摘　　要：针对目前机动车检测行业中存在的计算机管理控制系统与检测仪器设备之间的双向交互数字接口因检测仪器的型号、规格不同而标准不一的问题,采用异步全双工工作方式的接口标准和数据校验方式,设计了一种规范的通信接口协议。根据机动车检测流程要求,重点介绍了通信接口协议的指令格式和功能,对机动车检测流程和检测仪器设备的状态进行了规范。统一通信接口协议的使用对确保检测数据的准确合理、规范机动车检测行业有重要的作用和深远的意义。The standards of the two-way interactive digital interface between the computer management control system and detecting equipments vary with detection equipment models and specifications in vehicle detection industry, it is deadly in need of a standard communication interface protocol. The authors put forward a detail format and function of the two-way interactive digital interface with full-duplex asynchronous serial mode of interface standards and data verification method. What＇s more, according to the requirements of motor vehicle testing process, it has been focused on the communication interface of the agreement features instruction and format to carry out the norms of the detection of motor vehicle testing processes and equipments. It is important and far-reaching significance for the vehicle detecting industry to use a standard two-way interactive digital interface.
