Multifunctional controller for shutter door

The utility model relates to a multifunctional controller for a rolling gate, which can freely control the ascent, descent and stopping of a rolling gate even when urban electricity fails and belongs to a control device of the rolling gate. The multifunctional controller for a rolling gate is composed of a wireless remote control emitter, a wireless remote control receiving circuit, a manual ascending and descending control circuit, a power circuit, etc., and is characterized in that when urban electricity is normally supplied, an MPU central processing system controls a charging and discharging control circuit to charge an accumulator, and at the time of power failure, the MPU central processing system controls an inverting circuit so that the direct current voltage of the accumulator is converted to an alternating current voltage. Therefore, no matter urban electricity fails or not, the utility model can control the ascent, descent and stopping of the rolling gate in the manner of wireless remote control or manual control. The controller of the utility model also has the functions of anti-theft and anti-prizing alarm, community linkage, rise at the time of encountering obstacles, illumination with time delay, etc. The controller of the utility model has the advantages of unique conception, complete functions, easy application, simple operation, reliable work, high performance-price ratio, etc.
