It should be understood that it is included in the technical spirit of the present invention.

Meanwhile, according to one aspect of the present invention, the controller 1200 may be configured to control the mobile sterilization device 1700 based on whether or not a human body is present in the toilet or the living space.

For example, the controller 1200 may be configured to stop the movement of the mobile sterilization device 1700 in response to the sensor unit 1100 detecting a human body. Some of the toilet users may have objection to the movement of the mobile sterilization device 1700 while using the toilet. Accordingly, the controller 1200 may stop the movement of the mobile sterilization device 1700 in response to detecting that a human body exists inside the bathroom. When the human body does not exist, the movement of the mobile sterilization device 1700 may be started again. Alternatively, as previously mentioned with reference to FIG. 8 , the presence of a user in the occupied space is detected, and when the user is present in the occupied space, the mobile sterilization device 1700 is controlled not to move to the occupied space, so that the open space However, the mobile sterilization device 1700 may be configured to perform sterilization while continuously moving in an occupied space where a user is not located.

According to one aspect, the control unit 1200 stops the operation of the surface sterilization unit 1010 in response to the sensor unit 1100 detecting a human body, and the air sterilization unit 1020 stops the operation of the human body regardless of whether or not the human body is detected. It can also be controlled to operate. That is, the surface sterilization unit 1010 may be configured to irradiate the surface with ultraviolet rays, which may affect the human body or cause discomfort to the user. Accordingly, when the controller 1200 detects the presence of a human body, the operation of the surface sterilization unit 1010 can be stopped to minimize the effect on the human body and/or cause discomfort. On the other hand, since the air sterilization unit 1020 may be configured to irradiate ultraviolet rays to the photocatalyst present therein, it may not directly affect the human body. Accordingly, the controller 1200 can control the air sterilization unit 1020 to operate regardless of whether or not a human body is detected.

As described above, the toilet comprehensive sterilization management system according to one aspect of the present invention is provided with a mobile sterilization device 1700, so that a sterilization effect for a large area can be expected while using a small amount of sterilization device, thereby reducing cost and sterilization Simultaneous improvement of effect can be achieved.

FIG. 11 is an exemplary view of the toilet comprehensive sterilization management system of FIG. 10 . As shown in FIG. 11, for example, the toilet comprehensive sterilization management system (1000b) having a main sterilization device and an occupied room sterilization device according to an embodiment of the present invention includes a first main sterilization device (1800-1) and a second sterilization device (1800-1). At least one main sterilization device 1800 may be provided, such as 2 main sterilization devices 1800-2, and a first room sterilization device 1900-1, a second room sterilization device 1900-2, and a third room sterilization device 1900-2.

As shown in FIG. 12 , the main sterilization device 1800 according to an embodiment of the present invention may include a surface sterilization unit 1010a, an air sterilization unit 1020a, and a detection sensor 1103. That is, the main sterilization device 1800 can be configured to perform air sterilization and surface sterilization.

More specifically, but not exclusively, the main sterilization device 1800 includes, for example, an ultraviolet LED to perform surface sterilization and a photocatalytic filter (eg, a ceramic titanium oxide coating) and an ultraviolet LED for photocatalytic reaction. It is possible to perform air sterilization by reacting a photocatalyst. For example, power may be supplied by a 12 V adapter, but is not limited thereto.

The main sterilization device (1800) implements a two-stage air purification system suitable for multi-use facilities that removes ultra-fine dust, harmful odors, viruses and bacteria by combining a photocatalyst filter and ultraviolet LED sterilization technology to improve indoor air quality and provide fresh air It may be configured to supply. For example, active oxygen generated by the photocatalytic filter decomposes not only acetaldehyde, which is a carcinogen, but also ammonia and toluene, which are causes of various odors, so that a deodorizing effect of removing various odors can be expected.

In addition, active oxygen generated by the photocatalytic filter can change metals and sulfates, which are volatile organic compounds that cause fine dust, into water and carbon dioxide to suppress generation, thereby removing harmful substances harmful to the human body. Therefore, the effect of removing fine dust can be expected. On the other hand, the effect of removing viruses and bacteria can also be expected by preventing proliferation and reproduction by destroying DNA proteins and nucleic acids of microorganisms by ultraviolet LED.

That is, indoor odor removal, fine dust removal, and indoor air sterilization may be performed, and a temperature measurement sensor and/or humidity measurement sensor may be provided to additionally measure indoor temperature and humidity.

A detection sensor 1840 is provided in the main sterilization device 1800 to detect whether a human body is detected around the main sterilization device 1800. Meanwhile, the operation indicator lamp 1850 may be configured to be turned on in conjunction with the turn-on of the UV lamp 1840 . Since UV rays are non-visible rays, the user cannot check whether they are operating or not. Therefore, by providing an operation indicator lamp 1850 so that visible rays are emitted when the UV lamp is operating, the user can confirm whether or not UV rays are being irradiated. .

For example, UV LEDs can sterilize interior surfaces (partitions, floors, toilets, sinks, etc.), and air sterilization and deodorization can be performed with a photocatalytic system. Based on the human body detection sensor, safety can be guaranteed by sterilization operation in the absence of the user. For example, the air sterilization unit may be configured to always operate regardless of the presence or absence of a user. Illustratively, the supply of electricity may be connected to a power source of an interior light so as to be operated in conjunction with the interior light. In addition, data such as sterilization time, indoor temperature, and indoor humidity may be measured and transmitted to the controller in real time. Related information may be displayed through the display unit. For example, the display unit may be implemented as a monitor installed at the entrance of a bathroom.

In more detail, but not limitedly, the room sterilization device 1900 may perform sterilization of the inner surfaces of individual rooms (partitions, floors, toilets, handles, etc.) with UV LEDs. For example, the user's occupancy state can be confirmed by the operation of the human body detection sensor, and safety can be guaranteed by sterilization operation in the absence of the user by the human body detection sensor. Meanwhile, if the user's occupancy time is measured and the user does not move for a predetermined period of time or longer, the user's situation may be transmitted to the control unit in real time, so that an emergency situation may be warned or notified.

17 is a perspective view of an exemplary room sterilization device. As exemplarily shown in FIG. 17 , the room sterilization apparatus 1900 may perform surface sterilization by including an ultraviolet lamp 1920 for surface sterilization. A detection sensor 1910 is provided in the room sterilization device 1900 to detect whether a human body is detected around the room sterilization device 1900. Meanwhile, the operation indicator lamp 1930 may be configured to be turned on in conjunction with the turn-on of the UV lamp 1920 . Since ultraviolet rays are non-visible rays, the user cannot confirm whether or not they are operating, so the operation indicator lamp 1930 is provided so that visible rays are emitted when the ultraviolet lamp is operated, so that the user can confirm whether or not the ultraviolet rays are being irradiated. .

Meanwhile, in the present description, the detection sensor 1101, the detection sensor 1102, and the detection sensor 1103 may be referred to as a first detection sensor, a second detection sensor, and a third detection sensor, respectively. According to one aspect of the present invention, the detection sensor unit 1100 may include a first detection sensor 1101 , a second detection sensor 1102 , and a third detection sensor 1103 . For example, the first detection sensor 1101 is applied to toilet paper dispensers 30-1, 30-2, and 30-3 disposed in each of at least one occupied space 20-1, 20-2, and 20-3. The second detection sensor 1102 may be integrally installed in the room sterilization device 1900, and the third detection sensor 1103 may be integrally installed in the main sterilization device 1800. In addition, the detection sensor unit 1100 may include various detection sensors disposed in a specific location of the toilet or part of the system configuration.

According to one embodiment, the detection sensor unit 1100 of the present invention includes a first detection sensor 1101 installed in a dispenser, a second detection sensor 1102 integrated in an occupied sterilization device, and a third integrally installed in a main sterilization device. A detection sensor 1103 may be included, and the sterilization device may be controlled based on at least one of the first to third detection sensors.

For example, the controller 1200 may detect whether a human body is present in each of the occupied spaces based on at least one of the first sensor and the second sensor, and stop the operation of the corresponding occupant sterilization device. That is, based on the detection sensor installed in the dispenser or integrally installed in the room sterilization device 1900, whether or not a human body exists for each room is sensed, and the operation of the room sterilization device 1900 corresponding to the room in which the human body is detected can be stopped to minimize the effect on the human body.

Meanwhile, the controller 1200 may be configured to stop the operation of the surface sterilization unit provided in the main sterilization device by detecting the presence of a human body in the open space based on the third detection sensor. That is, based on the detection sensor provided in the main sterilization device 1800, it is possible to determine whether or not a human body exists in the space where the main sterilization device 1800 is disposed, and based on the sensing result, at least the main sterilization device ( 1800) may stop the operation of the surface sterilization unit (for example, an ultraviolet lamp). For example, the air sterilization unit of the main sterilization device 1800 may continue to operate even when a human body is detected.

surface sterilization unit

According to one embodiment of the present invention, the surface sterilization unit 1010 may be provided, for example, in at least one of the mobile sterilization device 1700, the main sterilization device 1800, and the occupied sterilization device 1900. It is not limited and may be included in the system in various forms and configured to sterilize the surface.

Specifically, the surface sterilization unit 1010 may be configured to sterilize a surface existing in an occupied space or an open space based on ultraviolet rays. For example, sterilization can be performed by radiating ultraviolet rays to a surface of a toilet (eg, a partition, a floor, a toilet bowl, a washbasin, etc.) of a toilet based on an ultraviolet radiation device such as an ultraviolet LED.

Visible light has red and purple as boundaries, and light in a region having a frequency higher than violet and lower than X-rays is called ultraviolet. Even the solar energy reaching the ground contains less than 5% of ultraviolet rays of 293~400[nm]. When playing in the water or going outdoors, it can be perceived as unfavorable light to the general public, such as applying sunscreen to the skin. In particular, in areas such as Australia, exposure to ultraviolet rays has increased due to the depletion of the ozone layer in the polar regions, and it is considered a necessity for outdoor activities, and its association with skin cancer is also known. On the other hand, in areas such as Gumi, it is also used as a light source for skin tanning, and its application as a sterilizer and ozone generator in the engineering field is growing.

In addition, ultraviolet rays are invisible wavelengths within the Solar Spectrum range and contain energy. Ultraviolet light is in a state almost similar to the wavelength of visible light, but the wavelength is shorter. Ultraviolet rays are measured as 1/1,000,000 mm, and the unit is expressed as angstrom (A) or nano meter (NM) and is divided into three areas: UV-A, UV-B, and UV-C.

The sterilization effect of ultraviolet rays is related to the wavelength of ultraviolet rays, and the wavelength is maximized around 250 ~ 260nm. Ultraviolet light absorbs ultraviolet energy of proteins and nucleic acids, which are the main components of all microorganisms, and disables or destroys the activity of DNA (deoxyr ibonucleic acid) of microorganisms. Thus, it prevents the growth and reproduction of microorganisms. That is, bacteria, fungi, viruses, etc. can be destroyed to generate a sterilization effect.

In general, organisms receive ultraviolet radiation, and molecules or cells in the part irradiated by the energy of the photon of the radiation cause chemical changes, even if abnormalities such as partial damage or injury occur, the cells in the part that are damaged or injured in it is restored by metabolism. Therefore, if the entire organism is large, the proportion of damaged or damaged parts is usually smaller than the total organism, so unless it is continuously irradiated with ultraviolet radiation thereafter, no situation directly related to the survival of the organism occurs.

However, when the size of an object is small, such as a microorganism such as a bacterium or fungus, the ratio of the damaged or injured part to the entire object increases, leading to the death of the microorganism. Using this, it becomes possible to kill harmful microorganisms by irradiating them with large ultraviolet rays of photon energy. This is the sterilizing action of ultraviolet radiation. The wavelength band of ultraviolet radiation in which the sterilization effect increases is 220 ~ 310 [nm]. Sunlight also contains ultraviolet radiation around 300 [nm], so if you dry your bedding on a very sunny day, you can sterilize various germs adhering to your bedding. In this case, humidity affects UV sterilization, and it can be seen that the effect increases as the humidity decreases. It is known for its sterilization efficiency of 100 [%] at a relative humidity of 60 [℃], sterilization efficiency of 67 [%] at a relative humidity of 70 [℃], and sterilization efficiency of 60 [%] at a relative humidity of 80 [℃]. The temperature also has an effect, and 20~25[℃] is optimal, and at 0[℃], the effect is about 60[%] higher than that at 20[℃].

When looking at transmittance, many materials do not transmit ultraviolet light, but some materials transmit only a limited range of wavelengths. The degree of penetration depends on the thickness and nature of the material. Generally, transparent water (about 10 to 80 [cm] as drinking water: 90 [%] absorption of sterilization lines) and air have good permeability. For reference, the transmission limit wavelength range of materials: water: 185 [nm], ordinary glass: 300 [nm], cellophane: 260 [nm], air: 190 [nm], cornea: 295.4 [nm], lens: 310 is [nm].

Examining the effect of ultraviolet radiation on the human body by wavelength range, ultraviolet radiation has many applications in the industrial field, but basically has a large energy, so it is necessary to avoid irradiation beyond a certain limit for the human body regardless of the irradiated part. Regarding the safety standard of the allowable amount of light irradiation, international standardization (IEC-CIE standardization) has been carried out in IEC and CIE since 1997, and in 2002, the basic general rules were recognized by the vote of CIE member countries, and the CIE standard was enacted and published as Also, some countries have established their own national standards. Among the national standards of each country, the ANSI standard of the United States is representative, and the aforementioned CIE international standard is the basis. Regarding the basic way of thinking of the safety standards of light sources (ultraviolet radiation) according to this CIE standard, biological or pathological studies have been conducted so far among biological injuries of the human body, and the effect of each wavelength has been studied.

air sterilization unit

According to one embodiment of the present invention, the air sterilization unit 1020 may be provided in at least one of, for example, a mobile sterilization device 1700, a main sterilization device 1800, or an occupied sterilization device 1900. It is not limited and may be included in the system in various forms and configured to sterilize the surface.

Specifically, the air sterilization unit 1020 may sterilize and deodorize the air around the photocatalyst by irradiating ultraviolet rays to the photocatalyst that responds to ultraviolet rays. The photocatalyst may be, for example, titanium dioxide, and a lamp for irradiating ultraviolet rays to the titanium dioxide may be provided. The photocatalyst reacts with ultraviolet rays and reacts with oxygen or hydrogen in the air introduced into the air sterilization unit to generate hydroxide (OH Radical), thereby performing air sterilization.

A catalyst refers to a role that changes or improves the reaction rate of an external substance without changing itself in a certain chemical reaction. For example, the photocatalyst uses titanium dioxide, which has increased photoreactivity by irradiation with ultraviolet rays of 280 nm or less, has excellent durability and abrasion resistance, and titanium dioxide itself is a non-toxic material and is an eco-friendly material that does not cause secondary pollution.

Looking at the photocatalytic reaction principle, electrons generated by irradiation of ultraviolet rays on the photocatalyst surface react with O ₂ , H ₂ O or H ₂ in the air, and generate superoxide anions and hydroxyl radical-based active oxygen on the surface of titanium dioxide. can In particular, hydroxyl radicals have high oxidation and reduction potentials, so they oxidize and precipitate volatile organic compounds (VOCS), which are the source of fine dust, to suppress the generation of fine dust, and to react with recalcitrant pollutants such as acetaldehyde to remove odors. can do. It can also oxidize harmful bacteria, including pathogenic bacteria and viruses. Therefore, it is possible to perform a sterilization action on the air in the space to be sterilized.

dispenser

As shown in FIG. 11, toilet paper dispensers 30-1, 20-3, and 20-1 are installed in toilets to which a system or device according to an embodiment of the present invention can be applied. 30-2, 30-3) may be provided.

As described above, the detection sensor 1101 may be referred to as, for example, the first detection sensor 1101 and may be configured to sense the presence or absence of a human body in the occupied space.

According to one aspect, the toilet paper dispenser 30 may include an emergency rescue button 31 for illegal voyeurism or an emergency situation. The control unit 1200 generates an alarm sound through a speaker provided in the bathroom in response to the operation of the emergency rescue button 31 and transmits a rescue message to the manager device 2000 linked to the comprehensive bathroom sterilization management system. can be configured.

Meanwhile, the remaining amount detection sensor 33 may be configured to sense the remaining amount of toilet paper provided in the toilet paper dispenser, and may detect the remaining amount of toilet paper through an arbitrary sensor such as, for example, a weight sensor or a laser sensor. When it is determined that the remaining amount is less than or equal to the critical amount, the control unit 1200 or the manager device 2000 may transmit insufficient remaining amount information so that toilet paper can be replaced.

The display unit 35 can display various types of information. For example, the display unit may be configured to display advertisements, and may display policy publicity or guide information from public institutions. Furthermore, the state information of the toilet may also be displayed through the display unit.

More specifically, but not limitedly, when the user finds an illegal photographer, pressing the emergency button sends an alarm sound from a speaker built into the dispenser, and the situation can be transmitted to the entrance monitor and the manager's smartphone. In the case of a dispenser using an advertisement screen, power is always required and electrical work may be required. Here, advertisements may include both public service advertisements and commercial advertisements. Meanwhile, a dispenser combined with only an alarm device without an advertising screen may be used as a battery. For example, it may be configured to confirm charging timing with a battery indicator light. On the other hand, by using a rechargeable battery, it is possible to transmit an emergency situation to the entrance monitor and manager at the same time as sending an alarm sound in case of an emergency, and the alarm sound emitted from the dispenser has the effect of stopping crime by stimulating the anxiety of illegal filmers. Signals can be sent to monitors and administrators to protect users' privacy from criminals.

display part

According to an embodiment of the present invention, a display unit 1400 may be further provided to display various types of additional information.

FIG. 15 is an exemplary view of the display unit of FIG. 10 . As shown in FIG. 15 , the display unit 1400 may be configured to display toilet status information. The controller 1200 may generate, for example, information on the state of the toilet based on information acquired through each component of the system and display it through the display unit.

As exemplarily shown in FIG. 15 , the state information of the toilet displayed through the display unit may include at least one of occupancy state information, temperature information, humidity information, and hygiene state evaluation information.

For example, whether or not each occupied space is in use can be determined based on a sensor provided for each occupied space, and occupancy for each of the at least one occupied space, such as an empty seat or occupancy, or an emergency situation, is displayed on the display unit 1400. Status information may be displayed. The occupied space in use and the number of empty seats may be displayed as numbers.

On the other hand, as additional information, information from various sensors such as a temperature sensor or a humidity sensor provided in the main sterilization device 1800, the room sterilization device 1900, or the mobile sterilization device 1700 or included as a separate configuration is It can be displayed on the display unit 1400 . For example, bathroom temperature information or bathroom humidity information may be displayed.

On the other hand, according to one aspect, information on the current sanitary condition of the toilet by the system or device according to an embodiment of the present invention may be displayed. For example, in FIG. 15, hygiene conditions such as 98% hygiene are expressed as numerical values.

The evaluation of the sanitary state may be determined by a logic based on various factors, such as, for example, a ratio of operation time to a standard time of a sterilizer or sterilizer, a distance from a surface to be sterilized, and an intensity of ultraviolet irradiation.

According to one aspect, the control unit 1200 may be configured to determine sanitary state evaluation information based on the space sterilization index and the surface sterilization index for the bathroom. For example, a space sterilization index representing the degree of sterilization of air in the bathroom may be calculated according to settings, and a surface sterilization index representing the degree of sterilization of the surface of the bathroom may be calculated. For example, it may be configured to determine comprehensive sanitary condition evaluation information by assigning a weight to any one of a space sterilization index and a surface sterilization index.

For example, the space sterilization index may be determined in inverse proportion to the volume of the space corresponding to the air sterilization unit and proportional to the operating time ratio of the air sterilization unit to the reference time period. According to one aspect, it may be determined by reflecting the measurement volume and measurement time ratio and the result of the space sanitary state experiment measured with respect to the reference volume and reference time ratio. For example, the relationship between the volume of one air sterilization unit and the state of space hygiene can be quantified through experiments. In addition, the relationship between the hygienic state according to the ratio of the operating time of the air sterilizing unit among the standard time intervals, such as 24 hours, may be determined through experiments. It may be configured to digitize or logicalize such a relationship to determine a space sterilization index corresponding to the operating time ratio for the current reference time period and the volume of one air sterilization unit. According to one aspect, an artificial neural network for calculating a space sterilization index may be provided. For example, by training an artificial neural network based on a plurality of learning data labeled as a sanitary condition evaluation value determined based on a result of measuring the volume of one air sterilization unit and the operating time ratio for a reference time period, A space sterilization evaluation model that outputs a space sterilization index may be implemented by inputting the volume of one air sterilization unit and the operating time ratio for the reference time period.

Meanwhile, the surface sterilization index may be determined in inverse proportion to an evaluation value of a distance from the surface sterilization unit to the surface to be sterilized and proportional to an operating time ratio of the surface sterilization unit to a reference time interval. For example, the reference distance evaluation value may be an average value of distances of the mobile sterilization device 1700 from points on a moving path along which the mobile sterilization device moves to the surface to be sterilized.

According to one aspect, it may be determined by reflecting the measured distance evaluation value and the measurement time ratio and the surface sanitary condition test result measured with respect to the reference distance evaluation value and the reference time ratio. For example, the relationship between the reference distance evaluation value and the surface sanitary condition can be quantified by experimentation. In addition, the relationship between the surface sanitary state according to the ratio of the operating time of the surface sterilizing unit among the standard time intervals, such as 24 hours, can be determined by experimentation. It may be configured to quantify or logicalize such a relationship to determine a surface disinfection index corresponding to an operating time ratio for a current reference time period and a reference distance evaluation value. According to one aspect, an artificial neural network for calculating a surface disinfection index may be provided. For example, current measured distance evaluation by training an artificial neural network based on a plurality of learning data labeled with a sanitary state evaluation value determined based on a measurement result of a measured distance evaluation value and an operating time ratio for a reference time interval. It is also possible to implement a surface sterilization evaluation model that outputs a surface sterilization index by inputting the operating time ratio for the value and the reference time interval.

Regarding the evaluation of hygiene status, the following criteria may be reflected. For example, in relation to the space sterilization index, the sterilization efficiency increases in proportion to the sterilization time per rube (1 cubic meter), the sterilization efficiency increases in proportion to the time (irradiation time) of the air sucked into the sterilizer, the rube ( The sterilization efficiency decreases in inverse proportion to the sterilization space per 1 cubic meter, or the sterilization efficiency increases and decreases in inverse proportion to the sterilization time and space per rube (1 cubic meter), and at least one of these criteria is reflected and implemented as logic. After sterilization, the sterilization effect can be reflected in the hygiene index by calculating test data for each installation location. In addition, regarding the surface sterilization index, sterilization efficiency increases in proportion to UV-C wavelength type and irradiation time, sterilization efficiency decreases in inverse proportion to UV-C wavelength type and distance, and sterilization efficiency decreases in inverse proportion to UV-C wavelength type and sterilization time and distance It is possible to reflect at least one of criteria such as increase or decrease in sterilization efficiency and implement it as a logic, and after sterilization, test data for each installation location of the sterilization effect can be calculated and reflected in the sanitary index.

Meanwhile, as shown in FIG. 15 , information displayed on the display unit 1400 may be configured to be transmitted and displayed to the manager device 2000 of the system according to an embodiment of the present invention. According to one aspect, the information displayed on the display unit 1400 may include toilet management record book information. In general, it is coated on a cosmetic wall surface, and a management record ledger can be prepared at a predetermined time period through a marker so that users can check it. According to one aspect of the present invention, information displayed on the display unit 1400 may include management record book information for the toilet. For example, the manager device 2000 may be equipped with a management record ledger input function and the manager may be configured to input ledger information into the management record ledger in the manager device 2000 . According to one aspect, the controller 1200 determines whether the manager device 2000 is located inside the toilet based on any one of various means such as GPS information of the manager device 2000 or beacon information that can only be received at a short distance. , and in response to determining that the manager device 2000 is present in the bathroom, the management record ledger information can be input.

Toilet comprehensive control system

According to one embodiment of the present invention, it is possible to perform management of a plurality of toilets by one integrated control system. For example, a comprehensive bathroom control system according to an embodiment of the present invention may include a first comprehensive bathroom sterilization management system, a second comprehensive bathroom sterilization management system, and a control server.

Here, the first comprehensive bathroom sterilization management system and the second comprehensive bathroom sterilization management system may include at least some components of the comprehensive bathroom sterilization management system according to an embodiment of the present invention described above.

The control server is configured to receive a message about toilet state information from a plurality of toilet comprehensive sterilization management systems including a first toilet comprehensive sterilization management system and a second toilet comprehensive sterilization management system. The toilet state information may include various types of information such as sterilization information, remaining amount of toilet paper information, safety information, or occupancy information as discussed above.

In addition, the control server may store the received toilet state information in a database to secure state information on a plurality of toilets, manage the history, and utilize it as reference information for toilet management.

Meanwhile, the control server may be configured to transmit a control message to a plurality of toilet comprehensive sterilization management systems. At least some of various components including the bathroom sterilization device may be easily controlled by the control server.

For example, the multiple toilet comprehensive management system may correspond to multiple toilets included in one building or may correspond to multiple toilets located in different buildings and/or areas. Therefore, according to one aspect of the present invention, it is possible to centralize and unify management of numerous toilets in one control center.
