Radio-Frequency System for Remote Monitoring of the State of Protective Containers with Hazardous Substances

摘要

Abstract In this paper we present the results of the development of a radio-frequency system for remote monitoring of the state of protective containers with hazardous substances based on energy-independent transponders, which provide estimating the entire set of indicators of the state of the packaged cargo. The operating principle of the system is shown. The design of a transponder containing a radio tag based on surface acoustic waves using a multi-strip coupler, which provides switching signals from physical impact sensors, transmitting object identification data and reliable information about the current state of the product at the time of the survey, is considered. The experimental responses of the pulse responses of radio tags are presented. A practical implementation of a radio-frequency monitoring system that passed state tests is presented.
