Embodiment 1
[0056] The plug-in financial POS voice prompter of this embodiment is a device that is independent of the POS terminal, can operate independently, and completes this function by collecting relevant data of the POS terminal. In the communication with the POS terminal It can be wired or wireless.
[0057] The hardware of the plug-in financial POS voice prompter of the present embodiment consists of a power supply circuit, a communication interface circuit, a microcontroller circuit, a voice storage and playback circuit, an audio amplifier circuit and a loudspeaker, a repeat broadcast button, a prompt selection switch, a volume switch, etc. components.
[0058] The power circuit provides a stable power supply for the whole circuit, which can be composed of a switching regulator chip or a linear regulator chip and some peripheral devices (capacitors, inductors, etc.), and its input is a separate power adapter or obtained from a financial POS terminal. The stable voltage should be...
Embodiment 2
[0074] This embodiment is basically the same as Embodiment 1, except that the hardware of the plug-in financial POS voice prompter of this embodiment is more optimized, and the software is more concise.
[0075] The hardware of the plug-in financial POS voice prompter of this embodiment is composed of components such as a communication interface circuit, a microcontroller circuit, a voice storage and playback circuit, an audio amplifier circuit, and a loudspeaker. The hardware block diagram is shown in Figure 3.
[0076] The software of the plug-in financial POS voice prompter in this embodiment is composed of communication data reception, voice broadcast data recognition, voice chip control code generation, voice playback and other parts.
[0077] The first step is to check whether there is data on the communication port, and if so, receive the data packet from the financial POS terminal, and calculate whether the verification value is correct, and discard it if it is not cor...
Embodiment 3
[0081] The built-in financial POS voice prompter of this embodiment is a kind of prompter that embeds the device into each component of the POS terminal and can realize all functions.
[0082] The hardware of the built-in financial POS voice prompter of this embodiment is composed of financial POS terminal microcontroller circuit, voice storage and playback circuit, audio amplifier circuit and loudspeaker, financial POS terminal keyboard, volume switch and other components. The financial POS terminal keyboard is an existing circuit of the financial POS terminal, which can be used for repeat broadcasting and prompt selection functions, and can even control the volume.
[0083] The financial POS terminal microcontroller circuit is an existing circuit of the financial POS terminal, which controls the operation of the entire POS terminal software and hardware, and the voice broadcast program can be added on the basis of the original software.
[0084] The voice storage and playbac...
