Enhancing Toll Management Systems: Addressing Common Issues with Loop Detectors

Toll Management Systems (TMS) rely heavily on loop detectors for efficient vehicle detection. However, one common challenge faced in this domain is the barrier occasionally falling on vehicles, often due to detector malfunctions. As loop detectors are a cost-effective solution widely used in TMS, addressing these issues proactively can greatly improve their performance and reliability.

Here are some common causes of loop detector malfunctions and how they can be resolved:

1. Loop Feedline Issues: A damaged or improperly installed feedline (e.g., not twisted properly or touching other electrical wires) can disrupt signals, leading to barrier malfunctions. Solution: Use conduit pipes to protect and properly install feedlines.
2. Power Supply Fluctuations: Inconsistent voltage, such as drops or surges, can affect loop detector performance and result in faulty vehicle detection. Solution: Always use a stable, controlled voltage. If using an SMPC (Switch Mode Power Converter), regularly check the output voltage.
3. Electromagnetic Interference: Close proximity to power lines, relay signals, or other electronic equipment can interfere with the detector's ability to sense vehicles. This is common in areas with dense electronic activity, like toll lanes. Solution: Maintain at least 2 to 3 inches of separation between the loop detector and any such equipment, even when using multiple detectors.
4. Non-Moving Metal Objects: Stationary metal objects near the loop can influence detection accuracy. Solution: Ensure a minimum distance of half a meter between the loop and any non-moving metal.
5. Inductance Value: Low inductance due to an insufficient number of turns in the loop wire can reduce detection efficiency. Solution: Always ensure the correct number of turns in the loop and check the inductance value regularly. (In BBC Bircher Smart Access 's Proloop2, this value is conveniently displayed on the screen.)

By following these preventive measures, TMS providers can mitigate the issue of barriers falling on vehicles and ensure smooth operations. Proloop2, with its advanced features and user-friendly interface, offers reliable solutions to these challenges.
