Multi-mode communication method for monitoring power transmission line state

The present invention relates to a multi-mode communication method for monitoring a power transmission line state, falling within the technical field of electric power communications. In the method, the power transmission line is provided with a perception apparatus for detecting a power transmission line state; power transmission line state signals monitored by the perception apparatus are gathered to a communication terminal and then are sent to a remote monitoring centre by means of the communication terminal; the perception apparatus and the communication terminal are both powered by means of a battery; a main communication network is formed between the perception apparatus and the communication terminal by means of ZigBee networking; a standby communication network is further formed between the perception apparatus and the communication terminal by means of Bluetooth networking; and the communication terminal and the remote monitoring centre are connected by means of WinMAX. By means of the method, the advantage of two short-range wireless communication techniques can be fully used, the limitation of a single technique is broken, the data transmission efficiency is improved, it is guaranteed that the energy of the perception apparatus is reasonably consumed, and the monitoring level regarding a power transmission line state is improved.
