摘要
针对工业控制领域组态软件采集数据时高可靠性和高稳定性的要求，提出了一种简单有效、易于扩展、基于主从方式的双机热备软件解决方案，研究和解决了在双机热备系统中的控制权转换问题、实时数据和历史数据的备份以及同步问题等，通过编程实现了这一方案并取得了较好的实际运行效果。
Aiming at high reliability and stabilization of configuration software in industry control fields during gathering data, a simple, effective, extensible and based hot - switched backup solution is proposed. Furthermore, the conversion of control power, the backup of real - time and history data, synchronization problem and so on are all researched and solved. At last, by practical programming above scheme is implemented and preferable result is achieved.
