A high and low crane automatic electrical control system and control method

Abstract

The invention provides an automatic electric control system and control method for high and low cranes, belonging to the technical field of electric control, including a controller unit, a display unit, a sensor unit, a wireless transmission unit and a safety protection unit. The controller unit obtains the attitude of the box girder during hoisting according to the inclination sensor in the sensor unit, obtains the RTK spatial coordinate position of the head and tail of the box girder according to the hoist height encoder and the crane stroke encoder, and checks and resets the sky through the RFID position reader. The RTK position of the vehicle during operation, calculate the RTK space coordinate position of the box girder and compare it with the target value, control the lifting of the box girder according to the difference, realize the automatic box girder hoisting, the control accuracy is higher, the labor cost is reduced, and the construction efficiency is improved at the same time ; The safety protection unit is used to ensure a certain safe distance between the beam end and other objects to prevent collisions and scratches. When an alarm occurs, the controller unit can control the equipment to stop in time to ensure construction safety.

Description

technical field [0001] The invention belongs to the technical field of electric control, and in particular relates to an automatic electric control system and control method for high and low cranes. Background technique [0002] With the country's large-scale construction of infrastructure projects, in recent years, the construction of high-speed rail, highways, and municipal projects has developed rapidly. The construction of infrastructure projects has led to the emergence of a number of large-scale construction machinery, and the number of related manufacturing plants is huge. Although the mechanical equipment is constantly being updated, the control system of large-scale construction machinery equipment has always remained at the manual control level. Workers are unskilled in operation or inattentive, leading to major mechanical accidents and even work-related fatal accidents. Especially in the face of more complex operating procedures, it is often necessary to arrange ...

The construction of infrastructure projects has led to the emergence of a number of large-scale construction machinery, and the number of related manufacturing plants is huge. Although the mechanical equipment is constantly being updated, the control system of large-scale construction machinery equipment has always remained at the manual control level. Workers are unskilled in operation or inattentive, leading to major mechanical accidents or even fatal accidents

Especially in the face of more complicated operating procedures, it is often necessary to arrange guardians at key positions to ensure that the mechanism does not perform dangerous operations. In this way, a large number of guardians need to be added, and the labor cost is greatly increased.

Moreover, due to the relatively large observation limitations of the human eye, in addition to its own factors, it is also affected by the external environment, such as being affected by problems such as blurred vision at night, and there are still potential safety hazards
