Unit wall temperature screening method and device

The embodiment of the invention provides a unit wall temperature screening method and device. The method comprises the steps of: obtaining a plurality of measurement point temperatures, and respectively comparing each of the plurality of measurement point temperatures with a preset temperature threshold, and selecting the measurement point temperature greater than the preset temperature thresholdamong the plurality of measurement point temperatures to obtain a plurality of measurement point temperatures after primary screening; and selecting the measurement point temperature with the maximumtemperature value among the plurality of measurement point temperatures after primary screening, and displaying a measurement point position of the measurement point temperature with the maximum temperature value. By adopting the unit wall temperature screening method and device provided by the embodiment of the invention, accurate screening can be performed on a large number of measurement pointtemperature data, over-temperature points are displayed in real time and an alarm is issued, thereby reducing the workload of the operation and maintenance personnel and reducing the security risk.
