Description

Technical Field

[0001] The present invention relates to the technical field of BeiDou-3 satellite short message communication, and in particular to a method and system for adapting to BeiDou-3 satellite short message communication. Background Art

[0002] Currently, when on-site equipment in power and water conservancy systems reports data to the master station, the commonly used technical means is transmission through public Internet such as 4G / 5G. Each device is equipped with a 4G / 5G wireless transmission module. When there are multiple manufacturers or different types of equipment on the field side, multiple transmission modules will be equipped to transmit data directly to the master station. This will incur repeated traffic charges.

[0003] In mountainous areas, 4G network signals are often unstable or even unavailable, making it impossible to transmit power data through public network links. This results in a lack of monitoring information on power transmission / distribution lines, construction sites, or other power facilities and equipment.

[0004] Beidou short message communication does not rely on public network signals and can provide short message communication services throughout China and surrounding areas. Its effectiveness is particularly evident in areas without public network coverage. As Beidou short message technology continues to develop, its application across various industries continues to innovate and mature. Beidou short message communication technology can solve the problem of power data communication bottlenecks in areas without signal coverage. Summary of the Invention

[0061] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of the specific embodiments of the present invention is given in conjunction with the accompanying drawings. It is obvious that the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in this field without creative work should fall within the scope of protection of the present invention.

[0062] Example 1

[0063] Reference Figure 1-Figure 3 , which is the first embodiment of the present invention, provides a method and system for adapting to BeiDou-3 satellite short message communication, including a system for adapting to BeiDou-3 satellite short message communication:

[0064] Before introducing the embodiments of the present application in detail, some related concepts are first explained for the sake of clarity.

[0065] BeiDou-3: BeiDou-3 is China's independently developed global satellite navigation system. It represents the latest phase in the development of the BeiDou satellite navigation system and was officially completed and put into operation in 2020. The BeiDou-3 system provides global positioning, navigation, and timing services, as well as regional short message communication services. This short message communication function is particularly important in areas without public network coverage, ensuring data transmission.

[0066] Beidou Short Message: Beidou Short Message Communication is a special feature of the Beidou-3 system, allowing users to send and receive short messages via Beidou satellites even when mobile network coverage is unavailable. Unrestricted by terrestrial network infrastructure, short message communication is a reliable means of communication in remote areas, offshore operations, emergency rescue, and field surveys. Short message information can include location information, emergency assistance requests, weather forecasts, and brief text messages.

[0067] Deformation monitoring and solution: Deformation monitoring and solution refers to the real-time or periodic monitoring of the physical deformation of equipment or structures in equipment deformation monitoring in the fields of electricity, water conservancy, etc., and the analysis and solution of the monitoring data through mathematical models or algorithms to determine whether the deformation of the equipment exceeds the safety threshold. Deformation monitoring and solution is one of the important functions of the edge computing unit. It can process and analyze large amounts of raw data from field equipment, reduce the amount of data through edge computing, and only transmit key solution results to the main station terminal unit via the Beidou short message link, greatly reducing the cost and complexity of data transmission. This process includes data preprocessing, deformation analysis, data compression and format conversion to meet the communication requirements of Beidou short messages. Deformation monitoring and solution plays an important role in structural safety monitoring, fault warning, and other aspects of power systems and water conservancy systems.

[0068] Beidou Card Communication Level: Beidou Card communication level refers to the maximum communication volume or capacity provided by different levels of Beidou satellite short message communication service. A Beidou Card is a device or module used for short message communication within the Beidou satellite navigation system. It allows users to send and receive short messages via Beidou satellites in areas without public network signals. This is similar to SMS but operates over the satellite network.

[0069] The communication level of a Beidou card is generally related to the following factors: Maximum communication volume: The maximum number of communication bytes or messages supported by each level of service. For example, different levels of Beidou cards may allow short messages ranging from a few thousand to several hundred thousand bytes to be sent per month. Communication rate: The speed at which the Beidou card supports sending and receiving short messages. A higher communication level theoretically allows for faster communication rates. Concurrent communication capacity: The number of communication requests that can be processed simultaneously. A higher-level Beidou card may allow for more simultaneous communication requests. Service response time: The time it takes for a Beidou card to process a communication request and return an acknowledgment. A higher-level service generally means a faster response time. Service quality: This includes indicators such as communication success rate and communication stability. Higher-level services generally provide higher-quality communication guarantees. Cost: Different communication levels have different service fees, with higher-level services generally costing more. When choosing a Beidou card, users will choose the appropriate communication level based on their needs, such as expected communication volume, communication frequency, requirements for communication speed and stability, and budget. For example, users who need to frequently send large amounts of data will choose a Beidou card with a higher communication level to meet their higher communication needs. For users who occasionally use short message communications, choosing a lower-level Beidou card can meet their needs while controlling costs.

[0070] In related technologies, there are problems such as low efficiency in processing multi-source heterogeneous data and prone to errors and losses during data transmission. Especially in complex environments where Beidou short message communication is required, the efficiency and accuracy of data encoding, decoding and transmission are particularly critical.

[0071] This application provides a method that can effectively solve the above-mentioned problems. Next, we will describe in detail how to implement the method of adapting to BeiDou-3 satellite short message communication with multiple embodiments.

[0072] Figure 1 The system structure diagram of a method and system for adapting BeiDou-3 satellite short message communication is shown, including: a data acquisition unit 100, an edge computing unit 200, a BeiDou short message unit 300, a power supply unit 400, and a master station terminal unit 500;

[0073] In the embodiment of the present application, the data acquisition unit 100 is used to obtain device reported data of devices in the target power system and water conservancy system, perform a first preprocessing on the reported data, and transmit the first preprocessed reported data to the edge computing unit 200. The first preprocessing includes at least data recognition of the reported data.

[0074] The edge computing unit 200 is used to perform edge computing according to the first preprocessed reported data transmitted by the data acquisition unit 100, and transmit the edge computing results to the Beidou short message unit 300. The edge computing at least includes performing deformation monitoring and solving on the first preprocessed reported data transmitted by the data acquisition unit 100, and the deformation monitoring and solving includes data frame format conversion;

[0075] The BeiDou short message unit 300 is used to obtain the edge computing report data transmitted by the edge computing unit 200, and undergo information encoding, encryption, pseudo code modulation, BPSK modulation and power amplification, and then undergo transmission frequency control, frequency offset correction, and power control. Finally, it is transmitted to the satellite by the transmitting antenna and forwarded by the satellite to the master station terminal unit 500;

[0076] The power supply unit 400 is used to supply power to each unit;

[0077] The master station terminal unit 500 is used to receive data transmitted from the Beidou short message unit 300.

[0078] Specifically, the data acquisition unit 100 includes: a first data acquisition module 101, a data preprocessing module 102 and a first data transmission module 103;

[0079] The first data acquisition module 101 is used to connect to the on-site equipment of the power and water conservancy systems through the data acquisition interface, periodically collect the data reported by the equipment, and transmit the data reported by the equipment to the data preprocessing module 102 and the edge computing unit 200;

[0080] The data preprocessing module 102 is used to perform a first preprocessing on the reported data transmitted by the first data acquisition module 101, filter out invalid data, identify and classify valid data, and transmit the identified and classified valid data to the first data transmission module 103;

[0081] The first data transmission module 103 is used to periodically transmit the data transmitted by the data pre-processing module 102 to the edge computing unit 200 through the internal data transmission interface;

[0082] In the embodiment of the present application, the identification classification includes a first classification of valid data by data source type, data format, and data timeliness, and a second classification of the first classification result by real-time monitoring, historical records, device status, and event data;

[0083] Transmitting the identified and classified valid data to the first data transmission module 103 includes packaging the second classification results in a preset priority structured order and transmitting them to the first data transmission module 103;

[0084] In an embodiment of the present application, the first data acquisition module 101, the data preprocessing module 102 and the first data transmission module 103 are electrically connected in a unidirectional manner in sequence, and the first data acquisition module 101, the first data transmission module 103 are bidirectionally communicatively connected to the edge computing unit 200.

[0085] In the embodiments of the present application, the periodic operations of the present application are all directly designed according to the user or operator, and are completely obtained and set based on the experience of the operator and the user, and should not be limited here.

[0086] In an optional embodiment, the data source types in the first classification include different data sources that may come from different types of equipment, such as transformers, generators, and transmission lines in power systems, and reservoirs, sluices, and pumping stations in water conservancy systems. The monitoring data of each device may have different formats and meanings, so it is necessary to distinguish the data source types for targeted processing. The data format includes multi-source heterogeneous data (that is, the device reported data of the target power system and the equipment in the water conservancy system may use different formats, such as ASCII, binary, JSON, CSV, etc.). Classifying data formats facilitates correct parsing and conversion during subsequent data processing. Data timeliness includes that the timeliness of data determines the value of the data and the priority of processing. For example, real-time monitoring data needs to be processed and transmitted immediately, while historical data can be processed later.

[0087] In an optional embodiment, real-time monitoring data in the second category requires immediate processing and transmission to ensure real-time performance. Historical records are used for analysis and statistics and do not require real-time transmission; they can be transmitted in batches during idle periods. Device status refers to device operating status data, such as device health, and is used for maintenance and predictive maintenance. Event data, including abnormal events or alarm information, requires priority processing and prompt notification to relevant personnel.

[0088] In the application embodiment, the multi-source heterogeneous data acquisition and processing module first identifies various types of data emitted by data source devices, distinguishing different data source types, data formats, and data timeliness. The data is categorized into real-time monitoring data, historical record data, device status data, and event data.

[0089] Next, prioritize. Real-time monitoring data is given the highest priority due to its time-sensitivity. Event data, particularly exception or alarm information, follows closely behind, as this information is crucial for immediate response. Device status data, used for long-term monitoring of device health, has its priority adjusted based on device importance and potential failure risk. Finally, historical record data, due to its lower real-time requirements, is given the lowest priority.

[0090] Finally, data is structured and packaged according to the aforementioned priorities. High-priority data is packaged first, while low-priority data is processed when the link is idle. Real-time monitoring data and event data should be kept to the smallest possible packet size for faster transmission. Device status data and historical records can be packaged into larger packets to reduce transmission times.

[0091] In the application embodiment, the edge computing unit 200 includes: a second data acquisition module 201, a first data storage module 202, a display module 203, an edge computing module 204 and a second data transmission module 205;

[0092] The second data acquisition module 201 is used to receive the data periodically transmitted from the first data transmission module 103 and transmit the periodic data to the first data storage module 202;

[0093] The first data storage module 202 periodically stores the original data transmitted by the first data acquisition module 101 and the processing results transmitted by the second data acquisition module 201, and transmits the stored data to the edge computing module 204;

[0094] The display module 203 is used to connect to an external display device through a VGA and HDMI interface, and retrieve the data stored in the first data storage module 202 as display data for the operation interface;

[0095] The edge computing module 204 is used to obtain the data transmitted by the first data storage module 202, and solve the obtained data, convert the solved data into a format suitable for Beidou short message transmission, and transmit it to the second data transmission module 205 at the same time;

[0096] The second data transmission module 205 transmits the acquired data in the Beidou short message transmission format to the Beidou short message unit 300 through the internal data transmission interface;

[0097] The second data acquisition module 201, the first data storage module 202, the edge computing module 204 and the second data transmission module 205 are electrically connected in sequence, and the first data storage module 202 and the display module 203 are communicatively connected;

[0098] The second data transmission module 205 is in communication with the Beidou short message unit 300 .

[0099] The edge computing module 204 includes: a data integration module 204a and a deformation monitoring and solving module 204b;

[0100] The data integration module 204a obtains the data transmitted by the first data storage module 202, integrates the data transmitted by the first data storage module 202, and transmits the integrated data to the deformation monitoring and solving module 204b;

[0101] The deformation monitoring and solving module 204b is used to solve the data after the integration operation and convert the data frame format, and transmit the data after the data frame format conversion to the Beidou short message unit 300;

[0102] The data integration module 204a and the deformation monitoring and solving module 204b are communicatively connected or electrically connected. The data integration module 204a is communicatively connected to the first data storage module 202 , and the deformation monitoring and solving module 204b is communicatively connected to the Beidou short message unit 300 .

[0103] The deformation monitoring and solving module 204b includes: a solving unit 204b-1 and a data frame format conversion unit 204b-2;

[0104] The calculation unit 204b-1 is used to perform deformation monitoring calculation on the data after the integration operation, and determine whether the monitoring threshold is exceeded based on the calculation result, and determine the conversion method of the data frame format conversion unit 204b-2 based on the calculation result;

[0105] In the embodiment of the present application, the specific solving steps of the solving unit 204b-1 are as follows:

[0106] Step 1: Data cleaning and preprocessing to remove noise and outliers from the data after integration to ensure data quality. This application uses the 3σ principle to identify and remove outliers.

[0107] If a certain integrated data point data x i Satisfy|x i -μ|>3σ, where μ is the mean and σ is the standard deviation, then x i are considered outliers.

[0108] Step 2: Baseline establishment: determine the baseline shape of the equipment under normal working conditions. Perform statistical analysis on historical data and calculate the mean and covariance matrix.

[0109] Average deformation:

[0110] where d i is the deformation value of the i-th measurement, and N is the number of measurements.

[0111] Step 3: Dynamic deformation monitoring: monitor the real-time deformation of the equipment, compare it with the baseline, and calculate the difference between the current measurement and the baseline.

[0112] Real-time deformation difference

[0113] Step 4: Deformation trend analysis, evaluate deformation trends, and predict potential failures. Use time series analysis, such as the ARIMA model, to predict future deformation. Assuming the ARIMA model is (p, d, q), the deformation prediction at time t in the future is

[0114] Step 5: Threshold judgment: determine whether the deformation exceeds the safety threshold and compare the real-time deformation difference with the preset threshold.

[0115] If |Δd|>δ, the deformation is considered to exceed the threshold, where δ is the threshold.

[0116] Step 6: Anomaly detection, identify sudden abnormal deformations, and use CUSUM control chart to detect sudden changes.

[0117] Cumulative S t =S t-1 +Δd t -K, where K is a constant, if S t >C or S t <-C, then there is an abnormality, and C is the critical value.

[0118] It should be noted that the solution unit (204b-1) needs to comprehensively consider the historical data, real-time monitoring data, deformation trends, thresholds, and anomaly detection results of the device to make an accurate judgment. Through the above steps, comprehensive monitoring and analysis of the device deformation can be achieved, ensuring that the data frame format conversion unit (204b-2) can select the optimal encoding method based on the actual situation, thereby efficiently utilizing the Beidou short message communication link for data transmission.

[0119] The data frame format conversion unit 204b-2 selects a conversion method according to the solution result of the solution unit 204b-1, performs data frame format conversion according to the conversion method, and transmits the data after the data frame format conversion to the Beidou short message unit 300;

[0120] The solving unit 204b-1 and the data frame format conversion unit 204b-2 are bidirectionally communicated or bidirectionally electrically connected;

[0121] When all the solution results in this cycle exceed the monitoring threshold, direct coding data frame format conversion is used. In the direct coding data frame format conversion, the user frame is a 5-bit protocol category, a 3-bit reserved bit, and N*8-bit service data, where N represents the bit value coefficient.

[0122] When some of the solution results exceed the monitoring threshold within this period, but not all of them exceed the monitoring threshold, the spliced ​​coded data frame format conversion is used. The spliced ​​coded data frame format conversion includes M user frames, each of which includes an 8-bit start flag, an 11-bit frame length, a 5-bit protocol type, and N*8-bit service data.

[0123] When no solution result exceeds the monitoring threshold in this cycle, the framing coding data frame format conversion is used. The framing coding data frame format conversion includes L groups of parameters, each group of parameters includes an 8-bit parameter category and an N*8-bit parameter value.

[0124] In an optional embodiment, if the user or operator does not define the monitoring threshold, when selecting the conversion method for data frame format conversion, the following method is selected by default:

[0125] When the length of the data frame to be sent does not exceed the Beidou card communication level configured by the terminal, it can be transmitted in a "direct encoding" manner, that is, the data frame to be sent is directly transmitted as "data content".

[0126] When there are multiple data frames waiting to be sent within a Beidou short message sending cycle, and the sum of the lengths of the multiple data frames (plus the length of the main frame header and checksum) does not exceed the Beidou card communication level, they can be transmitted in the "splicing encoding" mode, that is, multiple data frames to be transmitted are spliced ​​together in sequence as "data content" for transmission.

[0127] When there are too many data frames to be transmitted and the communication capacity of the Beidou terminal is seriously exceeded, or the receiver does not need all the data content but only needs some important data parameters, it can be transmitted in the "framing encoding" mode. That is, the sender parses the data frames to be transmitted, extracts some parameters to be transmitted, and reframes them in the format of "parameter type" + "DATA" according to the framing rules, and then transmits them as "data content".

[0128] When the length of the data frame to be transmitted exceeds the Beidou card communication level configured by the Beidou terminal, the data frame is divided into multiple frames according to the rules defined by the multi-frame structure and then transmitted in sequence according to the subframe number.

[0129] In an embodiment of the present application, the main frame format after format conversion includes a frame header segment, a data segment, and a check segment, and the entire frame data is arranged and transmitted in a hexadecimal format. The frame header segment consists of a frame identifier (fixed to 0xB4D2), an instruction category, a multi-frame identifier, an emergency identifier, a feedback identifier, a reserved bit, a link selection, an encoding method, a data length, a communication address, a total number of frames, and a current frame number field. The "total number of frames" and the "current frame number" are variable in content length according to the "multi-frame identifier" field indication, and the "communication address" is variable in content length according to the "link selection" field indication. The "encoding method" is divided into three types: direct encoding, splicing encoding, and framing encoding, corresponding to three different arrangement formats of "data segments". The data segment consists of a protocol category, a reserved bit, and a service data field. The "protocol category" is used to distinguish the type of protocol to which the "service data" belongs, and the "service data" is variable in length. The data segment content is encoded using three different encoding methods, based on the data source format and transmission characteristics: direct encoding, concatenated encoding, and framing encoding. (If a threshold is set, the encoding is selected based on the threshold selection method; if no threshold is set, the encoding is selected based on the length of the data frame to be sent and the Beidou card communication level configured for the terminal.) The checksum segment is the result of XORing all bytes of the header segment and the data segment in sequence. It has a fixed length of 8 bits, or 1 byte. The checksum segment is designed to ensure the accuracy of the transmitted data instruction. After the receiver receives and recognizes a complete instruction, it calculates the check digit according to the checksum calculation rules and then extracts the check digit from the instruction for comparison. If the comparison is consistent, the instruction transmission is correct. If not, it indicates that there was an error in the instruction data during transmission and the instruction is unusable.

[0130] In the embodiment of the present application, the Beidou short message unit 300 includes: a third data acquisition module 301, a digital signal processing module 302 and a sending module 303;

[0131] The third data acquisition module 301 is located in the Beidou short message unit 300, and is used to receive data converted into the Beidou short message format from the second data transmission module 205 and transmit it to the digital signal processing module 302;

[0132] After receiving the data, the digital signal processing module 302 performs signal processing tasks, including information encoding, encryption, pseudo-code modulation and BPSK modulation, converting the digital data into a signal suitable for transmission via radio waves, and transmits the signal-processed data to the sending module 303;

[0133] The transmitting module 303 is responsible for transmitting the data signal processed by the digital signal processing module 302 through the antenna, and is used to control the transmission frequency, power control and frequency offset correction to ensure that the signal is transmitted in the satellite communication link;

[0134] The third data acquisition module 301 , the digital signal processing module 302 and the sending module 303 are communicatively connected in sequence.

[0135] The main station terminal unit 500 includes: a calculation and display module 501, a comparison and judgment module 502 and a second data storage module 503;

[0136] The solution display module 501 is located in the master station terminal unit 500 and is used to receive and decode data from the Beidou short message unit 300. It is responsible for restoring the received signal to the original monitoring data and solution results, and displaying them on the monitoring screen of the master station in the form of charts or reports;

[0137] The comparison and judgment module 502 is used to analyze the data provided by the solution display module 501 and determine whether the device is in normal working condition based on the number of received data frames;

[0138] The second data storage module 503 is used to store the original data and solution results received from the edge computing unit 200, as well as the judgment results of the comparison and judgment module 502.

[0139] In an optional embodiment, the system can also include a dynamic threshold adjustment module that dynamically adjusts the monitoring threshold based on the actual communication environment and the processing capabilities of the receiving end. For example, if the receiving end detects an increase in packet loss rate or a decrease in communication channel quality, the dynamic threshold adjustment module can automatically increase the monitoring threshold to reduce transmission errors caused by excessive data volume. Conversely, if the communication environment improves or the receiving end reports an increase in processing capabilities, the monitoring threshold can be appropriately lowered to allow for the transmission of more detailed data.

[0140] Furthermore, the comparison and identification module 502 is not limited to determining the device status based on the number of data frames. It can also make intelligent judgments based on the importance and urgency of the data content. For example, if a data frame contains key parameters or abnormal alarm information, the device can be determined to be in an abnormal state even if the total number does not exceed the threshold, thereby improving the timeliness and accuracy of fault warnings.

[0141] In the master station terminal unit 500, the solution display module 501 also has a data reorganization function. When receiving data encoded using framing, it can match and reorganize parameter values ​​and parameter categories according to preset framing rules to restore the original data structure for easy understanding and use by operators.

[0142] The second data storage module 503 adopts a distributed storage architecture, which can efficiently process a large number of concurrent data storage and retrieval requests, and supports data classification, backup and recovery to ensure data security and integrity.
