Attached Figure Description

[0087] Figure 1 This is a structural framework diagram of the multi-type elevator risk management system of the present invention. Detailed Implementation

[0088] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0089] To address the current issues of inability to monitor and control elevator risks in real time, and the inability to effectively record and manage multiple types of elevator risks, resulting in poor elevator usage and management, please refer to [link to relevant documentation]. Figure 1 This embodiment provides the following technical solution:

[0090] A multi-type elevator risk management system includes: a data acquisition module, a wireless communication module, and a risk management terminal.

[0091] By collecting data on the elevator's speed, load, and number of door openings and closings during operation, real-time elevator status data is determined to detect any abnormalities during operation. Once an abnormality is detected, an alarm will be issued immediately to remind the operator to take measures to prevent potential risks from turning into actual problems.

[0092] Among them, abnormal situations during elevator operation can reveal potential safety hazards. For example, if an elevator experiences a high frequency of abnormalities during periods of high usage, it may indicate that there is a problem with the elevator, i.e., abnormal elevator operation.

[0093] The data acquisition module is used to collect the elevator's speed, load, and number of door openings and closings during operation to determine the elevator's real-time operating status data.

[0094] In this embodiment, the data acquisition module includes:

[0095] The speed monitoring unit is used to monitor the speed of the elevator during operation.

[0096] Sensors are installed inside the elevator to monitor and continuously collect data on the elevator's speed during operation in real time.

[0097] It should be noted that the speed sensor is used to monitor and continuously collect data on the elevator's speed during operation in real time, thereby obtaining elevator speed data.

[0098] The load monitoring unit is used to monitor the load status during elevator operation;

[0099] Sensors are installed inside the elevator to monitor and continuously collect data on the load during elevator operation in real time, thereby obtaining elevator operation load data.

[0100] It should be noted that the load on the elevator during operation is monitored and continuously collected in real time by pressure sensors to obtain elevator operation load data.

[0101] The door opening and closing monitoring unit is used to monitor the number of times the elevator doors open and close during operation.

[0102] Sensors are installed inside the elevator to monitor and continuously collect data on the number of times the doors open and close during elevator operation in real time, thereby obtaining elevator operation and door opening / closing data.

[0103] It should be noted that the number of times the elevator doors open and close is monitored and continuously collected in real time through door magnetic sensors and U-shaped sensors to obtain elevator operation and door opening and closing data.

[0104] Among them, the door magnetic sensor is one of the key sensors used in elevators to detect the status of elevator doors. It is typically installed on the upper part of each elevator door and can sense the opening and closing status of the doors. When passengers enter or leave the elevator, the door magnetic sensor can detect this in a timely manner and monitor the opening and closing status of the elevator doors in real time. This not only ensures the normal operation of the elevator doors but also promptly issues alarm signals to remind passengers to pay attention to safety. By sensing the opening and closing status of the elevator doors and monitoring their operation in real time, the safe operation of the elevator doors and the safety of passengers are ensured.

[0105] Among them, the U-shaped sensor is a sensor that can detect the proximity of objects. In elevators, the U-shaped sensor is mainly used to detect the opening and closing status of the elevator doors. When passengers enter or leave the elevator, the U-shaped sensor can detect it in time and control the opening and closing of the elevator doors. The characteristic of this sensor is that it is non-contact, without direct contact with the elevator door, thus making it safer and more reliable during the opening and closing of the elevator doors. By detecting the proximity of objects non-contactly and controlling the opening and closing of the elevator doors, the accurate opening and closing of the elevator doors is ensured, preventing passengers or objects from being trapped.

[0106] Among them, the real-time status data of elevator operation is determined based on elevator operating speed data, elevator operating load data, and elevator door opening and closing data.

[0107] It should be noted that the real-time elevator operation status data includes elevator operating speed data, elevator operating load data, and elevator door opening and closing data.

[0108] The wireless communication module is used to transmit real-time elevator operation status data to the risk management terminal via a wireless network, thereby enabling the sharing of real-time elevator operation status data.

[0109] Specifically, the data acquisition module further includes:

[0110] The data acquisition frequency adjustment unit is used to extract speed data information during elevator operation, wherein the speed data information includes acceleration, speed change amplitude, and speed value;

[0111] The acceleration is compared with a preset acceleration threshold.

[0112] When the acceleration exceeds a preset acceleration threshold, the acceleration, velocity change amplitude, and velocity value contained in the velocity data information are extracted.

[0113] The speed operation coefficient is obtained by utilizing the acceleration, speed change amplitude, and speed value contained in the speed data information;

[0114] The speed operating coefficient is obtained by the following formula:

[0115] ;

[0116] Where R represents the speed operating coefficient; n represents the number of times speed data information is collected; a i Δv represents the acceleration corresponding to the i-th velocity data acquisition. i This represents the velocity change magnitude corresponding to the i-th velocity data acquisition; v idenoted as the speed value corresponding to the i-th speed data acquisition; t represents the time interval for speed data acquisition; θi represents the relative angle between the elevator running direction and the preset standard direction corresponding to the i-th speed data acquisition; a0 represents the preset acceleration threshold.

[0117] The speed operating coefficient is compared with a preset first speed operating coefficient threshold and a second speed operating coefficient threshold, and the data acquisition frequency of the speed data information is adjusted according to the comparison result.

[0118] The technical effects of the above solution are as follows: By monitoring the elevator's acceleration in real time and comparing it with a preset acceleration threshold, this solution can quickly respond to significant changes in the elevator's operating status. Once the acceleration exceeds the threshold, it means the elevator may be in an abnormal or critical operating state. At this time, comprehensive speed data information (including acceleration, speed change amplitude, and speed value) is immediately extracted, which helps to capture the elevator's dynamic behavior in a timely manner. This solution adopts a condition-triggered data acquisition mechanism, that is, the level of detail in data acquisition is increased only when the acceleration exceeds the threshold. This avoids unnecessary high-frequency data acquisition in non-critical states, thereby saving storage resources and processing time, and improving the overall efficiency of data acquisition. By calculating the speed operating coefficient R, this solution comprehensively considers multiple factors such as acceleration, speed change amplitude, speed value, data acquisition time interval, and the relative angle between the elevator's operating direction and the preset standard direction. This multi-dimensional evaluation method helps to more accurately identify potential faults or abnormal behaviors in elevator operation, providing strong data support for fault early warning and diagnosis. Based on the comparison results of the speed operating coefficient R with the preset first speed operating coefficient threshold and second speed operating coefficient threshold, this solution can dynamically adjust the data acquisition frequency. This means that when the elevator is running smoothly, the data collection frequency can be reduced to save resources; while during abnormal elevator operation or critical moments, the data collection frequency can be increased to obtain more detailed data for analysis and diagnosis. This adaptive adjustment mechanism helps improve the system's flexibility and response speed. By monitoring in real time and dynamically adjusting the data collection frequency, this solution can promptly detect and respond to abnormal situations during elevator operation, thereby effectively preventing potential safety hazards. This helps improve the overall stability and safety of the elevator system, ensuring the safety of passengers' lives and property.

[0119] In summary, this technical solution achieves significant improvements in performance indicators, including dynamic response capability, data acquisition efficiency, fault early warning and diagnosis capability, adaptive data acquisition frequency adjustment, and system stability and security.

[0120] Specifically, the speed operating coefficient is compared with a preset first speed operating coefficient threshold and a second speed operating coefficient threshold, and the data acquisition frequency of the speed data information is adjusted according to the comparison result, including:

[0121] The speed operating coefficient is compared with a preset first speed operating coefficient threshold and a preset second speed operating coefficient threshold;

[0122] When the speed operating coefficient is lower than the preset first speed operating coefficient threshold, the data acquisition frequency of the speed data information will not be adjusted.

[0123] When the speed operating coefficient is not lower than the preset first speed operating coefficient threshold, but is lower than the preset second speed operating coefficient threshold, the first acquisition frequency adjustment coefficient is obtained by using the acceleration, speed change amplitude and speed value contained in the speed data information.

[0124] The first sampling frequency adjustment coefficient is obtained by the following formula:

[0125] ;

[0126] Among them, K 01 This represents the first acquisition frequency adjustment coefficient; n represents the number of times the velocity data information is acquired; a i Δv represents the acceleration corresponding to the i-th velocity data acquisition. i This represents the velocity change magnitude corresponding to the i-th velocity data acquisition; v i θi represents the speed value corresponding to the i-th speed data acquisition; θi represents the relative angle between the elevator's running direction and the preset standard direction corresponding to the i-th speed data acquisition; a f Indicates the maximum magnitude of the change in acceleration; Δv b v represents the standard deviation of the velocity change amplitude corresponding to n velocity data collections; b This represents the standard deviation of the velocity values ​​corresponding to n velocity data collections.

[0127] The adjusted speed data acquisition frequency is obtained using the first acquisition frequency adjustment coefficient; wherein the adjusted speed data acquisition frequency is obtained using the following formula:

[0128] ;

[0129] Among them, F t This indicates the data acquisition frequency of the adjusted speed data; K 01 F0 represents the first acquisition frequency adjustment coefficient; F0 represents the data acquisition frequency of the speed data information before adjustment.

[0130] When the speed operating coefficient is not lower than the preset second speed operating coefficient threshold, the vibration frequency and vibration amplitude during elevator operation are retrieved, and the data acquisition frequency of speed data information is adjusted using the vibration frequency and vibration amplitude.

[0131] The technical effects of the above solution are as follows: By comparing the speed operating coefficient with preset first and second speed operating coefficient thresholds, this solution can dynamically adjust the data acquisition frequency according to different operating states. This ensures that excessive computing resources and storage space are not wasted when the elevator is running smoothly, while providing sufficiently detailed data support during abnormal elevator operation or critical moments. When the speed operating coefficient is between the first and second speed operating coefficient thresholds, the solution calculates the first acquisition frequency adjustment coefficient using multiple parameters such as acceleration, speed change amplitude, speed value, and the relative angle between the elevator's operation and the preset standard direction, and adjusts the data acquisition frequency accordingly. This multi-parameter comprehensive evaluation method helps to more accurately reflect the real-time operating status of the elevator, improving the accuracy and reliability of data acquisition. When the speed operating coefficient reaches or exceeds the second speed operating coefficient threshold, the solution not only adjusts the data acquisition frequency but also retrieves additional information such as vibration frequency and vibration amplitude during elevator operation. This helps to more comprehensively monitor the elevator's operating status, promptly detect potential faults or abnormal behaviors, and take corresponding measures for early warning or intervention, thereby improving fault early warning and response speed. This solution dynamically adjusts the data acquisition frequency, avoiding unnecessary high-frequency data acquisition in non-critical states, thus saving computing resources and storage space. Simultaneously, increasing the data acquisition frequency during critical states to obtain more detailed data also helps improve system resource utilization efficiency. The solution design offers high flexibility and scalability. By adjusting preset parameters such as acceleration thresholds, speed operating coefficient thresholds, and acquisition frequency adjustment coefficients, it can adapt to different elevator models and operating environments. Furthermore, the solution can add other monitoring parameters or adjust algorithms according to actual needs to meet more complex monitoring requirements.

[0132] In summary, this technical solution demonstrates significant technical effects in terms of dynamic optimization of data acquisition frequency, improvement of data acquisition accuracy, enhancement of fault early warning and response speed, efficient utilization of system resources, and system flexibility and scalability.

[0133] Specifically, when the speed operating coefficient is not lower than a preset second speed operating coefficient threshold, the vibration frequency and vibration amplitude during elevator operation are retrieved, and the data acquisition frequency of the speed data information is adjusted using the vibration frequency and vibration amplitude, including:

[0134] When the speed operating coefficient is not lower than the preset second speed operating coefficient threshold, the vibration frequency and vibration amplitude during elevator operation are retrieved;

[0135] Retrieve the acceleration, velocity change amplitude, and velocity value contained in the velocity data information;

[0136] The second acquisition frequency adjustment coefficient is obtained by combining the vibration frequency and vibration amplitude during elevator operation with the acceleration, velocity change amplitude and velocity value contained in the velocity data information;

[0137] The second sampling frequency adjustment coefficient is obtained by the following formula:

[0138] ;

[0139] Among them, K 02 This represents the second acquisition frequency adjustment coefficient; n represents the number of times the velocity data information is acquired; a i Δv represents the acceleration corresponding to the i-th velocity data acquisition. i This represents the velocity change magnitude corresponding to the i-th velocity data acquisition; v i θi represents the velocity value corresponding to the i-th velocity data acquisition; θi represents the relative angle between the elevator's running direction and the preset standard direction corresponding to the i-th velocity data acquisition; a0 represents the preset acceleration threshold; f i A represents the vibration frequency corresponding to the i-th velocity data acquisition; i f represents the vibration amplitude corresponding to the i-th velocity data acquisition; c Ai represents the vibration frequency reference value corresponding to the i-th velocity data acquisition; A0 represents the vibration amplitude reference value corresponding to the i-th velocity data acquisition.

[0140] The adjusted speed data acquisition frequency is obtained using the second acquisition frequency adjustment coefficient; wherein the adjusted speed data acquisition frequency is obtained using the following formula:

[0141] ;

[0142] Among them, F t This indicates the data acquisition frequency of the adjusted speed data; K 02 F0 represents the second acquisition frequency adjustment coefficient; F0 represents the data acquisition frequency of the speed data information before adjustment.

[0143] The technical effects of the above solution are as follows: When the speed operating coefficient reaches or exceeds the preset second speed operating coefficient threshold, the solution can automatically retrieve the vibration frequency and amplitude during elevator operation, and dynamically adjust the data acquisition frequency by calculating a second acquisition frequency adjustment coefficient, combining multiple parameters such as acceleration, speed change amplitude, and speed value. This dynamic adjustment mechanism allows the data acquisition frequency to more accurately reflect the actual operating state of the elevator, improving the relevance and effectiveness of data acquisition. By introducing vibration frequency and amplitude as reference factors for adjusting the data acquisition frequency, the solution can more comprehensively monitor the elevator's operating status. Vibration frequency and amplitude are important indicators reflecting the smoothness and safety of elevator operation, which helps to more accurately assess the elevator's operating status, thereby improving the accuracy and reliability of data acquisition. When abnormal elevator operation occurs, such as when the speed operating coefficient reaches or exceeds the second speed operating coefficient threshold, the solution can quickly respond and adjust the data acquisition frequency to obtain more detailed data for fault warning and diagnosis. By comprehensively analyzing multiple parameters such as acceleration, speed change amplitude, speed value, vibration frequency, and vibration amplitude, it is possible to more accurately determine whether the elevator has a fault or potential safety hazard, thereby taking timely intervention and handling measures. This solution dynamically adjusts the data acquisition frequency, avoiding unnecessary high-frequency data acquisition in non-critical states, thus saving computing resources and storage space. Simultaneously, increasing the data acquisition frequency during critical states to obtain more detailed data also helps improve system resource utilization efficiency. This resource allocation strategy allows the system to minimize resource consumption while ensuring data acquisition quality. The solution design offers high flexibility and scalability. By adjusting preset parameters such as acceleration threshold, speed operating coefficient threshold, vibration frequency reference value, vibration amplitude reference value, and acquisition frequency adjustment coefficient, it can adapt to different elevator models and different operating environments. Furthermore, this solution can add other monitoring parameters or adjust algorithms according to actual needs to meet more complex monitoring requirements.

[0144] In summary, this technical solution demonstrates significant improvements in dynamic adaptability of data acquisition frequency, data acquisition accuracy, fault early warning and diagnosis capabilities, efficient utilization of system resources, and system flexibility and scalability. These enhanced technical effects help to more accurately monitor the elevator's operating status, promptly identify and address potential safety hazards, thereby ensuring the safe operation of the elevator.
