Description

Technical Field

[0001] The present invention relates to the technical field of transmission, and specifically to a transmission analysis system based on intelligent management. Background Art

[0002] With the development of the aircraft system, the types and quantities of its single-machine equipment are increasing day by day, and the amount of data generated during the test also shows an explosive growth trend. The main control chips and low-speed data interfaces used in traditional ground measurement and control systems can no longer meet the requirements. The noise and impact generated during flight tests pose great safety hazards to the staff. The last system test position before the flight test needs to maintain a certain safety distance from the flight test site. Therefore, the ground measurement and control system needs to perform long-distance data interaction with the aircraft. The extension of the data transmission path poses a test to the reliability of the transmission. Moreover, at present, the ground measurement and control system realizes data interaction between the central processor and different external single-board devices through control buses such as PCI and PXI, which is widely used in aerospace measurement and control systems. However, the ground measurement and control system constructed by these two bus technologies has a large and complex external structure, which is not conducive to operation in the limited space of the test position, and has high manufacturing and transportation costs. Therefore, it is necessary to design a transmission analysis system based on intelligent management with strong stability and high transmission efficiency. Summary of the Invention

[0003] The purpose of the present invention is to provide a transmission analysis system based on intelligent management to solve the problems raised in the above background art.

[0004] To solve the above technical problems, the present invention provides the following technical solutions: A transmission analysis method based on intelligent management includes: Conducting instruction sending and status receiving management of the data transmission system; Controlling the data transmission of the data transmission system; Conducting management optimization analysis of the data transmission system; Conducting data acquisition and storage processing of the data transmission system; The conducting of instruction sending and status receiving management of the data transmission system includes: Enabling the data transmission system to communicate with the telemetry device through the RS-422 interface, controlling the host computer to send telemetry device instructions 422-1 instruction, 422-2 instruction (mutually backup) and editing and control controller and measurement and control console instructions to the PS side through the TCP protocol. After the PS side identifies the instruction type, it writes them into different address spaces in the BRAMO. The PS writes the instructions into the BRAMO and sends corresponding interrupt signals to the ctr_UART; Online detection is performed on the electrical interface signal and the optical interface signal to select the status data reception interface, either the electrical interface status or the optical interface status. Then, the status information of this interface is received using the UART protocol and written into BRAM1 through the status buffer data bus. Two address spaces, st0 and st1, are allocated in BRAM1. When the status data is written into st0, the PL sends an interrupt signal, Interface Status 0 Interrupt, to the PS, and the PS reads the data in st0. When the status data is written into st1, the PL sends an interrupt signal, Interface Status 1 Interrupt, to the PS, and the PS reads the data in st1. The two address spaces alternate between reading and writing to complete the upload and reception of the status data.

[0005] According to the above technical solution, the data transmission control of the data transmission system includes: After receiving the data request instruction sent by the MAC layer, the data cached in the FIFO is encapsulated in the format of a UDP data frame and sent to the MAC layer, and the enable signal is continuously sampled. When a rising edge of the enable signal is detected, the data transmission process is started.

[0006] According to the above technical solution, the management optimization analysis of the data transmission system includes: When the MAC input data valid flag is pulled high, data reception starts. First, the MAC frame header is received. If the protocol type is an ARP frame, the remaining data of the address recognition data frame is received. After the reception is completed, it is judged whether the frame valid flag is 1. If it is 1, the ARP response signal is enabled to output the source MAC and IP addresses in the address recognition data frame. If it is not 1, the frame data is discarded and the idle state is returned.

[0007] According to the above technical solution, the management optimization analysis of the data transmission system further includes: System data interaction is realized through the SRIO transmission protocol. The request and response transactions are encapsulated in the serial physical layer packet, 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 end receives the upper computer TCP network instructions through the instruction reception port, including telemetry device instructions (422-1 instruction, 422-2 instruction), editing and control controller instructions, and measurement and control console instructions. After the PS end receives the corresponding instructions, it sends a reply command to the upper computer through port number 6010 to confirm that the instruction is received correctly. At the same time, the instructions are distinguished through the instruction channel information word, and the 10-byte instructions are forwarded to the fixed address space of BRAMO at the PL end.

[0008] According to the above technical solution, the data acquisition and storage processing of the data transmission system includes: Collect the real-time operation data information of the data transmission system, organize it into a set form, and then transmit it to the background monitoring terminal for management personnel to view; Perform blockchain backup storage on the collected data information to provide an accurate reference basis for subsequent system failures.

Description of the Drawings

[0014] The drawings are used to provide a further understanding of the present invention, and constitute a part of the specification. They are used together with the embodiments of the present invention to explain the present invention, and do not constitute a limitation to the present invention. In the drawings: Figure 1 is a flowchart of a transmission analysis method based on intelligent management provided in Embodiment 1 of the present invention; Figure 2It is a block diagram of a transmission analysis system based on intelligent management provided by the second embodiment of the present invention. Detailed implementation manners

[0015] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0016] Embodiment 1: Figure 1 It is a flowchart of a transmission analysis method based on intelligent management provided by the first embodiment of the present invention. This embodiment can be applied to a data transmission system. This method can be executed by a transmission analysis system based on intelligent management provided by the embodiments of the present invention. The system consists of multiple software and hardware modules, such as Figure 1 As shown, the method specifically includes the following steps: S101. Manage the instruction sending and status receiving of the data transmission system; Exemplarily, in the embodiment of the present invention, the data transmission system communicates with the telemetry device through the RS-422 interface. The control host computer sends telemetry device instructions 422-1 instruction, 422-2 instruction (backup each other), and acquisition and editing controller and measurement and control station instructions to the PS side through the TCP protocol. After the PS side identifies the instruction type, it writes them into different address spaces in the BRAMO. The PS writes the instruction into the BRAMO and sends a corresponding interrupt signal to the ctr_UART. In this step, in order to prevent misoperation due to interference, the interrupt signal is processed in two beats. The ctr_UART receives the instruction interrupt signal, reads the data corresponding to the address in the BRAMO and stores it in the instruction register in different address spaces of the cmd_buffer. After the reading is completed, a rising edge of the pl2ps_cmd_done signal is generated and sent to the PS side. The PS confirms the completion of the instruction transmission according to the received rising edge signal and can perform the next instruction transmission. After the ctr_UART instruction reading is completed, an f_cmd_done flag is generated. When the rising edge of the f_cmnd_done flag is detected, the instruction data stored in the 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, and the low byte second. The data bit transmission order is low bit first.

[0017] Select the interface electrical interface state or optical interface state for online detection of electrical interface signals and optical interface signals to receive status data, then receive the status information of the interface via the UART protocol and write it into BRAM1 through the status buffer data bus. Two address spaces, st0 and st1, are allocated in BRAM1. When the status data is written to st0, the PL sends an interrupt signal, Interface Status 0 Interrupt, to the PS, and the PS reads the data in st0. When the status data is written to st1, the PL sends an interrupt signal, Interface Status 1 Interrupt, to the PS, and the PS reads the data in st1. The two address spaces are alternately read and written to complete the upload and reception of status data.

[0018] S102. Control the data transmission of the data transmission system; Exemplarily, in the embodiment of the present invention, after receiving the data request instruction sent by the MAC layer, the data cached in the FIFO is encapsulated in the format of a UDP data frame and sent to the MAC layer, and the enable signal is continuously sampled. When the rising edge of the enable signal is detected, the data transmission process is started. In this step, first, the first byte of the data request instruction received from the MAC layer is regarded as the start of this data transmission. Then, it is judged whether the MAC controller busy / idle flag bit ack 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 sending all the frame header information segments, for each data read from the FIFO, the data length counter cnt is incremented by 1. For each data read, it is judged whether cnt is equal to the corresponding data length. If the condition is met, it means that the data sending and packing are completed. When the correct data that meets the setting is not received after the data fetch request is sent at the measurement and control console, the data fetch request is resent to ensure the correct download and return to the idle state.

[0019] S103. Conduct management optimization analysis of the data transmission system; Exemplarily, in the embodiment of the present invention, when the MAC input data valid flag bit is pulled high, data reception starts. First, the MAC frame header is received. If the protocol type is an ARP frame, the remaining data of the address recognition data frame is received. After the reception is completed, it is judged whether the frame valid flag bit is 1. If it is 1, the ARP response signal is enabled to output the source MAC and IP addresses in the address recognition data frame. If it is not 1, the frame data is discarded and the idle state is returned. In this step, if the protocol type is an IP frame, the IP frame header and UDP frame header are received first, then the valid data is received and cached. After the reception is completed, it is judged whether the frame valid flag bit is 1. If it is 1, the data is output. Otherwise, it is judged that the frame data is invalid and the idle state is returned.

[0020] The system data interaction is realized through the SRIO transmission protocol. The request and response transactions are encapsulated in the serial physical layer packet, and the transaction types initiated by the target device are determined by the set fields Ftype and Ttype in the packet format. In this step, since the write transaction for writing data to the target device and the stream write transaction for large-volume DMA transmission, both of these transactions can write data to the address specified by the target party. Therefore, the data payload in the write transaction includes double words, words, half words, and bytes. The data payload of the stream write transaction packet is always a double word, supporting a maximum data volume of 256 bytes. And in the stream write transaction packet format, the three fields of Ttype, Rdsize / Wrsize, and srcTID are all defined as the ExtendedAddress field, which saves a large amount of data payload in the packet header for the stream write transaction type and has higher efficiency compared with the write transaction.

[0021] The PS side of the control system receives the TCP network instructions from the upper computer through the instruction receiving port, including telemetry device instructions (422-1 instruction, 422-2 instruction), acquisition and editing controller instructions, and measurement and control console instructions. After receiving the corresponding instructions, the PS side sends a reply command to the upper computer through port number 6010 to confirm that the instruction is received correctly. At the same time, the instructions are distinguished through the instruction channel information word, and the 10-byte instructions are forwarded to the fixed address space of BRAMO on the PL side.

[0022] S104. Perform data acquisition and storage processing of the data transmission system; Exemplarily, in the embodiment of the present invention, the real-time operation data information of the data transmission system is collected, sorted into a set table form, and then transmitted to the background monitoring end for management personnel to view; The collected data information is backed up and stored in the blockchain to provide an accurate reference basis for subsequent system failures.

After the PS end identifies the instruction type, it is written into different address spaces in BRAMO and sends a corresponding interrupt signal to ctr_UART; In this step, the interrupt signal is processed by two beats. When ctr_UART receives the instruction interrupt signal, it reads the data of the corresponding address in BRAMO and stores it in different address spaces in cmd_buffer in the instruction register.

The PS confirms that the instruction transmission is completed according to the rising edge of the received signal, and the next instruction transmission can be performed. After the ctr_UART instruction is read, the f_cmd_done flag is generated.

After all the frame header information segments are sent, each time a data is read from the FIFO, the data length counter cnt increases by 1. Each time a data is read, it is determined whether cnt is equal to the corresponding data length. If the condition is met, it means that the data transmission is packaged. If the control station does not receive the correct data that meets the setting after sending the data acquisition request, it will resend the data acquisition request to ensure that the data is correctly downloaded and returns to the idle state.
