Description

Technical Field

[0001] This application relates to the technical field of elevator inspection, and more particularly, to an elevator inspection data management system and method. Background Art

[0002] While elevators bring a lot of convenience to people's lives, they inevitably cause many troubles and damages. Especially as the service life of elevators increases, their potential safety hazards become increasingly serious. Various elevator accidents such as overshooting, entrapment, and falling occur from time to time, which not only affects people's daily use but also poses a certain threat to people's lives and safety.

[0003] In the prior art, to reduce the losses caused by accidents caused by elevator failures, elevator maintenance companies adopt preventive maintenance methods to periodically inspect elevator terminals, and the detection means are mostly manual inspections.

[0004] In the related art, elevator inspection data can be uploaded through remote wireless communication. However, if the upload frequency is set too high, problems such as high energy consumption and data redundancy may occur. If the upload frequency is set too low, important data may be missed or the data granularity may be too low to meet the later prediction requirements. Summary of the Invention

[0039] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although some embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as limited to the embodiments set forth herein.

[0041] It should be noted that the concepts such as "first" and "second" mentioned in the present disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order of functions performed by these devices, modules or units or their interdependent relationships.

[0042] It should be noted that the modifications of "one" and "multiple" mentioned in the present disclosure are illustrative rather than restrictive. Those skilled in the art should understand that unless clearly specified otherwise in the context, it should be understood as "one or more".

[0043] The names of the messages or information exchanged between multiple devices in the embodiments of the present disclosure are only for illustrative purposes and are not used to limit the scope of these messages or information.

[0044] The present disclosure will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0045] Refer to Figure 1 As shown, the elevator inspection data management system of the present application includes: a number of elevator terminals and a cloud platform.

[0046] Among them, the elevator terminal is used to collect and upload the elevator inspection data of the elevator. Specifically, the elevator terminal sends the elevator inspection data of the elevator through a wireless communication network.

[0047] More specifically, an elevator generally includes a traction machine, traction steel ropes, and a car. Among them, the traction machine is the power equipment of the elevator, also known as the elevator main machine. Its function is to transmit and deliver power to make the elevator run. It consists of a motor, a brake, a coupling, a speed reducer, a traction wheel, a machine frame, a guide wheel, and an attached handwheel for manual operation of the brake. The guide wheel is generally installed on the machine frame or the bearing beam under the machine frame. The handwheel for manual operation of the brake is either fixed on the motor shaft or usually hung on the nearby wall and then sleeved on the motor shaft when in use. The traction steel ropes are connected between the traction machine and the car to transmit the pulling force to lift or lower the car.

[0048] In order to conduct safety monitoring on the operation of the elevator, relevant parameters of the traction machine, traction steel ropes, and car can be detected. Generally speaking, as Figure 3 shown, vibration sensors and noise sensors can be used to detect the vibration and noise of the traction machine, traction steel ropes, and car. At the same time, a temperature sensor can be used to detect the temperature of the traction machine to find out whether the traction machine is overheated. And the current and speed required for the self-control of the traction machine are also taken as detection items.

[0049] In addition, in order to better monitor the car, one or more gyroscopes can be used to detect the attitude of the car, so as to obtain data that can reflect the attitude of the car.

[0050] As can be seen from the above, these sensors are set at different positions of the entire elevator. As a preferred solution, the elevator terminal of this application includes several Internet of Things communication modules (not shown in the figure), which can conduct short-range communication to summarize the data uploaded by each sensor. As Figure 3 shown, the Internet of Things communication module can select a Smartmesh network module for communication networking, and a Smartmesh network module is set corresponding to the traction machine, traction steel ropes, and car respectively.

[0051] In addition, the elevator terminal is configured with a general remote wireless communication module (not shown in the figure) to summarize the data collected by each Internet of Things communication module again and send it to the cloud platform. As Figure 3 shown, the remote wireless communication module can adopt a 5G module.

[0052] Specifically, the elevator terminal configured for each elevator is equivalent to the "black box" of that elevator.

[0053] As Figure 3 shown, the elevator terminal includes sensors for obtaining the status of key components, a sensor networking module, a 5G communication module, etc. Figure 3The upper-level service applications mainly refer to the cloud platform and other parts on the computer side. The sensors mainly include vibration sensors for monitoring vibration, noise sensors for picking up noise signals, temperature sensors, and attitude sensors composed of three-axis acceleration and three-axis gyroscopes. These sensors need to be independently set at appropriate positions of key components. In addition, the current signal and speed signal are obtained using the current sensor and speed sensor of the traction machine. The above sensors are self-networked to form a local gateway, and the signals are sent to the 5G module. Blocks are formed between the elevator terminals. By building a blockchain and uploading it to the Ethernet via the 5G module, the cloud platform obtains information from the Ethernet and performs interactive processing.

[0054] More specifically, measuring points are arranged at appropriate locations on key components in the elevator, such as the traction machine, traction ropes, and car.

[0055] Various sensors at the elevator terminal are used to collect the vibration signal, noise signal, temperature signal, current signal and speed signal of the traction machine. The characteristic quantities of the vibration, noise and temperature signals are extracted and analyzed to realize health monitoring, fault prediction and emergency rescue. The output torque of the traction machine is calculated according to the current signal, speed signal and relevant parameters of the traction machine, and then the braking torque of the brake is estimated to realize the health monitoring, fault prediction and emergency rescue of the brake. The vibration signal and noise signal of the traction rope are collected and analyzed, and the status of the traction rope and traction wheel is monitored, fault prediction and emergency rescue are carried out. The posture signal of the car and the noise signal outside the car are collected and analyzed, and the status of the car is monitored, fault prediction and emergency rescue are carried out.

[0056] The networking method of sensors in the elevator shaft. The sensors at each measuring point in each elevator are networked through the Smartmesh protocol to form a local gateway. The local gateway is connected to the 5G module and the sensor data is connected to the cloud platform through the 5G network.

[0057] As a specific scheme, the elevator inspection data in this application includes: traction machine vibration data, traction machine noise data, traction machine temperature data, traction machine current data and traction machine speed data, traction wire rope vibration data, traction wire rope noise data, car vibration data, car noise data and car posture data.

[0058] Among them, as a specific solution, the car posture data includes two sets of specific data: X-axis inclination and Y-axis inclination, that is, the inclination angles of the car in two directions on the horizontal plane.

[0059] Among them, Figure 3As shown in the figure, the cloud platform includes: a signal processing module, a fault prediction module, and a maintenance management module. Among them, the signal processing module mainly processes the transmitted sensor signals, extracts and analyzes the characteristic quantities to achieve health monitoring; the fault prediction module mainly focuses on predicting the faults and remaining life of relevant components or equipment based on the analysis and evaluation of big data; the maintenance management module uses the fault prediction results to construct the resource types required for predictive maintenance and on-demand maintenance, including personnel, spare parts, tools, and time, etc., to achieve the closed-loop control of Plan, Do, Check, Act (PDCA).

[0060] The elevator inspection data management method of this application is mainly executed by the above cloud platform.

[0061] Refer to Figure 4 As shown in the figure, the elevator inspection data management method of this application includes the following steps:

[0062] S1: In response to an upload request for elevator inspection data from an elevator terminal, query the upload time in the upload request when the elevator terminal successfully uploaded data last time.

[0063] S2: Send data feedback to the elevator terminal so that the elevator terminal sends the displacement data between the generation time of the current upload request and the upload time in the upload request when the data was successfully uploaded last time.

[0064] S3: Generate an urgency coefficient based on the ratio of the time difference between the generation time of the current upload request of the elevator terminal and the upload time in the upload request when the data was successfully uploaded last time, and the displacement data.

[0065] S4: Determine whether the urgency coefficient is greater than or equal to the urgency threshold. If it is greater, send an upload response to the elevator terminal so that the elevator terminal uploads the elevator inspection data between the generation time of the current upload request of the elevator terminal and the upload time in the upload request when the data was successfully uploaded last time; if not, generate a waiting time based on the urgency coefficient and feedback it to the elevator terminal so that the elevator terminal sends the next upload request after waiting for the waiting time on the basis of the current upload time.

[0066] Through the above steps, the flexible upload of data can be carried out according to the running conditions of the elevator between two upload requests. The data volume of the data in the upload request itself is small and will not affect the system upload. When upload is required, a large amount of data is uploaded.

[0067] As a preferred solution, the above elevator inspection data includes vibration signal data, noise signal data, temperature signal data, current signal data, and / or rotational speed signal data of the traction machine.

[0068] More specifically, the elevator inspection data management method of the present application further includes the following steps:

[0069] S5: In response to an upload request for elevator inspection data from an elevator terminal, determine whether there is an abnormal tag in the upload request; if so, send an upload response to cause the elevator terminal to upload the elevator inspection data between the generation time of the current upload request sent by the elevator terminal and the upload time of the previous successful upload request; if not, query the upload time in the previous successful upload request of the elevator terminal.

[0070] S6: Determine whether there is abnormal data in the elevator inspection data uploaded by the elevator terminal between the generation time of the current upload request sent by the elevator terminal and the upload time of the previous successful upload request; if so, set the waiting time to the minimum waiting time; if not, maintain the waiting time.

[0071] In this way, in case of an emergency such as a suspected fault, the system can still effectively upload the data required for system analysis.

[0072] As a specific solution, step S2 specifically includes:

[0073] S21: Obtain the previous historical displacement data at the upload time in the previous successful upload request.

[0074] S22: Obtain the current historical displacement data at the generation time of the current upload request sent by the elevator terminal.

[0075] S23: Calculate the displacement data based on the difference between the previous historical displacement data and the current historical displacement data.

[0076] As a specific solution, step S3 specifically includes:

[0077] S31: Calculate the time difference between the generation time of the current upload request sent by the elevator terminal and the upload time of the previous successful upload request and obtain the numerical value A of the time difference in seconds;

[0078] S32: Calculate the displacement data and obtain the numerical value B of the displacement data in meters;

[0079] S33: Calculate the emergency coefficient C = B / A.

[0080] As a preferred solution, the average emergency coefficient can also be calculated in a historical cumulative manner, that is, calculate the average value A1 of the numerical value A of the unit acquisition time difference and the average value B1 of the numerical value B of the displacement data respectively, and then make C = B1 / A1. Here, the average value can be the arithmetic mean, variance, etc.

[0081] As a specific solution, step S4 specifically includes: selecting an emergency threshold according to the time difference corresponding to the emergency coefficient. More specifically, the larger the time difference corresponding to the emergency coefficient, the higher the possible risk level. In this case, a smaller emergency threshold needs to be selected, so that in addition to the usage frequency of the crossbeam elevator terminal from the ratio perspective, the time factor is also comprehensively considered.

[0082] As a preferred solution, the upload requests and elevator inspection data of the elevator terminal in this application are transmitted through a mobile communication network. Exactly because of the use of a mobile communication network and the network architecture of the mobile communication network itself, if the elevator inspection data is uploaded at a high fixed frequency all the time, it will occupy the communication bandwidth and the efficiency is low. While using a lower frequency, the required elevator inspection data cannot be obtained in time when an abnormality occurs. However, adopting the above solution can effectively make the elevator terminal upload data more efficiently according to the specific situation.

[0083] By adopting the above solution, the upload data frequency can be dynamically adjusted according to the actual situation of data fluctuations, thereby reducing the energy consumption of the elevator terminal and also reducing the capacity requirement of data storage on the cloud platform.

[0084] As Figure 5 shown, the cloud platform in the elevator inspection data management system of this application may further include: a query module, configured to query the upload time in the upload request when the elevator terminal successfully uploaded data last time in response to an upload request for uploading elevator inspection data of an elevator terminal; a feedback module, configured to send data feedback to the elevator terminal so that the elevator terminal sends the displacement data between the generation time of the current upload request and the upload time in the upload request when the elevator terminal successfully uploaded data last time; a generation module, configured to generate an emergency coefficient according to the ratio of the time difference between the generation time of the current upload request of the elevator terminal and the upload time in the upload request when the elevator terminal successfully uploaded data last time and the displacement data; a judgment module, configured to judge whether the emergency coefficient is greater than or equal to the emergency threshold. If it is greater, an upload response is sent to the elevator terminal so that the elevator terminal uploads the elevator inspection data between the generation time of the current upload request of the elevator terminal and the upload time in the upload request when the elevator terminal successfully uploaded data last time. If not, a waiting time is generated according to the emergency coefficient and fed back to the elevator terminal so that the elevator terminal sends the next upload request after waiting for the waiting time based on the current upload time.
