Water security and water resource management have become key factors influencing social and economic development. In many urban and rural areas of Shaanxi Province, traditional manual methods are still used in monitoring drilling and hydrological stations. These outdated practices not only pose safety risks to personnel but also result in inaccurate data collection, lack of real-time updates, and inefficiencies. With the rise of the Internet of Things (IoT) and information technology, modernization of urban and rural water supply systems has become essential. By implementing automation, these systems can achieve scientific management, ensure safe and reliable operation, protect water pumps, reduce energy consumption, save water resources, and lower operational costs. Advanced technologies such as software image recognition, wireless GPRS communication, mobile telecommunications, and IoT are integrated to enable remote centralized monitoring and management, ultimately achieving modernized water supply systems.
On-site requirements and system block diagram
During the well-drilling process in urban and rural areas, it is crucial to monitor deep well water levels and temperatures, as well as the real-time water levels in each reservoir. In automated water supply operations, the power and output of water pumps must be tested and compared, while data from electromagnetic flow meters, pipeline pressure, and reservoir levels are monitored centrally. This data is then sent to a centralized data management center. The system enables data acquisition, display, graphing, audio-visual alarms, automatic pump control, and alert notifications for on-duty staff when water levels exceed limits.

Introduction
In Weinan City, Shaanxi Province, all water supply plants and rural drilling teams have been integrated into a unified monitoring system. The monitoring points are spread over a wide area with a large number of units. Currently, villages, counties, and related water supply units are gradually adopting automated monitoring, transmission, and alarm systems. Each unit performs automated water source management, and the collected data is transmitted through the Internet to the central monitoring station for spot checks. Each unit is equipped with deep well level and temperature transmitters, with 2–3 reservoirs around each well. One level transmitter is installed in each reservoir, along with an electromagnetic flow meter and a pressure sensor at each water pump outlet (typically three or more pumps). All sensors transmit signals to a 485 acquisition module or a wired gateway, and the system is designed using PLC technology and a human-machine interface. Dynamic engineering screens are configured for automatic water supply, water level alarms, report generation, and inquiries. The user interface is intuitive, secure, and reliable, allowing control of GPRS DTU modules and relay modules to make pump decisions and issue alarms.

This system automatically monitors pump output and water levels, and includes an emergency manual control system to ensure continuous water supply for residents. It reduces the workload of on-duty personnel and improves overall efficiency. Additionally, the control center and relevant departments can analyze data and make informed decisions to ensure stable and high-quality water supply that meets demand.
