Description

[Technical field]

[0001] The present invention relates to a garbage collection status management system that is operated by connecting a host terminal that can be operated by workers who stop by a garbage collection site and a management server that manages information about the garbage collection site via a public communication line, and to a garbage collection truck equipped with said garbage collection status management system. [Background technology]

[0002] Generally, burnable waste and non-burnable waste are accumulated at waste collection points, collected by waste collection trucks (packer trucks), and transported to incineration facilities, etc. In order to manage whether or not waste at such waste collection points has been collected by a waste collection truck, a waste collection status management system has been proposed (see, for example, Patent Document 1).

[0003] The waste collection status management system described in Patent Document 1 includes a mobile terminal and a management server. In this waste collection status management system, the management server selects potential waste collection points based on location information acquired by the mobile terminal, and transmits the potential waste collection points to the mobile terminal. From the potential waste collection points transmitted by the management server, a worker can operate the mobile terminal to select a waste collection point that has been worked on (where waste has been collected), thereby generating waste collection status data that associates the selected waste collection point with the waste collection status. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 7473140 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the waste collection status management system in Patent Document 1 requires workers to select a waste collection site that has already been worked on each time, which is time-consuming and burdensome for the workers. In addition, there is a problem that if a worker forgets to operate the mobile terminal, the information is not updated.

[0006] The present invention has been made in consideration of the above problems, and has an object to provide a waste collection status management system that enables workers to easily obtain waste collection status data without having to spend time on the work, and to provide a waste collection truck equipped with the waste collection status management system. [Means for solving the problem]

[0007] The characteristic configuration of the waste collection status management system according to the present invention for solving the above problems is as follows: A waste collection status management system that is operated by connecting a host terminal that can be operated by a worker who stops by a waste collection site and a management server that manages information about the waste collection site via a public communication line, a wearable terminal held by the worker and connected to the host terminal; The wearable terminal includes: A worker position information acquisition means for acquiring the worker position information; a wearable terminal transmitting means for transmitting the worker position information acquired by the worker position information acquiring means to the host terminal; Equipped with The host terminal includes: A host terminal receiving means for receiving the worker position information from the wearable terminal transmitting means; a host terminal transmitting means for transmitting the worker position information to the management server; Equipped with The management server includes: A management server storage means for storing a list of waste collection points that associates preregistered waste collection points with location information of the waste collection points; A determination means for determining whether or not garbage has been collected from a garbage collection point registered in the garbage collection point list; a data generating means for generating waste collection status data that associates a waste collection status with a waste collection site determined by the determining means to have collected waste; Equipped with The determination means determines that garbage at a garbage collection point registered in the garbage collection point list has been collected if the garbage collection point is present within a specified range based on the position identified from the worker position information.

[0008] According to the waste collection status management system of this configuration, the location information of the worker (worker location information) acquired by the wearable terminal is transmitted to the host terminal, and is then transmitted from the host terminal to the management server via a public communication line. If a waste collection point registered in the waste collection point list is present within a predetermined range based on the position identified from the worker location information, the management server determines that the waste at the waste collection point has been collected. Therefore, since the waste at the waste collection point is determined to have been collected when the worker approaches the waste collection point to collect the waste, the worker does not need to select the waste collection point where the worker has already worked each time, which saves the worker time. Then, the waste collection status data is generated in which the determination means associates the waste collection status with the waste collection point where the waste has been collected.

[0009] In the waste collection status management system according to the present invention, the wearable terminal includes a wearable terminal storage means for storing the worker position information acquired by the worker position information acquisition means while the wearable terminal is not connected to the host terminal, It is preferable that the wearable terminal transmission means is configured to transmit the worker position information stored in the wearable terminal storage means to the host terminal collectively when the wearable terminal and the host terminal are connected.

[0010] For example, if the host terminal is installed in a garbage collection truck, the wearable terminal and the host terminal are connected while the worker is on the garbage collection truck, but when the worker leaves the garbage collection truck to collect garbage and goes to a garbage collection site where radio waves cannot reach, the connection between the wearable terminal and the host terminal is cut off. According to the garbage collection status management system of this configuration, the wearable terminal includes a wearable terminal storage means that stores the worker position information acquired by the worker position information acquisition means while the wearable terminal is not connected to the host terminal, so that the worker position information acquired by the worker position information acquisition means while the wearable terminal and the host terminal are not connected is not lost. In addition, the wearable terminal transmission means is configured to transmit the worker position information stored in the wearable terminal storage means to the host terminal together when the wearable terminal and the host terminal are connected, so that all the worker position information acquired by the worker position information acquisition means can be transmitted to the host terminal.

[0011] In the waste collection status management system according to the present invention, The host terminal includes an input means for inputting information about a garbage collection site, The host terminal transmission means is preferably configured to transmit information about the waste collection point input by the input means to the management server.

[0012] According to the waste collection status management system of this configuration, since it is equipped with an input means, for example, when a worker discovers a problem at a waste collection site while collecting waste, he or she can input information regarding the problem at the waste collection site and send the information to the management server.

[0013] In the waste collection status management system according to the present invention, The predetermined range is preferably set in a plurality of stages.

[0014] According to the waste collection status management system of this configuration, the specified range is set in multiple stages, so that among the waste collection points where it is determined that waste has been collected, it becomes clear which waste collection points have definitely had waste collected and which waste collection points may not have had waste collected, making it possible to obtain more accurate waste collection status data.

[0015] In the waste collection status management system according to the present invention, The wearable terminal preferably includes a detection means for detecting a collection action of the worker.

[0016] According to the waste collection status management system of this configuration, the wearable device is equipped with a detection means, so that it can detect the collection action of the worker and accurately grasp whether the worker actually collected the waste, thereby obtaining more accurate waste collection status data.

[0017] In the waste collection status management system according to the present invention, The wearable device is preferably a smart watch.

[0018] According to the waste collection status management system of this configuration, the wearable device is a smart watch, so the worker's hands are free to use it and it does not interfere with the worker's actions to collect waste. In addition, the wearable device is unlikely to be dropped while the worker is collecting waste, so damage to the wearable device can be prevented.

[0019] The garbage collection vehicle according to the present invention for solving the above problems has the following features: The vehicle is equipped with at least a part of any one of the above waste collection status management systems.

[0020] According to the garbage collection vehicle of this configuration, since at least a part of the garbage collection status management system is installed, it is possible to easily manage whether or not garbage at the garbage collection site has been collected by the garbage collection vehicle.

[Diagram 3] FIG. 3 is a conceptual diagram of the selection of a waste collection site in the waste collection status management system of this embodiment. [Figure 4] FIG. 4 is a flowchart showing the procedure of waste collection status management carried out in the waste collection status management system of this embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] The waste collection status management system of the present invention will be described below. However, the present invention is not intended to be limited to the embodiments described below or the configurations shown in the drawings. In this specification, the term "waste collection point" literally refers to the waste collection point itself and also refers to information (data) related to the waste collection point.

[0023] <Overall composition> FIG. 1 is an overall configuration diagram of a waste collection status management system 100 according to an embodiment of the present invention. At least a part of the waste collection status management system 100 can be mounted on a waste collection truck 200, and is used to manage whether or not waste at a waste collection point has been collected by the waste collection truck 200. On a waste collection day, the waste collection truck 200 moves from one waste collection point to another to collect waste, and finally transports the waste to an incineration facility or the like. A worker riding on the waste collection truck 200 performs collection work by picking up waste at each waste collection point and loading it into the waste collection truck 200. As shown in FIG. 1, the waste collection status management system 100 includes a wearable terminal 1 held by a worker, a host terminal 2 that can be operated by a worker who stops by a waste collection point, and a management server 3 that manages information about the waste collection point. In this embodiment, the waste collection truck 200 is equipped with the host terminal 2. The wearable terminal 1 is connected to the host terminal 2, and the host terminal 2 and the management server 3 are connected and operated via a public communication line (such as the Internet) NW.

[0024] 2 is a functional block diagram of the waste collection status management system 100 of this embodiment. The functions of the wearable terminal 1, the host terminal 2, and the management server 3 will be described with reference to FIGS.

[0025] <Wearable devices> The wearable terminal 1 is held by a worker (lend by a waste collection company) and connected to the host terminal 2. The wearable terminal 1 is a terminal that the worker can wear on a part of the body such as the arm or head, and examples of such terminals include wristband-type or watch-type terminals worn on the wrist, clip-type terminals attached to clothing or belts, eyeglass-type terminals worn on the face, and ring-type terminals worn on the finger. A small terminal such as a smartphone can also be used as the wearable terminal 1 by holding it on the arm using an attachment such as an armband. In this embodiment, it is preferable to use a wristband-type or watch-type terminal worn on the wrist as the wearable terminal 1, and a smart watch can be particularly preferably used. Since the wearable terminal 1 is a smart watch, both hands of the worker are not occupied, so it does not interfere with the operation of collecting waste. In addition, the wearable terminal 1 is unlikely to be dropped by the worker when collecting waste, so that damage to the wearable terminal 1 can be prevented.

[0026] The wearable device 1 includes a communication unit 10, a processing unit 20, and a storage unit 30.

[0027] [Communications Department] The communication unit 10 connects the wearable terminal 1 to the host terminal 2 by wired or wireless communication between the wearable terminal 1 and the host terminal 2. In this embodiment, the communication unit 10 is preferably configured with a short-range wireless communication module. Examples of communication standards for short-range wireless modules include Bluetooth (registered trademark), Wi-Fi (registered trademark), ZigBee (registered trademark), and UWB. By configuring the communication unit 10 with a short-range wireless communication module, the wearable terminal 1 and the host terminal 2 can be easily connected while suppressing power consumption. In addition, since a public line such as a telephone line is not used, no communication fee is charged for communication between the wearable terminal 1 and the host terminal 2. As shown in FIG. 2, the communication unit 10 has a wearable terminal transmission means 11.

[0028] The wearable terminal transmission means 11 transmits information acquired by the wearable terminal 1 (worker position information 31 acquired by worker position information acquisition means 21 described later, and behavior information 32 acquired by detection means 22 described later) to the host terminal 2. When the wearable terminal 1 is connected to the host terminal 2, the wearable terminal transmission means 11 transmits the information acquired by the wearable terminal 1 to the host terminal 2.

[0029] The wearable terminal transmission means 11 is preferably configured to transmit information (worker position information 31 and behavior information 32) acquired by the wearable terminal 1 stored in the storage unit 30 to the host terminal 2 together when the wearable terminal 1 and the host terminal 2 are connected. For example, when the host terminal 2 is installed in a garbage collection truck 200, the wearable terminal 1 and the host terminal 2 are connected while the worker is aboard the garbage collection truck 200, but when the worker leaves the garbage collection truck 200 to collect garbage and goes to a garbage collection site where radio waves cannot reach, the connection between the wearable terminal 1 and the host terminal 2 is cut off. Even in such a situation, when the wearable terminal 1 and the host terminal 2 are connected, the wearable terminal transmission means 11 transmits the worker position information 31 and behavior information 32 stored in the storage unit 30 together to the host terminal 2, so that the worker position information 31 acquired by the worker position information acquisition means 21 and the behavior information 32 acquired by the detection means 22 can all be transmitted to the host terminal 2.

[0030] [Processing section] As shown in FIG. 2, the processing unit 20 includes a worker position information acquiring means 21 and a detecting means 22.

[0031] [Worker location information acquisition means] The worker position information acquisition means 21 acquires position information indicating the current position of the wearable device 1. That is, since the wearable device 1 is held by a worker, the position information indicating the current position of the wearable device 1 acquired by the worker position information acquisition means 21 corresponds to the position information indicating the current position of the worker (worker position information 31). The worker position information acquisition means 21 acquires the worker position information 31 based on a positioning signal from GPS, which is one of the GNSS (Global Navigation Satellite System). The worker position information acquisition means 21 may also use Michibiki as the QZSS (Quasi-Zenith Satellite System). The worker position information 31 acquired by the worker position information acquisition means 21 includes each data related to the position such as latitude, longitude, and altitude. The worker position information 31 may also include information (date and time) related to the time when the position information is acquired. In this embodiment, the worker position information acquisition means 21 is configured to automatically acquire the position information of the wearable device 1 at regular intervals (for example, every 1 to 30 seconds). By automatically acquiring the position information at regular intervals, it becomes possible to identify the garbage collection points where the worker has completed the work without the worker having to take the time to do so. Alternatively, the means 21 may be configured to automatically acquire the position information of the wearable device 1 by detecting the movement of the worker (for example, by detecting vertical vibrations when walking). By automatically acquiring the position information of the wearable device 1 by detecting the movement of the worker, data is not acquired when the worker is not moving, so that the required worker position information 31 can be obtained while suppressing the overall amount of data.

[0032] The worker position information acquisition means 21 may acquire the worker's position information only while the wearable terminal 1 and the host terminal 2 are not connected. For example, if the host terminal 2 is installed in the garbage truck 200, the wearable terminal 1 and the host terminal 2 are connected while the worker is aboard the garbage truck 200, so the worker position information 31 is not acquired, and the worker position information 31 is acquired only while the worker leaves the garbage truck 200 to go to a garbage collection site where radio waves cannot reach in order to collect garbage. In this way, by acquiring the worker position information 31 by the worker position information acquisition means 21 only while the wearable terminal 1 and the host terminal 2 are not connected, unnecessary data is not acquired, so that the power consumption of the wearable terminal 1 can be reduced.

[0033] [Detection Method] The detection means 22 detects the collection action (behavior) of the worker. The detection means 22 is not particularly limited as long as it can detect information (behavior information 32) indicating the movement of the worker, and may be, for example, a gyro sensor. The gyro sensor detects angular velocity data by measuring angular velocity in each of three mutually orthogonal axial directions. Therefore, when the wearable terminal 1 is equipped with a gyro sensor, the wearable terminal 1 can be held on the wrist of the worker to detect information (behavior information 32) indicating the movement of the worker, such as the collection action when the worker lifts up and collects the garbage and the walking action of the worker. In addition, the detection means 22 may be, for example, a camera that captures the movement of the worker. In the case where the wearable terminal 1 is a smart glass, the garbage picked up by the worker is captured in an image captured by the camera of the smart glass, so that the collection action when the worker lifts up and collects the garbage can be detected. By providing the detection means 22, it becomes possible to accurately grasp whether the worker actually collected the garbage.

[0034] [Storage section] The memory unit 30 is a storage built into the wearable terminal 1, and functions as a wearable terminal storage means for storing and saving various data. In this embodiment, the memory unit 30 stores information (worker position information 31 and behavior information 32) acquired by the wearable terminal 1 while the wearable terminal 1 and the host terminal 2 are not connected. With this configuration, the worker position information 31 acquired by the worker position information acquisition means 21 and the behavior information 32 acquired by the detection means 22 while the wearable terminal 1 and the host terminal 2 are not connected are not lost. The worker position information 31 and the behavior information 32 are read from the memory unit 30 at an appropriate timing.

[0035] <Host terminal> The host terminal 2 can be operated by a worker who stops by the garbage collection site, and is connected to the wearable terminal 1 and the management server 3. Examples of the host terminal 2 include communication terminals such as desktop personal computers, notebook computers, and tablet computers. In this embodiment, the host terminal 2 is preferably installed in the garbage collection truck 200, and from this point of view, a notebook computer or a tablet computer is preferable. Installing the host terminal 2 in the garbage collection truck 200 can prevent the host terminal 2 from being dropped or damaged by getting wet in the rain.

[0036] The host terminal 2 includes a communication unit 40, a processing unit 50, and a storage unit 60.

[0037] [Communications Department] 1, the communication unit 40 connects the wearable terminal 1 and the host terminal 2, and communicates between the host terminal 2 and the management server 3 via a public communication line NW. In this embodiment, the communication unit 40 is composed of a short-range wireless module for connecting the wearable terminal 1 and the host terminal 2, and a communication module conforming to a communication standard (cellular system) such as LTE or 5G for communicating between the host terminal 2 and the management server 3. The communication unit 40 has a host terminal transmitting means 41 and a host terminal receiving means 42, as shown in FIG.

[0038] The host terminal transmission means 41 transmits to the management server 3 the information (worker position information 31 and behavior information 32) acquired by the wearable terminal 1 received from the wearable terminal transmission means 11. The worker position information 31 transmitted by the host terminal transmission means 41 is preferably the worker position information 31 estimated to have a small error by the error estimation means 51 described later. By selecting the worker position information 31 estimated to have a small error, unnecessary data (worker position information 31 estimated to have a large error) is not transmitted to the management server 3, and communication charges can be reduced. In addition, the host terminal transmission means 41 transmits to the management server 3, for example, the garbage collection point (collected garbage collection point candidate 61) determined to have been collected by the determination means 52 described later, the position information of the host terminal 2 (garbage collection truck position information acquired by the garbage collection truck position information acquisition means 53 described later), information on the garbage collection point input by the input means 55 described later, and the like.

[0039] The host terminal receiving means 42 receives information (worker position information 31 and behavior information 32) acquired by the wearable terminal 1 from the wearable terminal transmitting means 11. The host terminal receiving means 42 also receives information transmitted from the management server 3, such as a garbage collection point list 91 described later. It is preferable that the information transmitted from the management server 3, such as the garbage collection point list 91, is received automatically or manually on a regular basis. By receiving information (garbage collection point list 91) from the management server 3 in advance by the host terminal receiving means 42, the information of the garbage collection point list 91 can be used in the display means 54 and input means 55 described later even in places where GPS and radio waves cannot reach, such as underground parking lots and areas crowded with high-rise buildings. The worker position information 31, behavior information 32, garbage collection point list 91, and the like received by the host terminal receiving means 42 are stored in the memory unit 60.

[0040] [Processing section] The processing unit 50 includes an error estimation means 51 , a determination means 52 , a garbage collection vehicle position information acquisition means 53 , a display means 54 , and an input means 55 .

[0041] [Error estimation means] The error estimation means 51 estimates an error in the worker position information 31 transmitted from the wearable terminal transmission means 11. The method of estimating the error is not particularly limited, but for example, the error is estimated by performing processing such as a moving average method, outlier removal, and spike removal. Furthermore, if the coordinates of the acquired worker position information 31 are coordinates of a place where the worker needs to move at a speed faster than the worker's movement speed (for example, 12 m / s or more), it is estimated that the error in the acquired worker position information 31 is large. If there is worker position information 31 estimated to have a large error, it can be excluded from use in the determination means 52 and the determination means 81 described later, for example, by setting a flag.

[0042] [Judgment means] The determination means 52 determines whether or not garbage has been collected at a garbage collection point registered in the garbage collection point list 91. When a garbage collection point registered in the garbage collection point list 91 exists within a predetermined range based on a position specified from the worker position information 31, the determination means 52 determines that garbage at the garbage collection point has been collected. Therefore, since garbage at a garbage collection point is determined to have been collected when a worker approaches the garbage collection point to collect garbage, the worker does not need to select a garbage collection point that has already been worked on each time, which saves the worker time. In addition, it is preferable that the determination means 52 determines whether or not garbage has been collected at a garbage collection point registered in the garbage collection point list 91 based on the behavior information 32 in addition to the worker position information 31. With this configuration, the actions of the worker at the position identified from the worker position information 31 (the collection actions when the worker lifts up the garbage to collect it, the walking actions of the worker, etc.) become clear, and for example, a garbage collection point where a worker went to but did not collect garbage is not determined to have garbage collected, thereby improving the judgment accuracy of the judgment means 52. Garbage collection points determined to have garbage collected by the judgment means 52 (candidate garbage collection point where garbage has been collected 61) are stored in the memory unit 60 and displayed on the display means 54 as necessary. Note that the judgment by the judgment means 52 as to whether garbage has been collected can be made using a judgment method similar to that of the judgment means 81 in the management server 3 described later.

[0043] [Method of acquiring garbage collection vehicle location information] The garbage truck position information acquisition means 53 acquires position information indicating the current position of the host terminal 2. That is, in this embodiment, since the host terminal 2 is installed on the garbage truck 200, the position information indicating the current position of the host terminal 2 acquired by the garbage truck position information acquisition means 53 corresponds to the position information indicating the current position of the garbage truck 200 (garbage truck position information). The garbage truck position information acquisition means 53 acquires the garbage truck position information based on a positioning signal from a GPS, which is one of the GNSS (Global Navigation Satellite Systems). The garbage truck position information acquired by the garbage truck position information acquisition means 53 includes each data related to the position, such as latitude, longitude, and altitude. The garbage truck position information may also include information related to the time when the position information is acquired (date and time). When generating data related to the movement history of the garbage truck 200 in the data generating means 82 described below, the garbage truck position information acquiring means 53 is configured to automatically acquire the position information of the host terminal 2 at regular intervals, and the garbage truck position information is transmitted to the management server 3 by the host terminal transmitting means 41. By configuring the position information of the host terminal 2 to be automatically acquired at regular intervals, it is possible to obtain both the movement history of the worker and the movement history of the garbage truck 200. The garbage truck position information acquiring means 53 may also be configured to acquire the position information of the host terminal 2 through a specified operation of the host terminal 2 by the worker.

[0044] [Display means] The display means 54 is a display that displays the garbage collection points registered in the garbage collection point list 91 and the candidate garbage collection points 61 that have been collected and that have been determined by the determination means 52. For example, the garbage collection points registered in the garbage collection point list 91 are displayed on a map, and the candidate garbage collection points 61 that have been collected and that have been determined by the determination means 52 are colored or marked as having been collected, so that the worker can easily check the garbage collection points where the garbage has been collected. In addition, by displaying the candidate garbage collection points 61 that have been collected on the display means 54, if the worker finds a problem with a garbage collection point while collecting garbage, the worker can easily select the garbage collection point where the problem occurred. In addition, the display means 54 may display the garbage collection points that may have been forgotten to be collected on a map or in a list, together with the candidate garbage collection points 61 that have been collected.

[0045] Furthermore, the display means 54 can display the garbage collection points registered in the garbage collection point list 91 in a desired order. For example, the garbage collection points can be displayed in order of proximity to the current position (garbage collection point position information) of the garbage collection point 200 acquired by the garbage collection point position information acquisition means 53, or in alphabetical order. The garbage collection points registered in the garbage collection point list 91 may be searched for and displayed by keyword. In this way, by displaying the garbage collection points registered in the garbage collection point list 91 in a desired order in the display means 54, the worker can easily select a garbage collection point (garbage collection point with an automatic acquisition error) that was not determined to have been collected by the determination means 52 despite having actually been collected due to an error of the wearable terminal 1 or the like (such as a communication failure or a disturbance in position information due to sunspot activity).

[0046] [Input method] The input means 55 is a touch panel or the like for inputting information about the garbage collection point (for example, information about trouble at the garbage collection point and an automatically acquired error garbage collection point). The trouble information at the garbage collection point is a problem that a worker finds when collecting garbage at the garbage collection point, such as removal of garbage, illegal dumping, non-sorting, garbage that is not subject to collection being put out, the garbage collection point being vandalized by wild animals (cats, crows, wild boars, etc.), and a fire at the garbage collection point. The input of information about the garbage collection point is configured to be possible, for example, by selecting a target garbage collection point from the garbage collection points registered in the garbage collection point list 91, and inputting information using a keyboard and pull-down menu on an operation screen displayed on the display (display means 54). When a worker finds a trouble at the garbage collection point while collecting garbage, the worker can input the trouble information at the garbage collection point using the input means 55 and send the information to the management server 3. In addition, if there is a garbage collection point where garbage has actually been collected but has not been determined as having been collected by the determination means 52 (automatic acquisition error garbage collection point), the garbage collection point where garbage has been collected can be input by the input means 55 and the information can be sent to the management server 3.

[0047] [Storage section] The memory unit 60 is a storage built into the host terminal 2, and functions as a host terminal storage means for storing and saving various data. The memory unit 60 stores information acquired by the wearable terminal 1 received from the wearable terminal 1 (worker position information 31 and behavior information 32), the garbage collection point list 91 received from the management server 3, and collected garbage collection point candidates 61 determined to have been collected by the determination means 52, and these are read out as necessary.

[0048] <Administration Server> The management server 3 manages information related to waste collection points and is connected to the host terminal 2. The management server 3 is mainly composed of a computer equipped with a CPU, memory, storage, etc. The management server 3 is preferably a cloud server, but may also be installed in the office of the local government or company that operates the waste collection status management system 100.

[0049] The management server 3 includes a communication unit 70, a processing unit 80, and a storage unit 90.

[0050] [Communications Department] 1, the communication unit 70 communicates between the host terminal 2 and the management server 3 via a public communication line NW. In this embodiment, the communication unit 70 is configured with, for example, a wired LAN module, a wireless LAN module, or a communication module that complies with a communication standard (cellular system) such as LTE or 5G. As shown in FIG. 2, the communication unit 70 has a management server transmitting means 71 and a management server receiving means 72.

[0051] The management server transmission means 71 transmits the latest garbage collection point list 91 to the host terminal 2. The management server transmission means 71 transmits the garbage collection point list 91 to the host terminal 2 as necessary, such as when a new garbage collection point is registered in the garbage collection point list 91 or at a set time of day (before the start of a day).

[0052] The management server receiving means 72 receives information (worker position information 31 and behavior information 32) acquired by the wearable terminal 1 from the host terminal transmitting means 41. In addition, the management server receiving means 72 receives, for example, collected waste collection site candidate 61 determined to have been collected by the determining means 52, position information of the host terminal 2 (garbage collection vehicle position information acquired by the garbage collection vehicle position information acquiring means 53), input information input from the input means 55, etc.

[0053] [Processing section] The processing unit 80 includes a determination unit 81 , a data generation unit 82 , and an image generation unit 83 .

[0054] [Judgment means] The determination means 81 determines whether or not garbage has been collected at a garbage collection point registered in the garbage collection point list 91. When a garbage collection point registered in the garbage collection point list 91 exists within a predetermined range based on a position specified from the worker position information 31, the determination means 81 determines that garbage at the garbage collection point has been collected. Therefore, since garbage at a garbage collection point is determined to have been collected when a worker approaches the garbage collection point to collect garbage, the worker does not need to select a garbage collection point that has already been worked on each time, which saves the worker time. In addition, it is preferable that the determination means 81 determines whether or not garbage has been collected at a garbage collection point registered in the garbage collection point list 91 based on the behavior information 32 in addition to the worker position information 31. With this configuration, the actions of the worker at the position specified by the worker position information 31 (collecting actions when the worker lifts up and collects garbage, walking actions of the worker, etc.) become clear, and for example, a garbage collection point where a worker went to but did not collect garbage is not determined to have garbage collected, so that the accuracy of the determination means 81 can be improved. In the garbage collection status management system 100 of this embodiment, the determination means 52 is provided in the host terminal 2, and the determination means 81 is provided in the management server 3. Therefore, the determination means 81 may determine a garbage collection point where garbage has been collected based on information on the collected garbage collection point candidate 61 determined to have been collected by the determination means 52. Note that a configuration in which only one of the determination means 52 and the determination means 81 is provided may be adopted.

[0055] It is preferable that the determination means 81 finds a concentration point of the coordinates of the worker position information 31. When a worker collects garbage, he stops walking to collect garbage, so the coordinates of multiple worker position information 31 are concentrated at the place where he stopped walking. Therefore, by finding the concentration point of the coordinates of the worker position information 31, it becomes clear where the worker is heading and where he is stopped. In addition, it is preferable that the determination means 81 determines the collection action when the worker lifts up and collects garbage from the behavior information 32. For example, a temporary decrease in vertical movement, a movement such as strongly bending the arms forward, a change in acceleration, etc., which are typically observed when the worker stops walking, bends down to pick up garbage, or stands up to lift up garbage, so a score is assigned to each of these actions, and when the total score exceeds a threshold, it is determined that there is a high possibility that the collection action has been performed. Based on this information, the determination means 81 can determine that garbage has been collected at a garbage collection site when a collection operation is performed at the convergence point of the coordinates of the worker position information 31, for example, and can more accurately determine the garbage collection site that the worker approached to collect garbage.

[0056] In addition, the determination means 81 may determine whether or not garbage has been collected at a garbage collection point registered in the garbage collection point list 91 by using an algorithm that has been machine-learned in advance using sample data (sensor waveforms and labeled actual actions) of the worker position information 31 and behavior information 32 from the previous day as learning data. If a worker stops walking near a garbage collection point or turns around, the possibility that the worker is actually collecting garbage increases. Therefore, by weighting these actions during machine learning, it is possible to quickly and efficiently determine the garbage collection point where garbage has been collected. In addition, by learning a model that classifies and identifies specific behavior patterns during machine learning, the determination accuracy of the determination means 81 is improved and it can also be used to determine whether or not there has been a problem.

[0057] In this embodiment, the predetermined range is preferably within a radius of 50 m from the position identified from the worker position information 31, more preferably within a radius of 10 m, and particularly preferably within a radius of 5 m. By setting the predetermined range to the above range, it is possible to more accurately determine the garbage collection site that the worker approached to collect garbage. In addition, it is preferable that the predetermined range is set according to the frequency at which the worker position information acquisition means 21 acquires the worker position information. For example, when the worker position information acquisition means 21 acquires the worker position information 31 every short time (for example, every 1 to 10 seconds), the predetermined range is set to a short distance range (for example, within a radius of 10 m from the position identified from the worker position information 31), and when the worker position information acquisition means 21 acquires the worker position information 31 at a certain interval (for example, every 20 to 30 seconds), the predetermined range is set to a wide range (for example, within a radius of 50 m from the position identified from the worker position information 31). In this way, the predetermined range is set according to the frequency with which the worker position information acquisition means 21 acquires the position information of the worker, so that it is possible to accurately determine the garbage collection point that the worker approached to collect garbage. Furthermore, if there are multiple garbage collection points registered in the garbage collection point list 91 within the predetermined range, the determination means 81 may determine that garbage from the nearest garbage collection point has been collected. Furthermore, the determination means 81 may have a function to correct the predetermined range, for example, taking into account the curvature of the earth. By having such a correction function, it is possible to more accurately select the garbage collection point where garbage has been collected.

[0058] The predetermined range used by the determination means 81 when determining that garbage at a garbage collection point has been collected is preferably set in a plurality of stages. By setting the predetermined range in a plurality of stages, it is possible to rank the garbage collection points, for example, by assigning "A" to a garbage collection point where garbage has been collected with certainty, "B" to a garbage collection point where garbage has been collected with a high probability, and "C" to a garbage collection point where garbage has been collected even if it is within the predetermined range. FIG. 3 is a conceptual diagram of the determination of a garbage collection point in the garbage collection status management system 100 of this embodiment. In the example shown in FIG. 3, garbage collection points 91a to 91c are registered in a certain collection area in the garbage collection point list 91, and the predetermined range based on the position P identified from the worker position information 31 is set in three stages, A to C. In this case, the determination means 81 determines that the garbage collection point 91a that exists within the predetermined range A is "garbage collected (A)". The garbage collection point 91b does not exist within the predetermined range A, but exists within the predetermined range B, and therefore determines that "garbage has been collected (B)". Although garbage collection point 91c is not within the ranges A and B, it is within the range C, and so is determined to be "garbage collected (C)." In this way, among the garbage collection points determined to have had garbage collected, it becomes clear which have had garbage collected reliably and which have not, and more accurate garbage collection status data 92 can be obtained.

[0059] [Method of data generation] The data generating means 82 generates garbage collection status data 92 that associates the garbage collection points determined by the determining means 81 to have garbage collected with the garbage collection status. The garbage collection status includes "garbage not collected" indicating that garbage collection has not yet been completed and "garbage collected" indicating that garbage has been collected, and the garbage collection status data 92 is generated from an initial state in which the garbage collection status of all garbage collection points registered in the garbage collection point list 91 on the garbage collection day is "garbage not collected". The data generating means 82 generates garbage collection status data 92 that associates the garbage collection points determined by the determining means 81 to have garbage collected with the garbage collection status of "garbage collected". In addition, by generating garbage collection status data 92 that associates the collected garbage collection points input by the input means 55 with the garbage collection status together with the garbage collection points determined by the determining means 81 to have garbage collected, more accurate garbage collection status data 92 can be generated. The generated garbage collection status data 92 is stored in the memory unit 90.

[0060] [Image generation means] The image generating means 83 generates an image for displaying data indicating, for example, how many of the garbage collection points in a given area have been collected for each day on a display device (not shown) installed in a location where the garbage collection headquarters, the local government manager, or the administrative manager can confirm the data, based on the garbage collection status data 92 generated by the data generating means 82. It is preferable that the image shows the daily data for the given area in real time. The generated image is transmitted from the communication unit 70 to the display device.

[0061] [Storage section] The memory unit 90 is a storage in a computer, and functions as a management server storage means for storing and saving various data. The memory unit 90 stores a garbage collection point list 91 that associates garbage collection points registered in advance with the location information of the garbage collection points, and the list is read out as necessary. The memory unit 90 also stores garbage collection status data 92 generated by the data generating means 82. The memory unit 90 may also store information (worker location information 31 and behavior information 32) acquired by the wearable terminal 1 and transmitted from the host terminal 2, as well as the garbage collection truck location information, the date and time when the worker location information 31, the behavior information 32, and the garbage collection truck location information were acquired, and the terminal name of the host terminal 2 (garbage collection truck name). By storing this information, the information of the wearable terminal 1 and the host terminal 2 can be displayed on a map at a later date, and the collection history for each garbage collection truck 200 can be reviewed.

[0062] The garbage collection point list 91 associates a garbage collection point with at least the location information of the garbage collection point. For example, the garbage collection point list 91 associates an image, a garbage collection point name, an address, and registration information with the location information of the garbage collection point. The garbage collection point list 91 is registered in advance. It is preferable that the location information, image, garbage collection point name, and address of the registered garbage collection point can be edited later. By configuring the information registered in the garbage collection point list 91 to be editable later, even if there is an error in the location information of the garbage collection point or the location of the garbage collection point has changed, corrections can be made, thereby improving the accuracy and reliability of the garbage collection point list 91. The garbage collection point list 91 can have any data structure.

[0063] <Operation of the garbage collection status management system> Fig. 4 is a flowchart showing the procedure for waste collection status management implemented in the waste collection status management system 100 of this embodiment. The procedure for waste collection status management will be described below with reference to Fig. 4. The symbol "S" in Fig. 4 denotes a step. The procedure shown in the flowchart in Fig. 4 starts on the waste collection day when the waste collection status data 92 is in the initial state, that is, when the waste collection status of all waste collection points is "waste not collected," and is repeatedly executed at a predetermined cycle time at least during the time period when waste collection work is performed.

[0064] <S101~S102> When the wearable terminal 1 is not connected to the host terminal 2 (S101: NO), the wearable terminal 1 acquires information (S102). The information acquired by the wearable terminal 1 includes worker position information 31 acquired by the worker position information acquisition means 21 and behavior information 32 acquired by the detection means 22. When the wearable terminal 1 is connected to the host terminal 2 (S101: YES), the process returns. By acquiring information by the wearable terminal 1 only while the wearable terminal 1 and the host terminal 2 are not connected, unnecessary data is not acquired, and therefore power consumption of the wearable terminal 1 can be reduced.

[0065] <S103~S105> Thereafter, when the wearable terminal 1 is connected to the host terminal 2 (S103: YES), the wearable terminal transmission means 11 transmits the information acquired by the wearable terminal 1 (worker position information 31 and behavior information 32) to the host terminal 2 (S104), and returns the process to S101. When the wearable terminal 1 is not connected to the host terminal 2 (S103: NO), the information acquired by the wearable terminal 1 is stored in the storage unit 30 (S105), and returns the process to S102. Note that, when the wearable terminal 1 is connected to the host terminal 2 (S103: YES) in a state in which the information acquired by the wearable terminal 1 is stored in the storage unit 30, the wearable terminal transmission means 11 transmits the information acquired by the wearable terminal 1 stored in the storage unit 30 together to the host terminal 2. By repeating the processes of S101 to S105, the wearable terminal 1 operates to periodically transmit the information acquired by the wearable terminal 1 to the host terminal 2.

[0066] <S201~S204> In the host terminal 2, the host terminal receiving means 42 receives the information (worker position information 31 and behavior information 32) acquired by the wearable terminal 1 transmitted from the wearable terminal 1 (wearable terminal transmitting means 11) (S201). Next, the error estimating means 51 estimates the error of the worker position information 31 received in S201 (S202), and the determining means 52 determines whether or not garbage has been collected at the garbage collection point registered in the garbage collection point list 91 (S203). After that, the host terminal transmitting means 41 transmits the garbage collection point information to the management server 3 (S204). The garbage collection point information includes the information (worker position information 31 and behavior information 32) acquired by the wearable terminal 1 received in S201, the garbage collection point candidate 61 where garbage has been collected and determined in S203, and the input information input from the input means 55. It is preferable that the worker position information 31 estimated to have a large error in S202 is excluded from the garbage collection point information transmitted to the management server 3 in S204. By repeating the processes of S201 to S204, the host terminal 2 operates to transmit the garbage collection point information including the information acquired by the wearable terminal 1 (the worker position information 31 and the behavior information 32) to the management server 3.

[0067] <S301~S303> In the management server 3, the management server receiving means 72 receives the garbage collection point information transmitted from the host terminal 2 (host terminal transmitting means 41) (S301). Next, the determination means 81 determines whether or not garbage has been collected at the garbage collection point registered in the garbage collection point list 91 (S302). For a collected garbage collection point, i.e., a garbage collection point determined in S302 for which garbage has been collected, the garbage collection status of "garbage not yet collected", which indicates that garbage collection has not yet been completed in the initial state of the garbage collection status data 92 for that garbage collection point, is switched to a garbage collection status of "garbage collected", which indicates that garbage has been collected, and generates garbage collection status data 92 that associates a garbage collection point determined by the determination means 81 for which garbage has been collected with the garbage collection status of "garbage collected" (S303). By repeating the processes of S301 to S303, the management server 3 operates to update the garbage collection status data 92 every time garbage collection point information is received from the host terminal 2.

[0068] In the waste collection status management system 100 of this embodiment, the information acquired by the wearable terminal 1 (worker position information 31 and behavior information 32) is transmitted to the host terminal 2, and is transmitted from the host terminal 2 to the management server 3 via the public communication line NW. When a waste collection point registered in the waste collection point list 91 exists within a predetermined range based on the position specified by the worker position information 31, the management server 3 determines that the waste at the waste collection point has been collected. Therefore, since the information acquired by the wearable terminal 1 is used to determine whether the waste at the waste collection point has been collected when the worker approaches the waste collection point to collect the waste, the worker does not need to select the waste collection point that has already been worked on every time, which saves the worker time. Then, the waste collection status data 92 is generated, which associates the waste collection status with the waste collection point determined by the determination means 81 as having collected the waste. The waste collection status data 92 can be easily obtained. [Industrial Applicability]
