KNBS Highway Intelligent Dital Broadcasting System
HIGHWAY INTELLIGENT DIGITAL
BROADCASTING SYSTEM SOLUTION
Highway has become the symbol of country modernization. The speed development of transportation network effectively improved our transportation structure and transportation efficiency and play a important role for our economy. Therefore, our country value and control the highway construction.However, with the high-tech construction level of highway, it creates much highway construction miracles. Now we make an achievement in family, enterprises, shipping moll and other field. But we loose manage the highway communication, parts of detection and manual operation. Therefore, our company has mature communication technology and a completely intelligent management communication. It saves labor cost, social cost and leads the world toward intelligent management platform.
2.1 Highway General Station
Setting an IP host server and related software in general station.It makes up digital voice commanding and dispatching system and control center. They can broadcast to anywhere in highway, unified broadcast. People can communicate with toll station and service area freely. And we could control the light and close/on exhaust fan in the whole tunnel through host server.
2.2 Highway Toll Station
Installing one IP server in each toll station, the worker could contact with general station directly through this intercom if any emergency. Our intercom supports one-touching calling and ask help soon.
2.3 Highway Service Area
Installing two sets of emergency telephone in our service area, one is IP phone with loudspeaker, one is IP intercom with broadcasting function. People could talk with general station and also could broadcast the service, play music on time, broadcast notifications and etc.?
Tunnel design needs one IP telephone with large power, some loud speakers. We can receive the broadcast from the manage center,extension station and toll station. And when the IP phone connect with tunnel light and ventilating fan, the host system can send the switch command.
If install some HD detector in each section with 180 ° rotating ultra-high resolution probe,we can stay at control center or the console to detect the status of a certain tunnel or road section.At the same time, we can easily getthe HD video from the console. This design effectively solve the problem which need the bus to detect in the past days.
3.1 Basic Function
Echo detection: The IP telephone itself can detect the working status.And the send the result to host system. The operator could check each
IP phone in control center.
Remote control the tunnel light：when the IP phone connect with tunnel light, the host system can send the switch command.
Remote control ventilating fan：when the IP phone connect with ventilating fan, the host system can send the switch command.
Emergency calling: support call the tunnel rescue center or the police rapidly when in an emergency.
Tunnel detection: Detect the status of a certain tunnel or road section output the HD video from the console.
Unified broadcasting: highway radio management center support broadcast to all toll gates, service area and tunnel.
Group broadcasting: highway radio management center support group the toll gates, service area,tunnel and then broadcast radio or music.
Emergency broadcasting: radio management center support inform other station when in an emergency.
Multiplex broadcasting: toll gates, service area and tunnel station could receive broadcast from different station
Auto-broadcasting: The server could set the timing playlist. Each radio point could auto-play/close the device according to the timing playlist.
Free calling: this system can set control station, radio management and control station could broadcast to any radio point.
Duplex talk: each radio point could freely talk with radio management center or other station.
3.2 System diagram
Control management system centralizes the traditional decentralized system, scheduling, broadcasting, telephone, monitoring, tunnel devices and so on. It reduce the construction cost and the operation is very convenient.
This system supports remote maintenance,IP telephone adapts super advanced echo detection. From host server, we can clearly get the working state of every IP telephone. It completely save cost for artificial detection work in highway. Now only two companies have this technology in the world.
This IP broadcasting system can be applied in tunnel congestion, traffic accidents, fire, and etc. Management center can post information to the tunnel vehicles and organize the team to help channel through traffic. With the high demand of emergency and reconstruction, this system satisfied with strong function. The control center can post information, meanwhile, the leader can remote command the scheduling instruction. This system also applied in office phone system, tunnel maintenance, power supply in tunnel, toll station, radio in service area and so on.
