Description

  The present invention relates to a technique for notifying a position of a movable wireless communication device.

  There is a wireless tag position search system in which a wireless tag (wireless communication device) attached to a person, a pet, an article, or the like reports position information acquired by GPS (Global Positioning System) or the like. The battery incorporated in such a wireless tag is desired to be as small as possible in consideration of portability. Therefore, frequently performing GPS reception, wide-area wireless communication, and the like that consumes a large amount of power increases the possibility that a battery capacity that is not very large will be lost.

  As a related technique for such a problem, Patent Document 1 discloses a position detection method in which a position detection device transmits a GPS positioning result through a mobile phone network. In the method described in Patent Document 1, the position detection device determines the movement of its own device based on the result of communication with a base station that consumes less power than GPS, thereby reducing the number of times GPS is used. be able to.

  Patent Document 2 discloses a mobile phone device that reduces power consumption when it exists outside a mobile wireless communication service for a long period of time. The mobile phone device with a GPS function described in Patent Document 2 can reduce power consumption by reducing synchronization trial communication with an unnecessary base station based on periodic GPS positioning.

  The wireless communication device disclosed in Patent Literature 3 detects the electric field strength of radio waves from the tag and the movement of the wireless communication device when performing wireless communication with a tag including a short-range wireless communication module. Based on the sensor, the position of the tag is estimated. That is, this wireless communication device can measure the position by measuring the electric field intensity and the operation of the sensor, which consumes less power than GPS.

  Further, in Patent Document 4, in the wireless tag search system, the signal transmission interval from the wireless tag is set according to the number of wireless tags located in the wireless search area and the speed at which the wireless tag moves away from the tag search device. A wireless tag searching method to be controlled is disclosed.

  However, the position detection method disclosed in Patent Document 1 has a problem that the accuracy of position information is low. The reason is that it is not considered that the mobile station has moved unless there is a change in the base station to which the position detection apparatus is waiting.

  Further, the mobile phone device disclosed in Patent Literature 2 has a problem that the number of GPS positioning cannot be reduced. In addition, there is a problem that the operation for reducing communication in the mobile phone device is limited to a case where the operation is performed outside the mobile wireless communication service area for a long period of time. That is, it can be said that the effect of reducing the power consumption in this cellular phone device is limited in both the amount of power that can be reduced and the opportunity.

  In addition, in the wireless communication device and the wireless tag search system disclosed in Patent Documents 3 and 4, the range in which positioning is possible is limited to the case where the tag and the wireless communication device are located at positions where short-range wireless communication is possible. There's a problem.

  One object of the present invention is to provide a wireless communication device and the like that reduce power consumption due to positioning while suppressing a decrease in accuracy of position information without limiting the range in which positioning is possible.

  In order to achieve the above object, a wireless communication apparatus according to one embodiment of the present invention includes the following configuration.

It is a block diagram which shows the structure of the radio | wireless communication apparatus 1 which concerns on the 1st Embodiment of this invention. It is a block diagram which shows an example of the communication environment in the positional information notification system which concerns on the 2nd Embodiment of this invention. 6 is a flowchart illustrating an operation performed by the wireless communication device 100 in the second embodiment. It is a figure which illustrates the structure of the computer (information processing apparatus) applicable to each embodiment of this invention and the positional information notification system which concerns on the modification.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

<First Embodiment>
FIG. 1 is a block diagram showing a configuration of a wireless communication apparatus 1 according to the first embodiment of the present invention. Referring to FIG. 1, the wireless communication device 1 according to the present embodiment includes a positioning unit 3, a movement measuring unit 4, a location information management unit 5, and a notification unit 6.

  The wireless communication device 1 may be configured by a general information processing device (computer) that operates under the control of a computer program (software program) that is executed using a CPU (Central Processing Unit: not shown). . Alternatively, each unit of the wireless communication device 1 may be configured by a dedicated hardware device or a logic circuit. A hardware configuration example in which the wireless communication device 1 is realized by a computer will be described later with reference to FIG.

  The wireless communication device 1 can communicate with a base station (not shown) via wireless communication. The wireless communication apparatus 1 can communicate with a server or the like (not shown) via a base station (not shown).

  The positioning unit 3 can acquire position information indicating the position of the own device. The positioning unit 3 is controlled by the position information management unit 5.

  The movement measuring unit 4 can continuously measure the movement state of the own device. The movement status may include, for example, various information such as a movement distance, a movement direction, a moving time (a time during which the movement has not been performed), and a moving speed.

  The position information management unit 5 acquires the position information of the own device by the positioning unit 3 based on the movement state measured by the movement measurement unit 4. The position information management unit 5 may determine the timing for acquiring the position information based on at least one piece of information included in the movement status measured by the movement measurement unit 4. The location information management unit 5 passes the acquired location information of the own device to the notification unit 6.

  The notification unit 6 notifies the position information of the own device acquired by the control of the position information management unit 5 to a server (not shown) or the like via wireless communication.

  Thus, in this embodiment, the positioning (acquisition of position information) by the positioning unit 3 is executed based on the movement status. For example, the position information management unit 5 can wait for positioning and notification when there is little movement and the change in position is small. Therefore, this embodiment can be expected to reduce the number of times of positioning as compared with the case where positioning is performed periodically.

  Furthermore, in recent years, it is possible to measure a change in position with higher accuracy than a change in a base station that is a standby unit for wireless communication by a movement measurement method using a general sensor or the like. In addition, for example, when the movement is intense and the position change is large, the position information management unit 5 can also frequently perform positioning and notification. That is, according to the present embodiment, it is possible to suppress a decrease in accuracy of position information. Like the above-described measurement of the movement status by a general sensor, the movement measurement unit 4 can employ a method that does not depend on the surrounding environment, such as whether or not near field communication is possible. The positioning unit 3 can also employ a method that does not depend on the surrounding environment in which the own device exists.

  As described above, according to the present embodiment, it is possible to reduce the number of times the positioning unit 3 obtains the position information of the own device according to the movement status of the own device. Therefore, this embodiment can provide the wireless communication device 1 that does not limit the range in which positioning is possible and reduces power consumption due to positioning while suppressing a decrease in accuracy of position information. Such an effect can be expected to be prominent when the difference in power consumption between the positioning unit 3 and the movement measuring unit 4 is large.

  The reason is that the position information management unit 5 can determine the acquisition timing of the position information of the own device by the positioning unit 3 based on the movement state of the own device measured by the movement measuring unit 4.

  In addition, according to the present embodiment, the range in which positioning is possible is not limited, and the number of times of notification transmission to the server or the like by the notification unit 6 can be reduced while suppressing a decrease in accuracy of position information. Therefore, this embodiment can be expected to have effects of reducing battery consumption of the wireless communication device 1 by wireless communication and suppressing congestion of the wireless communication band.

  The reason is that the position information management unit 5 instructs the acquisition of the position information of the own device and the transmission of the notification to the notification unit 6 based on the movement status of the own device measured by the movement measuring unit 4. is there.

  Moreover, according to this embodiment, according to the difference in the characteristics of the positioning unit 3 and the movement measuring unit 4, various effects can be obtained in addition to the reduction of power consumption. For example, when the communication amount or the communication band is different between the positioning by the positioning unit 3 and the movement status measurement by the movement measuring unit 4, an effect such as a reduction in the communication amount or proper use of the communication band is expected according to this embodiment. it can.

  In addition, the following can be considered as a modification of this embodiment.

  For example, the movement measuring unit 4 may be a functional unit that can acquire position information different from the positioning unit 3. For example, such a movement measurement unit 4 can obtain the movement status continuously by periodically acquiring the position information and calculating the displacement from the previously acquired position information.

  The sensor unit 180 includes a movement measurement unit 140 and a temperature / humidity sensor 181. The movement measuring unit 140 includes an acceleration sensor 141, a geomagnetic sensor 142, and a gyro sensor 143.

The movement status, temperature, and humidity measurement results measured by the sensor unit 180 are passed to the position information management unit 150.

  The location information management unit 150 acquires the location information of its own device by the GPS unit 130 based on the movement status measured by the movement measurement unit 140. In the present embodiment, the location information management unit 150 also receives the location information of its own device by the GPS unit 130 when receiving a notification from the wireless communication control unit 120 that location registration for the base station 200 is required.

  The notification unit 160 notifies the server 300 of the location information of the own device received from the location information management unit 150 via the wireless communication control unit 120 via wireless communication. In the present embodiment, the notification unit 160 can also send the movement history information 171 and additional information when transmitting the position information of the own device. The additional information is information other than the position information generated at the position where the wireless communication apparatus 100 is located and the movement history information 171. In the present embodiment, the notification unit 160 can also send additional information representing the temperature and humidity measured by the temperature / humidity sensor 181.

The GPS unit 130, the movement measurement unit 140, the location information management unit 150, and the notification unit 160 are the same as those in the first embodiment except for the points described above, and thus a detailed description thereof is omitted.

  The server 300 includes a communication control unit 301, a control unit 302, and a storage device 303. As described above, the server 300 can also be called an information processing apparatus.

  The storage device 303 can store information received from the wireless communication device 100 under the control of the control unit 302. The storage device 303 need not be built in the server 300. For example, the storage device 303 may be a storage device connected via any communication network.

  Next, the operation of the present embodiment having the above-described configuration will be described in detail. First, the premise in the following description will be described.

  In the position information system according to the present embodiment, the moving wireless communication device 100 notifies the server 300 of the position information of the own device, the movement history information indicating the progress of movement, and additional information such as temperature and humidity. In this position information notification system, for example, the wireless communication device 100 is attached as a wireless tag to a person, a pet, a vehicle, or the like. Hereinafter, the wireless communication device 100 is also referred to as a wireless tag. The position information, movement history information, and additional information of the wireless tag stored in the server 300 may be referred to by a terminal (not shown) for the purpose of searching for an object to which the wireless tag is attached, for example. Considering the portability of the wireless tag, it is desirable that the battery built in the wireless tag is as small as possible.

  In the present embodiment, the magnitude of power consumption in the wireless communication device 100 decreases in the order of wide area wireless communication >> GPS reception by the GPS unit 130 >> movement measurement by the movement measurement unit 140> wide area communication standby. In the above, “A> B” indicates that the operation A is relatively larger than the operation B. “A >> B” indicates that the difference in power consumption is larger than the description “A> B”. That is, if wide-area wireless communication and GPS reception are frequently performed, the power saving performance of the wireless communication device 100 is significantly degraded. The present embodiment is an example of reducing the power consumption of the wireless communication device 100 based on the difference in characteristics such as the magnitude of power consumption between the GPS unit 130 and the movement measurement unit 140.

  The above is the premise in the following description.

  Next, a detailed operation will be described with reference to FIG. FIG. 3 is a flowchart illustrating an operation performed by the wireless communication device 100 in the second embodiment. Referring to FIG. 3, first, the movement measuring unit 140 measures the movement state (step S10). Specifically, in the present embodiment, the movement measuring unit 140 includes the trajectory information that represents the trajectory of movement and the measurement time that represents the measurement time obtained by integrating the measured values of the acceleration sensor 141, the geomagnetic sensor 142, and the gyro sensor 143. Information is output as the movement status. As a method for integrating the measurement results of the acceleration sensor 141, the geomagnetic sensor 142, and the gyro sensor 143 and outputting the result as movement trajectory information, a well-known general method can be adopted, and a detailed description thereof will be given. Omitted. The movement measurement unit 140 periodically outputs the measured movement status to the position information management unit 150.

  The position information management unit 150 records the movement status received from the movement measurement unit 140 in the storage device 170 as movement history information 171 (step S11). In the present embodiment, as an example, the movement history information 171 includes at least trajectory information that represents the trajectory that the device has moved, and movement time information that represents the time at which the trajectory information was measured. The position information management unit 150 may include the position information of the reference point where the movement is started as the movement history information 171. The position information of the reference point is the latest value measured by the GPS unit 130. If positioning by the GPS unit 130 has not been performed yet, the position information management unit 150 may use the initial reference point as a temporary coordinate. Alternatively, the position information management unit 150 may obtain initial reference point information by performing initial position measurement with the GPS unit 130 after the wireless communication device 100 is activated.

  Next, the position information management unit 150 determines whether or not the movement distance from the previously notified position is greater than a predetermined value (step S12). The “position notified last time” is a position when the notification unit 160 last notifies the server 300. As will be described later in steps S <b> 17 and S <b> 20, the position information management unit 150 updates the reference point with the latest position information when performing notification. Specifically, based on the movement history information 171, the position information management unit 150 calculates a movement distance that is a distance between the point reached by moving from the reference point and the reference point.

  When the moving distance is smaller than the predetermined value (NO in step S12), the wireless communication device 100 returns to the operation in step S10.

  When the movement distance is larger than the predetermined value (YES in step S12), the position information management unit 150 determines whether or not the movement stop time is longer than the predetermined time T1 (step S13). Specifically, first, the location information management unit 150 traces back from the latest movement history information 171 to the past, the time during which the movement of the own device is generally stopped (the movement is stopped). Time). That is, the time during which the movement is stopped is a time during which it can be considered that the aircraft is generally staying at the current position. The position information management unit 150 may determine that the movement is stopped with a predetermined width for the degree of movement. Then, the position information management unit 150 compares the calculated time during which the movement is stopped with a predetermined time T1.

  When the time during which the movement is stopped is shorter than the predetermined time T1 (NO in step S13), the wireless communication device 100 returns to the operation in step S10.

  When the time during which the movement is stopped is longer than the predetermined time T1 (YES in step S13), the position information management unit 150 determines whether or not the elapsed time from the previous notification is longer than the predetermined time T2 (step S14). ). The “previous notification” is a notification that the notification unit 160 makes last to the server 300. When the notification has not been performed yet, the position information management unit 150 determines that the elapsed time from the time of the previous notification is longer than the predetermined time T2.

  When the elapsed time from the time of the previous notification is shorter than the predetermined time T2 (NO in step S14), the wireless communication device 100 returns to the operation in step S10.

  When the elapsed time from the time of the previous notification is longer than the predetermined time T2 (YES in step S14), the position information management unit 150 measures the position by the GPS unit 130 (step S15). That is, the position information management unit 150 has been in a state where the movement distance is larger than a predetermined value and the movement is stopped longer than the predetermined time T1, and more than the predetermined time T2 has elapsed since the previous notification was performed. In this case, it is determined to acquire and notify new position information. The GPS unit 130 performs positioning by receiving GPS under the control of the position information management unit 150. The GPS unit 130 outputs the acquired position information to the position information management unit 150.

  The position information management unit 150 that has received the position information from the GPS unit 130 instructs the notification unit 160 to make a new notification to the server 300. Specifically, the position information management unit 150 outputs position information, the contents of the movement history information 171 recorded since the previous notification, and information indicating temperature and humidity to the notification unit 160. For example, the position information management unit 150 may acquire information representing the current temperature and humidity from the temperature / humidity sensor 181 in step S15. Alternatively, the position information management unit 150 may acquire information representing the temperature and humidity from the temperature / humidity sensor 181 when receiving the movement status from the movement measurement unit 140 in step S10.

  The notification unit 160 generates a notification including the position information, the contents of the movement history information 171 recorded after the previous notification, and additional information indicating temperature and humidity. Then, the notification unit 160 transmits a notification to the server 300 via the wireless communication control unit 120. When transmitting the notification, the wireless communication control unit 120 determines whether or not location registration for the base station 200 is necessary (step S16). Specifically, the wireless communication control unit 120 determines whether any base station 200 is in a standby state for wide area wireless communication. If the wireless communication control unit 120 is already in a standby state for wide area wireless communication, the wireless communication control unit 120 determines that location registration with respect to the base station 200 is unnecessary.

  When the location registration with respect to the base station 200 is not required (NO in step S16), the wireless communication control unit 120 starts the notification information transmission operation to the server 300 as it is from the standby state. That is, the wireless communication control unit 120 notifies the server 300 of the position information, the movement history information, and the additional information instructed to be transmitted from the notification unit 160 (step S17).

  When location registration with respect to the base station 200 is necessary (YES in Step S16), the wireless communication control unit 120 transmits notification to the server 300 together with location registration with the base station 200 (Step S20). Specifically, the wireless communication control unit 120 sends a notification to the server 300 between a series of communication sequences in the location registration operation for the base station 200 or following the communication sequence. Note that the operation of “location registration to the base station 200” includes a series of communication protocol processing for the base station 200 performed when performing wide area wireless communication.

  After the notification is transmitted, the reference point for movement measurement is updated with the notified position information. Then, the wireless communication device 100 returns to the operation of Step S10 again and repeats the above-described operation.

  The base station 200 transmits the notification sent from the wireless communication apparatus 100 to the server 300 via the communication network 1000. In the server 300, the control unit 302 receives the notification via the communication control unit 301. The control unit 302 can accumulate information included in the received notification in the storage device 303.

  As described above, the present embodiment has an effect that the movement history information 171 and the additional information can be transmitted to the server 300 in addition to the same effects as those of the first embodiment described above. As a result, for example, it is possible to expect an effect that it is easy to find an object to which a wireless tag (wireless communication device 100) is attached based on information stored in the storage device 303 of the server 300.

  The reason is that the position information management unit 150 records the movement status measured by the movement measurement unit 140 as the movement history information 171. This is because the notification unit 160 notifies the server 300 of the recorded movement history information 171 and the additional information acquired by the sensor unit 180 together with the position information. For example, the searcher may be able to infer that the object is in the warehouse by the temperature and humidity around the wireless tag. Further, the searcher may be able to guess the future destination of the object based on the movement history.

  In addition, this embodiment also has an effect that the server 300 can be notified of the location where the wireless communication device 100 is stopped. As a result, for example, it is possible to expect an effect that it is easy to find a person with a wireless tag based on information stored in the storage device 303 of the server 300.

The reason is that the position information management unit 150 is in a state where the movement distance is larger than a predetermined value and the movement is stopped longer than the predetermined time T1, and further longer than the predetermined time T2 since the previous notification was performed. This is because when the time has elapsed, acquisition and notification of new position information are performed. In general, when searching for a moving wireless tag, the notification that the wireless tag is stopped and the information indicating the position are more effective than the moving position information.
(Modification of the second embodiment)
In addition, the following can be considered as a modification of this embodiment.

  For example, the determination method for determining the timing at which the position information management unit 150 performs the positioning by the GPS unit 130 and the notification by the notification unit 160 shown in steps S12 to S14 is an example. The position information management unit 150 may rearrange the order of determination performed in steps S12 to S14. The location information management unit 150 may determine the timing of positioning and notification by combining some of the determinations performed in steps S12 to S14 or by any one determination.

  In addition, the wireless communication device 100 may notify the server 300 including a history of additional information accompanying movement. Specifically, for example, in step S <b> 10, the temperature / humidity sensor 181 outputs the measurement result to the position information management unit 150 in the same manner as each unit of the movement measurement unit 140. The position information management unit 150 records the measurement results (temperature and humidity) received from the temperature / humidity sensor 181 as additional information in addition to the movement history information 171. The position information management unit 150 outputs movement history information 171 including additional information to the notification unit 160 when instructing transmission of the notification in step S16. The notification unit 160 includes the additional information included in the movement history information 171 in the notification and transmits it to the server 300. In this way, there is also an effect that the temperature / humidity management state and the like during the movement of the object with the wireless tag can be recorded.
