Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0025] see figure 1 As shown in FIG. 1 , it is a schematic flowchart of a control method for elevator safe operation in an embodiment of the present invention. The control method of elevator safe operation in this embodiment comprises the following steps:

[0026] Step S101: Obtain a depth image inside the elevator car, wherein the depth image is obtained from above the interior of the elevator car;

[0027] In this step, the depth image is obtained by shooting downwards from the inside of the elevator car, and the depth image includes information such as image depth v...

Abstract

The invention relates to a control method and system for elevator safety operation. The control method comprises the following steps of: obtaining a depth image inside an elevator car; obtaining a target depth value of an identified object in the depth image when image information of the identified object exists in the depth image; and sending prompting information of leaving an elevator when the target depth value is smaller than a preset depth threshold value. According to the scheme adopted by the invention, the depth image inside the elevator car is identified, analyzed and processed, so that the target depth value of the identified object inside the elevator car can be obtained; when the target depth value is smaller than the preset depth threshold value, the identified object is indicated to be not suitable for taking the elevator, and promoting information of leaving the elevator can be sent to prompt the identified object to leave the elevator, so that occurrence of an injury accident possibly due to the fact that the identified object is not suitable for individually taking the elevator is avoided, and safety of elevator operation is improved.

Description

technical field [0001] The invention relates to the technical field of elevator control, in particular to a control method and system for elevator safe operation. Background technique [0002] The normal operation of the elevator is guaranteed by a series of detection devices, and the failure of any part will ensure that the elevator does not operate normally. [0003] Passengers should pay attention to the actual operation status of the elevator when entering or leaving the car, and enter or leave the car after confirming safety (for example, the elevator has reached the leveling floor and the door is opened normally), so as to avoid dangerous accidents. occur. [0004] At present, during the actual operation of the elevator, if someone who is not suitable for taking the elevator alone enters the elevator, a safety accident may occur. For example, a child enters and exits the car alone, and the child does not have safety awareness. Elevators are prone to injury accidents....
