摘要
为有效处理协同虚拟维修针对同一对象的并发行为,完成维修操作,提出了动态权限分配方案。在维修任务开始前规划维修工步,根据各维修工步特点动态分配操作权限。给出了多人协同维修中动态操作权限的分配和回收思路,讨论了在仿真维修过程中保证维修人员状态唯一性的方法。利用着色Petri网对动态权限分配过程进行仿真,并从系统通信压力及控制难度两个方面与一次性权限分配方法进行比较,得到动态分配权限方法的优势所在。
In order to effectively deal with the concurrent behavior of cooperative virtual maintenance for the same object, a dynamic allocation scheme was proposed to complete the maintenance operation. Before the maintenance task was started, the maintenance steps were planned, and the operation rights were allocated dynamically according to the characteristics of each maintenance step. The idea of allocation and recovery of dynamic operation rights were proposed in multi person cooperative maintenance, discussing the method of ensuring the state uniqueness of maintenance personnel in the process of simulation maintenance. The process of dynamic rights allocation was simulated by colored Petri nets. Compared with the one-time permission allocation method from two aspects of system communication pressure and control difficulty, the advantage of dynamic allocation privilege method was obtained.
