Problems solved by technology

[0008] The technical problem to be solved in the present invention is to provide an excavator operation mode confirmation method and system and a control method and system for the problem that the existing excavator starts to work or the operation mode is switched and the operation mode confirmation is insufficient and easily causes safety accidents. Fully confirm the operation mode after the excavator starts working or the operation mode is switched to avoid potential safety hazards caused by the inconsistency between the actions performed by the machine and the operator's expected operation

Embodiment Construction

[0054] The specific implementation will be described below in conjunction with the accompanying drawings.

[0055] Such as figure 1 As shown, the excavator control system in this embodiment includes a hydraulic oil tank 1, a joystick 2, a touch display 3, a control unit 4, an electric proportional valve 5, a boom main control valve 6, a boom cylinder 7, and a pilot switch 8 , pilot pump 9, main pump 10, engine 11.

[0056] In the excavator control system, in addition to the boom main control valve 6 , the main control valve also includes a bucket main control valve, an arm main control valve, a swing main control valve, etc. which are not shown in the figure. In addition to the boom cylinder 7, the hydraulic actuators also include bucket cylinders, stick cylinders, swing motors, etc. not shown in the figure. The electric proportional valve 5 is an eight-connection proportional solenoid valve, and every two connections control a main control valve.

[0057] The engine 11 dr...

Abstract

The present invention relates to excavator control, in order to solve the problem that the existing excavator has no confirmation or insufficient confirmation of the operation mode after the operation mode is switched, and the process is cumbersome and time-consuming, which is easy to cause safety accidents; it provides a method for confirming the operation mode of the excavator and The system and control method and system, wherein the method for confirming the operation mode of the excavator includes the following steps: setting the excavator to the slow-motion safety mode state, and controlling the excavator to perform the operation corresponding to the handle operation signal according to the operation mode to be confirmed according to the handle operation signal Excavation action; set the operation mode to be confirmed as the current operation mode of the excavator and set the excavator to the normal working mode. In the present invention, when any control handle or pedal is operated to confirm the operation mode, the excavator produces a slow motion corresponding to the operator's intended direction, which intuitively reflects the operator's intention and the corresponding logical direction of the excavator's action in the operation mode to be confirmed Digging action for easy operation mode confirmation.

Description

technical field [0001] The present invention relates to an excavator control, more specifically, to an excavator operation mode confirmation method and system, and a control method and system. Background technique [0002] The existing electronically controlled excavation includes a controller, a handle connected to the controller, various proportional valves controlled by the controller to realize various operation actions, and a touch display device for displaying machine settings, status and setting machine operation modes. In a certain set operation mode, the controller controls the corresponding proportional valve according to the input signal of the handle, so that the working device of the excavator realizes the corresponding action. The signal output by the handle corresponds to the swing direction of the handle, and there are only four swing directions for each handle, that is, swing forward, backward, left, and right. Excavators are usually equipped with left and ...
