Description

Technical Field

[0001] This utility model relates to the field of water leakage monitoring technology, specifically a multimodal intelligent power outage and water leakage monitoring and alarm device. Background Technology

[0002] In modern society, a safe and stable supply of water and electricity is crucial in all kinds of settings, whether it's industrial production workshops, commercial office buildings, or residential homes. However, traditional power outage and water leakage monitoring and alarm devices have many limitations.

[0003] In industrial sectors, such as electronic chip manufacturing plants, the production environment is extremely sensitive to humidity and water leakage. If a leak occurs and is not detected in time, it can lead to short circuits and damage to expensive production equipment, affecting chip yield and causing significant economic losses. However, traditional water leakage sensors often employ simple electrode designs, which are ineffective at detecting non-conductive liquids commonly used in chip manufacturing, such as deionized water, and are prone to missing potential leakage risks. Furthermore, in complex industrial electromagnetic environments, these sensors may frequently trigger false alarms due to interference, disrupting normal production processes.

[0004] In commercial office spaces, data centers house a large number of servers and electronic devices, and a continuous and stable power supply is crucial to ensuring the normal operation of businesses. Water damage and electrical leakage can not only cause server downtime, leading to data loss and business interruption, but may also trigger secondary disasters such as fires. However, existing power outage monitoring devices often only activate after severe faults such as short circuits have occurred, lacking the ability to effectively monitor and warn of early-stage hazards such as water damage and electrical leakage, and thus failing to cut off power in time to prevent the accident from escalating.

[0005] In residential homes, the widespread adoption of smart home devices presents new challenges to household electrical safety. Outdated monitoring and alarm systems are limited in function, only providing local audible and visual alarms. When residents are away, they cannot promptly detect any abnormalities in their home's water or electricity systems. For example, a burst water pipe could flood floors, furniture, and even leak into downstairs neighbors' homes, potentially causing disputes. Furthermore, fire hazards caused by electrical wiring faults, if not detected and addressed promptly, could have disastrous consequences.

[0006] In summary, the market urgently needs a multimodal intelligent power outage and water leakage monitoring and alarm device that can overcome the aforementioned problems and possesses high-precision detection, strong environmental adaptability, and intelligent remote monitoring capabilities to ensure water and electricity safety in various locations and reduce potential risks and losses. Currently, power outage and water leakage monitoring and alarm devices on the market typically rely on a single sensor, only achieving basic power outage or water leakage detection. Their detection accuracy, environmental adaptability, and intelligence level are relatively low, failing to meet the needs of complex application scenarios. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a multimodal intelligent power failure and water leakage monitoring and alarm device, which improves detection accuracy and intelligence level through the fusion of multiple sensors and the integration of Internet of Things, and adapts to a wider range of scenario needs.

[0025] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0026] like Figure 1 As shown, this utility model proposes a multimodal intelligent power failure and water leakage monitoring and alarm device, including a control module 1, a water leakage sensor 2, an acoustic sensor 3, a pressure sensor 4, an Internet of Things (IoT) module 5, an alarm module 6, a power supply module 7, a power monitoring and protection module 8, and a backup power supply 9. The power supply module 7 and the backup power supply 9 are electrically connected to the control module 1, the water leakage sensor 2, the acoustic sensor 3, the pressure sensor 4, the IoT module 5, the alarm module 6, and the power monitoring and protection module 8. The control module 1 is electrically connected to the water leakage sensor 2, the acoustic sensor 3, the pressure sensor 4, the IoT module 5, the alarm module 6, and the power monitoring and protection module 8. The input terminal of the power monitoring and protection module 8 is electrically connected to the power supply module 7.

[0027] The control module 1 is a microcontroller, and its model is not specifically limited, such as the MSP430 series or STM32 series microcontrollers.

[0028] The water leakage sensor 2, model RS-SJ-N01R01-2, employs AC detection technology, effectively avoiding the problem of decreased sensitivity due to oxidation of the electrodes after prolonged immersion in water. It offers optional 485 output and switch dry contact output. The 485 output is a standard ModBus-RTU with a maximum communication distance of 2000 meters.

[0029] The acoustic sensor 3, model TDK ICS-40720, consumes low power during operation, making it suitable for battery-powered devices such as wireless microphones and portable audio recorders. This extends the device's battery life and reduces the frequency of battery replacements. Furthermore, it directly outputs digital signals, facilitating connection to digital signal processing systems without requiring additional analog-to-digital conversion circuitry, simplifying system design and improving the accuracy and stability of signal transmission.

[0030] The IoT module 5 is a Wi-Fi module, a 4G / 5G module, or a LoRa module, used for wirelessly transmitting on-site detection sensor signals or alarm signals to a remote smart terminal.

[0031] The alarm module 6 is an audible and visual alarm circuit, wherein the visual alarm includes two LEDs indicating water leakage and power outage alarms respectively, such as... Figure 3 As shown, S is a buzzer alarm, and D1 and D2 are LEDs indicating water leakage and power failure, respectively, with different colors for the LEDs.

[0032] like Figure 2 As shown, the power monitoring and protection module 8 includes a current detection circuit, a signal conditioning circuit, and a tripping drive circuit connected in sequence. The signal conditioning circuit includes a compensation circuit with a capacitor and resistor in parallel, and an energy storage circuit based on a rectifier bridge and an energy storage capacitor. The tripping drive circuit includes a voltage detection chip and a MOSFET-based magnetic tripping circuit. When the signal detected by the current detection circuit is compensated by the compensation circuit, then rectified and filtered, and then the voltage is detected by the voltage detection chip, if the power line experiences water immersion and leakage, the voltage detection signal will be abnormal. The voltage detection chip will then output a control signal to the MOSFET, which will drive the trip unit to perform a power-off protection action. Simultaneously, the abnormal signal detected by the voltage detection chip will be output to the microcontroller. The voltage detection chip is model D55126, a high-performance CMOS leakage current protector. Internally, the chip includes a regulated power supply, an amplifier circuit, a comparator circuit, a delay circuit, a counter circuit, a tripping control circuit, and a tripping drive circuit. The chip's peripheral components include trip coils, varistors, Zener diodes, diodes, resistors, and capacitors, and it is packaged in an SOP8 package.

[0033] Backup power supply 9 is a lithium battery, connected in parallel with power module 7 to supply power to the system. The power module is a DC switching power supply, used to convert the AC voltage of the power line into a low-voltage DC voltage to power the various modules of the system. When the power module fails, the lithium battery automatically takes over the power supply, similar to the battery power supply in a laptop computer.

[0034] This invention integrates multiple sensors, such as an AC leak sensor that uses AC detection technology, effectively overcoming the shortcomings of traditional electrode sensors in detecting non-conductive liquids. It can accurately detect various liquid leaks, reducing the risk of missed detections. An acoustic sensor can assist in detecting the sound characteristics of leaks, and a pressure sensor can be installed in water storage or transport pipes and containers. When a leak occurs, the internal pressure changes, and the pressure sensor can monitor these changes in real time. Based on a preset pressure threshold, it determines whether a leak exists, further improving the accuracy and reliability of leak detection and providing strong support for the timely detection of potential water and electricity hazards.

[0035] With the help of IoT modules (Wi-Fi, 4G / 5G, or LoRa modules), on-site sensor signals and alarm signals can be transmitted to remote smart terminals in real time. This allows users to keep track of the water and electricity status of the monitored area from anywhere. For example, enterprise managers can remotely monitor the operational safety of data center equipment, and residents can check the water and electricity status of their homes at any time, realizing intelligent management and greatly improving the response speed and handling efficiency of water and electricity accidents.

[0036] The power monitoring and protection module significantly improves electrical safety. When water immersion and leakage are detected in the power line, the current detection circuit, signal conditioning circuit, and tripping drive circuit (including the voltage detection chip D55126 and the MOSFET magnetic tripping circuit) work together to quickly cut off the power supply and avoid serious consequences such as equipment damage caused by water immersion and leakage.

[0037] The design of the backup power supply (lithium battery) connected in parallel with the power module ensures the continuity of system power supply. When the power module malfunctions, the lithium battery can automatically take over the power supply to maintain the normal operation of the device, avoid the failure of monitoring and alarm functions due to short power outages, ensure uninterrupted hydropower monitoring, and provide continuous support for stable equipment operation and safety assurance.

[0038] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
