Description

[0002] With the development of aircraft systems, the types and quantities of single machine devices are increasing day by day, and the amount of data generated in the test process also presents an explosive growth trend. The main control chip and low-speed data interface used by the traditional ground measurement and control system cannot meet the requirements. The noise and impact generated by flight test bring great safety hazards to the staff. The last system test site before flight test needs to maintain a certain safety distance from the flight test site, so the ground measurement and control system needs to interact with the aircraft at a long distance. The lengthening of the data transmission path tests the reliability of transmission, and the current ground measurement and control system realizes the data interaction between the central processor and different external single board devices through PCI, PXI and other control buses, which are widely used in space measurement and control systems. However, the ground measurement and control system constructed by using these two bus technologies has a large and complex structure, which is not conducive to operation in the limited space of the test site, and has high manufacturing and transportation costs.

Claims

1. A transmission analysis method based on intelligent management, characterized in that: include: Manage the sending and receiving of instructions for the data transmission system; Perform data transmission control on the data transmission system; Perform management optimization analysis of the data transmission system; To perform data acquisition, storage, and processing for the data transmission system; The management of instruction sending and status reception of the data transmission system includes: The data transmission system communicates with the telemetry equipment via an RS-422 interface. The host computer sends telemetry equipment instructions (first custom instruction, second custom instruction, and data acquisition controller and control console instructions) to the PS terminal via TCP protocol. The first custom instruction and the second custom instruction are backups of each other. After the PS terminal identifies the instruction type, it writes it into different address spaces in BRAMO and sends the corresponding interrupt signal to ctr_UART. In this step, the interrupt signal is processed in two steps. When the ctr_UART receives the instruction interrupt signal, it reads the data at the corresponding address in BRAMO and stores it in the different address space of cmd_buffer in the instruction register. After reading, it generates a rising edge of the pl2ps_cmd_done signal and sends it to the PS end. The PS confirms the completion of instruction transmission based on the rising edge of the received signal and can proceed with the next instruction transmission. After the ctr_UART instruction is read, it generates the f_cmd_done flag. When the rising edge of the f_cmd_done flag is detected, the instruction data registered in cmd_buffer in the instruction register is sent bit by bit through the instruction output interface according to the UART protocol. The data byte transmission order is high byte first, low byte last, and the data bit transmission order is low bit first. The system performs online detection of electrical and optical interface signals to select the interface for receiving status data, either the electrical interface status or the optical interface status. Then, it receives the status information of the interface using the UART protocol and writes it into BRAM1 via the status buffer data bus. Two address spaces, st0 and st1, are allocated in BRAM1. When status data is written to st0, PL sends an interrupt signal to PS, interrupting the interface status to 0, and PS reads the data from st0. When status data is written to st1, PL sends an interrupt signal to PS, interrupting the interface status to 1, and PS reads the data from st1. The two address spaces are alternately read and written to complete the uploading and receiving of status data. The data transmission control of the data transmission system includes: After receiving the data request instruction sent by the MAC layer, the data buffered in the FIFO is encapsulated in the format of a UDP data frame and sent to the MAC layer. The enable signal is continuously sampled. When a rising edge of the enable signal is detected, the data transmission process is started. In this step, the first byte of the data request instruction received from the MAC layer is taken as the beginning of this data transmission. Then, it is checked whether the busy / idle flag bit ack of the MAC controller is 0. If ack=0, it means that the MAC controller is currently occupied and returns to the idle state. If ack=1, the MAC frame header, IP frame header and UDP header are sent in sequence. After all frame header information segments are sent, the data length counter cnt is incremented by 1 for each data read from the FIFO. For each data read, it is checked whether cnt is equal to the corresponding data length. If the condition is met, it means that the data transmission is complete. If the correct data matching the settings is not received after the data retrieval request is sent by the control console, the data retrieval request is resent to ensure that the data is downloaded correctly and the idle state is returned. The management optimization analysis of the data transmission system includes: When the MAC input data valid flag is pulled high, data reception begins. First, the MAC frame header is received. If the protocol type is ARP frame, the remaining data of the address identification data frame is received. After receiving, it is determined whether the frame valid flag is 1. If it is 1, the ARP reply signal is enabled and the source MAC and IP address in the address identification data frame are output. If it is not 1, the frame data is discarded and the idle state is returned. System data interaction is achieved through the SRIO transmission protocol, which encapsulates request and response transactions in serial physical layer packets, and the transaction type initiated by the target device is determined by the set fields Ftype and Ttype in the packet format; The control system PS terminal receives TCP network commands from the host computer through the command receiving port, including: telemetry device commands, which include a first custom command and a second custom command that are backups of each other; data acquisition controller commands; and control console commands. After receiving the corresponding commands, the PS terminal sends a reply to the host computer through port number 6010 to confirm that the commands have been received correctly. At the same time, the commands are distinguished through the command channel information words, and the 10-byte command is forwarded to the PL terminal BRAMO fixed address space.

2. The transmission analysis method based on intelligent management according to claim 1, characterized in that: The data acquisition and storage processing of the data transmission system includes: The system collects real-time operational data from the data transmission system, organizes it into a predefined table format, and then transmits it to the backend monitoring terminal for administrators to review. The collected data will be backed up and stored on the blockchain to provide accurate reference for subsequent system failures.
