They primarily supply fire trucks with water from the municipal or outdoor fire water supply network for firefighting. They can also be directly connected to hoses or nozzles to discharge water, making them a crucial firefighting facility. However, their widespread distribution, outdoor installation, and ease of use make them vulnerable to vandalism and water theft. Some hydrants suffer from problems such as lack of water or insufficient water pressure. For example, vehicle collisions can knock down fire hydrants, leading to prolonged water loss. Illegal use of fire hydrant water for temporary construction, landscaping, and vehicle washing is widespread.

[0039] See also Figures 1 to 9 This embodiment provides an integrated smart fire hydrant, comprising a hydrant body. The hydrant body has a conventional fire hydrant structure. Specifically, the hydrant body has a water outlet port, which connects to a connector on one end of a hose. The other end of the hose connects to a water nozzle. The water nozzle is used to spray water or foam, and different types of nozzles are selected based on firefighting needs. It is typically equipped with a valve that is manually opened to control the water flow and flow rate. Furthermore, the hydrant body has a fixing device, located below the hydrant body and typically buried underground, to secure the fire hydrant in place and prevent movement. The hydrant body is equipped with an IoT main control module, a communication module, a detection module, and a power supply module. These modules are housed in a housing integrally formed with the hydrant body, resulting in a higher level of integration, lower costs, enhanced reliability, and simplified installation and maintenance. The detection module includes a water pressure sensor, a water flow sensor, and a tilt sensor; the detection end of the water pressure sensor is located within the hydrant body. The IoT main control module transmits information to a higher-level management platform via the communication module.

[0040] The power supply module can be AC power or a battery. When connected to AC power, it needs to be equipped with a power supply conversion device. Since the power consumption of the electrical devices used is low and considering the power supply cost, a battery can be used for power supply, such as a 3.6V lithium-ion battery, which greatly reduces the cost.

[0041] The water flow detection pin (PC1) of the IoT main control module is connected to the signal output end of the water flow sensor, and the detection end of the water flow sensor is arranged inside the plug body. The water pressure detection pin (PA4) of the IoT main control module is connected to the signal output end of the water pressure sensor; the tilt detection pins (PB8 / PB9) of the IoT main control module are connected to the signal output end of the tilt sensor; the power supply pins (VDD_1 / VDD_2 / VDD_3 / VDD_4) of the IoT main control module are electrically connected to the output end of the power supply module; and the communication pins of the IoT main control module are connected to the communication module.

[0042] The model of the water pressure sensor can be MD-S271FC or MD-S273, and its detection process is as follows: 1. Pressure sensor sensitivity: The water pressure sensor usually contains a thin film or flexible sheet, which is subjected to the force of liquid or gas pressure. For example, when the water pressure increases, the film will be squeezed or deformed. 2. Diaphragm deformation leads to electrical signal generation: When the film is deformed due to pressure changes, its electrical characteristics such as resistance, capacitance or inductance will also change accordingly. These changes can be detected and measured by the circuit inside the sensor. 3. Electrical signal conversion: The measured change in electrical characteristics will be converted into an electrical signal corresponding to the pressure change by the circuit inside the sensor. Common conversion methods include bridge, capacitance change measurement, piezoresistive, etc. 4. Signal processing and output: The converted electrical signal is transmitted to the Internet of Things main control module, and is processed and analyzed by the Internet of Things main control module to obtain the water pressure value. By monitoring the water pressure in the fire hydrant, we ensure that the water pressure is within the standard range, detect water pressure anomalies in time and perform maintenance to avoid poor fire extinguishing effects due to insufficient water pressure, or the water gun cannot be used normally due to excessive water pressure.

[0043] The water flow sensor senses water flow and outputs pulse signals, current, voltage, and other signals that are linearly proportional to the water flow, enabling water control and flow calculation. The water flow sensor detects changes in water flow and transmits the detected signals to the IoT master control module. The IoT master control module analyzes and converts the signals to generate water flow data, which is then transmitted to the upper management platform via the communication module.

[0044] The tilt sensor triggers a signal by detecting the object's tilt angle. The tilt sensor contains a freely movable mass, typically a rolling ball, with a conductive plate underneath. When the sensor is fully upright, the ball falls to the bottom of the sensor, contacts the electrical connection path, and closes the electrical connection between the two terminal terminals, allowing current to flow. However, when the sensor is tilted, the ball does not fall to the bottom and close the conductive path, resulting in an open circuit and no current flow. Specifically, a fire hydrant's tilt sensor is designed to immediately issue an alarm signal when the hydrant is impacted or tilted beyond a certain angle. The tilt sensor is placed on the fire hydrant and remains vertical along with the hydrant under normal conditions. When the hydrant tilts, it tilts the tilt sensor, generating an electrical signal that is transmitted to the IoT main control module. The IoT main control module analyzes the signal to determine the tilt angle and transmits the alarm information to the higher-level management platform via the communication module, notifying emergency personnel to respond quickly and arrive at the scene to verify the situation. This effectively improves the management efficiency and safety of fire hydrants and reduces safety hazards caused by damage or theft of fire hydrants. The tilt sensor model can be T60404-E4626-X121, BWK210, or BWM426. Preferably, the tilt sensor can use the ADXL345 three-axis chip. The ADXL345 is a small, thin, low-power three-axis accelerometer that can measure accelerations up to ±16g with high resolution (13 bits).

[0045] The IoT master control module can use an MCU microcontroller, specifically the STM32L151RCT6. The communication module can use a communication chip, specifically the M5313, MN316, BG95M2LA-64-SGNS, etc. It should be noted that the communication module uses NB-IoT communication mode for communication.

[0046] The Internet of Things main control module monitors the water flow sensor in real time, and periodically monitors the working parameters of the tilt sensor and the water pressure sensor. When the working parameters of the relevant sensors exceed the preset threshold, the device actively reports the alarm information to the upper management platform. The upper management platform is an intelligent fire hydrant comprehensive management platform, which is deployed in a cloud platform manner. The platform includes a PC-side management platform, an APP and a WeChat public account. Among them, the functions of the PC-side management platform include home page, user management, device management, alarm query, work order management, report center, digital large screen and other functional modules. The data reported by the remote Internet of Things monitoring module is comprehensively summarized, displayed and managed through the PC-side management platform, and the relevant parameters of the equipment can be remotely set through the management platform. The WeChat public account platform includes functional modules such as device management, alarm query, map display, work order management and mine. The device status of the remote Internet of Things monitoring module can be viewed and alarm queries can be queried through the mobile phone. At the same time, the device registration during the initial installation of the device can be realized through the WeChat public account.

[0047] This new integrated intelligent fire hydrant includes a hydrant body, and the outside of the hydrant body is provided with an Internet of Things main control module, a communication module, a detection module and a power supply module. The detection module includes a water pressure sensor, a water flow sensor and a tilt sensor. By integrating the Internet of Things main control module, the water flow sensor and the water pressure sensor on the fire hydrant body, and then matching the corresponding upper management platform, it is possible to simultaneously monitor the water flow, water pressure and tilt angle of the fire hydrant, and cooperate with the upper management platform for overall monitoring.

[0048] In some embodiments, a reverse circuit is further included, wherein the water flow sensor is connected to the first interrupt GPIO pin (PB10) of the IoT main control module via the reverse circuit. When the water flow sensor detects an abnormal water flow at a fire hydrant, it transmits an interrupt signal to the IoT main control module via the reverse circuit. Upon receiving the interrupt signal, the IoT main control module pauses the currently executing program, jumps to the water flow abnormality program, and promptly uploads the fire hydrant water flow data to the upper management platform, thereby improving feedback speed, facilitating timely response by maintenance personnel, and reducing water resource waste.

[0049] In some embodiments, the detection module further includes a flow sensor, the detection end of which is located inside the hydrant body, and the flow detection pin (PA1) of the IoT main control module is connected to the signal output end of the flow sensor. Since some fire hydrants are not connected to the tap water network, but are connected to water tanks or containers with limited water capacity, the flow sensor detects the water consumption of the fire hydrant, records the water consumption of the fire, calculates the remaining water volume, and uploads this data to the upper management platform, thereby prompting timely replenishment of fire water to avoid water shortages that affect fire safety.

[0050] In some embodiments, a SIM card holder is further included, connected to the communication pin (PC8) of the IoT main control module via the communication module. By binding the SIM card to the fire hydrant's identity, the fire hydrant can be located via a base station, facilitating device status and alarm inquiries for the remote IoT monitoring module. Initial device installation registration can also be performed via the WeChat official account.

[0051] In some embodiments, a power control circuit is also included, and the power supply module is electrically connected to the communication module through the power control circuit. The power control circuit is used to monitor the remaining power of the power supply module, and upload the remaining power data to the upper management platform through the communication module in real time. Combined with positioning, it can intuitively display the power status of fire hydrants at various locations, which is convenient for management personnel to manage power. Furthermore, when the power supply module adopts a 3.6V lithium-ion battery, a voltage stabilizing circuit is also included, and the power supply module is electrically connected to the power supply pin of the Internet of Things main control module through the voltage stabilizing circuit. The voltage stabilizing circuit is an LDO circuit, which has good stability, fast load response, small output ripple, and can ensure stable power supply to various electrical devices. A voltage stabilizing chip is provided in the voltage stabilizing circuit, and the chip model is SGM2019.

[0052] In some embodiments, a push-button reset circuit is further included, one end of which is connected to the reset pin (PB12) of the IoT main control module, and the other end is connected to the reset button. The push-button reset circuit primarily allows the user to manually reset the system, returning it to its initial state. This allows administrators to conveniently interrupt the current system operation and force a system reset.

[0053] In some embodiments, a power-on reset circuit is connected to the reset pin of the IoT main control module. The main function of the power-on reset circuit is to ensure that the electronic device can be restored to its initial state when powered on so that it can operate normally.

[0054] In some embodiments, a battery power detection module is further included. The power supply module is a storage battery. The detection terminal of the battery power detection module is connected to the power pin (PC11) of the IoT main control module. The battery power detection module can intuitively monitor the remaining power of the storage battery and display it through an indicator light and a screen.

[0055] In some embodiments, an operation indicator light is also included, which is connected to the operation indication pin (PC0 / PC3) of the Internet of Things main control module. The operation indicator light can display information such as the device's operating status, communication status, and power status, making it easier for management personnel to perform maintenance.

[0056] In some embodiments, a debugging interface is further included, one end of which is connected to the debugging pin (BOOT0) of the IoT main control module. The debugging interface is a UART interface, which facilitates management personnel to debug the IoT main control module.

[0057] In some embodiments, a key detection circuit is further included, one end of which is connected to the activation button and the other end is connected to the second interrupt GPIO pin (PB11) of the IoT main control module. An administrator can manually activate the key detection circuit, interrupting the running program of the IoT main control module and prioritizing key detection to confirm whether the button is in a usable state, facilitating maintenance by the administrator.

[0058] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection of the present utility model. Therefore, based on the innovative concept of the present utility model, changes and modifications to the embodiments described herein, or equivalent structural or process transformations made using the contents of the present utility model specification and drawings, and direct or indirect application of the above technical solutions to other related technical fields are all included in the scope of protection of the present utility model patent.
