Abstract

A high-precision time measurement and control system used in the field of distance measurement belongs to the technical field of time precision measurement. The invention aims to solve the problems of bulky volume and poor measurement versatility of existing high-precision time interval measuring equipment. Its code disc pulse measurement module is used to sample the number of pulses of the grating encoder; the motor control module is used to adjust the angular position of the motor according to the number of pulses sampled by the code disc pulse measurement module, and then adjust the emission angle of the laser transmitter; the timing generation module Under the control of the logic control module, it is used to generate a delay pulse that triggers the laser receiver to be turned on; the time interval measurement module is used to measure the time from the detection of the external trigger signal of the laser transmitter to the start of the laser receiver under the control of the logic control module. Time interval; the GPS timing module is used to add time labels to each group of corresponding measurement data by using satellite timing under the control of the logic control module. The invention is used for high-precision time measurement and control.

Description

technical field [0001] The invention relates to a high-precision time measurement and control system used in the field of ranging, and belongs to the technical field of time precision measurement. Background technique [0002] Time interval measurement technology is widely used in modern scientific research and engineering practice, and its development process has always been related to national economic construction and national defense construction, especially in the military field. Therefore, countries around the world began to vigorously develop this technology very early. The annual meeting of PTTI (Precise Time and Time Interval) in the United States held a special discussion on time interval measurement technology every year. The National Academy of Sciences of the United States has listed this technology as a country that must vigorously develop. One of science and technology. This technology plays an essential and important role in many fields such as basic physics...
