Abstract
Telecommunication is a key element in the control of railway tra c, especially of high
speed trains. High speed railway systems are equipped with sensors and detectors which
deliver valuable information concerning the operation thus providing rail and passenger
safety. ADIF has currently sensors installed at strategic points of the railway routes
to monitor environmental, train and infrastructure conditions. These detection systems
consist of outdoor sensors installed directly on the track and/or catenary and processing
units, which are located in wayside shelters or racks. Local operation sites concentrate the
nearby received information for further transmission throughout ADIF's communication
network to control centres. The communication link between sensors and processing unit
is always wired, which implies high installation and maintenance costs.
This project proposes the substitution of the wired communication link between sensors
and processing unit with a wireless link using ZigBee technology. For that reason an
orientation study is carried out to identify potential railway detection systems for substituting
the wired communication links with a wireless ZigBee interface. Based on this
initial study a ZigBee mesh architecture is proposed, allowing easy network scalability
and path redundancy. An application prototype is designed and developed based on the
speci c needs of the DCDP (Pantograph's Dynamic Behaviour Detection) system. For
this purpose a speci c application pro le was considered, designing and implementing
the particular clusters needed to meet the DCDP requirements. Tests results successfully
prove the feasibility to use ZigBee technology for the replacement of the DCDP wired
links, opening the possibility to further develop the DCDP applications and implement
the solution for other detection systems. Moreover safety studies must be carried out to
meet railway safety standards and ADIF's safety requirements.
