■Solving issues： Solve the collection requirements of environmental information scattered in the factory area, inverter cross-building data, factory machine energy consumption and utilization rate data.

■Solutions： Wireless transmission via LoRa

■Methods：

1.Various sensors、 inverters and electricity meters scattered in the factory, the response data is transmitted to the server through LoRa

2.Solve the problems that the sensor data collection site cannot be wired in the factory and flexible construction requirements.

3.Save time and cost of construction

4.Wiring, and install quickly
