Abstract
The utility model belongs to a data identification device, in particular to an electronic pen which can lead a projector and a computer to interact. The ultrasonic wave interactive electronic whiteboard sign pen comprises a pressure drive switch, an infrared transmitting circuit, an ultrasonic wave generating circuit, a battery boosted circuit and a soft touch switch, wherein the soft touch switch is connected with the pressure drive switch, and a pen point of an electronic pen is connected with the pressure drive switch, and a microcomputer is connected with the infrared transmitting circuit and the ultrasonic wave generating circuit. The ultrasonic wave interactive electronic whiteboard sign pen is characterized by further comprising a function push button and a microcomputer with various coding, wherein the function push button is connected with the microcomputer. The ultrasonic wave interactive electronic whiteboard sign pen has the advantages that a ship-shaped drive switch arranged on an electronic pen casing is clicked, thereby triggering the corresponding function push button, and the color and the blackboard eraser function of the electronic pen can be changed at any time when in use.
Description
Technical field
The invention belongs to data identification means, especially belong to the electronic pen that projection device and computer inter are moved.
Background technology
Infrared ray and ultrasonic type interactive electronic white board can move the ultrasonic interactive electronic white board sign pen on the plate face coordinate, by catching infrared signal and ultrasonic signal, carry out after the computing, convert the coordinate of the mouse on the computing machine to, pass to computing machine by data line, the change mouse position shows by display devices such as projection device, displays by its operation of following electronic pen, accomplishes human-computer interaction.Its principle of work is: utilize ultrasound wave and infrared signal to calculate the position of electronic pen on the plate face, the aerial velocity of propagation of infrared signal is fast more a lot of than ultrasonic propagation velocity, write the zone at electronic pen, the time of Infrared Transmission can ignore, with the benchmark of infrared signal as the ultrasonic transmission time, determine the travel-time of ultrasound wave in electronic pen is write the zone, and then the distance of definite electronic pen and infrared remote receiver ultrasonic receiver, after how much parsing computings, finally obtained the coordinate of electronic pen in the blank zone, this coordinate conversion is become the coordinate of mouse, make the mouse servo-actuated in electronic pen.
The structure principle chart of existing ultrasonic interactive electronic white board sign pen as shown in Figure 1, power to total system by the battery booster circuit, it and ultrasonic output circuit, infrared transmitter, microcomputer joins, its course of work is: touch pressure transmission switch 1 when the electronic pen nib is write on blank, then drive touch-switch 6 work signal is passed to microcomputer 7, microcomputer 7 control ultrasonic output circuits 3, infrared transmitter 2 sends coherent signal and drives mouse performance, there is following defective in electronic pen at present: the coded program of the inside micro computing machine of the electronic pen of different colours is fixed, the coding that infrared is gone out is single, therefore every pen is fixing color, and the blank receiving system is to distinguish color according to the coding difference, electronic pen in writing if will change the color of demonstration and use the blackboard eraser function, use different colours pen or blackboard eraser, cumbersome.
Summary of the invention
The utility model purpose is to provide the electronic pen of a kind of infrared ray and ultrasonic type interactive electronic white board, and single pen just can be realized the replacing of written handwriting color and the switching of blackboard eraser and electronic writing pen.
The technical scheme that the utility model adopted is the ultrasonic interactive electronic white board sign pen, comprise pressure transmission switch, infrared transmitter, ultrasonic output circuit, battery booster circuit, touch-switch, touch-switch links to each other with pressure transmission switch, the electronic pen nib links to each other with pressure transmission switch, microcomputer links to each other with infrared transmitter, ultrasonic output circuit, its main points are that it also has function button and the microcomputer with multiple coding, and function button links to each other with microcomputer.
As further improving and replenishing to technique scheme, the utility model adopts following technical measures: two function buttons are arranged, one switches color, one switches blackboard eraser, one hull type transmission switch is arranged on the electronic pen housing, and its below has two fore-sets relative with the function button that switches color, switching blackboard eraser respectively.
Provide the voltage of 1.5V by No. 7 batteries of single-unit, by booster circuit voltage is risen to 6V, for electronic pen provides power supply.
Advantage of the present utility model is to click the hull type transmission switch on the electronic pen housing, thereby touch the function corresponding button, in use can change electronic pen color and blackboard eraser function thereof at any time, adopt No. 7 batteries of single-unit, be convenient for changing, more economical in the use.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail
As Fig. 2, shown in Figure 3, the ultrasonic interactive electronic white board sign pen, comprise pressure transmission switch 1, infrared transmitter 2, ultrasonic output circuit 3, battery booster circuit 4, touch-switch 6, function button 5 and microcomputer 7 with multiple coding, touch-switch 6 links to each other with pressure transmission switch 1, electronic pen nib 8 links to each other with pressure transmission switch 1, function button 5 links to each other with microcomputer 7, microcomputer 7 and infrared transmitter 2, ultrasonic output circuit 3 links to each other, and control infrared transmitter 2, ultrasonic output circuit 3 sends coherent signal and drives mouse performance.In order to dwindle the size of electronic pen, the electronic pen of infrared ray and ultrasonic type interactive electronic white board adopts No. 7 powered battery of single-unit, through the power supply booster circuit voltage is risen to 6V, for electronic pen provides power supply, power supply booster circuit and infrared transmitter 2, ultrasonic output circuit 3, microcomputer 7 join, and are the entire circuit power supply.Have 5, one of two function buttons to switch color, one switches blackboard eraser, and a hull type transmission switch 9 is arranged on the electronic pen housing, and its below has two fore-sets 10 relative with the function button 5 that switches color, switching blackboard eraser respectively.
When the electronic pen nib is touched hold-down plate surface and is write, touch pressure transmission switch 1, then drive touch-switch 6 work signal is passed to microcomputer 7, after microcomputer 7 carries out voltage sample, obtain the information that pen begins to write, the color change-over switch of function of initializing button 5, and the state value of function button 5 blackboard eraser change-over switches, and be kept in the register of microcomputer, when pressing function button 5 color change-over switches, 7 pairs of number of times of pressing of microcomputer are counted, and 7 pairs numerical value of microcomputer are encoded, and the coding back is launched coded message by infrared transmitter.At this moment, infrared receiving device in the blank receives after the infra-red code information, the processor of receiving trap obtains the corresponding code of a colouring information after coding is decoded, and the colouring information code is uploaded to blank software by driver, and trigger blank software and carry out the replacing of a colouring information, reached and changed the function that electronic pen is write color.Same principle can realize the switching that lettering pen and pen are wiped.
Protection domain of the present utility model is not limited to the foregoing description, and all technology contents identical with the technical solution of the utility model or that be equal to fall in its protection domain.
