Abstract
The utility model discloses a kart protects alarm device, include single chip microcomputer control center and ultrasonic wave circuit as the main control unit. The utility model discloses kart protects alarm device adopts the ultrasonic ranging method to carry out the precision measurement to kart with front truck or pedestrian's distance to carry out the numerical display through the display screen, can also carry out acousto -optic warning when the distance is less than the risk distance, even remind the driver to slow down or park, simple structure, stable performance, convenient to use is fit for using widely.
Description
Technical field
The utility model relates to a kind of car protective device, specifically a kind of miniature car protection warning device.
Background technology
Along with socioeconomic continuous progress and high-tech develop rapidly, in routine and life, automobile has become the desirable vehicle of people, but a lot of new hand can run into such problem when just learning driving, the operator's saddle being sitting in miniature car cannot see headstock, especially the driver that stature is not high, therefore a lot of cannot the distance of accurate assurance and front truck to the unfamiliar new hand that drives, often red light can be run into again in the city blocked up, the situations such as traffic congestion need slowly with car, seldom there is the fender guard for monitoring following distance in the market, cause a lot of accident unfamiliar driver of vehicle being occurred to knock into the back.
Utility model content
The purpose of this utility model be to provide a kind of highly sensitive, effectively can place the miniature car protection warning device that vehicle knocks into the back with car, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of miniature car protection warning device; comprise the Single-chip Controlling center as main control unit and ultrasonic circuit; it is characterized in that; described ultrasonic circuit comprises ultrasonic transmit circuit and super sonic acceptor circuit, and described Single-chip Controlling center connects ultrasonic transmit circuit, super sonic acceptor circuit, button, crystal oscillator, warning circuit, read-out and power circuit respectively.
As preferred version of the present utility model: the main control unit at described Single-chip Controlling center is the special monolithic integrated circuit of SB5027 type ultrasonic ranging.
As preferred version of the present utility model: described read-out is the digital display screen of 7 segment numeral pipe compositions.
As preferred version of the present utility model: described warning circuit is the sound and light alarm of LED light-emitting diode and buzzer phone composition.
Compared with prior art; the beneficial effects of the utility model are: the utility model miniature car protection warning device adopts the distance of ultrasonic ranging method to miniature car and front truck or pedestrian accurately to measure; and carry out numeral instruction by read-out; sound and light alarm can also be carried out when distance is less than danger range; even if remind driver to slow down or stop; structure is simple, stable performance, easy to use, is applicable to promoting the use of.
Accompanying drawing explanation
Fig. 1 is the structured flowchart of miniature car protection warning device;
Fig. 2 is the circuit diagram of Microwave emission circuit;
Fig. 3 is the circuit diagram of microwave receiving circuit.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-3; a kind of miniature car protection warning device; comprise the Single-chip Controlling center as main control unit and ultrasonic circuit; it is characterized in that; described ultrasonic circuit comprises ultrasonic transmit circuit and super sonic acceptor circuit, and described Single-chip Controlling center connects ultrasonic transmit circuit, super sonic acceptor circuit, button, crystal oscillator, warning circuit, read-out and power circuit respectively.
The main control unit at Single-chip Controlling center is the special monolithic integrated circuit of SB5027 type ultrasonic ranging.
Read-out is the digital display screen of 7 segment numeral pipe compositions.
Warning circuit is the sound and light alarm of LED light-emitting diode and buzzer phone composition.
Principle of work of the present utility model is: the groundwork of ultrasonic ranging is substantially identical with the principle of sonar echolocation.Projector T40 in ultrasonic transmit circuit constantly sends 40kHz super sonic, runs into obstacle and is reflected back backward wave, and the CX20106A in super sonic acceptor circuit receives reflection wave signal, and is changed into electric signal.Measure the time difference T of the emitted wave launched and the backward wave received, can obtain distance, ultrasonic transmit circuit shown in Fig. 2 is made up of Schmidt trigger U1 ~ U2, voltage transformer T, emission sensor T40.Because there is the ultrasonic generator of standard 40kHz SB5027 inside, so directly draw its internal signal, but this signal is more weak, also signal must be amplified in transmission circuit part.This signal is connected in series through two reverse binary pair U1 ~ U2 of Schmidt, make aerotron VT1 conducting by divider resistance R2 simultaneously, and the voltage pulse signal of mouth is fed back on voltage transformer T, through step-up transformer, voltage signal is increased, order about the super sonic that emission type T40 sensor outwards launches 40kHz, CX20106A signal receiving chip in super sonic acceptor circuit shown in Fig. 3 by the backward wave received by converting voltage signal to through LM331 after electric capacity C1 and resistance R5 filtering, Single-chip Controlling center is delivered to again after LM331 is changed the voltage gain shaping of coming by two reverse Schmidt trigger U3 ~ U4 serial connections, by button, alarm distance is set, when the distance that super sonic is measured is less than alarm distance, light-emitting diode in warning circuit and buzzer phone send sound and light alarm, even if remind driver to slow down or stop, actv. is avoided knowing clearly the infringement that driver causes to vehicle because accurately judging spacing.
