Cold storage controller

The utility model discloses a cold storage controller, which is provided with a cold storage switch circuit 1, and a detection circuit 2, wherein, the cold storage switch circuit 1 is connected with a data collection circuit; the detection circuit 2 is connected with a signal processing circuit. The output of the data collection circuit and the signal processing circuit is connected with a microprocessor, and the output of the microprocessor is connected with a control-driven circuit 3. The output of the control-driven circuit is connected with an action element. Each cold storage is provided with switches and detection circuits, and the switches and the detection circuits can be used for reflecting the situations of the cold storage. Received signals are inputted to the set microprocessor to be processed. The utility model has the characteristics of integration, modularization, and latticing. The set microprocessor can be used for properly detecting indexes, such as temperature, humidity, running current of a blower, etc., and can also be used for controlling the blower, a liquid feeding valve, a defrosting valve, etc. according to detected index data to finally control the temperature, the humidity, etc. of the cold storage.
