Background

In the field of precision engineering measurement or deformation monitoring such as large-scale building on the ground and underground tunnel construction, a total station is often used for carrying out specific measurement operation. The total station is a surveying instrument system integrating the functions of measuring horizontal angle, vertical angle, distance and height difference, so that the total measurement work on the measuring station can be completed by arranging an instrument once. When using the total station to measure, the total station is usually firmly supported by using the tripod as a measurement auxiliary device for preliminary station establishment.

The tripod comprises a supporting disc and three supporting legs hinged to the supporting disc, through holes for fixing the total station are formed in the supporting disc, and tip parts are arranged at the tail ends of the three supporting legs. When the preliminary station building of the total station is carried out, three supporting legs are opened to be erected on the ground, the total station is placed on the supporting disc, a threaded rod below the total station penetrates through the through hole to be fixed through the nut, the infrared laser point at the bottom of the total station is opened, the infrared laser point of the total station coincides with the center of the centering mark point drawn on the ground in advance, and the preliminary station building of the total station can be completed by leveling the three supporting legs. During measurement, two other observation points are selected, a prism is placed at the observation points, and then the total station sighting prism is used for measuring operation.

For the related art, when performing measurement work, a group of three persons is often required, two persons stand at the prism respectively, and one person performs measurement at the total station. Because of the extremely high precision typically required for measurement operations, a self-test is required after a single measurement, preferably by an exchange person before aiming the other two prisms. When the total station is alternatively measured, the height of the triangular bracket needs to be adjusted to a proper observation height according to the height of a measurer, the method for adjusting the height of the triangular bracket is to open or close three supporting legs of the triangular bracket, then the total station is re-aligned and leveled, and the alignment and leveling are needed to be re-performed each time when the measurer is replaced, so that the time consumption is long and the operation efficiency is low.
