Satellite Based Tracking and Data Device with Multi-Function Radio Frequency Interface

摘要

A remote monitoring device is described that includes a microprocessor, a location determination unit connected to the microprocessor and operable to determine a location of the remote monitoring device. One or more interfaces connect the microprocessor to one or more sensors, wherein the one or more interfaces includes a multi-function radio frequency interface to communicate with wireless sensors. A radio frequency identification (RFID) interface interacts with RFID readers using the multi-function radio frequency interface, and a configuration interface to allow a user to configure the monitoring device also uses the multi-function radio frequency interface. The monitoring device uses a transmitter to transmit the location, status and collected information.
