Specific embodiment
The embodiment of the present invention is further described below in conjunction with attached drawing.
A kind of on-vehicle navigation apparatus based on infrared ray and ultrasonic wave, as shown in Figures 1 and 2, including power supply, Arduino
Processor, infrared distance measurement module, ultrasound measurement module, PM2.5 sensor, warning module, human-computer interaction module and Image Acquisition
Module；The Arduino processor and infrared distance measurement module, ultrasound measurement module, PM2.5 sensor, warning module, it is man-machine mutually
Dynamic model block, image capture module are connected, the power supply and Arduino development board, infrared distance measurement module, ultrasound measurement module,
PM2.5 sensor, warning module, human-computer interaction module, image capture module and automobile TT motor be connected and electricity be provided
Energy.
The infrared distance measurement module, ultrasound measurement module are the sensor module of two kinds of different rangings, are responsible for vehicle of adjusting the distance
The a certain range of barrier of body carries out ranging.Wherein, infrared distance measurement module uses infrared sensor, and ultrasound measurement module is adopted
With ultrasonic sensor, infrared sensor is selected for the ranging being closer, for selecting ultrasound apart from farther away ranging
Wave sensor.This system uses two distinct types of sensor, can be realized far and near alternately distance measurement function, and the result of measurement passes
Give Arduino processor.When " barrier " in front of car body is less than setting range apart from car body, Arduino processor is opened
Dynamic warning module work, effectively prompts to driver.
The PM2.5 sensor is used to detect PM2.5 concentration when haze weather, and testing result is sent at Arduino
Manage device.Arduino processor sends human-computer interaction module to after information processing and is shown, driver can be by man-machine
Interactive module is intuitive to see visibility to realize interaction.
Described image acquisition module is used to record the traffic information in front of car body using camera, records condition of road surface,
It is similar to traditional automobile data recorder, realize camera shooting acquisition function, so that it is suitable for the weather conditions such as dense fog, haze, night, for
The distance of distance chooses different sensors and carries out ranging, makes to measure more accurate.
The human-computer interaction module manually sets sense for driver using touch screen or display screen and key combination device
Know range and display function.When vehicle and barrier reach setting sensing range, Arduino processor passes through warning module
Prompt driver pays attention to avoiding.
When the warning module has barrier within the set range, driver is prompted in the form of alarm.At Arduino
When the distance that reason device is obtained by range finder module measurement is lower than setting range, Arduino processor is by warning module with sound
Or voice mode is alarmed.Warning module carries out acousto-optic early warning using buzzer and light emitting diode.
The Arduino processor is as information processing centre, primary recipient infrared distance measurement module and ultrasound measurement module
The front of the obstacle distance information of feedback, the PM2.5 concentration information of PM2.5 sensor feedback and image capture module acquisition
Traffic information is simultaneously handled, and control human-computer interaction module carries out information interaction, and control warning module realizes warning function: when driving
When having barrier in the range of the person's of sailing setting, warning module then starts to alarm, and realizes barrier prompt function.Arduino processing
Device simultaneously issues control information control TT motor running to TT motor, controls the traveling of vehicle.
Process flow of the invention is as shown in figure 3, firstly, Arduino processor carries out initialization process；Then, TT horse
It reaches, infrared distance measurement module, ultrasound measurement module, PM2.5 sensor carry out initialization process；Vehicle driving mistake is driven in TT motor
Cheng Zhong, when encountering barrier during car body advances, according to different distances, different sensors can respond immediately,
The distance between front obstacle to trolley is fed back into Arduino processor in real time, Arduino processor receive away from
It will compare with pre-determined distance from after information, be preset if barrier is less than at a distance from trolley, and pass through warning module for information
As a result (buzzer or light emitting diode) feeds back to driver in different forms.
The present invention does not address place and is suitable for the prior art.
It is emphasized that embodiment of the present invention be it is illustrative, without being restrictive, therefore packet of the present invention
Include and be not limited to embodiment described in specific embodiment, it is all by those skilled in the art according to the technique and scheme of the present invention
