It focuses on its external system configuration, including frequency fan fuzzy controller design and RF module program base on CC2540, and describes the hardware design and software drivers on STM32 and the construction on WIFI network communications structure. The indoor temperature can be monitored and regulated in wireless by wireless temperature acquisition system and VAV system controller. The thermostat internal system, integrated with two Fuzzy adaptive control algorithms of frequency fan, is identified and set for related parameters by the user. The accurate adjustment between the host computer and the thermostat is acheived by WIFI protocol, and the communication is set to make the control system more intelligent.
