Online monitoring system of harvester and monitoring method thereof

Abstract

The invention discloses an online monitoring system of a harvester and a monitoring method thereof. A harvester feeding amount online monitoring system comprises a monitoring device which is used formonitoring the rotation rate vr and power Pj of a power shaft of a cutting platform auger, a grain seed flow amount monitoring device which is used for monitoring the grain flow amount Qg, a stalk flow amount monitoring device which is used for monitoring the flow amount Qc of stalk discharging of the harvester and a vehicle-mounted monitoring controller, the vehicle-mounted monitoring controlleris in communication connection with the power monitoring device, the grain seed flow amount monitoring device and the stalk flow amount monitoring device, wherein Qg,QC, vr and Pj are taken as training samples by the vehicle-mounted monitoring controller, and a BP neural network model is adopted to perform optimization to obtain the real-time feeding amount qd of the harvester. According to the system, a multi-sensor information fusion algorithm is adopted by the online monitoring system and the monitoring method thereof, the feeding amount of a current harvester is calculated, the measuring is accurate, and the use is convenient.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery intelligent monitoring, and relates to an online intelligent monitoring device for the feeding amount of a rice and wheat combine harvester and a monitoring method using the device. Background technique [0002] A combine harvester is a complex dynamic system with multiple input and output variables. When the combine harvester is working, the cutter first cuts the grains, and the conveying chain rake of the inclined conveying trough feeds the crops to the threshing drum to separate the grain and grass, and the stalks are discharged from the grass discharge port at the tail of the combine harvester. The grains, short stalks The separated mixture such as waste and debris falls into the shaking plate through the concave plate sieve, and then enters the cleaning system for cleaning, and the cleaned grains are transported to the grain tank. The combine harvester is designed according to...
