由于許多網(wǎng)民無法掌握沙盤模型制作的沙盤要點(diǎn)，所以視野模型，對地形地貌沙盤的基本要求將作簡要介紹。

Because many netizens can't grasp the key points of the sand table model, the basic requirements of the visual field model and the landform sand table will be briefly introduced.

1、控制方式分手控、遙控2種，手動(dòng)控制用普通開關(guān)或手控面板進(jìn)行控制。手控面板裝置采用薄膜觸控開關(guān)，可安裝在閥體表面或側(cè)面，安裝在側(cè)面可采用滑道進(jìn)行釋放輸送。紅外遙控方式是指完成除電源外的所有手控功能，遙控距離不超過8m。

1. There are two control modes: remote control and remote control. Manual control is controlled by ordinary switch or manual control panel. The manual control panel device adopts the membrane touch switch, which can be installed on the surface or side of the valve body, and the slide way can be used to release and transport when it is installed on the side. Infrared remote control means to complete all the manual control functions except power supply, and the remote control distance is not more than 8m.

2、光電顯示內(nèi)容，形成路燈、關(guān)鍵區(qū)域范圍線等，采用光纖作為發(fā)光器件，射燈作為光源，光源顏色區(qū)分內(nèi)容。專題元素可以用不同規(guī)格的發(fā)光二極管來表示。光電控制系統(tǒng)可由手動(dòng)控制開關(guān)或計(jì)算機(jī)系統(tǒng)控制，顯示部分由計(jì)算機(jī)存儲(chǔ)器程序控制，并通過固態(tài)繼電器等功放元器件輸入顯示單元。

2. Photoelectric display content, forming streetlights, key area line, etc., using optical fiber as light-emitting device, spotlight as light source, light source color to distinguish content. Thematic elements can be represented by LEDs of different specifications. The photoelectric control system can be controlled by manual control switch or computer system. The display part is controlled by computer memory program and input into the display unit through power amplifier components such as solid state relay.
                 

3、目前在模架和外包裝中有兩種木結(jié)構(gòu)和鋁合金結(jié)構(gòu)。盤面高度小于1米，視場角度約為20度-30度。目前外包裝結(jié)構(gòu)越來越豪華，可根據(jù)用戶要求設(shè)計(jì)外包裝類型，其基本要求是外包裝應(yīng)與閥體協(xié)調(diào)，外觀美觀大方。

3. At present, there are two kinds of wood structure and aluminum alloy structure in mold base and outer packaging. The height of the disk is less than 1 meter, and the field of view is about 20-30 degrees. At present, the structure of the outer package is more and more luxurious. The type of the outer package can be designed according to the user's requirements. The basic requirement is that the outer package should be coordinated with the valve body and have a beautiful appearance.

4、語音系統(tǒng)簡單的語音系統(tǒng)可以通過錄音裝置來完成。在高要求的情況下，語音系統(tǒng)使用計(jì)算機(jī)語言設(shè)計(jì)語音程序，使用光盤、光盤驅(qū)動(dòng)器、功率放大器和揚(yáng)聲器在計(jì)算機(jī)控制下完成搜索和播放工作。

4. Voice system simple voice system can be completed by recording device. In the case of high requirements, the voice system uses computer language to design voice program, and uses CD, CD driver, power amplifier and loudspeaker to complete the search and play work under the control of computer.
