Background

An invar bar code leveling staff (hereinafter referred to as a bar code ruler) is a tool for leveling and is matched with an electronic level for use. In the measurement, the bar code ruler must be kept vertical, so that two circular bubbles are respectively arranged above and below the bar code ruler, and the verticality of the bar code ruler is ensured. Along with the development of science and technology, the electronic level has gradually replaced ordinary level and has entered into the construction unit, and the bar code chi is the indispensable instrument of electronic level leveling, therefore the bar code chi is used for leveling more and more, because the bar code chi uses frequently, the round bubble on the bar code chi that makes often becomes flexible the skew, leads to the elevation of measuring to have the mistake to influence measurement accuracy. The currently commonly used calibration method is an instrumental calibration method: firstly, a bar code ruler is erected on the ground by means of a ruler support, two total stations (or theodolites) are erected on the ground, the two instruments and the bar code ruler are approximately at an angle of 90 ℃, the instruments are about 20 meters away from the bar code ruler, the total stations are leveled, so that the vertical wires of the two total stations and two edges of the bar code ruler are superposed, if the vertical wires and the two edges of the bar code ruler are not superposed, the bar code ruler is moved to be superposed, at the moment, if the bar code ruler is vertical, two air bubbles are centered, if the bar code ruler is not vertical, the air bubbles are deviated, and if the bar code ruler is deviated, circular air bubbles are adjusted. The method needs to be corrected outdoors, the bar code ruler is not firmly placed on the ground, the bar code ruler can move when the force is large during air bubble adjustment, the precision is affected, and meanwhile, other personnel are needed to cooperate, so that time and labor are wasted.
