Description
Technical field
The utility model relates to a kind of vehicle overspeed alarming device, belongs to the car electrics field.
Background technology
In recent years, along with the develop rapidly of modern automobile control technology and express highway, in countries in the world, no matter be transit industry or individual, automobile has all become the main vehicle of long-distance transportation.But the thing followed is the traffic accident incidence that raises day by day.Hypervelocity or speed-limit device also are not installed on present domestic most of automobile.When running at high speed for a long time on express highway, chaufeur is handled acceleration pedal for a long time and be can not get activity, causes fatigue easily.The phenomenon that exceeds the speed limit always occurs in the speed limit highway section, other people are caused potential safety hazard with themselves.Therefore the raising of automotive interior facility is conducive to promote the prosperity and development of automobile cause can ensure occupant's life security again.
Summary of the invention
A kind of vehicle overspeed alarming device comprises 89C51 micro controller system, data memory, speed sensor, keyboard, loudspeaker, warning flashing lamp, LED LCDs, also comprises control ECU.Described 89C51 micro controller system is mainly finished control and some calculation functions of peripheral hardware, described data memory is connected with the 89C51 micro controller system, the mouth of described speed sensor is connected with the 89C51 micro controller system, described keyboard is connected with the 89C51 micro controller system, described loudspeaker are connected with the 89C51 micro controller system respectively with reporting to the police, described LED LCDs input end is connected with the 89C51 micro controller system, and described 89C51 micro controller system is connected with engine air throttle by control ECU.
The utility model is the advantage of prior art relatively:
1, the utility model is simple in structure, convenient and practical, can come the maximum travel speed of restricting vehicle by artificial input automobile driving speed value.
2, the utility model utilizes micro controller system to send signal to control ECU, and then the automatically controlled engine throttle opening, ensures occupant's life security to the full extent.
3, the utility model adopts micro controller system, and LED Liquid Crystal Display (LCD) and data memory are conducive to automobile and develop to complete electronic age.
Description of drawings
Fig. 1 is the layout scheme drawing of a kind of vehicle overspeed alarming device of the utility model.
The specific embodiment
The 1-speed sensor; The 2-keyboard; The 3-89C51 micro controller system; The 4-data memory; The 5-LED LCDs; The 6-loudspeaker; 7-warning flashing lamp; 8-controls ECU; The 9-engine air throttle.
Below in conjunction with concrete drawings and Examples the utility model is described further.
As shown in Figure 1, a kind of vehicle overspeed alarming device of the utility model comprises speed sensor 1, keyboard 2,89C51 micro controller system 3, data memory 4, LED LCDs 5, loudspeaker 6, warning flashing lamp 7, control ECU8, engine air throttle 9.The speed signal that described keyboard will manually be imported passes to 89C51 micro controller system 3, and the speed signal that 89C51 micro controller system 3 will manually be imported stores in the data memory 4.Described speed sensor 1 passes to 89C51 micro controller system 3 with the automobile driving speed signal, and 89C51 micro controller system 3 changes into digital signal with the automobile driving speed signal through A/D, utilizes LED Liquid Crystal Display (LCD) 5 to demonstrate information such as moving velocity.The speed signal value that surpasses artificial input when the automobile driving speed value, and the occupant does not take under the situation of certain measure, the aperture that 89C51 micro controller system 3 is regulated engine air throttle 9 automatically by control ECU8, reduce the speed of a motor vehicle, and send chimes of doom and warning light is reminded the occupant by loudspeaker 6 and warning flashing lamp 7.
