Below in conjunction with the accompanying drawings this utility model is described in detail.

Seeing Fig. 1, this utility model is made up of guide 1 and the body part being connected with guide 1.Described body portions Point include data processing equipment 2-1, tracking device 2-2, Ultrasonic ranging device 2-3, transfer 2-4, driving means 2-5, Sound prompt device 2-6 and display device 2-7.Wherein, tracking device 2-2, Ultrasonic ranging device 2-3, transfer 2-4, Driving means 2-5, sound prompt device 2-6 and display device 2-7 are all connected by parallel port with data processing equipment 2-1, and lead to Cross and take P0 mouth and carry out parallel port communication.Guide 1 is connected with tracking device 2-2, utilizes the mode of optical communication, carries out wireless Unidirectional information is transmitted；Each device of the present utility model all uses modularized encapsulation, it is easy to dismantles, install.Thus facilitate equipment Increase and replacement.

See Fig. 1, sound prompt device 2-6 and select built-in, reduce the external environment condition interference to voice messaging；Sound prompt device 2-6 is made up of WTV020-SD voice module and the speaker that is connected with WTV020-SD voice module.This utility model With display device 2-7；Display device 2-7 selects 3.2 cun of display screens as display module, and clear presents all kinds of survey Data.

The principle of the intelligent carriage of this laser aiming:

1. laser aiming

The principle linearly propagated according to light, tracking device 2-2 includes reflecting optics 2-22 and 5 laser pick-off pipe 2-21 compositions Horizontal laser accepts array structure and refers to Fig. 2.Wherein, 5 laser pick-off pipes are specifically arranged as follows, 1 laser pick-off pipe position In centre, the side of this laser pick-off pipe arranges 2 laser pick-off pipes, and opposite side arranges 2 laser pick-off pipes.

2. optical communication

This use is novel closely to link together guide 1 and tracking device 2-2 by the way of optical communication, and energy Enough complete the unidirectional information transmission between guide 1 and tracking device 2-2.

3. carry screen to show and voice message

The intelligent carriage of this laser aiming carries screen and shows, measurement data is presented in front of the user in real time.Sound prompt device 2-6 is made up of with speaker WTV020-SD voice module, by data processing equipment 2-1 pair during reversing warehouse-in WTV020-SD voice module is controlled, and plays voice in good time and carries out each item data measured when voice message user puts in storage.

4. ultrasonic ranging

Ultrasonic ranging device 2-3 in the intelligent carriage of this laser aiming uses ultrasound measurement module HC-SR04, utilizes ultrasound wave Aerial speed it is known that measure sound wave after transmitting, run into the time that barrier reflects, according to launch with receive time Between difference calculate the distance between launch point and barrier.

Its range finding formula is:

L=C × T (1)

In formula, the distance measured for L, C is the aerial spread speed of ultrasound wave, and T is the time difference measuring propagation The half of the time numerical value being transmitted into reception (T be).

Spread speed C=344m/s (20 DEG C of room temperatures) of known excusing from death ripple, the spread speed of ultrasound wave receives the density of air to be affected, The density of air is the highest, and the spread speed of ultrasound wave is the fastest, and the density of air has close relationship with temperature.

Approximate formula is:

C=C₀+0.607×T (2)

In formula: C is the aerial spread speed of ultrasound wave, C₀For SVEL 332m/s during zero degree；T is actual temperature (℃)。

5. data process

51 single-chip microcomputers that the intelligent carriage of this laser aiming is easily understood as data processing module, by the way of parallel port communication, Coordinate modules work.

6. drive and turn to

The transfer 2-4 of the intelligent carriage of this laser aiming and driving means 2-5 are respectively adopted S3003 steering wheel and L298N electricity Machine drives, and the working method of its S3003 steering wheel and L298N is as follows: pwm signal is by receiving passage entering signal demodulator circuit 12 feet of BA6688 are demodulated, it is thus achieved that a DC offset voltage.The voltage ratio of this DC offset voltage and potentiometer relatively, Obtain voltage difference by the 3 foot outputs of BA6688.Motor driving integrated circuit BAL6686 is sent in this output, to drive motor just Reversion.When electric machine rotation, driving potentiometer Rw1 to rotate by cascade reduction gearing, until voltage difference is O, motor stops Rotate.

Work process of the present utility model is:

First, inside garage, generating laser is placed.The laser beam gone out when laser transmitter projects is beaten at photodetector system Reflex reflector lens 2-22 on, by reflex reflector lens 2-22, laser beam is reflexed to laser and accepts the laser pick-off pipe 2-21 of array On.When laser beam is beaten on Centromedian laser pick-off pipe, laser pick-off pipe 2-21 is to STC89C52RC type single-chip microcomputer Returning high level signal, by program setting, when central authorities' laser pick-off pipe returns high level, dolly travels to dead ahead；If beating On two laser pick-off pipes on the left side, the laser adopter on the left side will return high level signal, illustrates that trolley is the most inclined Zuo Liao, needs to turn right.STC89C52RC type single-chip microcomputer sends high level to steering wheel, makes it turn right, therefore dolly turns to the right； In like manner, if beating on laser pick-off pipe on the right, dolly turns to the most to the left, finally realizes automobile balance warehouse-in.

In this utility model, guide is connected by the way of optical communication with tracking device, and can complete one-way communication； Other parts are then connected by internal circuit, complete the information transmission between each several part with this.Described data processing equipment is letter Single easy-operating 51 single-chip microcomputers, coordinate the work of modules by it；The effect of described tracking device is to accept laser, will The signal received is transferred to steering wheel, guides steering module to play a role；Described range unit uses ultrasonic wave module, according to it Set minimum range, when dolly is soon close to garage or barrier, dolly will self-actuating brake, warehouse-in.

This utility model is simple to operate, easily controllable.It provides voice message and plane display function, and user can be carried by voice Show with screen shown by data, complete the control to dolly.Without too much personnel intervention, save manpower.It addition, The good stability of this utility model system, environmental suitability strengthens.
