The present disclosure provides a method and a device for detecting a fault of a monitoring device. The method includes: obtaining monitoring data at a preset sampling period, wherein the monitoring data comprises monitoring values respectively corresponding to a plurality of sampling points; calculating a monitoring value change rate between each monitoring value and a following monitoring value based on the preset sampling period; performing normalization processing on each monitoring value to obtain a normalized monitoring value corresponding to each monitoring value; determining a first number of monitoring values each having the monitoring value change rate greater than a preset change rate threshold and the normalized monitoring value greater than a preset monitoring value threshold; judging whether the first number is less than a first preset number threshold; and determining that the monitoring device has a fault if no.

A method and an apparatus for real-time data analysis of water pipe network are proposed. The method includes: step S1: obtaining a current flow data xto be identified, where i is a positive integer greater than or equal to 2; step S2: determining whether a first difference between the current flow data xto be identified and a previous identified flow data xadjacent to the current flow data xto be identified is less than or equal to a preset threshold; step S3: determining whether a second difference between a next to-be-identified flow data xadjacent to the current flow data xto be identified and the previous identified flow data xis less than or equal to the preset threshold in response to the first difference being greater than the preset threshold.

The present invention relates to a method for detecting fire with light section image to sense smoke. Infrared radiation arrays ( ) and infrared cameras ( ) are provided in a monitored area. The images of the infrared light spots transmitted by the infrared radiation arrays ( ) are converted into video signals by the infrared cameras ( ), and transferred to a video switcher ( ). The video switcher sends the video signals received from the infrared cameras to a computer ( ) one by one. The computer processes the signals. If fire is sensed, the computer controls the alarm unit ( ) to alarm by a linkage.
