The invention relates to the technical field of elevator intelligent control, and discloses an intelligent elevator control method under a mixed scene condition, which comprises the following steps of: acquiring an image of a passenger in an elevator, extracting features from the image by adopting a target detection algorithm based on a receptive field, and optimizing feature information so as to detect a character target in the image; performing accurate face recognition on the detected character target; voice instructions of elevator users are obtained, and the voice instructions of the users are subjected to signal separation through an improved blind source separation algorithm; voiceprint extraction is carried out on the separated elevator user voice instruction to judge whether the elevator user voice instruction is a legal user or not, and floor information which the legal user wants to reach is extracted; and the extracted floor information is added to elevator dispatching control for cooperative processing. According to the method, whether the passengers in the elevator are legal or not is judged, the mixed voice instruction signals in the mixed scene in the elevator are separated, and voice instructions of different users in the elevator are obtained.

    本发明涉及电梯智能控制的技术领域,公开了一种混合场景条件下的智能电梯控制方法,包括:获取电梯内部乘客图像,采用基于感受野的目标检测算法从图像中提取特征,并对特征信息进行优化,从而检测图像中的人物目标;对检测到的人物目标进行精准人脸识别;获取电梯用户的语音指令,利用改进的盲源分离算法将用户的语音指令进行信号分离;对分离后的电梯用户语音指令进行声纹提取判断是否为合法用户,提取合法用户想要达到的楼层信息;将提取到的楼层信息添加到电梯调度控制中进行协同处理。本发明所述方法实现电梯内乘客是否合法用户的判断,并实现对电梯内混合场景下混合语音指令信号进行分离处理,得到电梯内不同用户的语音指令。
