In this embodiment, the method for controlling an elevator according to a control command includes: the control arrives at the floor which needs to arrive first, and then the control elevator arrives at the final arriving floor.

Specifically, a user holds a mobile phone A, sends control voice and information through the mobile phone A, identifies an elevator nearest to the user according to geographical position information in the information sent by the mobile phone A, judges whether the user has authority to perform voice control on the elevator according to an ICCID code and/or an IMEI mobile phone identification code, directly feeds back an authority failing instruction to the mobile phone when the authority fails, de-noises the control voice when the authority passes, converts text information according to the de-noised control voice, screens and extracts digital information from the text information, judges a floor which the user wants to reach as 14 when the extracted digital information is directly identified as 14, judges that the floor where the mobile phone is located is 4 according to the information sent by the user, namely the floor where the user is located currently is 4, and the floor where the elevator is located is 1, firstly controls the elevator to reach 4 floors, after the user gets on the elevator, controlling the elevator to reach the 14 th floor, so that the user can reach the floor which the user wants to reach;

when the control voice is removed, the digital information cannot be identified, and the signal abnormity is directly fed back to the mobile phone;

when three numbers are identified, wherein the numbers are respectively 1, 3 and 4, the elevator can only reach 40 floors at the highest, if a user wants to go to a floor with the single digit, the user only needs to input 1 number, the floor with the single digit is removed in the judgment, the final arriving floor of the elevator is preliminarily judged to be 13 or 34, when the user is at the floor 1 at present, the user can be judged that the user possibly wants to go to the floor 13 or 34, if the current elevator is at the floor 5, the elevator is controlled to the floor 1 at first, and after the user gets on the elevator, the elevator is controlled to arrive at the floor 13 or 34 in sequence; when the user is at the 20 th floor, the final arriving floor of the elevator is 13 or 34, and is above the user and below the user, which is contrary to the general situation of taking the elevator (only going up or down when taking the elevator once), therefore, the noise reduction control voice is judged to be invalid, the elevator control command is not generated, and the signal abnormal command is fed back to the mobile phone.
