DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the invention will be described with reference to the drawings.
FIG. 1 is a diagram showing a configuration of an embodiment of a security status setting system according to the present invention, in which 1 is a security status setting device, 2 is a main control unit, 3 is a communication control unit, 4 is a card reader, 5 is a warning button, 6 is a release button, 7 is a display control unit, 10 is a monitor, 11 is a monitoring camera (hereinafter simply referred to as a camera), and L is a communication line.
[0007]
As shown in FIG. 1, the security state setting system includes a security state setting device 1, a monitor 10, and a camera 11. The security state setting device 1 is installed in the vicinity of an indoor entrance of a building where a security system is constructed. The monitor 10 is composed of a display device capable of displaying an image, such as a CRT or a liquid crystal display device, and is disposed in the vicinity of the security state setting device 1. When the camera 11 is a color camera, the monitor 10 is naturally composed of a display device capable of displaying a color image. The camera 11 is installed so that the vicinity of the outside of the doorway can be imaged.
[0008]
In this security status setting device 1, when the security status is switched from the unlocked status to the alert status, or from the alert status to the unlocked status, the card operation, that is, the card in which the ID number is written is inserted into the card reader 4. The first stage operation of causing the main control unit 2 to identify the ID number and the second stage operation of pressing the warning button 5 or the release button 6 after the ID number is identified by the main control unit 2 Has been made to do the operation.
[0009]
As a first-stage operation method for causing the main control unit 2 to identify the ID number, in addition to the card operation as shown in FIG. 1, a method of inputting the ID number with a numeric keypad, A non-contact information storage medium of a so-called on-chip coil system in which a ROM storing an ID number is connected to one end of an antenna coil in a non-contact automatic identification code reader (RFID (Radio Frequency Identification) reader) that transmits A method of approaching is also known, and any method may be used as long as it allows the main control unit 2 to identify the ID number. In this embodiment, a method by card operation is adopted. . Since RFID readers and on-chip coil type non-contact information storage media are well known, detailed description thereof will be omitted.
[0010]
As shown in FIG. 2, the main control unit 2 determines the ID number, the number of the warning area corresponding to the ID number, and the current security status of the security area, that is, the current security status. A guard state table (not shown in FIG. 1) is provided that is associated with a guard state value that indicates whether the state is in the released state. Here, it is assumed that the guard state value is “1” when in the alert state, and the guard state value is “0” when in the released state.
[0011]
The communication control unit 3 is for communicating with a security device (not shown in FIG. 1) via the communication line L.
When a card-like storage medium such as an IC card or an optical card is inserted, the card reader 4 performs processing to read data such as an ID number written on the card-like storage medium and pass it to the main control unit 1. . Here, an IC card is used. Therefore, in the following description, it is assumed that the card reader 4 is an IC card reader.
The security button 5 is a button that is operated in the second stage when setting the security state from the release state to the security state. The release button 6 is the second stage when switching the security state from the security state to the release state. This is a button to be operated, and each is composed of a push button switch.
The display control unit 7 receives an image pattern created by the main control unit 2 and a video signal from the camera 11, and receives a control signal for controlling the display screen from the main control unit 2. This point will be described later.
[0012]
Hereinafter, the operation of the security state setting system shown in FIG. 1 will be described. First, the overall configuration and operation of the security system using the security state setting system shown in FIG. 1 will be schematically described with reference to FIG. Here, a case of a security system built in a tenant building will be described as an example.
[0013]
The security device 20 and the security state setting device 1 are connected by a communication line L. A security sensor is connected to the security device 20, and the security device 20 outputs to the output device.
As the security sensor, a heat ray sensor for detecting movement of a person, an open / close detection sensor for detecting that a door or a window is opened, and the like are used. All the security sensors are assigned different addresses.
As output devices, there are intimidating devices such as sirens and bells to threaten intruders when an abnormality occurs, and reporting devices for reporting abnormalities and scheduled reports to the centralized monitoring center of the security company by telephone line Used.
[0014]
In order to perform security, the total number of security areas, the correspondence between the security area number and which tenant is in which security area, and the name of the tenant, and which address the security sensor is installed in each security area. Various information such as information on the correspondence between the security area to be shown and the security sensor address, information on the current security status of each security area, etc. are necessary, but here all the information necessary to perform these security, It is assumed that the security device 20 is set and registered in advance. As will be described later, information related to the security status of each security area is notified from the security status setting device 1.
[0015]
The security device 20 performs security processing according to the security status of the security area and the security sensor status. That is, even if it is detected that a security sensor has been issued, if the security area where the security sensor is installed is in a released state, it is not determined that an abnormality has occurred, but the security sensor has issued a report. When the warning area where the security sensor is installed is in a warning state, the security device 20 determines that an abnormality has occurred and instructs the output device to output. As a result, the threatening device operates, and an abnormality report is sent to the central monitoring center of the security company.
The above is the general configuration and operation of the entire security system.
[0016]
Next, the operation of the security state setting system shown in FIG. 1 will be described with reference to the flowchart shown in FIG.
When the card operation is not performed, the main control unit 2 generates and sends a predetermined image pattern to the display control unit 7 and sends a control signal instructing to select an image pattern from the main control unit 2. Notice. The screen at this time will be referred to as a normal screen. Therefore, at the normal time when the card operation is not performed, a predetermined normal screen generated by the main control unit 2 is displayed on the monitor 10 (step S1). As an image at this time, for example, an image for guiding an operation such as “insert card” may be used, or any other image may be used. Furthermore, the entire display screen may be a predetermined color such as black so that no image is displayed.
[0017]
In a state where the normal image is displayed on the monitor 10, the main control unit 2 waits for a card operation (step S2). Now, when an employee of a tenant inserts an IC card into the card reader 4 and performs a card operation, the card reader 4 reads the ID number from the IC card and passes it to the main control unit 2. As a result, the main control unit 2 recognizes that the card operation has been performed.
[0018]
Then, when the main control unit 2 recognizes that the card operation has been performed (in the case of yes in step S2), the main control unit 2 identifies the ID number (step S3). In this ID number identification process, the main control unit 2 refers to the security state table and, if the ID number is registered in the security state table, recognizes it as a regular ID number and determines in step S4. If it is not registered, it is recognized as an invalid ID number, the ID number is ignored, and the process returns to step S1.
[0019]
When the ID number received from the card reader 4 is a legitimate ID number (in the case of yes in step S3), the main control unit 2 refers to the security state table, and the security area corresponding to the ID number is currently warned. It is determined whether or not it is in a state (step S4). And when the said warning area is a warning state now (in the case of yes in step S4), the main-control part 2 judges that it is going to switch a security state from a warning state to a cancellation | release state, and this After that, the operation of the release button 6 is validated only until the release button 6 is pressed or until time-out in step S7.
[0020]
At this time, the main control unit 2 generates an image pattern of operation guidance for setting the release state and supplies the generated image pattern to the display control unit 7. After step S1, the control signal given to the display control unit 7 is not changed, and an instruction to select an image pattern from the main control unit 2 is given, so that the operation guidance screen is displayed on the monitor 10. . The operation guidance screen in this case may be a character pattern that guides an operation for setting a release state such as “Pressing the release button releases the security”.
[0021]
Then, the main control unit 2 waits for the release button 6 to be pressed (steps S6 and S7), and when a predetermined time elapses without the release button 6 being pressed, the main control unit 2 determines that there is no intention to operate. Timed out (if yes in step S7), the process returns to step S1, but if it is detected that the release button 6 has been pressed before the timed out (if yes in step S6), the warning in the security status table The security status value of the area is changed from “1” to “0”, and further, the security device 20 is notified that the security area is set to the release status (step S8), and the process returns to step S1. When the normal screen is displayed after returning from step S8 to step S1, the card operation is performed again to switch the security state. Note that the timeout time can be arbitrarily set, and the same applies to this point.
[0022]
The above is a case where the warning area is in a warning state in the determination in step S4. However, when the warning area is currently in a released state (in the case of no in step S4), the main control unit 2 displays the security state. It is determined that switching from the released state to the alert state is made, and the operation of the alert button 5 is validated only until the alert button 5 is pressed after this time or until a time-out occurs in step S11.
[0023]
At this time, the main control unit 2 generates and supplies an image pattern of operation guidance for setting the alert state to the display control unit 7, and the image pattern and the video signal from the camera 11. Is notified (step S9). The operation guidance screen in this case may be a character pattern that guides an operation for setting a warning state such as “Pressing a warning button will start security”. As a result, an image pattern for operation guidance, for example, a character pattern as described above is superimposed on the image near the outside of the doorway taken by the camera 11 on the monitor 10, so that the card operation was performed. The operator can know the situation near the outside of the entrance / exit by observing the screen of the monitor 10.
[0024]
Then, the main control unit 2 waits for the warning button 5 to be pressed (steps S10 and S11), and when the predetermined time has passed without the warning button 5 being pressed, the main control unit 2 determines that there is no willingness to operate. Timed out (in the case of yes in step S11), the process returns to step S1 to display the normal screen, but it is detected that the warning button 5 has been pressed before the time out (in the case of yes in step S10), Change the security status value of the security area in the security status table from “0” to “1”, and further notify the security device 20 that the security area has been set to the security status (step S12). Returning to step S1, the normal screen is displayed. When the normal screen is displayed from step S11 to step S1, the card operation is performed again to switch the security state.
[0025]
As described above, according to this security state setting system, when switching from the release state to the warning state is set, the image captured by the camera 11 is always displayed on the monitor 10, and the operation of the warning button 5 is performed on the monitor 10. The image is valid only during the period when the image captured by the camera 11 is displayed. Therefore, when the operator confirms the safety near the outside of the entrance / exit by observing the screen of the monitor 10, before the time-out in step S11. It is only necessary to press the warning button 5, and when anxiety arises in the situation near the outside of the entrance / exit, it is possible to take appropriate measures such as contacting the security company by telephone without pressing the warning button 5.
[0026]
As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, A various deformation | transformation is possible. In short, when it is determined to set the alert state, the surveillance camera image can be displayed to check the situation near the outside of the entrance and exit, and the surveillance camera image is set to the alert state only after it is displayed on the monitor. Therefore, any configuration can be used as long as the second stage operation cannot be performed.
[0027]
For example, in the above embodiment, the alert button 5 and the release button 6 are configured by push button switches, but the monitor 10 is configured by a display device having a touch panel on the front of the screen. In this case, it is possible to adaptively display a touch button for performing the second stage operation on the monitor 10. Specifically, the release touch button may be displayed on the monitor 10 in the process of step S5 in FIG. 4 and displayed until it is touched or timed out. Similarly, in the process of step S9 in FIG. The alert touch button may be superimposed on the image from the camera 11 and displayed until it is touched or timed out.
In the above embodiment, the card reader 4 is used to perform the first stage operation for identifying the ID number. However, the monitor 10 is constituted by a display device having a touch panel on the front surface of the screen. In this case, it is possible to display a numeric keypad on the normal screen and input an ID number using this numeric keypad.
Further, a speaker may be provided and a voice message may be issued using a voice synthesis technique.
