Abstract:To solve the present stage combine monitor system lack of remote network interconnection and remote monitoring ability of operating data and fault information, this paper developed an information monitoring system for main parts working condition of combine harvester based on Android mobile phone.On the basis of combine local monitoring system, we can achieve effective monitoring and fault information processing for revolution speed of threshing cylinder, a stirring dragon speed and similar parameters, and realize Android client remote operation and fault information monitoring.Mainly through the C8051F020 microprocessor connected with multi hall sensor, the key information of the main working parts, such as revolution speed of threshing cylinder, stirring dragon speed, was acquired. C8051F020 through UART0 serial interface with SIM900A module and SIM900A module sent a TCP connection request to the China mobile internet open platform server. Then the data was received by a Android smart phone based on network platform in real time. Using the fault diagnosis method based on the instantaneous variation trend of the target signal in the single chip microcomputer for fault diagnosis, transmitted fault information of condition monitoring was used to realize real time monitoring for combined harvester critical information and fault diagnosis. Simulation tests showed that the lower computer acquisition system, server and client performance were stable, data loss rate was controlled within (less than) 5%, information access delay time was less than 2s with alarm in time and correctly, and was able to meet the requirements of remote information acquisition and fault monitoring when combine harvesters work outdoors.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
