Among them lower place machine is mainly made up of several parts ,for example ,frontend sensor, signal regulate circuit, ADC frequency field circuit, FPGA processing modules and the Bluetooth module. The mainly function are pleting frontend data collection , conversion and processing and transfer the data after processed to is mainly made up of USB Bluetooth adapter and PC pleting data display ,monitoring ,storage and other functions. PC send mands to lower place machine. This system mainly realize high precision, high velocity field data realtime data acquisition, USES Bluetooth wireless transmission characteristics of the wireless transmission of data realization. FPGA is the center of this system and through sending mands to control frontend regulate module collecting data. At the same time the collected data by FPGA processing will be transferred to PC with Bluetooth module. The PC will plete the corresponding processing work.
