A piano tuning detection device and an implementation method thereof relate to the technical field of piano tuning, and in particular, to a device and a method for detecting a string frequency in the process of tuning a piano, which solves the technical problem that the professional requirement is high, the tuning precision is poor, and the operation is inconvenient in the existing piano tuning work. The tuning detection method comprises the following steps: a. sticking a laser recognition sticker on a string to be detected; b. illuminating the laser recognition sticker with a light ray from a laser head; c. pressing a key corresponding to the string to be detected; d. providing a detection signal source to a central processing unit to detect an actual frequency value of the string; and e. performing comparison. The piano tuning operation is implemented according to the principle that the laser head reads a disc in a driver without requiring a special auditory sense of a tuning person. The piano tuning operation can be accomplished by a common operator, so the operation is convenient and the tuning precision is high. |
