Abstract

The utility model discloses a controller with the function of door lock short circuit prevention. The controller comprises a hoistway door lock signal input port, a car door lock signal input port, a logic control module, a maintenance relay output module, a door lock relay output module, a maintenance signal output port and a door lock signal output port, wherein the hoistway door lock signal input port and the car door lock signal input port are arranged at one end of the logic control module, the maintenance relay output module and the door lock relay output module are arranged at the other end of the logic control module, the maintenance relay output module is connected with the maintenance signal output port, and the door lock relay output module is connected with the door lock signal output port. According to the controller, that whether the door lock is in short circuit or not can be detected, and the elevator which is out of the short circuit can operate regularly; once that the door lock is in short circuit is detected, the maintenance return circuit can be switched off immediately, the elevator is in the maintenance state automatically, and maintenance personnel or passengers are reminded that the elevator cannot be used normally, so that the safety of the elevator can be increased.

Description

A kind of anti-door lock short circuit controller

Technical field

The utility model relates to a kind of lift appliance, is specifically related to a kind of anti-door lock short circuit controller.

Background technology

In current life, elevator is ubiquitous, and the safety of elevator also becomes the focus of concern.Add up from the casualty accident of elevator, the reason of the short circuit accident of elevator hall's door lock has accounted for 50%.Door lock of elevator control loop is the electric loop that the door lock of all doors is together in series, and whether is normally used for detecting gate switch, and when door is in the time that abnomal condition is opened, electric loop disconnects, and control system detects signal, and at this moment elevator can not move.And door lock is operation parts the most frequently in elevator, and contact on door lock is in the moment of contact, and under the effect of electric current, door lock contact is easy to damage.In the situation of some maintainer's general ideas, for maintenance facilitated short circuit damage door lock, but maintenance after do not have to remove timely shorting stub, cause elevator high-speed cruising under dangerous situation, become the machine of hurting sb.'s feelings.

Summary of the invention

For addressing the above problem, the purpose of this utility model is to provide a kind of anti-door lock short circuit controller, whether can detect door lock of elevator by short circuit, has increased the safety of elevator.

For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:

A kind of anti-door lock short circuit controller, comprises Room door lock signal input port, gate lock signal input port, Logic control module, maintenance relay output module, door lock relay output module, maintenance signal output port, door lock signal output port;

Described Logic control module one end arranges described Room door lock signal input port and described gate lock signal input port, the other end arranges described maintenance relay output module and described door lock relay output module, described maintenance relay output module connects described maintenance signal output port, and described door lock relay output module connects described door lock signal output port.

The beneficial effects of the utility model are:

Whether the utility model can detect door lock of elevator by short circuit, short circuit elevator can not move normally, once detect that door lock is by short circuit, disconnect immediately maintenance loop, automatically enter service mode to elevator, remind maintainer or passenger can not normally use this elevator, increased the safety of elevator.

Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of specification sheets, below with preferred embodiment of the present utility model and coordinate accompanying drawing to be described in detail as follows.Detailed description of the invention of the present utility model is provided in detail by following examples and accompanying drawing thereof.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Number in the figure explanation:

1, Room door lock signal input port, 2, gate lock signal input port, 3, Logic control module, 4, maintenance relay output module, 5, door lock relay output module, 6, maintenance signal output port, 7, door lock signal output port.

Detailed description of the invention

Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.

Shown in Figure 1, a kind of anti-door lock short circuit controller, comprises Room door lock signal input port 1, gate lock signal input port 2, Logic control module 3, maintenance relay output module 4, door lock relay output module 5, maintenance signal output port 6, door lock signal output port 7;

Described Logic control module 3 one end arrange described Room door lock signal input port 1 and described gate lock signal input port 2, the other end arranges described maintenance relay output module 4 and described door lock relay output module 5, described maintenance relay output module 4 connects described maintenance signal output port 6, and described door lock relay output module 5 connects described door lock signal output port 7.

Door lock of elevator signal is by gate lock and rear door lock safety relay or the contactless switch controlled of Room door lock signal series connection, and gate lock signal is to be in series by all gate lock signals of elevator, and Room door lock signal is to be in series by all Room door lock signal.Normal elevator operation, gate lock signal and Room door lock signal are to disconnect or closed simultaneously.If simple series connection control, be to detect that Room door lock or gate lock by short circuit or damage.In the utility model, Room door lock signal and gate lock signal are input on anti-door lock short circuit controller by described Room door lock signal input port 1 and described gate lock signal input port 2 respectively, by the described Logic control module 3 on described anti-door lock short circuit controller, the signal of input is processed, if action simultaneously, judge that signal is normal, described door lock relay output module 5 is by described door lock signal output port 7 normal output signals, and described maintenance relay output module 4 is not worked; If not action simultaneously, judge signal mal, described door lock relay output module 5 can not output signal, and described maintenance relay output module 4, by described maintenance signal output port 6 output signals, makes elevator enter inspecting state.

The preferred embodiment that the foregoing is only utility model, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
