Fig. 2 is the method flow schematic diagram that the embodiment of the present invention is carried out early warning;
Fig. 3 is the method flow schematic diagram of embodiment of the present invention car door opening early warning.
The specific embodiment
The embodiment of the present invention after car door being detected and need to opening, one of the car door place projection of opening at the needs virtual car door in opening.Owing to adopting the virtual car door mode of projection to carry out early warning, thereby can not be affected in noisy environment yet; Further owing to adopting vision alarm mode, thus more directly perceived
The position size of virtual car door can be determined according to car door position and size.Preferably, in order to guarantee near the visual effect of rear view of vehicle pedestrian and vehicle early warning especially vehicle, the size of virtual car door can be more bigger than actual car door, the position of virtual car door and state can be position and the states that car door is opened completely, can virtual car door (being screen) be also vertical with vehicle body.
Below in conjunction with Figure of description, the embodiment of the present invention is described in further detail.
As shown in Figure 1, the forewarn system of the embodiment of the present invention comprises: at least one car door sensor 10 and virtual display 20
Whether car door sensor 10, need to open for detection of car door;
In force, car door sensor 10 can be arranged on the handle for opening door of car door inside.Wherein, on a handles, there is a car door sensor 10.Can select as required to arrange on those handles car door sensor 10.
Each car door sensor 10 can detect the pressure of car door in real time, and the threshold value of pressure and setting is compared, if car door pressure detected, reaches setting threshold, determines that car door needs to open.
Preferably, embodiment of the present invention virtual display 20 comprises: air screen unit 210 and projecting cell 220;
Projecting cell 220, for after car door being detected at car door sensor 10 and need to opening, projects to a virtual car door in opening on plane fog screen.
Concrete, air screen unit 210 adopts the concussion of electronics overclocking, by the high-frequency resonant of transducer, dried up of water throwing is produced to water smoke, in conjunction with aerodynamic principle, produce plane fog screen again, projecting cell 220 can form virtual image above picture is incident upon.
This virtual image is the image of car door opening, can produce to vehicle below early warning effect intuitively, and the tighter vehicle that has little time reaction for following, can not cause damage through air screen.
In force, the image of this door opening state can directly be stored in projecting cell 220, also can be stored in plug and play in other movable storage device.Virtual display 20 can be installed according to the concrete feature of vehicle, and for example air screen unit 210 can be arranged on roof, and projecting cell 220 can be arranged on rear car mirror side.
In force, threshold value can be set as required.
Preferably, the forewarn system of the embodiment of the present invention can further include: car speed sensor 30.
Whether static car speed sensor 30, for after car door being detected at car door sensor and need to opening, detect vehicle;
Accordingly, virtual display 20 specifically for:
At sensor, car door being detected needs to open, and car speed sensor detects after stationary vehicle, one of the car door place projection of opening at the needs virtual car door in opening.
Wherein, car speed sensor 30 can be determined by vehicle GPS the speed of vehicle; Also can a built-in GPS module in car speed sensor 30; Car speed sensor 30 can also be determined by the speed meter of vehicle the speed of vehicle.
Preferably, the forewarn system of the embodiment of the present invention can further include: position transduser 40.
Whether position transduser 40, for after car door being detected at car door sensor 10 and need to opening, detect vehicle in prohibition parking area;
Accordingly, virtual display 20 specifically for:
At car door sensor 10, car door being detected needs to open, and car speed sensor 30 detects stationary vehicle, and position transduser inspection 40 measures vehicle behind non-prohibition parking area, one of the car door place projection of opening at the needs virtual car door in opening.
In force, if position transduser 40 detects vehicle behind prohibition parking area, notify passengers inside the car's vehicle in prohibition parking area, and judge whether passengers inside the car need to continue opening car door;
Accordingly, virtual display 20 detects car door at car door sensor 10 to be needed to open, and car speed sensor 30 detects stationary vehicle, and position transduser 40 detects vehicle in prohibition parking area but need to continue after opening car door, one of the car door place projection of opening at the needs virtual car door in opening.
Wherein, position transduser 40 detects car door at car door sensor 10 to be needed to open, and vehicle detected and behind prohibition parking area, can adopt the modes such as word, sound, image to notify passengers inside the car's vehicle in prohibition parking area.When judging whether to continue opening car door, can inquire whether passengers inside the car continue opening car door by modes such as image, sound, and judge whether to continue opening car door, judgment mode has a variety of, such as judging by button, if passengers inside the car press specified button, represent to continue opening car door, this button can be that mechanical type can be also the button of touch-screen; Can also judge by sound, passengers inside the car represent whether need to continue opening car door by sound.
In force, between car door sensor 10, virtual display 20, car speed sensor 30 and position transduser 40, can connect by short-distance wireless communication mode, include but not limited to Zigbee, bluetooth etc.
Preferably, car door sensor 10, virtual display 20, car speed sensor 30 and position transduser 40 can be distinguished a built-in network sensor.
Wherein, need altogether 8 network sensors: two network sensors are positioned on 4 car door sensors, two network sensors lay respectively on the air screen unit 210 and projecting cell 220 in virtual display 20, and also having two node of network is respectively on car speed sensor 30 and position transduser 40.Between network sensor, adopt short-distance wireless communication technology to carry out alternately.It should be noted that, 8 network sensors form a sensor network, and concrete network topology can be set as required.
In force, after car door opening, in virtual display 20, projecting cell 210 and air screen unit 220 are closed.
Based on same inventive concept, a kind of method of carrying out early warning is also provided in the embodiment of the present invention, because the principle that the method is dealt with problems is similar to embodiment of the present invention forewarn system, so the enforcement of the method can, referring to the enforcement of forewarn system, repeat part and repeat no more.
As shown in Figure 2, the method that the embodiment of the present invention is carried out early warning comprises the following steps:
Whether step 201, detection car door need to open;
Preferably, in step 201, after car door pressure arrival setting threshold being detected, determine that car door needs to open.
Preferably, in step 202, one of the car door place projection of opening at the needs virtual car door in opening, comprising:
After car door sensor detects car door and need to open, by high-frequency resonant, the car door place of opening at needs forms plane fog screen;
A virtual car door in opening is projected on plane fog screen.
Preferably, in step 202, detecting after car door need to open, can also detect vehicle and whether remain static; If vehicle detected, remain static, one of the car door place projection of opening at the needs virtual car door in opening.
Preferably, in step 202, car door detecting after need to open, and after definite vehicle remains static, can also detect vehicle whether in vehicle in non-prohibition parking area, if vehicle detected in non-prohibition parking area, one of the car door place projection of opening at the needs virtual car door in opening.
