摘　　要：针对电网GIS中多用户协同编辑的现实需要,在确保编辑数据一致性和正确性的基础上,结合任务划分和版本管理技术,提出了基于锁定机制的电网GIS多用户协同编辑.首先分析了协同编辑的体系结构和编辑流程,然后描述了协同编辑中锁定机制的实现算法、锁定流程以及客户端之间数据同步,最后结合实际项目需求构建原型系统,对基于锁定机制的电网GIS多用户协同编辑进行了验证.Aiming at the practical needs of multi-user collaborative editing in power grid GIS, a multi-user cooperative editing of power grid GIS based on locking mechanism is proposed based on the task division and version management technology to ensure the consistency and correctness of the edited data. This study first analyzes the architecture and editing process of collaborative editing. Then it focuses on the implementation of the locking mechanism in the collaborative editing, the locking process and the data synchronization between the clients. Finally, a prototype system is constructed based on the test data of a certain province, and it verifies the multi-user collaborative editing of power grid GIS based on locking mechanism.
