Control device for sand table car model

Abstract

The invention relates to a control device for a sand table car model. The control device comprises a magnetic element, a magnetic induction element, a signal collecting circuit, a central processing unit, an infrared transmitter, an infrared receiver, a comparator and a controller. The magnetic induction element is stimulated by the magnetic element to generate electric signals; the magnetic induction element induces a magnetic field and generates the electric signals; the signal collecting circuit collects the electric signals; the central processing unit receives the electric signals and recognizes the position of a car model robot; the infrared transmitter transmits infrared light to the car model robot to provide a travelling route; the infrared receiver receives infrared light signals; the comparator receives and compares the infrared light signals and outputs corresponding level signals; the controller is used for receiving the level signals and controlling the car model robot to travel. The magnetic induction element is used for generating current signals under the magnetic field of the magnetic element to recognize the position of the car model robot, and the magnetic induction element is compact in structure, so that high-accuracy positioning is achieved, and the requirement for the position of a sand table is met; on the other hand, the car model robot is controlled to travel through the infrared transmitter and the infrared receiver and used for demonstration of the sand table, interaction between people and the sand table is achieved, and the sand table car model is more interesting.

Description

technical field [0001] The invention relates to the field of sand table demonstration, and more specifically relates to a sand table car model control device. Background technique [0002] In the prior art, sand tables are used in various industries such as training, real estate, and military affairs. The sand table is roughly divided into two types, one is represented by a refined model, and the other is represented by a simple model to represent related buildings, and then equipped with digital projections that can change colors and patterns to enhance the overall environment. Both of the above two sand table forms use multimedia such as lighting, sound, and large-screen background information introductions as additional forms of expression for the sand table. The above two sand table forms have the following disadvantages: [0003] 1. Can only show the whole picture of the model in real scene; [0004] 2. Although the lighting system is gorgeous, it is used to set off ...

AI Technical Summary

Problems solved by technology

[0003] 1. Can only show the whole picture of the model in real scene;

[0004] 2. Although the lighting system is gorgeous, it is used to set off the atmosphere of the exhibition hall;

[0005] 3. Although there are moving car models in the sand table, they can only be on fixed tracks and lack changes;

[0006] 4. Most sand tables cannot be used for business demonstrations;

[0007] 5. For the sand table projected by digital, there is nothing to attract the audience except for the gorgeous lighting and sound effects;

[0008] 6. The large-screen display is limited to the introduction of background information, and cannot interact with the sand table
