Therefore, all countries are striving to develop plans to generate electricity in a natural way. Among them, the low-temperature heat generated by the industrial thermal process is considered to have no economic value due to the low temperature, so it is directly discharged by flue gas, low-temperature steam or hot water, resulting in energy waste and heat emission pollution. However, due to the successful development of high-performance thermoelectric conversion equipment (ORC), it can convert thermal energy from 60 ° C to 300 ° C into electricity according to the heat source conditions and the thermal properties of the low boiling working fluid during evaporation and condensation.

The thermoelectric conversion device is provided with a detecting component such as a temperature, a flow, an electric power, a grounding value, and a control unit connected to the detecting component, and the detecting information of the detecting component is collected by the control unit. The information is transmitted to the monitoring center via the Internet for the monitoring center to observe the temperature, flow and power generation of each thermoelectric conversion device, thereby achieving the purpose of remotely monitoring the operation state of each thermoelectric conversion device.
