Description
Technical field
The invention belongs to include the traffic control system technical field of pedestrian's guided indicator, more particularly to a kind of four-wheel is small
Vehicle guiding blind-man crossing street auxiliary device.
Background technology
Blind person needs the common of various circles of society to help and care about as a kind of specific group in today's society.And China is
The quantity of the most country of whole world blind person's quantity, blind person and people with visual impairment has reached as many as ten million, and it is total to account for whole world blind person
Several 18%, and also in the quantity surge with annual 450000.Due to the vision disorder problem of this types of populations, so that action is very not
It is convenient, especially individually it is outgoing go across the road when this problem it is more prominent, for example it is possible that do not know about current red green
Situations such as wandering off when lamp situation, mistake zebra stripes.Etesian blind person go across the road the casualties number it is not within minority, and review existing
Blind person's auxiliary device market, common device can not safety help blind person go across the road, intelligence the cost of some again it is very high,
General blind person family is all difficult to bear.It is auxiliary that the innovation and creation of Application No. 201620158729.6 disclose a kind of blind-man crossing street
Device is helped, using walking stick insertion is opened in the groove on pavement and by the way of walking stick is made to be moved along groove, realizes and draws
Lead the purpose of blind-man crossing street.The program needs to realize cunning of the walking stick in groove in the case where ensureing groove and walking stick electrical contact
Dynamic, resistance is larger, and groove is easily filled up by the sludge on road.So failure rate is higher when the program is implemented.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of lorry guiding blind-man crossing street auxiliary
Device can not only prevent blind person from wandering off on pavement, and relatively comfortable during use.
To achieve these goals, technical scheme is as follows：A kind of lorry guiding blind-man crossing street auxiliary
Device, including controlling system of traffic light, zebra stripes, guiding crutch, the guiding crutch is connected on a lorry, is located at
Two wheels at lorry rear portion are by DC MOTOR CONTROL, and two wheels positioned at lorry forepart are by the steering engine that can turn to
Control, the front both sides of lorry are respectively provided with 1 electromagnetic sensor, and the electric wire of connection alternating current, electricity are equipped under zebra stripes
Line generates an alternating magnetic field, and when lorry wanders off, variation of the electromagnetic sensor by sensing alternating magnetic field realizes steering engine
The steering of correction property；The beginning and end position of zebra stripes is equipped with the RFID module of belt coil, and guiding crutch is equipped with ID cards, when
When the RFID module of belt coil senses the ID cards of guiding crutch, controlling system of traffic light sends letter by bluetooth to guiding crutch
Number and pass through the current traffic lights situation of loudspeaker voice prompt blind；During the device is additionally provided with ultrasonic module for identifying that blind person moves ahead
Barrier.
As an improvement, the guiding crutch is to be flexibly connected with the connection mode of lorry.
As an improvement, the guiding crutch is a telescopic rod.
The present invention has the advantages that novel in design, operation is simple, can help blind person smoothly by pavement, and due to having
The guiding of lorry uses relatively comfortable.

Specific embodiment
Embodiment 1
As shown in Figure 1, a kind of lorry guiding blind-man crossing street auxiliary device, including controlling system of traffic light 1, zebra
Line 2, guiding crutch 3, guiding crutch 3 are movably connected on a lorry 4, and guiding crutch 3 can be separated or consolidated with lorry 4
Fixed connection.The electric wire 5 of connection alternating current is equipped under zebra stripes 2, electric wire 5 can generate an alternating magnetic field.
Electric wire 5 is a center for being laid on zebra stripes 2, the enameled wire of a diameter of 0.1~1.0mm.Electric wire 5 is connected with
The alternating current of 20kHz, 100mA, frequency range 20k ± 1kHz, 100 ± 20mA of current range.
The beginning and end position of zebra stripes 2 is equipped with the RFID module 6 of belt coil, and guiding crutch 3 is equipped with ID cards, works as band
When the RFID module 6 of coil senses the ID cards of guiding crutch 3, controlling system of traffic light 1 is sent by bluetooth to guiding crutch 3
Signal simultaneously passes through the current traffic lights situation of 45 voice prompt blind of loudspeaker.Loudspeaker 45 are mounted on lorry 4.
As shown in Fig. 2, lorry 4 is by the core in order to control of C51 microcontrollers 41.Two wheels positioned at 4 rear portion of lorry
Son is controlled by direct current generator 42, and two wheels positioned at 4 forepart of lorry are controlled by the steering engine 43 that can be turned to, lorry
Front both sides are respectively provided with 1 electromagnetic sensor 44, and when lorry 4 wanders off, electromagnetic sensor 44 is by sensing alternating magnetic field
Variation make steering engine 43 realize correction property steering.Operation principle is：When blind person, which holds guiding crutch 3, to wander off, the electricity of one side
Magnetic Sensor 44 senses field weakening, and in order to prevent field weakening, electromagnetic sensor 44 generates sensing electric current, by amplifying electricity
Sensing Current amplifier is fed back, by 41 normalized of C51 microcontrollers, carry out data is controlled by C51 microcontrollers 41 by road
The position of discriminatory analysis lorry 4 simultaneously calculates deviation and feeds back to steering engine 43 and make a response, and allows 4 held stationary of lorry
Linear running.The steering of correction property described herein refers to：When lorry 4 wanders off, steering engine 43 is real against the direction to wander off
Existing negative direction deflection, makes lorry 4 return to original track.
The device be additionally provided with ultrasonic module 7 for identify blind person move ahead in barrier.Using C51 microcontrollers 41 in order to control
Core, when barrier appears in the position in 1 meter of blind person front, ultrasonic receiver receive information simultaneously communicates information to buzzing
Device, buzzer, which sounds the alarm, prompts blind person.
As shown in figure 3, guiding crutch 3 is a telescopic rod, the fast of guiding 3 length of crutch is realized by V-type spring leaf 31
Velocity modulation section.
