Preview: Hiltron at CABSAT MENA 2011
Hiltron's primary role is the provision of turnkey systems including design, manufacturing, supply, installation, commissioning, training and support. The company offers complete solutions for fixed and mobile microwave broadcast links; DVB MPEG DSNG systems; L Band and IF Band fibre-optic systems; DVB-T encoding and multiplexing headends; ATM/SDH/PDH/IP transport networks; DVB-S/S2 satellite uplink stations for TV, radio and data transmission; VSAT systems, TVRO systems for cable headends or terrestrial retransmission; and IPTV headend antenna systems.
At its headquarters in Backnang near Stuttgart, Hiltron designs and manufactures redundancy-system controllers; fibre-optic and waveguide switches; remote monitoring and control systems including SNMP; motorised antennas; satellite antenna de-ice controllers; L Band splitters and L Band matrices. New purpose-built premises, completed in 2009, include a large technical operations area with high access doors and ceiling capable of accommodating satellite-link vehicles complete with antennas.
New at CABSAT MENA 2011: Hiltron HDCU-E satellite antenna heating system
Latest addition to the Hiltron product range is the HDCU-E, a combined ice-sensing and dish-heating system for use with large satellite antennas in high-altitude or high-latitude locations. It is capable of handling up to 450 kW of heating power assigned across multiple heating groups. Each group is divided into three independently controlled heater arrays. Each array in turn feeds up to three antenna heater circuits. A four-group configuration, for example, allows control of 12 arrays addressing a total of 36 heating circuits. This modular control approach permits easy configuration of parameters such as antenna size, number of heater pads and the power requirement of each pad. Snow detection is via a reflective sensor with a polarising filter.
Maintenance, monitoring and control of the HDCU-E are via a standard Web browser allowing easy local or remote supervision. All status messages relating to the heating circuits and the de-icing process are displayed, ensuring easy monitoring and adjustment of individual settings and thresholds. All parameters and status messages can also be controlled via SNMP and Web-interface. USB and 100 Mbit/s Ethernet LAN interfaces are provided. Electric currents levels throughout the HDCU-E are continuously evaluated. Malfunctions such as insufficient or excessive heater pad current, or too high a panel temperature, are automatically detected and displayed. Each heater circuit is individually supervised and controlled via user-adjustable minimum and maximum thresholds. Sequential switch-on is performed within the controller to prevent rapid changes in current load when the antenna heating process is activated or deactivated. Sequence timing is user-configurable.
