Abstract

The present invention provides an angle automatic measurement system, including a laser source, a stepping motor, a drive detector, a photoelectric sensor, and a controller wherein the controller is connected with the laser source, the drive detector and the photoelectric sensor respectively. The invention also provides an automatic measurement method using the system, and the method includes: a laser beam sweeps a first array and a second array in a succession manner; when the second array is swept, the stepping motor stops and the smallest step angle of the stopped stepping motor is recorded; after that, the laser source inversion proceeds in which the laser beam sweeps the second array and the first array in a succession manner; and when the first array is swept, the smallest inverse step angle of the stopped stepping motor is recorded; after that, the time lasting from the inversion starting to when the second array is swept, the time when the first array is swept after the sweeping of the second array and the time from when the first array is swept to when the inversion stops are calculated; and based on the above data, the deviation angle value is calculated. With the system of the invention, it is possible to automatically measure the angle information with high automation. The system can be remotely controlled so that high power microwave radiation does not pose damage to the body of a testing man.

Description

technical field [0001] The invention relates to the technical field of angle measurement, in particular to an automatic angle measurement system and method. Background technique [0002] When the military radar interferometer direction finding antenna performs periodic direction finding calibration, it is necessary to determine the offset angle value between the center point of the interferometer antenna front and the direction vector of the connection line of the remote device and the normal vector of the interferometer antenna front. The traditional method is The total station is used to manually determine the angle. The operation is complex, the degree of automation is low, and it is difficult for soldiers to use it. It cannot be integrated into the interferometer calibration system. The test work takes a long time and does not meet the current high-efficiency combat needs. Microwave radiation will damage the health of test personnel. Contents of the invention [0003]...
