Abstract
The utility model relates to a keyboard instrument plays man -machine interactive installation, it includes bottom plate and key, its characterized in that: being equipped with the bottom plate lining strip on the bottom plate, being equipped with distance sensor and PIC singlechip on the bottom plate lining strip, distance sensor is located the below of key, be equipped with the display window in the inner end of key, be equipped with LED pilot lamp and USB interface on the display window, the PIC singlechip passes through the circuit and is connected with distance sensor, LED pilot lamp and USB interface and external power supply, the key has 88, and the below of every key respectively is equipped with a distance sensor, and 22 adjacent distance sensor constitute a set ofly, totally four organize, and every combination is passed through plug -in components and is connected in an organic whole with two PIC singlechips, eight PIC singlechips, the LED pilot lamp also has 88, and the LED pilot lamp is located the inner end of key, distance sensor is infrared inductor spare or electromagnetism inductor spare. The artificial indication that this device utilized electron device to replace mr has improved the assurance degree of playing accuracy and rhythm to the student, has improved the quality of instruction.
Description
Technical field
The utility model is a kind of information collection apparatus on keyboard instrument key, particularly
Human-computer interaction device played by a kind of keyboard instrument.
Background technology
Organ, accordion and piano are all keyboard kind musical instruments.For piano, it is by pressing key, affects the gavel that enclose carpet inside piano, then knocks steel wire string and sounds.Playing of piano, requires high to accuracy and rhythm, the accuracy of student's piano and rhythm, is indication by teacher and under metronomic cooperation, just can has good assurance.But different teachers is not quite similar for accuracy and rhythmic power of a test, and result can cause sensation at a loss as to what to do to student, and then has influence on quality of instruction.
Key is all mounted on base plate, and in the process of playing, the distance between key and base plate can change, and the situation of this change is directly related with the accuracy of playing and rhythm.The change of distance can be detected by range sensor, as long as the information of detected distance change can be observed, student just can hold the accuracy and rhythm of oneself playing very well, but existing piano does not all have efficiency configure sensor, and this is the shortcoming of existing piano.
Summary of the invention
The purpose of this utility model is to overcome existing piano playing with teacher's indication for the main defect affecting quality of instruction, invents a kind ofly to detect by distance the keyboard instrument that accurate acquisition plays information and play human-computer interaction device.
The purpose of this utility model realizes as follows: human-computer interaction device played by described keyboard instrument, comprise base plate and key, it is characterized in that: on base plate, be provided with base plate lead-in, base plate lead-in is provided with range sensor and PIC single chip microcomputer, and range sensor is positioned at the below of key; Be provided with display window in the inner end of key, display window is provided with LED light and USB interface; PIC single chip microcomputer is connected with range sensor, LED light and USB interface and external power supply by circuit.
Described key has 88, and the below of each key is respectively provided with a range sensor, and 22 adjacent range sensors form one group, totally four groups, often combination two PIC single chip microcomputer, and eight PIC single chip microcomputer are connected in one by plug-in unit; LED light also has 88, and LED light is positioned at the inner end of key.
Described range sensor is infrared induction device or electromagnetic induction device.
Good effect of the present utility model is as follows: the utility model utilizes electron device to substitute the artificial indication of teacher, plays accuracy and rhythmic power of a test, improve quality of instruction so substantially increase to student.

Embodiment
As shown in Fig. 1 Fig. 3 Fig. 4, human-computer interaction device played by described keyboard instrument, comprises base plate 1 and key 2, it is characterized in that: on base plate 1, be provided with base plate lead-in 3, base plate lead-in 3 is provided with range sensor 4 and PIC single chip microcomputer 5, and range sensor 4 is positioned at the below of key 2; Be provided with display window 6 in the inner end of key 2, display window 6 is provided with LED light 7 and USB interface 8; PIC single chip microcomputer 5 is connected with range sensor 4, LED light 7 and USB interface 8 and external power supply by circuit.
As shown in Figure 2, described key 2 has 88, and the below of each key 2 is respectively provided with a range sensor 4, and 22 adjacent range sensors 4 form one group, totally four groups, and often combination is connected in one by plug-in unit by two PIC single chip microcomputer, 5, eight PIC single chip microcomputer 5; LED light 7 also has 88, and LED light 7 is positioned at the inner end of key 2.
Described range sensor 4 is infrared induction device or electromagnetic induction device.
During use, when key is pressed and discharge, the range sensor of key and below can occur apart from upper change, and change into change in voltage by range sensor, this voltage carries out digital collection and analysis by PIC single chip microcomputer, and show that real-time key plays information, this information passes to student by the flicker of LED light, made student very clear oneself play state, improve quality of instruction.
The utility model can be connected with computer by USB interface, realize carrying out parameter configuration, hardware detection and data analysis on computers.
