供一种中心式ECU开发测试系统。

c、响应于用户输入的结束指令，向程控电源15发送第二指令，向交换机13发送第三指令，第二指令中具有第一端口号，第三指令中具有第二端口号。
在具体的应用场景下，用户可以在上位机11的操作界面中选择ECU标识，多个ECU标识可以列表的形式展示给用户，不同的ECU标识对应不同的ECU。同样，用户可以在上位机11的操作界面中输入结束指令，如按下结束按钮。
