BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 It is a structural framework diagram of the management system for multiple types of elevator risks of the present invention. DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] In order to solve the existing problem of not being able to monitor and control elevator risks in real time, and not being able to effectively record and manage multiple types of elevator risks, resulting in poor elevator use and management effects, please refer to Figure 1 , this embodiment provides the following technical solutions: A management system for multiple types of elevator risks includes: a data acquisition module, a wireless communication module and a risk management terminal.

[0020] Among them, by collecting the speed, load and number of door openings and closings during the operation of the elevator, the real-time status data of the elevator operation is determined in order to detect abnormal conditions during the operation of the elevator. 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.

[0021] Among them, abnormal conditions during the operation of an elevator can be used to discover potential safety hazards. For example, if an elevator has a higher frequency of abnormal conditions during a time period with higher frequency of use, this may mean that there is some problem with the elevator, that is, the elevator is operating abnormally.

[0022] The data acquisition module is used to collect the speed, load and number of door openings and closings during the operation of the elevator and determine the real-time status data of the elevator operation; In this embodiment, the data acquisition module includes: Speed ​​monitoring unit, used to monitor the speed of the elevator during operation; Install sensors inside the elevator to monitor and continuously collect the speed of the elevator in real time during operation, and obtain the elevator speed data; It should be noted that the speed sensor is used to monitor and continuously collect the speed of the elevator in real time during operation to obtain the elevator operation speed data.

[0023] Load monitoring unit, used to monitor the load condition during the operation of the elevator; Install sensors inside the elevator to monitor and continuously collect the load conditions of the elevator in real time during operation, and obtain the elevator operation load data; It should be noted that the load conditions during the operation of the elevator are monitored in real time and continuously collected through the pressure sensor to obtain the elevator operation load data.

[0024] The door opening and closing monitoring unit is used to monitor the number of door opening and closing times during the operation of the elevator; Install sensors inside the elevator to monitor and continuously collect the number of times the elevator door is opened and closed during operation in real time based on the sensors, and obtain elevator door opening and closing data; It should be noted that the door magnetic sensor and the U-shaped sensor are used to monitor and continuously collect the number of door openings and closings during the operation of the elevator in real time to obtain the elevator operation door opening and closing data.

[0025] Among them, the door magnetic sensor is one of the key sensors used to detect the status of the elevator door. It is usually installed on the upper part of the elevator door on each floor and can sense the opening and closing status of the elevator door. When passengers enter or leave the elevator, the door magnetic sensor can sense it in time and monitor the opening and closing status of the elevator door in real time. In this way, it can not only ensure the normal operation of the elevator door, but also send out alarm signals in time to remind passengers to pay attention to safety; by sensing the opening and closing status of the elevator door, the operation of the elevator door is monitored in real time to ensure the safe operation of the elevator door and the safety of passengers. Among them, the U-shaped sensor is a sensor that can sense whether an object is approaching or not. In elevators, the U-shaped sensor is mainly used to detect the opening and closing status of the elevator door. When passengers enter or leave the elevator, the U-shaped sensor can sense it in time and control the opening and closing operation of the elevator door. The characteristic of this sensor is non-contact, and there is no need to directly contact the elevator door, so it is safer and more reliable during the opening and closing process of the elevator door. By sensing whether an object is approaching or not through non-contact, the opening and closing operation of the elevator door is controlled to ensure the accurate opening and closing of the elevator door to prevent passengers or objects from being pinched.

[0026] Among them, the real-time status data of the elevator operation is determined based on the elevator operation speed data, the elevator operation load data and the elevator operation door opening and closing data.

[0027] It should be noted that the real-time status data of the elevator operation includes the elevator operation speed data, the elevator operation load data and the elevator operation door opening and closing data.

[0028] A wireless communication module is used to transmit the real-time status data of the elevator operation to the risk management terminal through a wireless network to realize the sharing of the real-time status data of the elevator operation; Specifically, the data acquisition module further includes: A data acquisition frequency adjustment unit, used to extract speed data information during the operation of the elevator, wherein the speed data information includes acceleration, speed change amplitude and speed value; comparing the acceleration with a preset acceleration threshold; When the acceleration exceeds a preset acceleration threshold, the acceleration, speed change amplitude and speed value contained in the speed data information are extracted; Obtaining a speed operation coefficient using the acceleration, speed change amplitude and speed value contained in the speed data information; The speed operation coefficient is obtained by the following formula: ; Among them, R represents the speed operation coefficient; n represents the number of times the speed data information is collected; a i Indicates the acceleration corresponding to the i-th speed data collection; Δv i represents the speed change amplitude corresponding to the speed data information collection for the i-th time; v i represents the speed value corresponding to the i-th speed data collection; t represents the time interval of speed data collection; θ i represents the relative angle between the elevator operation corresponding to the i-th speed data information collection and the preset standard direction; a0 represents the preset acceleration threshold; The speed operation coefficient is compared with a preset first speed operation coefficient threshold and a second speed operation coefficient threshold, and the data collection frequency of the speed data information is adjusted according to the comparison result.

[0029] The technical effect of the above technical solution is: by real-time monitoring of the acceleration during the operation of the elevator and comparing it with the preset acceleration threshold, the solution can quickly respond to significant changes in the operation state of the elevator. Once the acceleration exceeds the threshold, it means that the elevator may be in an abnormal or critical operation state. At this time, comprehensive speed data information (including acceleration, speed change amplitude and speed value) is immediately extracted, which helps to capture the dynamic behavior of the elevator in a timely manner. The solution adopts a conditional trigger data acquisition mechanism, that is, the detail of 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 operation coefficient R, the solution comprehensively considers multiple factors such as acceleration, speed change amplitude, speed value, data acquisition time interval, and the relative angle between the elevator operation direction and the preset standard direction. This multi-dimensional evaluation method helps to more accurately identify potential faults or abnormal behaviors in the operation of the elevator, and provides strong data support for fault warning and diagnosis. According to the comparison results of the speed operation coefficient R with the preset first speed operation coefficient threshold and the second speed operation coefficient threshold, the 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 when the elevator is running abnormally or at critical moments, the data collection frequency can be increased to obtain more detailed data for analysis and diagnosis. This adaptive adjustment mechanism helps to improve the flexibility and response speed of the system. By real-time monitoring and dynamically adjusting the data collection frequency, the solution can promptly detect and respond to abnormal situations in elevator operation, thereby effectively preventing potential safety hazards. This helps to improve the overall stability and safety of the elevator system and protect the lives and property of passengers.

[0030] In summary, this technical solution has achieved significant improvements in performance indicators such as dynamic response capability, data acquisition efficiency, fault warning and diagnosis capabilities, adaptive data acquisition frequency adjustment, and system stability and security.

[0031] Specifically, the speed operation coefficient is compared with a preset first speed operation coefficient threshold and a second speed operation coefficient threshold, and the data collection frequency of the speed data information is adjusted according to the comparison result, including: comparing the speed operation coefficient with a preset first speed operation coefficient threshold and a second speed operation coefficient threshold; When the speed operation coefficient is lower than a preset first speed operation coefficient threshold, the data collection frequency of the speed data information is not adjusted; When the speed operation coefficient is not lower than a preset first speed operation coefficient threshold, but lower than a preset second speed operation coefficient threshold, the first acquisition frequency adjustment coefficient is obtained by using the acceleration, speed change amplitude and speed value included in the speed data information; The first acquisition frequency adjustment coefficient is obtained by the following formula: ; Among them, K 01 represents the first acquisition frequency adjustment coefficient; n represents the number of times the speed data information is collected; a i Indicates the acceleration corresponding to the i-th speed data collection; Δv i represents the speed change amplitude corresponding to the speed data information collection for the i-th time; v i represents the speed value corresponding to the i-th speed data collection; θ i represents the relative angle between the elevator operation corresponding to the i-th speed data information collection and the preset standard direction; a f Indicates the maximum value of acceleration change; Δv b represents the speed change amplitude standard deviation corresponding to the speed data information collection for n times; v b It represents the speed value standard difference corresponding to the speed data information collection for n times; The first acquisition frequency adjustment coefficient is used to obtain the adjusted data acquisition frequency of the speed data information; wherein the adjusted data acquisition frequency of the speed data information is obtained by the following formula: ; Among them, F t Indicates the data collection frequency of the adjusted speed data information; K 01 represents the first acquisition frequency adjustment coefficient; F0 represents the data acquisition frequency of the speed data information before adjustment; When the speed operation coefficient is not lower than a preset second speed operation coefficient threshold, the vibration frequency and vibration amplitude during the operation of the elevator are retrieved, and the data collection frequency of the speed data information is adjusted using the vibration frequency and vibration amplitude.

[0032] The technical effect of the above technical solution is: by comparing the speed operation coefficient with the preset first speed operation coefficient threshold and the second speed operation coefficient threshold, the solution can dynamically adjust the data acquisition frequency according to different operating states. This not only ensures that too much computing resources and storage space will not be wasted when the elevator runs smoothly, but also provides sufficiently detailed data support when the elevator runs abnormally or at critical moments. When the speed operation coefficient is between the first and second speed operation coefficient thresholds, the solution uses multiple parameters such as acceleration, speed change amplitude, speed value, and the relative angle between the elevator operation and the preset standard direction to calculate the first acquisition frequency adjustment coefficient, and adjust the data acquisition frequency accordingly. This multi-parameter comprehensive evaluation method helps to more accurately reflect the real-time operating status of the elevator and improve the accuracy and reliability of data acquisition. When the speed operation coefficient reaches or exceeds the second speed operation coefficient threshold, the solution not only adjusts the data acquisition frequency, but also retrieves additional information such as vibration frequency and vibration amplitude during the elevator operation. This helps to more comprehensively monitor the operating status of the elevator, timely discover potential faults or abnormal behaviors, and take corresponding measures for early warning or intervention, thereby improving fault warning and response speed. This solution avoids unnecessary high-frequency data collection in non-critical states by dynamically adjusting the data collection frequency, thereby saving computing resources and storage space. At the same time, increasing the data collection frequency in critical states to obtain more detailed data also helps to improve the utilization efficiency of system resources. The design of this solution has high flexibility and scalability. By adjusting the preset acceleration threshold, speed operation coefficient threshold, and acquisition frequency adjustment coefficient and other parameters, it can adapt to different models of elevators and different operating environments. In addition, the solution can also add other monitoring parameters or adjust the algorithm according to actual needs to meet more complex monitoring needs.

[0033] In summary, this technical solution has demonstrated significant technical effects in terms of dynamic optimization of data acquisition frequency, improvement of data acquisition accuracy, improvement of fault warning and response speed, efficient use of system resources, and system flexibility and scalability.

[0034] Specifically, when the speed operation coefficient is not lower than the preset second speed operation coefficient threshold, the vibration frequency and vibration amplitude during the operation of the elevator are retrieved, and the data collection frequency of the speed data information is adjusted using the vibration frequency and vibration amplitude, including: When the speed operation coefficient is not lower than a preset second speed operation coefficient threshold, the vibration frequency and vibration amplitude during the operation of the elevator are retrieved; Retrieve the acceleration, speed change range and speed value contained in the speed data information; The second acquisition frequency adjustment coefficient is obtained by using the vibration frequency and vibration amplitude during the operation of the elevator in combination with the acceleration, speed change amplitude and speed value contained in the speed data information; The second acquisition frequency adjustment coefficient is obtained by the following formula: ; Among them, K 02 represents the second acquisition frequency adjustment coefficient; n represents the number of times the speed data information is collected; a i Indicates the acceleration corresponding to the i-th speed data collection; Δv i represents the speed change amplitude corresponding to the speed data information collection for the i-th time; v i represents the speed value corresponding to the i-th speed data collection; θ i represents the relative angle between the elevator operation corresponding to the i-th speed data information collection and the preset standard direction; a0 represents the preset acceleration threshold; f i A represents the vibration frequency corresponding to the i-th speed data collection; i represents the vibration amplitude corresponding to the i-th speed data collection; f c represents the vibration frequency reference value corresponding to the i-th speed data information collection; A0 represents the vibration amplitude reference value corresponding to the i-th speed data information collection; The data collection frequency of the adjusted speed data information is obtained by using the second collection frequency adjustment coefficient; wherein the data collection frequency of the adjusted speed data information is obtained by the following formula: ; Among them, F t Indicates the data collection frequency of the adjusted speed data information; K 02 represents the second acquisition frequency adjustment coefficient; F0 represents the data acquisition frequency of the speed data information before adjustment.

[0035] The technical effect of the above technical solution is: when the speed operation coefficient reaches or exceeds the preset second speed operation coefficient threshold, the solution can automatically retrieve the vibration frequency and vibration amplitude during the operation of the elevator, and dynamically adjust the data acquisition frequency by calculating the second acquisition frequency adjustment coefficient in combination with multiple parameters such as acceleration, speed change amplitude and speed value. This dynamic adjustment mechanism enables the data acquisition frequency to more accurately reflect the actual operation status of the elevator, and improves the pertinence and effectiveness of data acquisition. By introducing vibration frequency and vibration amplitude as reference factors for adjusting the data acquisition frequency, the solution can more comprehensively monitor the operation status of the elevator. Vibration frequency and vibration amplitude are important indicators reflecting the smoothness and safety of elevator operation, which helps to more accurately evaluate the operation status of the elevator, thereby improving the accuracy and reliability of data acquisition. When the elevator operation is abnormal, such as the speed operation coefficient reaches or exceeds the second speed operation 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, so as to take corresponding measures in time for intervention and treatment. This solution avoids unnecessary high-frequency data collection in non-critical states by dynamically adjusting the data collection frequency, thereby saving computing resources and storage space. At the same time, increasing the data collection frequency in critical states to obtain more detailed data also helps to improve the utilization efficiency of system resources. This resource allocation strategy enables the system to reduce resource consumption as much as possible while ensuring the quality of data collection. The design of this solution has high flexibility and scalability. By adjusting the preset acceleration threshold, speed operation coefficient threshold, vibration frequency reference value, vibration amplitude reference value, and acquisition frequency adjustment coefficient, it can adapt to different models of elevators and different operating environments. In addition, the solution can also add other monitoring parameters or adjust the algorithm according to actual needs to meet more complex monitoring needs.

[0036] In summary, the technical solution has shown significant technical effects in terms of dynamic adaptability of data collection frequency, data collection accuracy, fault warning and diagnosis capabilities, efficient use of system resources, and system flexibility and scalability. The improvement of these technical effects helps to more accurately monitor the operating status of elevators, timely discover and deal with potential safety hazards, and thus ensure the safe operation of elevators.
