By using the feedback control, the electrical inductance and the capacitor filtering; the direct current voltage is admitted to be input to the utility model. The utility model has the advantages of wide range and strong anti-interference capability. The protection device of the infrared veiling elevator door, which adopts the utility model can be suitable for elevators provided with direct current 24V. The power source is directly installed in an emitter and a receiver of the protection device of the elevator door, and a power source box is not needed.
Description
The utility model belongs to elevator door fender guard field of power supplies.
Infrared light curtain left door fender guard (or system) mainly is made up of infrared transmitter and infrared remote receiver at present.Projector and receptor are general respectively by wide 20～40mm, high 9～30mm, and the aluminium section bar of long 1700～2000mm is done casing, and emitting surface and receiving plane are adorned the red plexiglass or the red plastic of infrared light.Projector and receptor are contained in elevator cab door outer rim both sides respectively, so that have or not obstacle in the middle of emission infrared beam and the reception infrared beam detecting elevator door, have obstacle or anthropolith just to stop to close the door and reversing and open the door, and play the effect of protection people, thing.At present infrared light curtain left door fender guard (or system) adopt by～220V (or～110V) rectifying and wave-filtering, voltage stabilizing or adopt Switching Power Supply, volume can't be put into projector and receptor more greatly, can only do a power pack separately.As homemade ST-MES (32E type) microcomputer light curtain left door fender guard etc. a bigger power pack is just arranged.Also have can be directly with elevator control part direct current 24V power supply, but the translation circuit poor performance that elevator 24V uses to the infrared light curtain power supply, scope that can't stand the strong jamming of elevator start-stop and change of voltage is big, still need to be equipped with in addition～220V (or～110V) select for use to the power pack confession of direct current 24V.FCU0735 type light curtain and Britain Men Ke company 632 type light curtains as England Oxford company.Like this, make the power supply of infrared light curtain left door fender guard (or system) more too fat to move, not only improved cost, more than a failsafe link.
The purpose of this utility model provides a kind of elevator door fender guard power supply; the direct current 24V that its input voltage of the utility model power supply adopts elevator to provide; volume is small and exquisite; can put into the projector and the receptor of infrared light curtain left door fender guard respectively, need not to do in addition the bigger power pack of volume.
