Abstract: Embodiments of the present disclosure provide systems and methods for determining temperature profile associated with a thermal storage tank of a hydronic system. The method performed by a control unit includes monitoring a flow rate and a temperature of a volume of hot water and a volume of cold water entering a thermal storage tank via a set of flowmeters and a set of temperature sensors, respectively. The method includes determining a current location of plurality of water layers in the thermal storage tank. The method further includes computing an average temperature value of the at least the hot water and the cold water withdrawn from the thermal storage tank. The method includes generating a temperature profile of the thermal storage tank based at least on the current location, the flow rate and the temperature of the hot water and the cold water, and the average temperature value.

Abstract: A system and method of secure asset management comprising an RFID tag attached to an asset, a portable computing device equipped with an RFID transceiver, an inspector RFID authentication badge, and a central database server. The RFID tag includes historical management records of the asset and a cryptographic hash calculated over relevant information to ensure security and authenticity thereof. The portable computing device can read from and write to the RFID tag and read from the RFID authentication badge. Management tasks to be performed by the inspector are determined by the portable computing device based on the authorization level of the inspector read from the RFID authentication badge and the asset information read from the RFID tag. Upon completion of asset management, historical management records are generated by the portable computing device and securely written to the RFID tag by including a cryptographic hash calculated over the relevant information.
