“…Thus, we can separate the labels from each other using time-frequency information. As a result of the separation of the identification codes, we use the information on the modulation of the signals of each tag, that is, obtain the temperature value of each tag [5]. Therefore, for the collision case, this solution can be implemented in monitoring systems and control the temperature of high-voltage parts of electric power equipment.…”

Abstract. This paper describes temperature measurement in the multisensor systems based on the radio-frequency identification SAW passive tags which are currently applied in the electric power systems and the switchgears. Different approaches of temperature measurement in the collision case are shown here. The study is based on the tag model with specific topology, which allows us to determine temperature through the response signal with time-frequency information. This research considers the collision case for several passive tags as the temperature sensors which are placed in the switchgear. This research proposal is to analyze the possibility of using several SAW passive sensors in the collision case. We consider the using of the different typical elements for passive surface acoustic wave tag which applies as an anticollision passive sensor. These wireless sensors based on the surface acoustic waves tags contain specifically coded structures. This topology makes possible the reliability of increasing tag identification and the temperature measurement in the collision case. As the results for this case we illustrate simultaneous measurement of at least six sensors. IntroductionModern solutions in the field of monitored parameters should meet the requirements of increased noise immunity. In addition, they should have high speed, resistance to external climatic influences, high reliability and durability in operation. Modern monitoring based on radio frequency systems should be passive (without any energy source). Such requirements are met by radio frequency identification (RFID) technology, based on the use of passive acoustoelectronic devices on surface acoustic waves (SAW) [1], [2].For temperature monitoring, RFID reader interrogates several passive SAW tags which are placed on the monitored object. However, in the simultaneous monitoring of several temperature sensors is limited to the problem of collision for passive acoustoelectronic RFID devices. In the case when several sensors are interrogated simultaneously, their response signals can overlap each other in the time domain, making it impossible to read the code of each device and obtain information about the temperature.The last analysis shows that solutions cannot satisfy the actual tasks of monitoring and control objects with a wide temperature range and certain operating conditions in the collision case. This problem is the most evident in multisensory systems which are using the electric power systems. The temperature is the most important indicator of the electrical equipment current status. It makes possible to provide information about the emergency and electrical fire caused by short circuit or overheating of the equipment in the switchgear. Monitoring systems which are applied for temperature measurement would increase reliability and safety of high-voltage equipment.
