Zusammenfassung: | In a method for controlling a streetlight according to the present invention, each of a plurality of node streetlights may detect the existence or absence of an object, and may transmit and receive a signal to/from other node streetlights through short-range wireless communication, whereby a dimming value of each node streetlight is controlled according to an object existence signal and a lighting area activation signal. Therefore, lighting of streetlights can be more promptly and efficiently controlled. Even without an object existence signal due to absence of an object in a detection area of any one of node streetlights, a dimming value of the node streetlight is controlled according to a previously input lighting area activation signal, thus making it possible to safely light the front area of an object before the object approaches, which is advantageous. Also, a node streetlight having detected an object transmits a live lighting area activation signal to a live lighting streetlight which needs to be immediately lit, and also transmits a virtual lighting area activation signal in advance to a virtual lighting streetlight disposed subsequent to the live lighting streetlight in order to control the virtual lighting streetlight to be automatically lit after a set time, whereby node streetlights disposed in the forward direction can be normally lit although an abnormal problem occurs later on, for example, when a motion detect sensor does not detect the object or communication problem occurs.
Dans un procédé de commande d'un lampadaire public selon la présente invention, chacun d'une pluralité de lampadaires publics nodaux pourra détecter la présence ou l'absence d'un objet et pourra émettre/recevoir un signal à destination/en provenance d'autres lampadaires publics nodaux au moyen d'une communication sans fil à courte portée, de manière à commander une valeur de gradation de chaque lampadaire public nodal selon un signal de présence d'objet et un signal d'activation de zone d'éclairage. L'invention permet donc d'assurer une commande plus rapide et efficace de l'éclairage de lampadaires publics. Sans signal de présence d'objet du fait de l'absence d'un objet dans une zone de détection de l'un quelconque des lampadaires publics nodaux, il est néanmoins possible de commander une valeur de gradation du lampadaire public nodal selon un signal d'activation de zone d'éclairage précédemment entré et donc d'éclairer en toute sécurité, de manière avantageuse, la zo |
