Description

Technical Field

[0001] The present invention relates to a wind farm system, and more particularly to a wind pressure generating system with protective function and a method for generating protective air pressure difference. Background Art

[0002] Severe acute respiratory syndrome (SARS) (COVID-19) is one of the deadliest epidemics in human history, and has infected more than 100 million people. Since COVID-19 is a respiratory disease, it is similar to the common cold virus and is an epidemic that can easily cause large-scale transmission.

[0003] Due to the global large-scale spread of COVID-19, major problems have arisen, such as strict control of infectious diseases, collapse of the medical system, and impact on the economic system. The medical system itself has become the most important place for infectious disease control because it must treat COVID-19 patients. Therefore, due to the high infectiousness of COVID-19 patients, wards are given priority to admitting them to negative pressure wards to prevent the virus in the ward from spreading to other places outside the ward. In addition, medical staff who come into contact with COVID-19 patients must also wear protective clothing and other equipment to prevent them from being infected.

[0004] Even if the ward is a negative pressure ward and has gone through the standard wearing and disinfection procedures for protective clothing, it is still impossible to prevent medical staff from being infected while treating COVID-19 patients. A hospital in Taiwan, China, had a cluster infection caused by patients, in which the doctor was infected while treating the patient. It can be seen that the existing infectious disease control model of protective clothing combined with negative pressure wards has considerable room for improvement.

[0005] Therefore, how to configure an active air protection system for medical staff or other relevant personnel in infectious disease control wards or other application places that require user protection, so that the medical staff or the local area of ​​each of the above personnel can be covered with positive pressure to form a protective layer for them, so as to further reduce the risk of medical staff or other personnel being infected by viruses or bacteria from patients in infection control wards or other application places, has become an important issue in the development of active protection technology. Summary of the invention

[0057] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0058] The present invention utilizes the natural laws of fluid mechanics to detect the position of a person and select the air supply device above and the exhaust device below the position of the person to make the wind speed different from that of the air supply device and the exhaust device at other non-person positions, thereby making the wind pressure of the space where the person is located different from the wind pressure of the space where the person is located, thereby generating positive or negative pressure at the position where the person is located, thereby achieving the special technical effect of the air protection layer within the range of the person's position.

[0059] Please refer to Figure 1 , a schematic cross-sectional view of a protective space in a specific embodiment of the present invention. The present invention uses several systems to create positive or negative pressure at the location of the person. Please also refer to Figure 2A , a system architecture diagram of the wind pressure generating system with protective function of the present invention. Figure 1As shown, the present invention utilizes a matrix-type wind generating system 300 disposed on the top and bottom surfaces (above the floor 2 ) of the protective space 1 , so that the wind speed can be different within the range of the position of the person 700 .

[0060] In order to achieve the purpose of making the wind speed at the position of person 700 different from that at other positions, the present invention adopts two systems: a person identification system 100 and a matrix-type wind power generation system 300, and uses a series of technical means to achieve positive pressure at the position where person 700 (such as medical staff) is located, and negative pressure at the position where patient 3 is located, thereby achieving the special technical effect of an air protection layer. As shown in the figure, when the matrix-type wind power generation system 300 is controlled, the air supply device above the position where person 700 is located and the exhaust device below the position where person 700 is located make their wind speed "less than" that of other air supply devices and exhaust devices next to them, a fluid mechanics pressure difference will be generated, thereby making the space where person 700 is located a positive pressure state, such as Figure 1 On the contrary, when the matrix wind power generation system 300 controls the air supply device above the position of the person 700 and the exhaust device below to make the wind speed "greater" than other air supply devices and exhaust devices next to it, a fluid dynamics pressure difference will be generated, and the space where the person 700 is located will be in a negative pressure state. Therefore, the person recognition system 100 that accurately confirms the position of the person 700 is very important.

[0061] There are many technologies that can be used in the person recognition system 100, such as image recognition system, ultrasonic image recognition system, lidar image recognition system, infrared thermal image recognition system, pressure pad system, etc. These person recognition systems can effectively identify the presence of a moving person 700 and his / her position. The location of the person recognition system 100 can be set according to the size of the protective space 1 and the specification provided by the person recognition system 100. Figure 2B As shown, the person recognition system 100 uses a person recognition controller 110, a person recognition sensor 121, a person recognition sensor 122, ... a person recognition sensor 12N. In this embodiment, the person recognition sensors are arranged on the top surface of the protection space, and have interlaced scanning spaces with each other, so that the position of the person 700 and the state of his movement can be accurately sensed.

[0062] Next, please refer back to Figure 2A and Figure 2C The wind pressure generating system with protective function includes several main systems: a person recognition system 100, a wind field control system 200, a matrix wind power generating system 300 and a filtering system 400. The person recognition system 100 is used to recognize at least one person and generate at least one person range coordinate of the at least one person in the protective space 1, for example, Figure 1The figure 700 is shown in the figure. The matrix-type wind power generating system 300 includes an air supply matrix and an air exhaust matrix, wherein the air supply matrix is ​​arranged on the top surface of the protective space 1 and the air exhaust matrix is ​​arranged on the bottom surface of the protective space 1. The air supply matrix and the air exhaust matrix each have a plurality of air supply devices and a plurality of air exhaust devices, each of the air supply devices and each of the air exhaust devices are arranged facing each other (a one-to-one, many-to-one or one-to-many mode can be adopted) and each has an air supply device coordinate and an exhaust device coordinate. Each of the air supply devices and each of the air exhaust devices receives a wind field control instruction to generate corresponding air supply wind speed and exhaust wind speed. The filtering system 400 connects the air supply matrix and the exhaust matrix with a ventilation duct 500, so that the air flowing through the air supply matrix and the exhaust matrix can be filtered and disinfected. The wind field control system 200 (for example, using a PLC / programmable logic controller, an industrial computer server, etc.) is connected to the person recognition system 100 and the matrix wind power generation system 300, receives at least one person range coordinate transmitted by the person recognition system 100, calculates a wind field control range parameter based on at least one person range coordinate, and maps the wind field control range parameter to the supply matrix and exhaust matrix in the matrix wind power generation system 300 to select each of the air supply devices and each of the exhaust devices in at least one first range circle, and outputs the wind field control instruction to make the supply wind speed of each of the air supply devices in the first range circle different from the supply wind speed of each of the air supply devices in non-first range circle, and make the exhaust wind speed of each of the exhaust devices in the first range circle different from the exhaust wind speed of each of the exhaust devices in non-first range circle.

[0063] like Figure 2C As shown, in the protective space 1, the air supply device 310-1, air supply device 310-2 ... air supply device 310-N arranged on the top surface, and the exhaust device 320-1, exhaust device 320-2 ... exhaust device 320-N arranged on the bottom surface are arranged one-to-one up and down, and are respectively connected to the ventilation duct 500. The direction (wind direction) of the entire air flow is: the wind 611, wind 612 ... generated by the air supply device 310-1, air supply device 310-2 ... air supply device 310-N blows downward, and the wind 621, wind 622 ... exhausted by the exhaust device 320-1, exhaust device 320-2 ... exhaust device 320-N, and then to the wind 630 before the filter system 400, after passing through the filter system 400, it becomes clean wind 640, and then turns to the wind 650 at the air inlet of the air supply device 310-1 .... This cycle is endless. The main driving force of this air circulation is the air supply device 310-1, the air supply device 310-2...the air supply device 310-N, and the exhaust device 320-1, the exhaust device 320-2...the exhaust device 320-N.

[0064] Next, please refer to Figure 3A , Figure 3B , a functional block diagram of the air supply device 310 and the air exhaust device 320 of the present invention. The air supply device 310 includes: an air inlet 310c, connected to the ventilation duct 500; a fan 310d, arranged facing the air inlet 310c; a motor 310a, driving the fan 310d, and after rotating, the fan 310d brings the air (wind 650) from the air inlet 310c into: a damper 310e, arranged at the air outlet of the fan 310d, used to control the air outlet volume of the fan 310d; a screen 310f, arranged at the air outlet of the damper 310e, used to even the air outlet volume of the damper 310e; an air supply port 310g, arranged at the air outlet of the screen 310f, and facing the protective space 1; a controller 310b, connected to the motor 310a and the damper 310e, after receiving the wind field control instruction (from the wind field control system 200), adjusts the speed of the motor 310a and the size of the damper 310e, so as to adjust the air supply wind speed. The exhaust device 320 includes: an air inlet 320c, facing the protective space 1; a fan, arranged facing the air inlet 320c; a damper 320e, arranged at the air outlet of the fan 320d, for controlling the exhaust volume of the fan 320d; a motor 320a, driving the fan 320d, and after rotation, the fan 320d brings the air (wind 611) from the air inlet 320c into: an exhaust port 320f, arranged at the air outlet of the damper 320e, facing the ventilation duct 500, and exhausting the wind 621; a controller 320b, connected to the motor 320a and the damper 320e, after receiving the wind field control instruction (from the wind field control system 200), adjusts the speed of the motor 310a and the size of the damper 320e, so as to adjust the exhaust wind speed.

[0065] From the above FIG. 2A to FIG. 2C It can be seen from the description that the wind field control system 200 of the present invention dominates the entire system process. The wind field control system 200 generates a corresponding first range circle after calculation from at least one person range coordinate received from the person recognition system 100. The air supply device and the exhaust device defined by this first range circle are the objects for which the wind field control system 200 mainly adjusts the wind speed. Generally speaking, when no one is present, the wind field control system 200 can issue wind field control instructions in a manner of equal wind speed, that is, the air supply wind speed generated by each air supply device is the same, and the exhaust wind speed generated by each exhaust device is the same. What's more, the exhaust wind speed is greater than the supply wind speed, which is the basic condition for achieving a negative pressure ward.

[0066] Obviously, the present invention can generate the corresponding first range circle through the person range coordinates transmitted by the person recognition system 100 because the person recognition system 100 of the present invention and the matrix wind power generation system 300 share the protection space, that is, the two have a common projection plane. The wind farm control system 200 clearly grasps the person range coordinates of the person 700 generated by the person recognition system 100 and the coordinates of each air supply device and exhaust device of the matrix wind power generation system 300, so the two can be mapped to each other.

[0067] However, compared to the character range coordinates for the character 700, which can be a point or a linear range, the coordinates of the air supply device and the exhaust device represented by the first range circle are discontinuous. Therefore, in fact, the character range coordinates of the character 700 and the coordinates of the air supply device and the exhaust device represented by the first range circle cannot directly correspond to each other, and therefore, they must be redefined.

[0068] Next, please refer to FIG. 4A to FIG. 4E , which is a specific embodiment of the present invention using the character range coordinates of the character 700 to set the first range circle. Figure 4A The figure is the upward projection space 901 of the protection space 1. It can be seen in the figure that the person 700 moves from point P1 to point P2. At this time, for the person recognition system 100 (for example, an image recognition system or an infrared image recognition system, an ultrasonic image recognition system), the image data captured by the person recognition system 100 is as follows: Figure 4B As shown, the projection space 902 identified by the person recognition system 100 of the protection space 1, the person 700 is displayed as a person range 810-1 and a person range 810-2. The person recognition system 100 transmits the person range coordinates representing the person range 810-1 and the person range 810-2 to the wind farm control system 200. The wind farm control system 200 can calculate the center coordinates of the person range 810-1 and the person range 810-2 according to the person range coordinates. Next, please refer to Figure 4C , the projection space 903 of the air supply device viewed from above in the protection space 1, after the wind farm control system 200 converts the projection space to the projection space 903 of the air supply device, the character range coordinates of the character range 810-1 and the character range 810-2 can be overlapped with the projection space 903 of the air supply device, wherein the center coordinates of point P1 and point P2 are (X1, Y1) and (X2, Y1), respectively. Then, the wind farm control system 200 can define the first range circle according to the character range coordinates of the character range 810-1 and the character range 810-2.

[0069] There are many specific embodiments of the method of defining the first range circle of the present invention, for example, the center coordinate definition method and the character range coordinate definition method. FIG. 4D to FIG. 4E .exist Figure 4DIn the wind farm control system 200, the central air supply device is specified by the calculated central coordinates (X1, Y1) of the point P1, and the corresponding central exhaust device is also specified, that is, the central air supply device and the central exhaust device are the coordinates covering the point P1. However, the present embodiment happens to be: the air supply device and the exhaust device covering the central coordinates (X1, Y1) of the point P1 are one, however, other situations may be that the central coordinates of the point P1 are located exactly between two air supply devices, or between four air supply devices. Therefore, the central coordinates of the point P1 may actually correspond to at least one central air supply device and central exhaust device. The number of these central air supply devices and central exhaust devices is affected by the structure of the air supply matrix and the air exhaust matrix. For example Figure 4C For a matrix with a square and compact structure, the maximum number of central air supply devices associated with point P1 is 4; Figure 4K Then it is a matrix of 340 square staggered air supply devices, and the number of the maximum central air supply devices associated with point P1 is 3; Figure 4L It is a hexagonal honeycomb structure matrix of the air supply device 330, and the maximum number of central air supply devices associated with point P1 is 3.

[0070] Back to Figure 4D , the central coordinate (X1, Y1) corresponds to an air supply device, which is defined as the central air supply device 310-C0 by the wind farm control system 200, and the nine air supply devices surrounding the central air supply device 310-C0 are defined as the air supply devices 310-C1 of the first range circle, and the 14 air supply devices surrounding the air supply device 310-C1 of the first range circle are defined as the air supply devices 310-C2 of the second range circle, and so on. For the exhaust device, the procedure is the same and will not be described in detail here.

[0071] Figure 4E In the figure 700, the character moves to point P2, and its center coordinate (X2, Y1) also corresponds to an air supply device, which is defined as the central air supply device 310-C0 by the wind farm control system 200, and the nine air supply devices surrounding the central air supply device 310-C0 are defined as the air supply device 310-C1 of the first range circle, and the 14 air supply devices surrounding the air supply device 310-C1 of the first range circle are defined as the air supply device 310-C2 of the second range circle, and so on. For the exhaust device, the procedure is the same, and no further description is given here.

[0072] After defining the central air supply device (more than one) as the central range circle and the first range circle, the wind speed of the corresponding central air supply device and the first range circle air supply device is controlled to be different from the other wind speeds. For example, the wind speed of the central air supply device and the first range circle air supply device is lower than the wind speed of other air supply devices, which can cause positive pressure in the first range circle space. On the contrary, negative pressure can be caused. Alternatively, the wind speed of the central air supply device is the smallest, the wind speed of the air supply device in the first range circle is the second largest, and the wind speed of the air supply devices in other parts is the largest; or vice versa. These controls are all executed by the control program of the wind farm control system 200. This is Figure 4D , Figure 4E The control method of the embodiment of the present invention.

[0073] In addition to controlling the wind speed of the central air supply device and the air supply device in the central range circle ( Figure 4D , Figure 4E ), another way is to control the wind speed of other air supply devices other than the central air supply device and the air supply device in the central range circle to be less than or greater than the wind speed of the central air supply device and the air supply device in the central range circle. Figure 5A , Figure 5B In this embodiment, the central range circle is defined as all the air supply devices 310-C0 contained in the character range coordinates of the character range 810-1. There are 9 air supply devices in the figure. The air supply devices outside are surrounded by the air supply devices 310-C1 of the first range circle, totaling 24; the air supply devices 310-C2 of the second range circle outside the first range circle; the air supply devices 310-C3 of the third range circle outside the second range circle, and so on. The air supply devices of the first range circle, the second range circle, and the third range circle are controlled so that their wind speeds are different from those of the air supply devices of the central range circle. Similarly, when the wind speed of the central range circle is the smallest, positive pressure can be generated in its spatial range, and vice versa, negative pressure can be generated.

[0074] Regardless of the method, the present invention can define the first range circle, the center range circle, etc. by the range coordinates of the person, and then achieve the special technical effect of positive pressure or negative pressure in the local space by making the wind speed in the center range circle or the first range circle different from the others. Conceptually, no matter which of the center range circle or the first range circle covers the range coordinates of the person, the present invention is based on the corresponding air supply device covering the range coordinates of the person to generate positive pressure or negative pressure in the space where the person is located (here, the so-called positive pressure or negative pressure is the pressure difference between the part adjacent to the center range circle, or the pressure difference between the part opposite to the first range circle).

[0075] exist Figure 4D , Figure 4EIn the embodiment, the size of the first range circle can just cover the character range 810-1 and the character range 810-2. This is an embodiment in which the size of the air supply device is 20 cm x 20 cm, the size of the three air supply devices is 60 cm, and the shoulder width of a general person is about 40 to 50 cm. If the size of the air supply device is larger or smaller, the number of projection planes of the air supply device corresponding to the character range 810-1 and the character range 810-2 may be different. Figure 4F , the size of the air supply device 310 is 20 cm x 20 cm, and the character 700 can be covered by 6 to 12 air supply devices; Figure 4G , the size of the air supply device 311 is 30 cm x 30 cm, and the character 700 can be covered by 4 to 9 air supply devices; Figure 4H , the size of the air supply device 312 is 40 cm x 40 cm, and the character 700 can be covered by 2 to 6 air supply devices; Fig. 4I The size of the air supply device 313 is 60 cm x 60 cm, and the character 700 can be covered by 1 to 4 air supply devices.

[0076] The method of defining the first range circle by the center coordinate is applicable when the size of the air supply device is small. However, when the size of the air supply device is larger, the first range circle may be too large, such as Figure 4H In the embodiment of the present invention, the first range circle may cover 12 air supply devices, and its range covers 240 cm x 240 cm, which does not meet the actual needs. Figure 4J Another approach is adopted, in which four air supply ports are arranged in an air supply device 370 of 40 cm x 40 cm, making it actually a 20 cm x 20 cm air supply port.

[0077] The above embodiments of the air supply device are full-coverage air supply device technologies, that is, the air outlet (or air outlet) of the air supply device is a way of discharging air over the entire area. In other words, the air supply device delivers air at a time in a square area of ​​M cm x M cm, and the air speed delivered by the area is the same.

The structure of the four-in-one full-cover exhaust device can be the same as that of the four-in-one full-cover air supply device, that is, multiple air inlets and multiple air doors are adopted. Among them, the air door 370e-1, the air door 370e-2, the air door 370e-3, and the air door 370e-4 are fully open / fully closed or adjustable in opening ratio. After the microcontroller 370b receives the wind field control instruction transmitted by the wind field control system 200, it controls the motor 370a and the air door 370e-1, the air door 370e-2, the air door 370e-3, and the air door 370e-4 so that the wind 611-1, wind 611-1, wind 611-1, wind 611-1 of the air supply port 370g-1, the air supply port 370g-2, the air supply port 370g-3, and the air supply port 370g-4 can be different.

[0079] Next, another specific embodiment of the air supply device of the present invention is described, namely, a peripheral air supply device and a peripheral exhaust device. 7A to 7E , the shape, functional block diagram and first range circle definition method embodiment of the square peripheral air supply device 350 of the present invention. The peripheral air supply device 350 includes air supply port 350g-1, air supply port 350g-2, air supply port 350g-3 and air supply port 350g-1, a total of four. Air supply port 350g-1, air supply port 350g-2, air supply port 350g-3 and air supply port 350g-1 are respectively arranged on the periphery of the surface of the peripheral air supply device 350 facing the protection space 1, such as Fig. 7A shown.

[0080] Please refer to Figure 7B The peripheral air supply device 350 includes: an air inlet 350c connected to the ventilation duct 500; a fan 350d, which is arranged facing the air inlet 350c; a motor 350a, which drives the fan 350d, and after the rotation, the fan 350d brings the air (wind 650) from the air inlet 350c into: four dampers 350e-1, damper 350e-2, damper 350e-3, and damper 350e-4, which are arranged at the air outlet of the fan 350d to control the air outlet volume of the fan 350d; four screens 350f-1, screen 350f-2, screen 350f-3, and screen 350f-4, which are respectively arranged at the air outlets of the dampers 350e-1, dampers 350e-2, dampers 350e-3, and dampers 350e-4. Used to even out the air volume of dampers 350e-1, 350e-2, 350e-3 and 350e-4; four air outlets 350g-1, 350g-2, 350g-3 and 350g-4 are respectively arranged at the air outlets of screens 350f-1, 350f-2, 350f-3 and 350f-4, and face the protective space 1; controller 350b is connected to motor 350a and damper 3503, and after receiving the wind field control instruction (from the wind field control system 200), adjusts the speed of motor 350a and the size of dampers 350e-1, 350e-2, 350e-3 and 350e-4, so as to adjust the air supply speed. The structure of the four-in-one peripheral exhaust device can be the same as that of the four-in-one peripheral air supply device, that is, multiple air inlets and multiple air doors are adopted. Among them, the air door 350e-1, the air door 350e-2, the air door 350e-3, and the air door 350e-4 are fully open / fully closed or adjustable in opening ratio. After the microcontroller 350b receives the wind field control instruction transmitted by the wind field control system 200, it controls the motor 370a and the air door 370e-1, the air door 350e-2, the air door 350e-3, and the air door 350e-4 so that the wind 611-1, wind 611-1, wind 611-1, wind 611-1 of the air supply port 350g-1, the air supply port 350g-2, the air supply port 350g-3, and the air supply port 350g-4 can be different.

[0081] Next, please refer to Fig.7D and Fig. 7E When the center point A of the character range coordinates moves to the center point B, the wind field control system 200 moves the center range circle 350-C0 and the first range circle 350-C1 accordingly, and the center range circle moves from the air supply device 350N-M to the air supply device 350-(N+1)-(M+1).

[0082] Next, please refer to FIG. 8A to FIG. 8D, the shape of the hexagonal peripheral air supply device 360 ​​of the present invention and the method for defining the first range circle are implemented in the embodiment. 7A to 7E It can be seen from the embodiments that the difference between the two lies in the number of air outlets. The hexagonal peripheral air supply device 360 ​​of No. 8A has a total of six air outlets, which are divided into: air outlet 360g-1, air outlet 360g-2, air outlet 360g-3, air outlet 360g-4, air outlet 360g-5, and air outlet 360g-6. The surface facing the protection space is specifically arranged as follows: Figure 8B Honeycomb shape. Figure 8C and Fig.8D When the center point A of the character range coordinates moves to the center point B, the wind field control system 200 moves the center range circle 360-C0 and the first range circle 360-C1 accordingly, and the center range circle moves from the air supply device 360N-M to the air supply device 350-(N-1)-(M+1).

[0083] As can be seen from the above description, the present invention uses the wind farm control system 200 to control the matrix wind power generation system, and according to the person range coordinates of the person recognition system 100, a first range circle or a center range circle is defined to achieve positive pressure or negative pressure in the space where the person 700 is located. Below, several embodiments of the control method will be listed to illustrate the positive and negative pressure generation and control method of the present invention.

[0084] First, please refer to 9A to 9C The first embodiment of the present invention is a method for generating a protective air pressure difference by full coverage, and the main process comprises the following steps:

[0085] Step S101: Performing person recognition with the person recognition system. When a person is detected, a person range coordinate is generated. The person range coordinate is defined according to the projection coordinate of the protection space.

[0086] Step S102: defining individual projection coordinates of each of the air supply devices and each of the air exhaust devices in the protection space.

[0087] Step S103: Based on the character range coordinates, define each of the air supply devices and each of the exhaust devices corresponding to the character range coordinates as a first range circle, so that the wind speed generated by each of the air supply devices and each of the exhaust devices in the first range circle is different from the wind speed generated by each of the air supply devices and each of the exhaust devices in areas other than the first range circle, thereby forming a first pressure difference range circle.

[0088] Fig. 9AThe process has two main technical features: defining the first range circle by the range coordinates of the person, and controlling the wind speed in the first range circle to be different from that in the non-first range circle. In this way, an air pressure difference can be generated between the first range circle and the non-first range circle. As for how to define the first range circle by the range coordinates of the person, the present invention provides some specific embodiments:

[0089] Fig. 9B The process provides an embodiment of defining the first range circle: the air supply device passing through the character range coordinates is the first range circle. That is, the character range coordinates indicate the boundary coordinates of the character range, and all air supply devices or exhaust devices covering this boundary are the first range circle. Fig. 9B The embodiment comprises the following steps:

[0090] Step S111: The air supply devices and the air exhaust devices in the range coordinates of the person are defined as the first range circle.

[0091] Step S112: Check whether there are any undefined air supply devices and exhaust devices in the space surrounded by the first range circle. If yes, define it as a central range circle. Figure 4F In the embodiment of the present invention, the person 700 may be covered by 6 to 12 air supply devices, and the outermost circle is roughly the first range circle. That is, the number of air supply devices in the first range circle may be 6, 8 or 10, and the number of central range circles may be 0, 1 or 2. Therefore, when the first range circle is defined in the manner of this embodiment, there may be no central range circle in some cases.

[0092] Step S113: Make the wind speed generated by the air supply devices and exhaust devices in the central range circle and the first range circle different from the wind speed generated by the air supply devices and exhaust devices in non-central range circle and the first range circle, thereby forming a first pressure difference range circle.

[0093] The first pressure differential range circle can be positive pressure or negative pressure, depending on the application scenario. Taking a negative pressure ward as an example, if you want to protect medical staff, you provide a positive pressure environment for medical staff and a negative pressure environment for patients. In contrast, the second pressure differential range circle has a pressure difference opposite to the first pressure differential range circle.

[0094] Among them, when there is no central range circle, the present invention provides several embodiments for controlling the air supply device in the first range circle to generate positive pressure, that is, embodiments for adjusting the air supply wind speed and the exhaust wind speed. Adjusting the positive pressure in the first range circle: I. By adjusting the air supply wind speed and the exhaust wind speed of each of the air supply devices and each of the exhaust devices in the first range circle to be less than the initial setting value, the wind speed of other air supply devices and exhaust devices is the initial setting value; II. By adjusting the air supply wind speed and the exhaust wind speed of each of the air supply devices and each of the exhaust devices outside the first range circle to be greater than the initial setting value. Adjusting the negative pressure in the first range circle: I. By adjusting the air supply wind speed and the exhaust wind speed of each of the air supply devices and each of the exhaust devices in the first range circle to be greater than the initial setting value; II. By adjusting the air supply wind speed and the exhaust wind speed of each of the air supply devices and each of the exhaust devices outside the first range circle to be less than the initial setting value, the air supply wind speed of the first range circle is the initial setting value. The above two methods, one is to adjust the wind speed within the first range circle, and the other is to adjust the wind speed outside the first range circle. The objects adjusted by the two are different, but the technical effects obtained are the same.

[0095] When there is a central range circle, the present invention provides several embodiments for controlling the air supply device in the first range circle to generate positive pressure, that is, embodiments for adjusting the air supply wind speed and the exhaust wind speed. Adjusting the positive pressure in the first range circle: I. By adjusting the air supply wind speed and the exhaust wind speed of the central range circle, each of the air supply devices in the first range circle, and each of the exhaust devices to be less than the initial setting value, the wind speed of other air supply devices and exhaust devices is the initial setting value, and the wind speed of the part of the central range circle is less than the first range circle, that is, the wind speed of the central range circle is the smallest. Adjusting the negative pressure in the first range circle: I. By adjusting the air supply wind speed and the exhaust wind speed of the central range circle, each of the air supply devices in the first range circle, and each of the exhaust devices to be greater than the initial setting value, and the wind speed of the part of the central range circle is greater than the first range circle, that is, the wind speed of the central range circle is the largest. The above two methods, one is to adjust the wind speed in the first range circle, and the other is to adjust the wind speed of the non-first range circle. The objects of adjustment of the two are different, but the technical effects obtained are the same.

[0096] Fig. 9C The process provides another embodiment of defining the first range circle: defining the first range circle by the center coordinates. That is, the range of the first range circle is defined by the center coordinates calculated by the character range coordinates. Fig. 9C The embodiment comprises the following steps:

[0097] Step S121: Calculate a center coordinate of the character according to the character range coordinates.

[0098] Step S122: According to the central coordinate, at least one of the air supply devices and at least one of the air exhaust devices closest to the central coordinate are selected as a central range circle. As mentioned above, the number of air supply devices in the central range circle is Figure 4F For example, there may be 1, 2 or 4. Figure 4K , Figure 4L For the embodiment, there may be 1, 2 or 3.

[0099] Step S123: define each of the air supply devices and each of the air exhaust devices covering the central range circle as a first range circle, and check whether the range covered by the first range circle completely covers the range coordinates of the person.

[0100] Step S124: If the range covered by the first range circle does not completely cover the coordinates of the person range, at least one of the air supply device and the air exhaust device that can cover the coordinates of the person range is added to the first range circle.

[0101] Step S125: Make the wind speed generated by the air supply devices and exhaust devices in the central range circle and the first range circle different from the wind speed generated by the air supply devices and exhaust devices in non-central range circle and the first range circle, thereby forming a first pressure difference range circle.

[0102] Compare Fig. 9B and Fig. 9C It can be seen from the embodiments that the first range circles defined by the two may be the same or different. Fig. 9B In the embodiment, there may be no central range circle, and Fig. 9C In the embodiment, there must be a center range circle. Therefore, different methods for defining the first range circle may lead to first range circles of the same range, or they may be different. Once the center range circle and the first range circle are defined, the method for generating positive pressure and negative pressure is the same as described above, and no further elaboration is given here.

[0103] The above wind field control method is a control method when using a full-cover air supply device and a full-cover air exhaust device as embodiments. The following will describe the control method of the peripheral air supply device and the exhaust device. FIG. 10A to FIG. 10C , the method of generating protective air pressure difference in the periphery, the main process includes the following steps:

[0104] Step S201: Performing person recognition with the person recognition system. When a person is detected, a person range coordinate is generated. The person range coordinate is defined based on the projection coordinate of the protection space.

[0105] Step S202: defining respective projection coordinates of each of the air supply ports of each of the air supply devices and each of the air exhaust ports of each of the air exhaust devices in the protection space.

[0106] Step S203: Calculate a center coordinate among the character range coordinates. Unlike the full-coverage air supply device, the air supply outlets of the peripheral air supply device are located at the periphery, while the air supply outlets of the full-coverage air supply device are on the entire surface. Therefore, the center of the air supply outlets of the peripheral air supply device is located at the center of each edge, while the center of the air supply outlet of the full-coverage air supply device is located at the center of the entire surface. Therefore, when the character range coordinates pass through a peripheral air supply device, it is possible to pass through only one, two or three air supply outlets. And it is difficult to determine whether the position it passes through is inside or outside it. Therefore, by using the center coordinates of the character range coordinates as a reference point, the relationship between the air supply outlets of the peripheral air supply device and the character range coordinates can be more accurately grasped.

[0107] Step S204: Based on the character range coordinates, define each air supply outlet of each air supply device and each exhaust outlet of each exhaust device corresponding to the character range coordinates as a first range circle, so that the wind speed generated by each air supply outlet of each air supply device and each exhaust outlet of each exhaust device within the first range circle is different from the wind speed generated by each air supply outlet of each air supply device and each exhaust outlet of each exhaust device that are not in the first range circle, thereby forming a first pressure difference range circle.

[0108] An embodiment of defining the first range circle is as follows: Fig. 10B shown.

[0109] Step S211: According to the character range coordinates, select the air supply ports of the air supply devices and the exhaust ports of the exhaust devices that are larger than and closest to the distance between the character range coordinates and the center coordinates as a first range circle, and make the air supply ports of the first range circle surround the character range coordinates. Different from the full-coverage air supply device, since the full-coverage air supply device can "cover" the character coordinate range and form a closed structure; and the peripheral air supply device has air supply ports arranged at the periphery, so the air supply ports through which the character coordinate range passes may be open to each other but not connected to each other. Therefore, one embodiment of the present invention is to form a closed structure connected by air supply ports.

[0110] Step S212: Make the wind speed generated by each air supply outlet of each air supply device and each exhaust outlet of each air exhaust device within the first range circle smaller than the wind speed generated by each air supply outlet of each air supply device and each exhaust outlet of each air exhaust device outside the first range circle, thereby forming a positive pressure difference range circle.

[0111] Step S213: Make the wind speed generated by each air supply outlet of each air supply device and each exhaust outlet of each air exhaust device within the first range circle greater than the wind speed generated by each air supply outlet of each air supply device and each exhaust outlet of each air exhaust device outside the first range circle, thereby forming a negative pressure difference range circle.

[0112] Another embodiment of defining the first range circle is as follows: Fig. 10C shown.

[0113] Step S221: According to the character range coordinates, each of the air supply ports of each of the air supply devices and each of the air exhaust ports of each of the air exhaust devices corresponding to the character range coordinates are selected as a first range circle.

[0114] Step S222: Make the wind speed generated by each air supply outlet of each air supply device and each exhaust outlet of each air exhaust device within the first range circle smaller than the wind speed generated by each air supply outlet of each air supply device and each exhaust outlet of each air exhaust device outside the first range circle, thereby forming a positive pressure difference range circle.

[0115] Step S223: Make the wind speed generated by each air supply outlet of each air supply device and each exhaust outlet of each air exhaust device within the first range circle greater than the wind speed generated by each air supply outlet of each air supply device and each exhaust outlet of each air exhaust device outside the first range circle, thereby forming a negative pressure difference range circle.

[0116] Steps S211 to S213 and steps S221 to S223 are both methods for defining a first range circle. In addition, a central range circle may be further defined, such as Fig. 10D shown.

[0117] Step S231: Define the air supply ports of the air supply devices and the air exhaust ports of the air exhaust devices that surround the central coordinate as a central range circle. As in the above-mentioned embodiment, the central range circle here is based on the concept of surrounding, similar to steps S211 to S213. Since the central coordinate is a point, it may be located at the air supply port of the peripheral air supply device, or it may be located outside the air supply port. Figure 4FTake the embodiment as an example, if it is just located at the air supply outlet, the number of air supply outlets of the peripheral air supply device surrounding the central coordinate may be five, that is, one adjacent air supply outlet and four air supply outlets including the peripheral air supply device itself; it can also be one, that is, the air supply outlet. If the central coordinate is just located between two air supply outlets, then the number of air supply outlets of the peripheral air supply device surrounding the central coordinate is eight (closed encirclement), or two (open encirclement) can be used. If the central coordinate is located exactly between four air supply outlets, then the number of air supply outlets of the peripheral air supply device surrounding the central coordinate is four. And so on. The concept of encirclement here can be interpreted not only by the concept of closed encirclement in steps S111 to S113, but also by the concept of open encirclement.

[0118] Step S232: Make the wind speed generated by each air supply outlet of each air supply device and each exhaust outlet of each exhaust device within the first range circle smaller than the wind speed generated by each air supply outlet of each air supply device and each exhaust outlet of each exhaust device outside the first range circle, and make the wind speed generated by each air supply outlet of each air supply device and each exhaust outlet of each exhaust device within the central range circle smaller than the wind speed generated by each air supply outlet of each air supply device and each exhaust outlet of each exhaust device in the first range circle, thereby forming a positive pressure difference range circle.

[0119] Step S233: The wind speed generated by each air supply outlet of each air supply device and each exhaust outlet of each exhaust device within the first range circle is made greater than the wind speed generated by each air supply outlet of each air supply device and each exhaust outlet of each exhaust device outside the first range circle, and the wind speed generated by each air supply outlet of each air supply device and each exhaust outlet of each exhaust device within the central range circle is made greater than the wind speed generated by each air supply outlet of each air supply device and each exhaust outlet of each exhaust device in the first range circle, thereby forming a negative pressure difference range circle.

[0120] In the embodiment of step S231 to step S233, the purpose is also to create wind speeds in different layers such as the central range circle and the first range circle, so as to achieve a state in which the wind speed increases or decreases in the first range circle, or from the central range circle to the first range circle to other parts.

[0121] Similarly, steps S231 to S233 may also be performed by controlling the air outlets outside the first range circle to make their speed different from the air speed of the air outlets within the first range circle. The method is as described above and will not be repeated here.

[0122] However, after detecting a person, it is necessary to determine who the person is, whether it is a medical staff or a patient, and then know how to protect the person from pressure difference.

[0123] In one embodiment of the present invention, only one specific object has a label, that is, a single label, such as a medical staff or a patient, that is, a black-and-white concept. The specific method is: when the identified person has a label, the first pressure difference range circle is formed; when the identified person does not have the label, according to the person range coordinates, each of the air supply devices and each of the exhaust devices corresponding to the person range coordinates are selected as a first range circle, so that the wind speed generated by each of the air supply devices and each of the exhaust devices in the first range circle is different from the wind speed generated by each of the air supply devices and each of the exhaust devices not in the first range circle, thereby forming a second pressure difference range circle, and the pressure difference of the second pressure difference range circle is opposite to that of the first pressure difference range circle.

[0124] Next, in another embodiment of the present invention, a double label approach is adopted. That is, when the identified person has a first label, the first pressure difference range circle is formed; when the identified person has a second label, a second pressure difference range circle is formed, and the pressure difference of the second pressure difference range circle is opposite to that of the first pressure difference range circle.

[0125] The tag is a physical tag of a radio frequency identification tag, or a soft tag (Soft Tag) generated by the person recognition system to determine a specific person. The so-called soft tag is generated by the person recognition device based on the judgment of its system, for example, judging the material of the medical staff's clothing (protective clothing) and the patient's clothing (cotton clothing), and then judging their identity to generate a corresponding soft tag.

[0126] Next, please refer to Fig.11 , which is another embodiment of the present invention, an embodiment of the configuration of the exhaust matrix set on the floor 2. Fig.11It can be found that exhaust devices 320-1, exhaust devices 320-2, exhaust devices 320-3, exhaust devices 320-4, exhaust devices 320-5, exhaust devices 320-6, exhaust devices 320-7, exhaust devices 320-8, exhaust devices 320-9, exhaust devices 320-10, exhaust devices 320-11, and exhaust devices 320-12 are all arranged around the floor 2 (bottom corners of the surrounding walls). In some places, it is not suitable to arrange the exhaust devices in most of the space of the floor 2 as in the exhaust matrix in the aforementioned embodiment, and it is necessary to arrange them around the floor. In addition, exhaust devices 320-1, exhaust devices 320-2, exhaust devices 320-3, etc. can adopt the aforementioned full-coverage exhaust devices or peripheral exhaust devices, or a mixture of the two. Similarly, the air supply devices in the air supply matrix may also be a mixture of full-coverage air supply devices or peripheral air supply devices.

[0127] In addition, in another embodiment of the present invention, the air supply matrix may be disposed on the bottom surface of the protection space, and the air exhaust matrix may be disposed on the top surface of the protection space. Fig.11 The structure can also be configured in reverse as in the present embodiment.

[0128] From the above multiple embodiments, it can be seen that the present invention realizes the character recognition of the character 700, the range definition of the character (first range circle) and the generation of different wind speeds, thereby generating different wind pressures around the character, and creating a protective wind pressure space, thereby realizing active protection for medical staff or other personnel to be protected. This active protection is equivalent to an air protective cover, and it is always at the side and moves with the position of the medical staff. Therefore, the implementation of the technology of the present invention allows medical staff to add a layer of protection net to medical staff when modern negative pressure wards still have defects, thereby reducing the possibility of medical staff being infected.

[0129] The above-described embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or changes made by those skilled in the art based on the present invention are within the protection scope of the present invention. The protection scope of the present invention shall be subject to the claims.
