Description
Technical field
The utility model designs door lock of elevator short circuit detection field, specifically a kind of to detect door lock of elevator with security module
The device of short circuit.
Background technology
Traditional hoistway door, car door lock detection are that landing interlock switch and car door interlock switch are cascaded,
Controller input point is coupled with again, and controller is to detect landing interlock and car door interlock switch by the presence or absence of input signal
It is no normal.But which has the following disadvantages：
（1）Since landing interlock switch and car door interlock switch are cascaded, then it is coupled with controller input point.Such as
Door interlock switch short circuit below, controller can not just be detected corresponding signal by fruit.Such as：When elevator is run, landing interlock
Switch and car door interlock switch are all to be closed, and controller input terminal has signal.Elevator is in stop door opening state, landing interlock
Switch and car door interlock switch are all to disconnect, and controller input terminal does not have signal.If elevator is in stop door opening state, short
Landing interlock switch is connect, even if car door interlock switch disconnects, controller input terminal also no signal can not detect landing interlock and open
The situation of pass, when operation, there is security risk, such as shearing, enabling mule carriage.
（2）For elevator as vertical transport instrument important in building, the work and life with people are closely bound up, and electric
Terraced door contacts the closest with passenger, and the failure overwhelming majority of elevator is all related with elevator door, if door lock of elevator short circuit, especially
It is landing interlock short circuit, controller band hidden danger in the state of it can't detect is run, even if maintenance personal can not obtain feedback
Fault message easily triggers security incident.
Utility model content
The purpose of this utility model is to provide a kind of device with security module detection door lock of elevator short circuit, it can be achieved that detection
State of the elevator in door lock short circuit under stop opens the door state in place,
It is able to detect that fault message of the door lock of elevator in improper short circuit, and can detect the short of each layer hall door
State is connect, is efficiently run so as to which elevator safety be effectively ensured.
To achieve the above object, the utility model provides following technical solution：This detects door lock of elevator with security module
The device of short circuit includes the controller being arranged in computer room and security module, the Room being sequentially connected in series for controlling each stop hall door
Door interlock switch, be arranged on car for the car door interlock of gate to be controlled to switch, be characterized in that：The security module
A pair of of flat bed signal input point, open the door signal input point, an a pair of normally opened signal output point in place are equipped with, when a pair of of flat bed
When signal input point and one open the door that signal input point has signal input simultaneously in place, a pair of normally opened signal output point is closed；Control
Output common point, open the door signal output point, landing interlock switch input point, a peace in place there are one being set on device processed
Full loop input point and a car door interlock signal input point；The enabling of controller signal output point and security module in place
Signal input point in place of opening the door is electrically connected；The safety return circuit input point of controller, landing interlock switch input point respectively with peace
The normally opened signal output point of a pair of full module is electrically connected；Car door interlock switch input point and the safety return circuit input point of controller
Between switched and be electrically connected by car door interlock, the car door interlock of controller switch input point and landing interlock switch input point it
Between switched and be electrically connected by the landing interlock that is sequentially connected in series.
The advantages of the utility model and the positive technique effect generated：The utility model passes through in security module and control
Setting signal test point between device, efficiently solves landing interlock switch or car door interlock is switched when being shorted, and can not send out in time
The problem of now and detecting.It has many advantages, such as testing result accurately and reliably, and detection efficiency is high.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the electric control theory figure of the utility model.
Reference sign：1 computer room, 2 switch boards, 3 security modules, 4 controllers, 5 landing interlocks switch, 6 cars, 7 layers
It stands, 8 hall doors, 9 gates, 10 car door interlocks switch.
Specific embodiment
Below in conjunction with Fig. 1 ~ 2, the content of the utility model is described in detail by specific embodiment.This is detected with security module
The device of door lock of elevator short circuit includes the controller 4 that is arranged in the switch board 2 of computer room 1 and security module 3, for controlling each layer
The landing interlock the being sequentially connected in series switch 5 for 7 hall doors 8 of standing, be arranged on car 6 for the car door interlock of gate 9 to be controlled to switch
10.Wherein, security module is equipped with a pair of of flat bed signal input point C1, C2, signal input point S1, Yi Duichang in place of opening the door
ON signal output point 01,02, for receiving DC24V input signals.When flat bed signal input point C1, C2 and an enabling believe in place
When number input point S1 has signal input simultaneously, normally opened signal output point 01,02 is closed.Output common point there are one being set on controller
COM, 0.1, landing interlock switch 3.1, safety return circuit input point 3.3 of input point of signal output point in place of opening the door
And a car door interlock signal input point 3.2, for exporting or receiving DC24V signals.
Signal input point S1 electrically connects in place for the enabling of the enabling of controller signal output point 0.1 and security module in place
It connects.Safety return circuit input point 3.3, the landing interlock switch input point 3.1 of controller are defeated with the normally opened signal of security module respectively
Go out and a little 01,02 be electrically connected.Pass through sedan-chair between the car door interlock switch input point 3.2 and safety return circuit input point 3.3 of controller
Door interlock switch 10 is electrically connected, between the car door interlock switch input point 3.2 of controller and landing interlock switch input point 3.1
Pass through several landing interlock switches 5 being sequentially connected in series（Number of switches is identical with number of floor levels）It is electrically connected.
Specific work process is as follows：
1）Under normal operating condition, when lift car is parked in corresponding stop level position, security module input point C1 and
C2 persistently inputs DC24V flat bed signals；Hall door and gate are opened, the landing interlock switch 5 of corresponding stop and car door interlock switch
10 disconnect；
2）When gate opens the door in place, the normally opened input point 01 and 02 of security module is closed, only controller input point 3.3
There is the input of AC110V signals；（When elevator normal operation or door-closing in-place state, controller input point 3.1,3.2,3.3 inputs
Point have AC110V signals input, security module 3 only Elevator landing and open the door in place when be detected, if flat bed signal
Or the signal in place that opens the door cancels, then security module is in and does not detect state）
3）Under failure operation state, if controller input point 3.2 detects AC110V signals（Under normal circumstances without letter
Number）, then illustrate that landing interlock switch 5 or car door interlock switch 10 are shorted, elevator report failure；
4）If testing result is normal, controller output end 0.1 stops output DC24V enablings signal in place, safe mould
Block input point 01 and 02 disconnects, and system enters holding state, waits detection of opening the door next time.
