Block the electrical connection of corresponding voltage output port, the frequency output terminal of voltage frequency conversioning circuit respectively with vehicle arrangement rate signal
The corresponding frequencies input electrical connection of receiving unit.The shortcoming of prior art 2 is that speed signal simulation device needs outside
Working power is provided for it, is not suitable for place conversion and uses, designed circuit cost is higher, it has not been convenient to safeguard.Above-mentioned speed
Analogue means can not complete the transmission of rate signal to different rate signal reception devices respectively.Design used in circuit into
This is higher, it has not been convenient to safeguard.
The content of the invention
The utility model provides a kind of multichannel locomotive speed analogue means, realizes the static state of locomotive speed detecting system
Debugging, accomplishes to fix a breakdown in advance.
The technical scheme that the utility model is used is multichannel locomotive speed analogue means, including is believed for analog rate
Number multivibrator, in addition to external control switch 1,2,3, for controlling speed analogue means to output signals to digital-to-analogue respectively

The beneficial effects of the utility model are：(1) when realizing locomotive static state, detection tune is carried out to speed detection system
Examination, it is ensured that failure is early found, early to exclude.Speed signal system failure is detected when avoiding locomotive test run, so as to cause locomotive
" secondary test run ", the loss of caused human and material resources.(2) in locomotive static debugging, produced by speed analogue means steady
Fixed, controllable rate signal is input in microcomputer, it is ensured that the condition of locomotive field weakening experiment, it is to avoid manual rotation's spindle nose
Mode produce rate signal as experimental condition.Manpower is saved, the manual work time is shortened.(3) this speed simulation
Device volume is small, lightweight, be convenient for carrying, and adapts to various Active workings.And the device provides power supply by locomotive, it is not necessary to outside
Power supply is supplied, facilitates commissioning staff to debug.(4) the speed analogue means designed by can simulate the rate signal of all ranges,
And the rate signal of simulation is transferred in microcomputer, digital-to-analogue box, monitoring by switching control.
Brief description of the drawings
Fig. 1 is multichannel locomotive speed analogue means schematic diagram.
Fig. 2 is multichannel locomotive speed analogue means multi-channel switch circuit diagram.
Embodiment
Utility model is described further in conjunction with accompanying drawing 1 and accompanying drawing 2, in locomotive normal driving process, locomotive speed
Degree sensor by produce rectangle square-wave signal be transferred to locomotive monitoring system, digital-to-analogue box, microsystem TCMS carry out display at
Reason.Sensor produces square-wave signal, is respectively transmitted in said apparatus.Designed multichannel speed analogue means, such as Fig. 1 institutes
Show using 555 chips, slide rheostat, electric capacity as core, design is a kind of can be with the multivibrator of analogue speed signal.It is this many
Harmonic oscillator is also known as astable multibrator, the output state that it does not stablize, only two temporary stable states.It is in circuit a certain
After temporary stable state, another temporary stable state is turned to through can voluntarily trigger after a while.Two temporary stable states voluntarily mutually conversion and it is defeated
Go out series of rectangular ripple.By adjusting the value of slide resistor, electric capacity, cycle and the duty of square-wave signal can be adjusted indirectly
Than, and then can simulate the speed of different numerical value, so multivibrator can be used as square-wave generator, therefore can be for simulation
