Description

  The present invention relates to a mobile terminal and a method and program for controlling the mobile terminal.

  Conventionally, in facilities such as offices, stores, and homes, security systems that install various sensors and monitoring cameras to monitor the safety status of buildings have been used. In the security service using such a security system, these mobile terminals have come to be used with the spread of mobile terminals such as smartphones and tablet terminals in recent years. For example, a security guard receives information necessary for security such as a map of a facility to be guarded, a sketch, a security schedule, inspection items, etc. from a center device using a mobile terminal, and displays the security information on the screen of the mobile terminal. Security can be done while. Moreover, the guard can take a monitoring image or input an inspection record at any time using the portable terminal while guarding, and can send the information to the center device.

  Patent Document 1 describes a portable terminal that can transmit an emergency call signal to a monitoring center device with a simple operation. The user of this mobile terminal can make emergency input by a simple operation such as long-pressing a specific button, so in the event of a disaster or encountering a suspicious person, an emergency call is quickly made to a remote monitoring center device. It can be carried out.

  On the other hand, highly confidential information including customer personal information such as security information and monitoring images and confidential matters on business is stored in a portable terminal used for security and other business. Therefore, in Patent Documents 2 and 3, in order to ensure the confidentiality of information stored in the mobile terminal, the input operation is automatically locked when the mobile terminal is not operated for a certain period of time after unlocking. The automatic lock function is described. Once the lock is set, these mobile terminals cannot perform an input operation unless an unlock operation is performed by inputting a personal identification number or the like.

  This automatic lock function is useful in that it prevents leakage of confidential information stored in the mobile terminal when the mobile terminal is lost or robbed. In particular, during the patrol, the guard frequently operates the mobile terminal such as inputting inspection records to the mobile terminal while displaying the inspection items on the screen. In this case, if no operation is performed on the mobile terminal for a certain period of time, there is a high possibility that some abnormal situation such as loss or theft of the mobile terminal has occurred. Therefore, by locking the input operation by the automatic lock function of the mobile terminal, it is possible to prevent a malicious third party from freely operating the mobile terminal to extract information.

  On the other hand, for example, standing guards monitor and intimidate passers-by at the entrances and exits of facilities and do not use mobile terminals except during emergency calls. Therefore, if the mobile terminal is locked by the automatic lock function while standing, when an emergency occurs, an unlocking operation is required, and emergency input cannot be performed immediately. Therefore, even if an emergency input can be performed with a simple operation as in the portable terminal of Patent Document 1, there is a problem that it is difficult to release the lock and an emergency report cannot be sent to the center device quickly. However, if the time until the lock is inadvertently increased, the time that the portable terminal is left unlocked when the mobile terminal is stolen or lost increases, so the risk of information leakage increases.

While standing, the guard B can make an emergency call to the center device 3 via the communication network 5 by the mobile terminal 2 when an emergency such as the discovery of a suspicious person occurs. However, the standing guard B normally does not use the portable terminal 2 except in an emergency.

  Furthermore, for example, the security guard C receives an abnormality handling instruction from the center device 3 by the mobile terminal 2, and rushes to a place where the abnormality is detected to perform an abnormality handling operation such as an inspection. When the center device 3 is notified of the abnormality of various sensors (not shown) connected to the security device 4 from the security device 4 via the communication network 5, the command for handling the abnormality is sent from the communication network 5. The data is sent to the mobile terminal 2 via the base station or the access point 51. As a result of the inspection of the abnormality, the security guard C may report the inspection result to the center device 3 through the communication network 5 using the portable terminal 2, or may make an emergency request such as relief if necessary. it can.

  Thus, the frequency with which the guard operates the mobile terminal 2 varies depending on the type of work performed by the guard, such as patrol, standing up, and handling anomalies. Therefore, the mobile terminal 2 according to the present invention appropriately sets the lock time until the lock of the mobile terminal 2 becomes effective according to the type of work performed by the guard.

  FIG. 2 is a configuration diagram illustrating an example of a security system 1 in which the mobile terminal 2 according to an embodiment of the present invention is used. As shown in FIG. 2, such a security system 1 includes a mobile terminal 2 used for security work, a center device 3 that monitors and manages the security system 1, a suspicious person invading or generating a fire in a security target facility, and the like.

  As illustrated in FIG. 2, the storage unit 27 stores an input operation mode, a usage state, a lock time, lock time correspondence information, and schedule information.

  The input operation mode is information indicating whether or not input restriction to the operation unit 21 is set. For example, when the input operation mode is the input restriction mode, it indicates that the input restriction to the operation unit 21 is set. When the input operation mode is the input permission mode, the input restriction to the operation unit 21 is released. Indicates that

  The usage state is information indicating the current usage state by the user of the mobile terminal 2, and an appropriate lock time differs depending on this. For example, the usage state may be the type of work performed by the user of the mobile terminal 2. In the present embodiment, the use status indicates any one of the security operations among patrol, standing up, abnormality handling, and others.

  The lock time is information indicating the time until the input restriction to the operation unit 21 is set. In other words, when the input restriction to the operation unit 21 is released and the time during which the input operation of the operation unit 21 is not performed reaches the lock time, the input restriction to the operation unit 21 (input restriction mode) is set. . When the usage state of the mobile terminal 2 changes, the lock time corresponding to the changed usage state is set.

  The lock time correspondence information is information indicating an appropriate lock time corresponding to each use state. For example, the lock time correspondence information may be information in which an appropriate lock time is associated in a table format with respect to various types of security operations such as patrol, standing, abnormality handling, and others.

  For example, it is possible to associate a relatively short time such as 10 minutes as an appropriate lock time with an operation such as patrol that frequently operates the mobile terminal 2. On the other hand, it is preferable to associate a relatively long time such as one hour, which is an implementation unit for performing a standing job, with a task that does not use the portable terminal 2 other than an emergency call during guarding, such as standing. In the case of handling an abnormality, the mobile terminal 2 is not operated as frequently as the patrol, but when an abnormality occurs when the security device 4 detects an abnormality, the portable terminal 2 can be robbed or dropped by a suspicious person who is the cause of the abnormality. Since the property is high, a time that is a little longer than the patrol such as 15 minutes and shorter than the standing time may be associated.

  The schedule information is information indicating a work schedule of the user of the mobile terminal 2. For example, when the security guard inputs an employee number or the like by the operation unit 21 of the portable terminal 2 at the start of work and performs an operation for starting the work, a signal indicating the start of work together with information such as the employee number is transmitted. The data is sent to the center device 3 through the communication network 5 by the processing unit 26. The center device 3 receives the schedule information corresponding to the received employee number and date together with the security information necessary for other guards such as a map of the facility to be guarded and a floor plan and inspection items via the communication network 5. Can be sent to. The schedule information sent from the center device 3 is received by the communication processing unit 26 of the mobile terminal 2 and stored in the storage unit 27.

  FIG. 3 is a diagram illustrating an example of schedule information stored in the mobile terminal 2 according to an embodiment of the present invention. As shown in FIG. 3, for example, schedule information is prepared for each guard for each day, and one or more time zones indicated by employee number and date, start time and end time, A type of security service such as patrol or standing, and a place where the security service is performed, associated with each time zone.

  FIG. 4 is a configuration diagram of the control unit 28 in the mobile terminal 2 according to the embodiment of the present invention. As shown in FIG. 4, the control unit 28 includes a use state determination unit 281, a lock time setting unit 282, an input restriction setting unit 283, an input restriction release unit 284, and an emergency notification unit 285. Each unit of the control unit 28 is realized by the processor reading and executing a program describing the processing procedure of each unit stored in the storage unit 27.

  The use state determination unit 281 is periodically executed during the release of the input restriction in the process of managing the lock time performed by the control unit 28. The lock time management process will be described in detail later with reference to the flowchart of FIG.

  The usage state determination unit 281 determines whether or not the usage state by the user of the mobile terminal 2 has changed. If the usage state has changed, the usage state stored in the storage unit 27 is changed to the changed usage state. change. For example, the use state determination unit 281 newly determines the use state of the mobile terminal 2 at that time, and compares the new use state with the use state stored in the storage unit 27. If the compared use states are the same, the use state determination unit 281 determines that the use state has not changed. On the other hand, when the compared use states are different from each other, the use state determination unit 281 determines that the use state has changed, and replaces the use state stored in the storage unit 27 with a new use state.

  As described below, the usage state determination unit 281 can determine a new usage state of the mobile terminal 2 by various methods.

  For example, the usage state determination unit 281 can determine a new usage state based on information input from the operation unit 21 by the user.

  FIG. 5 is a diagram illustrating an example of a job selection screen for selecting a security job in the mobile terminal 2 according to an embodiment of the present invention. As shown in FIG. 5, on this task selection screen, menu buttons indicating “start standing”, “start patrol”, “abnormality handling”, and “other” security tasks are displayed. This job selection screen may be, for example, a screen for starting a support program corresponding to each security job. For example, the control unit 28 may display a job selection screen on the display unit 22 when the user inputs the start of a security job from the operation unit 21. The use state determination unit 281 can receive the security work selected by the user through the operation unit 21 on the work selection screen from the control unit 28 and determine it as a new use state.

  Further, the use state determination unit 281 can determine a new use state of the mobile terminal 2 based on the schedule information stored in the storage unit 27. For example, in the case of the schedule information shown in FIG. 3, the use state determination unit 281 compares one or more time zones with the current time in the schedule information corresponding to the employee number and date of the guard, The security service associated with the current time zone can be determined as a new usage state of the mobile terminal 2.

  Further, the usage state determination unit 281 includes a business area where business is performed, a bar code, a QR code (registered trademark), an RF tag, or the like pasted on a door, a pillar, a wall, a signboard, etc. A new usage state can be determined from the sign indicating the type of business. The use state determination unit 281 can determine a security service corresponding to a label such as a barcode, QR code (registered trademark), or RF tag read by the reading unit 25 as a new use state.

  The lock time setting unit 282 sets an appropriate lock time according to the use state stored in the storage unit 27 when the use state determination unit 281 determines that the use state of the mobile terminal 2 has changed. The lock time setting unit 282 replaces the lock time associated with the use state in the lock time correspondence information stored in the storage unit 27 with the lock time stored in the storage unit 27 as an appropriate lock time. Note that when the usage state is standing up, the lock time setting unit 282 obtains the execution time from the start time to the end time of standing up from the schedule information stored in the storage unit 27, and the obtained time is the lock time. May be set.

  The input restriction setting unit 283 sets the input operation mode stored in the storage unit 27 to the input restriction mode so that the input restriction to the operation unit 21 is set.

  The input restriction release unit 284 sets the input operation mode stored in the storage unit 27 to the input permission mode, and sets the input restriction to the operation unit 21 to be released.

  The emergency notification unit 285 notifies the center device 3 that an emergency has occurred in the security target facility. The emergency notification unit 285 sends an emergency notification signal indicating that an emergency has occurred at the security target facility to the center device 3 via the communication network 5 by the communication processing unit 26.

  FIG. 6 is a flowchart illustrating an example of an operation related to an input operation in the mobile terminal 2 according to an embodiment of the present invention. This operation is executed by a basic program such as an operating system in an input operation of an arbitrary process executed by the mobile terminal 2 having the lock function.

  As shown in FIG. 6, when the operation of the input operation is started, the control unit 28 determines whether or not there is an input operation to the operation unit 21 by the user based on the output from the operation unit 21. If there is no input operation (No in step S601), the process is terminated. When there is an input operation of the operation unit 21 (Yes in step S601), the control unit 28 refers to the input operation mode stored in the storage unit 27 and determines whether or not the input restriction is set. (Step S602). If the input restriction is not set (No in step S602), the control unit 28 determines whether the input operation corresponding to the signal received from the operation unit 21 is an emergency input such as a long press of a button. (Step S603). If the input operation is an emergency input (Yes in step S603), the control unit 28 performs an emergency notification process by the emergency notification unit 285 (step S604). If the input operation is not an emergency input (No in step S603), the control unit 28 performs normal input processing according to the input operation (step S605).

  On the other hand, when the input restriction is set (Yes in step S602), the control unit 28 performs an input restriction release determination process for determining whether or not to release the input restriction by the authentication of the user who performed the input operation. (Step S606).

  FIG. 7 is a diagram illustrating an example of a user authentication screen for performing user authentication in the mobile terminal 2 according to the embodiment of the present invention. As shown in FIG. 7, in order to authenticate the user, the control unit 28 can display a user authentication screen on the display unit 22. On this user authentication screen, the user can touch the numeric keys on the numeric keypad displayed on the display unit 22 and input the password. The control unit 28 receives signals corresponding to the numbers touched by the user from the operation unit 21, and collates the input code numbers corresponding to these signals with the registered code numbers registered in the portable terminal 2. If these passwords match, the control unit 28 determines that the user who has performed the input operation is an authorized user of the portable terminal 2, and restricts input to the operation unit 21 by the input restriction release unit 284. To release.

  As in the operation related to the input operation shown in FIG. 6, when the input restriction of the operation unit 21 is normally set, the user must release the input restriction by inputting a password on the user authentication screen. Thus, the emergency call input operation cannot be performed by the operation unit 21. For this reason, for example, if the lock time elapses while the guard does not operate the mobile terminal 2 while standing, and the input restriction of the operation unit 21 is set, an emergency such as the discovery of a suspicious person has occurred. Sometimes, it takes time to input a password, and there is a possibility that an emergency call cannot be made immediately. Therefore, in the mobile terminal 2 according to the present invention, the control unit 28 manages the user to set an appropriate lock time according to the usage state such as the type of business using the mobile terminal 2.

  FIG. 8 is a flowchart showing processing for managing the lock time in the mobile terminal 2 according to the embodiment of the present invention. This lock time management process is performed in parallel with other processes executed on the mobile terminal 2. The priority of the lock time management process can be set low so as not to interfere with other important processes.

  When the portable terminal 2 is turned on, the control unit 28 sets the input operation mode to the state where the input restriction is set by the input restriction setting unit 283 (input restriction mode) (step S801). And the control part 28 reads the input operation mode memorize | stored in the memory | storage part 27, and determines whether the input restriction | limiting was cancelled | released (step S802). When the input restriction has not been released (No in step S802), the control unit 28 determines whether or not the power of the mobile terminal 2 is turned off (step S803), and when the power of the mobile terminal 2 is turned off (step S803). If the process ends and the power is not turned off (No in step S803), the process returns to step S802.

  The control unit 28 repeats the processing of steps S802 to S803 until the input restriction is released. When the input restriction is released (Yes in step S802), the timer unit 23 is reset and the elapsed time by the timer unit 23 is set. Time measurement is started (step S804). And the control part 28 determines whether the use condition of the portable terminal 2 changed by the use condition determination part 281 (step S805). When the use state determination unit 281 determines that the use state has changed (Yes in step S806), the control unit 28 sets an appropriate lock time according to the use state by the lock time setting unit 282 (step S810). The process proceeds to step S807. On the other hand, when the use state determination unit 281 determines that the use state has not changed (No in step S806), the control unit 28 proceeds directly to step S807.

  In step S <b> 807, the control unit 28 determines whether or not there is an input operation to the operation unit 21 based on the output from the operation unit 21. If there is an input operation to the operation unit 21 (Yes in step S807), the control unit 28 resets the timer unit 23 (step S808), and proceeds to step S809. When there is no input operation to the operation unit 21 (No in Step S807), the control unit 28 determines whether the elapsed time from the input operation has reached the lock time based on the time counter or the output of the timer unit 23. Is determined (step S811).

  When the elapsed time has not reached the lock time (No in step S811), the control unit 28 determines that the elapsed time from the input operation is a predetermined time before the lock time (for example, 1) based on the time counter or the output of the timer unit 23. It is determined whether or not (minutes ago) has been reached (step S812). When the elapsed time reaches a predetermined time before the lock time (Yes in step S812), the control unit 28 notifies that the input limit is set soon by the notification unit 24 (step S813), and proceeds to step S809. . If the elapsed time has not reached the predetermined time before the lock time (No in step S812), the control unit 28 proceeds to step S809 without performing notification output.

  When the elapsed time reaches the lock time (Yes in step S811), the control unit 28 causes the input restriction setting unit 283 to set the input operation mode to the state where the input restriction is set (step S814). Further, the control unit 28 reads the use state stored in the storage unit 27 and determines whether or not the use state of the mobile terminal 2 is standing (step S815). If the use state of the mobile terminal 2 is not standing (No in Step S815), the control unit 28 returns to Step S802. If the use state of the mobile terminal 2 is standing (Yes in step S815), the mobile terminal 2 has been left for a long time without being input, and there is a high possibility of loss or theft. In particular, when the standing time is set as the lock time, operations such as a business report and a work end are not performed even though the end time has passed. Therefore, the control unit 28 sends an emergency notification signal to the center device 3 by the emergency notification unit 285 (step S816), and returns to step S802.

  As described above, according to the present invention, the mobile terminal can set an appropriate lock time according to the usage state of the mobile terminal. In particular, the mobile terminal according to the embodiment of the present invention can set an appropriate lock time according to the type of business having a different frequency of operating the mobile terminal. Thus, for example, if the user of the mobile terminal is performing a task of frequently operating the mobile terminal such as patrol, set a relatively short lock time, other than emergency notification such as standing up When doing business without using a mobile terminal, it is possible to set a relatively long lock time because it stays in the same place and is less likely to be lost or stolen. In addition, when the user is dealing with anomalies, it is not necessary to operate the mobile device frequently as in patrols, but because the risk of loss or robbery of the mobile device is high, it is shorter than standing, but from patrol A slightly longer lock time can be set. Thereby, it is possible to save as much as possible the troublesome operation for unlocking at the time of emergency call while keeping the time for which the lock is released when the mobile terminal is lost or stolen as short as possible. Therefore, according to the mobile terminal of the present invention, it is possible to promptly make an emergency call while ensuring the confidentiality of the information stored in the mobile terminal.

  In addition, the mobile terminal according to one aspect of the present invention does not perform an input operation when the input operation to the operation unit is locked after the lock time has passed without the mobile terminal being operated while the user is standing. However, an emergency call can be automatically sent to the center device. Therefore, according to the present invention, when there is a high possibility that the mobile terminal has been lost or stolen in this way, the input operation of the mobile terminal can be locked, and an emergency call can be quickly sent to the center device.

  Furthermore, the mobile terminal according to one embodiment of the present invention can input the usage state of the mobile terminal by the user from the operation unit. Therefore, according to the present invention, the usage state of the portable terminal can be changed by a user input, and the lock time can be changed appropriately.

  Moreover, the portable terminal which concerns on the other aspect of this invention can determine the use condition of the portable terminal by a user based on the schedule information received from the center apparatus. Therefore, according to the present invention, the usage state of the mobile terminal can be automatically changed according to the current time, and the lock time can be changed appropriately.

  Furthermore, the mobile terminal according to another embodiment of the present invention can determine the usage state of the mobile terminal by the user by reading it from a sign placed in the business area with a reading unit. Therefore, according to the present invention, it is possible to automatically change the usage state of the mobile terminal according to the location where the security guard performs security and appropriately change the lock time.

  The preferred embodiments of the present invention have been described above, but the present invention is not limited to these embodiments. For example, in the above embodiment, authentication of the user of the mobile terminal is performed by inputting a personal identification number from the operation unit, but the present invention is not limited to this. For example, the user authentication may be performed by another authentication method based on an RF tag such as a user's fingerprint, face, voiceprint, or employee ID acquired from the reading unit or the operation unit.

  In the above embodiment, the mobile terminal used for security work by the security guard is described. However, the mobile terminal according to the present invention is used for other work such as building cleaning and maintenance, inspection of various equipment, maintenance and repair. May be used.
