Abstract
The utility model provides a radio-frequency operation prompting device which comprises a radio-frequency module, a radio-frequency data reading module, a voice storage module and a power amplification module; the radio-frequency module, the radio-frequency data reading module, the voice storage module and the power amplification module are connected respectively in sequence; the radio-frequency module is used for acquiring the recognized address of labeling information; the radio-frequency data reading module is used for reading the digital voice from the voice storage module by analyzing the address information; and the digital voice is amplified through the power amplification module after digital-analog conversion for providing an automatic voice prompt.
Description
Technical field
The utility model relates to a kind of electronic equipment, especially a kind of radio frequency operation prompting device.
Background technology
In some large scale industry production places, a lot of cautions and notice board are often arranged, for staff and visit personnel provide various cautions and guidance, but traditional notice board function ratio is more single, dumb, cost is high, content update is complicated, and failing observed personnel may make troubles.
Summary of the invention
The shortcoming of above-mentioned traditional warning sign for a change, the utility model provides a kind of radio frequency operation prompting device.
The utility model comprises radio-frequency module, rf data read module, voice storage module, power amplifier module, it is characterized in that, radio-frequency module, rf data read module, voice storage module, power amplifier module connect successively, radio-frequency module obtains the identification address of label information, the rf data read module utilizes voice storage module that digital speech is pointed out from power amplifier module amplification carrying out automatic speech work after digital-to-analog conversion by analyzing address information.
The beneficial effects of the utility model are that employing wireless mode introduction is searched for automatically, and is easy to use, has good practicability and economy.
Description of drawings:
Fig. 1 is a schematic diagram of the present utility model, and Fig. 2 is the utility model electricity structural drawing.
Embodiment:
As shown in Figure 1, the utility model comprises radio-frequency module 1, rf data read module 2, voice storage module 3, power amplifier module 4, radio-frequency module 1, rf data read module 2, voice storage module 3, power amplifier module 4 connect successively, radio-frequency module 1 obtains the identification address of label information, rf data read module 2 utilizes voice storage module 3 that digital speech is carried out automatic speech work from power amplifier module 4 amplifications after digital-to-analog conversion and points out by analyzing address information.。
As shown in Figure 2, RFID read head circuit is delivered to microcontroller with the label information that obtains.Microcontroller reads the corresponding digital voice flow according to label information and converts simulated audio signal to through work of prerecording or the suggestion voice that digital-to-analog conversion will be stored in the chip from speech data memory, deliver to built-in loudspeaker or external earphone then after audio amplifier circuit amplifies.Simultaneously, LCD display shows present place, workplace according to label information.In addition, can inquire about some information on services by man-machine interface.EM4095 is a RFID base station read-write chip, the carrier wave frequency of operation is 100～150kHz, can operate a Chinese speech synthesis chip that the XF2S3011 chip is the research and development of news Fetion breath Science and Technology Ltd. of Chinese University of Science and Technology to labels such as EM400X, EM4050, EM4150, complete speech synthesis system is fully integratible into single processor inside, receives and synthesize arbitrary text by serial ports.The serial ports baud rate is 9600bps, and by the present duty (Busy/Ready) of RAD port indication speech chip.Because the sound signal power ratio of XF2S3011 chip output is less, in order to make sound signal enough power drive loudspeakers is arranged, and need carry out power amplification by the LM4871 circuit, gain amplifier can be regulated by resistance R.
