With the rapid development of agricultural economy, modern agriculture has been gradually realized mechanization. In recent years, the development of electronic information technology to promote the intelligent development of agricultural machinery technology, which also means that the mechanical equipment on the control unit is increasing, and the CAN bus technology applied to agricultural machinery, can greatly facilitate the integration of the control unit assembly and maintenance.

ISOBUS 11783 standard

The lack of compatibility between technology platforms and agricultural machinery is a long-standing problem for smart agriculture practitioners, and it is also a huge challenge for improving productivity. Although there are many proprietary solutions for the technology, the lack of interaction between the components makes it difficult for agricultural machinery to fulfill its various functions. In order to solve this problem, the International Organization for Standardization (ISO)Developed the communication protocol ISOBUS standard (ISO11783).It is used as a common protocol for electronic communications between implements, tractors and computers.

The ISOBUS standard (ISO11783) is used in the field of agricultural machinery, such as tractors, combine harvesters, seeders, irrigation equipment, etc. ISOBUS is based on standard CAN bus technology, andBased on CAN high-level protocol SAE J1939 protocolThe protocols between different devices are unified into a standard interface, thus enabling different devices to communicate with each other.ISOBUS-compatible machines can be directly connected to the control network of agricultural machinery.It can therefore be controlled by a single control terminal in the cab. It can help integrate multiple on-board systems such as GPS and precision agricultural data.

Application of CAN bus in agricultural machinery

Precision Agriculture

Precision agriculture, also known as precision farming or precision farming, is a comprehensive and integrated high-tech agricultural application system that has emerged in recent years and is specialized in field crop cultivation. Precision agriculture is supported by information technology, according to the spatial variation, positioning, timing, quantitative implementation of a set of modern farming operations and management systems, is a new type of agriculture, information technology and agricultural production comprehensive integration of CAN bus technology canRealize the collection, transmission and integration of various data on agricultural tools.In addition, the data will be analyzed, e.g. vehicle speed, working area, longitude, latitude, engine data, etc., so that the data can be used for the purpose of the analysis.To facilitate follow-up research and improvement of agricultural projects.

 Agricultural Repair and Maintenance

Agricultural machinery and agricultural equipment are used more frequently in agricultural production or harvesting time, and the environment for operation is harsh, and rarely used at other times, parts and components may be worn or functionally degraded to affect the normal use, so it is important to carry out regular repair and maintenance of agricultural machinery. can bus users canMonitor and capture the operating status and fault information of various components of agricultural machinery.In order to detect problems and carry out repairs in a timely manner.Improve processing efficiency and safety.

Meeting current and future agricultural machinery needs

In 1983, CAN bus protocol was designed and launched by Bosch, Germany. 1985, Kvaser began to specialize in the research and development of CAN technology, and has been deeply engaged in the industry for 40 years, so far, it has launched more than 100 CAN products, and Kvaser products are loved by engineers all over the world due to their reliable, convenient and durable quality.Advanced and reliable CAN hardware can help technicians optimize the application technology and facilitate the modernization of agricultural machinery.

Case Sharing

Agricultural electromechanical integration is the current focus of the modernization of agricultural machinery technology development, the Institute of Agricultural Electromechanical Integration of the Technical University of Munich, Germany is a pioneer in the field.Kvaser's products and software are used in the development of practical applications of their cutting-edge technologies.Their research projects involve tractors and other agricultural vehicles, automation of tractor implements, vehicle communication technologies (e.g., ISOBUS), self-driving agricultural vehicles and robots.

As part of the DigiMilch (Digital Dairy Project), one of the pilot field projects in Germany aimed at improving dairy farming through digital technology, the Technical University of Munich (TUM) is investigating how to achieve a precise utilization of manure. In order to obtain data on the performance of agricultural machinery in the field, the TUM is using in the projectKvaser Memorator Light HS v2Time-synchronized data is collected to analyze the performance of agricultural machinery in the field and all the information is collected into one file and exported in many different formats, and then the file is imported into MATLAB for subsequent analysis.

Samuel Brodie, a PhD student on the team, emphasized that the integration of Kvaser hardware products with MATLAB and other software tools facilitates their subsequent analysis and refinement work, which was one of the reasons why the Technical University of Munich chose Kvaser in the first place.
