The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 1, the utility model comprise a controller 1; Two connecting cables 2, the aluminum alloy touch panel 3 of a band infrared transmitter, the aluminum alloy touch panel 4 of a band infrared remote receiver, two cover aluminum alloy touch panels are fixed and link gear 5.Its special feature is that two aluminum alloy touch panels are the Contact plate of mechanical type fender guard, is again the infrared transmitter and the receptor of electronic type infrared ray curtain, and they are connected on the controller by connecting cable.
In the process that elevator door cuts out, in case people or object appear in the elevator door plane of motion and cut off any a branch of infrared ray that forms between projector and the receptor, the touch panel that has receptor will be sent to this block information control capsule, provide enabling signal again by control capsule to apparatus for controlling elevator again, reaches the purpose that prevents to push passenger or article.If Infrared detection system breaks down or dead electricity can not detect the passenger that appears in the elevator door plane of motion or article or because similar passenger's finger and tiny article just in time appear at light curtain detection blind zone, elevator door cuts out continuing, until shelter touching aluminum alloy touch panel, this moment, the travel switch with the touch panel interlock can move, and the action of the trip switch can make apparatus for controlling elevator open the door again immediately.
As preferred controlling schemes, we carry out following coordination with the logical relation of photoelectricity, mechanical duplicate protection at design: 1, be in security consideration, no matter which kind of state Photodetection system is in, as long as mechanical touch panel device action is just exported enabling signal again.
2, must not when electricity when Photodetection system, be directly switch into mechanical touch panel protection, do not influence the safety that elevator normally moves, also guarantees the elevator operation simultaneously.
3, break down or when the light curtain is blocked by long-time continuous when Photodetection system; because this moment, photoelectric system can be in output enabling signal state all the time; stop using for a long time for avoiding elevator; system can delay time photoelectric system is excised; switch to the safety edge protection, do not influence the safety that elevator normally moves, also guarantees the elevator operation simultaneously.Simultaneity factor display light curtain fault reminds service personnel to repair as early as possible.
As shown in Figure 2, the utility model product is installed on the lift car.Simultaneously, as shown in Figure 3, connect travel switch and light curtain output signal and provide enabling signal again to apparatus for controlling elevator.Can realize machinery, photoelectricity double protection functions.
As Fig. 3 as can be seen, when not only having no talent or object shading light curtain, safety edge but also do not have when touched, output signal is in " conducting " state, and this signal condition allows elevator to continue to close the door; As people or object shading light curtain safety edge or any one side safety edge when touched, output signal is in " disconnection " state, this signal condition notice apparatus for controlling elevator is carried out the action of opening the door immediately.
From Fig. 3 also as can be seen, the output signal of light curtain is one pair of passive normally closed relay contact, thus must not when electricity when the light curtain, this contact is in " closure " state, and promptly the light curtain withdraws from control and the safety edge travel switch remains valid.If being blocked continuously, the light curtain arrives 15s; CPU in the control capsule will be judged as the normal operation that the light curtain breaks down or people's malice obstruction elevator is arranged; CPU also can make this contact be in " closure " state and switch to the safety edge protected mode, guarantees that elevator can continue operation safely, and buzzer call is reported to the police.
As shown in Figure 4, be the utility model CPU workflow diagram.
Compare with simple machine security touch panel, system provides duplicate protection, thereby has significantly reduced the probability that door knob hits passenger and object, and elevator seems safer, hommization has more also improved simultaneously the operating efficiency of elevator.
