摘要
PLC板级工装测试系统主要对N系列全国产化PLC单板模块的硬件连通性及其基本功能进行测试,为简单硬件设计及问题查找定位提供软件支持与验证。一般的板级工装测试产品,不同板卡测试环境不同,操作复杂,且大部分是手动测试,人力物力成本太高。提供一种基于Qt的跨平台PLC板级工装测试方法与系统,是对PLC单板模块功能及接口的自动化测试系统。实际测试表明,该系统可以大幅度提高测试效率,节约测试成本。
Programmable Logic Controller(PLC) board-level tooling test system, designed to test the single-board hardware connectivity and basic functions of N series PLC which was localized, it provided software support and verification for simple hardware design and problem locating. General board-level tooling test products whose testing environment was different for each board, even the manual operation was complicated that lead to human and material costs are too high. This paper provided a cross-platform PLC board-level tooling test method and system based on Qt, which was a automated test system for single-board PLC module function and interface. The results show that the system can increase efficiency and cut the cost greatly.
