Description

Wind pressure generating system with protective function

This new model relates to a wind farm system, in particular to a wind pressure generating system with protective function.

Severe special infectious pneumonia (Coronavirus disease 2019, abbreviation: COVID-19, abbreviated as new coronary pneumonia), is one of the most fatal epidemics in human history, and has infected more than 100 million people. Since COVID-19 is a disease transmitted through the respiratory tract, it is an epidemic that is likely to cause large-scale infection, just like the cold virus.

Due to the large-scale global spread of COVID-19, it has led 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. The medical system itself, because it must treat COVID-19 patients, has become the most important place for infectious disease control. Therefore, due to the high infectivity of the wards where the COVID-19 patients are admitted, the priority is to allow them to enter the negative pressure ward, so as 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.

Even if the ward is a negative pressure ward and goes through the standard wearing procedures and disinfection procedures of protective clothing, it is still unavoidable that medical staff are infected during the treatment of COVID-19 patients. The situation of cluster infections in the hospital caused by patients with new coronary pneumonia diagnosis number 812 in Butao Hospital in Taiwan is that doctors were infected during the diagnosis and treatment of patients. It can be seen that there is considerable room for improvement in the existing protective clothing combined with the infectious disease control mode of the negative pressure ward.

Therefore, how to configure an active air protection system for medical staff or other related personnel in infectious disease control wards or other application places that require user protection, so that the medical staff or the local surroundings of these personnel can be positively pressured Coating, forming a protective layer on it, to further reduce the risk of virus or bacteria infection of patients in the infection control ward or other application places for medical staff or other personnel, and has become an important topic for the development of active protection technology.

In view of this, this new model proposes a wind pressure generation system with protective function, using the principle of fluid mechanics, through the character recognition system to identify the existence and position of the character, and then control the matrix-type wind generation system to generate the space corresponding to the character Different from the flow velocity of other parts, it can generate positive pressure or negative pressure in the space where the character exists, so as to produce the special technical effect of the air shield for the character.

In order to achieve the above objective, the present invention proposes a wind pressure generating system with protective function, applied to a protective space, including: a character recognition system for identifying at least one character, and generating the at least one character in the protective space At least one character range coordinate; a matrix type wind generating system, including an air supply matrix and an exhaust matrix, the air supply matrix is arranged on the top surface of the protective space and the exhaust matrix is arranged on the bottom surface of the protective space, the air supply matrix The exhaust matrix and the exhaust matrix each have a plurality of air supply devices and a plurality of air exhaust devices. The air supply devices and the exhaust devices are arranged facing each other and each have an air supply device coordinate and an air exhaust device coordinate. The air supply devices Receive a wind field control command with these exhaust devices to generate corresponding air supply wind speed and exhaust air Wind speed; a filtering system connecting the air supply matrix and the exhaust air matrix with a ventilation duct, so that the air flowing in the air supply matrix and the exhaust air matrix can be filtered and disinfected; and a wind farm control system connected to the character recognition system , Receiving the at least one character range coordinate, calculating a wind field control range parameter according to the at least one character range coordinate, and mapping the wind field control range parameter to the air supply matrix and the exhaust matrix to select at least a first range The air supply devices and the air exhaust devices of the circle, and output the wind field control command, so that the air supply wind speed of the air supply devices in the first range circle is compared with the air supply of the air supply devices outside the first range circle The wind speed is different, and the exhaust wind speed of the exhaust devices in the first range circle is different from the exhaust wind speed of the exhaust devices not in the first range circle, so as to form a protective wind pressure for the at least one person.

The new model uses the natural laws of fluid mechanics to detect the position of the person, and select the air supply device above and the exhaust device below the position corresponding to the person's position, so that the wind speed of the air supply device and exhaust device is different from other non-human positions. , So that the wind pressure in the space where the character is located is different from the wind pressure in the non-character position space, and then positive or negative pressure can be generated on the position of the character, thereby realizing the special technology of the air protection layer in the range of the character position effect.

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

In order to achieve the purpose of making the wind speed of the character 700 different from other positions, the present invention adopts two systems: the character recognition system 100 and the matrix wind generation system 300, and realizes the character 700 ( For example, the positive pressure at the position of the medical staff) and the negative pressure at the position of the patient 3 can achieve the special technical effect of the air protection layer. As shown in the figure, when the matrix wind generating system 300 is controlled, the air supply device located above the character 700 and the air exhaust device below the position of the figure 700 are controlled to make the wind speed "smaller" than other air supply devices and exhaust devices next to it. The pressure difference of fluid mechanics, in turn, causes the space where the character 700 is located to have a positive pressure, as shown in FIG. 1. Conversely, when controlling the matrix type wind generating system 300, the air supply device located above the character 700 and the exhaust device below the position of the character 700 make the wind speed "larger" than the other next to it. When the air supply device and the air exhaust device are used, a fluid dynamic pressure difference will be generated, and the space where the character 700 is located will be under negative pressure. The person recognition system 100 that accurately confirms the position of the person 700 is very important.

The person recognition system 100 currently has many technologies that can be used, for example, an image recognition system, an ultrasonic image recognition system, a LiDAR image recognition system, an infrared thermal image recognition system, a pressure pad system, etc., all of these person recognition systems can be used. Effectively recognize the presence of a moving character 700 and its location. The location of the person recognition system 100 can be set according to the size of the protective space 1 and the specifications provided by the person recognition system 100. As shown in FIG. 2B, the person recognition system 100 employs 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. Therefore, the position of the person 700 and the state of its movement can be accurately sensed.

Next, please refer back to Figures 2A and 2C. The wind pressure generation system with protective function includes several main systems: the character recognition system 100, the wind farm control system 200, the matrix wind generation system 300, and the filter system 400. The character recognition system 100 is used for recognizing at least one character and generating at least one character range coordinates of the at least one character in the protection space 1, for example, the character 700 in FIG. 1. The matrix wind generating system 300 includes an air supply matrix and an air exhaust matrix. The air supply matrix is arranged on the top surface of the protection space 1 and the exhaust air matrix is arranged on the bottom surface of the protection space 1. The air supply matrix and the exhaust air matrix each have a plurality of air supply devices and a plurality of air exhaust devices, and the air supply devices and the air exhaust devices are arranged facing each other (one-to-one, many-to-one or one-to-many mode can be adopted) And each has an air supply device coordinate and an air exhaust device coordinate. The air supply devices and the air exhaust devices receive a wind field control command to generate corresponding air supply wind speed and exhaust air speed. The filter system 400 connects the air supply matrix and the exhaust air matrix with a ventilation duct 500, so that the air flowing in the air supply matrix and the exhaust air matrix can be filtered and disinfected. The wind farm control system 200 (for example, using a PLC/programmable logic controller, industrial computer server, etc.) is connected to the character recognition system 100 and the matrix wind generation system 300, and receives at least one of the data from the character recognition system 100 Character range coordinates, calculate a wind farm control range parameter based on at least one character range coordinate, and map the wind farm control range parameter to the air supply matrix and exhaust matrix in the matrix wind generation system 300 to select at least one first range circle The air supply devices and the air exhaust devices, and output the wind field control command, so that the air supply wind speed of the air supply devices in the first range circle and the air supply wind speed of the air supply devices not in the first range circle Different, and make the exhaust wind speed of the exhaust devices of the first range circle different from the exhaust wind speed of the exhaust devices of the non-first range circle.

As shown in Figure 2C, in the protective space 1, the air supply device 310-1, the air supply device 310-2...the air supply device 310-N arranged on the top surface, and the exhaust device 320 arranged on the bottom surface -1. The exhaust device 320-2...The exhaust device 320-N is arranged in one-to-one correspondence up and down, and they are respectively connected to the ventilation duct 500. The direction of the entire air flow (wind direction) is: the air supply device 310-1, the air supply device 310-2... the wind 611 and the wind 612 generated by the air supply device 310-N, downward After blowing, the wind 621, wind 622... from the exhaust device 320-1, the exhaust device 320-2...the exhaust device 320-N before the filter system 400 After passing through the filter system 400, the air 630 becomes clean air 640, and then turns to the air 650 at the air inlet of the air supply device 310-1... This cycle is endless. The main power of this air circulation is the air supply device 310-1, the air supply device 310-2... the air supply device 310-N, as well as the air exhaust device 320-1, the air exhaust device 320-2..... .Exhaust device 320-N.

Next, please refer to FIGS. 3A and 3B, the functional block diagrams 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 a ventilation pipe The duct 500; the fan 310d is set facing the air inlet 310c; the motor 310a drives the fan 310d, and after rotating, the fan 310d brings in the air (wind 650) from the air inlet 310c: the damper 310e is set at the outlet of the fan 310d, Used to control the air output of the fan 310d; the screen 310f is set at the air outlet of the damper 310e to uniformize the air output of the damper 310e; the air outlet 310g is set at the air outlet of the screen 310f and faces the protection Space 1: The controller 310b is connected to the motor 310a and the damper 310e, and after receiving the wind field control command (from the wind field control system 200), it adjusts the speed of the motor 310a and the size of the damper 310e to adjust the blowing 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 outlet of the fan 320d to control the exhaust air volume of the fan 320d; a motor 320a, The fan 320d is driven, and after rotating, the fan 320d brings in the air (wind 611) from the air inlet 320c: the air outlet 320f is arranged at the air outlet of the damper 320e and faces the ventilation duct 500 to discharge the air 621; the controller 320b, After connecting the motor 320a and the damper 320e, after receiving the wind field control command (from the wind field control system 200), the rotation speed of the motor 310a and the size of the damper 320e are adjusted to adjust the exhaust wind speed.

From the above description of Fig. 2, it can be seen that the wind farm control system 200 of the present invention dominates the entire system flow. The wind field control system 200 receives at least one character range coordinate from the character recognition system 100, and after calculation, generates a corresponding first range circle. The air supply device and the air exhaust device defined in the first range circle are the objects that the wind farm control system 200 mainly needs to adjust the wind speed. Generally speaking, when the wind farm control system 200 is unmanned, it can issue wind farm control commands in a constant wind speed mode. The exhaust wind speed is the same. What's more, the exhaust air speed is greater than the supply air speed, which is the basic condition for achieving a negative pressure ward.

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

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 air exhaust device represented by the first range circle are not continuous. Therefore, in fact, the character range coordinates of the character 700 cannot directly correspond to the coordinates of the air supply device and the air exhaust device represented by the first range circle, and therefore, it must be redefined.

Next, please refer to FIG. 4A to FIG. 4E, which are a specific embodiment of using the character range coordinates of the character 700 to set the first range circle. Fig. 4A is the top-view projection space 901 of the protection space 1. It can be seen in the figure that the person 700 moves from the point P1 to the 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 captured image data is as shown in Fig. 4B, the person recognition system of the protection space 1 In the projection space 902 identified by 100, the person 700 is displayed as a person range 810-1 and a person range 810-2. The character recognition system 100 transmits the character range coordinates representing the character range 810-1 and the character range 810-2 to the wind farm control system 200. The wind field control system 200 can calculate the center coordinates of the character range 810-1 and the character range 810-2 according to the character range coordinates. Next, please refer to Figure 4C, the projection space 903 of the top-view air supply device in the protective space 1. After the wind field control system 200 converts the projection space to the projection space 903 of the air supply device, the character range 810-1 and the character range can be changed The character range coordinates of 810-2 are superimposed with the projection space 903 of the air supply device. Among them, the center coordinates of point P1 and point P2 are (X1, Y1) and (X2, Y1), respectively. Then, the wind farm control system 200 can follow The first range circle is defined according to the character range coordinates of the character range 810-1 and the character range 810-2.

There are many specific embodiments for the method of defining the first range circle of the present invention, for example, the method of defining center coordinates and the method of defining character range coordinates. Below, first introduce the method of defining the center coordinates, please refer to Figure 4D to Figure 4E. In Figure 4D, the wind farm control system 200 uses the calculated center coordinates (X1, Y1) of the point P1 to designate the central air supply device, which also corresponds to the designated central air exhaust device, that is, the central air supply device and the central exhaust air device. The device is the one that covers the coordinates of the point P1. However, this embodiment happens to be: the air supply device and the air exhaust device covering the center coordinates (X1, Y1) of the point P1 are one. However, in other cases, the center coordinates of the point P1 may be located at just two Between air supply devices, or between four air supply devices. Therefore, the center coordinate of the point P1 may substantially correspond to at least one central air supply device and central air exhaust device. The number of the central air supply device and the central exhaust device is affected by the structure of the air supply matrix and the exhaust air matrix. For example, Figure 4C is a square compact structure matrix, the maximum number of central air supply devices associated with point P1 is 4; Figure 4K is a square staggered matrix of air supply devices 340, and the maximum number of associated central air supply devices associated with point P1 is 3 Figure 4L shows the 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.

Returning to Figure 4D, the center coordinates (X1, Y1) correspond to an air supply device. The wind farm control system 200 defines it as the central air supply device 310-C0, and the nine air supply devices surrounding the central air supply device 310-C0 are The air supply device 310-C1 defined as the first range circle, the 14 air supply devices outside the air supply device 310-C1 surrounding 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, so I won't repeat it here.

In Figure 4E, the character 700 has moved to point P2, and its center coordinates (X2, Y1) It also corresponds to an air supply device. The wind farm control system 200 defines it as the central air supply device 310-C0, and the nine air supply devices surrounding the central air supply device 310-C0 are defined as the air supply device 310-C1 in the first range. , The 14 air supply devices outside the air supply device 310-C1 surrounding 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, so I won't repeat it here.

Define the center air supply device (more than one) as the center range circle, and after the first range circle, control the corresponding center air supply device, the wind speed of the first range air supply device is different from other wind speeds, for example, the center air supply device, The wind speed of the air supply device in the first range circle is lower than the wind speed of other air supply devices, which can cause a positive pressure in the space of the first range circle. On the contrary, it can cause negative pressure. Or, the wind speed of the central air supply device is the smallest, followed by the air supply device in the first range, and the wind speed of the other air supply devices is the largest; or vice versa. These controls are all executed by the control program of the wind farm control system 200. This is the control method of the embodiment shown in Fig. 4D and Fig. 4E.

In addition to controlling the wind speed of the central air supply device and the air supply device in the center range (the examples in Figures 4D and 4E), another way is to control the wind speed of other air supply devices that are not the center air supply device and the air supply device in the center range circle. , Make it smaller or greater than the wind speed of the central air supply device and the air supply device in the center range circle. Please refer to FIGS. 5A and 5B. In this embodiment, the center range circle is defined as all the air supply devices 310-C0 included in the person range coordinates of the person range 810-1. There are 9 air supply devices in the legend. The air supply device is surrounded by the air supply device 310-C1 in the first range circle, a total of 24; the air supply device 310-C2 in the second range circle outside the first range circle is surrounded; The air supply device 310-C3 of the range circle, and so on. Control the air supply device of the first range circle, the second range circle, and the third range circle to make the wind speed different from the air supply device of the center range circle. Similarly, when the wind speed in the center range is the smallest, it can make the space The range produces positive pressure, and vice versa, negative pressure.

Regardless of the method, the present invention can define the first range circle, the center range circle, etc. by the character range coordinates, and then use the center range circle or the wind speed in the first range circle to be different from others, so as to achieve the local space. The special technical effect of positive pressure or partial negative pressure. Conceptually, whether it is the center range circle or the first range circle that covers the range coordinates of the character, the new model is based on the corresponding air supply device covering the range coordinates of the character to generate positive or negative pressure in the space where the character is located. .

In the embodiment of Fig. 4D and Fig. 4E, the size of the first range circle can cover the character range 810-1 and the character range 810-2. This is an example where the size of the air supply device is 20 cm (cm) x 20 cm (cm). The size of the three air supply devices is 60 cm, and the shoulder width of a typical person is about 40-50 cm. If the size of the air blowing device is larger or smaller, the number of projection planes of the air blowing device corresponding to the person range 810-1 and the person range 810-2 may be different. In Figure 4F, the size of the air supply device 310 is 20 cm x 20 cm, and the figure 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 figure 700 can be 4 to 9 Covered by the air supply device; Figure 4H, the size of the air supply device 312 is 40 cm x 40 cm, and the figure 700 can be covered by 2 to 6 air supply devices; Figure 4I, the size of the air supply device 313 is 60 cm x 60 cm, the figure 700 can be covered by 1~4 air supply devices.

The method of defining the first range circle with the center coordinates is applicable when the size of the air supply device is small. However, the larger the size of the air supply device, it may cause the first range circle to be too large. For example, in the embodiment of Figure 4H, the first range circle may cover 12 air supply devices, and its range covers 240 cm x 240 Centimeters do not meet actual needs. Therefore, Figure 4J of this new model adopts another method, in a 40 cm x 40 cm air supply device 370, equipped with Set 4 air outlets, making it into an actual air outlet of 20 cm x 20 cm.

The above embodiment of the air supply device is a technology of a full-covered air supply device, that is, the air supply opening (or air supply opening) of the air supply device is a way of blowing out the whole area. In other words, the air blowing device blows air at a time with an area of square M cm x M cm, and the wind speed sent by this area is the same.

Please refer to FIG. 7A to FIG. 7E for an embodiment of the method for defining the shape, function block diagram and the first range circle of the square peripheral air blowing device 350 of the present invention. The peripheral air supply device 350 includes four air supply ports 350g-1, air supply ports 350g-2, air supply ports 350g-3, and air supply ports 350g-1. The air outlet 350g-1, the air outlet 350g-2, the air outlet 350g-3, and the air outlet 350g-1 are individually arranged on the periphery of the peripheral air blowing device 350 facing the protective space 1, as shown in Fig. 7A.

Please refer to Figure 7B. The peripheral air blowing device 350 includes: an air inlet 350c connected to the ventilation duct 500; a fan 350d facing the air inlet 350c; a motor 350a drives the fan 350d. (Wind 650) Brought in: four air doors 350e-1, air door 350e-2, air door 350e-3, and air door 350e-4 are set at the outlet of fan 350d to control the air output of fan 350d; four screens The net 350f-1, the screen 350f-2, the screen 350f-3, and the screen 350f-4 are respectively set at the air outlet of the air door 350e-1, air door 350e-2, air door 350e-3, and air door 350e-4, To homogenize the air output of the air door 350e-1, air door 350e-2, air door 350e-3, and air door 350e-4; four air outlets 350g-1, air outlets 350g-2, air outlets 350g-3, air outlets 350g -4, each set at the outlet of screen 350f-1, screen 350f-2, screen 350f-3, screen 350f-4 and facing the protective space 1; controller 350b, connected to motor 350a and damper 3503.

The structure of the four-in-one peripheral air exhaust device can be the same as the four-in-one peripheral air supply device, that is, it adopts multiple air inlets and multiple dampers. 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/closed or adjustable opening ratio type. Microcontroller 350b received from the wind farm control system 200 After the wind farm control command, control the motor 370a and the damper 370e-1, damper 350e-2, damper 350e-3, damper 350e-4 to make the air outlet 350g-1, air outlet 350g-2, air outlet 350g-3, air outlet The wind 611-1, wind 611-1, wind 611-1, and wind 611-1 of the mouth 350g-4 may be different.

Next, please refer to Figure 7D and Figure 7E. When the center point A of the character's range coordinates is moved to the center point B, the wind field control system 200 corresponds to the center range circle 350-C0 and the first range circle 350 -C1 moves, the center range circle moves from the air supply device 350N-M to the air supply device 350-(N+1)-(M+1).

Next, please refer to FIGS. 8A to 8D, the shape of the hexagonal peripheral air blowing device 360 of the present invention and the embodiment of the method for defining the first range circle. Compared with the embodiment shown in Figure 7A to Figure 7E, the difference between the two is the number of air supply openings. The 8A hexagonal peripheral air supply device 360 has six air supply openings, which are divided into: air supply opening 360g-1 , Air outlet 360g-2, air outlet 360g-3, air outlet 360g-4, air outlet 360g-5, air outlet 360g-6, the side facing the protective space, specifically arranged in a honeycomb shape as shown in Figure 8B. In Fig. 8C and Fig. 8D, when the center point A of the character range coordinates is moved to the center point B, the wind field control system 200 corresponds to the center range circle 360-C0 and the first range circle 360-C1 Move, the center range circle moves from the air blowing device 360N-M to the air blowing device 350-(N-1)-(M+1).

It can be seen from the above description that the present invention uses the wind farm control system 200 to control the matrix wind generation system. According to the character range coordinates of the character recognition system 100, the character 700 is realized by defining the first range circle or the center range circle. The positive or negative pressure of the space. Hereinafter, several examples of control methods will be listed to illustrate the new positive and negative pressure generation and control method.

First of all, please refer to Figures 9A to 9C. In the first embodiment of the present invention, the full-cover method for generating a protective air pressure difference, the main process includes the following steps:

Step S101: Perform person recognition by the person recognition system. When a person is detected, a person range coordinate is generated, and the person range coordinate is defined according to the projection coordinates of the protection space.

Step S102: Define the individual projection coordinates of the air supply devices and the air exhaust devices in the protective space.

Step S103: According to the character range coordinates, define the air supply devices and the air exhaust devices corresponding to the character range coordinates as a first range circle, so that the air supply devices and the exhaust air devices in the first range circle The wind speed generated by the device is different from the wind speeds generated by the air supply devices and the air exhaust devices other than the first range circle, thereby forming a first pressure difference range circle.

The process in Figure 9A has two main technical features: defining the first range circle by the character range coordinates, and controlling the difference in wind speed between the first range circle and 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 character range coordinates, the present model provides some specific embodiments:

The flow in Fig. 9B provides an example of defining the first range circle: the air supply device passing through the range coordinates of the character is taken as the first range circle. That is, the coordinates of the character range are the boundary coordinates of the character range, and all air supply devices or exhaust devices that cover this boundary are those in the first range. The embodiment of Figure 9B includes the following steps:

Step S111: The air supply devices and the air exhaust devices passing through the range coordinates of the person are defined as the first range circle.

Step S112: Check whether there are still undefined air supply devices and air exhaust devices in the space enclosed by the first range circle, and if so, define it as a central range circle. Taking the example of Fig. 4F as an example, the character 700 may be covered by 6 to 12 air supply devices, and the outermost circle The approximate is 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 the center range circle may be 0, 1, or 2. Therefore, when the first range circle is defined in the manner of this embodiment, there may be no center range circle in some situations.

Step S113: Make the wind speeds generated by the central range circle, the air supply devices of the first range circle, the exhaust devices and the non-central range circle, the air supply devices and the exhaust air of the first range circle The wind speed generated by the device is different, and then a first pressure difference range circle is formed.

The first pressure difference range circle can be positive pressure or negative pressure, depending on the application scenario. Take the negative pressure ward as an example. To protect medical staff, provide a positive pressure environment for medical staff and provide a negative pressure environment for patients. In contrast, the second pressure difference range circle is the opposite of the first pressure difference range circle.

Among them, when there is no center 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. Adjust the positive pressure in the first range circle: I. By adjusting the supply air speed and exhaust air speed of the air supply devices and the exhaust air devices in the first range circle to be lower than the initial setting value, other air supply devices and exhaust air The wind speed of the device is the initial set value; II. By adjusting the air supply and exhaust wind speeds of the air supply devices and the exhaust air devices outside the first range circle to be greater than the initial set value. Adjust the negative pressure in the first range circle: I. By adjusting the air supply and exhaust wind speeds of the air supply devices and exhaust devices in the first range circle to be greater than the initial setting value; II. By adjusting the non-first range The air supply wind speed and the exhaust air speed of the air supply devices and the air exhaust devices in a range circle are less than the initial setting value, and the first range circle is the initial setting value. One of the above two methods is to adjust the wind speed in the first range circle, and the other is to adjust the wind speed in the non-first range circle. The adjustment objects of the two are different, but the technical effects obtained are the same.

When there is a center range circle, this model provides several kinds of control in the first range circle The air supply device generates positive pressure, that is, the embodiment of adjusting the blowing wind speed and the exhaust wind speed. Adjust the positive pressure in the first range circle: I. By adjusting the center range circle, the air supply devices and the exhaust devices in the first range circle, the air supply and exhaust air speeds are less than the initial setting value, and other The wind speed of the air supply device and the exhaust device is the initial setting value, and the wind speed of the center range circle is lower than the first range circle, that is, the wind speed of the center range circle is the smallest. Adjust the negative pressure in the first range circle: I. By adjusting the center range circle, the air supply devices, and the exhaust devices in the first range circle, the air supply and exhaust air speeds are greater than the initial set value, and the center The wind speed of the part of the scope circle is greater than that of the first scope circle, that is, the wind speed of the center scope circle is the highest. One of the above two methods is to adjust the wind speed in the first range circle, and the other is to adjust the wind speed in the non-first range circle. The adjustment objects of the two are different, but the technical effects obtained are the same.

The process in Fig. 9C provides another embodiment of defining the first range circle: the first range circle is defined by the center coordinates. That is, the center coordinates calculated from the range coordinates of the characters define the range of the first range circle. The embodiment of Figure 9C includes the following steps:

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

Step S122: According to the center coordinate, select at least one of the air supply device and at least one of the exhaust device closest to the center coordinate as a center range circle. As mentioned above, the number of air supply devices in the center range circle, taking Figure 4F as an example, may be 1, 2, or 4. According to the embodiment of 4K and 4L, there may be one, two, or three.

Step S123: Define the air supply devices and the air exhaust devices covering the center range circle as a first range circle, and check whether the range covered by the first range circle completely covers the person's range coordinates.

Step S124: If the range covered by the first range circle does not completely cover the person For the object range coordinates, at least one of the air supply device and the exhaust device that can cover the range coordinates of the character is selected to the first range circle.

Step S125: Make the wind speeds generated by the central range circle, the air supply devices of the first range circle, the exhaust devices and the non-central range circle, the air supply devices of the first range circle, and the exhaust air The wind speed generated by the device is different, and then a first pressure difference range circle is formed.

Comparing the embodiments in FIG. 9B and FIG. 9C, it can be seen that the first range circle defined by the two may be the same or different. In the embodiment of Fig. 9B, there may be no center range circle, while in the embodiment of Fig. 9C, there must be a center range circle. Therefore, the definition method of the first range circle is different, it may lead to the same range of the first range circle, or it may be different. Once the center range circle and the first range circle are defined, the method of generating positive pressure and negative pressure is the same as described above, so I won't repeat it here.

The above wind farm control method is a control method when a full-covered air supply device and a full-covered exhaust device are used as examples. Hereinafter, the control method of the peripheral air blowing device and the exhaust air device will be described. Please refer to Figure 10A to Figure 10C, the peripheral method to generate a protective air pressure difference, the main process includes the following steps:

Step S201: Perform person recognition by the person recognition system. When a person is detected, a person range coordinate is generated, and the person range coordinate is defined according to the projection coordinates of the protection space.

Step S202: Define individual projection coordinates of the air outlets of the air supply devices and the air outlets of the air exhaust devices in the protective space.

Step S203: Calculate one of the center coordinates of the person's range coordinates. Different from the full-covered air supply device, the air outlet of the peripheral air supply device is located on the periphery, while the full-covered air supply device The installed air outlet is the whole surface. Therefore, the center of the air outlet of the peripheral air supply device is located at the center of each side, and the center of the air outlet of the full-covered air supply device is located at the center of the entire surface. Therefore, when the person's range coordinates pass through a peripheral air supply device, it is possible to pass only one, two or three air supply openings. It is difficult to determine whether the passing position is inside or outside. Therefore, by using the center coordinates of the character range coordinates as a reference point, the relationship between the air outlet of the peripheral air supply device and the character range coordinates can be more accurately grasped.

Step S204: Define the air outlets of the air supply devices and the air outlets of the air exhaust devices corresponding to the person range coordinates as a first range circle according to the character range coordinates, so that the first range circle The wind speed generated by the air outlets of all the air supply devices and the air outlets of the air exhaust devices and the air outlets and the air exhaust devices of the air supply devices outside the first range circle The wind speeds generated by the air outlets are different, and then a first pressure difference range circle is formed.

An example of defining the first range circle is shown in Figure 10B.

Step S211: According to the range coordinates of the person, select the air outlets of the air supply devices and the air outlets of the air exhaust devices that are greater than and closest to the distance between the range coordinates of the person and the center coordinate as one The first range circle, and the air outlets of the first range circle can surround the character range coordinates. Different from the full-covered air supply device, since the full-covered air supply device can "cover" the character coordinate range, forming a closed structure; while the peripheral air supply device has the air supply opening on the periphery, so the air supply through the character coordinate range Mouths may appear open to each other, yes, but not connected to each other. Therefore, one of the embodiments of the present invention is to form a closed closed structure connected to each other by the air supply openings.

Step S212: Make all the air supply devices in the first range circle The wind speeds generated by the air supply outlets and the air outlets of the air exhaust devices are less than the wind speeds generated by the air outlets of the air supply devices and the air outlets of the air exhaust devices that are not in the first range circle, In turn, a positive pressure difference range circle is formed.

Step S213: Make the wind speeds generated by the air outlets of all the air supply devices and the air outlets of the air exhaust devices in the first range circle greater than that of the air supply devices that are not in the first range circle The wind speeds generated by the air outlets and the air outlets of the air exhaust devices form a negative pressure differential range circle.

Another example of defining the first range circle is shown in Figure 10C.

Step S221: Select the air outlets of the air supply devices and the air outlets of the air exhaust devices corresponding to the person range coordinates as a first range circle according to the character range coordinates.

Step S222: Make the wind speeds generated by the air outlets of all the air supply devices and the air outlets of the air exhaust devices in the first range circle be lower than that of the air supply devices that are not in the first range circle. The wind speed generated by the air outlets and the air outlets of the air exhaust devices forms a positive pressure difference range circle.

Step S223: Make the wind speeds generated by the air outlets of all the air supply devices and the air outlets of the air exhaust devices in the first range circle greater than that of the air supply devices that are not in the first range circle The wind speeds generated by the air outlets and the air outlets of the air exhaust devices form a negative pressure differential range circle.

Both steps S211 to S213 and steps S221 to S223 are methods of defining the first range circle. In addition, you can further define the center range circle, as shown in Figure 10D.

Step S231: Define the air supply devices of the air supply devices surrounding the center coordinate The air outlets and the air outlets of the air exhaust devices form a central range circle. As in the aforementioned embodiment, the center range circle here is based on the concept of enclosing, similar to step S211 to step S213. Since the center coordinate is a point, it may be located at the air outlet of the peripheral air supply device, or it may be located outside the air outlet. Taking the embodiment in Figure 4F as an example, if it is just located at the air supply opening, the number of air supply openings of the peripheral air supply device surrounding the center coordinate may be five, that is, the adjacent air supply opening and the surrounding air supply The four air supply openings of the device itself; it can also be one, that is, the air supply opening. If the center coordinate is just between two air supply openings, then the number of air supply openings of the peripheral air supply device surrounding the center coordinate is eight (closed enclosure), or two (open enclosure) can be used. If the center coordinates are located exactly between the four air supply openings, then the number of air supply openings of the peripheral sealing device surrounding the center coordinates is four. So on and so forth. The concept of envelopment here can not only be interpreted by the concept of closed envelopment from step S111 to step S113, but also by the concept of open envelopment. .

Step S232: Make the wind speeds generated by the air outlets of all the air supply devices and the air outlets of the air exhaust devices in the first range circle be lower than that of the air supply devices not in the first range circle The wind speeds generated by the air outlets and the air outlets of the air exhaust devices, and the air outlets of all the air supply devices and the air outlets of the air exhaust devices in the center range are generated The wind speed is lower than the wind speed generated by the air outlets of the air supply devices and the air outlets of the air exhaust devices of the first range circle, thereby forming a positive pressure difference range circle.

Step S233: Make the wind speeds generated by the air outlets of all the air supply devices and the air outlets of the air exhaust devices in the first range circle greater than that of the air supply devices that are not in the first range circle The wind speeds generated by the air outlets and the air outlets of the air exhaust devices, and make the air outlets of all the air outlets and the air exhaust devices in the center range circle The wind speed generated by the air outlets is greater than the wind speeds generated by the air outlets of the air supply devices and the air outlets of the air exhaust devices of the first range circle, thereby forming a negative pressure difference range ring.

In the embodiment from step S231 to step S233, the purpose is also to create wind speeds at different layers, such as the center range circle, the first range circle, etc., in order to reach the first range circle, or from the center range circle to the first range circle to others The state of increasing or decreasing wind speed of the part.

Similarly, step S231 to step S233 can also be used to control the air outlet outside the first range circle so that its speed is different from the wind speed of the air outlet within the first range circle. The method is as mentioned before, so I won't repeat it here.

However, after a person is detected, who is it to be judged? Whether it is a medical staff or a patient, only then will I know how to protect the person from the differential pressure. Hereinafter, several embodiments will be cited for description.

In an 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, the concept of either black or white. The specific method is as follows: when the identified person has a label, the first differential pressure range circle is formed; when the identified person does not have the label, based on the character's range coordinates, select the one that passes through the character's range coordinates The air supply devices and the air exhaust devices are a first range circle, so that the wind speeds generated by the air supply devices and the exhaust devices in the first range circle are different from the air supply devices outside the first range circle , The wind speeds generated by the exhaust devices are different, thereby forming a second pressure difference range circle, which is opposite to the first pressure difference range circle.

Then, in another embodiment of the present invention, a double labeling method is adopted. That is, when the recognized person has a first label, the first pressure difference range circle is formed; when the recognized person has a second label, a second pressure difference range circle is formed, and the second pressure difference Fan The ring is opposite to the first pressure difference range ring.

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

It can be seen from the above various embodiments that the present invention is created by realizing the character recognition of the character 700, the definition of the range where the character is located (the first range circle), and the generation of different wind speeds, resulting in different wind pressures around the character. A protective wind pressure space realizes active protection for medical staff or other persons in need of protection. This active protection is equivalent to an air shield, and it moves with the side of the medical staff. Therefore, the implementation of the new technology allows medical staff to add a protective net to medical staff when modern negative pressure wards are still defective, so as to reduce the possibility of medical staff being infected.

Although the technical content of the present invention has been disclosed in a preferred embodiment as above, it is not intended to limit the present invention. Anyone who is familiar with this technique, who does not deviate from the spirit of the present invention, makes some changes and modifications, shall be covered by the present invention.
