Description
Technical field
The present invention relates to technical field of rail traffic, especially design a kind of column of the region CTCS-1 grades of control data center apparatus.
Background technique
CTCS-1 grades of train control systems are to be suitable for 200km/h or less to create and be transformed route, continuously fast using target range
The train control system of control model monitoring safe train operation is spent, track circuit, which is realized to occupy, checks and provides driving License Info,
Passive balise realizes train positioning, based on communication transmission line fixed data, station route data and interim limit
Fast information.
The technological orientation and functional requirement, the ground that can be realized corresponding security level of CTCS-1 grades of train control systems are set
The radio block center in train control center (TCC) and CTCS-3 grades of train control systems in standby only CTCS-2 grades of train control system
(RBC)。
But if CTCS-1 grades of routes use train control center (TCC), need it is a set of in each station setting, together
When need according to CTCS-2 route in each station track and exit setting active balise and LEU, since both wired yard is complicated,
Website quantity is more, causes improvement expenses huge, wastes the processing capacity of train control center.
If using radio block center (RBC) on CTCS-1 grades of routes, since existing alignment vehicle quantity is more, cross-channel is multiple
Miscellaneous, distance between sites are small, so radio block center needs arrangement closeer, implementation cost is huge, can not also be applicable in both wired net
Network environment.
Summary of the invention
The object of the present invention is to provide a kind of regions CTCS-1 grades of to arrange control data center apparatus, can be adapted for station setting
Computer interlocks the CTCS-1 grade route of (CBI) and center setting temporary speed limitation server (TSRS), saves system cost.
The purpose of the present invention is what is be achieved through the following technical solutions:
A kind of column of the region CTCS-1 grades of control data center apparatus, comprising: fail-safe computer, communications interface unit, channel radio
