Fig. 2 is the utility model embodiment software flow schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is described in further details.
With reference to Fig. 1,2: it is the main frame power supply that receiver adopts the lithium battery that 14.4V and 4A maximum discharge current and capacity are 1700mAh, supply power mode was both directly powered by lithium battery, by straight charging circuit power supply, can meet the demand that receiver is charged when work again.Main frame is connected with flat plane antenna by radio frequency cable, completes transmission, reception and information checking and the checking of information.Receiver adopts between serial ports, two kinds of bluetooths and computer and carries out communication channel.Simultaneously, the strong and weak indication of Big Dipper satellite signal, power supply indication, communications status indication are monitored the receiver operating state.
The working method that receiver had both directly been powered by lithium battery, also designed corresponding straight charging circuit, can meet the demand that receiver is charged when work, simultaneously, for the capacity of pilot cell, designed the function of battery electric quantity indication.
Whole receiver adopts durable Nylon-1010, and completes injection molded, and antenna, battery and other modules all are sealed in housing, simultaneously, adopts waterproof sealing connector, housing design fixture and tie string hole.
And, in the place of the information such as satellite communication information (indication as strong and weak as signal), power supply indication, communication indication, housing has carried out transparent processing, has both prevented the invasion of water, has reached again the effect of indication.
Following part is software section of the present utility model:
The software of the receiver of the present embodiment forms structure, and the receiver end application software comprises the data real-time monitoring module, and data decompresses, coding module, and the data automatic reception, put the real-time Presentation Function module of information automatically in storage; The server end application software is by Information Compression, coding module, and information processing, remote control modules etc. partly form.
Receiver end, by main generation of interfaces querying command, is notified main program, and main program is put into serial ports by order, by the big-dipper satellite channel, sends to server end.Server end receives the querying command that receiver end sends, and by calling the inquiry subprogram, the query-relevant data file, return success message, and Query Result is preserved and record.Main program is received poll-final message, calls code subroutine and is encoded.Send end after end-of-encode to main program.After main program is received end-of-encode message, notice serial ports transmission program is transmitted.
It is running environment that the software that matches be take WindowsXP, C#, SQL database management software, adopts the B/S structure, sets up the application software be complementary with above-mentioned hardware device, and this software kit is containing the application software of server end and application software two parts of receiver end.The receiver end application software comprises the data real-time monitoring module, and data decompresses, coding module, and the data automatic reception, put the real-time Presentation Function module of information automatically in storage; The server end application software is by Information Compression, coding module, and information processing, remote control modules etc. partly form.Communication modes of the present utility model adopts the Beidou satellite communication scheme, formulates the communications protocol between server end and receiver.
The big-dipper satellite location of communication system, comprise that Big Dipper Aerospace Satellite, network management center, terminal use form.Big Dipper Aerospace Satellite part is comprised of 3 geostationary satellites, is responsible for carrying out the double-direction radio signal of telecommunication relay task between ground central station and user terminal.Network management center mainly complete and satellite between the processing of uplink and downlink data; The service request that all types of user is sent responds processing; Complete the work for the treatment of of whole user's locator datas and the exchange work of communication data, and calculating resulting customer location and giving respectively relevant user through the Content of Communication of exchange; The transmit leg user is communicated to receipt confirms simultaneously.
