Description

Technical Field

[0001] This invention relates to the field of elevator technology, and more specifically to an elevator system and an elevator anomaly assessment method based on a mobile terminal. Background Technology

[0002] Currently, many elevators are equipped with remote monitoring systems. These systems transmit elevator operation data to a remote monitoring center, which analyzes and processes this data to perform various functions, including predictive maintenance and fault diagnosis. For example, the remote monitoring center can use elevator drive control data, such as the car's acceleration from its speed data, to further determine the elevator car's vibration during movement and identify any abnormalities when the vibration exceeds acceptable levels. However, relying solely on elevator operation data to determine whether an elevator is malfunctioning can lead to a certain error rate. While adding appropriate sensors can address the error issues associated with remote monitoring data, this increases costs and complicates the system structure.

[0003] Therefore, how to reduce errors when implementing functions based on remote monitoring data without increasing costs and structural complexity has become an important technical problem. Summary of the Invention

[0004] The technical problem to be solved by this invention is to reduce errors when implementing functions based on remote monitoring data without increasing cost and structural complexity.

[0005] To address the aforementioned technical problems, this invention discloses an elevator system based on a mobile terminal, comprising:

[0006] First judgment module: used to determine whether the elevator is malfunctioning;

[0007] Second judgment module: When the first judgment module determines that the elevator is abnormal, it determines whether the abnormality meets the first condition. The first condition includes: condition 1, it can be reproduced when the reproduction condition is met; condition 2, it can be detected by the sensor in the mobile terminal.

[0008] First receiving module: used to receive elevator call signals registered by passengers using mobile terminals;

[0009] The third judgment module: When the second judgment module determines that the anomaly meets the first condition, it determines whether the reproduction condition is met during the elevator travel period of the passenger corresponding to the elevator call signal;

[0010] Control module: When the third judgment module determines that the reproduction condition is met during the elevator travel period of the passenger corresponding to the elevator call signal, it controls the application pre-installed in the mobile terminal to enable the sensor in the mobile terminal to detect elevator abnormalities.

[0011] Second receiving module: used to receive the detection results of the sensors in the mobile terminal;

[0012] Processing module: Processes the detection results and evaluates the abnormality of the elevator based on the processing results.

[0013] Preferably, the third judgment module further includes: a determination unit for determining the elevator travel distance corresponding to the elevator call signal; a prediction unit for predicting the elevator's operating status during the elevator travel distance; and a judgment unit for judging whether the reproduction condition is met during the elevator travel distance based on the elevator's operating status during the elevator travel distance.

[0014] Preferably, when a specific time period or a specific displacement exists within the elevator travel distance, the judgment unit determines that the reproduction condition is met; the specific time period refers to a time period whose duration is not less than a time threshold and within which the reproduction condition is met; the specific displacement refers to a time period whose distance is not less than a distance threshold and within which the reproduction condition is met.

[0015] Preferably, the third judgment module further includes: a decision unit: when the ratio of the specific time period to the total time of the elevator travel, or when the ratio of the specific displacement to the length of the elevator travel is less than a threshold, the start time and end time or the start position and end position of the reproduction condition are determined.

[0016] Preferably, the control module controls the mobile terminal sensor to perform elevator anomaly detection only during the start and end times, or during the start and end positions.

[0017] Preferably, the control device controls an application pre-installed in the mobile terminal to request permission from the passenger to enable the sensors in the mobile terminal before enabling the sensors in the mobile terminal, and only enables the sensors in the mobile terminal to detect elevator anomalies after obtaining the passenger's authorization.

[0018] This invention also provides a method for elevator anomaly assessment based on a mobile terminal, comprising:

[0019] Step 1: Identify the anomalies to be evaluated;

[0020] Step 2: Analyze the attributes of the anomaly to be evaluated, and determine whether the anomaly to be evaluated is reproducible and the conditions for reproducibility based on the attributes;

[0021] Step 3: Determine whether the anomaly to be evaluated can be detected by the mobile terminal's sensors;

[0022] Step 4: Determine whether the conditions for recurrence during the elevator journey are met based on the elevator call signal. If they are met, proceed to Step 5; otherwise, end the process.

[0023] Step 5: After the elevator journey begins, control the mobile terminal sensor to perform detection;

[0024] Step 6: Receive and process the detection data, and evaluate the anomalies to be evaluated based on the processing results.

[0025] Preferably, step 4 determines a specific time period or a specific displacement that exists during the elevator travel, and when a specific time period or a specific displacement exists during the elevator travel, it is determined that the reproduction condition is met; the specific time period refers to a time period whose duration is not less than a time threshold and within which the reproduction condition is met; the specific displacement refers to a time period whose distance is not less than a distance threshold and within which the reproduction condition is met.

[0028] Beneficial technical effects

[0029] This invention can reduce errors when implementing functions based on remote monitoring data without increasing costs or structural complexity. Attached Figure Description

[0030] Figure 1 This is a schematic diagram of an elevator system based on a mobile terminal, as shown in Example 1. Detailed Implementation

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0032] Example 1

[0033] like Figure 1 As shown, this embodiment provides an elevator system based on a mobile terminal, characterized in that it includes:

[0034] First judgment module: used to determine whether the elevator is malfunctioning;

[0035] Second judgment module: When the first judgment module determines that the elevator is abnormal, it determines whether the abnormality meets the first condition. The first condition includes: condition 1, it can be reproduced when the reproduction condition is met; condition 2, it can be detected by the sensor in the mobile terminal.

[0036] First receiving module: used to receive elevator call signals registered by passengers using mobile terminals;

[0037] The third judgment module: When the second judgment module determines that the anomaly meets the first condition, it determines whether the reproduction condition is met during the elevator travel period of the passenger corresponding to the elevator call signal;

[0038] Control module: When the third judgment module determines that the reproduction condition is met during the elevator travel period of the passenger corresponding to the elevator call signal, it controls the application pre-installed in the mobile terminal to enable the sensor in the mobile terminal to detect elevator abnormalities.

[0039] Second receiving module: used to receive the detection results of the sensors in the mobile terminal;

[0040] Processing module: Processes the detection results and evaluates the abnormality of the elevator based on the processing results.

[0041] The abnormalities mentioned here include one or more of the following: excessive elevator speed tracking error, excessive acceleration variation, excessive noise in the car, excessive vibration in the car, insufficient illumination in the car, abnormal registration button function (unable to register or cancel), and abnormal display of the display device.

[0042] The first judgment module determines whether the elevator is malfunctioning based on one or more of the elevator operation information, elevator control information, or elevator detection information.

[0043] The second judgment module analyzes the attributes of the anomaly, determines the conditions under which the anomaly occurs based on these attributes, and uses these conditions as the conditions for reproduction. It then determines whether the anomaly can be detected by the sensors configured on the mobile terminal, based on the anomaly attributes and the specific sensors configured on the mobile terminal. Therefore, the reproduction conditions depend on the attributes of the anomaly.

[0044] Typically, the elements involved in reproducing the conditions include: elevator car position, elevator direction of travel, elevator speed / acceleration, and load inside the car.

[0045] Below is a specific application example:

[0046] Suppose that the first judgment module, through analysis of remote monitoring data, discovers that each time the elevator car ascends to a certain point between the 5th and 6th floors, the actual speed of the elevator cannot accurately track the speed command, i.e., the speed tracking error is large, and the amplitude and frequency of the actual speed changes are relatively large. For this anomaly, the second judgment module can determine that the reproduction condition is that the elevator car ascends to the 5th or 6th floor and can be detected by the mobile terminal sensor (when the amplitude and frequency of the actual speed change of the car are large, the vibration of the car will inevitably be large, which can be detected by the acceleration sensor of the mobile terminal). Thus, when the first receiving module receives an elevator call signal for the 1st floor and the destination floor is the 10th floor, the third judgment module determines that one segment of the reproduction condition is met. The control module can then control the elevator call software pre-installed on the passenger's mobile phone, using this software to call the phone's acceleration sensor for detection. The second receiving module then obtains the acceleration data of the car during its ascent and passage through the 5th and 6th floors. The processing module, by processing the acceleration data, can determine the actual vibration of the elevator car in this range, thus providing a more reliable basis for specifically assessing the anomaly.

[0047] Example 2

[0048] This embodiment further explains the third judgment module based on embodiment 1.

[0049] The third judgment module further includes:

[0050] Determining unit: used to determine the elevator travel distance corresponding to the elevator call signal based on the elevator call signal;

[0051] Prediction unit: used to predict the elevator's operating status during the elevator journey;

[0052] Judgment Unit: Determines whether the reproduction condition is met during the elevator travel period based on the elevator's operating status.

[0053] When a specific time period or a specific displacement exists within the elevator travel distance, the judgment unit determines that the reproduction condition is met; the specific time period refers to a time period whose duration is not less than a time threshold and within which the reproduction condition is met; the specific displacement refers to a time period whose distance is not less than a distance threshold and within which the reproduction condition is met.

[0054] Example 3

[0055] This embodiment further explains the third judgment module based on embodiment 1.

[0056] The third judgment module further includes:

[0057] Determining unit: used to determine the elevator travel distance corresponding to the elevator call signal based on the elevator call signal;

[0058] Prediction unit: used to predict the elevator's operating status during the elevator journey;

[0059] Judgment Unit: Determines whether the reproduction condition is met during the elevator travel period based on the elevator's operating status during the elevator travel period;

[0060] Decision unit: When the ratio of the specific time period to the total time of the elevator journey, or when the ratio of the specific displacement to the length of the elevator journey is less than a threshold, the start time and end time or start position and end position of the reproduction condition are determined.

[0061] Example 4

[0062] This embodiment further explains the control module based on embodiment 3.

[0063] The control module controls the mobile terminal sensor to perform elevator anomaly detection only during the start and end times, or during the start and end positions.

[0064] Example 5

[0065] This embodiment provides further supplementary explanations based on any of the foregoing embodiments.

[0066] The control device controls an application pre-installed on the mobile terminal, which requests permission from the passenger to enable the sensors on the mobile terminal before activating them. The sensors on the mobile terminal are only activated to detect elevator malfunctions after the passenger's authorization is obtained.

[0067] Example 6

[0068] This embodiment illustrates the operation of the elevator system based on a mobile terminal as described in the previous embodiments. Specifically, this embodiment provides a mobile terminal-based elevator anomaly assessment method, including the following steps:

[0069] Step 1: Identify the anomalies to be evaluated;

[0070] Step 2: Analyze the attributes of the anomaly to be evaluated, and determine whether the anomaly to be evaluated is reproducible and the conditions for reproducibility based on the attributes;

[0071] Step 3: Determine whether the anomaly to be evaluated can be detected by the mobile terminal's sensors;

[0072] Step 4: Determine whether the conditions for recurrence during the elevator journey are met based on the elevator call signal. If they are met, proceed to Step 5; otherwise, end the process.

[0073] Step 5: After the elevator journey begins, control the mobile terminal sensor to perform detection;

[0074] Step 6: Receive and process the detection data, and evaluate the anomalies to be evaluated based on the processing results.

[0075] Preferably, step 4 determines a specific time period or a specific displacement that exists during the elevator travel, and when a specific time period or a specific displacement exists during the elevator travel, it is determined that the reproduction condition is met; the specific time period refers to a time period whose duration is not less than a time threshold and within which the reproduction condition is met; the specific displacement refers to a time period whose distance is not less than a distance threshold and within which the reproduction condition is met.

[0076] When the ratio of the specific time period to the total time of the elevator journey, or when the ratio of the specific displacement to the length of the elevator journey, is less than a threshold, step 4 determines the start and end times or the start and end positions for the reproduction conditions to be met.

[0077] Step 5 controls the mobile terminal sensor to perform elevator anomaly detection only during the start and end times, or during the start and end positions.

[0078] The present invention has been described in detail above through specific embodiments and examples, but these are not intended to limit the invention. Many modifications and improvements can be made by those skilled in the art without departing from the principles of the invention, and these should also be considered within the scope of protection of the present invention.
