摘要： 在分布式组态系统中，各终端上的组态文件可能存在不一致问题。该文设计一种基于集群系统的组态文件分布式锁。使用互斥方法实现对组态文件的修改，保证多终端上组态文件的一致性。采用激活数据包的方法避免接收请求被阻塞，保证了整个系统的可靠性和稳定性。

Abstract: There are perhaps different configuration files in the terminals in distributed configuration system. This paper designs a configuration file Distributed Lock based on the assembled system. It uses incompatible method to revision configuration files, and keeps the coherence of configuration files in all the terminals. Activation data packet is used to avoide the receiving request being blocked blocked, and to keep the reliable and stability of all the system.

Key words: component-based software, distributed lock, incompatible
