Fig. 8 is a flowchart of a working method of the intelligent escaping elevator provided by the embodiment of the present invention. The working method of the intelligent escaping elevator comprises the following steps:
s81, the controller detects that the safety loop has a fault;
when the elevator normally operates, the intelligent escaping mode cannot be started. The controller determines whether the safety loop is failed by detecting the voltage at point a in fig. 7.
S82, the controller starts an intelligent escaping mode when detecting that a person is in the car through the human body induction module;
human response module can be infrared camera, and when the elevator broke down, the controller acquireed the interior image of car that infrared camera was shot, judges whether someone, and when someone, automatic start intelligence mode of getting rid of poverty.
S83, when the human body induction module is in failure or the controller detects that no person exists in the car through the human body induction module, and the duration time for simultaneously pressing the door closing button and the door opening button is longer than the preset time, starting an intelligent escaping mode;
when the human body induction module fails or trapped people are in dead corners of the infrared camera, the trapped people can not be shot. At the moment, when the duration of pressing down the door closing button and the door opening button simultaneously is longer than the preset time, the intelligent escaping mode is determined to be started manually. The preset time can be set according to actual conditions and can be 2 s.
S84, after the intelligent escaping mode is started, the controller judges whether the elevator car is in a flat zone or not, and the controller determines that the elevator car is in a non-flat zone;
after the intelligent escaping mode is started, whether the elevator car is in a flat zone or not is judged, namely whether the car door faces to a hall door or not, if the elevator car is in the flat zone, the elevator does not need to be operated, namely, when the elevator car is determined to be in the flat zone, the controller outputs a door opening instruction to open the hall door and the car door. When in a non-leveling zone, the elevator needs to be run to the leveling zone.
S85, the controller determines that the car door and the hall door at each floor are closed and determines that the door lock detection circuit is normally conducted;
the controller determines that the car door and the hall door are closed, and the door lock detection circuit is normally conducted, namely the car door lock and each hall door lock are in a locking state, so that the situation that the car door and the hall door are not closed or the elevator is operated under the situation that the car door lock and the hall door lock are not locked is avoided, and accidents are easy to occur when the elevator is operated under the situation. To ensure safety, it is necessary to determine the closing condition of the car door, the hall door, and the locking condition of the door lock.
S86, the controller outputs an automatic rescue operation instruction to the lifting device, so that the lift car can move to the nearest landing door at a preset speed;
the preset speed is 0.1-0.2 m/s low speed.
And S87, the controller outputs a door opening command to open the car door and the hall door opposite to the car door.
In one embodiment, when the controller detects that the safety loop is failed, the controller controls the voice playing device to play a pre-stored audio file. The preset audio file stores preset audio. When the intelligent escaping mode is not started, the playing audio is used for prompting the user to simultaneously press the door opening button and the door closing button to start the intelligent escaping mode, and when the intelligent escaping mode is started, the playing audio prompts the user to execute the intelligent escaping mode.
In one embodiment, after the intelligent escaping mode is started, the controller stops the intelligent escaping mode when detecting that any hall door is opened, the elevator stops running, and when the hall door is detected to be closed again, the intelligent escaping mode is restarted.
In an embodiment, after the intelligent escaping mode is started, when the door closing button and the door opening button are not simultaneously pressed, the intelligent escaping mode is stopped, the elevator stops running, and when the situation that the door closing button and the door opening button are simultaneously pressed for more than the preset time is detected again, the intelligent escaping mode is restarted. When the intelligent escaping mode is started manually, when the elevator runs in the leveling zone, the door closing button and the door opening button are pressed manually all the time to keep the elevator running. Therefore, when the trapped person needs to temporarily operate the elevator, the operation can be stopped at any time.
In one embodiment, after the intelligent escaping mode is started, the controller outputs a door opening command to open the hoistway door and the car door when the controller determines that the car is in the landing zone.
While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the foregoing and various other changes, omissions and deviations in the form and detail thereof may be made without departing from the scope of this invention.
