W
ith the rapidly expanding deployment of digital railway technology, there
is a growing need to remotely monitor and control the operating environment of sensitive equipment in technical control rooms throughout the rail network. Higher levels of control and monitoring for cooling and other key parameters are now possible at the rack and system level. Two key elements to advanced
remote environmental monitoring and control are:
1 - MANAGEMENT GATEWAY This provides an environmental monitoring platform designed to sense, track, store and set alarms for health and security parameters in an IT datacentre infrastructure. Using built in Web Interface, security features, sensor configuration, user management, alarm and log management can be set up. Main access to the Management Gateway will typically be through a 1 GBE Network interface, supporting industry standard protocols like SNMP, SMTP, HTTPS, BACnet, Modbus/TCP and HPI. At the heart of the nVent
SCHROFF Guardian Management Gateway platform is a compact 1U high, 250mm wide, control unit which can be installed as a rack assembly or into any available space in a datacentre cabinet, and may be AC or DC powered. The nVent SCHROFF system offers three sensor management ports with each port being able to monitor up to 16 sensor or devices with a total cable length of 40 meters per port. This allows a single Management Gateway unit to monitor multiple racks or complete rack aisles. As well as monitoring physical
parameters such as temperature, humidity, smoke, door status or water intrusion, the nVent SCHROFF Management Gateway provides easy plug and play installation to monitor their RackChiller coolant distribution unit, and In- Row Coolers.
2 - SMART FAN TRAY In conjunction with a Management Gateway a Smart Fan Tray with remote management provides monitoring and control of the internal environment of equipment cabinets, an essential requirement for the reliable function of digital railway technology systems. A Smart Fan Tray can also provide the ability to set alarms for predictive maintenance should the fans start to lose rotation speed.
REMOTE SMART HARDWARE MANAGEMENT FOR DIGITAL RAILWAY TECHNOLOGY
In this article, Dave Martin, director of business development at Foremost Electronics, examines solutions for remote monitoring and control of the sensitive equipment in rail network control rooms
The nVent SCHROFF Smart Fan Tray
provides remote control and monitoring through an ethernet connection to the Guardian Management Gateway. It manages energy efficiency by providing temperature controlled fan speed as well as control of acoustic noise through temperature dependent air flow. The 1U, 19” fan unit is fitted with three efficient and reliable fans and the front panel has a function control and LED status indicators. A relay status signal is available, and contact protection is in accordance with DIN EN ISO 13857.
