Description
Technical Field
The invention belongs to the technical field of street lamp fault detection, and particularly relates to an intelligent street lamp fault detection method based on the Internet of things.
Background
Street lamps are indispensable facilities for urban night illumination, but the street lamps can not be used for continuous illumination due to the fact that the street lamps are out of order due to the fact that the working time reaches the service life or other reasons. Therefore, the working condition of the street lamp needs to be detected, so that the street lamp can be maintained in time when the street lamp breaks down, and the normal urban lighting requirement is met. However, as the number of street lamps is continuously increased, the range of street lamps is also continuously expanded, and accordingly, the number of street lamps is also continuously increased. Therefore, how to effectively detect the fault of the street lamp so as to timely maintain the street lamp when the street lamp is in fault becomes a difficult task.
At present, the common detection mode of street lamp fault is: and detecting the current value output by a current transformer of the street lamp by using a detection unit, comparing the current value with a preset amplitude threshold, and judging whether the street lamp normally works or not according to the comparison result. If the detected current value is larger than a preset amplitude threshold, judging that the street lamp works normally; and if the detected current value is smaller than the preset amplitude threshold, judging that the street lamp has a fault.
However, there are certain limitations to this approach. For example, for a street lamp including a light emitter and an inductive ballast, or a street lamp including a light emitter and an electronic ballast, the failure location may be the light emitter itself or the ballast. The failure of the light-emitting body or the failure of the ballast can cause the street lamp not to normally emit light. For example, when an inductive ballast fails, in many cases, it is a short-circuit fault, and the current flowing through the street lamp does not change significantly. Therefore, if the electronic ballast of the street lamp fails or the inductive ballast fails, the failure detection cannot be performed in the above manner, in other words, the failure detection of the street lamp by the above method has a problem of high false-positive rate.
