Description
Technical field
The utility model relates to the special-purpose timer of a kind of intelligent vehicle racing track.
Background technology
The timer that uses for the close games results of the judgement of justice in the intelligent vehicle contest at present is complexity and fetch long price relatively, and the debugging that is not suitable for daily player is used.
Summary of the invention
In order to overcome system complex and the expensive shortcoming that timer exists in the existing intelligent vehicle contest, the utility model provides a kind of intelligent vehicle racing track special-purpose timer.
The technical solution adopted in the utility model is:
The special-purpose timer of intelligent vehicle racing track, comprise timer body and photoelectric sensor, it is characterized in that: described timer body comprises single-chip microcomputer, LED display, hummer, selection key and power switch, described power switch is electrically connected with described single-chip microcomputer by the voltage stabilizing chip, and described single-chip microcomputer is connected with described LED display, hummer and selection key respectively; Described photoelectric sensor is arranged on racing track timing point one side and is connected with described single-chip microcomputer, and when racing car process timing point, described photoelectric sensor is gathered racing car and also is sent on the described single-chip microcomputer through signal.
Further, described selection key comprise reset button, withdraw from/arrange button, button and to knob down upwards.
Further, described photoelectric sensor is that the infrared electro emission receives the one pipe.
Further, described timer has the 6-12V voltage interface, and described voltage interface can link to each other with multiple source of stable pressure.
When the utility model uses; when vehicle crosses from racing track; after being detected by photoelectric sensor, the triggering timing device picks up counting and the buzzer prompting is arranged; can not trigger again in the 500ms and prevent false triggering; stop timing when being triggered again and point out with buzzer, show and the current achievement of automatic memory, trigger if in setting timing range, detect for the second time; after overflowing, timer stops timing and zero clearing, the time overflow protection.Long by " upwarding key " or " down Arrow " but the query history achievement, the constantly flicker of LED display this moment.Withdraw from query State by " setting/ESC Escape ".Length can enter timing range by " setting/ESC Escape " state is set, and can arrange by " upwarding key " or " down Arrow ", and be set scope 10-990 second, withdraws from by " setting/ESC Escape ".
The utility model photoelectric sensor adopts the infrared electro emission to receive the one pipe, and the mode of the passive acceptance of active illuminating detects the racing track situation.Sensor is made of an infraluminescence pipe and a receiver pope, and the infrared light that returns that is reflected if the light that sends when infrared luminotron stops in certain distance is received by the receiver pope in the same side, and namely judging has the car mould to cross.This testing circuit is simple in structure, and scheme is mature and stable reliable, and it is adjustable to detect distance, not influenced by ambient light, more can not disturb intelligent vehicle to compete normally.Only need to install in racing track one side, can realize detecting, convenient and simple.Obtain the standard square wave after the rectification of receiving tube signal process comparer, send into single-chip microcomputer as interrupt trigger signal.
The utility model timer is researched and developed based on 51 single-chip microcomputers, and is cheap, stable performance, and diverse in function can realize 0.001 second timing of precision, timing range is adjustable 10-990 second, the automatic clear stopwatch that goes beyond the scope is fit to multiple timed game requirement.And the function with nearest 6 track records satisfies the needs of team participating in the contest's test carriage mould fully.
The utility model 51 singlechip antijamming capabilities are strong, are fit to various working environments.LED display is as display element, and photoelectric sensor is as detecting sensor, and different with timer in the past is need only need not be sidelong one and put sensor at racing track both sides sensor installation.Under the control of single-chip microcomputer, configure timer, realization 0.001 second timing of precision and error are not accumulated the low problem of accuracy of timekeeping that solved.When triggering again, this timer can realize continuous unattended timing by automatic clear.Has the function that shows nearest 6 track records.Can manually set timing range; exceed stopwatch automatic clear behind the timing range, realize the timing overflow protection, the design philosophy of the house dog of single-chip microcomputer inside has been used for reference in this design; improve the anti-interference of system effectively, reduced the trouble of manual maintenance in the actual use widely.By the program timing optimization, eliminate LED display and shown the phenomenon of trailing, solved the problem of poor definition when the common display screen dynamically shows, and man-machine interaction is simple and practical.
The beneficial effects of the utility model are embodied in: adopted 51 single-chip microcomputer accuracy of timekeeping height; functional reliability is strong; cheap; have timing and overflow automatic protection functions; strong interference immunity; timing range is adjustable to satisfy the timing needs of multiple match, only have a photoelectric sensor constitute simple in structure, be easy to carry, and multiple functional.
