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, drum speed, 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.

近年来，联合收割机日益向大型化、技术化、自动化和智能化方向发展，联合收割机上安装的电气设备越来越多。联合收割机在高温、高湿度、多灰尘和强振动环境中工作，其电气系统容易出现故障。联合收割机割台系统中需要调整的参数包括割台高度、滚筒高度、滚筒前后位置、滚筒速度、切割频率和滚筒速度。针对联合收割机测控系统在田间作业环境下调试和测试的不便，设计了一种联合收割机智能控制试验台。该试验台可以在实验室环境下模拟联合收割机的各种智能控制算法，根据数据处理结果，控制联合收割机的前进速度，进行故障分类处理，并通过串行通信发送和打印存储的数据。实验表明，该系统工作稳定可靠，能够实现联合收割机作业过程监控系统的一体化，在联合收割机测控系统的应用中能够节约成本，提高效率。
