ISOBUS Scale ECU

ISOBUS Compatible Weighing ECU (Electronic Control Unit)

This detailed description is about the weighing ECU manufactured by Intercomp, designed according to the ISOBUS standard, which ensures the integration and efficient operation of precision agricultural weighing systems. This unit is a crucial component for the standardized digital transmission of data from vehicle-mounted scales, tanks, and other weighing applications to the tractor or agricultural machine's onboard display.

The ISOBUS ECU enables seamless communication of weighing data with the tractor's ISOBUS terminal, ensuring a standardized user interface and simple data management for optimizing farming operations.

Key Features and Advantages

The purpose of the ISOBUS ECU is to make existing or new weighing systems (e.g.: tanks, seed tanks, feed mixers) compatible with the digital ecosystem of modern agricultural machinery.

• ISOBUS Standard Compatibility: Fully compliant with ISOBUS (ISO 11783) specifications, enabling communication with any ISOBUS compatible terminal.
• Data Consistency: Unifies weight data originating from various sensors, ensuring accurate and reliable measurement during agricultural operations.
• Simplified Integration: „Plug-and-play” connection style to existing Intercomp load cells and displays, minimizing installation time and cabling complexity.
• Robust Construction: Designed to withstand harsh agricultural environmental conditions, including vibration, extreme temperatures, and moisture.
• Diagnostic Capabilities: Built-in self-diagnostics functions assist with rapid troubleshooting and maintaining system integrity.

Technical Specifications

The precise and reliable operation of the ISOBUS ECU is guaranteed by the following technical parameters:

Application Areas

This ECU is the ideal choice for all agricultural measuring tasks where digital data processing and standardized communication between machines are essential:

1. Tanks and Seeders: Accurate measurement of fill level and tracking of dispensed quantity directly on the tractor display.
2. TMR Feed Mixers: Real-time checking and recording of feed ingredient weights during the mixing process.
3. Bulk Goods Measurement: Measurement of the load in silos, tanks, or trailers, where weight data is processed immediately.
4. Vehicle Weighing System Integration: Enables the reading of portable or fixed axle load scale data (e.g., LS-WIM systems) via the ISOBUS network.

Depth of Software Integration

The use of the ISOBUS standard is not just about hardware connectivity; the software layer is also crucial. The ECU functions as an intelligent data converter that processes, calibrates, and then standardizes raw analog signals. PGN (Parameter Group Number) sends them in the form of messages via the ISOBUS bus.

This approach ensures that measurement data (e.g.: net weight, gross weight, unit of measure, status) can be displayed immediately on the user's preferred terminal, regardless of its manufacturer. The system supports ISOBUS standard auxiliary control functions (ACF) and task controller (TC), if required by the farm management software.

Installation and Maintenance

The Intercomp ISOBUS ECU is designed so that installation requires minimal expertise. The robust housing and standardized connectors ensure quick and reliable fastening to the machine. System maintenance is primarily limited to regular calibration checks, which can be performed using the included software or a compatible virtual terminal. Digital communication minimizes the risk of signal loss or interference over time, which is a common problem with traditional wired displays.

This ISOBUS ECU is the pinnacle of Intercomp's weighing technology, placing weighing data into the digital future of precision agriculture.
