Abstract

The invention discloses a building intercom system based on a high-speed wireless network. The system comprises an entrance machine used for calling a client terminal according to a user instruction and controlling the locking and unlocking of an electric lock, an SIP server which is in network connection with the entrance machine and used for network calling and communication between the entrance machine and the client terminal, and the client terminal used for communication between a resident and the entrance machine. A visitor visits through the entrance machine, the entrance machine sends calling information to the SIP server, the SIP server inquires whether APP software is installed on the client terminal and whether the APP software is connected to the network and feeds an inquiry result back to the entrance machine, the entrance machine is connected to the client terminal through the network if the APP software is online, the entrance machine is connected to the client terminal through a telephone network if the APP software is not online, the resident confirms the identity of the visitor through the client terminal and then sends opening information to the entrance machine, and the entrance machine controls the locking and unlocking of the electric lock according to the opening information. The system does not need a special network and is convenient and fast to install, convenient to use and low in assembling and maintaining cost.

Description

technical field [0001] The invention relates to an intercom system, in particular to a building intercom system based on a high-speed wireless network. Background technique [0002] Due to the needs of security and intelligent management, building intercom products have developed rapidly after entering China. With the development of broadband network technology, many manufacturers have launched a video intercom system based on broadband network. But present various forms of intercom systems all have the following problems: [0003] (1) First of all, the construction investment is relatively large, and the owner not only has to bear the cost of the outdoor station and the indoor station, but also [0004] Bear the construction costs of the network. Moreover, when laying the network, it is inevitable to drill the wall and drill the floor. [0005] Operation, especially for some old residential quarters brings a lot of inconvenience. [0006] (2) Some products have begun t...

Problems solved by technology

[0005] operation, especially for some old residential quarters, it brings a lot of inconvenience

[0006] (2) Some products have begun to use the operator's ready-made network (including wired and wireless methods) to realize visual intercom, but it is still necessary to install a home terminal for each resident, the overall cost is still high, and the communication protocol on the network Inevitably contains the content of its own manufacturer, so it is difficult to unify the interchangeability of products

[0007] (3) In the current intercom system, the indoor unit is installed in a fixed position in the owner's room. When there is no one in the owner's home or when a visitor comes, the intercom cannot open the door.
