[Abstract]:With the rapid development of China's economy, large-scale operation machinery plays a more and more important role in the national economic base sectors such as agriculture, manufacturing and construction. Networking, information technology and intelligent technology are constantly introduced into the traditional large-scale operation machinery maintenance and management. In this paper, based on the sensor network (SensorWeb), the remote positioning, mobile communication and data processing technologies are integrated into the large-scale operation machinery, and a long-distance monitoring system for large-scale operation machinery is designed, which can be trimmed in software and hardware and has good real-time performance. This system takes Exynos4412 of Samsung company as the information processing center, sends the monitoring status information to the Exynos4412 processor through the sensor network, and completes the system data interaction through the communication module. The main contents of this design are as follows: (1) the wireless and wired network construction mode of sensor network (SensorNetwork) is studied. Combined with the characteristics of long-distance monitoring of large-scale operation machinery, CAN bus is adopted as the physical layer communication mode of sensor network. The whole scheme of remote monitoring is designed, and the system is divided into sensor network, front-end controller, remote monitoring center and on-site monitoring terminal. (2) the hardware of the system is developed according to the requirements of function and performance. The circuit design of positioning module and hardware circuit of wired communication module, wireless communication module and sensor network communication module are completed. Video data, vibration data, stress data and temperature data acquisition circuit are designed. A general-purpose power management module is designed for the built-in power level of large-scale operating machinery. (3) the Linux driver and kernel design based on Samsung Exynos4412 platform are completed. The system is transplanted through OTG. (4) the data analysis and software design of positioning module are completed, and the software of wireless communication module and CAN communication module is designed. The software of video and sensor data acquisition circuit is designed. (5) the wireless communication protocol between front-end controller and remote monitoring center is designed. Finally, the designed monitoring system is installed on the large-scale agricultural machinery Dongfanghong LF2204, and the function test of the remote monitoring system is carried out through the remote monitoring center. The test results show that the system can achieve the status information acquisition and remote control of large-scale operation machinery, and provide technical reference for intelligent management of large-scale operation machinery, such as management and scheduling, precision operation and so on.
