Description

The present invention relates to a determination device, a determination method, a program, and a recording medium for determining the necessity of collecting garbage from a garbage collection point.

For garbage collection, usually, a garbage collection point for collecting garbage is determined for each collection vehicle of the collection company, and garbage is collected by visiting all the garbage collection points on the determined collection date. However, from the previous collection date to the next collection date, not all garbage collection points have accumulated a sufficient amount of garbage that needs to be collected. For this reason, garbage collection points where collection is less necessary are also toured, which wastes time and fuel for recovery vehicles.

Therefore, in recent years, a method has been proposed in which all the trash cans placed in the trash can are used as IoT trash cans. The IoT trash can is a trash can provided with a sensor for measuring the amount of discarded trash and a transmission / reception function for transmitting the sensing information thereof. Then, the IoT trash can transmits sensing data indicating the amount of trash to the server, and the server manages the amount of trash for each IoT trash can in real time (for example, Patent Documents 1, 2, and 3). However, according to this method, it is necessary to replace all the trash cans arranged in the trash can with the IoT trash can, and the introduction cost becomes extremely high. Further, depending on the garbage collection point, the area is only defined, and the trash can may not always be installed, so that the IoT trash can cannot be used.

The CPU 101 is a processor that controls the entire determination device 10, and is not limited to the CPU, and may be another processor. In the determination device 10, for example, the program of the present invention and other programs are executed by the CPU 101, and various information is read and written.

The determination device 10 can be connected to the communication network by, for example, the communication device 106 connected to the bus 103, and can also be connected to an external device via the communication network. The external device is not particularly limited, and is, for example, a terminal, a notification device, a database, a PC (personal computer), or the like, as will be described later. The terminal is, for example, a tablet, a smartphone, a mobile phone, or the like, and the notification device is, for example, a sensor, an IoT button, or the like described later. The connection method between the determination device 10 and the external device is not particularly limited, and may be, for example, a wired connection or a wireless connection. The wired connection may be, for example, a cord connection or a cable connection for using a communication network. The wireless connection may be, for example, a connection using a communication network or a connection using wireless communication. The communication network is not particularly limited, and for example, a known communication network can be used, and is the same as described above.

The memory 102 includes, for example, a main memory, and the main memory is also referred to as a main storage device. When the CPU 101 performs processing, for example, the memory 102 reads various operation programs 108 such as the program of the present invention stored in the auxiliary storage device described later, and the CPU 101 receives data from the memory 102. , Program 108 is executed. The main memory is, for example, a RAM (random access memory). The memory 102 further includes, for example, a ROM (read-only memory).

The notification device 30 may be any device that can output to the determination device 10 via the communication network 20 that the disposer has used the garbage collection point 31, that is, that the garbage has been disposed of at the garbage collection point 31. Specific examples of the notification device 30 include a sensor, an IOT button, and the like. The sensor is not particularly limited as long as it is a sensor capable of detecting that the waste has used the garbage collection point 31, and as a specific example, it can detect the opening / closing of the trash can installed in the garbage collection point 31. Open / close sensor can be mentioned. In this case, the notification device 30 (open / close sensor) is installed on the lid of the trash can installed in the garbage collection point 31, and for example, when the lid is detected to be opened, the opening / closing of the trash can is used as the log information.

When the notification device 30 is the IOT button, the notification device 30 includes, for example, a button, and when the button is pressed, the information that "the button is pressed" is acquired as the log information, and the notification device 30 is used. It is output to the determination device 10 together with the identification information of. Therefore, the log information can be said to be, for example, information recording the use of the garbage collection point 31. The log information may include, for example, information on the date and time when the log information was acquired. For example, the notification device 30 may output the notification information to the determination device 10 every time the log information is acquired, or may output the notification information to the determination device 10 at predetermined intervals. In the latter case, the notification device 30 has, for example, a storage unit, stores the acquired log information as the log information in association with the acquisition date and time of the log information, and stores the acquired log information at intervals of the predetermined intervals. It is preferable to output the log information and the acquisition date and time together.

Each part of the determination device 10 will be described in more detail.

The storage unit 11 stores the garbage collection point information for each of the plurality of garbage collection points 31 (n and n are arbitrary positive integers). The garbage collection point information includes identification information of the garbage collection point 31, identification information of the notification device 30 for notifying the use of the garbage collection point 31, notification information acquired from the notification device 30, and garbage for the garbage collection point 31. The collection history information is linked. The storage unit 11 has, for example, a garbage collection point information folder for each garbage collection point 31, and the identification information of the garbage collection point 31 and a notification device installed in the garbage collection point 31 in advance in the folder. The identification information of 30 is stored. Then, the information from the notification device 30 and the information from the terminal 40 of the garbage collector are collected from the garbage collection point, for example, based on the identification information of the garbage collection point 31 or the identification information of the notification device 30 included in the information. It can be accumulated in each folder of 31.

The identification information of the garbage collection point 31 is, for example, information that can identify the garbage collection point 31, and specific examples thereof include an ID, an address, and latitude / longitude. The identification information of the notification device 30 is, for example, information that can identify the notification device 30, and specific examples thereof include an ID, identification information of the installed garbage collection point 31 and the like.

The notification information is associated with, for example, the identification information of the notification device 30 and the log information of the notification device 30. When the garbage collection point 31 is used by the discardor and the button of the notification device 30 is pressed, for example, the notification information is transmitted from the notification device 30 to the determination device 10 via the communication network 20 to be transmitted to the determination device 10. Acquires the notification information by the information acquisition unit 12, and stores the notification information in the storage unit 11. Since the notification information from the notification device 30 includes, for example, the identification information of the notification device 30, it can be classified and stored in a folder for each garbage collection point 31 of the storage unit 11 based on the identification information. When the log information included in the notification information includes the acquisition date and time of the log information, the determination device 10 may store the acquisition date and time in association with the notification information, and the log information is the acquisition date and time. If is not included, for example, the date and time when the determination device 10 acquired the notification information may be estimated as the acquisition date and time of the log information, and the date and time may be stored in association with the notification information.

The garbage collection history information for the garbage collection point 31 is, for example, the garbage collection date and time. For example, the collection company inputs the garbage collection history information such as the garbage collection date and time into the terminal 40. Then, the garbage collection history information is transmitted from the terminal 40 to the determination device 10 via the communication line network 20, the determination device 10 acquires the garbage collection history information by the information acquisition unit 12, and the storage unit 11 obtains the garbage collection history information. Store garbage collection history information. Further, the garbage collection history information may further include, for example, garbage amount information at the time of collection in association with the garbage collection date and time. The garbage amount information is, for example, information on whether or not the amount of garbage collected by the garbage collector is sufficient to be collected at the time of collection, and may be two-choice information of "sufficient or insufficient" or the amount. Information may be divided into multiple stages. For example, when the collection company collects the garbage, the garbage amount information is input to the terminal 40 after confirming the garbage accumulated in the garbage collection point 31, and is transmitted to the determination device 10 and stored in the same manner as described above. Will be done. The dust amount information may be transmitted to the determination device 10 in association with the identification of the dust collection point 31 or the notification device 30, for example.

As described above, the information acquisition unit 12 acquires the notification information from the notification device 30 of the garbage collection point 31, and the acquired information is stored in, for example, the storage unit 11. The determination device 10 may acquire information from the notification device 30 and the terminal 40 via, for example, the information acquisition unit 12, but is not limited thereto. Information from the notification device 30 and the terminal 40 is stored in a database outside the determination device 10, for example, the determination device 10 acquires information from the database via the communication network, and various types are stored in the storage unit 11. Information may be stored.

The determination unit 14 extracts the number of notifications from the notification device 30 after the final garbage collection date and time based on the garbage collection history information and the notification information for each garbage collection point 31, and the number of notifications is determined by the number of notifications. If it exceeds the threshold value, it is determined that collection is necessary, and if the number of notifications is equal to or less than the threshold value, it is determined that collection is unnecessary. The method of setting the threshold value is not particularly limited. An example of the threshold setting method will be described later.

The extracted number of notifications may be further stored, for example, in the storage unit 11 as the garbage collection history information in association with the collection date and time.

The output unit 15 outputs the determination result. For example, the output unit 15 may output the determination result to the external device (for example, the user's terminal 40) as described above, or may output the determination result to the display 105 in the determination device 10 for display. Further, the determination result may be further stored in the storage unit 11 as, for example, garbage collection site information.

Next, the determination method of the present embodiment will be described with reference to the flowchart of FIG. The determination method of the present embodiment includes a determination step and an output step, and may optionally include an information acquisition step. The determination method of the present embodiment can be carried out using, for example, the determination device 10 shown in FIGS. 1 and 2. The determination method of the present embodiment is not limited to the use of the determination device 10.

First, the storage unit 11 of the determination device 10 stores the garbage collection point information for each garbage collection point 31. As described above, the storage unit 11 stores the identification information of the garbage collection point 31 and the identification information of the installed notification device 30 in advance in association with each other. Then, in the information acquisition step, the notification information from the notification device 30 is acquired (S101), the garbage collection history information from the user's terminal 40 is acquired (S102), and various information thereof are stored in the storage unit 11. In, each garbage collection point 31 is stored (S103). The information acquisition step can be executed, for example, by the information acquisition unit 12 of the determination device 10.

As a result, for example, as shown in FIG. 4, the garbage collection point information is accumulated for each garbage collection point 31. In the table of FIG. 4A, the identification information of the garbage collection point 31 and the identification information of the notification device 30 installed there are associated with each garbage collection point 31, and FIG. 4B is shown. The table of FIG. 4 (C) is associated with the notification information (notification date and time) from the notification device 30 and the identification information of the garbage collection point 31 in which the notification device 30 is installed. As the history information, the garbage collection date and time, the garbage amount information, and the identification information of the garbage collection point 31 are associated with each other. In FIG. 4C, the dust amount information is described as "TRUE" when the amount is sufficient, and "FALSE" when the amount is not sufficient (insufficient). Further, the number of notifications extracted in (S104) described later is further linked to the table of FIG. 4 (C).

Then, for each garbage collection point 31, the number of notifications from the notification device 30 after the final garbage collection date and time is extracted based on the garbage collection history information and the notification information (S104), and the number of notifications is set. It is determined whether or not the threshold value is exceeded (S105), if the threshold value is exceeded (YES), it is determined that recovery is necessary (S106), and if it is below the threshold value (NO), it is determined that recovery is unnecessary (S107). The steps (S104) to (S107) can be executed by, for example, the determination unit 14 of the determination device 10.

For example, when ID = B is selected as the identification information of the garbage collection point 31, the final garbage collection date and time “2019/1/17 10:11” is selected from the garbage collection history information in FIG. 4C, and further. From the notification information of FIG. 4B, the number of notification information after 10:11 on January 17, 2019 is extracted as "3 times". Whether or not collection is necessary can be determined by whether or not these three times exceed an arbitrary threshold value of the garbage collection point B with ID = B.

Then, the obtained determination result is output (S108), and the process ends (END). The output step can be executed, for example, by the output unit 15 of the determination device 10.

According to the present embodiment, the necessity of collecting garbage is determined for each of the plurality of garbage collection points, and the determination result is output. Therefore, the user who is a collection company can use, for example, the terminal 40 to determine the determination result. It is possible to select and collect only the garbage collection points that need to be collected from the garbage collection points to be collected. Therefore, the time required for the user's collection can be shortened, and the fuel of the garbage collection vehicle used for the collection can also be saved. Then, based on the determination result, the collection company that has collected the garbage can further input the amount of garbage in the garbage collection point into the terminal 40 and feed back the result to the determination device 40. Then, at the time of the next collection, the necessity of garbage collection is determined by using the feedback information, so that the determination with excellent reliability becomes possible.

[Embodiment 2]
In the present invention, the setting of the threshold value is not particularly limited in determining the necessity of collecting dust. The method of setting the threshold value will be illustrated below based on the garbage collection point information illustrated in FIG. The following is an example and does not limit the present invention. Further, the present embodiment is the same as the determination device and determination method of the first embodiment unless otherwise specified.

(1) Calculation of average value The determination device of the present embodiment further includes, for example, a threshold value setting unit, and the threshold value setting unit is based on the collection history information and the notification information for each garbage collection point. For the garbage collection date for which the amount of garbage is insufficient, the number of notifications after the previous collection date and time is extracted, and the average value thereof is set as the threshold value. Further, the determination method of the present embodiment further includes, for example, a threshold value setting step, and in the threshold value setting step, the amount of garbage is not large based on the collection history information and the notification information for each garbage collection point. For the sufficient garbage collection date, the number of notifications after the previous collection date and time is extracted, and the average value thereof is set as the threshold value.

In this embodiment, for example, as shown in FIG. 4, when the garbage collection history information includes garbage amount information, the threshold value can be set from the average value of the number of notifications by using this information. At the garbage collection point, the amount of garbage discarded differs depending on the environment. For example, it is assumed that the amount of garbage discarded at one time also differs. Therefore, by using information on whether or not a sufficient amount of dust has been accumulated in the actual collection, it becomes possible to more accurately determine whether or not the dust needs to be collected.

In the present embodiment, for example, first, as shown in FIG. 5A, at the collection date and time when it is determined that the garbage amount information is insufficient (FALSE) for each garbage collection point based on the garbage collection history information. Extract the number of notifications. At the garbage collection point (ID = A), the number of notifications when it is determined to be FALSE is 5, 5, or 4, so the threshold value is the average value of 4.666666667. Further, since the garbage collection point (ID = B) receives one, one, and two notifications when it is determined to be FALSE, the threshold value is the average value of 1.333333333. Further, in the garbage collection point (ID = C), the number of notifications when it is determined to be FALSE is once or twice, so the threshold value is an average value of 1.5.

On the other hand, when the final garbage collection date and time is selected from the garbage collection history information of FIG. 4 (C) and the number of notification information after the final garbage collection date and time is extracted from the notification information of FIG. 4 (B). , ID = A, B, C, the information of the garbage collection point is as shown in FIG. 5 (B), respectively. Then, by comparing the number of notifications and the threshold value for each garbage collection point, if the number of notifications is larger than the threshold value, garbage collection is required (TRUE), and if the number of notifications is less than the threshold value, garbage collection is unnecessary (). It can be determined as FALSE). According to such a determination, for example, as described above, it is possible to determine a more suitable collection necessity for each garbage collection point.

(2) Calculation of average value for a limited period The amount of garbage discarded at each garbage collection point is considered to differ depending on the environment of the area where the garbage collection point is located. , It is understood that it will change gradually due to the move of residents. For this reason, by using information that is closer to the present than older past information in setting the threshold value, it is possible to make a more reliable judgment due to changes in the environment in which the garbage collection point is installed. Become. Therefore, in the present embodiment, the collection history information and the notification information from a predetermined time to the latest time are used in the threshold value setting unit and the threshold value setting step.

The predetermined time is not particularly limited, and for example, information from several months ago, several weeks ago, or several days ago to the latest time is preferable, and specifically, for example, information from 6 months ago and 3 months ago. Information, information from one month ago, etc. are preferable.

In the present embodiment (2), for example, assuming that the current time is January 22, 2019, as shown in FIG. 6 (A), the information for 14 days from the current time, that is, January 8, 2019. Based on the following information, the number of notifications at the collection date and time when it is determined that the garbage amount information is insufficient (FALSE) is extracted for each garbage collection point. At the garbage collection point (ID = A), the number of notifications when it is determined to be FALSE is 5 times or 4 times, so the threshold value is an average value of 4.5. Further, in the garbage collection point (ID = B), the number of notifications when it is determined to be FALSE is once or twice, so the threshold value is an average value of 1.5. Further, since the garbage collection point (ID = C) receives only two notifications when it is determined to be FALSE, the threshold value is 2.

Then, as shown in FIG. 6B, by comparing the number of notifications with the threshold value for each garbage collection point, if the number of notifications is larger than the threshold value, garbage collection is required (TRUE), and the number of notifications is the threshold value. If the following, it can be determined that garbage collection is unnecessary (FALSE). According to such a determination, for example, as described above, it is possible to determine a more suitable collection necessity for each garbage collection site in consideration of changes in the local environment.

(3) Calculation of Weighted Average For the same reason as in (2) above, in the present embodiment, in the threshold value setting unit and the threshold value setting step, the weighted average value is set to the threshold value by weighting the number of notifications. It is a form. Since the information close to the present time is considered to be in line with the current environment, the weight is set larger as it is closer to the latest time and smaller as it is farther from the latest time.

The weight can be set, for example, as shown in FIG. 7 (A). FIG. 7A is a table in which the garbage collection dates and times are listed in order from the oldest. First, each garbage collection date and time is converted into a numerical value indicating the length of time (a column of numerical values in the table), and a difference indicating the degree of progress is calculated based on the oldest collection date and time (the elapsed number in the table). Column). Next, the change width is calculated so that the value of the oldest collection date and time is zero and the value of the latest collection date and time is 10 (column of the change width in the table). Further, the range of change from zero to 10 is modified from the range of change from -5 to +5 (column of modification in the table). Then, each weight is calculated from the ^{equation [1 / (1 + e −x} )] based on the standard sigmoid function using the modified numerical value of the change width. Then, after weighting each notification number (column of the number of notifications in the table) in which the amount of garbage is insufficient, a weighted average is obtained for each garbage collection point, and this is used as a threshold value.

Then, as shown in FIG. 7B, by comparing the number of notifications and the threshold value for each garbage collection point, if the number of notifications is larger than the threshold value, garbage collection is required (TRUE), and the number of notifications is the threshold value. If the following, it can be determined that garbage collection is unnecessary (FALSE). According to such a determination, for example, as described above, it is possible to determine a more suitable collection necessity for each garbage collection site in consideration of recent changes in the local environment.
