A street light tube life monitoring system

Abstract

The invention discloses a system for monitoring the life of a street lamp tube, which includes a ballast system and a remote control dispatch center. The ballast system includes a ballast inductor L1 connected to the lamp tube, a compensation capacitor C5 and a high-voltage starter; the remote control dispatch center passes The communication network is connected to the voltage detection circuit set at both ends of the lamp tube. When the high-pressure gas discharge lamp is working, there will be a fixed tube voltage at both ends of the lamp tube. After the voltage is divided by the voltage dividing capacitor C1 and the voltage dividing capacitor C2, the voltage regulator Z1 will divide the voltage. Clamp at a fixed value to protect the voltage detection circuit from being damaged. The detection circuit composed of detection diode D1, resistor R1 and filter capacitor C3 converts the divided high frequency and low voltage into DC voltage V1, and the remote control dispatching center will The DC voltage value is compared with the preset voltage value to judge the life of the lamp tube. When the service life of the lamp tube is about to expire, the remote control dispatching center will timely report the detected lamp life information so that relevant personnel can deal with it in time.

Description

[0001] technical field [0002] The invention relates to a street lamp monitoring system, in particular to a street lamp monitoring system capable of testing the service life of lamp tubes. Background technique [0003] At present, more than 90% of the road lighting uses high-pressure gas discharge lamps. We cannot detect the service life of the lamp tubes. Only when the lamp tubes are completely unusable can we find out and deal with them through manual inspections, which will waste a lot of manpower and material resources and affect normal road lighting. , increase the hidden danger of accidents, and waste electric energy. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a street lamp monitoring system capable of detecting the service life of lamp tubes, prompting replacement of lamp tubes in time, and reducing hidden dangers of accidents. [0005] The technical solution of the present i...
