An embodiment of the present invention will be described below with reference to FIGS. 1 to 3 .

Fig. 1 is a schematic structural view of an elevator according to the present embodiment.

Elevator car 1 is arranged in the hoistway that is not shown in the figure, and this elevator car 1 is provided with the elevator door 2 that can be opened and closed for allowing passengers to get on and off the elevator and an operating panel 3, and the operating panel 3 is provided with a The floor button 4 indicating the destination, the elevator door opening button 5 and the elevator door closing button 6 instructing the elevator door 2 to open and close the door, and the intercom for communication between the outside and the inside of the elevator car, etc. Contact device 7.

In addition, an elevator car position detection device 8 and an elevator car control device 9 for detecting the position of the elevator car 1 are arranged outside the elevator car 1, and the elevator car control device 9 performs opening and closing control of the elevator door 2 and Various controls related to the elevator car, such as display control based on the detection signal of the elevator car position detection device 8 , are provided with an input/output device connected to the external detection and control device 10 .

In addition, the elevator car position detection device 8 is connected to an external detection and control device 10 that performs elevator speed control, abnormality and failure detection, and the like.

In the above-mentioned elevator, when an abnormality or failure occurs, the elevator car stops urgently. At this time, the abnormality or failure detection device not shown in the figure detects the abnormality or failure, and an abnormality indicating that the abnormality or failure has occurred will be displayed. The detection signal is output to the elevator car control device 9 and an elevator control center (not shown).

The elevator car control device 9 that has received the abnormality detection signal judges whether the emergency stop position of the elevator car is located in the elevator door opening and closing area according to the position signal received from the elevator car position detection device 8 through its input and output device. If the judgment result is that the elevator door is in the openable and closable area, a judgment signal indicating that the elevator is located in the elevator door openable and closable area is output to the external detection and control device 10 .

Received the external detection and control device 10 of this judging signal to judge whether this elevator can eliminate abnormality or failure by starting confirming device, get back to normal state and start, when the judging result is that the elevator can't start, it will report to the elevator car control device 9. Outputting an elevator door lock release instruction signal, and simultaneously output an elevator door opening and escape instruction signal for instructing passengers to open the elevator door and to escape from the elevator.

The elevator car control device 9 that receives the instruction signal releases the elevator door lock according to the elevator door lock release instruction signal, and at the same time according to the elevator door opening and escape instruction signal, by making the elevator door open button 5 light up or flash, etc. Inform the passenger to open the elevator door and escape from the elevator, or inform the passenger to open the elevator door and escape from the elevator through a communication device 7 such as an intercom phone in the form of a voice prompt.

On the other hand, when the emergency stop position of the elevator car is not located in the area where the elevator door can be opened and closed, it will be processed after the technical maintenance personnel arrive.

The operation of the present invention will be described below with reference to the flowchart of FIG. 3 .

In step S1, when elevator carries out normal operation, enters step S2, judges whether there is abnormality or failure occurs, when the judged result is that abnormality or failure do not occur, returns to step S1 and continues normal operation.

In the judgment of step S2, when the emergency stop of the elevator car 1 etc. is detected, it progresses to step S3.

In step S3, the process proceeds to steps S4 and S9 after outputting an abnormality detection signal to the elevator car control device 9 and the elevator control center.

In step S4, the elevator car control device 9 having received the abnormality detection signal detects the emergency stop position of the elevator car according to the signal of the elevator car position detection device 8, and then proceeds to step S5.

In step S5, it is judged whether the emergency stop position of the elevator car is in the openable and closable area of the elevator door, if not in the openable and closable area of the elevator door, enter step S10, and wait for the technical maintenance personnel to arrive.

In step S5, when it is judged that the emergency stop position is within the openable and closable area of the elevator door, the process proceeds to step S6, where it is judged whether the elevator can be started by a not-shown start confirmation device.

When the judging result is that the elevator can be started, it proceeds to step S10 and waits for the arrival of technical maintenance personnel.

On the other hand, when it is judged that the elevator cannot be started in step S6, it progresses to step S7.

In step S7, the elevator car control device 9 releases the lock of the elevator door, and simultaneously controls the elevator door opening button 5 to light or flash to notify passengers to open the elevator door of the elevator car and escape from the elevator in the form of light. The internal intercom informs the passenger to open the elevator door of the elevator car and escape from the elevator in the form of a voice prompt, and then enters step S8.

In step S8, the passenger opens the elevator door 2 and escapes from the elevator according to the notification of opening the elevator door and fleeing from the elevator.

In addition, in order to further improve the safety of the passengers who are locked in the elevator car when they escape, in addition to notifying the passengers to open the elevator door and escape from the elevator, the light and flashing of the elevator door open button 5 can also be carried out. Periodically, it is also possible to notify that there is a height difference between the floor surface of the elevator car that has stopped in an emergency and the floor surface of the elevator lobby on the nearest floor as described below.

For example, as shown in Figure 2, when the height difference h between the elevator car 1 and the elevator hall 11 on the nearest floor is more than ±75mm, the light is turned off, and it flashes slowly when it is between ±75mm and ±15mm. It flashes at a fast speed when it reaches ±5mm, and turns on when it is within ±5mm, so that you can grasp the approximate stop position.

In addition, generally speaking, flickering at a frequency of 6 to 12 Hz causes unpleasant feeling, so the frequency is set to a frequency band below 6 to 12 Hz. In the example of FIG. 2 , the frequency of the slower blinking is set to 1 Hz, and the frequency of the faster blinking is set to 2 Hz.

As a display pattern of lighting or blinking at this time, the order of blinking→blinking→lighting may be set like a Morse signal.

In addition, the height difference information can be expressed in more detail by subdividing the representation form into four more representation forms than lighting, fast blinking, slow blinking, and turning off the light. In addition, the lighting Perhaps flashing is not limited to be carried out by elevator door open button 5, also can be carried out by elevator door close button 6 or floor button 4, and special-purpose indicating device can also be provided with. In addition, the combination of lighting and blinking is not limited to the above combinations.

According to the above embodiments, the following effects can be achieved.

In the prior art, technical maintenance personnel rush to the scene to rescue passengers after abnormal detections such as emergency stop, but the present invention only locates the emergency stop position of the elevator car 1 within the openable and closed area of the elevator door and the elevator cannot start. In this state, passengers can be quickly rescued before maintenance personnel arrive.

And, after confirming that the elevator will not move suddenly, the lock of the elevator is released, so that the elevator door can be opened, so when the passenger who is closed in the elevator car escapes from the elevator door, the elevator will not move, thereby making it possible for passengers to be safe. And literally escape the elevator.

In addition, since the height difference h between the floor surface of the elevator car 1 and the floor surface of the elevator hall 11 can be predicted by lighting or flashing, when the height difference h is large, passengers can be reminded in advance Pay attention when escaping, so the safety when escaping can be improved.

As a modified example, in order to ensure safety when the abnormality or fault detection device malfunctions, it is confirmed whether there are passengers locked in the elevator car through the intercom through the voice mode, and the voice confirmation is received from the passenger. The confirmation signal of the elevator car and the condition that the elevator cannot be started are used to unlock the elevator door of the elevator car, so that the safety can be further improved.

And, when carrying out the notification of voice form, besides the notification of opening the elevator door and escaping from the elevator, for example, the notification of how to perform the elevator door opening operation and the degree of the height difference h can also be added.

The announcement of opening the elevator door and escaping from the elevator can be done by a floor button, a dedicated button can also be set, it can also be done by a visual and voice device, and it can also be done by a combination of lighting and flashing.
