The invention discloses a universal real-time multi-channel parallel timing measuring
system. The universal real-time multi-channel parallel timing measuring
system comprises an ARMSTM32 series processor, a multi-disc TDC-GPX
chip, a start /
stop signal input interface array, a digital /
simulation diverter switch array, a multi-channel AGC amplifying circuit, a multi-channel high-speed comparison circuit, a touch LCD, an external memory, a temperature sensor and an upper computer. According to the universal real-time multi-channel parallel timing measuring
system, multi-channel simultaneous parallel timing is achieved, and the real-time performance is good;
simulation, digital, single-ended and difference multiple types of
signal input can be supported at the same time, and the applied range is wide; wire length compensation, channel consistency correction and temperature compensation of the multi-disc TDC-GPX
chip and high precision are achieved; one
microprocessor can control 1-4 TDC-GPX chips to form a basic measuring unit, multiple channels are needed, a plurality of basic measuring units are stacked for use, the structure is compact, and the expansibility is strong; by the aid of upper
computer software based on a LabView, the development difficulty of graphical monitoring and displaying application programs is made to be simple.
