Embodiment Construction

[0031] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0032] see figure 1 According to a preferred embodiment of the present invention, a method for early warning of the entry of a battery car in an elevator car includes the following steps:

[0033] Step 1. Set that the battery car has been detected in the last frame is false;

[0034] Step 2, obtaining the current video frame image;

[0035] Step 3. Input the current video frame image into the battery car detection model to obtain the attribute information of the target;

[0036] Step 4. Determine whether the battery car is detected, if not, return to step 2, and if so, execute step 5;

[0037] Step 5. Determine whether the battery car has been detected in the previous ...

Abstract

The invention relates to an early warning method for entering of a battery car in an elevator car. The early warning method comprises the following steps that it is set that the battery car monitoredin the last frame is false; a current video frame image is obtained; the current video frame image is inputted into a battery car detection model to obtain attribute information of a target; whether the battery car is detected or not is judged, if not, the step 2 is returned, and if yes, the step 5 is carried out; whether the battery car is detected in the previous frame or not is judged, if so, the step 7 is carried out, and otherwise, the step 6 is carried out; that the battery car monitored in the previous frame is true is set, and the step 2 is carried out; if the battery car enters the elevator car, a warning is reported; and whether to stop detection is judged, if so, detection is stopped, otherwise, the step 1 is carried out. According to the early warning method for entering of thebattery car in the elevator car, multiple targets possibly occurring in the elevator car are detected, two times of judgment are used, and the false alarm rate of targets similar to the battery car such as bicycles is reduced.

Description

technical field [0001] The invention relates to an early warning method, in particular to an early warning method for the entry of a battery car in an elevator car. Background technique [0002] Residential buildings basically use vertical elevators, and the elevator safety accident is closely related to the entry car of the battery car. First, it is easy to cause collisions with the elevator door panels. Second, when the flow of people is large, the passenger capacity is reduced, and the passenger experience is very The third is that charging electric bicycles at home is likely to cause fires and cause even worse effects. Therefore, monitoring the battery car and prohibiting it from entering and warning it to exit is the primary safety behavior identification requirement of the vertical elevator. [0003] The work of the early warning of the battery car in the above-mentioned elevator car mostly still stays in the stage of manual monitoring and warning or artificial real-t...
