ZigBee intercom station network system and communication method thereof

Abstract

A ZigBee intercom station network system comprises a plurality of ZigBee intercom station devices which are arranged in a linear mode to form a linear topology ad hoc network. Each ZigBee intercom station device comprises a shell, a power panel and a ZigBee main board, each shell is provided with an outside electric interface, a communication interface and two antennas, the power panels and the ZigBee main boards are arranged inside the shells, the power panels are connected with the outside electric interfaces and the ZigBee main boards, and the ZigBee main boards are connected with the communication interfaces and are provided with two ZigBee receiving and sending modules which are respectively connected with one antenna. The ZigBee intercom station network system is easy to establish, convenient to maintain, strong in redundancy and robustness of the network, and high in bandwidth utilization rate due to the fact that bandwidth loss is distributed to the two ZigBee receiving and sending modules.

Description

technical field [0001] The invention belongs to the field of ZigBee, in particular to a ZigBee intercom base station network system and a communication method thereof. Background technique [0002] Zigbee is a low-power personal area network protocol based on the IEEE802.15.4 standard. The technology specified under this agreement is a short-distance, low-power wireless communication technology. This name comes from the eight-character dance of bees, because bees (bees) use the "dance" of flying and "buzzing" (zig) to shake their wings to communicate with their companions the location information of pollen, that is to say, bees rely on this way Form a communication network in the group. ZigBee is a cheap, low-power short-range wireless networking communication technology. [0003] ZigBee wireless communication technology is mainly used in the field of communication with small data volume, low delay, low energy consumption and large network capacity. The bandwidth is only ...

AI Technical Summary

Problems solved by technology

As the number of base stations increases and the scale of the network increases, the limited bandwidth is occupied by the ad hoc network, resulting in information transmission congestion

Intercom voice information is continuous and uninterrupted real-time data with a large amount of data. Due to the limitation of bandwidth, continuous voice communication cannot be carried out well, and it is difficult to realize continuous voice communication between multiple base stations.
