摘　　要：本文介绍了轨道交通通用I／O装置的研制方法,该装置采用模块化方法设计,可根据需要灵活配置各模件数量.基于80296SA控制CPU设计,PLC模块能实现在线实时组态、完成各种逻辑闭锁控制。装置真正实现可编程(PLC)控制功能与传统测控功能完全融合。灵活性和可扩展性大大提高、具有很好的应用前景。An universal I/O equipment of 80296SA microprocessor rail transportation is introduced . It is designed by modularization, and each module can be flexibly configured according to different requirements. Also the PLC module can be configured on line in real time , finishing various logic control. It genuinely completes the integrity of the PLC control function and the traditional measurement and control function. With the flexibility and extensibility greatly improved, it has a very good application future.
