DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] To make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below in conjunction with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a 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 those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0016] The following will describe in detail the technical solutions provided by each embodiment of the present application in conjunction with the drawings.

[0017] As Figure 1 shown, to solve the above problems, a data transmission method for water conservancy informatization provided by an embodiment of the present application is applied in a data transmission system for water conservancy informatization. The system includes a cloud data center, a controller, edge devices, and water conservancy monitoring terminal devices. The method includes: S101. The edge device includes a cloud edge device and a terminal edge device. The terminal edge device receives data from the water conservancy monitoring terminal device and transmits the data to the controller, and the cloud edge device receives data from the controller.

[0018] The system architecture is optimized based on the traditional water conservancy informatization system, and an SD-WAN control system is added. This system includes an SD-WAN controller and SD-WAN edge devices. The optimized system composition includes a cloud data center, an SD-WAN controller, a wide area network, SD-WAN edge devices, and water conservancy monitoring terminal devices. The DetNet and TSN protocols are deeply integrated into the SD-WAN control system to jointly build a flattened large-scale water conservancy information system architecture. This architecture has high flexibility and can selectively add sub-centers according to actual needs. The overall system design aims to improve the efficiency and reliability of data transmission and provide strong technical support for water conservancy informatization.

[0019] The cloud data center accesses the SD-WAN control system by using SD-WAN edge devices, which specifically include SD-WAN routers or CPEs, that is, customer premise equipment. Considering the high requirements of the cloud data center for network performance, high-performance SD-WAN edge devices are usually used to meet its network needs.

[0020] For the access of water conservancy monitoring terminal devices, SD-WAN edge devices are also used, including SD-WAN routers or CPEs. These devices need to be selected according to the on-site transmission distance and network requirements, and support multiple access methods such as 4G, 5G, Wi-Fi, LoRa, RS-232, RS-485, etc., to ensure flexibility and adaptability. There are various types of water conservancy monitoring terminal devices, including but not limited to water level sensors, water quality monitoring devices, rain gauges, flow monitoring devices, deformation monitoring devices, and video monitoring devices, etc., comprehensively covering the monitoring needs of water conservancy informatization.

[0021] S102. The controller receives data from the terminal edge device, analyzes and processes the data, and sends the processed data to the cloud edge device.

[0022] S103. The cloud data center deploys the edge devices and communicates with the controller through the cloud edge device.

[0023] Deploy the control plane of SD-WAN in the cloud, enabling the end devices of SD-WAN to directly connect to the SD-WAN controller in the cloud, thus simplifying network deployment and centralizing management. Based on the time-sensitive communication protocol of DetNet, the system can provide strict latency and jitter control to ensure that critical data such as flood warning information in the water conservancy system can be accurately transmitted to the target node within the specified time. At the same time, combined with the dynamic routing selection mechanism of SD-WAN, the system can intelligently select the path that meets the deterministic transmission requirements among multiple links, effectively avoiding delays and packet losses caused by link fluctuations.

[0024] Through the traffic classification and scheduling mechanism of the deterministic network, the system can classify different types of data streams, including water level monitoring, video surveillance, warning signals, etc. and reasonably allocate different transmission priorities. This mechanism guarantees the bandwidth requirements of high-priority services such as flood warnings, effectively reducing latency, while shaping the traffic of low-priority services to avoid resource competition. In addition, by using the traffic redundancy transmission mechanism of DetNet and sending critical data through multi-link redundancy technology, it ensures that even if a link fails, the data can still reach the target node in real time and reliably through the backup link.

[0025] The link aggregation and load balancing functions of SD-WAN further improve the utilization rate of link resources and effectively reduce the probability of network congestion. The global network status awareness ability of the SD-WAN controller enables the system to monitor and schedule network links in real time and dynamically select the best transmission path that meets the deterministic requirements. Especially when the water conservancy business demand is urgent, the deterministic scheduling algorithm can give priority to ensuring the transmission of critical data streams, ensuring the overall performance and reliability of the system.

[0026] The implementation of the deterministic network relies on the wide area network foundation provided by the SD-WAN control system, which itself is secure, stable and efficient. On this basis, by embedding DetNet and TSN technologies, the jitter and latency in network transmission are further reduced, thus realizing the functions of the deterministic network. This design ensures high determinacy and high reliability of network transmission, meeting the strict requirements of the water conservancy informatization system for critical data transmission.

[0027] In one embodiment, in a deterministic network, the transmission priority of data streams is strictly followed to ensure the priority transmission of critical data. Specifically, the system performs corresponding rate control on the received data according to the pre-set transmission priority rules. For high-priority data, such as flood warning information, the system assigns it a higher transmission rate to ensure that it is processed and transmitted within the shortest time to meet the real-time requirements. For low-priority data, such as daily monitoring data, the system will impose appropriate rate limits to avoid occupying too much network resources and affecting the transmission of high-priority data.

[0028] At the same time, to ensure the reliability and redundancy of data transmission, the system pre-sets multiple transmission paths. When data needs to be transmitted, the system simultaneously uses these transmission paths to send the data. This multi-path transmission strategy effectively reduces the risk of data loss caused by a single-path failure. Even if a certain path has problems, other paths can still ensure the complete transmission of data. In this way, while ensuring the data transmission efficiency, the system also greatly improves the reliability and stability of the network.

[0029] In one embodiment, during the data transmission process, the system first accurately determines the data stream type and classifies and allocates the data according to predefined rules, so as to clarify the transmission priority corresponding to each type of data. Subsequently, the data is sorted for orderly transmission according to these priorities to ensure that high-priority data such as flood warnings can be transmitted first.

[0030] The controller, as the core of the system, is responsible for comprehensively monitoring and intelligently scheduling the network link in real time. By deeply analyzing the network status, the controller can quickly determine the best transmission path and closely combine it with the actual needs of the water conservancy business, especially for the urgent transmission needs of critical data such as flood warning information, and preferentially arrange it to be efficiently transmitted through the best path.

[0031] In addition, the controller also dynamically adjusts and optimizes the network link according to the pre-set routing strategy to ensure that the best transmission path can be quickly locked in any network condition. At the same time, the system supports multi-link aggregation technology, which integrates multiple physical network links into one logical link to achieve effective superposition of broadband resources, further improving the network transmission capacity and the overall performance of the system, and ensuring the efficiency and stability of data transmission.

[0032] In one embodiment, when optimizing the transmission performance of the water conservancy informatization system, key performance indicators are first defined and set. These indicators cover core elements such as latency, jitter, packet loss rate, and bandwidth utilization, aiming to comprehensively evaluate the quality and efficiency of network transmission. The system continuously monitors these performance indicators in real time, and through advanced data acquisition and analysis technologies, quickly obtains accurate monitoring results. Based on these monitoring results, the system can intelligently identify bottlenecks and potential problems in network transmission and make fine-tuning of link configurations accordingly. For example, when it is detected that the latency or jitter exceeds the preset threshold, the system will automatically trigger an adjustment mechanism to optimize the routing selection or increase the link bandwidth to quickly reduce latency and jitter and ensure the real-time and stability of data transmission. At the same time, in response to a high packet loss rate, the system will adjust the transmission strategy or enhance the error correction ability to ensure the integrity and reliability of data. In addition, the system will dynamically adjust resource allocation according to the monitoring results of bandwidth utilization to maximize the utilization of network resources and improve the overall transmission efficiency.

[0033] In one embodiment, to ensure the security and reliability of data transmission, the business types of data are first clarified. For different types of business data, the system implements strict logical isolation measures. This logical isolation can not only effectively prevent interference between different business data, but also improve the overall security and stability of the system. Specifically, according to the business attributes of the data, the system assigns it to the corresponding logical isolation area. Subsequently, the logically isolated data is encrypted, and advanced encryption algorithms are used to ensure the confidentiality and integrity of the data during transmission. Encrypted transmission can not only effectively resist external network attacks and data theft risks, but also ensure the compliance of data transmission and meet relevant requirements. Through this series of security measures, the water conservancy informatization system can ensure the security and privacy of various business data during transmission, providing a solid technical guarantee for key links such as water conservancy monitoring, early warning, and decision-making support. At the same time, this also lays a solid foundation for the long-term stable operation and sustainable development of the water conservancy informatization system.

[0034] In one embodiment, in order to ensure data security and timeliness, the large-scale water conservancy informatization system of the present application mostly uses MPLS dedicated lines, and the construction and operation and maintenance costs are relatively high. By adopting SD-WAN technology, on the premise of ensuring data security, the dependence on dedicated lines is reduced. By supporting low-cost links such as broadband Internet, 4G / 5G, and combined with MPLS dedicated lines, the construction and operation and maintenance costs of the overall link are reduced. At the same time, the bandwidth expansion cost is also greatly reduced, and the construction and operation and maintenance costs of the transmission network are reduced by more than 50%.

[0035] With the help of deterministic network technology and dynamic routing optimization strategies, the system can accurately control the end-to-end delay of data transmission at the millisecond level while reducing the jitter amplitude to a negligible level. This feature is particularly applicable to application scenarios with extremely high real-time requirements such as flood warnings. In a traditional network environment, the data transmission delay highly depends on the link quality, generally ranging from 50 to 200 milliseconds, and the fluctuations are significant, making it difficult to meet the high real-time requirements. After introducing the SD-WAN dynamic routing selection mechanism and the time-sensitive communication protocol of the deterministic network, the delay is significantly reduced to 10 to 50 milliseconds, and the transmission stability is significantly improved. In addition, the jitter range of the traditional network fluctuates between 20 and 100 milliseconds, which cannot effectively guarantee the quality of real-time data transmission. Through the intelligent traffic scheduling function of the deterministic network, the jitter is strictly controlled within 1 to 5 milliseconds, fully meeting the stringent requirements of real-time data transmission for low delay and low jitter.

[0036] Through traffic redundancy and dynamic link switching, the data packet loss rate is significantly reduced, ensuring the reliable transmission of critical data. Through the traffic scheduling function of the deterministic network, the jitter is controlled within the range of "1 - 5 ms", meeting the real-time data transmission requirements. Combining with the redundant transmission function of the deterministic network, the packet loss rate can be reduced to "0.01% - 0.1%".

[0037] Through the link aggregation and load balancing technology of SD-WAN, combined with the traffic scheduling mechanism of DetNet, the optimal utilization of link resources is achieved, improving the overall network bandwidth utilization rate. The link utilization rate of the traditional network is generally 30% - 50%. After integrating SD-WAN and the deterministic network, the link utilization rate can be increased to 75% - 90%.

[0038] Combining the end-to-end encryption technology of SD-WAN and the traffic isolation mechanism of DetNet significantly improves the data security and network reliability of the water conservancy informatization system. This application supports centralized management and intelligent operation and maintenance. Combining with the traffic engineering function of the deterministic network, manual intervention is greatly reduced, the fault recovery time is significantly shortened, and the network maintenance cost is reduced.

[0039] As Figure 2 shown, the embodiment of this application also provides a data transmission device for water conservancy informatization, including: At least one processor; and, A memory communicatively connected to at least one processor; wherein, The memory stores instructions executable by at least one processor. The instructions are executed by at least one processor so that a data transmission device for water conservancy informatization can execute: the method described in any one of the above embodiments.

[0040] The embodiment of the present application further provides a non-volatile computer storage medium storing computer-executable instructions, and the computer-executable instructions are configured to be the method described in any one of the above embodiments.

[0041] In the 1990s, it was quite obvious to distinguish whether an improvement in a technology was an improvement in hardware (e.g., improvement in circuit structures such as diodes, transistors, switches, etc.) or an improvement in software (improvement in method flows). However, with the development of technology, many improvements in method flows today can be regarded as direct improvements in hardware circuit structures. Almost all designers obtain the corresponding hardware circuit structures by programming the improved method flows into the hardware circuits. Therefore, it cannot be said that an improvement in a method flow cannot be implemented with a hardware entity module. For example, a Programmable Logic Device (PLD) (such as a Field Programmable Gate Array (FPGA)) is such an integrated circuit whose logical function is determined by the user's programming of the device. The designer can program by himself to "integrate" a digital system on a piece of PLD, without having to ask a chip manufacturer to design and fabricate a dedicated integrated circuit chip. Moreover, nowadays, instead of manually fabricating integrated circuit chips, this programming is mostly implemented using "logic compiler" software, which is similar to the software compiler used in program development and writing. The original code before compilation also has to be written in a specific programming language, which is called a Hardware Description Language (HDL). And there is not only one kind of HDL, but many kinds, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc. The most commonly used ones currently are VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog. Those skilled in the art should also be aware that by simply making a little logical programming of the method flow with the above-mentioned several hardware description languages and programming it into the integrated circuit, it is easy to obtain the hardware circuit that implements the logical method flow.

[0042] The controller can be implemented in any suitable manner. For example, the controller can take the form of, for example, a microprocessor or a processor and a computer-readable medium storing computer-readable program code (such as software or firmware) executable by the (micro)processor, logic gates, switches, an application specific integrated circuit (ASIC), a programmable logic controller, and an embedded microcontroller. Examples of the controller include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320. The memory controller can also be implemented as part of the control logic of the memory. Those skilled in the art also know that, in addition to implementing the controller in the form of pure computer-readable program code, it is entirely possible to logically program the method steps to enable the controller to be implemented in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers, etc. to achieve the same functions. Therefore, such a controller can be considered a hardware component, and the devices included therein for implementing various functions can also be regarded as the structures within the hardware component. Or even, the devices for implementing various functions can be regarded as either software modules for implementing the method or the structures within the hardware component.
