Abstract

The utility model belongs to airborne electronic equipment in aviation, and relates to a wireless caching recorder. The wireless caching recorder is connected with an information source through a bus and a data processor arranged at the front end of the bus to receive flying data information from a flying data acquisition unit, a CPU connected with the other end of the bus records the received flying data information into a general data storage medium through a USB interface, and when a collected aircraft switching signal meets the sending requirement, the wireless caching recorder can be in seamless connection with a flying data processing center through a four-path GSM (Global System for Mobile Communications)/GPRS (General Packet Radio Service) module connected with the CPU, so as to efficiently and reliably send the data to the flying data processing center.

Description

The wireless register of getting soon

Technical field

The utility model belongs to the airborne electronic equipment, relates to a kind of wireless register of getting soon.

Background technology

Air environment is got register (Quick Access Recorder soon, be called for short QAR) can write down more flight information and have long writing time, and can carry out fast data and download, therefore obtain being extensive use of of all kinds aircraft always.But, traditional register of getting soon needs to take out data card after each flight, flight safety administrative authority could sense data with card reader then, data card may need to be allowed to deposit a very long time by factor according to one's analysis, when being stuck in the recording capacity that reaches regulation, partial data need just can be continued on for flight behind the reformatting, this data are recovered and the process of playback can expend a large amount of man power and materials, also may cause the loss of vital data on the data card, these situations have all had a strong impact on the normal use of user to QAR.

Summary of the invention

The technical matters that solves:

The process that the tradition air environment is got recorder data recovery and playback soon can expend a large amount of man power and materials, also may cause the loss of vital data on the data card, and these situations have all had a strong impact on the normal use of user to QAR.The utility model is got the deficiency that register expends a large amount of man power and materials soon at general, and a kind of efficient, multi-functional, rapid and low airborne equipment of safeguarding cost is provided.

Technical scheme:

This wireless register of getting soon comprises bus and front end data processor, central processing unit, USB interface, conventional data storage medium, hyperchannel RS-422 transceiver and wireless transport module.Bus links to each other with the extrinsic information source, and the front end data processor of bus links to each other with central processing unit, and central processing unit links to each other with the conventional data storage medium by USB interface, and central processing unit is connected with wireless transport module by hyperchannel RS-422 transceiver simultaneously.Thereby record is from the flying quality information of flying quality collecting unit; A plurality of switching signals such as wheel load signal that also can be by gathering aircraft, cargo door opening, passenger cabin door opening judge whether to start radio transmission, when satisfying data download condition, the wireless register unlatching antenna of getting soon enters emission state, adopt GSM/GPRS communication modes and floor treatment station to carry out seamless link, transfer data to the flying quality processing enter; Can also when operate as normal, provide the duty indication by the state delivery outlet by central processing unit, provide fault warning when breaking down.

Beneficial effect:

Wirelessly get register soon (Wireless Quick Access Recorder is called for short: WQAR) overcome the deficiency of traditional Q AR, become more fast and reliable.It obtains other any data that may wish with users such as the abundant flying quality of recorded content and Air Diary, maintenance records automatically by bus in the course of the work.The flying quality of flight course is compressed and encrypts the back by the seamless land station that is transferred in wireless base station and internet, after handling and analyze by central station then, just can finish playback, analysis and the report of flying quality fast, can effectively reduce the link and the time of data distribution.WQAR can be at the central station of teletransmission flying quality after the aircraft landing to aviation administrative authority, this offers the long-range means of obtaining crucial flying quality fast of data analysis center, make flying quality and information management department form one direct " point-to-point " relation, help initiatively to improve flight quality evaluation, minimizing maintenance time and the cost of aircraft.

Embodiment

The utility model can adopt the two-phase Harvard sign indicating number bus that meets ARINC 573/717 standard and Harvard's sign indicating number driver, ARINC429 bus and the FPGA that is attached thereto that is attached thereto and 10/100Mbps industry ethernet and isolating transformer that is attached thereto and ethernet transceiver, receives and write down the flying quality information from the flying quality collecting unit; By supporting the USB interface of high speed, full speed and low-speed mode, the data that receive are write USB flash disk.

Central processing unit of the present utility model is selected the embedded MPC8280 processor of PowerPC series high-performance for use.Ethernet interface is formed the ethernet communication interface unit jointly by two-way 10/100Mbps Ethernet control interface, protocol chip and isolating transformer that PowerPC 8280 carries, wherein one the tunnel is used for carrying out data communication with collecting unit, and one the tunnel is used for system maintenance; Power circuit general+28VDC direct supply changes into the required operating voltage of each device, and power down indication, overcurrent protection, overvoltage protection and power down protection are provided; FPGA is transferred to central processing unit with data by whole frame structure after by chip for driving the Harvard's coded signal that receives being resolved, can be to Harvard's sign indicating number transfer rate automatic identification and the self-adaptation of (64,128,256,512,1024,2048 word/second); By utilize USB controller and the external transceiver that PowerPC 8280 carries constitute at a high speed, at full speed and the USB host interface of low-speed mode USB flash disk is carried out read-write operation; In wireless communication state, PowerPC 8280 transfers data to the wireless transmit that the GSM/GPRS module is carried out data by four road serial line interfaces, and the GSM/GPRS module adopts four-way to transmit simultaneously.The wireless wireless transmission method of getting register is soon selected: consider safe reliability, technology maturity, implement economy and user airport facility condition, large-scale 3G network construction need expend huge fund, the 3G technology standard version is constantly evolution still, and operator is owing to worry to go wrong at aspects such as roaming and compatibility with later new standard, each big operator still carries out the Reasonable Scale of networking with prior art in comprehensive assessment, causing can be all very limited for the 3G terminal equipment that the user selects on 3G network coverage and the market, also only has China and American-European countries to have 3G network at present.Therefore, the 3G communication system should not be used for the wireless register of getting soon in a short time.Because the 3G core net is still based on the GSM/GPRS network, wireless transmission method therefore of the present utility model adopts the GSM/GPRS mode, and can compatible 3G by software upgrading.

PowerPC 8280 processors carry out software design based on VxWorks 6.7 real-time embedded operating systems.The plate level support package (BSP) of VxWorks 6.7 real-time embedded operating systems is finished the software-driven to interfaces such as ethernet controller, USB HOST controller and RS232/RS422/RS485; Application layer software is finished the data that each communication interface is received and is carried out encryption, compression and the segmentation organization work of data, gives flying quality processing enter with the standard radio communications protocol by GSM/GPRS base station network system transmissions with data by wireless module; Software on ground operating system is finished acceptance, processing and the playback of data.
