Operation and maintenance operation method and system for electromechanical system of expressway

The invention discloses an operation and maintenance operation method and system for an electromechanical system of an expressway. The operation method comprises the following steps of S1, numbering street lamps of the expressway; s2, numbering photosensitive sensors and installing thephotosensitive sensors on the street lamps with the corresponding numbers; s3, setting a plurality of threshold values for the photosensitive sensors according to the fault factors of the street lamps; s4, detecting the brightness of the street lamps corresponding to the photosensitive sensors through the photosensitive sensors to obtain a photosensitive detection value; s5, judging the working states of the street lamps according to the threshold value to which the photosensitive detection value belongs; s6, summerizing the working states of the street lamps and analyzing the fault reasons of the fault street lamps; s7, sending the position information of the fault street lamps and the fault reasons to street lamp maintenance p
