Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. The step numbers in the following embodiments are set only for ease of explanation, and there is no limitation on the order between the steps. The execution order of each step in the embodiments can be adaptively adjusted according to the understanding of those skilled in the art.

[0053] In the description of this invention, "multiple" means two or more. The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or the order of the indicated technical features. Furthermore, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art.

[0054] Reference Figure 1 This invention provides an escalator maintenance and testing system, comprising:

[0055] The escalator status acquisition module is used to communicate with the target escalator system to obtain the escalator's operating status; the safety switch triggering module is used to trigger the safety switch of the target escalator system and obtain the safety switch's action status.

[0056] The visual recognition module is used to identify the motor vibration amplitude and cabinet cleanliness of the target escalator system.

[0057] The data processing module is used to control the safety switch triggering module and the visual recognition module to start sequentially according to the escalator's operating status. It also obtains the action status feedback from the safety switch triggering module and the motor vibration amplitude and cabinet cleanliness feedback from the visual recognition module. Then, it determines the maintenance status score of the target escalator system based on the action status, motor vibration amplitude, and cabinet cleanliness.

[0058] Specifically, the escalator maintenance and detection system of this invention is independent of the escalator's drive and control system. It is used to automatically implement some maintenance and detection functions, reduce the workload of maintenance personnel, improve maintenance efficiency, and accurately provide a visualized maintenance status score. The escalator status acquisition module communicates with the target escalator system, receiving information such as the escalator's operating status and fault codes transmitted by the target escalator system. The safety switch triggering module triggers the safety switches of the target escalator system and acquires the operating status of the safety switches. The visual recognition module can be installed in the upper machine room of the escalator to identify and acquire information such as the motor vibration amplitude of the drive motor and the cleanliness of the control cabinet. The data processing module calculates the failure rate of the safety switches based on their operating status and determines the maintenance status score of the target escalator system by combining the motor vibration amplitude and cabinet cleanliness. This invention uses a safety switch triggering module to obtain the operating status of the safety switch, which can accurately detect whether each safety switch in the target escalator system is working properly. By using a visual recognition module to obtain the motor vibration amplitude and cabinet cleanliness, the operating status of the drive motor and the environmental condition of the control cabinet can be accurately assessed. The maintenance status score of the target escalator system can be accurately obtained without manual operation, thus improving the efficiency of escalator maintenance and inspection.

[0059] As an optional implementation, the escalator status acquisition module specifically includes:

[0060] A communication unit is used to communicate with the target escalator system;

[0061] The operation status acquisition unit is used to acquire the escalator's operation status.

[0062] The fault code acquisition unit is used to acquire the fault code of the target escalator system when the safety switch triggering module triggers the safety switch.

[0063] Reference Figure 2 As an optional implementation, the safety switch triggering module includes a baffle driving unit, a baffle action unit, a switch baffle unit, and a safety switch detection unit. The output shaft of the baffle driving unit is drivenly connected to the baffle action unit. The baffle action unit is drivenly connected to the safety switch through the switch baffle unit. The safety switch detection unit is electrically connected to the safety circuit of the target escalator system. The baffle driving unit is used to drive the switch baffle unit to act under the control of the data processing module, thereby triggering the corresponding safety switch to perform a switching action. The safety switch detection unit is used to detect whether the safety circuit is disconnected when the safety switch is triggered, thereby determining the operating state of the safety switch.

[0064] Specifically, the safety switch trigger module is an electromechanical combination structure. Since the installation positions of safety switches in escalator systems are different, the mechanical structures of the corresponding safety switch trigger modules are not exactly the same. However, their principle is the same: to trigger the safety switch to act by generating displacement through external force, thereby achieving the purpose of cutting off the safety circuit of the escalator system.

[0065] like Figure 3 As shown, the baffle actuation unit includes a spring assembly 11, an electromagnetic induction assembly 12, and a push rod 13. The electromagnetic induction assembly 12 is electrically connected to the baffle drive unit. When the baffle drive unit outputs voltage, the electromagnetic induction assembly 12 generates an induced magnetic field, thereby pushing the push rod 13 to actuate; when the baffle drive unit stops outputting voltage, the push rod 13 will self-reset under the force of the spring assembly 11. Figure 3 It can be seen that after the electromagnetic induction component 12 is energized, the push rod 13 moves downward to pull the switch baffle unit 20 to press the contact 31 of the safety switch 30, thereby realizing the switch action.

[0066] The function of the switch baffle unit is to extend the contact range of the safety switch contacts. The switch baffle unit is fixedly connected to the push rod of the baffle action unit. The baffle action unit can drive the switch baffle unit to move by pushing and pulling after being energized, thereby generating displacement to trigger the safety switch.

[0067] Safety switches are mainly used for safety monitoring of different components of escalators and elevators. When the safety switch trigger module is displaced, the contacts of the safety switch actuate, thereby cutting off the power supply in the escalator system control circuit and providing circuit protection for the escalator system. Safety switches are usually placed in critical parts of the escalator. Among them, the national standard requires comb tooth protection switches, handrail belt entrance protection switches, step chain breakage protection switches, and step sagging protection switches, etc. A series of normally closed contacts of safety switches are connected in series to form a safety circuit. The end of the safety circuit is connected to the escalator main control board or safety relay. When the safety switch actuates, the safety circuit is broken. When the main control board receives the safety circuit break signal, it stops the output to the contactor and frequency converter, thereby achieving the purpose of stopping the escalator for protection.

[0068] The safety switch detection unit is used for point-to-point detection of the operation of safety switches. When a safety switch is activated, its state changes (from normally closed to normally open). The safety switch detection unit can determine that the safety switch has been activated when it detects a change in the voltage of the safety circuit. The main purpose of the safety switch detection unit is to detect the operation status of safety switches point-to-point and transmit the operation status of each safety switch to the data processing module.

[0069] The baffle drive unit provides power to the baffle actuation unit. The baffle drive unit consists of a power module, an output module, and a communication module. The power module supplies power to the baffle actuation unit. When an output module activates, it connects the power module to the electromagnetic induction component, causing the baffle actuation unit to move. The baffle drive unit contains several output modules, the number of which corresponds to the number of safety switch trigger modules. Different output modules are used to activate their respective safety switch trigger modules.

[0070] As an optional implementation, the visual recognition module specifically includes:

[0071] The first camera unit is used to acquire motor image information of the drive motor of the target escalator system under the control of the data processing module.

[0072] The second camera unit is used to acquire cabinet image information of the control cabinet of the target escalator system under the control of the data processing module.

[0073] The image analysis module is used to determine the vibration amplitude of the drive motor based on the motor image information, and to determine the cleanliness of the control cabinet based on the cabinet image information.

[0074] Specifically, the visual recognition module performs image recognition on the operating status of the drive motor during escalator operation to obtain the motor vibration amplitude, and simultaneously performs image recognition on the cleanliness of the control cabinet to obtain the cabinet cleanliness level. Image recognition can employ existing image recognition models and related image processing techniques, which are not the focus of this embodiment and will not be elaborated upon here.

[0075] As a further optional implementation, the data processing module includes:

[0076] The operation status judgment unit is used to control the safety switch trigger module to start when the escalator is in the stopped state, and to control the vision recognition module to start when the escalator is in the open state.

[0077] The first data acquisition unit is used to acquire the action status fed back by the safety switch triggering module and the fault code fed back by the fault code acquisition unit.

[0078] The second data acquisition unit is used to acquire the motor vibration amplitude and cabinet cleanliness fed back by the visual recognition module.

[0079] The maintenance status scoring unit is used to determine the switch failure rate of the safety switch based on the action status and fault codes. Then, it performs a weighted summation of the switch failure rate, motor vibration amplitude and cabinet cleanliness according to preset weights to obtain the maintenance status score of the target escalator system.

[0080] Specifically, the data processing module interacts with the target escalator system through the escalator status module to obtain the escalator's operating status.

[0081] When the target escalator is stopped, the safety switch trigger module is activated. It should be noted that upon initial use, the number of safety switches needs to be entered into the data processing module. Assuming an input of 20, the system will automatically detect the operational status of all 20 safety switches and compare their statuses with the fault codes obtained from the target escalator system to determine if each safety switch is operating normally. When the safety switch trigger module activates and the target escalator system provides a corresponding fault code, the corresponding safety switch is considered normal. When the safety switch trigger module activates but the target escalator system does not provide a corresponding fault code, the corresponding safety switch is considered abnormal. The failure rate is determined based on the percentage of abnormal safety switches out of the total number of safety switches.

[0082] When the target escalator is in the open state, the vision recognition module is activated to identify the vibration amplitude of the drive motor and the cleanliness of the control cabinet.

[0083] Once the safety switch triggering module and the visual recognition module have completed their work within a maintenance cycle, the data is sent to the data processing module. The maintenance status score of the target escalator system can be obtained by weighted summation.

[0084] In an optional embodiment, the maintenance status score can be calculated using the following formula:

[0085] Maintenance status score = 90 - failure rate × 70 - (motor vibration amplitude / preset vibration amplitude) × 20 + rack cleanliness × 10

[0086] The preset vibration amplitude can be manually set in advance, and the cabinet cleanliness is expressed as a percentage. When the cabinet cleanliness is 100%, it means that there is no garbage or dust accumulation inside the cabinet.

[0087] It should be noted that the total score for maintenance status in this embodiment of the invention is 100. Since the safety switch is used to protect the safety of passengers during daily operation, the total score for safety switch trigger detection is set to 70. The drive motor is a core component with a low failure rate, but if a failure occurs, it will lead to equipment damage or safety accidents. Therefore, the total score for drive motor vibration amplitude detection is set to 20. The control cabinet contains a large number of core components of the escalator system. If there is dust and garbage accumulation, it will cause abnormal heat dissipation of the control cabinet and cause system failure. Therefore, the total score for machine room cleanliness detection is set to 10.

[0088] Users can view the maintenance status score and corresponding deduction records through a mobile app, and promptly arrange manual repairs for any deducted items. Furthermore, the mobile app can record maintenance data throughout the entire lifecycle of the target escalator system, generating a maintenance status score trend chart.

[0089] As an optional implementation, the escalator maintenance and inspection system further includes:

[0090] The early warning module is used to generate corresponding early warning information based on the maintenance status score and preset score thresholds, and send the early warning information to the cloud platform or user terminal.

[0091] Specifically, when the maintenance status score is below 80 points, a corresponding early warning message is generated and sent to the cloud platform or user terminal so that relevant personnel can quickly carry out manual maintenance on the target escalator system.

[0092] The system structure and working principle of the embodiments of the present invention have been described above. It can be understood that the embodiments of the present invention obtain the action status of the safety switch through the safety switch trigger module, which can accurately detect whether each safety switch in the target escalator system is working properly. By obtaining the motor vibration amplitude and cabinet cleanliness through the visual recognition module, the operating status of the drive motor and the environmental condition of the control cabinet can be accurately assessed. The maintenance status score of the target escalator system can be accurately obtained without manual operation, which improves the efficiency of escalator maintenance and inspection.

[0093] Reference Figure 4 This invention provides a method for maintenance and testing of escalators, comprising the following steps:

[0094] S101. Obtain the escalator operating status of the target escalator system;

[0095] S102. The safety switch triggering module and the visual recognition module are started sequentially according to the escalator's operating status. The safety switch triggering module triggers the safety switch of the target escalator system and obtains the action status of the safety switch. The visual recognition module identifies the motor vibration amplitude and cabinet cleanliness of the target escalator system.

[0096] S103. Determine the maintenance status score of the target escalator system based on its operating status, motor vibration amplitude, and cabinet cleanliness.

[0097] As an optional implementation, the escalator maintenance and detection method further includes the step of obtaining the fault code of the target escalator system when the safety switch triggering module triggers the safety switch. This step is initiated sequentially by controlling the safety switch triggering module and the visual recognition module according to the escalator's operating status. Specifically:

[0098] When the escalator is in a stopped state, the safety switch trigger module is activated; when the escalator is in an open state, the visual recognition module is activated.

[0099] The step of determining the maintenance status score of the target escalator system based on its operating status, motor vibration amplitude, and cabinet cleanliness is as follows:

[0100] The failure rate of the safety switch is determined based on the operation status and fault codes. Then, the failure rate of the switch, the vibration amplitude of the motor, and the cleanliness of the cabinet are weighted and summed according to preset weights to obtain the maintenance status score of the target escalator system.
