Abstract

The invention provides a pulse delay time control method and device. The control method comprises the following steps: acquiring delay time between an input pulse signal and an output pulse signal ofa transmitting module; converting the delay time into a corresponding voltage difference; calculating a voltage error between the voltage difference and a preset voltage difference; the time for outputting the pulse signal of the transmitting module is adjusted according to the voltage error, so that the output pulse is accurately controlled, the time difference of the edges of the input pulse andthe output pulse is not interfered by external factors such as voltage and temperature, and a large amount of test and hardware expenditure costs are saved.

Description

technical field [0001] The invention relates to the field of measurement technology, in particular to a pulse delay time control method and device. Background technique [0002] Most of the existing high-precision ranging solutions are by actively hitting the pulsed light waveform on the obstacle and receiving the reflected beam, and by comparing information such as time difference or phase difference between the emitted light and the reflected light, the distance is obtained by conversion. information. In recent years, there has been an increasing demand for high-precision ranging in short and medium distances. Therefore, the output power required by the light emitter is getting higher and higher, and the application environment is becoming more and more harsh. The anti-interference ability of the light emitter becomes a very important issue. Between the initial input pulse signal of the light emitter and the actual output pulse signal, due to the existence of the data l...
