Problems solved by technology

[0002] At present, most of the traditional loaders use manual operation of the boom and bucket operating lever, and use the pilot hydraulic principle to execute the system and control the movement of the vehicle; High strength, easy fatigue, and safety issues are difficult to guarantee; in rainy and snowy weather or under slippery road conditions, slippage occurs when digging materials, which is difficult to dig and lead to low work efficiency; unskilled operators need a long period of on-the-job training, safety Big hidden dangers seriously affect work efficiency; the above three aspects all affect the fuel consumption of the vehicle, and reduce the operating comfort during frequent operations

Embodiment 1

[0032] Such as figure 1 As shown, a loader shovel anti-slip control method provided in an embodiment of the present invention includes the following steps:

[0033] In response to detecting that the loader is in a slipping state, an instruction is sent to the boom cylinder 11 to control the boom cylinder 11 to perform a lifting action until it is detected that the loader is in a non-skidding state or the stroke of the boom cylinder 11 meets the preset first stroke requirement;

[0034] In response to detecting that the loader is in a non-slip state, an instruction is issued to the bucket cylinder 12 to control the bucket cylinder 12 to perform the action of retracting the bucket until it is detected that the loader is in a slipping state or the stroke of the bucket cylinder 12 meets the preset second stroke requirement .

[0035] The preset first stroke requirement is that the stroke of the boom cylinder 11 reaches the set threshold value, and the preset second stroke require...

Embodiment 2

[0040] Such as figure 2 and image 3 As shown, a loader shovel anti-slip control method provided in an embodiment of the present invention includes the following steps:

[0041] S1. After the vehicle is powered on, collect relevant signals of the control system, judge the correctness of various signals online, and make judgments from time to time;

[0042]S2. Determine whether the collected signal is faulty, if so, execute S3; if not, execute S5;

[0043] S3. According to the failure situation, control the bucket or the boom to stop and give an early warning or alarm;

[0044] S4. According to the execution situation of S3, trigger corresponding voice, flash the fault flashing indicator light 22 according to the fault code, store and upload data to the remote online monitoring platform;

[0045] S5. The operator puts the arm and bucket of the loader to the position to be shoveled, activates the switch 6 in the operation mode, enters the automatic trigger activation state o...

Embodiment 3

[0056] Such as figure 1 As shown, a loader shovel anti-skid control system provided by an embodiment of the present invention includes:

[0057] Boom lifting module: in response to detecting that the loader is in a slipping state, issue a boom cylinder 11 command to control the boom cylinder 11 to perform a lifting action until it is detected that the loader is in a non-skidding state or the stroke of the boom cylinder 11 meets the preset first trip requirements;

[0058] Bucket retracting module: in response to detecting that the loader is in a non-slip state, issue a bucket cylinder 12 command to control the bucket cylinder 12 to perform bucket retraction until it is detected that the loader is in a slipping state or the stroke of the bucket cylinder 12 meets the predetermined Set second trip requirements.

Abstract

The invention discloses an anti-skid control method, system and device for spading of a loader. The method comprises the steps: sending a boom cylinder instruction in response to the detection that the loader is in a skid state, and controlling a boom cylinder to perform a lifting movement until it is detected that the loader is in a non-skid state or the stroke of the boom cylinder meets a preset first stroke requirement; and sending a bucket cylinder instruction in response to the detection that the loader is in the non-skid state, and controlling a bucket cylinder to perform a bucket retracting movement until it is detected that the loader is in the skid state or the stroke of the bucket cylinder meets a preset second stroke requirement. The intelligent level of the loader is improved, the slipping phenomenon during material spading is prevented, and the safety is improved; the device is applicable to working conditions influenced by factors such as rainy and snowy weather or road slip, slipping is prevented, the work efficiency is not reduced, and the spading work is automatically completed; the effectiveness of the operation is greatly improved, and the work efficiency is improved; and energy conservation and emission reduction are achieved, unmanned development of engineering machinery is promoted, and good application prospect is achieved.

Description

technical field [0001] The invention relates to a loader shoveling anti-skid control method, system and device, belonging to the technical field of shoveling machinery intelligent control. Background technique [0002] At present, most of the traditional loaders use manual operation of the boom and bucket operating lever, and use the pilot hydraulic principle to execute the system and control the movement of the vehicle; High strength, easy fatigue, and safety issues are difficult to guarantee; in rainy and snowy weather or under slippery road conditions, slippage occurs when digging materials, which is difficult to dig and lead to low work efficiency; unskilled operators need a long period of on-the-job training, safety The hidden danger is big, which seriously affects the work efficiency; the above three aspects all affect the fuel consumption of the whole vehicle, and reduce the operating comfort during frequent operation. Contents of the invention [0003] The purpose...
