Description

[Technical field]

[0001] The present invention relates to a system for confirming the exit of objects that have entered an entrance / exit area, and is used, for example, to confirm the exit of children who have boarded a kindergarten or nursery school shuttle bus. [Background technology]

[0002] Recently, there have been many cases of kindergarten and nursery school children being left locked inside shuttle buses for long periods of time because drivers forget to check, resulting in deaths from heatstroke and other causes.

[0003] Therefore, in order to prevent such accidents from occurring, a system that can prevent people from being trapped inside a vehicle is desired.

[0004] For example, technology has already been proposed that can count the number of people in spaces where people enter and exit, such as floors, by installing detection mats that detect footstep pressure at entrances and exits on each floor of a building, counting the number of people passing through by footstep pressure on the mat, and tallying up the number of people on each floor (see Patent Document 1).

[0005] However, the above technology has a problem in that it is difficult to count the number of people when multiple people enter and exit at the same time.

[0006] On the other hand, a system has also been proposed that measures the change in weight inside the elevator car when it stops at each floor, and a decrease in weight inside the elevator car is considered to be an entry to that floor, and an increase in weight inside the elevator car is considered to be an exit from that floor, and calculates the number of people entering and leaving each floor from the weight change and average weight to estimate the number of people occupying each floor (see Patent Document 2). [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Japanese Patent Application Publication No. 3-196286 [Patent Document 2] Patent No. 5091544 Summary of the Invention [Problem to be solved by the invention]

[0008] However, the system in Patent Document 2 works by attaching a weight measuring device to the elevator car and managing the total weight of people inside the car, thereby enabling it to grasp increases and decreases in weight. This weight measuring device is large in size, and there is a problem in that modifying existing elevators would require major renovation work, which would be too costly.

[0009] The present invention has been made in consideration of the above-mentioned problems, and aims to provide an entrance / exit management system that enables an administrator to quickly grasp and deal with an abnormality in the number of entrants entering an entrance / exit location, relative to the remaining number of entered items set at the end of measurement, without making major modifications to existing equipment. [Means for solving the problem]

[0010] In order to achieve the above-mentioned object, the entrance / exit management system of the present invention is an entrance / exit management system that manages the amount of entrances and exits at an entrance / exit location, and is characterized in that it is provided with a weight measuring device at the entrance / exit of the entrance / exit location, measures the weight of each entrance / exit item entering and exiting the entrance / exit location, while determining an entrance / exit category indicating whether the item is entering the entrance / exit location or exiting from the entrance / exit location, measures the total weight of the entrance / exit items entering the entrance / exit location at any time from the start of measurement to the end of measurement using the entrance / exit category, and issues a warning when the total weight of the entrance / exit items at the end of measurement is equal to or greater than a preset weight.

[0011] In the entrance / exit management system of the present invention, examples of entrance / exit locations include automobiles including shuttle buses where passengers get on and off, gymnasiums, concert halls, warehouses, and the like.

[0012] In the entrance / exit management system of the present invention, the entrances and exits include people and goods.

[0013] In the entrance / exit management system of the present invention, the end of measurement can be, for example, when the entrance / exit location is a shuttle bus, the time when the bus arrives at the final stop and passengers have finished disembarking.

[0014] The entrance / exit management system of the present invention is preferably used in shuttle buses that transport kindergarten children, nursery school children, people attending nursing homes, and people attending care facilities. In other words, if a passenger such as a kindergartener, nursery schooler, or care facility attendee, who has difficulty getting off the bus on his / her own, is left behind on the shuttle bus, the manager (e.g., the driver or school principal) can quickly notice this, and the occurrence of a so-called "left-behind" accident can be avoided.

[0015] In the entrance / exit management system of the present invention, when the entrance / exit location is a shuttle bus, it is preferable that the weight measuring device is provided on a step of the shuttle bus.

[0016] That is, by providing a weight measuring device on the steps of the shuttle bus, the weight of passengers getting on and off the shuttle bus can be reliably obtained.

[0017] Furthermore, when weight measuring devices are provided at the steps, it is more preferable to provide weight measuring devices at two or more of the multiple steps.

[0018] In other words, by doing as described above, it is possible to determine whether a passenger is getting on or off the train depending on the order in which the passengers step on the weight measuring devices. In addition, the entrance / exit management system of the present invention may be configured so that a shuttle bus has multiple stops between the start and end of measurement, and a warning is issued if the total weight of passengers after disembarking at each stop is outside a preset threshold value of the total weight at the time of departure from each stop. In other words, by doing as described above, it is possible to immediately grasp the incorrect boarding and alighting status at each bus stop, and to provide safer pick-up and drop-off services.

[0019] The weight measuring device is not particularly limited, but for example, there is an air mat device with a weight measuring function described in JP 2018-29877, that is, when the mat is stepped on, the metal inside the device bends, and the resistance value of the "strain gauge" attached to the metal changes, and this is used to measure weight. In addition to the method using the "strain gauge", there is also a mechanism in which pressure is applied to the liquid filled inside the device when the mat is stepped on with the foot, and weight is measured from the pressure. As disclosed in https: / / www.amazon.co.jp / Weight-Scale-Insmart-Body-Fat-Scale-Body-Composition-Scale-Smartphone-Linked-FG260 / dp / B082SQX6TD?th=1, a weight scale with a communication function with a smartphone or the like can also be used. Effect of the Invention

[0020] As described above, the entrance / exit management system of the present invention is a management system that manages the amount of entrances and exits at an entrance / exit point where the entrance / exit points are used, and a weight measuring device is provided at the entrance / exit point to measure the weight of each entrance / exit point that enters and leaves the entrance / exit point, while the total weight of the entrance / exit points that enter the entrance / exit point is measured continuously from the start of measurement to the end of measurement, and a warning is issued if the total weight of the entrance / exit points at the end of measurement is equal to or greater than a preset weight, so that the administrator of the entrance / exit point can minimize the risk of overlooking an abnormality in the situation in which entrance / exit points are entering. Moreover, since it is only necessary to provide a weight measuring device at the entrance / exit point, existing equipment can be easily modified. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings as appropriate. However, the present invention is not limited to the following embodiment, and appropriate modifications can be made without departing from the gist of the present invention.

[0023] (First embodiment) An entrance / exit control system 100 according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 6. FIG.

[0024] As described in detail below, this entry / exit management system 100 manages the entry and exit of the shuttle bus 50 as the entry / exit point, i.e., the boarding and disembarking of children K from kindergartens, nursery schools, or child care centers (hereinafter referred to simply as "schools") as passengers, which are the entry objects (the number of entry and exit objects), and prevents children from being left behind in the following manner.

[0025] The entrance / exit management system 100 includes an information processing device 10, three weight measuring devices 20a, and two mobile terminals 30a and 30b.

[0026] The information processing device 10 is capable of communicating with the weight measuring device 20a and the mobile terminals 30a, 30b via a communication line 40, and is configured to manage the boarding and disembarking status of the child K on the shuttle bus 50 using the weight measured by the weight measuring device 20a.

[0027] The weight measuring device 20a is in the form of a mat that is individually and removably installed on the three steps (entrances and exits of the entrance and exit area) of the shuttle bus 50, and each device is equipped with a measuring unit 201 and a transmitting unit 202, as shown in Figure 5.

[0028] The measuring unit 201 is capable of measuring the weight of the child K who steps on the steps when getting on and off the car.

[0029] The transmitting unit 202 transmits the weight information measured by the measuring unit 201 and an identifier individually set for each weight measuring device 20a to the information processing device 10. The identifier is an ID for identifying each weight measuring device 20a, and is stored in a storage unit (not shown) of each weight measuring device 20a.

[0030] In other words, when a load is applied to each weight measuring device 20a, the identifier is transmitted from the transmitting unit 202 of each weight measuring device 20a to the information processing device 10, and is used to determine the entry / exit classification, as described below.

[0031] When the information processing device 10 judges that an abnormality has occurred, the mobile terminals 30a and 30b output a warning on their screens.

[0032] Of the two mobile terminals 30a, 30b, one mobile terminal 30a is carried by the driver or placed in a position where the driver can immediately see the warning, and the other mobile terminal 30b is carried by the person in charge of transportation management on that day (which may be the principal of the kindergarten) or placed in a position where the driver can immediately see the warning.

[0033] In addition, of the two mobile terminals 30a and 30b, one mobile terminal 30a has a GPS function and is configured to return location information in response to a request from the determination information acquisition unit 1012 of the information processing device 10. That is, the GPS location information sent to the information processing device 10 becomes the location information of the shuttle bus 50.

[0034] The mobile terminals 30a and 30b display a warning, which will be described later, output from the information processing device 10 (see FIG. 4(a)).

[0035] In addition, when measurement starts, the mobile terminal 30a displays a childcare worker boarding completion button 301 (see Figure 4 (b)) on its screen, and when the childcare worker boarding completion button 301 is pressed, it transmits a message to that effect to the information processing device 10.

[0036] As shown in FIG. 2, the information processing device 10 includes a receiving unit 101, a storage unit 102, a processing unit 103, and an output unit 104.

[0037] The receiving unit 101 receives the weight of the child K transmitted from the weight measuring device 20a.

[0038] The weight information of the child K transmitted from the weight measuring device 20a may be either the weight information of one child K or the total weight information of multiple children K who board (or disembark) the shuttle bus 50 at the same time.

[0039] The receiving unit 101 also includes a weight receiving unit 1011 that receives the weight of each child K, and a judgment information acquiring unit 1012 that acquires information for determining the start and end of measurement of the total weight of the children K on the shuttle bus 50.

[0040] When receiving the weight information of child K, the weight receiving unit 1011 also receives an identifier that identifies the weight measuring device 20a in order to distinguish whether child K is boarding or disembarking from the shuttle bus 50.

[0041] The judgment information acquisition unit 1012 is configured to acquire the location information of the mobile terminal 30a and obtain it as the location information of the shuttle bus 50, and also to acquire information as to whether the childcare worker boarding completion button 301 provided on the mobile terminal 30a has been pressed.

[0042] The storage unit 102 temporarily stores the total weight, the information received by the weight receiving unit 1011, and the information acquired by the determination information acquiring unit 1012 at any time.

[0043] The processing unit 103 measures the total weight of the children K on the shuttle bus 50 by adding and subtracting the received weight.

[0044] That is, the processing unit 103 includes a boarding / disembarking determination unit 1031 , a total weight measurement unit 1032 , a determination unit 1033 , and a warning generation unit 1034 .

[0045] The boarding / disembarking determination unit 1031 is configured to determine boarding / disembarking using the identifiers of the weight measuring devices 20a received from the transmission units 202 of the three weight measuring devices 20a.

[0046] In other words, when the identifiers of the lower tier weight measuring device 20a are received in the order of the identifier of the upper tier weight measuring device 20a, it is determined that the passenger has boarded the vehicle, and when the identifiers of the upper tier weight measuring device 20a are received in the order of the identifier of the lower tier weight measuring device 20a, it is determined that the passenger has disembarked, so that the entry / exit category can be determined.

[0047] The total weight measuring unit 1032 adds the weight of child K to the total weight if the category determined by the boarding / disembarking determination unit 1031 is "boarding", and subtracts the weight of child K from the total weight if the category is "disembarking", and rewrites and stores the total weight in the memory unit 102 as necessary.

[0048] The weight of each child K may be the average value of the weights sent from the weight measuring devices 20a of each step, or the measured value of the weight measuring device 20a that is stepped on first when getting on and off the car.

[0049] The total weight measuring unit 1032 measures the total weight at any time from the start of measurement to the end of measurement. The total weight measuring unit 1032 measures the total weight every time the weight receiving unit 1011 receives the weight of the child K (at any time).

[0050] The total weight measurement unit 1032 determines that the measurement start time has arrived when the judgment information acquisition unit 1012 acquires information that the childcare worker boarding completion button 301 has been pressed on the mobile terminal 30a, and measures the total weight based on the weight received after it has determined that the measurement start time has arrived. In other words, even if the nursery teacher repeatedly gets on and off the shuttle bus 50 to allow child K to board and disembark at the bus stops, the weight of the child is offset, so by determining the start time of the measurement as described above, only the weight of child K is measured as the total weight.

[0051] In addition, the total weight measuring unit 1032 is configured to determine that the measurement is completed when the location information of the weight measuring device 20a acquired by the judgment information acquisition unit 1012 is location information of the "location where the shuttle bus 50 ends the shuttle service" and a predetermined time has elapsed since the acquisition of the location information.

[0052] Here, the "location where the shuttle bus 50 ends the transfer" refers to the location where the shuttle bus 50 ends the transfer (the bus stop where all the children get off, the drop-off location at the nursery, or the bus parking lot at the nursery), and the predetermined time is, for example, two minutes. Both are stored in the memory unit 102 and can be set.

[0053] The determination unit 1033 is adapted to determine that a warning should be issued when the total weight at the end of measurement is equal to or greater than a preset weight.

[0054] Here, the total weight at the end of measurement is the total weight stored in the memory unit 102 when the total weight measuring unit 1032 determines that the measurement is ended. Note that the preset weight is zero, but since an error may occur in the weight measured by the weight measuring device 20a, the preset weight may be 5 kg.

[0055] The warning generation unit 1034 refers to the total weight stored in the memory unit 102 and a preset weight, and generates a warning such as "The total weight is __ kg, and the preset weight is __ kg. There is a risk that a child may have been left behind on the shuttle bus. Please check."

[0056] The output unit 104 outputs the above-mentioned warning on the screen of the mobile terminal 30a, 30b via the communication line 40 (see FIG. 4).

[0057] When the above warning message is output to the mobile terminals 30a and 30b, a confirmation button 1041 is simultaneously displayed on the screen.

[0058] The output unit 104 continues to output the warning until it receives an input from the mobile terminals 30a and 30b indicating that the warning has been confirmed. This makes it possible to prevent the administrator from overlooking or missing the warning as much as possible.

[0059] The output unit 104 can output audio as well as display on the screen of the mobile terminal 30a, 30b. By outputting audio, the output unit 104 can make the driver, who cannot see the warning because he is driving, aware of the warning.

[0060] The transmission unit 202 transmits the weight of the child K measured by the measurement unit 201, the identifier of the weight measuring device 20a, and is transmitted to the information processing device 10.

[0061] Next, the management operation of this entrance / exit management system 100 will be described with reference to the processing flow of the information processing device 10 (see FIG. 3).

[0062] (Step 1) When child K gets on or off the shuttle bus 50, child K steps on the weight measuring device 20a on the step. When child K steps on the weight measuring device 20a, the measurement unit 201 measures child K's weight. The transmission unit 202 transmits the weight and the identifier of the weight measuring device 20a to the information processing device 10. The weight receiving unit 1011 of the information processing device 10 receives the weights and the identifiers of the weight measuring devices 20a successively from the three weight measuring devices 20a, and temporarily stores them in the memory unit 102.

[0063] (Step 2) The boarding / disembarking determination unit 1031 determines whether the passenger is boarding or disembarking based on the identifier of the weight measuring device 20a stored in the storage unit 102.

[0064] (Step 3) The determination information acquisition unit 1012 acquires, from the mobile terminal 30a, determination information for determining the start and end of measurement of the total weight.

[0065] (Step 4) The total weight measuring unit 1032 judges whether it is the start of measurement or the end of measurement based on the information acquired by the judgment information acquisition unit 1012. If it is the start of measurement, the total weight measuring unit 1032 resets the total weight stored in the memory unit 102. The total weight measuring unit 1032 measures the total weight based on the weight received from the weight measuring device 20a and the boarding / disembarking category determined by the boarding / disembarking determination unit 1031. The total weight measuring unit 1032 adds to the total weight if the passenger is boarding, and subtracts from the total weight if the passenger is disembarking.

[0066] (Step 5) The determination unit 1033 determines whether or not to issue a warning depending on whether the total weight at the end of the measurement is equal to or greater than a preset weight.

[0067] If it is determined that a warning should not be issued (NO in S5), the process ends. If it is determined that a warning should be issued (YES in S5), the next step is executed.

[0068] (Step 6) The warning generation unit 1034 generates a warning message (S6).

[0069] (Step 7) The output unit 104 outputs the warning message to the mobile terminals 30a and 30b. The manager checks the warning (see FIG. 5) output to the mobile terminals 30a and 30b and confirms whether the child K has been left behind on the shuttle bus 50.

[0070] As described above, this entry / exit management system 100 measures the total weight of child K aboard the shuttle bus 50 from the start to the end of the measurement, and issues an alarm when the total weight of child K at the end of the measurement is equal to or greater than a preset weight, thereby reducing the risk that the administrator will overlook the situation where child K has been left behind on the shuttle bus 50.

[0071] In addition, since a commercially available weighing scale having a communication function with a smartphone or the like as described above can be used as the weight measuring device 20a, the system can be constructed inexpensively without extensively modifying the shuttle bus 50.

[0072] Furthermore, since the weight measuring device 20a is detachable, a broken weight measuring device 20a can be immediately replaced, providing a high level of robustness as an entrance / exit management system.

[0073] (Modification of the first embodiment)

[0074] In the entrance / exit management system 100 according to the first embodiment, the information processing device 10 acquires the location information of the shuttle bus 50 by the GPS function of the mobile terminal 30a, but this is not limited to the above. For example, the shuttle bus may have a GPS function, or one of the weight measuring devices 20 may have a GPS function.

[0075] The weight measuring device 20a of the entrance / exit management system 100 according to the first embodiment is provided on each of the three steps of the shuttle bus 50, and all of the weight measuring devices 20a transmit weight to the information processing device 10, but this is not limited to the above. The weight measuring devices 20a may be provided on any two steps out of the three steps of the shuttle bus 50, and dummy mats may be laid on the other steps. By providing two weight measuring devices 20a, the entrance / exit management system 100 can be provided at low cost.

[0076] The entrance / exit management system 100 according to the first embodiment has three weight measuring devices 20a with the same functions on each step, but is not limited to this. For example, the weight measuring device 20a may be placed on only one step, and mats that can transmit only an identifier when stepped on may be placed on the other steps. In this way, the entrance / exit management system 100 can be constructed at low cost because only one weight measuring device 20a with complex functions is required.

[0077] In the entrance / exit management system 100 according to the first embodiment, the weight measuring device 20a is detachable from the step of the shuttle bus 50, but the weight measuring device may be embedded directly under the step of the shuttle bus 50. By embedding the device directly under the step, there is no need to worry about the device slipping off even if a child K steps on it with his / her foot.

[0078] In the entrance / exit management system 100 according to the first embodiment, the communication between the three weight measuring devices 20a, the two mobile terminals 30, and the information processing device 10 is performed via the communication line 40, but this is not limited to the above. The communication may be performed by short-range wireless communication. In this way, regardless of communication failure or communication delay on the communication line 40, the information processing device 10 can receive the weight from the weight measuring device 20a and issue a warning to the mobile terminal 30.

[0079] In the entrance / exit management system 100 according to the first embodiment, the warnings output to the mobile terminals 30a and 30b were the same, but they may be different. The warning to the mobile terminal 30b used by the principal may be "There is a risk that a child has been left behind on the shuttle bus. Please check," with an additional warning urging the principal to contact the driver. In this way, even if the driver overlooks it, the principal can notify the driver that a child has been left behind.

[0080] In the entrance / exit management system 100 according to the first embodiment, the warnings are output to the mobile terminals 30a and 30b at the same timing, but they may be output at different times. If the output unit 104 does not confirm the confirmation button input of the mobile terminal 30a even after a predetermined time has elapsed after outputting the warning, the warning may be output to the mobile terminal 30b. By warning the principal, it is possible to prevent the driver from overlooking the problem as much as possible.

[0081] Second embodiment The entrance / exit management system 200 of the second embodiment differs from the entrance / exit management system 100 in that, whereas the entrance / exit management system 100 determines in the determination unit 1033 whether the total weight of the children K at the end of measurement is equal to or greater than a preset weight, the determination unit 1033 of the entrance / exit management system 200 determines whether to issue a warning when the children finish getting off at each stop (or when the bus departs from the stop), as described below. The entrance / exit management system 200 will be explained below, focusing on the differences.

[0082] That is, in this entrance / exit management system 200, the storage unit 102 stores the post-disembarkation weight data 102a (see FIG. 6).

[0083] The shuttle bus 50 has two routes: (1) a drop-off route (child K boards at the nursery, gets off at a bus stop, and returns to the nursery) and (2) a pick-up route (leaves the nursery, gets child K boarded at a bus stop, returns to the nursery, and gets child K off). The post-disembarkation weight data 102a is data regarding the total weight inside the shuttle bus 50 after child K has disembarked at each bus stop on the (1) drop-off route.

[0084] The post-disembarking weight data 102a is data that is prepared in advance and is configured for each bus stop from bus stop position information 102a1, disembarking time 102a2, total weight at departure from the bus stop 102a3, and disembarking child information 102a4.

[0085] The bus stop location information 102a1 is the latitude and longitude information of the bus stop, such as the entrance to an apartment building or an intersection. The disembarking time 102a2 is the time when the child K disembarks from the shuttle bus 50 at that bus stop. The total weight at departure from the bus stop 102a3 is the total weight of the child K remaining in the shuttle bus 50 after the child K disembarks at that bus stop. The disembarking child information 102a4 is the name and weight of the child K who disembarks at that bus stop.

[0086] In this entrance / exit management system 200, the judgment unit 1033 compares the total weight of the children K after disembarking with the total weight at departure from the bus stop 102a3, and judges whether the difference is outside the threshold value.

[0087] The determination unit 1033 (Total weight of child K after disembarking - Total weight at departure from stop 102a3) > Threshold or (Total weight at departure from stop 102a3 - Total weight of child K after disembarking) > Threshold In such cases, it is judged that a warning should be issued. The threshold value corresponds to the weight of one child K, and is set to, for example, 20 kg. The threshold value is stored in the storage unit 102 and can be set by the administrator.

[0088] The warning generation unit 1034 generates the following warnings depending on the case.

[0089] (Total weight of child K after disembarking - Total weight at departure from the bus stop 102a3) > Threshold The warning generation unit 1034 refers to the disembarking child information 102a4 and generates a warning saying, "The total weight of the children currently on the shuttle bus 50 is __kg, and the weight at the time of departure from this stop is estimated to be __kg. There may be children who have forgotten to disembark. Please check. The children who will be disembarking at this stop are Tokkyo Jiro and Isho Hanako." (Total weight at departure from stop 102a3 - Total weight of child K after disembarking) > Threshold The warning generation unit 1034 refers to the disembarking child information 102a4 and generates a warning saying, "The total weight of the children currently on the shuttle bus 50 is __kg, and the weight at the time of departure from this stop is estimated to be __kg. Some children may have disembarked by mistake. Please check. The children who will be disembarking at this stop are Tokkyo Jiro and Isho Hanako."

[0090] The warning generation unit 1034 can also output the drop-off time 102a2 included in the warning. By comparing the current time with the drop-off time 102a2 output in the warning, the administrator may notice some abnormality, such as a child forgetting to get off the bus due to a significant delay in the shuttle bus service.

[0091] The entrance / exit management system 200 according to the second embodiment issues a warning when the shuttle bus 50 departs from a stop along the way, rather than when the measurement is completed. This allows the manager to check at each stop whether there are any children who have forgotten to get off or who have gotten off by mistake.

[0092] Third embodiment 7 shows the third embodiment. As shown in Fig. 7, this entrance / exit management system 300 is similar to the entrance / exit management system 100 of the first embodiment, except that one weight measuring device 20b is arranged at the boarding / exiting entrance of the shuttle bus 50.

The information processing device 10 determines that the measurement ends when the train ends its operation and enters the depot. The information processing device 10 can issue a warning if the total weight is equal to or greater than a preset weight when the measurement ends. The manager can confirm that there are passengers boarding and alighting on the train.

[0097] (2) A weight measuring device 20a is installed at the entrance of a hotel guest room and transmits the weight of the guest to the information processing device 10, which manages the weight of the guest in the guest room. The information processing device 10 considers the time when the guest finishes checking out to be the end of measurement. The information processing device 10 can issue a warning if the total weight is equal to or exceeds a preset weight when measurement is finished. The manager can confirm that the guest is in the guest room.

[0098] (3) Weight measuring devices 20a are installed at the trailhead and the trailhead, and transmit the weight of the climber to the information processing device 10, which manages the climber's weight. The information processing device 10 determines that the measurement ends when the climber completes his or her descent (e.g. 19:00). When the measurement ends, the information processing device 10 can issue a warning if the total weight is equal to or exceeds a preset weight. The administrator can confirm that the climber is present on the trail.

[0099] (4) A weight measuring device 20a is installed at the entrance to the cage of each animal in the zoo, and transmits the weight of the animals entering and leaving the cage to the information processing device 10, which manages the weight of the animals in the cage. The information processing device 10 determines that the measurement is finished when the cleaner starts cleaning the cage. The information processing device 10 can issue a warning if the total weight is equal to or greater than a preset weight when the measurement is finished. The manager can confirm that there is an animal in the cage.

[0100] (5) A weight measuring device 20a is installed at the entrance of the parking lot and transmits the weight of cars entering and exiting to the information processing device 10, which manages the weight of cars in the parking lot. The information processing device 10 considers the closing time of the parking lot to be the end of measurement. The information processing device 10 can issue a warning if the total weight is equal to or exceeds a preset weight when the measurement ends. The manager can confirm that cars are still remaining in the parking lot.

[0101] (6) For example, a weight measuring device 20a is installed at the entrance of a sealed tank for gas, oil, etc., and transmits the weight of an inspector entering or exiting the sealed tank to the information processing device 10, which manages the weight of the inspector inside the sealed tank. The information processing device 10 determines the end of the inspection as the end of measurement. The information processing device 10 can issue a warning if the total weight is equal to or greater than a preset weight when the measurement is completed. The manager can confirm that an inspector remains in the tank.

[0102] (7) A weight measuring device 20a is installed in front of a VIP room where high-ranking government officials and VIPs enter and exit, and transmits the weight of the high-ranking government officials and VIPs entering and exiting the VIP room to the information processing device 10, which manages the weight of the high-ranking government officials and VIPs in the VIP room. The information processing device 10 considers the end of the inspection to be the end of the measurement. The information processing device 10 can issue a warning if the total weight is equal to or greater than a preset weight when the measurement is completed. The manager can confirm that dangerous objects remain in front of the VIP room. [Explanation of symbols]
