Description

Technical Field

[0001] This application relates to the field of water conservancy information transmission technology, specifically to a multi-channel water conservancy information communication terminal. Background Technology

[0002] With the rapid development of new-generation information technologies such as mobile communication and BeiDou short message communication, as well as the integrated development and mature application of water conservancy technologies, and based on the overall requirement of the Ministry of Water Resources to drive water conservancy modernization through informatization, my country's water conservancy has now completed the transition from the automation stage to the informatization stage and is gradually moving towards the intelligent stage. Intelligent water conservancy permeates systems such as flood control, drought relief, disaster reduction, rational allocation and efficient utilization of water resources, and the protection of water resources and river and lake health, and the requirements for the real-time performance and reliability of hydrological and hydrological information transmission are becoming increasingly stringent.

[0003] Due to the complex watershed environments and vast geographical spans where water conservancy projects are located, terrestrial communication networks often cannot achieve full coverage of remote or complex terrain. Even in areas with terrestrial network coverage, extreme rainfall and floods can destroy power facilities and damage communication base stations, resulting in power outages and network disruptions. Furthermore, heavy rain can cause rainfall attenuation, leading to communication interruptions and affecting data stability and quality. Therefore, when monitoring information cannot be transmitted or early warning information cannot be issued, issues related to data stability and quality arise.

[0004] To address data stability and quality issues, the current water conservancy communication terminal employs a dual-channel communication mode using terrestrial mobile networks and BeiDou short message service. It primarily uses 2G / 3G / 4G terrestrial mobile networks as the primary channel, while BeiDou satellite serves as a backup channel. Normally, the device will prioritize communication via the terrestrial mobile network; however, when the terrestrial mobile network signal quality is poor, it will automatically switch to BeiDou satellite communication to ensure communication continuity and stability.

[0005] Although terrestrial mobile networks offer high coverage and low costs in densely populated areas, making them a primary means of water resources information collection, 67% of the country's land area still lacks terrestrial network signal coverage. Furthermore, natural disasters such as earthquakes, tsunamis, and forest fires can destroy communication infrastructure and completely damage backhaul networks. The establishment of the BeiDou satellite short message communication system is of extraordinary significance for economic development and national defense modernization, effectively solving emergency communication problems in many areas with no terrestrial network coverage (such as uninhabited areas, deserts, oceans, and polar regions) or where communication base stations have been damaged (such as in earthquakes, floods, and typhoons).

[0006] However, in practical applications, BeiDou short message communication also has the following shortcomings: ① It is susceptible to environmental factors such as weather, resulting in a relatively high data transmission error rate; ② The length and frequency of short messages affect the flexibility of civilian use, making it difficult to achieve efficient transmission of high-definition images or videos; ③ BeiDou short message communication is inherently unreliable communication. Coupled with factors such as packet loss and data transmission errors, the sending end cannot definitively know whether the message has been successfully sent. According to statistics, the success rate of single data packet transmission in civilian BeiDou short message communication is 95.5%. In emergency situations, the reliability and success rate of water conservancy information transmission are crucial to strengthening my country's dynamic monitoring of water security and emergency response capabilities.

[0029] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] In the description of this application: unless otherwise stated, "a plurality of" means two or more. The terms "first," "second," "third," etc., in this application are intended to distinguish the objects referred to and do not have any special meaning in terms of technical connotation (e.g., they should not be construed as an emphasis on importance or order). Expressions such as "comprising," "including," and "having" also mean "not limited to" (certain units, components, materials, steps, etc.).

[0031] The terms used in this application, such as "upper," "lower," "left," "right," and "middle," are generally used to indicate the general relative positional relationship for the purpose of intuitive understanding by referring to the accompanying drawings, and are not absolute limitations on the positional relationship in the actual product.

[0032] In recent years, my country's satellite systems and networks have made significant progress, possessing more efficient, reliable, and high-speed data transmission capabilities, while also supporting new application scenarios. This application utilizes my country's existing Ku-band geostationary orbit satellite resources and the medium- and low-Earth orbit Ku-band satellite communication systems under construction. Relying on the two-way confirmation function of the Ku-band satellite communication transmission system, it can provide a reliable, network-coverage-free, multi-channel backup information transmission path to improve the applicability, reliability, and success rate of information transmission for water conservancy communication terminals, meeting the real-time and reliability requirements of key service areas and important data transmission.

[0033] Please see Figure 1 This application provides a multi-channel water conservancy information communication terminal (hereinafter referred to as the "terminal"), including a multi-channel data processing unit 1 and a multi-channel antenna unit 2. The multi-channel data processing unit 1 includes a main control module 101, a Ku-channel water conservancy information IoT dedicated baseband module 102, a mobile network module 103, and a Beidou transceiver module 104. The mobile network module can be a 5G single-mode module, a 4G single-mode module, a 3G single-mode module, or a multi-network standard multi-mode module compatible with 5G, 4G, and 3G, preferably a 5G module. The Beidou transceiver module 104 is preferably a Beidou transceiver module. The No. 3 transceiver module; the multi-channel antenna unit 2 includes a Ku-band radio frequency component 201, a Ku-band transceiver antenna 202, a mobile network antenna 203, a BeiDou receiving antenna 204, a BeiDou transmitting antenna 205, and a BeiDou / GPS positioning antenna 206. Among them, the mobile network antenna 203 can be a 5G single-mode antenna, a 4G single-mode antenna, a 3G single-mode antenna, or a broadband antenna compatible with 5G, 4G, and 3G, preferably a 5G antenna. The BeiDou receiving antenna 204 is preferably a BeiDou-3 receiving antenna, and the BeiDou transmitting antenna 205 is preferably a BeiDou-3 transmitting antenna.

[0034] Among them, the Ku-band satellite channel is composed of the Ku-band water conservancy information IoT dedicated baseband module 102, the Ku-band radio frequency component 201, and the Ku-band transceiver antenna 202; the mobile network channel is composed of the mobile network module 103 and the mobile network antenna 203; and the Beidou short message channel is composed of the Beidou transceiver module 104, the Beidou receiving antenna 204, the Beidou transmitting antenna 205, and the Beidou / GPS positioning antenna 206.

[0035] Specifically, the 5G antenna is used to receive and transmit 5G network signals; the BeiDou-3 receiving antenna is used to receive BeiDou-3 short message S-band signals; the BeiDou-3 transmitting antenna is used to transmit BeiDou-3 short message L-band signals; and the BeiDou / GPS positioning antenna 206 is used to receive BeiDou B1 band and GPS L1 band positioning signals.

[0036] The Ku-band radio frequency component 201 consists of RF circuits, local oscillator circuits, monitoring circuits, and DC / DC circuits. The receiving and transmitting channels are connected to the Ku-band transceiver antenna 202 via RF interfaces. Data to be transmitted by the terminal is modulated by the Ku-channel water conservancy information IoT dedicated baseband module 102, resulting in an intermediate frequency (IF) signal. This IF signal is then converted to the Ku-band frequency by a splitter and up-converter circuit, and then amplified by a power amplifier to generate transmit power, which is output to the Ku-band transceiver antenna 202. The received signal from the Ku-band transceiver antenna 202 is converted to an IF signal after passing through a transmit impedance filter, low-noise amplification, image frequency filtering, and mixing, and is then output to the Ku-channel water conservancy information IoT dedicated baseband module 102 for demodulation.

[0037] The Ku-band transceiver antenna 202 adopts a miniaturized and planar design. It can be used as a fixed-beam planar array antenna to transmit and receive communication signals with geostationary Ku-band satellites; or it can be used as a planar phased array antenna to transmit and receive communication signals with high, medium, and low orbit Ku-band satellites. Compared with existing parabolic or planar waveguide array antennas, the Ku-band transceiver antenna 202 in this application has significant advantages such as small size, light weight, low cost, and easy installation.

[0038] The Ku-channel water conservancy information IoT dedicated baseband module 102 serves as a backup data transmission channel. Its receiving and transmitting channels are connected to the Ku-band radio frequency component 201 via intermediate frequency interfaces. This module is used for data modulation, demodulation, and transmission / reception when 5G networks and BeiDou-3 short message functionality are unavailable, when BeiDou-3 short message transmission is not possible due to large data volumes, or when critical data transmission requires guaranteed transmission. For important data transmission, a receiver confirmation feedback function can be selected. After correctly receiving the data, the receiver will send a confirmation message of successful data reception to the terminal's main control module 101 via the Ku-channel. The main control module 101 only completes the data transmission process after receiving this confirmation feedback. If the confirmation message is not received within a specified time, the data will be retransmitted until a successful transmission confirmation is received.

[0039] The Ku-band water conservancy information IoT dedicated baseband module 102 supports existing Ku-band conventional satellites and high-throughput satellites, including geostationary orbit, medium orbit, and low orbit Ku-band communication satellites. It supports various networking methods such as star networking, mesh networking, and hybrid networking, supporting up to 100,000 terminal network applications. The Ku-band water conservancy information IoT dedicated baseband module 102 also supports multiple modulation methods such as BPSK, QPSK, 8PSK, 16APSK, and 32APSK, and is optimized for protocol transmission efficiency and channel latency based on the characteristics of satellite channel transmission, providing upload speeds from 1kbps to 1Mbps.

[0040] The 5G module serves as an alternative data transmission channel for transmitting and receiving water conservancy information. It is connected to the 5G antenna via an RF cable. The 5G module is compatible with all networks and supports 5G / 4G / 3G / 2G networks of the three major operators. It integrates RF, baseband, and SIM card to complete wireless reception, transmission, and baseband signal processing functions. It also optimizes the low-power mode for the transmission characteristics of water conservancy IoT.

[0041] The BeiDou-3 transceiver module serves as an alternative data transmission channel for transmitting and receiving short message information. The transmission and positioning channels are connected to the BeiDou-3 receiving antenna, BeiDou-3 transmitting antenna, and BeiDou / GPS receiving antenna via RF cables, respectively. It mainly includes a low-noise amplifier, power amplifier, channels, baseband processing, and BeiDou SIM card, and is compatible with the BeiDou user terminal general data interface 2.1 and 4.0 protocols. It integrates RNSS and RDSS and has all-weather positioning and navigation and two-way message communication functions.

[0042] The main control module 101, serving as the terminal's control center, integrates space-ground integrated water conservancy information processing software. It connects to the 5G module, the BeiDou-3 transceiver module, and the Ku-band water conservancy information IoT dedicated baseband module 102 via data interfaces. It performs communication protocol parsing and encapsulation, data transmission and control, and multi-channel communication link switching logic control. The main control module 101 also features a channel AI evaluation module, capable of establishing a database model encompassing multiple dimensions such as data type, data size, channel status, channel transmission time, channel transmission efficiency, channel transmission capacity, channel transmission success rate, and channel usage costs. This model comprehensively evaluates the application performance of the mobile network channel, the BeiDou short message channel, and the Ku-band satellite channel, and selects the optimal channel for data transmission when needed.

[0043] The water conservancy information preprocessing software can also classify and categorize data information according to its importance. For important data information exceeding a set level, the channel with the highest success rate is prioritized for transmission. To minimize terminal power consumption and meet the needs of field applications, the main control module 101 also has the following functions: ① On-demand power supply control for each channel: The mobile network channel, Beidou short message channel, and Ku-band satellite channel can all be set to work modes independently by the main control module 101, namely single-receive mode, single-transmit mode, sleep mode, and transmit / receive open mode. Entering sleep mode when not in use can effectively reduce terminal power consumption; ② Information preprocessing function: The main control module 101 can provide edge computing capabilities. Through the integrated built-in water conservancy information preprocessing software, it provides real-time data calculation and analysis for the comprehensive processing of massive water conservancy information, realizes accurate perception of key information flows, and full-element positioning of key parameters and key events. It can also filter, extract, optimize, and compress data uploaded by RTU, various sensors, or other peripherals to avoid wasting channel and terminal resources on invalid data, reduce the amount of effective information data to be uploaded, and reduce terminal device power consumption and traffic usage fees. When the Ku-band transceiver antenna 202 is a planar phased array antenna, the main control module 101 also integrates the automatic satellite search and beam control functions of the phased array antenna, which can complete the real-time tracking and pointing of the terminal to the Ku-band communication satellite.

[0044] The multi-channel water conservancy information communication terminal provided in this application also includes a power supply 106 and an interface 105. The power supply 106 is used to provide the power required by each module unit of the terminal. The interface 105 can provide a USART serial port, RS485 interface, CAN interface, WIFI interface, etc., to realize communication and control between the terminal and RTU, various sensors or other peripherals.

[0045] Please see Figure 2The main control module 101 is used to acquire water conservancy data, preprocess the water conservancy data, determine whether the preprocessed water conservancy data needs to be uploaded, set the importance level of the water conservancy data that needs to be uploaded, and evaluate the Beidou short message channel, mobile network channel and Ku-band satellite channel using the service type criterion, thereby determining the current best channel and completing the transmission of water conservancy data through the best channel.

[0046] Specifically, the main control module 101 receives or collects water conservancy data from RTUs, various sensors, or other peripherals connected to the terminal, and performs data preprocessing through water conservancy information preprocessing software. This software provides real-time data calculation and analysis for the comprehensive processing of massive amounts of water conservancy information, enabling precise perception of key information flows and full-element positioning of key parameters and events. It filters, extracts, optimizes, and compresses water conservancy data uploaded by RTUs, various sensors, or other peripherals, determines whether the data needs to be uploaded, sets an importance level for data that needs to be uploaded, and if data needs to be uploaded, the channel AI evaluation module calls upon the real-time status of each channel.

[0047] When the channel AI evaluation module calls the real-time status of each channel, it does so as follows: It starts the 5G module to collect 5G network signals, determines the 5G signal quality and whether the terminal can access the network normally, and determines whether the 5G module's transmission function is available; it starts the BeiDou-3 transceiver module to collect BeiDou information, including positioning information, accuracy, latitude, altitude, speed, number of satellites used for positioning, number of visible satellites, satellite signal quality, and UTC time, and determines whether the BeiDou-3 short message transmission function is available; it controls the Ku-band transceiver antenna 202, Ku-band radio frequency component 201, and Ku-channel water conservancy information IoT dedicated baseband module 102 to be turned on, collect Ku-channel network signals, determine the Ku-channel signal quality and whether the terminal can access the network normally, and determines whether the Ku-channel water conservancy information IoT dedicated baseband module 102's transmission function is available.

[0048] The water conservancy information preprocessing software uses a channel AI evaluation module to comprehensively evaluate the application performance of three channels—mobile network channel, BeiDou short message channel, and Ku-band satellite channel—based on a database model that considers multiple dimensions, including channel real-time status, channel transmission success rate, data type, data size, channel status, channel transmission time, channel transmission efficiency, channel transmission capacity, and channel usage cost, and determines the current optimal channel.

[0049] Traditional channel evaluation typically uses the maximum signal-to-interference-plus-noise ratio (SINR) criterion, aiming to maximize the ratio of the received power of the target channel signal to the power of the noise signal to determine the optimal channel. However, this terminal involves a wider range of frequency bands, scenarios, and technologies, making the SINR criterion insufficient for practical needs. Therefore, the channel AI evaluation module adopts the service type criterion, with the core objective of achieving an optimal match between service requirements and channel quality, bandwidth, and cost, thus achieving a good balance between accuracy, complexity, and versatility.

[0050] Please see Figure 3 The channel AI evaluation module uses the moment information of channel data and service data as input to the parameter estimation model. It models the channel using a complete service type criterion method to predict the statistical information of channel characteristics such as received power, delay, transmit power consumption, data rate and service cost. This allows it to output the optimal channel estimation parameters and ensure relatively accurate estimation results.

[0051] Finally, the data needs to be uploaded and sent through the current best channel. During the upload process, the highest-priority water conservancy data is repeatedly transmitted through all available channels to ensure reliable data upload; water conservancy data of relatively high importance is transmitted through the channel with the highest success rate; and water conservancy data of moderate importance is transmitted through the current best channel.

[0052] This application provides a multi-channel water conservancy information communication terminal that integrates 5G communication, BeiDou-3 short message communication, and Ku-band satellite communication functions. It also incorporates integrated space-ground water conservancy information processing software and a channel AI evaluation module. Through software configuration, it can automatically determine the data type of transmission, the status of each channel, and the communication cost. Furthermore, it can utilize integrated space-ground information technology to select the optimal channel and complete water conservancy information preprocessing and transmission based on the characteristics of different channels, further ensuring the efficiency, reliability, and success rate of water conservancy information transmission.

[0053] This application provides a multi-channel water conservancy information communication terminal that integrates Ku-band satellite communication, BeiDou-3 short message communication, and 5G communication, greatly improving channel availability. Through a channel AI evaluation module, it achieves intelligent optimization control of channel logic, realizing stable, secure, reliable, and cost-effective transmission of water conservancy data. Moreover, it is not limited by distance or region, effectively solving the multi-channel communication guarantee problem for various complex water conservancy projects such as hydrology, water resources, meteorology, groundwater, soil moisture, smart drainage, smart water supply, flash floods, geological disaster monitoring, and smart agriculture in remote areas and extreme conditions where ordinary signals cannot cover.

[0054] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
