[0028] The embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application.

[0029] Reference Figure 1 The present application provides a parameter-configurable telemetry terminal device, which is based on an adaptive program architecture 120 and communicates with a host computer 110 through a lightweight protocol, including: The storage module 11 is used to store the configuration parameters obtained from the host computer and output the configuration parameters to the control module when powered on or queried; The control module 12 is used to receive configuration parameters, convert the data into a data stream format defined by the protocol for transmission to the host computer, and use the data interaction function to transfer data between the functional submodules of the control module for hardware control; The interface expansion module 13 includes a variety of different hardware interfaces, which are used to call the corresponding hardware interface according to the functional functions of each functional submodule, and perform data query or data reading operations according to configuration parameters.

[0030] Specifically, refer to Figure 2 The configurable telemetry terminal device in the embodiment of the present application is based on the adaptive program architecture, communicates with the host computer through a customized lightweight protocol, and stores the configuration parameters in the memory, i.e., the storage module after receiving them; when powered on or queried, the memory outputs the configuration parameters to the control module. After receiving valid configuration parameters, when in the query state, the ARM (PS) end of the control module converts the data into the data stream format defined by the protocol and transmits it to the host computer; when in the power-on configuration state, the ARM (PS) end of the control module transmits the data to the parameter allocation function of the FPGA (PL) end through the data interaction function, and then transmits it to each function, respectively controlling different hardware interface modules, and querying or reading data according to the configuration parameters.

[0031] Further, the control module includes a PS port and a PL port; The PS port executes the ARM function, which is used to convert the data into the data stream format defined by the protocol and transmit it to the host computer when in the query state, and transmit the data to the parameter allocation function of the PL port through the data interaction function when in the power-on state; The PL port executes the FPGA function, is used to receive the data sent by the PS port through the data interaction function, and transmit the data to the parameter allocation function, and transmit the data to the function function of each functional submodule through the parameter allocation function, so as to control different hardware interface modules according to the function function, and query or read data according to the configuration parameters; The functional functions include an analog quantity analysis function, a digital quantity monitoring function, a video transmission analysis function, a serial port communication function and a frame encoding function.

[0032] Specifically, the PS port (processor system port) is responsible for executing the ARM (Advanced RISC Machine) function, which is mainly used to process status queries. During the query process, the acquired data is converted into a data stream format that conforms to the protocol definition and transmitted to the host computer.

[0033] In the power-on state, data is sent to the parameter assignment function of the PL (programmable logic device) port through the data interaction function.

[0034] Through the data conversion algorithm, the original data format is parsed into a standardized data stream format to ensure integrity and accuracy in data transmission. Combined with the data interaction function, the PS port can effectively communicate with the PL port to ensure that data is quickly and accurately distributed to the corresponding functional sub-modules.

[0035] The PL port (Programmable Logic Device Port) executes the FPGA function and receives the data sent from the PS port through the data interaction function. The received data is forwarded to the parameter allocation function so that the data can be further allocated to the function functions of each functional submodule according to the received configuration parameters and functional requirements.

[0036] The PL port perfectly implements the data receiving and forwarding mechanism, ensuring the efficient flow of data between different modules. The parameter allocation function effectively passes the data to each module, ready to receive and process the data.

[0037] These functions are responsible for processing and controlling specific hardware interface modules, including: Analog analysis function: Processes and analyzes analog signals and converts them into digital data that can be understood by the system. It is suitable for applications such as ADC in actual application scenarios.

[0038] Digital quantity monitoring function: monitors digital signals in real time to ensure that the system can effectively control digital input signals. It is applicable to the Digital Input module.

[0039] Video transmission and parsing function: processes video data streams, performs decoding and parsing, and ensures that video information can be correctly transmitted and processed in the system. It is suitable for cameras or video acquisition devices.

[0040] Serial port communication function: realize serial port communication with external devices, and can achieve reliable data exchange with other terminals or computers.

[0041] Frame coding function: performs frame coding on data to ensure the efficiency and security of data transmission, which is suitable for data transmission applications with high requirements.

[0042] Furthermore, the interface expansion module is coupled with the core circuit through the inter-board connector and is responsible for the expansion of other non-high-speed signal interfaces. Five LTM2881 chips can be mounted as 485 / 422 communication capabilities for regional navigation and other 485 / 422 device inter-board communication; the MAX9218 chip is used for video data analysis and transmission; and the SN74VC4245 chip is reserved for external digital quantity monitoring or control.

[0043] The working process of the telemetry terminal device in the embodiment of the present application is specifically as follows: When the host computer needs to query the status, the PS port converts the query request into the data stream format defined by the protocol and sends it to the host computer. In the power-on state, the PS port transmits the necessary data to the parameter allocation function of the PL port through the data interaction function. After receiving the data, the PL port passes it to the parameter allocation function, which then forwards the data to various function functions. Each function controls the corresponding hardware interface module according to the requirements of the configuration parameters to perform query or read data operations.

[0044] Optionally, the PS port is specifically used for: Parse the communication data stream to obtain configuration information, write the configuration information into a dedicated Flash memory through the SPI protocol, and send it to the PL port when the computer is started; The original parameters are backed up during the communication process. When the host computer confirms that the communication is correct, the parameter backup thread is destroyed.

[0045] Specifically, in the data communication process between the host computer and the telemetry terminal device in this embodiment, the configuration information is firstly obtained by parsing the received data stream. The parsing process extracts key information in the format defined by the protocol.

[0046] The acquired configuration information is written into a dedicated Flash memory through the SPI protocol. After parsing, the control module packages the configuration information into an SPI transmission format and transmits it to the Flash memory through the SPI interface. When the telemetry terminal is powered on, the system reads the stored configuration information from the Flash memory. After reading, the configuration information is sent to each functional submodule through the PL (programmable logic device) port to reload and apply parameters.

[0047] Furthermore, during the communication process, the current parameters are backed up. By creating a separate thread or process, the parameters are stored in a temporary area to ensure that the previous configuration state can be restored at any time. Once the host computer confirms that the communication with the telemetry terminal is correct and the received configuration is running normally, a confirmation command will be issued. After receiving the confirmation command, the parameter backup thread will be safely destroyed and the relevant resources will be released.

[0048] The embodiment of the present application obtains configuration information by parsing the communication data stream and stores it in the Flash memory through a reliable SPI protocol so that it can be loaded and applied at startup. By backing up the original parameters and destroying the backup thread after confirmation, a standard mechanism is provided to ensure the security of communication and the integrity of parameters.

[0049] Optionally, the PS port is further used for: Parse the CAN bus command and send it to the state configuration function of the PL port synchronously through the AXI protocol using the data interaction function to process the data; Read the parameter information of the memory at each power-on, and send the parameter information to the PL port through the power-on configuration function to update the configuration information; The PL port is also used for: Receive parameter information sent by the PS port through a power-on configuration function, and update configuration information based on the parameter information.

[0050] Specifically, refer to Figure 3 In this embodiment, the PS side also needs to parse the CAN bus command, and use the AXI protocol to synchronously send the data to the state configuration function of the PL side using the data interaction function to process the data reasonably. At the same time, the general software architecture requires that after each power-on, the parameter information in the memory is read, and then the power-on configuration function is used to send the updated configuration information to the FPGA.

[0051] The telemetry system achieves efficient configuration management by parsing CAN bus commands, reading and updating parameters. The AXI protocol is used to synchronously send instructions to the FPGA port, so that data processing has fast response capabilities. When powered on, the system reads the parameter information in the memory to ensure that the configuration information is updated immediately. The PL port receives data from the PS port and the power-on configuration function, further optimizing the system configuration and flexibility. Reference Figure 4 The interface expansion module includes but is not limited to a digital quantity monitoring circuit, a video transmission analysis circuit, and a serial communication circuit.

[0052] Reference Figure 5 The present application also provides a lightweight communication method based on a telemetry terminal. The telemetry terminal device is based on an adaptive program architecture and communicates with a host computer through a lightweight protocol, including: S501. Receive configuration parameters through the control module, convert the data into a data stream format defined by the protocol for transmission to the host computer, and use the data interaction function to transfer data between the functional submodules of the control module for hardware control; S502. Call the corresponding hardware interface according to the functional functions of each functional sub-module through the interface expansion module, and perform data query or data reading operations according to the configuration parameters.

[0053] Optionally, the data is converted into a data stream format defined by the protocol for transmission to a host computer, and the data interaction function is used to transfer data between the functional submodules of the control module for hardware control, including: When querying the status, the data is converted into the data stream format defined by the protocol through the PS port and transmitted to the host computer; In the power-on state, data is transferred to the parameter assignment function of the PL port through the data interaction function via the PS port; The data sent by the PS port through the data interaction function is received through the PL port, and the data is transmitted to the parameter allocation function, and the data is transmitted to the function function of each functional sub-module through the parameter allocation function, so as to control different hardware interface modules according to the function function and query or read data according to the configuration parameters.

[0054] Optionally, the process of the adaptive program architecture communicating with the host computer through the lightweight protocol is specifically as follows: Receive the write data request from the host computer, complete the first set of handshakes, and send a response to the host computer; Receive the start data writing instruction sent by the host computer and respond with the current status to complete the second set of handshakes; After the status of the host computer allows, the data writing process is started to start data writing; each block of data is sent in a cycle of up to 255 frames until the end; After receiving the block end frame, the check result is calculated and sent to the host computer as a check of the integrity of the written data; After the host computer passes the inspection, it determines that the information transmission is completed successfully and generates a write end instruction; The secondary verification result is recalculated based on the write end instruction and sent to the upper computer so that the upper computer can make an abnormal judgment on the secondary result. If the upper computer judges it to be abnormal, the read instruction is executed to check the configuration information.

[0055] Specifically, the detailed process of this application is as follows: First, a write data request is received from the host computer. The request may include the start identifier of the data block, the data length, and related parameters. After completing the first set of handshakes, a response signal is sent to the host computer to confirm that the write data request has been successfully received.

[0056] Secondly, the telemetry system receives the start data writing instruction sent by the host computer, which indicates that the telemetry system is ready to start the actual data writing process. According to the current system status, the telemetry system returns the status with a response signal to complete the second set of handshakes.

[0057] After the host computer confirms that the current state allows it, the telemetry system starts the data writing process. Each block of data is sent in a loop with a maximum of 255 frames, and the process continues until all data blocks are successfully transmitted. It should be noted that in order to meet the maximum limit of 255 frames, the system needs to split and encapsulate the data blocks to be sent to ensure that the data is complete and complies with the communication protocol.

[0058] After all data transmission is completed, the telemetry system will receive a specific block end frame, indicating that the data transmission has ended. The telemetry system performs an integrity check on the transmitted data and generates a check result. The calculated check result is sent back to the host computer for it to verify the integrity of the data transmission.

[0059] After receiving the verification result, the host computer verifies it. If the verification passes, the system determines that the information transmission is successfully completed and generates a write end instruction. After receiving the write end instruction, the telemetry system recalculates the verification result and sends the calculation result to the host computer.

[0060] The host computer makes an abnormal judgment on the secondary verification result: if the judgment is wrong, the system will execute the read instruction to check the configuration information to ensure that the system runs in the expected state, thereby ensuring the accuracy of the data and the stability of the system.

[0061] Reference Figure 6 , Figure 6This is a flow chart of the lightweight communication protocol in this application, in which the execution process of the write instruction is as follows. The host computer initiates a write data request, and after the telemetry terminal receives it, it completes the first set of handshakes; after receiving the response, the host computer issues a start write data instruction, and after receiving it, the telemetry terminal responds with the current status and completes the second set of handshakes; after the host computer determines that the terminal status allows, it can start writing data, with a maximum of 255 frames per block of data, which are sent in a loop until the end; after receiving the block end frame, the terminal device calculates the CRC32 check result and sends it to the host computer. After the host computer passes the inspection, it considers that the information has been successfully sent, and issues a write end instruction. The terminal device calculates and sends the check result again; if the host computer judges that the check result is correct, no response is required. If it is judged to be abnormal, the read instruction is executed to check the configuration information. The same applies to the read instruction.

[0062] Optionally, receiving parameter configuration instructions sent by a host computer; Perform CRC32 check based on configuration parameters. If both check results are correct, read the configuration parameters and compare them. If any verification result or parameter comparison result is wrong, re-receive the parameter configuration command sent by the host computer; Determine whether the parameter configuration command has been issued more than five times; When the parameter configuration instruction is repeated more than five times, a reset signal is sent to determine that the telemetry terminal is abnormal, notify the host computer to restore the original configuration parameters, and issue an error warning.

[0063] In this embodiment, the lightweight communication mode performs error correction by means of CRC check and instruction reading. During the communication process, if the CRC check is abnormal, the telemetry terminal device storage information needs to be read. If the data transmission is judged to be wrong for multiple times, the host computer interface will remind the error and reset the configuration parameters of the telemetry terminal device; after the data is written normally, the telemetry terminal device storage information still needs to be read and compared with the sent parameters. If the data is inconsistent, the configuration parameters of the telemetry terminal device still need to be reset.

[0064] Specifically, in each communication, the telemetry terminal device uses CRC (Cyclic Redundancy Check) to check data integrity. The data sent includes commands and data blocks, and each data block is calculated and attached with a CRC check code before sending.

[0065] When the host computer receives the data, it first performs a CRC check to confirm the correctness of the check code. If the CRC check is incorrect, the host computer will perform the following steps: Read the storage information of the telemetry terminal device.

[0066] Determine whether the data transmission error is caused by a communication error.

[0067] If it is determined that the transmission is erroneous, an error reminder is issued and the configuration parameters of the telemetry terminal device are reset.

[0068] Verification after normal data writing: After successfully completing the data writing, it is still necessary to read the storage information of the telemetry terminal device.

[0069] The read data is compared with the sent parameters. If the data are inconsistent, the configuration parameters of the telemetry terminal device are reset.

[0070] Reference Figure 7 , the parameter calibration and exception handling process of this application is as follows: Calculate and verify the CRC of the sent data to ensure that the data has not been tampered with or lost during transmission. Check whether the sent parameters are consistent with the received data.

[0071] If any calibration anomaly occurs, the telemetry system will perform the following steps: Re-issue the parameter configuration command.

[0072] To ensure system stability, perform necessary retries.

[0073] If calibration anomalies occur five times in succession, the system will determine that the telemetry terminal device is abnormal and perform the following emergency processing: The host computer will restore the original configuration parameters to the telemetry terminal.

[0074] Send error warnings to alert operators and record error status.

[0075] In summary, the correction process of the embodiment of the present application is as follows: If the CRC check fails, read the device storage information and check whether it is caused by a transmission error.

[0076] If the data is consistent, continue. If the data is inconsistent, reset the configuration parameters.

[0077] After successful writing, the stored information is read and compared with the sent data. If any inconsistency is found, the configuration parameters are reset.

[0078] For each parameter transmission and CRC calibration, if any calibration is abnormal, the configuration command will be re-issued. If there are five consecutive calibration abnormalities, an alarm will be issued, the original configuration will be restored, and corresponding records will be made.

[0079] For equipment abnormalities, take corresponding measures to ensure stable operation of the system, and track and record them for subsequent problem troubleshooting.
