Infrared sensor array based temperature monitoring systems for data centers and related methods
First Claim
1. A temperature monitoring system for a data center that includes a plurality of aisles and a plurality of equipment racks that are mounted in rows between the aisles, the temperature monitoring system comprising:
- a plurality of overhead-mounted infrared sensor arrays that are mounted above the aisles and/or the equipment racks, wherein each infrared sensor array includes a two-dimensional array of infrared emission sensors, and at least some of the infrared emission sensors have field of view patterns that project onto aisle faces of the equipment racks; and
a controller that is remote from at least some of the infrared sensor arrays and that is in communications with the infrared sensor arrays, the controller configured to provide a two-dimensional thermal map of the aisle faces of the equipment racks based at least in part on temperature data received from the infrared sensor arrays,wherein a first of the infrared sensor arrays comprises a substrate that has the plurality of infrared emission sensors on a front surface of the substrate, and wherein a back surface of the substrate is mounted at an acute angle with respect to a plane defined by the floor of the data center,wherein a first of the overhead-mounted infrared sensor arrays comprises a ceiling-mounted infrared sensor array that is mounted on a support that extends downwardly below the ceiling,wherein a first of the infrared sensor arrays is powered via a cable that includes at least first and second conductors, and wherein the information received from the first of the infrared sensor arrays is transmitted to the controller over at least one of the first and second conductors, andwherein the first and second conductors of the cable provide a direct current power signal to a light fixture.

Abstract
Temperature monitoring systems for data centers include a plurality of ceiling-mounted infrared sensor arrays. Each infrared sensor array includes a two-dimensional array of infrared emission sensors, and at least some of the infrared emission sensors have field of view patterns that project onto aisle faces of equipment racks that are mounted in rows in the data center. These systems may further include a controller that is remote from at least some of the infrared sensor arrays and that is in communications with the infrared sensor arrays, the controller configured to provide a two-dimensional thermal map of the aisle faces of the equipment racks based at least in part on temperature data received from the infrared sensor arrays.
