Power transmission line dynamic capacity increase temperature monitoring system and method

The invention provides a power transmission line dynamic capacity increase temperature monitoring system and method. A temperature collecting device detects the temperature of a power transmission line, generates temperature data and sends the temperature data to a data processing device. The data processing device conducts coding on the temperature data, generates communication messages and transmits the communication messages in different wireless transmission modes through a first communication device and a second communication device. According to the power transmission line dynamic capacity increase temperature monitoring system and method, the communication messages are transmitted in the two wireless transmission modes with different transmission distances and used for power transmission line dynamic capacity increase analysis, and therefore the influence of environmental factors on data transmission is reduced. Compared with a traditional power transmission line dynamic capacity increase temperature monitoring system, the stability of data transmission is improved.
