The dehumidification module is achieved by circulating the fan, and the fan is provided with an air outlet and an air inlet on the outer wall of each storage cabinet 8, and a dehumidification filter is provided at the air inlet. The circulating fan is provided at the air outlet. When the circulating fan is turned on, the air in the environment enters the storage cabinet 8 after being dehumidified by the dehumidification filter, realizing the dehumidification operation in the storage cabinet 8. In order to further reduce the cost, the circulating fan and the dehumidification filter can also be omitted, and a drying agent such as molecular sieve is provided in the storage cabinet 8, which realizes the control of the humidity in the storage cabinet 8 by regular replacement.

[0033] A touch screen is also connected to the input and output ports of the main controller. The temperature and humidity data in each storage cabinet 8 can be displayed and set through the touch screen.

[0035] The specific working process and working principle are as follows:

[0036] When the staff needs to take out the goods from the cabinet 1, the server sends the staff's identity, the type and quantity of the goods to the main controller before the staff arrives at the cabinet 1. After the staff arrives at the cabinet 1, the identity recognition module 4 performs identity recognition. After the recognition, the main controller controls the electric door lock 7 of the corresponding storage cabinet 8 to open. The staff closes the door after taking out the corresponding goods. Each opening and closing of the storage cabinet 8 door is recorded by the main controller and uploaded to the server through the communication module.

[0037] The main controller monitors the corresponding storage cabinet 8 through the temperature sensor and the humidity sensor in each storage cabinet 8, and when the temperature exceeds the set temperature, the main controller controls the temperature control module to cool the corresponding storage cabinet 8, so that the temperature reaches the preset temperature. For the monitoring of the humidity in the storage cabinet 8, when the humidity in the storage cabinet 8 exceeds the threshold value, the main controller notifies the corresponding staff to replace the amount of dehumidifier in it through the alarm or the server. Or the main controller controls the circulating fan in the storage cabinet 8 to work, when the circulating fan is opened, the air in the environment enters the storage cabinet 8 after being dehumidified by the dehumidification filter, realizing the dehumidification operation in the storage cabinet 8.

[0038] When the main controller identifies that smoke appears in the flammable material storage cabinet through the smoke sensor arranged in the flammable material storage cabinet, the main controller controls the electromagnetic valve 12 to open, drives the high-pressure gas in the gas cylinder 14 to drive the dry powder in the storage tank 10 to output, the dry powder enters the flammable material storage cabinet through the dry powder output pipeline 9, and is sprayed out by the spray head, realizing fire extinguishing. At the same time, the main controller controls the alarm to alarm, and sends the information to the server through the communication module.
