Description
Technical field
The utility model relates to elevator safety control field, especially relates to a kind of energy saving type elevator light curtain that automatically can cut off light curtain transmitter power in unnecessary.
Background technology
Automatic door of elevator is when closing the door, and in order to prevent extruding passenger and object, all can install safety device, common safety device has two kinds: 1, mechanical safety shoe; 2, Electronic Infrared linear light curtain.
The protection philosophy of mechanical safety shoe is in the process of elevator door closedown; the aluminum alloy touch panel be arranged on elevator the right and left gate is touched if any passenger or object; travel switch action, this action can provide an enabling signal to apparatus for controlling elevator, and elevator door is reopened.Obviously, mechanical safety shoe is a kind of fender guard of contact.But because it installs inconvenience, speed of response is slow, high in cost of production shortcoming, gradually replace by Electronic Infrared linear light curtain.Electronic Infrared linear light curtain, as a kind of New Product, has and improves elevator operating efficiency, installs and uses the advantages such as simple and convenient, fast response time.Electronic Infrared linear light curtain is a kind of contactless fender guard, the protection philosophy of Electronic Infrared linear light curtain is in the process of elevator door closedown, by being arranged on receptor on elevator the right and left gate and projector, the high-velocity scanning of recycle many groups infrared emission and receiving element, detection appears in elevator door plane of motion with or without object or person in protected zone, if occur people or thing, infrared ray can be blocked, controller will provide an enabling signal to apparatus for controlling elevator, this enabling signal is generally the low and high level signal of passive relay signal or aerotron output, elevator door is reopened.By the above-mentioned introduction to these two kinds of fender guards; can find out no matter be traditional mechanical safety shoe; or Electronic Infrared linear light curtain, only has the outdevice (travel switch, relay, aerotron) when them normal, just can play the effect of protection.Just do not have protective effect when arbitrary outdevice goes wrong, folder people insert event may occur.Close when elevator runs up and down at elevator door and circulate in the same old way and transmit and Received signal strength, power valve, adoptor to work under high-frequency impulse level easily damage always and waste electricity again.
State Intellectual Property Office of the People's Republic of China disclosed on 07 24th, 2013 the patent documentation that Authorization Notice No. is CN203079495U, title is elevator intelligent light curtain, its technical scheme is: comprise two light curtain main bodys, infrared transmitter and receptors, each light curtain main body is respectively equipped with many group infrared transmitters and many receivers, each light curtain main body at least installs one group of children's limit for height opto-electronic pickup and one group of children detects opto-electronic pickup, often organize opto-electronic pickup and be arranged in parallel by two opto-electronic pickups respectively and form sensor for countering.This scheme is after elevator door cuts out, and power valve, adoptor are still in work, there is the problem of energy dissipation.
Summary of the invention
The utility model elevator door mainly solved existing for prior art cuts out later power valve, adoptor still in the technical matters of work, waste electric energy etc., there is provided a kind of makes power valve and adoptor quit work after elevator door cuts out, economize energy, improves the energy saving type elevator light curtain in light curtain service life.
The utility model is mainly solved by following technical proposals for above-mentioned technical matters: a kind of energy saving type elevator light curtain, comprise controller, light curtain projector, light curtain receptor and two travel switches, the signal control port of described light curtain projector is connected with controller; The three-prong of the first travel switch connects power supply VCC, and the 4th pin connects the power supply port of light curtain projector, the first pin and the second pin unsettled; First pin of the second travel switch and three-prong are all connected to the signal input port of controller, and the second pin is connected to power supply VCC, and the 4th pin connects the signal output port of light curtain receptor; First travel switch and the second travel switch under non-pressed state, three-prong and the 4th pin conducting, under effective pressed state, the first pin and the second pin conducting; Described controller is connected to elevator master controller; The closing face of the left car door of elevator has the first shrinkage pool, and the first travel switch is arranged in the first shrinkage pool, and the closing face of the right car door of elevator is provided with the first striker with the first pit correspondence position; The closing face of the right car door of elevator has the second shrinkage pool, and the second travel switch is arranged in the second shrinkage pool, and the closing face of the left car door of elevator is provided with the second striker with the first pit correspondence position.
The plane that elevator cab door is provided with light curtain projector or light curtain receptor is closing face, and time elevator door cuts out, closing face is bonded to each other.When elevator cab door is opened time, light curtain projector is communicated with power supply, light curtain receptor is also communicated with controller, and light curtain projector launches infrared light under control of the controller, and light curtain receptor exports corresponding signal to controller according to whether receiving infrared light.When elevator door cuts out time, the first striker inserts in the first shrinkage pool and presses the first travel switch, and the three-prong of the first travel switch and the 4th pin are disconnected, namely disconnects between light curtain projector and power supply, light curtain projector quits work; Second striker inserts in the second shrinkage pool and presses the second travel switch simultaneously, the three-prong of the second travel switch and the 4th pin are disconnected, first pin and the second pin conducting, namely light curtain receptor quits work, and the signal input port of controller still receives high level.This scheme is applicable to the situation that light curtain receptor has some or all of output low level when not receiving infrared signal, if light curtain receptor has, some or all of what export when not receiving infrared signal is high level, then should by the second pin ground connection of the second travel switch.Travel switch is arranged in shrinkage pool and can prevents from being touched causing elevator controlling not normal by mistake.
As preferably, the distance on described first shrinkage pool and the second shrinkage pool and car door top is all less than 20 centimetres.First shrinkage pool and the second shrinkage pool should be arranged on higher position, prevent from being touched by mistake.
As preferably, also comprise several LED, the photosensitive receiving tube one_to_one corresponding of described LED and light curtain receptor, LED is connected with controller; LED is arranged on elevator door.
When there being certain photosensitive receiving tube of light curtain receptor not receive infrared signal, light corresponding LED, user can learn light-emitting tube or photosensitive receiving tube fault when finding that blocking-up does not still still have LED bright, avoid the elevator taking potential safety hazard, maintainer can also be reminded to find fault as early as possible and place under repair.
The beneficial effect that the utility model brings is, can close at elevator and quit work with relief light curtain projector and light curtain receptor, economize energy, extend the service life of elevator light curtain, only need slightly to make an amendment can realize effect to the circuit of conventional elevator light curtain, do not relate to the change to controller, control program, with low cost; User can be allowed to understand the situation of elevator light curtain in time, improve safety, be convenient to safeguard.
