In order to simplify the unified signing and payment process of material procurement in power enterprises and improve the efficiency of business processing, a visual control method for unified signing and payment process of material procurement in power enterprises is proposed. According to the business process of uniform signature and uniform payment for material procurement in power enterprises, the visual control structure of uniform signature and uniform payment business process is constructed by using the model view controller (MVC) pattern, and the visual transformation control of uniform signature and uniform payment business process is realized; The business logic layer calls the information of the database layer, completes the business process modeling of the unified signing and payment of the material purchase of the electric power enterprise based on the Petri net, and realizes the management and operation of various users, businesses and data; Under the function of the controller, the user layer selects the corresponding model from the business logic layer to respond to the user operation, and visually presents the control results of the unified signing and payment process. The experimental results show that this method can intuitively grasp the overall business process and the completion degree of each link, improve the work efficiency of each department, reduce the business processing time, and control the operational risk.
