Be fixed on 1 both sides of fixinig plate and medium position, can respectively at left and right sides of bicycle and rear formed three on the ground swash
Light projects 13, and driver seems that stereo space sense is stronger with allowing front vehicle；Range finder module 2 is fixed on fixinig plate 1, can be with
The distance of the object distance bicycle of rear or both sides is detected, then by Distance Transmission to controller；Controller can be set in advance
A fixed safe distance value, when distance is less than or equal to the safe distance value of setting, controller can control three words
Laser carries out the flicker for having frequency so that three laser projections 13 of ground are beated, and allow rear driver or riding personnel to see
That eyes are not easy to fatigue, the lines of bounce are more obvious than static lines, improve warning.
Further, range finder module 2 is ultrasonic distance measuring module or infrared distance measuring module；It can sense and measure rear
Or the distance of the object distance bicycle of both sides, and the data measured are reached into controller.
Further, controller is microcontroller.
Further, range finder module 2 is fixed on fixinig plate 1 with glue, can also be fixed using lifting apparatus, can be with
Range finder module is directly anchored in bicycle other positions using other structures.
Further, controller is fixed on fixinig plate with glue, can also be fixed, can also use using lifting apparatus
Other structures are directly anchored to range finder module in bicycle other positions, ensure the feasibility of single unit system.
Further, 1 both sides of fixinig plate and medium position are equipped with mounting hole 12, and a word laser is fixed on mounting hole 12
In；Medium position can be middle and upper part or middle and lower part, can also be other middle parts；Ensure a word laser voluntarily
At left and right sides of car and rear forms three laser projections 13 on the ground.
Further, fixinig plate 1 is fixed on present bar 3 by fixing piece 4；Its that can be in practical range can also be fixed on
His position.
Further, as shown in Fig. 2, 1 back side of fixinig plate is equipped with card slot 5.
Further, as shown in Fig. 2, fixing piece 4 includes clip 6, screw 7, nut 8 and gets stuck 9；Get stuck 9 be equipped with and card
The protrusion 10 that groove 5 matches, its back side are equipped with protrusion 11, and protrusion 11 is equipped with the connecting hole passed through for screw 7.Fixinig plate
1 can be matched to fixation by the protrusion 10 of card slot 5 and fixing piece 4；Can also be directly in the boring bolt arrangement on 9 that gets stuck
Fixinig plate 1 is fixed；It can also be fixed using other viable means.
Further, buzzer is further included in the present invention, buzzer is fixed on bicycle and is connected with controller；Work as spy
When the distance for the object distance bicycle for surveying rear or both sides is less than setpoint distance value, controller passerby around visual alerts
Or it can be reminded while vehicle with sound；Can also sound alternate and warned with laser projection 13, into one
Step ensure that the safety of bicyclist.Certainly, sound can also carry out warning function to bicyclist itself, in order to avoid when notice does not collect
Bumped against when middle on other objects and cause unnecessary loss.
In an embodiment of the present invention, range finder module 2 is HC-SR04 ultrasonic distance measuring modules, this module can provide 2cm-
The contactless distance sensing function of 400cm, including ultrasonic transmitter, receiver and control circuit.Operation principle：Using I/
O mouthfuls of TRIG trigger ranging, and at least high level signal of 10us, module sends the square wave of 8 40Khz automatically, and automatic detection is
No to have signal return, if signal passes back through one high level of I/O mouthfuls of output, high level lasting time is exactly from being transmitted to
The time of return.Measuring distance=（The high level time * velocities of sound（340M/S））/ 2, its System Working Principle is as follows：Microcontroller
The square-wave signal ripple signal that P1.0 mouthfuls of output frequencies are 40kHz, drives ultrasonic transmitter after power amplification, is allowed to send same
The super formula of frequency carries out sound wave position number, and at the same time counter starts timing.Ultrasonic signal is met barrier reflection and is reflexed to super
Acoustic receiver.Obtain being effectively formed interrupt signal after being put into processing and shaping pulse, be sent into the INTO mouths of microcontroller, make
The INTO of microcontroller produces interruption, and counter stops timing, so can be obtained by ultrasonic wave from being transmitted between the time of reception
Every AP.Range measurement principle is put by ultrasound to know, the distance between Ben Che and barrier d are the spread speed V of d=v*AU2 and ultrasonic wave
Related with environment temperature 1, the relation between them is:- 331.45+0.611, when d numerical value exceed system as defined in safely away from
During from size, start caution system.
In the present invention in another embodiment, controller is STC89C52RC microcontrollers, 8k bytes Flash, 512 bytes
RAM, 32 I/O mouth lines, WatchDog Timer, built-in 4KBEEPROM, MAX810 reset circuits, 3 16 bit timing devices/countings
Device, 4 external interrupts, one 7 vectorial 4 grades of interrupt structures（5 vectorial 2 grades of interrupt structures of compatible tradition 51）, full duplex is serial
Mouthful；In addition, STC89C52 can be down to the operation of 0Hz static logics, support 2 kinds of softwares that energy-saving mode may be selected.At the idling mode,
CPU is stopped, it is allowed to which RAM, timer/counter, serial ports, interruption work on；Under power down protection mode, RAM contents
It is saved, oscillator is frozen, all work of microcontroller stop, untill next interruption or hardware reset.
Using the timer 1 inside the timer inside microcontroller, working method 0 and external interrupt 0, when external interrupt 0
After receiving the signal that ultrasonic wave module is sent, because external interrupt 0 is low level triggering, external interrupt 0 is just by height before
Level is changed into low level, then timer begins to work at this time, controls laser head with the frequency scintillation of interval 1S；It is wherein fixed
When device operation principle：Timer inside microcontroller is to be arranged to timer also by counter to switch different operating modes
It is counter, if configured to 1 pattern is exactly counter, is exactly timer if provided as 0 pattern, is arranged to fixed at this time
When device pattern, add 1 counter be to the internal machine cycle count (1 machine cycle is equal to 12 cycles of oscillation, i.e. count frequency
For crystal oscillator frequency 1/12).It is exactly timing t that count value N, which is multiplied by machine cycle T,.
In another embodiment in the present invention, a word laser is a word laser lamp head, it has monochrome to act charitably, coherence
Good, the advantages that directionality is fabulous, high brightness, working life when 1000 is small more than；Optical maser wavelength is 650nm, power 50mW, electricity
3V, electric current ＜ 20mA are pressed, operating temperature is -36 DEG C~65 DEG C；Storage temperature is -36 DEG C~65 DEG C, spot size：At 15 meters
