Elevators are one of the necessary equipment for high-rise buildings, and with technological progress and safety requirements, elevators are no longer just pure lifting equipment. Various monitoring and electronic equipment will also be set up. Allow managers to monitor the status of the elevator at any time. However, the current elevator equipment mostly uses analog architecture design, but the analog elevator system still has many shortcomings. For example, the monitor in the elevator cannot provide high-resolution images, and it is difficult for the monitoring personnel to identify the situation in the elevator, especially the public security. It is impossible to accurately grasp the internal condition of the elevator during an event or emergency. Second, the walkie-talkie system in the elevator is only connected to the walkie-talkie in the management room, and there must be a manager in the management room to be able to play a role. Third, the analog elevator system is a closed control system, and its operation status and the health status of mechanical and electrical equipment cannot be connected and integrated with the building's own DCS weak current monitoring system.

Therefore, the system host 120 is also connected to the monitoring terminal communication device 121 and the monitoring terminal operating device 122. The digital packets received by the system host 120 can be restored to audio by the monitoring terminal communication device 121 and played, or received by the monitoring terminal communication device 121, and transmitted to the cabin terminal communication device 112 in the same way, so that the monitoring terminal personnel You can talk to the passengers in the car in real time. The monitoring terminal operating 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, and the digital packets will be restored into images, and the elevator digital information and images will be displayed. In other words, the personnel on the monitoring terminal can browse the images and digital information of the elevator through the monitoring terminal operating device 122, and can monitor the conditions in the car 10 and the operating conditions 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 the elevator digital information. The database 130 will continue to store elevator digital information, which can be further used for data analysis, and data such as elevator life and estimated maintenance time can be calculated. 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 images from the system host 120 via the Internet 40. That is to say, in one embodiment, the manager can monitor the status of the elevator and internal images and sounds through a smart phone or a tablet computer (remote device 140). In addition, the remote device 140 can also input audio, and transmit the audio to the system host 120 through the Internet 40, and then transmit the audio to the cabin-side communication device 112 in the cabin 10 via the digital information capturer 110 and the coaxial cable 20, by The car-side communication device 112 plays audio. In other words. The manager can communicate with passengers in the carriage 10 through a smart phone or a tablet computer. In an embodiment, the system host 120 is also suitable for connecting to an external access control system or security system and other building management systems. That is, the elevator walkie-talkie system 100 of the present invention can also be connected to an external building management system, so that the security unit can monitor and manage the area more effectively. The elevator intercom system 100 of the present invention can be directly installed in a conventional elevator system. The car-side modulation and demodulation module 111, the car-side communication device 112, the camera lens 113 and the control-side modulation and demodulation module are installed in the car 10 114. The audio and images obtained by the car-side communication device 112 and the camera lens 113 are converted into digital packets, which are then converted into radio frequency signals by the car-side modulation and demodulation module 111, and the existing coaxial cable 20 of the elevator system can be used to transmit the radio frequency. Signal, the audio and video are sent to the control panel 30. Then, the control terminal modulation and demodulation module 114 disposed around the control panel 30 receives the radio frequency signal, and converts the radio frequency signal back to a digital packet. The digital packets are then sent to the system host 120 and sent to the monitoring terminal communication device 121 to be converted back to audio, and the monitoring terminal operating device 122 restores the digital packets to images. In this way, the manager can watch the images in the car 10 through the monitoring terminal communication device 121 and the monitoring terminal operating device 122 or talk with passengers in the car 10. Further, the system host 120 uses the Internet 40 to transmit audio and video to the remote device 140, so that the manager can use the mobile device to monitor the condition in the elevator. On the other hand, if the digital information extractor 110 is installed on the existing control panel 30 of the elevator system, the digital information extractor 110 can convert the control command of the control panel 30 into elevator digital information, so that the elevator digital information can be transmitted to The system host 120 and the monitoring terminal operating device 122 can receive and display the digital information of the elevator, so that the management personnel can monitor the operation status of the elevator system. Further elevator digital information can also be transmitted to the remote device 140 via the Internet 40, so that the management personnel can use the mobile device to monitor the operation status of the elevator. The elevator intercom system 100 of the present invention does not need to greatly modify the traditional elevator system, and can easily install the elevator intercom system 100 to the traditional elevator system, greatly reducing the installation cost of the elevator intercom system 100. In addition, the coaxial cable 20 of the elevator system is used to transmit data in a radio frequency manner, which can avoid interference caused by elevator operation and maintain stable data transmission.
