DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] (The knowledge and other information that formed the basis of this disclosure)

[0011] At the time the inventors came up with the present disclosure, there was technology available for a store display system that classified and displayed the customer behavior in each area within a store in a display format according to the number of people in each area, and appropriately presented the customer behavior in each area. On the other hand, there is a risk that the sales floor will become negatively pressurized due to various factors such as insufficient exhaust in the back yard adjacent to the sales floor in the store, the door to the sales floor being open, and improper operation of the air supply fan. When the sales floor becomes negatively pressurized, outside air and air from the back yard will flow into the sales floor of the store. In particular, when outside air flows into the sales floor, problems such as the inflow of dust, high air conditioning load, and high cooling load will occur. Even if the sales floor becomes negative pressure, the sales floor can be made positive pressure by the store staff taking measures such as increasing the amount of air supplied to the sales floor or closing the door. However, the inventors have discovered a problem that the store staff was not aware that air was flowing into the sales floor because there was no mechanism to notify the store staff that the sales floor was negative pressure. The inventors have come up with the subject of the present disclosure in order to solve the above problem with a simple configuration. Therefore, the present disclosure provides an information display system, an information display method, and a program that can detect, with a simple configuration, a condition in which there is a possibility of air flowing into a store's sales floor and notify the user that measures are necessary.

[0012] Hereinafter, the embodiments will be described in detail with reference to the drawings. However, more detailed explanation than necessary may be omitted. For example, detailed explanation of already well-known matters or duplicate explanation of substantially the same configuration may be omitted. This is to avoid the following explanation becoming more redundant than necessary and to facilitate understanding by those skilled in the art. It should be noted that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0013] (Embodiment) Hereinafter, the embodiment will be described with reference to FIGS. 1 to 9. FIG. [1. Configuration] 1 is an explanatory diagram of a store 100 in which an information display system according to this embodiment is used. The information display system according to this embodiment is configured to include an alert system 1, a first differential pressure sensor 46, a second differential pressure sensor 47, and a display device 50 (see FIG. 3). The alert system 1 and the display device 50 configure a display terminal used in the store of the present disclosure.

[0014] Store 100 is a store that sells food products, and is divided into sales floor 110 within store 100 and back yard 120 adjacent to sales floor 110. Sales floor 110 corresponds to a first space in this disclosure, and back yard 120 and the outside of store 100 adjacent to sales floor 110 correspond to a second space in this disclosure. Back yard 120 includes work spaces 160, 161 equipped with exhaust devices 121-124, a truck yard 130 for carrying in and out packages by delivery vehicles 150, 151, etc., and an office space 140 equipped with an alarm system 1. Work spaces 160, 161 are kitchens where food is cooked, work areas for distributing food, etc.

[0015] The exhaust devices 121-124 are connected to an exhaust port 125 via exhaust pipes and exhaust air from the work spaces 160, 161. The ventilation device 70 is provided on the ceiling or the like of the sales floor 110 and connected to an intake port 72, supplying outside air to the sales floor 110 and returning air from the sales floor 110 to the back yard 120. The entrance / exit 111 of the store 100 is equipped with sliding doors 111a, 111b that open and close in response to detection of the presence or absence of an approaching person or in response to a human operation. Similarly, the entrance / exit 112 of the store 100 is also equipped with sliding doors 112a, 112b.

[0016] Entrances 113, 114 between the sales floor 110 and the back yard 120 are equipped with swing-type doors 113a, 114a, respectively. An entrance 131 of the truck yard 130 is equipped with a shutter-type door 131a. An entrance 112 of the sales floor 110 is provided with a first differential pressure sensor 46 that detects the differential pressure (= pressure on the sales floor 110 side - pressure outside the store 100) between the pressure on the sales floor 110 side of the entrance 112 and the pressure outside the store 100 (outside air side). In addition, a first door opening / closing sensor 44 that detects the open / closed state of the door 112a is provided at the entrance 112.

[0017] At the entrance 113 between the sales floor 110 and the back yard 120, a second differential pressure sensor 47 is provided which detects the differential pressure between the pressure on the sales floor 110 side of the entrance 113 and the pressure on the back yard 120 side (= pressure on the sales floor 110 side - pressure on the back yard 120 side). At the entrance 131 of the truck yard 130, a third differential pressure sensor 48 is provided which detects the differential pressure between the pressure on the back yard 120 side and the pressure outside (outside air side) of the store 100 (= pressure on the back yard 120 side - pressure outside the store 100 (= pressure on the back yard 120 side - pressure outside the store 100). At the entrance 131 of the truck yard 130, a second door opening / closing sensor 45 is provided which detects the open / closed state of the door 131a.

[0018] FIG. 2 shows the ventilation state of the store 100 by the ventilation device 70 and the exhaust devices 121-124. The ventilation device 70 is composed of a first ventilation device 70a and a second ventilation device 70b. The first ventilation device 70a takes in outside air OA from an air intake 72 and supplies supply air SA to the sales floor 110. The second ventilation device 70b takes in return air RA from the sales floor 110 and supplies supply air SA to the backyard 120 (including the work spaces 160, 161). The exhaust devices 121-124 exhaust exhaust air EA from the work spaces 160, 161 to the outside from an exhaust port 125. FIG. 2 shows a door 165a provided at the entrance between the work spaces 160, 161 and the backyard 120.

[0019] Next, the configuration of the notification system 1 will be described with reference to FIG. 3. The notification system 1 is a computer system including a processor 10, a memory 20, a communication unit 30, and the like. The processor 10 is a controller that controls the operation of the notification system 1. The notification system 1 is connected to a temperature sensor 40, a humidity sensor 41, and a CO2 sensor 42 provided in the sales floor 110, a dust sensor 43 provided outside the store 100 for detecting the concentration of dust around the store 100, and the above-mentioned first door opening / closing sensor 44, second door opening / closing sensor 45, first differential pressure sensor 46, second differential pressure sensor 47, and third differential pressure sensor 48. Detection signals of these sensors are input to the notification system 1.

[0020] The notification system 1 is connected to a display device 50, and a screen displayed on the display device 50 is controlled by image data output from the notification system 1. The display device 50 is a terminal device having a display function, such as a personal computer or a tablet terminal, and an image displayed on the display device 50 is visually confirmed by a manager A1 of the store 100. Furthermore, the notification system 1 is connected to a ventilation device 70, and operation status information indicating the operation status of the ventilation device 70 is input to the notification system 1.

[0021] The operation schedule of the ventilation device 70 is set by a remote control 71, and the ventilation device 70 supplies air to the sales floor 110 so as to maintain positive pressure within the sales floor 110 based on the detection signals of the first differential pressure sensor 46, the second differential pressure sensor 47, and the third differential pressure sensor 48, the operating status of the exhaust devices 121-124, etc.

[0022] The notification system 1 communicates with a weather information server 210, a store management server 220, a mobile terminal 60 used by a manager A2 of the store 100, etc., via a communication network 200 using a communication unit 30. The mobile terminal 60 is a smartphone, mobile phone, tablet terminal, etc., and communicates with the notification system 1 by executing a store management app (application program).

[0023] By operating the ventilation device 70, the pressure in the sales floor 110 is basically maintained in a state (first space positive pressure state) higher than the pressure in the backyard 120 and outside the store 100. However, if any of the doors 111b, 112b, 113a, 114a is left open by mistake, or due to various factors such as an error in setting the operation schedule of the ventilation device 70, the pressure in the sales floor 110 may become lower than the pressure in the backyard 120 or outside the store 100 (first space negative pressure state). Therefore, the notification system 1 monitors whether the sales floor 110 is in the first space negative pressure state, and when the sales floor 110 becomes the first space negative pressure state, a notification is given by the display device 50, thereby preventing the sales floor 110 from being left in the first space negative pressure state.

[0024] The processor 10 reads and executes a program 21 for controlling the notification system 1 stored in the memory 20, thereby functioning as a differential pressure determination unit 11, a door opening / closing recognition unit 12, a ventilation device operation recognition unit 13, an airborne substance concentration recognition unit 14, and a display control unit 15. The program 21 may be read from a recording medium (optical disk, flash memory, etc.) by the notification system 1 and stored in the memory 20, or may be downloaded from an external system such as a store management server 220 by the notification system 1 and stored in the memory 20. The processor 10 corresponds to the processor of a display terminal used in the store of the present disclosure.

[0025] The differential pressure determination unit 11 recognizes the differential pressure between the atmospheric pressure in the selling floor 110 and the atmospheric pressure outside the store 100 based on the detection signal of the first differential pressure sensor 46, and recognizes the differential pressure between the atmospheric pressure in the selling floor 110 and the atmospheric pressure in the backyard 120 based on the detection signal of the second differential pressure sensor 47. In addition, the differential pressure determination unit 11 recognizes the differential pressure between the atmospheric pressure in the backyard 120 and the store 100 based on the detection signal of the third differential pressure sensor 48.

[0026] The door open / close recognizing unit 12 recognizes the open / closed state of the door 112a of the entrance / exit 112 of the store 100 based on the detection signal of the first door open / close sensor 44. The door open / close recognizing unit 12 also recognizes the open / closed state of the door 131a of the entrance / exit 131 of the truck yard 130 based on the detection signal of the second door open / close sensor 45. The ventilation device operation recognizing unit 13 recognizes the operation state of the ventilation device 70 based on the operation state information of the ventilation device 70.

[0027] The airborne substance concentration recognition unit 14 recognizes the concentration of dust around the store 100 based on a detection signal from a dust sensor 43 installed outside the store 100. Dust corresponds to the target airborne substance of the present disclosure. The target airborne object may be a substance other than dust, such as yellow sand or pollen. The airborne substance concentration recognition unit 14 may recognize the concentration of airborne substances around the store 100 by receiving and acquiring information on the concentration of airborne substances in the area where the store 100 is located, which is provided from the weather information server 210, via the communication unit 30. The CO2 concentration recognition unit 15 recognizes the concentration of CO2 in the sales floor 110 based on a detection signal from a CO2 sensor 42 installed in the sales floor 110.

[0028] The display control unit 16 notifies the manager A1 by displaying the screen of the display device 50 by transmitting image data to the display device 50. In addition, the display control unit 16 notifies the manager A2 by displaying the screen of the display unit of the mobile terminal 60 by transmitting image data to the mobile terminal 60 used by the manager A2 of the store 100.

[0029] [2. Notification Processing] The notification process regarding the positive and negative pressure conditions in the sales floor 110, which is executed by the notification system 1, will now be described with reference to the flowcharts shown in FIGS.

[0030] 3, the differential pressure determination unit 11 recognizes the differential pressure of the target locations (the entrance / exit 112 of the store 100 and the entrance / exit 113 of the backyard 120) based on the detection signals of the first differential pressure sensor 46 and the second differential pressure sensor 47. Note that the entrance / exit 131 of the truck yard 130, whose differential pressure is recognized based on the detection signal of the third differential pressure sensor 48, may also be included in the target locations.

[0031] In the following step S2, the differential pressure determination unit 11 determines whether or not there is a target location where the differential pressure is negative, based on the detection results of the first differential pressure sensor 46 and the second differential pressure sensor 47. If there is a target location where the differential pressure is negative (first space negative pressure state), the differential pressure determination unit 11 proceeds to step S3, and if there is no target location where the differential pressure is negative (first space positive pressure state), the differential pressure determination unit 11 proceeds to step S20.

[0032] In step S3, the display control unit 16 causes the display device 50 to display a notification screen exemplified in FIG. 6 or FIG. 7 according to the target location where the differential pressure is negative. In addition, in step S20, the display control unit 16 causes the display device 50 to display a notification screen exemplified in FIG. 8. The notification screens in FIG. 6 to FIG. 8 include a store management image 350 showing the management status of the store 100, and a first air current display image 301 or a second air current display image 300. The store management image 350 shows the status of the air flow (inflow: ×, outflow: ◯), kitchen time (on schedule: ◯, off schedule: ×), sales floor temperature and humidity (temperature detected by the temperature sensor 40 and humidity sensor 41), kitchen exhaust-supply air interlocking (interlocking: ◯, kitchen exhaust only: ×), door (open detection: check required, closed detection: ◯), and sales floor CO2 concentration (concentration detected by the CO2 sensor 42).

[0033] 6 is an example of a notification screen displayed on the display device 50 by the display control unit 16 in step S3 when the pressure difference determination unit 11 determines that the air pressure in the sales floor 110 is more negative than the air pressure in the truck yard 130 based on the detection signal of the second pressure difference sensor 47. In the notification screen of FIG. 6, a second airflow display image 300 is displayed on a layout map 310 of the store 100, in which icons 311, 312 indicating a state in which air flows from the back yard 120 to the sales floor 110 (a state in which air flows into the sales floor 110) are superimposed at positions corresponding to the entrances 114, 115 between the back yard 120 and the sales floor 110 that communicate with the truck yard 130. Note that an example of a case in which the air pressure in the sales floor 110 becomes more negative than the air pressure in the truck yard 130 is a case in which the second ventilation device 70b is operating, which supplies air returned from the sales floor 110 to the truck yard 130.

[0034] 7 is an example of a notification screen displayed on the display device 50 by the display control unit 16 in step S3 when the pressure difference determination unit 11 determines that the air pressure in the sales floor 110 is more negative than the outdoor air pressure based on the detection signal of the first pressure difference sensor 46. In the notification screen of FIG. 7, a second airflow display image 300 is displayed on a layout map 310 of the store 100, in which icons 313, 314 indicating a state in which air flows from the outdoors toward the sales floor 110 (a state in which air flows into the sales floor 110) are superimposed at positions corresponding to the entrances 111, 112 of the store 100 that communicate the sales floor 110 with the outdoors. Note that an example of a case in which the air pressure in the sales floor 110 becomes more negative than the outdoor air pressure is a case in which the first ventilation device 70a that supplies outdoor air to the sales floor 110 is stopped and no air is supplied from the outdoors to the sales floor 110.

[0035] 8 is an example of a notification screen displayed on the display device 50 by the display control unit 16 in step S20 when the differential pressure determination unit 11 determines that the air pressure in the sales floor 110 is not more negative than the outdoor air pressure and the backyard 120 based on the detection signals of the first differential pressure sensor 46 and the second differential pressure sensor 47. The notification screen in FIG. 8 displays a first airflow display image 301 in which icons 320, 321, 322, and 323 indicating that air is flowing from the sales floor 110 toward the backyard 120 or the outdoor air (air is flowing out from the sales floor 110) are superimposed on a layout map 310 of the store 100 at positions corresponding to the entrances 114 and 115 between the backyard 120 communicating with the truck yard 130 and the sales floor 110, and at positions corresponding to the entrances 111 and 112 of the store 100 communicating between the sales floor 110 and the outdoor air. By displaying the first air current display image 301 on the display device 50, it is possible to notify the manager A1 that the sales floor 110 is in a normal state, with air flowing out of the sales floor 110.

[0036] 6 and 7, by displaying the second air current display image 300 on the display device 50, the manager A1 can be made aware that air may be flowing into the sales floor 110, and can be prompted to take action such as checking whether the doors 113a, 114a of the entrances 113, 114 are open. Note that the icons 311-314, 320-323 only need to indicate the direction of the air current, and may be in a form other than an arrow, such as showing the flow by animation.

[0037] In the following step S4, the ventilation device operation recognition unit 13 recognizes the operation status of the first ventilation device 70a, the second ventilation device 70b, and the exhaust devices 121-124 based on the operation state information input from the first ventilation device 70a, the second ventilation device 70b, and the exhaust devices 121-124. In the next step S5, the display control unit 16 judges whether or not the ventilation device operation recognition unit 13 recognizes that the first ventilation device 70a is stopped. Then, when the first ventilation device 70a is stopped, the display control unit 16 advances the process to step S30, and when the first ventilation device 70a is operating, the display control unit 16 advances the process to step S6. In step S30, the display control unit 16 causes the display device 50 to display an "air supply request image", and advances the process to step S6. The "air supply request image" may be displayed by additionally displaying an image prompting the user to start air supply operation of the first ventilation device 70a in the store management image 350, or may be displayed as a notification image 351 separate from the store management image 350, as shown in Figures 6 and 7.

[0038] In step S6, the display control unit 16 starts a timer for monitoring the continuation of the first space negative pressure state. The set time of the timer is, for example, the opening time of the doors required for entering and exiting the store entrance 111 and the store entrance 112, and is determined in advance by a previous test or simulation. The set time of the timer is, for example, 20 seconds. In the following step S7, the differential pressure determination unit 11 recognizes the differential pressure of the target locations (entrances 112, 113) in the same manner as in step S1. In the next step S8, the display control unit 16 judges whether or not there is a target location where the differential pressure is negative. Then, if there is a target location where the differential pressure is negative (if the first space negative pressure state), the display control unit 16 proceeds to the process of step S9, and if there is no target location where the differential pressure is negative (if the first space positive pressure state), the display control unit 16 proceeds to the process of step S1.

[0039] In step S9, the display control unit 16 judges whether the timer has timed out. If the timer has timed out, the display control unit 16 advances the process to step S10 in Fig. 4, and if the timer has not timed out, the display control unit 16 advances the process to step S7. In step S10 in Fig. 4, the door opening / closing recognition unit 12 recognizes the opening / closing states of the doors 112a, 131a based on the detection signals of the first door opening / closing sensor 44 and the second door opening / closing sensor 45.

[0040] In the next step S11, the display control unit 16 judges whether or not there is a door that has been recognized as being open by the door open / closed recognition unit 12. If there is a door that has been recognized as being open, the display control unit 16 advances the process to step S40, and if there is no door that has been recognized as being open, the display control unit 16 advances the process to step S12. In step S40, the display control unit 16 causes the display device 50 to display a "door open / closed confirmation image" that prompts the user to confirm which door is open, and advances the process to step S12.

[0041] 6 and 7, the "door open / close confirmation image" may be displayed by displaying the name of the door (door 112a or door 131a) that has been recognized as being open together with the display "Door: Confirmation Required" on the store management image 350, or may be displayed separately from the store management image 350. Also, an image indicating that the door is in an open state may be displayed at a position corresponding to the door that has been recognized as being in an open state on the second airflow display image 300.

[0042] In step S12, the display control unit 16 causes an "abnormality notification image" to be displayed on the display device 50. As shown in Figs. 6 and 7, the "abnormality notification image" is displayed by displaying "Air flow: x" on the store management image 350 and by displaying arrow icons 311, 312, 313, and 314 indicating the inflow of air into the sales floor 110 in positions on the second airflow display image 300 corresponding to the entrances / exits 111, 112, 113, and 114 which are communication points through which air may be flowing into the sales floor 110. Note that, apart from the store management image 350, an "abnormality notification image" that notifies of an abnormality in the air flow at the communication points may be displayed on the display device 50.

[0043] [3. Effects, etc.] As described above, in this embodiment, when the alarm system 1 recognizes that the sales floor 110 is in a first space negative pressure state where the sales floor 110 is under negative pressure due to the pressure difference at the entrance / exit 112 of the sales floor 110 in the store 100 and the pressure difference at the entrance / exit 113 of the back yard 120, it displays an abnormality alarm image on the display device 50 to alert the user to an abnormality in the air flow at the entrances / exits 112, 113. In this way, the notification system 1, with a simple configuration, can detect the inflow of outside air into the sales floor 110 of the store 100 and notify the user that measures are required.

[0044] (Other embodiments) As described above, the above embodiment has been described as an example of the technology disclosed in the present application. However, the technology in the present disclosure is not limited to this, and can be applied to embodiments in which modifications, substitutions, additions, omissions, etc. are made.

[0045] In the above embodiment, a configuration was shown in step S5 of FIG. 4 in which an air supply request image is displayed in step S30 when the first ventilation device 70a is stopped (air supply OFF). However, the technology of the present disclosure is not limited to this, and a configuration may also be used in which an image is displayed to encourage an increase in the air volume (air supply volume) of the first ventilation device 70a when the sales floor 110 is at negative pressure and the ventilation air volume of the first ventilation device 70a is below a predetermined value.

[0046] In the above embodiment, a case has been described in which sales floor 110 of store 100 is adjacent to the outdoors via doors 111a, 112a. However, in cases where a connecting passageway exists between sales floor 110 and the outdoors, and a door is provided in the connecting passageway to connect sales floor 110 to the outdoors via the connecting passageway, a differential pressure sensor may be provided near the door provided in the connecting passageway.

[0047] In the above embodiment, a notification screen showing the air flow in the sales floor 110, as shown in Figures 5 and 6, is displayed on the display device 50 by processing according to the flowcharts shown in Figures 3 and 4. As another embodiment, data for the notification screen may be sent to the mobile terminal 60 used by the manager A2 shown in Figure 2, thereby causing the notification screen to be displayed on the display unit of the mobile terminal 60.

[0048] In the above embodiment, as shown in FIG. 5, when the sales floor 110 is at negative pressure (first space negative pressure state), a door open / close confirmation image is displayed on the display device 50 in the store management image 350 to prompt the user to check whether the door to the store 100 is open or closed, but this display may be omitted.

[0049] In the above embodiment, when the sales floor 110 is at negative pressure (first space negative pressure state) and the ventilation device 70 is stopped, an air supply request image prompting the ventilation device 70 to supply air to the sales floor 110 is displayed on the display device 50, but this display may be omitted.

[0050] In the above embodiment, as shown in steps S10-S11 and S40 in FIG. 4, when the sales floor 110 is at negative pressure (first space negative pressure state), as shown in FIG. 5, a door open / close confirmation image is displayed on the store management image 350 to prompt the user to check whether the door is open or closed. However, if the ventilation device 70 is stopped, this display may not be displayed.

[0051] Also, if the sales floor 11 is under negative pressure, the door confirmation display may be displayed without detecting whether the door is open or closed. This allows a store system that does not have a door open / close sensor to urge the user to be careful when opening and closing the door so that air does not enter the sales floor when the sales floor is under negative pressure. Also, when the sales floor 110 is under negative pressure and the first ventilation device 70a is stopped, a message may be displayed to prompt the customer to check both the first ventilation device 70a and the door.

[0052] In the above embodiment, in step S2 of Fig. 4, if the state in which the differential pressure is negative continues for a predetermined time or more, it may be determined that there is a target location where the differential pressure is negative. This makes it possible to prevent erroneous determination due to temporary opening of a door, etc.

[0053] In the above embodiment, when an open door is recognized by the processing of steps S10, S11, and S40 in Fig. 5, a display is displayed to encourage confirmation of the open door, but when it is determined in step S2 in Fig. 4 that there is no target location where the differential pressure is negative, the process branches to step S20. Therefore, when the pressure in the sales floor 110 is higher than the surrounding area (outdoors, back yard 120), the "door open / close confirmation image" is not displayed in step S40 even if the first door open / close sensor 44 or the second door open / close sensor 45 detects that the door 112a or the door 131a is open.

[0054] In the above embodiment, even when it is determined in step S5 of Fig. 4 that the first ventilation device 70a is stopped by the process according to the flowchart shown in Fig. 4 and Fig. 5, the open / closed states of the doors 112a, 113a are confirmed in steps S10 and S11 of Fig. 5, and a "door open / close confirmation image" is displayed in step S40. As another embodiment, when it is determined that the first ventilation device 70a is stopped, an "air supply request image" that prompts the user to operate the first ventilation device 70a may be displayed without displaying the "door open / close confirmation image".

[0055] In the above embodiment, if the detection result of the first differential pressure sensor 46 or the second differential pressure sensor 47 indicates that the pressure is lower in the sales floor 110 than outdoors or the back yard 120, and the concentration of the target airborne substance recognized by the airborne substance concentration recognition unit 14 is equal to or higher than a predetermined concentration, the display device 50 may display a message indicating that predetermined measures (such as restricting the use of the entrances and exits of the sales floor 110) are necessary.

[0056] In the above embodiment, an alert may be displayed on the display device 50 when "the sales floor 110 has a more negative pressure than the outdoors" and "the sales floor 110 has a more negative pressure than the backyard 120." This corresponds to a situation where the first ventilation device 70a that supplies outdoor air to the sales floor 110 is stopped and no air is being supplied to the sales floor 110, so the sales floor 110 has a more negative pressure than the outdoors, or a situation where the second ventilation device 70b that returns air from the sales floor 110 to the backyard 120 is operating and the amount of exhaust air from the sales floor 110 is large, so the sales floor 110 has a more negative pressure than the backyard 120.

[0057] In the above embodiment, it is preferable that the work spaces 160, 161 have a positive pressure compared to the back yard 120 (here, the space in the back yard 120 other than the work spaces 160, 161). This is because if the work spaces 160, 161 have a negative pressure compared to the back yard 120, cold air containing humidity or cold air from the sales floor 110 will flow into the work spaces 160, 161, and there is a risk of condensation forming in a prefabricated refrigerator placed in the work spaces 160, 161 or in the ceiling of the work spaces 160, 161.

[0058] 9, a fourth differential pressure sensor 49 is provided to detect the pressure difference between the backyard 120 and the work spaces 160, 161, and when the detection value of the fourth differential pressure sensor 49 indicates that the work spaces 160, 161 are more positive pressure than the backyard 120, an alert is not displayed on the display device 50, and when the detection value of the fourth differential pressure sensor 49 indicates that the backyard 120 is more positive pressure than the work spaces 160, 161, an alert is displayed on the display device 50. Also, when the work spaces 160, 161 are more negative pressure than the backyard 120 and the second ventilation device 70b that returns air to the work spaces 160, 161 is stopped, a display recommending that the second ventilation device 70b be operated may be displayed.

[0059] If the pressure inside the sales floor 110 is negative, the cause of the alert may be an open window, equipment malfunction, a clogged filter, an open outdoor door, or the like. Also, an airflow detection method other than a differential pressure sensor, such as an airflow sensor or an anemometer, may be employed. In addition, the pressure difference and the air conditioning and ventilation status within the store 100 may be remotely monitored. In this case, the pressure difference and the air conditioning and ventilation status for a predetermined period (for example, one year) may be output as a report to each store owner, etc. This allows the store owner, etc. to grasp the operational status and power consumption of the store as a report.

[0060] In the above embodiment, the notification system 1 is provided in the store 100, but the notification system 1 may be configured as a system external to the store 100, such as the store management server 220. In this case, the detection information of each sensor provided in the store 100 is sent to the store management server 220, the store management server 220 executes the processing according to the flowcharts shown in Figures 3 and 4, and the data for the notification screens shown in Figures 5 and 6 is sent from the store management server 220 to the display device 50 of the store 100, causing the display device 50 to display the notification screen.

[0061] The controller that controls the operation of the notification system in the present disclosure may be any controller that can control the notification system in the present disclosure. When expressing the subject matter of the invention, the controller may be expressed as a control means, a control unit, or a similar term to the controller as the one that controls the notification system in the present disclosure. The controller can be realized in various forms. For example, a processor may be used as the controller. If a processor is used as the controller, various processes can be executed by reading a program from a storage medium that stores the program into the processor and executing the program by the processor. Therefore, the processing contents can be changed by changing the program stored in the storage medium, so that the degree of freedom in changing the control contents can be increased. Examples of the processor include a CPU (Central Processing Unit) and an MPU (Micro-Processing Unit). Examples of the storage medium include a hard disk, a flash memory, and an optical disk. In addition, a wired logic that cannot be rewritten in a program may be used as the controller. Using a wired logic as the controller is effective in improving the processing speed. Examples of the wired logic include an ASIC (Application Specific Integrated Circuit). In addition, the controller may be realized by combining a processor and a wired logic. If the controller is realized by combining a processor and wired logic, it is possible to increase the degree of freedom of software design and improve the processing speed. In addition, the controller and a circuit having a function different from that of the controller may be configured with a single semiconductor element. An example of a circuit having a different function is an A / D-D / A conversion circuit. In addition, the controller may be configured with a single semiconductor element or multiple semiconductor elements. When configured with multiple semiconductor elements, each control described in the claims may be realized with different semiconductor elements. Furthermore, the controller may be configured with a configuration including a semiconductor element and a passive component such as a resistor or a capacitor.

[0062] It should be noted that the above-described embodiments are intended to illustrate the technology of the present disclosure, and various modifications, substitutions, additions, omissions, and the like can be made within the scope of the claims or their equivalents.

[0063] (Additional Note) The above description of the embodiments discloses the following techniques.

[0064] (Technology 1) An information display system for a store, comprising: a differential pressure sensor that detects the differential pressure between the air pressure in a first space, which is a sales floor within a store, and the air pressure in a second space adjacent to the first space; and a display device used in the store, wherein when the detection result of the differential pressure sensor indicates that the first space has a lower pressure than the second space, the display device displays that the airflow conditions between the second space and the first space are abnormal. With this simple configuration, it is possible to detect a state in which there is a possibility of air flowing into the sales floor of a store and to notify the user that countermeasures are required.

[0065] (Technology 2) The display device displays a first airflow image showing the airflow from the first space to the second space, superimposed on a layout map of the store, when the detection result of the differential pressure sensor indicates that the first space is under higher pressure than the second space, and displays a second airflow image showing the airflow from the second space to the first space, superimposed on the layout map of the store, when the detection result of the differential pressure sensor indicates that the first space is under lower pressure than the second space. This is an information display system for a store described in Technology 1. With this configuration, the direction of the airflow between the first space and the second space can be displayed with good visibility.

[0066] (Technology 3) An information display system for a store as described in Technology 2, in which the display device displays the first air current image and the second air current image at a position corresponding to the communication point between the first space and the second space on the layout map. This configuration makes it possible to easily identify locations where the airflow conditions are abnormal.

[0067] (Technology 4) An information display system for a store as described in Technology 1 or Technology 2, in which, if the detection result of the differential pressure sensor indicates that the first space has a lower pressure than the second space, the display device displays a message to check the open / closed state of a door located between the first space and the second space in the store. With this configuration, when the first space has a lower pressure than the second space, the store manager or the like is prompted to check whether the door is open or closed, thereby preventing a situation in which the first space has a lower pressure than the second space due to the door being open from continuing.

[0068] (Technology 5) The information display system for a store described in Technology 4 further includes a door opening / closing sensor that detects the open / closed state of the door, and the display device displays a message to check the open / closed state of the door when the detection result of the differential pressure sensor indicates that the first space is at a lower pressure than the second space and the door opening / closing sensor detects that the door is open. According to this configuration, when the door is detected to be open and it is believed that the reason the first space has lower pressure than the second space is because the door is open, the store manager or the like is prompted to check the open / closed state of the door, thereby preventing a situation in which the first space has lower pressure than the second space due to the door being open from continuing.

[0069] (Technology 6) In an information display system for a store as described in Technology 5, when the detection result of the differential pressure sensor indicates that the first space is under higher pressure than the second space, the display device does not display a message requesting confirmation of the open / closed state of the door even if the door open sensor unit detects that the door is open. According to this configuration, even if the door is open, an air flow from the first space to the second space is generated, and abnormalities in the air flow are unlikely to occur. Therefore, it is possible to prevent unnecessary alerts from being issued in situations where there is little need to prompt the user to check the door.

[0070] (Technology 7) An information display system for a store described in any one of Technologies 1 to 6, comprising a ventilation device for ventilating the first space, and the display device further displays, when the detection result of the differential pressure sensor indicates that the first space is at a lower pressure than the second space, and when the ventilation device is stopped, a message urging the user to operate the ventilation device. According to this configuration, it is possible to urge the store manager or the like to operate the ventilation device and eliminate the state in which the first space has a lower pressure than the second space.

[0071] (Technology 8) An information display system for a store as described in Technology 7, in which the display device, when the detection result of the differential pressure sensor indicates that the pressure in the first space is lower than that in the second space and when the ventilation device is stopped, displays a message urging the user to operate the ventilation device without displaying a confirmation of the open / closed status of the door between the first space and the second space. With this configuration, when it is thought that the cause of the first space being at a lower pressure than the second space is the ventilation device being stopped, it is possible to avoid unnecessary displays that prompt the user to check the door opening / closing information.

[0072] (Technology 9) An information display system for a store described in any one of Technologies 1 to 8, further comprising an airborne substance concentration recognition unit that recognizes the concentration of a target airborne substance outdoors, wherein the display device displays a message indicating that specified measures are necessary when the detection result of the differential pressure sensor indicates that the first space is at a lower pressure than the second space and the concentration of the target airborne substance detected by the airborne substance concentration recognition unit is equal to or higher than a specified concentration. According to this configuration, when the concentration of the target airborne substance outdoors is high and it is highly necessary to prevent outside air from flowing into the sales floor, a message is displayed urging the user to take measures. This makes it possible to urge the store manager or the like to quickly take measures to resolve the condition in which the first space is at a lower pressure than the second space and to prevent the target airborne substance from flowing into the sales floor.

[0073] (Technology 10) An information display method for a store executed by a computer, in which, when a processor determines that the detection result of a differential pressure sensor that detects the differential pressure between the air pressure in a first space, which is a sales floor within a store, and a second space adjacent to the first space indicates that the pressure in the first space is lower than that in the second space, a display device used in the store displays that the airflow conditions between the first space and the second space are abnormal. By executing the store information display method having this configuration by a computer, it is possible to obtain the same effects as the store information display system of Technique 1.

[0074] (Technology 11) A program that causes a processor of a display terminal used in a store to function in such a way that, when the detection result of a differential pressure sensor that detects the differential pressure between the air pressure in a first space, which is a sales floor within a store, and a second space adjacent to the first space indicates that the pressure in the first space is lower than that in the second space, the program causes the display terminal to display a message indicating that the airflow conditions between the first space and the second space are abnormal. The configuration of technique 1 can be realized by executing the program of this configuration by a processor. [Industrial Applicability]
