FIG. 2 is an enlarged view of a differential pressure module area of FIG. 2, and FIG. 5 is a control block diagram of a system for preventing bacteria contamination in a bio-clean room using the artificial intelligent air pressure differential device according to an embodiment of the present invention.

Referring to these drawings, a bacterial contamination prevention system of a bio-clean room using an artificial intelligent air pressure differential apparatus according to an embodiment of the present invention includes an air pollution sensor (not shown) provided in an isolation chamber 100 to detect air contamination in the isolation chamber 100, An inlet pipe 110 connected to one side of the isolation chamber 100 and supplying air to the isolation chamber 100 and a discharge pipe 110 connected to the other side of the isolation chamber 100 and discharging air in the isolation chamber 100 A differential pressure sensor 129 installed in an area of the discharge pipe 120 for sensing air pressure in the isolation chamber 100 and a differential pressure module installed in the discharge pipe 120 for controlling air pressure in the isolation chamber 100 And a controller 140 for controlling the operation of the differential pressure module 130 based on the information from the air pollution sensor 115 and the differential pressure sensor 129. [

1, an inflow pipe 110 for supplying air to the isolation chamber 100 is installed, a discharge pipe 120 is installed at a predetermined distance from the inflow pipe 110, A controller 140 and an air pollution sensor 115 are installed on the side wall.

The inflow pipe 110 is provided with a clean filter 111 for purifying air that is forcedly blown through the inflow pipe 110. The purge filter 121 is provided in the discharge pipe 120 to filter the contaminated air so that the contaminated air in the chamber 100 is not discharged to the outside.

The inflow tube is provided with a UV irradiator 118 and an anion generator 119. The intensity and operation of the UV irradiator 118 and the negative ion generator 119 can be controlled by the controller 140.

The UV irradiator 118 is provided in the inflow pipe 110 and serves to sterilize the air supplied to the isolation chamber 100 through the inflow pipe 110 by irradiating ultraviolet rays. The air filtered by the clean filter 111 can be sterilized by irradiating ultraviolet rays (UV), and clean clean air can be supplied to the isolation chamber 100.

These UV irradiators 118 are arranged opposite to each other on both sides of the inflow pipe 110. Therefore, the UV irradiation efficiency can be improved.

The negative ion generator 119 is disposed around the UV irradiator 118 in the inflow pipe 110 and serves to generate negative ions in the air supplied to the isolation chamber 100 through the inflow pipe 110. When the negative ion generator 119 is applied, the sterilization effect by the negative ions helps to supply clean air to the separation chamber 100.

As described above, in the present embodiment, the UV tube 118 and the negative ion generator 119 are provided in the inflow tube to cleanly control the air. The negative ion generator 119 is connected to the UV irradiator 118 so that the efficiency is increased.

At an end of the inflow pipe 110, an inflow guide 112 for guiding air in the inflow pipe 110 into the isolation chamber 100 is installed.

At the end of the discharge pipe 120, an inclined discharge guide 122 for guiding the air in the discharge chamber 120 into the discharge pipe 120 is installed.

At this time, vortex prevention dummy guides 112a and 122a are further formed inside the inclined guide 112 and the inclined guide 122.

The vortex-suppressing dummy guides 112a and 122a may be disposed in an inner central region of the inclined inlet guide 112 and the inclined outlet guide 122.

This structure allows air to flow smoothly into the chamber 100 when the air enters the chamber 100 from the tapered inlet guide 112 and also when the air in the chamber 100 is discharged to the tapered outlet guide 122. [ Circulation becomes possible.

In the region of the discharge pipe 120, a differential pressure module 130 for regulating the air pressure in the isolation chamber 100 is provided.

A blowing fan 125 for quickly discharging the air inside the isolation chamber 100 may be installed behind the differential pressure module 130. If the discharge fan (not shown) installed for forcibly discharging the air in the isolation chamber 100 is stopped or fails at the rear end of the discharge pipe 120, The pressure of the separating chamber 100 is increased and the pressure of the inside of the separating chamber 100 is reduced so that the blowing fan 125 is not formed so that the pressure inside the separating chamber 100 is formed only by the positive pressure (the internal pressure of the separating chamber 100> . Therefore, the blowing fan 125 does not normally operate.

A purifying filter 121 is provided at the rear of the blowing fan 125 to filter the polluted air so that contaminated air in the isolation chamber 100 is not discharged to the outside.

On the other hand, the differential pressure module 130 is installed in the region of the discharge pipe 120 and controls the air pressure difference in the isolation chamber 100 through a different structure, for example, a rotating shutter 132 structure.

The differential pressure module 130 includes a shutter support 131 installed in the discharge tube 120 and having a plurality of air holes 131a and a plurality of shutters 132 rotatably connected to the shutter support 131 And a shutter driving unit 133 for driving the shutter 132. [ The shutter driving unit 133 may include, for example, a motor, and plays a role to drive a plurality of shutters 132 together.

On the other hand, the controller 140 controls the operation of the differential pressure module 130, that is, the operation of the shutter drive unit 133, based on the information from the air pollution sensor 115 and the differential pressure sensor 129.

That is, the user can check the internal pressure or contamination state of the isolation chamber 100 through the controller 140 through the data input from the air pollution sensor 115 or the differential pressure sensor 129, To control the differential pressure module 130. [ The control can be either automatic or manual.

The controller 140 performing such a role may include a central processing unit 141, a memory 142, and a support circuit 143, as shown in FIG.

The central processing unit 141 can be used to control the operation of the differential pressure module 130 based on the information from the air pollution sensor 115 and the differential pressure sensor 129 in this embodiment among various computer processors It can be one.

The memory 142 (MEMORY) is connected to the central processing unit 141. The memory 142 may be a computer-readable recording medium and may be located locally or remotely and may be any of various types of storage devices, such as random access memory (RAM), ROM, floppy disk, hard disk, At least one or more memories.

The support circuit 143 (SUPPORT CIRCUIT) is coupled with the central processing unit 141 to support the typical operation of the processor. Such a support circuit 143 may include a cache, a power supply, a clock circuit, an input / output circuit, a subsystem, and the like.

The controller 140 controls the operation of the shutter driving unit 133 of the differential pressure module 130 based on the information from the air pollution sensor 115 and the differential pressure sensor 129 in this embodiment. At this time, a series of processes or the like in which the controller 140 controls the operation of the differential pressure module 130 based on the information from the air pollution sensor 115 and the differential pressure sensor 129 may be stored in the memory 142.

Typically, a software routine may be stored in the memory 142. The software routines may also be stored or executed by other central processing units (not shown).

Although processes according to the present invention are described as being performed by software routines, it is also possible that at least some of the processes of the present invention may be performed by hardware.

As such, the processes of the present invention may be implemented in software executed on a computer system, or in hardware such as an integrated circuit, or in combination of software and hardware.

Hereinafter, the operation of the system for preventing bacterial contamination of the bio-clean room using the artificial intelligent air pressure differential device according to the present invention will be described.

First, the external air supplied through the inflow pipe 110 passes through a clean filter 111 formed in the inflow pipe 110, is purified through the UV irradiator 118 and the negative ion generator 119 to be converted into clean air , Clean air is supplied into the interior of the isolation chamber (100).

Even if the clean air is continuously supplied to the patients accommodated in the isolation chamber 100, the inside air of the isolation chamber 100 is slightly contaminated due to the breathing of the patients or the exposed portion of the virus.

A positive pressure is generated in the interior of the isolation chamber 100 due to the air continuously supplied to the isolation chamber 100 through the inflow pipe 110 so that the contaminated air leaks through the gap 116 of the isolation chamber 100 (Internal pressure of the isolation chamber 100, external pressure of the isolation chamber 100), sound pressure (internal pressure of the isolation chamber 100, external pressure of the isolation chamber 100), internal pressure of the isolation chamber 100, , And a positive pressure (the inner pressure of the separation chamber 100 = the outer pressure of the separation chamber 100).

Here, in case of a patient suffering from respiratory disease, it is preferable to maintain the inside of the isolation chamber 100 at a constant pressure. This is because a patient with respiratory disease is caused to leak the virus into the air through the respiration, and the air mixed with the virus is leaked to the outside through the gap 116 of the isolation chamber 100, This is because the air may be introduced and the condition of the patient may deteriorate.

The differential pressure sensor 129 reads the internal pressure of the isolation chamber 100 and transmits the internal pressure to the controller 140 so as to form a static pressure inside the isolation chamber 100. The controller 140 reads the data read from the differential pressure sensor 129 2, when the pressure is low, the shutter 132 drives the shutters 132 of the differential pressure module 130 to reduce the opening of the air vent 131a to form a constant pressure inside the chamber 100, The positive pressure causes the shutters 132 to enlarge the opening of the air vent 131a so that the inside of the chamber 100 can be formed with a positive pressure. The controller 140 reads the internal pressure of the differential pressure sensor 129 at a predetermined time interval even if the internal pressure of the isolation chamber 100 is changed and the shutter drive unit 133 of the differential pressure module 130 automatically It is possible to maintain the constant pressure at all times.

On the other hand, in the case of an infectious disease, the interior of the isolation chamber 100 must be formed with a negative pressure or a constant pressure. In the case of infectious disease, it is not a big problem if the outside air is inflowed. However, if the virus of infectious disease leaks to the outside, it is necessary to form a negative pressure or a static pressure in the isolation chamber 100 because other people are infected with virus and suffer serious damage .

The controller 140 drives the shutter driving unit 133 of the differential pressure module 130 based on the data read by the differential pressure sensor 129 so that the interior of the isolation chamber 100 is maintained at a negative pressure or a positive pressure.

4, when the general patient is accommodated in the isolation chamber 100, the air pollution sensor 115 measures the degree of contamination inside the isolation chamber 100. If the contamination level is increased beyond a predetermined level, the controller 140 The air blowing fan 125 is operated to cause the shutters 132 of the differential pressure module 130 to open the air vent holes 131a to the maximum to rapidly discharge the air inside the chamber 100, The air blowing fan 125 of the differential pressure module 130 is stopped and the air vent holes 131a of the differential pressure module 130 are opened only to a predetermined extent to allow the interior of the isolation chamber 100 to maintain a positive pressure, It is only necessary to prevent the patient from being contaminated.

As described above, the air blowing fan 125 is used only for the purpose of rapidly discharging contaminated air in the isolation chamber 100, and is not normally used.

The differential pressure sensor 129 may be installed in the isolation chamber 100 as many times as necessary so that the average pressure of the isolation chamber 100 can be known in detail because the internal pressure difference of the isolation chamber 100 is different depending on the position.

The controller 140 installed in the isolation chamber 100 of the present invention is connected to a central server through an external network to check the state of each of the sickrooms in a central control room having a central server, And it is also possible to check whether the controller 140 installed in the isolation chamber 100 and the devices connected to the controller 140 are abnormal.

In addition, it is possible to manage the sickness of various hospitals in the central control room, and in case of an abnormality in the equipment, the central control room can notify each hospital staff of the abnormality of the apparatus, dispatch the maintenance article, and immediately respond.

As described above, according to the present embodiment, by effectively controlling the air inside and outside the isolation chamber 100, it is possible to prevent deterioration of the patient's condition and to maintain a healthy and comfortable isolation chamber.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Accordingly, such modifications or variations are intended to fall within the scope of the appended claims.
