Abstract
A device for automatically reminding a passenger to buckle up comprises a power supply module, an automobile starting switch, a safety belt sensing switch, an ultrasonic distance measuring sensor, a single chip microcomputer and an alarm system, wherein the input end of the automobile starting switch is connected with the power supply module through wires, the output end of the automobile starting switch is connected with the safety belt sensing switch, the input end of the ultrasonic distance measuring sensor is connected with the output end of the safety belt sensing switch, the output end of the ultrasonic distance measuring sensor is connected with the input end of the single chip microcomputer, and the alarm system is connected with the output end of the single chip microcomputer. Whether the passenger sits on a seat or not is determined through an ultrasonic distance measuring method, and the device for automatically reminding the passenger to buckle up is installed in the center of the backrest of a passenger seat. The electronic automatic control is adopted, and the device for automatically reminding the passenger to buckle up is accurate in use, small in size, low in weight and capable of effectively eliminating potential safety hazards produced when the passenger does not buckle up.
Description
Technical field
The utility model relates to field of automobile safety, particularly a kind of automatic alarm passenger device of fastening the safety belt.
Background technology
Safety strap is the vitals of field of automobile safety.Because people's awareness of safety is not strong, the phenomenon of passenger's safety belt buckling free appears often, and this is a very large potential safety hazard.
Automobile safety belt reminding device of today generally is according to the passenger variation of the pressure of seat to be detected on the seat whether sat the passenger, but because people's sitting posture is different, is difficult to guarantee that the passenger touches pressure switch accurately, and this just causes the inaccuracy of this device work.Above-described problem has to be solved, and this just need to have a kind of new automatic alarm passenger device of fastening the safety belt, and the passenger is reminded.
Summary of the invention
The purpose of this utility model is to address the above problem, and providing behind a kind of automobile starting in time, reminding passengers fastens one's safety belt to guarantee the by bus device of personal security.Be achieved through the following technical solutions:
A kind of automatic alarm passenger device of fastening the safety belt, comprise power module, automobile starting switch, the safety strap inductive switch, ultrasonic distance-measuring sensor, micro controller system and warning, described automobile starting switch input end is connected with power module by wire, mouth is connected with the safety strap inductive switch, described ultrasonic distance-measuring sensor input end is connected with safety strap inductive switch mouth, mouth is connected with the micro controller system input end, described warning is connected with the micro controller system mouth, described safety strap inductive switch is the normally closed switch, be embedded in the safety strap slot, switch was not closure state when the safety strap plug inserted slot, when the safety strap plug inserts slot, plug ends is pressed the safety strap inductive switch opens it, this device adopts the mode of ultrasonic ranging to determine whether sat the passenger on the seat, is installed in passenger seat backrest middle position.
Advantage of the present utility model:
1, the utility model effectively reminding passengers in time fasten one's safety belt, effectively eliminated the potential safety hazard of passenger's safety belt buckling free.
2, the utility model adopts the mode of ultrasonic ranging to judge whether to sit the passenger, makes this device ratio of precision higher.
3, the utility model is simple in structure, be installed in take up room in the car little.
Description of drawings
Fig. 1 is the fasten the safety belt layout schematic diagram of device of a kind of automatic alarm passenger of the utility model.
The specific embodiment
The 1-power module; The 2-automobile starting switch; 3-safety strap inductive switch; The 4-ultrasonic distance-measuring sensor; The 5-micro controller system; The 6-warning; The 7-wire.
Below in conjunction with the embodiment accompanying drawing the utility model is described further.
The passenger of automatic alarm shown in the utility model device of fastening the safety belt comprises power module 1, automobile starting switch 2, safety strap inductive switch 3, ultrasonic distance-measuring sensor 4, micro controller system 5, warning 6 and wire 7 as shown in Figure 1.When car engine, described automobile starting switch 2 is connected, if safety strap is not fastened, then safety strap inductive switch 3 is closure state, and this device circuit is connected, ultrasonic distance-measuring sensor 4 work.Described ultrasonic distance-measuring sensor 4 records the objects in front distance, and range signal passed to micro controller system 5, micro controller system 5 changes into digital signal with range signal through A/D, be identified as less than the certain limit micro controller system passenger car is arranged on the seat when this records distance value, start warning 6 reminding passengers and fasten one's safety belt.
