The invention provides an elevator remote talkback system which comprises an elevator five-party talkback device and a voice communication device. The elevator remote talkback system further comprises a signal switching device. The signal switching device comprises a differential signal interface, a signal processing unit and a five-party talkback signal interface. The differential signal interface is used for being connected with the voice communication device. The five-party talkback signal interface is used for being connected with the five-party talkback device, and the signal processing unit is used for converting signals from the five-party talkback signal interface into differential signals, transmitting the differential signals to the differential signal interface, converting the signals from the differential signal interface into five-party talkback device signals and transmitting the signals to the five-party talkback signal interface. An access device of the elevator remote talkback system is further provided. By means of mutual conversion of the differential signals and the five-party talkback device signals, interaction between the voice communication device and the five-party talkback device is achieved, and an elevator five party talkback system can be flexibly expanded.
Description
technical field [0001] The invention relates to the field of elevator intercom, and more specifically, relates to an elevator remote intercom system and an access device. Background technique [0002] With the rapid development of my country's social economy and the improvement of people's living standards, elevators have been widely used as a means of transportation in buildings. The elevator five-party intercom system is also called the elevator five-party intercom system. The call between the five parties of the bottom pit extension. The elevator five-party intercom system has the characteristics of fast installation, simple operation, quick response, and clear sound quality, so it is widely used in community property, elevator monitoring, elevator intercom and other occasions. [0003] However, the above-mentioned elevator five-party intercom system calls are limited to five parties, that is, the management center host, car extension, machine room extension, car top ex...
