Position:In channel set among passageway, channel all-around can accuse chromatic camera. Spot video image uses multichannel chance of end of video answer consumed and cable transmit video image and control information to control center, the real time that realizes monitoring image on wall of control center TV shows. Controlling a center to be able to realize long-range remote control to chromatic camera, control includes to be opposite all-around cloud stage and alterable lens first class, the attendant that makes control a center can monitor in real time the traffic situation inside channel, auxiliary attendant directs drive a vehicle. When producing the situation of a disaster, the calamity that understands the scene in time and passenger are scattered circumstance.
(5) urgent phone system
Channel sets urgent telephone call, offer to cry for help directly for the driver the special communication system that recourse, to accident of fire, traffic, use hot line means, direct computer lead plane, hand-in-hand travel is acousto-optic call the police, with 110, 120 linkage.

The system can broadcast all sorts of traffic information to wait to driver of car of the contact inside channel; The announcement of emergency undertakes when producing emergency, in the meantime, when getting fire alarm signal, can enter fire automatically urgent broadcast condition, call the police automatically with fire the system achieves linkage.
(7) channel is ventilated control subsystem
Ventilated control subsystem is main wait for composition by detector of wind direction of detector of controller of fan PLC controller, the area inside channel, CO/VI, wind speed. According to the ventilated means of channel, it is respectively among Sui hole, CO/VI detector and detector of wind speed wind direction are installed near entrance and ventilated shaft, according to CO/VI and detector of wind speed wind direction detect parameter. Use to fan of the efflux inside the hole " PLC fan controller controller of → PLC area → monitoring center " 3 class control.
When highway tunnel produces fire, start an axis in time to shed fan, make sure the lowermost wind speed inside channel is not gotten under 2.5m/s, make aerosol rapid to same way eduction, ensure car is orderly and scattered.
(8) tunnel lighting control
Illume control subsystem basically is mixed by detector of brightness of hole inside and outside area controller is finished, change of the data of brightness of hole inside and outside that the basis detects, traffic and by day, the circumstance such as the night, accuse plan to control the illume of channel according to predicted illume, adjust the brightness of the illumination luminaries inside passageway and hole, avoid black hole and white hole effect, the safety that assures drive a vehicle is expedite, in the meantime, the circumstance make known to lower levels that asks in contented illume arrives energy-saving the purpose that move.
