Abstract

The invention discloses an error detection device of an electronic reading system of a digital level and a detection method thereof. The detection device comprises a lifting table, a leveling rod and a telescope system; the leveling rod is vertically fixed on a moving planker of the lifting table, and the telescope is arranged in front of the digital level to be detected; an object lens of the telescope is opposite to an object lens of the detected digital level, and an ocular lens of the telescope is opposite to the leveling rod. During detection, the detected digital level observes the leveling rod through the telescope to record read data of the digital level when the leveling rod is arranged at different positions, and determines an error of the electronic reading system of the digital level according to a standard deviation formula. In term of the scheme, a detection device with simple structure, compact space and lower price, and a simple, convenient and rapid detection method are adopted on the premise of factually reflecting precision level and reliability level of instruments.

Description

technical field

[0001] The invention relates to a detection device and a detection method of a digital level, in particular to a detection device and a detection method of an electronic reading system error of a digital level. Background technique

[0002] A level is used to measure the difference in height between two points on the ground. The digital level is a kind of level. The digital level is to add an electronic reading system to the traditional optical automatic leveling level to realize automatic scale reading. Therefore, the digital level must not only meet all the technical indicators of the optical automatic leveling instrument, but must also meet the technical indicators of the electronic reading system. At present, only Bowflex's digital level products have entered the mass production stage in China, and only a few foreign manufacturers can produce digital levels. Regarding the detection method of the digital level, the same part as the traditional optical au...
