摘要： The disclosure relates to method and system for performing real-time monitoring of a container containing a non-gaseous fluid substance. The method includes receiving, from a sensing device installed in the container and by a monitoring device, a dataset corresponding to the container and to a non-gaseous fluid substance in the container. The dataset may be acquired and transmitted by the sensing device at a preconfigured time-interval and may include level data corresponding to a level of the non-gaseous fluid substance in the container, temperature data corresponding to a temperature inside the container, and movement data corresponding to movement of the container or a lid of the container. The method further includes performing, by the monitoring device, a time-series analysis on the dataset for determining an anomaly; and generating, by the monitoring device, a graded alert based on the anomaly.

摘要： A method of localizing articles comprising passive Radio Frequency Identification Device (RFID) tags is disclosed. The method includes receiving tag information from each of a plurality of RFID tags attached to a plurality of articles fixed to a plurality of immovable assets disposed in a predefined layout within an enclosed region; segregating the tag information received from each of the plurality of RFID tags into a plurality of regions within the predefined layout; mapping an RFID tag from the plurality of RFID tags to an immovable asset from the plurality of immovable assets; and verifying mapping of the RFID tag to the immovable asset based on an estimated physical location of the RFID and an actual physical location of the RFID tag.

摘要： A method and system for dynamically controlling transmit power of a wireless transmitter includes determining a set of sensors based on a location of each of a plurality of sensors, a location of the wireless transmitter, and a maximum range of the wireless transmitter. The method further includes determining a change in power level and a change in interference level at each of the set of sensors based on a plurality of power measurements and a plurality of interference measurements, within a predefined response time, for each of the set of sensors, determining a required change in a transmit power level of the wireless transmitter based on the change in power level and the change in interference level at each of the set of sensors, and dynamically effecting a change in the transmit power of the wireless transmitter based on the required change.

摘要： System and method for generating a dynamic route map for a person trapped in an enclosed space and for enabling quick evacuation of the person is disclosed. When a request for evacuation is made by the person, the evacuation system locates the person based on the RFID person identifier tag and localizes the location of the person with respect to plurality of RFID floor tags and plurality of self-identifying RFID reader antenna tags. Further, condition of the floor is assessed by comparing the RSSI readings of the plurality of RFID floor tags and the RSSI readings of the plurality of self-identifying RFID reader antenna tags and the environmental information with pre-defined baseline RSSI readings of the plurality of RFID floor tags, RSSI readings of the plurality of self-identifying RFID reader antenna tags and an environmental threshold. A dynamic floor map is generated by collecting the RSSI readings from the plurality of RFID floor tags, self-identifying RFID reader antenna tags. Subsequently, the condition of the rest of the floors is assessed by analyzing the environmental information from plurality of environmental sensors and assessing the working condition of RFID tags deployed at each floor. Finally, generating a dynamic route map such that emergency rescue operators can reach out to the trapped person in least amount of time.
