Description

Street light system with remote monitoring

The present invention relates to a remote street light system capable of remote monitoring that can determine the presence of a failure of the street lamp at a remote location to notify the manager in real-time text message.

In general, the street lighting system that illuminates the street is initially equipped with a street light controller that locally turns on or off the circuit breaker manually, but gradually detects the illumination of night and day, or has a street lamp controlled by a program. Automation has been made in the direction of having a controller, and recently, it has been developed into a street light control system that can be remotely controlled using unidirectional wireless communication.

However, such a conventional street light control system can control the flashing of the street light selectively or at the same time at a desired time from a long distance, but the administrator can only control in one direction, so that the failure state of the street light system cannot be grasped in real time. There was this.

This is because the street lamp controller of the conventional one-way street lamp wireless control system can control the lighting of the street lamp wirelessly remotely, but it is possible to remotely check and monitor the overall operation of the lamp, ballast, and flasher. Because I could not.

In order to solve this problem, there was another apparatus for collecting streetlight failure information by using power line communication. However, the streetlight apparatus and power line cannot block high frequency noise caused by the lighting of the street lamp. There is a problem that affects other loads sharing noise, and the error of loss of monitoring data is frequently lost, maintenance is inconvenient by wires, and the distance of power line communication is short. There was no problem.

Technical problem of the present invention created to solve this problem is as follows.
