Door action module 5 and alarm module 6 connect respectively.Wherein control module 4 includes early warning degree identification 41 and burst early warning is known
Other 42 two modules, emergency situations can effectively be identified by two kinds of modules and make for early warning act.
As shown in Fig. 2, Fig. 2 is the layout drawing of sensor of the invention, switch and alarming device, wherein sensor assembly 1
Including the vehicle speed sensor 111 installed in wheel portion 11；Installed in rearview mirror part 12 lateral distance sensor 121 and
Lateral infrared velocity sensor 122；Car door opening amplitude sensor 134 and infrared human body sensor installed in car door part 13
135；The infrared velocity sensor 144 of fore-and-aft distance sensor 143 and longitudinal direction installed in taillight part 14；Car door action module 5
Including the reversion switch 131 and lockup switch 132 installed in car door part 13；Alarm module 6 includes being installed on car door part 13
Buzzer 133 and taillight part 14 warning lamp 141, alarm 142.
As shown in figure 3, when automobile stops when driving, vehicle speed sensor 111 gathers speed sensor signal, when reading car
When speed is 0, controllable switch closure, start and stop module 3 starts early warning system.
Control module 4 reads rearview mirror part 12, car door part 13, the sensing data of taillight part 14.
When sensor is not detected by automobile side and rear has pedestrian or object proximity, car door is normally-open；Sensor is examined
When measuring automobile side has pedestrian or object proximity, sensor according to the distance of detection and the time to approach of velocity estimated object,
When the time being more than set threshold value, judge into next step, when the time being less than set threshold value, lockup switch 132
Locking, car door can not be opened；When sensor detects that there are pedestrian or object proximity in automobile rear, sensor is according to the distance of detection
And the time of velocity estimated object proximity, when the time being more than set threshold value, warning lamp 141 is opened, and warns rear pedestrian,
Car door is normally-open, when the time being less than set threshold value, the lateral distance of sensor judgment object and car door, and control module
4 judge the corresponding amplitude of car door opening.
When car door opening certain amplitude, when sensor receives emergency case, infrared human body sensor 135 starts work
Make；When sensor detects that occupant is introduced into car door region, buzzer 133 starts to alarm, and reversion switch 131 closes,
Make car door quick closedown；When sensor detects that occupant enters car door region, buzzer 133 is alarmed, and car door delays
Speed is closed, and alarm 142 is opened.
Specifically implementation process is：
Signal is reached control module 4 by vehicle speed sensor 111, and after control module 4 receives signal, control start and stop module 3 starts
Car door early warning system, when lateral distance sensor 121 and lateral infrared velocity sensor 122 have not received pedestrian either
When carrying out the signal of car, the infrared velocity sensor 144 of fore-and-aft distance sensor 143 and longitudinal direction of taillight part is started to work, when
Lateral distance sensor 121 and lateral infrared velocity sensor 122 receive pedestrian when either carrying out the signal of car, sensing
Data are reached control module 4 by device, and control module judges pedestrian or comes the car close time, are more than set threshold value when the time
When, the infrared velocity sensor 144 of fore-and-aft distance sensor 143 and longitudinal direction of taillight part 14 is started to work, and is less than when the time
During set threshold value, 132 locking of lockup switch, car door can not be opened.
There is row when the fore-and-aft distance sensor 143 of taillight part 14 perceives rear with the infrared velocity sensor 144 in longitudinal direction
People or when carrying out car, data are reached control module 4 by sensor, and control module 4 judges the pedestrian at rear or comes the car close time,
When the time being more than set threshold value, the warning lamp 141 of taillight part 14 is opened, and rear is warned, while allow car
Door is opened, and when the time being less than set threshold value, lateral distance sensor 121 judges pedestrian or carrys out the lateral distance of car, sentences
Data are reached control module 4 by the amplitude of disconnected car door opening, car door opening amplitude sensor 134, and control module 4 monitors in real time.
When car door opening, burst early warning identifies that 42 modules are started to work, and when rear has suddenly, object is swarmed into or pedestrian comes
The speed suddenly change of car constantly, start to work by infrared human body sensor 135, when sensor detects that occupant is introduced into car
During door region, buzzer 133 is alarmed, and reversion switch 131 closes, and car door is closed with fast speed, when occupant has been enter into
It is support personnel's safety during car door region, buzzer 133 alarms, and reversion switch 131 closes, with less speed closed door,
Alarm 142 is opened at the same time, reminds rear.
