The invention relates to a double-channel multifunctional electric energy information collector and a communication method thereof. The double-channel multifunctional electric energy information collector comprises an RS485 channel meter reading module, an MCU module, a power carrier module, a wireless module and a memory, wherein the RS485 channel meter reading module is connected with the MCU module; the wireless module having the functions of wireless information transmission and wireless information reception and the power carrier module are both connected with the MCU module; the RS485 channel meter reading module collects data and respectively collects, processes and stores signals output by an electric energy meter or electricity utilization data signals; the electricity utilization information collected by the RS485 channel meter reading module is exchanged with the MCU module; the MCU module, the power carrier module and the wireless module form double channels; and the powercarrier module and the wireless module are set as a main channel and a standby channel. The MCU module firstly selects the main channel to communicate with other collectors; when the main channel cannot be used for communication successfully, data transmission is carried out with other collectors through the standby channel; and when the main channel recovers communication, the main channel is used for communication again.
