Hydraulic-digger obstruction-avoiding control system and method

Abstract

This invention discloses a hydraulic pressure excavator to evade bonds control system and the method. Including the following step: (1) hypothesis unearths the forbidden area; (2) gains the excavator through the sensor of move arm, the bucket arm, the scoop and the working platform condition; (3) computation excavator work installs and unearths the forbidden area the distance, when this distance being smaller than marginal value, sends out the alarm; (4) redundant step (2), (3), until excavator engine off when up to; The system including input device's load module, uses in examining the excavator work, walking the setting position angle sensor, the inclination angle sensor, various sensors' output signal after the sensor interface module and the controller connection, is equipped with the comparison module the controller as well as the early-warning installation. This invention the online data which and the critical number comparison obtains through various sensors, the definite excavator's active status, realizes in the excavator work process by this to the obstacle avoidance function, avoids the accident occurring.

Description

technical field [0001] The utility model relates to a hydraulic excavator, in particular to a system and method for providing obstacle avoidance control for the hydraulic excavator. Background technique [0002] Hydraulic excavators are widely used in foundation excavation of housing construction and cleaning after completion, urban pipeline laying, farmland water conservancy construction and other occasions. It has the advantages of flexible construction and high efficiency. [0003] There are often some obstacles that need to be avoided in the working area of ​​hydraulic excavators, such as underground pipelines, house foundations, utility poles, etc. It can be considered that these obstacles divide the excavation space into two parts: the excavable area and the excavation restricted area. It has brought constraint conditions for the trajectory of the front end working device of the excavator. If the front end working device of the excavator hits these obstacles, it will c...

Problems solved by technology

[0003] There are often some obstacles that need to be avoided in the working area of ​​hydraulic excavators, such as underground pipelines, house foundations, utility poles, etc. It can be considered that these obstacles divide the excavation space into two parts: the excavable area and the excavation restricted area. It brings constraints on the trajectory of the front-end working device of the excavator. If the front-end working device of the excavator encounters these obstacles, it will cause accidents and cause losses

[0004] At present, excavator obstacle avoidance mainly depends on the operator's proficiency in operation. However, because the above obstacles are located underground, it is inconvenient to observe, and the operation accuracy of the excavator is also difficult to control. Relying on the ability of the operator cannot reliably avoid accidents.
