Description

  The present invention relates to a security method and a security system, and in particular, a security method using a mobile terminal that confirms the safety of a contractor by communicating between a center device operated and managed by a security company and a mobile terminal such as a mobile phone possessed by a contractor. And security systems.

  In order to live in a society where accidents and crimes occur frequently, ensuring safety is important, and safety can be a business object. For example, there is a security business in which a plurality of sensors are provided in a building such as a house or office, and a security officer is dispatched as soon as an abnormality is detected to take countermeasures.

  There is a case where it is desired to confirm that the target is not a fixed object such as a building as described above but a person or an object such as a person who is moving, and that the object can be safely and freely activated. For example, at home, we want to confirm the safety of family members, for example, children. Moreover, it is preferable that a teacher who leads many students on excursions and trips can always confirm that all students are safe. For this purpose, for example, parents or guardians confirm the approximate location of each person to be protected by having a portable communication terminal such as a PHS (Personal Handy-phone System) held by a child or student (referred to as a person to be protected). Is generally done.

  A system that uses a portable terminal such as a cellular phone to notify the occurrence of an emergency or the like is known. In order to notify the occurrence of an emergency while holding a mobile phone or PHS, when an emergency button is pressed on the mobile phone etc. in the event of an emergency, or when there is no response to a regular call from the support center, etc. Disclosed is a personal name safety confirmation and rescue system using a mobile phone / PHS that determines that a situation has occurred and notifies a predetermined party to take action to avoid an emergency (for example, Patent Literature) 1).

  Also, including mobile stations and management stations, when a mobile station reports the occurrence of an emergency, the emergency situation is such that all the radio display is erased and no notification sound is output so that the criminal does not know A report radio system is disclosed (for example, refer to Patent Document 2). Furthermore, a monitoring system is disclosed in which when an emergency state is reported by a button operation of a terminal, an external connection is made to a previously registered communication device (fixed or mobile phone, etc.) to notify that an abnormality has occurred. (For example, refer to Patent Document 3).

  According to the security method and system using the portable terminal of the present invention, the following significant effects can be obtained. That is, in the event of an abnormal situation such as abduction or loss of consciousness that occurs in the contractor, the security company can immediately detect this situation and take prompt action or countermeasures. Moreover, since the message of the communication between the security company and the contractor is forged, there is no fear that it will be easily detected by a third party including the criminal. Furthermore, since the status of each contractor is clearly displayed on the display of the center device, a quick and reliable treatment is possible.

  Hereinafter, the configuration and operation of a preferred embodiment of a security method and a security system using a mobile terminal according to the present invention will be described in detail with reference to the accompanying drawings.

  First, FIG. 1 shows a system configuration diagram of a preferred embodiment of a security system according to the present invention. The security system includes a center device 10 provided by the security company and a mobile phone, a PHS, a personal digital assistant (PDA), and a portable PC (personal computer) held by a plurality of contractors individually contracted with the security company. Mobile terminals (hereinafter referred to as contract telephones) 20a to 20n.

  Here, each contract telephone 20 is a mobile terminal such as a normal mobile phone having an antenna 21 and a display unit 22 and having a function of performing wireless communication via a radio base station (not shown). Each contract telephone 20 may be a commercially available mobile phone or the like as long as it has such a wireless communication function, and does not necessarily have the same configuration. On the other hand, the center apparatus 10 registers the addresses of the contract telephones 20a to 20n (hereinafter, the reference numeral 20 may be used generically), the period set for each contract telephone 20 and the mail with appropriate contents. , Monitoring of the time from the transmission of the mail to each contract telephone 20 to the reply, and the function of detecting the occurrence of an abnormal situation when there is no reply within the time set for each contract telephone 20.

  FIG. 2 is a block diagram showing an internal configuration of a specific example of the center apparatus 10 shown in FIG. The center device 10 in this specific example includes a wireless transmission / reception unit 11, a key (KEY) 12, a ROM (Read Only Memory) 13, a RAM (Random Access Memory) 14, a CPU (Central Processing Unit) 15, and a touch display (for example, a color display). A display device 16 such as a liquid crystal display panel).

  Next, main functions of the units 11 to 16 constituting the center apparatus 10 will be described. The wireless transmission / reception unit 11 performs wireless transmission / reception with the contract telephone 20 (directly or indirectly). The key 12 performs data input and other operations to be transmitted to each contract telephone 20 or the like. The ROM 13 stores programs and data for controlling the operation of the CPU 15. The RAM 14 temporarily stores various data such as a forged message transmitted to each contractor as will be described later and its transmission cycle (or time). The CPU 15 executes the above-described various functions of the center apparatus 10 in cooperation with the wireless transmission / reception unit 11, the key 12, the ROM 13, and the RAM 14. Further, as will be described later, the touch display 16 displays the state of each contract telephone 20 under the control of the CPU 15 and in response to a touch operation by a finger of an operator (operator) of the security company.

Next, FIG. 3 shows a specific example of forged mail between each contract telephone 20 and the center device 10. 3A is a specific example of an e-mail sent from a security company (that is, the center device 10 to a specific contract telephone (for example, the contract telephone 20a).
"I bought a Southern All Stars DVD !!
Let's see together next time! !
By Hiroshi "
And 恰 is also a form of normal mail from friends, and it is unlikely that a third party will receive this mail from a security company.

On the other hand, FIG. 3B is a specific example of a response from a specific contract telephone (for example, 20a) to the center apparatus 10. A specific example of this response message is:
“I hate Southern.”
Thus, the third party sees only a normal response as a response to the mail in FIG. That is, the communication between the center device 10 of the security company and the contractor (the user of the contract telephone 20) is the content selected and determined in advance by each contractor, and is different for each contractor.

  As described above with reference to FIG. 3, the mail between the security company and each contractor is different from each other, and the mail is disguised as if it were a normal mail. Therefore, it is virtually impossible for a third party to recognize that this particular mail is a contact mail between the security company and the contractor among many mails. If necessary, each contractor may change the contents of this mail at an appropriate timing, or may prepare a plurality of mails and use them appropriately.

  Next, a preferred embodiment of the security method using the mobile terminal according to the present invention will be described with reference to the flowcharts of FIGS.

  First, initial conditions are set (step A1). In this initial condition setting, selection of a transmission message file, setting of an interval of messages transmitted from the security company center device (or security center) 10 to each contract telephone 20, setting of a transmission time zone, setting of out-of-service monitoring time, battery exhaustion Set the monitoring interruption time after the notice message, set the number of monitoring without reply to the reminder mail when there is no reply.

  After the above-described initial setting, transmission messages are randomly acquired from the transmission message file so as not to overlap (step A2). A transmission message is recorded for each terminal to be transmitted, that is, the contract telephone 20 (step A3). Then, a predetermined message is transmitted to the terminal (contract telephone) 20 (step A4).

  Next, it is determined whether or not the corresponding contract telephone 20 has received the message transmitted from the center device 10 (step A5). If there is a reply from the contract telephone 20 within a predetermined time (step A5: YES), it is determined that the contractor of the contract telephone 20 that has received this response is normal (that is, no abnormal condition has occurred) ( Step A6). Then, it is determined whether or not the next transmission timing to the contract telephone 20 has come (step A7). If it is not the next transmission timing (step A7: NO), the process returns to step A7 to wait for the next transmission timing. On the other hand, when the next transmission timing has arrived (step A7: YES), the process returns to step A2 described above, and the above-described operation is repeated.

  On the other hand, if there is no response from the terminal (contract telephone 20) in step A5 described above (step A5: NO), it is determined whether or not a time limit, that is, a preset time has elapsed (step A8). If the time limit has not been exceeded (step A8: NO), the process returns to step A5 described above and waits for a reply. On the other hand, when the time limit is exceeded (step A8: YES), it is determined that an abnormality has occurred in the contractor (that is, the user of the contract telephone 20) (step A9).

  The operation after it is determined that the above-described abnormality has occurred will be described with reference to the flowchart shown in FIG. Finally, a reply message that prompts a reply to the message transmitted by the center apparatus 10 is created (step A10). The created reminder message is transmitted to the terminal, that is, the contract telephone 20 (step A11). And it is judged whether a reply is received from a terminal (step A12).

  If received from the terminal (step A12: YES), it is determined that the contractor is normal (step A19). And it returns to step A7 mentioned above, and it is judged whether it is the next transmission timing. On the other hand, if a reply to the reminder message has not been received from the terminal (step A12: NO), it is determined whether a preset time limit has elapsed (step A13).

  If the time limit has not been exceeded (step A13: NO) in step A13, the process returns to step A12 and waits for a reply from the terminal. On the other hand, when the time limit is exceeded (step A13: YES), “no reply” is counted (counted) (step A14). It is determined whether or not the “no reply” count value has exceeded a preset number of times of monitoring (step A15). When the number of monitoring times has been exceeded (step A15: YES), it is determined that an abnormality has occurred in this terminal, that is, the user of the contract telephone 20, and the fact is displayed on the display 16 of the monitoring system and human processing (for example, , The dispatch of security guards) (step A16).

  On the other hand, if the number of monitoring times is not exceeded in the above determination (step A15: NO), it is determined whether or not there is reception from the terminal (step A17). If received from the terminal (step A17: YES), the process returns to step A19 described above and is determined to be normal. On the other hand, if there is no reception from the terminal (step A17: NO), it is determined whether or not it is the next transmission timing (step A18). If it is not the next transmission timing (step A18: NO), the process returns to step A17 described above and waits for reception from the terminal. If the next transmission timing has arrived (step A18: YES), the process returns to step A10 described above.

  Finally, a specific example of display on the touch display 16 provided in the center device 10 will be described with reference to FIG. In the specific example of FIG. 6, 25 squares indicated by numerals 1 to 25 are shown on the left side, and five rectangles indicated by numerals 1 to 5 are shown on the right end.

  In this specific example, each of the rectangles 1 to 5 represents five functions that the center device 10 has. The operator touches one of these “function 1” to “function 5” with a finger or the like to select a desired function. These functions 1 to 5 are, for example, “function 1” to “function 4” corresponding to the four functions of the center apparatus 10 described above, and “function 5” is the function of each terminal (ie, the contract telephones 20a to 20n). Displays the status (abnormal or normal). In other words, for example, “Function 1” is an address registration function of the contract telephone 20, “Function 2” is a mail transmission period setting function set for each contract telephone 20, and “Function 3” is from mail transmission to reception of a reply. The time setting function and “function 5” are functions for setting the number of times of detection without reply until the abnormality determination of each contract telephone.

  In “Function 5”, the status display of the contract telephone 20 displayed on the left side of the display scene is performed as shown in FIG. For example, for a non-abnormal (or normal) contract telephone, a green lighting display, a contract telephone for which there is an abnormality prompting a reply (for example, the 13th contract telephone) is blinking yellow and there is an abnormal A non-replying contract telephone (for example, a 19th contract telephone) is displayed in red blinking. By assigning a different color for each status in this way, the operator can determine at a glance the status of each contract telephone.

  Although not shown, when the operator touches the red flashing number or the yellow flashing number, the detailed information of the contract telephone is displayed. That is, the customer name, customer number, past history, emergency contact information, etc. of the contract telephone with an abnormality are displayed.

  Anomaly, detailed configuration and operation of a preferred embodiment of a security method and system using a mobile terminal according to the present invention, but such embodiment is merely an example of the present invention, and does not limit the present invention. Not what you want. Those skilled in the art will readily understand that various modifications and changes can be made in accordance with a specific application without departing from the gist and spirit of the present invention.

  The status display of the contract telephone shown in FIG. 6 may be a name or a telephone number instead of a simple contractor number. In particular, when there are many contract telephones, the contractor number, name, or telephone number may be listed in one or more columns, and may be scrolled at a constant speed or periodically switched and displayed on a screen basis.
