This is made possible by a combination of rugged, compact computing equipment that can handle the punishment of vehicular use; integration with GPS functionality that enables location-based services; and increasing integration of computers into the vehicle itself. But how does it all work?

Imagine a small, rugged system unit that can be located anywhere in the vehicle, out of the way. That system unit is connected to a vehicle display that can be operated both via touchscreen and via programmable function keys.

The system unit can be used to communicate via standard COM ports with such legacy peripherals as printers or barcode readers. It can also communicate with the vehicle directly through a CAN-bus. CAN stands for Controller Area Network and is a vehicle bus standard that lets various systems and devices communicate with one another. This way, the computer might access door locks, temperature controls, alarms, diagnostics, etc.

Finally, the computer could also access numerous sensors informing about temperatures (crucial in refrigerated trucks), pressures, and all sorts of other variables. All of this information could be processed and used for fleet management and mobile resource management purposes.

Now add GPS and advanced data communication technology, and you have all the components for very sophisticated management systems that move data and information back and forth between vehicles and their dispatch or home base. The opportunities are almost endless.

This is what Advantech had in mind when they introduced the TREK-510 in-vehicle computer and its accompanying TREK-303 smart vehicle display.

The Advantech TREK-303 Smart Display

As is, the TREK-303 touch panel, which measures 9.5 x 6.3 inches and is 1.6 inches thick, is compact enough for tight spaces, yet the display is large enough to be useful and easy to use in all sorts of fleet management and dispatch applications. It also has a tough but lightweight housing that is compatible with RAM mounting solutions so that customers can easily install it according to their requirements.

Below you can see the Advantech TREK-303 smart display from the front and all sides.

Vehicle computers and displays are often subjected to very wide temperature ranges, and so Advantech made sure the TREK-303 meets the requirements for automotive grade working temperatures with an exceptionally wide -22 to 158 degrees Fahrenheit (-30 ~ 70 degrees Celsius) operating temperature range. And while most TREK-303 displays will be mounted inside vehicles away from rain or splashing, the TREK-303 does carry an IP43 rating (protected against solids larger than 1 mm in diameter and against water spray to the front) for the whole device, with everything but the I/O ports actually sealed to IP54 standards (protected against dust and also against water spray from all directions). The unit has also been vibration-tested in accordance with MIL-STD-810G, SAE J1455 4.9.4.2.

The TREK-303 was designed from the start with drivers in mind. For example, powering up the system or waking up can easily be done from a switch in the back of the TREK-303 (see picture to the right); there is no need to go through software and complex sequences. For night driving, the display has an auto-detecting light sensor to automatically adjust brightness for optimal viewing.

But now on to the second part of this system, the Advantech TREK-510 in-vehicle computer.

The Advantech TREK-510 In-Vehicle Computer

"Targeted" performance means as much as is required, no more and no less. With the TREK-510, Advantech provides just that. The system is powered by an unassuming ARM9-based RISC SoC (System-on-Chip) running at 333MHz. That's enough to run Windows CE, Microsoft's equally unassuming workhorse mini-OS that's been used for embedded industrial applications for almost 15 years. It isn't fancy or pretty, but it does the job. It is also quick, simple, fits in with existing Microsoft infrastructure and programming tools/expertise, and it is not burdened with the unneeded complexity of a full OS such as Windows 7.

As you can see above, the TREK-510, which measures just 10.3 x 4.9 x 2.3 inches and weighs 3.3 pounds, is an exceedingly compact unit. It has a steel chassis, blue plastic end caps, and then a finned aluminum heatsink on top. For access to the interior of the unit, remove five small Philips head screws. The inside is neat and clean and well designed, as we'd come to expect from Advantech. The motherboard measures 190 x 120 mm and has all of its external ports mounted right on the board. Note the SD Card slot on the bottom. What you can't see is a small WWAN board that is mounted to the bottom plate of the unit. It included a SIM card caddy for GSM-based data communications.

For I/O, the TREK-510 far exceeds what one would expect from a simple Windows CE-based system.

On the front, the TREK-510 has:

• RCA Mic in
• RCA Line out
• USB Host (standard connector)
• USB Client (Mini-B connector)
• SD Card slot
• Reset
• WWAN antenna port

• 1 DB9 RS232/RS485 serial port
• 2 DB9 RS232 serial ports
• 1 DB9 DI/DO port
• 1 CAN port
• Smart Display port
• GPS antenna port

Additional thoughts about TREK-based Mobile Resource Management systems

It is hard to overestimate the potential benefit of mobile resource management. Intelligent fleet monitoring can revolutionize the way a business is run. In addition to basics like theft protection, dispatchers and fleet management know at any time where their vehicles are, what routes they have run, what the odometer reading is, and whether they are being used according to plan and policy.

An advanced system may not only provide vehicle location on a map, geofences, remote alarms and door unlocking, but also detailed history reports that can show hourly usage, violations, speeding, or many other parameters. (The picture above shows one of many utilities Advantech makes available with their TREK systems.)

All sorts of special sensors can be used to retrieve information from the OBD-II onboard diagnostics system that has been mandatory in vehicles sold in the United States since 1996. OBD-II tracks dozens of vehicle functions, and that data could be used to provide fuel efficiency data, warn of potential vehicle and component failures or manage maintenance requirements. And the industry is just beginning to meld the up to now completely separate world of vehicle computers, generally known as ECUs (Engine Control Units), with computers and communication systems as we know them.

If all this sounds enormously complicated, it is and it's not. Installation of a GPS vehicle tracking system is inherently no more difficult than that of a car audio system. Setting up web-based tracking reports is simple as well, and can be done both for individual vehicles as well as for small and large fleets.

How much does it cost? That depends on the type and system as well as the software it comes with. Developers and systems integrators may use the rugged Advantech TREK platform to create simple or complex vehicle and fleet management systems. IT departments may build their own applications using Advantech tools and standard Windows development environments. TREK based systems may be deployed as inhouse applications, or sold as turnkey or subscription-based systems.

Mobile Resource Management and GPS-based M2M systems are becoming increasingly popular as they easily pay for themselves with the theft protection and peace of mind they provide. They can also generate potentially dramatic savings and increased efficiency in commercial fleet management applications.

In summary, the Advantech TREK-510/TREK-303 combo, when placed in a vehicle, offers a simple, cost-effective platform that can be used in numerous ways to integrate fleet operations more closely into overall corporate information systems, something that can have direct, and substantial, impact on the bottom-line. -- Conrad H.
