Description

A kind of piano guidance system

Technical field

The utility model relates to a kind of piano utility appliance, relates in particular to a kind of piano guidance system.

Background technology

Piano owing to have good comprehensive performance and widely purposes be called as the king of musical instrument, play for auxiliary, some piano utility appliance have appearred on the market, guiding user piano is bent, yet, existing piano utility appliance generally all needs the professional person that piano is reequiped, and the user uses very inconvenient.

The utility model content

For the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of piano guidance system, and it does not need piano is reequiped, and is very easy to use.

The utility model adopts following technical scheme for achieving the above object:

A kind of piano guidance system comprises:

The first single-chip microcomputer;

The optics trigger sensor that equates with the piano key number, it is installed in respectively on the key of piano and with the first single-chip microcomputer and is connected, and is used for startup, stop or the done state of record key, and is transferred to the first single-chip microcomputer and produces corresponding supplied with digital signal;

First communication module, it is connected with the first single-chip microcomputer, is used for supplied with digital signal is sent to second communication module and output digit signals is sent to the first single-chip microcomputer;

Second communication module is used for supplied with digital signal is sent to second singlechip and output digit signals is sent to first communication module;

Second singlechip, it is connected with second communication module, for the treatment of supplied with digital signal, produces output digit signals;

With the LED that the piano key number equates, it is installed in respectively on the key of piano and with the first single-chip microcomputer and is connected, and processes output digit signals by the first single-chip microcomputer, and LED is luminous in control.

Wherein, further comprise display, this display is connected with second singlechip, is used for showing successively being beneficial to the required note of playing the user and being pressed into accurately key.

Preferably, described first communication module is connected with second communication module by wireless signal.

Preferably, described first communication module is connected with second communication module by data line.

A kind of piano guidance system that the utility model is set forth, its beneficial effect is: the utility model does not need piano is reequiped, and during use, only needs optics trigger sensor and LED are installed on the key, do not affect the use of key, greatly improved convenience; And, record the state of key by adopting the optics trigger sensor, give information for subsequent treatment, LED can be indicated flexibly according to user's the situation of playing, rather than according to intrinsic order; In addition, show successively the required note of playing by display, more be beneficial to the user and be pressed into accurately key.

Description of reference numerals:

10, the first single-chip microcomputer; 20, optics trigger sensor; 30, first communication module; 40, second communication module; 50, second singlechip; 60, LED; 70, display.

Embodiment

Come the utility model is further described below in conjunction with accompanying drawing and specific embodiment.

Please refer to shown in Figure 1, it has demonstrated the concrete structure of the utility model preferred embodiment, a kind of piano guidance system comprises the first single-chip microcomputer 10, optics trigger sensor 20, first communication module 30, second communication module 40, second singlechip 50 and LED60, wherein:

Described optics trigger sensor 20 equates with the piano key number, it is installed in respectively on the key of piano and with the first single-chip microcomputer 10 and is connected, the startup, stop or the done state that are used for the record key, and be transferred to the corresponding supplied with digital signal of the first single-chip microcomputer 10 generations, for subsequent treatment is given information.

Described first communication module 30 is connected with the first single-chip microcomputer 10, is used for supplied with digital signal is sent to second communication module 40 and output digit signals is sent to the first single-chip microcomputer 10.

Described second communication module 40 is used for supplied with digital signal is sent to second singlechip 50 and output digit signals is sent to first communication module 30.

Described second singlechip 50 is connected with second communication module 40, for the treatment of supplied with digital signal, produces output digit signals.

Described LED60 equates with the piano key number, and it is installed in respectively on the key of piano and with the first single-chip microcomputer 10 and is connected, and processes output digit signals by the first single-chip microcomputer 10, and LED60 is luminous in control.

Embodiment of the present utility model also can comprise display 70, and this display 70 is connected with second singlechip 50, is used for showing successively being pressed into accurately key thereby further be beneficial to the user by the required note of playing.
