The invention discloses an industrial and mineral JP cabinet intelligent constant temperature system including a JP cabinet body, a refrigeration and heating device, an internal heat exchanger, an external heat exchanger, a first driving oil pump, a second driving oil pump, and a plurality of temperature sensors, the refrigeration and heating device, the internal heat exchanger, the first driving oil pump, the second driving oil pump, and the plurality of temperature sensors are arranged in the JP cabinet body, an external heat exchanger is arranged at the outer side of the JP cabinet body, and the refrigeration and heating device includes a heating device, a refrigerator, a controller, a plurality of groups of semiconductor refrigeration sheets, and a casing. The industrial and mineral JP cabinet intelligent constant temperature system acquires the temperature signal in the JP cabinet through the temperature sensors, the controller controls the on and off of the first driving oil pump and the second driving oil pump based on the temperature signal, and moreover, the controller controls the flow direction of the oil medium in the interface pipe and the switching of the semiconductor refrigeration sheets according to the temperature signal and reliably ensures the constant temperature in the JP cabinet.
