Note that the present invention is not limited to the embodiments.

[overall structure]
FIG. 1 is an explanatory diagram illustrating an example of an environment information acquisition system according to an embodiment. In FIG. 1, the environment information acquisition system includes a beacon device 10, a measurement device 20, a management server 30, and a guardian terminal 40. In addition, in order to simplify description here, the case where the beacon apparatus 10, the measuring apparatus 20, the management server 30, and the guardian terminal 40 are each one is demonstrated as an example.

  The beacon device 10 is an example of a terminal that transmits a beacon signal. The measuring device 20 is an example of a terminal that measures environmental information. The management server 30 is an example of a server that manages measurement results. The guardian terminal 40 is an example of a terminal that acquires measurement results.

  The beacon device 10 in the present embodiment is an example of a device that is possessed by a guardian such as a child or an elderly person and that transmits a radio signal regularly or at an arbitrary timing. In the present embodiment, as an example of a radio signal, a beacon signal including information for uniquely identifying a person to be protected such as a person to be protected ID is used.

  The beacon device 10 is a device that can communicate within a range of several meters to 10 meters, for example, Bluetooth (registered trademark) LE. The beacon device 10 may be used also as a mobile terminal such as a mobile phone or a smartphone, or may be a dedicated terminal having only a function of transmitting a beacon signal.

  In the example of FIG. 1, the beacon device 10 moves along with the protected person as indicated by a dashed arrow. The communication area 10a indicates a communication range of a beacon signal transmitted by the beacon device 10 after the protected person moves along the dashed arrow.

  In such a state, when the measurement apparatus 20 in the present embodiment receives identification information for identifying the first terminal 10 from the first terminal 10, a communication unit that transmits the identification information to the management server 30. And a measurement unit that measures environmental information specified by the measurement request and transmits it to the management server 30 when a measurement request for environmental information is received from the management server 30 that has received the identification information.

  In addition, the management server 30 in the present embodiment receives the identification information from the measurement device 20 and the storage unit that stores the identification information for identifying the first terminal 10 and the type of the environmental information that is the measurement target in association with each other. In this case, a request unit that transmits a measurement request for the type of environmental information associated with the identification information to the measurement device 20, and a provision unit that provides the measurement result received from the measurement device 20 to the second terminal.

  In other words, the measuring device 20 that has received the beacon signal from the beacon device 10 of the protected person measures the environmental data around the protected person instructed by the management server 30 and transmits it to the management server 30. The management server 30 that has received the environmental data provides the guardian's terminal 40 with the environmental data, so that the guardian's environmental information can be provided to the guardian.

  The guardian terminal 40 in the present embodiment is an example of a terminal that receives measurement results from the management server 30 with an arbitrary method and timing. The guardian terminal 40 may be either a portable terminal or a stationary terminal, and is connected to the management server 30 via a network.

[Configuration of measuring device]
Next, the function of each operation subject in the embodiment will be described. FIG. 2 is a functional block diagram illustrating an example of the measurement apparatus according to the embodiment. In FIG. 2, the measurement apparatus 20 includes a signal reception unit 201, a communication unit 202, a control unit 203, a storage unit 204, an operation unit 211, and a display unit 212.

  The signal receiving unit 201 is a processing unit that receives a beacon signal transmitted from the beacon device 10 and outputs the protected person ID included in the beacon signal to the control unit 203. The communication unit 202 is a processing unit that communicates with, for example, the management server 30 via a network. Communication with the network is realized by a mobile communication method such as LTE (Long Term Evolution), but may be realized by a wired connection such as a general telephone line. The communication unit 202 is an example of a transmission unit.

  The storage unit 204 stores information such as a measurement device ID that uniquely identifies the measurement device 20. The operation unit 211 is a processing unit that receives various operations from the operator of the measurement apparatus 20. The operation unit 211 is realized by, for example, a keyboard or a button as an input device. The operation unit 211 outputs an operation input by the operator to the control unit 203 as operation information. Note that the operation unit 211 may be realized by a touch panel or the like as an input device, and the display device of the display unit 212 and the input device of the operation unit 211 may be integrated.

  The display unit 212 is a processing unit that displays various types of information. The display unit 212 is realized by, for example, a liquid crystal display as a display device. The display unit 212 displays various screens such as measurement values acquired by the result acquisition unit 221, for example.

  Next, each functional block of the control unit 203 will be described. As illustrated in FIG. 2, the control unit 203 includes a result acquisition unit 221, an information generation unit 222, and a situation acquisition unit 223.

  The result acquisition unit 221 is a processing unit that receives an instruction from the information generation unit 222, acquires measurement values from various sensors included in the measurement device 20, and outputs the measurement values to the information generation unit 222. For example, when the result acquisition unit 221 receives an instruction to acquire the measurement value of “air temperature” from the information generation unit 222, the result acquisition unit 221 instructs the thermometer of the measurement device 20 to acquire the measurement value, and the information generation unit It outputs to 222. In the present embodiment, the position information is also included in the environmental information, and the result acquisition unit 221 acquires the position information as a measurement value.

  The information generation unit 222 is a processing unit that transmits a message to the management server 30 through the communication unit 202. Specifically, when receiving the input of the guardian ID from the signal reception unit 201, the information generation unit 222 reads the measurement device ID from the storage unit 204 and generates a message to be transmitted to the management server 30. For example, the information generation unit 222 generates a message including the protected person ID “000000” received from the beacon device 10 and the measurement device ID “200000” read from the storage unit 204, and transmits the message to the management server 30. .

  Further, when the information generation unit 222 receives a measurement request from the management server 30 through the communication unit 202, the information generation unit 222 instructs the result acquisition unit 221 to acquire a measurement value according to the measurement request. FIG. 3 is an explanatory diagram illustrating an example of a data structure of a measurement request according to the embodiment. In FIG. 3, the guardian ID and the measurement device ID are the same as those included in the message transmitted from the information generation unit 222 to the management server 30. The required items and measurement conditions include items and conditions specified in the processing in the management server 30 described later. In the example of FIG. 3, the required items include “PM2.5”, “temperature”, and “humidity”, and further include measurement conditions for “temperature” and “humidity”, respectively.

  The measurement conditions are conditions for the measurement apparatus 20 to measure environmental information. When the measurement request received from the management server 30 includes the measurement condition, the information generation unit 222 instructs the status acquisition unit 223 to acquire information regarding the measurement condition, and only when the acquired information satisfies the measurement condition. The result acquisition unit 221 is instructed to acquire the measurement value. The processing of the status acquisition unit 223 will be described later. On the other hand, when the measurement request does not include the measurement condition, the information generation unit 222 instructs the result acquisition unit 221 to acquire the measurement value without instructing the situation acquisition unit 223 to acquire information.

  As shown in FIG. 3, the measuring device 20 measures “air temperature” only when “the current time is between 11:00 and 16:00”, and “the remaining battery level of the measuring device 20 is 50% or more”. Only measure “humidity”. If the measurement condition is not included, the “measurement condition” column is “N / A”.

  In the example of FIG. 3, the information generation unit 222 instructs the status acquisition unit 223 to acquire the current time for the temperature measurement condition and to acquire the remaining battery level for the humidity measurement condition. For example, when the remaining battery level acquired from the status acquisition unit 223 is “40%”, the information measurement unit 222 does not instruct the result acquisition unit 221 to measure humidity because the humidity measurement condition is not satisfied.

  Further, when receiving the input of the measurement value from the result acquisition unit 221, the information generation unit 222 transmits the measurement result including the measurement value to the management server 30 through the communication unit 202. FIG. 4 is an explanatory diagram illustrating an example of a data structure of measurement results according to the embodiment. As shown in FIG. 4, the measurement result includes a guardian ID, a measurement device ID, a measurement date and time when the measurement value is acquired, and a measurement value of each request item. In FIG. 4, the guardian ID and the measurement device ID are the same as those included in the measurement request shown in FIG. “Condition nonconformity” in the column of “Required item 3” indicates that the measurement condition of the humidity is not satisfied in the measurement apparatus 20, as described above. If the measurement date / time varies depending on the request item, the measurement date / time may be transmitted for each request item. The result acquisition unit 221, the information generation unit 222, and the communication unit 202 are examples of a measurement unit.

  The status acquisition unit 223 is a processing unit that receives an instruction from the information generation unit 222, acquires information regarding measurement conditions such as the current time and the remaining battery level, and outputs the information to the information generation unit 222. For example, when the status acquisition unit 223 receives an instruction from the information generation unit 222 to acquire information on the measurement conditions, the status acquisition unit 223 refers to a clock or a battery fuel gauge that the measurement device 20 has, such as the current time and the battery remaining amount. Information on measurement conditions is acquired and output to the information generation unit 222.

[Management server configuration]
FIG. 5 is a functional block diagram illustrating an example of the management server according to the embodiment. In FIG. 5, the management server 30 includes a communication unit 301, a control unit 302, a storage unit 303, an operation unit 304, and a display unit 305.

  The communication unit 301 is a processing unit that performs communication between the measurement device 20 and the guardian terminal 40 via a network. The operation unit 304 is a processing unit that accepts various operations from an administrator or the like. The operation unit 304 is realized by, for example, a keyboard or a mouse as an input device. The operation unit 304 outputs an operation input by the administrator to the control unit 302 as operation information. The operation unit 304 may be implemented as a touch panel or the like as an input device, and the display device of the display unit 305 and the input device of the operation unit 304 may be integrated.

  The display unit 305 is a processing unit that displays various types of information. The display unit 305 is realized by, for example, a liquid crystal display as a display device. The display unit 305 displays various screens such as a measurement device DB.

  Next, the DB stored in the storage unit 303 will be described. The storage unit 303 includes a guardian DB 321, a measurement device DB 322, and a guardian DB 323. The contents of each DB are updated as appropriate by the processing of the information update unit 315 described later.

  The protected person DB 321 stores information on a protected person to be monitored by the guardian. FIG. 6 is a diagram illustrating an example of the guardian DB according to the embodiment. The protected person DB 321 includes “protected person ID”, “protected person name”, “attribute”, “guardian ID”, “request item 1”, “request item 2”, “request item 3”, “notification”. “Request” and “Point to be granted” are stored in association with each other. In FIG. 6, one row corresponds to one protected person. The protected person DB 321 is an example of a target storage unit.

  “Protected person name” and “attribute” are information indicating the name and attribute of the protected person specified by the protected person ID, respectively. “Guardian ID” is information that uniquely identifies a guardian who monitors the person to be protected. It may be configured such that one guardian requests monitoring of a plurality of guardians, such as guardian IDs “000001” and “000004”.

  "Request item 1, request item 2, request item 3" is information indicating which measurement value is requested to be acquired for the protected person. For example, for a guardian whose guardian ID is “000000”, acquisition of three types of measurement values “PM2.5”, “temperature”, and “humidity” is required.

  The “notification request” is information indicating whether or not to acquire a measured value of environmental information for the protected person and notify the guardian. For example, when the notification request is “present”, the measurement value is acquired and notified to the guardian by a method designated by the guardian. When “not present”, the measurement request is sent to the measuring device 20. Does not transmit and does not acquire measurement values.

  The protected person DB 321 may not include the “notification request” column. In this case, the management server that has received the guardian ID from the measurement device 20 always transmits a measurement request to the measurement device 20.

  “Points to be given” indicates points given to the measuring device 20 when the measured value of the environmental information related to the protected person is acquired. The points are used, for example, to give incentives to the owner of the measuring device 20 such that the usage fee of the measuring device 20 is discounted or money is given according to the given points. The process of giving points will be described later.

  Next, the measurement apparatus DB 322 will be described. The measuring device DB 322 stores information on measuring devices that measure environmental information. FIG. 7 is a diagram illustrating an example of the measurement apparatus DB according to the embodiment. The measurement apparatus DB 322 stores “measurement apparatus ID”, “upper limit measurement count”, “measurement count within a period”, “point”, and a plurality of pieces of environment information in association with each other. In FIG. 7, one row corresponds to one measuring device. The measurement device DB 322 is an example of a device storage unit.

  In the example of FIG. 7, the measurement apparatus DB 322 stores “PM2.5”, “temperature”, “humidity”, “atmospheric pressure”, and “current position / installation location” as environment information. In the present embodiment, it is assumed that the position information is also included in one of the environmental information, and whether or not the measurement result is requested can be specified. Moreover, the environment information shown in FIG. 7 is only an example, and may be configured to include other environment information that can be measured by the measurement apparatus 20, such as pollen concentration.

  In FIG. 7, the “upper limit measurement count” is the upper limit of the number of times that the measurement apparatus can measure within a predetermined period. For example, for the measuring device with the measuring device ID “200003”, the number of measurements per day is “2 times”.

  In FIG. 7, the column “Number of measurements within a period” stores how many times the measurement device has transmitted a measurement value to the management server within a predetermined period. The column “number of measurements within a period” stores “0” as an initial value, and is incremented by a process described later. Note that the value of “number of measurements within a period” is reset to “0” at a predetermined timing such as 0:00 every day. For example, it is registered that the measurement device whose measurement device ID is “20003” has been measured “twice”.

  In FIG. 7, the “point” column stores the total number of points given to the measurement apparatus. The “point” column in FIG. 7 is updated by processing of a point calculation unit 313 described later.

  In FIG. 7, “OK” in each environmental information column indicates that the measurement value of the environmental information is always permitted, and “NG” is provided with the sensor of the environmental information, but the measurement value is provided. Indicates that it is not allowed. Further, “-” indicates that the measuring apparatus is not equipped with a sensor for the environmental information.

  Note that “OK (with condition)” is a setting for permitting or disabling the provision according to the state of the measuring device 20 such as the remaining battery level and time of the measuring device 20. For example, the measuring device 20 with the measuring device ID “200000” provides the measured value of “air temperature” only when “the current time is between 11: 00 and 16:00”, and “the remaining battery level of the measuring device 20 is Provide a measurement of "humidity" only if it is "50% or more".

  For example, when the measuring device 20 is a stationary terminal, whether or not position measurement is possible or whether or not position information can be provided in the “current position / installation location” column, You may memorize | store the address, building name, etc. of the place where the said apparatus is deferred. An example of storing the address or building name of the place where the apparatus is deferred is shown in the column “Current position / installation location” of the measurement apparatus ID “20002” in FIG.

  Next, the guardian DB 323 will be described. The guardian DB 323 stores information on the guardian who monitors the guardian. FIG. 8 is a diagram illustrating an example of the guardian DB according to the embodiment. The guardian DB 323 stores “guardian ID”, “guardian name”, “notification timing”, “desired contact method”, and a plurality of contacts in association with each other. In the example of FIG. 8, a mail address, a telephone number, and a Push communication terminal ID are stored as contact information. In FIG. 8, one row corresponds to one guardian.

  In the guardian DB 323, “guardian name” is information indicating the name of the guardian identified by the guardian ID. “Notification timing” and “desired contact method” are information indicating a timing and a method in which the guardian desires to provide a measurement result.

  In the “notification timing” column of the parent DB 323, “as needed” means “designated time” is the time designated by the guardian every day immediately after obtaining the measurement result from the measuring device 20, and “regular” is every fixed time. Shows the measurement results for parents.

  Next, each functional block of the control unit 302 will be described. The control unit 302 includes a request generation unit 311, a notification generation unit 312, a point calculation unit 313, a result calculation unit 314, and an information update unit 315.

  The request generation unit 311 is a processing unit that generates a measurement request and transmits the measurement request to the measurement apparatus 20 through the communication unit 301. An example of the measurement request is as shown in FIG. The request generation unit 311 refers to the protected person DB 321 and the measuring apparatus DB 322, and extracts the protected person ID received from the measuring apparatus 20 and the environment information associated with the measuring apparatus ID. The communication unit 301 and the request generation unit 311 are an example of a request unit.

  For example, when the protected person ID received from the measuring apparatus 20 is “000000”, the request generation unit 311 refers to the row where the protected person ID of the protected person DB 321 illustrated in FIG. 6 is “000000”. The required items “PM2.5”, “temperature” and “humidity” are extracted.

  Next, the request generation unit 311 refers to the measurement device DB 322 illustrated in FIG. 7 and extracts environment information associated with the measurement device ID. For example, the request generation unit 311 includes request items “PM2.5”, “air temperature”, “humidity” corresponding to the measurement device ID “200000” received from the measurement device 20, and measurement conditions associated with the request items. To extract. In addition, in the measurement device ID, other required items such as “current position / installation location” also correspond to the measurement device ID “200000”, but in this embodiment, the protected person ID received from the measurement device 20 is used. Only request items corresponding to are extracted.

  When there is no target environment information or when the “notification request” column of the protected person DB 321 is “none”, the request generation unit 311 instructs the measurement apparatus 20 to “no corresponding information”. May be notified. 7, when the number of measurements within the period reaches the upper limit number of measurements, such as the measurement apparatus having the measurement apparatus ID “20002” in the example of FIG. It may be configured to notify “exceeding number of measurements”.

  The notification generation unit 312 is a processing unit that generates a result notification to be provided to the guardian and provides the result notification to the guardian terminal 40 through the communication unit 301. The communication unit 301 and the notification generation unit 312 are an example of a providing unit.

  For example, when the measurement result as illustrated in FIG. 4 is received from the measurement device 20, the notification generation unit 312 refers to the protected person DB 321 and refers to the protected person name and attribute associated with the protected person ID. The guardian ID and the request item are read out. In the present embodiment, the name of the guardian corresponding to the guardian ID “000000” “John”, the guardian ID “100000”, the requirement item 1 “PM2.5”, the requirement item 2 “temperature” and the requirement item 3 Read “humidity”. Further, the notification generation unit 312 refers to the guardian DB 323 and reads the guardian name “Aiden” corresponding to the guardian ID “100000”.

  Next, the notification generation unit 312 generates a result notification using information read from the protected person DB 321 and the guardian DB 323. FIG. 9 is an explanatory diagram illustrating an example of a data structure of a result notification according to the embodiment. As shown in FIG. 9, the result notification includes a guardian name, a guardian name, a guardian attribute, a measurement device ID, a measurement date and time, and a measurement value of environmental information requested by the guardian. The measurement value “N / A” indicates that the measurement value could not be acquired for the environmental information.

  Next, the notification generation unit 312 notifies the guardian through the communication unit 301 at the timing stored in the “notification timing” column of the parent DB 323 by the method stored in the “desired contact method” column. In this embodiment, as shown in the column of the guardian ID “100000” of the guardian DB 323 shown in FIG. 8, the notification generation unit 312 immediately receives the measurement result at the mail address “aaa@aaa.aa”. , Send a result notification.

  The point calculation unit 313 is a processing unit that calculates points to be given to the measurement apparatus with reference to the protected person DB 321 when the measurement result is acquired, and records the points in the measurement apparatus DB 322. The result calculation unit 314 is a processing unit that performs a processing process that calculates, for example, an average value of a plurality of measurement results or graphs the measurement results. Details of each process will be described later.

  The information update unit 315 updates the information stored in the protected person DB 321, the measurement device DB 322, and the guardian DB 323 based on an instruction received from the measurement device 20, the guardian terminal 40, or the operation unit 304 of the management server. It is a processing unit. The information update unit 315 adds information on a new person to be protected, a measurement device, and a guardian, and also, for example, gives an instruction to change the setting as to whether or not to allow the provision of measurement values from the user of the measurement device 20 In response, the measurement device DB 322 is updated. Specifically, the information update unit 315 updates each “request item” column of the measurement apparatus DB 322 to “OK” or “NG”, or sets or deletes the “measurement condition” in the “request item” column. To do.

[System Operation]
Next, by the environment information acquisition system according to the present embodiment, the measurement device 20 that has received the beacon signal from the beacon device 10, and the management server 30 that acquires the measurement result from the measurement device 20 and provides it to the guardian terminal 40. The processing operation to be linked will be described. FIG. 10 is a sequence diagram relating to environment information acquisition according to the embodiment. While moving with the owner, the beacon device 10 transmits a beacon signal including the guardian ID periodically or at an arbitrary timing. As a result of the movement of the beacon device 10, the measuring device 20 that has entered the communication range 10a receives a beacon signal from the beacon device 10 (step S101).

  The measuring device 20 transmits a message including the protected person ID and the measuring device ID to the management server 30 (step S102). The management server 30 that has received the message from the measurement device 20 transmits an environmental information measurement request to the measurement device 20 (step S103). The measuring device 20 measures the environmental information and transmits the measurement result to the management server 30 (step S104). The management server 30 that has received the measurement result provides the result notification to the guardian terminal 40 at the notification timing and desired contact method defined in the guardian DB 323 (step S105).

[Measurement device processing]
Next, the flow of processing of each operation subject in the environment information acquisition system according to the present embodiment will be described. FIG. 11 is a diagram illustrating an example of a processing flow of the measurement apparatus according to the embodiment.

  The signal receiving unit 201 receives a beacon signal from the beacon device 10 and outputs it to the information generating unit 222 (step S401). The information generation unit 222 reads the measurement device ID of the measurement device 20 from the storage unit 204, and transmits the protected person ID and the measurement device ID included in the received beacon signal to the management server 30 through the communication unit 202. (Step S402).

  When the information generation unit 222 receives a measurement request from the management server 30 through the communication unit 202 (step S403: Yes), the information generation unit 222 determines whether the received measurement request matches the measurement condition (step S404).

  For example, a case where a measurement request as shown in FIG. 3 is received will be described. The information generation unit 222 specifies that the current time is between “11:00 to 16:00” as a condition for measuring the “temperature” of the request item 2, so the status acquisition unit 223 indicates the current time. Instruct acquisition. The status acquisition unit 223 acquires the current time from, for example, a clock and provides the information generation unit 222 with the current time.

  For example, when the current time acquired from the status acquisition unit 223 is “2015/8/16 13:00:12”, the measurement condition set in the request item 2 is satisfied (step S404: Yes). In this case, the information generation unit 222 instructs the result acquisition unit 221 to acquire the measurement value of “air temperature” (step S405). The result acquisition unit 221 acquires, for example, the temperature measured by a thermometer and outputs the temperature to the information generation unit 222. The same applies to the case where the measurement condition is not defined, such as “PM2.5” of requirement item 1 shown in FIG.

  On the other hand, as shown in FIG. 3, the information generation unit 222 is designated as “50% or more” as the remaining battery level as a condition for measuring the “humidity” of the request item 3, and thus the status acquisition unit 223. To get the remaining battery power. The status acquisition unit 223 acquires the remaining battery level from, for example, the battery fuel gauge of the measuring device 20 and provides the information generation unit 222 with the remaining battery level.

  For example, when the remaining battery level acquired from the status acquisition unit 223 is “40%”, the measurement condition set in the request item 3 is not satisfied, so the information generation unit 222 causes the result acquisition unit 221 to measure “humidity”. The acquisition of the value is not instructed (step S404: No). Note that, as in the example illustrated in FIG. 3, when the measurement request includes a plurality of request items, the information generation unit 222 repeats the process of S404 for all the request items.

  Next, the information generation unit 222 transmits the acquired measurement result to the management server 30 (step S406). An example of the measurement result to be transmitted is as shown in FIG. In the present embodiment, even when the measurement values are not acquired for some or all of the request items of the measurement request, a response indicating that the measurement values are not acquired is transmitted to the management server 30.

  When no measurement request is received from the management server 30 (step S403: No), for example, when a notification of “no relevant information” is received from the management server 30, the measurement result is not transmitted to the management server 30, and the process is performed. finish.

[Management server processing]
Next, a processing flow of the management server according to the present embodiment will be described. FIG. 12 is a diagram illustrating an example of a processing flow of the management server according to the embodiment. The request generation unit 311 of the management server 30 receives a message including the protected person ID and the measurement device ID from the measurement device 20 through the communication unit 301 (step S601).

  The request generation unit 311 refers to the protected person DB 321 and acquires a request item corresponding to the received protected person ID (step S602). In addition, when the received protected person ID is not registered in the protected person DB 321 (step S603: No), the request generation unit 311 notifies the measuring apparatus 20 of “no corresponding data” through the communication unit 301, The process ends (step S621). The same applies when the request item corresponding to the protected person ID is not registered in the protected person DB 321.

  In the present embodiment, the request generation unit 311 acquires the request items “PM2.5”, “temperature”, and “humidity” corresponding to the received protected person ID “000000” (step S603: Yes).

  Next, the request generation unit 311 refers to the measurement device DB 322 and searches for the request item associated with the received measurement device ID from the acquired request items (step S604). If the received measurement device ID is not registered in the measurement device DB 321 (step S605: No), the request generation unit 311 notifies the measurement device 20 that there is no corresponding data through the communication unit 301 and ends the process. (Step S621). The same applies when the request item corresponding to the measurement device ID is not registered in the measurement device DB 321.

  In the present embodiment, the request generation unit 311 acquires the request items “PM2.5”, “temperature”, and “humidity” corresponding to the received measurement device ID “200000” among the acquired request items (step) S605: Yes). Further, the measurement conditions associated with the request items “temperature” and “humidity” are also acquired.

  Next, the request generation unit 311 refers to the measurement device DB 322 and determines whether the number of measurements in the measurement device 20 has reached the upper limit (step S606). If it is determined that the number of measurements in the measurement device 20 has reached the upper limit (step S606: No), the request generation unit 311 notifies the measurement device 20 of “exceeding the number of measurements” via the communication unit 301 and ends the process. (Step S622). In the measurement apparatus DB 322 illustrated in FIG. 7, for example, for the measurement apparatus 20 with the measurement apparatus ID “200003”, the upper limit measurement count is “2 times / day”, and the measurement count within the period is “2 times”. Therefore, the request generation unit 311 notifies the measurement device 20 of “excess of the number of measurements”.

  If it is determined that the number of measurements in the measurement apparatus 20 has not reached the upper limit (step S606: Yes), the request generation unit 311 generates a measurement request as shown in FIG. (Step S607).

  Next, the communication unit 301 waits for reception of a response from the measurement device 20. If no measurement result is received from the measurement device 20 (step S611: No), the process is terminated. In addition, when the response received from the measurement apparatus 20 does not include the measurement result, for example, when the measurement conditions are not satisfied for all the request items, the configuration in which the processing is similarly ended may be employed.

  When the communication unit 301 receives the measurement result from the measurement device 20 (step S611: Yes), the notification generation unit 312 increments the “number of measurements within the period” in the measurement device DB 322 by 1 (step S612). It should be noted that the configuration may be such that “measurement count within period” is not incremented when measurement results are not obtained for some of the required items.

  Next, the notification generation unit 312 determines whether another measurement result is received for the protected person within a predetermined period from the date and time when the measurement result is received. When other measurement results have been received (step S613: Yes), the result calculation unit 314 calculates the average value by reading the plurality of measurement results or graphs the time-series changes. Is performed (step S614). The processing by the result calculation unit 314 will be described later.

  When other measurement results have not been received (step S613: No), the notification generation unit 312 refers to the protected person DB 321 and the guardian DB 323, and the desired contact method with the guardian who is the measurement result notification destination. The notification timing is acquired (step S615). Next, the notification generation unit 312 provides a result notification to the guardian terminal 40 through the communication unit 301 at the notification timing and method acquired from the guardian DB 323 (step S616).

  Next, the point calculation unit 313 calculates the points to be given to the measuring device 20 with reference to the protected person DB 321 and records them in the measuring device DB 322 (step S617). In this embodiment, as shown in FIG. 6, the guardian DB 321 records that the point given when the measurement result is acquired for the guardian ID “000000” is “30”. Therefore, the point calculation unit 313 adds “30” to the “point” column in the row of the measurement device ID “200000” in the measurement device DB 322 illustrated in FIG. 7.

  In addition, when there are a plurality of request items associated with the person to be protected, and measurement values can be acquired from the measurement device 20 only for some of the request items, a part of “points to be given” is subtracted and given. Such a configuration may be adopted. In addition, instead of predetermining “points to be granted” in the protected person DB 321, it may be configured to calculate at random each time a measured value is acquired.

  Next, processing by the result calculation unit 314 will be described. For example, when the measuring device with the measuring device ID “200002” is also included in the communication range of the beacon device 10 that has transmitted the beacon signal to the measuring device ID “200000”, the management server 30 also receives a message from the measuring device, Send a measurement request. FIG. 13 is an explanatory diagram illustrating an example of a data structure of a second measurement request according to the embodiment. As shown in FIG. 7, the measuring device with the measuring device ID “200002” is not equipped with the sensor “PM2.5” and does not allow the measurement value of “humidity” to be provided. In the second measurement request shown in FIG. 2, the columns “Required Item 1” and “Required Item 3” are “N / A”. The request generation unit 311 may be configured to exclude a request item that does not request measurement from the measurement device 20 and transmit a measurement request including only one request item.

  The measurement apparatus that has received the measurement request transmits the measurement result to the management server 30. FIG. 14 is an explanatory diagram illustrating an example of a data structure of a second measurement result according to the embodiment. In the second measurement result shown in FIG. 14, the column “Measurement device ID” is “20002”. Further, “N / A” in the columns of “Required item 1” and “Required item 3” indicates that measured values of “PM2.5” and “humidity” are not acquired.

  When the result calculation unit 314 of the management server 30 receives the second measurement result through the communication unit 301, the result calculation unit 314 performs calculation processing using the measurement result illustrated in FIG. 4 and the second measurement result illustrated in FIG. The result is output to the notification generator 312. In this embodiment, the result calculation unit 314 receives the temperature “30.8 ° C.” received from the measurement device with the measurement device ID “200000” and the temperature “26.6” received from the measurement device with the measurement device ID “200002”. The average value “28.7 ° C.” with “° C.” is calculated.

  FIG. 15 is an explanatory diagram illustrating an example of a data structure of a second result notification according to the embodiment. In FIG. 15, the columns “guardian name”, “protected person name” and “protected person attribute” in the second result notification are the same as those in the result notification shown in FIG. The "" column includes two measurement device IDs "200000" and "200002". The column “Measurement Date / Time” includes from the date / time measured by the first measuring device to the date / time measured by the last measuring device. The column “temperature” includes the average value calculated by the result calculation unit 314. The number in parentheses indicates the number of received environmental information measurement values. “N / A” in the “humidity” column indicates that no humidity measurement value has been acquired. In addition, the structure which displays the positional information acquired from the measuring apparatus 20 on a map, or graphs a time-sequential change may be provided to the guardian's terminal 40.

  According to the above embodiment, the measurement device 20 that has received the beacon signal from the beacon device 10 of the protected person, the environmental data around the protected person instructed by the management server 30 is measured and transmitted to the management server 30, The management server 30 provides the measured value to the guardian terminal 40. Thereby, the guardian can acquire the environmental information of the guardian without giving the guardian a large-scale device equipped with various sensors. Note that many dedicated terminals that only have the function of transmitting a beacon signal are small and can be driven for a long time, reducing the burden on the guardian compared to providing the guardian with a measuring device or general-purpose terminal. it can.

  Although the embodiments of the present invention have been described so far, the present invention may be implemented in various different forms other than the above-described embodiments. For example, the processes shown in FIG. 11 or FIG. 12 are not limited to the above order, and may be performed at the same time as long as the processing contents are not inconsistent, or may be performed in a different order.

  In addition, among the processes described in the present embodiment, all or a part of the processes described as being automatically performed can be manually performed. Alternatively, all or part of the processing described as being performed manually can be automatically performed by a known method. In addition, the processing procedure, control procedure, specific name, and information including various data and parameters shown in the above-described document and drawings can be arbitrarily changed unless otherwise specified.

  Further, each component of each illustrated apparatus is functionally conceptual, and does not necessarily need to be physically configured as illustrated. That is, the specific form of distribution / integration of each device is not limited to that shown in the figure. That is, all or a part of them can be configured to be functionally or physically distributed / integrated in arbitrary units according to various loads or usage conditions. For example, the request generation unit 311 and the notification generation unit 312 can be integrated, or software installed in the management server 30 can be distributed to a plurality of computer systems. Further, all or any part of each processing function performed in each device may be realized by a CPU and a program analyzed and executed by the CPU, or may be realized as hardware by wired logic.

[Maximum number of measurements]
In the embodiment described above, the measurement device DB 322 stores the upper limit of the number of times that the measurement device 20 can measure, but the protected person DB 321 stores the protected person ID and the “upper limit number” in association with each other, and the protected person. The maximum number of times may be set for. Moreover, the structure which does not set the upper limit of the frequency | count which the measuring apparatus 20 can measure may be sufficient.

[Reduction of unnecessary communication]
When it is clear that the measurement device 20 has not received a measurement request from the management server 30, such as when the measurement server 20 has already received a notification of “exceeding the number of measurements” from the management server 30, The configuration may be such that the device ID is not transmitted.

[Measurement condition judgment method]
In the above-described embodiment, the management server 30 transmits the measurement conditions of the request item to the measurement apparatus 20 and determines whether or not the measurement apparatus 20 satisfies the measurement conditions. However, the measurement condition determination method is not limited to this. Absent. For example, when the measurement condition can be confirmed on the management server 30 side like the current time, it is determined whether the measurement condition is satisfied on the management server 30 side, and if not, the measurement request is not transmitted. May be. In addition, when the measurement device 20 transmits a message to the management server 30, the measurement device DB 322 stores the measurement server DB 322 that stores the measurement device DB 322, which transmits a message that is specific to the measurement device 20 such as the remaining battery level. It may be configured to determine whether or not the condition is satisfied.

[Omitted some information to be sent and received]
For example, the message transmitted from the measurement device 20 to the management server 30 may be configured so as not to include the measurement device ID, or may be configured so that the measurement request does not include the measurement condition.
