Description

Elevator intercom system

A walkie-talkie system, especially an elevator walkie-talkie system.

Elevator is one of the necessary equipment for high-rise buildings, and with the advancement of technology and safety requirements, elevator is no longer just a simple lifting equipment. Various monitoring and electronic equipment will also be set up. It allows managers to monitor the state of the elevator at any time. However, the current elevator equipment mostly uses analog architecture design, but the analog elevator system still has many defects. For example, the monitors in the elevator are mostly unable to provide high-resolution images, and it is difficult for the monitoring personnel to recognize the conditions in the elevator, especially the public security. In the event of an emergency, it is impossible to accurately grasp the internal conditions of the elevator. Second, the intercom system in the elevator is only connected to the intercom in the management room, and there must be managers in the management room to play a role. Third, the analog elevator system is a closed control system. Its current operating status and the health status of mechanical and electrical equipment cannot be integrated with the DCS weak current monitoring system of the building itself. In summary, there are still many defects in the analog monitoring equipment in elevators at present. How to overcome these defects is worth considering by those with ordinary knowledge in the field.

The car-end modulation and demodulation module 111 is adapted to receive digital packets from the car-end communication device 112 and the camera lens 113 and convert the digital packets into a radio frequency signal. In this embodiment, the car-end modulation and demodulation module 111 converts digital packets into radio frequency signals through COFDM modulation technology. In this way, it can be transmitted through the traditional coaxial cable 20 without additional transmission lines. Furthermore, the transmission of the radio frequency signal by the coaxial cable 20 has better anti-interference performance, which can avoid the interference of the audio and the image, thereby maintaining the quality of the audio and the image. The digital information extractor 110 is connected to the control panel 30. The digital information extractor 110 is adapted to capture multiple pieces of elevator digital information from the control panel 30. In other words, the digital information extractor 110 reads the control commands of the control panel 30 from the control panel 30, such as ascending, descending, opening the door, stopping the floor, and delaying the opening of the door, and converts these control commands into digital messages. In order to transmit these data through the network interface (such as Modbus/TCP communication protocol). The control-end modulation and demodulation module 114 is disposed around the control panel 30 and is connected to the car-end modulation and demodulation module 111, the digital information extractor 110, and the system host 120.

Therefore, the system host 120 is also connected to the monitor-side calling device 121 and the monitor-side operating device 122. The digital packets received by the system host 120 can be restored to audio by the monitor-side talking device 121 and played, or the audio can be received through the monitor-side talking device 121 and sent to the car-side talking device 112 in the same way to allow the monitor-side personnel Instantly talk with passengers on the side of the car. The monitoring device 122 is a device with a screen and an operating interface, such as a computer. The monitoring terminal operating device 122 can receive digital packets and elevator digital information from the system host 120. The digital packets will be restored to images and display the elevator digital information and images. That is to say, the personnel at the monitoring end can browse these images and the digital information of the elevator through the operating device 122 at the monitoring end, and can monitor the status in the car 10 and the operating status of the elevator system. In addition, the system host 120 can also be connected to a database 130 and a remote device 140 via the Internet 40. The database 130 can obtain elevator digital information from the system host 120 via the Internet 40 and store these elevator digital information. The database 130 will continuously store the elevator digital information, and further use the elevator digital information for data analysis, and calculate the elevator life and estimated maintenance time and other data. The remote device 140 is, for example, a mobile device such as a smart phone or a tablet computer. In addition, the remote device 140 can obtain elevator digital information, audio, or video from the system host 120 through the Internet 40. That is to say, in one embodiment, the manager can monitor the status of the elevator and the internal images and sound through a smartphone or a tablet computer (remote device 140). In addition, the remote device 140 can also input audio, and send the audio to the system host 120 through the Internet 40, and then send it to the car-side communication device 112 in the car 10 through the digital information extractor 110 and the coaxial cable 20, by The car-side communication device 112 plays audio. In other words. The manager can communicate with the passengers in the cabin 10 through a smartphone or a tablet computer. In one embodiment, the system host 120 is further adapted to be connected to an external building management system such as an access control system or security system. That is, the elevator intercom system 100 of the present invention can also be connected to an external building management system, so that the security unit can more effectively monitor and manage the area.
