ISOBUS, short for ISO 11783 '', is an open standard of international communication used by the agricultural and forestry industry. Certified by the Agricultural Industry Electronics Foundation (AEF), it is officially defined as tractors and machinery for agriculture and forestry - Serial control and communications information network.

It standardizes the communication between different implements, allowing the exchange of information between different brands and models of tractors, implements, and controllers.

What are The Benefits of ISOBUS?

1. Ensuring the compatibility between tractors and implements regardless of brand and model

With the rapid development of precision agriculture, precise control of each implement has become essential in farming operation. Currently, all precision farming and agriculture machinery manufacturers are moving toward a common goal of compatibility, and ISOBUS is used to achieve this goal by making tractors and implements fully compatible, regardless of brand and model.

Before the ISOBUS standard was proposed, each manufacturer used its own communication language for agricultural machinery. Farmer could only use specific display and proprietary control system to operate implements. If they got a new tractor or implement, the display/controller may not be available due to incompatibility, which increases the cost of agricultural operations.

2. Improved operational accuracy for precision agriculture

By using the ISOBUS standard, the information transfer between the system and the software is smooth. The ISOBUS ensures fast and noiseless communication and improves the accuracy of the implement work.

At the same time, operator can see all information about their tractor and implements on a single display. The high level of information integration helps farmer to make better decisions for precision agriculture, thus increasing productivity.

3. Simplified installation and operation

When ISOBUS is not used, a wiring structure for each sensor and a display for each implement are required in machinery. Using the same tractor in different operating situations results in a cab full of interfaces, which can hinder operation and complicate installation.

The use of ISOBUS eliminates redundant displays and unnecessary connection cables, leaving only one display to connect the tractor and its implements, making the installation and operation of farm machinery simple and efficient.

How Does ISOBUS Work?

1. UT/VT, Virtual Terminal.

Provides an interactive interface between the operator and the implement, and the display shows current working status of the implement;

2. TC-BAS, Task Controller basic (totals)

Allows the import of planned tasks into the agricultural management system and the export of operation records to assist in planning agricultural operations. Allows the aggregation of total values in working conditions.(e.g., total volume spent on sprayer operations, total mass of fertilizer applied by spreader.)

3. TC-SC, Task Controller Section Control

Provides and records information on the operation of the farm machinery. Section control based on geographic location and desired level of overlap; Enabling control of the opening and closing of the seeding/fertilizer application ports within the section on the implement.

4. TECU, Basic Tractor ECU

Monitoring and output of the working status of the tractor, providing and recording information of the tractor operation.

5. TC-GEO, Task Controller geo-based (variables)

Control the opening rate of each section based on geographic locations and variable rate operation record information..Establish a speed control model based on the speed of the vehicle, the height of the seeding opening/fertilization opening in the section from the ground, and the agronomic requirements.

ISOBUS Applied to FJDynamics Auto Steer Kit

FJDynamics Auto Steer Kit for the tractor is a high-accuracy GPS auto-guidance and steering system. With GNSS & RTK technology, it controls the tractor's driving direction with a precision of 2.5cm. The tractor's movement is observed and controlled through the display control terminal.

This automatic steering kit adopts the ISOBUS communication protocol. It can be used for any brand and model of tractors and farm implements, and can greatly reduce operating costs while improve production efficiency.
