Embodiment 1

[0032] see figure 1 , An embodiment of the present invention provides a weighing system for an excavator, including: a boom position sensor, an arm position sensor, a bucket position sensor, an oil pressure sensor and a controller. The boom position sensor is arranged at the boom position of the excavator, and the boom position sensor is electrically connected with the controller; the boom position sensor is used to detect the position parameters of the excavator boom. The stick position sensor is arranged at the position of the boom of the excavator, and the stick position sensor is electrically connected with the controller; the stick position sensor is used to detect the position parameter of the stick of the excavator. The bucket position sensor is arranged at the bucket position of the excavator, and the bucket position sensor is electrically connected with the controller; the bucket position sensor is used to detect the bucket position parameters of the excavator. The o...

Embodiment 2

[0040] Embodiments of the present invention also provide a method for weighing an excavator, comprising the steps of:

[0041] Step S10, setting the boom position parameters, arm position parameters and bucket position parameters of the excavator in the weighing state; Functional relational model.

[0042] Step S20, obtain the loading signal of the excavator, and send a control signal to control the movement of the boom, stick and bucket of the excavator after the loading signal is obtained; when the position parameters of the boom, stick and bucket of the excavator reach When the position parameters are set in the weighing state, a control signal is sent to control the boom, arm and bucket of the excavator to stop.

[0043] Step S30, when the position parameters of the boom, arm and bucket of the excavator reach the set position parameters in the weighing state and stop the action, obtain the current oil pressure value from the oil pressure sensor; It is input into the mode...

Abstract

The invention belongs to the technical field of excavators and relates to a weighing system and method of an excavator. The weighing system comprises a movable arm position sensor, a bucket rod position sensor, an excavator bucket position sensor, an oil pressure sensor and a controller; the movable arm position sensor is arranged at the position of a movable arm of the excavator and electrically connected with the controller; the bucket rod position sensor is arranged at the position of a movable arm of the excavator; the bucket rod position sensor is electrically connected with the controller; the excavator bucket position sensor is arranged at the position of an excavator bucket of the excavator, and the excavator bucket position sensor is electrically connected with the controller; and the oil pressure sensor is arranged on a hydraulic oil cylinder of the movable arm of the excavator. According to the weighing system of the excavator, the excavator is operated to a specific posture after performing excavation; the excavation weight is calculated according to a function relation between the oil pressure of a main oil tank and the excavation weight of the excavator; and thus, weighing system is convenient and practical.

Description

technical field [0001] The invention relates to the technical field of excavators, in particular to a weighing system and method for an excavator. Background technique [0002] Excavators often need to weigh their internal weight during use to achieve refined and quantitative construction requirements. Due to the special structure of the excavator, it is difficult to weigh the materials excavated by the excavator. At present, although the industry provides some weighing solutions for the materials excavated by the excavator, they are relatively complicated and difficult to be widely used in production. implement. Contents of the invention [0003] Aiming at the technical problem that it is difficult to weigh an excavator in the prior art, the invention provides a weighing system and method for an excavator. [0004] The technical scheme that the present invention solves the problems of the technologies described above is as follows: [0005] A weighing system for an exc...
