The essay "Microcontroller-Based Constant Pressure Water Supply System Design" discusses the implementation of a water supply system in a university campus to address the challenges of high energy consumption, low reliability, water wastage, and incomplete pipeline systems in the existing water supply system. The proposed solution combines constant pressure water supply and water pump lifting with the use of frequency converters, soft starters, microcontrollers, leak compensators, pressure sensors, and liquid level sensors to maintain the pressure in the pipeline within the appropriate range. By controlling the speed of the water pump through the frequency converter based on the pressure in the pipeline, the system can ensure sufficient pressure and reduced energy consumption, especially in high-rise buildings where low pressure and high energy consumption are common issues. The efficiency of the system is further enhanced by the relationship between the power consumption of the water pump and the cube of the motor speed, demonstrating significant energy savings compared to conventional water supply methods. Moreover, the integration of a programmable controller enables variable frequency control of the main pump, soft start of the auxiliary pump, and provides short circuit and overcurrent protection functions, ensuring stable and reliable operation while extending the lifespan of the motor. The use of a microcontroller also allows for automated control of the system, making it more efficient and reducing the need for manual intervention. Overall, the implementation of the proposed constant pressure variable frequency water supply system with microcontroller technology offers a more energy-efficient, reliable, and sustainable solution for water supply in university campuses.
