Embedded device business logic visual display method

The invention relates to an embedded device business logic visual display method, belonging to the technical field of relay protection in electric power engineering. The method adopts a mode, in which a built-in script engine loads an external business logic script. The script engine performs business logic combined transformation and display according to a control information message receiving a request; when the business combination logic changes, current element control information is refreshed and display positions of all basic elements in currently visible clusters, blocks and groups are adjusted dynamically; and full screen redrawing is enforced to carried out, and if a control information set is not changed, the former state of the element is erased and a new state of the element is drawn. According to the method, under the condition of no modification on a software code, flexible requirements of business modules can be realized through change of the business logic script; and real-time combined transformation of the business logic is controlled by blocking and deblocking of the business control data, and requirements of stability, rapidness, flexibility and universality can be met at the same time.
