Japanese Patent Laying-Open No. 2004-247847 (FIG. 1) JP 2001-313696 A (FIGS. 2 and 3)

  By the way, in the case of the gas leak information notification system described in the above-mentioned Japanese Patent Application Laid-Open No. 2004-247847, the gas leak is detected only by the gas leak detector installed in the system user's home. In the case of this gas leak information notification system, the notification destination of the gas leak information is limited to each user of the system. On the other hand, the occurrence of gas leakage does not necessarily occur only at home, but can occur even when the user is away from home. Further, the user may encounter not only a so-called gas leakage accident but also an accident caused by a toxic gas at the time of a fire or an accident caused by a toxic gas generated by a natural phenomenon such as volcanic gas. . However, in the above-described gas leak information notification system described in Japanese Patent Application Laid-Open No. 2004-247847, it is impossible to cope with gas leaks that these users may encounter on the go, and from the viewpoint of protecting human lives. There are many problems. Furthermore, the gas leak detector described in this publication is designed to detect only gas leaks for specific gases, such as so-called city gas and propane gas. It cannot cope with the various toxic gases that are generated.

  In the case of a mobile phone with an alcohol detection function described in Japanese Patent Laid-Open No. 2001-313696 described above, the sensor detection function specializes in detecting an alcohol odor component contained in a user's bad breath. Components other than the components cannot be detected. In addition, when the user of the mobile phone is a young user who is originally prohibited from drinking alcohol, the sensor and the alcohol detection function become unnecessary.

  In addition, in recent years, many people are concerned about not only alcohol odor but also their own bad breath, body odor, cigarette odor, and other odors. Equipment that can easily detect these various odors at any location. The appearance is awaited.

  The present invention has been proposed in view of such circumstances, and can detect a gas leak even when the user is out of the office, not only by a specific gas such as city gas or propane gas, but also by a fire or a natural phenomenon. It can detect the generation of various gases that are dangerous to human life, such as toxic gas, and can easily detect not only alcohol odor but also various odors such as bad breath, body odor and cigarette odor at any place. An object of the present invention is to provide a portable communication terminal.

  The mobile communication terminal of the present invention includes a communication unit for connecting to a predetermined communication network, a notification unit for performing notification that can be recognized by a user, a position acquisition unit for acquiring a current position, and a plurality of switchable settings. When the gas detection unit having the gas detection function and the gas component amount detected by the gas detection unit exceed the threshold, the user is notified through the notification unit, and the predetermined gas detection information and the current position By having a control unit that automatically reports information to a pre-registered destination through the communication unit, the above-described problems are solved.

  That is, according to the present invention, the gas detection unit is mounted on the portable communication terminal. Further, according to the present invention, since the gas detection unit has a plurality of gas detection functions that can be switched, various gases and odors can be detected by switching the gas detection function.

  In the present invention, since the gas detector is mounted on the portable mobile communication terminal, it is possible to detect gas leaks and toxic gases that are dangerous to human life even when the user is away from home, The gas detector has multiple gas detection functions that can be switched, so it can detect not only city gas and propane gas, but also toxic gases such as volcanic gas, and various other odors such as alcohol odor, bad breath, and body odor. Odor can be easily detected.

  Hereinafter, an embodiment of a mobile communication terminal of the present invention will be described with reference to the drawings.

  In the present embodiment, a mobile phone terminal is cited as an example of the mobile communication terminal of the present invention. Of course, the content described here is merely an example, and it goes without saying that the present invention is not limited to this example. Yes.

[Gas detection flow]
3 and 4 show a flowchart of processing at the time of gas detection in the cellular phone terminal 1 of the present embodiment. 3 and 4 are processes mainly performed by the control unit 20 based on a program stored in the memory unit 25.

  First, prior to the execution of the processes shown in FIGS. 3 and 4, the user sets the usage method (that is, the detection mode) of the gas sensor 37 by selecting a menu of the mobile phone terminal or the like. It is assumed that the automatic notification mode for determining whether or not to notify the gas detection information is set, and that the contact information of these institutions is also set when performing the automatic notification.

  In FIG. 3, when an instruction to start a gas detection operation is input from the user via the operation unit 24 (step S <b> 1), the control unit 20 sets a detection mode set by the user in advance as the process of step S <b> 2. For example, it is determined whether or not it is a mode for automatically detecting various toxic gases generated by natural phenomena such as city gas, propane gas, and volcanic gas, that is, a mode relating to human life (denoted as an emergency mode). When it is determined in step S2 that the emergency mode is not set, the control unit 20 proceeds to another mode process in step S10 described later. On the other hand, when it is determined that the emergency mode is selected, the control unit 20 proceeds to step S3.

  When the process proceeds to step S3, the control unit 20 extracts information necessary for operating the gas sensor 37 with response characteristics corresponding to the mode from the memory unit 25 and sends the information to the gas sensor control unit 26, and the gas sensor control unit 36 By controlling the response characteristics of the gas sensor 37, the detection mode of the gas sensor 37 is set to a mode (that is, response characteristics) for detecting gas components related to human life such as city gas, propane gas, and toxic gas. Then, the detection operation (sensing) of the surrounding gas components is performed in the mode.

  Note that the control unit 20 sets the characteristics (detection mode) of the gas sensor 37 within a predetermined time so that all types of gas components such as city gas, propane gas, and other toxic gases can be detected during the sensing. You may make it switch in order. In addition, for example, when it is assumed that a gas leak has occurred in the vicinity of the current position, the control unit 20 has a high possibility that the leaked gas is a city gas or a propane gas. It may be determined based on, for example, gas distribution information provided by a gas company and current position information by GPS, and the setting of the detection mode of the gas sensor 37 may be switched according to the determination result. In other words, the gas distributed from the gas company is generally only city gas or propane gas depending on the region, and from the gas distribution information of the region and the current position information of GPS, Since it is possible to determine whether the gas used in the area is city gas or propane gas, if the detection mode of the gas sensor 37 is set based on the determination result, it can be performed more quickly and accurately. Gas leak detection can be performed. Similarly, when it is possible to identify a place where volcanic gas is likely to be generated or a place where other toxic gas is likely to be generated depending on the area, the current position is determined based on the already specified area and GPS current position information. If the setting is switched to the detection mode for detecting a gas that has a high possibility of being generated at, gas generation can be detected more quickly and accurately.

  Next, the control unit 20 advances the processing to step S4, and determines whether or not the gas component amount detected by the sensing in step S3 is equal to or greater than a threshold value determined in advance in the detection mode. Here, the threshold value of the gas component amount is, for example, a value indicating whether or not the detected gas component amount is an amount relating to human life, and is extracted from the memory unit 25. If the control unit 20 determines in step S4 that the detected gas component amount is less than the threshold value, the control unit 20 proceeds to step S8, which will be described later. If it is determined that the value is equal to or greater than the threshold, the process proceeds to step S5.

  When the process proceeds to step S5, the control unit 20 displays a warning image on the display of the display unit 23, outputs a warning sound from a speaker, or uses a vibrator for warning according to the detected component amount, for example. Control is performed such as vibrating or causing the LED to emit light for warning. The warning image may be changed to a different image according to the component amount, and the volume, tone, and sound output pattern of the warning sound may be changed according to the component amount. The vibration intensity and vibration pattern of the vibration may be changed according to the component amount, and the brightness, color, and blinking pattern of the warning light emission may be changed according to the component amount. Thereby, the mobile phone terminal 1 of the present embodiment notifies the user of gas leakage or generation of toxic gas.

  Next, the control unit 20 determines whether or not the automatic notification mode for reporting the gas detection information to the previously registered engine 13 or the like is turned on by the user as the process of step S6. When the control unit 20 determines in step S6 that the automatic notification mode is not set to ON, the control unit 20 proceeds to step S8 described later, and on the other hand, determines that the automatic notification mode is set to ON. Then, the process proceeds to step S7.

  When the processing proceeds to step S7, the control unit 20 automatically sends the gas detection information and current position information to a registered organization 13 such as a fire station, police station, gas company, local government office, or the like registered in advance. To report to. Thereby, the registration organization 13 can know the occurrence of gas leakage and the generation of toxic gas, and can quickly cope with it. In this step S7, the gas detection information may be automatically reported to the nearby mobile phone terminal 2 or the like using short-range wireless communication, or another mobile phone terminal registered in advance by the user or fixed Gas detection information may be automatically reported to a telephone, personal computer, or the like.

  Next, the control unit 20 advances the process to step S8, for example, determines whether or not a gas detection operation end instruction is input from the user via the operation unit 24. In step S9, the state of the mobile phone terminal is changed to the normal reception standby state. On the other hand, if the end instruction is not input, the process returns to step S2.

  In Step S2, if it is determined that the emergency mode is not set and the process proceeds to Step S10, the control unit 10 moves the process to Step S21 in FIG.

  If it progresses to the process of step S21 of FIG. 4, the control part 20 will confirm which detection mode is set in advance by the user. That is, in this case, the control unit 20 detects a detection mode other than the emergency mode described above, for example, a detection mode for detecting odors such as various components included in bad breath and body odor, cigarette odor, cooking odor, dust, dust, pollen, etc. The detection mode for detecting the fine particles is confirmed.

  The setting of the detection mode other than the emergency mode described above is, for example, automatically switched by the control unit 20 based on information such as current time information, user schedule book data, and current season. Also good. That is, for example, when it is found from the user's schedule book data that the current time zone is, for example, after a drinking party, the control unit 20 sets the detection mode of the gas sensor 37 to a mode for detecting an alcohol odor component. Set the mode to detect cooking odors, or set the detection mode of the gas sensor 37 to the mode to detect cigarette odor, for example, when the current time zone is rest time and there is a high possibility of smoking For example, when it is known that the current season is a season in which, for example, in early spring, there is a lot of scattering of cedar pollen, the detection mode of the gas sensor 37 is set to a mode for detecting fine particles such as pollen. You can go. Thus, if the mode setting of the gas sensor 37 is switched according to the user's schedule, time zone, and current season, the odor component can be detected more quickly and accurately.

  Next, control part 20 advances processing to Step S22, and after determining the threshold of the gas ingredient (odor ingredient) detected with gas sensor 37 according to the detection mode checked at Step S21, at Step S23 The detection operation (sensing) by the gas sensor 27 is executed. Here, the threshold value of the gas component amount is, for example, whether or not the odor detected in each detection mode such as bad breath, body odor, cigarette odor, cooking odor is strong, or fine particles such as dust, dust, pollen, etc. Is a value indicating whether or not there are many, and is extracted from the memory unit 25.

  Next, the control unit 20 advances the processing to step S24, and determines whether or not the gas component amount detected by the sensing in step S23 is equal to or greater than the threshold value determined in step S22.

  When the control unit 20 determines in step S24 that the gas component amount is less than the threshold value, the control unit 20 proceeds to step S26, and there is no odor on the display of the display unit 23, for example. Is displayed. On the other hand, if it is determined that the gas component amount is equal to or greater than the threshold, the control unit 20 proceeds to step S25, and displays a warning image on the display of the display unit 23, for example, according to the detected component amount, Control is performed such as outputting a warning sound from the speaker, vibrating the vibrator with a predetermined warning vibration pattern, or causing the LED to emit light with a predetermined warning color or blinking pattern. Thereby, the mobile phone terminal 1 of the present embodiment notifies the user whether or not there is an odor. In addition, when the mobile phone terminal of the present embodiment detects bad breath, the user's health check is automatically performed based on the odor component and the component amount of the bad breath, and the result of the check is displayed on a display, for example. It is also possible.

  When the process shown in FIG. 4 ends, the control unit 20 advances the process to step S8 in FIG.

[Summary]
As described above, according to the present embodiment, information on gas leakage and generation of toxic gas around the user is detected using a mobile phone terminal that everyone has, and the gas detection information is obtained. In addition to notifying each user himself / herself, the vast network of mobile phone networks is used to automatically report to fire departments, police stations, gas companies, local governments, and other mobile phone terminals in the vicinity. It is possible to report to the user by short-range wireless communication. Therefore, according to the present embodiment, in the event of a gas leak accident or generation of toxic gas, the time until an ambulance or the like is dispatched can be shortened, and gas leakage or generation of toxic gas can be prevented. It is possible to notify directly to the individual individuals around.

  In addition, according to the present embodiment, since the gas sensor is mounted on the mobile phone terminal, not only in a building such as a house or a building, but also in a place where a gas detection device cannot be installed, It can detect toxic gas generated by such natural phenomenon, and can use existing mobile phone network as it is, so it can respond without building a special infrastructure, and it can detect gas leakage and generation of toxic gas The range can be greatly expanded.

  In addition, since the mobile phone terminal of this embodiment can switch the detection mode of the gas sensor, it is usually a bad breath checker, a body odor checker, a simple alcohol checker, a cigarette smell checker, or a dust or dust sensor, a pollen sensor. As it is not specialized for a single function like a conventional alcohol detector, it can be used in a variety of ways that are closer to life, and with the addition of a new function called odor detection. It is also possible to tick the user's playfulness.

  The above description of the embodiment is an example of the present invention. For this reason, the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made according to the design or the like as long as the technical idea according to the present invention is not deviated.

  In the present embodiment, an example in which the gas sensor is mounted on the mobile phone terminal main body has been described. However, for example, when the mobile phone terminal is put in a bag or in a pocket, it may be impossible to immediately detect gas. In order to cope with such a case, for example, a gas sensor is provided in a controller unit of an earphone attached to a mobile phone terminal having a music player function, and the gas sensor of the controller unit is used when the earphone is used. Gas detection may be performed by the above.

  In addition, the portable information terminal of the present invention is not limited to a portable telephone terminal, and can be applied to various portable information terminals such as PDA (Personal Digital (Data) Assistants) having a communication function.
