Zero-Overhead Monitoring of Remote Terminal Devices
AbstractThis paper presents a method of delivering diagnostic information from data acquisition terminals via legacy low-throughput transmission system with no overhead. The solution was successfully implemented in an intrinsically safe RFID system for contactless identification of people and objects developed for coal mines in the end of 1990s. First, the goals and main characteristics of the application system are described, with references to underlying technologies. Then transmission system and the idea of diagnostic solution is presented. Due to confidentiality reasons some technical and business details have been omitted.
