Technical field

The utility model relates to a kind of auto meter dish, particularly a kind of motor bike Multifunctional LED digital instrument dial plate.

Background technology

The auto meter dish adopts mechanical pointer to show more at present, its signal is gathered by mechanical drive gear, because its total system is a mechanical device, so low, poor reliability of precision, even so, motorcycle driving is its total time that travels, the speed of a motor vehicle, engine speed, the total kilometrage that travels, travel time mileage, temperature, oil consumption constantly, data such as Battery voltage all not all show at a gauge panel, in case low on fuel, Battery voltage are low excessively, the speed of a motor vehicle can not give the user with prompting too soon.

Summary of the invention

The purpose of this utility model is exactly the defective that exists at prior art, when being provided, a kind of vehicle ' can show the total time that travels, the speed of a motor vehicle, engine speed, the total kilometrage that travels, the total kilometrage that travels, temperature, oil consumption, Battery voltage, work as low on fuel, Battery voltage is low excessively, can alarm when the speed of a motor vehicle is too fast, the Multifunctional LED numeral motorcycle instrument dish of precision height, good reliability.

The purpose of this utility model is to realize like this, a kind of motorcycle instrument dish, comprise microprocessor, car speed sensor, engine speed sensor, fuel-quantity transducer, the Battery voltage sensor, temperature sensor, the advance signal treatment circuit, be provided with the charactron display circuit in addition, A/D change-over circuit and external storage read/write circuit and LED indicating circuit and keyboard input circuit, the mouth of advance signal treatment circuit, the mouth of the mouth of A/D change-over circuit and keyboard input circuit is connected with the input end of microprocessor, and the input end of the input end of charactron display circuit and LED indicating circuit is connected with the mouth of microprocessor.The signal of being sent here by car speed sensor, driving engine speed transmission sensor is through the advance signal treatment circuit, the voltage signal that temperature, oil mass, voltage sensor are sent here is handled through the A/D change-over circuit, each road signal is become the receptible digital signal input microprocessor of micro controller system, carry out exporting to the charactron display circuit behind the data handing and the LED indicating circuit shows, indicates, show and indicate which kind of data to select or roll display by the keyboard input circuit.If data normally warning circuit do not work, otherwise corresponding light-emitting diode sends flicker indication and reports to the police in the LED indicating circuit.

The motorcycle instrument dish that adopts the utility model to provide, when vehicle ', can show the total time that travels, the speed of a motor vehicle, engine speed, the total kilometrage that travels, time mileage of travelling, temperature, oil consumption, Battery voltage, in case can report to the police when surpassing limit value, monitoring accuracy height, good reliability.
