Description

Technical Field

[0001] This disclosure relates to elevator systems, and more specifically to solutions for activating and / or deactivating temporary refuge spaces in elevator shafts. Background Technology

[0002] One of the main risks to personnel entering an elevator shaft for tasks such as maintenance is the risk of crushing. This risk exists both when personnel are at the top of the elevator car and in the pit. For example, the elevator car may be moved close to the top of the shaft with insufficient space for personnel, or the elevator car or counterweight may be moved close to the pit with insufficient space for personnel.

[0003] To provide sufficient refuge space for people in an elevator shaft, the dimensions of the pit depth and clearance height can be determined to ensure a permanent and adequate refuge space above and / or below the elevator car track. However, this requires increasing the depth / height of the elevator shaft, which may increase construction costs and other space-related expenses, or may be inconvenient from a construction point of view.

[0004] Technical measures can also be used to create refuge spaces in the elevator shaft. Elevator standard EN 81-21 recognizes two different solutions for creating artificial (non-permanent) refuge spaces: "movable stops" (e.g., rotatable buffers) and "pre-triggered stop systems" (e.g., safety device triggering devices located at fixed trigger points in the elevator shaft). However, even when the technical means are not activated, these solutions cannot prevent the presence of people in the danger zone.

[0005] The risk of crushing can also be completely eliminated. This is possible when it is impossible to enter the danger zone of an elevator shaft where the risk of crushing is present. For example, the elevator car may have a liftable car top or removable car floor or car wall sections, allowing elevator maintenance in the shaft to be performed from inside the elevator car without entering the shaft. However, these solutions are complex and / or expensive to implement. Summary of the Invention

[0030] The accompanying drawings are included to provide a further understanding of the invention and form part of this specification. The drawings illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention. In the drawings: Figure 1A A system according to an exemplary embodiment is shown.

[0031] Figure 1B A system according to another exemplary embodiment is shown.

[0032] Figure 1C A system according to another exemplary embodiment is shown.

[0033] Figure 1D An elevator system according to another exemplary embodiment is shown. Detailed Implementation

[0034] The solution presented in the following description provides a method for activating and / or deactivating temporary refuge spaces in elevator shafts. This solution is advantageous because it eliminates the risks associated with one or more people working in the elevator shaft.

[0035] Figure 1A A block diagram of a system for activating a temporary refuge space in an elevator shaft, according to an exemplary embodiment, is shown.

[0036] The system includes an elevator shaft access locking device 102, which controls access to a temporary refuge space via the elevator shaft access. The device 102 has a locked state and an unlocked state. In the locked state, it prevents opening of the elevator shaft access to the temporary refuge space; in the unlocked state, it allows opening of the elevator shaft access to the temporary refuge space. For example, the elevator shaft access may refer to one or more elevator landing doors. The system also includes a movement restriction device 104, which prevents the elevator car from moving within the elevator shaft. The device 104 operates between an inactive state and an active state. In the inactive state, it allows movement of the elevator car 110 throughout its operating range; in the active state, it prevents the elevator car from moving into the temporary refuge space. For example, the elevator shaft access locking device 102 may refer to a lock whose locked state can be remotely controlled.

[0037] The system also includes a refuge space control device 100 associated with the elevator shaft passage locking device 102 and the movement restriction device 104. The refuge space control device 100 can be configured to, in response to determining a temporary refuge space activation request, convert the state of the movement restriction device 104 to an active state and cause the state of the elevator shaft passage locking device 102 to an unlocked state, thereby enabling access to the temporary refuge space in the elevator shaft via the elevator shaft passage. In an exemplary embodiment, the movement restriction device 104 can be electrically connected to the elevator shaft passage locking device 102 such that when the state of the movement restriction device 104 is converted to an active state, the electrical connection causes the state of the elevator shaft passage locking device 102 to be converted to an unlocked state. In another exemplary embodiment, the movement restriction device 104 can be mechanically connected to the elevator shaft passage locking device 102, for example, via a linkage such that when the state of the movement restriction device 104 is converted to an active state, the mechanical connection causes the state of the elevator shaft passage locking device 102 to be converted to an unlocked state. For example, the refuge space control device 100 can refer to hardware and / or software elements that implement the functions associated with the refuge space control device 100.

[0038] In an exemplary embodiment, the refuge space control device 100 may be configured to determine a temporary refuge space activation request based on a signal from a manually operated device. For example, the manually operated device may refer to an emergency opening device (EOD) located near the elevator shaft passage or any other manually operable element.

[0039] In an exemplary embodiment, the refuge space control device 100 may be configured to receive temporary refuge space activation requests via a communication connection. For example, this implements a solution where the temporary refuge space activation request can be transmitted from a control entity (e.g., a cloud-based node or an application running on a mobile device) to the refuge space control device 100. It also implements a solution where maintenance personnel can use their mobile device to send the temporary refuge space activation request.

[0040] In an exemplary embodiment, the refuge space control device 100 may be configured to: expose a hidden manual operating device associated with a landing station in response to receiving a temporary refuge space activation request; receive a signal from the manual operating device 100, generated at the landing station by an action performed on the manual operating device by a person; and, in response to receiving the signal, convert the state of the movement restriction device 104 to an active state. This achieves a solution where the manual operating device can generally be hidden and is only exposed when an activation request is received. It also protects the manual operating device from damage and keeps it invisible when not in use.

[0041] In an exemplary embodiment, the refuge space control device 100 may be configured to: initiate a timer in response to receiving a temporary refuge space activation request; and, in response to receiving a signal only before the timer expires, change the state of the movement restriction device 104 to an active state. The use of a timer can provide additional safety features for entering the refuge space. For example, if a maintenance worker changes their mind after operating the manual control device for some reason and does not proceed further, the timer automatically ensures that the state of the movement restriction device 104 is changed only when the maintenance worker intends to enter the refuge space.

[0042] In an exemplary embodiment, the system also includes a short-range wireless reader 116, which is positioned at a landing site and configured to receive identification data provided by personnel at the landing site. The shelter control device 100 can be configured to determine a temporary shelter activation request based on the identification data from the short-range wireless reader. For example, the short-range wireless reader can be configured to receive the temporary shelter activation request via Bluetooth communication (or any other wireless transmission technology) or by reading an identifier associated with a radio frequency identification (RFID) tag. The shelter control device 100 can make the decision itself, or alternatively, it can send the identification data to a separate entity to receive verification of the identification data. The use of identification data enables a solution where access to the temporary shelter is restricted to authorized personnel only.

[0043] In an exemplary embodiment, the movement prohibition device 104 can selectively move between a retracted position providing an inactive state and a prohibition position providing an active state.

[0044] In an exemplary embodiment, when a temporary refuge space activation request is received by the refuge space control device 100, the following actions may occur: 1. The triggering device associated with the movement restriction device 104 moves to the protected position. This can be caused, for example, by the refuge space control device 100.

[0045] 2. When the triggering device is removed from the fully retracted state, the refuge space control device 100 that monitors the fully retracted state prevents the elevator from operating automatically (e.g., disconnects the safety output).

[0046] 3. When the triggering device is fully deployed, the refuge space control device 100, which monitors the fully deployed position, disables the power supply to the triggering device and enables the landing door (i.e., the elevator shaft passage) to be unlocked.

[0047] The movement of the elevator car and counterweight is now restricted by a pre-triggered stop system, and the user can open the elevator shaft passage leading to the work area. The passage door is prevented from opening until the triggering device has moved to the protected state. The triggering device can be prevented from being removed from the protected state until no personnel are detected in the danger zone, and the elevator shaft passage is prevented from opening. In an exemplary embodiment, the movement restriction device 104 may include a bidirectional safety device and an overspeed regulator, as well as a safety device triggering device and a fixed actuation point in the elevator shaft 112.

[0048] In an exemplary embodiment, the movement restriction device 104 may be mechanically connected to the elevator shaft lock device 102 such that when the state of the movement restriction device 104 is switched to the active state, the mechanical connection causes the state of the elevator shaft lock device 102 to be switched to the unlocked state. This enables a simple mechanical solution for switching the state of the elevator shaft lock device 102.

[0049] In an exemplary embodiment, the movement restriction device 104 may be electrically connected to the elevator shaft locking device 102, such that when the state of the movement restriction device 104 changes to an active state, the electrical connection causes the state of the elevator shaft locking device 102 to change to an unlocked state. In this exemplary embodiment, no mechanical connection is required between the movement restriction device 104 and the elevator shaft locking device 102. Instead, the state of the movement restriction device 104 may be detected, for example, based on sensor data, and the state of the movement restriction device 104 may then be controlled based on the sensor data.

[0050] In an exemplary embodiment, the temporary refuge space is located in the pit at the bottom of the elevator shaft. In another exemplary embodiment, the temporary refuge space is located at the top of the elevator car.

[0051] In an exemplary embodiment, the refuge space control device 100 can be configured to allow low-speed elevator operation when the movement restriction device is activated. For example, movement can be enabled via a manual user interface that can be operated by a user located in the temporary refuge space.

[0052] Figure 1B A block diagram of a system for activating a temporary refuge space in an elevator shaft, according to an exemplary embodiment, is shown.

[0053] The system includes an elevator shaft passage locking device 102 for controlling access to a temporary refuge space via an elevator shaft passage. The device 102 has a locked state and an unlocked state. In the locked state, it prevents opening of the elevator shaft passage leading to the temporary refuge space; in the unlocked state, it allows opening of the elevator shaft passage leading to the temporary refuge space. For example, an elevator shaft passage may refer to one or more elevator landing doors. The system also includes a movement prohibition device 104 for prohibiting movement of the elevator car within the elevator shaft. The device 104 operates between an inactive state and an active state. In the inactive state, it extends throughout the travel range of the elevator car 110, enabling movement of the elevator car 110; in the active state, it prevents the elevator car from entering the temporary refuge space. For example, the elevator shaft passage locking device 102 may refer to a lock whose locked state can be remotely controlled.

[0054] The system also includes a refuge space control device 100 associated with the elevator shaft passage locking device 102 and the movement prohibition device 104. The refuge space control device 100 can be configured to: in response to determining a temporary refuge space activation request, determine that the elevator car is in a position associated with the movement prohibition device 104, and transition the state of the movement prohibition device 104 to an active state 101. When the state of the movement prohibition device 104 has been transitioned, the movement prohibition device 104 can be configured to send an indication 103 to the refuge space control device 100 that its state has been transitioned to an active state. According to an embodiment, the transition of the state of the movement prohibition device causes a state transition of a safety contact belonging to the refuge space control device 100. In response to the indication 103, the refuge space control device 100 can be configured to cause the state of the elevator shaft passage locking device 102 to transition to an unlocked state, thereby enabling access to the temporary refuge space in the elevator shaft via the elevator shaft passage. For example, the refuge space control device 100 can refer to hardware and / or software elements that implement the functions associated with the refuge space control device 100.

[0055] Figure 1C A block diagram of a system for deactivating an activated temporary refuge space in an elevator shaft, according to an exemplary embodiment, is shown.

[0056] The system includes an elevator shaft passage locking device 102 for controlling access to a temporary refuge space via an elevator shaft passage. The device 102 has a locked state and an unlocked state. In the locked state, it prevents opening of the elevator shaft passage leading to the temporary refuge space. In the unlocked state, it allows opening of the elevator shaft passage leading to the temporary refuge space. The device is in the unlocked state when the temporary refuge space is activated. For example, an elevator shaft passage may refer to one or more elevator landing doors. The system also includes a movement prohibition device 104 for prohibiting movement of the elevator car within the elevator shaft. The device 104 is operable between an inactive state and an active state. In the inactive state, it allows movement of the elevator car throughout its travel range. In the active state, it prevents movement of the elevator car into the temporary refuge space. The device 104 is in the active state when the temporary refuge space is activated. The system also includes a refuge space deactivation device 106 for providing deactivation information associated with the temporary refuge space.

[0057] The system also includes a refuge space control device 100, which is associated with an elevator shaft passage locking device 102, a movement prohibition device 104, and a refuge space deactivation device 106. The refuge space control device 100 can be configured to: receive refuge space deactivation information from the refuge space deactivation device 106; determine that the elevator shaft passage is closed; change the state of the elevator shaft passage locking device 102 to a locked state; cause the movement prohibition device 104 to become inactive; and generate a signal indicating that the temporary refuge space has been deactivated.

[0058] In an exemplary embodiment, the deactivation information associated with the temporary shelter includes information about the presence of personnel in the temporary shelter. Shelter control device 100 is configured to determine that the temporary shelter is empty based on the shelter deactivation information. Shelter deactivation device 106 may include at least one of, for example, a camera, an infrared sensor, and a pressure pad arranged in the temporary shelter, for indicating the presence or absence of personnel in the temporary shelter. When using a camera, pressure pad, or infrared sensor, personnel in the temporary shelter can be detected automatically without any user action.

[0059] In an exemplary embodiment, the refuge space deactivation device 106 includes a first control function associated with a temporary refuge space and a second control function associated with the outside of the elevator shaft. For example, the first control function may refer to a pressure sensor, camera, manual switch, radio frequency (RF) reader, etc., that provides information related to the temporary refuge space. The refuge space control device 100 can be configured to: receive first temporary refuge space deactivation information from the first control function, which initiates the deactivation of the temporary refuge space; and receive second temporary refuge space deactivation information from the second control function, which confirms the deactivation of the temporary refuge space. In this example, deactivation can be divided into two stages, and two independent actions need to be identified before the temporary refuge space is deactivated. When the first action is initiated based on information associated with the temporary refuge space, the intention to deactivate the temporary refuge space can be seen. Then, the deactivation of the temporary refuge space is confirmed only when confirmation of deactivation is obtained externally. This provides verification that the temporary refuge space is empty.

[0060] In an exemplary embodiment, the refuge space control device 100 may be configured to: start a timer in response to receiving a first temporary refuge space deactivation message; determine whether a second temporary refuge space deactivation message has been received before the timer expires; and generate a signal indicating that the temporary refuge space has been deactivated only if the second temporary refuge space deactivation message has been received before the timer expires. The use of the timer provides additional security for deactivating the temporary refuge space. If the timer expires before receiving the second temporary refuge space deactivation message, the personnel in the temporary refuge space must restart the deactivation process.

[0061] In an exemplary embodiment, the refuge space deactivation device 106 includes a first control function associated with a temporary refuge space and a second control function associated with the outside of the elevator shaft. The refuge space control device 100 can be configured to: receive first temporary refuge space deactivation information from the second control function, the first temporary refuge space deactivation information initiating the deactivation of the temporary refuge space; receive second temporary refuge space deactivation information from the first control function; and determine that the temporary refuge space is empty based on the second temporary refuge space deactivation information. In other words, in this example, the deactivation of the temporary refuge space can begin outside the temporary refuge space. Then, after the temporary refuge space deactivation begins outside the temporary refuge space, the temporary refuge space is ensured to be empty based on the second temporary refuge space deactivation information from the first control function. Even if the temporary refuge space deactivation is initiated outside the temporary refuge space, it is still necessary to verify that the temporary refuge space is empty.

[0062] In an exemplary embodiment, the first control function may include at least one of the following: a manually operable control element configured to enable manual operation by a person; a short-range wireless reader configured to receive identification data provided by a person in the temporary shelter; a camera configured to provide an indication that a person is not present in the temporary shelter; an infrared sensor configured to provide an indication that a person is not present in the temporary shelter; and a pressure sensor configured to provide an indication that a person is not present in the temporary shelter. In other words, the first control function may refer to functions that require manual operation by maintenance personnel, such as a pit reset button, or a short-range wireless reader to which the maintenance personnel need to display their identification tag. Alternatively, the first control function may provide information automatically without (intentional) manual action by a person. For example, an infrared sensor, camera, or pressure sensor or pad may automatically provide the shelter control device 100 with an indication that a maintenance person has left the temporary shelter. This can then constitute first temporary shelter deactivation information.

[0063] In an exemplary embodiment, the second control function includes at least one of the following: a manually operable control element configured to be manually operated by a person at a landing; a short-range wireless reader configured to receive identification data provided by a person at a landing; a camera-based identification system; and a camera-based reader configured to read the identification data provided by a person at a landing. According to an embodiment, the second control function can be used to initiate the deactivation of a temporary refuge space or to confirm the deactivation of a temporary refuge space. In either case, various solutions and implementations can be used as the second control function. For example, a manually operable control element may refer to, for example, an emergency opening device (EOD) located near the elevator shaft passage. Alternatively, maintenance personnel may use a remotely readable tag (e.g., an RFID tag) to confirm that he / she has left the temporary refuge space. In an exemplary embodiment, the remotely readable tag can be used to provide deactivation information for initiating the deactivation of a temporary refuge space and deactivation information for confirming the deactivation of a temporary refuge space. Because the same remotely readable tag is used when entering and leaving the temporary shelter, confirmation is received that the same person is performing both actions.

[0064] In an exemplary embodiment, the movement restriction device 104 may be mechanically connected to the elevator shaft lock device 102 such that when the state of the movement restriction device 104 is changed to the inactive state, the mechanical connection causes the state of the elevator shaft lock device 102 to change to the locked state. This provides a simple mechanical solution for changing the state of the elevator shaft lock device 102.

[0065] In an exemplary embodiment, the movement restriction device 104 may be electrically connected to the elevator shaft locking device 102, such that when the state of the movement restriction device 104 changes to an inactive state, the mechanical connection causes the state of the elevator shaft locking device 102 to change to a locked state. In this exemplary embodiment, no mechanical connection is required between the movement restriction device 104 and the elevator shaft locking device 102. Instead, for example, the state of the movement restriction device 104 may be detected based on sensor data, and the state of the movement restriction device 104 may then be controlled based on the sensor data.

[0066] In an exemplary embodiment, the system may include, as described above... Figure 1A The system discussed for activating temporary refuge spaces in elevator shafts, and as per [the relevant regulations]... Figure 1C The system discussed is for deactivating activated temporary refuge spaces in elevator shafts.

[0067] Figure 1D An elevator system according to an exemplary embodiment is shown. The elevator system includes an elevator car 110 disposed in and movable within an elevator shaft 112. A temporary refuge space 108 may be arranged in the pit of the elevator shaft 112. In another exemplary embodiment, the temporary refuge space 108 may be arranged on top of the elevator car 110. A refuge space control device 100 is communicatively connected to a movement restriction device 104 and an elevator shaft passage locking device 102 associated with the elevator shaft passage 114 at a landing 118. The elevator system may also include a refuge space deactivation device 106 communicatively connected to the refuge space control device 100. In an exemplary embodiment, the elevator system may include only a device for activating… Figure 1A The system shown is a temporary refuge space 108 in the elevator shaft 112. In another exemplary embodiment, the elevator system may only include a function for deactivation. Figure 1C The system shown is an activated temporary refuge space 108 in the elevator shaft 112. In yet another exemplary embodiment, the elevator system may include two systems.
