Automatic Test System Based on TEDS and Matric Switch Technology

摘要:

为了解决现有测试系统测试周期长,测试效率低的不足,在自动测试系统(automatic test system,ATS)的基础上,将电子数据表格(transducer electronic data sheets,TEDS)和改进的矩阵开关技术应用于系统中,对现有操作模式中存在的不足进行弥补,实现了传感器特征参数信息的自动读取以及测试资源和被测对象(unit under test,UUT)之间的高效匹配;给出了改进后系统的体系架构,研究了构建系统所需的关键技术,并进行了仿真试验;结果表明,改进后的系统有效解决了现有测试系统中存在的突出问题。

Abstract:

Aiming at the problem of disadvantages of low efficiency and long test cycle in the existing test system, to design an automatic test system(ATS) based on the Transducer Electronic Data Sheets TEDS and matric switch technology. The ATS achieves the function of the automatic reading of the sensor TEDS, the atomatic switch of the testing channels and the efficient matching of the test resources and tasks. The paper devise the structure of the ATS, the key technology of the ATS, and offer the experience for the compare with other types of the ATS. The result indicates that the system efficiently solve the problems of the existing ATS.
