Traffic signal pattern display method and device

The invention is a traffic signal pattern displaying method and device relating to traffic control system, in the traffic signal control displayed by the illuminant diode array, uses sequence to control the lighting of the illuminant diode, reflects the activation character of the traffic signal pattern; according to the character of the traffic signal pattern, it is divided into several character parts, the illuminant diode in each character part is controlled with group sequence to alternate the bright spots, the invention includes signal light main body and signal control unit, the signal control unit has a center controller, power model and driving model. The signal control unit also includes sequence control model, the sequence control model issues control command to the driving model through the center controller, driving model control the bright state of diode according to the instructions; the signal control unit also includes programmable storing model; the signal control unit has a communication interface interacting with the outer information, the invention can display traffic signal pattern dynamically. 一种涉及交通控制系统的交通信号图案显示方法和装置，在发光二极管阵列显示的交通信号控制中，对于构成交通信号图案中的发光二极管采用时序控制点亮，反映交通信号图案的活动特征；根据交通信号图案的特征，分为若干特征部，对各特征部中的发光二极管进行分组时序控制交替点亮，本发明包括信号灯主体和信号控制单元，信号控制单元中具有中央控制器、电源模块和驱动模块，其特征在于：所述的信号控制单元还包括时序控制模块，所述的时序控制模块通过中央控制器向驱动模块发布时序控制指令，驱动模块根据指令控制相应的发光二极管的点亮状态；信号控制单元还具有可编程存储模块；信号控制单元具有与外部信息交换的通讯接口，本发明能动态地显示交通信号图案。
