Description

Technical Field

[0001] The present invention relates to a system for confirming the exit of incoming and outgoing items that have entered an entrance / exit location, and is used, for example, to confirm the disembarkation of children who have boarded a pick-up and drop-off bus at a kindergarten or nursery school.

Background Art

[0002] Recently, there have frequently been fatal accidents where children in kindergartens or nursery schools have been left trapped inside pick-up and drop-off buses for long periods due to the driver's oversight, resulting in heatstroke or the like.

[0003] Therefore, in order to prevent such accidents, a system that can prevent confinement inside the vehicle is desired.

[0004] For example, there has already been proposed a technique that can count the number of people passing through by detecting stepping on a detection mat provided at the entrance / exit of each floor in a building, and can total the number of people staying on each floor, such as a floor where people enter and exit (see Patent Document 1).

[0005] However, in the case of the above technique, there is a problem that it is difficult to count the number of people when multiple people enter and exit simultaneously.

[0006] On the other hand, there has also been proposed a system that measures the change in weight inside the elevator car when it stops at each floor, and assumes that the amount by which the weight inside the elevator car has decreased is the number of people who have entered that floor, and the amount by which the weight inside the elevator car has increased is the number of people who have exited that floor, and calculates the number of people entering and exiting each floor from the weight change and the average body weight to estimate the number of occupants on each floor (see Patent Document 2).

[0007]

Patent Document 1

[0008] However, the system described in Patent Document 2 involves attaching a weight measuring device to the elevator car and managing the total weight of the people inside the car to track increases and decreases in weight. This results in a large-scale weight measuring device, which poses a problem as it requires extensive renovation work to modify existing elevators, making it too costly.

[0009] This invention has been made in view of the above-mentioned problems, and aims to provide an entry / exit management system that allows administrators to quickly identify and address situations where the number of people entering an entry / exit location exceeds the set number of remaining entries at the end of the measurement period, without requiring extensive modifications to existing equipment. [Means for solving the problem]

[0010] To achieve the above objective, the entry and exit management system of the present invention is an entry and exit management system for managing the amount of goods entering and leaving an entry and exit location, wherein a weight measuring device is installed at the entrance and exit of the entry and exit location, and the weight of each item entering and leaving the entrance and exit is measured, while determining the entry and exit category, which indicates whether it is entering the entry and exit location or leaving the entry and exit location, and the total weight of the goods entering and leaving the entry and exit location is measured continuously from the start to the end of the measurement using the entry and exit category, and a warning is issued when the total weight of the goods entering and leaving at the end of the measurement exceeds a predetermined weight.

[0011] In the access control system of the present invention, examples of access locations include automobiles, including shuttle buses on which passengers get on and off, gymnasiums, concert halls, warehouses, and the like.

[0012] In the entry / exit management system of the present invention, examples of items entering or leaving the system include people and goods.

[0013] In the entry / exit management system of the present invention, the end of measurement can be defined as, for example, when the entry / exit location is a shuttle bus, the time when it arrives at the final stop and all passengers have disembarked.

[0014] The entry and exit management system of the present invention is preferably used in shuttle buses that transport kindergarten children, nursery school children, people attending welfare facilities, and people attending nursing care facilities. In other words, if passengers such as kindergarten children, nursery school children, children attending care facilities, or nursing care facilities who have difficulty disembarking on their own are left behind on the shuttle bus, the administrator (for example, the driver or the principal) can quickly notice this and prevent so-called "abandonment accidents."

[0015] In the entry / exit management system of the present invention, if the entry / exit location is a shuttle bus, it is preferable that the weight measuring device be installed on the step of the shuttle bus.

[0016] In other words, by installing 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, if a weight measuring device is provided in the above steps, it is even more preferable to provide a weight measuring device in two or more steps of any multiple steps.

[0018] In other words, by doing as described above, it is possible to determine whether a passenger is boarding or alighting based on the order in which they step on the weight measuring device. Furthermore, the entry and exit management system of the present invention may be configured such that, if a shuttle bus has multiple stops between the start and end of measurement, a warning is issued at each stop if the total weight of passengers after disembarking is outside a predetermined threshold of the total weight at the time of departure from that stop. In other words, by doing so, incorrect boarding and alighting procedures at each stop can be quickly identified, enabling safer transportation services.

[0019] The weight measuring device is not particularly limited. For example, there is an air mat device with a body weight measuring function described in JP-A-2018-29877. That is, when stepping on the mat, a metal inside the device bends, and the resistance value of a "strain gauge" stretched over the metal changes, and the body weight is measured using this principle. Not limited to the method using a "strain gauge", there are devices that have a mechanism for measuring body weight from the pressure applied to the liquid filled inside the device when stepping on the mat with the foot. As disclosed in https: / / www.amazon.co.jp / 体重計-インスマート-体脂肪計·体組成計-スマホ連動-FG260 / dp / B082SQX6TD?th=1, a weighing scale having a communication function with a smartphone or the like can also be used.

Advantages of the Invention

[0020] As described above, the entry / exit management system of the present invention is a management system for managing the amount of entry / exit of entry / exit items to / from the entry / exit location where the entry / exit items enter and exit. A weight measuring device is provided at the entrance / exit of the entry / exit location to measure the weight of each entry / exit item entering and exiting the entrance / exit, while measuring the total weight of the entry / exit items present in the entry / exit location at any time from the start of measurement to the end of measurement. When the total weight of the entry / exit items at the end of measurement is greater than or equal to a preset weight, a warning is issued. Therefore, the administrator of the entry / exit location can minimize the risk of overlooking the fact that the situation of the entry / exit items entering the location has become an abnormal situation. Moreover, since it is only necessary to provide a weight measuring device at the entrance / exit, an existing device can be easily modified.

Mode for Carrying Out the Invention

[0022] Hereinafter, embodiments 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 embodiments, and appropriate changes can be made without departing from the gist of the present invention.

[0023] (First Embodiment) The entry / exit management system 100 according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 6.

[0024] As will be described in detail below, this entry / exit management system 100 manages the entry / exit to / from the shuttle bus 50 as the entry / exit location, that is, the boarding and alighting (the entry amount of the incoming object) of the kindergarten children K such as kindergarten, nursery school, or children's garden (hereinafter only referred to as "garden") as passengers, and prevents overloading as follows.

[0025] The entry / exit management system 100 includes an information processing device 10, three weighing devices 20a, and two portable terminals 30a and 30b.

[0026] The information processing device 10 is communicable with the weighing device 20a and the portable terminals 30a and 30b via a communication line 40, and manages the boarding and alighting state of the kindergarten children K with respect to the shuttle bus 50 using the weight measured by the weighing device 20a.

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

[0028] The measuring unit 201 is designed to measure the weight of child K as they step on the steps when getting on or off the vehicle.

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

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

[0031] The mobile terminals 30a and 30b are configured to display a warning on their screens when the information processing device 10 determines that there is an abnormality.

[0032] Furthermore, of the two mobile terminals 30a and 30b, one mobile terminal 30a is to be held by the driver or placed in a location where the driver can immediately see the above warning, and the other mobile terminal 30b is to be held by the person in charge of transportation management on that day (which may be the head of the nursery) or placed in a location where the above warning can immediately see.

[0033] Furthermore, 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 decision information acquisition unit 1012 of the information processing device 10. In other words, 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 the warnings output from the information processing device 10, as described below (see Figure 4(a)).

[0035] Furthermore, when measurement begins, the mobile terminal 30a displays a "Childcare worker boarding complete" button 301 (see Figure 4(b)) on its screen, and when the "Childcare worker boarding complete" button 301 is pressed, it transmits that information to the information processing device 10.

[0036] Furthermore, as shown in Figure 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 is configured to receive the weight of the child K transmitted from the weight measuring device 20a.

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

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

[0040] When the weight receiving unit 1011 receives the weight information of child K, it also receives an identifier to identify the weight measuring device 20a in order to distinguish whether child K is getting on or off the shuttle bus 50.

[0041] The decision information acquisition unit 1012 acquires location information of the mobile terminal 30a and uses it as location information of the shuttle bus 50, and also acquires information on whether or not the childcare worker boarding completion button 301 provided on the mobile terminal 30a has been pressed.

[0042] The memory unit 102 is configured to temporarily store the total weight, the information received by the weight receiving unit 1011, and the information acquired by the judgment information acquisition unit 1012 as needed.

[0043] The processing unit 103 is configured to add and subtract the received weights to measure the total weight of the children K inside the shuttle bus 50.

[0044] In other words, the processing unit 103 includes a boarding / alighting determination unit 1031, a total weight measurement unit 1032, a determination unit 1033, and a warning generation unit 1034.

[0045] The boarding / alighting determination unit 1031 uses the identifiers of the three weight measuring devices 20a received from the transmission unit 202 of each weight measuring device 20a to determine whether a passenger is boarding or alighting.

[0046] In other words, when the identifiers of the lower weight measuring device 20a are received in that order, it is determined that the passenger has boarded the vehicle, and when the identifiers of the upper weight measuring device 20a are received in that order, it is determined that the passenger has disembarked, thereby enabling the determination of whether the passenger has entered or exited the vehicle.

[0047] The total weight measurement unit 1032 adds the weight of child K to the total weight if the boarding / alighting determination unit 1031 determines that the child is "boarding," and subtracts the weight of child K from the total weight if the child is "alighting," and updates the total weight in the memory unit 102 as needed.

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

[0049] Furthermore, the total weight measurement unit 1032 measures the total weight continuously from the start of measurement to the end of measurement. The total weight measurement unit 1032 measures the total weight each time the weight receiving unit 1011 receives the weight of child K (continuously).

[0050] The total weight measurement unit 1032 determines that measurement has started when the judgment information acquisition unit 1012 acquires that the childcare worker boarding completion button 301 has been pressed on the mobile terminal 30a, and measures the total weight using the weight received after the determination that measurement has started. In other words, even if a caregiver repeatedly gets on and off the shuttle bus 50 at a bus stop to allow child K to board and alight, their weight cancels out. Therefore, by determining the start of the measurement as described above, only child K's weight will be measured as the total weight.

[0051] Furthermore, the total weight measurement unit 1032 determines that the measurement has ended when the position information of the weight measuring device 20a, acquired by the judgment information acquisition unit 1012, is the position information of "the position where the shuttle bus 50 ends its shuttle service," and a predetermined time has elapsed since the acquisition of that position information.

[0052] Here, "the location where the shuttle bus 50 ends its service" refers to the place where the shuttle bus 50 ends its service (a bus stop where all children disembark, the drop-off location at the kindergarten, or the kindergarten's bus parking lot), and the predetermined time is, for example, 2 minutes. Both are stored in the memory unit 102 and can be set.

[0053] The determination unit 1033 is configured to determine that a warning should be issued if 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 measurement unit 1032 determines that the measurement has ended. Although the preset weight is zero, the preset weight may be 5 kg, as errors may occur in the weight measured by the weight measuring device 20a.

[0055] The warning generation unit 1034 refers to the total weight stored in the memory unit 102 and a preset weight to generate a warning that reads, "The total weight is __ kg, and the preset weight is __ kg. There is a risk that a child has been left unattended in the school bus. Please check."

[0056] The output unit 104 outputs the above warning to the screens of the mobile terminals 30a and 30b via the communication line 40 (see Figure 4).

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

[0058] Furthermore, the output unit 104 continues to output the warning until it receives input from the mobile terminals 30a and 30b indicating that the warning has been acknowledged. This minimizes the possibility of administrators overlooking or missing warnings.

[0059] The output unit 104 can not only display information on the screens of the mobile terminals 30a and 30b, but can also output audio. By outputting audio, the output unit 104 can ensure that drivers who are unable to see the system while driving can still recognize the warning.

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

[0061] Next, the management operation of the access control system 100 will be explained using the processing flow of the information processing device 10 (see Figure 3).

[0062] (Step 1) When child K boards or alights from the shuttle bus 50, child K steps on the weight measuring device 20a located on the step. When the weight measuring device 20a is stepped on, the measuring unit 201 measures child K's weight. The transmitting unit 202 transmits the weight along with 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 weight and the identifier of the weight measuring device 20a consecutively from the three weight measuring devices 20a and temporarily stores them in the storage unit 102.

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

[0064] (Step 3) The decision information acquisition unit 1012 acquires decision information from the mobile terminal 30a to determine the start and end of the total weight measurement.

[0065] (Step 4) The total weight measurement unit 1032 determines whether it is the start or 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 measurement unit 1032 resets the total weight stored in the memory unit 102. The total weight measurement unit 1032 measures the total weight based on the weight received from the weight measuring device 20a and the boarding / alighting classification determined by the boarding / alighting judgment unit 1031. The total weight measurement unit 1032 adds to the total weight if boarding occurs and subtracts from the total weight if alighting occurs.

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

[0067] If it is determined that no warning should be issued (NO in S5), the process will terminate. If it is determined that a warning should be issued (YES in S5), the next step will be performed.

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

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

[0070] As described above, this entry / exit management system 100 continuously measures the total weight of the child K riding in the shuttle bus 50 from the start to the end of the measurement, and issues a warning if the total weight of the child K at the end of the measurement exceeds a predetermined weight. This reduces the risk for the administrator of overlooking the situation in which the child K has been left behind in the shuttle bus 50.

[0071] Furthermore, since a commercially available weighing scale with communication capabilities with the aforementioned smartphone can be used as the weight measuring device 20a, the system can be built inexpensively without extensively modifying the shuttle bus 50.

[0072] Furthermore, since the weight measuring device 20a is detachable, a malfunctioning weight measuring device 20a can be immediately replaced. Therefore, the system offers high robustness as an access control system.

[0073] (Modification of the first embodiment)

[0074] In the first embodiment of the access control system 100, the information processing device 10 acquires location information of the shuttle bus 50 using the GPS function of the mobile terminal 30a, but it is not limited to this. For example, the shuttle bus may be equipped with a GPS function, or one of the weight measuring devices 20 may be equipped with a GPS function.

[0075] In the first embodiment, the weight measuring devices 20a of the access control system 100 were installed on each of the three steps of the shuttle bus 50, and all weight measuring devices 20a transmitted weight to the information processing device 10, but this is not limited to this. The weight measuring devices 20a may be installed on any two of the three steps of the shuttle bus 50, and dummy mats may be placed on the other steps. By using two weight measuring devices 20a, the access control system 100 can be provided at a low cost.

[0076] The access control system 100 according to the first embodiment was equipped with three weight measuring devices 20a having the same function at each step, but is not limited to this. For example, the weight measuring device 20a could be placed at only one step, and mats that can transmit only an identifier when stepped on could be placed at the other steps. In this way, only one weight measuring device 20a with complex functions is required, so the access control system 100 can be constructed at a low cost.

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

[0078] In the access control system 100 according to the first embodiment, communication between the three weight measuring devices 20a, the two mobile terminals 30, and the information processing device 10 is performed via a communication line 40, but this is not limited to that. Such communication may also be performed using short-range wireless communication. In this way, regardless of communication failures or delays in the communication line 40, the information processing device 10 can receive weight from the weight measuring devices 20a and issue a warning to the mobile terminals 30.

[0079] In the entry / exit management system 100 according to the first embodiment, the warnings output to mobile terminals 30a and 30b were identical, but they may be different. The warning to mobile terminal 30b used by the principal may include a warning urging the principal to contact the driver, in addition to "There is a risk that a child has been left behind in the shuttle bus. Please check." This way, even if the driver overlooks it, the principal can contact the driver about the child being left behind.

[0080] In the entry / exit management system 100 according to the first embodiment, the warnings output to mobile terminals 30a and 30b were at the same time, but they may be at different times. If the confirmation button input on mobile terminal 30a is not confirmed even after a predetermined time has elapsed since the output unit 104 output a warning, a warning may be output to mobile terminal 30b. By warning the park director, it is possible to minimize the chances of the driver overlooking the warning.

[0081] (Second Embodiment) The entry / exit management system 200 of the second embodiment differs from the entry / exit management system 100 in that, while the entry / exit management system 100 used a determination unit 1033 to determine whether the total weight of the child K at the end of measurement was equal to or greater than a preset weight, the determination unit 1033 of the entry / exit management system 200 determines whether to issue a warning when the child has finished disembarking at each stop (or when departing from the stop), as described below. The entry / exit management system 200 will be described below, focusing on the differences.

[0082] In other words, the entry / exit management system 200 is configured such that the storage unit 102 stores the weight data 102a after disembarking (see Figure 6).

[0083] The shuttle bus 50 has two routes: (1) a drop-off route (picking up child K at the kindergarten, dropping them off at a bus stop, and returning to the kindergarten) and (2) a pick-up route (departing from the kindergarten, picking up child K at a bus stop, returning to the kindergarten, and dropping off child K). The above post-drop-off weight data 102a is data on the total weight inside the shuttle bus 50 after child K has dropped off at each bus stop on the (1) drop-off route.

[0084] Furthermore, the post-disembarkation weight data 102a consists of data for each bus stop, including bus stop location information 102a1, disembarkation time 102a2, total weight at departure from the bus stop 102a3, and information on the children who disembarked 102a4, and is pre-prepared data.

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

[0086] In this entry / exit management system 200, the determination unit 1033 compares the total weight of the children K after disembarking with the total weight 102a3 at the time of departure from the bus stop to determine whether the difference is outside the threshold.

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

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

[0089] (When the total weight of child K after disembarking - total weight 102a3 at departure from the bus stop) > threshold The warning generation unit 1034 refers to the disembarking child information 102a4 and generates the following warning: "The current total weight of children on the shuttle bus 50 is __ kg, and the estimated weight when departing this stop is __ kg. There may be children who have forgotten to disembark. Please check. The children disembarking at this stop are Jiro Toshio and Hanako Isho." (When the total weight at departure from the bus stop (102a3) - the total weight of the child K after disembarking) > threshold The warning generation unit 1034 refers to the disembarking child information 102a4 and generates the following warning: "The current total weight of children on the shuttle bus 50 is __ kg, and the estimated weight when departing this stop is __ kg. There may be children who have disembarked by mistake. Please check. The children disembarking at this stop are Jiro Toshio and Hanako Isho."

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

[0091] The entry / exit management system 200 according to the second embodiment is configured to issue a warning not at the end of measurement, but when the shuttle bus 50 departs from an intermediate stop. This allows the administrator to confirm at each stop whether there are children who have forgotten to get off or who have gotten off by mistake.

[0092] (Third embodiment) Figure 7 shows a third embodiment. As shown in Figure 7, this access control system 300 is the same as the access control system 100 of the first embodiment, except that one weight measuring device 20b is placed at the entrance / exit of the shuttle bus 50.

[0093] In other words, the weight measuring device 20b is equipped with a total of N × M piezoelectric elements 204, N in the vertical direction and M in the horizontal direction, so that the boarding / alighting determination unit of the weight measuring device 20b can determine whether it is boarding or alighting based on the order in which the piezoelectric elements 204 are stepped on. Furthermore, such a weight measuring device 20b can be made by applying publicly known technology (e.g., Japanese Patent Application Publication No. 2020-230443).

[0094] The entry and exit management system 300 according to the third embodiment uses a single weight measuring device 20b to determine whether a child has boarded or disembarked, as described above. Therefore, it can be used even in small shuttle buses 50 with narrow entrances or no steps, and the costs required for weight measuring devices can be reduced.

[0095] (Other variations) The entry and exit management system 100 of the present invention can be used not only to manage the boarding and alighting of children K onto the shuttle bus 50, but also to avoid the risk of administrators overlooking congestion, for example, in the following types of entry and exit management systems.

[0096] (1) A weight measuring device 20a is installed at the entrance of each train car and transmits the weight of passengers getting on and off to an information processing device 10, which manages the weight of passengers getting on and off the train. The information processing device 10 considers the measurement to end when the train finishes operation and enters the depot. At the end of the measurement, the information processing device 10 can issue a warning if the total weight is greater than or equal to a preset weight. The administrator can confirm that there are passengers getting on and off the train.

[0097] (2) A weight measuring device 20a is installed at the entrance of each hotel room and transmits the guest's weight to the information processing device 10, which manages the weight of guests in the rooms. The information processing device 10 considers the measurement to end when the guest checks out. The information processing device 10 can issue a warning if the total weight at the end of the measurement exceeds a preset weight. The manager can confirm that there is a guest in the room.

[0098] (3) A weight measuring device 20a is installed at the trailhead and the exit point of the mountain climber, and transmits the weight of the climber to the information processing device 10, which manages the weight of the climber. The information processing device 10 considers the measurement to end when the climber completes their descent (e.g., 19:00). At the end of the measurement, the information processing device 10 can issue a warning if the total weight exceeds a preset weight. The administrator can confirm the presence of climbers on the mountain.

[0099] (4) A weight measuring device 20a is installed at the entrance of each animal enclosure in the zoo, and transmits the weight of the animals entering and leaving the enclosure to the information processing device 10, which manages the weight of the animals inside the enclosure. The information processing device 10 considers the measurement to end when the cleaning staff begins cleaning the enclosure. The information processing device 10 can issue a warning if the total weight at the end of the measurement exceeds a preset weight. The manager can then confirm that there are animals inside the enclosure.

[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 end of measurement to be the closing time of the parking lot. At the end of measurement, the information processing device 10 can issue a warning if the total weight is above a preset weight. The manager can confirm that there are cars remaining in the parking lot.

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

[0102] (7) A weight measuring device 20a is installed in front of the VIP room used by government officials and dignitaries, and transmits the weight of government officials and dignitaries entering and leaving the VIP room to the information processing device 10, which manages the weight of government officials and dignitaries in the VIP room. The information processing device 10 considers the end of measurement to be the end of inspection. The information processing device 10 can issue a warning if the total weight at the end of measurement is greater than or equal to a preset weight. The administrator can confirm whether any hazardous materials remain in front of the VIP room. [Explanation of Symbols]
