The card reader is a special card reader customized and formed for a user, and development is not needed. The processor is a processing core part of the downloading terminal and is responsible for automatic identification of the insertion or extraction of the data card, and the identification information is sent to the flight parameter computer for indication through the optical fiber exchanger and the optical fiber special path. After the flight parameter computer recognizes that the remote data card is inserted, the flight parameter downloading software waits for an operation command of a user. If the operator executes the data downloading operation on the flight parameter downloading software, the processor receives an operation command of downloading data from the flight parameter computer, and downloads and transmits partial or all contents of the data card. The processor also loads and converts the USB3.0 protocol or the 1394A/B protocol into the TCPIP protocol, and converts the data packet read from the USB3.0 or the 1394 interface into the TCPIP data packet, and transmits the TCPIP data packet to the hard disk of the flight-parameter computer for storage through the special optical fiber line. The PLC is industrial high-reliability control equipment, automatically monitors the working state of the whole downloading terminal, receives control of the flight parameter computer monitoring APP software through an optical fiber dedicated line, and feeds back the running state of the downloading terminal to the flight parameter computer monitoring APP software in time. The optical fiber switch is optical signal interface and electric signal network interface conversion equipment, and mainly plays a role in bridging signals in the downloading terminal. The power module provides power for each part of the downloading terminal, the input of the power module is 220V alternating current, the output of the power module is direct current, and the power module is respectively supplied to the processor, the card reader, the PLC and the optical fiber switch.
After the download terminal is powered on, firstly initializing a hardware platform, including initializing each communication interface, after the initialization is completed, the terminal performs starting-up self-checking, and the self-checking items include the working state, the memory state, the CPU state, the card reader state and the like of each interface. If the self-check finds an abnormality, the PLC controller resets the processor, restarts the processor, repeats the previous initialization and self-check operation, and if the abnormality is detected again, the PLC controller tries to power off the processor, and after the power off of the processor is stopped for 5 seconds, the PLC controller is powered on again, and repeats the previous initialization and self-check operation again. If the power-off operation cannot be restored to the normal state, the panel indicator lamp is used for carrying out fault flashing warning. If the self-check is normal, the processor enters a normal working state and is in a monitoring card reader state, if the insertion of the data card is monitored in the state, the processor transmits the identified card information to the flight-reference computer through the special optical fiber line, and a local equipment manager of the flight-reference computer automatically identifies the insertion of the USB or 1394 equipment, as if the same equipment is locally inserted. After the identified card information is transmitted to the flight parameter computer by the downloading terminal, the flight parameter computer is always in an operation command state waiting for the flight parameter computer, if the flight parameter computer issues a data downloading command at the moment, the processor performs data downloading operation according to the received operation command and parameters, meanwhile, the downloaded flight parameter or audio/video data is automatically converted into a TCPIP data packet to be transmitted to the flight parameter computer through a special optical fiber channel, and the flight parameter computer receives the data packet and writes the data packet to a specified hard disk position. When the operation is finished, the user pulls out the data card, the processor also informs the flight parameter computer of the data card pulling-out information, and after the flight parameter computer receives the card pulling-out information, the flight parameter computer pops out the card pulling-out information and exits the monitoring APP. When the flight parameter computer detected by the processor exits the monitoring APP and the card is pulled out, the flight parameter computer is set to be in a dormant state, and if the user has a data card inserted into the card reader at the moment, the processor is automatically awakened to be restarted. The PLC in the downloading terminal can consistently monitor the health state of the whole downloading terminal, once abnormality is found, the local recovery test can be tried, the processor is diagnosed first, reset operation is carried out, if the operation cannot be recovered to be normal for a plurality of times, the local panel indicator lamp can be used for warning, and meanwhile, if the flight computer is connected with the downloading terminal, the abnormality information can be informed to the flight computer for monitoring APP for processing.
The working mode of the whole transmission system in the invention is as follows: the flight parameter computer is arranged in a flight parameter room of the tower, and has the main functions of running a monitoring APP and flight parameter downloading software, remotely controlling a downloading terminal, receiving and storing flight parameter and audio and video data. When the flight parameters and audio and video data are required to be downloaded, the monitoring APP software of the desktop is started first, after the monitoring APP software is started, the working state of the on-site downloading terminal of the apron shelter, the state of whether the data card is inserted or not and the like are automatically obtained, if the downloading terminal is found to work abnormally, the monitoring APP can automatically or manually reset and restart the downloading terminal according to user configuration so as to enable the downloading terminal to recover to the normal state, and if the repeated resetting and restarting operations cannot be recovered to the normal state, the APP can pop up a red warning and inform an error code. If the working state of the downloading terminal is normal and the insertion state of the flight parameter or audio/video data card is detected, the user can click a 'enter software' button on the monitoring APP, one key enters a flight parameter data downloading software operation interface, and the flight parameter data downloading software is the software used by the original user, so that the use habit of the user is reserved, and the new software is not required to be learned and trained. The user operates the flight parameter data downloading software, configures related parameters, selects the content to be downloaded, clicks the downloading operation, and then the flight parameter data downloading software automatically sends a command to the downloading terminal of the apron side cabin through the optical fiber private line, and the downloading terminal executes the downloading command. And after receiving the operation command of the flight parameter data downloading software, the downloading terminal processes the flight parameter data completely according to the operation command, wherein the processing comprises reading of data card data, conversion from USB to TCPIP, conversion of data packet format and transmission of flight parameter data to the flight parameter computer. In the transmission process of the flight parameter or audio/video data from the downloading terminal to the flight parameter computer, the monitoring APP can always monitor the working state of the downloading terminal and the data transmission state, and once abnormality is found, an abnormality prompt is popped up to a user, and an explicit operation completion prompt is also generated when the data transmission is completed. After the user performs the required operation, the fly parameter data downloading software is closed first, and then the monitoring APP is exited.
