Connect；, on the communication board, the display panel is provided with display unit for the PORT COM and the detection port.So that being located at
The floor panel of each floor can show the fault message of door lock, convenient maintenance.
Preferably, the layer door detector sends door lock opening imformation to the main control when door-lock opening is detected
Plate, the door lock opening imformation is including at least the floor information for representing layer door detector place floor.
If preferably, elevator is in running status, institute when the master board receives the door lock opening imformation
State master board and judge that exception opened by door lock.
If preferably, the master board receive the door lock opening imformation when elevator be in halted state, and
The stopping floor of elevator is different from the floor that door lock is opened, then the master board judges that exception opened by door lock.
If preferably, master board judges that exception opened by door lock, and now elevator place floor is opened positioned at door lock
Under the floor for opening, the master board control elevator runs next layer of the floor that opens to door lock.
If preferably, master board judges that exception opened by door lock, and now elevator place floor is opened positioned at door lock
Under the floor for opening, the master board control elevator runs the floor that opens to door lock so that elevator runs to door lock and opens
Floor next layer and door lock open floor between.
If preferably, master board judges that exception opened by door lock, and now elevator place floor is opened positioned at door lock
On the floor for opening, the master board control elevator is out of service.
Due to parallel with one another between door lock, the layer door lock of at least one floor is just for the elevator door detection means of the present invention
Often elevator can just run；Layer door detector is electrically connected with floor panel, and the master board when layer door lock is abnormal can be obtained
Know abnormal door lock place floor；Master board is leaned in the case where meeting some requirements according to current floor and elevator operation
The lower section of the abnormal floor of nearly door lock, when there is layer door of the passenger through abnormal door lock to be strayed into hoistway, rests in the sedan-chair below floor
During railway carriage or compartment can avoid falling to hoistway or reduce the height that falls of passenger.

Specific embodiment
Embodiments of the present invention are described in detail below in conjunction with accompanying drawing.
Embodiment one
Such as Fig. 1, a kind of elevator door detection means, including the layer door located at each floor, located at each floor respectively with the floor
The corresponding layer door detector of layer door, the floor panel located at each floor, the master board of elevator.The door lock of elevator door only sets
There are a single test point, layer door detector to correspond with the door lock of elevator door, be connected to single test point of the floor door lock,
For detecting whether door lock is opened or failure.Layer door detector can be passive mechanical contact, photoswitch, microswitch,
Magnetic switch, safety switch or sensor.The door lock of the layer door of each floor is parallel with one another, and forms loop with power supply.
Floor panel includes detecting port and PORT COM, the detection output of layer door detector and floor panel
The electrical connection of detection port, sends door lock abnormal signal to floor panel when door lock unlatching or failure is detected.Floor control
Making sheet is additionally provided with PORT COM, electrically connects realization communication by communication cable between master board and floor panel.Communication side
Formula can be RS-232, RS-485, CAN, LONworks, profibus, LINbus etc..Master board, floor panel composition
Communication network, the floor panel of each floor are exactly that a network node in whole communication system is led to master board
News.In order to avoid Communications failure or communication interference, network node（Floor panel）With main PORT COM（Master board）Between
Using twin-channel communication link.Meanwhile, by detection port located at the top of floor panel, PORT COM is located at floor panel
Bottom so that detection port is separated from each other with PORT COM, and as far as possible every must far, it is to avoid interference each other.
Display unit is provided between the detection port on floor panel top and the PORT COM of bottom, display unit can
Think liquid crystal display, segment display or matrix display.Or, floor panel can be divided into two independent communications
Plate and display panel.PORT COM and detection port are located on the communication board, and are located at the bottom and top of communication board respectively,
Display unit is separately provided on the display panel；The side of communication board arranges display port, for electrically connecting with display panel.Layer door inspection
Surveying device and door lock opening imformation being sent when door-lock opening is detected to floor panel, on the one hand floor panel opens letter in door lock
In breath, affix floor information is sent to master board；On the one hand simultaneously judge that whether extremely door lock is opened, judging that door lock opens
It is to show that abnormal information opened by door lock by display unit to open abnormal, facilitates maintainer to investigate.
Master board receive from the door lock opening imformation of floor panel when, the running status in conjunction with elevator at that time is sentenced
Whether disconnected door lock is opened abnormal.If elevator is in running status at that time, it is abnormal that master board judges that door lock is opened.If worked as
When elevator be in run-stopping status, and stop floor equal to the floor that door lock is opened, then door lock is opened normal；Otherwise,
Door lock is opened abnormal.
If master board judges that abnormal, the lower section that optionally operation lift car is opened opened to door lock by door lock.Main
Panel can formulate operation reserve according to the current location of elevator：If now elevator place floor is located at the building that door lock is opened
Under layer, master board control elevator runs next layer of the floor that opens to door lock, or master board control elevator operation
Between the floor that next layer and door lock of the floor that opens to door lock is opened；If now elevator place floor is opened positioned at door lock
Floor on, master board control elevator out of service.Operation elevator during, master board can control elevator with
Slow speed operation（Less than the speed that elevator normally runs）, to reduce the risk that accident occurs.
If there is the door lock abnormal start-up of multiple floors the same time, then master board optionally runs lift car extremely
The higher door lock of floor position is opened below abnormal floor.Master board can formulate operation plan according to the current location of elevator
Slightly：If now elevator place floor is located under the floor that door lock is opened, master board control elevator is run to door lock to be opened
Floor next floor or master board control elevator run the building that next floor and the door lock of the floor that opens to door lock are opened
Between layer（On condition that the operating path opens abnormal floor without going past other door locks）；If now elevator place floor position
On the floor that door lock is opened, master board control elevator is out of service.During operation elevator, master board can be with
Control elevator is run with slow speed（Less than the speed that elevator normally runs）, to reduce the risk that accident occurs.
Although being described in conjunction with the accompanying embodiments of the present invention, those of ordinary skill in the art can be in appended power
Profit makes various modifications or modification in the range of requiring.
