Number, fixed and variation rate travel signal and two-position ais signal.
Background technology
Navigation equipment is applied very extensive at present, and various types of navigation instruments are equipped with from vehicle to ship and are set
It is standby.When the failure of these equipment is how to judge that the missing of satellite-signal or the failure of navigation system itself are equipment
The problem of maintenance personnel frequently encounters and is difficult rapid diagnosis and processing.
The working efficiency for improving navigation system devices maintenance personnel is improve plant maintenance level and efficiency main
One of measure.
Invention content
The present invention provides a kind of portable navigation signal simulators, improve the work of navigation system devices maintenance personnel
Efficiency reduces the labor intensity of maintenance personnel.
Technical solution of the invention is as follows：

Electric energy is provided for the circuit of the present invention, the supply voltage of battery pack is promoted operating voltage everywhere by power booster circuit, respectively
Supply microcontroller, RS422 output interfaces and RS232 output interfaces；Buzzer, LED indication lamp group and selection key group, all with list
Piece machine connects.Buzzer reminds operating personnel for giving a warning the sound；The working condition of selection key group control single chip computer, choosing
Select key group by key pressing after, information is transferred to microcontroller；
After microcontroller work, driving buzzer sends out the sound and reminds operating personnel, while driving four kinds of LED indication lamp group
Indicator light：GPS indicator lights, HDT indicator lights, VBW indicator lights and AIS indicator lights；Each indicator light is lighted, is flickered in turn successively, really
Surely which kind of analog functuion is selected, that analog information is generated.
Single-chip simulation generates the following signals for meeting NMEA0183 formats：
The GPS signal of (1) two determining position；
(2) the fixed and bow that changes is to signal HDT；
(3) rate travel signal VBW that is fixed and changing；
The ais signal of (4) two groups of different locations；
The above-mentioned analog signal that microcontroller generates is converted into the output of RS422 formats, RS232 outputs by RS422 output interfaces
The analog signal that microcontroller generates is converted into the output of RS232 formats by interface.
The present invention can be connect with the traffic rate of 4800~38400bps of artificial selection, RS422 output interfaces and RS232 outputs
Mouth has anti-short-circuit function.
The present invention is portable instrument, is carried, and structure design is simple, easy to operate, and use reliability is higher.Test
With the working condition for verifying various navigation equipments, the intervention without staff can be according to preset program automatic work, can be with
Inspection, the test for quickly completing navigation equipment performance, largely reduce the labor intensity of plant maintenance personnel, improve
The working efficiency of plant maintenance personnel.
Description of the drawings
Attached drawing 1 is the structural schematic diagram of the present invention.
In Fig. 1：1 power switch；2 RS422 output interfaces；3 RS232 output interfaces；4LED indicator lamp groups；5 selections are pressed
Key group；6 buzzers；7 microcontrollers；8 battery packs；9 power booster circuits.
Specific implementation mode
Microcontroller is responsible for the responsibility of the generation of signal, output, display and power and energy.When selection key group have button by
After lower, information is transferred to microcontroller；MCU driving buzzer sends out the sound and reminds operating personnel, while driving LED indication
Corresponding LED light is lighted or is flickered in lamp group, and different analog informations is generated to represent；Simultaneously according between the regular hour
Analog information is exported by RS422 output interfaces and RS232 output interfaces every simultaneously.
Battery pack is responsible for providing power supply to whole system.Power booster circuit is responsible for the power booster of battery to entire system
It unites required working power.
In use, operating personnel install battery pack, connects corresponding equipment to RS422 output interfaces or RS232 and export
Interface.It turns on the power switch, power booster circuit is started to work is promoted to microcontroller operating voltage by battery voltage；Microcontroller
Start self-test work.When self-test works, LED indication lamp group is all lighted, and one sound of buzzer call, later, LED indication lamp group is complete
Extinguish in portion.After self-test works, the GPS indicator lights of LED indication lamp group are always on, and the traffic rate " bps " of LED indication lamp group refers to
Show that lamp is always on, shows that self-test of the present invention finishes and start to work normally.
When needing other analog signals, corresponding behaviour may be selected by " Fun " button of selection key group in operating personnel
Make function.When operating personnel press " Fun " button of a selection key group, one sound of buzzer call, LED indication lamp group
" GPS ", " HDT ", " VBW " and " AIS " indicator light is lighted, is flickered to determine which kind of analog functuion selected in turn successively.Operator
When member is by (5) " SIO " button of selection key, " bps " indicator light of one sound of buzzer call, LED indication lamp group is always on, flickers
Alternately." bps " indicator light is " bright " to indicate that current traffic rate is 4800, and " flicker " indicates that current traffic rate is 38400.
