Automatic centering and measuring total station

The invention provides an automatic centering and measuring total station. According to the automatic centering and measuring total station, a data signal is collected and processed by a central processing unit; a servo motor A is started to control the expansion and the retraction of three electric telescopic links, so that the total station is moved right above an inductor; the total station is regulated to a centering horizontal position through the synergistic adjustment with a dual-axis inclinometer; the total station automatically measures the height of a measuring instrument through a laser device. According to the automatic centering and measuring total station, the central processing unit automatically calculates an angle needed for rotation and a lofting distance by inputting coordinates of a measuring site, a back-sight point and a to-be-lofted point; a servo motor B is started to control a rotating shaft to rotate the total station to a designated angle. The automatic centering and measuring total station is moved to be near the to-be-lofted point according to an instruction of a distance measuring system; a prism built-in chip which receives a signal of the total station starts a servo motor C to control the electric telescopic links to adjust a prism to be horizontal; a servo motor D is started to control a fine tuning shaft to enable the prism to be moved to the position of the to-be-lofted point.
