Next, the operation of the wireless communication system according to the present embodiment will be described.
FIG. 3 is a flowchart illustrating an operation when the management apparatus 300 receives an operation request from the control apparatus 200.
When the control device 200 transmits an operation request to the management device 300 via the network, the network communication unit 303 of the management device 300 receives the operation request from the control device 200 (step S1). The operation request transmitted by the control device 200 includes an identification signal of the control device 200. Next, the availability notification unit 302 of the management device 300 determines whether or not the identification information of the control device 200 that is the transmission source of the operation request is stored in the operation inhibition device storage unit 301 (step S2).

  When the operation prohibition device storage unit 301 stores the identification information of the control device 200 (step S2: YES), the availability notification unit 302 indicates the operation prohibition to the control device 200 via the network communication unit 303. Operation availability information is transmitted (step S3). And the network communication part 303 receives the response of operation availability information from the said control apparatus 200 (step S4). Then, the network communication unit 303 records that the operation of the control device 200 is prohibited in the log storage unit 304 (step S5), and ends the process.

  On the other hand, when the operation prohibition device storage unit 301 does not store the identification information of the control device 200 (step S2: NO), the availability notification unit 302 permits the operation to the control device 200 via the network communication unit 303. Is transmitted (step S6). Next, the network communication unit 303 receives an operation prohibition device list request indicating a request for a list of wireless devices 100 whose operation should be prohibited from the control device 200 (step S7). Next, the propriety notifying unit 302 reads a list of wireless devices 100 whose operation should be prohibited from the operation prohibiting device storage unit 301, and transmits the list to the control device 200 via the network communication unit 303 (step S8). Then, the network communication unit 303 records in the log storage unit 304 that the control device 200 has been permitted to operate (step S9).

Thereafter, the network communication unit 303 waits for reception of information from the control device 200 until the control device 200 is powered off (step S10), and the log information is stored in the log storage unit based on the received information. The process of recording in 304 is repeatedly executed (step S11).
The management device 300 executes the above-described process for each control device 200 every time an operation request is received from the control device 200. Further, the operation enable / disable information and the identification information stored in the operation prohibiting device storage unit 301 can be rewritten by the user via an input unit (not shown).

Next, the operation of the control device 200 will be described.
FIG. 4 is a flowchart showing the operation of the control device 200.
When the control device 200 is activated, the network communication unit 201 of the control device 200 transmits an operation request to the management device 300 (step S101). Then, the network communication unit 201 receives the operation availability information from the management device 300, and determines whether or not the operation availability information indicates operation permission (step S102). When the operation availability information indicates that the operation is prohibited (step S102: NO), the network communication unit 201 transmits a response to the operation availability information to the management apparatus 300 (step S103), and ends the process. That is, the control device 200 does not execute the activation process of the wireless device 100 when the management device 300 is designated to prohibit the operation.

  On the other hand, when the operation permission / inhibition information indicates operation permission in step S102 (step S102: YES), an operation prohibited device list request indicating a request for a list of wireless devices 100 that should be prohibited from operation is transmitted to the management device 300 (step S102). S104). Next, when receiving the operation prohibited device list from the management device 300 (step S105), the network communication unit 201 records the operation prohibited device list in the operation prohibited device storage unit 202 (step S106). And the control apparatus 200 repeatedly performs the process of step S107-step S114 shown below until the power supply of the said control apparatus 200 is interrupted | blocked.

  First, the wireless communication unit 204 periodically outputs a notification signal for notifying the wireless device 100 of the presence of the device itself (step S107). When the wireless communication unit 204 outputs a notification signal, the activation unit 203 determines whether the wireless communication unit 204 has received an activation request according to the notification signal from the wireless device 100 (step S108). The activation request transmitted by the wireless device 100 includes an identification signal of the wireless device 100. If the activation unit 203 determines that the activation request has not been received (step S108: NO), the activation unit 203 ends the process for the notification signal transmitted this time, returns to step S107, and waits for the process for the next notification signal. .

  On the other hand, when the activation unit 203 receives the activation request in step S108 (step S108: YES), is the identification information of the wireless device 100 that is the transmission source of the activation request stored in the operation prohibition device storage unit 202? It is determined whether or not (step S109).

  When the operation prohibition device storage unit 202 stores the identification information of the wireless device 100 (step S109: YES), the activation unit 203 transmits an operation prohibition instruction to the wireless device 100 via the wireless communication unit 204. (Step S110). On the other hand, when the operation prohibition device storage unit 202 does not store the identification information of the wireless device 100 (step S109: NO), the activation unit 203 transmits the normal operation time to the wireless device 100 via the wireless communication unit 204. And an activation instruction including information indicating the emergency operation time is transmitted (step S111).

  Next, the wireless communication unit 204 determines whether a response to the transmitted operation prohibition instruction or activation instruction has been received from the wireless device 100 within a predetermined timeout period (step S112). When it is determined that the wireless communication unit 204 has received a response from the wireless device 100 within the timeout period (step S112: YES), the network communication unit 201 confirms that the operation prohibition instruction or the activation instruction has been performed. Is transmitted to the management apparatus 300 (step S113). When the network communication unit 303 of the management device 300 receives the confirmation information, the log information indicates that the operation of the wireless device 100 has been prohibited or the wireless device 100 has been activated by the processing in step S11 described above. Records in the storage unit 304.

  On the other hand, when it is determined that the wireless communication unit 204 has not received a response from the wireless device 100 within the timeout time (step S112: NO), the network communication unit 201 has not responded to the operation prohibition instruction or the activation instruction. The non-delivery information indicating this is transmitted to the management apparatus 300 (step S114). When the network communication unit 303 of the management apparatus 300 receives the non-delivery information, the log storage unit uses, as log information, that the response to the operation prohibition instruction or the activation instruction could not be received by the process of step S11 described above. Record in 304.

  Then, control device 200 ends the process for the notification signal transmitted this time, returns to step S107, and waits for the process for the next notification signal.

Next, the activation operation of the wireless device 100 will be described.
FIG. 5 is a flowchart showing an activation operation of the wireless device 100.
When the wireless device 100 is brought close to the control device 200, the wireless communication unit 101 detects a notification signal output from the control device 200 (step S201). When the wireless communication unit 101 detects the notification signal, the setting unit 102 transmits an activation request to the control device 200 via the wireless communication unit 101 (step S202). Next, the setting unit 102 determines whether the signal received from the control device 200 as a response to the activation request by the wireless communication unit 101 is an activation instruction or an operation prohibition instruction (step S203). When the signal received by the wireless communication unit 101 is an operation prohibition instruction (step S203: NO), the wireless communication unit 101 transmits a response to the operation prohibition instruction to the control device 200 (step S204) and ends the process. To do. At this time, the display unit 104 displays, for example, a character string such as “DOCOMO DINSHINDO DOSATATE” on the display so that the user cannot use the wireless device 100 because the wireless device 100 is registered as an operation prohibition device. Notice.

  On the other hand, when the signal received by the wireless communication unit 101 is an activation instruction (step S203: YES), the wireless communication unit 101 transmits a response to the activation instruction to the control device 200 (step S205). Next, the setting unit 102 records the normal operation time and the emergency operation time included in the activation instruction in the internal memory (step S206). Then, the setting unit 102 instructs the time measuring unit 103 to count down the normal operation time. As a result, the time measuring unit 103 starts counting down the normal operation time (step S207). At this time, the display unit 104 notifies the user of the remaining time of the normal operation time by, for example, displaying a character string such as “Travelous scorpion ** day ** h ** m” on the display.

  Next, the wireless communication unit 101 determines whether or not a notification signal output from the control device 200 has been detected (step S208). If a notification signal is detected (step S208: YES), the wireless communication unit 101 returns to step S202 to activate the notification signal. Make a tivatation request. On the other hand, when the notification signal is not detected in step S208 (step S208: NO), the time measuring unit 103 determines whether or not the normal operation time countdown in step S207 has ended (step S209). When it is determined that the normal operation time has not been counted down (step S209: NO), the time measuring unit 103 continues the determination in steps S208 and S209. On the other hand, when it is determined that the countdown of the normal operation time has ended (step S209: YES), the time measuring unit 103 starts a countdown of the emergency operation time stored in the internal memory (step S210). At this time, the display unit 104 notifies the user of the remaining emergency operation time by, for example, displaying a character string such as “Hinodesano ** h ** m” on the display.

  Next, the wireless communication unit 101 determines whether or not a notification signal output from the control device 200 has been detected (step S211). If a notification signal is detected (step S211: YES), the wireless communication unit 101 returns to step S202, Make a tivatation request. On the other hand, when a notification signal is not detected in step S211 (step S211: NO), the timer 103 determines whether or not the emergency operation time countdown in step S210 has ended (step S212). When it is determined that the countdown of the emergency operation time has not ended (step S212: NO), the time measuring unit 103 continues the determination by steps S211 and S212. On the other hand, when it is determined that the countdown of the emergency operation time has ended (step S212: YES), the time measuring unit 103 ends the process. At this time, the display unit 104 displays, for example, a character string such as “Dosakoyokori Zero Dosateshii” on the display, thereby notifying the user that use is not possible due to the elapse of the maximum operation time.

Next, the voice communication operation of the wireless device 100 will be described.
FIG. 6 is a flowchart showing the voice communication operation of the wireless device 100.
When the wireless device 100 is activated, the wireless communication unit 101 determines whether or not the time measuring unit 103 is counting down the normal operation time or the emergency operation time (step S301). When it is determined that the timing unit 103 is not counting down (step S301: NO), the wireless communication unit 101 ends the process without performing communication. As a result, even when the user loses the wireless device 100 or is stolen, the function of the wireless device 100 is stopped by the lapse of the maximum operation time, so that unauthorized use by others can be prevented.

  On the other hand, when the wireless communication unit 101 determines that the time counting unit 103 is counting down (step S301: YES), the wireless communication unit 101 determines whether the call button is pressed (step S302). When it is determined that the call button has not been pressed (step S302: NO), the wireless communication unit 101 receives a wireless signal from the other wireless device 100 and converts the wireless signal into an audio signal. And the audio | voice output part 106 outputs the audio | voice signal which the wireless transmission part converted from a speaker (step S303).

  On the other hand, when it is determined that the call button is pressed (step S302: YES), the wireless communication unit 101 determines whether the time during which the time counting unit 103 is counting down is a normal operation time or an emergency operation time. (Step S304).

  When the wireless communication unit 101 determines that the time during which the time counting unit 103 is counting down is the normal operation time (step S304: YES), the voice input unit 105 converts the voice signal received by the input into a radio signal. It transmits to the other radio | wireless apparatus 100 (step S305). On the other hand, when the wireless communication unit 101 determines that the time during which the time measuring unit 103 is counting down is an emergency operation time (step S304: NO), the audio signal received by the audio input unit 105 and the warning unit 107 The audio signal superimposed with the warning sound to be output is converted into a radio signal and transmitted to another radio apparatus 100 (step S306).

  The wireless device 100 repeatedly executes the operations in steps S301 to S306 described above until the countdown by the time measuring unit 103 is completed.

  As described above, according to the present embodiment, the warning unit 107 outputs another warning sound to the wireless communication unit 101 when the elapsed time from the time when the activation instruction is received exceeds the normal operation time. A warning sound is emitted from the wireless device 100. As a result, the communication partner can know in advance that the time for which the wireless device 100 can communicate is short, so that when communication with the user of the wireless device 100 is interrupted, this is due to the passage of the usage period. You can know whether it is due to an unexpected situation. Also, the communication partner can prompt the user of the wireless device 100 to update the usage period.

  Further, according to the present embodiment, when the wireless device 100 is designated as an operation prohibition device, the control device 200 transmits an operation prohibition instruction without transmitting an activation instruction to the wireless device 100. To do. Thereby, it is possible to prevent the wireless device 100 whose owner has become unknown due to, for example, theft or loss, and to prevent unauthorized use of the wireless device 100.

  Further, according to the present embodiment, the management apparatus 300 transmits an operation prohibition instruction to the control apparatus 200 when the control apparatus 200 is designated as an operation prohibition apparatus. Thereby, for example, the wireless device 100 stolen by the stolen control device 200 can be prevented from being activated, and unauthorized use of the wireless device 100 and the control device 200 can be prevented.

As described above, the embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to the above, and various design changes and the like can be made without departing from the scope of the present invention. It is possible to
For example, in the present embodiment, the case where the frequency used for voice communication between the radio apparatuses 100 and the frequency used for communication between the radio apparatus 100 and the control apparatus 200 are the same has been described, but the present invention is not limited to this. . For example, when the wireless device 100 includes an RFID (Radio Frequency IDentification) tag, communication between the wireless device 100 and the control device 200 may be performed by RFID.

  Further, in the present embodiment, the wireless communication unit 101 converts the audio signal in which the audio signal received by the audio input unit 105 and the warning sound output from the warning unit 107 are superimposed into a radio signal to convert the other radio signal. Although the case where a warning sound is emitted from another wireless device 100 by transmitting to the device 100 has been described, the present invention is not limited to this. For example, the wireless device 100 may transmit a warning request to another wireless device 100 and the other wireless device 100 may output a warning sound by superimposing the received sound signal. In addition, the wireless communication unit 101 indicates a warning sound input from the warning unit 107 regardless of whether or not the voice input unit 105 accepts an audio signal when the timing unit 103 counts down the emergency operation time. A signal may be transmitted once or periodically to another wireless device 100, and when the other wireless device 100 receives a signal indicating a warning sound, only the warning sound may be output.

  Moreover, although this embodiment demonstrated the case where the control apparatus 200 sets a use period by transmitting normal operation time and emergency operation time to the radio | wireless apparatus 100, it is not restricted to this. For example, the use period may be set by the control device 200 transmitting the normal operation time and the maximum operation time (that is, the sum of the normal operation time and the emergency operation time) to the wireless device 100. Further, the control device 200 may set the use period by transmitting the maximum operation time and the emergency operation time to the wireless device 100. In addition, the normal operation time and the emergency operation time may be stored in advance in the wireless device 100, and the control device 200 may only transmit an activation instruction.

  Moreover, although this embodiment demonstrated the case where the radio | wireless apparatus 100 was provided with the time measuring part 103, it is not restricted to this. When the wireless device 100 does not include the timer 103, for example, the control device 200 counts down the normal operation time and the emergency operation time, and transmits an operation prohibition instruction to the wireless device 100 when the countdown ends. Also good. In this case, the wireless communication unit 204 of the control device 200 needs to output a signal having a strength that reaches a relatively wide range unlike the above-described embodiment. In this case, the device that outputs the operation prohibition instruction is not limited to the control device 200, and may be output from a mobile body such as a base station or a car in each place.

  In the present embodiment, the case has been described in which the timer 103 determines the usage period by counting down the normal operation time and the emergency operation time. However, the present invention is not limited to this. For example, by measuring the elapsed time from the time when the timing unit 103 received the activation instruction, and determining whether the elapsed time has reached the normal operation time and the emergency operation time, the use period can be determined. You may make it do.

  In this embodiment, the case where the operation prohibition device list is received from the management device 300 when the control device 200 is activated has been described. However, the present invention is not limited to this, and the operation prohibition device list is updated while the control device 200 is operating. In this case, the management apparatus 300 may transmit the operation prohibition apparatus list to the control apparatus 200 as appropriate.

In the present embodiment, the operation prohibition storage unit 301 stores and transmits the identification information (list) of the wireless device 100 and the control device 200 that should be prohibited from operating. You may make it memorize | store and transmit the list | wrist of the radio | wireless apparatus 100 and the control apparatus 200 which should be permitted. Further, a list of all the wireless devices 100 and the control device 200 may be held, and prohibition or permission information may be set for each.
In this case, it goes without saying that the control device 200 makes a request for any of the above-described lists instead of the operation prohibited device list request.

  In this embodiment, voice communication is performed between the wireless devices 100. However, the present invention is not limited to this, and the wireless device 100 is provided with a data input unit and a data display unit, and non-voice data communication is performed between the wireless devices 100. May be performed. In this case, a signal indicating a message for prompting the update of the usage period may be used as the warning signal.

  The wireless device 100, the control device 200, and the management device 300 described above have a computer system therein. The operation of each processing unit described above is stored in a computer-readable recording medium in the form of a program, and the above processing is performed by the computer reading and executing this program. Here, the computer-readable recording medium means a magnetic disk, a magneto-optical disk, a CD-ROM, a DVD-ROM, a semiconductor memory, or the like. Alternatively, the computer program may be distributed to the computer via a communication line, and the computer that has received the distribution may execute the program.

  The program may be for realizing a part of the functions described above. Furthermore, what can implement | achieve the function mentioned above in combination with the program already recorded on the computer system, and what is called a difference file (difference program) may be sufficient.
