Description
Technical field
Of the present utility modelly relate to a kind of electric locomotive automatic passing over of neutral section active signal generator.
Background technology
At present, electric locomotive automatic passing neutral section system (such as: during locomotive entering garage) when locomotive is static will accomplish that major tune-up and overall process are tested now also very difficult, although have self-checking equipment in system, operating state during the undue phase section of locomotive can be simulated, but vehicle-mounted inductor does not produce induced signal, just self-checking equipment is sent an analog signal to system and is substituted.Cause service work to have human injury's danger, carry inconvenience, overhaul efficiency is low.
Summary of the invention:
In order to solve the problem, the purpose of this utility model is to provide the effect of a replacement permanent magnet, wire signal generator, allow generator near the undue Phase Receiver inductor of electric locomotive, vehicle-mounted inductor can receive an amplitude, wave band, the similar simulated telecommunication number that permanent magnet is the same excessively of fabric width.And easy to carry, light and handy, non-hazardous electric locomotive automatic passing over of neutral section active signal generator.
The technical solution of the utility model is: electric locomotive automatic passing over of neutral section active signal generator, and this source signal generator comprises monopulse generator, differential circuit, pulse width modulation circuit, shaping circuit, transmission control device, transmission coil and power module;
Wherein, described monopulse generator is connected with described differential circuit circuit, described differential circuit circuit is connected with described pulse width modulation circuit, described pulse width modulation circuit is connected with described shaping circuit, described shaping circuit is connected with described transmission coil, described transmission control device and described monopulse generator control connection, described power supply is that described monopulse generator, differential circuit, pulse width modulation circuit and shaping circuit are powered.
The beneficial effects of the utility model are: owing to adopting technique scheme, it is little that the utility model signal generator has volume, lightweight, be easy to carry use, is under situation is stopped in storehouse, overhaul and test the desirable instrument of automatic neutral-section passing system, use permanent magnet to be a a progressive step relatively, eliminate human injury's danger, easy to carry, easy to use, improve overhaul efficiency.
Accompanying drawing explanation
Fig. 1 is logical construction block diagram of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further.
As shown in Figure 1, for the logical construction block diagram of the utility model electric locomotive automatic passing over of neutral section active signal generator, this source signal generator comprises monopulse generator, differential circuit, pulse width modulation circuit, shaping circuit, transmission control device, transmission coil and power module;
Wherein, described monopulse generator is connected with described differential circuit circuit, described differential circuit circuit is connected with described pulse width modulation circuit, described pulse width modulation circuit is connected with described shaping circuit, described shaping circuit is connected with described transmission coil, described transmission control device and described monopulse generator control connection, described power supply is that described monopulse generator, differential circuit, pulse width modulation circuit and shaping circuit are powered.
During use, transmission coil is enclosed within the vehicle-mounted inductor shell of electric locomotive automatic passing neutral section system, press transmission control device, monopulse generator sends pulse signal and sends to differential circuit, pulse signal is converted to single pulse signal forward or backwards by microcircuit, signal after conversion is by shaping circuit shaping, remove unwanted part, waveform is made to meet actual requirement, signal after shaping sends by sending coil, vehicle-mounted induction coil obtains an amplitude and is greater than 5v, pulsewidth (7-15) ms, adjustable individual pulse current signal, start neutral-section passing system work.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
