Abstract
The utility model discloses a voice broadcasting device for a touch screen. The voice broadcasting device comprises the touch screen and a voice broadcasting unit, wherein the voice broadcasting unit comprises an MCU (microprogrammed control unit), a power module, a TTS (text to speech) module, an audio power amplifier module and a loudspeaker; the MCU is connected with the TTS module; the TTS module is connected with the audio power amplifier module; the audio power amplifier module is connected with the loudspeaker; meanwhile, the MCU is connected with the touch screen, and communication is conducted through an MODBUS protocol. According to the device, the touch screen and the MCU are integrated, so that the phenomenon of the weak human-computer interface caused by exclusive use of the touch screen is avoided; and the integrated TTS module can broadcast current work states, alarm information and operation prompting information of the touch screen in a voice manner.
Description
Technical field
The utility model relates to speech play technical field, particularly a kind of sound broadcasting device for touch-screen.
Background technology
At present, graphic control panel is as a kind of intelligent interface that people and machine are connected as a single entity, touch-screen has powerful figure to show and data processing function, can intuitively reflect that flow process trend and the parameter of industrial control system change, and are widely used in all types of industries control field by various ways such as data, curve, figure, animations.Yet, although touch-screen can show for user provides picture and text vision clearly, after often can only finding by scene, could be reported to the police or be pointed out by outside equipment, such separation system can only just can carry out afterwards, delay processing time and easily accidents causedly cause danger.
Summary of the invention
Goal of the invention: the object of the invention is provides a kind of sound broadcasting device for touch-screen for the deficiencies in the prior art, make work at present state, warning message and the operation prompt information of touch-screen can avoid existing by scene, find after could by outside equipment report to the police or point out, such separation system can only just can carry out afterwards, stop over the processing time and easily accidents causedly cause dangerous defect.
Technical scheme: in order to realize goal of the invention, the invention discloses a kind of sound broadcasting device for touch-screen, comprise touch-screen and speech play unit, described speech play unit comprises MCU, power module, TTS voice synthetic module, audio frequency power amplifier module and loudspeaker; Described MCU is connected with TTS voice synthetic module; Described TTS voice synthetic module is connected with audio frequency power amplifier module; Described audio frequency power amplifier module is connected with loudspeaker, and described MCU is connected with touch-screen simultaneously.
Between described MCU and touch-screen, can adopt MODBUS agreement to communicate.
As preferably, for the more touch panel device of compatibility, and under same baud rate, obtain message transmission rate faster, between described MCU and touch-screen, can adopt MODBUS-RTU agreement to communicate.
As preferably, in order to make described sound broadcasting device there is stronger antijamming capability and can be connected with more R-T unit, between described MCU and touch-screen, by meeting the RS-485 interface of industrial standard, be connected.
As preferably, for good human-computer interaction interface is provided to user, described speech play unit also comprises human-computer interaction module, and described human-computer interaction module is connected with MCU.
As preferably, in order to realize visual man-machine interface and to provide operation input interface to user, described human-computer interaction module comprises picture and text display module and key-press module, and described picture and text display module is connected respectively at MCU with key-press module.
Beneficial effect: the present invention compared with prior art, described device is undertaken integrated by touch-screen and single-chip microcomputer, the man-machine interaction of having avoided independent use touch-screen to cause is weak, so just realized the sound broadcasting device of the touch-screen of integral structure, and integrated TTS voice synthetic module can be reported work at present state, warning message and the operation prompt information of touch-screen by the mode of voice.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model voice playing device;
Fig. 2 is the chip connection diagram of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, single-chip microcomputer voice system is comprised of power module, MCS51 single chip control module, RS485 level switch module, 4 * 4 key-press modules, LCD display module, TTS voice synthetic module, audio frequency power amplifier module and loudspeaker.Described MCS51 single chip control module is connected with touch-screen by RS485 level switch module, and described MCS51 single chip control module is also connected with TTS voice synthetic module, LCD display module and 4 * 4 key-press modules respectively; Described TTS voice synthetic module is connected with loudspeaker by audio frequency power amplifier module.
Below in conjunction with embodiment, the utility model is further described.
As shown in Figure 2, described MCS51 single chip control module adopts AT89C52 single-chip microcomputer, and described TTS voice synthetic module adopts XF-4240 chip, and RS485 level switch module adopts MAX485 chip.AT89C52 single-chip microcomputer is connected with it by the SPI interface of XF-4240 chip, wherein, AT89C52 single-chip microcomputer provides the SPI clock signal of communication with P37 pin, with P20 pin, control the selection enable signal of XF-4240 chip, use P21 pin to be used as the main frame output/slave input data signal of SPI interface, the audio output interface of XF-4240 chip is connected the report of carrying out audio frequency with loudspeaker by note amplifier, synthesizing of any Chinese text of XF-4240 chip support, can adopt GB2312, GBK, BIG5 and Unicode coded system, also support the synthetic of English alphabet simultaneously, its audio output interface can also regulate word speed neatly, intonation and volume, make user can hear clear melodious tonequality and coherent intonation smoothly.Because RS-485 works in semiduplex mode, so the pin P10 of AT89C52 single-chip microcomputer drives the input/output enable pin of chip to be connected with MAX485, for control chip, be operated in required I/O mode of operation.The RXD pin of AT89C52 single-chip microcomputer is connected with DI pin with the RO of MAX485 respectively with TXD pin, has realized the conversion between the RS-485 signal level of MODBUS of single-chip microcomputer Transistor-Transistor Logic level and touch-screen by MAX485 chip.
Explanation to disclosed above-described embodiment, make those skilled in the art can realize or use the utility model, the those skilled in the art of modification team to above-described embodiment are apparent, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model is not restricted to embodiment illustrated herein, but will meet the wide region consistent with principle disclosed herein and features of novelty.
