Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, this utility model is described further:
K60 single-chip microcomputer 1 is arranged on substrate 9 rear end upper surface, and power module 3 is arranged on upper surface in the middle part of substrate 9；L298N
Motor drive module 10 is arranged on substrate 9 middle lower surface；Steering wheel 6 is arranged on substrate 9 front end, and is arranged in front-wheel support 7
Portion, by being mechanically connected, controls the rotation of front-wheel support 7；Photographic head 4 is arranged in the middle part of the cross tube of camera bracket 5, shooting
Head bracket is arranged on front-wheel support 7, rotates along with the rotation of front-wheel support 7, to guarantee to collect front truck information always；
Direct current generator 11 is nested in the body of differential mechanism 12, after direct current generator 11 and differential mechanism 12 are mechanically connected and are arranged on substrate 9
End lower surface, differential mechanism 12 and back axle 13 are mechanically connected to drive rear wheel 2 to rotate；Steering wheel 6, L298N motor drive module
10 and ov7620 photographic head 4 are electrically connected with K60 single-chip microcomputer 1 by Du Pont's line；Power module 3 is by power supply alignment K60 monolithic
Machine 1, direct current generator 11 and L298N motor drive module 10 is powered.
The intelligent laboratory vehicle being based on camera sensing device as shown in Figure 1, is caught in the middle of front truck rear portion by photographic head 4
The car plate shape information of position, passes information to single-chip microcomputer 1, single-chip microcomputer 1 analyze the area of car plate institute in photographic head
The pixel quantity taken, determines the following distance of dolly and front truck；The car plate pixel quantity analyzed when single-chip microcomputer 1 is less than
Setting value, illustrates that following distance is excessive, strengthens the pulse to motor drive module 10 and exports, makes direct current generator 11 accelerate revolution,
Dolly back axle 13 and rear wheel 2 is driven, it is achieved the increase of speed by differential mechanism 12；When the car plate picture that single-chip microcomputer 1 is analyzed
Vegetarian refreshments quantity is more than setting value, illustrates that following distance is too small, reduces the pulse to motor drive module 10 and exports, makes direct current generator
