Abstract
The utility model discloses a tire pressure monitoring device based on a wheel speed sensor. The tire pressure monitoring device comprises a wheel speed sensor, a conditioning circuit, a singlechip and an alarm unit, wherein the wheel speed sensor, the conditioning circuit, the singlechip and the alarm unit are sequentially connected. The tire pressure monitoring device disclosed by the utility model can acquire tire pressure information through the sensor and feed the information to a driver in real time, so that the driver can master the tire information in real time; in case of abnormity of the tire pressure, the device can emit an alarm signal to remind the driver of paying attention and adopting measures, so as to guarantee driving safety. And the device has the advantages of low input, good realtime performance, simple and easy implementation, convenience in maintenance and the like.
Description
Technical field
The utility model belongs to the vehicle safety technical field, relates in particular to a kind of tire pressure monitoring device based on wheel speed sensors.
Background technology
Tire is the important component part of automobile, and its performance directly has influence on the safety traffic of automobile and the personal safety of Che Nei.The annual traffic accident that causes by blowing out occupies very big proportion in all traffic accidents.In the running at high speed of automobile, tire fault is that all chaufeurs are worried and the most difficult prevention the most, also is the major cause that sudden traffic accident takes place.According to statistics, on the express highway at home, the traffic accident that causes accounts for 70% of total number of accident by blowing out.In the U.S., this ratio has caused serious threat for people's the person and property safety especially up to 80%.Therefore, the in-depth study system for monitoring pressure in tyre is monitored tire pressure in real time and is in time reported to the police to chaufeur when pressure abnormity, can make chaufeur grasp tire pressure at any time, greatly improves travel safety.
Summary of the invention
The purpose of this utility model is, proposes a kind of tire pressure monitoring device based on wheel speed sensors, and the variation of tire pressure made chaufeur grasp tire pressure at any time when this device passed through the monitoring running car, guaranteed traffic safety.
In order to realize above-mentioned task, the utility model takes following technical scheme to be solved:
A kind of tire pressure monitoring device based on wheel speed sensors comprises wheel speed sensors, modulate circuit, micro controller system and alarm unit, and wherein, wheel speed sensors, modulate circuit, micro controller system and alarm unit are connected successively.
The utility model also has following other technologies characteristics:
Described wheel speed sensors adopts the WH515027 sensor.
Described micro controller system adopts the MC9S12XS128 micro controller system.
Described alarm unit comprises LED lamp and buzzer phone.
The utility model obtains tire pressure information by sensor, and information is in time fed back to chaufeur, makes chaufeur can grasp tire information at any time, when tire pressure is unusual, device sends alerting signal, and the prompting chaufeur is noted and taken measures, guaranteed driving safety.This device have drop into low, real-time good, simple and easy to do, be convenient to advantage such as maintenance.
Description of drawings
Fig. 1 is annexation scheme drawing of the present utility model.
Fig. 2 is the circuit diagram of modulate circuit of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.
The specific embodiment
Defer to technique scheme, as shown in Figure 1, a kind of tire pressure monitoring device based on wheel speed sensors comprises wheel speed sensors, modulate circuit, micro controller system and alarm unit, wherein, wheel speed sensors, modulate circuit, micro controller system and alarm unit are connected successively.In this device, wheel speed sensors adopts the WH515027 sensor, is used for obtaining vehicle wheel rotational speed information; Modulate circuit adopts modulate circuit as shown in Figure 2, and the wheel speed signal that this circuit mainly obtains sensor amplifies and nurses one's health; Micro controller system adopts the MC9S12XS128 micro controller system, is used for signal data is handled and judged, and the information output of control alarm unit.
Can cause that when tire pressure changes tire radius changes, cause tire rotational speed variation in the identical time, so this device takes the mutual method relatively of interior number of tire revolutions of set time to judge whether tire pressure is normal.During running car, wheel speed sensors sends impulse singla, passes through modulate circuit, imports micro controller system into after signal is amplified, and by micro controller system signal is compared processing, thereby judge whether tire pressure is unusual, and the control alarm unit is handled accordingly.
Alarm unit comprises LED lamp and the buzzer phone of red greenish-yellow three kinds of colors in this device, the situation the when type of alarm that adopts light and sound to combine is pointed out abnormal tyre, and have only a LED lamp to be in illuminating state at one time.Tire pressure just often, green LED lamp is in illuminating state, buzzer phone does not give the alarm; When tire pressure was too small, yellow LED lamp was lighted, and buzzer phone sends chimes of doom simultaneously; When tire pressure was excessive, red LED lamp was lighted, and buzzer phone sends chimes of doom simultaneously.
The electronic devices and components that the utility model adopts are known product, and those skilled in the art are according to the i.e. concrete connection mode of electronic devices and components as can be known of the technical solution of the utility model.
