Integrated Monitoring System for Environmental Dynamics of Qinghai-Tibet Railway.pdf

1) System Structure

The whole line of the Qinghai-Tibet Railway, from Ge’ermu, Qinghai to Lhasa, Tibet, is located in a cold and harsh alpine region characterized by rolling thunder.  The integrated monitoring system contains an environmental monitoring system, DCC data monitoring system, security, video, monitoring system and fire fighting system. It is composed of a field monitoring end, communication network and central control layer.

The industrial Ethernet switch in the communication network collects the information from the field monitoring control and transmits it to each PC room, which will send it to control by SDH. Based on the characteristics of the region, Lhasa is the monitoring center for the region south of the T'ang-ku-la Mountains and Ge’ermu for that north of the mountains.

2) Network Requirements

Excellent temperature performance, be able to work in extremely cold environment.
Good EMC features, be immune to frequent interference of rolling thunder and train.
Good manageability, easy to manage and maintain unattended station.

3) Product Application

Industrial Ethernet switch KIEN5000 in the station monitoring center and monitoring points of environment factors.
Industrial Ethernet switch KIEN6000 in each branch monitoring point.
Industrial Media Converter KOM300 in the control nodes distant from station monitoring center.
