Energy management and control system based on ZigBee network and realizing method thereof

Abstract

The invention discloses an energy management and control system based on a ZigBee network. The system comprises a field layer, a communication network layer and a management layer. The network communication layer uses a ZigBee communication protocol. The invention further discloses a realizing method of the energy management and control system based on the ZigBee network. The realizing method is characterized in that energy planning management, energy performance management, energy quality management, energy analysis and forecast management and energy operation support management modules are comprised. According to the invention, the efficiency of management and production scheduling command of an energy enterprise can be improved.

Description

Technical field [0001] The present invention involves an energy data collection system, especially the energy control system based on the ZigBee network. Background technique [0002] The current energy data collection methods are RS485 bus, GPRS, WIFI, etc.The RS485 bus has the advantages of good anti -noise interference, long transmission distance, multi -stop, data customization, etc. It is widely used. At present, the smart instrument on the market basically supports the RS485 protocol.GPRS has wireless long -distance communication capabilities and real -time nature, large system capacity, large data transmission volume, and network transmission rates can theoretically reach 171.2kbit / s.WiFi, as a wireless transmission method, has the advantages of no need to wiring and large data transmission. [0003] The above three methods of deficiencies: Product manufacturers using the RS48 bus interface are respectively, and the data format is not uniform. Users need to be re -programm...

AI Technical Summary

Problems solved by technology

[0003] The shortcomings of the above three methods: the manufacturers of products using the RS48 bus interface are fragmented, the data format is not uniform, and the user needs to reprogram; the 900 MHz (1800 MHz) working frequency band used by the GPRS network needs to be authorized, and the construction, maintenance, and operation of the entire network need to be authorized. Both require the support of local GPRS network operators, the total cost of the network is high, and the working area is strictly limited to the coverage of the local GPRS network, the flexibility is poor, and the expansion is inconvenient; the single-point coverage distance of WiFi technology is too short, and there is no sleep mode , high power consumption, short continuous working time in the case of independent battery power supply
