【Abstract】 In order to improve the distributed data acquisition capability of wireless sensor networks， a high-speed distributed data acquisition system based on integrated DSP is designed. The system consists of sensor information fusion module， clock control module， power supply module， DSP integrated control module and human-computer interaction module.
