Traditional wireless communication technologies is often very power-hungry,and take up too much of the computing and communications resources, increase thecost, which prompted the rapid development of low-cost, low-power,high-performance wireless sensor networks. Wireless sensor network is embeddedinformation processing technology, microelectronic technology, sensor technology,modern networking and wireless communications technologies, and many otheradvanced technology together, and ad-hoc networking abilities to achieve wirelesssensor network components, to study surrounded by a variety of environmentalinformation in real-time monitoring and treatment, a very broad application prospects.The main subject of the application of ZigBee wireless communicationtechnology is to achieve real-time monitoring of the environment of the hotel rooms,and the intelligent control of the electrical equipment room through the ARM9microcontroller. Topics studied in the ZigBee specification and analysis of itsprotocol stack, the system network topology chosen star network structures, wirelesstransmission based on the CC2530communication software design, test resultsobtained after the commissioning of equipment, and complete control of the switch,but also according to the setting of the data has reached the real-time monitoring ofthe room environment.Finally, the basic requirements for wireless sensor network node design,development of a wireless sensor network control system based on ARM9microcontroller as the master node, the hardware circuit chosen the ARM926EJ to thekernel control chip S3C2416as the master node, and wireless chip CC2530via SPIinterface connected to achieve communication and connection hardware systemthrough the I/O port and485to achieve control of the electrical equipment in theguest room.
