If the control network adopts an independent coordinate system, the horizontal orientation of the prism can be correctly adjusted by considering the included angle between the north direction and the magnetic north direction of the independent coordinate system.

(2) And the surveyor A sends the calculation result to the wireless terminal at each corresponding target prism by using the wireless control terminal at the measuring station, and controls the steering engine to rotate so that the target prism faces the intelligent total station.
(3) The observation test has good field of view, and the measurer A can determine the approximate direction of a certain target point, so that the measurer A aims the intelligent total station at the target point for one observation to obtain the observed distance information s= 616.4432m, and the measurer A determines the target point as a control network point TS03 in combination with the forward-phase coordinate information; and then the computer can calculate the spatial relationship such as the vertical angle, the horizontal angle and the like between the other target points and the measuring station. According to the calculated spatial relationship, the intelligent total station can be combined with an automatic target recognition function to develop automatic observation for each target point. During automatic observation, the wireless control end can read weather information corresponding to the multifunctional prism for correcting the distance observation value.
(4) After the observation task at the measuring station TS01 is completed, the measurer A sends a command by utilizing the wireless control end to enable the vertical steering engine directions of the multifunctional prisms at the target points TS02, TS04 and TS03 to be zeroed, and meanwhile, each multifunctional prism enters a low-power-consumption dormant state. Taking down an intelligent total station at a measuring station TS01 by a measurer A, and restoring the previously taken down multifunctional prism to a control station TS 01; carrying the intelligent total station and the wireless control terminal to go to the next control network point for unfolding observation.
(5) And the measurer A sequentially goes to each control site until the observation of all the control sites is completed, and the multifunctional prism is recovered.
