Wireless interface for a plurality of transducers
First Claim
1. A method, comprising:
- monitoring, by a first transducer of a plurality of transducers, a first surrounding physical condition;
receiving, at a processor, a transducer identification signal from the first transducer;
identifying, by the processor, and responsive to the received identification signal, a transducer type of the first transducer;
providing transducer requirements to the first transducer based on the identified transducer type, wherein the transducer requirements include a bias voltage;
compensating an output of the processor based on the identified transducer type;
receiving, at the processor, a transducer output signal indicative of the monitored first surrounding physical condition;
detecting, by the processor, a quantity of transducers in the plurality of transducers;
selecting a transmission mode based on the identified transducer type and on the detected quantity of transducers, wherein selecting the transmission mode includes selecting a different frequency based on the identified transducer type and on the detected quantity of transducers; and
transmitting, via the selected transmission mode, a wireless signal indicative of the output signal.

Abstract
A wireless interface system that interfaces with any one of a plurality of transducers of different types, such as pressure sensors, temperature sensors, and current probes. The transducers employ identical connectors with a common connecting scheme. In this manner, any transducer can be connected to a wireless interface which has the same input connection scheme. When the wireless interface is connected to the transducer, a rechargeable battery, which is associated with the wireless interface, is activated. The wireless interface then determines the type of transducer being utilized and provides sufficient circuitry as well as determining the requirements of the connected transducer. In this manner, the wireless interface, besides recognizing and determining the type of transducer, can determine the range of the sensor and can provide specific circuitry to be activated to supply power and to read data from the sensor via common output pins.
