Description

Technical Field

[0001] This invention belongs to the technical field of water conservancy monitoring equipment, and in particular, it is a method for automatic early warning of rainfall and water conditions using an intelligent water conservancy PTZ camera. Background Technology

[0002] Digital water conservancy refers to a development strategy and process that is guided by the concept of sustainable development, takes harmony between humans and water as the ultimate goal, and adopts a series of high-tech means with information technology at its core to upgrade and transform the water conservancy industry in order to comprehensively improve the efficiency and effectiveness of water-related activities.

[0003] First, digital water conservancy is a high-tech development strategy for the water conservancy industry based on the concept of sustainable development. After several years of theoretical research and exploration, the water conservancy industry has formed a relatively systematic theoretical framework for sustainable development. The rapid development of high technologies, with information technology at its core, has made comprehensive technological upgrading possible for the water conservancy industry. Flood control and disaster reduction, water resource monitoring and management, comprehensive water environment management, the design and construction of large-scale water conservancy projects, and the comprehensive management of large and medium-sized irrigation areas all urgently require technological transformation using a series of high technologies such as computer technology, communication network technology, microelectronics technology, computer-aided design technology, and 3S technology (remote sensing, geographic information systems, and global positioning systems). The water conservancy industry needs to stand at the forefront of current science and technology, combine it with the application needs of the water conservancy industry, and propose a relatively systematic technological development strategy to provide operable technological content for the concept of sustainable water conservancy.

[0004] Secondly, digital water management is a historical process of technological upgrading within the water conservancy industry. Clearly, digital water management won't happen overnight; it requires extensive research in both basic and applied technologies. This involves not only clearly understanding the tasks of water conservancy development, accurately identifying water problems in a specific region, analyzing application needs related to solving these problems, streamlining information flows in water conservancy operations, and finding entry points to improve the efficiency and effectiveness of water-related activities, but also keeping abreast of the latest advancements in information technology, researching solutions that combine various information technologies with the needs of the water conservancy industry, and developing and deploying various water conservancy business application information systems. These are all essential processes for implementing a digital water management strategy. Digital water management and water conservancy informatization share some semantic similarities; digital water management is essentially a new historical development strategy for water conservancy informatization. The difference lies in the fact that water conservancy informatization encompasses the entire historical process of computer and information technology applications within the water conservancy industry, while digital water management, based on a sustainable development approach to water management, emerged around 2000 with the advent of new water management strategies and the large-scale application of digital circuit technology in the communications industry.

[0005] Third, the cutting-edge research area of ​​digital water conservancy is the digital watershed. Although Digital Earth is an important technological background for the proposal of digital water conservancy, its natural extension is not digital water conservancy, but rather the digital watershed. The digital watershed is a part of digital water conservancy. Implementing the digital water conservancy strategy requires understanding the laws of water cycle movement and identifying water problems, and the digital watershed is precisely a powerful tool for understanding the laws of water cycle movement and water problems within a watershed, using the watershed as the research unit. The digital watershed naturally adopts the spatial geographic information framework of Digital Earth, uses remote automatic measurement and control technology to collect various watershed-related water information, employs mathematical models to simulate the watershed water cycle (including natural and artificial cycles), and establishes a three-dimensional watershed water information platform. This provides a basis for solving watershed water problems and for macroeconomic decision-making, constituting the most active cutting-edge research area of ​​digital water conservancy.

[0006] "Digital water conservancy" is a high-tech development strategy for the water conservancy industry based on the concept of sustainable development. Video surveillance technology is an important monitoring method. It mainly involves deploying video monitoring points in engineering areas such as sluice gates, river channels, and reservoirs. It can monitor river flow, reservoir water volume, and local rainfall in real time, and promptly monitor potential or ongoing disasters, emergencies, floods, and droughts, and send out alarms and trigger alerts in real time. This allows for quick understanding of the actual situation on site and the implementation of corresponding preventive and remedial measures to minimize the harm to people's lives and property caused by floods. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and propose an intelligent water conservancy PTZ camera automatic early warning method for rainfall and water conditions. When rainfall occurs and the monitoring of rainfall and water level occurs, the PTZ camera can automatically predict the rainfall amount, and automatically link the warning lights, audible alarms, and output external alarm devices to prompt relevant personnel to take appropriate measures in a timely manner to reduce the losses caused by flood disasters.

[0008] The technical problem solved by this invention is achieved through the following technical solution: An automatic early warning method for rainfall conditions using intelligent water conservancy PTZ cameras includes multiple rain gauges, multiple intelligent water conservancy PTZ cameras, and a water conservancy platform. Each rain gauge is connected to a corresponding intelligent water conservancy PTZ camera. Multiple rain gauges and their corresponding intelligent water conservancy PTZ cameras are installed at different locations. Each intelligent water conservancy PTZ camera is connected to the water conservancy platform. The rain gauges are used to receive rainwater, and the intelligent water conservancy PTZ cameras are used to collect the rainwater signals from the rain gauges, perform calculations, and generate alarm signals. The water conservancy platform is used to statistically analyze the data transmitted by the multiple intelligent water conservancy PTZ cameras and the alarm signals.

[0009] Furthermore, the rain gauge is used to collect rainwater, and a warning threshold is set on the rain gauge.

[0010] Furthermore, the intelligent water conservancy ball camera outputs a pulse signal switching quantity and sends it to the water conservancy platform when the water volume collected by the rain gauge reaches a predetermined value. It also transmits the collected signal change quantity to the intelligent water conservancy ball camera. At the same time, the intelligent water conservancy ball camera includes field detection and timed monitoring.

[0011] An automatic early warning method for rainfall and water conditions using an intelligent water conservancy PTZ camera includes the following steps: Step 1: The intelligent water-sensing ball is connected to the rain gauge via a signal cable, and the intelligent water-sensing ball collects relevant information about the rainwater in the rain gauge. Step 2: The intelligent water conservancy sphere camera determines whether to perform session monitoring or timed monitoring based on the settings of the water conservancy platform. If it is session monitoring, it calculates the cumulative change value of a single session's rainfall; otherwise, it calculates the cumulative change over a specified time period. Step 3: The intelligent water conservancy sphere camera detects whether the cumulative rainfall value of the rain gauge has reached the set warning threshold. If the set warning threshold is reached, an alarm message is generated and sent to the water conservancy platform. At the same time, the alarm light, alarm sound, and related alarm devices of the port output are automatically linked, and the rainfall situation at that time is recorded. Step 4: The water conservancy platform records the rainfall conditions at each location.

[0012] Furthermore, in step 1, the output pulse signal of the rain gauge is automatically accumulated and recorded by the PTZ camera as the single increase amount ΔH.

[0013] Furthermore, the method for calculating the cumulative change in single-event rainfall in step 2 is as follows: H R =(1+2+3...N)*△H Among them, H R The value represents the rainfall in a single event, ΔH represents the increase in the change of the acquired signal in a single event, and N represents the number of detections.

[0014] Furthermore, the method for calculating the cumulative change within the specified time period in step 2 is as follows: H R’= H R1 +H R2 ...H Rn Among them, H R’ H represents the cumulative change over a specified time period. R1 =(1+2+3...N)*△H, H R2 =(1+2+3...N)*△H, H Rn Let denot be the rainfall amount of the nth event, ΔH be the single increase in the change of the collected signal, and N be the number of detections.

[0015] Furthermore, the specific implementation method of step 3 is as follows: set a rainfall warning threshold W. R When the cumulative rainfall value detected by the intelligent water conservancy sphere meter reaches W RIt will issue an alarm when the water level reaches the warning value set by S2, generate an alarm message and report it to the outside, and at the same time activate related alarm devices such as alarm lights, alarm sounds, and port output peripherals.

[0016] The advantages and positive effects of this invention are: This invention comprises multiple rain gauges, multiple intelligent water-sensor cameras, and a water conservancy platform. Each rain gauge is connected to a corresponding intelligent water-sensor camera. The multiple rain gauges and their corresponding intelligent water-sensor cameras are installed at different locations. Each intelligent water-sensor camera is connected to the water conservancy platform. The rain gauges receive rainwater, and the intelligent water-sensor cameras collect the rainwater signals from the rain gauges, perform calculations, and generate alarm signals. The water conservancy platform is used to analyze the data transmitted by the multiple intelligent water-sensor cameras and the alarm signals. This invention can automatically predict rainfall when monitoring rainfall and water levels. The water-sensor cameras will automatically activate warning lights, audible alarms, and output external alarm devices to alert relevant personnel to take timely measures and reduce losses caused by floods.

[0017] Figure 1 This is a flowchart of the present invention. Detailed Implementation

[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] A method for automatic early warning of rainfall and water conditions using intelligent water conservancy PTZ cameras, such as... Figure 1 As shown, the system includes multiple rain gauges, multiple intelligent water sphere cameras, and a water conservancy platform. Each rain gauge is connected to a corresponding intelligent water sphere camera. The multiple rain gauges and their corresponding intelligent water sphere cameras are installed at different locations. The multiple intelligent water sphere cameras are connected to the water conservancy platform. The rain gauges are used to receive rainwater, and the intelligent water sphere cameras are used to collect the rainwater signals from the rain gauges, perform calculations, and generate alarm signals. The water conservancy platform is used to collect and analyze the data transmitted by the multiple intelligent water sphere cameras and the alarm signals.

[0020] Rain gauges are used to collect rainwater, and they are also equipped with warning thresholds. When the rain gauge collects a predetermined amount of water, the intelligent water sphere camera outputs a pulse signal and sends it to the water conservancy platform. It also transmits the changes in the collected signal back to the intelligent water sphere camera. The intelligent water sphere camera includes both field detection and timed monitoring.

[0021] An automatic early warning method for rainfall and water conditions using an intelligent water conservancy PTZ camera includes the following steps: Step 1: The intelligent water-sensing ball is connected to the rain gauge via a signal cable, and the intelligent water-sensing ball collects relevant information about the rainwater in the rain gauge.

[0022] The output pulse signal of the rainwater detection in the rain gauge in step 1 is automatically accumulated and recorded by the PTZ camera as the single increase amount △H.

[0023] Step 2: The intelligent water conservancy sphere camera determines whether to perform session monitoring or timed monitoring based on the settings of the water conservancy platform. If it is session monitoring, it calculates the cumulative change value of a single session's rainfall; otherwise, it calculates the cumulative change over a specified time period.

[0024] The method for calculating the cumulative change in a single rainfall event is as follows: H R =(1+2+3...N)*△H Among them, H R The value represents the rainfall in a single event, ΔH represents the increase in the change of the acquired signal in a single event, and N represents the number of detections.

[0025] The method for calculating the cumulative change over a specified time period is as follows: H R’= H R1 +H R2 ...H Rn Among them, H R’ H represents the cumulative change over a specified time period. R1 =(1+2+3...N)*△H, H R2 =(1+2+3...N)*△H, H Rn Let denot be the rainfall amount of the nth event, ΔH be the single increase in the change of the collected signal, and N be the number of detections.

[0026] Step 3: The intelligent water conservancy sphere camera detects whether the cumulative rainfall value of the rain gauge has reached the set warning threshold. If the set warning threshold is reached, an alarm message is generated and sent to the water conservancy platform. At the same time, the alarm light, alarm sound, and relevant alarm devices of the port output are automatically linked, and the rainfall situation at that time is recorded.

[0027] Set rainfall warning threshold W R When the cumulative rainfall value detected by the intelligent water conservancy sphere meter reaches W R It will issue an alarm when the water level reaches the warning value set by S2, generate an alarm message and report it to the outside, and at the same time activate related alarm devices such as alarm lights, alarm sounds, and port output peripherals.

[0028] Step 4: The water conservancy platform records the rainfall conditions at each location.

[0029] The effectiveness of the present invention has been verified by monitoring a certain rainfall event, based on the aforementioned intelligent water conservancy sphere camera automatic early warning method.

[0030] Step S1: Set the single rainfall step size ΔH = 1mm.

[0031] Step S2: Set the rainfall warning threshold W R =20mm.

[0032] Step S3: Set up water level monitoring, water level Hw =300mm, water level warning W h =320mm.

[0033] Step S4: If the pulse signal switching quantity is collected 30 times, then the cumulative rainfall H is... R =30mm.

[0034] Step S5: Cumulative Rainfall H R Exceeding the warning threshold W R If the rainfall alarm is triggered, it will be remotely uploaded to the hydrological monitoring platform, and at the same time, it will trigger relevant alarm devices such as warning lights, sirens, and port output peripherals to prompt relevant personnel to take appropriate measures in a timely manner.

[0035] Step S6: Rainfall increases by 30mm, water level increases by 30mm accordingly, H w =330mm.

[0036] Step S7: Water level H w Exceeding the warning threshold W h If the alarm is triggered, a water level alarm message will be generated and uploaded remotely to the hydrological monitoring platform. At the same time, it will trigger relevant alarm devices such as alarm lights, alarm sounds, and port output peripherals to prompt relevant personnel to take appropriate measures in a timely manner.

[0037] It should be emphasized that the embodiments described in this invention are illustrative rather than limiting. Therefore, this invention includes, but is not limited to, the embodiments described in the specific implementation. Any other implementations derived by those skilled in the art based on the technical solutions of this invention are also within the scope of protection of this invention.
