Building talk-back devices and network awakening methods therefor

Abstract

The invention discloses network awakening methods for building talk-back devices, enabling the building talk-back device to recover from a sleeping mode to a working mode. The invention also discloses a building talk-back device being capable of recovering from the sleeping mode to the working mode. The network awakening method comprises a first step of defining; a second step of receiving; a third step of determining; and a fourth step of recovering. In the first step, at least one awakening identifier of the device is defined; in the second step, a remote data package is received; in the third step, it is determined whether the remote data package is matched with any one of the awakening identifiers, if yes, awakening interrupt is generated; and in the fourth step, an interrupt signal triggers a processor of the device, so that the processor recovers from the sleeping mode to the working mode. According to the method, innovatively, the building talk-back device can operate with ultralow power consumption; and besides peripheral devices, the processor also can go into a deep sleeping state in a standby state, and can rapidly awaken the network when in use.

Description

technical field [0001] The present invention relates to a network wake-up method for a building intercom device, in particular to a network wake-up method for restoring a building intercom device from a sleep mode to a working mode, and at the same time relates to a method capable of returning from a sleep mode to a working mode Building intercom equipment. Background technique [0002] The building intercom system is a management system that enables visitors, residents and property management centers to communicate with each other, exchange information, and control the safe access passages of the community in multi-storey or high-rise buildings. With the rapid development of Internet technology, the digital building intercom system based on TCP / IP communication protocol is emerging. At the same time, in order to bring better user experience to users, the performance of processors is getting higher and higher. The resulting The problem of power consumption is also becoming ...

AI Technical Summary

Problems solved by technology

However, for a building intercom system, any two devices may communicate with each other, which means that each device needs to know the MAC addresses of all other devices, which brings great difficulty to implementation;

[0009] Secondly, before sending information or making a call to the receiver, the sender must first send a magic packet to wake up the other party because it is not sure whether the other party is on standby, which requires additional steps

And for multicast, the situation is especially bad, the sender must wake up each receiver in turn, which is very cumbersome to implement
