The invention relates to an intercom system and a door machine thereof. The door machine comprises an audio transmission device, an MCU, a call device, multiple channel switching devices and multiple power supply detection devices; the call device, the audio transmission device, the multiple channel switching devices and the multiple power supply detection devices are separately connected with the MCU, the call device and the audio transmission device are separately connected with a sound bus of the door machine, the sound bus of the door machine is separately connected with the multiple channel switching devices, the channel switching devices are correspondingly connected with the sound buses of extension sets of the intercom system, and the power supply detection devices are correspondingly connected with the sound buses of the extension sets of the intercom system. By adoption of the intercom system and the door machine thereof, the system wiring can be reduced, and no intermediate equipment is required, therefore the cost is low.
Description
technical field [0001] The invention relates to the technical field of video intercom, in particular to an intercom system and an outdoor station. Background technique [0002] The intercom system is a set of modern residential service measures. It provides two-way communication between visitors and residents, achieves voice recognition to improve safety and reliability, saves a lot of time and improves work efficiency. [0003] In the traditional multi-family building intercom system, one door station is connected to the extensions of each household respectively. In order to isolate the sound lines of the extensions of each household and prevent the signals of different households from interfering with each other, generally through multi-line system and adding intermediate equipment To realize the connection from the door station to each extension, the intercom system needs at least power wires, ground wires, video wires, audio wires and call wires, and the implementation c...
