Description

Technical Field

[0001] The present invention relates to the technical field of elevators, and in particular to an elevator system based on a mobile terminal and an elevator abnormality assessment method. Background Art

[0002] At present, many elevators are equipped with remote monitoring systems. With the help of the remote monitoring system, information such as elevator operation data can be transmitted to the remote monitoring center. The remote monitoring center analyzes and processes these elevator data to realize various functions including predictive maintenance and fault diagnosis. For example, the remote monitoring center uses the elevator drive control data, such as the acceleration of the car from the moving speed data of the car. According to the acceleration, the vibration of the elevator car during movement can be further judged, and when the vibration exceeds the standard, the elevator is considered abnormal. However, when simply using the elevator operation data to realize functions such as judging whether the elevator is abnormal, a certain error rate may occur. Of course, according to the functions to be realized, adding corresponding sensors can solve the error problem when realizing functions based on remote monitoring data, but it will lead to increased costs and complex system structure.

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

[0004] The technical problem to be solved by the present invention is to reduce errors in implementing functions based on remote monitoring data without increasing costs and structural complexity.

[0005] In order to solve the above technical problems, the present invention discloses an elevator system based on a mobile terminal, comprising:

[0006] The first judgment module: used to judge whether the elevator is abnormal;

[0014] Preferably, when there is a specific time period or a specific displacement within the elevator journey, the judgment unit determines that the recurrence 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 recurrence condition is met; the specific displacement refers to a time period whose distance is not less than a distance threshold and within which the recurrence 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 length of the elevator journey, or when the ratio of the specific displacement to the length of the elevator journey is less than a threshold, determining the start time and end time or the start position and end position when the recurrence condition is met.

[0016] Preferably, the control module controls the mobile terminal sensor to detect elevator abnormalities only during the period between the start time and the end time, or during the period between the start position and the end position.

[0029] The present invention can reduce errors when implementing functions based on remote monitoring data without increasing costs and structural complexity. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Figure 1 This is a schematic diagram of an elevator system based on a mobile terminal in Example 1. DETAILED DESCRIPTION

[0031] The present invention will be further described in detail below in conjunction with 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] The first judgment module: used to judge whether the elevator is abnormal;

[0035] The second judgment module: when the first judgment module determines that the elevator is abnormal, it judges whether the abnormality meets the first condition, the first condition including: condition 1, it can be reproduced when the recurrence condition is met; condition 2, it can be detected by the sensor in the mobile terminal;

[0036] The first receiving module is used to receive the elevator call signal registered by the passenger using the mobile terminal;

[0037] The third judgment module: when the second judgment module determines that the abnormality satisfies the first condition, judging whether the recurrence condition is satisfied during the elevator trip of the passenger corresponding to the elevator call signal;

[0038] Control module: when the third judgment module determines that the recurrence condition is satisfied during the elevator trip of the passenger corresponding to the elevator call signal, control the application pre-installed in the mobile terminal to enable the sensor in the mobile terminal to implement the detection of elevator abnormality;

[0039] The second receiving module is used to receive the detection result of the sensor in the mobile terminal;

[0040] Processing module: processes the detection results and evaluates the abnormality of the elevator according to the processing results.

[0041] The abnormalities here include one or more of the following: excessive elevator speed tracking error, excessive acceleration change, excessive noise in the car, excessive vibration in the car, low 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 judges whether an abnormality occurs in the elevator according to one or more of the elevator operation information, the elevator control information or the elevator detection information.

[0043] The second judgment module analyzes the properties of the abnormality, determines the conditions for the occurrence of the abnormality in the elevator according to the properties of the abnormality and uses it as the recurrence condition, and determines whether the abnormality can be detected by the sensor in the mobile terminal according to the properties of the abnormality and the sensor configured by the mobile terminal. It can be seen that the recurrence condition is determined by the properties of the abnormality.

[0044] Typically, the factors involved in the reproduction conditions include: elevator car position, elevator running direction, elevator running speed / acceleration, load in the car, etc.

[0045] Here is a specific application example:

[0046] Assume that the first judgment module finds through analysis based on the remote monitoring data that each time the elevator car goes up to a place between the 5th and 6th floors, the actual speed of the elevator cannot track the speed command well, that is, the speed tracking error is large, and the amplitude and frequency of the actual speed change are relatively large. For this abnormal phenomenon, the second judgment module can determine that the recurrence condition is that the elevator car goes up to the 5th and 6th floors 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 must be large, which can be detected by the acceleration sensor of the mobile terminal). In this way, when the first receiving module receives the elevator call signal of the 1st floor and the destination floor is the 10th floor, the third judgment module determines that one of the recurrence conditions is met, and the control module can control the elevator call software pre-installed in the passenger's mobile phone, and use the software to call the acceleration sensor of the mobile phone for detection, so that the second receiving module obtains the acceleration data of the car when it goes up and passes through the 5th and 6th floors. By processing the acceleration data, the processing module can determine the actual vibration of the elevator car in this interval, thereby providing a more reliable basis for the specific evaluation of the abnormality.

[0047] Example 2

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

[0049] The third judgment module further includes:

[0050] A determination unit: used for determining an elevator trip corresponding to the elevator call signal according to the elevator call signal;

[0051] Prediction unit: used to predict the operation status of the elevator during the elevator journey;

[0052] A judgment unit: judging whether the recurrence condition is satisfied during the elevator journey according to the operation status of the elevator during the elevator journey.

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

[0054] Example 3

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

[0056] The third judgment module further includes:

[0057] A determination unit: used for determining an elevator trip corresponding to the elevator call signal according to the elevator call signal;

[0058] Prediction unit: used to predict the operation status of the elevator during the elevator journey;

[0059] A judging unit: judging whether the recurrence condition is satisfied during the elevator journey according to the operation status of the elevator during the elevator journey;

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

[0061] Example 4

[0062] This embodiment further illustrates the control module based on the third embodiment.

[0063] The control module controls the mobile terminal sensor so that it detects elevator abnormalities only during the period between the start time and the end time, or during the period between the start position and the end position.

[0064] Example 5

[0065] This embodiment provides further supplementary explanation based on any of the above embodiments.

[0066] The control device controls the application pre-installed in the mobile terminal so that it requests the passenger to enable the sensor in the mobile terminal before enabling the sensor in the mobile terminal, and only enables the sensor in the mobile terminal to detect elevator abnormalities after obtaining the passenger's authorization.

[0067] Example 6

[0068] This embodiment provides the working process of the elevator system based on the mobile terminal of the above embodiment. That is, this embodiment provides an elevator abnormality assessment method based on the mobile terminal, including the following steps:

[0069] Step 1: Determine the anomaly to be evaluated;

[0070] Step 2: Analyze the properties of the anomaly to be evaluated, and determine whether the anomaly to be evaluated can be reproduced and the reproduction conditions based on the properties;

[0071] Step 3: Determine whether the abnormality to be evaluated can be detected by the mobile terminal sensor;

[0072] Step 4: Determine whether the recurrence condition during the elevator trip is met according to the elevator call signal. If so, proceed to step 5; otherwise, end;

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

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

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

[0076] When the ratio of the specific time period to the total time length 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 time and end time or the start position and end position when the recurrence condition is met.

[0077] The step 5 controls the mobile terminal sensor so that it detects elevator abnormalities only during the start time and the end time, or during the start position and the end position.

Without departing from the principles of the present invention, those skilled in the art may also make many variations and improvements, which should also be regarded as the protection scope of the present invention.
