7. it is suitable for optical signal mark and analytic method as claimed in claim 6, which is characterized in that further include：Database is used
In storage low and high level logical message and corresponding routing indication information；
The low and high level according to the multi-channel electric signal obtains the logical message that each electric signal each represents respectively, including：
By the voltage of the multi-channel electric signal each respectively compared with predetermined reference voltage；
If the voltage of electric signal is greater than the predetermined reference voltage, illustrate for high level, obtain high level logic letter
Breath；
If the voltage of electric signal is less than the predetermined reference voltage, illustrate for low level, to obtain low-level logic information；
The logical message that the basis is drawn obtains signal indication information, including：
Obtained multidigit logical message with the low and high level logical message stored in the database is matched, is obtained opposite
The routing indication information answered is realized and obtains signal routing indication information.
