In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiments of the present invention, for those of ordinary skills; Under the prerequisite of not paying creative work property, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the embodiment of indoor locating system of the present invention;
Fig. 2 is the structural representation that the coordinate setting of testee when surveyed area is arranged of the embodiment of indoor locating system of the present invention.
Embodiment
For making the present invention be more prone to understand, below in conjunction with accompanying drawing the present invention is done further elaboration, but the embodiment in the accompanying drawing does not constitute to any restriction of the present invention.
A kind of indoor locating system; As shown in Figure 1, comprise that two infrared reception bars with a plurality of infrared remote receivers 11 10, four timesharing send the infrared transmitter 50 of infrared detection signal and the positioning treatment apparatus that is electrically connected with said infrared remote receiver 11 (identifying among the figure); Article two, said infrared reception bar 10 is oppositely arranged; Four said infrared transmitters 50 lay respectively at the two ends of two said infrared reception bars 10; Said infrared reception bar 10 is positioned at same plane with said infrared transmitter 50; The infrared signal that two the said infrared transmitters 50 in said infrared remote receiver 11 reception opposites send, the line of the opposite endpoint of two said infrared reception bars 10 and two said infrared reception bars 10 surround a surveyed area; Said positioning treatment apparatus (among the figure sign) confirms to be positioned at the coordinate of the testee 30 of said surveyed area according to the situation of the reception infrared signal of the position coordinates of the position coordinates that is arranged at the said infrared transmitter 50 in it, said infrared remote receiver 11 and said infrared remote receiver 11.
Infrared signal is sent in infrared transmitter 50 timesharing that are positioned at infrared reception bar 10 two ends of indoor locating system of the present invention, and infrared remote receiver 11 receives the infrared signal of two infrared transmitters, 50 transmissions that are positioned at the opposite.When people or object entering surveyed area; Block the infrared signal of infrared transmitter 50 emissions; Make at least two infrared remote receivers 11 of the infrared reception bar 10 of an end can not receive infrared signal, positioning treatment apparatus (among the figure sign) confirms to be positioned at the coordinate of the testee 30 of said surveyed area according to the situation of the reception infrared signal of the position coordinates of the position coordinates of the infrared transmitter in it 50, infrared remote receiver 11 and infrared remote receiver 11.
Indoor locating system of the present invention is confirmed object under test or people's position through the infrared transmitter 50 emission infrared signals that are positioned at infrared reception bar 10 two ends; Simple in structure and bearing accuracy is high; Do not need as prior art, on object under test or people, to install or wear sender unit, therefore indoor locating system of the present invention has advantage easy to use.And, because indoor locating system of the present invention adopts infrared remote receiver 11 and infrared transmitter 50, therefore, satisfying under the condition of identical bearing accuracy, the cost of indoor locating system of the present invention is very low.
Preferably, two said infrared reception bars 10 are parallel to each other, and indoor at rectangle or rhombus like this can increase the area of surveyed area.Certainly, infrared reception bar 10 also can be selected to be not parallel to each other mutually according to the shape of surveyed area.
Preferably, infrared reception bar 10 is a straight line, and promptly surveyed area is a rectangle or rhombus.Surveyed area is set to a rectangle in rectangular chamber, can increase the area of surveyed area.Be set to a rhombus at the indoor surveyed area of rhombus, can increase the area of surveyed area.Certainly, also can infrared reception bar 10 be set to curve, like circular arc etc. according to the indoor concrete shape and the specific requirement of surveyed area.In some circles or two sides is the indoor of circular arc, and infrared reception bar 10 is set to circular arc, can increase the area of surveyed area.
As shown in Figure 2, existing surveyed area with rectangle is an example, and the method for the coordinate of confirming testee 30 or people position is described:
Positioning treatment apparatus (not identifying among the figure) can be initial point with the coordinate of upper left corner infrared transmitter 50; Coordinate is (0; 0), be the longitudinal axis with the place straight line of the infrared reception bar 10 in the left side, the straight line at the line place of the relative end points of two infrared reception bars 10 is a transverse axis.The length that positioning treatment apparatus (not identifying among the figure) internal memory contains two infrared reception bars 10 is L, and the wire length of the opposite endpoint of two infrared reception bars 10 is H.As testee 30 or people during at surveyed area; Being positioned at the infrared signal that upper left corner infrared transmitter 50 sends is blocked by testee 30; H, infrared remote receiver 11 n) make the coordinate that is positioned at the infrared reception bar 10 in the right for (can not receive the infrared signal that upper left corner infrared transmitter 50 sends; Be positioned at the infrared signal that the infrared transmitter 50 in the upper left corner sends and blocked, make the coordinate that is positioned on the infrared reception bar 10 in the right be (H, m) infrared signal sent of some position infrared remote receiver 11 infrared transmitter 50 that can not receive the upper left corner by testee 30.The situation that all infrared remote receivers 11 will receive infrared signal feeds back to positioning treatment apparatus (not identifying among the figure); Positioning treatment apparatus (not identifying among the figure) can draw following two formula according to geometric figure, thereby calculates testee 30 or people's coordinate exactly.
Two formula that draw according to geometric figure:
Can draw by formula (1), (2):
In like manner, when initial point is arranged on other positions, also can calculate testee 30 or people's coordinate according to mathematical method.So just can realize the moving object location of whole surveyed area.
Certainly, when the reception bar is curve, also can confirm the coordinate of testee 30 positions, here repeat no more through geometric formula.
The above is a preferred implementation of the present invention; Certainly can not limit the present invention's interest field with this; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; Can also make some improvement and change, these improvement and change also are regarded as protection scope of the present invention.
