Description

Regarding the toilet booth long-stay deterrent device that deters the long-term stay of users who use the toilet booth.

In recent years, it has become a problem that users occupy public toilets such as toilets in station premises and toilet booths in office toilets for a long time.

The reasons for this are non-urgent work (such as participation in SNS and online games) and excretion (convenience) using smartphones and handheld game consoles with the spread of smartphones and handheld game consoles. A toilet booth is used as a place to perform unrelated work. That is, by using the toilet booth instead of a private room for work, the time occupied is extended.

For this reason, all toilet booths tend to be in use, and there are many situations in which people who really want to finish their stools cannot use the toilet booth and are kept waiting.

Therefore, Japanese Patent Application Laid-Open No. 2015-218571 (Patent Document 1) informs the occupants (users) in the toilet booth that there is a person waiting for the toilet, waiting for the toilet to be used. The automatic display is disclosed. The automatic display waiting for use of the toilet described in Patent Document 1 is provided with a contact-type or non-contact-type detection device for detecting the presence or absence of a person waiting for vacancy on the wall surface or the like in the toilet room, and is linked to the detection device. By installing such a display in the toilet booth, when a person waiting for a vacancy in the toilet is detected, the display in the toilet booth informs the user that there is a person waiting for a vacancy. Is.

Further, Japanese Patent Application Laid-Open No. 2002-188204 (Patent Document 2) discloses a public toilet booth system applied to a multifunctional type toilet booth provided with an automatic door. The public toilet booth system described in Patent Document 2 occupies the toilet booth for a long time to prevent the toilet booth from being occupied for the purpose of criminal acts, etc., and an accident in the toilet booth. In order to make it easier to detect the collapse of a suddenly ill person due to such factors, a sensor that detects the presence or absence of a human body in the toilet booth is provided. A technique for unlocking an automatic door and opening the automatic door when a continuous human body detection state continues for a set time or longer by the sensor is disclosed.

Further, in Japanese Patent Application Laid-Open No. 2002-048884 (Patent Document 3) and Japanese Patent Application Laid-Open No. 2010-281615 (Patent Document 4), a person who has a private room of a toilet used by an unspecified number of people waiting outside the private room. It is disclosed that a timer for notifying the elapsed time of using a private room with a count-up display is provided.

First, the timer device described in Patent Document 3 includes a display unit that displays a preset timer time, a time setting switch that sets the timer time, a start switch that starts the timer timing operation, and a timer measurement operation. It is provided with a sounding unit that generates a notification sound when the timer is completed, an fragrance generating unit that injects an fragrance agent when the timer's timing operation is completed, and a control circuit that controls each of these elements. Then, when the timekeeping operation of the timer device is completed, the fragrance is generated to prevent the user from staying in the toilet or bathroom for a long time.

Further, the timer described in Patent Document 4 uses a magnet type sensor of NC contact (switch is turned on when closed) for the door open / close sensor. Then, the timer is counted up only when the private room door is closed and the sensor is ON. As a result, the person waiting outside recognizes the time until the private room (toilet booth) of the toilet becomes vacant, so that it is possible to call attention to the user for a long time and recognize the usage time. Then, the person waiting outside can see the count-up and decide whether or not to move to another toilet.

Japanese Unexamined Patent Publication No. 2015-218571 Japanese Unexamined Patent Publication No. 2002-188204 JP-A-2002-048884 Japanese Unexamined Patent Publication No. 2010-281615

First, the toilet booth long-stay restraint device 10 according to the first embodiment of the present invention will be described with reference to the drawings. FIG. 1 schematically shows an example of an installed state of the toilet booth long-stay deterrent device according to the present invention and a state in which a user operates a portable information device. FIG. 2 is a configuration diagram of the toilet booth long-stay restraint device 10 according to the first embodiment of the present invention.

The toilet booth long-stay restraint device 10 according to the first embodiment of the present invention is a ceiling concealment type and is installed on the ceiling portion F of the toilet booth A. The entry detection unit 11a detects biological information indicating whether or not the user C is present in the toilet booth A, and outputs the biological information as a detection signal to the amplification unit 11b. Then, the amplification unit 11b amplifies the detection signal, performs level conversion, and outputs the detection signal to the control unit 13 as an entry detection signal.

Further, the photoelectric conversion unit 12a converts the light incident from the toilet booth A into a photodetection signal in order to determine whether or not the portable information device D is used. Then, the amplification unit 12b amplifies the light detection signal, performs level conversion, and outputs the light detection signal to the control unit 13 as a photoelectric conversion signal.

The control unit 13 determines the entry of the user C based on the entry detection signal, and determines whether or not the mobile information device D is used based on the photoelectric conversion signal.

Further, the control unit 13 calculates the time after detecting the entry of the user C (hereinafter, referred to as "elapsed time of entry"), and the portable information device D is used based on the photoelectric conversion signal. Calculate the accumulated time (hereinafter referred to as "equipment usage time").

Then, when the elapsed time of entering the room and the usage time of the device have passed the set times (each predetermined time), the control unit 13 outputs the light source drive condition data to the light source drive unit 14a. The lighting of the light source 14b for suppressing the use of information equipment is controlled by using the light source drive condition data.

Since the information device use suppression light source 14b effectively suppresses the use of the information device use D based on the light source drive condition data, the light source drive unit 14a lights the information device use suppression light source 14b. Generate a waveform.

The light source 14b for suppressing the use of information equipment is preferably a light source capable of controlling colored light and blinking in a wide range based on the light source driving condition data. Therefore, as an example of the light source 14b for suppressing the use of information equipment, there is a light source composed of red (Red), green (Green), and blue (Blue) LEDs (light emitting diodes). An example of the colored light emitted by the light source driving unit 14a is, for example, a primary color such as extreme red or blue, and such highly saturated colored light can be selected. Further, by controlling the control unit 13 to blink the light source 14b for suppressing the use of the information device, it is possible to effectively suppress the use of the mobile information device due to the user C of the mobile information device D feeling flickering. it can.

That is, the blinking cycle output by the control unit 13 to the light source driving unit 14a includes a blinking cycle (switching frequency) of between 5 and 70 Hz, preferably between 5 and 35 Hz, and most preferably between 15 and 20 Hz. .. Further, regarding the brightness of the light source 14b for suppressing the use of information equipment, it is preferable to control the brightness to ^{, for example, about 5000 cd / m 2 or more.} In particular, a light source having a brightness close to 5000 cd / m ² may cause the user C to feel dazzling even when the correlated color temperature is low (2000 K is an example). In this way, the user C becomes difficult to see the screen of the mobile information device D, abandons the continuous use of the mobile information device D, and is forced to leave the toilet booth A. As a result, the toilet booth A can be used by the next user who has been waiting for it as soon as possible.

Next, the entry detection signal obtained by amplifying the detection signal from the entry detection unit 11a via the amplification unit 11b is input to the control unit 13 (step S20).

Then, the control unit 13 determines the entry of the user C based on the entry detection signal (step S30). If the determination result in step S30 is No, the process returns to step S20, and the loop of steps S20 to S30 is repeated and waited until it is recognized that the user C has entered the room.

On the other hand, if the determination result in step S30 is Yes, the control unit 13 starts measuring the elapsed time of entering the room (step S40).

Next, the photoelectric conversion signal obtained by amplifying the light detection signal from the photoelectric conversion unit 12a via the amplification unit 12b is input to the control unit 13 (step S50).

Next, the control unit 13 determines whether or not the mobile information device D is used based on the photoelectric conversion signal (step S60).

If the determination result in step S60 is No, the control unit 13 stops counting the cumulative light emission time of the mobile information device D, returns to step S50 (step S80), and is used by the mobile information device D based on the photoelectric conversion signal. The loop of steps S50 to S60 is repeated and waited until it is recognized that the above is performed.

On the other hand, if the determination result in step S60 is Yes, the control unit 13 starts or restarts the measurement of the cumulative light emission time of the portable information device D (step S70).

Then, it is determined whether or not the cumulative light emission time of the portable information device D exceeds the predetermined time Td and the elapsed time of entering the room exceeds the predetermined time Tc (step S90). If the determination result in step S90 is No, the process returns to step S50, and the loop of steps S50 to S90 is repeated and waited until the usage time of the portable information device D exceeds the predetermined time Td.

On the other hand, if the determination result in step S90 is Yes, the control unit 13 outputs the light source drive condition data to the light source drive unit 14a (step S100).

Next, the light source 14b for suppressing the use of information equipment starts light emission based on the light source drive condition data (step S110). Next, the detection signal from the room entry detection unit 11a is amplified via the amplification unit 11b and input to the control unit 13 (step S120). Then, based on the detection signal, it is determined whether or not the user C is present in the room (step S130). If the determination result in step S130 is Yes, the process returns to step S120, and the loop of steps S120 to S130 is repeated and waited until it is recognized that the user C has left.

On the other hand, if the determination result in step S130 is No, the control unit 13 stops the light emission of the information device use suppression light source 14b, and ends the operation of the toilet booth long-stay suppression device 10 (step S140).

<Second Embodiment>
Next, the toilet booth long-stay restraint device 20 according to the second embodiment of the present invention will be described with reference to the drawings.

FIG. 4 shows the configuration of the control unit 23 of the toilet booth long-stay restraint device 20 according to the second embodiment of the present invention. In the toilet booth long-stay suppression device 20 according to the second embodiment of the present invention, the control unit 23 detects light from the entry determination unit 23a and the photoelectric conversion unit 12a that determine entry based on the detection signal from the entry detection unit 11a. The peak wavelength detection unit 23c that detects the peak wavelength based on the signal, the time measurement unit 23b that measures the elapsed time of entering the room and the device usage time of the mobile information device based on the determination result and the detection result, and the elapsed time of entering the room and It is different from the toilet booth long-stay suppression device 10 according to the first embodiment of the present invention in that it is provided with a light source drive signal generation unit 23d that can suppress the use of the mobile information device D based on the device usage time. The composition of the points is almost the same. Therefore, the components common to the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.

In the control unit 23, the determination unit 23a determines the entry of the user C based on the entry detection signal obtained by amplifying the biological information from the entry detection unit 11a, and the time measurement unit 23b determines the entry. Based on the result, the measurement of the elapsed time of entering the room (the elapsed time from the time of entering the room) is started.

Further, the peak wavelength detection unit 23c samples the photoelectric conversion signal obtained by photoelectrically converting the light detection signal obtained by amplifying the light of the light source emitted in the toilet booth A at predetermined time intervals. Then, based on the photoelectric conversion signal, the peak wavelength detection result indicating whether or not the peak wavelength can be detected is output to the time measurement unit 23b.

Then, the time measuring unit 23b measures the cumulative emission time of the peak wavelength based on the peak wavelength detection result.

Next, the light source drive signal generation unit 23d determines whether or not the use of the mobile information device D should be suppressed based on the elapsed time of entering the room from the time measurement unit 23b and the cumulative light emission time, and determines whether or not the use of the mobile information device D should be suppressed. The light source driving condition data (light emitting condition) for the purpose of suppressing the use of D is output to the light source driving unit 14a.

Based on the light source drive condition data, the light source drive unit 14a generates a light source drive waveform (control signal) for driving the light source 14b for suppressing the use of information equipment.

That is, if the mobile information device D is used for a predetermined time Td or longer even after the predetermined time Tc has passed since the user C entered the room, the user C can continue to use the mobile information device D. The light source 14b for suppressing the use of information equipment can emit light based on the light source drive waveform so as to be suppressed.

The peak wavelength detected by the peak wavelength detection unit 23c is preferably set to, for example, 430 to 440 [nm]. The reason is that a general smartphone adopts a blue LED (blue light), and its peak wavelength is designed to be around 430 to 440 [nm]. Therefore, it is preferable to provide a bandpass filter having a high transmittance in the vicinity of 430 to 440 [nm] in the light receiving region of the photoelectric conversion unit 12a to set a high sensitivity in the vicinity of 430 to 440 [nm].

<Third Embodiment>
Next, the toilet booth long-stay restraint device 30 according to the third embodiment of the present invention will be described with reference to the drawings. FIG. 5 shows the configuration of the toilet booth long-stay restraint device 30 according to the third embodiment of the present invention. FIG. 6 shows the configuration of the control unit 33 of the toilet booth long-stay restraint device 30 according to the third embodiment of the present invention. The toilet booth long-stay suppression device 30 according to the third embodiment includes a spectroscopic section 32a and a drive section 32b in place of the photoelectric conversion section and the amplification section 23c in the toilet booth long-stay suppression device 20 according to the second embodiment of the present invention. It is different from the toilet booth long-stay restraint device 20 according to the second embodiment of the present invention in that it is provided with a spectroscopic data analysis unit 33c instead of the peak wavelength light detection unit in the control unit 30, but in other respects. It is almost the same. The components common to the second embodiment are designated by the same reference numerals, and the description thereof will be omitted.

As shown in FIG. 5, the spectroscopic unit 32a in the toilet booth long-stay restraint device 30 according to the second embodiment of the present invention operates according to a control signal from the driving unit 32b under the control of the control unit 33. Then, the spectroscopic unit 32a transmits the time-divided spectroscopic data obtained by converting the light from the portable information device D used in the toilet booth A into the light intensity data for each wavelength. Then, the drive unit 32b converts the light intensity data for each wavelength into time-division spectroscopic data of the time-division method. Subsequently, the drive unit 32b transmits the time division spectroscopic data to the control unit 33 in time series.

Then, the spectroscopic data analysis unit 33c in the control unit 33 determines whether or not the emission peak caused by the portable information device D can be detected based on the time-division spectroscopic data, and determines the peak wavelength detection result in the time measurement unit 23b. Output to.

Specifically, the spectroscopic data analysis unit 33c sequentially reads the time-divided spectroscopic data from the driving unit 32b and stores the spectroscopic data representing the light intensity for each wavelength. The spectroscopic data analysis unit 33c analyzes the spectroscopic data and determines whether or not the peak wavelength can be detected. For example, the spectroscopic data analysis unit 33c compares the magnitude of the spectroscopic data for each wavelength and creates the intensity-ordered spectroscopic data arranged in the order of the magnitude of the spectroscopic data. Then, with respect to the intensity forward spectroscopic data, for example, based on the difference or ratio between the maximum value and the average value and the maximum value and the minimum value, it may be determined whether or not the wavelength at which the maximum value spectroscopic data is obtained is the peak wavelength. good. Further, the peak wavelength may be extracted based on the difference of the spectral data for each wavelength. Further, it may be determined whether or not the extracted peak is a peak by determining whether or not the extracted peak has a predetermined wavelength width.

Further, whether or not the light source drive control signal generation unit 23d should suppress the use of the portable information device D based on the detection results of the elapsed time of entering the room from the time measuring unit 23b and the accumulated light emission time (elapsed time). To judge.

Then, based on the determination result, the light source driving condition data (light emitting condition) for the purpose of suppressing the operation of the mobile information device D is output to the light source driving unit 14a. That is, when the light source drive control signal generation unit 23d determines that the use of the mobile information device D needs to be suppressed, the light source drive control signal generation unit 23d is based on the light source drive condition data so as to effectively suppress the use of the mobile information device D. The light source 14b for suppressing the use of information equipment can be made to emit light (lights up).

<Fourth Embodiment>
Next, the toilet booth long-stay restraint device 40 according to the fourth embodiment of the present invention will be described with reference to the drawings. The toilet booth long-stay deterrent device 40 according to the fourth embodiment of the present invention is different from the toilet booth long-stay deterrent device 30 according to the third embodiment in that it includes a spectral data storage unit 43c, but is omitted in other respects. It is the same. FIG. 7 shows the configuration of the control unit 43 of the toilet booth long-stay restraint device 40 according to the fourth embodiment of the present invention. The components common to the third embodiment are designated by the same reference numerals, and the description thereof will be omitted.

As shown in FIG. 7, the spectroscopic data storage unit 43c stores the spectroscopic data generated by the spectroscopic data analysis unit 33c under the control of the spectroscopic data analysis unit 33c, and outputs the stored spectroscopic data. Here, the background light and the spectral data at the time when the user C is not in the room are used as the background light in the toilet booth and the background spectral data in the toilet booth, respectively. The background light in the toilet booth is regarded as an extra light component when the user C wants to detect only the light caused by the display window of the portable information device D brought into the toilet booth.

Therefore, the spectroscopic data analysis unit 33c performs an operation to remove the background spectroscopic data in the toilet booth from the spectroscopic data when the user C brings the portable information device D into the toilet booth and uses it. By this calculation, the spectroscopic data analysis unit 33c can analyze spectroscopic data that is not affected by the background spectroscopy in the toilet booth.

Then, the spectroscopic data analysis unit 33c can efficiently extract the spectroscopic data caused by the portable information device D. Further, when the spectroscopic data analysis unit 33c determines that the user C has used the portable information device D, the peak wavelength at which each spectroscopic data can be detected, the acquisition date and time, the elapsed time of entering the room, and the cumulative emission time (elapsed time) ) Is associated and stored.

The spectroscopic data analysis unit 33c may store the spectroscopic data, the detected peak wavelength, and the acquisition date and time as user-specific spectroscopic data in the spectroscopic data storage unit 43c. Then, the spectroscopic data analysis unit 33c may predict and analyze the frequency of the detected peak wavelength by statistically processing the spectroscopic data for each user. For example, the light source drive control data of the information device use suppression light source 14b may be adjusted according to the detected peak wavelength by finding the correlation between the individual spectral data and the usage time of the portable information device D. Further, as an example of the spectroscopic data storage unit 43c in the toilet booth long-stay suppression device according to the fourth embodiment of the present invention, a non-volatile buffer memory can be mentioned.

Although the embodiments of the present invention have been described above, each embodiment shows a preferable example, and other structures or configurations having similar effects and characteristics are within the scope of the present invention. It goes without saying that the present invention is not limited to the above-described embodiment, and various changes can be made without departing from the gist of the present invention.

As described above, in the toilet booth long-stay deterrent device of the present invention, whether or not the light emitted from the display (display surface) of the mobile information device D has a peak wavelength in order to detect the use of the mobile information device D. It was shown that a peak wavelength detection unit for determining whether or not to provide is provided.

However, in order to detect the use of the portable information device, another detection method may be adopted. For example, in order to improve the moving image characteristics of the screen of a smartphone, for example, there is a device that controls the blinking of the backlight at a frequency of 120 Hz or higher. Therefore, instead of the peak wavelength detection unit 23c, a blinking cycle detection unit (not shown) for measuring or detecting the blinking of the display (display surface) of the portable information device D or the period of brightness may be provided. good. For example, if the display (display surface) is a liquid crystal display panel, the frequency detected by the blinking cycle detection unit is the frequency f _{F obtained} by adding an integral multiple of 60 Hz to 120 Hz (that is, the frequency f _F or higher = 120 + 60 n (n = 0,). 1, 2, ... Integer) may be set. _{If n = 2 at the frequency f F} , the light of the backlight that controls the lighting of the backlight of the liquid crystal display panel at a frequency of 240 kHz is detected. The blinking frequency of the backlight of the display (display surface) is not limited to such an example, and may be an integral multiple of the writing frequency of the liquid crystal display panel.

On the other hand, even when the display (display surface) is a light emitting display such as an organic EL, the use of the portable information device D can be detected by the blinking cycle detection unit similar to the above.

Further, in the toilet booth long-stay deterrence device according to each embodiment of the present invention, as an example of the light source 14b for deterring the use of information equipment, a light source composed of red (Red), green (Green), and blue (Blue) LEDs. However, a light source that emits other colored light may be adopted. For example, a light source such as a combination of lamps that emit white light to which corresponding color filters are added so as to light red, green, and blue may be adopted. In addition, red, green, and blue organic ELs may be used.

Further, the color of the light source is not limited to the three primary colors of red (Red), green (Green) and blue (Blue), and may be four primary colors including yellow (Yellow), and one or two colors, Alternatively, the colors of the light sources having five or more primary colors may be adopted for the information device use suppression light source 14b, and the number of colors of the light source adopted for the information device use suppression light source 14b is not particularly limited.

Next, in the toilet booth long-stay suppression device according to each embodiment of the present invention, in order to control the control unit to blink the light source 14b for suppressing the use of information equipment, the light source is turned on / as the light source drive condition data. Although it has been shown that a drive control signal that turns off is output to the light source drive unit 14a, a light emitting element that cannot perform flicker control (blinking control) due to a long response time may be used.
