Embodiment
As shown in Figure 1, the invention discloses a kind of Detection of Air Quality robot, this robot comprises the circular dolly pedestal that diameter is 20cm, the dolly pedestal is provided with the chassis external member, the chassis external member comprises three wheels, FF-N20PA motor and secondary speed reduction box combination, three wheels comprise a globular universal wheel and two differential driving wheels, the reducer casing combination is by pinion wheel, meeting gear and gear wheel forms, pinion wheel is arranged on the axle of motor, gear wheel engagement with compound gear, forming the first order slows down, the pinion wheel of compound gear and gear wheel engagement, forming the second level slows down, two differential driving wheels are fixed on the right and left of dolly pedestal, pass through belt gear, belt one end is fixed in the groove of reducer casing take-off (propeller) shaft, the other end is fixed in the groove of wheel belt, the degree of tightness of belt can be regulated by the adjusting screw on chassis, pass through belt gear, can play the effect of deceleration, be used in conjunction with reducer casing the rotating speed that greatly reduces motor output.
The dolly pedestal is provided with robot system, robot system comprises dual power supply, ARM master control borad, LB1836M control chip, infrared tube track module, optical switch module, Hall element sampling module, air acquisition module, LCD MODULE and data memory module, the air acquisition module comprises mini fan and sensor, and LCD MODULE comprises liquid crystal display control chip and liquid crystal display.
Wherein, master control borad adopts the ARM development board.
Consider that direct-flow small motor starts immediate current excessive, can affect control chip part power supply, so employing dual power supply, pass through photoelectric coupling technology, divide and control part and motor driving part Fen Ge mono-road Power supply, altogether, the I/O mouth is exported control signal to two road power supplys, by photoelectric coupling control signal input LB1836M DC MOTOR CONTROL chip, by the DC MOTOR CONTROL chip to dolly advanced, retreated, a series of actions such as turning.
The infrared tube module that tracks adopts the reflective infrared tube of one, the reflective infrared tube of one is that power valve and receiving tube are fixed together, reflective principle of work is that the signal that receiving tube receives is that the infrared light that power valve sends obtains after the reflection of reverberation, so must be that white floor adds the black guide line while using infrared tube to be tracked, the signal that the ARM master control borad collects is treated signal, only have two values of low level and high level, facilitate the collection of ARM master control borad to signal, it when the signal finally obtained shines on black, is low level, while shining on white, it is high level.
The photoresistance that optical switch module adopts semiconductor material to make, light characteristics by photoresistance, when illumination, the characteristics that resistance reduces, add voltage between the metal electrode at photoresistance two ends, wherein just there is electric current to pass through, while being subject to the light irradiation of suitable wavelength, it is large that electric current will become with the increase of light intensity, thereby realize opto-electronic conversion, photoresistance does not have polarity, a resistance device purely, both can add DC voltage during use, also can add alternating voltage, when voltage reaches the 3V left and right, the OUT output low level, when photoresistance is subject to natural light irradiation, resistance is larger, assign to voltage more, therefore the voltage of input trigger just is less than 3V, output high level (supply voltage), when using illumination, such as electric torch irradiates, the resistance of photoresistance can sharply descend, during strong illumination, almost close to 0, so the variable resistor dividing potential drop becomes many, triggers the trigger output LOW voltage, just can control dolly by illumination with the low level triggering and advance, reach the effect of switch.
As shown in Figure 2, the Hall element sampling module, when electric current I by being placed on the semiconductor chip (Hall element) in magnetic field, and when direction of current is vertical with magnetic direction, produce Hall voltage UH on the transverse side of the semiconductor chip perpendicular to electric current and magnetic flux, the height of Hall voltage UH is directly proportional to the electric current I of passing through and magnetic induction density B, the amplitude that the signal amplifier that Hall opens the light in integrated circuit produces Hall element with the Hall voltage UH of change of magnetic field strength, amplify after again through signal converter, after driver carries out the shaping amplification, output amplitude equates, the square-wave signal of frequency change, utilize like this hall device just can realize the collection to wheel information by the permanent magnet on wheel.
The sensor of air acquisition module adopts TP4 type normal temperature gas sensor, by mini fan, sucks ambient air, carries out the air quality data collection by sensor, and is shown on liquid crystal display, is stored in memory module simultaneously.
Liquid crystal display adopts monochromatic 84*48 lattice lcd screen.
Data memory module adopts the TF draw-in groove of plug and play.
