A minimum-intrusive, low-cost, and easy to install system to enhance the reliability of sensors in safety-critical industrial plants

Summary

In safety-critical industrial plants, the requirements on the reliability of critical sensors are extremely high. Such sensors are typically wired and are used for emergency shutdown decision-making, process control, or monitoring. Since these sensors usually work in harsh industrial environments, faults could occur and such faults may lead to unplanned plant shutdowns or serious accidents. Therefore, it is imperative to ensure the measurements of the sensors are precise, accurate and reliable. Deploying additional sensors to validate these measurements can significantly enhance the reliability of the sensors.
安全至上的工厂对关键传感器的可靠性要求非常高。传感器一般采用有线连接方式，主要用于进行紧急停车决策、工艺控制或监控。传感器的工作环境以恶劣的工业环境为主，传感器可能发生故障，从而引起工厂的意外停工或严重事故。因此，必须确保传感器测量值的精确性、准确性和可靠性。部署额外的传感器对测量值进行验证能极大地提高传感器的可靠性。
Researchers at The University of Western Ontario have developed a minimum-intrusive, low-cost, and easy to install system to monitor and validate the existing critical wired sensors. Additional sensors are installed and their measurements are wirelessly transmitted to a computer workstation using very low-power and highly-reliable transmitters. The workstation also obtains the measurements from the existing wired sensors. Then it automatically detects faulty sensors and alerts the plant personnel. As a result, the reliability of the sensors is enhanced, and plant safety, availability, and economics can be improved significantly.
