Problems solved by technology

[0003] However, existing methods still have deficiencies, for example, when the elevator is equipped with larger but lighter objects, or carries multiple people but has not yet reached the overload standard due to the light weight, although the space in the elevator at this time It is already full, but due to its light weight, the elevator control system will not judge that the elevator is full or overloaded, and the elevator will still respond to the external control of the elevator and continue to stop at floors where it does not need to stop, thus reducing the operating efficiency of the elevator. Increase the consumption of the elevator, but also increase the cost of elevator operation

Embodiment 1

[0026] Step 1, as shown in Figure 1, before the elevator starts to run, that is, when the elevator is unloaded, the elevator control system first takes an image of an empty elevator through the video monitoring device in the elevator, that is, the monitoring camera, and stores it in the image processor. As the reference empty elevator image for comparison, it is best to shoot the reference empty elevator image in the environment where the elevator is running normally; , it is necessary to re-shoot the stored reference air elevator image;

[0027] Step 2. When the elevator is running, for example, when the elevator is loaded with relatively large but light weight objects such as boxes or furniture, the elevator control system obtains real-time images in the elevator from the video monitoring device in the elevator and transmits them to the image processing device;

[0028] Step 3: The image processor compares the real-time image in the elevator with the reference empty elevato...

Embodiment 2

[0033] As shown in Figure 2, a kind of function elevator control system that uses video monitoring device, comprises video monitoring device i.e. camera, elevator control system, it is characterized in that: also be provided with image processor in this system, image processor is connected with camera and camera respectively The elevator control system is connected;

[0034] In practical application, the reference empty elevator image taken by the camera in the elevator, that is, the image taken by the camera when the elevator is unloaded, is stored in the image processor in advance, and the image processor used in this implementation is an image processor comprising an embedded CPU; When the elevator is running, the camera transmits the acquired real-time image signal to the image processor, and then the image processor compares the stored reference empty elevator image with the real-time image from the camera, because the reference empty elevator image and the real-time image...

Abstract

The present invention belongs to the technical field of intelligent control system and relates to a function elevator control method and a system with a video monitoring device. The existing elevator control system usually relies on weight information to determine whether the elevator is full, when the elevator is filled with an object with large size and light weight, even if the elevator space is filled fully, the elevator control system cannot determine the elevator is full because of light weight and continues to stop on unnecessary floor so that elevator operation efficiency is reduced and elevator operation cost is increased. The system provided by the present invention can gain real-time image with the video monitoring device and compare the real-time image with empty elevator image shot previously so that when the system finds out that most part of the image is different from the empty elevator image, the elevator can be determined to be full. With load and space service condition of the elevator, the present invention can control the elevator more efficiently and improve operation efficiency of the elevator.

Description

technical field [0001] The invention belongs to the technical field of intelligent control systems, and in particular relates to a method and system for controlling a functional elevator using a video monitoring device. Background technique [0002] Existing elevator control systems usually rely on weight information to judge whether the elevator is full. When the load in the elevator exceeds the preset weight value of the elevator control system, that is, overload, it sends a full load signal to the elevator control system, and then the elevator control system makes the elevator Closed, no longer respond to the external control of the elevator, only respond to the internal control of the elevator, so that the elevator can reduce unnecessary floor stops and improve the operating efficiency of the elevator. [0003] However, existing methods still have deficiencies, for example, when the elevator is equipped with larger but lighter objects, or carries multiple people but has ...
