    • Systems and methods are described that collect spatio-temporal data using an RFID system that is capable of locating the spatial position of a sensor, which is typically unaware of its location. Such systems and methods can be contrasted with conventional RFID systems in that they are able to determine the location of sensors in space as opposed to with respect to read zones related to the underlying RFID reader infrastructure. One embodiment includes an RFID system having a plurality of read zones and configured to obtain the spatio-temporal state of sensors within a sensor cloud, where the spatio-temporal state of each sensor includes sensor information, a time stamp, and a spatial location specified independently of the read zones of the RFID system, a spatio-temporal database configured to store spatio-temporal state of a plurality of sensors over time, and an application server configured to trigger events based upon the detection of at least one condition by applying at least one filter to the data within the spatio-temporal database.
    • 描述了使用能够定位通常不知道其位置的传感器的空间位置的RFID系统来收集时空数据的系统和方法。 这样的系统和方法可以与常规RFID系统形成对比,因为它们能够确定传感器在空间中的位置,而不是相对于与底层RFID读取器基础设施相关的读取区域。 一个实施例包括具有多个读取区域并被配置为获得传感器云内的传感器的空间 - 时间状态的RFID系统,其中每个传感器的时空状态包括传感器信息,时间戳和指定的空间位置 独立于RFID系统的读取区域,被配置为随时间存储多个传感器的时空状态的时空数据库,以及被配置为基于通过应用至少一个条件的检测来触发事件的应用服务器 至少一个过滤器到时空数据库内的数据。
