FT Protocol
By selecting one of the type (FT Protocol) option from pull-down-menu, Millennai/DX FT system can communicate
with the hardware with faster DX-BUS polling cycle speed.
117 sensors per second
That's the processing speed of Rel-Tek's new "Millennia-FT" software and telemetry. Speed was measured on an actual 18-sensor system,
clocking 392 scan cycles per minute - an cycle repeat delay of 0.15 sec. Equally significant is that after 3 days running and 30 million
data updates there were zero errors. Not one. That's a communication reliability of 99.9999967%, and counting.
This recent test confirms the results of a very large system test conducted last year. That system was fully loaded and had an
update delay of 3.5 sec. "FT" stands for "Flash Telemetry", a theoretical idea. On implementation, though, it far exceeded our expectations.
Communications is the backbone of any monitoring system. Without good speed and reliability, a telemetry system isn't worth anything.
Rel-Tek released its "Flash Telemetry" monitoring and control package last year. To date, there are four systems operating in underground US coal mines.
Another system is scheduled for shipment July 1, 2010.
The extreme speed and reliability of this "FT" technology reflects Rel-Tek's software prowess and the clever integration
of telemetry with field outstations. Akin to ZIP files, the data stream is compacted for max density. The actual data
rate is 19.2KB, transmitted over inexpensive twisted-pair cable.
High-speed repeaters are placed at one-mile intervals, extending a system to 20 miles straight ahead, while handling
lateral branching as required. LAN, fiber and wireless WiFi data-highway interfaces are also available.
Our gamut of MSHA-approved and classified intrinsically safe sensors use generic 4-20ma analog signals, converted at the
outstation using 12-bit resolution for just 0.0244% digitizing error. Sensors include CO, O2, CH4, smoke, temp and pressure.
Air velocity, humidity, vibration, H2S, SO2, and CO2 are also available for use with the system. Generic is good.
MagiKal is a powerful utility for automatically calibrating hard-to-reach sensors - i.e. high overhead, in pits, over conveyors,
inside silos, under unsupported roof, behind seals and such. It runs under the Millennia-FT package. Calibrations are implemented
on a monthly schedule.
Other news -- Applications of Millennia-FT and gas sensors in "Refuge Alternatives" will include MagiKal to maintain sensor
accuracy over years on standby, unattended. MSHA approval for Rel-Tek's "awAIR" shelter monitoring systems is pending.
Included, is networking with the surface.
Large and small mines can benefit from these new technologies.
