Problems solved by technology

In the prior art, in order to reduce non-working fuel consumption, the engine speed is usually reduced to enter the idling state to reduce fuel consumption. However, since the engine speeds up from idling to the target speed set for work, the speed-up time is too long, and the excavator controls the pump. The response of the solenoid valve still maintains a normal working state, and the change of the engine speed cannot keep up with the change speed of the solenoid valve, causing the excavator to freeze. In order to avoid the phenomenon of the excavator moving without reducing the engine speed, it will cause high fuel consumption. The problem

Embodiment 1

[0040] refer to figure 1 The flow chart of an idle speed control method for an excavator is shown, which is applied to the controller of the excavator and can be executed by electronic devices such as computers and processors. The method mainly includes steps S101 to S103:

[0041] Step S101, if it is detected that the excavator meets the preset speed reduction condition, reduce the working speed of the excavator to the first-stage idle speed. Wherein, the preset deceleration condition includes at least one of the following: the excavator startup command is not received within the preset first time period, the startup command of the automatic idle mode is received, and the excavator is detected not to change within the preset first time period. gear.

[0042] In a specific implementation manner, the operating speed of the excavator is reduced to the first-stage idle speed only when the preset speed reduction conditions are all met at the same time. An exemplary explanation is ...

Embodiment 2

[0058] refer to image 3 The schematic diagram of an excavator idle speed control device shown includes the controller of the excavator, and also includes:

[0059] The automatic deceleration unit 301 is used to reduce the working speed of the excavator to the first-stage idling speed if it is detected that the excavator meets the preset deceleration condition, wherein the preset deceleration condition includes at least one of the following: The start command of the excavator is not received within the first time period, the start command of the automatic idle mode is received, and it is detected that the excavator does not change gears within the preset first time period.

[0060] The command deceleration unit 302 is configured to reduce the idle speed of the first stage to the idle speed of the second stage if an idle speed instruction issued by the user is received.

[0061] The speed-up unit 303 is configured to raise the second-stage idle speed to the working speed if it...

Abstract

The invention provides an idle speed control method, device and control equipment of an excavator, which relate to the technical field of idle speed control and are applied to a controller of an excavator. If the start command of the excavator is not received within the preset first time period, the start command of the automatic idle mode is received and the gear position of the excavator is not changed within the preset first time period), the working speed of the excavator is reduced to the first level idle speed; if the idle speed command issued by the user is received, the first level idle speed is reduced to the second level idle speed; if it is detected that the excavator meets the preset The excavator changes the gear, receives the cancel instruction of the automatic idle mode of the excavator and receives the start instruction of the excavator), and increases the second-stage idle speed to the working speed. The invention can effectively reduce the stuck phenomenon of the excavator and reduce fuel consumption.

Description

technical field [0001] The invention relates to the technical field of idle speed control, in particular to an excavator idle speed control method, device and control equipment. Background technique [0002] At present, excavators are widely used in infrastructure construction and emergency rescue and disaster relief, and are indispensable and important equipment for engineering construction. Excavators generally use diesel engines as power sources, but they need to consume a certain amount of fuel. The fuel consumption of excavators mainly includes working fuel consumption and non-working fuel consumption. In the prior art, in order to reduce non-working fuel consumption, the engine speed is usually reduced to enter the idling state to reduce fuel consumption. However, since the engine speeds up from idling to the target speed set for work, the speed-up time is too long, and the excavator controls the pump. The response of the solenoid valve still maintains a normal worki...
