摘　　要：本文阐述一种基于DCC控制协议的模型列车控制用DCC信号发生器,该信号发生器主要由CPU模块和功率放大模块等几部分组成。该信号发生器产生的DCC信号可以控制市面上常见的基于DCC协议的模型列车的运动控制和音效管理,亦可控制符合该协议的外围设备的动作,如信号机点灯控制、道岔的转换控制等,相比现有的市场上的模型列车控制器而言,该发生器具有电路结构简单,价格低廉,预留二次开发端口,可用于开发轨道交通专业列车运行控制沙盘等教学设备的开发,也可以用于列车模型控制的二次开发。This article describes a DCC signal generator for model train control based on the DCC control protocol. The signal generator is mainly composed of a CPU module and a power amplification module. The DCC signal generated by the signal generator can control the motion control and sound effect management of common model trains based on the DCC protocol on the market, and can also control the actions of peripheral devices that comply with the protocol, such as signal generator lighting control, switching control of switches, etc. Compared with the existing model train controllers on the market, the generator has a simple circuit structure and a low price, and reserves secondary development ports. It can be used to develop railroad professional train operation control sand tables and other teaching equipment. It can also be used for secondary development of train model control.
