The technical solution of the utility model is further elaborated with reference to embodiment and accompanying drawing.
A kind of keyboard instrument optical flame detector is present embodiments provided, the keyboard instrument optical flame detector includes optical flame detector body 1, should
Optical flame detector body 1 includes Photoinduction device 11 and connecting portion 12 and master control borad 6, and the bottom of connecting portion 12 is provided with photoinduction dress
11 are put, tumtum 3 is hit in the bottom of Photoinduction device 11 and upright keyboard musical instrument and hammer 4 is corresponded and set, and photoinduction fills
Put 11 and be configured with hitting tumtum 3 according to predetermined space, Photoinduction device 11 is provided with 88, and each Photoinduction device altogether
11 can carry out the movement of certain spacing on connecting portion 12, and change that so can be preferably to each key 2 is felt
Should, each detection unit can be made to recorded music data by optoelectronic induction detection, it is ensured that sensing accurate and do not do mutually
Disturb.In addition, the optical flame detector is additionally provided with master control borad 6, master control borad 6 electrically connects with the optical flame detector body 1, for controlling optical flame detector sheet
The circuit system of body 1.
The keyboard instrument optical flame detector is additionally provided with support 5, and optical flame detector body 1 is fixedly installed by the support 5 of top both sides
In the interior case of keyboard instrument, as at the top of piano, two supports 5 are fixedly installed on case in piano for example, by the device of screw respectively
The both sides at top, the keyboard instrument optical flame detector use concealed design, are suspended on two walls of qin case, do not destroy keyboard instrument,
Key space will not be taken, one can be formed with keyboard instrument, it is easy for installation, it will not be influenceed by external environment, also will not
Have influence on the user of keyboard instrument.
The optical flame detector, which not only may be mounted in piano, enters row information identification and collection, can also be placed on other keyboards
In kind musical instrument, such as pipe organ, accordion, the collection of music information can be carried out using the inductor.
88 Photoinduction devices 11 and 88 piano keys 2 have one-to-one relation, when key 2 acts, hit
Tumtum 3 and hammer 4 can produce motion therewith, and 88 Photoinduction devices 11 can produce motion with the motion for hitting tumtum 3,
Photosignal will also change with the change in location for hitting tumtum 3 and hammer 4, and the photosignal has also just reacted the action of key
The information of rhythm, responsiveness and pressing dynamics, in addition when if during using other keyboard kind musical instruments, Photoinduction device 11
Particular number can be adjusted correspondingly according to the hitting tumtum 3 and hammer 4 of different keyboard instruments.
Wherein specifically, the vertical range for hitting tumtum 3 of the Photoinduction device 11 and upright keyboard musical instrument is 1-20 centimetres,
The predetermined space set as 1-20 centimetres, Photoinduction device 11 can corresponding to sense that each hits tumtum 3 and hammer 4
Action message, the distance that specific Photoinduction device 11 can sense hammer 4 are 3 cms, and most precisely distance is 1 centimetre of left side
The right side, overall adjustable extent are 12 centimetres, and Photoinduction device 11 could be arranged to 1 centimetre with piano struck string device vertical range,
Under the distance, Photoinduction device 11 can be very good to sense each the action change for hitting tumtum 3 and hammer 4, set so
Distance, optical flame detector body 1 do not interfere with yet keyboard instrument construction and keyboard instrument user, using keyboard instrument optical flame detector
Identification keyboard instrument hits the principle of the action of tumtum 3, can produce signal more accurate, and collectable signal is extensive, such as will
The scale of performance, note, rhythm interval, play dynamics, duration and loudness of a sound data acquisition into master control borad 6, obtain level letter
Number.In addition be within 20 centimetres of predetermined space preferably by, according to different optical sensors and different musical instruments it is specific in
Portion's bulk, is adjusted accordingly to gap size.
Specifically, the optical flame detector body 1 can be infrared inductor laser inductor either other ray classes
Induction installation, wherein infrared inductor are inductively measured using the physical property of infrared ray.Laser inductor is then logical
Transmitting laser pulse is crossed, reflects all directions scattering light by hitting tumtum 3 and hammer 4, some scattered light returns to sensor and connect
Device is received, so as to recorded the action message for hitting tumtum 3 and hammer 4, recorded the music information of the transmission of keyboard instrument keyboard 2.
The step of this keyboard instrument optical flame detector signal output is that photoinduction body 1 hits the action of tumtum 3 by identification first
Information gathering is to data-signal, and the data-signal is 5V level signal, the data-signal that then will be received by master control borad 6
Data file is converted into, wherein specifically can see by Fig. 3, the level signal passes through 11 in master control borad 6
SN4HC595D single-chip microcomputers are controlled, and the SN4HC595D single-chip microcomputers are a kind of IC chip, 11 SN4HC595D
Single-chip microcomputer and 88 piano keys 2 are corresponded and set, and each SN4HC595D single-chip microcomputers control 8 keys, are received in photoreceptor
Data file is converted into real time by the master control borad 6 after to 5V level signals, the data file is specifically MIDI data file,
Next as can be seen from Figure 4, the MIDI data file collected is converted into USBMIDI by P89C52X2BA single-chip microcomputers, then passes through
USB interface is connected to mobile terminal or computer end, or by P89C52X2BA single-chip microcomputers midi signal without
