Fig. 1 shows the structured flowchart of the electronic teaching instrument of the present invention.
Detailed description of the invention
Below by drawings and Examples, technical scheme is described in further detail.
Fig. 1 shows the structured flowchart of the electronic teaching instrument of the present invention.
In one embodiment of the present of invention, it is provided that a kind of electronic teaching instrument, as it is shown in figure 1, this electronic teaching instrument bag
Include:
Model 10, is arranged on the image collecting device 20 within model 10, LED 30 and regulation LED
The actuator 40 of 30 brightness, the controller 50. being connected with image collecting device 20 and actuator 40
In the present embodiment, image collecting device 20 is for the image within collection model 10, controller 50
Image for gathering according to image collecting device 20 calculates the brightness within this model 10, and works as model
When brightness within 10 is less than the threshold value preset, control and regulation device 40 regulates the LED 30 within model 10
Brightness.
In the present embodiment, model can be building model, or other are easy to the model of observation, at model
Inside arranges image collecting device, such as video camera or photographing unit, shoots the internal scene of model, then uses
The brightness of image analyzed by controller, thus when brightness flop within model, can control to adjust device
The brightness of the internal LED of regulation model.
Further, controller 50 includes display unit, for showing the figure that image collecting device 20 gathers
Picture.
Additionally, controller 50 also includes graphics processing unit, for obtaining the image of image collecting device 20
And this image is calculated and analyzes, obtain the brightness of image.
It addition, the controller of the present embodiment can use electronic computer, personal PC machine or panel computer,
It is not particularly limited at this.
The structure of the present invention is described in detail below by way of specific embodiment.
In the present embodiment, model uses building model, and then the inside at building model arranges LED and takes the photograph
As head, and actuator uses miniature Arduino Beetle controller, and by arranging DC-DC modulus of conversion
Block and IRF540N metal-oxide-semiconductor control and regulate LED, and the LED of the present embodiment etc. can use the LED of 3W
Lamp bead, and in order to prevent the high temperature impact on model of LED, LD etc. arranges fin.
Then LED, photographic head and actuator are connected to controller, i.e. on PC, are used for being controlled
And demonstration.
In one embodiment, when being used for demonstrating opened loop control, PC inputs fixing LED
