Method and system for improving starting capability of agricultural machine, controller and agricultural machine

Abstract

The invention relates to a method and a system for improving the starting capability of an agricultural machine, a controller and the agricultural machine. When it is judged that a preset emergency situation and any preset associated emergency situation in a preset associated emergency situation set occur at the same time according to the running state of the agricultural machine within a preset time period, the preset associated emergency situation is started; the idle speed of the engine is increased and maintained for the preset duration, on one hand, starting is achieved by increasing the rotating speed of the engine of the agricultural machine, namely increasing the idle speed, it can be guaranteed that the agricultural machine does not flame out, and the starting capacity of the agricultural machine is greatly improved; on the other hand, due to the fact that the idle speed of the engine is increased through automatic control, the fatigue strength of a driver is reduced; in addition, the rotating speed of the engine is accurately controlled, so that the situation that fuel economy is reduced is avoided, the situation that agricultural machinery is suddenly accelerated due to improper operation of a driver is also avoided, and the driving safety is guaranteed.

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 the agricultural machinery. Background technique [0002] Agricultural machinery generally carries a lot of load during operation. Under many working conditions, it will cause the agricultural machinery to reduce the engine speed to idle speed, that is, enter the idle state. Specifically: [0003] 1) For example, when the grain bins of harvesting machines such as corn / wheat harvesters and peanut harvesters are full, they will enter the idle state to wait for the unloading truck, and start to continue working after the unloading is completed; [0004] 2) For example, when a tractor is working on arable land, when it reaches the head of the field and needs to turn, it is necessary to reduce the engine speed to idle speed to ensure safe turning. After the turning is completed...

AI Technical Summary

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.
