In the specification, the same or similar reference numerals denote the same or similar components. The following description of the embodiments of the present invention with reference to the accompanying drawings is intended to explain the general inventive concept of the present invention and should not be construed as limiting the invention.
Furthermore, in the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the disclosure. It may be evident, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are shown in schematic form in order to simplify the drawing.
According to a general technical concept of the present invention, there is provided an elevator abnormal state reporting system, including: the vibration button is arranged on a control panel in the elevator car; the noise button is arranged on a control panel in the elevator car; the elevator controller is in communication connection with a control panel in the elevator car; and the server is in communication connection with the elevator controller. When the vibration button or the noise button is pressed down, the control panel sends a vibration abnormal command or a noise abnormal command to the elevator controller; the elevator controller is suitable for uploading the received vibration abnormal instruction or noise abnormal instruction and the time when the vibration button or the noise button is pressed to the server.
Fig. 1 shows a schematic view of a control panel in an elevator car according to an exemplary embodiment of the invention; fig. 2 shows a schematic diagram of an elevator abnormal state reporting system according to an exemplary embodiment of the present invention.
As shown in fig. 1 and 2, in the illustrated embodiment, the system for reporting an abnormal state of an elevator mainly includes: a vibration button 11, a noise button 12, an elevator controller 100, and a server 200. A vibration button 11 and a noise button 12 are provided on a control panel 10 inside the elevator car. Other function buttons for operating the elevator, for example floor buttons, are also provided on the control panel 10. The elevator controller 100 is in communication with a control panel 10 within the elevator car, e.g., wired or wireless communication connection. The server 200 is in communication connection with the elevator controller 100, e.g. wired or wireless communication connection.
As shown in fig. 1 and 2, in the illustrated embodiment, when the vibration button 11 or the noise button 12 is pressed, the control panel 10 transmits a vibration abnormality command or a noise abnormality command to the elevator controller 100.
As shown in fig. 1 and 2, in the illustrated embodiment, the elevator controller 100 is adapted to upload the received vibration abnormality command or noise abnormality command and the time (including date, hour, minute, second) when the vibration button 11 or noise button 11 is pressed to the server 200.
As shown in fig. 1 and 2, in the illustrated embodiment, when a passenger in an elevator car feels a vibration abnormality or a noise abnormality, the passenger may report the vibration abnormality or the noise abnormality of the elevator car by pressing a vibration button 11 or a noise button 12. In this way, more and more accurate abnormal state sample data can be provided for predictive maintenance of the elevator.
As shown in fig. 1 and fig. 2, in the illustrated embodiment, the elevator abnormal state reporting system further includes: a vibration sensor 1 and a noise sensor 1. The vibration sensor 1 is provided on the elevator car to detect a vibration parameter (e.g., amplitude, frequency, etc. of vibration) of the elevator car and transmit the detected vibration parameter to the elevator controller 100. The noise sensor 1 is provided on the elevator car, and detects a noise parameter (e.g., amplitude, frequency, etc. of noise) of the elevator car and transmits the detected noise parameter to the elevator controller 100.
As shown in fig. 1 and 2, in the illustrated embodiment, the elevator controller 100 includes an error notification prevention device adapted to determine whether a vibration parameter or a noise parameter detected when the vibration button 11 or the noise button 11 is pressed is abnormal.
As shown in fig. 1 and 2, in the illustrated embodiment, if the false alarm prevention device determines that the vibration parameter or the noise parameter detected when the vibration button 11 or the noise button 11 is pressed is normal, the elevator controller 100 determines that the vibration button 11 or the noise button 11 is pressed by mistake (for example, a child presses the button maliciously or an adult touches the button unintentionally), and does not upload the vibration abnormality instruction or the noise abnormality instruction currently received and the time corresponding to the instruction currently received to the server 200. This avoids reporting abnormal data samples of the elevator by mistake.
As shown in fig. 1 and 2, in the illustrated embodiment, if the anti-false alarm device determines that the vibration parameter or the noise parameter detected when the vibration button 11 or the noise button 11 is pressed is abnormal, the elevator controller 100 uploads the currently received vibration abnormal command or noise abnormal command and the time corresponding to the currently received command to the server 200.
As shown in fig. 1 and 2, in the illustrated embodiment, if the false alarm prevention device determines that the vibration parameter or the noise parameter detected when the vibration button 11 or the noise button 11 is pressed is abnormal, the elevator controller 100 also uploads the currently detected vibration parameter or noise parameter to the server 200.
As shown in fig. 1 and 2, in the illustrated embodiment, if the currently detected vibration parameter or noise parameter exceeds the predetermined vibration parameter range or the predetermined noise parameter range, the false alarm preventing device determines that the currently detected vibration parameter or noise parameter is abnormal. If the currently detected vibration parameter or noise parameter is within the preset vibration parameter range or the preset noise parameter range, the false alarm preventing device judges that the currently detected vibration parameter or noise parameter is normal.
As shown in fig. 1 and 2, in the illustrated embodiment, the server 200 is a remote cloud server remote from the elevator, and the elevator controller 100 wirelessly communicates with the remote cloud server.
However, the invention is not limited to this, for example, in another exemplary embodiment of the invention, the server 200 may also be a computer provided in the elevator machine room, and the elevator controller 100 may be in wired communication with the computer.
