Problems solved by technology

However, the urban construction environment is complex, surrounded by obstacles such as electric wires, optical cables, walls, etc., and accidents occur frequently during construction operations, which restricts the construction work of excavators and affects the safe construction of excavators.
[0003] In the prior art, electronic fences are used to limit the construction scope of the excavator. When it is detected that the angle of the bucket operation at the end of the excavator exceeds the set upper limit angle, the controller sends an alarm message and controls the excavator to stop. In this way, when the excavator is working, there is a problem that the bucket is forcibly stopped just after touching the edge of the electronic fence

Abstract

The invention provides a work method of an electronic fence for an excavator, the electronic fence and the excavator, and relates to the technical field of electronic fences. The work method comprisesthe steps of obtaining preset excavator running parameter threshold values, first parameter difference threshold values and second parameter difference threshold values, and when the excavator works,obtaining actual excavator running parameters in real time during work of the excavator; if it is detected that the parameter differences between the preset excavator running parameter threshold values and the actual excavator running parameters are not larger than the first parameter difference threshold values, sending out a first alarm signal; and if it is detected that the parameter differences between the preset excavator running parameter threshold values and the actual excavator running parameters are not larger than the second parameter difference threshold values, sending a second alarm signal, and controlling the excavator to stop action. Therefore, before the excavator stops action, a pre-warning process exists, and enough reaction time is left for drivers.

Description

technical field [0001] The present application relates to the technical field of electronic fences, and in particular, to an operation method of an electronic fence for excavators, an electronic fence and an excavator. Background technique [0002] With the continuous increase of urbanization, excavators are widely used in urban construction to improve the operation efficiency of projects. However, the urban construction environment is complex, and there are obstacles such as wires, optical cables, and walls around. Accidents occur frequently during construction operations, which limit the construction operations of excavators and affect the safe construction of excavators. [0003] In the prior art, an electronic fence is used to limit the construction work range of the excavator. When it is detected that the angle of the bucket operation at the end of the excavator exceeds the set upper limit angle, the controller sends out an alarm message and controls the excavator to st...
