The operation principle of the present invention is:
Photoelectric sensor 2 is arranged on and is tested the speed on automobile crane 1 front end, has uniformly alternate perforate within photoelectric sensor
Round iron piece 21 be arranged on power transmission shaft 19, due to automobile motor shaft rotation drive power transmission shaft 19, round iron piece 21 is just therewith
Rotate, the uniformly alternate aperture opened above will make the light source of photoelectric tube emitter 20 transmitting pass through the perforate photograph on iron plate
It is mapped to the photoelectric tube light-sensitive element 22 of opposite side, because photoelectric tube light-sensitive element 22 is after by illumination, can be by optical signal
Switch to electric signal output, the light source of photoelectric tube emitter 20 transmitting be illuminated by when being irradiated to the position of non-perforate on iron plate less than
On photoelectric tube light-sensitive element 22, so do not convert optical signal into the signal of telecommunication, therefore will transmit one within a certain period of time high
The one low signal of telecommunication, because resistance r1, resistance r2, resistance r3, photoelectric tube emitter 20, photoelectric tube light-sensitive element 22 form
Photoelectric sensor output signals are faint and height is inconspicuous, so the signal of photoelectric sensor output must be through signal processing
Circuit 3 is processed, and signal is first transferred to the inverting input of Schmidt comparator u2, and resistance r4, r8 play as current limliting
Protection circuit acts on, and resistance r5, r6, r7, r9 and Schmidt comparator u2 constitute the hysteresis loop comparator of reversely input, when apply close
The voltage ratio signal input of special comparator u2 normal phase input end to Schmidt comparator u2 anti-phase input terminal voltage height if, just
Output HIGH voltage, contrary just input low-voltage, then output continuous high-low signal through Schmidt comparator u2, but this
Plant high-low signal periodically height different, so must be through Schmidt comparator u3 and resistance r11, the phase inverter that r12 is constituted
Under process, same r10, r13 play metering function, thus can convert the electrical signal to the height count pulse of a cycle
Signal, therefore drives drive axis by speed, is converted to through photoelectric sensor and signal processing circuit isarithmic
Pulse signal is input to single chip control module 4 and just can calculate speed, and in circuit, vcc is treated storage battery
Pressure+15v.
After speed is calculated, in order to prevent bumping against the front pedestrian travelling on highway, single chip control module 4 is again by vapour
Road section information in car navigation, max. speed max-v limiting including now roadway, calculate with this speed simultaneously
The braking distance d1 of max-v, adds that the people's spacing time that calculates of device just can calculate current safe stopping distance d2,
So carry out people's spacing on the front highway that calculates with single chip processing module 9 to compare, for preventing road two with this distance
The interference of skidding people, available iconology processes and identifies road.Pin pb6, pb7 of single-chip microcomputer lm4f120h5qr and shooting
3,5 pins of head ov7670 connect, and carry out data transmission, so send the photograph of seizure after single-chip microcomputer lm4f120h5qr to
First detect the pedestrian on road, combine, in the principle found range by binocular and pedestrian detection, the distance that just can detect people's car
D, this distance is sent to single chip control module 4 by pin pb3.When needing to reset single chip processing module 9, again count
Calculate distance.That k1 reset key that can push button in chip lm4f120h5qr, when pressing k1 key, the electric capacity c1 of a termination
With regard to fast charging and discharging, thus being initialized.Once safe stopping distance d2 is close with people spacing d, single-chip microcomputer at89c52 is controlled
Molding block triggering whistling device and deceleration device 12, led1 and led2 being simultaneously connected with 1,2 pins of single-chip microcomputer at89c52 will
It is triggered glittering, do so is to improve the attention of pedestrian, chip at89c52 pin 18 connecting resistance r16, electricity in night running
Resistance r16 is connected with audion q1 base stage, and resistance r17 is connected with the colelctor electrode of audion q1, and the emitter stage of audion q1 connects blows a whistle
Device, the whistling device other end is grounded.Once vehicle and people be in non-security apart from when be issued by a signal of telecommunication close to pin 18 and make
Whistling device is reported to the police, and just can push button k2 reset key, when pressing k2 key, one when needing and resetting single chip control module 4
The pull down resistor r15 of termination acts on lower electric capacity c12 with regard to fast charging and discharging, thus being initialized.Simultaneously apart from close when, single
Piece machine at89c52 can be by pin p0.0, p0.1, p0.2, p0.3, p0.4, p0.5, p0.6, p0.7 to address latch chip
74ls373 input address data signal, then decoded by address latch chip 74ls373, address information is sent to storage
Device 6264, after starting the memorizer 6264 that storage is expanded, will ought the pictorial information of road conditions and road speed change for the previous period
Data information memory is got up, as the evidence touching during porcelain, in order to prevent thrusting into, after identification pedestrian, and distance whether safety,
When dangerous, pin p2.0, p2.1, p2.2, p2.3 of single-chip microcomputer at89c52 control module just sends to l298 driving chip 13
Signal, l298 driving chip 13 be the chip of a motor it may also be said to be a current amplifier, so drive fix
After 18 times motors of brake pushrod rotate, threaded rod 14 can be made to rotate reach, and fixation shifted onto by the rubber blanket 16 on threaded rod 14
During iron block 17 on brake pushrod 18, will touch on the brake with people, equally motor 15 is inverted and just can retract threaded rod
16, just reach stopping brake, so periodically allowing motor 15 rotating just can reach slowing effect.
The invention has the beneficial effects as follows: structure is simple, with low cost, is constituted, is connected and make it can be in height by rational
When fast, real-time detection goes out Herba Plantaginis people's spacing, reminds and subtracts in real time once blowing a whistle with regard to intelligence in the range of the braking distance calculating
Speed, the memorizer real-time storage vehicle speed data of extension and people from front spacing and scene situation are to accomplish after accident generation
Voucher.
