Description

Technical Field

[0001] This invention relates to the field of substation flood control technology, and in particular to an automated online collaborative flood control system and method for substation flood control. Background Technology

[0002] In the event of sudden flooding caused by severe weather such as torrential rain and strong convection, many substations face insufficient staffing and delayed drainage responses during flood season. If a substation experiences significant flooding, it could lead to a complete shutdown, causing unnecessary losses and inconvenience to businesses and residents, severely impacting both production and daily life.

[0003] During flood season, substation staff often rely on manual observation for flood prevention and control. When personnel discover water accumulation, they sequentially activate water pumps to control drainage. This process is not only time-consuming and labor-intensive but also inefficient, failing to ensure timely detection and treatment of water accumulation. If drainage is delayed, cables may remain submerged in water for extended periods, leading to a decline in cable insulation and even the risk of cable explosion upon contact with water, jeopardizing the safe operation of the entire substation's power supply equipment.

[0029] Embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While some embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the present invention. It should be understood that the drawings and embodiments of the present invention are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0030] In the event of sudden flooding caused by severe weather such as torrential rain and strong convection, substations require a large number of flood control personnel to promptly carry out flood prevention and control measures. However, some small and medium-sized substations lack sufficient on-duty personnel, and the existence of multiple scattered flood control stations within substations can easily lead to untimely drainage responses. Cable layers and cable trenches within substations are prone to water accumulation due to their low-lying location. To prevent cables from being submerged in water, extensive manual inspections and operation of water pumps are necessary for drainage, resulting in extremely high costs.

[0031] To address the problems of untimely flood drainage and low flood control efficiency in substations, this invention provides an automated, online, collaborative flood control system for substations. The system includes: multiple flood control terminals located on the bank of the substation's flood control site; a server connected to the terminals, used to receive real-time flood control data uploaded by the terminals, and to perform different deployment and control actions on the terminals based on the flood control data, substation water network data, and meteorological environmental data, for timely and effective flood control; each flood control terminal includes: such as... Figure 1 , Figure 2As shown, the movable main body 1 includes a waterproof housing 11 and a mobile device 12 installed on the waterproof housing 11. The waterproof housing 11 also houses a data processing device 111 and a communication device 112. The data processing device 111 is used to receive and process flood control data, and the communication device 112 is used to connect with a cloud-based collaborative system. A liquid level sensor 2 is connected to the data processing device 111 via a data cable. When in use, the liquid level sensor 2 is led out from the data processing device 111 and placed in the water at the flood control site of the substation to be monitored. A pumping assembly 3 includes a water pump 32, a pumping pipe 31, and a drainage pipe 33. The water pump 32 is installed inside the waterproof housing 11. One end of the pumping pipe 31 is placed in the water at the flood control site of the substation, and the other end is connected to the water pump 32. One end of the drainage pipe 33 is installed on the water pump 32, and the other end is located at the drainage point.

[0032] The servers of the substation flood control system need to take into account both local real-time control and global collaborative scheduling. Edge servers can be deployed locally at the substation or in the regional control center, which have the characteristics of localized data processing, low-latency control command issuance, and terminal status monitoring. Alternatively, cloud or regional servers can be deployed at the power company's dispatch center, which have the characteristics of global data fusion, long-term trend analysis, multi-substation collaborative scheduling, and meteorological data docking.

[0033] The server performs data cleaning on the received flood control data, removing outliers and optimizing real-time data using moving average filtering. Flood control data from the flood control terminals is correlated and mapped with substation water network data and meteorological environmental data, while standardizing data formats such as liquid level (m), flow rate (m³ / h), and rainfall (mm). For example, flood control data shows a liquid level of 1.2m at site A, substation water network data shows site A belongs to the XX drainage network with a pipe diameter of 500mm, and meteorological environmental data shows a rainfall of 20mm for the next 3 hours.

[0034] Flood control data can include liquid level, water flow velocity, water pressure, terminal location, and the operating status of water pump 32. Flood control data directly reflects the current water accumulation situation and terminal operating status, such as whether the liquid level exceeds the standard or whether the flood control terminal is malfunctioning. Flood control data is acquired by the liquid level sensor 2 of the flood control terminal and transmitted to the server via communication equipment 112.

[0035] Flood control data serves as feedback signals in the control closed loop, verifying the effectiveness of control actions and avoiding blind control, such as whether the water level drops after pumping is started. Relying solely on meteorological data may lead to misjudgments due to local terrain differences, such as low-lying areas near substations; relying solely on water network data cannot detect real-time water accumulation.

[0036] The substation's water network data can include pre-entered information such as drainage network routing, node locations, pipe diameters, design flow rates, pump station locations, gate distribution, and low-lying area distribution; as well as real-time updates of network flow, pipeline pressure, gate opening, and pump station operating status. Water network data can be manually entered through a server-side management system, or imported from CAD (Computer-Aided Design) or BIM (Building Information Modeling) model files for automatic analysis of the water network topology. Alternatively, flow sensors, pressure sensors, and opening sensors can be installed at network nodes, pump stations, and gates, and connected to the server via the substation's industrial Ethernet network for real-time updates of the water network data every minute.

[0037] Substation water network data can be used to prioritize dispatching flood control terminals to water accumulation points based on the pipe network confluence path, avoiding conflicts between pumping pipelines and the pipe network; the optimal drainage point can be selected according to the carrying capacity of the drainage pipe network to avoid backflow in the pipe network caused by drainage; and the water flow diffusion speed can also be simulated through the pipe network topology to pre-dispatch terminals to block the diffusion path.

[0038] Meteorological environmental data can include real-time rainfall, forecast rainfall, rainfall duration, rainfall intensity, wind speed, wind direction, and temperature. This data can be connected to local meteorological data sharing platforms to obtain rainfall forecasts and rainfall intensity levels for the next 24 hours.

[0039] The importance of meteorological data lies in preventing the spread of floodwaters. Waiting until the water level exceeds the warning level before taking action may lead to a rapid rise in water levels due to continued rainfall, causing the optimal drainage opportunity to be missed. Based on the predicted rainfall intensity, flood control terminals can be deployed in advance to high-risk areas for preventative drainage, such as to historically significant rainfall points. If the weather forecast indicates no continued rainfall, pumping power can be appropriately reduced to conserve energy.

[0040] The fusion of these three types of data to calculate risk values ​​enables a closed-loop process of early risk prediction, accurate hazard location, and efficient hazard mitigation. For example, relying solely on liquid level data from flood control systems results in a delayed response from flood control terminals; relying solely on meteorological data ignores the drainage capacity of the water network; and relying solely on water network data leads to a lack of real-time hazard feedback.

[0041] The server has a built-in flood control risk assessment model that calculates risk values ​​based on three types of fused data. It can employ fuzzy comprehensive evaluation or machine learning models, such as LSTM (Long Short-Term Memory) networks trained on historical data, to improve prediction accuracy. Based on the calculated risk values ​​and the status of flood control terminals, the server generates different deployment and control instructions.

[0042] Different control commands, by setting alarm thresholds in the server and comparing the water level in the flood control data with the preset alarm thresholds, enable the flood control terminal to start and stop the pumping component 3. Ultimately, this minimizes the time for water to recede and maximizes drainage efficiency.

[0043] The layout of different flood control terminals can vary. For example, based on the water network topology, terminals can be placed at the intersection of multiple pipe networks, where water accumulates most quickly. Alternatively, based on substation topography data, terminals can be placed in low-lying areas. They can also be placed near drainage interfaces to shorten drainage pipe lengths and improve drainage efficiency. For low-risk areas, flood control terminals can be distributed more widely; for high-risk areas, they can be concentrated for efficient pumping. Terminals in low-risk areas can also be moved to high-risk areas.

[0044] Installing the mobile device 12 allows the flood control terminal to be quickly moved from its standby point to a new waterlogged area. Substation flooding may occur in different locations due to rainfall distribution and terrain variations; the mobile device 12 prevents the flood control terminal from being confined to a fixed location for monitoring and pumping. The server can dispatch idle terminals to support high-risk areas based on the severity of the hazard in multiple regions.

[0045] Some low-lying areas of the substation may be covered by weeds and gravel. The mobile device 12 needs to be able to cross obstacles to reach the bank of the substation's flood control station to ensure that the liquid level sensor 2 accurately enters the water and the pumping pipe 31 is effectively connected. The mobile device 12 can use solid rubber wheels or pneumatic tires, with a motor driving the mobile body 1; it can also use tracks made of highly wear-resistant rubber to drive the mobile body 1; and it can also be equipped with small winches or towing hooks at some flood control terminals to be moved by other flood control terminals, thereby improving coordination.

[0046] Substation flood control terminals are constantly exposed to high humidity and may be temporarily submerged during heavy rains, and may also be subject to splashing rainwater and moisture in the surrounding area. The waterproof casing 11 provides physical waterproofing, resistance to environmental corrosion, and electromagnetic interference.

[0047] Data processing equipment 111 and communication equipment 112 are housed within a waterproof enclosure 11 when exposed to water. The waterproof enclosure 11's sealing strips and waterproof joints prevent water intrusion, ensuring the basic functionality of the equipment. Substation water bodies may contain small amounts of oil, metal ions, etc.; the waterproof enclosure 11 also isolates corrosive liquids, extending equipment lifespan. Substations experience strong electromagnetic fields; the metal waterproof enclosure 11 forms a Faraday cage, reducing electromagnetic interference to communication equipment 112 and data processing equipment 111, ensuring the stability of data processing and transmission.

[0048] The data processing device 111 can employ an embedded motherboard, a programmable controller, or an edge computing module. The data processing device 111 preprocesses and removes outliers from the liquid level sensor 2. Simultaneously, it compresses the original liquid level sensor 2 data by adjusting the mean and peak values, encapsulates it according to a standard protocol, and transmits it to the server to reduce communication throughput, lower bandwidth costs, and reduce latency.

[0049] Communication device 112 is used to connect to the cloud-based collaborative system for data transmission between the flood control terminal and the server, and also for data transmission between flood control terminals. Communication device 112 can use LoRa (LoRa communication mode, long-range wireless communication technology) or an RS485 communication interface for data transmission. The server communicates with the cloud-based collaborative system, and the flood control terminal accesses the cloud-based collaborative system through communication device 112 to achieve online collaboration with the server.

[0050] The level sensor 2 is an immersion sensor that directly contacts the water body, avoiding interference from environmental factors such as air, light, and temperature, ensuring that the data accurately reflects the actual water level. Even with water surface fluctuations or floating objects, the immersion sensor can still operate stably. The level sensor 2 can be an immersion hydrostatic level gauge, an immersion cable level gauge, or a float level gauge.

[0051] The water pump 32 can be a miniature self-priming centrifugal pump or a submersible pump. The miniature self-priming centrifugal pump does not require pre-priming and can be embedded in the waterproof housing 11. The motor and impeller of the submersible pump are housed in the waterproof housing 11, and the water inlet extends to the water in the flood control station of the substation through the water inlet pipe 31, avoiding direct immersion of the motor in water. It is suitable for scenarios with a water depth of 0.5m or more and has a higher efficiency than the centrifugal pump.

[0052] The pump 32, including its motor and impeller, is housed within a waterproof casing 11. This casing prevents silt and gravel from entering the substation's accumulated water. The waterproof casing 11 also prevents impurities from entering the pump body, ensuring that the accumulated water is only drawn in after being filtered through the pumping pipe 31. This reduces the risk of impeller wear and blockage. The pump 32, integrated with the flood control terminal within the waterproof casing 11, reduces the need for external piping connections, prevents pipe detachment during relocation, and improves the overall reliability of the terminal.

[0053] One end of the pumping pipe 31 is pre-immersed in the water at the substation's flood control site, ensuring the inlet is below the water surface. A stainless steel filter screen can be installed at the inlet of the pumping pipe 31 to filter out impurities such as mud, fallen leaves, and gravel carried by the accumulated water, preventing them from wearing down the impeller or clogging the pipe after entering the water pump 32. The other end is connected to the inlet of the water pump 32. One end of the drainage pipe 33 is connected to the water pump 32, and the other end is set at the drainage point, quickly transferring the accumulated water at the substation's flood control site to a safe drainage point.

[0054] When the server or data processing device 111 determines that the liquid level is greater than the preset alarm threshold, it sends a control action to drive the pumping assembly 3 and start the water pump 32. After the water pump 32 starts, the internal impeller rotates at high speed, creating a negative pressure at the inlet of the pumping pipe 31. Using atmospheric pressure, the accumulated water is drawn into the pumping pipe 31 and transported to the chamber of the water pump 32. The water pump 32 provides power to increase the energy of the water flow and ensures smooth water delivery. One end of the drainage pipe 33 is connected to the outlet of the water pump 32, and the other end extends to the drainage point. Through the guiding effect of the drainage pipe 33, the pressurized water flow is directed to the drainage point.

[0055] The automated online collaborative flood control system for substation flood control provided by the present invention includes: a server and multiple flood control terminals. Each flood control terminal includes a movable body 1, a liquid level sensor 2, and a pumping assembly 3. The liquid level sensor 2 transmits the collected flood control data to the movable body 1, and then uploads it to the server via the data processing device 111 and the communication device 112 in the movable body 1.

[0056] The server connects to multiple flood control terminals, enabling simultaneous control of multiple flood control terminals and unified scheduling of multiple sites. After comprehensively analyzing flood control data, substation water network data, and meteorological environmental data, the server implements precise deployment and action control for different flood control terminals.

[0057] The water pumps 32, pumping pipes 31 and drainage pipes 33 at each flood control terminal quickly drain the accumulated water at the flood control station to the designated drainage point. At the same time, the mobile main body 1 enhances the deployment flexibility, and ultimately realizes real-time monitoring of flood control data, collaborative decision-making based on multi-source data and efficient execution of drainage actions, thereby solving the problems of untimely flood control drainage and low flood control efficiency of substations.

[0058] As an alternative solution, such as Figure 1 , Figure 2 As shown, the flood control terminal also includes: a light sensor, a camera, and a searchlight 4; the light sensor is installed inside the waterproof housing 11, which includes a transparent cover, and the light sensor is installed inside the waterproof housing 11 at a position corresponding to the transparent cover; both the light sensor and the searchlight 4 are connected to the data processing device 111; the camera is mounted on the waterproof housing 11 via a rotating pan-tilt unit, and the camera is connected to the data processing device 111.

[0059] The light sensor can automatically detect the ambient light intensity and automatically control the spotlight 4 to provide illumination for the camera. For example, when monitoring water accumulation at night, the light is dim, and the spotlight 4 is automatically activated to provide illumination for the camera, ensuring a clear image and helping the flood control terminal avoid obstacles when moving.

[0060] A light sensor collects ambient light intensity in real time, for example, every 100ms, and transmits the data to a data processing device 111 via a data cable. The data processing device 111 compares the real-time light intensity value with a preset light threshold, for example, the light threshold can be set to 100 lux.

[0061] When the real-time light intensity value is less than or equal to the light threshold and the device is powered on without manual locking, a start command is generated. The drive circuit of the searchlight 4 receives the command from the data processing device 111, turns on the power supply of the searchlight 4, and the searchlight 4 lights up.

[0062] When the real-time light intensity value is greater than or equal to the light threshold and there is no manual locking, the data processing device 111 outputs a shutdown command to cut off the power to the searchlight 4, thus achieving automatic shutdown. If the user presses the lighting switch 15, the switch signal is preferentially input to the data processing device 111, the device disables the automatic control logic, and forcibly outputs a start or stop command.

[0063] Light sensors need to be compatible with industrial-grade low power consumption and small size requirements, and be able to accurately detect light changes from 0 to 2000 lux, covering daytime to nighttime light variations. Digital light sensors or analog light sensors can be used.

[0064] The light sensor is an electronic component, and direct exposure to the outside environment can cause it to short-circuit and be damaged by rainwater and moisture. The waterproof housing 11 can isolate water and impurities. At the same time, the light sensor is located inside the waterproof housing 11 at a position corresponding to the transparent cover, allowing external light to enter the housing without obstruction and ensuring that the sensor can accurately reflect the ambient light.

[0065] Cameras are installed on flood control terminals to provide staff with visual monitoring, intuitively presenting the on-site situation, thus requiring only a small number of personnel to assist in remote decision-making. Liquid level sensor 2 provides water level data, while the camera can capture real-time images of the water accumulation area, floating debris, and the surrounding environment. Server and maintenance personnel can assess the severity of the emergency through video footage and optimize server scheduling strategies.

[0066] The video feed from the camera can also confirm whether the searchlight 4 is providing effective illumination, whether the flood control terminal has been accurately moved to its target location, and whether pumping has caused a drop in water level. Simultaneously, the searchlight 4 also provides illumination for the camera, ensuring a clear image. The camera can be an industrial-grade waterproof camera with infrared night vision capabilities.

[0067] A rotating pan-tilt unit, such as a two-axis unit, can be used to expand the monitoring range and eliminate blind spots. After the flood control terminal is moved to a new location, the rotating pan-tilt unit can rotate the camera to aim at waterlogged areas, drainage points, or obstacles. Multi-area monitoring can be completed simply by rotating the pan-tilt unit, without moving the flood control terminal, thus reducing energy consumption and mechanical wear. For example, remote focusing can be achieved by controlling the pan-tilt motor through data processing equipment 111. When equipment in the substation obstructs the view, the rotating pan-tilt unit can also adjust the camera to avoid obstruction and focus on critical areas.

[0068] Flood control terminals need to operate in complex lighting environments, such as during heavy rain, cloudy days, at night, and in low-light scenarios like tunnel substations. The light-sensing automatic lighting function solves the problem of insufficient light during nighttime flood control, and the lighting design improves operational safety. The waterproof design of the flood control terminal is suitable for severe weather conditions such as heavy rain and humidity. The waterproof housing 11 and searchlight 4 enable the flood control terminal to overcome the limitations of traditional equipment's poor environmental adaptability. Simultaneously, the monitoring images provided by the camera allow staff to monitor multiple flood control stations simultaneously, eliminating the need for extensive on-site inspections and significantly improving the efficiency of flood control and disaster relief.

[0069] As an alternative solution, such as Figure 1 , Figure 2 As shown, the mobile device 12 includes a chassis 5, wheels 6, a push handle 7, and a motor; the chassis 5 is disposed on the first side of the waterproof housing 11 and fixed to the waterproof housing 11, the wheels 6 are disposed on the second side of the chassis 5, and the second side is disposed opposite to the first side; the output shaft of the motor is connected to the drive shaft of the wheels 6; the push handle 7 is fixed on the chassis 5 and fixed to the waterproof housing 11, and the height of the push handle 7 relative to the wheels 6 is within a preset height range.

[0070] The chassis 5 is the basic framework of the movable body 1, providing structural support and serving to integrate and distribute the weight of the components on the movable body 1. The chassis 5 secures the waterproof shell 11, wheels 6, motor, push handle 7, and other components into a single unit, ensuring the relative stability of each part and preventing loosening of connections due to vibration during movement. Since the weight of the movable body 1 is concentrated, the chassis 5 distributes pressure through a large contact area with the ground, also preventing the end from sinking into soft ground.

[0071] The chassis 5 can be made of 304 stainless steel or high-strength aluminum alloy with a thickness of 5mm or more. It can withstand minor collisions with the equipment foundation and cable trench edges during movement, and protect the electronic equipment inside the housing from impact.

[0072] The motor converts its power into the movement of the wheels 6 through a transmission structure, thereby improving the deployment flexibility of the mobile unit 1 at different flood control stations. The motor provides power transmission and motion control for the mobile unit 1, allowing workers with less strength to easily move the mobile unit 1 through the combined action of the push handle 7 and the motor.

[0073] The rotational power output by the motor is transmitted to the drive shaft of the wheel 6 through a transmission structure, such as gears, couplings, or belts, causing the wheel 6 to rotate and providing the moving power for the movable body 1. The motor may also include a reverse braking function, transmitting braking force to the wheel 6 through a transmission connection to achieve rapid and stable stopping at the end. The motor can be a DC geared motor, servo motor, stepper motor, brushless DC motor, etc.

[0074] Wheels 6 allow the movable body 1 to adapt to diverse terrains within the substation during movement, such as hardened inspection routes, muddy areas, waterlogged areas, and gravel roads. Wheels 6 may also include braking devices for securing the movable body 1 once it has come to a stop. Wheels 6 can be made of solid rubber, tracked wheels, pneumatic rubber, or polyurethane-coated wheels.

[0075] The push handle 7 is a component used for manual intervention and auxiliary operation. It can serve as a force-bearing point, facilitating collaborative handling by multiple people. When the terminal malfunctions or needs to be moved, the operator can manually push the terminal using the push handle 7 to prevent equipment failure. After automatic movement, if there is a deviation between the movable body 1 and the target position, the operator can fine-tune the position using the push handle 7 to ensure precise alignment of the water pumping pipe 31 and the liquid level sensor 2.

[0076] The push handle 7 is rigidly connected to the chassis 5 and the waterproof housing 11. It can be welded with stainless steel square tubing, resulting in a simple and high-strength structure suitable for long-term use of the movable main body 1 within the substation without the need for frequent folding. The handle of the push handle 7 can also be wrapped with a textured rubber anti-slip sleeve to increase grip friction and prevent slipping in rainy weather or when hands are wet.

[0077] The height of the wheel 6 is within a preset range because the wheel 6 serves as the grounding reference for the mobile device 12. When the terminal moves across different surfaces, the ground plane of the wheel 6 remains a stable reference surface. The height of the handle 7 conforms to ergonomic design while also ensuring the terminal's center of gravity balance. The optimal grip height for an adult standing with their arm naturally hanging down is approximately 80cm to 100cm. Pushing the terminal at this height eliminates the need to bend over or raise their hand, reducing operator fatigue. Therefore, the preset height range for operators is 80cm to 100cm.

[0078] The push handle 7 can also be designed with a telescopic tube, allowing its height to be adjusted between 80cm and 100cm to accommodate operators of different heights. The preset height range of the push handle 7 ensures that the operator's grip height meets ergonomic requirements under any working condition.

[0079] In summary, chassis 5 serves as the supporting frame, integrating components and bearing loads; the transmission connection between the motor and wheels 6 ensures power transmission and precise movement; and the push handle 7 provides manual emergency and auxiliary operation. The coordinated action of these components adapts to the heavy loads, diverse terrains, and emergency needs of flood control and disaster relief, ultimately achieving flexible deployment capabilities with both automatic movement and manual intervention, thus fitting the complex and dynamic scenarios of flood control in substations.

[0080] As an optional solution, the pumping pipe 31 and the data cable are set on the third side of the waterproof housing 11, which is the side of the waterproof housing 11 closest to the flood control water area; the data cable includes a fixed section and a flexible section; the first end of the fixed section passes through the third side and is detachably connected to the data processing device 111, and the fixed section is set horizontally so that the straight distance between the flexible section and the pumping pipe 31 is not less than a preset distance threshold.

[0081] The data cable is detachably connected to the data processing device 111. The connection can be made using aviation plugs, waterproof connectors, terminal blocks, etc. If the sensor malfunctions or the data cable is worn or damaged, the data cable can be directly disconnected to replace the sensor or data cable without disassembling the waterproof housing 11 or soldering the wiring, reducing maintenance difficulty. On-site repairs at the substation are possible, preventing flood control interruptions and avoiding problems such as untimely flood drainage and low flood control efficiency caused by equipment failure.

[0082] The data cable connects the level sensor 2 to the data cable plug. The data cable plug connects to the data processing device 111, transmitting the water level data collected by the level sensor 2 to the data processing device 111 in real time, providing data support for flood control decision-making. When operating the flood control terminal manually, the level sensor is not required. The data cable integrates a power supply cell and can also power other devices, eliminating the need for additional wiring and simplifying the structure of the flood control terminal.

[0083] Different scenarios may require different sensors. For example, different models of level sensors are needed for shallow and deep water areas. The detachable connection only requires matching the data cable plug specifications, which can support quick sensor replacement and improve the versatility of flood control terminals.

[0084] The fixed section can be integrated with the flexible section, or a rigid sheath can be used at the connection end between the data cable and the data processing equipment to ensure that the data cable extends horizontally to a preset length when it is led out. The preset length of the fixed section ensures that when the flexible section hangs down or extends naturally from the end of the fixed section, it will not stick to the water pipe 31 due to gravity or end movement.

[0085] The pumping pipe 31 also extends from the third side. The horizontally positioned fixed section ensures a lateral distance between the two at the exit point, preventing the flexible section from getting too close to the starting point of the pumping pipe and causing subsequent entanglement. The flexible section can use corrugated pipe or braided pipe sheaths to improve wear resistance. The distance between the flexible section extending naturally from the end of the fixed section and the pumping pipe 31 is greater than the distance threshold, preventing it from sticking to the pumping pipe 31 due to gravity or movement of the flood control terminal.

[0086] When the water pump 31 is in operation, it will generate high-frequency vibrations due to the vibration of the water pump 32 and the impact of water flow. If the flexible section is in close contact with the pipe, long-term friction will cause wear on the cable insulation layer, leading to a short circuit. Maintaining a preset distance threshold can prevent the flexible section from being pulled or broken due to movement of the water pump 31, and can also prevent the liquid level sensor from being sucked into the water pump 31 if it is too close. If the water pump 31 is made of metal, the static electricity or electromagnetic induction generated by the water flow impact during operation may interfere with the weak signal transmitted by the data line. Maintaining a sufficient distance can also reduce electromagnetic coupling interference and ensure data transmission accuracy.

[0087] The preset distance threshold is greater than the amplitude of pipe vibration and cable sway to ensure that the flexible section does not come into contact with the pumping pipe 31 under extreme conditions. The preset distance threshold can be set to 20cm or more. By simulating conditions such as the movement of the flood control terminal and the full-load operation of the water pump 32, the minimum distance between the flexible section and the pipe is tested to ensure no contact and no signal interference, and the preset distance threshold is finally determined.

[0088] like Figure 2 As shown, the pumping pipe 31 and the drainage pipe 33 extend from the side of the movable main body 1 closest to the flood control area. The pumping pipe 31, along with the data cable, is inserted into the water at the substation's flood control site. The liquid level sensor connected to the data cable transmits the liquid level information to the data processing device 111. The data processing device 111 controls the water pump 32 to pump water, thereby drawing the accumulated water at the flood control site into the water pump 32 through the pumping pipe 31, and then discharging it to the drainage point through the drainage pipe 33 connected to the water pump 32.

[0089] In summary, the design of the data cable—features detachable connection, a horizontally fixed section, and a flexible section—is tailored to the reliability and practicality of substation flood control scenarios. The detachable connection improves equipment maintainability, the horizontally fixed section ensures a secure data cable connection, and the flexible section provides a degree of bending capability, allowing it to swing freely under conditions such as equipment movement and water flow impact. Ultimately, this ensures the stable operation of the flood control terminal under complex conditions, providing safety guarantees for flood control data transmission and pumping operations.

[0090] As an optional solution, an alarm light 8 is also included, which is connected to the data processing device 111 and is used to issue an alarm when the water level reaches a preset height; an electrical switch is also installed inside the waterproof housing 11, such as... Figure 2As shown, the electrical switches include: a water pump switch 13, an alarm switch 14, a lighting switch 15, an emergency stop switch 16, and an automatic / manual switch 17; the water pump switch 13 is connected to the power supply of the water pump 32, the alarm switch 14 is connected to the power supply of the alarm light 8, the lighting switch 15 is connected to the power supply of the searchlight 4, the emergency stop switch 16 is connected to the power bus, and the power bus is connected to the power supply of the water pump 32, the power supply of the alarm light 8, and the power supply of the searchlight 4, respectively.

[0091] Alarm light 8 needs to be adapted to the flood control environment of substations, and has the characteristics of high visibility, waterproof and anti-interference, and resistance to harsh environments. Alarm light 8 can be an integrated LED sound and light alarm light, a flashing alarm light, or a waterproof combination alarm light, etc.

[0092] In unattended scenarios, when the water level reaches a preset height, the alarm light 8 can alert the substation on-site inspection personnel or surrounding personnel through sound and light signals that there is a risk of water accumulation in the area, while preventing personnel from accidentally entering dangerous areas, such as the flooding of cable trenches leading to electric shock.

[0093] Alarm light 8 is connected to data processing device 111. On one hand, data processing device 111 can determine whether the water level has reached the preset height and send an activation signal to alarm light 8. On the other hand, the activation status of alarm light 8 is uploaded to the server through data processing device 111, allowing maintenance personnel to intuitively determine whether the terminal has triggered an alarm on the monitoring platform, assisting in remote decision-making. In the multi-flood control terminal online mode, when any flood control terminal triggers an alarm, the server can simultaneously control the activation of alarm lights 8 on other associated flood control terminals, expanding the warning range and improving the efficiency of emergency response.

[0094] The data processing device 111 receives water level data from the liquid level sensor 2 in real time and compares it with preset alarm thresholds. For example, the preset alarm thresholds may include a low water level threshold of 5m and a high water level threshold of 8m. When the water level is greater than the low water level threshold, the data processing device 111 sends a start signal to the alarm switch 14, triggering the alarm light 8 to flash yellow and the buzzer to sound a low-volume alarm. When the water level is greater than the high water level threshold, the alarm light switches to solid red and the buzzer sounds a high-volume alarm, while simultaneously triggering a global early warning by synchronizing with the server.

[0095] After alarm light 8 is activated, the system enters a 10-minute delay waiting phase. If maintenance personnel manually operate during the delay period, such as pressing alarm switch 14 to turn it off or intervening remotely via server commands, alarm light 8 will stop, but the delay timer will still be maintained, and the system will automatically drain water when the time is up.

[0096] If no one intervenes, the data processing device 111 will send a start signal to the water pump switch 13 after 10 minutes to automatically drain the water. At this time, the alarm light 8 will continue to work until the water level drops below the preset alarm threshold. Then, the data processing device 111 will send a stop signal, the alarm light 8 will automatically turn off, and the system will return to the monitoring state.

[0097] Electrical switches are core components of the high-voltage control system in flood control terminals. Encased in a waterproof housing 11, they are suitable for high-humidity / water immersion scenarios in substation flood control, ensuring electrical safety and equipment reliability. In substation flood control scenarios, flood control terminals may face rain splashes and short-term water immersion. If the contacts and terminals of the electrical switches are exposed, water can cause short circuits, leading to switch burnout, equipment power outages, and even electric shock risks. The waterproof housing 11, through its sealed design, completely isolates external water, ensuring the switches operate in a dry environment.

[0098] The water pump switch 13 is a black knob with two adjustable positions. The black knob is connected to the power supply of the water pump 32, and the water pump 32 can be manually turned on and off by adjusting the knob's position. In case of automatic drainage failure, the operator can also manually press the water pump 32 switch to start drainage.

[0099] The alarm switch 14 is a black knob with two adjustable positions. The black knob is connected to the power supply of the alarm light 8. The alarm light 8 can be manually turned on and off by adjusting the knob's position. After the staff understands the alarm situation, it can be used to clear the alarm.

[0100] The lighting switch 15 is a black knob with two adjustable positions. The black knob is connected to the power supply of the searchlight 4, and the searchlight 4 can be manually turned on and off by adjusting the knob's position. The manual control design of the searchlight 4 allows the searchlight 4 to be turned off when the flood control terminal is in a dark environment but not in operation.

[0101] The waterproof housing 11 is equipped with corresponding switches for independent functional components, which can be turned on and off as needed to avoid functional interference. If a switch fails, such as the lighting switch 15, only the function of the searchlight 4 will be affected, and the normal operation of the water pump 32 and the alarm light 8 will not be affected. This avoids the paralysis of the entire flood control terminal due to the failure of a single switch, which is in line with the flood control system.

[0102] The electrical switch is designed to support both automatic and manual control logic, and includes a manual / automatic switch 17 that allows for flexible switching between manual and automatic modes. It can be controlled automatically by the system, with the data processing device 111 triggering the switch; or it can be operated by on-site personnel using the manual / automatic switch 17 to enter manual mode.

[0103] In manual mode, the water pump 32 is directly driven by the water pump switch 13 to perform the pumping action. The operation of the water pump 32 is not affected or constrained by the detection parameters of the liquid level sensor 2. Even without connecting the liquid level sensor 2, the water pump can be started and stopped by the electrical switch.

[0104] The emergency stop switch 16 is a large, protruding, mushroom-shaped red button. It employs a mechanical hard-cut design, independent of the software logic of the data processing device 111. Even in the event of a software malfunction, pressing the emergency stop switch 16 will still effectively cut off the power. The emergency stop switch 16 is a safety redundancy switch, designed independently with the highest priority. It can directly cut off the main power supply in an emergency, preventing other switches from being accidentally triggered and causing danger.

[0105] Emergency stop switch 16 is connected to the power bus and directly cuts off the power supply to the power bus. All devices that rely on the bus for power supply will immediately stop working and achieve one-button emergency stop to prevent the danger from escalating. For example, if the water pump 32 jams or leaks water, causing the motor to overheat and catch fire, or if the searchlight 4 short-circuits and leaks electricity, pressing the emergency stop switch 16 can instantly cut off the power supply to all devices, preventing accidents such as electric shock and fire.

[0106] A green power indicator light 18 is located next to the emergency stop switch 16. The power indicator light 18 illuminates when the main power is switched on. The power indicator light 18 provides direct feedback that the equipment's power circuit is connected. During the troubleshooting phase, the illumination of the power indicator light 18 can also help determine if there is an open circuit in the power input circuit, thus narrowing down the scope of troubleshooting.

[0107] As an optional solution, the flood control terminal also includes a touch screen 9; the touch screen 9 is used to display flood control data and set relevant adjustment data for the flood control terminal.

[0108] The touch display 9 can be equipped with an industrial HMI touchscreen, which has built-in dedicated configuration software that allows for the design of multiple function pages. The industrial HMI touchscreen can adapt to the humid, dusty, and vibrating conditions of outdoor flood control stations in substations, and can communicate directly with the data processing equipment and servers of the flood control terminal to achieve real-time page data updates.

[0109] The touchscreen display 9's interface includes system time, function page names, page navigation bar, and function pages.

[0110] The top of the display shows the current system time, a timestamp used for synchronizing data records. The left side of the display shows the names of the function pages. The bottom of the display is a navigation bar containing multiple function pages built into the touchscreen 9, which can be selected via touch. These function pages include real-time data, alarm logs, historical data, parameter settings, and remote upgrade.

[0111] like Figure 3As shown, the real-time data page displays liquid level, light intensity, and alarm status, as well as status indicator lights for the automatic / manual switch 17, water pump switch 13, lighting switch 15, alarm status, and network connection. When the status indicator light for the automatic / manual switch 17 is lit, it indicates that the flood control terminal is in automatic mode; when the status indicator light for the water pump switch 13 is lit, it indicates that the water pump is currently running; when the status indicator light for the lighting switch 15 is lit, it indicates that the searchlight 4 is currently lit; when the alarm status indicator light is lit, it indicates that the water level has reached the preset alarm threshold; and when the network connection status indicator light is lit, it indicates that the flood control terminal is communicating with the server.

[0112] The real-time data page displaying liquid level, light intensity, and alarm status allows staff to quickly grasp the current flood situation and assess the on-site environment. Status indicator lights allow operators to understand the equipment's operating status. Combined with liquid level and light intensity data, flood control terminals can be controlled in real-time and efficiently via electrical switches and page navigation at the flood control site, achieving a highly efficient flood control response.

[0113] like Figure 4 As shown, the alarm log page displays alarm values ​​for liquid levels at different times. The alarm log page contains four columns: date, time, object name, and alarm value, used to record specific information for each alarm. The date and time indicate the precise time the alarm was triggered; the object name clearly identifies the device that triggered the alarm; and the alarm value records the specific liquid level value at the time the alarm was triggered.

[0114] The alarm log page can be used to provide staff with historical flood control data. If the alarm status light of the flood control terminal gives a false alarm, the alarm value can be checked against the preset threshold through the alarm log to determine whether the problem lies in parameter settings or sensor malfunction. Furthermore, based on historical alarm logs, flood control strategies such as water level thresholds and the deployment location of flood control terminals can be optimized to improve the accuracy of the next flood control response.

[0115] like Figure 5 As shown, the historical data page displays historical data in a table format, including serial number, time, liquid level, light intensity, signal quality, and connection status. The flood control terminal stores historical data every 20 minutes. The historical data page also includes an operation button area, which contains buttons for page turning, time setting, clearing records, and one-click export, supporting data querying, management, and export.

[0116] The page turning buttons include a triangle button, an arrow button, and a refresh button. Use the triangle button to scroll up and down, and the arrow button to navigate to the first or last page. If page turning is choppy, use the refresh button to refresh the page. The time setting button allows you to select the desired historical date and filter historical data for a specific date, facilitating targeted verification of the entire flood event's data. The clear record button clears all historical data records. The one-click export button saves historical data to a USB drive for later flood control work review, data report compilation, and as an archive of equipment operating status.

[0117] The historical data page allows users to view data such as liquid level height and light intensity at different times, summarizing patterns in flood conditions and observing the stability of signals and connection status. If subsequent issues such as liquid level sensor malfunctions or network anomalies occur, the historical data can be used to trace the time of the fault, aiding in troubleshooting.

[0118] like Figure 6 As shown, the parameter setting page includes flood control parameter configuration items and system information display items. Flood control parameters include: zero-point offset, used to calibrate the reference value of liquid level sensor 2 to ensure the accuracy of liquid level measurement; high-level alarm value, used to set the threshold value for triggering a high-water-level alarm, when which the system will issue a warning; low-level release value, used to set the threshold value for releasing the high-water-level alarm, when the water level falls below this value, the alarm status is automatically released; and light-on lumen, used to set the light intensity threshold for automatic activation of searchlight 4, when the on-site light is below this value, the lighting function is automatically activated.

[0119] The system information displayed includes: card number, which is the number of the device's communication SIM card and is used for network connection identification; CSQ value, which is the signal quality index and reflects the network communication strength of the device; IMEI, which is the device's globally unique identification code and is used for the identification of communication devices; and device number, which is the unique device code of the flood control terminal and is used to distinguish flood control terminals at different sites.

[0120] like Figure 7 As shown, the remote upgrade page includes a communication parameter configuration area and a communication status function area. The communication parameter configuration area contains information such as server address, port number, username, and password. These are key parameters for establishing a network connection between the flood control terminal and the server, ensuring that the flood control terminal can transmit data to the server and receive remote commands. The device ID and key are the device's authentication information, ensuring communication security. Longitude and latitude are used to mark the terminal's deployment location. A green communication status indicator shows that the flood control terminal has successfully connected to the server and is in communication mode. A QR code is provided below, which can be used to associate the device's configuration information or access the cloud management portal for quick scanning and binding, and viewing device details.

[0121] By configuring communication parameters, the flood control terminal can be connected to the Internet of Things platform, supporting remote firmware upgrades, data collection, and command issuance; the communication status identification and testing functions can quickly verify network connectivity, ensuring the reliability of remote operation and maintenance of equipment, and are suitable for unified management scenarios of industrial equipment such as distributed flood control terminals.

[0122] In summary, the touchscreen display 9 enables real-time monitoring of flood conditions and equipment status through a real-time data page, personalized configuration through a parameter setting page, and the retention of risk points and support for flood situation review through alarm record and historical data pages. The remote upgrade page enables centralized cloud-based operation and maintenance of equipment. Ultimately, this transforms flood control work from a passive on-site response to proactive full-cycle management, ensuring both precise and efficient on-site operations and enhancing multi-site risk management and remote control capabilities. It effectively solves the problems of untimely flood drainage and low flood control efficiency in substations.

[0123] According to another aspect of the present invention, an automated online collaborative flood control method for substation flood control is also provided, such as... Figure 8 As shown, it includes the following steps:

[0124] Step S101: Based on the substation water network data and meteorological environment data, determine the flood control stations of the substation water network and the flood control terminal layout scheme for each flood control station.

[0125] Step S102: The flood control terminal is scheduled according to the layout scheme. The movable body 1 of the flood control terminal is arranged at the corresponding flood control station. The movable body 1 includes a waterproof shell 11 and a mobile device 12 installed on the waterproof shell 11. The waterproof shell 11 is also equipped with a data processing device 111 and a communication device 112. The data processing device 111 is used to receive and process flood control data, and the communication device 112 is used to connect with the cloud collaborative system.

[0126] Step S103: Real-time monitoring of flood control data through the liquid level sensor 2 of the flood control terminal. The liquid level sensor 2 is connected to the data processing device 111 via a data cable. When in use, the liquid level sensor 2 is led out from the data processing device 111 and placed in the water of the flood control station of the substation to be monitored.

[0127] Step S104: Based on flood control data, substation water network data, and meteorological environment data, control the pumping component 3 of the flood control terminal to pump water for flood control. The pumping component 3 includes a water pump 32, a pumping pipe 31, and a drainage pipe 33. The water pump 32 is installed inside the waterproof housing 11. One end of the pumping pipe 31 is placed in the water at the substation flood control site, and the other end is connected to the water pump 32. One end of the drainage pipe 33 is placed on the water pump 32, and the other end of the drainage pipe 33 is placed at the drainage point.

[0128] In step S101, water network data can be manually entered through the server's backend management system, or the water network topology can be automatically parsed by importing CAD or BIM model files; alternatively, flow sensors, pressure sensors, and opening sensors can be installed at pipeline nodes, pumping stations, and gates and connected to the server via the substation's industrial Ethernet to update the water network data in real time at a frequency of once per minute.

[0129] Substation water network data can be used to prioritize dispatching flood control terminals to water accumulation points based on the pipe network confluence path, avoiding conflicts between pumping pipelines and the pipe network; the optimal drainage point can be selected according to the carrying capacity of the drainage pipe network to avoid backflow in the pipe network caused by drainage; and the water flow diffusion speed can also be simulated through the pipe network topology to pre-dispatch terminals to block the diffusion path.

[0130] Meteorological data is valuable for predicting rainfall intensity in advance. Waiting until water levels exceed warning levels before taking action may lead to a rapid rise in water levels due to continued rainfall, causing the optimal drainage opportunity to be missed. Based on the predicted rainfall intensity, flood control terminals can be deployed to high-risk areas in advance for preventative drainage, such as by deploying them to historically significant rainfall points. If the weather forecast indicates no continued rainfall, pumping power can be appropriately reduced to conserve energy.

[0131] Based on water network data and meteorological environmental data, a two-dimensional risk matrix can be constructed, which includes the water network's carrying capacity and the intensity of meteorological rainfall, to calculate the waterlogging risk value for each region. For example, the risk value is calculated as follows: Risk Value = (Rainfall Intensity × Rainfall Duration ÷ Pipeline Design Flow Rate) × Topographic Weight × Historical Waterlogging Frequency Weight. The topographic weight is set according to the region's altitude; the historical waterlogging frequency weight is assigned based on the number of waterlogging events per year.

[0132] The server has a built-in flood control risk assessment model that can use fuzzy comprehensive evaluation or machine learning models, such as LSTM (Long Short-Term Memory) networks, trained on historical data to improve prediction accuracy. Based on the calculated risk value and the status of flood control terminals, the server generates different flood control terminal layout schemes for flood control sites in different risk areas.

[0133] For example, in extremely high-risk areas, 2 to 3 flood control terminals can be deployed to form a pumping cluster. One flood control terminal can be positioned at the lowest point of water accumulation as the main pumping equipment, while 1 to 2 other flood control terminals can be positioned at the pipeline inlet to assist in drainage and prevent backflow. In medium-risk areas with a low probability of water accumulation, one flood control terminal can be deployed near the area where water accumulation may occur, and kept in standby mode.

[0134] In step S102, the server generates the optimal movement path for each flood control terminal based on the layout scheme and substation terrain data, using a path planning algorithm to avoid obstacles such as equipment foundations and cable trenches. The dispatch instructions issued by the server include the target site coordinates and movement speed.

[0135] The server sends dispatch instructions to the corresponding flood control terminal via LoRa communication device 112; after parsing the instructions, the flood control terminal data processing device 111 controls the mobile device 12 to start. The current position is fed back in real time via GPS (Global Positioning System), compared with the target coordinates, and the movement direction is dynamically adjusted.

[0136] After the flood control terminal arrives at the target site, it uses GPS positioning verification to ensure that the deviation from the target coordinates is less than 5cm. The self-locking function of the mobile device 12 is activated to prevent displacement of the terminal due to water flow impact or vibration. Once deployed, the terminal sends a deployment-ready signal to the server via communication device 112, simultaneously uploading its current location and device status.

[0137] In step S103, after the terminal is deployed, the operator or automatic control mechanism leads the liquid level sensor 2 out of the waterproof housing 11. The sensor is connected to the data processing device 111 via a data cable. The flexible section length is preset and can be adjusted according to the water depth at the station. When the sensor is deployed, the probe must be completely submerged in water, with a depth greater than 10cm, to avoid measurement distortion caused by water surface fluctuations. It should also maintain a distance of more than 5cm from the pumping pipe 31 to avoid water flow impact affecting data accuracy.

[0138] Liquid level sensor 2 collects water level depth data in real time. The software reads the signal from liquid level sensor 2 once per second by default. The collected raw data is filtered to remove abnormal fluctuations, such as instantaneous peaks caused by slight sensor vibration, to ensure the accuracy of the water level data. The processed water level data is converted into a digital signal, which is displayed in real time on the liquid level display panel and also transmitted to the site server via communication device 112 as flood control data. The server continuously compares the real-time water level with the preset alarm threshold to determine whether to trigger an early warning command.

[0139] The processed flood control data is uploaded to the server and simultaneously cached locally in data processing device 111. A historical record interface can be set on the liquid level display panel to view the liquid level monitoring values ​​during automatic operation. Data is stored every 10 minutes by default, but can be viewed by date. Past alarm times and details can be viewed through the alarm record interface.

[0140] The server receives flood control data uploaded by terminals and, combined with preset substation water network data and meteorological environmental data, updates the site risk level to safe, early warning, emergency, or extreme using a fuzzy comprehensive evaluation method. For example, if the real-time liquid level exceeds the preset emergency warning threshold, the real-time flow of the pipeline is close to the design capacity of the main pipeline, and the expected rainfall in the next hour is heavy, the risk level is determined to be extreme. The server can issue commands to suspend power supply to non-core equipment in the substation and coordinate with fire departments or municipal drainage departments for support.

[0141] Simultaneously, the server sends control commands, such as starting water pump 32, to the terminal via communication device 112. After parsing the commands, the flood control terminal data processing device 111 controls the electrical switch to turn on water pump 32, thus starting water pump 32. During the drainage process, the server receives liquid level data in real time. If the rate of liquid level drop after pumping is less than expected, it dispatches more flood control terminals for support or adjusts the drainage path.

[0142] When the liquid level drops to the preset safety warning threshold, and the weather forecast indicates no continuous rainfall and the pipeline flow returns to normal, the server issues a shutdown command. If the emergency stop switch 16 signal is detected, the power supply to the water pump 32 is immediately cut off, and pumping stops.

[0143] In summary, this flood control method achieves proactive prevention and efficient response to flooding at substations through a comprehensive design encompassing data-driven flood control site selection, differentiated deployment of flood control terminals, automated dispatching of these terminals, precise monitoring, and pumping flood control. Substation water network data and meteorological environmental data ensure the accuracy of flood control site selection; mobile flood control terminals address deployment flexibility; and multi-data fusion control ensures pumping efficiency and safety. Ultimately, this method solves the problems of untimely drainage and low flood control efficiency at substations.

[0144] As an optional approach, based on substation water network data and meteorological environmental data, the flood control stations of the substation water network and the layout scheme of flood control terminals for each flood control station are determined. This includes: constructing a spatiotemporal map based on multi-source data of substation water network data and meteorological environmental data, combined with a substation map. The spatiotemporal map includes multiple flood control units, and each flood control unit has at least one identical flood control station. Based on the neural field model corresponding to the flood control unit, the multi-source data is input to obtain the predicted flood data of the flood control unit in the target time period. The predicted flood data includes water volume and flow velocity. Based on the predicted flood data, the locations of the flood control units where flooding is about to occur are determined as flood control stations. Based on the predicted flood data corresponding to the flood control stations, the number of flood control terminals is determined.

[0145] When constructing the spatiotemporal map, the substation map is used as a basis. The drainage network topology and low-lying area coordinates in the water network data are converted into spatial vector data using GIS technology. All spatial data are then mapped to the same coordinate system, for example, using the local plane coordinate system of the substation as the unified coordinate system.

[0146] Rainfall forecasts for the next 24 hours are preprocessed in 15-minute time slices, while real-time flow and water level data from the water network are preprocessed in 1-minute time slices. Data of different frequencies, such as 15-minute rainfall and 1-minute network flow, are interpolated to a uniform time granularity, such as 5 minutes per slice. Qualitative data are converted into quantitative weights, such as a weight of 0.2 for historical flooding occurring once per year and 0.8 for flooding occurring three times per year.

[0147] The substation map is divided into 5m×5m grids as the smallest spatial units. The grid size can be adjusted according to the scale of the substation. Each grid serves as a spatial node in the spatiotemporal map. A time axis is added to each spatial node, such as one time step every 5 minutes, forming a two-dimensional matrix of spatial nodes and time steps. Each spatial node-time step corresponds to a set of attribute data, including: grid elevation, whether it is a pipeline node, whether it is a low-lying area, historical water accumulation weight; predicted rainfall, pipeline flow, and water level change rate for that time step.

[0148] Spatial edges establish spatial relationships between adjacent grid cells in the top, bottom, left, and right directions, with a weight of distance, reflecting the spatial correlation of water diffusion. Temporal edges establish temporal relationships between different time steps within the same grid cell, with a weight of time difference, reflecting the temporal continuity of the data. Water network edges establish water network relationships between pipe network nodes, with a weight of pipe diameter or pipe length, reflecting the resistance to water flow transmission.

[0149] The spatiotemporal diagram is a digital model that integrates the spatial topology of a substation, the temporal dimension, and flood control data. Spatial edges, temporal edges, and water network edges respectively cover the three dimensions of spatial diffusion, temporal evolution, and engineering rules. Weights are the quantitative carriers of these logics. The three dimensions together construct a spatiotemporal diagram that conforms to physical laws and closely reflects the actual scenario.

[0150] Flood control units are divided into one flood control unit based on the same drainage pipe network system, and areas affected by the same meteorological system and with consistent topographic features are divided into another flood control unit.

[0151] The reason why a single flood control unit has at least one identical flood control station is that accumulated water within the unit will spread along the pipe network or terrain. It is unnecessary to set up a separate station in each grid; a single flood control station at a key transmission node is sufficient to cover the entire unit's flood monitoring and drainage needs. Setting up a station in each grid would lead to redundancy of flood control terminals, increasing costs. A shared station can cover multiple risk points and balance coverage through the mobility of flood control terminals. Sharing a core station within the same unit can serve as a hub for flood control terminals, facilitating coordinated drainage when multiple flood control terminals are connected online.

[0152] Different flood control units have different pipeline topologies, terrain features, and historical flood patterns. Training a neural field model separately for each flood control unit allows the model to adapt to unique flood evolution patterns and improves prediction accuracy. The neural field model can employ a spatiotemporal convolutional neural network.

[0153] The system obtains predicted flood data for the target time period using real-time spatiotemporal map data from current flood control units, including the latest rainfall, real-time pipeline flow, and terrain attributes. A neural field model extracts spatiotemporal features of the target time period through spatiotemporal convolutional layers. An attention mechanism, based on regional risk values, outputs predicted water volume and flow velocity for each grid-time step within the next 24 hours.

[0154] The server sets flow and velocity thresholds based on the safety boundary of water depth in substation equipment and the carrying capacity of the pipeline network. When the water flow exceeds the flow threshold or the velocity exceeds the velocity threshold, and the duration is greater than one time step, the location is determined to be a location where a flood is about to occur. If multiple adjacent grids trigger the threshold, they are considered as a flood area, and the geometric center of this area or the grid with the largest water accumulation is taken as the flood control station.

[0155] The number of flood control terminals to be deployed is determined based on the predicted flood data corresponding to the flood control stations. Since predicted flood data directly reflects the scale, development trend, and difficulty of handling the flood situation at each station, determining the deployment quantity based on this data allows for on-demand configuration. This avoids insufficient terminals leading to drainage capacity lagging behind the flood growth rate, and also prevents resource waste caused by terminal redundancy. Furthermore, by incorporating the risk level in the predicted data, the number of flood control terminals can be configured differently, with reserve redundancy to ensure that flood control resources are tilted towards areas of high demand. Ultimately, this achieves the goal of rapidly handling various flood situations with minimal terminal investment, ensuring the timeliness and effectiveness of substation flood control.

[0156] As an optional solution, based on flood control data, substation water network data, and meteorological environment data, the pumping component 3 of the flood control terminal is controlled to pump water for flood control. This includes: comparing the flood control data of the flood control station with the corresponding predicted flood data to determine the prediction reliability of the flood control station; if the prediction reliability reaches a preset reliability threshold, updating the substation water network data based on the flood control data, and calculating the predicted flood data for the next period based on the updated substation water network data and meteorological environment data; if the predicted flood data for the next period exceeds a preset warning threshold, controlling the pumping component 3 of the flood control terminal to pump water for flood control based on the predicted flood data; and if the prediction reliability does not reach the preset reliability threshold, dispatching manual flood control.

[0157] The reliability is determined by quantitatively comparing the flood control data collected in real time by the flood control terminal with the predicted flood data output by the neural field model, and calculating evaluation indicators. First, the absolute error and the relative error between the actual and predicted values ​​are calculated, and the consistency of their changing trends is verified. If the relative error is less than the preset error value, the absolute error is less than the safety margin value, and the trend consistency meets the matching of three consecutive time steps, then the prediction reliability is determined to have reached the preset reliability threshold. Conversely, if the error exceeds the preset error value or the trend completely deviates, the reliability is considered to have failed.

[0158] When the prediction reliability meets the standard, it indicates that the real-time flood control data can accurately reflect the current operating status of the water network. At this point, the dynamic data in the substation water network is replaced with real-time data, such as updating the original water network data model with real-time pipeline flow and actual liquid level, forming updated water network data that fits the actual operating conditions. Subsequently, this updated water network data and the latest meteorological environmental data are used as inputs and then input again into the neural field model of the corresponding flood control unit. Through the model's spatiotemporal convolution and attention mechanisms, combined with the verified flood situation evolution patterns, the predicted flood data for the next period is recalculated, achieving a closed-loop optimization of real-time feedback, model iteration, and accurate prediction.

[0159] If the predicted data for the next period exceeds the preset warning threshold, it indicates that a flood exceeding the safe range is imminent. At this point, the pumping unit 3 is controlled based on the predicted data to achieve preventative flood control. On one hand, pumping operations can be initiated in advance, utilizing the pumping capacity of the flood control terminal to match the flood growth trend, avoiding delays caused by responding only after the water level reaches a dangerous level. On the other hand, by optimizing the pumping path and intensity based on updated water network data, backflow or pipeline overload can be avoided, ensuring maximum pumping efficiency and preventing the threat of flooding to substation equipment from the source, thus better guaranteeing flood control safety.

[0160] If the forecast reliability fails to meet standards, it indicates a significant deviation between the real-time flood situation and the forecast results. In such cases, the automated control system may make misjudgments due to data discrepancies, or even experience control failure. Manual flood control dispatch can accurately grasp the actual flood situation through on-site surveys, such as checking for pipe blockages and confirming the true extent and depth of water accumulation. Personnel can compensate for the automation system's inability to adapt to sudden abnormal scenarios by taking flexible and targeted measures, such as temporarily adding drainage equipment, clearing obstacles, and manually adjusting terminal positions and pumping strategies. Ultimately, this forms a dual guarantee of efficient automated response and manual emergency backup, preventing the flood situation from escalating due to forecast deviations and ensuring the reliability of substation flood control.

[0161] The automated online collaborative flood control method for substations provided by the embodiments of this invention utilizes multi-source data fusion and neural field modeling to construct a spatiotemporal map, accurately predicting the location, volume, and spread trend of flood conditions. It iteratively optimizes the prediction results based on real-time flood control data, enabling preventative drainage by activating pumping units 3 in advance, thus addressing the problem of delayed drainage. Simultaneously, it quantifies the number of terminals deployed using predicted data, flexibly scheduling mobile flood control terminals and coordinating across units to optimize pumping power and routes, avoiding resource misallocation and pipeline overload, and improving flood control efficiency. Furthermore, it allows for manual backup when prediction reliability is insufficient, forming a dual support system of automated precision handling and manual emergency response, thereby solving the problems of untimely flood drainage and low flood control efficiency in substations.
