For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] The present invention will be further described below with specific embodiments, but the scope of protection of the present invention is not limited to the following embodiments.

[0024] Implementation method 1: such as Figures 1 to 5 As shown, this smart fire hydrant includes a fire hydrant body 100, a sensor module 1 disposed inside the top flange 101 of the fire hydrant body 100, a main controller 2, and a 4G communication module 3 and a power module 4 integrated in the main controller 2. The sensor module 1 includes a pressure sensor 11, a temperature sensor 12, an tilt sensor 13, and a GPS sensor 14. The signal output terminals of the pressure sensor 11, temperature sensor 12, tilt sensor 13, and GPS sensor 14 are connected to the ADC signal input terminal of the main controller 2. The data output terminal of the main controller 2 is connected to the UART command input terminal of the 4G communication module 3. The power module 4 supplies power to the sensor module 1, the main controller 2, and the 4G communication module 3. By collaboratively sensing the physical state parameters of the fire hydrant body 100 through multiple sensors, the main controller 2 integrates water pressure, temperature, tilt angle, and position data in real time, and uploads the data via the 4G communication module 3, thus realizing a fire hydrant with an intelligent monitoring system.

[0025] Implementation method 2: such as Figure 3 , 4As shown, the pressure sensor 11 of this smart fire hydrant is an MPX5050DP sensor, which is connected to the processing chip of the main controller 2 via an ADC channel; the temperature sensor 12 is an SHT30 temperature sensor, which is connected to the processing chip of the main controller 2 via an RS485 bus; the tilt sensor 13 is a LIS3DHTR triaxial accelerometer, which is connected to the processing chip of the main controller 2 via an SPI bus; the GPS sensor 14 is a SIM68M positioning module, which is connected to the processing chip of the main controller 2 via a UART interface. The processing chip of the main controller 2 in this smart fire hydrant is an FM33L025 processing chip. The tilt sensor is interrupt-triggered, and GPS data is reported synchronously with the alarm, allowing multiple sensors to work together. The 4G communication module 3 is an EC800E module, which is connected to the processing chip of the main controller 2 via UART0_TX, UART0_RX, and PWRKEY pins. Data is transmitted to the cloud platform using the MQTT protocol. The UART0 interface of the EC800E module establishes a reliable data channel in a hardware flow control manner, and the PWRKEY pin realizes the remote wake-up function, enabling the module to intelligently switch between sleep and working states.

[0026] Implementation method 3: such as Figure 1 As shown, the power module 4 of this smart fire hydrant includes an ER34615+1530 ​​lithium-ion battery pack 41 and a PMU intelligent power management module 42. The positive terminal of the lithium-ion battery pack 41 is connected to the VCC terminal of the signal sensor module 1, the VDD terminal of the main controller 2, and the VBAT terminal of the 4G communication module 3 via the PMU intelligent power management module 42, and supplies a DC 3.3-5V operating voltage to each functional unit. The 38AH lithium-ion battery, combined with the PMU power management unit, can dynamically allocate power consumption according to the operating mode of each functional module in normal sleep state / abnormal alarm state, reducing the overall power consumption of the equipment and thus extending the service life of the equipment. The remaining structures and components are as described in Embodiment 1 and will not be described again.

[0027] Implementation method 4: such as Figure 1 As shown, this smart fire hydrant also includes an IoT platform, and the 4G communication module 3 is bidirectionally connected to the IoT platform. When the IoT platform receives data indicating abnormal pressure or excessive tilt angle, it automatically triggers an alarm, realizing closed-loop management of monitoring-alarm-processing. Alarms are issued based on downlink control signals from the IoT platform. The remaining structures and components are as described in Embodiment 1 and will not be repeated.

[0028] During operation: When the tilt sensor detects that the fire hydrant tilt exceeds the set threshold, it immediately triggers an interrupt signal to wake up the main controller. Simultaneously, the GPS module is activated to obtain precise positioning coordinates, and the pressure sensor is activated to verify water pressure. The main controller uploads the encrypted alarm data packet to the IoT platform via the 4G communication module. The MQTT protocol ensures data transmission quality. When the network platform receives abnormal pressure or tilt exceeding limits, it automatically triggers an alarm. The entire system, through the cooperation of low-power chips and dynamic power management, maintains a low standby current level when the device is not in alarm mode, thus achieving ultra-long battery life.

[0029] This smart fire hydrant overcomes the shortcomings of existing fire hydrant monitoring equipment, which has limited functionality. It uses multiple sensors for collaborative monitoring of pressure, temperature, tilt angle, and positioning, along with low-power control and dynamic power management technology. This provides high-precision real-time monitoring of the fire hydrant status and multi-dimensional data fusion, while also enabling it to have an ultra-long battery life due to its low power consumption.
