Description

Aspects of the present invention generally relate to cigarettes and toilet management systems.

Toilet paper in public spaces may not have replacement toilet paper to prevent theft. In such a case, a manager such as a cleaning staff regularly patrols to replenish the toilet paper.

However, in such a method, in order to prevent the state where there is no toilet paper, it is necessary to increase the patrol frequency of the administrator, which increases the burden on the administrator. In addition, such a method is inefficient because the administrator needs to patrol and inspect the toilet booths that do not require replacement of toilet paper. In particular, in Japan, there are concerns about labor shortages due to the declining population in the future, so a toilet management system that can efficiently replace toilet paper is becoming more and more important.

In Patent Document 1, a light emitting diode and a light receiving sensor are provided at opposite positions inside a folder for storing toilet paper, and the light receiving sensor receives light from the light emitting diode blocked by the toilet paper, so that the rest of the toilet paper remains. A device for detecting that the amount has fallen below a predetermined amount has been proposed. However, since such a device uses a transmissive sensor, it can only detect whether or not the remaining amount of toilet paper is less than a predetermined amount, and the remaining amount of toilet paper gradually decreases. Cannot be detected. That is, it is not possible to detect a detailed change in the remaining amount of toilet paper.

The reflection type sensor 30 detects the remaining amount of toilet paper TP by utilizing the reflection of electromagnetic waves. The reflection type sensor 30 is, for example, a photoelectric sensor such as an infrared sensor or a radio wave sensor such as a microwave sensor or a millimeter wave sensor. The position where the reflection sensor 30 is provided will be described later. The reflection type sensor 30 includes an electromagnetic wave transmitting unit 31 and an electromagnetic wave receiving unit 32.

The reflection type sensor 30 detects the remaining amount of the toilet paper TP by detecting the intensity of the electromagnetic wave received by the electromagnetic wave receiving unit 32. When the remaining amount of the toilet paper TP is larger than the predetermined amount, the intensity of the electromagnetic wave received by the electromagnetic wave receiving unit 32 is larger than the predetermined value. When the remaining amount of the toilet paper TP is less than the predetermined amount, the intensity of the electromagnetic wave received by the electromagnetic wave receiving unit 32 is smaller than the predetermined value.

The information transmission unit 40 transmits information about the detection result of the reflection sensor 30 to the external device 200. The information transmission unit 40 is electrically connected to the electromagnetic wave reception unit 32 of the reflection sensor 30.

The operation of the reflection sensor 30 and the information transmission unit 40 is controlled by, for example, a control unit. The control unit controls, for example, the cycle of the sensing operation in the reflection sensor 30, the timing of transmitting information from the information transmission unit 40, and the like. Any one of the reflection sensor 30, the information transmitting unit 40, and the control unit may have a receiving unit that receives a signal from the external device 200.

The outer shell 20 has, for example, a battery mounting portion for mounting a battery. The reflection sensor 30, the information transmission unit 40, and the control unit may operate by receiving electric power from an external power source supplied via an outlet. In this case, the battery mounting portion can be omitted.

The paper cutting board 50 is used when the user cuts the toilet paper TP. The paper cutting board 50 is provided above the toilet paper TP. That is, the paper cutting plate 50 is provided above the holding portion 10. The paper cutting plate 50 is rotatably supported on the side plate 22 and the upper portion of the side plate 23 of the outer shell 20.

3A and 3B are a front view and a side sectional view schematically showing the cigarette according to the embodiment.
FIG. 3B is a cross-sectional view taken along the line A1-A2 shown in FIG. 3A.
As shown in FIGS. 3A and 3B, in this example, the reflection sensor 30 is provided behind the holding portion 10. Further, in this example, the reflection type sensor 30 is provided below the holding portion 10. More specifically, in this example, the reflective sensor 30 is a wall surface WL of the toilet booth, and is provided below the back plate 21 of the outer shell 20 located behind the holding portion 10. For example, if the back plate 21 extends below the toilet paper TP, the reflective sensor 30 may be provided below the back plate 21.

Further, in this example, the reflection sensor 30 is provided at a position overlapping the center of the cigarette 100 in the left-right direction. The reflection sensor 30 may be provided at a position that does not overlap with the center of the cigarette 100 in the left-right direction.

Further, in this example, the reflection type sensor 30 is provided so that the central axis CL of the electromagnetic wave transmitted from the electromagnetic wave transmitting unit 31 faces diagonally upward. Here, the "obliquely upward" is a direction including at least an upper component and a front component. The "diagonally upward" may be a direction including a left-right component in addition to the upper component and the front component.

Further, in this example, the reflection type sensor 30 is provided so that the central axis CL of the electromagnetic wave transmitted from the electromagnetic wave transmitting unit 31 deviates from the axial center AX of the toilet paper TP. The reflection sensor 30 is provided so that the central axis CL of the electromagnetic wave transmitted from the electromagnetic wave transmitting unit 31 does not face the core of the toilet paper TP. More specifically, the reflection sensor 30 is provided so that the central axis CL of the electromagnetic wave transmitted from the electromagnetic wave transmitting unit 31 faces downward from the axial center AX of the toilet paper TP. As a result, the reflective sensor 30 detects the remaining amount in the portion of the toilet paper TP below the axis AX.

4 (a) and 4 (b) are a front view and a side sectional view schematically showing a cigarette according to a modified example of the embodiment.
FIG. 4B is a cross-sectional view taken along the line B1-B2 shown in FIG. 4A.
As shown in FIGS. 4 (a) and 4 (b), in this example, the reflective sensor 30 is provided on the upper portion of the back plate 21 of the outer shell 20 located behind the holding portion 10. As described above, the reflection type sensor 30 may be provided behind the holding portion 10 and above the holding portion 10.

Further, in this example, the reflection sensor 30 is provided so that the central axis CL of the electromagnetic wave transmitted from the electromagnetic wave transmitting unit 31 faces upward from the axial center AX of the toilet paper TP. In this way, the reflective sensor 30 may detect the remaining amount in the portion above the axis AX of the toilet paper TP.

Hereinafter, the operations of the toilet management system 500 and the cigarette 100 according to the embodiment will be described.
FIG. 5 is a flowchart showing an example of the operation of the cigarette of the toilet management system according to the embodiment.
FIG. 6 is a flowchart showing an example of the operation of the external device of the toilet management system according to the embodiment.

As shown in FIG. 5, when the flow is started, the control unit of the cigarette 100 performs a sensing operation by the reflection sensor 30 (step S101). In the sensing operation, the reflection type sensor 30 transmits an electromagnetic wave from the electromagnetic wave transmitting unit 31 toward the toilet paper TP, and receives the electromagnetic wave transmitted from the electromagnetic wave transmitting unit 31 and reflected by the toilet paper TP in the electromagnetic wave receiving unit 32.

The reflection type sensor 30 continuously transmits and receives electromagnetic waves a plurality of times (for example, 10 times) per sensing operation. By transmitting and receiving electromagnetic waves multiple times, the occurrence of false positives can be suppressed. The reflection sensor 30 uses, for example, the average value of the intensities of a plurality of received electromagnetic waves as the intensity of the electromagnetic waves received in one sensing operation. Alternatively, the reflection type sensor 30 uses, for example, a value having the same intensity for a predetermined number of times among the intensities of a plurality of received electromagnetic waves as the intensity of the electromagnetic wave received in one sensing operation. Alternatively, for example, when the intensity of a plurality of received electromagnetic waves falls within a certain range, the reflection type sensor 30 sets the median value between the maximum value and the minimum value as the intensity of the electromagnetic wave received in one sensing operation. To do. Hereinafter, the intensity of the electromagnetic wave received in one sensing operation is referred to as "the intensity of the received electromagnetic wave".

When the intensity of the received electromagnetic wave exceeds a predetermined value (step S102: No), the control unit ends the flow. That is, when the intensity of the received electromagnetic wave exceeds a predetermined value, it is determined that the remaining amount of the toilet paper TP exceeds the predetermined amount and the replacement of the toilet paper TP is unnecessary. The predetermined value is, for example, a value smaller than the second threshold value TH2 described later. The predetermined value is, for example, the strength when the remaining amount of toilet paper TP is 15%.

When the intensity of the received electromagnetic wave is equal to or less than a predetermined value (step S102: Yes), the control unit changes the period of the sensing operation (step S103). The change of the sensing operation cycle will be described later.

When the cycle of the sensing operation is changed, the control unit transmits information about the detection result of the reflection sensor 30 from the information transmission unit 40 to the external device 200 (step S104). As described above, in this example, when the intensity of the received electromagnetic wave becomes equal to or less than a predetermined value, the information transmission unit 40 transmits information about the detection result of the reflection sensor 30 to the external device 200. That is, when the intensity of the received electromagnetic wave is not more than a predetermined value, the remaining amount of the toilet paper TP is not more than the predetermined amount, and it is determined that the toilet paper TP needs to be replaced.

On the other hand, as shown in FIG. 6, the external device 200 waits until it receives the information from the information transmission unit 40 of the cigarette 100 (step S201: No). Upon receiving the information from the information transmission unit 40 (step S201: Yes), the external device 200 notifies the replacement time of the toilet paper TP (step S202).

Hereinafter, the effects of the cigarette 100 and the toilet management system 500 according to the embodiment will be described.
As described above, for example, when an attempt is made to detect the remaining amount of toilet paper using a transmissive sensor, there is a problem that a detailed change in the remaining amount of toilet paper cannot be detected. On the other hand, in the embodiment, by providing the reflection type sensor 30, it is possible to detect a detailed change in the remaining amount of the toilet paper TP. That is, in the embodiment, it can be detected that the remaining amount of the toilet paper TP is gradually reduced. As a result, the administrator can replace the toilet paper TP more efficiently.

Further, in the embodiment, the reflection type sensor 30 is provided so that the central axis CL of the electromagnetic wave transmitted from the electromagnetic wave transmitting unit 31 deviates from the axis AX of the toilet paper TP, so that the remaining amount of the toilet paper TP can be detailed. A change can be detected, and when the remaining amount of toilet paper TP becomes less than a predetermined amount, the intensity of the electromagnetic wave received by the electromagnetic wave receiving unit 32 is greatly reduced, so that the remaining amount of toilet paper TP is more reliably reduced. Can be detected.

Further, in the embodiment, an information transmitting unit 40 for transmitting information about the detection result of the reflection sensor 30 to the external device 200 is provided, and when the intensity of the electromagnetic wave received by the electromagnetic wave receiving unit 32 becomes equal to or less than a predetermined value, the external device is provided. 200 notifies when it is time to replace the toilet paper. As a result, it is possible to notify the administrator outside the toilet booth of the replacement time of the toilet paper TP via the external device 200. Therefore, the patrol for inspection by the administrator becomes unnecessary, and the toilet paper TP can be replaced efficiently. Further, as a result, the possibility of running out of paper can be reduced, and the toilet space can be made convenient for the user who uses the toilet.

Further, in the embodiment, by providing the reflective sensor 30 behind the holding portion 10, it is possible to prevent the reflective sensor 30 from receiving unintended interference from the user's hand or the like, and more accurately the toilet paper TP. It is possible to detect the remaining amount of.

Further, when the paper winder 100 includes the paper cutting plate 50 or the top plate 60, the paper dust generated from the toilet paper TP tends to collect between the paper cutting plate 50 or the top plate 60 and the toilet paper TP. If the reflective sensor 30 is provided at a location where paper dust tends to collect, the detection accuracy may decrease due to the influence of the paper dust. On the other hand, in the embodiment, by providing the reflective sensor 30 below the holding portion 10, even when the cigarette 100 includes the paper cutting plate 50 and the top plate 60, the reflective sensor 30 is made of paper dust. It is possible to suppress the influence of. As a result, the remaining amount of toilet paper TP can be detected more accurately. Further, by providing the reflective sensor 30 below the holding portion 10, maintenance of the reflective sensor 30 can be easily performed even while the toilet paper TP is attached to the holding portion 10.

Further, in the embodiment, by providing the reflection sensor 30 so that the central axis CL of the electromagnetic wave transmitted from the electromagnetic wave transmitting unit 31 faces diagonally upward, even when the remaining amount of the toilet paper TP becomes low, The remaining amount of toilet paper TP can be detected more accurately.

Hereinafter, a modified example of the operation of the toilet management system 500 and the cigarette 100 according to the embodiment will be described.
7 (a) and 7 (b) are flowcharts showing another example of the operation of the cigarette of the toilet management system according to the embodiment.
FIG. 8 is a flowchart showing another example of the operation of the external device of the toilet management system according to the embodiment.

As shown in FIG. 7A, in this example, when the flow is started, the control unit of the cigarette 100 performs a sensing operation by the reflection sensor 30 (step S301), and the information transmission unit 40 to the external device 200 Information about the detection result of the reflection sensor 30 is transmitted to (step S302). That is, in this example, the information transmission unit 40 transmits information about the detection result of the reflection sensor 30 to the external device 200 regardless of the intensity of the received electromagnetic wave.

On the other hand, as shown in FIG. 8, the external device 200 waits until it receives the information from the information transmission unit 40 of the cigarette 100 (step S401: No). Upon receiving the information from the information transmitting unit 40 (step S401: Yes), the external device 200 determines whether or not the intensity of the electromagnetic wave received by the electromagnetic wave receiving unit 32 exceeds a predetermined value (step S402).

When the intensity of the received electromagnetic wave exceeds a predetermined value (step S402: No), the external device 200 ends the flow. That is, when the intensity of the received electromagnetic wave exceeds a predetermined value, it is determined that the remaining amount of the toilet paper TP exceeds the predetermined amount and the replacement of the toilet paper TP is unnecessary.

When the intensity of the received electromagnetic wave is equal to or less than a predetermined value (step S402: Yes), the external device 200 transmits a signal for changing the cycle of the sensing operation to the cigarette 100 (step S403).

When the signal is transmitted to the cigarette 100, the external device 200 notifies the replacement time of the toilet paper TP (step S404). That is, when the intensity of the received electromagnetic wave is not more than a predetermined value, the remaining amount of the toilet paper TP is not more than the predetermined amount, and it is determined that the toilet paper TP needs to be replaced.

As shown in FIG. 7B, the control unit of the cigarette 100 waits until it receives a signal from the external device 200 (step S501: No). Upon receiving the signal for changing the sensing operation cycle from the external device 200 (step S501: Yes), the control unit changes the sensing operation cycle (step S502). The change of the sensing operation cycle will be described later.

As described above, in the embodiment, the determination of whether or not the intensity of the received electromagnetic wave exceeds a predetermined value may be performed by the cigarette 100 or the external device 200.

Hereinafter, the cycle change of the sensing operation by the reflection sensor 30 will be described.
FIG. 9 is a flowchart showing a part of the operation of the cigarette of the toilet management system according to the embodiment.
FIG. 10 is a timing chart showing an example of the cycle of the sensing operation in the cigarette according to the embodiment.

The maximum value Rmax of the intensity of the electromagnetic wave (reflected wave) is the intensity when the remaining amount of the toilet paper TP is 100%. The minimum value Rmin of the intensity of the electromagnetic wave (reflected wave) is the intensity when the remaining amount of the toilet paper TP is 0%.

As shown in FIGS. 9 and 10, when the intensity of the received electromagnetic wave is equal to or higher than the first threshold value TH1 (step S601: No), the reflection sensor 30 performs a sensing operation in the first cycle P1 (step). S602). The first cycle P1 is, for example, 60 minutes. The first threshold value TH1 is, for example, the intensity of the electromagnetic wave (reflected wave) when the thickness from the core to the outer circumference of the toilet paper TP becomes 3/4 of the thickness when the remaining amount is 100%. When the intensity of the received electromagnetic wave is the first threshold value TH1, the remaining amount of toilet paper TP is, for example, about 50%.

When the intensity of the received electromagnetic wave is less than the first threshold value TH1 (step S601: Yes) and equal to or higher than the second threshold value TH2 (step S603: No), the reflection sensor 30 performs a sensing operation in the second cycle P2. (Step S604). The second period P2 is shorter than the first period P1. The second cycle P2 is, for example, 10 minutes. The second threshold value TH2 is, for example, the intensity of the electromagnetic wave (reflected wave) when the thickness from the core to the outer circumference of the toilet paper TP is halved of the thickness when the remaining amount is 100%. When the intensity of the received electromagnetic wave is the second threshold value TH2, the remaining amount of toilet paper TP is, for example, about 25%.

When the intensity of the received electromagnetic wave is less than the second threshold value TH2 (step S603: Yes), the reflection sensor 30 performs the sensing operation in the third cycle P3 (step S605). The third period P3 is shorter than the second period P2. The third cycle P3 is, for example, 1 minute.

As described above, when the intensity of the received electromagnetic wave is high (first threshold TH1 or more), the reflection type sensor 30 performs the sensing operation in a long cycle (first cycle P1), and the intensity of the received electromagnetic wave is low (second cycle). When the threshold value is TH2 or more and less than the first threshold value TH1, the sensing operation is performed in a short cycle (second cycle P2). As a result, the amount of electricity used for the sensing operation can be reduced when the remaining amount of the toilet paper TP is large with simple control. Therefore, the power consumption can be suppressed as compared with the case of using the transmission type sensor.

Further, when the intensity of the received electromagnetic wave is further small (less than the second threshold value TH1), the reflection type sensor 30 performs the sensing operation in a shorter cycle (third cycle P3). This reduces the amount of electricity used for the sensing operation when the remaining amount of toilet paper TP is high with simple control, and more reliably detects the remaining amount of toilet paper TP when the remaining amount of toilet paper TP is low. be able to.

Further, as shown in FIG. 10, when the intensity of the received electromagnetic wave reaches the minimum value Rmin, the reflection sensor 30 may return the sensing operation cycle to the first cycle P1. Alternatively, when the intensity of the received electromagnetic wave reaches the minimum value Rmin, the reflection type sensor 30 may make the period of the sensing operation longer than the first period P1 or stop the sensing operation. As a result, the amount of electricity used for the sensing operation can be reduced when the remaining amount of toilet paper TP is exhausted.

As described above, according to the embodiment, the cigarette and toilet management can detect a detailed change in the remaining amount of toilet paper and notify the administrator outside the toilet booth when to replace the toilet paper. The system can be provided.
