[0009] A second aspect of this disclosure provides a method for receiving reservoir monitoring data, applied at a receiving end, the method comprising: The system receives short message data relayed by BeiDou satellites from the BeiDou ground station and monitors the status of the reservoir based on the short message data.

[0016] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

[0017] The accompanying drawings are provided to further illustrate the present disclosure and form part of the specification. They are used together with the following detailed description to explain the present disclosure, but do not constitute a limitation thereof.

[0020] Figure 4 This is a block diagram illustrating a reservoir monitoring system according to an exemplary embodiment. Detailed Implementation

[0021] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0022] It should be noted that all actions involving the acquisition of signals, information, or data in this disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the location is situated, and with authorization from the owner of the relevant device.

[0023] In related technologies, taking reservoir flow monitoring as an example, the following technical solutions are mainly adopted: 1. 4G / 5G Mobile Communication Solution: Water meters and flow sensors are installed at the reservoir site. Data is transmitted in real-time to the power plant's central server via a 4-20mA standard industrial signal output, processed by a telemetry terminal, and then transmitted using a 4G / 5G network. However, 4G / 5G network coverage is insufficient in remote mountainous areas, and signal strength is greatly affected by weather and terrain, frequently resulting in data transmission interruptions or delays. This affects the continuity and real-time nature of monitoring data, leading to insufficient communication reliability. Furthermore, the telemetry terminal has high power consumption, making maintenance difficult in harsh environments.

[0024] 2. BeiDou + 4G Dual-Mode Communication Scheme: This scheme uses BeiDou short message service as a backup channel, automatically switching to the BeiDou channel for data transmission when the 4G network is interrupted. This scheme has a complex system structure, requiring handling the switching logic between the two communication protocols, increasing the potential for system failures and maintenance difficulty.

[0025] 3. Wired communication solution: Using fiber optic or wired networks for data transmission in reservoirs with suitable conditions is difficult to construct and has regional limitations.

[0026] In view of this, the present disclosure provides a method for transmitting and receiving reservoir monitoring data, as well as a reservoir monitoring system, to solve the above-mentioned technical problems.

[0027] Figure 1This is a flowchart illustrating a method for transmitting reservoir monitoring data according to an exemplary embodiment. The method is applied at the transmitting end, such as... Figure 1 As shown, the method includes: S101: Acquire the first monitoring data collected by the target sensor set up in the reservoir.

[0028] This disclosure provides a reservoir monitoring system, such as... Figure 2 As shown, it includes a data acquisition and transmission system, a data transmission network, and a data receiving and processing system, wherein the data acquisition and transmission system is equivalent to the sending end, and the data receiving and processing system is equivalent to the receiving end.

[0029] Optionally, the target sensor is a flow sensor, and the first monitoring data is the water flow rate value.

[0030] The target sensor can be a flow sensor, such as an industrial water meter installed at the reservoir outlet, where the first monitoring data is the water flow rate. Optionally, the target sensor can also be a sensor used to collect information such as water level, rainfall, and water quality. By using multiple different types of sensors, a multi-dimensional comprehensive reservoir monitoring system can be constructed, and this disclosure does not impose any limitations on this.

[0031] S102: Convert the first monitoring data into binary format data, and encapsulate the binary format data into short message data according to the preset BeiDou short message format.

[0032] For example, binary format data can be a custom binary frame structure. Assume a frame contains a device ID, timestamp, flow rate value, battery voltage, and a CRC (Cyclic Redundancy Check) checksum. Specifically, the frame header can be a fixed value used to identify the start of a data frame; the device ID is a unique identifier for the target sensor; the timestamp is the timestamp of data acquisition; the flow rate value is the processed core data; the battery voltage is the battery voltage of the target sensor; the CRC checksum is used to verify whether data errors occurred during transmission; and it can also include a status word, for example, using each bit to represent different device states (e.g., 0 - normal communication, 1 - other), etc. The specific configuration can be set according to requirements, and this disclosure does not impose any limitations on this.

[0033] S103: The short message sending module sends short message data to the Beidou satellite so that the receiving end can obtain the short message data from the Beidou satellite and monitor the status of the reservoir based on the short message data.

[0034] For example, such as Figure 2As shown, the short message sending module can use the BeiDou-3 RDSS module, which supports short message communication. The communication frequency is 1 second / time, and the length of a single message is 140 bytes. The specific value can be determined according to requirements, and this disclosure does not impose any restrictions. Therefore, data collection and transmission can be performed without being limited by geographical environment.

[0035] Accordingly, such as Figure 2 As shown, the BeiDou satellite network can use the short message communication service of the BeiDou-3 system to realize data transmission from the reservoir site to the thermal power plant. The BeiDou ground station can receive the short message data forwarded by the satellite and transmit it to the BeiDou receiving terminal through a dedicated network.

[0036] By using the above method, the binary format data after processing the reservoir monitoring data is sent through the BeiDou short message format. On the one hand, reliable data transmission is achieved in the unstable 4G / 5G signal environment. On the other hand, the data payload is effectively optimized, thereby improving the communication reliability and data availability of the reservoir monitoring system and enhancing the scientificity and timeliness of water resource scheduling.

[0037] In one possible manner, acquiring first monitoring data collected by a target sensor installed in the reservoir includes: acquiring current signal data collected by the target sensor installed in the reservoir; converting the current signal data into voltage signal data; converting the voltage signal data into initial monitoring data in digital signal form using an analog-to-digital converter; and obtaining the first monitoring data based on the initial monitoring data.

[0038] For example, such as Figure 2 As shown, the target sensor is a flow sensor, such as an industrial water meter that outputs a standard 4-20mA current signal, corresponding to a flow range of 0-1000 m³ / h. The flow sensor can be used to collect the outflow rate of the reservoir in real time.

[0039] For example, such as Figure 2 As shown, a signal conditioning module employing a high-precision current sampling circuit can convert a 4-20mA current signal into a 0-3.3V voltage signal, achieving a resolution of 16 bits and a sampling accuracy of ±0.1%.

[0040] For example, such as Figure 2 As shown, the microcontroller unit performs digital acquisition through a digital-to-analog converter (ADC). The microcontroller unit can employ a low-power chip core with a main frequency of 80MHz and a built-in 12-bit ADC for signal acquisition.

[0041] The above conversion process, for example, can replace the 4-20mA signal with industrial standard signals such as 0-10V and RS485, and the microcontroller unit can be other low-power microcontroller units, etc. The specific selection can be made according to the requirements, and this disclosure does not impose any restrictions on it.

[0042] Thus, by converting current signals into digital signals with high precision, the accuracy of the acquired data can be guaranteed.

[0043] In one possible manner, obtaining the first monitoring data based on the initial monitoring data includes: performing at least one of the following data processing operations on the initial monitoring data: filtering, calibration, and compression, to obtain the first monitoring data.

[0044] For example, such as Figure 2 As shown, the microcontroller unit performs at least one of the following data processing steps on the collected initial monitoring data: filtering, calibration, and compression, to obtain optimized first monitoring data.

[0045] Among them, the filtering process can adopt the moving average filtering method. The microcontroller unit continuously collects multiple ADC sample values, removes the maximum and minimum values, and takes the arithmetic mean of the remaining sample values ​​as the effective sample value, thereby effectively smoothing the data and improving stability.

[0046] For example, the calibration process can employ a two-point calibration method, such as storing calibration parameters in the microcontroller unit, including the theoretical zero point, the theoretical full scale, and the calibration calculation formula. For instance, the theoretical zero point is the ADC value corresponding to a 4mA current signal, the theoretical full scale is the ADC value corresponding to a 20mA current signal, and the calibration calculation formula is: actual flow rate (m³ / h) = (current ADC sample value - theoretical zero point) / (theoretical full scale - theoretical zero point) × 1000, etc. This disclosure does not limit this.

[0047] For example, compression can employ adaptive data compression techniques to increase the data capacity of a single message. For instance, the calculated floating-point flow value can be mapped proportionally to a 12-bit integer and then stored in 1.5 bytes, thus achieving data "compression" or "simplification".

[0048] In related technologies, raw, unprocessed or simply encapsulated data is typically transmitted, or the entire file is transmitted directly. This results in redundant data formats and reliance on a stable, high-bandwidth network. In contrast, this disclosure transmits data that has undergone filtering, noise reduction, precise calibration, and highly simplified encoding. This adapts to the extremely low bandwidth and pay-as-you-go nature of BeiDou short messages, optimizing the data payload for specific channels and enabling the transmission of more information within a limited message length.

[0049] In one possible approach, binary format data is encapsulated into short message data according to a preset BeiDou short message format. This includes: splitting the binary format data into multiple data fragments, each fragment corresponding to a fragment number; and encapsulating each fragment according to the BeiDou short message format to obtain multiple fragmented short message data. The short message data is then sent to the BeiDou satellite via a short message sending module, including: sending the multiple fragmented short message data to the BeiDou satellite via the short message sending module.

[0050] In this embodiment of the disclosure, for large data volumes, a multi-packet fragmentation transmission protocol can be used for fragmented transmission, and the complete data can be automatically reassembled at the receiving end, thereby realizing large data transmission.

[0051] For example, the sending end divides the large data block to be sent into multiple message fragments according to the maximum effective payload. Each fragment message contains a unique message identifier, the current fragment sequence number, the total number of fragments, and other control information. The fragmented messages are sent sequentially. The receiving end verifies each received fragment and may confirm it by replying with an ACK. After collecting all fragments, the receiving end reassembles them into complete data according to the fragment sequence number before performing subsequent parsing processing.

[0052] For example, when communication is briefly interrupted due to signal obstruction or other reasons, the sending end will buffer the unsuccessfully transmitted data in its local non-volatile memory. Once communication is restored, the backlog of historical data is packaged into batches and transmitted to the receiving end via multi-packet fragmentation. The receiving end reassembles the data based on fragment sequence numbers, total fragment counts, and other information to ensure zero data loss. Alternatively, a low-power intermittent operating mode can be used, where the sending end gathers multiple data records collected over a period of time (e.g., 1 hour) and transmits them to the receiving end all at once via multi-packet fragmentation. Furthermore, it can also be used to transmit device diagnostic logs, operational status records, or remote configuration parameters that exceed the capacity of a single packet.

[0053] In addition, this disclosure also provides an error control mechanism, namely, a CRC16 checksum and retransmission mechanism. For example, if the short message data fails the checksum verification, the short message data is retransmitted to ensure the reliability of data transmission.

[0054] Figure 3 This is a flowchart illustrating a method for receiving reservoir monitoring data according to an exemplary embodiment. The method is applied at the receiving end, such as... Figure 3 As shown, the method includes: S301: Receives short message data relayed by BeiDou satellites from the BeiDou ground station and monitors the reservoir's status based on the short message data.

[0055] The short message data is determined by the sending end in the following manner: acquiring the first monitoring data collected by the target sensor set in the reservoir; converting the first monitoring data into binary format data, and encapsulating the binary format data into short message data according to the preset BeiDou short message format; and sending the short message data to the BeiDou satellite through the short message sending module.

[0056] For example, such as Figure 2 As shown, the short message data forwarded by the Beidou ground station can be received by the Beidou receiving terminal in the receiving end, and the short message data can be parsed by the data parsing server to monitor the status of the reservoir based on the short message data.

[0057] Among possible methods, reservoir monitoring based on short message data includes: parsing binary format data in short message data to obtain structured data; converting the structured data to obtain second monitoring data in JSON format; and displaying the second monitoring data through a visualization interface to monitor the reservoir's status.

[0058] For example, such as Figure 2 As shown, dedicated data parsing software can run on the data parsing server to parse binary data byte by byte and bit by bit according to a predefined frame structure protocol. In the server's memory, the data transforms from a one-dimensional byte stream into a structured data object containing a series of fields with clearly defined names and types, such as the device ID, timestamp, traffic value, battery voltage, and CRC checksum mentioned above, thus obtaining structured data. Furthermore, the structured data object in the server's memory is serialized into a standard JSON string, such as the JSON string "Device ID: xx; Timestamp: xx-xx-xx; Traffic Value: xxx;...", etc.

[0059] Transmitting binary data and then converting it to JSON format avoids introducing a large number of redundant characters compared to directly transmitting metadata or performing format conversion at the sending end. It allows more effective data to be carried within a limited number of bytes, balancing transmission efficiency and system integration convenience.

[0060] In one possible manner, receiving short message data relayed by BeiDou satellites from a BeiDou ground station includes: receiving multiple fragmented short message data relayed by BeiDou satellites from the BeiDou ground station. These fragmented short message data are obtained by the sending end splitting binary format data into multiple fragments and encapsulating each fragment according to the BeiDou short message format, with each fragment corresponding to a fragment number; parsing the multiple fragmented short message data to obtain multiple fragmented data; and assembling the multiple fragmented data into binary format data according to the fragment number corresponding to each fragment.

[0061] If the sending end uses a multi-packet fragmentation method for data transmission, the receiving end collects all fragments, reassembles them into complete binary format data according to the fragment sequence number, and then performs subsequent parsing processing.

[0062] For example, if one of the fragmented short message data is not received and the verification fails, the sender can be requested to resend the fragmented short message data; this disclosure does not impose any restrictions on this. This enables the transmission of large amounts of data.

[0063] Figure 4 This is a structural block diagram of a reservoir monitoring system according to an exemplary embodiment, such as... Figure 4 As shown, the reservoir monitoring system 40 includes a transmitter 41 and a receiver 42. The transmitter 41 includes a first data processing unit 411, a short message sending module 412, and a target sensor 413 installed in the reservoir. The receiver 42 includes a short message receiving module 421 and a second data processing unit 422. The target sensor 413 is used to collect first monitoring data of the reservoir. The first data processing unit 411 is used to convert the first monitoring data into binary format data and encapsulate the binary format data into short message data according to the preset BeiDou short message format. The short message sending module 412 is used to send the short message data to the BeiDou satellite. The short message receiving module 421 is used to receive the short message data forwarded by the BeiDou satellite from the BeiDou ground station. The second data processing unit 422 is used to monitor the status of the reservoir based on the short message data.

[0064] For example, such as Figure 2 As shown, the transmitting end 41 is the data acquisition and transmission system, and the receiving end 42 is the data reception and processing system. The reservoir monitoring system 40 may not include a data transmission network, but may use the existing BeiDou satellite network and BeiDou ground stations for data transmission. This disclosure does not impose any restrictions on this.

[0065] For example, such as Figure 2 As shown, the first data processing unit 411 includes a signal conditioning module and a microcontroller unit. Taking the target sensor as the flow sensor, the signal conditioning module can convert the 4-20mA standard current signal output by the flow sensor into a 0-3.3V voltage signal. Then, the microcontroller unit performs digital acquisition through a digital-to-analog converter to obtain a digital signal, that is, the first monitoring data can be the water flow value.

[0066] For example, such as Figure 2 As shown, the short message receiving module 421 is the BeiDou receiving terminal, and the second data processing unit 422 is the data parsing server. Dedicated data parsing software can run on the data parsing server to parse binary format data byte by byte and bit by bit according to a predefined frame structure protocol, and serialize it into a standard JSON string.

[0067] It achieves end-to-end format conversion from 4-20mA to JSON format, which facilitates integration with subsequent data analysis systems.

[0068] For example, the reservoir monitoring system 40 also includes a database server that can store JSON data, including JSON data corresponding to historical collected data, to support data querying and statistical analysis.

[0069] In addition, the reservoir monitoring system 40 also includes a monitoring and display system, such as converting the above-mentioned JSON data into chart data and displaying it in a visualization interface. For example, it can display the real-time flow data of the reservoir, support historical data query and data trend analysis, etc. This disclosure does not limit this.

[0070] In one possible configuration, the transmitter is powered by a 12V / 20Ah lithium battery, which is charged by solar energy.

[0071] like Figure 2 As shown, the transmitter 41 also includes a voltage management module, which can use a solar charge controller + 12V / 20Ah lithium battery to power the various modules of the transmitter, resulting in low power consumption and ensuring long-term stable operation of the system.

[0072] The above technical solution utilizes BeiDou satellite communication, which is not limited by terrestrial network coverage and can still transmit data normally even when 4G / 5G signals are unstable or interrupted. Furthermore, it focuses on BeiDou short message communication, avoiding complex dual-mode switching logic and reducing system complexity and failure rate. BeiDou short message communication has low latency, meeting real-time monitoring requirements. Moreover, the BeiDou system has a wide coverage area, suitable for reservoir monitoring in various geographical environments.

[0073] Among other possible implementation methods, BeiDou short message service can be replaced by other wireless communication technologies such as maritime satellite communication, and this disclosure does not impose any restrictions on this.

[0074] In other possible implementation methods, edge computing capabilities can be added to the receiving end to achieve data preprocessing, anomaly detection, and intelligent alarm functions. For example, an alarm can be triggered if the water flow is lower than a preset value, or if the water level is lower than a first preset value or higher than a second preset value, etc. This disclosure does not limit this. Model services can also be introduced to perform intelligent data analysis, realizing intelligent functions such as predicting reservoir flow and providing anomaly warnings.

[0075] Among other possible implementation methods, multiple receivers can be supported to receive data simultaneously, thereby improving the redundancy and reliability of the system.

[0076] In other possible implementations, the sending end adopts an intermittent working mode, with the system in a dormant state most of the time, and is woken up periodically to collect and send data.

[0077] In other possible implementations, the transmitter can be designed as a mobile monitoring device to suit temporary monitoring tasks and emergency monitoring scenarios.

However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0079] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0080] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
