Hvad skal tilslutningerne til GPS, GSM, MP3, H-bro og stepmotor bruges til?
Jeg har selv lavet et relæprint, der opfylder mine behov. Dvs. udover de
normale funktioner tænder kørelys når nøglen sættes i og viskeren har tre
stillinger: pausedrift, lav hastighed og høj hastighed. Jeg bruger stort set
kun pausedriften.

Dette betyder at man kun skal sende et print til den dyre producent,
mens alle testprints kan laves på køkkenbordet...
= mindre udgifter

Description
48V storage battery energy meter,digital-volt-meter ,odometer,speedometer,electronic vehicle liquid crystal meter.
This type liquid crystal meter can monitor storage voltage, energy ,vehical?s speed and mileage
wheel?s length can be set with the range of 1000mm-2000mm, pulse number which is generated by each time the wheel turn round can also be set with the range of 1-99 .A lot of odometers nowadays set the wheel?s length by potentiometer adjustment
this method is itself inaccurate cause no one can make sure the accurate number it sets to ,While our wheel?s length is set by key, the electric energy calculation is according to storage battery?s discharge curve conbined charge-discharge time elements to calculate the state of charge,which is the real digital energy meter, It can be widely used in electric cars electric touristry electric fork lift electric tricycle electric bicycle and UPS etc fields .
(when electric energy is 100%,ten black checks are all tured on;when electric energy is 20%,the foremost two black checks alarm alternatively).
Most of the so-called energy meter is actually a voltmeter presently,(which is judged by some comparators according to some being set comparation voltages in general ,)this way may show a relatively great deviation(voltage down when battery loading,no-loading voltage up), since the current becomes larger and voltage drops quicker once speed-up or started, ?electric quantities? drops quicker as well.
USAGE:
1.dispaly the animation: QIU SHI DESIG when LCD is starting with the animation moving out from the left of the screen
2.wheel?s length can be set with the range of :1000mm-2000mm, setting method is as follows:pessing the leftmost function key in the above picture will show the interface below,
press down the middle key ,wheel?s length begin increasing,when increase to maximum value:2000mm it returns to minimum value:1000mm.
3.pulse number which is generated by each time the wheel turn round can be set ,pressing down the leftmost function key again will show the interface below
press down the middle key ,pulse number can be set arbitrarily within the range:1-99 ,and all setting are self-protective.instrument returns to nomal working intersuface when press the function key again.
4.Total mileage accumulation,its maximum is 99999.9KM(100000KM),and length of roads will be preserved when power is cut off
5.Instrument power supply: The defaults voltage is 8-16v ,if any other supply voltage please indicate us ,60v is the maximum voltage to support this instrument presently speaking.if beyond 60v supplying voltage,please connect the wires according to the picture below.
6.The instrument can measure the voltage within the range of 9v-99v,please indicate us if more wide voltage measurement needed.
7.The measurement of speed adopted speacial speed acquistion module,this measurement is more accurate,which can support maximum;999KM/H.
8.method of instrument wires connecting is as following picture;
blue wire: connect the positive terminal of the instrument power supply
black wire:connect the negative terminal of the instrument power supply
green wire:connect the speed signal line
our?s speed acquistion module can measure the Hall voltage within the range of 0-30v,it can be widely used for all kinds of vehicals which speed is measured by Hall .
9.instrument consumption:less than 50mA
10.instrument mesurement:80*36*25mm
11.This type liquid crystal instrument?s back-litht is grey,it can even see clearly both in the sunlight or evening.dispalying effect is better.
