Embodiment
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.
With reference to Fig. 1-6, this embodiment is by the following technical solutions: campus sightseeing automatic guide tourist bus, comprise tracking modules A, fixed point detection module B, single-chip microcomputer C, motor drive module D, avoiding obstacles by supersonic wave module E and Liquid Crystal Module F, single-chip microcomputer C is connected with Liquid Crystal Module F with tracking modules A, the detection module B that fixes a point, motor drive module D, avoiding obstacles by supersonic wave module E respectively, and described single-chip microcomputer C model is AT89C51; Described single-chip microcomputer C is also connected with ISD4003 speech chip, provides voice service.
Described tracking modules A comprises the first light emitting diode D1, second light emitting diode D2, first resistance R1, second resistance R2, 3rd resistance R3 and voltage comparator AR1, first light emitting diode D1 positive pole, second light emitting diode D2 negative pole, 3rd resistance R3 one end, voltage comparator AR1 is connected, first light emitting diode D1 negative pole meets the first resistance R1 to earth terminal, second light emitting diode D2 positive pole meets the second resistance R2 respectively to earth terminal, 3rd resistance R3 one end, voltage comparator AR1 end of oppisite phase, 3rd resistance R3 other end ground connection, the in-phase end of the slip termination voltage comparator AR1 of the 3rd resistance R3, described voltage comparator AR1 model is LM324.
This embodiment tracking part adopts infrared ray transmitter and receiver to realize pipe, wherein power valve continues to send infrared ray, receiving tube property class is similar to photodiode, when extraneous illumination condition changes, flows through its electric current and linearly changes with intensity of illumination.After series connection divider resistance ground connection, the pressure drop of resistance two ends is then followed intensity of illumination change and changes. now suppose the colour band having a color different from ground on the ground, whether probe just can show in the form of a voltage in colour band, base area face look different with colour band color, the electric potential signal of two kinds of color generations is also just different, recycling LM324 voltage comparator, signal voltage connects in-phase end, calibrating signal connects end of oppisite phase, calibrating signal current potential gets a certain value between the inside and outside signal voltage produced of colour band, then pop one's head in and whether just can reflect with the form of 1/0 in colour band.And mouthful INT0/INT1 that accesses terminal.Physical circuit asks for an interview Fig. 2.
Fixed point detecting portion circuit and tracking part adopt same principle.Output meets counter pin T0.Native system is at appointed place place, draw a very little mark just can complete fixed point detect on driving line side, after obtaining detection signal, output signal to single-chip microcomputer, corresponding explanatory note is exported from liquid crystal display after single-chip microcomputer obtains signal, be introduced corresponding view, simultaneously supporting speech chip exports voice and introduces content.Sound chip circuit is shown in Fig. 3.
Governor circuit adopts AT89S51 to be control chip.AT89S51 is the low-power consumption that American ATMEL is produced, high performance 8 single-chip microcomputers, containing 4K bytes in sheet can the Flash read-only program memory of System Programming, device adopts the high density of atmel corp, nonvolatile storage technologies is produced, compatible 8051 order set and pin.Support the programmed method of ISP online programming and traditional mode.
The turning function of native system and advancement function respectively adopt a direct current generator to realize.Because single-chip processor i/o driving force is difficult to promote direct current generator, so devise corresponding peripheral power amplifier, motor is driven.For steer motor, Fig. 4 is shown in by this part circuit diagram.
The barrier avoiding function of native system adopts ultrasound wave launch and accept probe, and collocation CX20106 ultrasound wave, infrared receiver chip and LM386 audio frequency power amplifier carry out signal and amplified.LM386 has adjustable gain, stable output, and the good characteristics such as high s/n ratio are by people's widespread use, and CX20106 is modal chip in infrared ray and ultrasonic instrument especially, the feedback signal of Receiver is carried out adopting transmission of signal to single-chip microcomputer by it.40KHz square wave is sent by single-chip microcomputer, power amplification pusher is carried out to emitting head TX1 through LM386, this signal transducing is that ultrasound wave is launched by emitting head, be passed back after ultrasound wave is reflected by barrier, square wave is exported pass to CX20106 process after Receiver RX1 receives after, this output can connect single-chip microcomputer interrupt pin, and square wave negative edge just can perform by demand by trigger.Physical circuit is shown in Fig. 5, Fig. 6.
The concrete function of this embodiment realizes:
1, automatic running: general campus area is all larger, and visit personnel are difficult to reasonable arrangement tour, so design most scientific rational travel route in advance by this school personnel, and the form with white line on road in campus marks route.The travel route automatic running that native system can make tour bus design in advance according to us.
2, fixed point detects: sentence dot for mark is for system identification there being the sight spot of ornamental value.System is stopped at sight spot place automatically, while people's sight-seeing spot, introduce sight spot relevant information with the form of captions and voice.
3, barrier avoiding function: because the pedestrian on the road of campus is more, automatic stopping this function can have a pedestrian in the certain distance of tour bus front also gives a warning, and to ensure pedestrains safety on road, prevents traffic accident.
Native system application scm observe and control technology, is core with AT89S51, realizes tour bus unmanned, and to light signal collection, process and output control.Apply width modulation to regulate and control drive motor when tour bus is turned and there is pedestrian in front simultaneously.Directly cut off tour bus power supply and emergency brake when pedestrian is excessively near, ensure safety.A whole set of control system is combined with tour bus, can realize the automatic guiding of whole system, all brings conveniently to visitor and school side's management.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
