Embodiment
Suppose that a pair of infrared tube sends and receives the required time of infrared signal is to be T1 in the sampling time; After treating that the receiving tube circuit is stable; Down a pair of infrared tube is redispatched and receiving infrared-ray signal, wait for the stable time of circuit in other words infrared signal be T2 from a pair of infrared tube to switching time of a pair of infrared tube down.Through the receiving tube circuit waveform is analyzed, T1 is about the 2-3 microsecond, and T2 is about 60 microseconds, and hence one can see that, and switching time, T2 was much larger than sampling time T1, and it is that switching time is long that barrier is located the major reason of a specified duration that expends time in.Consider switch be one must through process, can't evade and also being difficult to the shortening time, the inventor has visualized this method from the parallel angle of switching of a plurality of infrared tubes.Below in conjunction with accompanying drawing illustrated in detail infrared ray localization method of the present invention.
Infrared ray localization method of the present invention, as shown in Figure 1, comprise following two steps:
Step 1, select n power valve from each expelling plate, choose m power valve altogether, said m is the number of expelling plate, and said n is the numbering of power valve on each expelling plate;
Step 2, a m said power valve transmitted in sequence infrared ray; Return last step after the battery has fired; The value of said n adds l, the value until said n of circulating successively greater than each expelling plate on the number of power valve, said l is greater than 0 and less than the integer of power valve number on each expelling plate.
Above-mentioned steps is based upon on the following hypothesis basis: the expelling plate to be scanned and the number of dash receiver are m, and the power valve on each expelling plate is numbered, and numbering representes with parameter n, the value of n be from 1 to each expelling plate the number of power valve.
Step 1 is chosen one group of power valve from expelling plate; Concrete does, from m expelling plate, respectively chooses a power valve, obtains m power valve; This m power valve is parallel to be chosen; Walking abreast and choosing m the time that power valve spent is identical with the time of choosing 1 power valve separately, and therefore, the consuming time of step 1 is T2.For fear of because the little appearance of receiving tube spacing receives the problem of disturbing, the numbering of the power valve of choosing from each expelling plate is identical, and promptly the value of the numbering n of m selecteed power valve is identical.
An above-mentioned m power valve is chosen simultaneously, but they launch infrared signal simultaneously, but emission successively; After promptly going up a power valve emission infrared signal; At a distance from a period of time, next power valve is launched infrared signal again, successively until the equal battery has fired of a selected m power valve.Then get into the next round emission; Mode according to step 1 is chosen a power valve that is numbered n again from each expelling plate, just the value of n has added l at this moment, so circulation; Last power valve battery has fired on each expelling plate has so far just been accomplished the one-time positioning emission.The value of above-mentioned l is more than or equal to 1 integer smaller or equal to power valve number on each expelling plate, can freely set as required.When the size of barrier hour, the value of l is suitable little, otherwise possibly locate less than barrier, when the barrier size was big, the value of l was suitable big, can reduce positioning time like this.Aforementioned the separated time also can freely be set; As a preferred embodiment, two power valve Transmission Time Interval are that a pair of infrared tube is from being transmitted into the time of reception, i.e. T1; Mean the emission of a pair of infrared tube receive finish after, and then a pair of infrared tube is launched reception down.Like this, the same time has only a receiving tube at receiving infrared-ray signal, therefore, need not increase signal wire.If according to traditional localization method, power valve is selected in serial, serial emission infrared signal, and accomplishing a barrier location required time is the number that (mT1+mT2) multiply by power valve on each expelling plate.After adopting this method; The parallel power valve of selecting, serial emission infrared signal, as shown in Figure 3; Horizontal ordinate is represented the time; The parallel time T 2 of selecting m power valve of big waveform representative, the time T 1 that receiving infrared-ray signal is once launched in the small form representative is represented m small form with 14 small form among the figure; I.e. time of taking turns of (mT1+T2) expression m each self-emission of expelling plate infrared signal then, accomplishing a barrier, to locate required time be the number that (mT1+T2) multiply by power valve on each expelling plate.
