Abstract: The conventional way of manually filling in the switching operation ticket takes up a lot of human resources when dealing with simple and repetitive operations. In order to solve this problem, combined with the characteristics of standardized terms, fixed steps and simple sentences of substation switching operation ticket, this paper proposes an automatic generation method of substation switching operation ticket based on binary tree storage structure. This method stores the scheduling order into the computer in a queue data structure, and obtains the switching operation content through the queue traversal algorithm; The primary system diagram of the substation is stored in the computer with binary tree data structure to digitize the primary system diagram; Enter the typical operation ticket into the database in an exhaustive manner. Finally, obtain the operation task by analyzing the dispatching order, compare the operation task with the digitized primary system diagram, and finally determine the typical operation ticket, and retrieve the corresponding switching operation ticket from the database. The program operation proves that this method realizes the automatic generation of substation switching operation ticket.
