摘　　要：为实际测试板载继电器是否能够达到使用期限的要求,提高板载继电器产品的稳定性和可靠性,设计基于嵌入式的板载继电器寿命测试系统对板载继电器的机械寿命和电气寿命进行测试。在系统结构方面,分为下位机和上位机两部分,下位机以嵌入式系统为基础,通过主控模块完成对板载继电器的驱动及外围逻辑电路的搭建,对动作过程中待测继电器的接点状态进行采集并将故障信息进行编码,通过RS-232通信方式将故障编码信息传输给上位机。上位机采用C#编程语言进行设计,具有对故障编码信息进行存储、分析与显示等功能。最后,通过系统联调实验验证此系统在信息采集、数据通信以及故障诊断等方面的可行性和实用性。In order to actually test whether the onboard relay can meet the requirements of the service life and improve the stability and reliability of the onboard relay products,an embedded onboard relay life test system is designed to test the mechanical and electrical life of the on-board relay.In terms of system structure,it is divided into two parts:the lower computer and the upper computer.Based on the embedded system,the lower computer completes the drive of the onboard relay and the construction of the peripheral logic circuit by way of the main control module,collects the contact state of the relay to be measured in the process of action and codes the fault information,and transmits the coded fault information to the upper computer through RS-232 communication.The upper computer is designed with C#programming language,and has the functions of storing,analyzing and displaying the coded fault information.Finally,the feasibility and practicability of the system in information acquisition,data communication and fault diagnosis are verifi ed through system joint debugging.
