Description
Technical field
The present invention relates to a kind of infrared module, refer to be used in the infrared module of judgment object position especially.
Background technology
Detecting the position of object with infrared ray, is ultrared a kind of daily use.Automobile position sensing apparatus of reversing radar of vehicle, mechanical parking etc. for example.If will on vast plane, detect the position of object more accurately, then need many groups infrared transmitter and infrared inductor.
See also Fig. 1, Fig. 1 is the synoptic diagram of known technology in order to the infrared module 2 of detecting one dimension position.It is that relative both sides (and arranged on left and right sides among the figure) in a plane are provided with many group infrared transmitter 4 and infrared inductors 6, then with scanning mode, these infrared transmitter 4 produce infrared ray Er in regular turn, and receive this infrared ray Er in regular turn by the infrared inductor 6 of opposite side correspondence.
When the infrared ray Er signal of being launched when one group of infrared transmitter 4 is wherein covered by an object 8, same group infrared inductor 6 is because respond to less than infrared ray Er signal, so judge that having an object 8 on this one dimension path (path that infra-red signal is walked) exists, and then utilize the relativeness of coordinate, can demonstrate the one dimension position of object 8.
Yet, the mode of known utilization scanning, once only there are one group of infrared transmitter, 4 emission infrared ray Er to allow the infrared inductor 6 of opposite side respond to, therefore, the reaction velocity of whole infrared module 2, along with the quantity of infrared inductor 6 is reacted more greatly, this is the design of pattern for connecting that known signal transmission cooperation scans.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of infrared module that is used in the judgment object position, can come the position of perceptual object on the plane more accurately, to improve the problems referred to above with reaction velocity faster.
For solving the problems of the technologies described above, the present invention proposes a kind of infrared module, this infrared module comprises: a plurality of infrared transmitter, described infrared transmitter produces a plurality of infrared rays simultaneously; A plurality of infrared inductors, an infrared transmitter in the corresponding described infrared transmitter of each infrared inductor difference in the described infrared inductor, the infrared ray that described infrared inductor receives pairing infrared transmitter respectively and produced is to produce a plurality of messages; And a plurality of signal line, each signal line in the described signal line is connected in each infrared inductor in the described infrared inductor, and this signal line is in order to transmit the message that this infrared inductor produces.
Preferably, this infrared module more comprises a processor, and it connects described signal line, in order to receive and to handle the message from described signal line.
Preferably, this infrared module is in order to respond to the position of an object in a plane.
Preferably, this processor is according to the interruption of message that this infrared inductor produces, to differentiate the position of this object in this plane.
Therefore, the present invention is used in the infrared module of judgment object position, utilize signal transmission manner in parallel, make these infrared transmitter produce a plurality of infrared rays simultaneously, and be different from the signal series connection transmission mode of known technology with scanning, the present invention is the interruption of perception message simultaneously, so can come the position of perceptual object on the plane with reaction velocity faster.In addition, because infrared module of the present invention uses signal transmission manner in parallel, so when the message of adjacent a plurality of infrared inductors is all interrupted, further can extrapolate the littler object space of error rate with mean value method.

Embodiment
See also Fig. 2, Fig. 2 is the synoptic diagram of infrared module 30 of the present invention.The invention relates to a kind of infrared module 30, infrared module 30 is in order to respond to an object 50 in the position on a plane 52.Infrared module 30 comprises a plurality of infrared transmitter 32, a plurality of infrared inductor 34, a plurality of signal line 36 and a processor 38.
These infrared transmitter 32 produce a plurality of infrared rays 40 simultaneously.An infrared transmitter 32 in each infrared inductor 34 respectively corresponding these infrared transmitter 32 in these infrared inductors 34, and become one group one group infrared transmitter 32 and infrared inductor 34, these infrared inductors 34 receive respectively correspond to the infrared ray 40 that same group infrared transmitter 32 is produced, to produce a plurality of messages simultaneously.
Each signal line 36 in these signal line 36 is connected in each infrared inductor 34 in these infrared inductors 34, the message that signal line 36 is produced in order to transmission infrared inductor 34.
Further specify, each organizes corresponding infrared transmitter 32 and infrared inductor 34 is to arrange the relative both sides that are arranged at a plane 52.So, if only 52 arranged on both sides is provided with many corresponding infrared transmitter 32 of group and infrared inductor 34, the position that only can record the one dimension direction in the plane.
See also Fig. 3, Fig. 3 is that the present invention passes through the synoptic diagram that many induction message embodiment illustrate computing method.When adjacent infrared inductor 34 message that produces was all interrupted, processor 38 can be asked for the mean value of these 34 interpretation positions of adjacent infrared inductor, with differentiate object 50 in the plane 52 position.
For example, there is an object 50 to interdict two groups of adjacent infrared rays 40 simultaneously in certain one dimension direction, therefore there is two (group) adjacent infrared inductor 34 message that produces all to interrupt, also have one group of infrared inductor 34 message that produces to interrupt with its orthogonal directions, 52 coordinate position is (52,182) and (52 in the plane so originally should be corresponding go out object 50,184), if calculation process in addition maybe might not be judged as 2 objects 50, or might interpretation not come out.Calculate with mean value, coordinate position is (52,183), can more accurately judge the position of object 50 in coordinate, the situation of having avoided processor 38 to handle.If known signal series connection transmission mode, can't learn simultaneously that promptly two (group) adjacent infrared inductor 34 message that produces all interrupts, so also can't ask for its mean value with scanning.
Therefore, be used in the infrared module 30 of judgment object 50 positions by the present invention, utilize signal transmission manner in parallel, make these infrared transmitter 32 produce a plurality of infrared rays 40 simultaneously, and be different from the signal series connection transmission mode of known technology with scanning, the present invention is the interruption of perception message simultaneously, so can come the position of perceptual object 50 on plane 52 with reaction velocity faster.
With example of the present invention,, adopt the processor 38 of 16bits if having 16 groups of infrared inductors 34, all messages once can dispose, and slower with the speed of scanning signal series connection transmission mode, handle 16 times, the time that is spent is 16 times of the present invention.
In addition, because infrared module of the present invention 30 uses signal transmission manner in parallel, so when the message of adjacent a plurality of infrared inductors 34 is all interrupted, further can extrapolate the littler object of error rate 50 positions with mean value method.
The above detailed description of preferred embodiments is to wish to know more the feature and spirit of describing the present invention, and is not to come category of the present invention is limited with above-mentioned disclosed preferred embodiment.On the contrary, its objective is that hope can contain in the category of claim of being arranged in of various changes and tool equality institute of the present invention desire application.
