Description

Technical Field

[0001] This invention relates to the field of intelligent Internet of Things (IoT) communication technology, and specifically to a method for automatic switching and resource coordination of systems in everyday and extreme scenarios. Background Technology

[0002] In recent years, with the rapid development of science and technology, smart Internet of Things (IoT) technology has gradually matured and improved. Edge computing devices have been deployed on various public facilities to monitor equipment status and collect public data. However, a large number of edge computing devices generate a large amount of data, and ordinary IoT networks are insufficient to support the massive instantaneous data volume. In the event of an emergency, communication links are prone to congestion, leading to data loss, which is not conducive to the timely collection of critical data, decision-making, and issuing instructions. Summary of the Invention

[0003] The purpose of this invention is to propose a method for automatic switching and resource coordination of systems in daily and extreme scenarios, so as to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] To achieve the above technical objectives, the technical solution of the present invention is as follows:

[0005] In a first aspect, the present invention provides a method for automatic switching and resource coordination of a system under normal and extreme scenarios, the method comprising the following steps:

[0006] Step 1: Deploy probe programs on all edge nodes and initialize the first state of all edge nodes to "off". Set the center node and initialize the first state of the center node to "off".

[0007] Step 2: Use the probe program to collect data, load preset rules to process the collected data, generate first data, and transmit the first data to the central node;

[0008] Step 3: After the central node obtains the first data of all edge nodes, it makes a judgment. If the judgment result meets the preset conditions, it sends a state switching instruction to each edge node and switches the first state of the central node to "on".

[0009] Step 4: After receiving the state switching instruction, the edge node switches its first state to "on", loads new preset rules, processes the data, generates second data, and transmits the second data to the central node.

[0010] Step 5: After obtaining the first and second data of all edge nodes, the central node makes a judgment. If the judgment result meets the preset conditions, the central node sends a device operation command to the edge node.

[0011] Furthermore, in step 1, the edge node is an Internet of Things (IoT) device deployed in urban power equipment, 4G / 5G communication equipment, gas facilities, residential water infrastructure, and key infrastructure such as highways, bridges, and dams, used to collect physical data and / or image data of urban infrastructure or natural environment.

[0012] Furthermore, the probe program is used to process the collected physical data and image data and transmit them to the central node; the central node is a server with data processing and decision-making capabilities, and the edge nodes are connected to the central node via the TLS protocol.

[0013] Preferably, the first state is used to mark the working state of the edge node and the center node. When the first state of the center node and the edge node is off, the center node and any edge node are configured not to transmit or receive any second data.

[0014] Further, in step 2, the sub-steps of using the probe program to collect data, loading preset rules to process the collected data, generating first data, and transmitting the first data to the central node are as follows:

[0015] Step 2.1: The probe program collects data and loads preset rules to process the collected data;

[0016] Step 2.2: The probe program processes the data and filters out outliers, and the outliers constitute the first data.

[0017] Step 2.3: The probe program transmits the first data to the central node.

[0018] Preferably, the abnormal data refers to the value of the collected data exceeding a set threshold, or the image data showing abnormalities such as the camera's field of view being obstructed, the protected area sending out dangerous information such as fire or flood, or abnormal information from edge devices.

[0019] Further, in step 3, after the central node obtains the first data of all edge nodes, it makes a judgment. If the judgment result meets the preset conditions, it issues a state switching instruction to each edge node and switches the first state of the central node to "on". The sub-step is as follows:

[0020] Step 3.1: Obtain the first state of the current central node. If the first state of the central node is closed, discard all second data.

[0021] Step 3.2: The central node processes the first data. If the judgment result meets the preset conditions, it sends a state switching instruction to each edge node. The central node sets the value of the first state to "on" and is configured to prioritize processing the second data.

[0022] Further, in step 4, the sub-steps of the edge node switching its first state to "on" after receiving the state switching instruction, loading new preset rules, processing the data, generating second data, and transmitting the second data to the central node are as follows:

[0023] Step 4.1: After the edge node obtains the state switching instruction, it sets the value of the first state to "on". The probe program of the edge node processes the collected data, loads new rules, and filters out outliers. The outliers constitute the second data.

[0024] Step 4.2: The probe program transmits the second data to the central node.

[0025] Preferably, after the state switching instruction is broadcast or transmitted, the first state value of the edge node is set to "on," the original processing rules remain in effect, and the original processing rules continue to generate the first data, which is then transmitted to the intermediate node. After loading the new rules, outliers are filtered out, and these outliers constitute the second data. At this point, the edge node and the central node prioritize processing the second data. This design helps to prioritize processing data in emergency situations, i.e., data generated by loading the new rules, and then process or discard the first data when the edge node and the central node have spare resources.

[0026] Preferably, after the first state of the edge node is set to "on", the probe program also changes the data acquisition method and frequency.

[0027] Preferably, after the first state of the edge node is set to enabled, the transmission method of the first and second data will also be changed, using different links for transmission and reception.

[0028] Further, in step 5, the sub-step where the central node obtains the first and second data of all edge nodes and makes a judgment, and if the judgment result meets the preset conditions, then sends a device operation command to the edge nodes, is as follows:

[0029] After the central node obtains the first data and the second data from all edge nodes, it processes the first data and the second data. If the judgment result meets the preset conditions, it sends a device operation command to the edge node. The data processing priority of the second data is higher than that of the first data.

[0030] Preferably, the device operation commands include operations such as forced shutdown, restart, self-destruct, and activating backup equipment.

[0031] Preferably, the device operation commands are transmitted using the same or different links.

[0032] Preferably, the device operation commands are transmitted simultaneously across different links.

[0033] Preferably, the priority of sending and receiving the device operation command is different before and after the value of the first state changes.

[0034] Preferably, after the first state is activated, the device operation command has a second priority, which takes precedence over the original downlink data command transmission.

[0035] Preferably, all undefined variables in this invention, if not explicitly defined, can be manually set thresholds.

[0036] Secondly, the present invention provides an automatic switching and resource coordination system for systems in daily and extreme scenarios, the system comprising:

[0037] Edge Node: The edge node runs a probe program. The edge node is an Internet of Things (IoT) device deployed in key infrastructure such as power equipment, 4G / 5G communication equipment, gas facilities, residential water infrastructure, highways, bridges, and dams in the city. It is used to collect physical data and / or image data of the infrastructure or natural environment in the city. The probe program is used to process the collected physical data and image data, generate first data and second data, and transmit them to the central node.

[0038] Central Node: The central node is a server with data processing and decision-making capabilities. The edge nodes are connected to the central node via the TLS protocol. The central node processes the first and second data from the edge nodes, sends device operation instructions and state switching instructions, and loads different processing rules and priorities on the first and second data according to the first state to generate device operation instructions and state switching instructions.

[0039] Preferably, the edge nodes and the central node have communication capabilities, and data transmission between the edge nodes and the central node is carried out using data links. The data links include Ethernet, power line carrier, optical fiber, 433MHz, infrared, Bluetooth LE, Wi-Fi, ZigBee, SigFox, 2.4G, GSM cellular network, 4G LTE Cat.1 network, NB-IoT, LoRa, 5G-R railway dedicated communication network, microwave communication link, Beidou satellite communication link, Iridium satellite communication link, and maritime satellite link.

[0040] Preferably, the edge node and the central node can communicate through two or more data link types, and use different data links to transmit the first data and the second data, as well as the device operation instructions and the state switching instructions.

[0041] Preferably, the data link further includes RS485, RS232, FM radio, and AM radio.

[0047] Figure 2 This is a schematic block diagram of an automatic switching and resource coordination system structure for everyday and extreme scenarios, according to an embodiment of the present invention. Detailed Implementation

[0048] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. The specific embodiments described herein are only for explaining the invention and are not intended to limit the invention.

[0049] It should also be understood that the following embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-essential improvements and adjustments made by those skilled in the art based on the above description of the present invention are within the scope of protection of the present invention. The specific process parameters, etc., in the following examples are merely examples within a suitable range; that is, those skilled in the art can make appropriate selections within the appropriate range based on the description herein, and are not intended to be limited to the specific values ​​in the examples below.

[0050] The following exemplifies an automatic switching and resource coordination method for a system in everyday and extreme scenarios provided by the present invention.

[0051] like Figure 1 The diagram shows a flowchart of a method for automatic switching and resource coordination in daily and extreme scenarios. The following section will combine... Figure 1 This invention describes an automatic switching and resource coordination method for a system under normal and extreme scenarios according to an embodiment of the present invention. The method includes the following steps:

[0052] Step 1: Deploy probe programs on all edge nodes and initialize the first state of all edge nodes to "off". Set the center node and initialize the first state of the center node to "off".

[0053] Step 2: Use the probe program to collect data, load preset rules to process the collected data, generate first data, and transmit the first data to the central node;

[0054] Step 3: After the central node obtains the first data of all edge nodes, it makes a judgment. If the judgment result meets the preset conditions, it sends a state switching instruction to each edge node and switches the first state of the central node to "on".

[0055] Step 4: After receiving the state switching instruction, the edge node switches its first state to "on", loads new preset rules, processes the data, generates second data, and transmits the second data to the central node.

[0056] Step 5: After obtaining the first and second data of all edge nodes, the central node makes a judgment. If the judgment result meets the preset conditions, the central node sends a device operation command to the edge node.

[0057] In one embodiment, edge nodes are deployed in urban infrastructure such as power equipment, 4G / 5G communication base stations, gas facilities, and residential water supply.

[0058] After collecting infrastructure data, edge nodes process the data. If any data anomalies are detected, the data is sent to the central node. The central node can combine data from multiple edge nodes, giving it greater processing power. Based on configured alarm parameter thresholds or AI inference, it can determine whether an emergency has occurred, such as an earthquake or strong winds causing widespread infrastructure damage, and then decide on the next course of action.

[0059] The edge nodes of the power equipment use power line carrier to transmit the first data, while also having 4G IoT communication capability as a backup.

[0060] If the central node determines that a large-scale disaster has occurred and an emergency state needs to be entered, it sends a state switching command, and the entire system enters an emergency state. After the state switching between the edge nodes and the central node is completed, both the edge nodes and the central node load another set of data processing and decision-making rules, such as different data transmission methods, data collection frequencies, and processing methods for the edge nodes. At certain critical facilities, certain data is collected more intensively, or the collection frequency of certain data types is reduced, and the reporting frequency is adjusted to reduce the load on communication links, dynamically adjusting the frequency of critical data collection. For example, the reporting frequency of water supply facilities is reduced to free up communication resources and save the processing load on the central node, while maintaining its own data processing capabilities and only reporting critical data.

[0061] For example, bridge detection data is obtained through displacement sensors, vibration sensors, etc., deployed on the bridge. If the sensor data is abnormal after an earthquake, the safety of the bridge can be further determined based on the images from the camera. After the central node judges the data, it needs to issue equipment operation instructions, such as controlling traffic signals and issuing other alarms.

[0062] After judging the data, the central node can also filter out other edge nodes that need to issue equipment operation commands and execute the action of closing the gas valve.

[0063] Both edge and central nodes are configured with multiple data transmission methods. Normally, they use existing low-cost links such as LTE Cat.1 or wired links. For high-volume data transmission, such as camera images, 4G / 5G links or wired Ethernet are used to ensure availability, transmitting camera footage in real-time. The powerful computing and storage capabilities of the central node are utilized, eliminating the limitations imposed by the lower performance of edge nodes. However, during large-scale disasters, some links may be damaged, public lines may be congested, and some central nodes may go offline. In such cases, a switch to lower-speed, more expensive but more reliable communication methods, such as ad hoc networks or satellite transmission, is necessary. This requires reducing data transmission volume. Edge nodes load different data processing methods and reporting frequencies. For example, edge nodes process image data, filter feature points, and make judgments, reporting only the results to save communication bandwidth and central node computing power. Since some edge nodes require more frequent and detailed data reporting, such as road and bridge infrastructure reports, the central node also loads different rules to process data and make decisions.

[0064] Through a distributed, monitorable, and controllable intelligent probe system, and a hierarchical system design for global status and data commands, the system fully realizes the rapid switching logic and resource scheduling coordination in both daily refined management of the city and extreme scenarios.

[0065] Preferably, all undefined variables in this invention, if not explicitly defined, can be manually set thresholds.
