Embodiment Construction

[0050] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0051] Such as figure 1 As shown, in the attitude measurement of the tower crane, the coordinates of the Beidou / GNSS receiver antenna installed on the tower crane in the carrier coordinate system must be measured first, and then the attitude angle of the Beidou / GNSS receiver antenna is obtained through the double-difference attitude measurement model, and then Monitor the attitude information of the tower crane.

[0052] The carrier coordinate system can be converted to the geographic coordinate system through the latitude and longitude information received by the Beidou / GNSS receiver, and then converted to the carrier coordinate system. The specific method is as follows:

[0053] First, assume that the origin of the geographic coordinate system ...

Abstract

The invention relates to the technical field of tower crane monitoring, in particular to a method for automatically monitoring attitude of a tower crane based on Beidou / GNSS, and the method comprisesthe following steps of receiving a Beidou / GNSS satellite signal through a receiving antenna of a Beidou / GNSS receiver by the Beidou / GNSS monitoring equipment on the tower crane; using the phase centerof the satellite antenna as a carrier center to extract the latitude and longitude coordinates in the satellite signal; converting the latitude and longitude coordinates into vector coordinates by the coordinate transformation principle to establish an attitude matrix; obtaining an attitude angle through a double-difference attitude measurement model, and monitoring the attitude information of the tower crane through the attitude angle. The method for automatically monitoring attitude of the tower crane based on Beidou / GNSS provided by the invention can monitor the heading angle, roll angle,pitch angle and other parameter information of the tower crane, and the monitoring information is comprehensive.

Description

technical field [0001] The invention relates to the technical field of tower crane monitoring, in particular to a method for automatically monitoring tower crane posture based on Beidou / GNSS. Background technique [0002] With the development of large-scale, complex and rapid construction projects in the market, the safety supervision of large-scale equipment on the construction site will be the top priority in the development of safety management of construction projects in the future, and tower cranes are also moving towards automation and multi-function accordingly. , Large-scale route development. In recent years, tower crane accidents have occurred frequently, not only causing serious casualties, but also causing huge economic losses. Although most of the current monitoring methods can monitor the attitude of the tower crane, the monitoring methods generally have factors such as low monitoring accuracy, untimely monitoring, and greater influence by the weather. The pr...
