[0002] Elevator landing doors are equipped with locks that require a special key to open. Currently, these keys are authorized for use and are typically kept by the elevator management office. Using a special key is a purely mechanical method of unlocking, which, in the absence of oversight, can be easily exploited by unqualified personnel using illegal keys. This can lead to unauthorized opening of elevator landing doors, a situation unavoidable with purely mechanical key unlocking methods, posing a significant safety hazard and resulting in frequent reports of injuries and fatalities.

[0003] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is prior art. Summary of the Invention

[0016] When the key recognition signal indicates that the authorized key has not been recognized, and the key sensing signal indicates that the authorized key has been detected, the elevator interrupts normal service and enters rescue or maintenance mode.

[0017] When the key sensing signal indicates that an abnormal key has been detected, the elevator will suspend all services and determine that the door was opened illegally.

[0018] When the key recognition signal indicates that the authorized key has not been recognized, and the key sensing signal indicates that the key has not been detected to open the landing door, the elevator provides normal service.

[0019] Optionally, after the elevator provides normal service, the following steps are also included:

[0024] Optionally, the authorized key is equipped with a corresponding authorized electronic tag, and the step of controlling the key sensing device to identify the key information includes:

[0025] The key sensing device is controlled to read the electronic tag of the key that opens the floor door according to a preset protocol;

[0026] When the electronic tag matches the authorized electronic tag, it is determined that the key sensing signal has detected the authorized key;

[0027] When the electronic tag does not match the authorized electronic tag, the key sensing signal is determined to be a detected abnormal key unlocking.

[0043] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0044] This invention provides a method for monitoring elevator landing door unlocking, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of an elevator landing door unlocking monitoring method according to the present invention.

[0045] In this embodiment, the elevator landing door unlocking monitoring method includes:

[0046] Step S10: Obtain a key recognition signal at a preset location, where an authorized key is placed;

[0047] In this embodiment, the preset location is generally set at the property management center, or it can be set in the security room. The authorized key is used to open the elevator landing door, generally called a special key. The authorized key opens the elevator landing door by unlocking the elevator landing door lock. Since the elevator has landing doors and car doors, if the elevator car is not level with the landing door after the special key opens the landing door, there is a risk of falling. A key recognition device is set at the preset location to detect whether the authorized key is located at the preset location. In this embodiment, the authorized key has an electronic tag. Optionally, the authorized key is equipped with a Radio Frequency Identification (RFID) tag, and the key recognition device is an RFID reader; alternatively, the authorized key is equipped with a positioning tag, such as an Ultra Wide Band (UWB) tag, and the key recognition device is a UWB recognition device. By controlling the key recognition device to identify the tag of the key placed at the preset location, a key recognition signal is obtained. Generally, the key recognition signal is either the authorized key is recognized or not recognized. Specifically, the key recognition device sends a detection signal and detects the key return signal. When no key return signal is detected, the key recognition signal is determined to be: the authorized key has not been recognized. When a key return signal is detected, the key identifier in the key return signal is compared with the identifier of the authorized key to obtain a comparison result. When the comparison result shows that the key identifier in the key return signal matches the identifier of the authorized key, the key recognition signal is determined to be: the authorized key has been recognized; when the comparison result shows that the key identifier in the key return signal does not match the identifier of the authorized key, the key recognition signal is determined to be: the authorized key has not been recognized.

[0048] Step S20: Detect the key sensor signal at the landing door position;

[0049] The "landing door position" here refers to the location of the elevator landing door. The key sensing device, positioned at each landing door, senses key information to obtain the key sensing signal. In this embodiment, since the elevator has multiple landing doors, a key sensing device can be installed at each landing door position. The number of key sensing signals is not limited. Furthermore, it should be noted that the key sensing device can be an RFID reader or a UWB identification device, specifically determined by the tag type of the authorized key. Additionally, in this embodiment, the execution order of steps S10 and S20 is not restricted; steps S10 and S20 can be executed simultaneously or sequentially.

[0050] Step S30: Determine the elevator landing door unlocking monitoring result based on the key identification signal and the key sensing signal.

[0051] In this embodiment, a pre-defined correspondence is established between the operating status and the combination of the key identification signal and the key sensing signal. The elevator door unlocking monitoring result is determined based on the key identification signal, the key sensing signal, and the correspondence. The elevator door unlocking monitoring result includes legitimate door opening behavior using an authorized key and illegal door opening behavior using an unauthorized key.

[0052] In this embodiment, by acquiring the key recognition signal at a preset position and the key sensing signal to detect the position of the landing door, it is possible to determine whether the key to open the landing door has left the preset position and whether the key is at the landing door. The elevator landing door unlocking monitoring result is determined based on the key recognition signal and the key sensing signal, thereby reducing the safety hazards caused by illegal opening of the landing door.

[0053] Furthermore, based on the first embodiment, a second embodiment of the elevator landing door unlocking monitoring method of the present invention is proposed, referring to... Figure 2 After the step of obtaining the key recognition signal at the preset location, the method further includes:

[0054] Step S101: When the key recognition signal indicates that the authorized key has been recognized, the elevator provides normal service;

[0055] Step S102: When the key recognition signal indicates that the authorized key has not been recognized, determine to execute the step of detecting the key sensing signal of the floor door position.

[0056] It should be noted that in this embodiment, after the execution of step S10, it is necessary to determine whether to trigger the execution of step S20 based on the key identification signal. When the key identification signal indicates that the authorized key has been identified, the execution step does not need to be triggered, but this does not prohibit the execution of step S20; step S20 can still be executed according to its preset detection frequency. In this embodiment, when the key identification signal indicates that the authorized key has not been identified, an alarm signal or reminder signal is sent to the alarm receiving terminal, and the step of detecting the key sensing signal at the floor door position is executed simultaneously. Normal service here refers to the elevator performing normal operating services, such as receiving call commands from each floor and operating according to the call commands. Furthermore, in other embodiments, steps S10 and S20 can be executed simultaneously.

[0057] In this embodiment, by detecting the key sensing signal based on the key recognition signal after obtaining the key recognition signal at the preset position, the response speed is improved, thereby reducing the risk caused by elevator operation after the landing door is opened.

[0058] Furthermore, based on the first or second embodiment, a third embodiment of the elevator landing door unlocking monitoring method of the present invention is proposed, referring to... Figure 3After the step of detecting the key sensing signal of the landing door position, the method further includes:

[0059] Step S201: When the key sensing signal is that an abnormal key is detected to unlock, or when the key sensing signal is that the authorized key is detected, the position signal of the floor door is obtained;

[0060] Step S202: Based on the position signal, control the warning device corresponding to the floor door position to issue a corresponding warning message.

[0061] Here, "abnormal key unlocking" refers to using an unauthorized key to open a landing door, i.e., a key other than the authorized key. The location signal is the landing door identifier, such as the first, second, and third floors. The specific floor where the unlocking action occurred is determined by identifying the location identifier corresponding to the landing door location, and in this embodiment, the time of the corresponding unlocking action is recorded. Based on the location signal, the warning device on the corresponding floor issues a corresponding message. The warning message varies depending on the situation. For example, when the key sensing signal detects abnormal key unlocking, the warning message is: "Unauthorized unlocking, shaft danger, please stop unlocking action, and stop elevator operation until authorized personnel handle the situation on-site." When the key sensing signal detects an authorized key, the warning message is: at least one of the following: current floor information, elevator operation information, reassurance message, and emergency voice message.

[0062] In this embodiment, the warning device corresponding to the landing door position is controlled by the position signal to issue a corresponding warning message, which can reduce the accidental risk caused by illegal unlocking and improve the safety of legally opening the landing door for rescue or maintenance.

[0063] Furthermore, based on any of the above embodiments, a fourth embodiment of the elevator landing door unlocking monitoring method of the present invention is proposed, referring to... Figure 4 The step of determining the elevator landing door unlocking monitoring result based on the key identification signal and the key sensing signal includes:

[0064] Step S31: When the key recognition signal indicates that the authorized key has not been recognized, and the key sensing signal indicates that the authorized key has been detected, the elevator interrupts normal service and enters rescue or maintenance mode.

[0065] It should be noted that when the key identification signal indicates that the authorized key has not been identified, and the key sensing signal indicates that the authorized key has been detected, it means that the landing door has been legally opened by the authorized key. This method of opening the landing door is generally for rescuing people trapped in the elevator or for elevator maintenance. Furthermore, it is necessary to determine whether the purpose of opening the door is to rescue people trapped in the elevator or to perform elevator maintenance, thereby determining the specific method of stopping the elevator. For example: when it is detected that people are trapped in the elevator, the power supply to the elevator traction machine is stopped; when it is detected that there are people in the elevator but there is no abnormality in the elevator, the car is controlled to move to the nearest floor or the floor whose door is opened by the authorized key. After leveling, the car door is opened, and the landing door of the nearest floor or the floor whose door is opened by the authorized key is also opened. A maintenance voice message is played to allow the people in the car to leave.

[0066] Step S32: When the key sensing signal indicates that an abnormal key has been detected, the elevator service is interrupted and illegal opening is confirmed.

[0067] Specifically, unauthorized opening here refers to opening the door with an unauthorized key. After confirming unauthorized opening, a corresponding alarm signal will be given via voice prompt, and the floor information of the floor where the unauthorized opening occurred, the opening time, etc. will be sent to the elevator management terminal via the network. Furthermore, an alarm can also be triggered.

[0068] Step S33: When the key recognition signal indicates that the authorized key has not been recognized, and the key sensing signal indicates that the key has not been detected to open the landing door, the elevator provides normal service.

[0069] In this embodiment, when the key identification signal indicates that the authorized key has not been identified, and the key sensing signal indicates that the key has not been detected to open the landing door, it is determined that there is no risk of the landing door being opened abnormally, thereby allowing the elevator to operate normally.

[0070] In this embodiment, the elevator landing door unlocking monitoring result is specifically determined by the key identification signal and the key sensing signal. This enables the execution of elevator control steps corresponding to the elevator landing door unlocking monitoring result when the door is opened with an authorized key or an unauthorized key. This reduces the risk of accidents caused by illegal unlocking while improving the safety of legally opening landing doors for rescue or maintenance.

[0071] Furthermore, after the elevator provides normal service, the following steps are also included:

[0072] Return to the step of obtaining the key recognition signal at the preset location.

[0073] Specifically, an interval time can be set. After the elevator operates normally, a corresponding first time is recorded, and a current second time is obtained. When the difference between the second time and the first time is greater than or equal to the interval time, the process returns to the step of obtaining the key recognition signal at the preset position. In other embodiments, after the elevator provides normal service, the process further includes: returning to the step of detecting the key sensing signal at the landing door position.

[0074] In this embodiment, by returning to the step of obtaining the key recognition signal at the preset position, the status of the door can be continuously monitored, thereby reducing the risk of accidents caused by unauthorized unlocking.

[0075] Furthermore, based on any of the above embodiments, a fifth embodiment of the elevator landing door unlocking monitoring method of the present invention is proposed, referring to... Figure 5 and Figure 6 A door lock opening rod 2 is provided at the door lock device 3 at the location of the landing door 1. The door lock opening rod 2 is rigidly connected to the lock hole 4. A key sensing device 5 is provided at the landing door location. An alarm 6 is connected to the key sensing device 5.

[0076] The step of detecting the key sensing signal at the location of the landing door includes:

[0077] Detect the rotational position of the door lock opening rod;

[0078] When the rotation position of the door lock opening rod deviates from the preset position, the key sensing device is controlled to identify the key information.

[0079] Furthermore, the key sensing device is located on one side of the top rod, and the preset position here is the position pre-set on the door lock opening top rod 4, specifically in this embodiment. It can be... Figure 5 and Figure 6 The position of the door lock opening rod 2 is the preset position. When the lock hole 4 rotates, it drives the door lock opening rod 4 to rotate, thereby triggering the key sensing device 5 to recognize key information. The mechanical structure in this embodiment only represents the specific implementation of the key sensing signal for detecting the landing door position. Other embodiments are also possible. In other embodiments, the key sensing device can also be set below the door opening counterweight of the landing door, and the key sensing device 5 is triggered to recognize key information based on the distance between the counterweight and the key sensing device. When the elevator car is not on the landing floor and the distance between the counterweight and the key sensing device is less than or equal to a preset counterweight distance threshold, the key sensing device 5 is controlled to recognize key information. Since the counterweight is an inherent device of the elevator, the cost of the technical solution of this application can be reduced, and false alarms can be avoided by combining it with the position of the elevator car.

[0080] In this embodiment, by detecting the rotational position of the door lock's door opening lever to trigger the key sensing device to recognize key information, false alarms caused by staff carrying the authorized key passing through the door can be avoided.

[0081] Furthermore, based on the fifth embodiment, a sixth embodiment of the elevator landing door unlocking monitoring method of the present invention is proposed, wherein the authorized key is equipped with a corresponding authorized electronic tag, and the step of controlling the key sensing device to identify the key information includes:

[0082] The key sensing device is controlled to read the electronic tag of the key that opens the floor door according to a preset protocol;

[0083] When the electronic tag matches the authorized electronic tag, it is determined that the key sensing signal has detected the authorized key;

[0084] When the electronic tag does not match the authorized electronic tag, the key sensing signal is determined to be a detected abnormal key unlocking.

[0085] The preset protocol here can be ISO / IEC 18000-6, which belongs to RFID technology, or IEEE 802.15.4, which belongs to UWB technology. Of course, this embodiment does not limit the type of preset protocol. In addition, when the electronic tag of the key to open the landing door cannot be read according to the preset protocol, it is determined that the key sensing signal has detected an abnormal key unlocking.

[0086] In this embodiment, the key sensing device reads the electronic tag of the key that opens the landing door according to a preset protocol, and determines whether it matches the authorized electronic tag to determine the sensing signal, thereby increasing the difficulty of opening the landing door with an illegal key and reducing the accidental risk caused by illegal unlocking.

[0087] Furthermore, this invention also proposes an elevator landing door unlocking monitoring device, which includes:

[0088] The identification module is used to acquire a key identification signal at a preset location, where an authorized key is placed.

The memory 1005 may be a high-speed random access memory (RAM) or a stable non-volatile memory (NVM), such as a disk drive. The user interface 1004 may be a sound player and display screen that issue warning messages to elevator users. Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0093] Those skilled in the art will understand that Figure 1 The structure shown does not constitute a limitation on the elevator and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0094] Furthermore, the elevator also includes: a key recognition device installed in a preset position and a key sensing device installed at the elevator landing door position. In addition, to realize the basic functions of the elevator, the elevator also includes: landing door, car door, car, car door knife, landing door counterweight, door lock opening rod, door lock, traction machine, elevator control box, industrial control computer, etc.

[0095] Furthermore, this invention also proposes a storage medium storing an elevator landing door unlocking monitoring program, which, when executed by a processor, implements the steps of any of the above-described embodiments of the elevator landing door unlocking monitoring method.

[0096] like Figure 7 As shown, the memory 1005, which serves as a storage medium, may include an operating system, a data storage module, a network interface module, a user interface module, and an elevator landing door unlocking monitoring program.

[0097] exist Figure 7In the elevator shown, the network interface 1003 is mainly used for data communication with other devices; the network interface 1003 can also communicate with the elevator control room; the processor 1001 and the memory 1005 in the elevator of the present invention can be installed in the elevator, and the elevator calls the elevator landing door unlocking monitoring program stored in the memory 1005 through the processor 1001 and executes the elevator landing door unlocking monitoring method provided in the embodiment of the present invention.
