PLC Control System Integration for a Leading Poultry Farm’s Duck Breeding Base

A leading domestic poultry enterprise commissioned Qingdao Xiaoyang Electric to integrate a PLC control system for its large-scale duck breeding base. Our team developed a customized multi-channel centralized control cabinet based on the breeding process requirements, enabling full-process automated monitoring and management of duck breeding operations.

Project Background

Duck breeding has strict requirements for environmental parameters (temperature, humidity, ventilation, lighting, drinking water, feeding, etc.). Traditional manual control methods suffer from slow response, large errors, and high labor costs. This enterprise operates a large-scale duck breeding base and urgently needed a stable and reliable PLC automation control system for precise regulation and remote monitoring of the duck house environment.

Customer Pain Points

Multi-channel control requirements: Each duck house involves dozens of ventilation, lighting, feeding, and drinking control circuits. Traditional relay control is complex and has high failure rates.
High environmental stability requirements: Egg production rate is sensitive to temperature and humidity changes, requiring 24/7 stable control.
Scalability needs: The breeding base is built in phases, requiring the control system to support future expansion and remote upgrades.
Harsh on-site environment: High dust and ammonia concentrations in duck houses demand high protection ratings and reliability for electrical equipment.

Xiaoyang Solution

Addressing the specific needs of duck breeding scenarios, Xiaoyang Electric adopted a “PLC centralized control + distributed IO” architecture and developed a customized main control cabinet with the following features:

Fully automatic environmental control: Automatically adjusts ventilation and heating/cooling equipment based on temperature and humidity sensor data to maintain a constant duck house environment.
Intelligent lighting management: Automatically adjusts lighting duration and intensity according to the duck growth cycle to improve egg production rates.
Timed feeding and drinking: Precisely controls feeding lines and drinking systems on schedule to reduce feed waste.
Abnormal alarm protection: Automatic alarms for over-temperature, equipment failure, power outages, and other anomalies to ensure breeding safety.
Remote monitoring interface: Reserved communication interface supports future integration with IoT platforms for mobile APP remote monitoring.

Core Configuration
