Intelligent Guide Communication System of Expressway

Background

Vehicles density, weather condition, road condition are different in different cities. In order to reduce traffic accidents, improve transportation efficiency, predict operation information by section and sync weather information, provides accurate, reliable traffic information. For example： traffic stream info, visibility, wind power, rainwater, ice and snow, formulates optimum route and safety protection measures. Integrate data collector of different ports, display terminals and cloud data to a communication network, require excellent products series, abundant projects experiences, and powerful technology planning ability.

Requirements

Various BUS ports transmission supported, such as RS232/485/422

Open network solution, compatible with private network and public network as well cloud data

High-reliability, seamless connect to various auxiliary system, such as video monitoring, peccancy.

Various security mechanism, against data falsify

Physical ports bypass technology, data forwarding continue if ports fault

Solution

Serial servers of Houshi are used to connect sensor of data collector with data display terminals, by means of Ethernet ports to connect all nodes of this road section, formed a small ERPS ring network. Meanwhile, serial server can choose the function of port bypass, single node circuit fault dose not effect data transmission IS3000 Industrial Switch via fiber ports form backbone fiber looped network, to ensure the stable communication function of data collection and guidance data. Meanwhile enable the function of port binding and access filter, secure the data of data server.  IS3000 industrial switch in administration center  is compatible with the network of video monitoring, peccancy, weather forecast, that can predict more accurate guidance information.
