At key points in the railway network, specialised signalling equipment provides local management of railway line safety. Kingfisher RTU’s are utilised for the remote management and co-ordination of these single purpose safety devices. Each Kingfisher RTU maintains a timestamped log of every command sent to a signalling unit from the control room, the digital outputs from the signalling units to field equipment and the changes in status of field equipment. The logging of every event ensures that no historical data is lost, even if there is a breakdown in site communications. In addition, if an audit or post incident review is ever conducted, the log provides the information required to reconstruct the site status at a particular point in time.
Multiple devices work together in unison in railway control. In addition to signalling equipment, there are UPS systems, station lighting, arrival information systems and switchgear. Operators need to be able to monitor and control each and every device. Kingfisher RTU’s provide a single, reliable interface to these systems. The RTU supports numerous data protocols to gather data from and send commands to the myriad of devices used in railway control. With over 20 communications ports available, a Kingfisher RTU can connect to every device on site and still have ports spare to provide redundant communications paths between the site and central control room.
