Description

The present invention relates to a function restriction system for a portable electronic device that restricts an operation function of a portable electronic device with a wireless communication function brought into the facility by a function control signal generated by a facility-side control device installed in the facility, and The present invention relates to a portable electronic device suitable for use in the function restriction system.

A portable communication terminal such as a mobile phone or PHS which is a portable electronic device is very convenient because a call can be made anywhere as long as radio waves reach the repeater (base station).

On the other hand, if you use it carelessly in a public place such as a train, it will inconvenience others. Also, in public places such as airplanes, laboratories, and hospitals,
There is a risk of causing an abnormal operation of an electronic device such as a measuring device, a control device, or a pacemaker installed in the place.

Therefore, in order to reliably prevent the occurrence of inconveniences such as calls made by portable communication terminals causing trouble for others or radio waves emitted by telephones causing abnormal operation to surrounding electronic devices, A function restriction system has been proposed in which a portable communication terminal brought into the facility is turned off for a predetermined time by a function control signal generated by the installed facility-side control device (see, for example, Patent Document 1).

By adopting such a function restriction system, it is possible to reliably prevent the occurrence of inconvenience due to illegal use due to manner violation or the like.

However, in recent portable communication terminals, in addition to the function as a wireless telephone, application software compatible with a photographing function as a camera, a Web browsing function by Internet connection, a spreadsheet software used in a personal computer, etc. Each company has developed a multi-functional model with various functions, such as an application function for operating the card and a settlement function that can be used as a prepaid card.

In such a multi-functional model, if a uniform regulation for forcibly turning off the power as described in the above-mentioned Patent Document 1 is implemented, there will be no inconvenience to others even if it is used. It becomes unusable and becomes over-regulated.

Therefore, the function control signal generated by the facility-side control device installed in the facility does not turn off the power to the portable communication terminal brought into the facility, but only the functions that require regulation are specified. A function restriction system has been proposed that allows the restriction to be disabled for a limited time, and if there is a reasonable reason, the restriction can be forcibly released by the user's conscious operation of the portable communication terminal or the like. (For example, refer to Patent Document 2).

As in the function restriction system described in Patent Document 2, the power supply itself is not turned off, but only functions that require regulation are restricted, and functions that do not participate in regulation (for example, portable communication terminals) Equipped app functions, etc.) can be activated and the terminal can be used effectively within the limits.

Furthermore, in the case of a portable communication terminal equipped with a photographing function, there are many cases where the photographing function is limited in a public facility or the like. However, the limitations of the shooting function are usually for shooting surrounding objects and others, and are often not subject to regulation when used only for users of portable communication terminals themselves. In the event of an emergency situation where it is desired to communicate the video, if there is a restriction release function described in Patent Document 2, such an emergency situation can be dealt with.
JP 2003-110694 A JP 2004-260796 A

However, as described in Patent Document 2, if a portable communication terminal or the like is equipped with a restriction release function, the restriction can be lifted maliciously and illegally voyeurized or an illegal call can be made. In the conventional system, since it is not possible to easily demonstrate the occurrence of such unauthorized restriction release, there is a problem that it is difficult to reduce unauthorized use due to malicious restriction release.

In addition, in the conventional system, there is no description of a technology that allows a function restricted by a function control signal generated by the facility-side control device to be confirmed at any time by a terminal such as a portable communication terminal. Attempting to activate the restricted function without knowing that it is in the middle, misunderstanding that the device is malfunctioning, or misunderstood that the restriction has been released, There is a risk that the possible functions cannot be used smoothly.

Accordingly, an object of the present invention is to solve the above-described problems, and promote the establishment of a sound environment for using portable electronic devices by reducing the inappropriate use of portable electronic devices due to malicious restriction cancellation in a restricted function area. In addition, it is possible to easily check the functions that have been restricted or the functions that have been lifted, and to make more effective use of the unrestricted functions installed in portable electronic devices. Electronic equipment and its function restriction system.

In order to solve the above-mentioned problems, a portable electronic device function restriction system according to the present invention is a portable electronic device having a wireless communication function brought into a facility by a function control signal generated by a facility-side control device installed in the facility. A function restriction system for a portable electronic device that restricts an operation function of the electronic device for electronic use, wherein the facility-side control device outputs a function restriction signal corresponding to the restricted function, and the portable electronic device receives the received electronic device Based on the function restriction signal, a control unit that restricts the corresponding operation function of the own device, a function control custom unit that can forcibly release the restriction by the function restriction signal,
A history recording unit that records the history of the function limitation of the own device implemented by the function limitation signal and the function control custom unit in a non-rewritable manner (claim 1).

According to the above configuration, the function restriction signal output from the facility-side control device is not a signal for turning on / off the power of the portable electronic device, but a signal according to the function to be restricted. Since it is possible to restrict only the corresponding operation function, a function that does not cause trouble for others even if it is used can be effectively used even in a function restricted area by a function restriction signal.

In addition, functions that need to be regulated due to inconvenience to others and adverse effects on surrounding electronic devices can be performed on the portable electronic device side with respect to the function restriction signal without any special operation by the user of the portable electronic device. The function is automatically limited by the automatic response. Therefore, it is possible to construct a sound use environment of the portable electronic device corresponding to the function-restricted area without burdening the user of the portable electronic device in operation.

In addition, if there is a reasonable reason for the function restricted by the function restriction signal, the restriction can be forcibly canceled by the user of each portable communication terminal etc. by performing a release operation with the function control custom part. The function restriction by the function restriction signal does not impair the convenience of the portable electronic device in an emergency or the like.

In the above configuration, both the function restricted by the function restriction signal and the function released by the user through the operation of the function control custom part are recorded in the history recording part.
If a user unfairly uses a function whose restriction has been canceled by operating the function control custom part without a reasonable reason, check the function restriction history in the history recording part of the portable electronic device. , The occurrence of such an unauthorized restriction release can be easily demonstrated and can be used as evidence for the unauthorized use. In addition, when another person misunderstands that there has been an unauthorized use due to the restriction release, the misunderstanding can be resolved by showing the function restriction history. Therefore, it is possible to prevent unreasonable restriction cancellation by users of portable electronic devices, reduce unauthorized use of portable electronic devices due to malicious restriction cancellation in restricted function areas, and reduce the use environment of sound portable electronic devices. The construction can be promoted.

In addition, it further includes a position information acquisition unit that acquires a position information signal of the portable electronic device,
The history recording unit records the position information acquired by the position information acquisition unit together with the function restriction history and time information in a history storage unit, thereby improving the reliability of the information recorded in the portable electronic device. More collateral becomes possible.

  The position information signal varies depending on the type of signal received. For example, in the signal from the GPS satellite, the position of the portable electronic device is calculated from the IDs, times, and propagation delay information of the plurality of satellites. In a signal from a public radio base station or a signal from a wireless LAN, each ID and signal strength may be treated as position information. Furthermore, the device unique ID included in the near field communication signal of the facility side control device or the like may be used. Moreover, it is preferable that the time information set in each apparatus is included.

This is because the time of the clock of the portable electronic device is insufficient to ensure the reliability of the information recorded in the portable electronic device, which can be freely changed by the user. (Claim 2)
Further, the function restriction signal is a restriction mode signal set according to a combination of restricted operation functions, and the control unit of the portable electronic device is a function that defines an operation function to be restricted for each of various restriction modes. A restriction table is held, and the corresponding operation function is restricted based on the restriction mode specified in the function restriction signal.

With this configuration, for example, the function limit signal output from the facility-side control device can be a signal with a simple configuration regardless of the number of functions to be limited, even when there are a large number of operation functions to be limited. As a result, it is possible to simplify the configuration of the facility-side control device that outputs the function restriction signal, and to reduce the size and cost.

In addition, the downsizing of the facility-side control device makes it easy to secure a place where the facility-side control device is installed. For example, a suspension ring in a train or a bus, a part of a vehicle seat, a station ticket gate device, etc. It becomes easy to spread the system, for example, by embedding a facility-side control device in a department.

  Moreover, the portable electronic device which concerns on this invention is a portable electronic device which can be used for the function restriction | limiting system of the portable electronic device as described in any one of Claims 1-3, Comprising: Operation | movement restriction | limiting is carried out. A display unit for displaying the function is provided (claim 4).

According to the above configuration, the function being restricted or the function for which the restriction is released can be easily confirmed on the display unit. Then, by confirming the function being restricted by the display unit, for example, without knowing that the function is being restricted, an attempt to operate the function being restricted and misunderstanding that it is a device failure Can be prevented. In addition, it is possible to prevent the occurrence of inconveniences such as the fact that the functions that can be used cannot be smoothly utilized due to the fact that the restrictions are lifted, even though they are mistakenly regarded as being restricted.

Therefore, it is possible to more effectively utilize the various functions that are installed in the portable electronic device.

The function restriction history recorded in the history recording unit can be displayed on the display unit (claim 5).

  With such a configuration, it is possible to easily check the history of function restrictions.

Further, it is provided with a custom restriction mode in which an arbitrary operation function is placed in a restricted state by an input setting on its own device, regardless of the function restriction signal generated by the facility-side control device (claim) Item 6).

In such a configuration, even if the facility-side control device is not installed, if it is considered necessary to restrict some functions of the portable electronic device, the user will select the custom restriction mode at the appropriate time. By doing so, it is possible to maintain the portable electronic device in an operating state that does not inconvenience others.

In the portable electronic device and the function restriction system thereof according to the present invention, the function restriction signal output from the facility-side control device is not a signal for turning on / off the power of the portable electronic device, but according to the function to be restricted. Because it is possible to restrict only the applicable operation function on the portable electronic device side with the signal, the function that does not disturb other people even if it is used should be used effectively even within the function restriction area by the function restriction signal. Can do.

In addition, functions that need to be regulated due to inconvenience to others and adverse effects on surrounding electronic devices can be performed on the portable electronic device side with respect to the function restriction signal without any special operation by the user of the portable electronic device. The function is automatically limited by the automatic response. Therefore, it is possible to construct a sound use environment of the portable electronic device corresponding to the function-restricted area without burdening the user of the portable electronic device in operation.

In addition, if there is a reasonable reason for the function restricted by the function restriction signal, the restriction can be forcibly canceled by the user of each portable communication terminal etc. by performing a release operation with the function control custom part. The function restriction by the function restriction signal does not impair the convenience of the portable electronic device in an emergency or the like.

In the above configuration, both the function restricted by the function restriction signal and the function released by the user through the operation of the function control custom part are recorded in the history recording part.
If a user unfairly uses a function whose restriction has been canceled by operating the function control custom part without a reasonable reason, check the function restriction history in the history recording part of the portable electronic device. , The occurrence of such an unauthorized restriction release can be easily demonstrated and can be used as evidence for the unauthorized use.

In addition, when another person misunderstands that there has been an unauthorized use due to the restriction release, the misunderstanding can be resolved by showing the function restriction history. Therefore, it is possible to prevent unreasonable restriction cancellation by users of portable electronic devices, reduce unauthorized use of portable electronic devices due to malicious restriction cancellation in restricted function areas, and reduce the use environment of sound portable electronic devices. The construction can be promoted.

  FIG. 6 is a second schematic configuration diagram of the function restriction system for a portable electronic device according to the embodiment of the present invention. In the control unit 36 of the portable electronic device 5 of FIG. In addition, it is a configuration example of a function restriction system in which position information, time information, and a function restriction history are associated and recorded in a history storage unit.

  The position information signal 8 differs depending on the type of signal received. For example, in the signal from the GPS satellite 60, the position of the portable electronic device 5 is calculated from the IDs and positions of a plurality of satellites and propagation delay information. In the signal from the public wireless base station 50 and the signal from the wireless LAN 70, each ID and signal strength may be treated as position information. Furthermore, the device unique ID included in the near field communication signal of the facility control device 3 may be used. Moreover, it is preferable that the time information set in each apparatus is included.

In FIG. 3, the restriction mode shown in the restriction mode column 21 g is set by the user for the company's own conference room. In the facility where the facility-side control device 3 is not installed, the user's manners, etc. This is effective when restricting functions.

Based on instructions from the operation time control unit 42 and the function control custom unit 44, the function control unit 43 stops the operation of the functions that are restricted. In addition, when a release signal is received from the operation time control unit 42 and the function control unit 43, the restriction is released based on the release signal, and the restricted function can be used.

In the case of the portable electronic device 5 of the present embodiment, the function whose operation is restricted by an instruction from the operation time control unit 42 or the function control custom unit 44 is in a form according to the function restriction table 20, and the display unit 34 Can be displayed.

That is, the display unit 34 that displays a communication state or the like functions as a display unit that displays a function whose operation is restricted.

FIG. 4 shows a state in which the function whose operation is controlled by the function restriction signal 7 from the facility control device 3 installed in a hospital or the like is displayed on the display unit 34. From the display on the display unit 34, it can be easily confirmed that all functions other than the camera photographing by the photographing function unit 32h are restricted in the hospital.

Further, in the portable electronic device 5 of the present embodiment, the function restriction history recorded in the history recording unit 46 can be displayed on the display unit 34.

FIG. 5 shows a state in which the function restriction recorded in the history recording unit 46 is displayed on the display unit 34.

The history recording unit 46 preferably has a capacity capable of storing the restriction history and the restriction release history received within at least one week. If possible, the history recording unit 46 may have a capacity for storing the restriction history and the restriction release history over a longer period. It is desirable to ensure.

According to the function restriction system 1 described above, the function restriction signal 7 output from the facility-side control device 3 is not a signal for turning the power of the portable electronic device 5 on and off, but according to the function to be restricted. Since it is possible to limit only the corresponding operation function on the portable electronic device 5 side with the signal,
Functions that do not cause trouble for others even if they are used can be used effectively even within the function restriction area by the function restriction signal 7.

In addition, functions that need to be regulated due to inconvenience to others and adverse effects on surrounding electronic devices can be performed by the portable electronic device 5 with respect to the function restriction signal 7 without any special operation by the user. The function is automatically limited by the automatic response on the device 5 side. Therefore, a sound use environment of the portable electronic device 5 corresponding to the function-restricted area can be constructed without imposing a burden on the operation of the user of the portable electronic device 5.

In addition, the functions restricted by the function restriction signal 7 can be forcibly released by the user of each portable electronic device 5 by using the function control custom unit 44 when there is a reasonable reason. Therefore, the convenience of the portable electronic device 5 in an emergency or the like is not impaired by the function restriction by the function restriction signal 7.

In the function restriction system 1 of the above embodiment, both the function restricted by the function restriction signal 7 and the function released by the user through the operation of the function control custom unit 44 are stored in the history recording unit 46. Therefore, if the user unfairly uses a function whose restriction is released by operating the function control custom unit 44 without a reasonable reason (for example, a train whose camera shooting is restricted by the function restriction signal 7). When the restriction on the photographing function unit 32h is forcibly released and the sneak shot or the like is performed inside), the history recording unit 46 of the portable electronic device 5 is used.
By checking the function restriction history of, you can easily demonstrate the occurrence of such unfair restrictions,
Can be used as evidence for illegal use. Conversely, when another person misunderstands that there has been an unauthorized use due to restriction release, the misunderstanding can be resolved by showing the function restriction history. Accordingly, unreasonable restriction cancellation by the user of the portable electronic device 5 is suppressed, and unauthorized use of the portable electronic device 5 due to malicious restriction release in a function-restricted area is reduced. The construction of the usage environment can be promoted.

Furthermore, in the case of the function restriction system 1 of the present embodiment, the function restriction signal 7 is a restriction mode signal set according to the combination of operation functions to be restricted.

In addition, the control unit 36 of the portable electronic device 5 has a function restriction table that defines operation functions to be restricted for each of various restriction modes, and based on the restriction mode specified in the function restriction signal 7.
Restrict applicable operating functions.

In such a configuration, for example, the facility-side control device 3 can set the function limit signal 7 to be output to a signal having a simple configuration regardless of the number of functions to be limited even when there are a large number of operation functions to be limited. As a result, the configuration of the facility-side control device 3 that outputs the function restriction signal 7 can be simplified,
It is possible to reduce the size and cost.

Further, by downsizing the facility-side control device 3, it is easy to secure a place where the facility-side control device 3 is installed. For example, a suspension ring in a train or a bus, a part of a vehicle seat, a ticket gate device at a station It becomes easy to promote the spread of the system by embedding the facility-side control device 3 in a small space such as a part of the system.

In addition to the above, the installation side of the facility-side control device 3 includes a part of a door serving as an entrance / exit of the facility, a periphery of a billboard of a store (shop), a road surface or a wall of a facility passage, etc. be able to.

In addition, since the portable electronic device 5 according to the above-described embodiment includes the display unit 34 that displays the function whose operation is restricted, the function that is being restricted or the function that is released from the restriction is easily displayed on the display unit 34. Can be confirmed. Then, by confirming the function being restricted by the display unit 34, for example, without knowing that the function is being restricted, an attempt is made to activate the function being restricted, and it is misunderstood as a malfunction of the device. Occurrence can be prevented. In addition, it is possible to prevent the occurrence of inconveniences such as the fact that the functions that can be used cannot be smoothly utilized due to the fact that the restrictions are lifted, even though they are mistakenly regarded as being restricted. Therefore, it is possible to more effectively utilize the various functions that are installed in the portable electronic device 5.

In addition, since the portable electronic device 5 according to the above embodiment can display the function restriction history recorded in the history recording unit 46 on the display unit 34, the function restriction history can be easily confirmed.
