Problems solved by technology

[0006] The purpose of the present invention is to solve the problem that the existing combine harvester cannot perform real-time monitoring and qualitative measurement of the feeding amount, which leads to inaccurate measurement, and provides an online monitoring device and monitoring method for the feeding amount of the rice-wheat combine harvester. Online monitoring of the feeding amount of the combine harvester ensures the best working performance and the best harvesting status of the combine harvester, improves the working quality and efficiency, reduces grain loss, and reduces the machine damage rate

Abstract

The invention discloses an on-line monitoring system for feed quantity of a combine harvester and a monitoring method thereof. The on-line monitoring system for the feed quantity of the combine harvester comprises a power monitoring device for monitoring the rotation speed vr and the power Pj of a power shaft of a cutting table auger, a cereal grain flow monitoring device for monitoring the flow Qg of harvested cereal, a stem flow monitoring device for monitoring discharged stems of the combine harvester and a vehicle-mounted monitoring controller, wherein the vehicle-mounted monitoring controller is in communication connection with the power monitoring device, the cereal grain flow monitoring device and the steam flow monitoring device respectively; Qg, Qc, vr and Pj are used as training samples by the vehicle-mounted monitoring controller; optimization is performed by using a BP (Back Propagation) neural network model to obtain real-time feed quantity qd of the combine harvester. According to the on-line monitoring system for the feed quantity of the combine harvester and the monitoring method thereof, the feed quantity of the current combine harvester is calculated by using a multi-sensor information fusion algorithm, the measurement 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...
