[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a portable terminal device, and more particularly to a portable terminal device in which transmission in a place where transmission of electromagnetic waves is restricted by a cellular phone or the like is automatically prohibited.
[0002]
[Prior art]
In trains, hospitals, etc., portable terminal devices that transmit electromagnetic waves, such as mobile phones, have a considerably high transmission output, which may cause a malfunction of medical devices such as pacemakers. It is calling as a manner to turn off the power. However, the current portable terminal device may be forgotten to be turned off because the user can only turn it off manually.
[0003]
The use of a portable terminal device such as a cellular phone is dependent on the manners of the user of the portable terminal device, for example, because it is related to the life of the patient in a hospital and may interfere with the operation in a passenger aircraft. A passive attitude may not be enough. In addition, when there is an incoming call in a concert hall or the like, the atmosphere is destroyed. Therefore, in a specific place as described above, devices and systems that are forcibly disabled even when the portable terminal device is turned on are disclosed in, for example, Japanese Patent Laid-Open Nos. 9-275588 and 11 -98564 and JP-A-11-308675.
[0004]
In Japanese Patent Laid-Open No. 9-275588, a restriction setting device that transmits a restriction electromagnetic wave is installed in a restriction area within a cover area of a base station, and the mobile terminal device further includes a receiving unit that receives the restriction electromagnetic wave, Function stop means for stopping the transmission / reception function of the mobile terminal device when the terminal device receives the restriction electromagnetic wave from the restriction setting device is provided. Thereby, when the mobile terminal device exists in the restricted area, communication by the mobile terminal device cannot be performed.
[0005]
Japanese Patent Application Laid-Open No. 11-98564 discloses a mobile phone use prevention device installed in a specific facility or place, and receives a call control signal transmitted from the mobile phone and identifies a subscriber from this signal. The number is decoded and the subscriber identification number is notified to the mobile phone base station. In the mobile phone base station, a call in progress is interrupted by the notified subscriber identification number, and guidance is given by voice or the like. As a result, it is possible to warn the user of the mobile phone who is making a call that the call is being made in the restricted area, and the user who hears this warning does not cause any trouble by turning off the power. Can be.
[0006]
Further, in Japanese Patent Application Laid-Open No. 11-308675, a wireless base device is installed at a predetermined position in a medical facility, an airplane, a train, etc., and a restriction detection circuit for detecting a restriction notification signal issued from the wireless base device is carried. When a restriction notification signal is detected by being provided in the telephone, the power is turned off or transmission is automatically stopped according to the contents of the restriction notification information. Thereby, it is possible to disable the communication of the mobile phone at a specific location.
[0007]
[Problems to be solved by the invention]
However, according to the conventional portable terminal device, the regulation of use in a specific place is based on the principle that the user who understands manners turns off the power, so the user who ignores the manners talks and communicates Or the user forgets to turn off the power and inadvertently leads to the base station.
[0008]
Further, according to each of the above-mentioned publications, it is necessary to install a dedicated device such as a restriction setting device, a mobile phone use prevention device, a wireless base device, etc. in a specific place. Burden is large. Furthermore, for restriction setting devices and wireless base devices, it is necessary to systematize by providing “reception means + function stop means” and restriction detection circuits on the portable terminal device side. A unified standard is required.
[0009]
Therefore, an object of the present invention is to provide a portable terminal device that can regulate the emission of electromagnetic waves in a specific place independently without depending on the combination with other devices.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a telephone / data communication function for performing telephone or data communication wirelessly with a base station, a function for notifying an incoming call by sound from a speaker or vibration from a vibration generating means, voice, etc. In a portable terminal device including a microphone and a display unit that converts a noise into a noise signal, the noise component received via the antenna has periodicity, or the noise component in the operating atmosphere input from the microphone has periodicity. The periodicity analysis means for determining the use place with certain things and determining whether or not the telephone call / communication evasion area is within the call / communication avoidance area based on the result, and the periodicity analysis means being within the call / communication evasion area when determined, a control means for stopping the transmission of the telephone and data communication function based on this, the control means, the content by the periodicity analysis means Results a delay circuit configured to delay, and wherein Rukoto a control unit for setting a receivable state or normal state based on the comparison result of the determination result by the delayed output of the delay circuit and the periodicity analysis means A portable terminal device is provided.
[0011]
According to this configuration, the periodicity analysis unit analyzes whether the noise component input via the wireless system or the voice system has periodicity, and based on the analysis result, the location of the portable terminal device Is determined to be within the prohibited call or communication avoidance area. The control means stops the transmission of the telephone / data communication function when the output from the periodicity analysis means indicates that it is within the call / communication avoidance area. Thus, control is performed so that electromagnetic waves cannot be automatically radiated (transmitted) in places where use of portable terminal devices is prohibited or restricted, such as in hospitals, airplanes, and trains. Moreover, this control is executed only by the portable terminal device. Therefore, since it is possible to automatically prohibit transmission within the calling / communication avoidance area alone, there is no need for the user to turn off the power, and the portable terminal device can be safely brought into the calling / communication avoidance area. Yes. In addition, since there is no need to systemize with other devices, there is no burden on the facility person or the like in the call / communication avoidance area. In addition, since the emission (transmission) of electromagnetic waves is automatically prohibited within the call / communication avoidance area, the use of the reception function and the additional function can be used without worrying about the surroundings.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
Devices such as motors and vehicles, devices using digital circuits, treatment devices, etc. exist throughout our living space. Some of these devices generate electromagnetic waves. This electromagnetic wave appears as noise when received by a portable terminal device such as a cellular phone equipped with an antenna and a receiving circuit. Some of the electromagnetic waves have a specific periodicity. Some devices that generate such electromagnetic waves are installed (or mounted) in specific places or vehicles.
The present invention is focused on this fact, and based on the received regular noise, the location of the portable terminal device (location where the user is located) is sensed and automatically detected from the portable terminal device. Electromagnetic radiation (transmission) cannot be performed. Moreover, unlike the prior art, it is not necessary to install a restriction setting device and a radio base device and systematize them, and it can be made to function only by a portable terminal device. Hereinafter, the present invention will be specifically described.
[0013]
[First Embodiment]
FIG. 1 shows a portable terminal device according to the present invention. In the following, a mobile phone is used as the portable terminal device. In addition, as a device installed in a specific place or vehicle, a medical device 51 that emits an electromagnetic wave 31 and a motor 52 of a train are assumed. The electromagnetic wave 31 is received by the mobile terminal device 10 when the mobile terminal device 10 approaches the vicinity of the medical device 51 or the motor 52.
The mobile terminal device 10 includes an antenna 1 using a whip antenna or the like, a radio unit 2 for performing transmission / reception with a base station through the antenna 1 and outputting a received electromagnetic wave 31 as a noise signal 32, A periodicity analysis circuit 3 that analyzes the periodicity of the electromagnetic wave 31 output from the wireless unit 2 and outputs an analysis result 33; a control circuit 4 that performs overall control of the mobile terminal device 10; a telephone number and various functions Display unit 5 for displaying mode execution content, speaker melody for ringing melody, voice of the other party during call, playback of recorded message, alarm output, etc., and vibrator for incoming calls when ringing melody is stopped (or simultaneously) For example, a vibration unit 7 (vibration unit generating means) for notifying by vibration and a portable terminal function unit 8 using a nonvolatile memory are provided.
The mobile terminal function unit 8 includes a mobile phone function 9a and a data communication function 9b. The mobile phone function 9a executes transmission / reception with other mobile phones and fixed phones. The data communication function 9b executes connection to the Internet, transmission / reception of electronic mail, and the like.
[0014]
The control circuit 4 puts the mobile terminal function unit 8 into a receivable state or a normal state. Here, the receivable state refers to a state in which a function that does not perform reception of electromagnetic waves and transmission of electromagnetic waves among the functions of the mobile terminal function unit 8 can be used. The normal state refers to a state where all the functions of the mobile terminal function unit 8 can be used.
When it is determined by the periodicity analysis circuit 3 that the portable terminal device 10 is within the call / communication avoidance area, the control circuit 4 sets the portable terminal function unit 8 in a receivable state and calls / communication on the display unit 5. Display a message (message) indicating that it is within the avoidance zone. At the same time, the speaker unit 6 and the vibration unit 7 are driven to notify the user of the mobile terminal device 10.
Further, when the periodicity analysis circuit 3 determines that the mobile terminal device 10 that has been in the call / communication avoidance area has moved out of the call / communication avoidance area, the control circuit 4 puts the mobile terminal function unit 8 in the normal state. At the same time, the display unit 5 displays that it is outside the call / communication avoidance area. At the same time, the speaker unit 6 and the vibration unit 7 are driven to notify the user of the mobile terminal device 10.
[0015]
FIG. 2 shows a detailed configuration of the periodicity analysis circuit 3.
The periodicity analysis circuit 3 determines whether or not the signal analysis unit 11, the place identification unit 12, and a call / communication avoidance area (a call or data communication with transmission should be prohibited or refrained). And a ROM (read-only-memory) 14 in which data of a location including a preset call / communication avoidance area is stored.
In the configuration of FIG. 2, the noise signal 32 input from the wireless unit 2 is detected by the signal analysis unit 11 for the presence or absence of periodicity, and the analysis result 34 is output to the location specifying unit 12. The location specifying unit 12 compares the data stored in the ROM 14 with the analysis result 34 to specify the location, and outputs the location specifying result 35. Based on the location identification result 35 from the location identification unit 12, the power necessary for transmission to the base station, the time, etc., the determination unit 13 determines whether or not it is within the call / communication avoidance area, and the determination result 33 Is output. The determination result 33 is input to the control circuit 4.
[0016]
FIG. 3 shows a detailed configuration of the control circuit 4.
The control circuit 4 includes a delay circuit 42 and a control unit 43. The delay circuit 42 delays the determination result 33 from the periodicity analysis circuit 3 by time t and outputs it to the control unit 43. By adding the delay signal from the delay circuit to the judgment condition, the portable terminal device 10 has moved from outside the call / communication avoidance area into the call / communication avoidance area, and conversely, from within the call / communication avoidance area to outside the call / communication avoidance area. It becomes possible to judge that it has gone out.
[0017]
The control circuit 43 compares the determination result 33 and the delay signal 40, and if they are different (meaning movement in or out of the call / communication avoidance area), the control circuit 36 sends the control signal 36 to the mobile terminal function unit 8. In addition to the output, a control signal 37, a control signal 38, and a control signal 39 are output to the display unit 5, the speaker unit 6, and the vibration unit 7, respectively.
Further, when the control unit 43 receives the input signal 41 by an operation of the user of the mobile terminal device 10, the control unit 43 switches the mobile terminal function unit 8 from the setting of the receivable state (transmission prohibited) to the setting of the normal state, or Conversely, control for switching from the normal state to the receivable state is executed. That is, it is possible to switch between the receivable state and the normal state at the intention of the user. The reason why such a setting is included is that the user is expected to perform the operation after familiarizing manners.
[0018]
FIG. 4 shows processing of the periodicity analysis circuit 3 and the control circuit 4. In the figure, “S” means a step.
The signal analysis unit 11 of the periodicity analysis circuit 3 analyzes the presence / absence of the periodicity of the noise signal 32 from the radio unit 2, and outputs the analysis result 34 to the location specifying unit 12 (S101). The location specifying unit 12 compares the data stored in the ROM 14 with the analysis result 34 to specify the location, and outputs the location specifying result 35 (S102). The determination unit 13 determines whether or not it is within a call / communication avoidance area from the location identification result 35 and the power and time required for transmission to a base station (not shown), and outputs the determination result 33 to the control circuit 4 ( S103).
[0019]
In the control circuit 4, the input determination result 33 is applied to the control unit 43 and the delay circuit 42. The delay circuit 42 delays the determination result 33 by t time to generate a delay signal 40, and applies this delay signal 40 to the control circuit 43. The control circuit 43 compares the determination result 33 with the delay signal 40 (S104, S105). When the determination result 33 indicates that it is within the call / communication avoidance area and the delay signal 40 is not within the call / communication avoidance area (= outside the call / communication avoidance area) (ie, from outside the call / communication avoidance area to within the call / communication avoidance area) ), The control unit 43 outputs a control signal 36 to the mobile terminal function unit 8 (S106). Due to the control signal 36, the mobile terminal function unit 8 enters a receivable state (transmission prohibited state). At the same time, the control circuit 43 outputs control signals 37 to 39 to the display unit 5, the speaker unit 6, and the vibration unit 7 to notify that it is within the call / communication avoidance area (S106).
[0020]
When S101 or S102 determines “no”, or when the determination result 33 is not within the call / communication avoidance area (= out of the call / communication avoidance area) and the delay signal 40 is within the call / communication avoidance area. In other words, the control unit 43 outputs the control signal 36 to put the mobile terminal function unit 8 in the normal state (ie, movement from the inside of the call / communication avoidance area to the outside of the call / communication avoidance area) (S107). With this control signal 36, the mobile terminal function unit 8 enters a normal state. At the same time, the control unit 43 outputs control signals 37 to 39 indicating that it is outside the call / communication avoidance area to the display unit 5, the speaker unit 6, and the vibration unit 7 (S107).
[0021]
As described above, according to the first embodiment, (i) the noise signal 32 has periodicity, (ii) the location is specified, and (iii) the location in use is a call / communication avoidance When it is in the area, functions other than transmission such as reception and additional functions can be used, and transmission cannot be performed. On the other hand, when none of (i) to (iii) is applicable, the use place is regarded as an unregulated place, set to a normal state, and the portable terminal device can be used freely.
[0022]
[Second Embodiment]
Next, a second embodiment of the present invention will be described.
FIG. 5 shows a second embodiment of the present invention.
Here, only the periodicity analysis circuit 30 having a content different from that of the above embodiment will be described. As shown in FIG. 5, the present embodiment is characterized in that a periodicity analysis circuit 30 having a configuration in which a timer unit 16 is provided in front of the signal analysis unit 11 is used. The interval at which the noise signal 32 is captured by the timer unit 16 is set. As a result, the process shown in FIG. 4 is performed at a predetermined interval, so that it is less likely to affect other processes.
[0023]
[Third Embodiment]
Next, a third embodiment of the present invention will be described.
FIG. 6 shows a third embodiment of the present invention. In FIG. 1, illustration of the medical device 51 and the train motor 52 is omitted.
In the present embodiment, the signal input to the periodicity analysis circuit 3 is replaced with the noise signal 32 from the wireless unit 2, the surrounding sound 42 at the place of use is picked up by the microphone 17, and the noise signal 43 is output from the microphone 17. This is input to the periodicity analysis circuit 3. The microphone 17 can also be used as a microphone for calls.
For example, in a train, a running sound or the like is output as a noise signal 43 having a considerable volume and periodicity. Therefore, it can be used instead of the processing of S101 to S103 of FIG.
[0024]
Note that the third embodiment and the second embodiment may be used together with the first embodiment. Alternatively, the third embodiment and the second embodiment can be used in combination.
Further, although a mobile phone has been taken up as a portable terminal device, the present invention is not limited to a mobile phone. For example, a PHS (Personal Handyphone System), a car phone, etc., and further a mobile phone and a PDA (Personal Digital) The present invention can also be applied to a portable terminal device combined with an assistant.
[0025]
【The invention's effect】

In addition, since there is no need to systemize with other devices, there is no burden on the facility person or the like in the call / communication avoidance area. In addition, since the emission (transmission) of electromagnetic waves is automatically prohibited within the call / communication avoidance area, the use of the reception function and additional function can be used without worrying about the surroundings.
