Embodiment 1

[0041] see figure 1 , figure 2 and image 3 , the noise cancellation control device 7 proposed in this embodiment includes: a reflector 6, a motor 4, a noise cancellation processor 3, a connection mechanism 5, an external controller 1 and a receiver 2, and here, the motor 4 and the receiver 2 are all It is connected with the noise canceling processor 3 , the external controller 1 is connected with the receiver 2 , and the motor 4 is also connected with the reflector 6 through the connecting mechanism 5 . On the basis of the above connection, the receiver 2 is used to receive the control signal sent by the external controller 1, and send the received control signal to the noise canceling processor 3, the noise canceling processor 3 is a microcontroller, specifically by the The microcontroller receives the control signal through the I / O port, and the noise elimination processor 3 converts the received control signal into a rotation signal, specifically a pulse width modulatio...

Embodiment 2

[0055] see Figure 4 , the present embodiment provides a noise reduction control system comprising: a pressure swing adsorption device 8 and the above-mentioned noise reduction control device 7, a noise reduction control device 7 is provided at the gas outlet of the pressure swing adsorption device 8, and the noise reduction control device 7 is used for Used in conjunction with the pressure swing adsorption device 8, the oxygen flow at the gas outlet merges with the oxygen flow reflected by the reflector 6 to form a vortex.

[0056] Here, the shape of the air outlet is set to be a trumpet shape. Because the oxygen flow is the airflow ejected from the gas outlet by the action of air pressure, the shape of the gas outlet is very important to whether the oxygen flow will cause noise. When the shape of the gas outlet is a common circular hole, the oxygen flow will generate a larger noise when flowing through the gas outlet. In this embodiment, the shape of the air outlet is set ...

Abstract

The invention provides a de-noising control device and system and relates to the technical field of process control. The de-noising control device comprises a reflecting plate, a motor, a de-noising processor, a connecting mechanism, an external controller and a receiver, wherein the motor and the receiver are both connected with the de-noising processor; the motor is connected with the reflecting plate through the connecting mechanism; and the external controller is connected with the receiver. When a control signal sent by the external controller is received by the receiver, the control signal is sent to the de-noising processor for processing; the de-noising processor is used for converting the received control signal into a rotating signal and then sending the rotating signal to the motor; after the rotating signal is received by the motor, the reflecting plate is driven to rotate; and under the rotating effect of the reflecting plate, oxygen gas flowing out of an air outlet is resisted against the oxygen gas reflected by the reflecting plate, so that the noise at the air outlet can be effectively reduced.

Description

technical field [0001] The invention relates to the field of process control, in particular to a noise elimination control device and system. Background technique [0002] Oxygen is thin in the plateau environment, and the partial pressure of oxygen in the air decreases, which leads to a corresponding decrease in the oxygen inhaled by the human body, resulting in hypoxia in the body and triggering altitude sickness, such as shortness of breath, headache, dizziness, and vomiting. Moreover, the extremely hypoxic environment on the plateau can cause a variety of plateau diseases, such as dyspnea, diarrhea, and confusion. [0003] In order to improve people's livelihood, in recent years, pressure swing adsorption devices have been gradually adopted to improve the oxygen partial pressure in anoxic environment, so as to make the oxygen enrichment in the environment meet the needs of human body. Pressure Swing Adsorption (PSA), referred to as PSA, is a new type of gas adsorption s...
