Problems solved by technology
However, in the current large-scale gantry cranes, the design of slew and amplitude is mainly: installing an angle sensor or a limiter at the joint between the tower arm and the tower base of the gantry crane, which is based on the angle deflection measurement of the mechanical method. Problems that are complex and require high precision, and are greatly affected by mechanic

Embodiment Construction
[0036] The present invention is described in detail below in conjunction with the accompanying drawings:
[0037] like figure 1 As shown, the GPS-based gantry crane attitude monitoring system provided by the present invention includes: a processor, a motion control system, a GPS receiving board, and at least one set of GPS antenna groups; On each support arm of the gantry crane boom system, the signal output end of each GPS antenna is connected with the signal input end of the GPS receiving board; the signal output end of the GPS receiving board is connected with the signal input end of the processor The signal output end of the processor is connected with the signal input end of the motion control system. It can also include a power supply; the power supply is respectively connected with the processor and the GPS receiving board.
[0038] Among them, in order to ensure that each GPS antenna can receive satellite signals, the GPS antenna needs to be fixedly installed on the ...

The invention provides a GPS-based gantry crane attitude monitoring system and a method thereof. The attitude monitoring system comprises a processor, a motion controlling system, a GPS receiving board, and at least one GPS antenna set; the GPS antenna sets are fixed respectively on each branched arm of a boom system of the gantry crane; signal output terminal of each GPS antenna set is connected with a signal input terminal of the GPS receiving board; a signal output terminal of the GPS receiving board is connected with a signal input terminal of the processor; and a signal output terminal of the processor is connected with a signal input terminal of the motion controlling system. Detection of turning attitude of the gantry crane boom system is based on GPS, and is independent from the moving parts and a controlling system, so that the attitude monitoring system will not be influenced by factors such as machinery part wear and ageing, and has a long service life. In addition, the system has no accumulated error, and has high measuring accuracy.
Description
technical field [0001] The invention belongs to the technical field of portal crane control, and in particular relates to a GPS-based attitude monitoring system and method of a portal crane. Background technique [0002] Portal cranes are important equipment for port loading and unloading operations and ship construction. They are mainly used for hoisting tasks of components and goods. Due to their good performance, portal cranes are widely used in shipyards and ports. [0003] With the rapid development of world shipping and the improvement of ship construction efficiency, the gantry cranes arranged in shipyards and ports are becoming more and more dense, the collision between gantry cranes, and the frequency of collision between gantry cranes and surrounding buildings It has also increased, and major accidents have occurred from time to time. [0004] In order to solve the above-mentioned collision problem, in the prior art, a design of real-time monitoring of the slewing...
