The disclosure is related to a wind field system, and more particularly to a full covered wind outlet device and a matrix wind generation system using the same.
Coronavirus disease 2019 (abbreviated as, COVID-19) is one of the most fatal epidemics in human history, and it has infected more than 100 million people. Similar to cold virus, COVID-19 is a kind of disease transmitted through the respiratory tract, so it is an epidemic likely causing large-scale infection.
The large-scale global spread of COVID-19 has caused to major problems such as the strict control of global infectious diseases, the collapse of the medical system, and the impact of the economic system. Because of responsibility for treating COVID-19 patients, the medical system has become the most important place for infectious disease control. Therefore, due to the high infectiousness of the COVID-19, it is a priority to allocate COVID-19 patients in the negative pressure ward to prevent the virus in the ward from spreading to other places outside the ward. In addition, the medical workers who have contact with COVID-19 patient also must wear protective clothing to prevent from being infected.
However, the ward with negative pressure, the standard dressing procedure and disinfection procedure of protective clothing are still impossible to absolutely prevent the medical workers from being infected during the treatment of COVID-19 patients. For example, the cluster infection caused by the COVID-19 No. 812 patient in the Taoyuan Hospital, Ministry of Health and Welfare is that the doctor was infected during the diagnosis and treatment of patient. Therefore, there is a considerable room for improvement in the existing infectious disease control mode using protective clothing and the negative pressure ward.
Therefore, how to configure an active air protection system for medical workers, or other related personnel in infectious disease control wards or other applications where a user protection is required, to cover the medical worker and related personnel with positive pressure to form a protective barrier to further reduce the risk of medical workers and the related personnel from being infected by the patients in the infection control wards or virus or bacteria in or other application places, has become an important issue for the development of active protection technology in the industry.

In order to achieve the objective of making the wind speed in the location of the person 700 different from that in other location, the disclosure adopts two systems including a person identification system 100 and a matrix wind field generation system 300, and also applies a series of technical means to implement the operations of applying the positive pressure on the location of the person 700 (such as a medical worker) and the negative pressure on the location of the patient 3, so as to achieve the special technical effect of air protection barrier.

According to the illustration for
Obviously, the disclosure can generate the first range circle based on the person range coordinate transmitted from the person identification system 100 because the person identification system 100 and the matrix wind field generation system 300 of the disclosure share the protected space; that is, the person identification system 100 and the matrix wind field generation system 300 have the same projection planes. The wind field control system 200 clearly has the person range coordinate of the person 700 generated by the person identification system 100 and the coordinates of the air supply devices and the air exhaust devices of the matrix wind field generation system 300, so that the wind field control system 200 can map the person range coordinate of the person 700 and the coordinates of the air supply devices and the air exhaust devices with each other.
Compared with the point or line range of the person range coordinate of the person 700, the coordinates of the air supply devices and the air exhaust devices defined as the first range circle are discontinuous. In practice, it is hard to directly map the person range coordinate of the person 700 to the coordinates of the air supply devices and the air exhaust devices indicating the first range circle, so the operation of setting the first range circle mush be redefined.

The first range circle of the disclosure can be defined by various particular embodiments, such as a center coordinate defining method, or a person range coordinate defining method. The center coordinate defining method will be described in the following paragraphs first. Please refer to

In
After at least one central air-supply device is defined as the central range circle and the first range circle is also defined, the wind speeds of the central air-supply device and the air supply devices of first range circle can be controlled to be different from the wind speed of other air supply devices; for example, the wind speeds of the central air-supply device and the air supply devices of the first range circle can be lower than the wind speeds of the other air supply devices, so as to produce positive pressure on the space of the first range circle, and the opposite operations can produce negative pressure. Alternatively, the wind speed of the central air-supply device can be minimum, the wind speeds of the air supply devices of the first range circle are second minimum, and the wind speeds of other the air supply devices are maximum; or the above control can be operated opposite. The above-mentioned control operations are executed by a control program of the wind field control system 200. The above-mentioned control operations are the control manner of the embodiments of
Besides the embodiment of controlling the wind speeds of the central air-supply device and the air supply devices of the central range circle (the embodiment of
The disclosure can define the first range circle and the central range circle based on the range coordinate of the detected person no matter which manner is used, and then control the wind speeds within the central range circle or the first range circle to be different from the wind speed of other part, so as to achieve the special technical effect of applying positive pressure or negative pressure on the local space. In concept, no matter the range coordinate of the detected person is enclosed by the central range circle or the first range circle, the disclosure produces the positive pressure or negative pressure on the space where the person is located, based on the air supply devices enclosing the range coordinate of the detected person.
In the embodiments of
The manner of using the center coordinate to define the first range circle has more applicability in a condition that the air supply device has a smaller size. When the size of the air supply device is larger, the first range circle may be excessive large, for example, in the embodiment of
The above-mentioned embodiment of the air supply device is implemented by technology of the full covered wind outlet device, that is, the air outlet (or air outlet) of the air supply device blows wind in full area. In other words, the air supply device blows wind through the square area of M cm×M cm at one time, and the wind speeds through parts of the entire area are the same.

According to the above description, the wind field control system 200 of the disclosure can control the matrix wind field generation system based on the person range coordinate of the person identification system 100, and define the first range circle or the central range circle to make the space, where the person 700 is located, under positive pressure or negative pressure. Some embodiments of control method are described in the following paragraphs to illustrate the method of generating and controlling the positive or negative pressure according to the disclosure.
Please refer to
In a step S101: the person identification is performed by the person identification system, and a person range coordinate is generated when a person is identified, wherein the person range coordinate is defined based on a projection coordinate of the protected space.
In a step 102, projection coordinates of the plurality of air supply devices and the plurality of air exhaust devices in the protected space are individually defined.
In a step 103, based on the person range coordinate, at least one of the plurality of air supply devices and at least one of the air exhaust devices corresponding to the person range coordinate are defined as the first range circle, and wind speeds produced by the at least one of the plurality of air supply devices and the at least one of the plurality of air exhaust devices located within the first range circle are controlled to be different from wind speeds produced by at least one of the plurality of air supply devices and at least one of the plurality of air exhaust devices not located within the first range circle, so as to form a first pressure difference range circle.
The flow shown in
An embodiment of defining the first range circle is described according to the flow of
In a step S111, the air supply devices and the air exhaust devices, which are passed by the person range coordinate, are defined as the first range circle.
In a step S112, it checks whether any one of the air supply devices and the air exhaust devices located in the space enclosed by the first range circle is not belonged to the first range circle, and if yes, the found air supply device or air exhaust device is defined to belong to the central range circle. According to the embodiment of
In a step S113, the wind speeds produced by the air supply devices and the air exhaust devices located in the central range circle and the first range circle are controlled to be different from that produced by the air supply devices and the air exhaust devices not located in the central range circle and the first range circle, so that a first pressure difference range circle can be formed.
The first pressure difference range circle can apply positive pressure or negative pressure upon the application scenario. For example, in a negative pressure ward, the positive pressure environment is applied to a medical worker, and the negative pressure environment is applied to a patient, so as to protect the medical worker; the pressure difference of the second pressure difference range circle is opposite to the pressure difference of the first pressure difference range circle.
For the condition that there is no central range circle, the disclosure further provides several embodiments of controlling the air supply devices of the first range circle to produce positive pressure by the manner of adjusting the air-supply wind speeds and the air-exhaust wind speeds. There are two manners of adjusting the positive pressures in the first range circle. In the first manner, the air-supply wind speeds of the air supply devices and the air-exhaust wind speeds of the air exhaust devices within the first range circle are adjusted to be lower than an initial setting value, and the wind speeds of other air supply devices and other air exhaust devices are set as the initial setting value. In the second manner, the air-supply wind speeds of the air supply devices and the air-exhaust wind speeds of the air exhaust devices not located within the first range circle are adjusted to be higher than the initial setting value. There are two manners of adjusting the negative pressure inside the first range circle includes the following operations. In the first manner, the air-supply wind speeds of the air supply devices and the air-exhaust wind speeds of the air exhaust devices located within the first range circle are adjusted to be higher than the initial setting value. In the second manner, the air-supply wind speeds of the air supply devices and the air-exhaust wind speeds of the air exhaust devices not located within the first range circle are adjusted to be lower than the initial setting value, and the air-supply wind speeds and air-exhaust wind speeds within the first range circle are set as the initial setting value. The first manner is to adjust the wind speeds within the first range circle, the second manner is to adjust the wind speeds not within the first range circle, the targets to be adjusted are different, but their technical effects are the same.
For the condition that there is a central range circle, the disclosure provides several embodiments of controlling the air supply device in the first range circle to produce positive pressure by the manner of adjusting the air-supply wind speed and the air-exhaust wind speed. In the manner of adjusting the positive pressure in the first range circle, the air-supply wind speeds of the air supply devices and the air-exhaust wind speeds of the air exhaust devices within the central range circle and the first range circle are adjusted to be lower than the initial setting value, and the wind speeds of other air supply devices and other air exhaust devices are set as the initial setting value, and the wind speeds within the central range circle is lower than that within the first range circle; that is, the wind speeds within the central range circle is minimum. In the manner of adjusting negative pressure in the first range circle, the air-supply wind speeds of the air supply devices and the air-exhaust wind speeds of the air exhaust devices within the central range circle and the first range circle are adjusted to be higher than the initial setting value, and the wind speeds within the central range circle is higher than that within the first range circle, that is, the wind speeds within the central range circle is maximum. According to the above-mentioned two manners, one is to adjust the wind speed within the first range circle, the other is to adjust the wind speed not within the first range circle, the target to be adjusted are different, but their technical effects are the same.
In a step S121, the center coordinate of the person is calculated based on the person range coordinate.
In a step S122, at least one air supply device and at least one air exhaust device closest to the center coordinate are selected to form the central range circle. As described above, the amount of the air supply devices in the central range circle may be 1, 2 or 4, as shown in
In a step S123, the air supply devices and the air exhaust devices enclosing the central range circle are defined as a first range circle, and it then checks whether the range enclosed by the first range circle fully covers the person range coordinate.
In a step S124, when the range enclosed by the first range circle does not fully cover the person range coordinate, at least one the air supply device and at least one air exhaust device covering the person range coordinate is selected and added into the first range circle.
the step S125, the wind speeds produced by the air supply devices and the air exhaust devices in the central range circle and the first range circle are controlled to be different from the wind speeds produced by the air supply devices and the air exhaust devices not located in the central range circle and the first range circle, so as to form the first pressure difference range circle.
According to above-mentioned contents, the first range circles defined the embodiments of
The above-mentioned wind field control method applies the full covered wind outlet devices and the full-covered air exhaust devices. The method of controlling the peripheral wind outlets device and the peripheral air exhaust devices will be illustrated in the following paragraphs. Please refer to
In a step S201, the person identification is performed by the person identification system, when the person is detected and identified, the person range coordinate of the person is generated. The person range coordinate is defined based on the projection coordinate of the protected space.
In a step S202, the individual projection coordinates of the air outlets of the air supply devices and the air outlets of the air exhaust devices in the protected space are defined.
In a step S203, the center coordinate of the person range coordinate is calculated. The air outlet configuration of the peripheral wind outlets device is different from that of the full covered wind outlet device, the air outlets of the peripheral wind outlets device are located on peripheral parts of the peripheral wind outlets device, and the air outlet of the full covered wind outlet device is entire surface. Therefore, the center of each air outlet of the peripheral wind outlets device is located at the center of a side of the peripheral wind outlets device, and the center of the air outlet of the full covered wind outlet device is located at the center of the entire surface of the peripheral wind outlets device. When the person range coordinate passes through a peripheral wind outlets device, the person range coordinate may only pass one, two or three of the air outlets, and it is hard to determine whether the passing location is inside or outside the person range coordinate. Therefore, the center coordinate of the person range coordinate can be used as a reference point to more accurately determine the relationship between the air outlets of the peripheral wind outlets device and the person range coordinate.
In a step S204, based on the person range coordinate, the air outlets of the air supply devices and the air outlets of the air exhaust devices corresponding to the person range coordinate are defined as the first range circle, the wind speeds produced by the air outlets of the air supply devices and the air outlets of the air exhaust devices within the first range circle are controlled to be different from the wind speeds produced by the air outlets of the air supply devices and the air outlets of the air exhaust devices not located within the first range circle, so as to form the first pressure difference range circle.
In a step S211, based on the person range coordinate, the air outlets of the air supply devices and the air outlets of the air exhaust devices having distances, from the center coordinate, higher than and most approaching the distance between the person range coordinate and the center coordinate are selected as the first range circle, and the air outlets of the first range circle enclose the person range coordinate. Compared with the full covered wind outlet device capable of enclosing the coordinate range of the person to form an enclosed structure, the peripheral wind outlets device has the air outlets located at the sides thereof, so the air outlets through which the person coordinate range passes may form an open structure and not be connected to each other. Therefore, an embodiment of the disclosure is to form an enclosed structure in which the air outlets are connected to each other.
In a step S212, the wind speeds produced by the air outlets of the air supply devices and the air outlets of the air exhaust devices within the first range circle are controlled to be lower than the wind speeds produced by the air outlets of the air supply devices and the air outlets of the air exhaust devices not located within the first range circle, so as to the positive-pressure difference range circle.
In a step S213, the wind speeds produced by the air outlets of the air supply devices and the air outlets of the air exhaust devices within the first range circle are controlled to be higher than the wind speeds produced by the air outlets of the air supply devices and the air outlets of the air exhaust devices not located within the first range circle, so as to form the negative-pressure difference range circle.
In a step S221, based on the person range coordinate, the air outlets of the air supply devices and the air outlets of the air exhaust devices through which the person range coordinate passes are selected as the first range circle.
In a step S222, the wind speeds produced by the air outlets of the air supply devices and the air outlets of the air exhaust devices located within the first range circle are controlled to be lower than the wind speeds produced by the air outlets of the air supply devices and the air outlets of the air exhaust devices not located within the first range circle, so as to form the positive-pressure difference range circle.
In a step S223, the wind speeds produced by the air outlets of the air supply devices and the air outlets of the air exhaust devices located within the first range circle are controlled to be higher than the wind speeds produced by the air outlets of the air supply devices and the air outlets of the air exhaust devices not located within the first range circle, so as to form the negative-pressure difference range circle.
The steps S211˜213 and the steps S221˜223 are methods of defining the first range circle. Furthermore, the central range circle can be further defined, as shown in
In a step S231, the air outlets of the air supply devices and the air outlets of the air exhaust devices enclosing the center coordinate are defined as the central range circle. The central range circle is implemented by the concept of enclosing structure, similar to the steps S211˜S213 of the above-described embodiment. Since the center coordinate is a point, the center coordinate may be located at or outside the air outlet of the peripheral wind outlets device. For example, in the embodiment of
In a step S232, the wind speeds produced by the air outlets of the air supply devices and the air outlets of the air exhaust devices within the first range circle are controlled to be lower than the wind speeds produced by the air outlets of the air supply devices and the air outlets of the air exhaust devices not located within the first range circle, and the wind speeds produced by the air outlets of the air supply devices and the air outlets of the air exhaust devices within the central range circle are lower than the wind speeds produced by the air outlets of the air supply devices and the air outlets of the air exhaust devices within the first range circle, so as to form the positive-pressure difference range circle.
In a step S233, the wind speeds produced by the air outlets of the air supply devices and the air outlets of the air exhaust devices located within the first range circle are controlled to be higher than the wind speeds produced by the air outlets of the air supply devices and the air outlets of the air exhaust devices not located within the first range circle, and the wind speeds produced by the air outlets of the air supply devices and the air outlets of the air exhaust devices located within the central range circle are controlled to be higher than the wind speeds produced by the air outlets of the air supply devices and the air outlets of the air exhaust device located within the first range circle, so as to form the negative-pressure difference range circle.
The purpose of the embodiment of the steps S231˜S233 is to produce the different wind speeds in the central range circle and the first range circle, to achieve the incremental or decremented wind speeds in the first range circle, or achieve the incremental or decremented wind speeds from the central range circle to the first range circle, and to other space.
Similarly, the steps S231˜S233 can control the air outlets not within the first range circle, to control the wind speeds of the air outlets not within the first range circle to be different from the wind speeds of the air outlets within the first range circle. The operations are same as that of the above-mentioned embodiment, so detailed descriptions are not repeated herein.
After the person is detected, the identity of the person (a medical worker or a patient) must be determined, to further determine how to provide air pressure protection to the person. Several embodiments will be illustrated in the following paragraphs.
In an embodiment of the disclosure, only one specific target has a tag (single tag), for example, only one of the medical worker and the patient has the tag according to the concept of either black or white. The particular operations of the embodiment are described in the following paragraphs. When the identified person has a tag, a first pressure difference range circle is formed; when the identified person does not have the tag, at least one of the air supply devices and at least one of the air exhaust devices corresponding to the person range coordinate are selected to form a first range circle, the wind speeds produced by the air supply devices and the air exhaust devices located within the first range circle are controlled to be different from the wind speeds produced by the air supply devices and the air exhaust devices not located within the first range circle, so as to form a second pressure difference range circle, and the second pressure difference range circle is opposite to the first pressure difference range circle on pressure difference.
In another embodiment of the disclosure, two tags are adopted. When the identified person has a first tag, the first pressure difference range circle is formed; when the identified person has a second tag, the second pressure difference range circle is formed, and the second pressure difference range circle is opposite to the first pressure difference range circle on pressure difference.

In addition, in another embodiment of the disclosure, the air supply matrix can also be arranged on the bottom surface of the protection space 1, and the air exhaust matrix can be arranged on the top surface of the protection space 1. The architecture in
According to the various embodiments, the disclosure identifies the person 700, defines the location range (the first range circle) of the person and produces different wind speeds, to produce different wind barrier on the space where the person is located, to create a protective wind barrier space, thereby implementing the active protection for the medical worker and other person who needs to be protected. The active protection is equivalent to a protective air barrier following and moving with the medical worker. The technical solution of the disclosure is able to apply a protective air barrier on the medical worker in the existing negative pressure ward which is still defective, thereby reducing the possibility of medical worker being infected.
The disclosure disclosed herein has been described by means of specific embodiments. However, numerous modifications, variations and enhancements can be made thereto by those skilled in the art without departing from the spirit and scope of the disclosure set forth in the claims.
