The block diagram of the communication apparatus in the 2nd Embodiment of this invention The flowchart for operation | movement description of the communication apparatus in the 2nd Embodiment of this invention

  Hereinafter, a communication apparatus according to an embodiment of the present invention and a communication system using the communication apparatus will be described with reference to the drawings. The communication apparatus of this embodiment has various functions including a camera function. These functions can be realized by a program stored in the memory of the communication device.

(First embodiment)
First, a communication system to which the communication apparatus of the present embodiment is applied will be described with reference to the drawings. The communication system according to the present embodiment includes a communication device 1 and a center device 20. In the present embodiment, as shown in FIG. 1, the use of the camera function of the communication device 1 (such as a mobile terminal or a smartphone) lent for work of a security guard P (communication device user) working at a security company. A communication system that can be used during working hours will be described as an example. The communication device 1 possessed by the security guard P is connected to a communication line NW such as the Internet network, and the center device 20 (external device) installed in the monitoring center C or another security guard P possesses it. It is possible to communicate with other communication devices.

  When the security guard P works at the office of the security company to which he belongs, the security officer P first registers the attendance at the center device in the monitoring center C using the communication device 1 or a business terminal (such as a personal computer). The security guard P waits until receiving an emergency response instruction at a predetermined location or performs a predetermined task. During the standby, if a monitoring sensor C or a monitoring camera (not shown) installed in the facility or building to be guarded reports to the monitoring center C that an abnormality has occurred, the monitoring center C possesses the guard P To the communication device 1 is sent. The security guard P uses the communication device 1 to communicate and cooperate with the monitoring center C, and copes with abnormalities (such as intrusion of suspicious persons, fires, etc.) that have occurred in facilities and buildings. In addition, we regularly patrol the property that was entrusted with security and check for any abnormalities, and perform maintenance and inspection of equipment. When the security guard P finishes the business and returns to the office, he uses the communication device 1 or the business terminal to register again for work in the center device in the monitoring center C and leaves the office.

  During the above working hours, the guard P may need to use the camera function of the communication device 1 as necessary. For example, by recording images of property conditions such as glass breaks, suspicious persons escaping, parked suspicious vehicles, etc. in a facility that is patroling, it becomes possible to respond finely thereafter. Thus, the present invention enables the security guard P to release the restriction on the camera function of the communication device 1 during working hours.

  FIG. 2 is a block diagram of the communication device 1 and the center device 20 according to the present embodiment. As illustrated in FIG. 2, the communication device 1 includes a control unit 2 that performs overall control of each unit, a touch panel 3, a communication unit 4, an imaging unit 5, and an image storage unit 6. The control unit 2 includes a mode setting unit 7. The touch panel 3 includes a display unit 8 and an operation unit 9. The communication device 1 can be realized by a mobile phone, a smartphone, a tablet PC, or a mobile terminal having the above function. The center device 20 can be realized by a server computer installed in a facility such as the monitoring center C.

  The display unit 8 has a function of displaying various information such as instruction information transmitted from the monitoring center C, for example. In addition, the operation unit 9 has a function for the guard P carrying the communication device 1 to input. The operation unit 9 can be used for the security guard P to input his / her attendance.

  The communication unit 4 has a function of communicating with the center device 20, and can send the attendance / leaving information input by the operation unit 9 to the center device 20. Also, a mode setting signal for setting the operation mode of the communication device 1 is received from the center device 20.

  The imaging unit 5 has a function of taking an image (camera function). Image data obtained by image shooting is stored in the image storage unit 6. It is preferable that the image storage unit 6 is a memory built in the main body of the communication device 1 and prohibits storage of image data in a portable medium such as an SD card.

  The mode setting unit 7 has a function of setting two operation modes (restriction mode and release mode). The restriction mode is a mode in which image capturing by the imaging unit 5 is restricted, and is set when the guard P is out of working hours. On the other hand, the release mode is a mode in which restrictions on image shooting are released, and is set when the guard P is on duty.

  In the restriction mode, acquisition of image data by the imaging unit 5 of the communication device 1 is prohibited as described above. The prohibition of image data acquisition here can be realized by a method such as prohibition of activation of an application for image acquisition, prohibition of opening a camera shutter (if any), prohibition of writing processing to the image storage unit 6, or the like. In the restriction mode, access to image data stored in the image storage unit 6 is also prohibited. As a result, all operations such as display of image data stored in the image storage unit 6 on the display unit 8, deletion of image data, copying, modification, and transmission to the outside by mail attachment are prohibited.

  In the release mode, the restriction on the camera function is released, the image acquisition unit 5 can acquire an image, and the acquired image data can be written to the image storage unit 6. Further, the image storage unit 6 can be accessed to read out the stored image data. In this release mode, image data can be read, but some restrictions may be provided, such as prohibiting deletion of image data. In this manner, the mode other than the working hours of the security guard is set to the restricted mode, the image acquisition from the imaging unit 5 and the access to the image storage unit 6 are prohibited, and the release mode is set during the working time to acquire the image from the camera. In addition, access to the image storage unit 6 is released.

  The center device 20 includes a control unit 21, a communication unit 22, and a schedule storage unit 23. The control unit 21 includes a determination unit 24 and a time measuring unit 25. In the schedule storage unit 23, the name of each guard, employee number, and the like, and the identification number of the communication device 1 lent for business use are stored in association with each other. When the attendance registration or the attendance registration is input from the communication device 1 or the business terminal and received by the center device 20, the attendance / working time information is stored as schedule information in the information of each guard. The schedule information may include not only work time information but also work place (or work area) information. By using the information on the work place (or work area), it is possible to restrict / cancel image capturing according to the place (or area) where the guard P is present. In addition, when the communication device 1 loaned to each security guard is unspecified, the communication device 1 loaned at the time of attendance registration of the security guard P may be registered from the business terminal.

  The communication unit 22 has a function of communicating with the communication device 1, and transmits a release / restriction mode signal to the communication device 1. Moreover, the attendance and attendance registration information of the guard P transmitted from the communication device 1 can be received. The communication unit 22 also has a function of communicating with the security guard P's business terminal (not shown), and the security guard P receives information such as attendance / attendance registration information transmitted from the business terminal. You can also The schedule storage unit 23 stores the work time information of the guard P received by the communication unit 22 as the schedule information of the guard P. The business terminal described here is an information terminal that can be connected to the center device 20 by wire or wireless, and indicates a personal computer, a dedicated communication device, or the like.

  The timer unit 25 has a function of measuring the current time. The determination unit 24 compares the current time obtained from the time measuring unit 25 with the schedule information stored in the schedule storage unit 23 to determine the operation mode to be set in the communication device 1. For example, when the security guard P of the communication device 1 is currently within working hours, it is determined that the “release mode” should be set. On the other hand, when the security guard P of the communication device 1 is currently out of working hours, it is determined that the “restricted mode” should be set. The operation mode determined by the determination unit 24 is stored in the schedule storage unit 23 in association with the schedule information of the guard P. At this time, when the operation mode stored in the schedule storage unit 23 is changed, that is, when the “release mode” is stored in the schedule storage unit 23 corresponding to the guard P, the determination unit 24 sets “restriction”. When it is determined that the mode should be set and the schedule storage unit 23 is changed (or when the “restricted mode” is stored and updated to the “release mode”), the communication unit 22 determines that the determination unit 24 A mode setting signal corresponding to the determination result is transmitted to the communication device 1.

  For example, when the determination unit 24 determines that the operation mode should be changed to the “restricted mode”, a mode setting signal indicating that the operation mode should be set to the “restricted mode” is transmitted to the communication device 1. Further, when the determination unit 24 determines that the operation mode should be changed to the “release mode”, the mode setting signal indicating that the operation mode should be set to the “release mode” is transmitted to the communication device 1. The communication unit 4 of the communication device 1 has a function of receiving a mode setting signal transmitted from the center device 20. Then, the mode setting unit 7 of the communication device 1 sets the operation mode of the communication device 1 according to the mode setting signal.

  The operation of the communication system according to the first embodiment configured as described above will be described with reference to the sequence diagram of FIG.

  The communication device 1 according to the present embodiment is set to a restriction mode as an initial setting (default setting), and image shooting by the imaging unit 5 is restricted. Further, when attendance registration or leaving registration is input from the communication device 1 or the business terminal, the center device 20 stores attendance / working time information in the information of each guard. As shown in FIG. 3, when the center device 20 measures the current time (S1), the center device 20 compares the current time with the working hours to determine the operation mode of the communication device 1 (S2), and the current schedule storage unit 23 If it is determined to change the operation mode stored in (2), a mode setting signal corresponding to the operation mode is transmitted to the communication device 1 (S3).

  When receiving the mode setting signal from the center device 20, the communication device 1 sets the operation mode according to the mode setting signal (S4). For example, when the communication device 1 is set to the “restricted mode” and receives a mode setting signal indicating that it should be set to the “release mode”, the operation mode is changed from the “restricted mode” to the “release mode”. To do. Then, in the communication device 1, the restriction on image shooting is released.

  According to the communication system of the first embodiment as described above, unauthorized use other than the work of the camera function of the communication device 1 can be prohibited, and information leakage from the communication device 1 can be prevented.

  That is, in the present embodiment, when the security guard P who uses the communication device 1 is out of working hours, the communication device 1 is set to the restriction mode, and image shooting by the communication device 1 is prohibited. On the other hand, when the security guard P who uses the communication device 1 is working, the communication device 1 is set to the release mode, and the restriction on image shooting is released. Thereby, use of the camera function of the communication device 1 of the security guard P can be restricted to proper use during working hours, unauthorized use other than working hours can be prohibited, and information leakage and the like can be prevented.

  In the present embodiment, in the restriction mode, writing / reading processing of image data acquired by image shooting is prohibited. In this manner, the camera function of the communication device 1 can be appropriately used during work hours, and use other than work hours (non-regular use) can be easily prohibited.

  In the present embodiment, the acquisition of images from the imaging unit 5 is restricted in the restriction mode, but there are cases where photographing by the camera function is required even outside working hours. For example, when a traffic accident is encountered outside working hours and an evidence photograph is to be acquired, it is preferable to enable image acquisition.

  Therefore, in the restriction mode, it is possible to acquire an image from the imaging unit 5 and store the image in the image storage unit 6, and prohibit reading processing of image data from the image storage unit 6. In this case, the image storage unit 6 may be configured to have different storage areas for the first storage unit that stores the image data in the restriction mode and the second storage unit that stores the image data in the release mode.

  Also, in this case, it is preferable that the acquired image data is not permitted to be viewed by the security guard P in the restricted mode, and can be accessed by a specific administrator under a predetermined condition (for example, password input). It is. That is, the authority is set to the first storage unit so that the image data acquired by image photographing cannot be written / read out even during working hours. On the other hand, in the release mode, writing / reading processing of image data acquired by image shooting is performed on a storage unit (second storage unit) that is allowed to be accessed only during working hours. The guard P cannot read out the image data acquired by image shooting for any storage unit outside the working hours.

  In this way, the use of the camera function of the communication device 1 other than business (non-regular use) can be easily prohibited. Moreover, it becomes easy to set a restriction by dividing the storage area.

  Further, in the present embodiment, the center device 20 has registered the attendance time when the security guard P attends work from the communication device 1 or the business terminal, the attendance time when the attendance is registered, and the retirement registration when the work ends. The actual working hours from the attendance registration time to the attendance registration time are managed as schedule information of the security guard P. Instead of this, the scheduled work time of the guard P may be input in advance and used as schedule information.

  Thereby, the operation mode of the communication apparatus 1 can be appropriately set even when attending work earlier than necessary and registering work or when returning to work after leaving work registration.

  Furthermore, it is also possible to use the scheduled work time input in advance and the attendance / registration information as schedule information. For example, if the attendance registration is recorded earlier than the pre-registered attendance time, the restriction of the communication device 1 is canceled after waiting for the pre-registered attendance time, and the attendance registration is performed earlier than the pre-registered attendance time. In the case where the job is registered, a signal is transmitted to the communication device 1 so as to shift from the cancellation mode to the restriction mode with the retirement registration. In other words, in this case, the schedule information is from the previously entered work time to the time when the work is registered, and the restriction of the communication device 1 is canceled during that time. On the other hand, if the attendance registration is not entered before the pre-registered attendance time, the restriction of the communication device 1 is canceled due to the arrival of the attendance time. If the attendance registration is not entered before the pre-registered attendance time, the employee is retired A signal is transmitted to the communication apparatus 1 so as to shift from the release mode to the restriction mode when time arrives.

  As a result, the camera function of the communication device 1 can be appropriately set in accordance with the work situation of the guard P. In this way, each communication device 1 can appropriately set the operation mode of the communication device 1 based on the actual working situation of each guard P managed collectively by the center device 20.

(Second Embodiment)
Next, a communication apparatus according to the second embodiment of this invention will be described. Here, the communication device 10 of the second embodiment will be described focusing on differences from the communication system of the first embodiment. Unless otherwise specified, the configuration and operation of the present embodiment are the same as those of the first embodiment.

  The configuration of the communication apparatus 10 according to the present embodiment will be described with reference to the drawings. FIG. 4 is a block diagram of the communication apparatus 10 according to the present embodiment. As shown in FIG. 4, the communication device 10 further includes a timer unit 12, a determination unit 13, and a schedule storage unit 14 in addition to the configuration of the first embodiment.

  In the schedule storage unit 14, information on the working hours of the guard P of the communication device 10 is stored in advance as schedule information of the guard P. Similar to the first embodiment, the schedule information may include not only work time information but also work place (or work area) information. By using the information on the work place (or work area), it is possible to restrict / cancel image capturing according to the place (or area) where the guard P is present. The schedule storage unit 14 stores the current operation mode determined by the determination unit 13 in association with the schedule information of the guard P.

  The communication unit 4 has a function of communicating with a center device (not shown in FIG. 4), and can receive the security guard P schedule information from the center device. Therefore, for example, among the information on the scheduled work time of each guard P managed collectively by the center device, the scheduled work time of the guard P carrying the communication device 1 can be received as schedule information. As for the scheduled work time of each guard, information input from the business terminal or the like by the manager or the guard P can be received via the center device. The schedule storage unit 14 stores the information on the working hours of the guard P received by the communication unit 4 as the schedule information of the guard P.

  Further, whether or not the guard P is working may be input by the guard P from the operation unit 9. When attendance registration is performed from the operation unit 9, the schedule storage unit 14 can also store the time when the attendance registration input from the operation unit 9 is made as schedule information as the work start time of the guard P. Similarly, when the work is completed and the employee is registered for retirement from the operation unit 9, it can be stored as the work end time. For the attendance registration and the attendance registration, an application capable of registering the attendance and attendance dedicated to the communication device 1 is installed. When the attendance / attendance registration is performed, the mode setting unit 7 may be able to change the operation mode only when the communication unit 4 transmits an attendance / exit signal to the center device 20 and receives an approval signal from the center device 20.

  The operation of the communication apparatus 1 according to the second embodiment configured as described above will be described with reference to the flowchart of FIG.

  As shown in FIG. 5, the communication device 10 according to the present embodiment is set to a restriction mode as an initial setting (default setting), and image photographing by the imaging unit 5 is restricted (S10). When measuring the current time (S11), the communication device 1 compares the current time with the working time and determines the operation mode of the communication device 1 (S12). If the current time is within the working hours of the security guard P (S13), the operation mode is changed from “restricted mode” to “cancellation mode”, and the restriction on image photographing by the photographing unit 5 is removed. (S14). If it is not within working hours, the process returns to S11 again, and the current time and working hours are compared. When the operation mode is changed to the “release mode”, the current time is again measured (S15), and the operation time of the communication apparatus 1 is determined by comparing the current time with the working time (S16). If the current time is outside the guard's working hours (S17), the operation mode is changed from "release mode" to "restricted mode", and image shooting by the shooting unit 5 is restricted again (S18). ).

  The communication device 10 according to the second embodiment also has the same effects as the communication system according to the first embodiment. In other words, the camera function of the communication device 10 can be used appropriately when necessary during working hours, and unauthorized use can be prohibited by restricting the use during non-working hours. Information leakage from the device 10 can be prevented.

  Also in the present embodiment, in the restricted mode, writing / reading processing of image data acquired by image shooting is prohibited. In this way, the use of the camera function of the communication device 10 other than business (non-regular use) can be easily prohibited.

  Also in this case, similarly to the first embodiment, the storage unit that performs the writing / reading process of the image data acquired by the image capturing may be different between the restriction mode and the release mode. In the restriction mode, writing of image data acquired by image shooting is permitted to a storage unit (first storage unit) that prohibits read access in principle. Regardless of the working hours inside or outside, the guard P who is lent the communication device 1 cannot read out the image data acquired by the image photographing to the storage unit. The first storage unit can be accessed by satisfying a predetermined condition (password input or the like) by the administrator.
