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 to Figure 3, a kind of prior-warning device that prevents that arrangements for automotive doors from opening affects other vehicle pass-throughs comprises radar, pressure sensor, micro controller system 11, early warning panel 17 and central controlled lock 18, wherein:
Described radar comprises the left front monitoring radar 1 that is installed in the left front lamp of automobile, is installed in the right front monitoring radar 2 of Automobile Right headlight, is installed in the left back monitoring radar 3 and the right back monitoring radar 4 that is installed in the Automobile Right back light of automobile left rear light;
Described pressure sensor comprises the left front vehicle door handle pressure sensor 5 that is installed in handle place in the left front car door of automobile, be installed in the right front vehicle door handle pressure sensor 6 at handle place in the Automobile Right driver door, be installed in the left back vehicle door handle pressure sensor 7 and the right back vehicle door handle pressure sensor 8 that is installed in handle place in the Automobile Right tail gate at handle place in the left back car door of automobile;
Described early warning panel 17 is installed on the automobile instrument panel, and left front alert warning light 12, right front warning light 13, left back warning light 14 and right back warning light 15 and buzzer phone 16 are installed on the early warning panel 17;
Left front monitoring radar 1, right front monitoring radar 2, left back monitoring radar 3 links to each other by the input end of A/D converter 10 with micro controller system 11 respectively with right back monitoring radar 4, left front vehicle door handle pressure sensor 5, right front vehicle door handle pressure sensor 6, left back vehicle door handle pressure sensor 7 links to each other with op amp 9 respectively with right back vehicle door handle pressure sensor 8, each op amp 9 links to each other with the input end of micro controller system 11 by A/D converter 10 respectively, and the mouth of micro controller system 11 is connected with respectively left front warning light 12, right front warning light 13, left back warning light 14, right back warning light 15, buzzer phone 16 and central controlled lock 18.
Left front monitoring radar 1, right front monitoring radar 2, left back monitoring radar 3 and right back monitoring radar 4 all adopt narrow ripple radar.As shown in Figure 4, narrow ripple radar velocity measurement, its principle of work is that the moving target reflex time that the high-frequency signal of radar emission is radiated in its sphere of action changes frequency values (Doppler effect), this Doppler frequency shift is proportional to the speed of moving target.The principal particulars of narrow ripple radar is narrow radiation pattern, guarantees narrow search coverage.Monitored target vehicle enters after the narrow search coverage, and radar sends energizing signal.When monitored target vehicle left search coverage, this radar meter can confirm that target vehicle has left search coverage, and sent the speed of target carriage.Narrow ripple radar is because himself emission field angle is very narrow, and the useful range of radar only is limited to a track, and compared with common wide ripple radar, actv. has avoided the car speed in other tracks to disturb.Therefore, have particularity, optimal selection that to exempt from interfering narrow ripple radar be this device.The effect of above-mentioned four radars provide with this car adjacent lane on the moving velocity of vehicle, and whether affect the foundation of other vehicle pass-throughs as judging that door opening is got off.
Left front vehicle door handle pressure sensor 5, right front vehicle door handle pressure sensor 6, left back vehicle door handle pressure sensor 7 and right back vehicle door handle pressure sensor 8 all adopt piezoresistive pressure sensor.This pressure sensor has extremely low price and higher precision and constant characteristic preferably.Resistance strain gage is one of chief component of piezoresistive pressure sensor, and resistance strain gage is a kind of Sensitive Apparatus that strain variation on the measured piece is converted into a kind of electric signal.Strain-gauge is bonded in closely by special bonding agent and produces on the mechanics strain matrix, and when the stressed generation STRESS VARIATION of matrix, resistance strain gage also produces deformation together, and the resistance of strain-gauge is changed, and is added in ohmically voltage and changes thereby make.
Op amp 9 adopts LM324.LM324 be independently, the compensation of high gain, internal frequency, with the op amp of differential input; compare with the standard operation amplifier of single supply application scenario; can be operated in low to 3.0 volts or high under 32 volts power supply; common-mode input range comprises negative supply; thereby eliminated in many application scenarios the essentiality that adopts the external bias element; and has short-circuit protection output, the pin arrangements of industry standard.
Central controlled lock 18 adopts electric door lock mechanism, and as shown in Figure 5, this electric door lock mechanism mainly includes door switch, gate lock actuator and door lock controller.Door switch is comprised of main supply switch and switch-dividing, and main supply switch is contained in chaufeur by the side of on the car door, and the pilot control main supply switch can pin all car doors of full car or open, and switch-dividing is contained on other each car doors, can control separately a car door; Gate lock actuator is for carrying out instruction, electromagnetic type, DC motor type, permanent magnet motor formula being arranged, and all is to change locking and the unlatching that its sense of motion is carried out the action realization door lock of locking a door or open the door by changing polarity.Door lock controller is the control setup that locking and unbalanced pulse electric current are provided for gate lock actuator.The maximum characteristics of using central controlled lock control door lock are to have a central controlled device, and various switching value signals are controlled the both positive and negative polarity of output signal, thereby reached the purpose that each door-lock motor rotates and reverse as energizing signal.
Working process of the present utility model is as described below:
The purpose of this utility model is to monitor other vehicles around this car, and the occupant is carried out early warning and the car door under danger signal is closed by force.When left front monitoring radar 1, right front monitoring radar 2, left back monitoring radar 3, right back monitoring radar 4 monitor certain direction and have other vehicle high-speed to sail to come, radar transmits electromagnetic signal to A/D converter 10, A/D converter 10 is converted to digital signal input micro controller system 11 with electromagnetic signal, micro controller system 11 analytic signals, when signal reaches danger signal, the warning light of micro controller system 11 control respective direction lights, and the occupant is carried out the early warning first time; If the occupant ignores early warning, any one Door Handle that spurs the side of sending a car is prepared to get off, be installed in the pressure sensor work at handle place in the corresponding car door, signal is passed to op amp 9, op amp 9 amplifies signal passes to A/D converter 10 again, A/D converter 10 is converted to digital signal input micro controller system 11 with electromagnetic signal, micro controller system 11 analytic signals, control buzzer phone 16 gives the alarm, the occupant is carried out the early warning second time, micro controller system 11 sends signal to central controlled lock 18 simultaneously, central controlled lock is carried out Door Lock motor commutation output control, finish block action, stop the occupant to open car door, trying to avert accidents affects other vehicle pass-throughs; If radar monitoring is to danger signal, warning light work, but the occupant does not get off behavior then pressure sensor do not work, buzzer phone 16 does not give the alarm yet, and has reduced the impact of caution sound on the people, the traveling comfort when having improved by bus.
