Go out a kind of children's Vehicular drive system.
Invention content
The purpose of the present invention is to solve disadvantages existing in the prior art, and a kind of automobile-used driving system of the children proposed
System, reduces the welding procedure of the more efficient multiple-printed-panel for circuit board mode and connector of product rejection rate.
To achieve the above object, the present invention provides the following technical solutions：A kind of children's Vehicular drive system, including walk as follows
Suddenly：
S1, motor drive module：Most popular direct current motor drive circuit is exactly H-type full-bridge formula circuit, this driving electricity
Road can easily realize the four quadrant running of direct current generator, corresponding respectively to rotate forward, rotate forward braking, reversion, reverse rotating brake；
The selection of S2, switching tube preferably follow following principle：Since driving circuit is power output, it is desirable that switching tube output power compared with
Greatly, the time that turns on and off of switching tube answers as small as possible, and the supply voltage that trolley uses is not high, therefore the saturation pressure of switching tube
Drop should be low as possible；
S3, tracking refer to that trolley follows black line walking on white floor, and the method being usually taken is infrared detecting method.In small garage
Constantly earthward emit infrared light during sailing, diffusing reflection, reflected light quilt occur when infrared light encounters white papery floor
Reception pipe on trolley receives；Infrared light is absorbed if encountering black line, and the reception pipe on trolley does not receive infrared
Light；
S4, the photoelectric characteristic using phototriode are acted on by comparing the threshold voltage of device LM324, its identification of constantly regulate
Sensitivity sends out corresponding order to obtain seeking optical signal after finally being identified by microcontroller, and then completes to seek the work(of light advance
Energy；
S5, rotation-speed measuring device hardware include interface circuit two parts of pulse generation portion and pulse signal and microcomputer,
The formation of pulse is to be based on Hall effect principle, and several small magnetic sheets are pasted on the couple axle of motor, fixed near couple axle
Hall sensor, then when motor rotates, when each small magnetic sheet passes through Hall sensor, Hall sensor just generates a pulse,
It detects umber of pulse and determines elapsed time, you can calculate the rotating speed of motor, the software of measuring device executes M/T by microcontroller and calculates
Method is realized.
Preferably, the rotating speed of motor is proportional to the voltage at motor both ends, and the voltage at motor both ends and control waveform
Duty ratio is directly proportional, therefore the speed of motor is proportional to duty ratio, and duty ratio is bigger, and motor turns faster.
Preferably, microcontroller is with regard to whether to receive reflected infrared light be according to determining position and the trolley of black line
Track route.Infrared detector detection range is limited, and 15cm is not to be exceeded in general maximum.
The technique effect and advantage of the present invention：Compared with the prior art, has following advantages：Speed automatic control program,
Since supplying cell is different in the electric power of different moments, resistance when bend and straight way is also different, when giving pwm circuit identical duty
When the square wave of ratio, the travel speed of trolley may be different, we use software adjustment program, utilize the return value of vehicle speed sensor
Automatically adjust the travel speed of trolley；Different sections of highway sets different travel speeds, in the driving process of straight-line travelling and bend
Medium velocity is than very fast, and we are travelled using lower speed in avoiding barrier, it is ensured that the reliability of traveling；Software is being set
Timing, using C language and the calling of assembler language with it is nested.Bottom is write using assembler language, and then uses C language high-rise
It is called.Not only make program more succinct in this way, while also improving the reliability of program.
Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below in conjunction with specific embodiment, to this
Invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, not
For limiting the present invention.Based on the embodiments of the present invention, those of ordinary skill in the art are not before making creative work
The every other embodiment obtained is put, shall fall within the protection scope of the present invention.
