The working principle and the working process of the invention are as follows: when the system works, an instruction triggering module in the electric control multi-module urban sand table is used as a preprocessing end to call physical attributes and position coordinates of the sand table according to an instruction corresponding strategy and generate a corresponding data set, then the data set is sent to an execution module through bottom layer communication, position coordinate information and the sand table physical attributes are associated through analysis matching rules, the sand table model area where the sand table model area is located and the type of the sand table in the sand table model area are obtained through judgment, corresponding display output instructions are output, wherein the display output instructions comprise a light mode, an acoustic effect mode and an environmental light mode, the acoustic effect mode and the environmental light mode in the sand table model area are selected through a computer terminal, the computer terminal can perform custom setting and modification on the display output instructions, a sand table outline graph is synchronously generated according to position coordinates, RGB color information of a light source in the sand table outline graph and a light source in a corresponding area is stored in the computer terminal, and the light source corresponding to the sand table model area is driven by a light controller to light on the light source corresponding area, thereby realizing display of different scenes and meeting the display requirements of different scenes.

When geographic information is displayed, in addition to height information display, color information display is required to be added in cooperation with the sand table for vividly displaying different types of sand tables, light display is carried out by arranging LEDs, traditional LED light control is carried out by utilizing analog dimming, analog control utilizes generation, amplification, transformation and delay analog signal means, and real-time adjustment control is carried out by taking voltage, current or electromagnetism and other physical quantities which take any values as control variables. However, analog dimming is easily limited by signal interference when receiving analog signals, and in addition, a control circuit is often complex and cannot meet market requirements, so that the invention adopts a double-network-port network card signal DM9003 for network transmission control, specifically, as shown in FIG. 3, an LED display screen control panel can be compatible with an Art-Net network transmission protocol upwards and can be compatible with a DMX512 LED standard display protocol downwards, a processor control unit receives data sent by a computer terminal through a network port after receiving the data, acquires a data packet according to an ID number of the processor, encapsulates other data packets according to the DMX512 network protocol and forwards the data packets to a next-level control unit, the working principle is that the computer terminal is controlled based on the architecture of the Art-Net network control protocol, control instructions and dimming data are transmitted to each processor through an Ethernet connection network port, the linked list structure of the processor is a basic unit in a network, 512 LED display lamps are hung on an RS485 bus at most, each processor should have a unique IP address, the Ethernet connection network port and the computer terminal software is used for communication upwards, and the control circuit board with the ID number is used for forwarding data sent to the next-level control circuit board after the data are continuously forwarded.

Confirm that computer terminal and light controller are connected normally, carry out function setting and selection according to the sand table model region at the operation interface at computer terminal, can light or close according to position coordinate and the lamp light source of laying on it, and then ensure the lamp source condition of every coordinate pixel, according to the different lamp light source conditions that provide of exhibition district trade attitude, every layer all is provided with the lamp light source in the building of commercial office district, the layering is lighted under the control of computer terminal, and luminance gradual change percentage is 30%, 60%, 90% are unequal, can take the gradual change mode from top to bottom, roof, building four corners and commercial roof equipartition are equipped with finished product lamp light source, dry by the reflection light again at ground wire, room corner, if: a myriad of lamplight mode, a gradual change mode, a lamplight show mode and the like.

The sand table position information database is established according to the ground objects which are reduced in equal proportion in each exhibition area, so that the commercial industry state detail characteristics of different exhibition areas are simulated and reflected more truly and intuitively, and the geographic information of the real world is restored to the maximum extent. In this embodiment, the position of an object can be calculated by adopting 3D model software through vector expression, the plane movement of a scene model is represented by vector translation, the projection in a specific direction is obtained by vector point multiplication, the current direction of the object is controlled by vector cross multiplication, the relative coordinates of the current model are represented by local position attributes, the world coordinates of the current model are represented by inherent position attributes, and the world coordinates are converted into the relative coordinates by instruction transformation.

The lamp light source is a ceiling type lamp light source or an LED lamp light source. The building exhibition district is including a plurality of plywood layers of range upon range of laying, plywood layer body colour adopts ICI paint to color, the colour is handled with the press polish corrugated surface technology, the fidelity has been ensured, the colour that selects for use than actual that the colour on the model can be done, every layer of plywood layer selects the layer effect show or passes through the show of stationary mast supporting effect through hydraulic lift, the lamp illuminant sets up to ceiling type lamp illuminant, set up every layer of plywood layer light arrangement circuit of being convenient for like this, existing evenly distributed who does benefit to inside light, also can play the effect of fixed main part to the building. A core tube is arranged at the center of the plywood layer, so that the plywood layer is convenient to connect in a line manner and meanwhile, the heat dissipation of the building lamp light source is facilitated. The landscape water system exhibition area comprises a base glass layer, a surface glass layer and optical fiber lamps, and corresponding patterns are drawn under the base glass, specifically, mosaic paint or blue-like water paint with different depths can be sprayed on the base glass layer. Base glass sets up to water wave glass, spills into emulation glue on water wave glass in order to simulate flowing water, lays the surface glass layer again, and the surface glass layer sets up to plain noodles glass, has laid blue lamp light source at waterside both sides equidistant, puts at the central point and sets up the fiber lamp according to corresponding shape, and the fiber lamp plays the leaded light effect. The optical fiber lamp has high purity, low attenuation and rich color change, can generate colorful visual effects like fantasy, and has good energy-saving effect, thereby avoiding the possible glare phenomenon. After the circular telegram for the fiber lamp, the light source that it sent can pass through the reflector and form parallel light, this parallel light itself does not have the color, the light via the color filter becomes colored light, thereby make optic fibre outwards propagate the light beam, the fiber lamp light source loss is little and can guarantee light source intensity, the fiber lamp can send the light of different colours under the cooperation of light controller, satisfy the multiple demand of actual sand table show, abundant richness and the hierarchy nature of commercial attitude of fully reappearing.

The embodiments of the present invention have been described in detail, but the present invention is only the preferred embodiments of the present invention, and is not to be considered as limiting the scope of the present invention. All equivalent changes and modifications made within the scope of the present invention should be covered by this patent.
