Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
Example 1
Fig. 1A is a flowchart of an elevator maintenance door opening method provided in an embodiment of the present invention, where the embodiment is applicable to determining a hall door that can be safely opened during elevator maintenance, and the method may be performed by an elevator maintenance door opening device provided in an embodiment of the present invention, where the device may be implemented by software and/or hardware, and configured in a computer device provided in an embodiment of the present invention, as shown in fig. 1A, and the method specifically includes the following steps:
s101, when the elevator stops accidentally, controlling a light source on the car to be started.
In the embodiment of the invention, the unexpected elevator stopping can be caused by unexpected power failure, elevator fault and the like, and the embodiment of the invention is not limited herein. When the elevator stops accidentally, a maintenance person is required to forcibly open a hall door of a certain floor to enter the elevator car or enter the elevator car. Because the car accidentally stops the elevator, the maintenance personnel cannot accurately know the current stop position of the car. If a landing door on a floor is opened, a fall event may occur.
In the embodiment of the invention, the light source can be arranged at the top of the car, and the light source is a light source with a fixed light emitting angle and a certain radiation range, such as a spotlight. When the elevator stops accidentally, the light source on the elevator car is controlled to be started, and the light source emits light in a specified direction.
S102, determining a target hall door which can be safely opened based on light emitted by a light source received by a light receiving structure in an elevator shaft of each floor, wherein when a car is at a flat floor position, the light emitted by the light source covers the light receiving structure of the floor and the light receiving structure of the previous floor, and when the car is between two floors, the light emitted by the light source covers the light receiving structure of the higher floor of the two floors.
Fig. 1B is a schematic view of a car in a flat floor position, fig. 1C is a schematic view of a car between two floors, and as shown in fig. 1B and 1C, in an embodiment of the present invention, a light receiving structure is disposed in an elevator hoistway of each floor, and the light receiving structures are disposed equidistantly. The light emitted by the light source can only cover two light receiving structures at most, and only when the car is in a flat layer position (namely the car accurately stops at a certain floor), the light emitted by the light source covers the light receiving structure of the floor and the light receiving structure of the previous floor. For example, if the car is parked at the level 5 floor position, the light from the light source covers the light receiving structure of level 5 and the light receiving structure of level 6. When the car is between two floors, the light emitted by the light source covers the light receiving structure of the higher floor of the two floors. For example, if the car is parked between floors 5 and 6, the light source emits light that only covers the light receiving structure of floor 6.
In the embodiment of the invention, the target hall door capable of being safely opened refers to a hall door which can be safely opened by maintenance personnel and safely enters a car or the top of the car from the hall door without falling accidents.
Since the light emitted from the light source covers the light receiving structure of the floor and the light receiving structure of the previous floor when the car is in the flat position, the light emitted from the light source covers the light receiving structure of the higher floor of the two floors when the car is between the two floors. Thus, the target hall door that can be safely opened can be determined from the light emitted from the light source received by the light receiving structure in the elevator hoistway of each floor. When the two light receiving structures receive the light emitted by the light source, the elevator car is at the flat layer position of the floor corresponding to the lower one of the two light receiving structures, and the hall door of the floor where the two light receiving structures are located is a target hall door which can be safely opened. When one light receiving structure receives the light emitted by the light source, the elevator car is positioned between the floor where the light receiving structure is positioned and the next floor, and the hall door of the floor where the light receiving structure is positioned is a target hall door which can be safely opened. For example, if the car is parked at the level floor position of the 5 th floor, the light emitted from the light source covers the light receiving structure of the 5 th floor and the light receiving structure of the 6 th floor, and the hall doors of the 5 th floor and the 6 th floor are target hall doors that can be safely opened. If the car stops between the 5 th floor and the 6 th floor, the light emitted by the light source can only cover the light receiving structure of the 6 th floor, and the hall door of the 6 th floor is a target hall door which can be safely opened.
According to the elevator maintenance door opening method provided by the embodiment of the invention, when an elevator stops accidentally, a light source on a car is controlled to be started, a target hall door which can be safely started is determined based on light emitted by a light source received by a light receiving structure in an elevator shaft of each floor, when the car is in a flat-layer position, the light emitted by the light source covers the light receiving structure of the floor and the light receiving structure of the upper floor, and when the car is between two floors, the light emitted by the light source covers the light receiving structure of the higher floor in the two floors. The problem that the hall door is opened and the falling accident occurs under the condition that the position of the car is not clear by maintenance personnel is avoided, and the safety is improved.
In some embodiments of the present invention, as shown in fig. 1B and 1C, the light receiving structure is a light sensing switch, and determining a target hall door that can be safely opened based on light emitted from a light source received by the light receiving structure disposed in an elevator hoistway of each floor includes:
when the light sensing switch senses light, the hall door of the floor where the light sensing switch is located is determined to be a target hall door which can be safely opened.
The light sensing switch senses light, and the light sensing switch receives the light emitted by the light source, so that the hall door of the floor where the light sensing switch is positioned is a target hall door which can be safely opened. In some embodiments of the present invention, when the light-sensitive switch senses light, a switch signal is generated, and it may be determined that a hall door of a floor where the light-sensitive switch is located is a target hall door that can be safely opened based on the received switch signal.
In some embodiments of the present invention, the hall doors of each floor are provided with an indicator light, and the indicator light of each floor is connected to the light-sensitive switch of that floor. When the light sensing switch senses light, the light sensing switch is turned off to enable the indicator lamp to send out a first indicator signal so as to remind maintenance personnel of the fact that the hall door of the floor is a target hall door capable of being safely opened. When the light sensing switch does not sense light, the light sensing switch is started to enable the indicator lamp to send out a second indicator signal so as to remind the maintenance personnel that the hall door of the floor is a hall door which is forbidden to be started. For example, if the car stops at the level position of the 5 th floor, the light-sensitive switches of the 5 th floor and the light-sensitive switches of the 6 th floor are sensitive, and then the indicator lights on the hall doors of the 5 th floor and the 6 th floor emit a first indicator signal (for example, emit green light) to remind the maintenance personnel that the hall doors of the 5 th floor and the 6 th floor are target hall doors which can be safely opened, the light-sensitive switches of the rest floors are not sensitive, and the indicator lights of the rest floors emit a second indicator signal (for example, emit red light) to remind the maintenance personnel that the hall doors of the rest floors are hall doors which are forbidden to be opened. If the car stops between the 5 th floor and the 6 th floor, the light-sensitive switch of the 6 th floor senses light, and the indicator light on the hall door of the 6 th floor sends out a first indicator signal (for example, sends out green light) to remind the maintenance personnel that the hall door of the 6 th floor is a target hall door which can be safely opened, the light-sensitive switches of the rest floors do not sense light, and the indicator lights of the rest floors send out a second indicator signal (for example, send out red light) to remind the maintenance personnel that the hall door of the rest floors is a hall door which is forbidden to be opened.
In some embodiments of the invention, each floor is provided with a voice alarm, and the elevator maintenance door opening method further comprises:
and the door lock key detection module is used for detecting whether a door lock key hole of the hall door is inserted with a key or detecting whether the key is rotated or not.
When the detection signal indicates that the key hole of the door lock is inserted into the key or the key is turned, and the hall door is a non-target hall door, the voice alarm is controlled to send an alarm signal for prohibiting door opening.
The door lock of the hall door can be provided with a door lock key detection module, and the door lock key detection module is used for detecting whether a door lock keyhole of the hall door is inserted with a key or detecting whether the key is rotated. Illustratively, the door lock key detection module may include a metal thimble that maintains a constant potential at ordinary times, and when a maintenance person inserts a key into a door lock key hole of a hall door, the metal thimble contacts with the door lock, resulting in a change in the potential of the metal thimble, thereby detecting the insertion of the key. It should be noted that the above-mentioned metal thimble is an exemplary illustration of the door lock key detection module, and not limited thereto, and in other embodiments of the present invention, other structures may be replaced, for example, an infrared distance detection module, etc., where when a maintenance person inserts a key into a door lock keyhole of a hall door, the infrared distance detection module detects that the key is close to the key, so that the insertion of the key is detected. When a key is inserted into a door lock keyhole of a certain hall door, and the hall door is a non-target hall door, the voice alarm is controlled to send an alarm signal for prohibiting door opening, and an alarm prompt is sent when a maintenance person inserts the key, so that the safety is further improved.
Fig. 1D is a schematic structural view of a door lock key detection module according to an embodiment of the present invention, fig. 1E is a schematic structural view of another door lock key detection module according to an embodiment of the present invention, and fig. 1F is a schematic structural view of another door lock key detection module according to an embodiment of the present invention, and exemplary, as shown in fig. 1D to fig. 1F, in some embodiments of the present invention, a door lock key detection module includes a pulling piece for unlocking and an inductive switch, the pulling piece is connected with a locking rod of a door lock, when the key is turned, the locking rod and the pulling piece are driven to rotate, and the inductive switch is triggered before the pulling piece opens a door lock of a hall door. Wherein, the pulling piece needs to be rotated 180 degrees to unlock the door lock. If the hall door is a non-target hall door, when the inductive switch is triggered, the voice alarm sends out an alarm signal for prohibiting the door from being opened, and sends out an alarm prompt before the maintenance personnel opens the door lock, so that the safety is further improved.
As shown in fig. 1D, the inductive switch may be an infrared pair of tubes (including opposite infrared transmitting tubes and infrared receiving tubes), and before the key is not turned, the pulling piece is located between the infrared pair of tubes, and blocks infrared light of the infrared transmitting tubes, so that the infrared receiving tubes cannot receive infrared light. When the key is turned by an angle (the angle is less than 180 DEG, the door lock is not yet opened), the pulling piece moves away from between the infrared pair of tubes, the infrared receiver receives infrared light, and the inductive switch is triggered.
As shown in fig. 1E, the sensing switch may include a sensing light source and a color sensor, where the color coating is coated on the dial, and before the key is not turned, the dial faces the light source and the color sensor, and light emitted by the sensing light source is reflected by the color coating on the dial to form color light, and is received by the color sensor. When the key is turned by a certain angle (the angle is smaller than 180 degrees, and the door lock is not yet opened), the pulling piece moves away from the sensing switch, the color sensor cannot receive the corresponding color light, and the sensing switch is triggered.
As shown in fig. 1F, the inductive switch may include a magnet and a magneto-resistive element, the magnet being disposed on the paddle, the magnet being proximate to the magneto-resistive element before the key is not turned. When the key is turned by a certain angle (the angle is smaller than 180 DEG, and the door lock is not yet opened), the poking plate drives the magnet to move away from the magnetic resistance element, the magnetic field induced by the magnetic resistance element is weakened, and the induction switch is triggered.
Fig. 1G is a schematic view of a car in a flat-bed position, fig. 1H is a schematic view of a car between two floors, and as shown in fig. 1B and 1C, in an embodiment of the present invention, a light receiving structure includes an observation hole formed on a hoistway door, and a target hoistway door capable of being safely opened is determined based on light emitted from a light source received by the light receiving structure in an elevator hoistway of each floor, including:
when the light emitted by the light source is transmitted through the observation hole, the hall door of the floor where the observation hole is positioned is determined to be a target hall door which can be safely opened.
For example, if the car is parked at the level floor position of the 5 th floor, the light emitted from the light source may pass through the observation hole of the 5 th floor and the observation hole of the 6 th floor, and the hall doors of the 5 th floor and the 6 th floor are target hall doors that can be safely opened. If the car stops between the 5 th floor and the 6 th floor, the light emitted by the light source can only pass through the observation hole of the 6 th floor, and the hall door of the 6 th floor is a target hall door which can be safely opened.
In the embodiment of the present invention, whether the light emitted from the light source passes through the observation hole may be determined by observing the observation hole by human eyes or by a light sensor or the like, and the embodiment of the present invention is not limited herein. The observation hole can be a through hole on the door plate of the hall door, or a piece of glass or other transparent materials can be added after the door plate is perforated, and the surface of the glass is subjected to special treatment (such as slight frosting) so as to avoid dazzling caused by direct observation of the light source by human eyes.
Fig. 1I is a schematic structural view of a light receiving structure provided in an embodiment of the present invention, fig. 1J is a schematic view of a light barrier rotated by a certain angle, and as shown in fig. 1I and fig. 1J, the light receiving structure further includes a pulling plate and a light barrier for unlocking, wherein the pulling plate and the light barrier are both connected with a lock rod of a door lock, and when a key is rotated, the lock rod, the pulling plate and the light barrier are driven to rotate, and the light barrier is triggered to move away from an observation hole before the pulling plate opens the door lock of a hall door. Specifically, before the key is not rotated, the light barrier just shields the observation hole, and the light emitted by the light source cannot penetrate through the observation hole. When the key is turned by an angle (e.g., 60 degrees, which is less than 180 degrees, and the door lock is not yet opened), the light barrier is moved away from the viewing aperture, and the light from the light source can be transmitted through the viewing aperture. In the process of turning the key, the maintenance personnel can check whether the light emitted by the light source can be seen through the observation hole before unlocking the door lock by 180 degrees, so that whether the hall door is a target hall door which can be safely opened or not is determined. If light is visible, the key unlock can continue to be turned and the hoistway door opened. If the light is not visible, turning of the key is stopped.
Fig. 1K is a schematic view of a car in a flat landing position, and fig. 1L is a schematic view of a car between two floors, in which in an embodiment of the present invention, considering the space limitation between the elevator car and the front wall of the hoistway, the distance between the car and the hoistway door is too narrow, and the irradiation range of one light source is limited. Thus, one light source may be added. The light emitted by the two light sources can only cover the two light receiving structures at most, and only when the car is in the flat-layer position (namely, the car accurately stops at a certain floor), the light emitted by the two light sources covers the light receiving structure of the floor and the light receiving structure of the previous floor. When the car is between two floors, the light emitted by the two light sources covers the light receiving structure of the higher floor of the two floors.
Further, the two light sources can be set to be different in light-emitting color, for example, the light source at the top of the elevator car emits red light, if the red light is seen from the observation hole, the light source at the front wall of the elevator car emits green light, if the green light is seen from the observation hole, the light source enters from the hall door and goes to the elevator car, and the operator can conveniently judge the relative position relationship between the elevator car and the operator in advance.
