Trailer telematics boosts bottom line<br />

By Doug Myers, Director of Sales and Marketing, Transport Refrigeration Inc., Madison, Wisc.<br />

The use of telematics devices in our industry<br />

has dramatically changed how we interact<br />

with drivers and customers, as well as<br />

internally within our own companies. The<br />

rate of innovation in this field has been<br />

remarkable, and the data now available<br />

allows fleet operators to manage their assets<br />

more effectively than ever.<br />

The most common definition of telematics<br />

is “the long-distance transmission of<br />

computer-based information.” In the early<br />

days, satellite transmissions were the norm.<br />

Over time, we evolved into cellular technology,<br />

which has reduced the cost and increased<br />

the frequency of each transmission.<br />

When we look at the use of telematics<br />

in trailers, there are two distinct groups:<br />

refrigerated and dry. The most common<br />

form of telematics used is a simple tracking<br />

mechanism that provides GPS data such as<br />

location, speed, and a history of the trailer’s<br />

movement. This data can boost return on<br />

investment (ROI) by improving trailer utilization,<br />

identifying excessive dwell time,<br />

and finding lost or stolen trailers. Looking<br />

beyond these simple data points, there<br />

is much more information available if we<br />

increase the resolution and communicate<br />

more often. Using the cellular network, we<br />

now have that gateway.<br />

In a dry trailer, we can add devices such as<br />

door sensors, electronic locks, and tire pressure<br />

monitoring systems (TPMS) to speed<br />

When we look at the use<br />

of telematics in trailers,<br />

there are two distinct groups:<br />

refrigerated and dry.<br />

up the ROI and provide a more comprehensive<br />

tool. This requires a system that can<br />

communicate cost-effectively many times<br />

per day or whenever a significant event<br />

occurs – for example, door open/close, tire<br />

pressure high/low, or tire temperature high.<br />

Events can also be used to trigger an alert<br />

to a fleet manager that a condition exists.<br />

With proper telematics hardware, a tire<br />

condition can be identified on a drop trailer,<br />

giving the manager an opportunity to correct<br />

the issue before the trailer is under load.<br />

With a reefer trailer, the amount of data<br />

now available is even greater.<br />

Today’s refrigeration units incorporate<br />

robust electronics<br />

systems to communicate with<br />

telematics. The units actively<br />

monitor the various temperature<br />

sensors, the mode in which<br />

the unit is running, and any<br />

alarm conditions. The telematics system<br />

can utilize the reefer battery, giving us<br />

access to nearly unlimited power. Like the<br />

dry trailer, we can add the door sensors,<br />

locks, and TPMS to improve the ROI. Another<br />

useful feature is the ability to add fuellevel<br />

sensors and additional temperature<br />

sensors to cross-monitor the temperatures<br />

given from the unit microprocessor. This<br />

can be helpful when building a cold-chain<br />

compliance plan, as you have data backed<br />

up from two sources – the unit and an<br />

independent sensor.<br />

By employing today’s technology, a trailer<br />

telematics system can provide so much<br />

more than tracking information. You can<br />

incorporate the multiple data points into<br />

your operation to limit downtime, preemptively<br />

address issues before they escalate,<br />

and drive down the overall cost of each asset.<br />
