Embodiment
As shown in Figure 1, the utility model 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 installed on the axle of motor, gear wheel engagement with compound gear, consist of the first order and slow down, the pinion wheel of compound gear and gear wheel engagement consist of the second level and slow down, two differential driving wheels are fixed on the right and left of dolly pedestal, by belt gear, belt one end is fixed in the groove of reducer casing take-off (propeller) shaft, and 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, by belt gear, can play the effect of deceleration, be used the rotating speed that greatly reduces motor output with reducer casing.
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.
It is excessive to consider that direct-flow small motor starts immediate current, can affect control chip part power supply, so employing dual power supply, pass through photoelectric coupling technology, minute control section and each one road Power supply of motor-driven part, two road power supplys altogether, the I/O mouth is exported control signal, by photoelectric coupling control signal input LB1836M DC MOTOR CONTROL chip, by the DC MOTOR CONTROL chip to dolly advance, retreat, 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 through after the reflection of reverberation, so must be that white floor adds the black guide line when using infrared tube to track, the signal that the ARM master control borad collects is treated signal, only have two values of low level and high level, make things convenient for the ARM master control borad to the collection of signal, being low level when the signal that finally obtains shines on the black, is high level when shining on the white.
The photoresistance that optical switch module adopts semiconductor material to make, light characteristics by photoresistance, when illumination, the characteristics that resistance reduces, between the metal electrode at photoresistance two ends, add voltage, wherein just have electric current to pass through, when being subject to the light irradiation of suitable wavelength, it is large that electric current will become with the increase of light intensity, thereby realization opto-electronic conversion, photoresistance does not have polarity, is a resistance device purely, both can add DC voltage during use, also can add alternating voltage, when voltage reached the 3V left and right sides, the OUT output low level was when photoresistance is subject to natural light irradiation, resistance is larger, it is more to assign to voltage, so the voltage of input trigger is exported high level (supply voltage) just less than 3V; When using illumination, such as the electric torch irradiation, the resistance of photoresistance can sharply descend, almost close to 0, so the variable resistor dividing potential drop becomes many, triggers the trigger output LOW voltage during strong illumination, 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 the magnetic field, and when direction of current is vertical with magnetic direction, produce Hall voltage UH at the transverse side perpendicular to the semiconductor chip of electric current and magnetic flux, the height of Hall voltage UH is directly proportional with the electric current I of passing through and magnetic induction density B, Hall open the light amplitude that signal amplifier in the integrated circuit produces Hall element amplify with the Hall voltage UH of change of magnetic field strength after again through signal converter, output amplitude equated after driver carried out the shaping amplification, the square-wave signal of frequency change utilizes hall device just can realize the collection to wheel information by the permanent magnet on the wheel like this.
The sensor of air acquisition module adopts TP4 type normal temperature gas sensor, sucks ambient air by mini fan, carries out the air quality data collection by sensor, and is shown on the liquid crystal display, is stored in the 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.
