This patent relates to a multi-mode communication method for detecting states of power transmission line, which belongs to electric power communication technology field. In this method, there are sensing devices installed on power transmission line. These sensing devices are used to detect status signals of power transmission line. Status signals are sent to remote monitoring center through communication terminals. Both sensing devices and communication terminals are powered by battery. The main communication network between sensing devices and communication terminals is formed by ZigBee network. Meanwhile, Bluetooth network is a backup communication network between sensing devices and communication terminals. Communication terminals and remote monitoring center are linked through WinMAX. This method can take full advantage of these two short-range wireless communication technologies and break limitations of a single technology, ensure reasonable energy consumption, improve efficiency and quality of data transmission.
