  FIG. 1 shows the configuration of a radio detection / mobile phone 1 according to the first embodiment of the present invention. The wireless device detection / mobile phone 1 is carried by a security guard and used for performing duties. The wireless device detection / mobile phone 1 includes a wireless communication unit 10 and a wireless device detection unit 20 housed in the same case. The wireless communication unit 10 has a function as a mobile phone and performs wireless communication with a base station of the mobile phone system. The radio detection unit 20 detects a radio other than the radio detection / cell phone 1.

  The wireless communication unit 10 includes a user interface unit 12, a control unit 14, a wireless unit 16, and a transmission / reception antenna 18. The user interface unit 12 includes a touch panel, a display, a receiver, a microphone, a speaker, an earphone jack, a vibrator, a communication connector, and the like. In the user interface unit 12, an operation for operating the wireless device detection / mobile phone 1 is performed by the user. The user interface unit 12 outputs operation information corresponding to a user operation to the control unit 14.

  The control unit 14 controls the user interface unit 12 and the wireless unit 16 based on the operation information. This control includes control of outgoing calls, incoming calls, telephone calls, transmission / reception of e-mails, browsing of websites on the Internet, and the like.

  In this control, the control unit 14 communicates with the base station via the radio unit 16 and the transmission / reception antenna 18 to access the line of the mobile phone system. That is, the control unit 14 outputs a baseband signal including information to be transmitted to the base station to the radio unit 16. The radio unit 16 converts the signal output from the control unit 14 into a radio signal and transmits the radio signal from the transmission / reception antenna 18 to the base station. The radio unit 16 converts a radio signal transmitted from the base station and received by the transmission / reception antenna 18 into a baseband signal and outputs the signal to the control unit 14.

  In addition, when performing wireless communication with the base station, the control unit 14 depends on the communication method of the mobile phone system to which the base station belongs, such as a frequency multiple access method, a time division multiple access method, and a code division multiple access method. The radio unit 16 is controlled to set the frequency of the radio signal, the time slot in which the radio signal is transmitted and received, and the like.

  In addition, since the wireless device detection / cell phone 1 is used by a security guard in his / her duties, the control unit 14 can browse a website on the Internet, send an e-mail to a specific address, and a specific phone number. It may be set to prohibit calls and the like.

  The wireless device detection unit 20 includes a radio wave detection unit 22, a reception antenna 24, and a reception unit 26. The radio detection unit 20 controls the radio communication unit 10 in a state suitable for detecting radio waves transmitted from other radio units, and then detects radio waves transmitted by other radio units. In the present embodiment, a state suitable for detecting radio waves transmitted from other wireless devices refers to a state in which wireless signals are not transmitted by the wireless unit 16.

  The radio wave detection unit 22 includes a transmission stop unit 28, a radio wave detection / determination unit 30, and a warning command unit 32. The radio wave detection unit 22 may be configured by a processor that operates according to a program read by itself. In this case, the functions of the transmission stop unit 28, the radio wave detection / determination unit 30, and the warning command unit 32 are realized in the radio wave detection unit 22 by executing the program. The radio wave detection unit 22 may be integrated with the control unit 14 in the wireless communication unit 10.

  The transmission stop unit 28 controls the control unit 14 for a predetermined stop time every predetermined interval time to place the radio unit 16 in a stopped state. Here, the process of setting the wireless unit 16 to the stop state includes the process of stopping the transmission of the wireless signal when the wireless unit 16 is transmitting the wireless signal, and the wireless unit 16 is wireless in the operation as a mobile phone. Even if it is necessary to transmit a signal, a process of not transmitting a radio signal is included. The interval time and the stop time are determined as a time that does not hinder the function of the wireless communication unit 10 as a mobile phone. Further, in addition to setting the radio unit 16 in a stopped state at every predetermined interval time, control for setting the radio unit 16 in a stopped state may be executed based on a predetermined schedule without being limited to every equal interval time.

  The radio wave detection / determination unit 30 detects radio waves via the reception antenna 24 and the reception unit 26 during the above-described stop time, and determines whether there is another wireless device based on the detected radio waves. To do. More specifically, the following processing is executed.

  The radio wave detection / determination unit 30 sets the reception frequency of the reception unit 26. This reception frequency is a frequency included in a frequency band used in any mobile phone system. As a result, the reception unit 26 receives and detects the radio wave at the reception frequency via the reception antenna 24. Then, a detection signal for the received radio wave is output to the radio wave detection unit 22.

  The radio wave detection / determination unit 30 determines that another wireless device is present when the intensity of the detection signal exceeds the determination threshold or is equal to or higher than the determination threshold. Here, the determination threshold value is determined based on a value that the intensity of the detection signal can take when another wireless device is within a predetermined distance range from the wireless device detection / mobile phone 1. This distance range is, for example, a radius of 3 m or less, more preferably a radius of 1 m or less. That is, the determination threshold is set so that it is difficult to detect radio waves from a wireless device held by another person outside the predetermined distance range from the guard.

  In addition, regarding the determination that another radio is present, a condition is added that the time when the intensity of the detection signal exceeds the determination threshold exceeds the predetermined determination time, or is equal to or longer than the predetermined determination time. May be. As a result, erroneous determination due to noise generated from an electrical device that is not a wireless device is avoided.

  Also, depending on the communication method employed by the wireless device, the intensity of radio waves emitted from the wireless device varies. For example, in the case of a wireless device employing a time division multiple access method, radio waves are emitted only in a prescribed time slot, and transmission and transmission stop are repeated within a short time. Therefore, the determination of the intensity of the detection signal is performed by determining the time average value of the detection signal (average value within a certain time period in the past), a signal obtained by subjecting the detection signal to a low-pass filter process having an integration effect, etc. You may go by.

  The radio wave detection / determination unit 30 repeatedly changes the reception frequency set for the reception unit 26 within a predetermined frequency range, and determines whether there is another wireless device for each reception frequency. This frequency range is, for example, a frequency range used in any mobile phone system.

  When the radio wave detection / determination unit 30 determines that another wireless device is present, that is, when another wireless device is detected, the warning command unit 32 controls the control unit 14 to the wireless communication unit 10. Perform warning processing. This warning process is a process for dealing with a case where another wireless device is detected, such as a warning operation for alerting a security guard who has a wireless device detection / cell phone 1 or a security guard's management organization. There is contact etc.

  The warning operation includes, for example, a process of emitting a warning sound from a speaker of the user interface unit 12, a process of operating a vibrator of the user interface unit 12, and a process of displaying a warning message on the display. In addition, the contact of the guard to the management organization includes, for example, processing of sending an e-mail to the management organization or making a telephone contact to the management organization. Security guards perform their duties in buildings at night or in patrol cars, and there are many people who use radio equipment such as mobile phones other than security guards. The personnel of the management organization that has received the notification based on the warning operation may confirm the work schedule of the security guard, and if there is a high possibility that there is no person other than the security guard, the security staff may be inquired.

  According to such a configuration and processing, when there is a wireless device such as a mobile phone in the vicinity of the wireless device detection / mobile phone 1, the wireless device is detected by the radio wave detection / determination unit 30. Then, the wireless communication unit 10 executes a warning process under the control of the warning command unit 32. As a result, when the mobile phone privately owned by the security guard is turned on, a warning is given to the security guard, a notification is made to the management organization, and the like. Therefore, it becomes easy to crack down on the use of the mobile phone privately held by the security guard. The determination threshold for the intensity of the detection signal is determined in consideration of the distance to other radio devices. Therefore, it is difficult to detect radio waves from wireless devices such as mobile phones possessed by persons other than security guards.
