基于单片机的汽车雨刷测试平台设计

Design on Wlndshield Wipers Test Platform of Microcontroller

在完成了汽车雨刷测试系统的设计制作的基础上,介绍了嵌入式系统在测试系统的应用。系统采用单片机通过总线联接各个传感器和执行器,并通过USB接口与主机通讯。在执行前可以从主机获得执行任务,也可从内部的存储器中读取预存的任务执行。在执行过程中可以随时更改任务,而且,系统通过通讯接口将整个平台的状态实时地反馈到主机上,由主机通过合理的人机界面将信息反馈至用户。

Based on the successful design of a microcontroller system-the rainwiper testing system,this paper presents the application of embedded systems on testing and control.In this testing system,the sensors and the peripherals is connected to the microcontroller through buses,while the microcontroller communicates with the host computer through USB interface.The microcontroller system can either receive command from the host computer or read settings from its memory.Tasks can be switched by users when the system is running.In addition,the microcontroller system is able to feedback the states of peripherals to the host computer,thereafter such information is presented to the users through graphic user interface.
