Problems solved by technology

However, the manual observation results will be interfered by many factors such as the driver's experience, emotion, weather, etc., and the accuracy is difficult to guarantee. If the driver is slightly negligent or the measurement accuracy is inaccurate, it is easy to cause shipwreck, capsize, bulkhead (bottom) damage, and storage yard. Accidents such as ground damage; camera-based methods are also limited because the harsh environment of bulk terminals can cause contamination of camera and standard marker images or reduce the reliability of digital video camera vision systems, so for bulk terminal machinery, dry It is impractical for bulk cargo and bulk carriers to install standard marking images

Embodiment Construction

[0020] based on the following Figure 1 ~ Figure 3 , specifically explain the preferred embodiment of the present invention.

[0021] Such as figure 1 As shown, the present invention provides a device for detecting the dumping position and pile height of a quay-wall shifting ship loader, which includes a circuit-connected laser radar array, a radar movement mechanism and an industrial computer 3 .

[0022] The laser radar array includes four two-dimensional laser radars 101, which are respectively installed on the four corners of the square maintenance platform of the barrel of the ship loader.

[0023] The radar movement mechanism is a servo motor 201, and its servo motor driver can directly receive the communication command from the industrial computer to perform position control and drive the laser radar to scan at multiple angles in the horizontal direction.

[0024] The industrial computer 3 is used for background data processing, and has a display, which can monitor th...

Abstract

Provided are a device and method for detecting heights of material piles at material throwing positions of a dock wall moving type ship loader. A laser radar assembly is installed on a ship loader installing platform so as to be used for performing real-time scanning on the material throwing process and a material pile state of the current material throwing positions and then calculating the material pile heights. The device and method for detecting the heights of the material piles at the material throwing positions of the dock wall moving type ship loader are high in accuracy and good in stability, interference of various factors such as driver experience, moods and weather is removed, safety in the automatic blanking process is guaranteed well, and the ship loader can automatically finish bulk cargo shipping operation on the basis of safety in operation.

Description

technical field [0001] The invention relates to a device and a detection method for detecting the height of a material pile at the throwing position of a quay wall shifting ship loader. Background technique [0002] In port bulk cargo handling operations, the distribution, height, volume, etc. of the operating stockpile need to be monitored in real time, and the working parameters of the subsequent operations are determined through certain rules of calculation. For the ship loader, after the cargo is thrown out by the throwing shovel, a conical stockpile is formed in the cabin. In order to avoid the throwing shovel from hitting the stockpile, the driver is currently mainly observing and estimating with the naked eye, or by installing a camera to assist observation. However, the manual observation results will be interfered by many factors such as the driver's experience, emotion, weather, etc., and the accuracy is difficult to be guaranteed. If the driver is slightly neglige...
