The information collection method 502 of the information collection system 500 according to the present embodiment will be described with reference to FIGS.

<Wearable device processing S100>
The wearable device process S100 includes a collection process S10, a determination process S11, an interval change process S12, and an interval return process S13.

<Collection process S10>
In step S <b> 101, the collection unit 110 periodically collects physical information 111 regarding the human body. Specifically, the collection unit 110 collects vital information such as pulse and body temperature and state information such as acceleration data of a person wearing the wearable device 100 as physical information 111 using the sensor 196. The collection unit 110 periodically collects the physical information 111 at the first interval T1.

<Determination process S11>
In step S102, the determination unit 120 determines whether the body information 111 is abnormal. Specifically, the determination unit 120 determines whether or not the body information 111 is abnormal by comparing the body information 111 collected by the collection unit 110 with a reference value 131.
If the physical information 111 is not abnormal, the determination unit 120 transmits the collected physical information 111 to the mobile terminal device 200 in step S103.
If the physical information is abnormal, the determination unit 120 transmits a physical alarm 151 to the mobile terminal device 200 in step S104. The physical alarm 151 includes information regarding the wearer wearing the wearable device 100.

<Interval change processing S12>
In step S <b> 105, the collection unit 110 receives an interval change instruction 601 from the interval change instruction unit 220 of the mobile terminal device 200. Specifically, the collection unit 110 receives an interval change instruction 601 from the interval change instruction unit 220 via the communication device 195.
In step S <b> 106, the collection unit 110 changes the interval for collecting the body information 111 based on the interval change instruction 601 transmitted from the interval change instruction unit 220. Specifically, the collection unit 110 changes the interval for collecting the body information 111 from the first interval T1 to the second interval T2 based on the interval change instruction 601. The second interval T2 is included in the interval change instruction 601, for example.
In step S107, the collection unit 110 periodically collects the body information 111 at the second interval T2. Specifically, the collection unit 110 uses the sensor 196 to periodically collect the body information 111 at the second interval T2.
In step S <b> 108, the collection unit 110 transmits the body information 111 collected at the second interval T <b> 2 to the mobile terminal device 200 as abnormal time information 602. Specifically, the collection unit 110 transmits the abnormal time information 602 to the mobile terminal device 200 via the communication device 195. The abnormal time information 602 includes the wearer's physical information 111 collected at the second interval T2.

<Interval return processing S13>
In step S <b> 109, the collection unit 110 receives an interval return instruction 341 from the mobile terminal device 200.
In step S110, the collection unit 110 returns the interval for collecting the physical information 111 from the second interval T2 to the first interval T1 in accordance with the interval return instruction 341 transmitted from the mobile terminal device 200.

<Mobile terminal processing S200>
The portable terminal process S200 includes a data communication process S20, an interval change instruction process S21, an abnormality process S22, and an interval return instruction transfer process S23.

<Data communication process S20>
In step S201, the data communication unit 210 receives data via the communication device 295 and determines the received data. If the received data is the physical information 111, the process proceeds to step S201a. If the received data is the body alarm 151, the process proceeds to step S203. If the received data is abnormal time information 602, the process proceeds to step S204.

  In step S201a, the data communication unit 210 receives the body information 111 transmitted from the determination unit 120, and determines whether the body information 111 is acceleration data or vital data. In the case of acceleration data, the process proceeds to step S201b. In the case of vital data, the process proceeds to step S202.

In step S201b, the data communication unit 210 determines whether or not the acceleration data acquisition interval is long.
Specifically, the data communication unit 210 stores the received acceleration data in the body information storage unit 241 and acquires an acquisition interval of the received acceleration data. The data communication unit 210 may acquire an acquisition interval included in the acceleration data transmitted from the determination unit 120. Alternatively, the data communication unit 210 may acquire the acquisition interval from the acceleration data acquisition time transmitted from the determination unit 120 and the acceleration data acquisition time before and after the acceleration data. The data communication unit 210 compares the interval threshold value 242 stored in the storage unit 240 with the acquired acquisition interval, and determines that the acquisition interval is long when the acquisition interval is equal to or greater than the interval threshold value 242. Further, when the acquisition interval is shorter than the interval threshold value 242, the data communication unit 210 determines that the acquisition interval is not long. When the acquisition interval is long (when the acquisition interval is greater than or equal to the interval threshold 242), the process proceeds to step S202. When the acquisition interval is not long (when the acquisition interval is shorter than the interval threshold 242), the process proceeds to step S201c.
That is, when the physical information 111 is acceleration data, the data communication unit 210 compares the acquisition interval of acceleration data with the interval threshold value 242 that is a threshold value of the acquisition interval, and when the acquisition interval is equal to or greater than the interval threshold value 242. The acceleration data is transmitted to the server device 300.

In step S201c, the data communication unit 210 determines whether or not the load 222 of the mobile terminal device 200 is low. If the load 222 of the mobile terminal device 200 is low, the process proceeds to step S202. If the load 222 of the mobile terminal device 200 is high, the process proceeds to step S201d. Here, the load 222 of the mobile terminal device 200 refers to a CPU load or a communication load of the mobile terminal device 200.
Specifically, the data communication unit 210 acquires the load 222 of the mobile terminal device 200 using a CPU load monitoring tool or a communication load monitoring tool provided by the operation system of the mobile terminal device 200. The data communication unit 210 compares the load 222 of the mobile terminal device 200 with a load threshold value 244 that is a threshold value of the load 222. The load threshold value 244 is stored in the storage unit 240. The data communication unit 210 determines that the load 222 of the mobile terminal device 200 is low when the load 222 of the mobile terminal device 200 is equal to or less than the load threshold 244. The data communication unit 210 determines that the load 222 of the mobile terminal device 200 is high when the load 222 of the mobile terminal device 200 is greater than the load threshold 244. The data communication unit 210 transmits acceleration data to the server device 300 when the load 222 of the mobile terminal device 200 is low (when the load 222 of the mobile terminal device 200 is equal to or less than the load threshold value 244).

In step S201d, the data communication unit 210 determines whether or not acceleration data is accumulated in the body information storage unit 241 for a predetermined time 245 or more. If it is determined by the data communication unit 210 that the physical information storage unit 241 has accumulated 245 or more of the predetermined time, the process proceeds to step S202. When the data communication unit 210 determines that the predetermined time 245 or more has not elapsed since the acceleration data was started to be accumulated in the physical information storage unit 241, the process proceeds to step S201e.
