In order to solve the problems of single channel, large power consumption, poor anti-interference ability and low collection efficiency of the collector designed by traditional methods, a multi sensor multi-channel data parallel high-speed acquisition device is designed. The operation principle of the data collector is analyzed. Firstly, two interfering factors, which affect the high efficiency of the collector's high frequency noise and high frequency carrier, are filtered. Synchronous acquisition of data signals, data validation, through data acquisition and processing, to achieve multi sensor channels, multipoint data parallel, high-speed acquisition design. The experimental results show that the improved data collector has less power consumption, strong anti-interference ability and high collection efficiency.
