The invention discloses an intelligent safety tool cabinet and a constant temperature and humidity control method thereof. The cabinet comprises a total controller, a cabinet body, a temperature sensor outside the cabinet body and a humidity sensor outside the cabinet body which are arranged outside the cabinet body, an internal temperature sensor, a temperature sensor and an internal humidity sensor inside the cabinet body and a temperature and humidity control box on the cabinet body; the temperature and humidity control box is provided with a constant temperature and humidity device, a ventis formed in the temperature and humidity control box, and an air flow control device is arranged on the vent; the cabinet body is communicated with the outside through the vent; the temperature sensor is connected to an air flow control device through a lever; the total controller is electrically connected with the temperature sensor outside the cabinet body, the humidity sensor outside the cabinet body, the internal temperature sensor, the internal humidity sensor and the constant temperature and humidity device. The cabinet has the advantages of adjusting the temperature and humidity in the safety tool cabinet through the constant temperature and humidity device, so that a safety tool is kept within a suitable temperature range; remote real-time monitoring of the safety tool cabinet isachieved.
