Design of node controller for wireless monitoring system of central air conditioner

Central air conditioning is one of the very important and common equipment in intelligent building. In order to make the air conditioning system operate in an efficient and energy-saving state, the central air conditioning intelligent control system has studied based on wireless sensor network (WSN). The node controller is the core component of the central air conditioning control system. It realizes the control of the terminal equipment and the collection of the signals, and the wireless communication with the routing nodes. In this paper, the hardware circuit and software design of the note controller is proposed, and produces a prototype. The wireless real-time monitoring and control of the air conditioning system is realized, and the experimental results on the prototype show that the system runs stably.
