Problems solved by technology
[0005] Due to the high price of the height measuring device, especially the commonly used laser rangefinder, and the harsh working conditions, limited service life and reliability, and easy interference of data communication, the above-mentioned method measures the height of the container in real time. The method is not widely accepted in practical applications, and there are concerns that if the range finder cannot guarantee the height of the container safely and reliably, the system will instead have fatal errors and accidents

Embodiment Construction
[0040] In order to understand the technical content of the present invention more clearly, the following examples are given in detail.
[0041] Please refer to Figure 1, the safe operation control method of the container hoisting and hoisting system, the system includes a trolley position detection module and a lifting position detection module, including the following steps:
[0042] (1) The system performs initialization operation;
[0043] (2) The system obtains the current position information of the spreader through the trolley position detection module and the lifting position detection module in real time; wherein, the trolley position detection module can be a trolley position absolute encoder, and the lifting position detection module can be Lifting position absolute encoder, the system obtains the current position information of the spreader through the trolley position detection module and the lifting position detection module, which may include the following steps:...

The invention relates to a high-speed and energy-saving safe operation control method for a container hoisting system, comprising the following steps: the system gets the current sling location information in real time through a wheelbarrow position determining module and a lifting position determining module and determines whether the current sling position is in the safe operation area. If so, the system allows the sling to operate at any time; if not, the sling only allows deceleration or slow operation and the system uninterruptedly performs safe operation area self study treatment and repeats the process. The container hoisting system high-speed and energy saving safe operation control method does not need the real-time height measuring unit such as laser, ultrasonic wave distance meter and other units. Being economical and practical, safe and reliable and with simple structure, low cost and a wide application, the system can effectively solve the safety problem caused by collision in container hoisting high-speed operation and is conducive to lowering energy consumption, reducing pollution and labor intensity.
Description
technical field [0001] The invention relates to the technical field of container loading and unloading, in particular to the technical field of operation control during container hoisting, and specifically refers to a method for controlling safe operation of a container hoisting and hoisting system. Background technique [0002] In modern society, the rapid development of logistics makes container hoisting more and more efficient, and the containers in the container yard are stacked at random and uneven. If there is a slight carelessness in the middle of hoisting, the container will be knocked over, and the so-called "bowling" phenomenon will occur, which may lead to serious safety accidents. For the sake of safety, the crane often requires the driver to lift the spreader vertically to the highest point during the hoisting process, which is higher than all possible container heights in the yard, that is, the absolute safe operating height profile of the spreader in the conta...
