Signal Control System for Subway No. 1
Subway No. 1 from Liuyuan to Shuanglin has a total
length of just over 26 km, including almost 14
km underground. The subway has 22 stations, one
train-distribution center, one train storage
area, and a distribution control center. The
trains use 750 VDC third-track power. To give
you an idea of the complexity of the system,
there are 4 bulk substations, 6 propulsion power
substations, and 3 voltage-reduction substations,
with signals transmitted by an ATP, ATS system.
Baifeng Tunnel Monitoring System
The rapid development of China's domestic economy
has led to an increase in the number of highway
and tunnel construction projects being conducted
around the country. In the interest of maintaining
a secure and safe highway and tunnel system, much
emphasis is being placed on building robust tunnel
monitoring and control systems. Western countries
began researching advanced tunnel control systems
in the 1960's.
