[Abstract]:With the development of agricultural mechanization level and the rapid development of agricultural information level, the management of agricultural machinery equipment is becoming more and more important. However, the traditional agricultural machinery management is not in place, the efficiency is low, the cost is high, the agricultural equipment is not reasonable, the original data is easy to lose, the data query is difficult, the agricultural machine operation condition is not clear, the safety hidden danger is many, the maintenance difficulties, machinery machinery are difficult. Many problems, such as the uncertainty of performance parameters, the difficulty of the training of the machine hand and so on, can not be solved quickly. The agricultural machinery management is becoming more and more necessary. Because the Android platform is widely used for its remarkable openness and wide free development environment, a large number of functional and convenient mobile APP software have been developed. Some domestic scholars have closed the agricultural machinery management APP. The key technology has been studied, and some enterprises have developed their own APP system of agricultural machinery management. Although some outstanding problems in agricultural machinery management have been solved, there are simple system functions, single interface and independent data sharing among various agricultural machinery management APP, which are only "pipe" and "pipe", and the intelligence is poor and is not easy. In order to solve the above problems, this research is to collect the information of agricultural machinery technical parameters and operation state in the equipment end of agricultural machinery equipment, and upload it to the handset of the machine by Bluetooth, and fuse the GPS/GIS data information and weather information in the mobile phone, then upload it to the Internet network through the 3G or 4G network, and upload it to the backstage center computer in real time. The measurement data, real-time remote monitoring of agricultural machinery technical status and operation state, realizing agricultural machinery operation management, on-line training of machine hand, function of agricultural machinery policy and information sharing, providing basis for equipment evaluation and investment decision, and realizing linkage between agricultural machinery users, management institutions, design and production enterprises, after-sale maintenance, spare parts supply and operating objects. The data provides the basic data and can also share the large data. The main contents of the research include: (1) the overall structure of the system is designed. The design of the hardware design of the mobile terminal data acquisition and the APP software design of agricultural machinery management, the framework and function of the system are designed, the system development means and processes are described, and the technical state of agricultural machinery is determined. To determine and move the function of the data acquisition system, interface and data upload mode, the function module of APP application software based on Android mobile machinery intelligent management is designed. (2) the mobile terminal data acquisition system is designed and built. The module design principle is used to divide the data acquisition system of the EMU to the sensor collection and Processing module, control module, storage module and wireless transmission module based on Bluetooth, and five types of sensor interface circuits based on CAN bus voltage sensor, current type sensor, digital sensor and frequency type sensor are designed to meet the collection of various technical state parameters of agricultural machinery equipment, and each type of sensor interface is used. The control module also uses CAN bus communication; the working state parameters of agricultural machinery equipment can not only be uploaded to the handset by the Bluetooth module, but also can be stored in the storage module to facilitate the query of historical data. (3) using the location data of the mobile phone GPS/A-GPS and integrating the agricultural GIS system, the precise positioning of agricultural machinery equipment is studied. Based on the location service data of the smart phone A-GPS, as the location parameter of agricultural machinery equipment, the positioning precision is greatly improved, the agricultural GIS system is fused, and the coordinate values of the agricultural machinery are eliminated and the arithmetic average processing is used to obtain the accurate position of agricultural machinery and the latitude sitting information, which provides the basis for the calculation of the operating area of agricultural machinery equipment. (4) the operation area algorithm based on envelope line is proposed and studied in detail. The operation area algorithm based on envelope line refers to the real-time collection of agricultural machinery geographical location information, select the coordinate value of the movement boundary point of agricultural machinery operation, and use the curve fitting method to solve the function analytic formula of the boundary packet line, and further use the integral method to find out. To unpack the area of the collaterals, the area of the area is the operating area of the farmland area. (5) the "intelligent agricultural machinery management system" software based on the Android mobile phone is developed. Through the analysis of the application requirements, four modules are set up, including agricultural machinery operation, agricultural machinery service, machine hand training and agricultural machinery and hand information, and each module is set under each module. The development process and design requirements of the system are described in detail. The construction of the software development environment is described in detail. The function of the software development and the calling relationship of each part are designed. (6) a test platform is built, and the functions, location, monitoring and operation area of the system are tested. The test results show that: The system runs steadily, the function is effective and the positioning accuracy is obviously improved compared with the traditional GPS positioning. The relative error of the agricultural machinery area is about 1.4%~2.085% in the air area of 400m21000m21600m22000m2, and the envelope area method is under two operating modes under full amplitude operation mode and overlapping operation mode. The result shows that there is little change in the error. The envelope method can effectively prevent overlapped operations.
