1. a kind of timed task processing method, it is characterised in that applied to Centralized Controller, the Centralized Controller passes through electric powerLine carrier module communicates to connect with Node Controller, and the Node Controller communicates to connect with street lamp, and methods described includes:

  • The timed task data that background server issues are received, the timed task data include performing time point and task classType;

    The timed task data are used for the switch and brightness regulation of timing controlled street lamp;

    Before the execution time point, the timed task data distributing is given to the Node Controller, so as to the nodeController performs timed task corresponding to the task type at the execution time point;

    When Centralized Controller re-powers, before the timed task data that the reception background server issues, in addition to:

    Read access time and date from real-time clock RTC;

    The system time of the Centralized Controller is calibrated with the date according to the read access time from RTC;

    After read access time is calibrated with the date to the system time of the Centralized Controller from RTC described in the basis,Also include:

    According to prefixed time interval, according to the system time of background server and the base station time of operator to Centralized ControllerSystem time calibrated, and by the system time of the Centralized Controller after calibration write-in RTC.
