When it is determined that the predetermined temperature change is not detected (No in step S102), the controller 10 ends the processing procedure illustrated in FIG. That is, the controller 10 ends the process because the place where the user is moving has not changed.

When the controller 10 determines that the predetermined temperature change is detected in step S101 (Yes in step S102), the process proceeds to step S103.

For example, the controller 10 identifies estimated information that matches or is similar to a predetermined temperature change from the setting data 9Z, and estimates the place indicated by the estimated information as a safe place/unsafe place where the user has moved. When the estimation is completed, the controller 10 advances the process to step S104.

The controller 10 determines whether the estimated place is a safe place based on the estimation result of step S103 as step S104. When the controller 10 determines that the estimated place is a safe place (Yes in step S104), the process proceeds to step S105. The controller 10 sets the information which shows a safe place in the estimated data 9G as step S105. The information indicating the safe place may be, for example, information indicating the user's home, office, car, school or the like. When the process of step S105 ends, the controller 10 ends the processing procedure illustrated in FIG.

When the controller 10 determines that the estimated place is not a safe place (No in step S104), the process proceeds to step S106. The controller 10 sets the information which shows an unsafe place in the estimation data 9G as step S106. When the process of step S106 ends, the controller 10 ends the process procedure illustrated in FIG.

As shown in FIG. 2, the electronic device 1 can estimate the change of the place according to the movement of the user based on the detection result of the temperature sensor 19. As a result, the electronic device 1 can control the process according to the current location of the user by estimating the current location of the user carrying the own device.

The notification timing includes, for example, the timing at which the communication unit 6 receives a radio wave from an external electronic device. The notification timing includes, for example, the timing when the position detected by the GPS receiver 18 approaches a predetermined location. The predetermined place includes, for example, intersections, places where traffic accidents frequently occur, and the like. When the controller 10 determines that it is not the notification timing (No in step S1001), it ends the processing procedure shown in FIG. When the controller 10 determines that it is the notification timing (Yes in step S1001), the process proceeds to step S1002.

The controller 10 acquires the estimated data 9G from the storage 9 as step S1002, and advances a process to step S1003. The controller 10 determines whether the safe place is set based on the estimation result of the estimation data 9G as step S1003.

When the controller 10 determines that the safe place is set (Yes in step S1003), the process proceeds to step S1004. The controller 10 sets a 1st value as a user's risk degree as step S1004. The degree of danger of the user indicates, for example, the degree to which the driver of the vehicle is notified of the presence of the user. For example, a driver of a driving vehicle needs to be more careful of a user walking outdoors than a user indoors in order to avoid a traffic accident. That is, the higher the risk level of the user, the higher the driver's attention to the existence of the user. When the process of step S1004 ends, the controller 10 advances the process to step S1006 described below.

When the controller 10 determines that the safe place is not set (No in step S1003), the process proceeds to step S1005. The controller 10 sets a 2nd value as a user's risk degree as step S1005. The second value is a value indicating a higher degree of risk than the first value. When the process of step S1005 ends, the controller 10 advances the process to step S1006.

In step S1006, the controller 10 creates notification information including the degree of risk, and advances the processing to step S1007. The controller 10 controls the transmission of the notification information by the communication unit 6 in step S1007. As a result, the communication unit 6 sends out a radio wave including the notification information to the outside of its own device. When the process of step S1007 ends, the controller 10 ends the process procedure illustrated in FIG.

In the processing procedure shown in FIG. 3, the case where the electronic device 1 sends the notification information from the communication unit 6 even when the electronic device 1 estimates the safe place based on the temperature change has been described, but the present invention is not limited to this. For example, the electronic device 1 may not transmit the notification information from the communication unit 6 when the electronic device 1 estimates the safe place based on the temperature change.

FIG. 4 is a diagram showing an example of the relationship between temperature and time according to the movement of the user. In the example shown in FIG. 4, the outdoor temperature is higher than the indoor temperature. In the example shown in FIG. 4, the user has moved from outdoors to indoors. The example shown in FIG. 4 shows an example of a temperature change pattern when a user carries his/her own device in a severe hot area or the like.

In the example shown in FIG. 4, the electronic device 1 can estimate that the user has moved from a safe place to the outside when the temperature sensor 19 detects a predetermined temperature change pattern in which the temperature becomes room temperature after the temperature rises abruptly. On the other hand, in the example shown in FIG. 4, when the electronic device 1 detects a predetermined temperature change pattern in which the temperature becomes normal after the temperature sensor 19 suddenly decreases, the user moves from the outdoors to a safe place. Can be estimated.

FIG. 5: is a figure which shows another example of the relationship between temperature and time according to a user's movement. In the example shown in FIG. 5, the indoor temperature is higher than the outdoor temperature. In the example shown in FIG. 5, the user has moved from indoors to outdoors. The example shown in FIG. 5 shows an example of a temperature change pattern when the user carries his/her own device in a cold region or the like.

In the example shown in FIG. 5, when the temperature sensor 19 detects a predetermined temperature change pattern in which the temperature becomes normal after the temperature sensor 19 in the electronic device 1, it can be estimated that the user has moved from a safe place to the outdoors. On the other hand, in the example shown in FIG. 5, the electronic device 1 detects that the user has moved from the outdoors to a safe place when the temperature sensor 19 detects a predetermined temperature change pattern in which the temperature becomes room temperature after the temperature suddenly rises. Can be estimated.

For example, when the electronic device 1 estimates that the user has moved from a safe place to an unsafe place based on the detection result of the temperature sensor 19, the electronic device 1 sends notification information with a high degree of danger from the communication unit 6 to the outside. It can be sent to electronic devices. As a result, the electronic device 1 can change the value of the degree of risk of the notification information according to the estimation result of whether or not the user is in a safe place.

An electronic device 1 according to another example of the embodiment will be described below. An electronic device 1 according to another example of the embodiment has the same configuration as the electronic device 1 shown in FIG. 1 except that the function of the control program 9A is different.

FIG. 6 is a flowchart showing a processing procedure of another example of control by the electronic device 1. The processing procedure shown in FIG. 6 is realized by the controller 10 executing the control program 9A. The processing procedure shown in FIG. 6 is repeatedly executed by the controller 10.

In the example shown in FIG. 6, the processing from step S102 to step S106 is the same as the processing from step S102 to step S106 shown in FIG. 2, so only different parts will be described and description of the same parts will be omitted.

As shown in FIG. 6, the controller 10 of the electronic device 1 acquires the position information of the own device from the GPS receiver 18 in step S201, and advances the process to step S202. The controller 10 specifies a predetermined temperature change corresponding to the position information of the own device in step S202. For example, when the position information of the own device is the first position information registered in advance such as at home, company, school, etc., the controller 10 determines the predetermined temperature change associated with the first position information from the setting data 9Z. Identify. For example, when the position information of the own device is the second position information registered in advance such as a cold region or a severe heat region, the controller 10 identifies the predetermined temperature associated with the second position information from the setting data 9Z. To do. When the controller 10 identifies the predetermined temperature change, the process proceeds to step S203.

At step S203, the controller 10 analyzes the presence or absence of a predetermined temperature change corresponding to the position information from the detection result of the temperature sensor 19. For example, if the detection result of the temperature data 9F includes a temperature change similar to or matching the predetermined temperature change specified in step S202, the controller 10 detects the temperature change. For example, the controller 10 does not detect the predetermined temperature change when the detection result of the temperature data 9F does not include the predetermined temperature change specified in step S202. When the controller 10 analyzes the presence or absence of a predetermined temperature change, the process proceeds to step S102 already described. The controller 10 ends the processing procedure shown in FIG. 6 when the processing of step S102 and the subsequent steps already described is completed.

As shown in FIG. 6, the electronic device 1 can estimate the change of the place according to the movement of the user based on the detection result of the temperature sensor 19 and the position information of the user. As a result, the electronic device 1 can specify the predetermined temperature change corresponding to the position information of the user. For example, when the location information indicates the vicinity of the user's home, office, school, etc., the user is likely to move from an unsafe place to a safe place. In this case, the electronic device 1 can identify the predetermined temperature change when moving from the unsafe place at the position to the safe place. For example, when the location information indicates the user's home, company, school, etc., the user is likely to move from a safe place to an unsafe place. In this case, the electronic device 1 can identify the predetermined temperature change moving from the safe place at the position to the unsafe place. In this way, the electronic device 1 improves the accuracy of the estimation by estimating whether or not the moved place is a safe place based on a predetermined temperature change according to the current position of the own device. be able to.

For example, when the current position detected by the GPS receiver 18 is a predetermined position, the electronic device 1 may estimate the safe place where the user has moved based on the presence or absence of a predetermined temperature change. .. The predetermined position includes, for example, the position of the user's home, office, school, or the like. The electronic device 1 may specify the current position of the user based on the image captured by the camera 12 or the camera 13, for example. Specifically, the electronic device 1 photographs the surroundings of the electronic device 1 with the camera 12 or the camera 13, and determines whether the photographed image includes an image associated with a predetermined position. The electronic device 1 determines that the current position is the predetermined position when the image associated with the predetermined position is displayed. The information of the image associated with the predetermined position may be recorded in the storage 9 by analyzing the image captured in advance at the predetermined position. The electronic device 1 uses the image captured by another terminal acquired by communicating with another terminal such as a wearable terminal via the communication unit 6 instead of the image acquired by using the camera 12 or the camera 13. May be determined to be a predetermined position.

FIG. 7 is a flowchart showing another example of the processing procedure of the control by the electronic device 1. The processing procedure shown in FIG. 7 is realized by the controller 10 executing the control program 9A. The processing procedure shown in FIG. 7 is repeatedly executed by the controller 10.

In the example shown in FIG. 7, the processing from step S102 to step S106 is the same as the processing from step S102 to step S106 shown in FIG. 2, so only different parts will be described and description of the same parts will be omitted.

As shown in FIG. 7, the controller 10 of the electronic device 1 acquires the position information of the own device from the GPS receiver 18 in step S301, and advances the process to step S302. The controller 10 acquires the weather information of the area corresponding to a positional information from an external electronic device via the communication unit 6 as step S302. For example, the controller 10 acquires meteorological information including temperature information of the vicinity of the current position of the own device, an area, etc. from a predetermined distribution server or the like. When the acquisition process ends, the controller 10 advances the process to step S303.

In step S303, the controller 10 analyzes the presence or absence of a predetermined temperature change based on the detection result of the temperature sensor 19 and the weather information. For example, when the outside temperature of the detected area is 35° C. and the temperature detected by the temperature sensor 19 is 25° C., the user is highly likely to be cool indoors. Therefore, the controller 10 calculates the difference between the temperature detected by the temperature sensor 19 and the temperature indicated by the weather information, and detects the predetermined temperature change when the difference becomes larger than the predetermined threshold value. The controller 10 calculates the difference between the temperature detected by the temperature sensor 19 and the temperature indicated by the meteorological information. If the difference is not larger than the predetermined threshold value, the controller 10 does not detect the predetermined temperature change. When the controller 10 analyzes the presence or absence of a predetermined temperature change, the process proceeds to step S102 already described. The controller 10 ends the processing procedure illustrated in FIG. 7 when the processing of step S102 and the subsequent steps that have already been described is completed.

As shown in FIG. 7, the electronic device 1 can estimate the change in the place according to the movement of the user, based on the detection result of the temperature sensor 19 and the outside air temperature near the current position of the own device. it can. As a result, the electronic device 1 can improve the accuracy of the estimation by estimating whether or not it is a safe place based on a predetermined temperature change based on the outside air temperature.

FIG. 8 is a flowchart showing another example of the processing procedure of the control by the electronic device 1. The processing procedure shown in FIG. 8 is realized by the controller 10 executing the control program 9A. The processing procedure shown in FIG. 8 is repeatedly executed by the controller 10.

In the example shown in FIG. 8, the processing from step S101 to step S106 is the same as the processing from step S101 to step S106 shown in FIG. 2, so only different parts will be described and description of the same parts will be omitted.

As shown in FIG. 8, the controller 10 of the electronic device 1 acquires heat generation information regarding the device itself in step S401. For example, the heat generation information includes information for determining whether or not the device of the own device is generating heat. For example, the heat generation information includes information indicating the usage rate of the controller 10, the usage status, and the like. For example, the heat generation information includes information on the usage status of the device of the own device. When the process is completed, the controller 10 advances the process to step S402.

In step S402, the controller 10 determines whether or not the own device is in a heat generating state. The heat generation state includes, for example, a state in which heat that affects the detection result of the temperature sensor 19 is generated in the own device. For example, if the temperature sensor 19 is generating heat, the temperature sensor 19 may detect a temperature rise due to the heat generation. Therefore, when the acquired heat generation information satisfies the predetermined condition, the controller 10 determines that the own device is in the heat generation state. The predetermined conditions include, for example, a determination condition for determining the usage status of the controller 10 that generates heat, a determination condition for determining the usage status of a device that generates heat, and the like. When the controller 10 determines that the own device is in the heat generation state (Yes in step S402), the controller 10 ends the processing procedure illustrated in FIG.

When the controller 10 determines that the device itself is not in the heat generation state (No in step S402), the process proceeds to step S101 already described. The controller 10 ends the processing procedure shown in FIG. 8 when the processing after step S101 already described is completed.

As illustrated in FIG. 8, the electronic device 1 does not estimate the change in the movement of the user when the device itself may generate heat. When the electronic device 1 does not generate heat, the electronic device 1 can estimate the change of the place according to the movement of the user based on the detection result of the temperature sensor 19. As a result, the electronic device 1 can improve the estimation accuracy of the change of the place based on the temperature by excluding the influence of the heat generation of the electronic device 1.

In the processing procedure shown in FIG. 8, a case has been described in which it is estimated whether or not the place where the user has moved is a safe place unless the own device is in a heat generation state, but the present invention is not limited to this. For example, the processing procedure shown in FIG. 8 is a processing procedure for correcting the detection result of the temperature sensor 19 and estimating whether or not the place where the user has moved is a safe place when the own device is in a heat generating state. May be For example, the processing procedure shown in FIG. 8 may be a combination of the processing procedure relating to the position information of the own device shown in FIG. 6 and the processing procedure relating to the weather information shown in FIG.

FIG. 9 is a flowchart showing a processing procedure of another example of control by the electronic device 1. The processing procedure shown in FIG. 9 is realized by the controller 10 executing the control program 9A. The processing procedure shown in FIG. 9 is repeatedly executed by the controller 10.

In the example shown in FIG. 9, the processing from step S101 to step S106 is the same as the processing from step S101 to step S106 shown in FIG. 2, so only different parts will be described and description of the same parts will be omitted.

As shown in FIG. 9, the controller 10 of the electronic device 1 determines the state of the own device based on the acceleration data 9B in step S501. For example, the controller 10 compares the acceleration pattern of the acceleration data 9B with the acceleration pattern for each state of the determination data 9D, and determines the state corresponding to the matching acceleration pattern of the determination data 9D as the state of the own device. The controller 10 stores the determined state in the state data 9C.

In step S502, the controller 10 determines whether the state of the own device determined in step S501 is a walking state or a running state. When it is determined that the controller 10 is not in the walking state or the traveling state (No in step S502), the controller 10 ends the processing procedure illustrated in FIG. When it is determined that the controller 10 is in the walking state or the running state (Yes in step S502), the controller 10 advances the process to step S101 already described. The controller 10 ends the processing procedure shown in FIG. 9 when the processing of step S101 and the subsequent steps that have already been described is completed.

As shown in FIG. 9, when the electronic device 1 is in a walking state or a running state, is the place where the user has moved based on the detection result of the temperature sensor 19 a safe place? It can be estimated whether or not. For example, the temperature detected by the temperature sensor 19 is highly likely to change rapidly when the environment surrounding the user changes. Therefore, the electronic device 1 can reduce the processing load of the controller 10 by estimating the change in the place when the own device is in the walking state or the running state.

In the above embodiment, the electronic device 1 describes the case where the controller 10 executes each of the processing procedures illustrated in FIGS. 6 to 9, but the invention is not limited to this. For example, the processing procedures shown in FIGS. 6 to 9 may be combined processing procedures. The processing procedure related to the notification shown in FIG. 3 may be combined with the processing procedure shown in FIGS. 6 to 9.

FIG. 10 is a system diagram showing an example of the system configuration of the notification system 100. An example of the notification system 100 including the electronic device 1 will be described with reference to FIG. 10.

As shown in FIG. 10, the notification system 100 includes the electronic device 1, the roadside device 200, and the vehicle 300. The roadside device 200 is provided in a predetermined area or in the vicinity of the predetermined area. The predetermined area includes areas such as roads, intersections, and parking lots, for example. The predetermined area may be, for example, an area including a place where a traffic accident may occur. The roadside device 200 can transmit radio waves to an unspecified number of electronic devices inside and near a predetermined area. The vehicle 300 includes, for example, an automobile, a truck, a bus, a taxi, an emergency vehicle, and the like. The vehicle 300 includes an in-vehicle device 310. The vehicle-mounted device 310 is mounted in the vehicle 300 so that the radio wave from the roadside device 200 can be received, for example. The vehicle-mounted device 310 includes, for example, a vehicle-mounted device such as a navigation device, an ETC (Electronic Toll Collection System) vehicle-mounted device, a combination meter, and a car audio that is mounted on the vehicle 300. The vehicle-mounted device 310 may be, for example, an electronic device brought into the vehicle 300 by a driver. The electronic devices brought into the vehicle 300 include, for example, a mobile phone, a wearable device, a mobile game machine, and the like.

The roadside device 200 and the vehicle-mounted device 310 have a communication unit. The roadside device 200 and the vehicle-mounted device 310 are configured to be capable of bidirectional communication with each other via a communication unit. The roadside device 200 and the vehicle-mounted device 310 are configured to be capable of bidirectional communication by short-distance wireless communication with the electronic device 1 indoors and outdoors through the communication unit. The roadside device 200 includes a function of transmitting information regarding a predetermined area. The in-vehicle device 310 includes a function of providing the received information to the user.

For example, a user carrying the electronic device 1 is walking outdoors. In this case, the user is a traffic vulnerable person who may have a traffic accident with the vehicle 300 such as an automobile or a motorcycle. The electronic device 1 has a function of notifying the driver of the vehicle 300 or the like of the presence of the user in order to protect the weak traffic. The electronic device 1 can detect a stable temperature by the temperature sensor 19 when the user is walking. If the electronic device 1 does not detect a predetermined temperature change from the detection result of the temperature sensor 19, the electronic device 1 estimates that the user is not in a safe place.

As shown in FIG. 10, when the roadside device 200 and the vehicle-mounted device 310 capable of communication exist near the electronic device 1, the electronic device 1 notifies the roadside device 200 and the vehicle-mounted device 310 of the presence of the user. The radio wave including the notification information D for performing is transmitted by the short-range wireless. For example, the notification information D includes information indicating that the risk level of the user is 80% when the possibility that the user is outdoors is high. As a result, the electronic device 1 can notify the presence of the user to the roadside device 200, the in-vehicle device 310, etc., and thus the safety of the user can be improved. On the other hand, when the in-vehicle device 310 receives the notification information D from the electronic device 1 carried by a user who is not in a safe place, for example, the in-vehicle device 310 notifies the driver that a pedestrian who is at risk of popping out is nearby. be able to. As a result, the driver can improve the possibility of avoiding a traffic accident with a vulnerable person such as a pedestrian or a bicycle. When the roadside device 200 receives the notification information D from the electronic device 1 carried by a user who is not in a safe place, the roadside device 200 notifies the vehicle 300 approaching the roadside device 200, the vehicle-mounted device 310, or the like, for example. Information D can be transferred. As a result, the roadside device 200 can contribute to avoiding a traffic accident between the vehicle 300 and a traffic vulnerable person.

For example, a user carrying the electronic device 1 is moving from outdoors to the inside of a building 500 such as a home or a company. In this case, the temperature outside is higher than the temperature inside the building 500. The electronic device 1 detects a predetermined temperature change indicating a rapid temperature decrease based on the detection result of the temperature sensor 19. The predetermined temperature change is associated with a safe place in the estimated information of the setting data 9Z. In this case, the electronic device 1 estimates that the place where the user has moved is a safe place based on the detected predetermined temperature change. The electronic device 1 determines that the state of the electronic device 1 is the walking state based on the detection result of the acceleration sensor 15. For example, when the user is walking in the building 500, the user may jump out of the building 500 to the outside.

The electronic device 1 transmits a radio wave including the notification information D to the roadside device 200, the vehicle-mounted device 310, and the like existing near the building 500 by short-range wireless communication. For example, the notification information D includes information indicating that the risk of the user is 30% when the possibility that the user is walking indoors is high. As a result, the electronic device 1 can notify the roadside device 200, the in-vehicle device 310, and the like of the presence of the user who may jump out of the building 500 to the outside, so that the safety of the user can be improved. On the other hand, the in-vehicle device 310 can notify the driver that, for example, a pedestrian at risk of jumping out of the building 500 is nearby based on the degree of danger of the notification information D received from the electronic device 1. .. As a result, the driver can improve the possibility of avoiding a traffic accident with a vulnerable traffic person who jumps out of the building 500 or the like.

When the roadside device 200 receives the notification information D from the electronic device 1 carried by the user in a safe place, for example, the notification information D is transmitted to the vehicle 300, the vehicle-mounted device 310, or the like approaching the roadside device 200. Can be transferred. As a result, the roadside device 200 can contribute to avoiding a traffic accident between the vehicle 300 and a traffic vulnerable person.

In the above embodiment, the case where the electronic device 1 estimates whether or not the place where the user has moved is a safe place based on a predetermined temperature change has been described, but the present invention is not limited to this. For example, the electronic device 1 may estimate whether or not the user has moved from the inside of the vehicle 300 to the outside, based on the transition of the state of the own device and the predetermined temperature change. For example, the electronic device 1 may estimate that the electronic device 1 has moved from the inside of the vehicle to the outside when the own device makes a transition from a moving state in the vehicle to a walking state and detects a predetermined temperature change corresponding to the transition. Good.

In the above embodiment, the case where the electronic device 1 sets the risk degree of the notification information D to a value of 80% or 30% has been described, but the present invention is not limited to this. For example, the electronic device 1 may be divided into more than two stages as the degree of risk.
