Summary of the invention
The technical problem to be solved in the present invention provides many stars of GPS emulation test system, and the precision height of the present invention's test is simple to operate, can simulate multiple satellite-signal, and the result of test shows with the form of datumization.
Be achieved through the following technical solutions above-mentioned purpose:
Many stars of GPS emulation test system, comprise gps signal generator, multi-path power divider, multi-channel serial port card and server, described server is connected with described gps signal generator, described gps signal generator is connected with described multi-path power divider, each road output terminal of described multi-path power divider is connected with a test prototype, the signal output part of described test prototype and described multi-channel serial port card connection, described multi-channel serial port card is connected with described server.
Preferably, described server is connected with one scan rifle, printer and display respectively.
Preferably, described server also is connected with a digital input and output expansion interface.
Preferably, described digital input and output expansion interface connects the pilot lamp of test station on the test prototype.
Preferably, described multi-path power divider is 16 road power splitters.
Preferably, described multi-channel serial port card is 16 road serial port boards.
The invention has the beneficial effects as follows: the present invention adopts gps signal generation integrated circuit board to be installed on PXI1033 cabinet the inside, can simulate the signal of 5～10 gps satellites, need owing to produce, using multi-path power divider that analog output signal is divided into 16 the road by multi-path power divider is transferred in 16 detection model machines simultaneously, for each test prototype is carried out record, edit and record into file, the scanner that connects by server before test will scan the label on every test prototype earlier, so that system log (SYSLOG) initial situation, data after the test prototype test are input to the enterprising line data analysis of server and record by 16 road serial port boards, show by printer printed report and display whether data are qualified to tester's intuitive judgment test prototype at last, that this printed report shows is the result of every test in this test, server also can be exported steering order to the pilot lamp that every test prototype next door arranges by digital input and output expansion interface simultaneously, good or bad with what show test results, the present invention has measuring accuracy height, simple operation and other advantages.
Description of drawings
Fig. 1 is square frame connection layout of the present invention;
Fig. 2 is structural drawing of the present invention.
Among the figure 1, computor-keyboard; 2, gps signal generator; 3, multi-path power divider; 4, multi-channel serial port card; 5, display; 6, test prototype; 7, pilot lamp; 8, digital input and output expansion interface; 9, test station.
Embodiment
The invention will be further described below in conjunction with accompanying drawing and preferred embodiment, need to prove, the direction term of mentioning in following examples, for example " upper and lower, left and right " only are directions with reference to the accompanying drawings, therefore, the direction term of use is to illustrate not to be to limit the present invention.
As shown in Figure 1, many stars of GPS emulation test system, comprise gps signal generator 2, multi-path power divider 3, multi-channel serial port card 4 and server, described server is connected with described gps signal generator 2, in PXI1033 cabinet the inside a 5671GPS signal generation integrated circuit board is installed and is formed gps signal generator 2.Described gps signal generator 2 is connected with described multi-path power divider 3, multi-path power divider 3 can output to the signal that the signal demultiplexing power of gps signal generator 2 outputs equates respectively on each corresponding test prototype 6, and described multi-path power divider 3 each road output interface are connected with a test prototype 6.In actual applications, this test prototype 6 is the multimedia guiding aircraft.The signal output port of described test prototype 6 is connected with described multi-channel serial port card 4, and whether test prototype 7 locatees success all can be exported corresponding signal, and the project of its test comprises information such as longitude, latitude and height.After test prototype 6 receives signal, can judge corresponding position relation, suppose because the environment of simulation does not receive coherent signal, the relevant position of its judgement just can't be located, when test prototype 6 feeds back to server by multi-channel serial port 4 cards, the record that server is correlated with shows the test prototype 6 that can locate by display 5, and described multi-channel serial port card 4 is connected with described server.
Further, described server is connected with one scan rifle, printer and display 5 respectively.Described server also is connected with a digital input and output expansion interface 8.The pilot lamp 7 of the test station 9 on described digital input and output expansion interface 8 and the test prototype 6 is connected.
Further, described multi-path power divider is 16 road power splitters.
Further, described multi-channel serial port card is 16 road serial port boards.
Below sketch operation and the course of work of native system:
At first set gps signal generator 2 and be used for the signal of 5～10 gps satellites of simulation, server 4 control gps signal generators 2 begin to produce simulating signal, as the cabinet the superiors among Fig. 1 computor-keyboard 1 are set and begin in order to the manual control system.Owing to produce to need, use power splitter that analog output signal is divided into 16 that signal that 16 road power equate transmits simultaneously by multi-path power divider 3 and detect in the model machines, each test prototype 6 all is to be equipped with bar-code label simultaneously.For each test prototype 6 is carried out record, edit and record into file, the scanner that connects by server 4 before test will scan the label on every test prototype 6 earlier, so that system log (SYSLOG) initial situation, what need know is, the corresponding test prototype 6 that connects of 16 road power splitters, and it is numbered 1 ~ 16, connect by 16 road serial port boards are corresponding, make the server 4 can 1 ~ No. 16 test prototype 6 position of accurate recording.After connection finishes, open the testing software on the server 4, wait for testing and finish.The test data of test prototype 6 is input to server 4 enterprising line data analysis and records by 16 road serial port boards, show by display 5 whether data are qualified to tester's intuitive judgment test prototype 6 at last, the project of these server 4 tests has only whole tested successes, last reporting the result can show success with pilot lamp 7, otherwise has only unsuccessful.Printer can print unsuccessful test report for analyzing and maintenance.Server 4 is the pilot lamp 7 output steering orders that arrange by 8 pairs of every test prototype 6 next doors of digital input and output expansion interface, every test prototype 6 connects two pilot lamp 7, green representative test is passed through, red expression test failure, to show the good or bad of test result, whether test prototype 6 is housed on the test station 9 also feeds back to server by digital input and output expansion interface 8.Effects such as therefore the present invention has the measuring accuracy height, and is simple to operate.
The above is not that technical scope of the present invention is imposed any restrictions, all according to the technology of the present invention essence to any modification, equivalent variations and modification that above embodiment does, all still belong in the scope of technical scheme of the present invention.
