Problems solved by technology
[0005] In the working conditions listed above, the engine of the agricultural machinery is in the idle state. When the starting operation is performed again, because the idle speed of the engine of the agricultural machinery is set to be low, it often leads to the slow start of the agricultural machinery or / and the phenomenon of flameout at start. happened
[0006] At present, the driver of the agricultural machinery starts by stepping on the accelerator pedal to increase the engine speed of the agricultural machinery, and can ensure that the agriculture does not turn off. However, on the one hand, the operation process is cumbersome and increases the fatigue of the driver; on the other hand , due to human operation, the engine speed cannot be precisely controlled, resulting in a decrease in fuel economy. Moreover, when the driver does not operate properly, it will also cause the agricultural machinery to accelerate suddenly, affecting driving safety.

Embodiment Construction
[0039] like figure 1 As shown, a method for improving the starting ability of agricultural machinery according to an embodiment of the present invention includes the following steps:
[0040] S1, according to the operation parameters of the agricultural machinery in the preset time period, obtain the operation state of the agricultural machinery in the preset time period;
[0041] S2. When it is determined according to the operating state of the agricultural machinery within the preset time period that the preset emergency situation and any preset associated emergency in the set of preset associated emergency situations occur simultaneously, the idle speed of the engine of the agricultural machinery is controlled to increase to Predetermined speed and maintain a preset time;
[0042] Wherein, the preset emergency situation is: when the opening degree of the accelerator of the agricultural machinery is reduced to 0, the reduction rate exceeds the preset opening degree reductio...

The invention relates to a method, system, controller and agricultural machinery for improving the starting ability of agricultural machinery. When it is determined according to the operating state of the agricultural machinery within a preset time period that a preset emergency situation and a preset associated emergency situation set occur simultaneously When any preset is associated with an emergency, increase the idle speed of the engine and maintain the preset time. On the one hand, by increasing the engine speed of the agricultural machinery, that is, increasing the idle speed to start, which can ensure that the agricultural machinery does not turn off and greatly improves the starting ability of the agricultural machinery. On the other hand, due to the automatic control, the idle speed of the engine is increased, the fatigue strength of the driver is reduced, and the engine speed is precisely controlled to avoid the decline of fuel economy, and also avoid the sudden acceleration of agricultural machinery caused by improper operation of the driver. to ensure driving safety.
Description
technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a method, system, controller and agricultural machinery for improving the starting ability of agricultural machinery. Background technique [0002] Agricultural machinery generally has a large load during operation. Under many working conditions, agricultural machinery will reduce the engine speed to idle speed, that is, enter the idle speed state, specifically: [0003] 1) For example, when the granary of harvesting machinery such as corn / wheat harvester, peanut harvester, etc. is full of grain, it will enter the idle state to wait for the unloading truck, and start to continue the operation after the unloading of the grain is completed; [0004] 2) For example, when the tractor is working on the farmland, when it needs to turn when it reaches the headland, it is necessary to reduce the engine speed to the idle speed to ensure a safe turn. After the turn is comple...
