Description

Technical Field

[0001] The present invention relates to the technical field of elevator safety monitoring, and in particular to an elevator safety monitoring system and method combining video intelligent analysis technology. Background Art

[0002] With the acceleration of urbanization, high-rise buildings have become the norm in urban landscapes. As an indispensable vertical transportation tool in these buildings, the safe operation of elevators is directly related to the life and property safety of passengers. However, the existing elevator safety monitoring systems mostly rely on hardware sensors and simple logical judgments. These systems have obvious limitations in real-time, accuracy and intelligence.

[0003] Traditional monitoring systems usually use contact sensors to detect the operating status of elevators, such as by measuring the speed, acceleration, load and other physical quantities of the elevator to determine whether the elevator is faulty. Although these methods can reflect the operating status of the elevator to a certain extent, they often lack an intuitive understanding of the internal environment of the elevator and are difficult to identify and respond to complex security threats in a timely manner, such as improper behaviors such as electric vehicles entering the elevator and smoking in the elevator. Summary of the invention

[0004] In order to overcome the shortcomings of the existing technology, the present invention provides an elevator safety monitoring system and method based on video intelligent analysis to improve the intelligence level of elevator safety monitoring and reduce the occurrence of elevator failures and accidents.

[0005] The technical solution adopted by the present invention to solve the technical problem is:

[0006] An elevator safety monitoring system based on video intelligent analysis, comprising:

[0007] AI monitoring device, used to analyze video data in the elevator in real time to realize intelligent detection. The detection functions include door opening and closing detection, floor recognition, running direction monitoring, passenger counting, electric vehicle detection, fireworks detection, smoking detection, door blocking, door prying alarm and face liveness recognition;

[0008] A data recording module is used to record the operation data and safety events of the elevator, wherein the operation data includes the number of elevator operations, duration, number of door openings and closings, and number of floors operated;

[0009] The abnormal event alarm module is used to issue an alarm and record the event when a security event is detected.

[0010] Furthermore, the system also includes:

[0011] Remote monitoring and upgrade module, used to remotely view elevator status and perform system upgrades.

[0012] An elevator safety monitoring method based on video intelligent analysis comprises the following steps:

[0013] Step 1: collect audio and video data inside and outside the elevator in real time;

[0014] Step 2: Get data and enter elevator status detection;

[0015] Step 3: record the operation data, including the number of elevator operations, duration, number of door openings and closings, and number of floors operated;

[0016] Step 4, abnormal vibration detection, detects that there is no abnormal vibration and the system is running normally. If there is abnormal vibration, a safety event record is performed; according to the safety event, the corresponding alarm information is output;

[0017] Step 5: trigger different safety responses according to the alarm information, including elevator stopping, sound and light alarm activation, remote upgrade triggering and communication module activation.

[0018] In step 2, the AI ​​monitoring device realizes door opening and closing detection, floor recognition, running direction monitoring, elevator passenger counting, electric vehicle detection, fireworks detection, smoking detection, door blocking, door prying alarm and face liveness recognition.

The application of AI technology enables the system to monitor the internal environment of the elevator in real time through video data, automatically identify and respond to various security threats, thereby improving the intelligence level of monitoring and response efficiency.

[0020] The present invention aims to develop an elevator safety monitoring system and method based on video intelligent analysis in combination with the latest AI technology, so as to overcome the shortcomings of the existing technology and realize comprehensive, accurate and real-time monitoring of the elevator safety status.

[0023] 2. By using AI algorithms to analyze elevator operation data, the system can assess the risk level of elevator operation and take corresponding preventive measures.

[0024] 3. Intelligent analysis can distinguish between real security threats and false alarms, such as distinguishing normal elevator behavior from potential improper behavior, reducing unnecessary intervention.

[0025] 4. The system can monitor the elevator status in real time, including the direction of operation, current floor, number of passengers, etc. Once an abnormality is detected, it will respond immediately to improve the efficiency of handling emergency situations.
