[0008] The real-time dynamic differential broadcasting platform is configured to receive and store the sensing data sent by the IoT sensing terminal, and in response to receiving a data request instruction sent by the IoT platform, transmit the target sensing data corresponding to the data request instruction to the IoT platform.

[0009] The IoT platform is configured to send a data request instruction, so that the real-time dynamic differential broadcasting platform can send the sensing data after receiving the data request instruction, and receive the target sensing data sent by the real-time dynamic differential broadcasting platform, so that the IoT platform can monitor the target sensing data.

[0024] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0025] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this disclosure should have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms "first," "second," and similar terms used in the embodiments of this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

[0026] The following are definitions of terms used in this disclosure:

[0027] RTK technology: Real-time kinematic (RTK) means real-time dynamic differential. Differential refers to using ground base stations to resolve calibration errors. Based on real-time processing of the carrier phase of two stations, it utilizes dual-frequency (L1 and L2 receiving frequencies) and dual-differential (station-to-station differential, satellite differential) signals from ground and airborne receivers to eliminate transmission errors and receiver errors, thereby achieving extremely high positioning accuracy, typically within 2-3 centimeters for position and altitude measurements.

[0028] RTCM Protocol: RTCM (the Radio Technical Commission for Maritime Services) is a widely adopted data transmission format. It was proposed by the Radio Technical Commission for Maritime Services to develop standards for use in differential global navigation and positioning systems and real-time dynamic operations.

[0029] RTK Broadcast Platform: A real-time dynamic differential broadcast platform, a centimeter-level differential data broadcast system based on RTK technology, providing stable differential assurance to meet the high-precision navigation and positioning needs of various industries.

[0030] Ntrip, short for Networked Transport of RTCM via Internet Protocol, is an internet-based real-time data transmission protocol. It is primarily used to transmit differential GNSS (Global Navigation Satellite System) data, such as RTCM SC-104 format data. The Ntrip protocol achieves real-time transmission and sharing of differential data by establishing a communication network between base stations, servers, and user equipment. It is mainly used for transmitting real-time differential GNSS data, such as RTCM and CMR formats, over the internet.

[0031] The BeiDou Navigation Satellite System consists of three parts: the space segment, the ground segment, and the user segment. It can provide high-precision, high-reliability positioning, navigation, and timing services to various users around the world, 24 / 7, and also has short message communication capabilities.

[0032] Internet of Things (IoT) technology refers to connecting any object to a network through information sensing devices and according to agreed protocols. Objects exchange and communicate information through information transmission media to achieve functions such as intelligent identification, positioning, tracking, and monitoring.

[0033] With the completion and development of the BeiDou Navigation Satellite System and the mature application of Internet of Things (IoT) technology, BeiDou technology and IoT technology have been widely used in agriculture, transportation, surveying and mapping, and the power industry.

[0034] These applications involve tens of thousands of terminal devices, which simultaneously connect to a real-time dynamic differential broadcast platform to obtain high-precision location data and to an IoT platform to report sensing data. In this scenario, the terminal devices need to handle authentication and authorization processes for both platforms concurrently, increasing resource consumption such as memory, network bandwidth, and data traffic.

[0035] refer to Figure 1 According to one embodiment of this application, the data transmission system includes an IoT sensing terminal, a real-time dynamic differential broadcasting platform, and an IoT platform connected in sequence. The real-time dynamic differential broadcasting platform is a BeiDou RTK data broadcasting platform.

[0036] The IoT sensing terminal 101 is configured to acquire sensing data and send the sensing data to the real-time dynamic differential broadcasting platform 102. The sensing data is IoT sensing data, which typically includes real-time data from various sensors. For example, the sensing data may be temperature, humidity, pressure, or light intensity.

[0037] Specifically, Figure 2 This is a schematic diagram of the architecture of the data transmission system according to an embodiment of the present disclosure, such as... Figure 2 As shown, the IoT sensing terminal 101 processes and packages the sensing data, and then transmits it to the real-time dynamic differential broadcasting platform 102 via the NTRIP protocol. The NTRIP protocol was originally designed for GNSS differential data transmission, but its TCP / IP-based communication mechanism and flexible data processing capabilities make it suitable for transmitting IoT sensing data.

[0038] The real-time dynamic differential broadcasting platform 102 is configured to receive and store the sensing data sent by the IoT sensing terminal 101. In response to receiving a data request instruction from the IoT platform 103, it transmits the target sensing data corresponding to the data request instruction to the IoT platform 103.

[0039] Specifically, after receiving the sensing data sent by the IoT sensing terminal 101, the real-time dynamic differential broadcasting platform 102 stores the sensing data in the database.

[0040] When the real-time dynamic differential broadcast platform 102 receives a data request instruction from the IoT platform 103, it indicates that the IoT platform 103 needs to acquire the sensing data of the IoT sensing terminal 101 and transmit the target sensing data corresponding to the data request instruction to the IoT platform 103. The data request instruction typically includes necessary authentication information, request parameters (such as device ID, time range, etc.), and request type (such as acquiring terminal device information, real-time location data, etc.).

[0041] The IoT platform 103 is configured to send a data request instruction, so that the real-time dynamic differential broadcasting platform 102 can send the sensing data after receiving the data request instruction, and receive the target sensing data sent by the real-time dynamic differential broadcasting platform 102, so that the IoT platform 103 can monitor the target sensing data.

[0042] Specifically, when generating a data request instruction, the IoT platform 103 sends the data request instruction to the real-time dynamic differential broadcasting platform 102 through the connected client or adapter in accordance with the interface specification. The data request instruction includes authentication information, request parameters, and request type.

[0043] The Internet of Things platform 103 receives the target perception data sent by the real-time dynamic differential broadcasting platform 102, and realizes intelligent identification, positioning, tracking and monitoring functions of the target perception data.

[0044] In some embodiments, the data determination module further includes:

[0045] The instruction verification unit is configured to receive a data request instruction sent by the IoT platform 103, verify the data request instruction, and in response to successful verification, determine the target response data corresponding to the data request instruction and send the target response data to the transmission module.

[0046] Specifically, after receiving a data request instruction from the IoT platform 103, the real-time dynamic differential broadcasting platform 102 first verifies the identity of the IoT platform 103 and the request parameters based on the authentication information and request parameters in the data request instruction. After successful verification, the real-time dynamic differential broadcasting platform 102 determines the corresponding target sensing data according to the request type and request parameters, and sends the target sensing data to the IoT platform 103.

[0047] Meanwhile, after successful verification, the real-time dynamic differential broadcasting platform 102 can also retrieve the corresponding terminal device information from the database according to the request type, and encapsulate the terminal device information into a response data packet and send it to the Internet of Things platform 103.

[0048] The data transmission system, as described above, comprises an IoT sensing terminal 101, a real-time dynamic differential broadcasting platform 102, and an IoT platform 103 connected in sequence. The IoT platform 103 obtains the sensing data from the IoT sensing terminal 101 through the real-time dynamic differential broadcasting platform 102. While ensuring normal data transmission, the IoT sensing terminal 101 only needs to connect to the real-time dynamic differential broadcasting platform 102, reducing resource consumption such as terminal memory, network bandwidth, and data traffic. Furthermore, the IoT sensing terminal 101 only needs to manage the authentication information of the real-time dynamic differential broadcasting platform 102, reducing the risk of information leakage or misuse.

[0049] Meanwhile, reducing the development and maintenance of authentication and authorization logic for a single platform will decrease the complexity of the terminal device system. The IoT Sensing Terminal 101 only needs to handle authentication and authorization for one platform, including protocols, interfaces, and error handling. Users do not need to switch between different platforms, reducing the complexity of the operation process and improving the user experience. Developers of the IoT Sensing Terminal 101 only need to develop and maintain authentication and authorization for one platform, reducing development, testing, and maintenance resources, lowering the overall R&D cost, and shortening the development cycle.

[0050] Furthermore, the IoT sensing terminal 101 only needs to handle the fault recovery and reconnection logic of one platform, reducing the complexity of system fault handling. The IoT sensing terminal 101 only needs to integrate data and status information from one platform, avoiding inconsistencies in data formats or standards between the two platforms, thus reducing the difficulty and cost of data integration.

[0051] When installing the IoT sensing terminal 101, only the connection information of one platform needs to be configured and tested, reducing installation difficulty and the risk of device installation failure. Single-platform data linking will reduce the power consumption of the IoT sensing terminal 101, allowing for a smaller battery capacity under the same requirements. This will also reduce design complexity.

[0052] In some embodiments, the IoT sensing terminal 101 specifically includes:

[0053] The data processing module is configured to acquire sensing data, convert the sensing data into a format to obtain sensing data in a target format, and send the sensing data in the target format to the data transmission module, wherein the target format is the format corresponding to the real-time differential data protocol.

[0054] Specifically, in this embodiment, the target format is a data format supported by the NTRIP protocol. Specifically, the data processing module converts the sensed data into a data format supported by the NTRIP protocol or encapsulates it, and then transmits it via the NTRIP protocol.

[0055] The data transmission module is configured to receive the target format perception data sent by the data processing module and send the target format perception data to the real-time dynamic differential broadcasting platform 102.

[0056] After receiving the sensing data in the target format sent by the data processing module, the data transmission module relays and distributes it through NTRIPCaster. NTRIPCaster then forwards this data to the platform or users who have subscribed to the data.

[0057] In some embodiments, the data transmission module specifically includes:

[0058] The encryption unit is configured to receive the target format sensing data sent by the data processing module, encrypt the target format sensing data to obtain encrypted sensing data, and send the encrypted sensing data to the transmission unit.

[0059] The transmission unit is configured to receive the encrypted sensing data sent by the encryption unit and send the encrypted sensing data to the real-time dynamic differential broadcasting platform 102.

[0060] Specifically, when transmitting sensing data in the target format to the real-time dynamic differential broadcasting platform 102, the IoT sensing terminal 101 can encrypt the sensing data in the target format to obtain encrypted sensing data, and then send the encrypted sensing data to the transmission unit. The transmission unit then sends the encrypted sensing data to the real-time dynamic differential broadcasting platform 102.

[0061] In this embodiment, the encryption algorithm used for encryption processing can be either a symmetric or asymmetric. In a symmetric encryption algorithm, only one key is used, and both the sender and receiver use this key to encrypt and decrypt the data. Asymmetric encryption algorithms, also known as public-key encryption algorithms, require two keys: a public key and a private key. In this embodiment, the encryption algorithm used for encryption processing is not limited.

[0062] Accordingly, after receiving the encrypted sensing data, the real-time dynamic differential broadcasting platform 102 needs to verify and decrypt the encrypted sensing data to obtain the sensing data in the target format. It is understood that the decryption algorithm corresponds to the encryption algorithm. Through the above encryption and decryption processes, the security and integrity of data between the IoT sensing terminal 101 and the real-time dynamic differential broadcasting platform 102 during transmission are ensured.

[0063] In some embodiments, the real-time dynamic differential broadcasting platform 102 includes:

[0064] The data determination module is configured to receive a data request instruction sent by the IoT platform 103, determine the target response data corresponding to the data request instruction, and send the target response data to the transmission module.

[0065] The transmission module is configured to receive target response data sent by the data encapsulation module and transmit the target response data to the Internet of Things platform 103.

[0066] Specifically, after receiving a data request instruction from the IoT platform 103, the real-time dynamic differential broadcast platform 102 determines the request parameters and request type contained in the data request instruction, and then determines the target response data based on the request parameters and request type. The target response data is then sent to the transmission module, which in turn sends it to the IoT platform 103.

[0067] Specifically, the data determination module includes:

[0068] The data lookup unit is configured to look up the target perception data corresponding to the data request instruction and send the target perception data to the data encapsulation unit.

[0069] The data encapsulation unit is configured to encapsulate the target perception data to obtain target response data.

[0070] The real-time dynamic differential broadcasting platform 102 searches the database based on the request type and request parameters to determine the target perception data corresponding to the request type and request parameters, i.e., the target perception data corresponding to the data request instruction. The target perception data is then encapsulated to obtain the target response data.

[0071] In some embodiments, the transmission module specifically includes:

[0072] The encryption unit is configured to receive target response data sent by the data encapsulation module, encrypt the target response data to obtain encrypted response data, and send the encrypted response data to the transmission unit.

[0073] The transmission unit is configured to receive encrypted response data sent by the encryption unit and transmit the encrypted response data to the Internet of Things platform 103.

[0074] Specifically, when transmitting target-format sensing data to the Internet of Things (IoT) platform 103, the IoT platform 103 can encrypt the target-format sensing data to obtain encrypted sensing data, and then send the encrypted sensing data to the transmission unit. The transmission unit then sends the encrypted sensing data to the IoT platform 103.

[0075] In this embodiment, the encryption algorithm used for encryption processing can be either a symmetric or asymmetric. In a symmetric encryption algorithm, only one key is used, and both the sender and receiver use this key to encrypt and decrypt the data. Asymmetric encryption algorithms, also known as public-key encryption algorithms, require two keys: a public key and a private key. In this embodiment, the encryption algorithm used for encryption processing is not limited.

[0076] Accordingly, after receiving the encrypted sensing data, the IoT platform 103 needs to verify and decrypt the encrypted sensing data to obtain the sensing data in the target format. It is understood that the decryption algorithm corresponds to the encryption algorithm. Through the above encryption and decryption processes, the security and integrity of data transmitted between IoT platforms 103 are ensured.

[0077] In some embodiments, the IoT sensing terminal 101 specifically includes:

[0078] The data transmission module is configured to acquire initial positioning data and send the initial positioning data to the real-time dynamic differential broadcasting platform 102.

[0079] The real-time dynamic differential broadcasting platform 102 specifically includes:

[0080] The differential data determination module is configured to receive the initial positioning data sent by the data sending module, perform differential processing on the initial positioning data to obtain target differential data, and send the target differential data to the IoT sensing terminal 101.

[0081] The IoT sensing terminal 101 specifically also includes:

[0082] The location determination module is configured to receive the target differential data sent by the differential data determination module, and determine the target location based on the target differential data.

[0083] Specifically, the data transmission module in the IoT sensing terminal 101 acquires initial positioning data and sends the initial positioning data to the real-time dynamic differential broadcasting platform 102. The initial positioning data consists of relevant parameters configured in the software, including server address, port number, differential data stream name, username, and password.

[0084] The IoT sensing terminal 101 connects to the server of the real-time dynamic differential broadcast platform 102 via the network based on the initial positioning data, following the NTRIP protocol. The IoT sensing terminal 101 then establishes a connection with the RTK server by inputting relevant information from the RTK server through its RTT software or application.

[0085] The differential data determination module of the real-time dynamic differential broadcasting platform 102 receives the initial positioning data sent by the data sending module, performs differential processing on the initial positioning data to obtain target differential data, and sends the target differential data to the IoT sensing terminal 101.

[0086] The location determination module of the IoT sensing terminal 101 receives target differential data from the real-time dynamic differential broadcasting platform 102. The target differential data includes information such as satellite orbit parameters and clock corrections to improve positioning accuracy.

[0087] The IoT sensing terminal 101 uses differential data receiving software to process the received target differential data and generate high-precision positioning results. The processing specifically includes the application of differential corrections and coordinate transformation.

[0088] For ease of description, the above apparatus is described in terms of its functions, divided into various modules. Of course, in implementing this disclosure, the functions of each module can be implemented in one or more software and / or hardware.

[0089] Based on the above description, this embodiment proposes a data transmission method, applied to the data transmission system provided in the above embodiment, such as... Figure 3 As shown, the method includes:

[0090] Step 201: The IoT sensing terminal acquires sensing data and sends the sensing data to the real-time dynamic differential broadcasting platform.

[0091] In practice, the system acquires sensing data and sends it to the real-time dynamic differential broadcasting platform. The sensing data is IoT sensing data, which typically includes real-time data from various sensors. For example, the sensing data may include temperature, humidity, pressure, or light intensity.

[0092] After processing and packaging the sensing data, the IoT sensing terminal transmits it to the real-time dynamic differential broadcasting platform via the NTRIP protocol. The NTRIP protocol was originally designed for GNSS differential data transmission, but its TCP / IP-based communication mechanism and flexible data processing capabilities make it suitable for transmitting IoT sensing data.

[0093] Step 202: The real-time dynamic differential broadcasting platform receives and stores the sensing data sent by the IoT sensing terminal.

[0094] In practice, after receiving the sensing data sent by the IoT sensing terminal, the real-time dynamic differential broadcasting platform stores the sensing data in the database.

[0095] Step 203: The IoT platform sends a data request instruction, so that the real-time dynamic differential broadcasting platform can receive the data request instruction and send the sensing data.

[0096] In practice, when generating a data request instruction, the IoT platform sends the data request instruction to the real-time dynamic differential broadcasting platform through the connected client or adapter in accordance with the interface specification. The data request instruction includes authentication information, request parameters, and request type.

[0097] The IoT platform sends a data request instruction, which the real-time dynamic differential broadcasting platform receives and then sends the sensed data.

[0098] Step 204: In response to receiving the data request instruction sent by the IoT platform, the real-time dynamic differential broadcasting platform transmits the target sensing data corresponding to the data request instruction to the IoT platform.

[0099] In practice, when the real-time dynamic differential broadcasting platform receives a data request instruction from the IoT platform, it indicates that the IoT platform needs to obtain the sensing data of the IoT sensing terminal and transmit the target sensing data corresponding to the data request instruction to the IoT platform.

[0100] Step 205: The IoT platform receives the target perception data sent by the real-time dynamic differential broadcasting platform, so that the IoT platform can monitor the target perception data.

[0101] In practice, the IoT platform receives the target perception data sent by the real-time dynamic differential broadcasting platform, and realizes functions such as intelligent identification, positioning, tracking, and monitoring of the target perception data.

[0102] The above solutions reduce the difficulty of embedded software development for IoT sensing terminals, lower hardware platform resource requirements, shorten the R&D cycle of terminal devices, improve device stability, and facilitate the installation and maintenance of terminal devices. They also promote the application of BeiDou and IoT technologies in fields such as roads, agriculture, and power, and facilitate the application and promotion of real-time dynamic differential broadcasting platforms and IoT platforms.

[0122] For example, upon receiving a user's active request, a prompt message is sent to the user to explicitly inform them that the requested operation will require the acquisition and use of the user's personal information. This allows the user to independently choose, based on the prompt message, whether to provide personal information to the software or hardware such as electronic devices, applications, servers, or storage media performing the operations of this disclosed technical solution.

[0123] As an optional but not limited implementation, in response to a user's active request, sending a prompt message to the user can be done via a pop-up window, where the prompt message can be presented in text format. Furthermore, the pop-up window can also include a selection control allowing the user to choose "agree" or "disagree" to provide personal information to the electronic device.

[0124] It is understood that the above notification and user authorization process are merely illustrative and do not constitute a limitation on the implementation of this disclosure. Other methods that comply with relevant laws and regulations may also be applied to the implementation of this disclosure.
