Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1A is a flowchart of an elevator maintenance door opening method according to an embodiment of the present invention, where this embodiment is applicable to determining a hall door that can be safely opened during elevator maintenance, and this method may be implemented by an elevator maintenance door opening apparatus provided in an embodiment of the present invention, where this apparatus may be implemented by software and/or hardware, and is configured in a computer device provided in an embodiment of the present invention, as shown in fig. 1A, where this method specifically includes the following steps:
s101, when the elevator is stopped accidentally, the light source on the elevator car is controlled to be turned on.
In the embodiment of the present invention, the elevator may be stopped due to unexpected power failure, elevator failure, and the like, which is not limited herein in the embodiment of the present invention. When the elevator is stopped accidentally, maintenance personnel are required to forcibly open the landing door of a certain floor to enter the elevator car or the elevator car. Because the lift car stops accidentally, the maintenance personnel cannot accurately know the current stopping position of the lift car. A fall event may occur if a landing door on a floor is opened by trade.
In the embodiment of the invention, the light source can be arranged on 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 spot light. When the elevator stops accidentally, the light source on the elevator car is controlled to be turned on, and the light source emits light in the designated direction.
S102, determining a target hoistway door capable of being opened safely based on light emitted by a light source received by a light receiving structure in an elevator hoistway of each floor, wherein when the elevator car is in a flat position, 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 elevator car is between two floors, 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 the car in a flat position, and fig. 1C is a schematic view of the car between two floors, as shown in fig. 1B and fig. 1C, in the embodiment of the present invention, light receiving structures are provided in the elevator shaft of each floor, and the light receiving structures are arranged at equal distances. The light emitted by the light source can only cover two light receiving structures at most, and only when the elevator car is in a flat floor position (namely the elevator car is accurately stopped 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. Illustratively, if the car is parked at the level position on floor 5, then the light source emits light that covers the light receiving structures on floor 5 and the light receiving structures on floor 6. When the car is between two floors, the light that the light source sent covers the photic structure of the higher floor in two floors. For example, if the car stops between the 5 th floor and the 6 th floor, the light emitted from the light source can only cover the light receiving structure of the 6 th floor.
In the embodiment of the invention, the target hall door capable of being opened safely refers to a hall door which can be opened by maintenance personnel and safely enters the car or the top of the car from the hall door without falling.
Because when the car was in the flat bed position, the light that the light source sent covered the photic structure of this floor and the photic structure of last floor, when the car was in between two floors, the photic structure of the higher floor in two floors was covered to the light that the light source sent. Therefore, the target landing door which can be safely opened can be determined according to the light emitted by the light source received by the light receiving structure in the elevator shaft of each floor. When two light receiving structures receive the light emitted by the light source, the elevator car is positioned at the flat floor position of the floor corresponding to the lower light receiving structure of the two light receiving structures, and the hall door of the floor where the two light receiving structures are positioned is a target hall door capable of being opened safely. When one light receiving structure receives 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 landing door of the floor where the light receiving structure is positioned is a target landing door capable of being opened safely. Illustratively, if the car stops at the flat position of the 5 th floor, the light emitted by 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 landing doors of the 5 th floor and the 6 th floor are target landing doors capable of being safely opened. If the cage 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 landing door of the 6 th floor is a target landing door which can be safely opened.
According to the elevator maintenance door opening method provided by the embodiment of the invention, when an elevator is stopped accidentally, the light source on the elevator car is controlled to be opened, the target hoistway door capable of being safely opened is determined based on the light emitted by the light source received by the light receiving structure in the elevator hoistway of each floor, when the elevator car is in a flat 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 elevator 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. The problem that maintenance personnel open the hall door under the condition that the position of the car is not clear and a falling accident occurs 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-sensitive switch, and the target hall door capable of being safely opened is determined based on light emitted from a light source received by the light receiving structure in the elevator shaft provided at each floor, and the method 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 capable of being opened safely.
The light sensitive switch senses light, which indicates that the light sensitive switch receives the light emitted by the light source, and the hall door of the floor where the light sensitive switch is located is a target hall door capable of being opened safely. In some embodiments of the present invention, the light-sensitive switch generates a switch signal when it senses light, and the hall door of the floor where the light-sensitive switch is located can be determined as the target hall door capable of being opened safely based on the received switch signal.
In some embodiments of the invention, the hall door of each floor is provided with an indicator light, and the indicator light of each floor is connected with the light-sensitive switch of the floor. When the light-sensitive switch senses light, the light-sensitive switch is closed to enable the indicating lamp to send a first indicating signal so as to remind maintenance personnel that the hall door of the floor is a target hall door capable of being opened safely. When the light-sensitive switch is not light-sensitive, the light-sensitive switch is turned on to enable the indicator lamp to send out a second indication signal so as to remind maintenance personnel that the hall door at the floor is forbidden to be opened. Illustratively, if the car stops at the leveling 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 to light, the indicating lamps on the hall doors of the 5 th floor and the 6 th floor emit first indicating signals (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 opened safely, the light-sensitive switches of the rest floors are not sensitive to light, and the indicating lamps of the rest floors emit second indicating signals (for example, emit red light) to remind the maintenance personnel that the hall doors of the rest floors are forbidden hall doors to be opened. If the car stops between the 5 th floor and the 6 th floor, the light-sensitive switch on the 6 th floor is sensitive to light, the indicator lamp on the hoistway door on the 6 th floor sends out a first indicator signal (for example, sends out green light) to remind the maintenance personnel that the hoistway door on the 6 th floor is a target hoistway door which can be safely opened, the light-sensitive switches on the rest floors are not sensitive to light, and the indicator lamps on the rest floors send out a second indicator signal (for example, sends out red light) to remind the maintenance personnel that the hoistway doors on the rest floors are forbidden to be opened.
In some embodiments of the present invention, each floor is provided with a voice alarm, and the elevator maintenance door opening method further comprises:
and receiving a detection signal output by the door lock key detection module, wherein the door lock key detection module is used for detecting whether a key is inserted into a door lock key hole of the hall door or detecting whether the key is rotated.
And when the detection signal indicates that the key is inserted into the key hole of the door lock or the key is rotated and the hall door is a non-target hall door, controlling the voice alarm to send out an alarm signal for forbidding opening the door.
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 key is inserted into a door lock key hole of the hall door or detecting whether the key is rotated. For example, the door lock key detection module may include a metal thimble, which normally maintains a constant potential, and when a maintenance worker inserts a key into a door lock key hole of the hall door, the metal thimble contacts the door lock, which causes the potential of the metal thimble to change, thereby detecting the key insertion. It should be noted that the metal thimble is an exemplary illustration and not a limitation for the door lock key detection module, and in other embodiments of the present invention, other structures may be adopted instead, for example, an infrared distance detection module and the like, and 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 as to detect the key insertion. When the situation that a key is inserted into a key hole of a door lock of a certain hall door and the hall door is a non-target hall door is detected, the voice alarm is controlled to send out an alarm signal for forbidding opening the door, and an alarm prompt is sent out when a maintenance worker inserts the key, so that the safety is further improved.
Fig. 1D is a schematic structural diagram of a door lock key detection module according to an embodiment of the present invention, fig. 1E is a schematic structural diagram of another door lock key detection module according to an embodiment of the present invention, and fig. 1F is a schematic structural diagram of another door lock key detection module according to an embodiment of the present invention, which is exemplarily shown in fig. 1D to 1F. Wherein, the plectrum needs to be rotated 180 degrees to open 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 forbidding opening the door, and sends out an alarm prompt before the maintenance personnel open 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 an infrared transmitting tube and an infrared receiving tube opposite to each other), and before the key is not rotated, the paddle is located between the infrared pair of tubes to shield the infrared light of the infrared transmitting tube, so that the infrared receiving tube cannot receive the infrared light. When the key is rotated by a certain angle (the angle is less than 180 degrees), the shifting piece is moved away from the position between the infrared pair tubes, the infrared receiving tubes receive infrared light, and the inductive switch is triggered.
As shown in fig. 1E, the inductive switch may include an inductive light source and a color sensor, the dial is coated with a color coating, before the key is not rotated, the dial faces the light source and the color sensor, and light emitted from the inductive light source is reflected by the color coating on the dial to form colored light, which is received by the color sensor. When the key is rotated by a certain angle (the angle is less than 180 degrees, at the moment, the door lock is not opened), the plectrum is moved away from the inductive switch, the color sensor cannot receive corresponding colored light, and the inductive switch is triggered.
As shown in fig. 1F, the inductive switch may include a magnet and a magnetic resistance element, the magnet is disposed on the blade, and the magnet is close to the magnetic resistance element before the key is turned. When the key is rotated by a certain angle (the angle is less than 180 degrees, and the door lock is not opened at the moment), the plectrum drives the magnet to move away from the magnetic resistance element, the magnetic field sensed by the magnetic resistance element is weakened, and the sensing switch is triggered.
Fig. 1G is a schematic view of a car at a leveling position, and fig. 1H is a schematic view of a car between two floors, as shown in fig. 1B and 1C, in an embodiment of the present invention, a light receiving structure includes a viewing hole opened in a hall door, and a target hall 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 shaft provided at each floor, including:
when the light emitted by the light source penetrates through the observation hole, the hall door of the floor where the observation hole is located is determined to be a target hall door capable of being opened safely.
For example, if the car stops at the leveling position of the 5 th floor, the light emitted by the light source can penetrate the observation hole of the 5 th floor and the observation hole of the 6 th floor, and the landing doors of the 5 th floor and the 6 th floor are target landing doors capable of being safely opened. If the cage is stopped between the 5 th floor and the 6 th floor, the light emitted by the light source can only penetrate through the observation hole of the 6 th floor, and the landing door of the 6 th floor is a target landing door which can be safely opened.
In the embodiment of the present invention, whether light emitted from the light source passes through the observation hole may be determined by observing the observation hole with human eyes or by using a light sensor, 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 is additionally arranged after the door plate is provided with the hole, and the surface of the glass is subjected to some special treatment (such as slight frosting) 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, and fig. 1J is a schematic view of a light barrier after rotating a certain angle, as shown in fig. 1I and fig. 1J, the light receiving structure further includes a paddle for unlocking and a light barrier, both the paddle and the light barrier are connected to a lock rod of a door lock, when a key is rotated, the lock rod, the paddle and the light barrier are driven to rotate, and the light barrier is triggered to move away from an observation hole before the paddle 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 source emits light which cannot penetrate through the observation hole. When the key is turned through an angle (e.g. 60 deg., which is less than 180 deg., when the door lock is not opened), the light barrier is removed from the viewing aperture and light from the light source can be transmitted through the viewing aperture. That is, before the door lock is opened by rotating 180 degrees during the process of turning the key, the maintenance personnel can see whether the light emitted by the light source can be seen through the observation hole, thereby determining whether the hall door is a target hall door which can be safely opened. If the light is visible, the key can be turned further to unlock and open the hall door. If the light is not visible, the key rotation is stopped.
Fig. 1K is a schematic view of the car in a flat position, and fig. 1L is a schematic view of the car between two floors, in the embodiment of the present invention, the distance between the car and the hoistway door is too narrow due to the space limitation between the car and the front wall of the hoistway, and the irradiation range of one light source is limited. Therefore, one light source may be added. The light emitted by the two light sources can only cover two light receiving structures at most, and 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 only when the elevator car is in the flat floor position (namely the elevator car is accurately stopped at a certain 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 different light emitting colors, for example, the light source on the top of the elevator car emits red light, if the light source is seen from the observation hole, the light source on the front wall of the elevator car emits green light, if the light source is seen from the observation hole, the light source is meant to go to the top of the elevator car from the entrance of the landing door, and if the light source is seen from the observation hole, the light source is meant to go to the elevator car from the entrance of the landing door, so that an operator can conveniently judge the relative position relationship of the elevator car and the operator in advance.
