Description

  The present invention relates to an elevator security system in which a security camera and an authentication device are provided in at least one of an elevator hall and an elevator car.

  In apartment buildings such as condominiums, in principle, residents and their related persons (hereinafter referred to as “residents”) can enter the building, and other persons (hereinafter referred to as “non-related persons”). ) Is usually prohibited from entering buildings from the viewpoint of crime prevention. Therefore, the elevator installed in the building is permitted for residents to use the elevator, but the elevator is prohibited for non-related persons.

  In addition, managers often used to identify residents and non-related parties in the past, but recently there have been an increase in the number of apartment houses that do not have managers because of the reduced labor of managers. An example in which an authentication device is installed in a landing or an elevator car is increasing (see, for example, Patent Document 1). In recent elevator systems, there are many examples of installing a security camera in an elevator hall or an elevator car (see, for example, Patent Document 2).

By the way, the image data from the security camera is projected in real time on a display unit (display) provided in the elevator hall or elevator car, or in the case where a manager room or a monitoring room is installed. Although it is intended to enhance the crime prevention effect, it is further intended to be stored in a recording medium, thereby contributing to the investigation after the crime occurs. When searching and reproducing image data stored in a recording medium, conventionally, the date and time of shooting by a security camera has been used as a search keyword.
Japanese Patent Laid-Open No. 11-349238 Japanese Patent No. 2627455

  However, when the crime or crime-related event occurrence time can be specifically identified, the target image data can be easily obtained by using the above shooting date and time as a search keyword. If not, a huge amount of image data must be reproduced to search for the target image data, and a great deal of labor has to be expended.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an elevator security system capable of performing an efficient search on image data stored in a recording medium.

  As means for solving the above-mentioned problems, the invention according to claim 1 is directed to at least one of the elevator hall and the elevator car, a security camera for photographing the elevator user, and the elevator user. And an authentication device for performing authentication as to whether or not to permit use of the elevator, and further storing image data from the security camera, searching the stored image data based on a predetermined search condition, and displaying it on the display unit In an elevator security system including an image recording device capable of displaying, the image recording device associates an authentication result of the authentication device with image data, and image data based on an input of a search condition including the authentication result. It is characterized by having an image data search means for performing the above search.

  The invention described in claim 2 is characterized in that, in the invention described in claim 1, the authentication result includes either authentication success or authentication failure.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, when the display unit displays the search result of the image data search means, it is an accessory for specifying an elevator user related to an authentication target. Information is also displayed.

  The invention according to claim 4 is the invention according to claim 3, wherein the accompanying information for specifying the elevator user includes an authentication ID registered in advance, the room number of the elevator user, and the name of the elevator user. At least one of them is included.

  According to the present invention, an image recording apparatus that stores image data from a security camera associates an authentication result of an authentication apparatus with image data, and searches for image data based on input of a search condition including the authentication result. Since the data search means is provided, an efficient search can be performed on the image data stored in the recording medium.

  FIG. 1 is a block diagram showing the configuration of the embodiment of the present invention. A security camera 1, an authentication device 2, and an image recording device 3 are installed at the elevator hall. The image recording apparatus 3 includes an image data recording unit 4, a recording medium 5, an image data search unit 6 having an authentication result association unit 7, and a display control unit 8. The image data recorded on the recording medium 5 is displayed on the screen of the display unit 9 under the control of the display control means 8. The remote controller 10 can output several search keywords to the image data search means 6 as search conditions.

  In the present embodiment, the security system shown in FIG. 1 is described as being installed at the elevator hall, but a security system having the same configuration can also be installed in the elevator car. Alternatively, the security system shown in FIG. 1 can be installed in both the elevator hall and the elevator car.

  Next, the operation of FIG. 1 will be described. It is assumed that an elevator user approaches the authentication device 2 and tries to get on the elevator and performs a predetermined operation. The authentication result of the authentication device 2 at this time is sent to an elevator control device (not shown). If the authentication result is “success”, the elevator control device responds to the hall call by the elevator user, while if the authentication result is “failure”, the elevator control device responds to the hall call by the elevator user. do not do.

  The security camera 1 starts the photographing operation of the elevator user when the elevator user starts the operation on the authentication device 2, and if the authentication result is “success”, the elevator user gets into the elevator car. The photographing operation is finished when the elevator door is closed. On the other hand, when the authentication result is “failure”, the photographing operation is terminated when a predetermined time has elapsed. The image data from the security camera 1 at this time is output and stored in the image recording device 3, but is output directly to the display unit 9 at the same time. Therefore, the display unit 9 displays the elevator user in real time. Further, the authentication result of the authentication device 2 at this time is sent to the authentication result association means 7 of the image data search means 6.

  The image data output from the security camera 1 to the image recording device 3 is input to the image data recording means 4. The image data recording means 4 records this image data on the recording medium 5. At this time, the image data recording unit 4 outputs the data address of the image data in the recording medium 5 to the authentication result association unit 7. The authentication result associating means 7 associates the authentication result for each elevator user with the data address from the image data recording means 4 and stores data relating to the association in its own memory. Such an operation is repeated every time each elevator user performs an authentication operation on the authentication device 2.

  Now, when a criminal case occurs in a building, it is necessary to check the use record of the elevator as investigation materials. In such a case, the elevator manager (or a person corresponding to the manager) performs a predetermined operation with the remote controller 10. Then, an image data search command is sent from the remote controller 10 to the image data search means 6, and the image data search means 6 instructs the display control means 8 to display a search menu screen based on this.

  FIG. 2A is a display example of the search menu screen on the display unit 9 at this time, and four buttons of “authentication success”, “authentication failure”, “all”, and “time designation” are displayed. . “Authentication success” is a button that is clicked when displaying image data of an elevator user who has been authenticated as a resident who is permitted to enter or leave the building. “Authentication failure” This button is clicked when trying to display image data of an elevator user who has been authenticated as a non-participant who is not allowed to enter and exit. “All” is an elevator for both “authentication success” and “authentication failure”. The button is clicked when the user is to be displayed, and the “time designation” is a button that is clicked when the elevator user is to be displayed based on the shooting time of the security camera 1 instead of the authentication result.

  If the elevator administrator clicks the “all” button, for example, an image specified by “date”, “time”, “result”, and “authentication ID” as shown in FIG. A list of data is displayed on the screen of the display unit 9. This “authentication ID” is displayed as accompanying information for identifying the elevator user related to the authentication target, so that the elevator administrator can easily know who the elevator user is. .

  For example, when an elevator administrator wants to check the image data of an elevator user whose authentication ID is “205”, the photograph is taken at 10:40:30 on January 1, 2004 as shown in FIG. The authentication result is “successful” and the authentication ID is “205”.

  Then, based on the selected image data, a moving image of the elevator user standing at the elevator hall is displayed on the screen of the display unit 9 as shown in FIG. At this time, the shooting start date and time, the authentication result, and the authentication ID are displayed at the bottom of the screen. As a result, it is possible to confirm whether the elevator user is truly a person related to the authentication ID “205”, and its state and behavior.

  According to the system configuration of FIG. 1 described above, the authentication result association unit 7 of the image data search unit 6 in the image recording apparatus 3 stores the image data from the security camera 1 in the recording medium 5 by the image data recording unit 4. When this is done, the image data and the authentication result of the authentication device 2 are associated with each other, and the image data search means 6 performs a search operation based on the input of the search condition including the authentication result. The elevator administrator can efficiently search the image data stored in the recording medium 5, and can extract desired image data quickly and easily and reproduce it.

  In the above embodiment, when desired image data is reproduced on the screen, as shown in the lower part of FIG. 2C, the authentication ID of the elevator user is displayed as accompanying data. It is possible to install an authentication device management server to display various data as accompanying data. For example, the elevator user's room number may be displayed, such as “Building A, Room 205”, or the sex, age, and occupation of the elevator user may be displayed, such as “Male, 45 years, office worker”. Also good. Alternatively, it is also possible to display the name of the elevator user itself. Thereby, when it is going to use image data for the criminal case investigation etc., the efficient search work according to the progress of the investigation can be performed.
