摘要
EPICS分布式控制系统提供一种Callback机制,实现网络协议和设备驱动中的异步处理,在设备数据或状态变化时设备驱动才读取数据,并传输到网络,减轻网络通讯负荷和控制器CPU负载。本文分析了EPICS的Callback机制,并建立一个用Callback处理中断方式I/O的ADC数据采集的软件开发系统。
The callback task in EPICS realizes asynchronous process in network transferring and device driver. In the asynchronous processing, only the data changed by device driver are collected, and transferred on the network. It alleviates the burden of both networks and the CPU load of IOC. In this paper, we analyze the callback task in EPICS, and introduce how to set up an ADC system with interrupt and callback.
