Abstract

The utility model discloses a piano humidity automatic controller, which comprises a singlechip, a heating dehumidifier, a humidity sensor and a digital display. The heating dehumidifier, the humiditysensor and the digital display are respectively electrically connected with the singlechip. The piano humidity automatic controller can automatically monitor, control and display the humidity value inside the piano.

Description

Piano humidity self-actuated controller

Technical field

The utility model relates to a kind of humidity conditioner, is specifically related to a kind of piano humidity self-actuated controller.

Background technology

Piano inside mainly is made up of bright metal spare, string, wooden movement, refining felt etc., and the humidity in the piano has very big influence to the sensitivity of piano, tonequality etc.If humidity is excessive, then not only influences its playing effect, and reduce its serviceable life.Especially be subjected to the influence of geographical environment and seasonal climate more obvious.At present, generally can an exsiccator be installed in the inside of piano, under the bigger situation of ambient humidity, the mode energized by manual socket makes this exsiccator work dehumidifying.The mode of conventional manual dehumidifying need dehumidify by people's sense organ or experience, and not only operation comparatively bothers, and humidity control is accurate inadequately, also can not reach specific effect on moisture extraction because the time of judging dehumidifying is too short sometimes.

The utility model content

The purpose of this utility model is at the deficiencies in the prior art, and a kind of simple in structure, the piano humidity self-actuated controller that can control the piano interior humidity automatically and humidity value is shown is provided.

For achieving the above object, the utility model adopts following technical scheme: a kind of piano humidity self-actuated controller, comprise a single-chip microcomputer, heating dehumidifier, a humidity sensor and a digital indicator, described heating dehumidifier, this humidity sensor and digital indicator electrically connect with this single-chip microcomputer respectively.

Further, above-mentioned single-chip microcomputer is the ATmage48 single-chip microcomputer, with setting program testing environment humidity, the work of control heating dehumidifier.

The utility model can carry out auto-real-time monitoring, controls and demonstrate piano humidity inside value to the piano humidity inside by adopting said structure.

Description of drawings

Fig. 1 is the circuit block diagram of the utility model piano humidity self-actuated controller better embodiment.

Embodiment

See also Fig. 1, it is the circuit block diagram of piano humidity self-actuated controller better embodiment described in the utility model.This piano humidity self-actuated controller 100 comprises a single-chip microcomputer 11, a humidity sensor 12, a heating dehumidifier 13 and a digital indicator 14.Wherein, this humidity sensor 12, this heating dehumidifier 13 and this digital indicator 14 electrically connect with this single-chip microcomputer 11 respectively.Wherein, this single-chip microcomputer 11 is the ATmage48 single-chip microcomputer.This single-chip microcomputer 11, humidity sensor 12, heating dehumidifier 13 are separately positioned under the piano in the door-plate, and this digital indicator 14 is arranged under the piano door-plate and directly checks for the user outward.

The workflow of this piano humidity self-actuated controller below is described:

At first import a programmed instruction in this single-chip microcomputer 11, it comprises that the humidity range of control is 50%RH-70%RH, and control accuracy is ± 2%RH.This humidity sensor 12 records this piano humidity inside value A, and this single-chip microcomputer 11 is done contrast with the humidity range of control value of this humidity value A and this setting.As humidity value A during greater than 70%RH, this single-chip microcomputer 11 starts this heating dehumidifier 13 dehumidifying; As humidity value A during less than 50%RH, this single-chip microcomputer cuts off the power supply of this heating dehumidifier 13; When humidity value A is between the 50%RH-70%RH time, this heating dehumidifier is in energized but the state of the work of not generating heat.These humidity sensor 12 measured moisture signals all will be understood and pass through this digital indicator 14 and show in real time by this single-chip microcomputer 11.

This piano humidity self-actuated controller works in 220V alternating voltage, 50Hz frequency of operation state.Its output contact electric current is 3A.

With respect to prior art, the utility model electrically connects the mode that cooperates by single-chip microcomputer and humidity sensor with the heating dehumidifier of dehumidifying, realized the real-time follow-up of piano interior humidity and control accurately, piano inside is started automatically or cut-out heating dehumidifier power supply in desirable humidity range, and, make things convenient for the user directly to check understanding by the simple and clear current humidity value of demonstration of digital indicator.

The utility model is not limited to above-mentioned embodiment, if various changes of the present utility model or distortion are not broken away from spirit and scope of the present utility model, if these changes and distortion belong within claim of the present utility model and the equivalent technologies scope, then the utility model also is intended to comprise these changes and distortion.
