Embodiment 1

[0064] Such as figure 1 As shown in FIG. 1 , it is a schematic flowchart of a method for controlling the idle state of the engine provided by Embodiment 1 of the present invention. The method can be described as follows.

[0065] Step 101: Obtain current working status information of the crane.

[0066] Wherein, the working state information includes the hoisting state information of the crane, the rotational speed information of the engine, and the instruction information.

[0067] In step 101, the crane is turned on, and the engine of the crane is started to work.

[0068] Usually, when starting the engine of the crane, it is necessary to initialize the parameter information of the engine, clear the flag information of the engine, and reset the counters to zero.

[0069] Specifically, each flag bit of the engine includes, but is not limited to: a flag bit that allows stopping (ie, AutoStopEnable); and a flag bit that allows starting (ie, AutoStartEnable).

[0070] The ti...

Embodiment 2

[0110] Such as image 3 As shown, it is a schematic flow chart of a method for controlling the idle state of the engine provided by Embodiment 2 of the present invention. Embodiment 2 of the present invention is a detailed description of each step in Embodiment 1 of the present invention. The method can be described as follows.

[0111] Step 201: Start the engine of the crane.

[0112] Usually, when starting the engine of the crane, it is necessary to initialize the parameter information of the engine, clear the flag information of the engine, and reset the counters to zero.

[0113] Specifically, each flag bit of the engine includes, but is not limited to: a flag bit that allows stopping (ie, AutoStopEnable); and a flag bit that allows starting (ie, AutoStartEnable).

[0114] The timers of the engine include but are not limited to: idle timer (ie IdleTime); stop timer (ie EngineStopTimer); pedal timer (ie PedalTime); start timer and stop timer, etc.

[0115] Step 202: Obt...

Embodiment 3

[0146] Such as Figure 4 As shown, it is a schematic structural diagram of a device for controlling the idle state of the engine provided by Embodiment 3 of the present invention. Embodiment 3 of the present invention is an invention under the same inventive concept as Embodiment 1 and Embodiment 2 of the present invention. , the device includes: an acquisition module 11 and a control module 12, wherein:

[0147] The obtaining module 11 is used to obtain the working state information of the current crane, wherein the working state information includes the hoisting state information of the crane, the rotational speed information of the engine, and the instruction information;

[0148] The control module 12 is configured to determine, according to the working state information, that the crane is in a non-working state with no load and the engine of the crane is in an idling state, and send an instruction to stop working to the engine of the crane.

[0149] Specifically, the contr...

Abstract

The invention discloses a method for controlling the idle state of an engine, equipment and a crane. The method comprises the following steps: acquiring the working state information of the current engine, wherein the working state information comprises the suspended load state information of the crane, the rotating speed information of the engine and instruction information; determining that the crane is under a suspended load in a non-working state and that the engine of the crane is in an idle state according to the working state information, and sending a work stopping instruction to the engine of the crane. When the working state information of the current crane is acquired, the crane is under the suspended load in the non-working state and the engine of the crane is in the idle state according to the working state information according to determination, and the work stopping instruction is sent to the engine of the crane in time in order to keep the engine of the crane in the non-working state, thereby avoiding the situation of oil consumption in the idle state of the engine, saving the use cost of the crane, and prolonging the working time of the engine.

Description

technical field [0001] The invention relates to the technical field of crane control, in particular to a method, equipment and a crane for controlling the idling state of an engine. Background technique [0002] In the field of engineering technology, the role of cranes is mainly to lift heavy objects. That is to say, when the crane is lifting heavy objects, the engine is always in working condition. But according to on-site construction needs, there is a situation that the crane does not lift heavy objects. At this time, the operator of the crane will make the engine of the crane in an idle state, so that the engine of the crane waits for the next operation instruction in this state. [0003] It should be noted that the so-called idling state refers to a state where the engine is not accelerating and the minimum operating speed of the engine is maintained. [0004] In practical application, the length of time that the engine of the crane is in the idling state varies. Whe...
