  “Parameter” in the first embodiment means a threshold value, a timer reference value, and software information. Of these, the software information is information in a correspondence table indicating addition timer reference values corresponding to combinations of software types and software states. FIG. 2 shows an example of a device data management table stored in the parameter database 320. As shown in FIG. 2, the device data management table stores control target device data, portable terminal device data, threshold values, and timer reference values in association with each other. On the other hand, FIG. 3 shows an example of the software information management table stored in the parameter database 320. As shown in FIG. 3, the software information management table stores software types, software states, and addition timer reference values in association with each other.

  Hereinafter, the absence determination operation of the control target device 100 configured as described above will be described. FIG. 4 is a diagram for explaining the basic concept of the present absence determination method. This absence determination method uses the point that the received power intensity of the signal from the mobile terminal device 200 measured by the control target device 100 decreases as the distance between the control target device 100 and the mobile terminal device 200 increases. , A boundary line indicating whether the received power intensity is greater than a preset threshold value or less than a threshold value is assumed as a threshold boundary line 400 as shown in FIG. The determination area 401 (that is, the area where it is determined that the user who owns the mobile terminal device 200 is present at the control target device 100), while the area outside the threshold boundary line 400 is the absence determination area. 402 (that is, the area where it is determined that the user who has the mobile terminal device 200 is away from the control target device 100).

  When the control target device 100 compares the received power intensity from the mobile terminal device A of FIG. 4 obtained by measurement with the threshold value, and the received power intensity is larger than the threshold value (that is, inside the threshold boundary line 400). ), It is determined that the mobile terminal device A (the user who owns the mobile terminal device A) is located in the presence determination area 401. On the other hand, the control target device 100 compares the received power intensity from the portable terminal device B of FIG. 4 obtained by measurement with the threshold value, and the received power intensity is equal to or lower than the threshold value (outside the threshold boundary line 400). ), The mobile terminal device B (the user who owns the mobile terminal device B) is determined to be located in the absence determination area 402.

  Here, when it is determined that it is located in the presence determination area 401, it can be used in a state where there is no restriction on the function of the control target device 100. On the other hand, when it is determined that it is located in the absence determination area 402, the absence processing unit 150 makes the control target device 100 unusable. For example, the input operation of the keyboard and mouse mounted on the control target device 100 is stopped, and the display image is not displayed. In the first embodiment, in consideration of the fact that the optimum value of the parameter used for the absence determination differs depending on the device used, the control target device 100 is a device of each of the control target device 100 and the mobile terminal device 200. The data is transmitted to the server apparatus 300, a parameter suitable for the device data is acquired from the server apparatus 300, and the absence determination is performed using the acquired parameter.

  Next, exception handling in the first embodiment will be described. As exception processing in the first embodiment, the determination time measurement unit 142 starts the timer 144 based on the timer reference value obtained from the timer reference value storage unit 122, and the received power intensity before the timer 144 ends. If the value exceeds the threshold value, the execution of the away process is avoided. Here, the software state determination unit 143 acquires the addition timer reference value corresponding to the type and state of software being executed in the control target device 100 from the software information storage unit 123, and adds the above-described timer reference value to the addition timer reference. By adding the value, the timer reference value is adjusted according to the type and state of the software being executed. The software information is acquired from the parameter database 320 of the server device 300.

  Hereinafter, the processing operation according to the first embodiment will be described with reference to FIGS. 5 and 6.

  First, parameters are set in step S1 of FIG. First, the wireless communication unit 110 of the control target device 100 requests the mobile terminal device 200 to transmit device data of the mobile terminal device 200 (S1-1). In the mobile terminal device 200, the wireless communication unit 210 receives the request (S1-2), reads the device data of the mobile terminal device 200 stored in the mobile terminal device device data storage unit 220, and the wireless communication unit 110 (S1-3). Then, the wireless communication unit 110 receives the device data of the mobile terminal device 200 from the wireless communication unit 210 and stores it in the mobile terminal device device data storage unit 132 (S1-4).

  Next, the server communication unit 120, the device data of the control target device 100 stored in the control target device device data storage unit 131, and the device data of the mobile terminal device 200 stored in the mobile terminal device device data storage unit 132 (S1-5), and device data of the control target device 100 and device data of the mobile terminal device 200 are transmitted to the server device 300 (S1-6).

  Next, in the server device 300, the server communication unit 310 receives the device data of the control target device 100 and the device data of the mobile terminal device 200 (these are collectively referred to as “device information”) (S1-7) By comparing the device information with the device data management table stored in the parameter database 320, the parameters (here, the threshold value and the timer reference value) that match the received device information are searched (S1-8). Then, the server communication unit 310 transmits the parameters obtained by the search to the server communication unit 120 of the control target device 100 (S1-9).

  Then, the server communication unit 120 receives the parameters from the server communication unit 310, and stores the threshold value in the threshold storage unit 121 and the timer reference value in the timer reference value storage unit 122 among the received parameters (S1-10). ).

  Next, the server communication unit 120 requests the server device 300 to transmit software information (S1-11). In the server device 300, when the server communication unit 310 receives the request (S1-12), the server communication unit 310 reads the software information from the software information management table stored in the parameter database 320 and transmits the software information to the server communication unit 120 (S1- 13). Then, the server communication unit 120 receives the software information from the server communication unit 310 and stores it in the software information storage unit 123 (S1-14).

  The absence determination unit 140 stores the threshold stored in the threshold storage unit 121 in the threshold setting unit 141, and stores the timer reference value stored in the timer reference value storage unit 122 in the determination time measurement unit 142. As a result, the absence determination process is set (S1-15).

  Next, the process proceeds to step S2 shown in FIG. 6, and the control target device 100 performs the following absence determination process. First, the absence determination unit 140 initializes the timer value of the timer 144 to the initial value 0 (S2-1). Next, the software state determination unit 143 confirms the software information currently being executed in the control target device 100 and measures the addition timer reference value corresponding to the software information stored in the software information storage unit 123 for the determination time. It is added to the timer reference value of the unit 142 (S2-2). Here, when the addition timer reference value is a positive value, the timer reference value increases, but when the addition timer reference value is a negative value, the timer reference value decreases. In this way, the timer reference value is adjusted.

  Next, the received power strength measurement unit 112 measures the received power strength of the signal from the mobile terminal device 200 received by the wireless communication unit 110 (S2-3). Next, the absence determination unit 112 determines whether or not the received power intensity measured by the received power intensity measuring unit 112 is equal to or less than the threshold stored in the threshold setting unit 141 (S2-4), and the received power intensity Is larger than the threshold value, the process returns to step S2-1 to initialize the timer value.

  On the other hand, when the received power intensity is equal to or smaller than the threshold value in step S2-4, the determination time measuring unit 142 activates the timer 144 (S2-5). Next, the determination time measuring unit 142 determines whether or not the timer value of the timer 144 is equal to or greater than the timer reference value (S2-6). If the timer value is equal to or greater than the timer reference value, step S2-11 described later is performed. On the other hand, if the timer value is smaller than the timer reference value, the process proceeds to the following step S2-7.

  In step S2-7, the software state determination unit 143 confirms the software information currently being executed in the control target device 100 at the time, similarly to step S2-2, and the software stored in the software information storage unit 123 The addition timer reference value corresponding to the information is added to the timer reference value of the determination time measuring unit 142.

  Next, similarly to step S2-3, the received power strength measurement unit 112 measures the received power strength of the signal from the mobile terminal device 200 received by the wireless communication unit 110 (S2-8). Next, the absence determination unit 112 determines whether or not the reception power intensity measured by the reception power intensity measurement unit 112 is equal to or less than the threshold stored in the threshold setting unit 141 (S2-9), and the reception power intensity Is larger than the threshold value, the process returns to step S2-1 to initialize the timer value.

  On the other hand, when the received power intensity is less than or equal to the threshold value in step S2-9, the determination time measurement unit 142 determines whether or not the timer value of the timer 144 is equal to or greater than the timer reference value (S2-10), and the timer value is If the timer value is smaller than the timer reference value, the process returns to step S2-7 described above. On the other hand, if the timer value is equal to or greater than the timer reference value, the determination time measuring unit 142 determines in step S2-11 that the person is away from the seat.

  In step S3, the away processing unit 150 performs predetermined leaving processing on the control target device 100 and ends the processing.

By comparing the received power threshold value with the received power for the received signal from the mobile terminal device, it is possible to appropriately perform the absence determination, and the received power in the short-range wireless communication between the mobile terminal device and the control target device. In the case of automatically performing the leaving process based on the above, it is possible to suppress the occurrence of malfunction by software processing without adding hardware.

  In addition, the parameter includes a timer reference value. When the received power is less than or equal to the received power threshold, a timer based on the timer reference value is started and the received power exceeds the received power threshold before the timer ends. In other words, the execution of the away process is avoided.

Next, the absence determination unit 402 determines whether or not the difference value is equal to or greater than the no-operation time reference value (S5-5). The determination returns to step S5-1. On the other hand, if the difference value is equal to or greater than the no-operation time reference value in step S5-5, in step S5-6, the absence determination unit 402 determines that the user is away.

  In step S6, the away processing unit 150 performs predetermined leaving processing on the control target device 400 and ends the processing.

  According to the first embodiment described above, after a user operation is performed on the control target apparatus 400, a new user operation is performed on the control target apparatus 400 before a predetermined no-operation time reference value elapses.

If the acceleration sensor value is smaller than the walking state recognition level, the predetermined leaving process is not performed. Avoid running.

  Hereinafter, the processing operation according to the third embodiment will be described with reference to FIGS. 13 and 14.

  First, parameters are set in step S7 of FIG. First, the wireless communication unit 110 of the control target device 600 requests the mobile terminal device 700 to transmit device data of the mobile terminal device 700 (S7-1). In the mobile terminal device 700, the wireless communication unit 210 receives the request (S7-2), reads the device data of the mobile terminal device 700 stored in the mobile terminal device device data storage unit 220, and the wireless communication unit 110 (S7-3). Then, the wireless communication unit 110 receives the device data of the mobile terminal device 700 from the wireless communication unit 210 and stores it in the mobile terminal device device data storage unit 132 (S7-4).

  Next, the server communication unit 120, the device data of the control target device 600 stored in the control target device device data storage unit 131, and the device data of the mobile terminal device 700 stored in the mobile terminal device device data storage unit 132 (S7-5), and device data of the control target device 600 and device data of the portable terminal device 700 are transmitted to the server device 800 (S7-6).

  Next, in the server device 800, the server communication unit 310 receives the device data of the control target device 600 and the device data of the portable terminal device 700 (these are collectively referred to as “device information”) (S7-7). By collating the device information with the device data management table stored in the parameter database 801, the parameters (here, the threshold value and the walking state recognition level) suitable for the received device information are searched (S7-8). Then, the server communication unit 310 transmits the parameters obtained by the search to the server communication unit 120 of the control target device 600 (S7-9).

  Then, the server communication unit 120 receives the parameters from the server communication unit 310, and stores the threshold value in the threshold storage unit 121 and the walking state recognition level in the walking state recognition level storage unit 601 among the received parameters (S7). -Ten).

  Then, the absence determination unit 602 stores the threshold stored in the threshold storage unit 121 in the threshold setting unit 141, and the walking state recognition level stored in the walking state recognition level storage unit 601 as the walking state identification unit 603. Is stored, the absence determination process is set (S7-11).

  Next, it progresses to step S8 shown in FIG. 14, and the following absence determination processing is performed. First, the received power strength measurement unit 112 of the control target device 600 measures the received power strength of the signal from the mobile terminal device 700 received by the wireless communication unit 110 (S8-1). Next, the absence determination unit 602 determines whether the received power intensity measured by the received power intensity measuring unit 112 is equal to or less than the threshold stored in the threshold setting unit 141 (S8-2), and the received power intensity Is greater than the threshold, the process returns to step S8-1. On the other hand, if the received power intensity is less than or equal to the threshold, the process proceeds to step S8-3 below.

  In step S8-3, the acceleration sensor control unit 604 sends an activation control signal for the acceleration sensor unit 701 from the wireless communication unit 110 to the portable terminal device 700 to activate the power supply of the acceleration sensor unit 701 of the portable terminal device 700. Send to.

  In the mobile terminal device 700, the wireless communication unit 210 receives the activation control signal and transfers it to the acceleration sensor unit 701 (S8-4). As a result, the power source of the acceleration sensor unit 701 is activated and the acceleration sensor unit 701 starts to operate. Then, the acceleration sensor unit 701 measures the acceleration sensor value in the mobile terminal device 700 (S8-5), the acceleration sensor value obtained by the measurement is transferred to the wireless communication unit 210, and the wireless communication unit 210 converts the acceleration sensor value. Transmission is performed toward the control target device 600 (S8-6).

  In the control target device 600, the acceleration sensor value is received by the wireless communication unit 110 and transferred to the acceleration sensor control unit 604, and the acceleration sensor control unit 604 stores the acceleration sensor value in the walking state identification unit 603 (S8- 7).

  Next, the walking state identification unit 603 determines whether or not the acceleration sensor value stored in step S8-7 is equal to or higher than the walking state recognition level stored in step S7-10 (S8-8). Here, if the acceleration sensor value is smaller than the walking state recognition level, it is determined that the user is not in the walking state, and in step S8-9, the acceleration sensor control unit 604 turns on the acceleration sensor unit 701 of the mobile terminal device 700. In order to stop, a power stop control signal of the acceleration sensor unit 701 is transmitted from the wireless communication unit 110 to the mobile terminal device 700, and then the process returns to step S8-1. In the mobile terminal device 700, the wireless communication unit 210 receives the stop control signal and transfers it to the acceleration sensor unit 701 (S8-10). Thereby, the power supply of the acceleration sensor unit 701 is stopped, and the operation of the acceleration sensor unit 701 is stopped.

  On the other hand, if the acceleration sensor value is greater than or equal to the walking state recognition level in step S8-8, it is determined that the user is in the walking state, and in step S8-11, the absence determination unit 602 determines that the user is away. In step S9, the away processing unit 150 performs predetermined leaving processing on the control target device 600 and ends the processing.

  According to the third embodiment described above, the control target device can accurately identify whether or not the user is in the walking state by comparing the received acceleration sensor value with the walking state recognition level. When it is identified that the user is not in a walking state, execution of the away process can be avoided. Accordingly, even when the user is seated in front of the control target device, the occurrence of malfunction can be suppressed even in a situation where the received power is temporarily reduced due to a change in the surrounding environment.

  Also, the power source of the acceleration sensor of the mobile terminal device is activated only when it is determined that the received power is equal to or less than the threshold value. Thus, since the acceleration sensor of the mobile terminal device is activated only when necessary, the power consumption of the mobile terminal device can be reduced.

  Note that two or more exception processes in the first to third embodiments described above may be combined and executed. For example, after being determined to be away from the seat in the first or second embodiment, the power source of the acceleration sensor of the mobile terminal device is activated as in the third embodiment, and the acceleration sensor value is compared with the walking state recognition level. The absence determination may be performed again based on the comparison result. In this case, even after it is determined to be away from the seat according to the method of Embodiment 1 or 2, it is appropriately identified whether or not the user of the mobile terminal device is in a walking state, and if the user is not in a walking state The execution of the away process can be avoided when it is identified. For this reason, even when the reception power is temporarily lowered due to a change in the surrounding environment when the user is not away, the occurrence of malfunction can be further suppressed.
