Problems solved by technology

[0002] The current intercom methods are mainly wired intercom and wireless intercom. The wired intercom has the limitations of pre-embedded lines and fixed locations, and it is difficult to apply in renovated buildings.
Although there is no installation problem for wireless intercom, the interference from the wireless environment is a difficult problem to solve. At present, most intercoms have multi-channel options, but it is impossible to switch all intercom devices at the same time. to the same free channel, but also have a certain degree of privacy

Embodiment Construction

[0014] See figure 1 As shown, a hybrid indoor intercom device includes a gateway 1 , at least a first intercom terminal 2 and a second intercom terminal 3 . The hybrid indoor intercom device uses power lines as the transmission carrier of intercom channel control instructions, uses radio frequency as the transmission carrier of audio intercom signals, and uses multi-channel frequency hopping switching to realize independent occupation of idle frequencies; the gateway 1 The first intercom terminal 2 and the second intercom terminal 3 are electrically connected and communicated through the power line.

[0015] The first intercom terminal 2 and the second intercom terminal 3 can be a calling terminal and a called terminal each other, and the calling terminal is responsible for wireless interception and automatic switching of wireless idle channels and intercom control, and through the power line Send the idle channel and intercom control information to gateway 1, and the gateway...

Abstract

The invention discloses a hybrid indoor intercom device. The device comprises a gateway, at least one first intercom terminal and a second intercom terminal. According to the hybrid indoor intercom device, a power line is taken as a transmission carrier for an intercom channel control instruction; wireless radio frequency is taken the transmission carrier for an audio intercom signal; independent occupation of idle frequency can be realized through adoption of a multi-channel frequency hopping mode; and connection with a local area network or wide area network is realized through the gateway. The outstanding feature of the device is that channel control and signal transmission are separated from carriers, therefore, the simple, reliable and private indoor intercom can be realized under wireless interference, the installation of the device is not limited, and the intercom can be realized after the device is connected with the power line at any location.

Description

technical field [0001] The invention relates to the fields of civil communication and smart home, in particular to a hybrid indoor intercom device. Background technique [0002] The current intercom methods are mainly wired intercom and wireless intercom. The wired intercom has the limitations of pre-embedded lines and fixed locations, and it is difficult to apply in renovated buildings. Although there is no installation problem for wireless intercom, the interference from the wireless environment is a difficult problem to solve. At present, most intercoms have multi-channel options, but it is impossible to switch all intercom devices at the same time. To the same idle channel, but also have a certain degree of privacy. Contents of the invention [0003] The purpose of the present invention is to separate channel control and signal transmission on the carrier to ensure simple, reliable and private indoor intercom under the premise of wireless interference, and it is not l...
