Embodiment 1

[0040] A fault automatic identification method for an elevator hall door provided in this embodiment includes the following steps:

[0041] S1: Construct an elevator hall door fault detection model based on a machine learning algorithm; the input of the elevator hall door fault detection model is the characteristic data of the motion state of the elevator hall door in one opening and closing cycle. The input of the hall door fault detection model is the velocity, angular velocity and acceleration of the three axes of the elevator door. The output of the elevator hall door fault detection model is the judgment result of the current elevator hall door fault type.

[0042] S2: Collect the motion state data of the elevator hall door in the normal state and various fault types, and the motion state data is the input required by the elevator hall door fault detection model in the training or identification phase. In this embodiment, the relevant characteristic data is also drawn in...

Embodiment 2

[0060] This embodiment provides a fault monitoring system for an elevator hall door. The fault monitoring system adopts the automatic identification method for elevator hall door faults as in Embodiment 1 to identify the motion state of the hall door in each floor elevator, so as to realize the detection of various types of faults. timely monitoring. like Figure 5 As shown, the fault monitoring system includes: a hall door sensor, a signal transmission module, a data relay processor, a communication module, and a cloud server. The topology of the system is as Image 6 shown.

[0061] Wherein, the hall door sensor includes an inertial measurement unit and a displacement measurement unit. The inertial measurement unit includes three single-axis acceleration sensors and three single-axis gyroscopes; the inertial measurement unit is used to measure independent three-axis velocity signals, acceleration signals and angular velocity signals. The displacement measuring unit inclu...

Embodiment 3

[0072] This embodiment provides a fault monitoring system for elevator hall doors. The difference between the fault monitoring system provided by this embodiment and Embodiment 2 is that: Figure 7 As shown, the system in this implementation also includes a local data server and a local application server; all data received and generated in the cloud server are stored in the local data server; the local application server is used to respond to the request of the manager and provide Provides access to all data in the local data server.

[0073] Specifically, in this embodiment, the manager opens a browser in the local application server to access the server with a fixed domain name, or enters a password in the software to log in to the corresponding account, obtains the data in the local data server, and controls the movement of the hall doors of each elevator. Status to browse. On the local application server side, the real-time motion status of all elevators is displayed in ...

Abstract

The invention relates to the field of nondestructive testing, and particularly relates to an automatic fault identification method for an elevator landing door. The automatic fault identification method for the elevator landing door comprises the following steps: S1, constructing an elevator landing door fault detection model based on a machine learning algorithm; S2, acquiring motion state data of the elevator landing door, and drawing a corresponding motion state curve; and S3, taking feature data corresponding to the marked motion state curve and data of a fault type as a model training data set, namely a training set; S4, training the elevator landing door fault detection model through the training set, and verifying a training effect of the model by using a testing set; and S5, obtaining the feature data of the landing door motion state of a corresponding elevator floor when a landing door opening and closing instruction is received every time, identifying through the elevator landing door fault detection model, and reserving a corresponding real-time motion state curve and a corresponding identification result thereof. According to the invention, the problems of poor monitoring effect, low efficiency, and insufficient real-time performance due to the fact that existing elevator landing door state monitoring depends on manual work, are solved.

Description

technical field [0001] The invention relates to the field of non-destructive testing, in particular to an automatic fault identification method for elevator hall doors. Background technique [0002] The elevator hall door is one of the most important parts of the elevator, and it is also the most frequently used part in the working environment and the most vulnerable to external impact or extrusion. The national standard GB-7588 "Safety Code for Manufacture and Installation of Elevators" puts forward design and installation requirements for the safety performance of hall doors alone. However, according to incomplete statistics, about 70% of the personal casualties in elevators are caused by elevator hall doors, so hall doors play an extremely important role in protecting the safety of personnel and the normal operation of elevators. [0003] In daily use, the hall door often fails due to various reasons such as foreign objects on the threshold, lack of emergency guide devic...
