Description

Technical Field

[0001] The utility model belongs to the technical field of street lamp leakage monitoring, and in particular relates to a street lamp grid management system based on lamp pole water immersion leakage early warning. Background Art

[0002] The rainy season is a high-risk period for municipal electricity use, especially for streetlights. Relying solely on leakage monitoring systems within streetlight transformers and light poles cannot fully address practical on-site issues. For example: 1. The leakage protection thresholds set for leakage monitoring terminals within streetlight transformers are relatively high, so leakage risks below the set threshold will not trigger protection. 2. The leakage monitoring equipment within light poles has inconsistent functionality across manufacturers; some only detect leakage but fail to disconnect the load in real time. Furthermore, given the vast size of streetlight systems and the numerous controls involved, the failure to promptly shut off power can easily lead to electric shock injuries in flooded areas during rainy days. Furthermore, during periods of rapid water rise during rainy days, the leakage protection devices within the light poles can be submerged in accumulated water before they can report the leakage, resulting in delayed protection and potentially endangering personal safety. Therefore, relying solely on leakage protection devices within light poles is inadequate. Utility Model Content

[0003] To solve the existing technical problems, the present invention proposes a grid-based management system for street lights based on early warning of water leakage and electric shock on lamp poles. The purpose of the present invention and the technical problems it solves are achieved by adopting the following technical solutions. The grid-based management system for street lights based on early warning of water leakage and electric shock on lamp poles proposed in the present invention includes a monitoring center server that controls multiple areas. Each area corresponds to a street light transformer substation, which is equipped with an intelligent gateway. Each area is equipped with at least one terminal for monitoring water leakage on lamp poles.

[0004] The water immersion terminal includes a micro control unit MCU, which communicates with the monitoring center server through a communication module. The micro control unit MCU is connected to the water immersion probe sensor through a state detection module I;

[0005] The intelligent gateway includes a microcontroller processing module, which is electrically connected to the status detection module II, the loop control module, the analog acquisition module, the storage module, the display module, and the leakage acquisition module respectively. The microcontroller processing module is communicatively connected to the monitoring center server through the communication module, and the communication module is communicatively connected to the communication module.

[0006] Furthermore, the water immersion terminal is installed inside the street lamp base.

[0007] Furthermore, the water-immersion terminal has a built-in charging and discharging battery.

[0008] Furthermore, the intelligent gateway can communicate and interconnect with one or more water immersion terminals.

[0009] Furthermore, the water immersion probe sensor is conical and is powered by a DC 3V.

[0010] Furthermore, the immersion terminal and the intelligent gateway are both wiredly connected to the Lora wireless communication module, and the two Lora wireless communication modules are wirelessly connected.

[0011] In summary, the invention and application of the streetlight grid management system proposed in this utility model incorporates a flood warning method and changes the original leakage protection mode of the server platform. This change greatly improves the leakage protection efficiency of the streetlight power supply line, especially in the event of sudden extreme rainfall, leaving ample time for leakage warning and emergency strategy modification.

[0012] The system allocates regional flood monitoring according to actual conditions. When encountering a regional rainstorm and sudden rise in water levels, there is no need to cut off all circuits and cause a large-scale light shutdown on site. Only the street light circuits controlled by the associated street light box transformers need to be cut off. This ensures normal living lighting in a safe environment and avoids the occurrence of leakage accidents.

[0013] At the same time, the design of the external probe monitoring terminal for flooding can promptly issue an alarm when the water level rises and submerges the probe on the road curb. This prevents leakage equipment inside street light boxes and light poles from being flooded and unable to work properly, resulting in the inability to report and handle line leakage.

[0014] Moreover, within the scope of the street light grid area, it is only necessary to install a few water-immersion terminals in low-lying areas, without the need to install the equipment inside each lamp pole, to effectively improve the problem of street light leakage management. The warning of the street light grid management system based on the lamp pole water immersion leakage warning leaves sufficient deployment time for the staff, reduces the probability of unresolved emergencies, and ensures the efficient and stable operation of municipal street lights and the property safety of the people.

In order to more clearly understand the technical means of the present invention, it can be implemented in accordance with the contents of the specification.

[0019] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0020] Example of a street light grid management system based on lamp pole flooding and leakage warning:

[0021] A streetlight grid management system based on lamppost flooding and leakage warning includes a monitoring center server 1, at least one flooding terminal 2, and a streetlight box transformer 4, which is equipped with an intelligent gateway 5;

[0022] The water immersion terminal 2 includes a microcontroller unit (MCU), which communicates with the communication module via a 485 serial port. The communication module also communicates wirelessly with the monitoring center server 1, using reliable and stable 4G signal transmission. The water immersion terminal 2 has an IP67 waterproof rating and is small in size, making it easy to install inside a light pole, providing greater safety and stability.

[0023] The flood terminal 2 inside the lamp pole has a built-in rechargeable battery that can independently supply power for more than 24 hours, ensuring uninterrupted power supply around the clock. Even if the power cable is disconnected during the day and the lamp pole is unpowered, the terminal still has backup battery power to monitor the water level and transmit water level alarms in real time to the monitoring center server 1.

[0024] The microcontroller unit MCU is wired to a water immersion probe sensor 3 through the status detection module I. The probe is conical, with a diameter of 21 mm and a length of 22 mm. It can be installed inside or outside the lamp pole or on a nearby road curb. The sensor is powered by a DC 3V power supply, which consumes little power and is safe and reliable.

[0025] The intelligent gateway 5 includes a microcontroller processing module, which is electrically connected to the status detection module II, the loop control module, the analog acquisition module, the storage module, the display module, and the leakage acquisition module respectively. The status detection module II, the loop control module, the analog acquisition module, the storage module, and the display module are all existing technologies. The microcontroller processing module communicates with the communication module through a 485 serial port. The communication module is wirelessly connected to the monitoring center server 1. At the same time, the communication module can send data to the Internet of Things cloud platform. The monitoring center server 1 can directly retrieve data from the cloud platform, and the communication module communicates wirelessly with the communication module. The on and off of the street light box transformer line is automatically controlled according to the set plan on a daily basis. The leakage condition of the line is monitored around the clock and transmitted to the monitoring center server 1 in real time. The detected leakage current exceeds the set threshold and an alarm is reported. When the current is too large and exceeds the preset protection value, the line is disconnected to play a leakage protection role.

[0026] The monitoring center server 1 plays the role of connecting the system management linkage. On rainy days, the flood terminal 2 detects that the water level exceeds the alarm value and sends the water level alarm data to the monitoring center server 1. The icon corresponding to the flood terminal 2 on the system map will keep jumping, and the alarm board will automatically scroll the alarm information. At the same time, the flood emergency strategy of the smart gateway 5 of the street light box transformer 4 will be automatically triggered, and the power-off command will be executed immediately to eliminate safety hazards. The smart gateway 5 will no longer execute the line power restoration command before receiving the water level alarm release signal. It can only operate until the water level release signal is received;

[0027] When the weather clears up or the on-site drainage is completed, the water level value monitored by the on-site water level probe sensor 3 is lower than the preset alarm value, the water level alarm is automatically released by the water level terminal 2, and the release signal is sent to the monitoring center server 1. The system map will pop up the alarm release information, and the corresponding water level terminal 2 mark will no longer jump. At the same time, the smart gateway 5 of the street light box 4 sends a command to restore the original street light switch to ensure normal lighting.

[0028] The streetlight grid management system is divided into regions. Each region has multiple light poles, and multiple light poles correspond to the same streetlight box 4. Each region has at least one flood terminal 2 to connect to the smart gateway 5 in the streetlight box 4 within the region. Grid management can more efficiently monitor flooding and leakage, ensuring the safety and reliability of the entire streetlight system.

[0029] When the area is small, the flood terminal 2 and the smart gateway 5 of the street light box transformer 4 can directly establish data linkage through Lora wireless communication. The smart gateway 5 comprehensively determines whether to implement the flood emergency strategy based on the received flood data and the collected leakage current, and automatically reports the execution result to the IoT cloud platform server. The monitoring center server 1 retrieves the required data from the cloud platform to handle flooding and leakage situations more quickly and ensure power supply safety.

[0030] The above is only a preferred embodiment of the present invention. Any simple modification, equivalent change and modification made to the above embodiment by any technician familiar with the profession based on the technical essence of the present invention without departing from the scope of the technical solution of the present invention shall still fall within the scope of the technical solution of the present invention.
