Description

Technical field of expertise:

[0001] The invention relates to automated water management systems, in particular a sensor-driven urban water detection, alarm and motor control system that notifies users when the water supply starts and autonomously operates a motor to fill storage tanks, with the motor stopping when the flow ceases. Background of the invention:

[0002] In many urban and semi-urban areas, the municipal water supply is one of the most important utilities for daily life, but it is often provided at unpredictable intervals and for limited periods. This irregularity in the water supply poses significant challenges for households and businesses that rely on timely water availability for cooking, cleaning, sanitation, and other essential needs. Users often face the challenge of being vigilant in monitoring water delivery schedules, which can vary considerably and often occur without prior notice. Missing the delivery window can result in incomplete filling of water tanks, leading to water shortages that day.On the other hand, running motors during periods without water flow can lead to dry running, overheating, increased energy consumption, and ultimately damage to the pump equipment. Such inefficiencies contribute to resource waste, financial losses, and inconvenience for users.

[0003] Traditional methods of water monitoring rely on manual observation, requiring individuals to constantly check faucets or pipes to determine when water is available. While this practice may be manageable in households with predictable supply times, it becomes a significant inconvenience when water supply is irregular or occurs at unusual times. Furthermore, the lack of real-time notification systems results in water flow being turned on and off multiple times within a supply window, forcing users to frequently adjust motor controls to prevent running dry. In densely populated areas where water availability per household is already limited, such inefficiencies can further strain local water management infrastructure and exacerbate scarcity.

[0004] Over time, several automated water management solutions have been investigated to address these challenges. Some systems use timers to regulate motor operating times, while others employ simple float-valve-based mechanisms to detect water levels in storage tanks. However, these methods often fail to address the core problem of irregular urban water supply schemes, focusing more on preventing tank overflows than ensuring timely water collection. Furthermore, time-controlled systems assume a fixed supply schedule, which is rarely the case in most regions, and float-valve-based systems only regulate motor activity once water is already flowing into the tanks, thus providing users with no real-time warning of the start of water supply.

[0005] Advances in sensor technology and microcontroller-based automation offer the opportunity to develop a more reliable and responsive solution. Water flow sensors capable of detecting even minute changes in flow rate, combined with compact and cost-effective microcontrollers, can provide an integrated platform for monitoring, alarming, and controlling water flow operations. Utilizing these components makes it possible to design a system that not only informs users about water availability but also autonomously operates the motor to efficiently fill tanks and prevent running dry when the supply is interrupted.

[0006] The present invention addresses this need by providing a fully automated system for water detection, alarm notification, and motor control that operates in real time, ensuring that households and commercial establishments can maximize water collection without unnecessary manual intervention. The integration of a buzzer system provides immediate user alerts, while the motor control function ensures that storage tanks are filled promptly and energy consumption is optimized. This approach tackles the long-standing problem of unpredictable urban water schemes while promoting improved water management, energy savings, and user-friendliness. Summary of the invention:

[0007] The present invention introduces an automated urban water detection and management system designed to address the challenges associated with unpredictable water supply plans. It integrates sensor technology, alarm mechanisms, and intelligent motor control to ensure efficient use of available water resources while minimizing human intervention. The system is particularly suitable for residential and commercial areas where continuous monitoring of urban pipelines is required to ensure timely water collection.

[0008] At the heart of the invention is a water flow sensor strategically placed within the pipeline to detect the start of the water supply with high accuracy. Once water is detected, the sensor sends a signal to a microcontroller, such as the Arduino Atmega328p, which serves as the system's processing unit. The microcontroller interprets the input data and immediately triggers an alarm, audibly signaling to users that water is available. This real-time warning mechanism allows users to react quickly to the availability of the water supply without having to constantly check manually.

[0009] In addition to providing warnings, the system is designed to automatically control the water pump. Upon receiving a sensor signal, the microcontroller activates a relay module that powers the motor and initiates the filling of the storage tank. The motor continues to run as long as the water flow is maintained to ensure maximum utilization of the available supply. If the water flow slows significantly or stops completely, the microcontroller immediately deactivates the relay, shutting off the motor to prevent dry running, reduce energy consumption, and extend the motor's service life.

[0010] The system can also include an LCD display to show users real-time operating status, such as water detection, motor activity, and system readiness. All components are powered by a 9-12V DC power supply, ensuring compatibility with standard household electrical systems and providing reliable performance with minimal energy consumption.

[0011] This invention represents a significant improvement over traditional water management systems by addressing the fundamental problem of unpredictable supply schedules. Unlike time-controlled systems that operate according to fixed schedules or floating systems that only manage overflow control, the present invention ensures that water collection begins immediately upon detection of supply, regardless of the schedule. The combination of real-time detection, audible alarm, and automated motor control provides a seamless and efficient solution for residential and commercial facilities.

[0012] Furthermore, the system is designed to be compact, cost-effective, and easily integrated into existing water supply infrastructures, requiring only minimal modifications. Its automation features not only offer convenience but also contribute to resource conservation by preventing unnecessary motor operation and reducing energy consumption. Over time, this leads to savings in operating costs, improved water availability, and greater user satisfaction.

[0013] Through its innovative design, the present invention eliminates the need for manual water monitoring, addresses the inefficiencies of existing solutions, and provides a robust method for managing urban water supplies in environments where reliability and timely access are critical. Brief description of the drawing Fig.shows a block diagram of the system according to the invention. Detailed description of the invention

[0014] The present invention, entitled "Urban Water and Alarm System as well as Automatic Motor Control for Switching On and Off," offers a fully automated approach to managing the water supply in areas where the availability of municipal water is irregular and unpredictable. It integrates advanced sensor technology, microcontroller-based automation, and real-time notification mechanisms to detect water flow, notify users, and automatically operate the motor to fill storage tanks. This section provides a comprehensive description of the invention, its functional components, its operation, its integration into existing infrastructures, and its potential applications. Introduction to the system

[0015] Water scarcity, irregular municipal water supply schedules, and human reliance on manual monitoring have long posed challenges to efficient water management in households and businesses. In several regions, municipal water supplies are available only for limited and irregular periods, often without prior notice, making it difficult for users to determine the precise time of availability. Missing this brief window results in insufficient water collection, while excessive reliance on manual monitoring requires users to remain vigilant for extended periods, which is impractical and inefficient.

[0016] The present invention addresses these concerns by developing an automated water management solution that begins operating immediately upon detection of water flow and stops immediately when the supply decreases or ceases. An alarm system ensures that users are notified immediately, while the automated motor control efficiently fills the water tanks without requiring manual intervention. This combined functionality not only improves ease of use but also optimizes energy consumption, minimizes wear and tear on the pump equipment, and prevents resource waste. System architecture and components

[0017] The invention is based on a series of key components, both electronic and electromechanical, that work together to detect water flow, alert users, and control motor operations. The main components include a water flow sensor, an Arduino Atmega328p microcontroller, a relay module, a DC water motor, a buzzer, an LCD display (optional), and a power supply unit. Each of these components has a specific role, and their integration ensures the smooth operation of the system.

[0018] The water flow sensor is the first point of interaction with the municipal water supply. It is strategically positioned within the pipeline to detect the presence and flow rate of water. When water begins to flow, the sensor generates electrical signals proportional to the water's velocity. These signals are transmitted to the microcontroller, which processes them in real time.

[0019] The Arduino Atmega328p microcontroller acts as the system's control unit. It receives input signals from the flow sensor and interprets them to determine whether water is flowing. Once water is detected, the microcontroller performs two important tasks simultaneously. First, it activates the buzzer to emit an audible tone, informing users that water is available. Second, it activates the relay module, which in turn powers the motor to start the water pump.

[0020] The relay module acts as an electronically operated switch, allowing the microcontroller to control the motor without a direct electrical connection, thus protecting sensitive electronic circuits from voltage spikes. Once the relay is activated, it establishes the necessary connection to the motor's power supply, enabling it to begin filling the storage tank.

[0021] The DC water motor acts as a pumping mechanism, drawing water from the municipal pipeline into the designated storage tank. Its DC operation ensures energy efficiency, reduced noise, and reliable performance, particularly in residential environments where operational reliability is paramount. The motor remains active as long as the sensor detects water flow.

[0022] The buzzer is an essential warning mechanism that emits an audible signal when water starts flowing. The purpose of this feature is to ensure users are aware of water availability, even if they are not actively monitoring the system. This alarm mechanism is particularly useful during night shifts or early morning hours when continuous manual monitoring would be impractical.

[0023] An LCD display can be integrated to provide users with real-time feedback on the system's operating status. The display can show whether water is flowing, the motor is active, or the system is in standby mode. Although optional, this feature adds a level of user awareness and transparency to the system's operation.

[0024] The entire system is powered by a 9-12V DC adapter, which converts standard alternating current (AC) from the wall socket into direct current. This ensures a stable and efficient power supply for the microcontroller, relay, motor, and auxiliary components. Operational methodology

[0025] The system's operation begins with the continuous monitoring of the pipeline for water flow. Under normal conditions, when no water is present, the flow sensor remains inactive, and the system keeps the motor off to conserve energy. As soon as water flows from the municipal water network, the sensor detects the movement and generates electrical pulses corresponding to the flow rate. These pulses are transmitted to the microcontroller, which interprets them to confirm the presence of water.

[0026] Upon detection, the microcontroller immediately activates the buzzer, which generates an audible signal informing users that water is available. Simultaneously, the relay module is activated, powering the DC water pump motor, which then begins pumping water into the tank. This automated sequence eliminates the need for users to manually start the motor or continuously monitor the water supply.

[0027] The system remains in this state as long as water flow is detected. During this time, the microcontroller continuously receives data from the sensor to ensure that motor activity is maintained only when necessary. If the water flow decreases significantly or stops completely, the sensor's output signals reflect this change, prompting the microcontroller to deactivate the relay. Consequently, the motor is switched off to prevent dry running and avoid unnecessary power consumption.

[0028] This real-time response mechanism ensures maximum efficiency in water collection while protecting the motor from mechanical stress and overheating. Additionally, the buzzer serves as an important feedback system, allowing users to check water availability and monitor system performance without requiring constant supervision. Integration with existing infrastructure

[0029] One of the main advantages of this invention lies in its easy integration into existing residential and water supply systems. The sensor can be installed directly in the supply line without requiring extensive modifications. The microcontroller, relay, and buzzer can be housed in a compact control unit that can be wall-mounted near the motor or storage tank. The DC motor, already commonly used in many homes, can be connected to the system with minimal adjustments, making installation simple and cost-effective.

[0030] The optional LCD display can be positioned in a convenient location to provide real-time operational feedback. To improve user convenience, future versions of the system could integrate wireless modules to send notifications to smartphones or other connected devices, extending its functionality to remote monitoring. Technical considerations and advantages

[0031] The invention was developed to ensure robustness, energy efficiency, and operational reliability. The use of a microcontroller enables precise motor control, while the relay module provides electrical isolation to prevent damage from voltage fluctuations. The system's low power consumption ensures minimal operating costs, and its compact design allows for use in various environments.

[0032] By automating the detection and pumping process, the invention eliminates delays in water collection, which is particularly important in areas with short supply times. Furthermore, it prevents common problems associated with manual operation, such as dry running and motor overheating, thereby reducing maintenance costs and extending the service life of the equipment.
