Abstract
The utility model relates to the self-tracing field of intelligent model cars and discloses a tracing apparatus used for the model cars. The apparatus comprises a controller and a tracing plate arranged in front of the model car, and is characterized in that the tracing plate is provided with a comparator and a plurality of horizontally-arranged infrared photocells; infrared rays transmitted by the infrared photocells are downward, and an output signal thereof is input to the controller by the comparator.
Description
Technical field
The utility model relates to the field that independently tracks of model of mind car, relates in particular to a kind of device that tracks of model car.
Background technology
The intellectuality of automobile has become the inexorable trend of industry development, is that the scientific and technological intention of research background is made with the intelligent automobile, and the model of mind car is a kind of engineering practice activity with exploration.Independently tracking is the gordian technique of model of mind car, to the identification of racing track with white background black line with detect research and more and more be subject to people's attention.
Summary of the invention
The purpose of this utility model is to provide that a kind of circuit is simple, cost is low, is subjected to the device that tracks of the little model car of ambient light effects.
In order to achieve the above object, the utility model is achieved by the following technical solutions; A kind of device that tracks of model car comprises: controller and the plate that tracks that is arranged on model car the place ahead, it is characterized in that, and a plurality of infrared photocells of comparer and horizontally set are installed on the described plate that tracks; The infrared ray of described infrared photocell emission is directed downwards, and its output signal is imported described controller through comparer.
Concrete characteristics of the present utility model are:
Described a plurality of infrared photocell is 5, and laterally is evenly arranged on the plate that tracks.
Described comparer is the LM324 chip.
The utility model adopts a plurality of infrared reflection photoelectric tubes as tracing sensor, has reduced the interference of surround lighting with respect to other sensors; Utilize comparer LM324 chip to carry out signal Processing, signal processing circuit is simple, stable performance, cost are low.
Description of drawings
Fig. 1 is the plate scheme of installation that tracks;
Fig. 2 is provided with synoptic diagram for infrared photocell;
Fig. 3 is the infrared photocell circuit theory diagrams;
Fig. 4 is the circuit connection diagram of comparer LM324 chip;
Fig. 5 is comparer LM324 chip input/output signal figure;
Fig. 6 is the racing track synoptic diagram.
Embodiment
With reference to Fig. 1, Fig. 2, model car 2 the plate 1 that tracks is installed, the plate 1 of tracking is made by surface-mounted integrated circuit.Tracking laterally evenly is provided with 5 infrared photocells 3 on the plate 1, and the infrared ray of each infrared photocell 3 emission is directed downwards; A plurality of infrared photocells such as 7,9 also can be set.Comparer also is arranged on the plate 1 that tracks.
With reference to Fig. 3, Fig. 4, with the processing procedure that example describes detection signal that is connected to of an infraluminescence pipe.Infrared photocell D1 is made up of infraluminescence pipe and infrared receiving tube, infraluminescence pipe and infrared receiving tube positive pole be connected 5V voltage respectively, negative their negative pole is respectively by first resistance R 1 and second resistance R, 2 ground connection.The negative pole of infrared receiving tube is exported detected simulating signal X, is input to the 6th pin with comparer LM324 chip then.The 4th pin of comparer LM324 chip connects 5V voltage, the 11st pin ground connection, provide a comparative voltage by adjustable resistance R3 to the 5th pin, the LM324 chip turns to numerical signal Y (as shown in Figure 5) with the simulating signal X dress of infrared photocell output like this, the controller that outputs to model car from the 7th pin processing that tracks.
With reference to Fig. 6, racing track is white base plate 4,30 centimetres of width; Black line 5 is positioned in the middle of the base plate 4,18 millimeters of width.
When model car tracks, to single infrared photocell, send infrared radiation to as shown in Figure 6 racing track by infrared transmitting tube, the infrared ray that reflects through racing track is received by infrared receiving tube.If the infrared radiation that infrared transmitting tube sends is on white base plate, then most of infrared ray will be reflected and return to be received the pipe reception, infrared receiving tube conducting this moment, and output simulating signal X is the magnitude of voltage of 0～1V; If the infrared radiation that infrared transmitting tube sends is on black line, then most of infrared ray will be absorbed, and this moment, infrared receiving tube did not receive most of infrared ray, and output simulating signal X is the magnitude of voltage of 4～5V.The simulating signal X of infrared receiving tube output send comparer to handle in the LM324 chip, comparer LM324 compares this simulating signal with the comparative voltage that configures, if simulating signal X is higher than comparative voltage, comparer output output digital signal Y is 1, otherwise comparer output digital signal Y is 0.
In conjunction with Fig. 1, Fig. 2, Fig. 6, controller is accepted the detection signal of 5 infrared point light pipes output respectively, and the current running orbit that can judge model car is compared with the black line in the racing track and taken back or take over, successively according to the direction of coming the adjustment model car.
Claims (3)
1, a kind of device that tracks of model car comprises: controller and the plate that tracks that is arranged on model car the place ahead, it is characterized in that, and a plurality of infrared photocells of comparer and horizontally set are installed on the described plate that tracks; The infrared ray of described infrared photocell emission is directed downwards, and its output signal is imported described controller through comparer.
According to the device that tracks of the described a kind of model car of claim 1, it is characterized in that 2, described a plurality of infrared photocells are 5, and laterally are evenly arranged on the plate that tracks.
