[0049] Central control unit 3: the central control unit 3 is in wireless communication with humidity detection unit 11 and dehumidification equipment 2, which can control the direction of dehumidification port of dehumidification equipment 2 and dehumidification equipment 2 according to the humidity detected by humidity detection unit 11 at different detection points.

[0050] The present system can set up humidity detection equipment in different positions according to the size of indoor space, detect the humidity of all space positions in the room, and accurately control the humidity of different positions in the room.

[0051] It is worth mentioning that the humidity detection unit 11 in the above scheme can detect the humidity at different positions in the room. When it is detected that the humidity at a certain position in the room exceeds the set value, the central control unit 3 can control the dehumidification device 2, adjust to the position, and control the dehumidification power of the dehumidification device 2 based on the humidity difference, so as to achieve scientific control and accurate dehumidification, and prevent the consumption of electric power resources caused by long-time high-power use of the dehumidification device 2.
