Abstract
ZigBee wireless communication technology makes use of wireless mode to communicate data, which makes data transmission not restricted by industrial environment factors, and has the advantages of reliable and stable transmission. On the basis of reading the relevant literature at home and abroad in batches, the data of ZigBee wireless transmission control loop structure havingbeen sorted out, a wireless data acquisition system with a temperature and humidity sensor node, a three-axis acceleration sensor node and a coordinator node is made. The acquisition frequency is adjusted., and finally, the acquisition frequency is received at 100Hz and 1000Hz. The loss rate and error rate of collected data are analyzed. The main contents include:
(1)The paper takes the high-frequency data acquisition system based on ZigBee wireless transmission as the research object, comprehensively considers the temperature and humidity data and the acquisition method and transmission process of the three-axis acceleration data, and determines the composition and structure of the wireless sensor network system.
(2) Through the understanding of the principle and method of using temperature and humidity sensor and three-axis acceleration sensor, it is determined that the temperature and humidity sensor DHT11 and three-axis acceleration sensor MPU-6500 are used to collect the corresponding data.
(3) Through the understanding of the working principle and use method of ZigBee hardware CC2530 and the basic method of programming and debugging of ZigBee software IAR, CC2530 is used as the controller and IAR as the programming tool to program the control time sequence of DHT11. The I2C communication data transmission mode of MPU-6500 is adopted. The register function of MPU-6500 is programmed. The temperature and humidity and triaxial acceleration data are collected; [资料来源：Doc163.com]
(4) By setting up the network, the wireless network transmission between two terminals and a coordinator is realized, and through the data processing function of the coordinator, the fan's feedback to the temperature data is realized.
