Abstract
A method of monitoring a health of a temperature system may comprise selecting a temperature sensor of a plurality of temperature sensors arranged in an array, where each temperature sensor corresponds to an address within the array. The method may comprise identifying the address corresponding to the single temperature sensor, sending the address to a multiplexer, and selecting the single temperature sensor using the identified address. The method may comprise testing the selected single temperature sensor calculating an average temperature detected by the plurality of temperatures sensors.
Claims20
A method of monitoring a health of a temperature system, the method comprising:
- selecting a single temperature sensor of a plurality of temperature sensors to test, the plurality of temperature sensors arranged in an array, each of the plurality of temperature sensors corresponding to an address within the array;
- identifying, via a controller, the address within the array corresponding to the single temperature sensor;
- sending the identified address to a multiplexer connected to the plurality of temperature sensors;
- selecting, via the multiplexer, the single temperature sensor using the identified address;
- testing, with the controller, the selected single temperature sensor;
- and
- calculating an average temperature detected by the plurality of temperatures sensors.
A temperature measurement system, the system comprising:
- a plurality of temperature sensors arranged in an array, wherein each of the temperature sensors has a corresponding respective address;
- a multiplexer in selective communication with each one of the plurality of temperature sensors to isolate a single temperature sensor of the plurality of temperature sensors;
- a controller in communication with the multiplexer to identify a single temperature sensor to be selected by the multiplexer;
- and
- test circuitry in communication with the controller to test a health of the isolated single temperature sensor.
