Further, demodulated by the electric signal being processed into, using the information after demodulation as the access information for accessing the router 100, when accessing the router 100, the processor 102 specifically for：

The electric signal being processed into is demodulated into the form of binary number；And the obtained corresponding information of binary number will be demodulated as the access information for accessing the router 100, access the router 100.

Alternatively, when the electric signal being processed into be demodulated into the form of binary number, the processor 102 specifically can with but be not limited only in the following manner：

The first implementation：

Identifying processing into electric signal in each low level, the high level after each low level and each low level is demodulated respectively：If it is high level to extend again after low level after the first preset duration threshold value, high level after low level and low level is demodulated into binary number 1, if it is low level to extend again after low level after the first preset duration threshold value, the high level after the low level and the low level is demodulated into binary number 0.

Second of implementation：

Identifying processing into electric signal in each low level, the high level after each low level and each low level is demodulated respectively：If it is high level to extend again after low level after the first preset duration threshold value, high level after low level and low level is demodulated into binary number 0, if it is low level to extend again after low level after the first preset duration threshold value, the high level after the low level and the low level is demodulated into binary number 1.

The third implementation：

Identifying processing into electric signal in each high level, the low level after each high level and each high level is demodulated respectively：If it is high level to extend again after high level after the second preset duration threshold value, low level after high level and high level is demodulated into binary number 1, if it is low level to extend again after high level after the second preset duration threshold value, the low level after the high level and the high level is demodulated into binary number 0.
