Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The exiting method of the elevator maintenance mode can be applied to the application environment shown in fig. 1. In this application environment, elevator control module 101 may communicate with pit inspection module 102, hall call module 103, and hall lock signal module 104. Wherein the elevator control module 101 may be deployed on a server or terminal and based on the received information, determine whether to exit the elevator service mode. The terminal can be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers and portable wearable devices, and the server can be implemented by an independent server or a server cluster formed by a plurality of servers.
In one embodiment, as shown in fig. 2, there is provided an exit method of an elevator service mode, which is described by taking an example of the method applied to the elevator control module 101 in fig. 1, and includes the following steps:
As an example, the door lock state may include an open state and a closed state, the open time being a period of time during which the door lock is in the open state.
In practical application, the elevator bottom hall door is often provided with a corresponding door lock, and when the door lock corresponding to the elevator bottom hall door is in a disconnected state, the elevator can stop running and be overhauled. In this embodiment, the elevator control module may obtain a door lock state corresponding to a door lock of a hall door at the bottom of the elevator, and determine a corresponding disconnection time when the door lock is in a disconnection state. Specifically, for example, a hall door lock signal module may be preset on a door lock of a hall door at the bottom of an elevator, and the hall door lock signal module may be connected in series in a hall door lock loop at the bottom of the elevator, determine a door lock state of the hall door at the bottom of the elevator, and send the door lock state to an elevator control module, so that the elevator control module can obtain the disconnection time based on the time when the door lock is in the disconnection state.
And 202, if the disconnection time is less than the preset first time, generating a trigger signal for exiting the elevator maintenance mode.
As an example, the first time is the time required for the elevator bottom hall door to be opened to a preset opening distance when the door lock is in the disconnected state, and the preset opening distance is the distance through which the user can pass the elevator bottom hall door.
The trigger signal may prompt exiting the current elevator service mode. The elevator maintenance mode can be an elevator pit maintenance mode, and under the elevator pit maintenance mode, relevant maintenance equipment of an elevator enters a pit maintenance state, such as the stop of the elevator.
When the elevator pit is overhauled, the elevator pit often enters the elevator pit through the elevator bottom hall door, namely the elevator bottom hall door can be firstly opened to the preset opening distance of a user through the elevator bottom hall door, then the user enters the elevator pit through the opened elevator bottom hall door, the elevator bottom hall door is opened to the preset opening distance, and the corresponding opening time can be the first time.
In a specific implementation, after the elevator control module obtains the disconnection time, it can be determined whether the disconnection time is less than a preset first time. If the disconnection time is determined to be less than the preset first time, the elevator bottom landing door can be determined to lack enough time to be opened to the preset opening distance, the opening distance of the elevator bottom landing door is not enough for a user to pass through and enter the elevator pit, and therefore the elevator control module can ensure that no other user enters the elevator shaft again. Therefore, when the disconnection time is less than the preset first time, the elevator control module may generate a trigger signal to exit the elevator service mode.
And step 203, exiting the elevator maintenance mode based on the trigger signal.
After generating the trigger signal, the elevator control module may exit the elevator service mode based on the trigger signal.
In the embodiment, the door lock state corresponding to the door lock of the elevator bottom-layer landing door can be obtained, the disconnection time of the door lock state in the disconnection state is determined, and if the disconnection time is less than the preset first time, a trigger signal for exiting the elevator maintenance mode can be generated, wherein the first time is the time required by the elevator bottom-layer landing door to be opened to the preset opening distance in the disconnection state of the door lock, and the preset opening distance is the distance which a user can pass through the elevator bottom-layer landing door; and then the elevator service mode can be exited based on the trigger signal. In the embodiment, it can be determined that no user enters the hoistway currently by determining that the disconnection time of the door lock of the hoistway door at the bottom layer of the elevator is less than the first time, and the user exits the elevator maintenance mode based on the disconnection time, so that the condition that whether the user exits the hoistway door can be determined by installing an additional device at the bottom layer of the elevator is avoided, the maintenance cost of the elevator is effectively saved, and the configuration of the elevator is simplified.
And the door lock state of the elevator bottom hall door is easy to obtain, for example, the door lock state can be obtained by connecting a hall door lock signal module in series in the elevator bottom hall door lock loop, and the installation position of devices is not required to be added outside the elevator hall, so that redundant devices in the elevator hall of the building can be simplified, and the decorative effect is improved.
In one embodiment, the determining the off-time when the door lock state is in the off-state includes:
when the condition that the door lock state is switched from a closed state to an open state is detected, determining a first moment when the state switching occurs; when the condition that the door lock state is switched from the open state to the closed state is detected, determining a second moment when the state switching occurs; and determining the disconnection time of the door lock of the elevator bottom hall door according to the first time and the second time.
In a specific implementation, when the elevator is in a normal operation state, the door lock state corresponding to the elevator bottom hall door lock can be a closed state. When the overhaul of the elevator pit is finished, the user can close the door lock of the elevator bottom hall door to enable the elevator bottom hall door to be in a closed state. In order to trigger the elevator control module to generate trigger information for exiting the elevator maintenance mode, a user can change the door lock state of the elevator bottom hall door.
Specifically, when the door lock state is the closed state, the user may convert the door lock state of the door lock from the closed state to the open state by performing a preset operation on the door lock. The elevator control module may record a first time at which the state switch occurs when detecting that the state of the door lock is switched from the closed state to the open state. When the door lock state is the open state, the user can switch the door lock state of the door lock from the open state to the closed state by executing preset operation, and then the elevator control module can record the second moment when the door lock state is converted into the closed state again. After the first time and the second time are obtained, the elevator control module may determine the disconnection time of the door lock of the hall door at the bottom floor of the elevator according to the first time and the second time, for example, calculate a difference between the second time and the first time to obtain the disconnection time.
In the present embodiment, the first timing to switch from the closed state to the open state according to the door lock state; and determining the disconnection time of the door lock of the elevator floor hall door at the second moment when the door lock state is switched to the closed state, and providing a judgment basis for determining whether to exit the elevator maintenance mode.
In one embodiment, the acquiring the door lock state corresponding to the door lock of the elevator bottom hall door comprises:
and receiving the door lock state sent by the door lock hall door lock signal module.
The hall door lock signal module determines that the current door lock state is the off state when detecting that the switch of the door lock is turned off by the key.
In a specific implementation, the door lock state of the door lock can be controlled by inserting a key matched with the door lock into the door lock of the elevator basement hall door, for example, a switch of the door lock is turned off or a switch of the door lock is turned on.
A hall door lock signal module can be pre-configured in a door lock of a hall door at the bottom layer of the elevator, the hall door lock signal module can determine the state of the door lock based on the control of a key on the door lock, and after the state of the door lock is determined, the hall door lock signal module can send the state of the door lock to an elevator control module.
Specifically, when it is detected that the key turns off the switch of the door lock, it can be determined that the current door lock state is the off state. For example, the key can control the change of signals in the door lock loop by twisting the door lock, and the hall door lock signal module can be connected in series in the door lock loop, so that the door lock state can be determined in the process of controlling the door lock by the key and changing the door lock state.
In this embodiment, the door lock can be provided with a hall door lock signal module, the hall door lock signal module can determine the door lock state by detecting the action of the key control door lock and the door lock switch, and sends the door lock state to the elevator control module, so that the elevator control module can quickly and conveniently determine the door lock state, a judgment basis is provided for judging whether a trigger signal is generated, the door lock state is easy to determine, a complex device does not need to be added, and the elevator configuration is simplified.
In one embodiment, the key is used for acquiring a twisting torque when the door lock is twisted, when the twisting torque is greater than or equal to a preset torque threshold value, the door lock state of the door lock is determined to be an open state, a prompt audio is played, and when it is detected that the playing duration of the prompt audio reaches a preset playing duration, the prompt audio is stopped being played so as to prompt a user to switch the open state of the door lock to a closed state.
The prompt audio can be used for indicating a user to maintain the current disconnected state of the door lock; the preset playing time length may be greater than or equal to the second time, that is, the preset playing time length may be greater than or equal to the minimum time for which the door lock is in the off state.
In practical application, the key can have an unlocking torque detection function, and in the process that a user controls the door lock by using the key, the key can acquire the twisting torque when the door lock is twisted. After the torsion moment is obtained, the elevator control module can compare the currently obtained torsion moment with a preset moment threshold value, and when the torsion moment is smaller than the moment threshold value, the door lock state of the door lock can be determined to be a closed state.
When the torque moment is greater than or equal to the preset torque threshold value, the door lock state of the door lock can be determined to be the disconnected state, and then prompt information can be sent out, wherein the prompt information can be prompt audio, and certainly, other forms of prompt information can also be provided, such as vibration with set frequency. When the prompt information is prompt audio, the prompt audio can be continuously played to prompt a user that the door lock is in a disconnected state currently, and the disconnected state of the door lock is maintained in the playing process of the prompt audio. In one example, when the door lock of the elevator basement hall door is twisted by a key, the user can only disconnect the door lock without opening the elevator basement hall door.
In the process of playing the prompt audio, the key can acquire the playing time of the prompt audio. When the fact that the playing duration of the prompt audio reaches the preset playing duration is detected, the prompt audio can be stopped being played, and a user is prompted to switch the current state of the door lock to the closed state. For example, when it is detected that the torque reaches the preset torque threshold, the key may play the prompting audio and stop playing after continuing to play for a time period t1, and the user switches the current state of the door lock from the open state to the closed state within a time period t2 after the prompting audio stops.
In this embodiment, the key may obtain a torsional moment when the door lock is twisted, when the torsional moment is greater than or equal to a preset moment threshold value, it is determined that the door lock state of the door lock is the off state, and a prompt audio is played, when it is detected that the playing duration of the prompt audio reaches the preset playing duration, the prompt audio is stopped being played, a user can be prompted to switch different door lock states by controlling the key in time, a proper off time is obtained, and the elevator control module is triggered to generate a trigger signal.
In one embodiment, the generating a trigger signal for exiting the elevator service mode if the disconnection time is less than a preset first time includes:
and if the disconnection time is less than the preset first time and the disconnection time is greater than the preset second time, generating a trigger signal for exiting the elevator maintenance mode.
Wherein the second time is a minimum time for which the door lock is in the open state.
After the disconnection time corresponding to the door lock is obtained, the disconnection time can be compared with the preset first time and the preset second time. If the disconnection time is determined to be less than the first time, the elevator bottom landing door can be determined to lack enough time to be opened to a preset opening distance, the opening distance of the elevator bottom landing door is not enough for a user to pass through and enter an elevator pit, and therefore the elevator control module can ensure that no other user enters an elevator shaft again. For example, the first time may be set to 1 second.
However, in practical applications, there is a door lock open due to door lock chattering, and the state is switched from the closed state to the open state without artificial triggering. Based on this, after determining the off-time, the off-time may be compared with a preset second time, which may be a normal time when the door lock is in the off-state in case of user trigger, for example, the second time may be set to 300ms (milliseconds). After obtaining the second time, it may be determined whether the current off-time is greater than the second time.
If the disconnection time is determined to be greater than the second time and less than the first time, it may be determined that the disconnected state of the door lock is triggered by the user and no other user is currently reentering the elevator hoistway, and thus, a trigger signal to exit the elevator service mode may be generated.
In this embodiment, when the disconnection time is less than the preset first time and greater than the preset second time, the trigger signal for exiting the elevator maintenance mode can be generated, the disconnection of the door lock caused by misoperation such as door lock shake can be effectively identified, and the trigger signal is prevented from being generated by mistake.
In one embodiment, before the step of acquiring the state of the door lock corresponding to the door lock of the elevator basement hall door, the method further comprises the following steps:
determining whether the elevator is currently in an elevator maintenance mode; if the elevator is in the elevator maintenance mode currently, when the triggering operation of a calling button corresponding to the elevator bottom-layer landing door is detected, determining the duration time of the triggering operation; and when the duration reaches the preset duration, executing the step of acquiring the door lock state corresponding to the door lock of the elevator bottom hall door.
In practical application, due to different reasons, under the condition that the elevator maintenance mode does not need to be exited, the disconnection time corresponding to the door lock of the elevator bottom hall door may reach the preset first time, and corresponding trigger conditions can be preset in order to avoid mistakenly exiting the elevator maintenance mode.
Specifically, the elevator control module can determine whether it is currently in an elevator service mode. If the elevator control module is in the elevator overhaul mode, the user can execute corresponding triggering operation on the elevator calling button corresponding to the elevator bottom-layer landing door, and if the elevator control module detects the triggering operation on the elevator calling button corresponding to the elevator bottom-layer landing door when the elevator control module is in the elevator overhaul mode, the duration time corresponding to the triggering operation can be acquired. And when the duration time is determined to reach the preset duration time, the door lock state corresponding to the door lock of the elevator bottom hall door can be acquired, and whether the elevator overhaul mode can be exited or not is determined based on the door lock state.
For example, the hall call box corresponding to the hall door at the bottom layer of the elevator can be at least provided with a call button in the upward direction, and the hall call box can be internally provided with a hall call module for providing a call signal in the upward direction of the bottom layer of the elevator to the elevator control module. When detecting that the time length for pressing the elevator calling button in the upper direction by the user reaches preset time, for example, 3 seconds, the elevator control module can determine that the duration of the trigger operation reaches the preset time length, enter an elevator maintenance exit confirmation mode, and execute the step of acquiring the door lock state corresponding to the door lock of the elevator bottom-layer landing door.
In this embodiment, if the elevator is currently in the elevator maintenance mode, when the triggering operation of the elevator calling button corresponding to the elevator bottom-layer hall door is detected, the duration of the triggering operation is determined, and when the duration reaches the preset duration, the step of acquiring the door lock state corresponding to the door lock of the elevator bottom-layer hall door is executed, so that the elevator maintenance mode can be effectively prevented from being mistakenly exited, and the operation safety of a user in the elevator maintenance process is ensured.
In one embodiment, before the step of acquiring the state of the door lock corresponding to the door lock of the elevator basement hall door, the method further comprises the following steps:
acquiring a switch state corresponding to a pit maintenance switch in an elevator shaft; and when the switch state is a closed state, executing the step of determining whether the elevator is in an elevator maintenance mode currently.
As an example, a pit service switch may be provided in the elevator hoistway.
In practical application, a user can exit from an elevator maintenance mode after completing pit maintenance and exiting from an elevator shaft. To ensure that the user has exited the elevator hoistway, the user may switch the pit inspection switch from an open state at the time of inspection to a closed state, e.g., to adjust the state of the pit inspection switch from "inspection" to "normal" before leaving the elevator hoistway. In the elevator maintenance process, the elevator control module can acquire the switch state corresponding to the pit maintenance switch, and when the switch state is detected to be the closed state, the elevator control module can preliminarily judge that the user in the elevator shaft exits, so that the door lock state corresponding to the door lock of the elevator bottom hall door can be further acquired.
In the embodiment, the step of determining whether the elevator is in the elevator maintenance mode at present is executed again by acquiring the switch state corresponding to the pit maintenance switch in the elevator shaft and when the switch state is the closed state, so that the user can be further ensured to quit the elevator shaft, and the operation safety is improved.
In order to enable those skilled in the art to better understand the above steps, the following is an example to illustrate the embodiments of the present application, but it should be understood that the embodiments of the present application are not limited thereto.
As shown in fig. 3, in the concrete implementation, after entering the elevator pit maintenance mode, if the user wants to exit the elevator pit maintenance mode, before exiting the elevator shaft, the user can control the pit maintenance module to reset the elevator pit maintenance switch, so that the on-off state of the pit maintenance switch is switched from the maintenance state to the normal state, and the elevator pit maintenance module can send a corresponding signal to the elevator control module.
After exiting the elevator shaft, the user can press the upward elevator calling button corresponding to the elevator bottom hall door for a long time for 3s or more to enter an exit confirmation mode of elevator pit maintenance, and at the moment, a prompt lamp in the upward elevator calling button can be in a flashing state to prompt the user that the user currently enters the mode.
After entering the exit confirmation mode, the user can rotate the door lock by the key matched with the door lock of the elevator bottom hall door, but does not open the door. This key has the moment of lock detection function of unblanking, and the user uses the key to twist reverse the in-process of lock, and the key can acquire corresponding torsion moment to compare torsion moment with predetermined moment threshold value, when torsion moment reached the moment threshold value, the lock switch disconnection, the lock is in the off-state, and the key can send the suggestion audio frequency this moment, and continuously plays. When the playing time reaches t1 time, the prompt audio is stopped. After the audio prompt ceases, the user may reset the door lock switch from the open state to the closed state at time t 2.
In the above process, the time when the door lock is in the open state is T1+ T2 ═ T. After receiving the change condition of the state of the door lock, the elevator control module can record the disconnection time T and the confirmation times and judge whether the condition that T2 is more than T and less than T1 is met (namely whether the disconnection time is more than a preset second time and less than a preset first time), wherein T2 is the minimum time for the door lock to be in the disconnection state, and T1 is the time required for the elevator bottom hall door to be opened to a preset opening distance when the door lock is in the disconnection state).
If not, judging whether the current confirmation times are less than the preset times, for example, whether N is less than 3, if so, retrying; otherwise, the current flow is ended. If the condition that T2 is more than T and less than T1 is met, the elevator control module can allow the elevator to exit from the pit maintenance state, the elevator calling button corresponding to the elevator bottom-layer landing door stops flashing, and the user can confirm that the elevator is exited from the pit maintenance state by pressing the elevator calling button in the upper direction corresponding to the elevator bottom-layer landing door for 3s or more.
It should be understood that, although the steps in the flowcharts of fig. 2 and 3 are shown in sequence as indicated by the arrows, the steps are not necessarily performed in sequence as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least a part of the steps in fig. 2 and 3 may include multiple steps or multiple stages, which are not necessarily performed at the same time, but may be performed at different times, and the order of performing the steps or stages is not necessarily sequential, but may be performed alternately or alternately with other steps or at least a part of the steps or stages in other steps.
