[0009] The cleaning and disinfecting system according to the present embodiment will be described with reference to the drawings. The same or corresponding components are designated by the same reference numerals, and the repeated description may be omitted.

[0010] Embodiment 1 1 is a circuit block diagram of a cleaning and disinfecting system 1 according to Embodiment 1. The cleaning and disinfecting system 1 includes a management device 10, a terminal device 20, a sterilization device 30, an image sensor 40, and a cleaning robot 50.

[0011] The management device 10 monitors and sets the overall status of the cleaning and disinfecting system 1. A plurality of lighting fixtures 21 are connected to the terminal device 20. The plurality of lighting fixtures 21 are arranged on the ceiling of an indoor space 100 (see, for example, FIG. 4) of a building or the like. The terminal device 20 controls the operation of the lighting fixtures 21.

[0012] The sterilization device 30 is, for example, a sterilization lamp. A sterilization lamp is also called a germicidal lamp. The sterilization device 30 is an example of a "sterilization device" that sterilizes the indoor space 100. The sterilization device according to the present disclosure may be any device that sterilizes, removes bacteria, and inactivates viruses in the indoor space 100, and may be, for example, a ventilation fan or an air purifier instead of the sterilization device 30.

[0013] The image sensor 40 is a sensor that detects people in the indoor space 100. More specifically, the image sensor 40 detects, for example, the presence or absence of people, the number of people, and the positions of the people in the indoor space 100. The image sensor 40 is disposed, for example, on the ceiling of the indoor space 100.

[0014] The cleaning and disinfecting system 1 may include one or more terminal devices 20, sterilizers 30, and image sensors 40. In this embodiment, as shown in FIG. 4 and other figures described later, groups of terminal devices 20, sterilizers 30, and image sensors 40 are arranged in an array at intervals in the indoor space 100. More specifically, a plurality of areas are formed inside the indoor space 100, with each group of terminal devices 20, sterilizers 30, and image sensors 40 at the center. In other words, the groups of terminal devices 20, sterilizers 30, and image sensors 40 are arranged in a plurality of areas while being linked to each other.

[0015] The cleaning robot 50 cleans the indoor space 100. Specifically, the cleaning robot 50 is configured to be capable of autonomous travel, and cleans, for example, at least one of the floor surface and the wall surface of the indoor space 100. The cleaning robot 50 is, for example, a suction type robot equipped with a brush, or a suction type robot without a brush. The cleaning robot 50 may also be equipped with, for example, at least one of a disinfectant sprayer and an ultraviolet irradiator.

[0016] The management device 10 is connected to the terminal device 20, the sterilizer 30, and the image sensor 40 via a communication line 2 connected by a jumper wiring. The management device 10 communicates with each of the terminal device 20, the sterilizer 30, and the image sensor 40 via the communication line 2. More specifically, the management device 10 transmits and receives transmission signals between the terminal device 20, the sterilizer 30, and the image sensor 40 connected via the communication line 2. The transmission signals include, for example, address data and control data.

[0017] Unique addresses are assigned to the terminal device 20, the sterilization device 30, and the image sensor 40, and these devices are identified by the addresses assigned to each of them. The management device 10 communicates with the terminal device 20 and causes the terminal device 20 to control the lighting state of the lighting fixtures. The management device 10 also controls the operation of the sterilization device 30.

[0018] The management device 10 and the cleaning robot 50 are connected via a wireless LAN (Local Area Network) 3 that transmits and receives data using wireless communication. The wireless LAN is, for example, Wi-Fi (registered trademark). A unique IP (Internet Protocol) address is assigned to the cleaning robot 50. The cleaning robot 50 is identified by the assigned IP address. A control signal from the management device 10 is transmitted to the cleaning robot 50 via the wireless LAN 3. As a result, the operation of the cleaning robot 50 is controlled by the management device 10.

[0019] Fig. 2 is a functional block diagram of management device 10 according to embodiment 1. Fig. 3 is a diagram showing a part of the hardware configuration of management device 10 according to embodiment 1. As shown in Fig. 2, management device 10 includes a communication unit 11, a control unit 12, a storage unit 13, and a cleaning route calculation unit 14. Storage unit 13 corresponds to the memory in Fig. 3.

[0020] The storage unit 13 is a non-volatile memory such as a flash memory. The storage unit 13 stores software for the management device 10, various information based on the results of human detection by the image sensor 40, the cleaning route, and the operating status of the cleaning robot 50. The various information here includes information on the presence or absence of people, information on the number of people, and information on the density of people. The communication unit 11 transmits and receives control data to and from the terminal device 20, the sterilization device 30, and the image sensor 40 via the communication line 2. The communication unit 11 also transmits and receives control signals to and from the cleaning robot 50 via the wireless LAN 3.

[0021] Based on the result of human detection by the image sensor 40, the control unit 12 causes the terminal device 20 to control the lighting state of the lighting fixtures 21, controls the operation of the sterilizer 30, and controls the operation of the cleaning robot 50. The cleaning route calculation unit 14 calculates an optimal cleaning route for the cleaning robot 50 based on the congestion information from the control unit 12.

[0022] The functions of each of the communication unit 11, control unit 12, and cleaning route calculation unit 14 are realized by a control device such as a processor shown in Fig. 3. The control device may be dedicated hardware. The control device may also be a CPU (Central Processing Unit) that executes a program stored in a memory. A CPU is also called a central processing unit, processing device, arithmetic unit, microprocessor, microcomputer, processor, or DSP.

[0023] When the control device is a dedicated hardware, the control device may be, for example, a single circuit, a composite circuit, a programmed processor, or a parallel programmed processor. The control device may also be an ASIC (Application Specific Integrated Circuit) or an FPGA (Field-Programmable Gate Array). The control device may also be a combination of these. The functions of each of the communication unit 11, the control unit 12, and the cleaning route calculation unit 14 may each be realized by a control circuit. The functions of each unit may also be realized collectively by the control device.

[0024] When the control device is a CPU, the functions of the communication unit 11, the control unit 12, and the cleaning route calculation unit 14 are realized by software, firmware, or a combination of software and firmware. The software and firmware are written as programs and stored in memory. The control device realizes the functions of the communication unit 11, the control unit 12, and the cleaning route calculation unit 14 by reading and executing the programs stored in the memory. In other words, it can be said that the programs stored in the memory cause the computer to execute the procedures or methods of the communication unit 11, the control unit 12, the memory unit 13, and the cleaning route calculation unit 14.

[0025] Here, the memory may be a non-volatile or volatile semiconductor memory such as RAM, ROM, flash memory, EPROM, EEPROM, etc., a magnetic disk, a flexible disk, an optical disk, a compact disk, a mini disk, or a DVD, etc. RAM is an abbreviation for Random Access Memory. ROM is an abbreviation for Read Only Memory. EPROM is an abbreviation for Erasable Programmable Read Only Memory. EEPROM is an abbreviation for Electrically Erasable Programmable Read-Only Memory.

[0026] It should be noted that the functions of the communication unit 11, the control unit 12, and the cleaning route calculation unit 14 may be partially realized by dedicated hardware and partially realized by software or firmware. For example, the functions of the communication unit 11 and the cleaning route calculation unit 14 may be realized by a control device as dedicated hardware, and the function of the control unit 12 may be realized by the control device reading and executing a program stored in a memory.

[0027] In this manner, the control device can realize each of the above-described functions by hardware, software, firmware, or a combination of these.

[0028] The control signal is, for example, a signal that controls the cleaning robot 50. However, the control signal is not limited to this, and may be a signal that controls the lighting device 21 of the terminal device 20. The control signal may also be a signal that controls the sterilization device 30. In this way, the control signal includes all signals transmitted and received among the cleaning robot 50, the terminal device 20, the sterilization device 30, and the image sensor 40.

[0029] Next, specific control of the terminal device 20, the sterilizer 30, and the cleaning robot 50 by the control unit 12 of the management device 10 will be described with reference to Figs. 4, 5, and 6.

[0030] When the image sensor 40 receives a signal requesting at least one of human presence information and number of people information based on the human detection result from the management device 10, the image sensor 40 transmits at least one of the corresponding presence information and number of people information to the management device 10. In addition, when the detected number of people changes, the image sensor 40 transmits updated number of people information to the management device 10.

[0031] First, the control unit 12 controls the terminal device 20 for each of a plurality of areas based on the presence / absence information of a person. Specifically, when the control unit 12 receives the presence / absence information indicating the presence of a person in the indoor space 100 from the image sensor 40, the control unit 12 transmits a control signal for the lighting device 21 connected to the terminal device 20 to the terminal device 20 associated with the image sensor 40 that transmitted the presence / absence information. More specifically, the control unit 12 controls the lighting state of the lighting device 21 of the terminal device 20. For example, the control unit 12 controls the terminal device 20 to turn on the lighting device 21.

[0032] Next, in order to control the sterilization device 30 and the cleaning robot 50, the control unit 12 judges the density of people based on the detection result of people by the image sensor 40. The density may be judged for the entire indoor space 100, but in the following example, it is judged for each of the above-mentioned multiple areas.

[0033] In this embodiment, the density is determined using the following conditions 1, 2, and 3. In condition 3, the specific time is, for example, one minute, and "staying in the same place" includes moving at a slow speed less than a threshold. Note that the staying time and moving speed in condition 3 are measured by the management device 10 by accumulating information transmitted from the image sensor 40. Condition 1: 1m 2 The number of winners must be 1 or more Condition 2: The person is moving and the distance between people in front, behind, on either side is less than 1m. Condition 3: Multiple people staying in the same place for a specific period of time

[0034] The control unit 12 determines that the density is higher than the density threshold when at least one of the above conditions 1, 2, and 3 is satisfied. In the following description, the density being higher than the density threshold is also simply referred to as "high density."

[0035] The control unit 12 determines whether to control the sterilization device 30 based on the density. Specifically, when the time during which the density exceeds the density threshold in a "specific area" included in the multiple areas of the indoor space 100 exceeds a first time threshold, the control unit 12 activates the sterilization device 30 arranged in the specific area. In the following description, "the time during which the density exceeds the density threshold exceeds the first time threshold" is also simply referred to as "the density is momentarily exceeded." The first time threshold is a value that is predetermined to determine whether the density is momentarily exceeded. Note that the sterilization device 30 associated with the image sensor 40 used to determine that the density is momentarily exceeded is identified as the sterilization device 30 arranged in the specific area.

[0036] FIG. 4 is a diagram showing an example of the operation of the sterilization device 30 according to the first embodiment. In the example shown in FIG. 4, 15 areas are formed in the indoor space 100, with the groups of the terminal device 20, the sterilization device 30, and the image sensor 40 at the center. In the example shown in FIG. 4, two areas in which the groups A and B are arranged correspond to the above-mentioned specific areas, and the density is momentarily exceeded in the specific areas. For this reason, the control unit 12 transmits a control signal to the sterilization device 30 in these two specific areas to start the operation of the sterilization device 30. Note that even if the density becomes higher than the density threshold, if the time does not reach the first time threshold, the sterilization device 30 is not operated.

[0037] The management device 10 determines a cleaning route for the cleaning robot 50 based on the congestion. Specifically, in this embodiment, the control unit 12 transfers the congestion information to the cleaning route calculation unit 14 and instructs the cleaning route calculation unit 14 to optimize the cleaning route for the cleaning robot 50. The optimized cleaning route is transmitted to the cleaning robot 50 via, for example, the wireless LAN 3.

[0038] In this embodiment, the optimization of the cleaning route based on the density is performed as follows, for example. That is, first, the control unit 12 judges whether the density is exceeded instantaneously or for a certain period of time for each of the multiple areas. Here, "whether the density is exceeded for a certain period of time" is judged based on whether the time during which the density exceeds the density threshold exceeds a second time threshold. The second time threshold is a value that is predetermined to be longer than the first time threshold.

[0039] If the route includes an area where the density exceeded the limit momentarily but does not include an area where the density exceeded the limit for a certain period of time, the cleaning route calculation unit 14 uses the regular cleaning route as shown in FIG. 5 as is. That is, in this case, the cleaning route is not changed. On the other hand, if the route includes an area where the density exceeded the limit for a certain period of time, the control unit 12 instructs the cleaning route calculation unit 14 to reconstruct the cleaning route. Accordingly, the cleaning route calculation unit 14 creates an emergency cleaning route as will be described with reference to FIG. 6.

[0040] Fig. 5 is a diagram showing an example of a regular cleaning route of the cleaning robot 50 according to the first embodiment. The example shown in Fig. 5 corresponds to the example shown in Fig. 4 described above, and the sterilization device 30 is operating in groups A and B. The regular cleaning route is a basic cleaning route of the cleaning robot 50. In the example of the regular cleaning route shown in Fig. 5, the cleaning robot 50 starts from an area located at one end of the indoor space 100, ends at an area located at the opposite end to the one end, and moves so as to pass through all areas.

[0041] The regular cleaning route is transmitted from the management device 10 to the cleaning robot 50 via the wireless LAN 3. The cleaning robot 50 starts cleaning each area from the start point to the end point according to the regular cleaning route. More specifically, the cleaning robot 50 starts cleaning when an area is found to be momentarily overcrowded. Alternatively, the cleaning robot 50 may operate at a scheduled date and time, for example. The regular cleaning route may also be changed depending on the date and time.

[0042] 5, the cleaning robot 50 passes through groups A and B where the sterilization device 30 has been activated during cleaning. In this manner, the cleaning robot 50 cleans the specific area where the sterilization device 30 has been activated based on the crowding degree, in accordance with an instruction from the management device 10.

[0043] The operation of the sterilization device 30 in response to a momentary excess of the crowding degree may be performed for, for example, a preset time. Instead of such an example, the cleaning robot 50 may clean the specific area in which the sterilization device 30 is operating, and then transmit a control signal indicating that cleaning of the specific area has been completed to the management device 10. Then, the management device 10 may stop the operation of the sterilization device 30 accordingly. Alternatively, the management device 10 may stop the operation of the sterilization device 30 a certain time after receiving the control signal from the cleaning robot 50.

[0044] After reaching the end point, the cleaning robot 50 may send a control signal to the management device 10 indicating completion of cleaning and stop cleaning. Alternatively, after reaching the end point, the cleaning robot 50 may return to the section from the start point to the end point and continue cleaning in reverse, or may send a control signal to the management device 10 requesting the next cleaning route.

[0045] Next, FIG. 6 is a diagram showing an example of an emergency cleaning route of the cleaning robot 50 according to the first embodiment. The emergency cleaning route is selected when an area occurs in which the density exceeds a certain period of time. The cleaning route calculation unit 14 specifies the area in which the density exceeds a certain period of time as a "priority area" in which cleaning by the cleaning robot 50 is prioritized. In the example shown in FIG. 6, the area in which group C is located corresponds to the priority area. Note that in FIG. 6, the area in which group B is located corresponds to an area in which the density momentarily exceeds a certain period of time, similar to the example shown in FIG. 4.

[0046] Then, the cleaning route calculation unit 14 changes the cleaning route so that the identified priority route becomes the emergency cleaning route with priority. More specifically, in the example shown in FIG. 6, when the cleaning robot 50, which is performing cleaning according to the regular cleaning route, is at position P, the congestion exceeds a certain period of time in the area where group C is located. In such a case, the control unit 12 transfers the congestion information to the cleaning route calculation unit 14 and instructs the cleaning route calculation unit 14 to create an emergency cleaning route. As shown in FIG. 6, the cleaning route calculation unit 14 omits cleaning of the areas where groups D and E, which are not crowded with people, are located, and creates a cleaning route that goes to the area where group C is located in the shortest time as an emergency cleaning route.

[0047] The created emergency cleaning route is transmitted to the cleaning robot 50 via the wireless LAN 3. The cleaning robot 50 continues cleaning according to the received emergency cleaning route. Unlike the example shown in FIG. 6, even if an area occurs where the congestion level exceeds a certain period of time while the cleaning robot 50 is not cleaning according to the regular cleaning route, the cleaning route calculation unit 14 may similarly create an emergency cleaning route that prioritizes that area. Then, the cleaning robot 50 may immediately start cleaning according to the created emergency cleaning route.

[0048] Here, we will provide a supplementary explanation regarding the specification of the priority area. There may be a case where multiple areas satisfy any one of the above conditions 1 to 3. In this case, the area with the greater number of people related to any of the corresponding conditions 1 to 3 may be given priority. For example, with regard to condition 1, 2 If there are areas with two people and areas with three people, the area with three people is prioritized. If any one of conditions 1 to 3 is commonly satisfied in multiple areas and the number of people related to that condition is the same, the area with the greater number of conditions 1 to 3 that apply is prioritized. If there are multiple areas with the same number of conditions 1 to 3 that apply and the same number of people related to each condition, the areas may be prioritized in order of proximity to the current position of the cleaning robot 50. If there are multiple areas where the congestion level has exceeded a certain period of time, an emergency cleaning route may be generated so that the multiple areas are cleaned in order according to the priority order described above.

[0049] Furthermore, in the area where group C is located, the operation of the sterilization device 30 is started when the congestion level momentarily exceeds the limit. However, if the operation of the sterilization device 30 started in this manner has already ended when the congestion level subsequently exceeds the limit for a certain period of time, the control unit 12 may control the sterilization device 30 to restart the operation of the sterilization device 30 in response to the occurrence of the congestion level exceeding the limit for a certain period of time.

[0050] The operation of the sterilization device 30, which is started in response to the occurrence of the congestion exceeding a certain period of time, may be performed for, for example, a preset period of time. Alternatively, the cleaning robot 50 may clean the priority area in which the sterilization device 30 is operating, and then transmit a control signal indicating that cleaning of the priority area has been completed to the management device 10. Then, the management device 10 may stop the operation of the sterilization device 30 accordingly. Alternatively, the management device 10 may stop the operation of the sterilization device 30 a certain period of time after receiving the control signal from the cleaning robot 50.

[0051] In the cleaning and disinfecting system 1 described above, the management device 10 not only controls the lighting state of the lighting fixtures 21 based on the detection result of a person by the image sensor 40, but also controls the operations of the sterilizer 30 and the cleaning robot 50 based on the detection result. In this way, a cleaning and disinfecting system 1 suitable for preventing the spread of infection in the indoor space 100 can be obtained.

[0052] Furthermore, the management device 10 determines the density of people based on the detection result of people by the image sensor 40, and determines a cleaning route for the cleaning robot 50 based on the density. More specifically, the management device 10 determines the density for each of a plurality of areas. Then, when the time during which the density exceeds the density threshold in a specific area included in the plurality of areas exceeds a first time threshold, the management device 10 activates the sterilization device 30 arranged in the specific area, and further causes the cleaning robot 50 to clean the specific area. This makes it possible to effectively suppress the spread of infection.

[0053] Furthermore, the management device 10 identifies an area where the time during which the density exceeds the density threshold exceeds a second time threshold, which is longer than the first time threshold, as a priority area to be cleaned by the cleaning robot 50. Then, the management device 10 changes the cleaning route so that the identified priority area becomes an emergency cleaning route that prioritizes the priority area. This allows areas that truly need cleaning to be cleaned quickly, making it possible to more effectively suppress the spread of infection.

[0054] The cleaning and disinfecting system 1 according to the above-mentioned first embodiment may have the following configuration.

[0055] The management device 10 may accumulate the route that the cleaning robot 50 actually traveled during cleaning in the memory unit 13. Then, in order to optimize the cleaning route of the cleaning robot 50, the management device 10 may grasp the density and frequency of use of each area for each time period, day of the week, and season from the accumulated routes, and may learn the optimal cleaning route according to the time period, day of the week, and season.

[0056] The management device 10 may also transfer information about areas where the density is not momentarily excessive to the cleaning route calculation unit 14 and instruct the cleaning route calculation unit 14 to exclude the areas from the cleaning route of the cleaning robot 50. In this way, the operation of the cleaning robot 50 may be made more efficient.

[0057] Furthermore, the management device 10 may set a first time threshold and a second time threshold for each area to determine whether the congestion level is exceeded momentarily or for a certain period of time, respectively.

[0058] Furthermore, the number of cleaning robots 50 is not limited to one. That is, the cleaning and disinfecting system 1 may include separate cleaning robots for regular cleaning routes and robots for emergency cleaning routes, and these cleaning robots may be operated simultaneously.

[0059] The cleaning robot 50 may also be equipped with a camera. The camera may be used together with the image sensor 40 to determine the degree of crowding.

[0060] In addition, if the congestion level on the cleaning route continues to be high, the cleaning robot 50 may make an announcement, for example, using a speaker, to encourage people to eliminate the congestion. In addition, the cleaning robot 50 may stop moving along the route until the congestion level is improved, and may intensify cleaning by extending the cleaning time in the highly crowded areas.

[0061] Furthermore, when an area on the cleaning route where people move and stay is small is identified in advance, the management device 10 may exclude the area in advance from the route of the cleaning robot 50. Then, the management device 10 may disinfect such an area using a disinfection device such as the sterilization device 30.

[0062] The management device 10 may also accumulate and analyze information transmitted from the image sensor 40 to estimate areas where crowding is likely to be high. The management device 10 may then set a cleaning route to focus on cleaning the estimated areas.

[0063] In addition, the cleaning and disinfection system 1 may perform at least one of the operation of a disinfection device such as the sterilization device 30 and cleaning by the cleaning robot 50 in conjunction with at least one of a heat exchange type ventilation device such as Lossnay (registered trademark) and an air conditioning facility.

[0064] The technical features described in the present embodiment and the modified examples may be used in appropriate combinations. [Explanation of symbols]
