    摘要: According to one aspect, a method for remote monitoring of electrical equipment includes acquiring a set of data points, each data point representing a temperature associated with a piece of electrical equipment or a component thereof, assigning each data point to one or more groups of data points, and defining an alarm metric for each group. Each group's alarm metric may be defined independently of other group's metrics. The defined alarm metrics are used to determine the health of the electrical equipment. The data may be determined from virtual probes within an infrared sensor and/or received from RFID devices containing temperature sensor, which are attached to or near the equipment to be monitored, for example. The methods described herein do not require conversion of sensor data into temperature values, and thus obviate the need for expensive sensors and/or computationally demanding conversion, compensation, and calibration routines.

    摘要: In a pyroelectric infrared detector in which a pyroelectric element and an integrated circuit performing processing of a detection signal from the pyroelectric element are housed in a package, the integrated circuit includes: a converter that performs analog-to-digital conversion of the detection signal; a signal processor that performs signal processing by a digital filter for the detection signal after the conversion; and an input-output controller that delivers the output data from the signal processor to an external device via serial data communication. A cut-off frequency of the digital filter is settable and changeable by voltage application to the integrated circuit or by a command supplied from the external device via the serial data communication.
