[0002] In the development process of the fire protection system, traditional fire hydrants usually only have the basic function of water flow release, and their operation and monitoring rely on the direct intervention of on-site personnel. This operation mode relying on manpower is not only inefficient, but may not be able to respond in real time in case of emergency, thus affecting the fire protection efficiency and public safety. With the development of technology, especially the application of Internet of Things technology, remote monitoring and automatic control technology have become the key technologies to improve the response ability of public safety systems.

[0003] In view of the above problems, there have been some solutions in the prior art to try to improve the intelligence level of fire protection equipment by integrating electronic devices into fire protection equipment. For example, the use status of fire hydrants is observed through remote monitoring cameras or the water pressure is detected through basic sensors. However, these solutions usually lack a comprehensive control system to monitor and control the specific operation status of fire hydrants in real time, such as the specific flow condition of fluids and the specific position information of fire hydrants. In addition, these systems often cannot remotely adjust the flow rate of fire hydrants or respond to remote commands in time, thus limiting their practicability and efficiency in case of emergency.

[0018] To describe in detail the technical content, structural features, achieved objectives and effects of the present utility model, the following is described in detail in conjunction with the embodiments and with reference to the accompanying drawings.

[0019] This embodiment discloses a fire hydrant remote monitoring device for monitoring and automatically controlling the real-time state of the fire hydrant, improving the safety performance and response efficiency of the fire hydrant.

[0020] As Figure 1 and Figure 2 shown, the monitoring device includes a controller 1, a status sensor 2, a wireless communication module 3, a fluid control valve 4 and a GPS positioning module 5 provided on the fire hydrant.

[0021] The fluid control valve 4 and the status sensor 2 are arranged inside the outlet of the fire hydrant. The fluid control valve 4 is used to control the open / close state of the outlet, that is, the fluid control valve 4 controls the opening and closing of the fire hydrant outlet and the opening size.

[0022] The status sensor 2 is used to detect the water flow state at the outlet. The controller 1 is electrically connected to the status sensor 2, the wireless communication module 3, the fluid control valve 4 and the GPS positioning module 5. The controller 1 can communicate with the remote server according to the wireless communication module 3, and the controller 1 can also control the opening degree of the fluid control valve 4 according to the signal detected by the status sensor 2 or the signal sent by the remote server.

[0023] For the fire hydrant remote monitoring device disclosed in this embodiment, by integrating the controller 1, the status sensor 2, the wireless communication module 3, the fluid control valve 4 and the GPS positioning module 5 on the fire hydrant, a comprehensive monitoring and control system is constructed. This system allows the fire hydrant to not only remotely monitor its status, but also control the opening and closing of the water flow through remote commands. This design significantly improves the operation flexibility and response speed of the fire hydrant. Especially in the case where no one can quickly reach the scene, the remote control function can quickly start or close the water flow, greatly improving the efficiency and effect of emergency response.

[0024] In addition, the water flow state data detected by the state sensor 2 and the precise position information provided by the GPS positioning module 5 can be transmitted back to the remote server in real time, enabling real-time monitoring and data analysis of the usage of fire hydrants. This not only helps optimize resource allocation, improve the usage efficiency of fire hydrants, but also enables quick location and maintenance in case of failures, significantly enhancing the reliability and safety of the system.

[0025] On the other hand, the state sensor 2 includes one or more of a water flow sensor, a water pressure sensor, and an inclination sensor.

[0026] The water flow sensor is used to detect the water flow velocity at the outlet of the fire hydrant to determine the water flow velocity at the outlet.

[0027] The water pressure sensor is used to detect the water pressure at the outlet of the fire hydrant to determine whether the water pressure is compliant.

[0028] The inclination sensor is used to detect the inclination angle of the fire hydrant outlet to determine whether the fire hydrant is skewed.

[0029] The controller 1 obtains the data of the water flow sensor, the water pressure sensor, and the inclination sensor in real time and transmits this data back to the remote server. In this way, when an abnormality in the water flow, water pressure, or inclination of the fire hydrant is monitored, the location of the fire hydrant can be quickly located based on the information fed back by the GPS positioning module 5 for maintenance.

[0030] In addition, when there is a fire emergency, the controller 1 controls the fluid control valve 4 to open the outlet of the fire hydrant to automatically discharge water based on the command received from the remote server.

[0031] On the other hand, the monitoring device further includes an alarm 6 provided on the fire hydrant, and the alarm 6 is electrically connected to the controller 1. When it is detected that the fire hydrant is in an abnormal state, such as detecting leakage through the water flow sensor or detecting substandard water pressure through the water pressure sensor, the alarm 6 emits an alarm signal to remind nearby personnel to perform maintenance in a timely manner.

[0032] On the other hand, as Figure 3 , the monitoring device further includes a switching power supply 7, a voltage regulator 8 electrically connected to the switching power supply 7, and a voltage stabilizer 9 electrically connected to the voltage regulator 8.

[0033] The switching power supply 7 is used to convert the mains power into a first power signal U1 with a first voltage and being a direct current.

[0034] The voltage regulator 8 converts the first power signal U1 into a second power signal U2 with a second voltage.

[0035] The voltage regulator 9 is used to regulate and transform the second power supply signal U2 to output a third power supply signal U3 with a third voltage.

[0036] The first voltage is greater than the second voltage, and the second voltage is greater than the third voltage.

[0037] The third power supply signal U3 is used to supply power to the controller 1, the status sensor 2, the wireless communication module 3, the fluid control valve 4, and the GPS positioning module 5.

[0038] In this embodiment, the switching power supply 7 converts the 220V AC power from the mains into a first power supply signal U1 of 12V (the first voltage). The voltage regulator 8 converts the 12V first power supply signal U1 into a 5V second power supply signal U2. Then, the voltage regulator 9 regulates and further transforms the second power supply signal U2 to output a stable third power supply signal U3 of 3.3V.

[0039] Further, a first decoupling capacitor C1 and a second decoupling capacitor C2 connected in parallel are provided on the power supply line between the voltage regulator 8 and the voltage regulator 9. The other ends of the first decoupling capacitor C1 and the second decoupling capacitor C2 are grounded. The first decoupling capacitor C1 is much larger than the second decoupling capacitor C2, and the second decoupling capacitor C2 is used to filter out low-frequency signals. It should be noted that as long as the first decoupling capacitor C1 is more than ten times larger than the second decoupling capacitor C2, the first decoupling capacitor C1 is much larger than the second decoupling capacitor C2. In this embodiment, the larger first decoupling capacitor C1 can better smooth the power supply signal because it can store more charge, thus providing a more stable voltage output.

[0040] Specifically, the first decoupling capacitor C1 is 220uF, and the second decoupling capacitor C2 is 0.1uF. The 220uF capacitor can store a large amount of charge, and the 0.1uF capacitor has a low ESL and is suitable for high-frequency circuits. Therefore, the combination of the two can effectively reduce the power ripple, reduce the power noise, and improve the response time of the transient current.

[0041] On the other hand, a one-way diode D0 is also provided on the power supply line between the voltage regulator 8 and the voltage regulator 9 to prevent the power supply signal from flowing back to the voltage regulator 8.

[0042] On the other hand, a third decoupling capacitor C3 and a fourth decoupling capacitor C4 for filtering out low-frequency signals are provided in parallel at the output end of the voltage regulator 9.

[0043] Specifically, both the third decoupling capacitor C3 and the fourth decoupling capacitor C4 are 0.1uF.

[0044] On the other hand, a light-emitting diode D1 is also provided between the output terminal of the voltage regulator 8 and the ground terminal. The light-emitting diode D1 is used as an indicator to indicate the output state of the voltage regulator 8.

[0045] The above-disclosed are only the preferred embodiments of the present invention. Of course, the scope of the rights of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
