Detailed description of the invention
The driver controller handle of this utility model Integrated Light electric-type forestalling switch includes driver controller handle and peace
It is contained in the hollow handle connecting rod of driver controller handle base；The end face of driver controller handle has visible ray filter plate；Handle
Head hollow, is embedded with infrared-type proximity transducer circuit；Infrared-type proximity transducer circuit and locomotive vigilance device electricity
Road is connected.
Below in conjunction with accompanying drawing and enforcement example, this utility model is described in detail.
As shown in Figure 1: be embedded with translucent optical filter 1 at driver controller handle tip, the effect of optical filter is to filter
Infrared ray photoelectric on visible ray circuit board assemblies embedded on handle 3 receives the impact of audion 5.Pass through in the lower section of optical filter
2 screws 2 are provided with circuit board assemblies 3.Infrared light emitting diode 4 and infrared receiver audion 4 is had on circuit board assemblies 3
And signal processing circuit.
The schematic diagram of infrared-type proximity transducer circuit is shown in Fig. 3.The working power of infrared-type proximity transducer circuit
Being retrieved from the DC24V power supply of rail transit rolling stock driver controller dial illumination, this is easily able in actual applications
's.24V power supply through resistance R1 current limliting rear drive infrared light emitting diode send wavelength be about the single mode of 950nm can not show
Outer linear light.This infrared ray can pass through the filter plate 1 of handle tip, when driver does not operate handle, does not has Infrared to reflect
Turn round and stretch out the hand handle.When hands Proximity operation the handle (≤1mm) of driver, after HONGGUANG line is sent by infrared light emitting diode 4, run into department
Tractor driver slaps, and is reflected back infrared electro audion 5.
Signal processing circuit includes operational amplifier U1, resistance R4, resistance R6, potentiometer R3, resistance R7, resistance R2 and electricity
Resistance R6, U1 are the operational amplifier working in voltage comparator, and resistance R6 introduces positive feedback from the outfan of U1, constitute window slow
Stagnant comparator.
Due to the distance by reverberation body detecting distance, the skin of hand surface differences of different people, and whether wear glove etc.
Situation is different, the HONGGUANG line reflected number be different, it is therefore desirable to voltage ratio is adjusted compared with the threshold value judged
Joint and setting, reach optimal Detection results.If greater than 1mm, then be exactly that staff is also not exposed to handle, forestalling switch
State just there occurs change, this be not to.Generally, distance is less than 1mm, just it is believed that staff can be abutted against
Touch on handle.To this end, the negative input of operational amplifier U1 of the present utility model is by resistance R4 and potentiometer R3 even
Connecing, potentiometer R3 compares the setting of threshold value for operational amplifier, by the inspection of regulator potentiometer R3 regulation signal processing circuit
Find range from.
The positive input of operational amplifier U1 is connected with the emitter stage of infrared electro audion 5 by resistance R5, infrared
The emitter stage of phototriode 5 is also by resistance R7 ground connection；When there being infrared reflection to return, the voltage on R7 can increase, warp
Oversampling circuit comparator U1 output two kinds of level of height, to embody vigilant operation change output.Rolling stock is detecting vigilant change
After changing output, carry out time limit judgement and process, the most vigilant operation nothing according to the safety regulation of vigilant operation
Change, i.e. drives loudspeaker and the display lamp etc. of drivers' cab that driver sends warning information, as after certain time vigilant operation still
Unchanged, then start emergency safety stop mechanism.
In order to improve the reliability of this utility model infrared-type proximity transducer circuit work, this utility model infrared ray
Whole components and parts all layouts of formula proximity transducer circuit in handle grooves, by loop inner introduce interference may be relatively
Little, in contrast be that DC24V power line attracts from the dial illumination power supply of rail transit rolling stock, length of arrangement wire
Relatively big, easily scurry into overvoltage interference, therefore positive and negative of power supply is provided with Zener diode D2, to prevent overvoltage interference from causing device
Part U1 and D1 and Q1 scaling loss.
It addition, as in figure 2 it is shown, for avoid Infrared approach in intracavity of handle to pass through, at infrared emitting two
Have between pole pipe 4 and infrared electro audion 5 intercept infrared ray pass through every light block 8, groove surface of internal cavity has done reflective simultaneously
The black plastic-blasting coating that rate is extremely low.
