Abstract
The utility model discloses an anti-rollover early warning device for automobiles. The anti-rollover early warning device for the automobiles comprises an acceleration sensor, a speed sensor, a singlechip microcomputer, a warning light and a buzzer, wherein the acceleration sensor, the speed sensor, the warning light and the buzzer are respectively connected with the singlechip microcomputer. According to the anti-rollover early warning device for the automobiles disclosed by the utility model, through performing real-time monitoring on the acceleration and speed information of the automobiles, warning and prevention can be performed on vehicle rollover accident potentials on the way of driving, and therefore, the active safety of vehicles is enhanced, and the rollover accident is effectively prevented from occurring. The anti-rollover early warning device for the automobiles is simple in structure and economic and practical, and is suitable for being widely applied to various automotive vehicles.
Description
Technical field
The utility model belongs to vehicle active safety field, is specifically related to a kind of car for guarding against side turned over prior-warning device.
Background technology
Along with the fast development of transportation, driving safety also receives increasing concern.In the car accedent statistics, the hazard rating of rollover accident is only second to collision case, and the personnel that it causes and property damage are also very big.The reason that causes the vehicle rollover accident has two kinds, and a kind of is because the obstacle lateral impact on vehicle and the road surface " trips " rollover that trips that causes with it; The excessive rollover that causes of transverse acceleration when another kind is curvilinear motion.Preceding a kind of reason is because extraneous uncertain factor is caused, is difficult to avoid in advance; Then a kind of is owing to the reason of vehicle self is caused, can prevent in the scope.At present, traditional rollover sensor is based on gyroscope and makes, and system's very complicated is difficult to popularize.
Summary of the invention
At defective and deficiency that prior art exists, the purpose of this utility model is, a kind of car for guarding against side turned over prior-warning device is provided.
In order to realize above-mentioned task, the utility model is taked following technical solution:
A kind of car for guarding against side turned over prior-warning device comprises acceleration pick-up, speed sensor, micro controller system, Warning light and buzzer phone, and wherein, acceleration pick-up, speed sensor, Warning light and buzzer phone are connected with micro controller system respectively.
Described acceleration pick-up adopts MMA7260QT type triple axle acceleration pick-up.
Described speed sensor adopts contactless ZLS-Px type sensor.
Described micro controller system adopts Freescale S12X model micro controller system.
Described Warning light adopts the LED lamp.
The utility model can be warned and be prevented the vehicle rollover accident potential of driving in the way by the real-time monitoring to vehicle acceleration and velocity information, thereby has improved the active safety of vehicle, has effectively prevented the generation of rollover accident.This apparatus structure is simple, and is economical and practical, and all kinds of self-propelled vehiclees suit to be widely used in.
Description of drawings
Fig. 1 is annexation scheme drawing of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.
The specific embodiment
A kind of car for guarding against side turned over prior-warning device based on technical solutions of the utility model, as shown in Figure 1, comprise acceleration pick-up, speed sensor, micro controller system, Warning light and buzzer phone, wherein, acceleration pick-up, speed sensor, Warning light and buzzer phone are connected with micro controller system respectively.Described acceleration pick-up adopts MMA7260QT type triple axle acceleration pick-up, described speed sensor adopts contactless ZLS-Px type sensor, described micro controller system adopts Freescale S12X model micro controller system, described Warning light adopts the LED lamp, and wherein the LED lamp comprises red and yellow two kinds of color LED lamps.
Acceleration pick-up is installed in the vehicle chassis place, but the lateral acceleration information of real-time detection vehicle, and this information passed to micro controller system; Speed sensor is installed on the output shaft next door of change-speed box, but the velocity information of real-time detection vehicle, and this information also passed to micro controller system simultaneously.Warning light is installed in the gauge panel, comprises the LED lamp of red, yellow two kinds of colors; Buzzer phone is installed in the operator's compartment, can send two kinds of aud. snl.s of low frequency and high frequency.
In micro controller system, there is the criticality safety acceleration rate threshold that automobile prevents from turning on one's side and takes place under different speed of a motor vehicle conditions.In the vehicle driving process, the acceleration information of acceleration pick-up real-time detection vehicle also passes to micro controller system with this information; The velocity information of speed sensor real-time detection vehicle is also also passed to micro controller system with this information.Micro controller system is compared the acceleration/accel secure threshold according to the acceleration/accel and the velocity information that receive, the lateral acceleration information that judgement records and the relation between the acceleration/accel secure threshold.If the acceleration information that records approaches but does not reach the acceleration/accel secure threshold of automobile under this velocity conditions, micro controller system just can send instruction to Warning light and buzzer phone, yellow led lantern festival in the Warning light lights and glimmers at this moment, buzzer phone sends the low frequency buzzerphone, reminds steerman to adjust vehicle running state and prevents rollover; If the acceleration information that records reaches and surpass the acceleration/accel secure threshold of automobile under this velocity conditions, micro controller system just can send instruction to Warning light and buzzer phone, this moment, the red LED lantern festival in the Warning light lighted and with high frequency flicker, buzzer phone sends the high frequency buzzerphone, caution steerman automobile storage should be revised vehicle running state rapidly in serious rollover danger.
Used electronic devices and components are commercially available known product in the device of the present utility model, and those skilled in the art can realize the connection of each electronic devices and components according to the technical solution of the utility model.
