Embodiment 1

[0041] The technical problem mainly solved by the present invention is to provide a grab swing amplitude GPS positioning system, the system is composed of grab mechanism installation bracket protective cover, inertial navigation GPS equipment and antenna, DTU communication module, power supply battery, ground GPS differential base station, pendulum Width detection system composition.

[0042] According to the complex working conditions of the ship unloader, a dust-proof and vibration-proof mounting bracket protective cover is designed to accommodate the inertial navigation GPS equipment, DTU communication module, and power supply battery. It is necessary to keep the GPS antenna and DTU antenna upright and firm, and select the best installation position to reduce the impact from the top block. The ground computer links the DTU equipment, and the data collection is completed through the point-to-point communication between the two DTUs. The ground computer swing detection syste...

Embodiment 2

[0077] The grab mechanism swing GPS positioning system provided according to the present invention includes:

[0078] The inertial navigation GPS equipment uses INS-D, and its working parameters are: working temperature -40℃~+70℃, power supply voltage 9V~36VDC, power consumption 2.6W, communication interface RS-232, RS-422, RS-485. The size is 120mm×50mm×53mm, and the weight is 320g. Use DTU equipment to connect to the ground base station to receive differential signals for differential processing. One end of the DTU communication module is connected to the INS-D and the GPS body, and the other end is connected to the ground base station and industrial computer to process the returned information on the grab platform, and point-to-point communication between the two DTU communication modules.

[0079] Due to the difficulty of power supply on the grab platform, after research and design, the power supply of the equipment on the grab platform is powered by a battery. The batter...

Abstract

The invention provides a grab bucket mechanism swing GPS positioning system and method and a medium. The grab bucket mechanism swing GPS positioning system comprises a grab bucket mechanism, a protective cover, inertial navigation GPS equipment, DTU communication modules, a power supply battery, a ground GPS differential base station, a ground computer and a swing detection system, wherein the grab bucket mechanism, the inertial navigation GPS equipment, the DTU communication module and the power supply storage battery are connected with one another and are mounted in the protective cover; the ground computer is connected with one DTU communication module, a mobile station on the grab bucket mechanism is connected with one DTU communication module, and GPS positioning data collection is completed through point-to-point communication of the two DTU communication modules; the DTU communication module is linked with the ground GPS differential base station; the swing detection system is connected with the DTU communication modules. According to the grab bucket mechanism swing GPS positioning system, accurate grab bucket positioning and swing detection in the automatic ship unloading process of a ship unloader are achieved, a control closed loop is effectively formed, and the situation that a grab bucket impacts a cabin in the automatic ship unloading process is prevented.

Description

technical field [0001] The invention relates to the technical field of industrial control, in particular to a grab mechanism swing GPS positioning system, method and medium. Background technique [0002] The operation mode of existing ship unloader has two kinds: manual mode and semi-automatic mode. The efficiency of the manual unloading method depends entirely on the proficiency of the driver, which is likely to cause the swing of the grab bucket, which is greatly affected by human factors, and the operating efficiency is unstable. The semi-automatic operation method has two disadvantages: on the one hand, the driver needs to manually set and update the operation parameters continuously, the operation adaptability is not strong, and there are greater safety risks. [0003] Therefore, bridge grab ship unloaders at home and abroad are beginning to develop towards unmanned automation. [0004] On the 12U1 and 12U2 bridge ship unloaders at Baosteel’s raw material wharf, the e...
