The display unit 45 includes a display device such as an LCD (Liquid Crystal Display), and is used for displaying various menu screens and video information.

  The video storage unit 46 stores video information extracted from the video recording device 13. As will be described later, in the video storage unit 46, the video information is classified and managed by location information. The memory card 47 is detachably attached to the mobile terminal 14. The video information classified and managed in the video storage unit 46 can be recorded on the memory card 47 and provided to the external computer 50. The computer 50 exists as a host computer for managing the cars 11a and 11b in an integrated manner.

  The transmission / reception device 48 is used when wirelessly transmitting / receiving information to / from the transmission / reception devices 16a, 16b provided on the side of the cars 11a, 11b. As the communication means in this case, as described above, infrared rays, wireless LAN, Bluetooth (registered trademark), or the like is used.

  The filter circuit 49 is used to extract location information from the video information when the video information including the location information is acquired from the cars 11a and 11b.

  In the security video monitoring system having such a configuration, the security cameras 12a and 12b installed in the cars 11a and 11b, which are places where security is required, perform shooting operations at predetermined time intervals. Video information obtained by the security camera 12a is sequentially sent to the video recording device 13a via the photographing cable 18a. In the video recording device 13a, this video information is converted into a plurality of continuous still images while being compressed by a predetermined method, and then written into the captured video recording area 33a of the storage unit 33. The same applies to the video information obtained by the security camera 12b, which is sequentially sent to the video recording device 13b via the photographing cable 18b and recorded.

  Here, when the video information recorded in the video recording devices 13a and 13b is taken out, when the operation state of the video recording devices 13a and 13b is confirmed, or when the operating conditions are changed, the maintenance staff is a portable terminal. 14, the video recording devices 13a and 13b can be remotely operated.

  When the video recording devices 13a and 13b are remotely operated using the mobile terminal 14, the mobile terminal 14 needs to input an ID. That is, for example, when remotely operating the video recording device 13a installed in the car 11a, a legitimate operation is performed when the ID input to the mobile terminal 14 matches the ID registered in advance in the video recording device 13a. Remote operation is permitted.

  This ID collation processing may be provided in the portable terminal 14 or may be provided in the video recording device 13a. When it is given to the portable terminal 14, the portable terminal 14 requests an ID from the video recording device 13a. In response to this request, the ID sent from the video recording device 13a via the transmission / reception device 16a and the ID input by the operator are collated in the portable terminal 14. On the other hand, when the video recording device 13a is provided, the ID input by the operator is transmitted from the portable terminal 14. The video recording device 13a receives the operator's ID via the transmission / reception device 16a and collates it with the ID registered in itself.

  As a result of this ID collation, if it is determined that the operator is a legitimate operator, in addition to the video information recorded in the video recording device 13a through the transmission / reception device 16a provided in the security camera 12a, the operating state of the video recording device 13a Various information necessary for maintenance such as operating conditions can be extracted. The various information necessary for the maintenance includes the operation state and operation conditions of the security camera 12a.

  That is, as information related to devices installed in the car 11a, not only information related to the video recording device 13a but also information related to the security camera 12a can be acquired through the transmission / reception device 16a. The same applies to the video recording device 13b and the security camera 12b installed in the car 11b.

  Thus, in the cars 11a and 11b, maintenance personnel can easily collect various information necessary for maintenance including video information using the mobile terminal 14. However, the video information captured by the security cameras 12a and 12b can be managed for each car in the state stored in the video recording devices 13a and 13b. There is a problem that it is difficult to know which car information is about which car.

  Therefore, in the present embodiment, the above-described problem is solved by adding information that can specify the shooting location to the video information. In the following, the processing operation will be described assuming the case where video information taken by the security camera 12a in the car 11a is classified and managed.

  As shown in FIG. 2, location information is stored in the shooting location storage area 23a of the storage unit 23 provided in the security camera 12a. This location information is information for specifying the shooting location of the security camera, and is made up of character information representing the name of the shooting location, for example, “Inside the car of No. A”.

  The location information can be arbitrarily set from the outside. That is, the maintenance staff accesses the security camera 12a through the portable terminal 14, and transmits arbitrary character information as location information by a predetermined operation, whereby the location information can be registered in the shooting location storage area 23a.

  Here, there are the following two methods for classifying and managing video information using location information.

  (1) A method of managing video information and location information indicating the shooting location in association with each other.

  (2) A method in which location information indicating the shooting location is inserted into video information and managed as one shot image.

First, the method (1) will be described.
The video information photographed by the security camera 12a is transmitted to the video recording device 13a through the photographing cable 18a as analog information by the NTSC (National Television System Committee) system. At that time, the CPU 22 mounted on the security camera 12a reads the location information from the shooting location storage area 23a of the storage unit 23, and this location information is simultaneously sent to the video recording device 13a via the communication cable 17a. To transmit. This location information consists of digital information.

  The CPU 31 mounted on the video recording device 13a compresses video information sent from the security camera 12a via the shooting cable 18a by a predetermined method in the image processing unit 32, and so on. Recording is performed in the recording area 33a. Further, the CPU 31 records the location information sent from the security camera 12a through the communication cable 17a as management information of the video information in the management recording area 33b.

  In this way, the video recording device 13a manages video information and location information as management information in association with each other. When there is a video request from the portable terminal 14 in this state, the security camera 12a reads video information and location information from the video recording device 13a. Then, the video information is modulated into digital information of “1” and “0”, and the location information is added to the modulated video information and transmitted to the mobile terminal 14 through the transmission / reception device 16a.

Next, the method (2) will be described.
As described above, video information taken by the security camera 12a is transmitted to the video recording device 13a as analog information by the NTSC system. At that time, the CPU 22 mounted on the security camera 12a reads the location information from the shooting location storage area 23a of the storage unit 23, inserts the location information into the video information, and sends it to the video recording device 13a.

  In this case, since the video information is analog information and the location information is digital information, a method of adding a management name of the video information by superimposing the digital information on the analog information is used. Specifically, by superimposing location information composed of digital information of “1” and “0” in a vacant time zone in the NTSC signal, a captured video recording area 33a of the storage unit 33 as one captured image. To record.

  Here, when there is a video request from the portable terminal 14, the security camera 12a reads video information from the video recording device 13a. This video information includes location information. Therefore, the video information is digitized and transmitted to the mobile terminal 14 to be given to the mobile terminal 14 together with the location information.

  On the other hand, the mobile terminal 14 receives the video information sent from the security camera 12a and the location information that is management information by the transmitting / receiving device 48. As shown in FIG. 4, the portable terminal 14 includes a filter circuit 49 for extracting location information from the received video information. In the mobile terminal 14, the video information is classified and managed based on the location information extracted by the filter circuit 49.

  Processing of the mobile terminal 14 at this time will be described with reference to FIGS. 5 and 6. FIG. 5 is a diagram showing a relationship between video information and location information of the security video management system in the embodiment. FIG. 6 is a diagram for explaining a video information management method of the security video management system according to the embodiment.

  As shown in FIG. 5, when the CPU 41 mounted on the mobile terminal 14 receives video information including location information from the security camera 12a, the filter circuit 49 extracts the location information from the video information. Then, the CPU 41 creates a video file with the extracted location information as a folder name in the video storage unit 46 so that the video information having the same location name can be managed collectively.

  That is, as shown in FIG. 6, if the location information of the security camera 12 a is now named “Location A”, the video information extracted from the video recording device 13 a is “Location A” in the mobile terminal 14. The folder name is classified and managed. On the other hand, if the location information of the security camera 12b is a name such as “Location B”, the video information extracted from the video recording device 13b is classified and managed by the folder name “Location B” in the mobile terminal 14. Become.

  In addition, since the video information includes the shooting date and time, if this shooting date and time is used as a subfolder, each piece of image information extracted from the same place can be further classified and managed by shooting date and time.

  In the example of FIG. 6, subfolders such as “shooting date / time t11”, “shooting date / time t12”, “shooting date / time t13”, etc. are created under “location A”, and each image information taken out from the video recording device 13a is created therein. Are classified and managed. Similarly, subfolders such as “shooting date / time t21”, “shooting date / time t22”,... Are created under “location B”, and each piece of image information extracted from the video recording device 13b is classified and managed.

  As described above, when a large amount of video information is collected using the mobile terminal 14, each video information is classified and managed on the basis of the location information added to the video information, so that the video information where the video is captured can be obtained. It becomes possible to easily determine whether or not there is.

  In addition, as shown in FIG. 4, even when each video information collected using the portable terminal 14 is centrally managed by the computer 50, where each video information is classified and managed by the location information, where the image is taken. Whether it is video information can be easily determined, and the video information can be used for crime verification.

  In the above embodiment, the video information has been described as being classified and managed. However, for example, various types of information necessary for maintenance such as the operation state and operating conditions of the device can be classified and managed by location information in the same manner as described above. It is.

  In the above embodiment, the case where two cars 11a and 11b are monitored is taken as an example, but the same applies to the case where there are more cars. In addition to a car, a configuration may be adopted in which a security camera is installed in an elevator hall and the video information is monitored.

  Furthermore, the security video surveillance system of the present invention can be applied to places other than elevators as long as security is required.

  In short, the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the components without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
