But, the technical issues that need to address are now, because teaching or speaker need the interactive of necessity, teacher or speaker may away from the display areas of computer, the control computer brought thus or the phenomenon of operating computer inconvenience, can control flexibly or operate, having become affects teachers ' teaching quality height or speaker and to give a lecture one of the key factor of effect quality.
Utility model content
The utility model a kind ofly realizes the TV card that infrared signal turns touch screen signal, adopts remote controller signal to turn the mode of touch-screen control signal, its objective is to efficiently control computer, improve ease-to-operate.
For realizing above-mentioned target, the utility model have employed following technical scheme:
The utility model is a kind ofly realize the TV card that infrared signal turns touch signal: comprise television master control plate module, touch screen module and external equipment;
Infrared receiver, television master control chip unit, level conversion integrated circuit unit, universal serial port socket unit is provided with in described television master control plate module;
Described touch screen module is provided with the one chip microcomputer controlling touch-screen;
Described external equipment is the computer of band OPS interface;
Described television master control plate module is connected with touch screen module by serial port data line, and touch screen module is connected with the host computer with OPS interface in external equipment by OPS signal transmssion line.
Preferably, described television master control plate module is connected with touch screen module by the external serial port data line of universal serial port socket unit.
Preferably, described infrared receiver receives remote controller infrared, infrared signal is converted into pulse wave signal and is sent to television master control chip unit by infrared receiver, and pulse wave signal is converted to the output of low pressure rs 232 serial interface signal, after level conversion integrated circuit unit receives low pressure rs 232 serial interface signal, convert standard serial port signal to and transfer to touch-screen by universal serial port socket unit, touch-screen then by Signal transmissions to main frame, complete the transformation of infrared signal to touch signal.
The beneficial effects of the utility model:
1. provide and a kind of traditional infrared transmission mode is converted into touch control mode, realize teacher or speaker's remote control computer;
2. traditional tv is combined with computer and forms all-in-one, in use do not need to take other resources such as computer USB port.
Accompanying drawing explanation
To be that the utility model is a kind of realize the television board logic diagram that infrared signal turns touch screen signal to Fig. 1.
Wherein, television master control plate module 1, infrared receiver 11, television master control chip unit 12, level conversion integrated circuit unit 13, universal serial port socket unit 14; Touch-screen 2; External equipment 3.
Embodiment
In order to better the utility model is described, be now described further by reference to the accompanying drawings.
As shown in Figure 1, the utility model is a kind ofly realize the television board that infrared signal turns touch screen signal, relates to television board main control module 1, touch screen module 2 and external equipment 3.
Difference installation infrared receiving element 11, television master control chip unit 12, level conversion integrated circuit unit 13, universal serial port socket unit 14 in television master control plate module 1; Connection between infrared receiver 11, television master control chip unit 12, level conversion integrated circuit unit 13 and universal serial port socket unit 14 and the transmission of signal are the transmission being realized connection and signal by the PCB in television board.
Wherein, infrared receiver 11 is infrared receiving terminal, and this infrared receiving terminal comprises infrared detection diode, amplifier, amplitude limiter, band pass filter, integrating circuit, comparator etc.;
Television master control chip unit 12 comprises television master control chip, for pulse wave signal being converted to the coordinate signal of touch-screen, in addition, and this whole television board of television master control chip major control and for connecting external equipment 3;
Level conversion integrated circuit unit 13 is level conversion IC, for converting low pressure rs 232 serial interface signal to standard serial port signal;
TV plate master control borad module 1 outside is also provided with touch screen module 2, touch screen module 2 inside is provided with the one chip microcomputer (English name: Micro Controller Unit controlling touch-screen, be called for short: MCU), the MCU of touch-screen converts the coordinate signal received to computer OPS signal, and by OPS data line transfer to external equipment 3; Television master control plate module 1 of the present utility model realizes the connection with touch screen module 15 by universal serial port socket unit 14, adopts RS232 interface to connect with serial mode.
In addition, the television master control plate module 1 of television board is also connected with external equipment 13, and external equipment 3 is the computer of band OPS interface.
By the combination of television master control plate module 1, touch screen module 2 and external equipment 3, infrared signal can be realized and turn touch screen signal.
This infrared receiver 11 connects the television master control chip unit 12 in television master control plate module 1, when infrared receiver 11 receives the infrared signal that speaker or teacher trigger remote controller and send, infrared signal can be passed through amplification and become pulse wave signal with amplitude limiting processing and transfer to television master control chip unit 12 by the infrared receiving terminal of infrared receiver 11, television master control chip unit 12 is by pulse wave signal converted coordinate signal, and form the output of standard serial port signal by level conversion integrated circuit unit 13, touch screen module 2 is transferred to through universal serial port socket 14, coordinate signal is converted to computer OPS signal by the MCU in touch screen module 2, and the computer of external equipment 3 is transferred to by OPS holding wire, thus realize infrared signal and convert touch screen signal to.
