Design of Point to Multi-Point Wireless Communication System Based on ZigBee

To monitor the energy consumption of large public buildings, it is proposed to research a data transmission device on ZigBee-embedded development - TCP / IP is proposed. ZigBee can achieve accurate data and real-time transmission. This paper makes the new data protocol for data transmission and also describes the system focused on realization of hardware and software. The device can realize telecommunication from one dot to multiple slaves and achieve connectivity with the main board through serial ports.
