Embodiment
For can the utility model be illustrated more clearly in, hereby lift preferred embodiment and coordinate graphic being described in detail as follows, shown in please refer to the drawing 1 to Fig. 4, for the button of sensing and detecting type in the same way 100 of the utility model one preferred embodiment, it includes body 10, circuit board 20, optical transmitting set 30, optical receiver 40 and a warning light 50.In the present embodiment, this body 10 is embedded into (not shown) in the control panel of an elevator.
This body 10 has shell 12, pedestal 14 and a supporting bracket 16.Wherein, this shell 12 is incorporated on this pedestal 14, this supporting bracket 16 be arranged at this shell 12 assemble with this pedestal 14 after accommodation space in.The centre of this shell 12 is provided with a light-permeable district 121, and this light-permeable district 121 can be engraved structure and formed, or a transparent plastic plate formed.In the present embodiment, this light-permeable district 121 is for being incorporated into the transparent plastic sheet on this shell 12, it can be provided with symbols such as including but not limited to English alphabet, numeral or pattern, for represent this button control the arrival object floor of elevator cage, or be unlatching or the closedown of elevator door.
This circuit board 20 is arranged in this supporting bracket 16, and it is electrically connected this optical transmitting set 30 and this optical receiver 40, and this optical transmitting set 30 is with this optical receiver 40 and adjacently arranges.Wherein, this optical transmitting set 30 has an exiting surface 32, and this optical receiver 40 has an incidence surface 42, and this exiting surface 32 and this incidence surface 42 are in the face of this light-permeable district 121.This optical transmitting set 30 is in order to send an infrared ray L, this infrared ray L penetrates to this body 10 outside through the light-permeable district 121 of this shell 12, when an object (the present embodiment is for the finger 200 of user) near but when not contacting this shell 12 surperficial, namely represent close to this optical transmitting set 30, generation is reflected and is received by this optical receiver 40 by the infrared ray L be obstructed, and now this optical receiver 40 will have issued a feedback signal according to this.Wherein, in order to ensure the generation opportunity of this feedback signal the best, induction is avoided to be remote object and to have occurred to control improperly, therefore this optical transmitting set 30 selected by the present embodiment, its infrared ray L produced has certain range to limit, generally speaking, 5mm is about for preferably induction range with the distance of object near the surface of this shell 12.
Shown in please refer to the drawing 5, this circuit board 20 includes signal processing circuit 22, timing circuit 24 and a control circuit 26.Wherein this feedback signal of sending in order to receive this optical receiver 40 of this signal processing circuit 22, this timing circuit 24 in this signal processing circuit 22, starts clocking capability simultaneously, records this feedback signal duration in time receiving this feedback signal; This control circuit 26, according to the length of 24 computing times of this timing circuit, sends a control signal to manipulate elevator cage lifting or the keying of elevator door in good time.That is this control circuit 26 enters the time length in the induction range of infrared ray L because of object (finger 200 of user), and produces different control command to manipulate elevator.
In the present embodiment, in first period of this control circuit 26 till this timing circuit 24 starts timing to one first setting time point, by output one first control signal, this first control signal is for the keying of the lifting or elevator door that control elevator cage, and actual functional capability is determined according to design.Aforementioned first period is for 2 seconds at the present embodiment, in other words, as long as object to enter in induction range and when being less than or equal to 2 seconds, all effectively can produce this first control signal.Again, this control circuit 26, in the timing course of this timing circuit 24, arriving between one second setting time point when exceeding this first setting time point (namely the 2nd second), will not output signal; This control circuit 26 after this timing circuit 24 timing exceedes this second setting time point, then exports one second control signal.Aforementioned second setting time point is for the 3rd second, in other words, when user determines to cancel previous control command (i.e. this first control signal), can reach object via the mode increasing the sensitive time (namely more than 3 seconds).Set between time point as the first setting time point to the second on a timeline, do not have the design that signal exports, object is that appropriateness separates the generation opportunity of this first control signal and this second control signal.Again, this first setting time point with this second set time point must comply with reality use situation and be adjusted.
This warning light 50 is electrically connected this circuit board 20, and this first control signal sent according to this control circuit 26 or this second control signal and produce the bright or lamp of lamp and go out.In the present embodiment, 2 seconds are less than or equal to when this finger 200 time stayed in induction range, and when making this control circuit 26 export this first control signal, this warning light 50 lights thereupon, this light-permeable district 121 of its light therethrough lighted and outside being revealed in, respond to successfully so that user knows.But, when user is for cancelling previous control command (i.e. this first control signal), only this finger 200 need be stayed in induction range again, and extend the time of staying more than 3 seconds, this control circuit 26 can be made to send this second control signal cancelling previous control command, now, this warning light 50 is by from lightened state, along with the output of this second control signal, lamp goes out, and user can know and successfully cancels previous control command.
Conclude above-mentioned, the real existing following listed advantage of the button 100 of sensing and detecting type in the same way of the present embodiment and effect:
1. compared to existing photoinduction formula elevator button, this in the same way sensing and detecting type button 100 be the button of insert structure, can avoid because of collision cause structural failure, promote useful life thus.
2. this in the same way sensing and detecting type button 100 can change the pattern in this light-permeable district 121 according to actual demand, and be able to this sensing and detecting type button 100 in the same way of application of diversity.And whether user also can appear light source in order to judge this light-permeable district 121, and learn this in the same way sensing and detecting type button 100 whether sensed or cancel.
3. user according to actual service condition, can cancel previous control command, avoids elevator cage to stay in nobody and takes advantage of the floor carried, extend the ride time of passenger.
The foregoing is only the better possible embodiments of the utility model, such as apply the utility model specification and the equivalence change for it of claim institute, ought to be included in the scope of the claims of the present utility model.
