Abstract

The utility model provides an electronic blackboard, which can synchronously display handwritings of teachers and comprises a frame for supporting, a display arranged on the frame and a circuit module for controlling the electronic blackboard to work. The electronic blackboard is characterized in that the circuit module comprises a micro-processor for computing control, a display driving module for driving the display to work, a communication module for communicating with a personal computer (PC) and a power supplying module. The display driving module and the communication module are connected with the micro-processor. The electronic blackboard adopts the display capable of communicating with a computer, realizes the function of synchronous display of the handwritings of the teachers on the electronic blackboard, effectively avoids pollution caused by chalk powders and light reflection of the existing blackboards, and greatly facilitates teaching and learning of students.

Description

A kind of electronic blackboard

Technical field

The utility model relates to a kind of electronic blackboard, in particular, relates in particular to the electronic blackboard that shows synchronously of writing a kind of and teacher.

Background technology

Along with multimedia technology progressively enter the classroom, increasing teacher is progressively adopting multimedia teaching, this and traditional blackboard traditional instruction have very big difference.For lower student, be very disadvantageous, the one, the student does not catch up with teacher's teaching, and the 2nd, the student can not imitate teacher's calligraphy, is difficult to make the student to learn teacher's handwriting skills, and is very unfavorable to student's study.If use existing blackboard, to write by chalk, the chalk powder of being trickled down all is a kind of injury to teacher and classmate.

Summary of the invention

The utility model has overcome the shortcoming of above-mentioned technical matters, and the electronic blackboard that shows synchronously of writing a kind of and teacher is provided.

For achieving the above object, the utility model has adopted following technical scheme:

Electronic blackboard of the present utility model, the circuit module that comprises passive framework, is arranged at the display on the framework and controls electronic blackboard work, it is characterized in that: described circuit module has comprised communication module and the supply module that used microcontroller, the display driver module that is used for driving display work, the realization of computing control communicated by letter with PC, and described display driver module all is connected with microcontroller with communication module.In the process of using, should guarantee that display is connected with PC by communication port, like this, teacher is by writing on PC, and its content written just can show by display.The progress of teacher's teaching is not very fast just like this, and lower student also can get caught up in, and greatly facilitates classmates' study.

Electronic blackboard of the present utility model, described framework are provided with the power interface that connects power module and power supply port; Described framework is provided with the communication interface that connects communication module and PC.Power interface is used to realize being connected of electronic blackboard of the present utility model and commercial power interface, and it is more convenient to use; Communication interface is used to realize communicating by letter of electronic blackboard and computing machine.

Electronic blackboard of the present utility model, described microcontroller are connected with and are used to carry out the storer that data are preserved; Described microcontroller is a single-chip microcomputer.Storer can be realized the storage to configuration information and corresponding data, more convenient the use.

The beneficial effects of the utility model are: the utility model is by being provided with the display that can computing machine intercoms mutually, realized the function of writing synchronous demonstration of content displayed and teacher on the electronic blackboard, and avoided pollution that chalk powder brings and the reflecting effect that existing blackboard caused effectively, greatly facilitate teaching and classmates' study.
