Tunnel is usually implemented in underground, and impenetrably face radio communication base station establishes communication environment, it is therefore necessary to be tunnel
Road introduces dedicated communication system.In addition, wireless signal is decayed in tunnel, more open place is rapider, and signal relay station is also
The emphasis of communication environment construction.Currently, constructing the wireless communications environment of crusing robot in tunnel, it is necessary to just be built every 100m
One has the radio communication relay station of antenna, this not only greatly improves the project amount of tunnel crusing robot and is constructed into
This, considers, each relay station necessarily has independent current source, introduces relay station too much from secure context, certainly will be in tunnel
Operational safety work cause bigger burden.Therefore, using 6 communication modes of leaky wave cable, communication is reliable, avoids tunnel longer
When need the drawbacks of arranging several relay points.
