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 BeiDou-3 satellite short message communication. Background Art

[0002] Currently, when the on-site equipment in the power and water conservancy systems reports data to the master station, the commonly used technical means is to transmit through the 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 missing 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 in China and surrounding areas, especially in areas without public network signal coverage. With the continuous development of Beidou short message technology, its promotion and application in various industries has also been continuously innovated and gradually matured. Beidou short message communication technology can solve the problem of poor communication of power data in areas without signals. Summary of the invention

[0061] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings of the specification. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in the art without creative work should fall within the scope of protection of the present invention.

[0062] Example 1

[0063] Reference Figure 1-Figure 3 , is the first embodiment of the present invention, which 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 describing 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 a global satellite navigation system independently developed by China. It is the latest stage of the development of the BeiDou satellite navigation system and was officially completed and put into use in 2020. The BeiDou-3 system provides global positioning, navigation, timing services, and regional short message communication services. Especially in areas without public network signal coverage, the BeiDou short message communication function is particularly important and can ensure data transmission.

[0066] Beidou short message: Beidou short message communication is a special service in the Beidou-3 system, allowing users to send and receive short messages through Beidou satellites when there is no mobile network signal. Short message communication is not restricted by ground network infrastructure, so it has become a reliable means of communication in remote areas, offshore operations, emergency rescue, field surveys and other scenarios. Short message information can include location information, emergency assistance information, weather forecasts, short text messages, etc.

[0067] Deformation monitoring and solution: Deformation monitoring and solution refers to the real-time or periodic monitoring of the physical deformation of equipment or structure in the deformation monitoring of equipment 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 a large amount of raw data from field equipment, reduce the amount of data through edge computing, and only transmit the key solution results to the main station terminal unit through the Beidou short message link, which greatly reduces 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 communication capacity that different levels of services can provide in Beidou satellite short message communication service. Beidou Card is a device or module used for short message communication service in Beidou satellite navigation system. It allows users to send and receive short messages through Beidou satellite in areas without public network signals, similar to SMS service but through satellite network.

[0069] The communication level of Beidou card is usually related to the following factors: Maximum communication volume: the maximum number of communication bytes or information supported by each level of service. For example, Beidou cards of different levels may allow the sending of short messages of several thousand to several hundred thousand bytes per month. Communication rate: the speed at which short messages are sent and received supported by Beidou card. The higher the communication level, the faster the communication rate may be theoretically. Concurrent communication capability: the number of communication requests that can be processed at the same time. A high-level Beidou card may allow more communication requests to be processed simultaneously. Service response time: the time it takes for Beidou card to process a communication request and return a confirmation. A high-level service usually means a shorter response time. Service quality: including indicators such as communication success rate and communication stability. High-level services usually provide higher-quality communication guarantees. Cost: The service costs of different communication levels are different, and high-level services are usually more expensive. When choosing a Beidou card, users will choose the appropriate communication level based on their own needs, such as the expected communication volume, communication frequency, requirements for communication speed and stability, and budget. For example, for users who need to send large amounts of data frequently, they will choose a Beidou card with a higher communication level to meet 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 easy errors and losses during data transmission. Especially in complex environments where Beidou short message communications are required, the efficiency and accuracy of data encoding, decoding and transmission are particularly critical.

[0071] The present application provides a method that can effectively solve the above-mentioned problems. Next, a method for adapting to the Beidou-3 satellite short message communication will be described in detail in combination 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 the device reported data of the equipment in the target power system and the water conservancy system, and perform a first preprocessing on the reported data, and transmit the first preprocessed reported data to the edge computing unit 200, and the first preprocessing at least includes data identification 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 result to the Beidou short message unit 300, wherein 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 reported data after edge computing 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 deviation correction, and power control, and finally transmitted to the satellite by the transmitting antenna, and forwarded to the master station terminal unit 500 by the satellite;

[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 equipment reported data, and transmit the equipment reported data 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 preprocessing 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 classification;

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

[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 sequence in one direction, and the first data acquisition module 101, the first data transmission module 103 are bidirectionally communicated with the edge computing unit 200.

[0085] In the embodiments of the present application, the periodic operations of the present application are directly designed according to the user or operator, and are completely acquired 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, pumping stations, etc. 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, the real-time monitoring data in the second category needs to be processed and transmitted immediately to ensure real-time performance. Historical records are used for analysis and statistics, and do not need to be transmitted in real time. They can be transmitted in batches during idle time periods. Equipment status is the operating status data of the equipment, such as the health status of the equipment, which is used for equipment maintenance and predictive maintenance. Event data is abnormal events or alarm information, which needs to be processed first and notified to relevant personnel quickly.

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

[0089] Secondly, determine the priority. Real-time monitoring data is given the highest priority because it is most time-sensitive. Event data, especially abnormal or alarm information, follows closely because this information is critical for immediate response. Equipment status data is used to monitor the health of equipment over a long period of time, and its priority is adjusted according to the importance of the equipment and the potential risk of failure. Finally, historical record data is given the lowest priority because it has a lower requirement for real-time performance.

[0090] Finally, data is packaged in a structured manner according to the above priorities. High-priority data is packaged first, and low-priority data is processed when the link is idle. Real-time monitoring data and event data should be kept as small as possible for fast transmission. Device status data and historical record data can be packaged into larger data packets to reduce the number of transmissions.

[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 of 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 in communication connection;

[0098] The second data transmission module 205 is in communication connection 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 judge whether it exceeds the monitoring threshold according to the calculation result, and determine the conversion method of the data frame format conversion unit 204b-2 according to 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, remove noise and outliers from the data after integration operation 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 ith 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 trend, threshold value and abnormal detection results of the equipment to make an accurate judgment. Through the above steps, comprehensive monitoring and analysis of the deformation of the equipment can be achieved, ensuring that the data frame format conversion unit (204b-2) can select the optimal encoding method according to the actual situation, thereby efficiently using 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 there are solution results exceeding the monitoring threshold in this cycle, 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 category, and N*8-bit service data;

[0123] When there is no solution result exceeding the monitoring threshold in this cycle, the framing coding data frame format conversion is used, and 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 the 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 they seriously exceed the communication capacity of the Beidou terminal, or the receiver does not need all the data content but only needs some important data parameters, they 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, re-frames 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 transmitted in sequence according to the subframe number.

[0129] In the 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 whole 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, wherein the "total number of frames" and the "current frame number" indicate that the content length is variable according to the "multi-frame identifier" field, and the "communication address" indicates that the content length is variable according to the "link selection" field. 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" can be variable in length. The data segment content is designed with three different encoding methods according to the data source format and transmission characteristics: direct encoding, splicing encoding, and framing encoding (if a threshold is set, it is selected according to the threshold selection method; if no threshold is set, it is selected according to the length of the data frame to be sent and the Beidou card communication level configured by the terminal). The check segment is the result of XORing all the byte data of the frame header segment and the data segment in sequence, with a fixed length of 8 bits, i.e. 1 byte. The check segment is to ensure the accuracy of the transmitted data instruction. After the receiver receives and recognizes a complete instruction, it calculates the check bit according to the check calculation rules, and then extracts the check bit in the instruction for comparison. If the comparison is consistent, it means that the instruction transmission is correct. If it is inconsistent, it means that there is an error in the instruction data during transmission and the instruction is unavailable.

[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, converts 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 sending 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 deviation 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, and 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 determination module 502 is used to analyze the data provided by the solution display module 501, and determine whether the device is in a normal working state according to 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 may also be provided with a dynamic threshold adjustment module, which may dynamically adjust the monitoring threshold according to the actual communication environment and the processing capability of the receiving end. For example, when it is detected that the packet loss rate of the receiving end increases or the quality of the communication channel decreases, the dynamic threshold adjustment module may automatically increase the monitoring threshold to reduce transmission errors caused by excessive data volume. Conversely, when the communication environment improves or the receiving end reports that its processing capability has increased, the monitoring threshold may be appropriately lowered to send more detailed data.

[0140] In addition, the comparison and discrimination module 502 is not limited to judging the device status based on the number of data frames, but can also make intelligent judgments based on the importance and urgency of the data content. For example, if the data frame contains key parameters or abnormal alarm information, even if the total number does not exceed the threshold, it can be determined that the device is in an abnormal state, so as to improve the timeliness and accuracy of fault warning.

[0141] In the main 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.

[0143] In summary, the present invention proposes a method and system for adapting to the short message communication of Beidou-3 satellite, obtains the first real-time monitoring data of different target devices, and performs data identification on the first real-time monitoring data to obtain the second real-time monitoring data, wherein the first real-time monitoring data format of the different target devices is a multi-source heterogeneous data format; performs a second preprocessing on the second real-time monitoring data after data identification, and combines the preset Beidou short message frame format conversion logic to obtain the third real-time monitoring data after the Beidou short message frame format conversion, wherein the second preprocessing at least includes edge computing operations; solves the third real-time monitoring data, and transmits the solved third real-time monitoring data back to the target terminal through the Beidou link.
