The speedometer of described a kind of light belt scanning display speed is provided with L1-L13 totally 13 banded luminescence units on index dial, banded luminescence unit is banded luminophor of EL or the banded luminophor of LED.
The speedometer of described a kind of light belt scanning display speed, its one-chip computer digital processing circuit are by chip IC 1, IC2, and capacitor C 1, C2, crystal oscillator JZ form; Its sequencing circuit is made up of the resistance R 3-R15 that connects with 8,9,11 to 19 pin of chip IC 2; Its luminous output circuit is made up of the electronic switch BG2-BG14 that connects with resistance R 3 one R15 of sequencing circuit; Its light emission drive circuit is by capacitor C 3, C4, and resistance R 1, R2, electronic switch BG1, transformer B form.
The vehicle wheel rotational speed signal enters the one-chip computer digital processing circuit through speed of a motor vehicle Hall element and handles, treated signal enters sequencing circuit, luminous output circuit, press the height of tach signal, open corresponding electronic switch, make the light emission drive circuit signal that enters electronic switch light banded luminescence unit on the index dial, make the height of luminescence unit, show the speed of a motor vehicle with scan mode and the synchronous forward or reverse of gauge pointer according to tach signal.
The utility model compared with prior art has the following advantages: its intuitive is strong, can make the personnel of driving can see the speed that gauge pointer is indicated soon clearly, in time judges, adjusts the transport condition of vehicle, reduces traffic hazard; Show Vehicle Speed with scan mode, improved the class of high-grade motor vehicle speed sheet lighting, making it has increased the surcharge of high-grade motor vehicle with modern novel high-tech breath.
