Abstract
The utility model relates to a control system with double processors implemented by a power management device. Each of double processing systems comprises a processing unit, a shared display and a peripheral circuit. A main processing device with the powerful processing function is powered by an external power supply. A micro-power-consumption processing device is powered by the external power supply or an internal power supply selected by a power management device. When the external power supply operates normally, the two processing devices are powered by the external power supply and are coordinated to operate by serial or parallel communication. When the external power supply is cut off, the main processing device stops operating, the micro-power-consumption processing device is powered by the internal power supply selected by the power management device, and operations required for minimum normal operation of the controller are maintained until the external power supply restores. The contradiction between the requirement of the industry of electric actuators upon continuous improvement of control system processing capability and micro-power-consumption operation after power cutoff is overcome, a complete low-cost solution is provided for development and production of electric actuator and valve electric device control systems, and a simple and low-cost way is found.
