Description

Technical Field

[0001] The present invention relates to the field of earthquake, geological disaster meteorology and flood disaster prevention and mitigation technology, and in particular to an intelligent early warning and response method and platform for multiple disasters including earthquake, geological disaster meteorology and flood. Background Art

[0002] The hazards of earthquakes, geological disasters, meteorological conditions and floods are related to the earthquake intensity, geological disaster meteorological risk level and flood risk level of the target area where the disaster-bearing body is located. When the earthquake intensity is above 3 degrees, the roads, tracks and transmission lines have been significantly displaced, which will lead to road interruption, track disengagement and transmission line disconnection, causing secondary disasters such as drowning, traffic accidents, electric shock and electrical fire. In the past, when earthquakes, geological disasters, meteorological conditions and floods occurred, the shutdown of transmission lines and roads required human intervention to determine whether the emergency warning reached the emergency response level, and then notify the rescue personnel to close the electrical lines, railway and highway gates. Not only may the best time to close the gates be missed, but it is also easy to cause electric shock, fire and traffic accidents. For example, when the earthquake intensity exceeds 3 degrees, fragile roads, tracks and transmission lines will be disconnected, threatening the lives of responders. In addition, if the Internet of Things is used to close the gates alone, the wireless signal is likely to be lost when earthquakes, geological disasters, meteorological conditions and floods occur, and the emergency response of closing the gates cannot be achieved. Moreover, the existing intelligent video analysis system and sensor analog signal acquisition system are independently set up and cannot judge the disaster site conditions in combination with earthquakes, geological disasters, meteorology and floods. They can only set a unique critical value based on the intelligent identification of the displacement at the disaster site and the sensor detection value, and shut down when it exceeds the critical value. However, when earthquakes, geological disasters, meteorology and floods occur, the on-site conditions change too quickly. When the displacement at the site is detected to exceed the critical value, a large number of electric shocks and traffic accidents have already occurred. Summary of the invention

[0003] In view of the technical problems in the prior art that railways, highways and power transmission lines cannot be automatically shut down when earthquakes, geological disasters, meteorological disasters and floods occur, and railways, highways and power transmission lines near mountains and water cannot change the disaster response level according to the environment, resulting in the occurrence of secondary disasters caused by natural disasters, this application provides an intelligent early warning and response platform for multiple disasters such as earthquakes, geological disasters, meteorological disasters and floods, so as to improve the accuracy and reliability of disaster early warning response. .

[0004] In a first aspect of the present application, an intelligent early warning and response platform for multiple disasters including earthquakes, geological disasters, meteorology and floods is provided, wherein the earthquake early warning and response platform comprises:

Specifically, if the warning level signal is greater than or equal to the preset value of the seismic fortification intensity, the preset value of the geological disaster meteorological response level or the preset value of the flood response level in the target area, an emergency response instruction is issued, wherein the earthquake intensity level signal is generated and sent by the National Earthquake Monitoring Network, and the geological disaster meteorological warning level signal comes from the geological disaster meteorological system established by the land and resources authority in conjunction with the meteorological authority.

[0013] The present application provides an IoT intelligent early warning and response method and platform for earthquakes, geological disasters, meteorology and floods, which is used to solve the technical problems in the prior art that power lines and railways and highways cannot be automatically and quickly shut down during earthquakes, geological disasters, meteorology and floods, and disaster warnings cannot change the response level in combination with the dangerousness, disaster susceptibility and vulnerability of the environment in which the disaster-bearing body is located, resulting in serious secondary disasters for power lines and railways and highways.

[0014] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0015] Embodiment 1

[0016] like Figure 1 As shown, the present application provides an intelligent early warning and response early warning method for multiple disasters including earthquake, geological disaster, meteorological and flood, and the method comprises:

[0017] Step S100: The Internet of Things platform server receives earthquake intensity, geological disaster meteorology and flood warning level signals, and generates response instructions if they are greater than the preset level, wherein the earthquake intensity signal comes from the National Earthquake Monitoring Network, the geological disaster meteorology level signal comes from the geological disaster meteorology warning platform, and the flood level signal comes from the water conservancy agency warning platform; according to the danger, disaster susceptibility and vulnerability of the target area, the earthquake fortification intensity preset value, the geological disaster meteorology response level preset value and the flood response level preset value are set, and stored in the Internet of Things platform server; according to the danger, disaster susceptibility and vulnerability of the target area, the intelligent video digital signal response level preset value and the sensor analog signal response threshold preset value are set, and stored in the multi-hazard edge computing gateway. The warning signal also includes intelligent video digital signals and sensor analog signals, and if they are greater than the preset level and threshold, a shutdown instruction and an audible and visual alarm instruction are generated;

[0018] Specifically, the IoT platform server is always ready to receive data; when the National Earthquake Monitoring Network detects abnormal seismic waves, or the geological disaster meteorological early warning platform detects abnormal meteorological conditions, or the flood early warning platform detects abnormal water surface conditions, they will quickly send out multi-hazard early warning level signals through intelligent algorithms. These early warning level signals cover key elements such as the intensity of the earthquake, the location of the epicenter, the expected impact range, or the geological disaster meteorological early warning level, or the flood early warning level. The National Earthquake Monitoring Network, the geological disaster meteorological early warning platform, the flood early warning platform intelligent video analysis system, or the sensor simulation signal acquisition system sends these early warning level signals to the IoT platform server accurately and timely through a variety of communication methods, including API (application programming interface), ICP (network content provider), 5G network and MQTT (message queue telemetry transmission). The IoT platform server will preset the seismic fortification intensity, geological disaster meteorological response risk level and flood response risk level based on the danger, disaster susceptibility and vulnerability of the target area. After receiving these signals, they will be compared with the preset response risk level. If they are greater than or equal to the preset value, a multi-hazard response signal will be issued. These directives are intended to provide clear guidance and direction for subsequent emergency response, improve the accuracy and reliability of early warnings, minimize the potential damage caused by earthquakes, geological disasters, meteorology and floods, and reduce the probability and severity of secondary disasters of multiple types.

[0019] Step S200: The Internet of Things platform server sends the emergency response instruction to the edge computing gateway;

[0020] Specifically, after the IoT platform server completes the generation of emergency response instructions, it immediately transmits these critical instructions to the multi-hazard edge computing gateway through the efficient 4G / 5G signal network. With the characteristics of high speed, low latency and stable connection of 4G / 5G signals, it ensures that the instructions can be delivered at a very fast speed and with high accuracy. This not only effectively reduces the time loss during the transmission of instructions, but also minimizes the possibility of data loss or errors. In this way, it provides a strong guarantee for the subsequent multi-hazard edge computing gateway to quickly and accurately perform corresponding operations, so that the entire earthquake, geological disaster meteorology and flood emergency response process can be more smooth and efficient, and the accuracy and reliability of early warning and response are improved.

[0021] Step S300: The multi-hazard edge computing gateway generates a transmission line gate closing instruction, a railway and highway gate closing instruction, and an audible and visual alarm instruction based on the multi-hazard response signal;

[0022] Specifically, the multi-hazard edge computing gateway receives the multi-hazard emergency response signal from the IoT platform server and generates transmission line gate closure instructions, railway and highway gate closure instructions, and sound and light alarm instructions. The instruction accurately specifies the target transmission line gate closure and road gate closure that need to be closed to prevent further electric shock and traffic accidents in the event of earthquakes, geological disasters, meteorological conditions, and floods. At the same time, the gateway also generates sound and light alarm instructions. The instruction contains detailed parameters such as the alarm mode, intensity, and duration, and is intended to send a striking sound and light alarm to the surrounding environment in the most effective way to remind people to pay attention to earthquakes, geological disasters, meteorological conditions, and floods.

[0023] Step S400: If the edge computing gateway cannot receive 4G and 5G signals, the edge computing gateway lowers the preset value of the intelligent video digital signal response level and the sensor analog signal response threshold of the target area;

[0024] When earthquakes, geological disasters, meteorological events, and floods occur, the surrounding 4G / 5G communication base stations will be damaged, and the communication between the IoT platform server and the edge computing gateway will be cut off. The edge computing gateway will lower the preset value of the intelligent video digital signal response level and the sensor analog signal response threshold of the target area according to the presence or absence of the 4G / 5G signal of the networking platform, as well as the pre-set rules and strategies, to achieve early emergency response under special circumstances. Specifically, the multi-hazard edge computing gateway receives intelligent video digital signals and sensor analog signals through its equipped I / O (input / output) or AO (analog output) interface. When the video digital signal received by the multi-hazard edge computing gateway is greater than or equal to the preset value of the response level, or the sensor analog signal is greater than or equal to the response threshold, it will issue a power transmission line shutdown or road closure command and an audible and visual alarm command. The relevant modules in the multi-hazard edge computing gateway will output the command signal indicating the gate closure in the form of a digital signal through the I / O interface according to the established protocol and format, or transmit it in the form of an analog quantity through the AO interface. For the I / O interface, it involves the circuit system inside the gateway. When an instruction needs to be sent, the relevant circuit will switch the state and output a specific high and low level combination or digital code. These digital signals directly correspond to the operation instructions for closing the gate. The AO interface converts the digital instructions into continuously changing analog signals, such as voltage or current signals within a certain range, through the digital-to-analog conversion circuit. This analog signal can more accurately control some situations that require fine gate action. When the transmission line shut-off gate and the road closing gate receive digital signals from the I / O interface or analog signals from the AO interface, the control circuit or actuator inside the gate will interpret and process these signals. If it is an electric gate, the closing action of the gate will be controlled by motor drive, electromagnetic coil, etc. For example, when a high-level signal or a current / voltage of a certain size is received, the electric actuator will start, drive the gate's closing mechanism, and quickly close the gate to cut off the transmission line or railway highway. In addition, in order to ensure the reliability and accuracy of command transmission, the connection between the multi-hazard edge computing gateway and the gate adopts shielded cables, anti-interference circuits and other measures to reduce the impact of external interference on the signal. At the same time, real-time monitoring and verification will be carried out. Once the command transmission is abnormal or the gate status feedback does not meet expectations, an alarm will be issued in time or corresponding error correction measures will be taken to ensure the safety and reliability of the entire shutdown operation. It helps to quickly shut down the transmission line or railway highway at the critical moment of the disaster, reducing the probability of secondary disasters such as electric shock and traffic accidents.

[0025] Embodiment 2

[0026] Based on the same inventive concept as the earthquake, geological disaster, meteorological and flood IoT intelligent early warning and response method in the aforementioned embodiment, Figure 2As shown, the present application provides an IoT intelligent early warning and response platform for earthquakes, geological disasters, meteorology and floods. The platform and method embodiments in the present application are based on the same inventive concept. The platform includes:

[0027] The multi-hazard intelligent early warning and response platform includes the national earthquake monitoring network, the geological disaster meteorological early warning platform, the hydrological agency early warning platform, the Internet of Things platform server, the multi-hazard edge computing gateway, the intelligent video analysis system, the sensor analog signal acquisition system, the transmission line shut-off gates, the road closure gates and the sound and light alarm controller.

[0028] The input end of the Internet of Things platform server is connected to the national earthquake monitoring network, the geological disaster meteorological early warning platform, and the hydrological agency early warning platform, and the output end of the Internet of Things platform server is connected to the multi-hazard edge computing gateway.

[0029] The multi-hazard edge computing gateway uses a parallel communication architecture to connect the intelligent video analysis system, sensor analog signal acquisition system, transmission line shut-off gate, road closure gate and sound and light alarm controller for independent data exchange.

[0030] The Internet of Things platform server is pre-deployed in the cloud.

[0031] Specifically, the National Earthquake Monitoring Network, the Geological Disaster Meteorological Warning Platform, and the Hydrological Institution Warning Platform are the sources for the entire warning platform to obtain information related to earthquake levels, geological disaster meteorological warning levels, and flood warning levels, and are responsible for real-time monitoring and collection of earthquake activities, geological disaster meteorological, and flood data. The IoT platform server plays a core role in data processing and decision-making, analyzing and judging data from the National Earthquake Monitoring Network. The emergency edge computing gateway plays an auxiliary role in data processing and decision-making, analyzing and judging data from the intelligent video analysis system and sensor analog signals. The multi-hazard edge computing gateway serves as a bridge connecting different devices and systems to achieve efficient data transmission and conversion. The intelligent video analysis system and sensor acquisition system at the disaster site are used to promptly detect the disaster situation at the disaster site and provide trigger conditions for subsequent response measures. The power transmission line shut-off gate and road closure gate are specific execution components. After receiving relevant instructions, they take closing actions to prevent the occurrence of secondary disasters. The sound and light alarm controller is responsible for issuing warnings to the surrounding area through sound and light when a disaster occurs, reminding personnel to take corresponding safety measures. In general, this earthquake early warning response platform integrates a variety of equipment and systems to form a comprehensive, timely and effective system for responding to earthquakes and related secondary disasters.

[0032] The input end of the IoT platform server is connected to the National Earthquake Monitoring Network (through API, ICP and MQTT), which means that the earthquake-related data monitored by the National Earthquake Monitoring Network can be directly transmitted to the IoT platform server. The output end of the IoT platform server is connected to the multi-hazard edge computing gateway. After the server processes and analyzes the received earthquake, geological disaster meteorological and flood warning data, it will pass the corresponding instructions, information, etc. to the multi-hazard edge computing gateway through the output end (through 4G / 5G signals). This connection method builds a data flow link, so that the original data obtained from the National Earthquake Monitoring Network can be processed and converted, and finally accurately conveyed to the multi-hazard edge computing gateway, providing a basis for a series of subsequent control and response actions.

[0033] The multi-hazard edge computing gateway adopts a parallel communication architecture in the communication mode with the intelligent video analysis system, sensors, power line shut-off gates, road closure gates and sound and light alarm controllers at the disaster site. Parallel communication means that the multi-hazard edge computing gateway can exchange data with these devices at the same time, rather than one by one. This can greatly improve the efficiency and speed of data transmission, allowing each device to exchange information with the edge computing gateway in a timely and independent manner, achieving efficient collaborative work. Among them, the multi-hazard edge computing gateway is connected to the video analysis system and sensors through RS232, RS485 or AI interfaces, and is connected to the power line shut-off gates, road closure gates and sound and light alarm controllers through I / O or AO interfaces.

[0034] The IoT platform server is pre-configured and installed in the cloud environment. Pre-deploying the server in the cloud has many advantages. For example, the cloud can provide powerful computing and storage resources, which can be flexibly expanded according to actual needs to meet the needs of processing large amounts of data and high concurrent requests. At the same time, the high availability and fault tolerance of the cloud can ensure the stable operation of the server and reduce service interruptions caused by hardware failures and other problems. In addition, cloud deployment also facilitates remote management and maintenance, reducing operation and maintenance costs and complexity.
