The invention discloses field geographic information surveying and mapping equipment. The equipment comprises a supporting platform, a main shaft and a surveying and mapping instrument adjusting mechanism; the main shaft is hinged to the bottom of the supporting platform; the surveying and mapping instrument adjusting mechanism is fixedly arranged at the top of the supporting platform; the surveying and mapping instrument adjusting mechanism comprises a fixed shaft, a height adjusting mechanism, a direction adjusting mechanism and a pitching adjusting mechanism; the height adjusting mechanismis used for adjusting the height of a surveying and mapping instrument; the direction adjusting mechanism is used for adjusting the surveying and mapping direction of the surveying and mapping instrument; the pitching adjusting mechanism is used for adjusting the surveying and mapping angle of the surveying and mapping instrument; the fixed shaft is fixedly arranged on the direction adjusting mechanism; the height adjusting mechanism is arranged on the direction adjusting mechanism; the pitching adjusting mechanism is arranged on the height adjusting mechanism; and the surveying and mapping instrument is arranged on the pitching adjusting mechanism. The equipment has the beneficial effects that the supporting platform can be rapidly and efficiently leveled, the surveying and mapping direction of the surveying and mapping instrument can be adjusted at will, the height of the surveying and mapping instrument can be adjusted conveniently, the pitching angle of the surveying and mapping instrument can be adjusted and the equipment can adapt to uneven ground.

The invention discloses a platform level automatic adjustment device and an adjustment method, comprising a platform, an air spring is installed under each corner of the platform, the air spring is connected to the upper end of the lifting mechanism installed in the supporting leg, and the lower end of the lifting mechanism is connected to the transmission The device is connected, the base is set under the supporting legs, the support A is installed in the middle of the bottom of the table, and the regulating air valve is fixedly installed under the table. The regulating air valve is connected to the air spring through the air pipe, and one end of the swing rod is the ball head A , fixed by the ferrule on the outer cover of the support A, the other end of the swing rod is equipped with a plumb weight, the rod body of the swing rod is equipped with a cantilever, the end of the cantilever is correspondingly below the contact point of the regulating air valve, and the lock is fixed above the base The plate and the movable magnetic block in the plumb weight are controlled and locked by the remote control switch. The invention also provides a level adjustment method of the platform. The platform adjustment device and the adjustment method have the characteristics of short leveling time, high leveling precision and high reliability.

The present invention provides a leveling device and a reaction chamber, comprising elastic connectors, at least three leveling screws and a leveling plate for carrying support columns, wherein the leveling plate is elastically connected to the bottom wall of the chamber through the elastic connectors; At least three threaded holes penetrating through the thickness of the leveling plate are arranged at intervals along the circumference of the leveling plate; each leveling screw is matched with each threaded hole one by one, and the lower end of each leveling screw against the bottom wall of the chamber. The leveling device and the reaction chamber provided by the present invention can conveniently and quickly level a plurality of support columns, reduce leveling time, and improve work efficiency.

The invention discloses a coordinate measurement system for track lines. The coordinate measurement system comprises a total station, a track inspection car and a processing unit. The total station erected on a track line is used for measuring three-dimensional coordinates of CP III points. The track inspection car running on the rack line is used for measuring line shapes between two corresponding line marking points of the two CP III points on the track line, and measuring horizontal distance and height difference values between the two line marking points and the two corresponding CP III points. According to the three dimensional coordinates of the two CP III points, geometrical relationships between the horizontal distance and height difference values between the two CP III points andthe corresponding line marking points thereof on the track line, and the line shapes between the corresponding line marking points of the CP III points on the track line, the processing unit solves three-dimensional coordinates of the corresponding line marking points of the CP III points on the track line by importing measurement data of the total station and the track inspection car. By the coordinate measurement system, the technical problems of labor and time consumption and low measurement accuracy of existing track line coordinate measurement methods can be solved.
