Because many netizens can't grasp the key points of sand table model making, Huaye model will briefly introduce the basic requirements of landform sand table. Firstly, with its good practicability, sand table model is widely used in the field of urban planning and design, showing the planning blueprint, as well as in many fields such as environmental governance, engineering transformation, agricultural planning, real estate design and so on. Used to display its characteristics. Different models have different characteristics and different materials. Different models are suitable for different situations. Sand table model is an expression of the system, process, thing or concept studied. It can also refer to samples made according to experiments, drawings, enlargement or reduction. These samples are usually used for exhibition, testing or casting mechanical parts, etc.

1.控制方式分手控、遙控2種，手動控制用普通開關或手控面板進行控制。手控面板裝置采用薄膜觸控開關，可安裝在閥體表面或側面，安裝在側面可采用滑道進行釋放輸送。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 membrane touch switch, which can be installed on the surface or side of the valve body, and can be released and transported by slideway. Infrared remote control means to complete all manual control functions except power supply, and the remote control distance shall not exceed 8m.
2.光電顯示內容，形成路燈、關鍵區域范圍線等，采用光纖作為發光器件，射燈作為光源，光源顏色區分內容。專題元素可以用不同規格的發光二極管來表示。光電控制系統可由手動控制開關或計算機系統控制，顯示部分由計算機存儲器程序控制，并通過固態繼電器等功放元器件輸入顯示單元。
2. Photoelectric display content, forming street lamps, range lines of key areas, etc., using optical fiber as light-emitting device, spotlight as light source, and light source color to distinguish content. Thematic elements can be represented by light-emitting diodes 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構和鋁合金結構。盤面高度小于1米，視場角度約為20度-30度。目前外包裝結構越來越豪華，可根據用戶要求設計外包裝類型，其基本要求是外包裝應與閥體協調，外觀美觀大方。
3. At present, there are two kinds of wood structure and aluminum alloy structure in the mold base and outer packaging. The disk height is less than 1m, and the field of view angle is about 20 ° - 30 °. At present, the outer packaging structure is becoming more and more luxurious. The outer packaging type can be designed according to the user's requirements. Its basic requirement is that the outer packaging should be coordinated with the valve body and have a beautiful and generous appearance.
4.語音系統簡單的語音系統可以通過錄音裝置來完成。在高要求的情況下，語音系統使用計算機語言設計語音程序，使用光盤、光盤驅動器、功率放大器和揚聲器在計算機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 programs, and uses optical discs, optical disc drives, power amplifiers and speakers to complete the search and playback under the control of the computer.
