It can be expressed by LED with different specifications and models.

光学自动控制系统可由人工干预电源开关或计算机软件操纵，显示信息一部分操纵由计算机内存程序流程进行，并根据中间继电器等功放机电子器件键入显示信息模块。

The optical automatic control system can be operated by manual intervention power switch or computer software. Part of the display information is operated by the computer memory program flow, and the display information module is input according to the intermediate relay and other power amplifier electronic devices.
           

2.智能语音系统简易智能语音系统可由录音磁带设备进行。高规定状况下，智能语音系统选用编程语言设计方案视频语音程序流程，运用可读写光碟、光盘驱动器、功放和音箱，在运动控制系统下进行检索及播发工作中。

2. Intelligent voice system simple intelligent voice system can be carried out by recording tape equipment. Under the condition of high regulation, the intelligent voice system uses programming language to design the video voice program flow, and uses the read-write CD-ROM, CD-ROM drive, power amplifier and speaker to search and broadcast under the motion control system.

3.操纵方法提出分手控、遥控器2种，手控选用一般电源开关或手控控制面板来操纵。手控控制面板设备选用塑料薄膜触压式电源开关，可安裝在表层或盘体侧边，安裝在侧边可选用索道开展弹放运输。遥控器方法为红外线作用是进行除开关电源外的所有手控作用，遥控器间距不超出8m。

3. There are two kinds of control methods: separate control and remote control. The general power switch or manual control panel is used for manual control. The manual control panel equipment adopts the plastic film touch pressure power switch, which can be installed on the surface layer or the side of the panel body, and the cableway can be used to carry out the elastic release transportation. The remote control method is infrared function, which is used for all manual control functions except switching power supply. The distance between remote controllers shall not exceed 8m.
