Problems solved by technology

[0005] The purpose of the present invention is to provide a transmission line multi-source data fusion device with load priority control and its control method to solve the problem that the existing devices proposed in the background technology are independent of each other, resulting in a large number of devices on the tower and poor interoperability strong, and there are problems such as high cost and poor adaptability. At the same time, because the device is placed on the pole tower, the power supply method is mostly solar energy and battery power supply, especially in extreme weather conditions. The continuous working time lacks optimization, which makes the device performance limited short board problem
