High-low crane automatic electrical control system and control method

Abstract

The invention provides a high-low crane automatic electrical control system and control method, and belongs to the technical field of electrical control. The high-low crane automatic electrical control system comprises 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 a box girder in hoisting according to an inclination angle sensor in the sensor unit, obtains the RTK space coordinate position of the head end and the tail end of the box girder according to a winch height encoder and a crown block stroke encoder, checks and resets the RTK position of a crown block in operation through an RFID position reader, calculates the RTK space coordinate position of the box girder and compares the RTK space coordinate position with a target value, the box girder is controlled to be lifted according to the difference value, automatic box girder lifting is achieved, the control precision is higher, the labor cost is reduced, and meanwhile the construction efficiency is improved; and the safety protection unit is used for guaranteeing that a certain safety distance is kept between the beam endand other objects, collision and scratching are prevented, the controller unit can control equipment to stop in time when an alarm is given, and construction safety is guaranteed.

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
