费额显示器功能结构优化探索

Optimization Exploration Functional Structure of Charge Display

费额显示器是公路收费系统用来显示车型、收费金额的设备。鉴于各收费站需求的不同,在交通部有关标准的前提下,有必要对费额显示器功能结构优化进行探索,将费额显示器的控制单元、数码管光亮度控制单元、双路语音控制单元设计成一体化模块,以适应各种类型费额显示器快速组装的需要。

The charge display is an equipment in the highway charge system that displays auto type and passing expense. With the different demands of each toll station, it is essential to explore the optimization of functional structure of charge display at the prerequisite of concerning standards issued by Ministry of Transport of the People＇s Republic of China. In the end an integrated module including control unit, electronic tube control unit for lightness, and double sound control unit is worked out to adapt fast packing for many kinds of charge displays.
