Background technology
Along with improving constantly of expanding economy and common people's living standard, the quantity of self-propelled vehicle is constantly increased sharply, and the incidence of traffic accident also is linearly to rise.Casting aside quality, performance and the issuable potential safety hazard of automobile itself, with regard to the subjective situations such as single state that drives a car with regard to people, technical merit, awareness of safety, also is a key factor of generation accident.
The speed of a motor vehicle is too fast to be exactly one of major reason that causes traffic accident.Particularly the automobilist when parking is opened the door owing in time do not see back mirror, ignored situation behind the car and battery-driven car behind this moment car, bicycle etc., again because the speed of a motor vehicle is too fast to be had little time brake and directly hits car door, at this moment just not only the personnel that can cause injure but also can cause damage to property.Prevent the generation of this type of traffic accident, also become the cardinal task of control unexpected injury aspect.
Existing similar open alarm product or patent adopt infrared distance measurement to detect mostly at present, and its shortcoming is disturbed by various thermals source, sunlight source; The passive infrared bite is poor, and the infrared radiation of human body is blocked easily, is difficult for being detected device and receives; Be subject to the interference of radio-frequency radiation; Ambient temperature and human body temperature near the time, survey and sensitivity obviously descends, sometimes cause malfunctioning in short-term.
Summary of the invention
The utility model purpose is the automatic checkout equipment that a kind of safety hit door opening is provided for above-mentioned weak point, utilizes ultrasonic testing, reminds driver's situation and send warning behind the automatic detection vehicle when parking of automobile is prepared to open the door.
The utility model takes following technical scheme to realize: a kind of automatic checkout equipment of safety hit door opening comprises detection alarm device, device body, ultrasonic transduter and control circuit board, ultrasonic transduter is installed on the device body, and control circuit board is installed in the device body; Control circuit and warning circuit are installed on the control circuit board; Be provided with the start detection switch on the detection alarm device, the detection alarm device is installed on the Door Handle, and the detection alarm device links to each other with the input end of control circuit and the mouth of warning circuit by data line; Device body is installed in vehicle body both sides behind the automobile, the vehicle condition behind the inspection vehicle in the range of set value.
Described ultrasonic transduter adopts commercially available Polaroid 6500 Series Ultrasonic sensors, comprises sending sensor and receiving sensor.
Described control circuit has microprocessor, described microprocessor adopts the STC89C52 micro controller system of atmel corp, the mouth of microprocessor links to each other with the transmission sensor, the input end of microprocessor links to each other with receiving sensor, and microprocessor control sends the square-wave pulse signal that sensor outwards sends 40kHz; When sending sensor and running into obstacle, convert reflection echo to electric signal and send to and deliver to microprocessor.Another mouth of microprocessor links to each other with the input end of annunciator, in order to control warning circuit work.
Described warning circuit comprises resistance R 6, crystal triode Q1, transistor diode D1, relay K and loud speaker SP, resistance R 6 one ends link to each other with the mouth of the microprocessor of control circuit, the other end of resistance R 6 links to each other with the base stage of crystal triode, link to each other with the collecting electrode of crystal triode Q1 after transistor diode D1 and the relay K parallel connection, the grounded emitter of crystal triode Q1, the other end of relay K links to each other with the end of loud speaker SP, the other end ground connection of loud speaker SP.Microprocessor automatic screening data, if detect distance greater than setting value, microprocessor output low level then, crystal triode Q1 is in off condition, and relay K is failure to actuate, and loud speaker SP does not report to the police; If instead detect distance less than setting value, microprocessor output output high level, crystal triode Q1 is in saturation conditions, starts warning circuit, the relay K action, loud speaker SP reports to the police, and sends audio alert, reminds the driver to note.
On described device body, also be provided with read-out, the distance that detects in order to demonstration.Described read-out adopts the LED digital display tube, links to each other with the mouth of microprocessor by coding chip, and the range signal that microprocessor is measured is converted into digital signal and outputs on the read-out.
