Problems solved by technology

[0004] The inventors of the present disclosure have found that the existing work sheds have the following problems: (1) It is inconvenient to move. Although there are movable or detachable work sheds in the prior art, most of them need to be manually pushed and moved, requiring the cooperation of many people and there are Certain danger; (2) The movement error is relatively large. The shed is moved by pushing, and the force of each person is not uniform, which will easily lead to the movement deviation of the shed, which will cause the shed to collide or rub against the track, thus causing the shed to move. Difficult; (3) Manual deviation correction is required. When there is a large deviation in the movement of the shed, manual coordination and correction is required. The automation level is poor, and it is impossible to realize the high-precision and rapid movement of the shed according to the preset track; (4) The environment of the construction site is relatively complicated , there are many people, and the existing work sheds cannot effectively identify and avoid obstacles during the moving process, and safety accidents are prone to occur

Embodiment 1

[0034] Embodiment 1 of the present disclosure provides an intelligent control system for a mobile shed, which is realized by using four motors to drive four road wheels. The three-phase asynchronous motor drives the four wheels through a reducer to move forward and backward along the guide rail.

[0035] The speed of the four wheels is controlled by the frequency converter matched with the motor, and the controller sets the same starting acceleration / deceleration curve, walking speed and synchronous start / stop signal for the frequency converter to realize basic walking control, such as figure 1 This is the schematic diagram of the walking control, and the frequency converter is used to set the same working state for each walking, which ensures the stability of the shed when moving, and also reduces the direction deviation caused by the inconsistent speed on both sides.

Embodiment 2

[0044] Embodiment 2 of the present disclosure provides an intelligent control method for a mobile shed, using the intelligent control system for a mobile shed described in Embodiment 1, specifically including the following aspects:

[0045] (1) The shed moves automatically

[0046] Four motors are used to drive four road wheels. The three-phase asynchronous motor drives the four wheels through the reducer, and moves forward and backward along the guide rail. The speed of the four wheels is controlled by a frequency converter matched with the motor. The controller sets the same starting acceleration / deceleration curve, walking speed and synchronous start / stop signal for the inverter to realize basic walking control;

[0047] Intelligent switching between two-wheel drive and four-wheel drive, installing a load detection sensor on the driving motor to detect the motor load in real time, when the load is less than the set value, the two-wheel drive is enabled, and when the load i...

Embodiment 3

[0059] Embodiment 3 of the present disclosure provides a mobile work shed, including the intelligent control system for the mobile work shed described in Embodiment 1 of the present disclosure.

Abstract

The invention provides an intelligent control system and method of a movable work shed, and belongs to the technical field of integrated control. The intelligent control system comprises the work shedand a controller, wherein the work shed can move along a preset track through walking wheels at the bottom, each walking wheel is driven by an independent motor, and each motor drives the corresponding walking wheel to move according to an instruction of the controller; load detection sensors are arranged on the motors, when the motor load is smaller than a preset value, parts of walking wheels are taken as drive wheels, and when the motor load is larger than or equal to the preset value, all the walking wheels are taken as the drive wheels. According to the intelligent control system and method of the movable work shed, automatic movement, automatic deviation correction, automatic obstacle recognition and automatic risk alarming of the work shed along the preset track are realized, decentralized control systems of the work shed are integrated, construction control of operators is convenient, a control response effect of each system is improved, and series of risk accidents caused byoperational errors are avoided.

Description

technical field [0001] The present disclosure relates to the technical field of integrated control, in particular to an intelligent control system and method for a mobile shed. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] In order to prevent the dust, noise, mechanical vibration, and strong light at night caused by the construction of construction projects, which will also pollute the atmosphere and the living environment, construction sheds with different structures have appeared one after another, and the structure of the sheds has been continuously optimized and upgraded. Combined work shed, the work shed is equipped with multiple functional unit systems such as dust monitoring spray dust removal system, temperature monitoring spray cooling system, mobile equipment anti-collision sound and light alarm system, and the overall moveme...
