ELECTROMAGNETIC SENSING OF COMPONENTS IN ELECTROMAGNETIC COMMUNICATION AND METHOD

摘要

A system of a machine includes a network of a plurality of sensing/control/identification devices distributed throughout the machine, each of the sensing/control/identification devices associated with at least one sub-system component of the machine and operable to communicate through a plurality of electromagnetic signals. The system also includes shielding surrounding at least one of the sensing/control/identification devices to contain the electromagnetic signals proximate to the at least one sub-system component. The system further includes an electromagnetic sensing system to read the plurality of electromagnetic signals for detection of at least one condition of the sub-system component of the machine. The system yet further includes a remote processing unit operable to communicate with the network of the sensing/control/identification devices through the electromagnetic signals.

1. A system of a machine, the system comprising:
a network of a plurality of sensing/control/identification devices distributed throughout the machine, each of the sensing/control/identification devices associated with at least one sub-system component of the machine and operable to communicate through a plurality of electromagnetic signals, wherein at least one of the sensing/control/identification devices comprises:
a first stage including:
a rectification and power conditioning module configured to receive electromagnetic (EM) transmissions from an EM transmitting source and convert said EM transmissions to electrical power for the device;a communication interface module configured to receive power from the rectification and power conditioning module and at least one of receive the EM transmissions or transmit EM communications; anda control module configured to receive the EM transmissions from the communication interface for processing or preparing the EM communications for transmission from the communication interface module;a second stage including:
a tunable control module, the tunable control module configured to process and convert instructions or commands from the control module of the first stage into analog or digital signals and generate and transmit an output signal;a hardware circuit module to condition the returned sensor signal for use by the control module in the first stage; andat least one connection between the first stage and the second stage to enable communication between the first stage and the second stage; shielding surrounding the at least one of the sensing/control/identification devices to contain the EM signals proximate to the at least one sub-system component and prevent outside interference from a cyber-security or environmental EM interference; an EM sensing system configured to read the plurality of EM signals for detection of at least one condition of the sub-system component of the machine; and a remote processing unit operable to communicate with the network of the sensing/control/identification devices through the EM signals.
