The combine harvester operation state online monitoring system has the advantages of good wiring simplicity, good mounting convenience, high fault detection accuracy, good extensibility and the like.

Description

technical field [0001] The invention relates to an online monitoring system for monitoring the working state of a combine harvester. Background technique [0002] Combine harvesters can perform multi-functional operations such as harvesting, threshing, separating stems, and removing debris. There are many and complicated functional components. Therefore, if online detection of the working conditions of each functional component is required, a large number of sensors need to be arranged, which will inevitably lead to complicated wiring. , It is neither conducive to installation nor easy to maintain and replace. In the prior art, due to the complexity of the wiring, the monitoring of the working state of the combine harvester often only involves the torque monitoring of the key shaft components, lacking the speed monitoring of the key shaft components and the monitoring of the fault-prone parts. In this way, it is not conducive to the accurate judgment of the combine harveste...

[0002] Combine harvesters can perform multi-functional operations such as harvesting, threshing, separating stems, and removing debris. There are many and complicated functional components. Therefore, if online detection of the working conditions of each functional component is required, a large number of sensors need to be arranged, which will inevitably lead to complicated wiring. , which is neither conducive to installation nor easy to maintain and replace

In the prior art, due to the complexity of the wiring, the monitoring of the working state of the combine harvester often only involves the torque monitoring of the key shaft components, lacking the speed monitoring of the key shaft components and the monitoring of the fault-prone parts

In this way, it is not conducive to the accurate judgment of the fault of the combine harvester, and it is impossible to propose a reasonable fault solution in time.
