@Bert22306: you are right, the technology to dim based on ambient lighting and/or motion / occupancy sensing is so old that the products are available as commodities. These individual sensor no doubt can be improved to perform more functions.
@elPresidente: your pun aside, there are benefits to using position/attitude sensing enabled light posts in the system. For example, if an area is undergoing settlement of the soil, seismic motions, etc., the sensor data can relay the current state of orientation.
Nice write up; though not all aspects of such a smart lighting system has been addressed, the authors describe a system that can be deployed today.
It would be nice to know more on the life cycle of the products mentioned in the smart lighting system -like field replacements, expansion of more functions, additional sensing, etc.
The potential of this application could be best explained with statastical data of a survey on current energy wastage and possible improvements in street light availability, Maintanace charges. Figures speak louder.
I our city cellular repeaters are mounted on to the street light lap posts on several flyovers and bridges.
Main Control point of a cluster of lamps located at one point which could be automated this way.
I think this should ramup slowy so that it doesnt cause jerk in empolyment.
Dunno, sometimes I think that what could be simple is being made unnecessarily complicated, supposedly in the name of efficiency.
One example being remote control of the lights. Aren't street lights individually controlled now, via individual sensors? Those sensors perhaps can be improved, to include the same extra flexibility that the article claimed for the remote control case. Such as, dimming in brightly moonlit nights?
I like the idea of remote sensing that a light is out. But our local utility has gone one step "further." Remote sensing for free. They expect the customers to call it in, AND they have made it really easy to do so. Automatic phone call, 24 hours a day. Plenty of "remote sensing," and they use an existing network to boot!!
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
