Study And Design Of Wireless Sensor Network Node Based On CC430

With the continuous development of sensor technology and wireless networktechnology, these technologies are more and more mature and extensive. More and morewireless sensor network nodes are placed in our life. People can perceive and monitorchanging of the environment around us by them. Wireless sensor network has manyadvantages: perceiving the information, communicating through wireless data, executingaction and so on. So it is very suitable for the intelligent home.Firstly, this paper studies the characteristics of wireless sensor networks, the needingof intelligent home and analyzing the feasibility.Simultaneously, it designs the overallsolution which includes AM602I motion sensor, temperature sensor, and SimpliciTIprotocol stack.Secondly, design the system hardware node CC430Box.The core is the system onCC430wireless RF chip, its peripheral function modules contain AMI602motion sensor,DS18B20temperature sensor, CPLD module and so on.Thirdly, this paper designs software system on the basis of the hardware system andCompletes the migration of SimpliciTI network protocol on CC430Box, applicationprocedure design about data center node and terminal node. It has the functions of systemnetworking, data acquisition, and appliance control.Finally, this paper tests system on the basis of hardware and software. Then proposeda measurement program about wireless sensor network node power consumption and testthe power consumption of CC430Box node. It Completes data bit error rate, systemnetworking, data acquisition, and appliance control experiments, then analysis theexperimental results. The wireless sensor network nodes have advantages of low powerconsumption, high flexibility and easy to extend, fully meet the system requirements.
