Description

Technical Field

[0001] This invention relates to the field of smart city flood monitoring and control terminal technology, and in particular to a method for monitoring and controlling urban flood points based on battery power sensing. Background Technology

[0002] During typhoons and heavy rains, low-lying areas, tunnels, and artificial rivers in cities are prone to flooding, creating waterlogging spots that affect traffic safety. With the continuous development of urban smart city initiatives, monitoring urban waterlogging spots has become an important part of smart city construction.

[0003] Urban flood monitoring methods typically deploy IoT sensors in low-lying areas of the city to detect the depth of water accumulation. This data is then transmitted via IoT communication methods such as LoRa and NB-IoT to a monitoring and control terminal (edge ​​gateway) on a roadside lamppost. Finally, the data is transmitted back to the urban flood monitoring platform from the monitoring and control terminal. Equipment on roadside lampposts typically includes a LoRa receiver, a 4G / 5G wireless terminal, a camera, and a rain sensor. All of these devices are usually powered by municipal electricity. However, severe weather such as typhoons and heavy rains can directly cause municipal power outages, resulting in power failure. The flood monitoring terminal's role is truly realized during severe weather, therefore, it is essential to ensure its continued operation during municipal power outages. While direct battery power can solve the power problem, ensuring long-term power supply usually requires installing large batteries mounted on the streetlights, increasing equipment costs and deployment challenges. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a method for monitoring and controlling urban flooding points based on battery power sensing, which can report battery power data in real time, optimize camera configuration according to battery power to enter power saving mode such as reducing frame rate and resolution, and turn off the camera when the battery power reaches the warning value to save battery power.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a method for monitoring and controlling urban flooding points based on battery power sensing, which employs a flooding point monitoring and control terminal, the flooding point monitoring and control terminal including a CPU control module, a battery, a power failure sensing module, a battery power sensing module, a camera, a 4G gateway, LoRa, and a rainfall sensing module;

[0006] The battery is connected to the municipal power supply through a power failure sensing module. After the power failure sensing module senses a municipal power failure, it outputs a signal to the CPU control module, which then provides real-time feedback on the current municipal power failure status to the management platform.

[0007] The CPU control module collects battery current and remaining power information detected by the battery power detection module in real time through the RS485 interface, and uploads the battery data to the management platform in real time.

[0008] The management platform sends the power-saving time to the flood monitoring and control terminal based on the estimated municipal maintenance time, and the CPU control module receives the power-saving requirements sent by the management platform to optimize the power-saving strategy.

[0009] In the flood monitoring and control terminal, the camera, LoRa, 4G gateway, rain sensor, etc. are all powered by a CPU-equipped control module; the CPU-equipped control module has a 12 / 24V power supply interface, an RJ45 network cable interface, an RS485 interface, and an analog switch input interface;

[0010] The 4G gateway supports dual-link backup communication, supporting both 4G wireless and wired links. When the wired link is disconnected due to typhoon weather, it directly switches to the 4G wireless link.

[0011] In a preferred embodiment, the interaction process between the monitoring terminal and the management platform is specifically as follows:

[0012] 1) After powering on, the flood monitoring terminal sends an online notification to the management platform, carrying the name, location, and serial number of the flood monitoring terminal; upon receiving the online notification, the management platform issues a confirmation response.

[0013] 2) After power-on, the flood monitoring terminal and the management platform maintain heartbeat communication at intervals;

[0014] 3) It also uploads power information at intervals and uploads power outage data in real time when a power outage occurs;

[0015] 4) The flood monitoring terminal receives the power-saving strategy issued by the management platform in real time, executes the power-saving optimization method according to the power-saving strategy, and feeds back the execution results.

[0016] In a preferred embodiment, the power-saving strategy of the flood control terminal is as follows: assuming the expected working time is T, the operating power of each module is as follows: CPU control module W1, LOAR module W2, battery power detection module W3, and rainfall detection module W4. These modules are the basic modules, and power supply to the basic modules must be guaranteed; the total power of the basic modules is:

[0017] W base =W1+W2+W3+W4

[0018] Assume the remaining battery power is The power that needs to be optimized is:

[0019]

[0020] Camera power consumption varies depending on frame rate, resolution, and infrared detection. Let's assume camera power consumption levels are categorized from highest to lowest as follows: The power consumption of a camera is related to video quality; that is, reducing video quality reduces gateway power consumption. The power consumption of a 4G gateway, from highest to lowest, corresponds to... When the camera is not working, the 4G gateway power consumption is

[0021] The four modes are respectively located as Mode 1, Mode 2, Mode 3, and Mode 4, which correspond to the camera's highest power consumption mode, camera's medium power consumption mode, camera's lowest power consumption mode, and camera off mode;

[0022] In camera off mode The remaining power consumption is the base power consumption of the 4G gateway:

[0023]

[0024] The power consumption of the camera and 4G gateway in mode 3 is Compared to mode 4, the increased power consumption is as follows:

[0025]

[0026] 1) When Time: Judgment Remaining operating power consumption;

[0027] <1> when Time: Judgment Remaining operating power consumption:

[0028] (1) When W≥W1 c ·T+W1 g • At time T: Directly enter mode 1;

[0029] (2) When W < W1 c ·T+W1 g •T time: at At this time, the camera needs to be put into the lowest power saving mode, i.e., mode 3;

[0030] <2> when At: At this time, the camera needs to be put into the lowest power saving mode, i.e., mode 3;

[0031] 2) When At that time, The camera needs to be turned off at this time, i.e., mode 4.

[0032] Compared with the prior art, the present invention has the following beneficial effects: The present invention proposes an urban flood monitoring and control terminal based on battery power sensing, which can report battery power data in real time, optimize camera configuration according to battery power to enter power saving mode such as reducing frame rate and resolution, and turn off the camera when the battery power reaches the warning value to save battery power.

[0038] A method for monitoring and controlling urban flooding points based on battery power sensing can report battery power data in real time, optimize camera configuration to enter power-saving mode based on battery power (e.g., reduce frame rate and resolution), and turn off the camera when the battery power reaches a warning value to save battery power.

[0039] like Figure 1 As shown, the CPU control module is the core control module in the internal modules of the flood monitoring and control terminal. In addition, it also includes a battery, a power failure sensing module, a battery power sensing module, a camera, a 4G gateway, LoRa, and a rainfall sensing module.

[0040] 1) The battery is connected to the municipal power supply through the power failure sensing module. After the power failure sensing module senses the municipal power failure, it outputs a signal to the CPU control module, which then feeds back the current municipal power failure status to the management platform in real time.

[0044] 5) The 4G gateway supports dual-link backup communication, supporting both 4G wireless and wired link communication. When the wired link is disconnected due to typhoon weather, it directly switches to the 4G wireless link.

[0045] Specifically, the interaction process between the flood control terminal and the management platform is as follows:

[0046] like Figure 2 As shown, specifically including

[0047] 1) Upon powering on, the flood monitoring terminal sends an online notification to the management platform, including its name, location, and serial number. The management platform then issues a confirmation response upon receiving the online notification.

[0048] 2) After power-on, the flood monitoring terminal and the management platform maintain heartbeat communication at intervals.

[0052] Assuming the expected working time is T, the power consumption of each module is as follows: CPU control module W1, LOAR module W2, battery level detection module W3, and rainfall detection module W4. These modules are the basic modules, and their power supply must be guaranteed. The total power consumption of the basic modules is:

[0053] W base =W1+W2+W3+W4

[0054] Assume the remaining battery power is The power that needs to be optimized is:

[0055]

[0056] The power consumption of a camera is affected by its frame rate, resolution, and infrared detection. This patent assumes that the power consumption levels of the camera are divided into the following categories from highest to lowest: The power consumption of a camera is related to video quality; that is, reducing video quality can also reduce gateway power consumption. The power consumption of a 4G gateway, from highest to lowest, corresponds to... When the camera is not working, the 4G gateway power consumption is

[0057] We have identified four modes: Mode 1, Mode 2, Mode 3, and Mode 4, which correspond to the camera's highest power consumption mode, camera's medium power consumption mode, camera's lowest power consumption mode, and camera off mode, respectively.

[0058] Therefore, it can be analyzed that in camera-off mode... The remaining power consumption is the base power consumption of the 4G gateway:

[0059]

[0060] The power consumption of the camera and 4G gateway in mode 3 is Compared to mode 4, the increased power consumption is as follows:

[0061]

[0062] 1) When Time: Judgment Remaining operating power consumption;

[0065] (2) When W < W1 c ·T+W1 g •T time: at At this time, the camera needs to be put into the lowest power saving mode, i.e., mode 3;

[0066] <2> when At: At times, the camera needs to be put into the lowest power-saving mode, namely mode 3.

[0067] 2) When At that time, The camera needs to be turned off at this time, i.e., mode 4.
