Embodiment Construction
[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0032] In order to solve the defects of the traditional single-chip embedded technology solution, the present invention designs an FPGA-based tuber resistance imaging data acquisition system to realize high-speed real-time measurement of 6×104 output voltage data of 6×16 array electrodes in the TERT system . Mainly through the FPGA chip to control the hardware circuit and chip, the excitation and signal acquisition of the 6-layer planar array electrodes in the TERT system are swept and controlled, so as to realize the acquisition of the TERT system data.
[0033] Such as figure 1 As shown, the FPGA-based tuber resistance imaging data acquisition system of the present invention specifically includes:
[0034] The signal excitation part includes the FPGA chip, the excitation constant current source and the excitation channel selection unit. The signal excitat...
