When passenger-in-elevator's body part does not enter in the intersection region of escalator up and down, wherein any one described infrared receiver tube can continue to receive the infrared ray that corresponding described infrared emission tube sends, at this moment, described infrared receiver tube can not send any indicator signal to other unit of safety device 1.
When entering in the intersection region of escalator up and down at the body part the passenger-in-elevator, passenger-in-elevator's body part can stop the part infrared ray, the described infrared receiver tube that has does not so just receive the infrared ray that corresponding described infrared emission tube sends, at this moment, do not receive ultrared infrared receiver tube and just can send indicator signal to other unit of safety device 1.
Described signal amplification unit 11 links to each other with described detecting unit 10, receives described infrared receiver tube from described detecting unit 10 and sends indicator signal.For ease of identification and the processing of 12 pairs of described indicator signals of described control unit, usually need to amplify and nurse one's health indicator signal, so described signal amplification unit 11 can comprise amplifier and analog-to-digital conversion device, indicator signal is amplified and change.
Described control unit 12 links to each other with described signal amplification unit 11, exports control signal according to the signal in the described signal amplification unit 11; Indicator signal rear drive warning output unit 13 operations after the described control unit 12 identification conversion.
Described warning output unit 13 links to each other with described control unit 12, and the control signal of exporting according to described control unit 12 comes output alarm information, and described warning output unit 13 can adopt the mode of audio alert mode or display alarm.
In the present embodiment, particularly, described warning output unit 13 comprises speech player 14 and light-emitting diode display 15, namely adopts simultaneously the mode of audio alert mode and display alarm, to pass through alarming effect.
In the present embodiment, described speech player 14 when not receiving the driving signal of control unit 12, sounding not; Described speech player 14 when receiving the driving signal of control unit 12, output alarm voice, for example " danger! Please don't be close ", " please noting safety " or " please away from the scissors port area! " etc.
In the present embodiment, described light-emitting diode display 15 can show common safety instruction literal when not receiving the driving signal of control unit 12, for example, and demonstration " minding Your Head " or " taking care " etc.; Described light-emitting diode display 15 shows " danger when receiving the driving signal of control unit 12! Please don't be close! " and allow the frame fast blink of read-out.
In the present embodiment, adopt speech player 14 and light-emitting diode display 15 to point out simultaneously information warning, make the passenger-in-elevator not only can be eye-catching see information warning but also can hear information warning, so the utility model can improve alarming effect, so that the passenger-in-elevator recognizes danger, leave " scissors mouth " zone, greatly the assurance passenger-in-elevator's of degree personal safety.
In sum, a kind of safety device for escalator of the present utility model has following beneficial effect:
1, the utility model adopt the correlation infradred sensor to the intersection region of escalator up and down namely " scissors mouth " locate whether to have obstacle to detect, can effectively detect the passenger-in-elevator and enter " scissors mouth " zone, simultaneously send dangerous alarm signal to the passenger-in-elevator, so that the passenger-in-elevator leaves " scissors mouth " zone, the greatly assurance passenger-in-elevator's of degree personal safety.
2, the utility model enters " scissors mouth " when zone detecting the passenger-in-elevator, can adopt the double warning mode of voice and screen display, has higher alarming effect.
3, in addition, the utility model also has advantage simple in structure, easy for installation and with low cost.
