Abstract

The utility model relates to a receiving reading pen, comprising a receiving coil, a signal processing module and a communication interface which are successively in electric connection, and also comprising an image decoding module and an image sensor which are successively in electric connection with the communication interface; the image sensor and the receiving coil are arranged on a nib part of the receiving reading pen. The receiving reading pen of the utility model is realized in combination with a talking machine through the ingenious cooperation of the image identification and positioning processing techniques and is meanwhile suitable for common books and books printed with OID (Object Identifier) optical codes or other two dimension codes; the receiving reading pen does not need extra switches, works stably and reliably and has low costs.

Description

A kind of reception talking pen

Technical field

The utility model relates to the education electronic product, is specifically related to a kind of applied widely, working stability and the low reception talking pen of cost.

Background technology

Object identity (Object Identifier; Abbreviation OID) the optical recognized point-reading pen is made up of optics camera, demoder, central processing unit, acoustic processing and demonstration five parts; Through the OID light sign indicating number on the optical sensor scanning book; Pass through decoder decode and central processing unit intelligent navigation again, the literal of putting, image are play.OID receives the talking pen product on the market at present, all concentrates on all components and parts on the one-pen, causes the stature of pen bigger and heavier, and sound tonequality can not get guaranteeing, is unfavorable for the popularization on a large scale of product.The common talking pen of point reader can't be discerned OID light sign indicating number or other two-dimension codes simultaneously, makes that like this both can't be compatible, is unfavorable for that children learn to use.

The utility model content

The utility model technical issues that need to address are, how a kind of reception talking pen is provided, and can be applicable to common books simultaneously and be printed on the books of OID light sign indicating number or other two-dimension codes, and not influence use.

The technical matters of the utility model solves like this: make up a kind of reception talking pen, comprise the receiving coil, signal processing module and the communication interface that are electrically connected successively, also comprise the image decoding module and the imageing sensor that are electrically connected successively with said communication interface; Said imageing sensor and receiving coil all are arranged on the written position that receives talking pen.

According to the talking pen that the utility model provides, said signal processing module comprises signal receiving unit, buffering amplifying unit, filter unit, gain control and amplifying unit, rectification and filter unit and the buffering amplification output unit that is electrically connected successively.

According to the talking pen that the utility model provides, also comprise the power module that is electrically connected with said signal processing module, image decoding module and imageing sensor.

The reception talking pen that the utility model provides, with the supporting use of point reader, compare prior art and have following advantage:

1, is applicable to common books and be printed on the books of OID light sign indicating number or other two-dimension codes simultaneously;

2, no snap switch utilizes decoding to lose efficacy and controls, working stability, reliable.

Description of drawings

Further the utility model is elaborated below in conjunction with accompanying drawing and specific embodiment:

Fig. 1 is that the utility model receives the talking pen circuit block diagram.

Embodiment

As shown in Figure 1; The reception talking pen of the utility model specific embodiment; Comprise the receiving coil, signal processing module and the communication interface that are electrically connected successively, also comprise the image decoding module and the imageing sensor that are electrically connected successively with said communication interface, and power module; Said imageing sensor and receiving coil all are arranged on the written position (convenient like this use and accurate positioning) that receives talking pen, composing images sensor assembly; Said signal processing module comprises signal receiving unit, buffering amplifying unit, filter unit, gain control and amplifying unit, rectification and filter unit and the buffering amplification output unit that is electrically connected successively.

This receives talking pen and the such cooperating of point reader:

To certain distance, imageing sensor starts talking pen near books, and point reader transmits simultaneously; Receive processing through talking pen and confirm that by processor click location (triggers the click location of point reader through the startup of imageing sensor; This moment, imageing sensor was equivalent to a microswitch), in this process, the coordinate signal of priority processing picture decoder output; Have only the image decoding failure, just handle the corresponding data of talking pen coordinate of processor identification itself.The advantage of design is to click response soon like this.A kind of in addition scheme also can just be controlled the point reader emission after picture decoder lost efficacy, click low-response like this.

Certainly, the above only is the preferred embodiment of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and flow process change or modify, includes in the utility model patent claim is.

Claims

1. one kind receives talking pen, comprises the receiving coil, signal processing module and the communication interface that are electrically connected successively, it is characterized in that, also comprises the image decoding module and the imageing sensor that are electrically connected successively with said communication interface; Said imageing sensor and receiving coil all are arranged on the written position that receives talking pen.

2. according to the said talking pen of claim 1; It is characterized in that said signal processing module comprises signal receiving unit, buffering amplifying unit, filter unit, gain control and amplifying unit, rectification and filter unit and the buffering amplification output unit that is electrically connected successively.

3. according to the said talking pen of claim 1, it is characterized in that, also comprise the power module that is electrically connected with said signal processing module, image decoding module and imageing sensor.
