Design of Wireless Data Acquisition System in Nuclear Physics Experiment Based on ZigBee

摘要

In Inertial Confinement Fusion experiment (ICF), the intense radiation environment required the experimenter to stay away from the experimental site. The detector signal has to be transmitted to a safe area through long signal cable, which will not only aggravate signal transmission attenuation, reduce SNR, affect the measurement precision, but also bring in a high cost of the experiment system. Therefore, we designed a data acquisition system based on ZigBee wireless communication technology. ZigBee has its advantages of low power consumption, about 30 mA working current and 1 uA dormant current, convenient arrangement and flexible networking. The wireless communication distance can reach up to 50 m and the wireless communication rate can reach about 11.5 kbps. Based on CC2530 wireless network chip, the system can achieve the wireless data acquisition and remote control.
