This paper introduces the design of a distributed wireless tree-like data acquisition system based on ZigBee, including its composition and the topological structure of ZigBee network. An industrial information transmission system based on ZigBee technology with CC2530 chip is designed. In this paper, every part of the hardware connections and software design will be introduced overall framework of the system. In consideration of the large data transmission and the security of wireless communication, a communication protocol of wireless transmission will be presented. The experimental tests, aiming at those following factors: distance, magnetic field, occlusion, temperature, short interval test and long-time test, have proved that the system has high speed of transmission and safety of information transmission.
