Automatic Weighing and Feeding Equipment PLC Data Acquisition Solution

Published: 2026-05-27 17:02:28

In large-scale pig farming, the importance of precise feed management is increasingly recognized. A smart pig farm has recently deployed a new set of automatic weighing and feeding equipment, using a Schneider PLC as the core controller. The system is connected to multiple weighing instruments and feeding carts. By reading data from each weighing instrument, the PLC automatically controls the position of the feeding carts and the opening and closing of valves. This solution plays a key role in reducing costs, improving efficiency, and minimizing labor requirements on the farm.

 

The data generated by this system now needs to be integrated into the existing smart farming IoT platform (which uses MQTT as its uplink protocol). WideIOT provides an efficient and reliable IoT solution for this purpose. By deploying an industrial IoT gateway, the system can connect to the Schneider PLC, collect real-time data such as weight readings, feeding cart travel distance, and valve status, and convert the data into standard MQTT protocol. The data is then transmitted via 4G to the smart farming IoT platform. This enables remote monitoring, alerts, management, control, and data analysis of the feeding process, helping to improve management efficiency and overall productivity.

Key Features

1. Real-time data collection of weighing values, single/cumulative feed amounts, feeding cart travel distance, equipment start/stop status, valve open/close status, emergency stop signals, fault reset status, and more. These data points provide the foundation for system control and data analysis.

 

2. A visual monitoring dashboard is created on the platform. Managers can view equipment operation status, feeding progress, and feeding data for each pen or barn in real time via PC or mobile devices.

 

3. Abnormal data is automatically detected and alerts are triggered. Notifications can be sent via WeChat, SMS, or email. The system also supports remote control of the PLC, allowing operators to start/stop the feeding cart and open/close valves remotely.

 

4. Comprehensive analysis of feeding and equipment operation data is supported. Key metrics such as feed consumption and equipment alert rates can be analyzed on a daily, weekly, monthly, or yearly basis, helping businesses make informed, data-driven decisions to reduce costs and improve efficiency.
