Abstract

A contain infrared ray touch-control formula handwriting pad, constitute by touch-control board, USB or serial ports, microcontroller, infrared subassembly, wherein, infrared subassembly passes through the bus with microcontroller and links to each other. When the touch control type handwriting pad is in wireless data communication with a handheld portable device mobile phone or a PDA, the obvious obstacles that the touch control type handwriting pad in the prior art needs to buy an infrared communication system matched with the handheld device of the user and the like independently are overcome, the communication port of a PC (personal computer) is not occupied any more, the purchase cost performance of the consumer is improved, and the touch control type handwriting pad is very convenient to use.

Description

With infrared touch tablet

The utility model relates to a handwriting board, in particular to a touch type handwriting board combined with infrared rays.

At present, one of the main purposes of handheld portable devices, such as mobile phones and PDAs, is to manage address books, and use the address books on them to communicate with each other, send emails, send short messages, etc. But because these hand-held portable devices volume all has the trend that becomes smaller and smaller, the keyboard on it is also difficult to use because of the restriction of volume, therefore will input address book on it very inconvenient. But, as shown in Figure 1, the existing touch-sensitive tablet 10 on the market comprises touch panel 11, control button 12, USB or serial port 14, microcontroller 15, when it carries out wireless data communication with these hand-held portable devices At the same time, there are obvious obstacles, and the infrared communication system that is matched with the handheld device must be purchased separately, which not only takes up many communication ports of the PC, reduces the cost performance of consumers, and is extremely inconvenient to use.

The purpose of this utility model is to solve the above inconvenience and provide a handwriting mode, which can be conveniently combined with the address book of the hand-held portable device.

In order to achieve the above purpose, the utility model 10 is composed of a touch panel 11, a communication interface 14, a microcontroller 15, and an infrared component 16, wherein the control button 12 is optional, and the infrared component 16 is connected to the microcontroller 15 through a bus.

The utility model integrates handwriting recognition technology and infrared communication technology in one, adopts the standard IrDA infrared communication protocol, can communicate with most handheld devices on the market, greatly facilitates use, and can connect users on the PC The input made is transmitted to the corresponding place of the hand-held device (such as memorandum, calendar, etc.).

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Fig. 1 is the hardware architecture diagram of existing touch-sensitive tablet;

Fig. 2 is a hardware architecture diagram of the present utility model;

Fig. 3 is the system operation flowchart that the utility model uses.

10 touch tablet;

11 touch panel; 12 control buttons; 13 personal computer PC;

14 communication interface; 15 microcontroller; 16 infrared component;

17 mobile phone or PDA;

As shown in Figure 2, the model of each part in the preferred embodiment of the utility model is: touch panel 11: 59-031-02000; microcontroller 15: 9950PP010-b31; infrared component 16: EL XXXXX; communication interface 14 is USB or serial port.

As shown in Figure 3, the system operating procedure that the utility model uses is as follows:

1. The touch panel (Touch Panel) 11 is an inductive touch component. The user first writes on it with a finger or a hard pen, and the electronic simulation of its two-dimensional (x, y) or three-dimensional (x, y, z) coordinates After the signal will be converted into a digital signal, it will enter the microcontroller (Micro controller) 15;

2. Microcontroller 15 transmits digital signals containing two-dimensional or three-dimensional coordinate information to personal computer PC 13 through USB or serial port 14. This moment, the software on the personal computer PC 13 automatically recognizes the coordinate information as text information. Therefore, the user can input various characters very naturally by handwriting on the utility model. These utilize handwritten characters, can utilize the software on the personal computer PC 13 to do moderate editing;

3, 4, 5. The personal computer PC 13 is transmitted to the infrared component (IrDA component) 16 with the assistance of the microcontroller 15, and then transmitted to the mobile phone or PDA 17 through infrared rays, as a short message, calendar, address book , work or notes, etc. input data;

The control button 12 in Fig. 2 is to do the usefulness of technical expansion, such as: the initiation of control communication, the button goes online etc., and it is optional component in the utility model. In addition, the software on the personal computer PC 13 can also read the information on the mobile phone or the PDA by the utility model, that is, the infrared assembly on the utility model can be used as the management channel of the PC to the mobile phone or the PDA.

Of course, the communication interface 14 can be a USB port, a serial port, or a parallel port, or even the very popular Bluetooth; in addition, the infrared component 16 can be integrated inside the microcontroller 15, which can save space.
