Abstract

The utility model discloses an automobile steering wheel rotating angle position display device based on a singlechip, and the automobile steering wheel rotating angle position display device based on the singlechip includes a coded disc, the singlechip and a liquid crystal display, wherein the coded disc is connected with the input end of the singlechip, and the output end of the singlechip is connected with the liquid crystal display. The coded disc adopts an optical-electricity encoder for coding a disc. The number of the singlechip is AT89C52. An existing steering wheel rotating angle sensor is mainly used for detecting the rotating angle of the steering wheel and the rotating speed to determine the size of power-assisted steering, except a function of safety prompt to a driver. Precision demands of the device are commonly high, so that the price is expensive. and the automobile steering wheel rotating angle position display device based on the singlechip is used for a safety prompt, and does not need such a high precision, so that a coded disc device is chosen, the cost is reduced, and the purpose of the automobile steering wheel rotating angle position display device based on the singlechip can be achieved very well.

Description

A kind of SCM Based corner of vehicle steering wheel lever position indicator
Technical field
The utility model belongs to the safe driving of vehicle field, relates to a kind of SCM Based corner of vehicle steering wheel lever position indicator.
Background technology
Bearing circle is to control the very important a kind of device of motor turning, when needs turn to, bearing circle can be controlled deflector and control turning to of front-wheel, some chaufeurs of now, careful some chaufeurs, often forget with steering wheel return just after flame-out getting off just, and do not notice that own automobile is not also just returning when getting on the bus, with regard to the driving of lighting a fire yet.Yet the fast development along with China's economy, the particularly fast development of auto trade, make the people who nowadays has automobile more and more, thereby cause the place that parks cars more and more limited, to such an extent as to the parking gap between automobile and automobile is fewer and feweri, if not returning, bearing circle just just directly do not play walking vehicle, and chaufeur is not known in advance, the probability that will make the automobile of driving directly bump against front vehicles increases greatly, new hand particularly, if do not form a good custom, the probability that this accident occurs will be larger.
Thereby, in order to allow chaufeur just know before driving whether the own vehicle steering of driving is just returning, avoid bumping against with front vehicles, reminding driver is correctly driven a vehicle, the read out instrument of a kind of SCM Based corner of vehicle steering wheel position has been installed on the bearing circle of automobile, this device can be according to the angle of rotating of steering wheel, shows in real time direction and the general proportions of current bearing circle institute rotational angle.Because the required power supply of micro controller system is 5V, therefore this device can not need the automotive battery power supply, directly power supply is installed to the inside of bearing circle, if own institute drives a car bearing circle inside provided when other electrical equipments of loading 5V power supply that power supply just can be installed, directly connect the power supply after the storage battery step-down, the demonstration situation of chaufeur by this device, position that just can clear own bearing circle of the moment.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is, provides a kind of the corner of vehicle steering wheel lever position indicator of safety control can be provided for chaufeur.
In order to realize above-mentioned task, the utility model adopts following technical scheme to be achieved:
A kind of SCM Based corner of vehicle steering wheel lever position indicator comprises code-disc, micro controller system and Liquid Crystal Display, and the input end of code-disc and micro controller system is connected, and the mouth of micro controller system is connected with Liquid Crystal Display.
The utility model also has following technical characterstic:
Described code-disc adopts the photoelectric encoder code-disc.
Described micro controller system adopts the AT89C52 micro controller system.
The utility model compared with prior art has following advantage:
Existing steering wheel angle sensor is mainly used to detect corner and the velocity of rotation of bearing circle, determine the size of power steering, and chaufeur is not had the safety instruction purposes, general this device accuracy rate is had relatively high expectations, thereby price comparison is expensive, and the utility model is used for safety instruction and uses, do not need so high precision, therefore select code disc device, reduced cost of price, and can also well reach the purpose of this utility model.
Description of drawings
Fig. 1 is the utility model annexation schematic diagram.
Below in conjunction with drawings and Examples, particular content of the present utility model is described in more detail.
The specific embodiment
Below provide specific embodiment of the utility model, need to prove that the utility model is not limited to following specific embodiment, all equivalents of doing on present techniques scheme basis all fall into protection domain of the present utility model.
Defer to technique scheme, as shown in Figure 1, a kind of SCM Based corner of vehicle steering wheel lever position indicator comprises code-disc, micro controller system and Liquid Crystal Display, and the input end of code-disc and micro controller system is connected, and the mouth of micro controller system is connected with Liquid Crystal Display.
Described code-disc adopts the photoelectric encoder code-disc, is arranged on the wheel steering tubing string, adopts photoelectric effect, and it can export corresponding square wave to micro controller system thereupon when rotating of steering wheel.In the code-disc installation process, need to code-disc is coaxial with the vanning steering handwheel, and will guarantee that photoelectric detection system can be vertically over against grating disc, the information that detects of guarantee is accurate like this.
Described micro controller system adopts the AT89C52 micro controller system, and this micro controller system has 32 I/O mouths, can be used for interrupting and timing and serial communication use.
Described LCD types is 12864, and it is 128 row, and 64 row are arranged on vehicle steering.
The utility model when work, at first the utility model is carried out initialization, be mainly that micro controller system and liquid crystal device are carried out initialization, Liquid Crystal Display carries out initialization and comprises setting to display position, and the number of pages setting, shows that here number of pages is set to two pages.then after the pulse count record that micro controller system is exported the photoelectric detection system of code-disc, and then control the liquid crystal device by its I/O pin, pulse count is shown on the liquid crystal device in proportion, in the process that shows, with two pages of Liquid Crystal Display come the display automobile bearing circle toward left steering and right-hand turning to, in addition when the steering wheel angle position with return the positive position deviation angle when excessive, if the backlight that starts the liquid crystal device is more or less the same does not start, here we are set as 5 pulse counts with reference to the drift angle, so just can avoid departing from when not being clearly and waste power consumption, and reminding driver that can be more eye-catching when having powerful connections lamp is grasped the particular location of bearing circle, correct steering vehicle, the generation that avoids traffic accident.
