Close function, additionally it is possible to identify the moving direction of object.
To achieve the above objectives, the technical solution adopted in the utility model is：A kind of direction automatic recognition system, including control
Device processed, it is characterised in that also include two groups of sensing elements being connected respectively with controller signals, the controller can be according to connecing
The moving direction of object is identified the signal of the sensing element received.
Preferably, every group of sensing element includes infrared-emitting diode and infrared integrated receives head, the infrared hair
Penetrate diode and rear outer integration receives head and is connected with controller signals.
Compared with prior art, the utility model has the advantages that：
1) moving direction of the objects such as the human hand in identification range can be identified for the system, and then realize to it
Its equipment travel direction controls, and the control of more than current on and off, can be realized by gesture etc. to more equipment
Control；
2) system is when judging that human hand is whether in identification range, by two kinds of feelings of transmission signal and non-transmission signal
Judgement is identified under condition, reduces the probability of erroneous judgement；And ensure the correctness of recognition result by multiple authentication, enter one
Step reduces erroneous judgement.
Brief description of the drawings
Fig. 1 is the control principle drawing according to a preferred embodiment of the present utility model
Embodiment
Describe to be used to disclose the utility model so that those skilled in the art can realize the utility model below.Retouch below
Preferred embodiment in stating is only used as illustrating, it may occur to persons skilled in the art that other obvious modifications.
Direction automatic recognition system, including controller 1 and two groups of sensing elements, two groups of sensing elements are respectively to sense member
Part 21 and sensing element 22, sensing element 21 and 22 are connected with the signal of controller 1, and controller 1 can be according to from sensing element
21 and 22 signals received identify the movement of action that people waves or other objects.
Specifically, sensing element 21 includes an infrared-emitting diode 211 and an infrared integrated receives first 212,
Sensing element 22 includes an infrared-emitting diode 221 and an infrared integrated receives first 222, on the one hand controller 1 is controlled
Infrared-emitting diode 211 and 221 processed sends infrared pulse signal, on the one hand detects infrared integrated reception first 212 and 222 and connects
Receive the infrared pulse signal being reflected back.
The identification hand of the system or the method for other objects are as follows：Illustrated with sensing element 21, controller 1 controls infrared
The transmitting burst length of emitting diode 211 (the transmitting burst length refers to the duration of individual pulse)；In the transmitting burst length
Interior, infrared-emitting diode 211 launches infrared pulse signal, if infrared integrated, which receives first 212, receives signal, is labeled as
flag1；Outside the transmitting burst length, i.e., when infrared-emitting diode 211 is without transmitting infrared pulse signal, if infrared by one
Bodyization receives first 212 and is not received by signal, labeled as flag2；If flag1 and flag2 are true, controller 1 is determined as
Hand or other objects have been recognized, and has made corresponding control, if flag1 and flag2 wherein at least one is false, specifically
Ground, if flag1 is false, flag2 is true, i.e., when infrared-emitting diode 211 launches infrared pulse signal, infrared integrated
Receiving first 212 does not have reception signal, and when infrared-emitting diode 211 is without transmitting infrared pulse signal, infrared integrated connects
Receive first 212 and also do not receive signal, illustrate there is no gesture or object in the range of it can identify；If flag1 is true,
Flag2 is false, i.e., when infrared-emitting diode 211 launches infrared pulse signal, infrared integrated receives first 212 and have received
Infrared pulse signal, when infrared-emitting diode 211 is without transmitting infrared pulse signal, infrared integrated receives first 212
Infrared pulse signal is have received, the infrared pulse signal for illustrating to receive is not from infrared-emitting diode 211, it may be possible to
The signal that other infrared equipments are sent；If flag1 is false, flag2 be it is false, now when infrared-emitting diode 211 launch it is red
During outer pulse signal, infrared integrated receives first 212 and is not received by signal, when infrared-emitting diode 211 is red without launching
During outer pulse signal, infrared integrated receives first 212 and but have received signal, and such a situation is also likely to be other do occurred
Disturb source.In the case of for flag1 and flag2, one of them is false, controller be judged to not having in identification range gesture or
Object.
In order to ensure the accuracy of identification, controller 1 can verify repeatedly to flag1 and flag2, i.e. controller 1 can be with
Cyclically control infrared-emitting diode 211 to launch pulse signal and stop transmitting infrared pulse signal, to flag1 and flag2
After carrying out multiple authentication, if flag1 and flag2 are largely true or from flag1 and flag2 after being for the first time true
It is true after certain number, illustrates that there is hand or other objects in the range of identification.Specifically, flag1 and flag2 exist
Repeatedly verify when be genuine number or for the first time be very after how many times be that very can set.Also, because controller 1 controls
The frequency that transmitting infrared pulse signal is launched and stopped to infrared-emitting diode 211 is very high, therefore, even if object is mobile,
Also it can ensure to receive the signal of certain number.
Also, the recognition methods that the recognition methods and sensing element 21 that sensing element 22 moves to object are moved to object is complete
It is complete the same, using the above method.Wherein, the infrared-emitting diode 211 and 212 and infrared integrated receive first 212 He
222 use prior art, are no longer described in detail herein.
The direction recognizing method of the system is as follows：Two sensing elements 21 and 22 are installed, and make infrared emission two
The infrared pulse direction of the launch of pole pipe 211 and 221 is parallel to each other, it is impossible to overlaps, while describes for convenience, it is assumed that sensing element
21 are arranged on the right of sensing element 22；When controller 1 is firstly received the signal of sensing element 21, sensing member is then received
The signal of part 22, illustrate that object or hand move from right to left；When controller 1 is firstly received the letter of sensing element 22
Number, the signal of sensing element 21 is then received, illustrates that object or hand move from left to right；When controller 1 persistently connects
Sensing element 21 or sensing element 22 signal of one of them are received, i.e. human hand or object rests on sensing element 21 or 22
Identification region in, now controller 1 exports "signal for " stop ", can be motor stalls, or game over etc..When
So, sensing element 21 and 22 can left and right set, can also be setting up and down, can be with the horizontal the setting of other angles.
The controller 1 can be single-chip microcomputer of the prior art, no longer be described in detail herein.
The advantages of general principle of the present utility model, principal character and the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply principle of the present utility model, the utility model also has respectively on the premise of the spirit and scope of the utility model is not departed from
Kind changes and improvements, these changes and improvements are both fallen within claimed the scope of the utility model.The requires of the utility model
Protection domain defined by appended claims and its equivalent.
