To provide a signal controller capable of preventing synchronization deviation of time information set through an operation unit from a central device, and a traffic control system having the same.SOLUTION: A signal controller according to an embodiment of the present invention includes an internal clock, a signal generator, an operation unit, and an update unit. The internal clock counts internal time by the millisecond. The signal generator generates a control signal for controlling a signal light device in synchronization with a positive second of the internal time. The operation unit accepts input operation of time setting by the second. The update unit is configured to be able to update hours, minutes, seconds of the internal time to a set time without changing the setting by the millisecond based on the input operation of the time setting.SELECTED DRAWING: Figure 3
【課題】操作部を介して設定された時刻情報の中央装置との同期ずれを防止することができる信号制御装置およびこれを備えた交通制御システムを提供する。【解決手段】本発明の一形態に係る信号制御装置は、内部時計と、信号生成部と、操作部と、更新部とを具備する。前記内部時計は、ミリ秒単位で内部時刻を計時する。前記信号生成部は、前記内部時刻の正秒に同期して信号灯器を制御するための制御信号を生成する。前記操作部は、秒単位での時刻設定の入力操作を受け付ける。前記更新部は、前記時刻設定の入力操作に基づき、前記ミリ秒単位を変更することなく前記内部時刻の時分秒を設定時刻に更新可能に構成される。【選択図】図3
