Container wharf RTG and RMG lower container truck alignment guide system and method

Abstract

The invention discloses a container wharf RTG and RMG lower container truck alignment guide system and method. A laser scanning rangefinder, an LED display screen, a loudspeaker, a high-speed embedded controller and other components are adopted, and automatic precise guide of alignment of an RTG / RMG lower container truck is achieved. The high-speed embedded controller carries out conversion, calculation and contour recognition on measured data obtained through two-dimensional scanning on a container truck frame or a container on the frame through the laser scanning rangefinder in the direction parallel to the central line of a container lane, the position of the container truck and the deviation distance between the container truck and the benchmark hoisting point of a gantry crane are accordingly judged, meanwhile, the hoisting direction and distance information of the container truck deviating the hoisting point are displayed on the LED display screen, and a driver of the container truck is prompted to adjust the parking position of the container truck in advance.

Description

technical field [0001] The invention relates to the technical field of container loading and unloading, in particular to a system and method for alignment and guidance of RTG and RMG down-collectors at container terminals. Background technique [0002] In recent years, with the rapid development of the international logistics industry, the throughput of container ports in various countries has continued to increase, and the operations in container yards have become increasingly busy. High-efficiency ports are inseparable from high-efficiency mechanical equipment and high-tech applications. RTG / RMG (tyre / rail-mounted container gantry cranes) are important operating tools for container terminals, and their operating efficiency directly affects the overall operating efficiency of the terminal. . The traditional method is mainly to increase the operating speed of the RTG / RMG's cart, trolley and lifting mechanism to achieve the fastest operating efficiency. However, with the de...

Problems solved by technology

However, in actual use, it was found that: since the laser scanning rangefinder also takes into account the function of preventing the collection card from being lifted, the installation position is unreasonable, and the position of the collection card cannot be effectively detected; The deviation of the coordinate position leads to a large positioning deviation of the collection truck; and the system uses wireless communication to send the alignment information to the alignment information box in the driver's cab of the collection truck, the system is easily disturbed, and the stability is difficult to meet the requirements of continuous operation on site

Moreover, the system cannot fully identify the actual operating conditions of the trucks, and misjudgment of the operating conditions occurs during the operation of empty trucks and the operation of multiple 20-foot containers, making the system unable to reach the level of practical application
