Preferably, described multi-path power divider is 16 road power splitters.
Preferably, described multi-channel serial port Ka Wei 16 road serial port boards.
The beneficial effects of the utility model are: the utility model adopts gps signal generation board to be installed on PXI1033 cabinet the inside, can simulate the signal of 5～10 gps satellites, due to need of production, use multi-path power divider that analog output signal is divided into to 16 roads by multi-path power divider is transferred in 16 detection model machines simultaneously, for each test prototype is carried out to record, edit and record into file, the scanner connected by server before test will first be scanned the label on every test prototype, so that system log (SYSLOG) initial situation, data after the test prototype test are input to the enterprising line number of server according to one's analysis and record by 16 road serial port boards, finally by printer printed report and display, show that whether data are qualified to tester's intuitive judgment test prototype, what this printed report showed is the result of every test in this test, the pilot lamp output steering order that server also can arrange every test prototype side by the digital IO expansion interface simultaneously, good or bad with what show test results, the utlity model has measuring accuracy high, simple operation and other advantages.
The accompanying drawing explanation
Fig. 1 is square frame connection layout of the present utility model;
Fig. 2 is structural drawing of the present utility model.
In 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 IO expansion interface; 9, test station.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is described in further detail, it should be noted that, the direction term of mentioning in following examples, for example " upper and lower, left and right " are only the directions with reference to accompanying drawing, therefore, the direction term of use is not to be used for limiting the utility model for illustrating.
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 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 be divided into the signal that multichannel power is equal to the signal of gps signal generator 2 outputs and output to 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 guide plane.The signal output port of described test prototype 6 is connected with described multi-channel serial port card 4, and whether test prototype 7 is located successfully and all can be exported corresponding signal, and the project of its test comprises the information such as longitude, latitude and height.After test prototype 6 receives signal, can judge corresponding position relationship, suppose not receive coherent signal due to the environment of simulation, 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, server carries out relevant record, by display 5, shows the test prototype 6 that can locate, 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 IO expansion interface 8.Described digital IO expansion interface 8 is connected with the pilot lamp 7 of test station 9 on test prototype 6.
Further, described multi-path power divider is 16 road power splitters.
Further, described multi-channel serial port Ka Wei 16 road serial port boards.
Below sketch operation and the course of work of native system:
At first set gps signal generator 2 for simulating the signal of 5～10 gps satellites, server 4 is controlled gps signal generator 2 and is started to produce simulating signal, as the cabinet the superiors in Fig. 1 arrange computor-keyboard 1, in order to the manual control system, starts.Due to need of production, use power splitter that analog output signal is divided into to 16 that the equal signal of 16 road power transmits by multi-path power divider 3 simultaneously and detect in model machines, each test prototype 6 is all to be equipped with bar-code label simultaneously.For each test prototype 6 is carried out to record, edit and record into file, the scanner connected by server 4 before test will first be scanned the label on every test prototype 6, so that system log (SYSLOG) initial situation, the corresponding test prototype 6 that connects of Shi， 16 road power splitters that need know, 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, open the testing software on server 4, wait for and having tested.The test data of test prototype 6 is input to the enterprising line number of server 4 according to one's analysis and record by 16 road serial port boards, finally by display 5, show that whether data are qualified to tester's intuitive judgment test prototype 6, the project of these server 4 tests only has whole tested successes, last reporting the result can show successfully with pilot lamp 7, otherwise only have 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 prototypes of digital IO expansion interface, 6 sides, every test prototype 6 connects two pilot lamp 7, green representative test is passed through, the red test failure that means, to show the good or bad of test result, whether test prototype 6 is housed on test station 9 and also by digital IO expansion interface 8, feeds back to server.Therefore the utlity model has measuring accuracy high, texts simple to operate.
The above not imposes any restrictions this novel technical scope, and all any modification, equivalent variations and modifications of above embodiment being done according to the utility model technical spirit all still belong in the scope of this novel technical scheme.
