Control system for engineering machinery, control method and engineering machinery

Abstract

The invention relates to control technology, in particular to control technology for engineering machinery, which is used for remotely controlling the engineering machinery. An embodiment of the invention provides a control system for the engineering machinery and a control method for the engineering machinery. An electronic accelerator pedal is connected onto a remote controller, and an operatorcan remotely control an accelerator by stepping on the remote control accelerator pedal with feet when the operator cannot free two hands. The structure of the electronic accelerator pedal is identical with that of an accelerator pedal in a driving cab, the operator steps on the electronic accelerator pedal when needing to control the accelerator, and control signals of the electronic acceleratorpedal are transmitted to an engineering machinery controller through the remote controller, so that the accelerator is remotely controlled without affecting operation of the two hands of the operator, the operator can remotely control the engineering machinery by means of coordination of the hands and the feet, and the requirements of human engineering and operational humanization are met.

Description

technical field [0001] The invention relates to control technology, in particular to a control technology of engineering machinery. Background technique [0002] Rough-country tire cranes can complete the movement of materials or equipment under harsh natural conditions. Port operations and other aspects have a wide range of applications. Especially in areas with harsh construction environments such as deserts, Gobi and mountains, the superiority of rough terrain cranes can be demonstrated. [0003] During construction work, the operator needs to choose different outrigger support methods according to the different construction environments (including outrigger support area, boom luffing height limit, slewing operation conditions, etc.) and the weight of the hanging objects. When lifting heavy objects or rotating with heavy objects, the operator needs to correct the working state of the boom in real time according to the actual working conditions to ensure the safety of th...

AI Technical Summary

Problems solved by technology

[0008] 1. The operation and control of the off-road tire crane is completely carried out in the cab. The operator's line of sight is blocked by obstacles or affected by the angle of sight. to the correctness of the operator's next step

There are security risks

[0009] 2. If the rollover accident is caused by mechanical failure, human error operation, natural environmental factors or external force majeure factors, it will be very unfavorable to the personal safety of the operator because the operator cannot avoid the danger in time in the cab

[0010] 3. When the operator is in the cab, the line of sight will be affected to varying degrees

If there are dangerous devices such as high-voltage wires at the construction site of the rough-terrain tire crane, if the boom moves and touches the high-voltage wires, it is very easy for the operator to get an electric shock, which directly affects the life safety of the operator.

[0011] 4. If multiple staff members are added to overcome the limitations of one operator, repeated adjustments will occur due to the different positions, directions, and different understandings of things of each staff member, or the communication between each other is not timely and smooth. The action of the boom and hook greatly reduces the labor efficiency of production
