MULTI-SENSOR SIGNAL ACQUISITION AND DATA PROCESSING ANALYSIS OF COMBINE HARVESTER

Abstract

In recent years, combine harvesters are increasingly developing in the direction of large-scale, technology, automation and intelligence, and more and more electrical equipment is installed on combine harvesters. The electrical system of combine harvester is prone to failure when it works in high temperature, high humidity, dusty and strong vibration environment. Parameters to be adjusted in the header system of combine harvester include header height, drum height, drum front and back position, cutting frequency and drum speed. Aiming at the inconvenience of debugging and testing the measurement and control system of combine harvester in the field operation environment, an intelligent control test bed of combine harvester was designed. The test bed can simulate various intelligent control algorithms of combine harvester in laboratory environment, control the forward speed of combine harvester according to data processing results, classify faults, and send and print stored data through serial communication. Experiments show that the system works stably and reliably, and can realize the integration of the monitoring system of combine harvester operation process. It can save costs and improve efficiency in the application of the monitoring system of combine harvester.
