Abstract:

Electromagnetic interference can cause disruptions to the functional signal on a wired communication channel. Detecting whether the transmitted data has been affected by electromagnetic interference is an important challenge that needs to be addressed. This paper describes an advanced design of an electromagnetic interference detector to detect electromagnetic interference in a wired communication channel, and compares it with the previously proposed adder and subtractor based A&S electromagnetic interference detector. The performance of both EMI detectors is evaluated in light of recently proposed electromagnetic interference condition monitoring definitions. These definitions categorize the received signal based on the impact of electromagnetic disturbance on the transmitted data and its detection by the EMI detector, which helps to determine if the overall detection is contributing towards enhancing safety and/or availability. An in-depth numerical analysis of both electromagnetic interference detectors is performed using a mathematical model. The mathematical model considers different scenarios for the electromagnetic disturbance that is present at the location of the electromagnetic interference detector. These scenarios include varying amplitude, frequency, and phase as well as varying phase differences of the voltages induced by the electromagnetic disturbance in each of the data transmission lines. In addition, the performance of both electromagnetic interference detectors is analyzed in semi-reverberant environments using a Monte-Carlo simulation framework. This research concludes that the Advanced electromagnetic interference detector addresses the inadequacies of the A&S electromagnetic interference detector and can be effectively used for enhancing the safety of wired communication channels.
