Automatic leveling platform and leveling method

Abstract

The invention belongs to the technical field of photoelectric measurement. The platform comprises supporting legs, an inclination measuring sensor, an electric rotating table, an encoder and a platform, the supporting legs are fixed to the two opposite sides of the platform and used for leveling the platform, the inclination measuring sensor and the encoder are arranged on the electric rotating table in the center of the platform and is used for acquiring inclination information of the platform; the encoder is located on a rotating shaft of the electric rotating table and provides rotating angle information for the electric rotating table. The automatic leveling platform has the automatic leveling capacity, a manual fine leveling mechanism of traditional optical measurement equipment can be omitted, the leveling precision needed by equipment work is achieved, manual operation steps and time are reduced, and the rapid maneuvering layout capacity of the equipment is improved.

Description

technical field [0001] The invention belongs to the technical field of photoelectric measurement, and in particular relates to a high-precision automatic leveling platform and a leveling method. Background technique [0002] When the vehicle-mounted optical measurement equipment performs measurement work, there are usually two working modes: floor measurement and non-floor measurement. Since the non-ground measurement has short deployment and withdrawal time, simple operation, and can get rid of the location constraints of the measurement site, and has the ability to quickly maneuver and transition, it has gradually become the main working method of optical measurement equipment. Chinese patents CN108482263A and CN110588483A announced the non-floor measurement scheme of the high-rigidity platform carrying optical measurement equipment, which can effectively isolate external interference such as vehicle loading, and has an automatic leveling function, providing a better solut...

Problems solved by technology

Chinese patents CN108482263A and CN110588483A announced the non-floor measurement scheme of the high-rigidity platform carrying optical measurement equipment, which can effectively isolate external interference such as vehicle loading, and has an automatic leveling function, providing a better solution for the non-ground measurement of vehicle-mounted optical measurement equipment Solution, but the leveling accuracy of the current leveling platform is generally 30″~120″, it is difficult to achieve the leveling accuracy required by the optical measurement equipment, so it is necessary to use the manual leveling mechanism of the optical measurement equipment itself to fine-level to 2″ ~5″, time-consuming and labor-intensive
