Research and application of Netty based condition monitoring system for forage harvesting machine

Abstract In order to realize intelligent monitoring of main components of forage harvesting machine, an intelligent remote monitoring system based on CAN bus technology, Socket communication protocol based on Netty framework and cloud server was designed to solve the problem of low level of informatization of forage harvesting machine in China. system includes data acquisition system, data wireless transmission module and cloud data storage and analysis and processing system, realizing the data synchronization and sharing of working condition information of forage harvesting machine at local, cloud and mobile terminals. We developed the on-board terminal system based on Labview platform, and the web server based on SpringBoot framework. The parameters obtained by the sensor mainly include vehicle position information, engine speed and torque, shredding roller, grain crushing roller, cutting table, feeding, throwing, motor and other core components. Field experiments for 15 consecutive days show that: cloud server system with custom Socket communication protocol receives and stores terminal data in real time; The monitoring platform can realize the functions of data display and curve display of working condition information, data analysis and intelligent information reminder. By analyzing the data curve of the main components, the stability and reliability of the system are verified, which is of great significance to the informationization and intelligent development of the machinery and equipment of the forage harvesting machine.
