Abstract
In order to satisfy the requirements of an electric actuating mechanism and a valve electric device for the strong processing capacity of a controlling system and micro power consumption work after electricity is cut off, the present invention uses a structure of a dual processing and dual displaying system. The dual processing system is composed of a processor, a display and a peripheral circuit. The electricity of a main processing system with a strong processing function is supplied by an outer power supply, and a micro power consumption processing system is that the outer power supply is chosen by a power supply managing device or the electricity is supplied by an inner power supply. When the outer power supply is normal, teamwork is carried out between two systems through serial or parallel communication, and the electricity of the outer power supply is supplied. When the electricity of the outer power supply is cut off, a main system stops working, a micro power consumption system is chosen by the power supply managing device, and the electricity of the inner power supply is supplied. The necessary operation of the minimum normal work of a controller is maintained until the outer power supply is restored. Consequently, the present invention solves the contradiction between the requirement of enhancing the processing capacity of the controlling system and micro power consumption work after the electricity is cut off in industry and finds a simple and low cost approach for the research development and the production of the electric actuating mechanism and the valve electric device.
