Embodiment 1

[0040] In Fig. 1, the layout diagram of the position positioning of the crane is given. It can be seen from Figure 1 that the crane is composed of a cart, main and auxiliary trolleys, and main and auxiliary hooks. If the crane wants to lift a heavy object, it should first drive the cart to run directly above the position of the heavy object. Adjust the position of the main and auxiliary trolleys so that the hook is directly above the heavy object, and finally adjust the height of the main hook to lift the heavy object. From this process, the coordinates of the positioning of the crane can be obtained, that is, the running direction of the large crane is x, the running direction of the main trolley and auxiliary trolley of the crane is y, and the running direction of the main and auxiliary hooks is set to z. Through this coordinate, the location of the transferred goods can be precisely located.

[0041] Figure 2 shows the coordinate system setting position map of the crane po...

Abstract

The invention relates to an overhead traveling crane positioning system and a positioning method, which adopts an industrial control computer as the core, organically integrates the industrial control computer, data collection cards, a lower computer PLC and a sensor and fully displays the advantages of all the parts. Without changing the design and the control scheme of the original overhead traveling crane, the invention adopts a high-precision laser sensor and an encoder to measure and obtain the distances in the x, y and z directions of the overhead traveling crane, sends the distances into the CPU of the industrial control computer by different types of data collection cards, meanwhile, adopts the OPC technology to read the running status of the overhead traveling crane from the lower computer PLC to an upper computer: the industrial control computer through a CAN-bus, and then composes the data processing and interface display programs in Visual Basic and other high-level languages in the industrial control computer, to real time display the running position and status of the overhead traveling crane, so as to provide precise running data of the overhead traveling crane for the operator and lay a solid research foundation for the overhead traveling crane to be driven without a driver with high precision.

Description

technical field [0001] The invention relates to a high-precision crane positioning system and positioning method. Background technique [0002] There are two traditional ways to locate the crane. One is to draw colored bars of different colors on a wall in the direction of the crane’s running. Each color represents a certain distance. The driver of the crane should check the colored bars on the wall at any time. , and then to judge the position of the crane, the distance between every two color bars is at least 20cm, so that the positioning of the crane is inaccurate, and at the same time, the operator of the crane is required to have a good memory and Only by experience can we know the approximate location of the crane. At the same time, there must be a person under the car to direct, so that the crane can reach the predetermined position, and the efficiency is extremely low. This method has relatively high requirements for the crane operator, who must be a very experienc...
