Fig. 2 is the work flow diagram of the layer door detector of embodiment one.
Fig. 3 is the work flow diagram of the master board of embodiment one.
Specific embodiment
Embodiments of the present invention are described in detail below in conjunction with attached drawing.
Embodiment one
Such as Fig. 1, a kind of elevator door detection device, including be set to the floor door of each floor, be set to each floor respectively with the building
Layer the corresponding layer door detector of layer door, set on each floor floor control panel, elevator master board.The door lock of elevator door
It is provided only with a single test point, the door lock one-to-one correspondence of layer door detector and elevator door is connected to single inspection of the floor door lock
Whether measuring point is opened or failure for detecting door lock.Layer door detector can be passive mechanical contact, optoelectronic switch, fine motion
Switch, magnetic switch, safety switch or sensor.The door lock of the layer door of each floor is parallel with one another, and is formed into a loop with power supply.
Floor control panel includes detection port and PORT COM, detection output and the floor control panel of layer door detector
Port electrical connection is detected, door lock abnormal signal is sent when detecting door lock unlatching or failure to floor control panel.Floor control
Making sheet is additionally provided with PORT COM, is electrically connected realization communication by communication cable between master board and floor control panel.Communication side
Formula can be RS-232, RS-485, CAN, LONworks, profibus, LINbus etc..Master board, floor control panel composition
Communication network, the floor control panel of each floor are exactly that a network node in entire communication system is led to master board
News.In order to avoid Communications failure or communication interference, network node（Floor control panel）With main PORT COM（Master board）Between
Using twin-channel communication link.Meanwhile will test the top that port is set to floor control panel, PORT COM is set to floor control panel
Lower part so that detection port is separated from each other with PORT COM, and as far as possible every far mutual interference must be avoided.
Display unit is equipped between detection port and the PORT COM of lower part on floor control panel top, display unit can
Think liquid crystal display, segment display or matrix display.Alternatively, floor control panel can be divided into two independent communications
Plate and display board.PORT COM and detection port are set on the communication board, and are located at the lower part and top of communication board,
Display unit is separately provided on the display panel；Display port is arranged in the side of communication board, for being electrically connected with display board.Layer door inspection
It surveys device and sends door lock opening imformation when detecting door-lock opening to floor control panel, on the one hand floor control panel is opened in door lock believes
Affix floor information is sent to master board in breath；On the one hand judge that whether abnormal door lock is opened, and is judging that door lock opens simultaneously
Opening abnormal is to show that door lock opens exception information by display unit, and maintenance personal is facilitated to check.
When master board receives the door lock opening imformation from floor control panel, sentence in conjunction with the operating status of elevator at that time
Whether disconnected door lock is opened abnormal.If elevator is in operating 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 and be equal to the floor that door lock is opened, then door lock open it is normal；Otherwise,
Door lock is opened abnormal.
If master board judges that door lock opens the lower section abnormal, optionally operation lift car is opened to door lock.It is main
Control panel can formulate operation reserve according to the current location of elevator：If floor where elevator is located at the building of door lock unlatching at this time
Under layer, master board control elevator runs next layer or the master board control elevator operation for the floor opened to door lock
Between the floor that the next layer and door lock for the floor opened to door lock are opened；If floor where elevator is located at door lock unlatching at this time
Floor on, master board control elevator it is out of service.During running elevator, master board can control elevator with
Slow speed operation（The speed operated normally less than elevator）, to reduce the risk that accident occurs.
If there is the door lock abnormal start-up of multiple floors in the same time, 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 floor where elevator is located under the floor of door lock unlatching at this time, master board control elevator, which is run to door lock, to be opened
Floor next floor or master board control elevator run to door lock open floor next floor and door lock open building
Between layer（On condition that the operating path opens abnormal floor without going past other door locks）；If floor position where elevator at this time
On the floor that door lock is opened, it is out of service that master board controls elevator.During running elevator, master board can be with
Control elevator is run with slow speed（The speed operated normally less than elevator）, to reduce the risk that accident occurs.
Although the embodiments of the invention are described in conjunction with the attached drawings, but those of ordinary skill in the art can be in appended power
Benefit makes various deformations or amendments in the range of requiring.
