Description

Technical Field

[0001] This invention relates to the field of escalator technology, and more specifically, to an escalator stopping system and an escalator system. Background Technology

[0002] In the implementation of escalator control, although real-time video from cameras near the escalator equipment can be accessed in the monitoring room, when a passenger is in danger on an escalator, the monitoring room staff may not be able to detect and intervene in time because they need to monitor multiple devices and multiple escalators simultaneously. If no one intervenes near the escalator where a passenger is in danger, the danger may escalate, potentially leading to personal injury to the passenger. Furthermore, when the monitoring room staff presses the emergency stop switch, the monitoring system can detect the change in the emergency stop button's status and remotely disconnect the safety circuit of the escalator control system, causing a power outage and an emergency stop to prevent further potential harm to passengers. However, adding additional safety contactors to the safety circuits of multiple escalator control systems increases the hardware cost of building the stopping system. Moreover, directly disconnecting the safety circuit causes a sudden stop of the escalator, increasing the possibility of other passengers falling and posing a potential safety hazard. Therefore, how to achieve safe and controllable escalator stopping effectively while reducing costs has become a pressing technical problem for those skilled in the art. Summary of the Invention

[0003] To address the aforementioned problems in the prior art, embodiments of the present invention propose an escalator stopping system and an escalator system, wherein the escalator stopping system has the advantages of achieving safe escalator stopping while maintaining low cost.

[0004] One aspect of the present invention provides an escalator stopping system, comprising: M sets of image acquisition devices, each corresponding to one of the M escalators and installed around the escalator; each set of image acquisition devices acquires real-time monitoring video of the monitoring area of ​​the corresponding escalator, where M is an integer greater than or equal to 1; a monitoring center-side control device, communicatively connected to all M sets of image acquisition devices, receiving the monitoring video from the M sets of image acquisition devices, identifying the monitoring video, and when a dangerous video is identified, displaying the dangerous video on the monitor of the monitoring center-side control device; the monitoring center-side control device includes an emergency stop button, and in response to a manual emergency stop operation of the emergency stop button, binding the escalator stop signal with the device identifier of the image acquisition device acquiring the dangerous video, generating binding information; and an escalator-side control device, communicatively connected to the monitoring center-side control device, generating a motor stop command upon receiving the binding information, and transmitting the motor stop command to the control motor of the escalator where the image acquisition device corresponding to the binding information is located, thereby controlling the control motor of the escalator where the image acquisition device corresponding to the binding information is located to stop running.

[0005] The escalator stopping system of this invention allows the escalator-side control device to directly control the escalator's control motor through the generation and transmission of signal commands to achieve a safe stop. Compared to the prior art, which involves connecting a contactor to the escalator-side safety circuit, this invention saves costs. Furthermore, this escalator stopping system, while cost-effective, offers a safer and more controllable stopping effect than cutting off the safety circuit. Specifically, it can proactively identify dangerous situations involving passengers on the escalator and display a pop-up notification to monitoring center staff. Staff can then remotely operate the emergency stop button, triggering a stop signal to control the corresponding escalator to a safe and reliable stop, enabling more timely stopping and reducing passenger safety risks. Additionally, this escalator stopping system is beneficial for retrofitting existing escalators. Without altering the existing system's hardware architecture, a communication connection is established between the escalator's control motor and the escalator-side control device. This communication connection includes signal and electrical connections, with the electrical connection including wire connections. This allows for safe stopping through the generation and transmission of control signal commands, simplifying the implementation of remote escalator control. Furthermore, the escalator-side control device of the present invention controls the operation of the escalator through a safety procedure rather than by directly cutting off the safety circuit to stop the escalator. Therefore, it can stop the escalator more safely and reliably, avoiding the risk of other passengers falling due to sudden stops.

[0006] In some embodiments, the monitoring center-side control device includes: a video recognition unit, communicatively connected to all M groups of image acquisition devices, receiving monitoring videos from the M groups of image acquisition devices, recognizing the monitoring videos, and determining dangerous videos that pose a hazard; and a monitoring center-side control unit, communicatively connected to the video recognition device, displaying the dangerous video in a pop-up window on the monitor of the monitoring center-side control unit when the dangerous video is recognized. The monitoring center-side control unit includes an emergency stop button, and in response to a manual emergency stop operation on the emergency stop button, binds the elevator stop signal with the device identifier of the image acquisition device that acquires the dangerous video, generates binding information, and communicates with the escalator-side control device to transmit the binding information to the escalator-side control device.

[0007] In some embodiments, the monitoring center-side control unit includes: a monitoring component, communicatively connected to the video recognition unit, which, when the dangerous video is recognized, displays the dangerous video on the monitor of the monitoring component, the monitoring component including an emergency stop button; and a monitoring center-side control component, communicatively connected to the monitoring component, which acquires the device identifier of the image acquisition device corresponding to the dangerous video, and, in response to a manual emergency stop operation on the emergency stop button, binds the elevator stop signal with the device identifier to generate binding information, and, communicatively connected to the escalator-side control device, transmits the binding information to the escalator-side control device.

[0008] In some embodiments, the escalator-side control device includes: an escalator-side control unit, which is communicatively connected to the monitoring center-side control device, and generates a motor stop command when receiving the binding information; and M escalator controllers, each communicatively connected to the escalator-side control unit and correspondingly connected to the control motors of the M escalators. The escalator controller corresponding to the control motor of the escalator where the image acquisition device corresponding to the binding information is located receives the motor stop command and transmits the motor stop command to the control motor to control the control motor to stop running. The communication connection includes a signal connection and an electrical connection, and the electrical connection includes a wire connection.

[0009] In some embodiments, the escalator-side control device includes: M safety relays, each of which switches between a first state and a second state; an escalator-side control unit, which is communicatively connected to both the monitoring center-side control device and the M safety relays; and M escalator controllers, which are communicatively connected to the M safety relays and to the control motors of the M escalators, respectively.

[0010] When the escalator-side control unit receives the binding information, it controls the safety relay connected to the escalator controller corresponding to the control motor of the escalator where the image acquisition device corresponding to the binding information is located to switch from the first state to the second state. When the safety relay switches from the first state to the second state, the escalator controller connected to the safety relay generates the motor stop command and transmits the motor stop command to the control motor of the escalator where the image acquisition device corresponding to the binding information is located, so as to control the control motor of the escalator where the image acquisition device corresponding to the binding information is located to stop running. The communication connection includes a signal connection and an electrical connection, and the electrical connection includes a wire connection.

[0011] In some embodiments, there are K escalator-side control units, each communicatively connected to the monitoring center-side control device. The K escalator-side control units are also communicatively connected to the M safety relays, where K is an integer greater than or equal to 2. The monitoring center-side control device transmits the binding information to the escalator-side control unit connected to the safety relay of the escalator controller corresponding to the control motor of the escalator where the binding information corresponds to the image acquisition device. When the escalator-side control unit receives the binding information, it controls the safety relay connected to the escalator controller corresponding to the control motor of the escalator where the binding information corresponds to the image acquisition device to switch from a first state to a second state. When the safety relay switches from the first state to the second state, the escalator controller connected to the safety relay generates a motor stop command and transmits the motor stop command to the control motor of the escalator where the binding information corresponds to the image acquisition device, thereby stopping the operation of the control motor of the escalator where the binding information corresponds to the image acquisition device.

[0012] In some embodiments, when the monitoring center-side control device identifies the dangerous video, the dangerous video pops up on the display of the monitoring center-side control device, and the voice component of the monitoring center-side control device emits a prompt tone.

[0013] In some embodiments, when the monitoring center-side control device identifies the dangerous video, the dangerous video pops up on the display of the monitoring center-side control device, and the lighting component of the monitoring center-side control device activates the flashing function.

[0014] In some embodiments, the emergency stop button is disposed adjacent to the display; or the emergency stop button is integrated into the display.

[0015] Another aspect of the present invention provides an escalator system comprising: M escalators and an escalator stopping system according to the above description, the escalator stopping system being used to control the M escalators, where M is an integer greater than or equal to 1.

[0016] The escalator system of this invention uses an escalator-side control device to directly control the escalator's motor through the generation and transmission of signal commands to achieve safe stopping. Compared with the prior art, which connects a contactor to the escalator-side safety circuit, this invention saves costs. Furthermore, the escalator stopping system of this invention achieves good safety performance at a low cost. Specifically, it can proactively identify dangerous situations of passengers on the escalator and display a pop-up notification to the monitoring center staff. Staff can remotely operate the emergency stop button, triggering a stop signal to control the corresponding escalator to stop urgently, enabling more timely stopping and reducing passenger safety. In addition, the escalator stopping system of this invention is also beneficial for retrofitting existing escalators. Without changing the existing system's hardware architecture, a communication connection is established between the escalator's motor and the escalator-side control device, achieving safe stopping through the generation and transmission of control signal commands, making the retrofitting and upgrading of existing escalators simpler. Moreover, the escalator-side control device of this invention uses program control for the escalator's motor, rather than power-off stopping. Therefore, after the escalator stops, the escalator-side control device can still control the escalator's motor, for example, by restarting it.

[0017] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0025] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention. Additionally, the various embodiments and technical features provided below can be combined with each other in any manner.

[0026] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. Furthermore, the terms "comprising," "including," etc., as used herein indicate the presence of said features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components. All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein should be interpreted in a manner consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0027] The following is for reference. Figure 1 An escalator stopping system 100 and an escalator system 1000 according to embodiments of the present invention are described.

[0028] like Figure 1 As shown, the escalator stopping system 100 according to an embodiment of the present invention includes M sets of image acquisition devices 1, a monitoring center side control device 2, and an escalator side control device 3.

[0029] Specifically, combined Figure 1 M sets of image acquisition devices 1 are installed around each of the M escalators 200, corresponding one-to-one. Each set of image acquisition devices 1 acquires real-time monitoring video of the monitoring area of ​​the corresponding escalator 200, where M is an integer greater than or equal to 1. The monitoring center control device 2 is communicatively connected to the M sets of image acquisition devices 1, receives the monitoring video from the M sets of image acquisition devices 1, and identifies the monitoring video. When a dangerous video is identified, a dangerous video pop-up window is displayed on the monitor 2211 of the monitoring center control device 2. The monitoring center control device 2 includes an emergency stop button 2212. In response to manual emergency stop operation of the emergency stop button 2212, the escalator stop signal is bound to the device identifier of the image acquisition device 1 that acquired the dangerous video, generating binding information. The escalator-side control device 3 is communicatively connected to the monitoring center control device 2. When it receives the binding information, it generates a motor stop command and transmits the motor stop command to the control motor of the escalator 200 where the image acquisition device 1 corresponding to the binding information is located, so as to control the control motor of the escalator 200 where the image acquisition device 1 corresponding to the binding information is located to stop running.

[0030] Here, communication connections can include signal connections and electrical connections, and electrical connections can include wire connections.

[0031] For example, each group of image acquisition devices 1 can be one image acquisition device 1 or multiple image acquisition devices 1.

[0032] For example, the control device 2 at the monitoring center can use an AI intelligent model to identify the monitoring video, thereby identifying the target video, which may be a dangerous video.

[0033] For example, when a hazard video pop-up appears on the display 2211 of the control device 2 at the monitoring center, staff can determine whether to manually stop the escalator 200 based on the danger shown in the video. If it is determined that an emergency stop is necessary, the staff can operate the emergency stop button 2212. Here, the emergency stop button 2212 can be a physical button or a touch button on the display screen. When the emergency stop button 2212 is a physical button, it can be pressed; when it is a touch button on the display screen, it can be clicked. Pressing or clicking the emergency stop button 2212 constitutes an emergency stop operation. When the emergency stop button 2212 is activated, a stop signal is generated.

[0034] It should be noted that the control motor will stop rotating after receiving a motor stop command, thereby stopping the elevator.

[0035] According to an embodiment of the present invention, the escalator stopping system 100 is communicatively connected to both the monitoring center control device 2 and the M groups of image acquisition devices 1, and can receive monitoring videos from the M groups of image acquisition devices 1. The monitoring videos are identified, and when a dangerous video is identified, it is displayed on the monitor 2211 of the monitoring center control device 2. The monitoring center control device 2 includes an emergency stop button 2212. By manually assessing the danger, the emergency stop button 2212 is operated. In response to the manual emergency stop operation of the emergency stop button 2212, the escalator stopping signal can be bound to the device identifier of the image acquisition device 1 that acquired the dangerous video, generating binding information. The escalator-side control device 3 is communicatively connected to the monitoring center control device 2, thus facilitating the receipt of the binding information. When the binding information is received, a motor stop command is generated and transmitted to the control motor of the escalator 200 where the image acquisition device 1 corresponding to the binding information is located, thereby stopping the corresponding escalator 200.

[0036] The escalator stopping system 100 of this invention uses the escalator-side control device 3 to directly control the control motor of the escalator 200 through the generation and transmission of signal commands to achieve a safe stop. Compared with the prior art, which connects a contactor to the escalator-side safety circuit, this invention can save costs. Furthermore, the escalator stopping system 100 of this invention, while cost-effective, provides a safer and more controllable stopping effect than cutting off the safety circuit. Specifically, it can proactively identify dangerous situations of passengers on the escalator 200 and display a pop-up notification to the monitoring center staff. Staff can then remotely operate the emergency stop button 2212 to generate a stopping signal, thereby controlling the corresponding escalator 200 to stop safely and reliably. This allows for more timely stopping and reduces the risk of injury to passengers. Furthermore, the escalator stopping system 100 of the present invention is also beneficial for the retrofitting of existing escalators. Without altering the existing system's hardware architecture, a communication connection is established between the control motor of the escalator 200 and the escalator-side control device 3. This communication connection includes signal and electrical connections, with the electrical connection including wire connections. This allows for safe escalator stopping through the generation and transmission of control signal commands, simplifying the implementation of remote escalator control. In addition, the escalator-side control device 3 of the present invention controls the escalator's operation through a safety program rather than directly cutting off the safety circuit to stop the escalator 200. Therefore, it can stop the escalator 200 more safely and reliably, avoiding the risk of other passengers falling due to sudden stops.

[0037] According to some embodiments of the present invention, such as Figure 1 As shown, the monitoring center-side control device 2 may include a video recognition unit 21 and a monitoring center-side control unit 22. The video recognition unit 21 is communicatively connected to all M groups of image acquisition devices 1, receives the monitoring videos from the M groups of image acquisition devices 1, identifies the monitoring videos, and determines dangerous videos that pose a hazard. The monitoring center-side control unit 22 is communicatively connected to the video recognition devices. When a dangerous video is identified, a dangerous video pop-up window is displayed on the monitor 2211 of the monitoring center-side control unit 22. The monitoring center-side control unit 22 includes an emergency stop button 2212. In response to a manual emergency stop operation on the emergency stop button 2212, the escalator stop signal is bound to the device identifier of the image acquisition device 1 that acquires the dangerous video, generating binding information. This binding information is then communicatively connected to the escalator-side control device 3 and transmitted to the escalator-side control device 3.

[0038] For example, the video recognition unit 21 can use an AI intelligent model to recognize surveillance videos, thereby identifying target videos, which may be dangerous videos.

[0039] The video recognition unit 21 and the monitoring center control unit 22 facilitate the following actions of the monitoring center control device 2: receiving monitoring videos from M groups of image acquisition devices 1, recognizing the monitoring videos, and when a dangerous video is identified, displaying the dangerous video on the monitor 2211 of the monitoring center control device 2, responding to the emergency stop operation of the emergency stop button 2212, binding the elevator stop signal with the device identifier of the image acquisition device 1 that acquired the dangerous video, generating binding information, and transmitting the binding information to the escalator side control device 3.

[0040] Here, the video recognition unit 21 and the monitoring center side control unit 22 can be independent components or integrated components.

[0041] According to some embodiments of the present invention, such as Figure 1 As shown, the monitoring center-side control unit 22 may include a monitoring component 221 and a monitoring center-side control component 222. The monitoring component 221 is communicatively connected to the video recognition unit 21. When a dangerous video is identified, a dangerous video pop-up window is displayed on the monitor 2211 of the monitoring component 221. The monitoring component 221 includes an emergency stop button 2212. The monitoring center-side control component 222 is communicatively connected to the monitoring component 221. It obtains the device identifier of the image acquisition device 1 corresponding to the dangerous video. In response to a manual emergency stop operation on the emergency stop button 2212, it binds the elevator stop signal with the device identifier to generate binding information. It is communicatively connected to the escalator-side control device 3 and transmits the binding information to the escalator-side control device 3.

[0042] The monitoring component 221 and the monitoring center control component 222 facilitate the following: when the video recognition unit 21 identifies a dangerous video, a dangerous video pop-up window is displayed on the monitor 2211 of the monitoring center control unit 22. In response to the manual emergency stop operation of the emergency stop button 2212, the elevator stop signal is bound to the device identifier of the image acquisition device 1 that acquires the dangerous video, generating binding information; the binding information is then transmitted to the escalator side control device 3.

[0043] Here, the monitoring component 221 and the monitoring center-side control component 222 can be independent components or integrated components.

[0044] According to some embodiments of the present invention, such as Figure 1As shown, the escalator-side control device 3 may include an escalator-side control unit 31 and M escalator controllers 32. The escalator-side control unit 31 is communicatively connected to the monitoring center-side control device 2. When it receives binding information, it generates a motor stop command. The M escalator controllers 32 are all communicatively connected to the escalator-side control unit 31 and are communicatively connected to the control motors of the M escalators 200 one-to-one. The escalator controller 32 corresponding to the control motor of the escalator 200 where the image acquisition device 1 corresponding to the binding information is located receives the motor stop command and transmits the motor stop command to the control motor to control the control motor to stop running. The communication connection includes signal connection and electrical connection, and the electrical connection includes wire connection.

[0045] The escalator-side control unit 31 and M escalator controllers 32 facilitate the following: receiving binding information, generating a motor stop command, and transmitting the motor stop command to the control motor of the escalator 200 where the image acquisition device 1 corresponding to the binding information is located.

[0046] Here, the escalator-side control unit 31 and the M escalator controllers 32 can be independent components or integrated components.

[0047] According to some embodiments of the present invention, such as Figure 1 As shown, the escalator-side control device 3 includes M safety relays 33, an escalator-side control unit 31, and M escalator controllers 32.

[0048] Specifically, each safety relay 33 switches between a first state and a second state; the escalator-side control unit 31 is communicatively connected to the monitoring center-side control device 2 and the M safety relays 33; the M escalator controllers 32 are communicatively connected to the M safety relays 33 and the control motors of the M escalators 200 respectively. When the escalator-side control unit 31 receives binding information, the safety relay 33 connected to the escalator controller 32 corresponding to the control motor of the escalator 200 containing the image acquisition device 1 corresponding to the binding information switches from the first state to the second state. When the safety relay 33 switches from the first state to the second state, the escalator controller 32 connected to the safety relay 33 generates a motor stop command and transmits the motor stop command to the control motor of the escalator 200 containing the image acquisition device 1 corresponding to the binding information, thereby stopping the operation of the control motor of the escalator 200 containing the image acquisition device 1 corresponding to the binding information. The communication connection includes signal connection and electrical connection, and the electrical connection includes wire connection.

[0049] For example, the first state of the safety relay 33 can be a closed state, and the second state can be an open state. When the escalator-side control unit 31 receives the binding information, the safety relay 33 connected to the escalator controller 32 corresponding to the control motor of the escalator 200 where the image acquisition device 1 corresponding to the binding information is located switches from the closed state to the open state. When the safety relay 33 is open, the escalator controller 32 connected to the safety relay 33 generates a motor stop command and transmits the motor stop command to the control motor of the escalator 200 where the image acquisition device 1 corresponding to the binding information is located, thereby controlling the motor to stop the escalator 200.

[0050] By using M safety relays 33, escalator-side control units 31, and M escalator controllers 32, the escalator-side control device 3 can easily achieve the following: receiving binding information, generating a motor stop command, and transmitting the motor stop command to the control motor of the escalator 200 where the image acquisition device 1 corresponding to the binding information is located. This allows the escalator-side control device 3 to directly control the escalator's control motor through the generation and transmission of signal commands to achieve safe escalator stopping, thereby saving costs.

[0051] According to some embodiments of the present invention, there can be K escalator-side control units, each of which is communicatively connected to the monitoring center-side control device. The K escalator-side control units are communicatively connected to M safety relays, where K is an integer greater than or equal to 2. Specifically, the monitoring center-side control device transmits binding information to the escalator-side control unit connected to the safety relay connected to the escalator controller corresponding to the control motor of the escalator where the image acquisition device corresponding to the binding information is located. When the escalator-side control unit receives the binding information, it controls the safety relay connected to the escalator controller corresponding to the control motor of the escalator where the image acquisition device corresponding to the binding information is located to switch from a first state to a second state. When the safety relay switches from the first state to the second state, the escalator controller connected to the safety relay generates a motor stop command and transmits the motor stop command to the control motor of the escalator where the image acquisition device 1 corresponding to the binding information is located, thereby controlling the control motor of the escalator 200 where the image acquisition device 1 corresponding to the binding information is located to stop operating.

[0052] It should be noted that the M safety relays can be evenly distributed among the K escalator-side control units, meaning each escalator-side control unit controls M / K relays, where M is an integer multiple of K. In some examples, M is 2 or 4 times K. Alternatively, the M safety relays can not be evenly distributed among the K escalator-side control units. For example, among the K escalator-side control units, the first escalator-side control unit controls i safety relays, the second escalator-side control unit controls j safety relays, the rth escalator-side control unit controls a safety relays, ..., the Kth escalator-side control unit controls b safety relays, where r is an integer greater than or equal to 1 and less than K, and i + j + a + ... + b = M, where i, j, a, ..., b are all integers greater than or equal to 1.

[0053] This allows for an increase in the number of escalators that can be controlled without affecting the response speed when controlling the escalators.

[0054] According to some embodiments of the present invention, when the monitoring center control device 2 identifies a dangerous video, a dangerous video pop-up window is displayed on the display 2211 of the monitoring center control device 2, and the voice component of the monitoring center control device 2 emits a prompt tone. It is understood that the voice component facilitates the emission of prompt tones, thereby more clearly reminding staff to pay attention to the dangerous video pop-up window.

[0055] According to some embodiments of the present invention, when the monitoring center control device 2 identifies a dangerous video, a dangerous video pop-up window is displayed on the monitor 2211 of the monitoring center control device 2, and the lighting component of the monitoring center control device 2 activates its flash function. It is understood that the lighting component facilitates the activation of the flash, thereby more clearly reminding staff to pay attention to the dangerous video pop-up window.

[0056] According to some embodiments of the present invention, such as Figure 1 As shown, the emergency stop button 2212 is positioned adjacent to the display 2211; or the emergency stop button 2212 is integrated into the display 2211. This allows staff to promptly operate the emergency stop button 2212 when the operator determines it is necessary.

[0057] According to some embodiments of the present invention, a safety interface is provided on the escalator-side control unit 31, and a safety interface is provided on each escalator controller 32. The escalator-side control unit 31 and each escalator controller 32 communicate through the safety interface. The safety interface on the escalator-side control unit 31 and the safety interface on each escalator controller 32 both conform to the SIL2 level in the safety integrity class.

[0058] like Figure 1As shown, the escalator system 1000 according to an embodiment of the present invention includes M escalators 200 and an escalator stopping system 100 as described above. The escalator stopping system 100 is used to control the M escalators 200, where M is an integer greater than or equal to 1.

[0059] According to an embodiment of the present invention, the escalator system 1000 is communicatively connected to the monitoring center control device 2 and the M groups of image acquisition devices 1, and can receive the monitoring videos from the M groups of image acquisition devices 1. The monitoring videos are identified, and when a dangerous video is identified, the dangerous video is displayed on the monitor 2211 of the monitoring center control device 2. The monitoring center control device 2 includes an emergency stop button 2212. By manually judging the danger, the emergency stop button 2212 is operated. In response to the manual emergency stop operation of the emergency stop button 2212, the escalator stop signal can be bound to the device identifier of the image acquisition device 1 that acquired the dangerous video, generating binding information. The escalator side control device 3 is communicatively connected to the monitoring center control device 2, thereby facilitating the receipt of the binding information. When the binding information is received, a motor stop command is generated and transmitted to the control motor of the escalator 200 where the image acquisition device 1 corresponding to the binding information is located, thus stopping the corresponding escalator 200.

[0060] The escalator system 1000 of this invention uses an escalator-side control device 3 to directly control the control motor of the escalator 200 through the generation and transmission of signal commands to achieve safe stopping. Compared with the prior art, which connects a contactor to the escalator-side safety circuit, this invention can save costs. Furthermore, the escalator stopping system 100 of this invention achieves good safety performance at a low cost. Specifically, it can proactively identify dangerous situations of passengers on the escalator 200 and display a pop-up notification to the monitoring center staff. Staff can remotely operate the emergency stop button 2212, triggering a stop signal to control the corresponding escalator 200 to stop urgently, enabling more timely stopping and reducing passenger safety. In addition, the escalator stopping system 100 of this invention is also beneficial for retrofitting existing escalators. Without changing the existing system's hardware architecture, a communication connection is established between the control motor of the escalator 200 and the escalator-side control device 3, achieving safe stopping through the generation and transmission of control signal commands, making the retrofitting and upgrading of existing escalators simpler.
