When acquiring the business information, the information processing unit 272 encrypts the acquired business information with a common key and stores the encrypted business information in the storage unit 26. As with the image information, when the business information is encrypted, the business information before encryption is deleted, but the mobile terminal 2 can decrypt the business information encrypted with the common key with the common key. Therefore, business information can be browsed, updated or changed thereafter. That is, the information processing unit 272 reads and decodes the business information stored in the storage unit 26 when the operation unit 23 receives an instruction to update the business information from the security guard, and edits the security unit using the operation unit 23. The business information is changed based on the input, and the changed business information is encrypted again and stored in the storage unit 26.
In addition, the information processing unit 272 transmits the encrypted business information stored in the storage unit 26 to the center device 3 via the communication processing unit 21 when the operation unit 23 receives a transmission instruction from the guard. Then, the business information that has been transmitted to the center device 3 is deleted from the storage unit 26.

  Further, the information processing unit 272 determines whether image information or audio information remains in the storage unit 26 when the operation unit 23 receives a transmission instruction from a guard. When there is untransferred image information or audio information that remains without being transmitted to the center apparatus 3 due to a poor communication state or the like, the information processing unit 272 displays the image remaining in the storage unit 26 together with the business information. Information or voice information is transmitted to the center device 3 via the communication processing unit 21. Then, the information processing unit 272 deletes from the storage unit 26 the image information or audio information that has been transmitted to the center device 3. As a result, when the security guard images the inspection location, the mobile terminal 2 remains in the mobile terminal 2 without transmitting image information or audio information to the center device 3 even if the communication state is poor. It can be prevented from being left.

  The information processing unit 272 indicates that when transmission of business information, image information, or audio information is not possible due to a bad communication state or the like, the information cannot be transmitted. A message for prompting retransmission later may be displayed on the display unit 22.

  When the operation unit 23 receives an instruction to end work from the security guard, the work end processing unit 273 sends a leave signal to the communication processing unit if untransferred business information, image information, and audio information are not stored in the storage unit 26. The data is transmitted to the center device 3 via 21. When the work end processing unit 273 receives the leave response signal from the center device 3 via the communication processing unit 21, the security end information, the common key, and the public key acquired from the center device 3 are deleted from the storage unit 26. To do. On the other hand, the work end processing unit 273 does not transmit the leave signal to the center device 3 when untransferred business information, image information, or audio information is stored in the storage unit 26. As a result, the mobile terminal 2 is left with the business information, image information, or audio information left on the mobile terminal 2 because the user forgets to transmit the business information, image information, or audio information to the center device 3. Can be prevented.

  FIG. 6 is a flowchart showing the operation of the image information acquisition process executed by the information processing unit 272 according to this embodiment.

  As described above, when the mobile terminal according to an embodiment of the present invention acquires image information or audio information, the mobile terminal immediately transmits the acquired image information or audio information to the center device, while being input by a security guard. The received business information is not transmitted immediately, but is transmitted to the center device in accordance with instructions from the security guard. The mobile terminal may be updated or changed on the spot by the security staff while immediately transmitting image information or audio information required in real time by the surveillance staff at the monitoring center who cannot directly see the situation at the scene. Since certain business information is transmitted in accordance with instructions from the security guard, the acquired information can be transmitted to the center device at an appropriate timing.

  In addition, every time transmission of business information, image information, or audio information is completed, the mobile terminal deletes the transmitted business information, image information, or audio information from the storage unit of the mobile terminal. Therefore, business information, image information, or audio information is never left in the portable terminal, and security problems such as unauthorized leakage can be prevented.

  The preferred embodiments of the present invention have been described above, but the present invention is not limited to these embodiments. For example, the information that is immediately transmitted to the center device upon acquisition is not limited to image information and audio information, and may be any information as long as the information is different from the information transmitted in accordance with instructions from the security guard. For example, the information processing unit processes information acquired from other devices, such as weather observation data and measured values of harmful substances in the atmosphere, by the communication processing unit or an unillustrated input unit in the same manner as image information or audio information. When these pieces of information are acquired, the acquired information may be immediately transmitted to the center device and deleted when transmission is completed.

  Further, the information to be transmitted immediately and the information to be transmitted in accordance with instructions from the security guard are not fixedly determined, but may be set in advance by the security staff using the operation unit. In that case, for example, an input device to which information to be transmitted immediately is input and an input device to which information to be transmitted is input in accordance with instructions from the guard are set by the guard using the operation unit and stored in the storage unit. The When the information processing unit acquires information from each input device, the information processing unit transmits the information to the center device according to the setting stored in the storage unit. Thereby, the guard can flexibly determine the information to be transmitted immediately and the information to be transmitted at the timing instructed by the guard.

Further, the information processing unit may immediately transmit the information determined to be transmitted immediately to the center apparatus only when the information is acquired at a preset time. In this case, for example, the time for performing immediate transmission is set by the guard using the operation unit and stored in the storage unit. When the information processing unit acquires information from each input device, the information processing unit determines whether or not the current time is within the set time. Only when the current time is within the set time, the information processing unit immediately transmits the acquired information to the center device, and when the current time is not within the set time, the acquired information is When the transmission is instructed by the security guard, it is transmitted to the center device. Accordingly, for example, the mobile terminal can immediately transmit only the image information captured while the guard is working, and can transmit the image information captured outside the working time at a timing instructed by the guard.
Similarly, the information processing unit may immediately transmit the information determined to be transmitted immediately to the center apparatus only when the information is acquired at a preset location. In this case, for example, the range of the place where immediate transmission is performed is set by the guard using the operation unit and stored in the storage unit. The portable terminal has a position measuring unit that measures the current position of the portable terminal using GPS (Global Positioning System) or the like, and the information processing unit is measured by the position measuring unit when acquiring information from each input device. It is determined whether the current position is within the set range. The information processing unit immediately transmits the acquired information to the center device only when the current position is within the set range. When the current position is not within the set range, the information processing unit When the transmission is instructed by a member, it is transmitted to the center device. Thereby, for example, the mobile terminal can immediately transmit only the image information captured at the inspection location, and can transmit the image information captured at a location other than the inspection location at the timing instructed by the security guard.

  In addition, the work end processing unit receives untransferred business information, image information, or audio information when untransferred business information, image information, or audio information remains when an instruction to end work is received from a security guard. You may transmit to a center apparatus via a communication processing part. In this case, the work end processing unit displays a list of untransferred business information, image information, or audio information on the display unit before sending the business information, image information, or audio information to the center device, and displays the list of security information to the security guard. You may confirm whether you may transmit to.

  For example, in the present embodiment, the security system has been described as an example. However, the information management system according to the present invention can be applied to a system used in the police, the Self-Defense Force, the local government, and the like.
