Embodiment
For the purpose of this utility model, technical scheme and advantage is more clearly understood, with reference to embodiment and accompanying drawing,
The utility model is described in further detail, and exemplary embodiment of the present utility model and its explanation are only used for explaining this
Utility model, it is not intended as to restriction of the present utility model.
Embodiment 1
In the present embodiment, a kind of convenient tax-control cash register, including control unit, memory cell, input block, display list
Member, communication unit, tax control unit, payment unit and print unit, described control unit and memory cell, input block, display
Unit, communication unit, tax control unit, payment unit and print unit electrically connect and control its work.
Existing input block generally use keyboard or touch-screen, user is by keyboard or touch-screen to tax-control cash register
Input the operational orders such as gathering, printed invoice.As shown in figure 1, Fig. 1 is the input block knot that the utility model embodiment 1 provides
Structure block diagram.Input block described in the present embodiment includes acquisition module, amplification module, voice module, single-chip microcomputer, switch module, multiple
Position module, clock module and power module, user are entered the operating instructions by voice to tax-control cash register.
The acquisition module electrically connects with amplification module, specifically using electret microphone, is sent out user using electret microphone
The voice signal gone out is converted into electric signal, and by corresponding electric signal output to amplification module.
The amplification module electrically connects with voice module, and specifically using triode, the electric signal that electret microphone is sent passes through
Triode is amplified.The essence of signal amplification is exactly to realize the conversion of energy, is controlled with a less input signal of energy
Another energy is made, makes that the big signal of energy comparison can be obtained in the load of its output end.The object of amplification is variable quantity, is put
Big premise is that transmission is undistorted, therefore the electric signal that the present embodiment is sent using triode to electret microphone is amplified, described
Triode emission knot positively biased, collector junction are reverse-biased.
The voice module and monolithic mechatronics, specifically use LD3320 chips, the process of speech recognition mainly includes
Two stages, training stage and cognitive phase, the training stage trains voice several times by acquisition module input, by pretreatment
