[0005] 2. Patent document CN214879334U discloses an elevator safety monitoring device, "comprising an elevator car, the upper left end inside the elevator car is fixedly connected with a camera device, and the four sides of the top of the elevator car are fixedly connected with millimeter-wave displacement and deformation devices. The right side of the upper end of the elevator car is fixedly connected with a car environment detection device; The traction steel belt is fixedly connected, and the other end of the traction steel belt is fixedly connected with the traction sheave. Firstly, the real-time data of the elevator detection devices such as the camera device, the magnetic flux leakage detection device, and the millimeter wave displacement and deformation device can be transmitted through the signal processor. Collected and analyzed, it solves the problems of the current elevator detection equipment, such as bulky volume, long detection interval, and insufficient real-time performance. The elevator is overweight
"The device lacks a structure to protect the detection structure, and the monitoring structure is easily damaged by external influences.

Embodiment 1

[0063] An IoT intelligent elevator safety monitoring system, comprising:

[0064] Car: It is used to set alarms and security surveillance cameras inside, and collect car alarm information and surveillance video in real time;

[0065] Video processing module: used to capture the abnormal behavior in the monitoring video, and determine whether there is an abnormal event;

[0066] Alarm processing module: used to perform event matching on the alarm information, and obtain the processing strategy of the alarm event.

[0067] The invention is an elevator safety detection system based on the Internet of Things, which is attached figure 1 It is the structure of the elevator car 1 of the present invention. The main monitoring method of the present invention is based on two methods: the alarm device 4 and the safety monitoring camera. This is similar to the physical structure of the safety detection device in the prior art, but this The invention is very different from the prior art ...

Embodiment 2

[0069] The video processing module includes:

[0070]Data analysis unit: used to analyze and process the surveillance video, and determine element features in the surveillance video; wherein

[0071] The element features include: event features, event composition features, event-independent features, and scene features;

[0072] Event generation unit: build an event model according to the event characteristics by the following formula:

[0073]

[0074] Among them, T ij Represents the jth event feature of the i-th event; L represents the dimension of the event feature; C j Represents the element feature of the jth event; K j Represents the composition feature of the jth event; Y represents the scene feature; F j Represents the event feature irrelevant to the jth event; i∈n, i is a positive integer, n represents the total number of types of events that may occur; j∈m, j is a positive integer, m represents the total number of events that may occur;

[0075] In the video ...

Embodiment 3

[0081] The alarm processing module includes:

[0082] Alarm collection unit: used to receive the alarm signal of the alarm device, and determine the corresponding alarm event in the monitoring video through the alarm signal;

[0083] Alarm analysis unit: according to the alarm event, determine the event parameter of the alarm event under the DS argument;

[0084] Content matching system: according to the event parameters, alarm event matching is performed to determine the specific alarm event content;

[0085] Operation and maintenance processing unit: According to the content of the event, the event is divided into grids, the compensation processing strategy of each event grid is determined, the compensation processing strategy is combined, and the processing method for solving the alarm event is generated.

[0086] After the alarm signal is sent out in the present invention, because the present invention is a method for orienting the occurrence of abnormal events, the alarm...

Abstract

The intelligent elevator safety monitoring system based on the Internet of Things comprises a lift car, a partition plate is installed on the inner wall of the inner side of the lift car, two sets of installation bases are installed at the bottom of the partition plate, safety monitoring cameras are installed at the bottoms of the installation bases, an alarm is installed at the bottom of the partition plate, and the alarm is located between the two sets of installation bases; a blower is installed at the top of the partition plate, a controller is installed at the top of the partition plate and located on one side of the blower, and a tension sensor is installed on the outer wall of the top of the lift car. According to the elevator, the oxygen density sensor is installed, the oxygen density in the elevator car is monitored through the oxygen density sensor, then detected information is transmitted to the controller through the transmission line, and the controller judges whether oxygen is sufficient or not.

Description

technical field [0001] The invention relates to the technical field of Internet of Things intelligent safety, in particular to an Internet of Things intelligent elevator safety monitoring system. Background technique [0002] Elevator refers to a permanent transportation device that serves several specific floors in a building, and its car runs on at least two rows of rigid tracks perpendicular to the horizontal plane or with an inclination angle of less than 15° to the plumb line. The vertical elevator, its internal car is used to carry people or things, and transport people or things to the designated floor. [0003] The defects of the Internet of Things intelligent elevator safety monitoring system in the prior art are: [0004] 1. The patent document CN207511625U discloses an elevator safety monitoring device, "including an external sensor module and a data control module. The external sensor module includes a leveling monitoring module installed on the top of the eleva...
