    • The inventive RFID Environmental Monitoring System (RFID_EMS) includes an RFID-based Environmental Monitor and Energy Management Logic for reducing energy consumption in active RFID tags used for long-term active sensing of storage and transit conditions of shipping containers. The RFID-based Environmental Monitor consists of an active RFID tag containing an RF transponder, microcontroller, sensors and associated interface circuitry. The Energy Management Logic provides hardware and software which work together, and consists of executable software or microcontroller logic that monitors and regulates energy use by an RFID tag and associated sensors, and may control the state of specialized peripheral circuits on the tag. By reading the RFID_EMS tag, the invention enables the determination of the condition of precision equipment prior to use, including equipment that requires high readiness after long periods of transit and/or storage.
    • 本发明的RFID环境监测系统(RFID_EMS)包括基于RFID的环境监测和能量管理逻辑,用于减少用于长期积极检测运输集装箱的运输条件的有源RFID标签中的能量消耗。 基于RFID的环境监测器包括一个包含射频应答器,微控制器,传感器和相关接口电路的有源RFID标签。 能源管理逻辑提供了一起工作的硬件和软件,并且由可执行软件或微控制器逻辑组成,可以监控和调节RFID标签和相关传感器的能源使用情况,并且可以控制标签上的专用外围电路的状态。 通过阅读RFID_EMS标签,本发明能够在使用之前确定精密设备的状况,包括在长时间的运输和/或存储之后需要高准备度的设备。
