THDS-100调度自动化系统中多线程技术的应用

为提高调度自动化系统的性能 ,以中、小型地调和县调为主要应用对象 ,结合 Windows NT操作系统多线程处理能力 ,利用多线程的特点及其优势 ,讨论了如何利用线程的优先级设置 ,使系统重要运行状况得到快速响应。同时比较了实现线程同步的几种方法 ,避免了数据的不一致。该技术已成功地应用于 THDS- 10 0调度自动化系统中 ,显示出明显的优越性。避免了常规定时器方式下时间的浪费。利用操作系统的线程调度功能管理调度自动化系统中不同功能的线程 ,使系统性能达到最高 ,并在故障处理时仍可以实现系统其他功能

Multithread technology in THDS-100 automatic dispatching system

The performance of an automatic dispatching system is analyzed for medium or small size dispatching systems and county dispatching systems. The system uses the multithread managing ability of the Windows NT operating system. The system analyzes how to utilize thread priority setting to increase the response of important system processes. At the same time, several methods are compared to synchronize threads and avoid inconsistent data. This technology has been successfully used in the THDS 100 Automatic Dispatching System with very good results. It avoids the waste of time in the general timer method. The method uses the multithread dispatching ability of the operating system to manage threads with different functions in the automatic dispatching system for better peak performance while performing other system functions during fault handling.
