Summary of the invention
The object of the invention is to provide a kind of combined type intelligent instrument for battery-driven car, its by battery electric quantity table, hour meter, malfunction coefficient instrument neutralization get up, saved cost of manufacture, make install more compact, installing space is less.
In order to solve these problems of the prior art, technical scheme provided by the invention is:
A kind of combined type intelligent instrument for battery-driven car, the micro controller system for center-control is provided with in intelligent instrument, power input is accessing micro controller system with two-stage mu balanced circuit, electricity sample circuit, power-fail detection circuit after being connected respectively, hour meter enable signal be delivered to micro controller system by sample circuit, fault collection signal is delivered to micro controller system by sample circuit; Be provided with the input port for detecting external device fault in combined type intelligent instrument, when external device breaks down, combined type intelligent instrument is reported to the police by LCD display unit display failure code, LED instruction.
For technique scheme, contriver also has further optimal enforcement scheme.
As optimization, for starting the key switch input of battery-driven car, a road is to the electro heat module for power supply of instrument display screen, and another road is connected to the backlight module of instrument LCD display, is also delivered to micro controller system simultaneously, for judging whether key switch is opened.Described LCD display unit is connected with micro controller system by LCD driving circuit.
As optimization, in intelligent instrument, be provided with relay output unit, when intelligent instrument detects electricity lower than setting value by electricity sample circuit, disconnect relay in intelligent instrument and connect, for promoting latch functions.
Further, after key switch is opened, first LCD display unit shows current accumulative hours, and time delay 5 seconds; After 5 seconds, LCD display unit display battery electric quantity percentum, indication range is 0% ~ 100%; Once intelligent instrument detects that external device produces fault, at this moment electricity and failure code meeting Alternation Display, alternately delay time is 2 seconds.
Relative to scheme of the prior art, advantage of the present invention is:
Combined type intelligent instrument described in the invention, by micro controller system and peripheral circuit thereof, achieve electric power detection display, hour meter and the function of malfunction coefficient, a table realizes multilist function, cost of manufacture is effectively reduced, saves installing space simultaneously
.
