本实用新型涉及医疗仪器的领域，更具体地，涉及一种可用于采集声音数据的智能充放气静音控制盒。The utility model relates to the field of medical instruments, in particular to an intelligent inflation and deflation mute control box which can be used for collecting sound data.
背景技术Background technique
声音是由物体振动产生的声波，是通过介质（空气或固体、液体）传播并能被人或动物听觉器官所感知的波动现象。声音以波的形式振动（震动）传播，可以通过任何物质传播形成的运动。Sound is a sound wave produced by the vibration of an object. It is a wave phenomenon that propagates through a medium (air or solid, liquid) and can be perceived by the auditory organs of humans or animals. Sound travels in the form of vibrations (vibrations) in the form of waves, which can travel through any material in motion.
物体在一秒钟之内振动的次数叫做频率，单位是赫兹，字母Hz。人的耳朵可以听到20Hz-----20KHz的声音，最敏感是1KHz-----3KHz之间的声音。The number of times an object vibrates within one second is called frequency, and the unit is hertz, the letter Hz. The human ear can hear the sound from 20Hz to 20KHz, and the most sensitive is the sound from 1KHz to 3KHz.
噪声的反映表现是声音，凡是妨碍人们正常休息、学习和工作的声音，以及对人们要听的声音产生干扰的声音，都可以称为噪声。噪声按声音的频率可分为：<400Hz的低频噪声、400～1000Hz的中频噪声及>1000Hz的高频噪声。The reflection of noise is sound. Any sound that hinders people's normal rest, study and work, and that interferes with the sound that people want to listen to can be called noise. According to the frequency of the sound, the noise can be divided into: low-frequency noise <400Hz, medium-frequency noise between 400-1000Hz and high-frequency noise >1000Hz.
根据中华人民共和国GB3096-93《城市区域环境噪声标准》，疗养区、高级别墅区、高级宾馆区等特别需要安静的区域夜间噪声标准值应低于40dB，以居住、文教机关为主的区域夜间噪声标准值应低于45dB。According to the People's Republic of China GB3096-93 "Environmental Noise Standards for Urban Areas", the noise standard value at night in areas that need to be quiet, such as sanatorium areas, high-end villa areas, and high-end hotel areas, should be lower than 40dB. The noise standard value should be lower than 45dB.
然而目前市场上存在的以气泵驱动的充放气床垫工作时噪音较大，影响夜间安静的睡眠环境。However, the air pump-driven inflatable and deflated air mattresses currently on the market are noisy when they work, which affects the quiet sleeping environment at night.
减弱噪音主要通过以下3种方式进行：1）在声源处减弱噪音。2）在传播途径中减弱噪音。3）在人耳处减弱噪音。由于人耳处减弱噪音通常会影响用户的舒适度，故本发明主要通过减弱声源及切断传播途径两种方式进行。Noise reduction is mainly carried out in the following three ways: 1) Noise reduction at the sound source. 2) Reduce noise in the transmission path. 3) Attenuate noise at the human ear. Since reducing the noise at the human ear usually affects the comfort of the user, the present invention mainly performs two methods of reducing the sound source and cutting off the transmission path.

由于声音衰减的原因主要为：①当声波从声源向四面八方辐射时，波前的面积随传播距离的增加而不断扩大，声波被扩散，通过单位面积上的声能相应减少；②由于传播媒质的粘滞性、热传导和分子驰豫过程等原因，声波被吸收，这两点均使声波在传播过程中声能不断地被转化为其他形式的能量，从而导致声强不断衰减。因此，可以知道声音在传播中要不断地被衰减，离声源近，声音能量大；离声源远，声音能量小。The main reasons for sound attenuation are: ① When the sound wave radiates from the sound source to all directions, the area of the wave front expands with the increase of the propagation distance, the sound wave is diffused, and the sound energy passing through the unit area decreases accordingly; ② Due to the propagation medium Due to the viscosity, heat conduction and molecular relaxation process, the sound wave is absorbed. Both of these two points make the sound energy continuously converted into other forms of energy during the propagation of the sound wave, resulting in continuous attenuation of the sound intensity. Therefore, it can be known that the sound is constantly attenuated during transmission, and the sound energy is large if it is close to the sound source; the sound energy is small if it is far away from the sound source.
由于采用分体化设计，声音采集器可以尽可能靠近声源处，由于靠近声源，所以可以得到更加清晰的鼾声素材，便于分析计算。Due to the split design, the sound collector can be as close to the sound source as possible. Because it is close to the sound source, clearer snoring material can be obtained, which is convenient for analysis and calculation.
充气泵、排气泵本身采用特制的静音气泵，从声源处减小噪声。气泵的噪声主要来自2个方面：1）电机做功时产生。2）空气与管壁摩擦时产生。静音气泵从这两方面入手，本身材质采用更为优良的静音隔音材质，减小噪声的产生。The air pump and exhaust pump themselves adopt special silent air pumps to reduce noise from the sound source. The noise of the air pump mainly comes from two aspects: 1) It is generated when the motor does work. 2) Produced when air rubs against the pipe wall. The silent air pump starts from these two aspects, and its material is made of more excellent silent and sound-proof material to reduce the generation of noise.
同时，系统采用PWM技术控制泵的速率，进一步减小由于电机做功时产生的噪声。PWM，即脉冲宽度调制，是对逆变电路开关器件的通断进行控制，使输出端得到一系列幅值相等的脉冲，用这些脉冲来代替正弦波或所需要的波形。也就是在输出波形的半个周期中产生多个脉冲，使各脉冲的等值电压为正弦波形，所获得的输出平滑且低次谐波少。按一定的规则对各脉冲的宽度进行调制，即可改变逆变电路输出电压的大小，也可改变输出频率。At the same time, the system uses PWM technology to control the speed of the pump to further reduce the noise generated when the motor does work. PWM, that is, pulse width modulation, is to control the on-off of the switching device of the inverter circuit, so that the output terminal obtains a series of pulses with equal amplitudes, and these pulses are used to replace the sine wave or the required waveform. That is, multiple pulses are generated in half a cycle of the output waveform, so that the equivalent voltage of each pulse is a sinusoidal waveform, and the obtained output is smooth and has few low-order harmonics. By modulating the width of each pulse according to certain rules, the output voltage of the inverter circuit can be changed, and the output frequency can also be changed.
其次，由于声音采集器与控制盒采用分体化设计，所以可以将控制盒放置在距离人耳更远的位置，从而使噪音在空气传播过程中进行衰减，减小人耳所感知到的设备工作噪音。Secondly, since the sound collector and the control box adopt a split design, the control box can be placed farther away from the human ear, so that the noise can be attenuated during the air transmission process, and the equipment perceived by the human ear can be reduced. Working noise.
