Description

Multifunctional wireless building intercom system Technical Field The utility model relates to the technical field of intercom, in particular to a multifunctional wireless building intercom system. Background Building intercom systems are used for visitor to resident communications, traditional schemes rely on wired wiring or common wireless technology (e.g., wiFi, bluetooth). The existing Mesh network (such as ZigBee) is difficult to support high-definition audio and video transmission due to insufficient bandwidth. And the traditional wired system needs to lay a large number of lines, has high construction cost and is difficult to reform old communities. In addition, common WiFi and Bluetooth coverage areas are small, wall penetrating capacity is weak, and requirements of high-rise buildings cannot be met. Wireless signals are susceptible to architectural structures and electromagnetic interference, resulting in unstable communications. The China patent publication No. CN108924492A discloses an intelligent visual access control intercom system based on a WIFI networking mode, which is matched with an exchanger through a cloud management server without wiring, and solves the problems that the networking structure of the traditional digital visual access control intercom system is based on a wired Ethernet, each unit gate machine mounting point needs to be accessed by a wired network, and the wiring cost is high. However, the cloud management server is adopted, so that the corresponding third party operator is usually required to pay fees, and the third party management is easy to reveal the secret. The Chinese patent publication No. CN205921681U discloses an upgrading framework of an old community building intercom system based on a wireless technology, wherein a unit gate machine is in wired connection with signal conversion equipment, the wireless signal repeater is in wireless connection with the signal conversion equipment, a small wireless local area network is formed among the signal conversion equipment, the wireless signal repeater and an indoor wireless intercom terminal, and a new networking mode is formed by matching the unit gate machine and an indoor machine. In the intercom system, if the unit entrance machine and part of indoor machines are in failure, the wireless calling equipment, the indoor wireless intercom terminals and the wireless signal repeater are all in wireless connection through the WIFI module to form a wireless intercom network, but if the number of the failed indoor machines is large, if the WIFI module is installed for each indoor machine, on one hand, higher hardware cost is required, on the other hand, wiFi signals in the indoor environment are dense (such as a router and intelligent household equipment), and if the extension machine is started, the WiFi can aggravate channel competition, and on the contrary, the communication stability is affected. In addition, conventional WiFi networking typically employs a "star topology," i.e., all devices are connected through a single Access Point (AP), requiring manual replacement of devices and reconfiguration of the network when an extension or repeater fails, with high maintenance costs. Therefore, how to overcome the above-mentioned drawbacks has become an important issue to be solved by the person skilled in the art.
