To satisfy the requirement for the multi-source teledata in many different spots synchronization acquisition,processing and transmission,a method of date acquisition and communication based on DSP and net is presented,which utilize the high operation speed of DSP2812 and the merit of net.Its software and hardware realization and function are described,the hardware circuit of the system is greatly simplified,which can achieve high-precision frequency and phase measurement and data acquisition which signal come from many channels,and the frequency and phase measurement can overcome the impact of interference,the frequency of signal acquisition can be changed arbitrarily in accordance with the need.Finally,the data which has been processed is sent to the PC for further processing by network.
