However, the above-described conventional street light and remote monitoring system of the tracks can transmit data bidirectionally between the computer 31 'of the central control center 30' and the central processing unit 20 'of the switchboard 2'. When the one-way communication with the mobile phone causes an abnormality in the streetlight holder L 'and the wire 3', the manager of the central control center 30 'can be notified by voice of the location and the failure of the streetlight through the mobile phone. In addition, in the absence of the administrator of the central control center (30 '), the status of the street lights cannot be checked or controlled in the absence of the administrator of the central control center (30'), and the manager of the central control center (30 ') checks the abnormal street lamps for on-site maintenance. Direct the personnel to the street lamp repair work through a separate communication means, and the maintenance personnel directly repair the street light and then use a separate communication means to manage the central control center (30 '). It notifies the administrator has the inconvenience, while the central processing unit (20 ') and through a data communication state of the street lamps are secured facility continues call and field repair personnel to receive them need to check the status of the lamp.
