Abstract
A kind of elevator inlay door lock loop that detects is by the detecting device of short circuit, wherein: connect two sampling wires at the layer door lock switch contact place of every layer respectively and detect change-over panel, described detection change-over panel is connected with the calling plate in the elevator calling case of every layer, and described calling plate is controlled by apparatus for controlling elevator.Present invention employs and automatically detect door lock safety return circuit by the method for short circuit by apparatus for controlling elevator, completely avoid layer door lock safety return circuit by short circuit, thus the elevator accident avoiding safety return circuit to be caused by short circuit occurs, improve the safety performance of elevator.
Description
Technical field
The present invention relates to the safety testing field of elevator electrical, particularly a kind of elevator inlay door lock loop that detects is by the detecting device of short circuit.
Background technology
In order to protect the safety of personnel, elevator needs to detect gate and the layer door switch that be installed on each layer, and only have after the gate of elevator and all layer doors are all closed, elevator could run, and the elevator safety specification of various countries has all made strict regulation to this.
Elevator is all provided with layer door in each gangway, when elevator cage operation is to institute's arrival floor, moves layer door lock open layer door by gate door knife-band, for passenger or goods turnover elevator.Elevator landing door lock is that elevator door safety is protected and a vitals indispensable in door opener.In normal use procedure, layer door lock is main composition by mechanical latch hook and electrical contact.When layer door locking states, latch hook closes, and the electrical contact of layer door lock combines, and layer door lock electrical safety loop is connected, and elevator can safe operation.Work as door-lock opening, electrical contact disconnects, then door lock safety return circuit disconnects, and elevator cannot run.
At some in particular cases, if elevator service personnel is in maintenance process, conveniently overhaul elevator and by certain layer or the safety return circuit short circuit of layer door lock of multilayer, and for example indivedual layer layer door lock safety return circuit fault and cause short circuit phenomenon.When not removing the safety return circuit shorting stub of short circuit door lock or door lock safety return circuit short circuit fault does not get rid of, elevator at nominal conditions, can run, that is, when layer door is under the situation be opened, after door lock safety return circuit short circuit, elevator still can normally run.Can safety misadventure be caused like this, cause the grievous injury of personnel and property.Also there is no a kind of apparatus and method of better detection layers door lock safety return circuit short circuit at present, be all by artificial memory and use the method for some external prompt to eliminate short circuit situation, if carelessness just causes short circuit loop exist and cause lift running safety hidden danger, can not ensure that relieving layer door lock safety return circuit is by the situation of short circuit completely.
The accident caused by short circuit in order to avoid layer door lock safety return circuit occurs, and invents a kind of elevator inlay door lock loop that detects and is solved the problem by the detecting device of short circuit.
Summary of the invention
In order to overcome the above-mentioned shortcoming of prior art, the object of this invention is to provide and automatically detect door lock safety return circuit by a kind of elevator inlay door lock loop that detects of short circuit by the detecting device of short circuit by apparatus for controlling elevator.
The technical solution adopted for the present invention to solve the technical problems is: a kind of elevator inlay door lock loop that detects is by the detecting device of short circuit, wherein: connect two sampling wires at the layer door lock switch contact place of every layer respectively and detect change-over panel, described detection change-over panel is connected with the calling plate in the elevator calling case of every layer, described calling plate is controlled by apparatus for controlling elevator, detects electric loop as follows by the method for short circuit:
Described sampling wire wherein voltage to ground lower than 30% of safety return circuit voltage, judge that this layer (n layer) door switch disconnects, now this layer or this layer under the sampling wire voltage to ground of floor (m layer) all higher than 80% of safety return circuit voltage, judge that the door switch of m layer does not disconnect, safety return circuit is by short circuit, described apparatus for controlling elevator sends breakdown signal and failure code, and elevator can not run, and artificially must remove this fault.
As a further improvement on the present invention: described door switch forms loop by two sampling wires with detection change-over panel, lower than 30% of safety return circuit voltage, described sampling wire voltage to ground wherein judges whether door lock is opened.
Compared with prior art, the invention has the beneficial effects as follows: have employed and automatically detect door lock safety return circuit by the method for short circuit by apparatus for controlling elevator, completely avoid layer door lock safety return circuit by short circuit, thus the elevator accident avoiding safety return circuit to be caused by short circuit occurs, improve the safety performance of elevator.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
The present invention is further described for existing accompanying drawings and embodiment:
With reference to figure 1, a kind of elevator inlay door lock loop that detects is by the detecting device of short circuit, wherein: connect two sampling wires at the layer door lock switch contact place of every layer respectively and detect change-over panel, described detection change-over panel is connected with the calling plate in the elevator calling case of every layer, described calling plate is controlled by apparatus for controlling elevator, detects electric loop as follows by the method for short circuit:
Described door switch forms loop by two sampling wires with detection change-over panel, if namely described layer door lock is in locking states, layer door lock switch contact combines, layer door lock electrical safety loop is connected, and now described sampling wire voltage to ground is all higher than 80% of safety return circuit voltage; Otherwise described sampling wire voltage to ground is wherein lower than 30% of safety return circuit voltage.
When Elevator landing opens the door, pass the door lock action situation of every one deck back apparatus for controlling elevator by calling plate by method recited above, control system judgment criterion is as follows:
1. the floor door lock of door-opened elevator and following floor door lock thereof all disconnect, and door switch is working properly, without short circuit phenomenon.
2. the floor door lock of door-opened elevator close or its following floor wherein one deck (or multilayer) door lock close, door switch short circuit phenomenon has been described.Described apparatus for controlling elevator sends breakdown signal and failure code, and elevator can not run, and artificially must remove this fault.
Case study on implementation one:
When elevator n layer opens the door, described n layer door lock switch disconnects, now sample wire wherein voltage to ground higher than 80% of safety return circuit voltage, judge that n layer safety return circuit is by short circuit, described apparatus for controlling elevator sends breakdown signal or failure code, elevator can not run, and artificially must remove this fault.
Case study on implementation two:
When elevator n layer opens the door, described n layer door lock switch disconnects, now the sampling wire of n-1 layer wherein voltage to ground higher than 80% of safety return circuit voltage, judge that n-1 layer safety return circuit is by short circuit, described apparatus for controlling elevator sends breakdown signal or failure code, elevator can not run, and artificially must remove this fault.
In sum, after those of ordinary skill in the art reads file of the present invention, make other various corresponding conversion scheme according to technical scheme of the present invention and technical conceive without the need to creative brainwork, all belong to the scope that the present invention protects.
