Abstract:
1. A streetlight power controller, comprising: an image capturing device operable to capture digital images of at least one route section of a streetlight control area at a predetermined interval, the route section comprising a first terminal and a second terminal; a speed meter, a storage system, and at least one processor; and a power management unit stored in the storage system and executable by the at least one processor, the power management unit comprising: an image analysis module operable to detect whether a moving object approaches the first terminal of the route section, and to determine the second terminal of the route section based on movement of the moving object from the digital images; a route determination module operable to control the speed meter to detect a speed of the moving object, and to calculate an estimated departure time of the moving object departing from the first terminal and an estimated arrival time of the moving object arriving at the second terminal based on the speed of the moving object and a route distance of the route section; and a power control module operable to automatically adjust the intensity of a corresponding streetlight of the first terminal of the route section on the estimated departure time.
