Embodiment

[0031] Such as figure 1 As shown, a distance measuring system provided by the present invention has the characteristics of low cost, simplified circuit and high confidentiality. The traditional TOF distance measuring needs a transmitting circuit, a receiving circuit, a time difference measuring circuit and a digital control circuit, so the system circuit The cost is high, and the debugging is complicated. All the time difference signals of the present invention are completed by the high-speed FPGA of the logic control circuit, and utilize the high-speed FPGA to collect the initial signal of the transmitting circuit circuit, and the LVDS unit collects the differential signal from the receiving end, and the LVDS unit collects the signal from the For the differential signal at the receiving end, the received signal outputs a STOP signal after passing through the LVDS unit, which saves the time difference measurement circuit in the prior art as a whole, saves the cost, and simplifi...
