The LoRa Data Transmission Terminal is universal communication interactive equipment, which is designed and manufactured based on LoRa RF chip. It integrates two interfaces of industrial standard RS485 and supports a variety of protocols to realize data transmission between wired and wireless devices. It can be widely applied in the IOT, centralized metering and industrial control etc..

The Energy Management System acquires real-time energy consumption data from the acquisition terminal then calculates and stores the data from all sorts (i.e. water, electricity, gas, heating), subareas, sub items and sub time with mathematical method of summarizing and splitting etc. Then checking system, which accurately and quantitatively measures unit energy consumption, can be provided by monitoring and diagnosing the data. Thus energy saving management can be realized.
