The Design And Implementation Of Remote Monitoring System For Tractor Based On Tractor Of Internet

The twenty-first Century is the era of internet.The rapid development of the Internet provides more and more convenience for human life and work.However,car of internet was to provide a new development direction for the automobile industry in 2010,after several years of development has become the hottest research fields.For agricultural,also providing a new opportunity for development,we meet the agricultural vehicle machinery to the trend of the development of the Internet,the tractor of internet may be put forward.The tractor internet system can realize the communication between the tractor and tractor,and communicate with remote control center,and realize the sharing of information,and form a complete network system,which called as tractor of internet.Firstly,this paper analyzed the domestic and international research,we can see that the development of agricultural vehicle machinery field quickly,continue to introduce a variety of cutting-edge technology,such as GIS technology,GPS technology,sensor technology,wireless communication technology and so on.For the application of wireless remote monitoring in the field of agriculture was still relatively rare,only a small part of remote monitoring the field information,the system was still not perfect,in the application of agricultural vehicle machinery was less.At present,the agricultural machinery monitoring was used on some large joint harvesting and tractors,and remote monitoring information was not complete and not enough.Combining with the current situation of' research subject,based on the design of tractor of internet remote monitoring system,realize the real-time monitoring of the tractor work information and video image.Secondly,the paper on the tractor of internet system of overall design,the tractor working information in the field acquisition the data by mobile terminal,and then uses the mobile Internet connected to the Internet,and the data is returned to the data control center.Data control center using the server software for receiving data,and stored in the database,and the client displays real-time data from the remote.The selection and calibration of hardware and sensors ensure that the system has low power consumption and high performance hardware support.Then complete the framework design of the wireless video monitoring system,positioning parameters monitoring system,and finish the technical route of writing system.Then,paper complete the tractor of internet system software design,and complete tractor of internet client software design,which has the system account and management,and based on streaming media video surveillance,and baidu map location monitoring and operating parameters of the display,and preservation program design.The paper gives a specific program design process.Then,the paper design the client interface based on display the tractor information with good monitoring interface,and realize the friendly man-machine interactive function.The interface has reasonable layout of content,and using Photoshop software design machine network monitoring software icon,borders and backgrounds and so on.In the fifth chapter,the paper propose that using adaptive Kalman filter to improve GPS positioning accuracy to accurately measure the tractor operation area.The adaptive Kalman filtering algorithm was mainly to solve the problem of the degradation of the system's filtering accuracy and the divergence of the system in the case of unknown noise statistics,or not accurate.Then gauss projection algorithm was used to change the longitude and latitude data into plane coordinates to calculate the area.To test and verify the influence of different ways of operation on the operation efficiency,chosen back tillage,spindle tillage and alternative plough method to cultivated land.In order to test GPS area measuring precision,it was preparation for its work in the field area measurement.This research used the GPS to measure some regulation figures and irregular figures.With the measurement area increasing,measurement accuracy was higher.The most efficient farming method was alternative tillage,and the second was spindle tillage.Back tillage's balk rate was highest,and operating efficiency was lowest.At last,the paper makes a combination of hardware and software to verify the reliability and stability of the system.The driving and debugging of the driving and debugging of the video monitoring,the driving and debugging of the positioning and monitoring,the driving and debugging of the working parameters are finished.The test results show that the system function is basically normal.
