Engineering Systems That Won’t Fail You

Picture this: You are flying 36,000 feet in the air, on your way to a family getaway at Disney World, and suddenly the plane experiences a critical system failure. Thanks to the multiple duplicate components and systems on the plane, a new system seamlessly takes over operation of the aircraft, and you and your family safely reach your destination, none the wiser.

The duplication of systems in this scenario is called redundancy, and it’s one of the most common fail-safe methods around. Merriam-Webster defines fail-safe as “incorporating some feature for automatically counteracting the effect of an anticipated possible source of failure.” Fail-safe is further described as “a device or practice that, in the event of a specific type of failure, responds or results in a way that will cause no harm, or at least minimize harm, to other devices or to personnel.”

Redundant, in this sense, means the opposite of its definition “superfluous.” In modern-day aircraft, redundancy is essential to keep systems fail-safe, and people safe.

On the ground, the heavy-duty industry relies on safety systems that help operators mitigate potential collision hazards. The more effective safety systems actively detect and then warn operators when danger is near. But these systems are not inherently fail-safe unless measures are taken to make them so.

Redundancy is not an option in heavy-duty equipment because it is too expensive to duplicate critical systems. Instead, the cost-effective fail-safe measure is to warn the operator if the equipment’s safety system is compromised or becomes inoperable.

PRECO engineering collision mitigationPRECO Electronics has been in the safety business for several decades with a goal of keeping people in heavy-duty industries safe. We are proud to say we are leaders in the industry today doing just that. We design, engineer and manufacture heavy-duty collision mitigation technology so operators and fleets can perform without harm. Not only do our systems actively monitor and alert operators if people and objects are detected in the system’s detection zone, but our technology also warns operators when these active detection systems are not working the way they should.


PRECO’s PreView® Radar Object Detection Systems are continuously performing what is called a Built-In Self-Test to make sure that a system’s sensors are performing to specification. If an issue is detected, a message is sent to the in-cab display unit notifying the operator of an issue. 

PRECO mining safetyEven when environmental factors like a heavy build-up of debris blocks the face of a sensor, PRECO’s object detection systems notify the operator so the sensor can be cleared.

Our systems survive the most rigorous testing in the industry before we even think about putting them on the market. This way, we feel comfortable knowing that our sensors are 100% effective 100% of the time. And if a sensor is compromised, our systems let you know before your safety is compromised.

Every product risks failure. PRECO cares that our products fail safely. That’s why we incorporate a constant self-monitoring system into our object detection safety solutions, so you can work with greater confidence and peace of mind knowing our solutions are truly fail-safe.
