The host computer master control chip processes the humiture information firstly and then sends a regulation and control command to the slave computer master control chip to control an executing mechanism for realizing the humiture adjustment. Due to the adoption of the above structure, the complex degree of the wiring operation of the system is reduced and the design cost is lowered by means of a master-slave distributed type structure. Meanwhile, the signal interference is relieved and the maintenance is convenient. The slave computer of the system is small in size, thus being placed in various environments. Moreover, the number of slave computers can be conveniently increased or decreased. In addition, the anti-interference capacity of the system is improved and the reliability of the system is high.
