Abstract
The utility model discloses a kind of signal generation apparatus for detecting locomotive speed sensor, including shell and the motor support base, motor, the measure speed gearses that are built in enclosure, motor support base is located at the bottom of shell, the upper end connection motor of motor support base, motor is connected with measure speed gearses, support with adjustable is provided with positioned at the upper end of shell and through shell, support with adjustable lower end is provided with sensor probe, gap between sensor probe and measure speed gearses is adjusted by support with adjustable, the side positioned at shell is provided with button switch.Using this signal generation apparatus, under locomotive and speed measuring fluted disc inactive state, to simulate the square-wave signal of speed measuring fluted disc generation, so as to detect the performance and wiring state of velocity sensor.Can detection sensor whether work, solve again conventional locomotive debugging plan cannot detection sensor terminals and microcomputer respective channel whether the correct problem of wiring.
Description
Technical field
The utility model is related to locomotive speed sensor technical field, and in particular to one kind is sensed for detecting locomotive speed
The signal generation apparatus of device.
Background technology
All operating speed sensors monitor locomotive running speed in electric locomotive and diesel locomotive.The work that sensor tests the speed
It is that sensor probe end is fixed on the speed measuring fluted disc of locomotive traction motor as principle, speed measuring fluted disc is synchronous with motor sport to be turned
Dynamic, sensor obtains square-wave signal by the speed measuring fluted disc for rotating；The terminals of sensor are connected to locomotive microcomputer, by microcomputer
Square-wave signal is converted into tachometer value.There are 4~6 velocity sensors on a usual locomotive, they are all connected on the correspondence of microcomputer
On passage
The scheme of existing detection speed sensor is that in locomotive enters the commissioned journey of row line, observation locomotive display screen is
No display speed value, judges whether velocity sensor works with this.
The premise of existing detection speed sensor plan is that locomotive will be kept in motion, and can only now detect sensor
Whether work, but the sensor terminals of different traction electric machine whether wiring cannot correctly be detected with microcomputer respective channel.
The content of the invention
The utility model provides a kind of signal generation apparatus for detecting locomotive speed sensor, solves velocity pick-up
Device terminals and microcomputer respective channel whether the correct undetectable problem of wiring.
The technical scheme that the utility model is used is the signal generation apparatus for detecting locomotive speed sensor, including
Shell and the motor support base, motor, the measure speed gearses that are built in enclosure, motor support base are located at the bottom of shell, motor support base
Upper end connection motor, motor is connected with measure speed gearses, and support with adjustable is provided with positioned at the upper end of shell and through shell,
Support with adjustable lower end is provided with sensor probe, between being adjusted between sensor probe and measure speed gearses by support with adjustable
Gap, the side positioned at shell is provided with button switch.
The beneficial effects of the utility model are：Using this signal generation apparatus, in locomotive and the static shape of speed measuring fluted disc
Under state, the square-wave signal of speed measuring fluted disc generation is simulated, so as to detect the performance and wiring state of velocity sensor.Can examine
Survey sensor whether work, solve again conventional locomotive debugging plan cannot detection sensor terminals be with microcomputer respective channel
The no correct problem of wiring.
Brief description of the drawings
Fig. 1 is the utility model signal generation apparatus schematic diagram.
Marked in figure；1st, button switch, 2, shell, 3, support with adjustable, 4, sensor probe, 5, measure speed gearses, 6, electricity
Machine, 7, motor support base.
Specific embodiment
Utility model is described further in conjunction with accompanying drawing 1, the utility model as a signal generation apparatus, by
Shell 2, support with adjustable 3, button switch 1, battery, motor 6, measure speed gearses 5, motor support base 7, sensor probe 4 etc. are constituted.
Sensor to be measured is arranged on support with adjustable 3, button switch 1 is pressed, drives measure speed gearses 5 to rotate come mould by motor 6
Intend the rotation of locomotive traction motor speed measuring fluted disc, the rotating speed of correspondence traction electric machine can be now observed on microcomputer.
On actual locomotive, 4 ends of locomotive speed sensor probe are located on traction electric machine speed measuring fluted disc, the wiring of sensor
End is connected in locomotive microcomputer.Completed in locomotive general assembly, during into the static debugging stage, operator pops one's head in velocity sensor
4 pull down from traction electric machine, on support with adjustable 3, ensure that by adjusting height of support probe and device test the speed
Gap between gear 5.Button switch 1 is pressed, checks corresponding ports whether there is rate signal in locomotive microcomputer.For detection machine speed
Spend the wiring state of sensor.
