When gauge equaled standard gauge (being 1435mm), slide-wire rheostat mediated.At this moment, resistance R X between cb
1Equal resistance R R between ca
1Voltage Vcd is zero between cd, and the gauge deviate that demonstrates is zero.
When gauge overgauge gauge, the slide key of slide-wire rheostat glides to left end in spring action.At this moment, RR
1Greater than RX
1, so cd between voltage Vcd be on the occasion of, demonstrate the deviate of the slacking of gauge.
When gauge during less than standard gauge, the feather key on the slide rheostat glides to right-hand member in spring action.On LCD, demonstrate the deviation that gauge dwindles.
The horizon sensor of unevenness check system has adopted liquid pendulum-type horizon sensor, and the liquid in this sensor is lithium chloride solution, checks principle as shown in Figure 5.
Because of the conductive characteristic that lithium chloride solution had, make the Rx that has a resistance between horizon sensor electrode c and b
1, RR has a resistance between electrode c and a
1, respectively with resistance R
1And resistance R
2Leveling resistance W forms the bridge-type comparison circuit.
When the spirit bubble of sensor during in the centre position, resistance R R
1=RX
1, the bridge no-output, voltage Vcd is zero between c, d, the unevenness deviate that demonstrates on LCD is zero.
When the spirit bubble of sensor was tilted to the left, spirit bubble was shifted to right-hand member.At this moment, resistance R R
1＞RX
1, electric bridge has output.Voltage Vcd is a negative value between c, d.
When the spirit bubble of sensor was tilted to the right, spirit bubble was shifted to left end.At this moment, resistance R R
1＜RX
1, electric bridge has output.Between c, d voltage Vcd be on the occasion of.
The difference in height check system has adopted the principle of some inspection artificial line inspection to check the difference in height of circuit.Because the train wheelbase is 15.1m, the every walking of inspection trolley 3.02m, alarm sensor just send once and report to the police.When reporting to the police for the 5th time, the inspection trolley 15.1m=5 * 3.02m that walked meanwhile, will demonstrate the concrete numerical value that whether transfinites on LCD.If transfinite, alarm sensor will be reported to the police automatically.Its circuit theory as shown in Figure 6.
When horizontal wheels was rotated a week (girth 251.66), magnet was given signal of Hall switch.This signal enters counter A sum counter B respectively and has the records of distance by the log with realization.When checking that distance reaches 3.02m, counter B exports letter, and makes the work of news Chinese percussion instrument by photo-coupler.Meanwhile, counter A also exports a signal and gives rate multiplier.After two surface-mounted integrated circuit decodings, by the liquid crystal display displays mileage.
Because this inspection trolley Ministry of State Security has adopted the COMS circuit, so the power consumptive province simultaneously because of having adopted liquid crystal display, so complete machine can adopt 9V battery-powered, and is provided with power switch, is used for controlling reactive power consumption.
