Hurricane Test #1 – The Dorian Job

By | Blog, Uncategorized | No Comments

Wind tunnel testing has its place, but the real-world can be a bit rougher, like hurricane Dorian rougher. Well, maybe that sound a little hyperbolic, but 84 mph wind is still quite a bit.

Our customer reported: “The two Dyacon met stations we currently have running made it unscathed through Hurricane Dorian that just hit us. Max recorded gust from the Dyacon stations was 37.4 m/s (84 mph). . . . Not sure if this is the first CAT 1 hurricane the sensors have been through, but thought you may be interested to know.”

Dyacon sensors have been tested beyond 84 mph on a mobile platform, but this was the first time we have seen this speed in the wild as part of a full weather station.

The map shows the location of the weather station in North Carolina.

The charts below are from DyaconLive. The peak gust measured was 37.4 m/s (83.7 mph). The maximum 10 min average at the same point was 26.9 m/s (60.2 mph).

Telematics-M2M-IoT

Back Up (beep, beep, beep …)

For those of us that have been around the block a few times, it seems like the same (or slightly evolved) technology picks up new names every few years. An observer might think that there must be a Global Market Stimulation bureau somewhere dedicated to reinvigorating technology that they think should be adopted. (Or, maybe marketing people think we won’t noticed that they just changed the name on the same stuff.)

Dyacon began when the rugged, on-board computer products division was separated from the parent company. At the time (2007), the concept of automated data communications from a fixed or mobile asset was called telematics. This was intended to be a little more board than “telemetry,” which would typically just mean the transmission of measurement data.

Later, this evolved into machine-to-machine communication. That name was too long, so it was shortened to M2M, which sounds more trendy.

That still didn’t seem to capture the imagination of society, so Internet of Things was invented. Again, the name was too long, so it was initialized to IoT. Yet, my toaster is still dumb (which I prefer) and my car still has a cassette player (which I don’t prefer since it ate my Simon and Garfunkel Greatest Hits tape–now all it plays is silence). (If you didn’t get the “silence” reference, you probably haven’t heard “telematics” either.)

On-Board Vehicle Computers

Like general telemetry technology, mobile asset telematics has included a similar range of names and applications over the years including: AVL (automatic vehicle location), EOBR (electronic onboard recorder), and ELD (electronic log device).

Dyacon continues to design and manufacture open-programmable computer products for the vehicle telematics market. These products are now branded under ControlTrac.

CT650 is our latest on-board computer. Unlike off-the-shelf industrial computers, CT650 is purpose-built for the vehicle market. It utilizes automotive connectors, is sealed, and compact. The I/O is dedicated to in-vehicle telematics/M2M/IoT applications. So, you won’t find “desktop” on our box; these don’t hold up to the vibration, dust, and abuse of a vehicle environment.

CT650 uses our own custom build of Linux, leveraging the ease-of-use and versatility of an open system, while still providing for unique features. The embedded cell phone, embedded uninterruptible power supply, digital I/O, CANbus (SAE J1939), and multiple communication ports provide an all-in-one computer solution; no external converters or power supplies are required.

ControlTrac computers tie to the vehicle data bus (engine control module) and peripheral devices in order to monitor vehicle activity, operating parameters, and auxiliary sensors. Data may be communicated to the vehicle operator or transmitted by cell phone network or satellite.

Integrators

If the above makes sense, you probably recognize that CT650 is only one part of a larger system and integration project.

Dyacon onboard computers are sold to fleet service providers, which usually employ a team of software developers to provide a complete solution to the end users.

So, if you are providing asset management, road-weather information systems, mobile vehicle diagnostics, messaging, or routing information to fleet managers, Dyacon CT650 may be the right tool for your solution. ”
