BEST MODE FOR CARRYING OUT THE INVENTION
Embodiment 1 FIG.
FIG. 1 is a diagram showing a configuration of an entry / exit management system according to the present invention. As shown in FIG. 1, the entry / exit management system includes a card reader 1 installed outside the door, a switch 2 installed inside the door, a camera 5 monitoring the outside of the door, and a video signal of the camera 5 received. Then, while there is an image change in a predetermined detection area, an image change detector 6 for outputting a detection signal, and a detection area setting for arbitrarily setting an image range (detection area) in which the image change detector 6 detects a change. A warning signal according to the state of the section 7 (which may be provided in the camera 5), the OK signal (registration confirmation signal) from the card reader 1, the ON signal from the switch 2, and the detection signal from the image change detector 6. The control unit 3 generates a warning signal and outputs a warning signal in response to a warning signal.
[0008]
FIG. 2 is a diagram showing an example of setting a detection area in the first embodiment of the present invention. In general, the detection area is set so as to include the card reader 1 outside the door. In this area setting, it is preferable to set such that a person other than a pedestrian (people entering and leaving the room) does not enter the detection area as much as possible. In FIG. 2, it is indicated by a thick wavy line.
[0009]
FIG. 3 shows a timing chart according to the first embodiment of the present invention. The operation will be described according to the timing chart. The door is reflected on the camera 5, the video signal is transmitted to the image change detector 6, and the pedestrian moves on the door. When approaching and entering the image range of the detection area previously set by the detection area setting unit 7, the image change detector 6 starts outputting a detection signal to the control unit 3 (timing 1). A passerby operates the card with the card reader 1, and if the card is registered in advance, the card reader 1 outputs an OK signal (registration confirmation signal) to the control unit 3 (timing 2). When the pedestrian opens the door and passes outside the detection area, the image change detector 6 stops outputting the detection signal to the control unit 3 (timing 3). Here, if the time from timing 2 to timing 3 exceeds the predetermined time Ta, the control unit 3 outputs an alarm signal and causes the buzzer 8 to output an alarm output (timing 4).
[0010]
When a pedestrian approaches the door and enters the image area of the preset detection area, the image change detector 6 starts outputting a detection signal to the control unit 3 (timing 5). Thereafter, if the passerby does not operate the card with the card reader 1 or operates the card but the card is not a registered card, the card reader 1 does not output an OK signal to the control unit 3 (timing 6). Even if the predetermined time Tb has elapsed from timing 5, if there is no input of the OK signal, the control unit 3 causes the buzzer 8 to output an alarm output (timing 7).
[0011]
When the passerby presses the switch 2 inside the door, the switch 2 outputs a switch ON signal to the control unit 3 (timing 8). When the pedestrian opens the door and goes outside, it enters the image area of the detection area, and the image change detector 6 starts outputting a detection signal to the control unit 3 (timing 9). When the pedestrian leaves and goes out of the detection area, the image change detector 6 stops outputting the detection signal to the control unit 3 (timing 10). Here, if the time from timing 8 to timing 10 exceeds the predetermined time Tc, the control unit 3 causes the buzzer 8 to output an alarm output (timing 11).
[0012]
As described above, based on the video signal of the camera monitoring the outside of the door, the image change in the predetermined detection area is detected by the image change detector and transmitted to the control unit, so that the traffic can be controlled. The entry / exit management can be performed by grasping the traffic state (entrance / exit state) of a person (entrance / exiter).
[0013]
Embodiment 2 FIG.
Further, in the entry / exit management system according to another embodiment of the present invention, the detection area setting unit 7 in FIG. 1 sets the detection area of the camera 5 to an area where the open / closed state of the door can be detected.
[0014]
FIG. 4 is a diagram showing an example of setting a detection area according to the second embodiment. In general, a camera shooting area is set so as to include a card reader 1 outside a door. Among them, the upper part of the door is set as the detection area of the camera. By setting the detection area of the camera at the top of the door, it is difficult to detect even if a pedestrian passes in front of the door, so that it is easy to detect only the opening of the door.
[0015]
FIG. 5 shows a timing chart according to the second embodiment of the present invention. The operation will be described according to the timing chart. If a passerby operates a card with the card reader 1 and the card is registered in advance, the card reader 1 An OK signal (registration confirmation signal) is output to the control unit 3 (timing 1). When a pedestrian opens the door and passes, the image in a preset image range (detection area) changes due to the opening of the door, so that the image change detector 6 starts outputting a detection signal to the control unit 3 (timing 2). . Thereafter, when the door closes and the detection area no longer changes, the image change detector 6 stops outputting the detection signal to the control unit 3 (timing 3). Here, if the time from timing 1 to timing 3 exceeds the predetermined time Ta, the control unit 3 outputs an alarm signal and causes the buzzer 8 to output an alarm output (timing 4).
[0016]
When the passerby presses the switch 2 inside the door, the switch 2 outputs a switch ON signal to the control unit 3 (timing 5). When the pedestrian opens the door and goes outside, the image in the preset image range changes due to the opening of the door, so that the image change detector 6 starts outputting a detection signal to the control unit 3 (timing 6). When a pedestrian opens and passes through the door and closes the door, the image in the preset image range (detection area) does not change, so the image change detector 6 stops outputting the detection signal to the control unit 3. (Timing 7). Here, when the time from timing 5 to timing 7 exceeds the predetermined time Tc, the control unit 3 causes the buzzer 8 to output an alarm output (timing 8). When the door is opened and there is a change in the detection area without the output of the OK signal from the card reader 1 and the switch ON signal from the switch 9, the image crossing detector 6 changes the detection signal to the control unit 3. (Timing 9), whereby the control section 3 causes the buzzer 8 to output an alarm output (timing 10).
[0017]
In this way, based on the video signal of the camera that monitors the outside of the door, the image change detector detects the image change of the detection area set in advance so that the open state of the door can be detected and transmits it to the control unit. Because it is made possible, the opening / closing state of the door can be grasped and entry / exit management can be performed.
[0018]
【The invention's effect】
As described above, according to the present invention, a card reader that is provided outside the door and generates a registration confirmation signal when the card is a pre-registered card, and a preset detection for grasping the state of the entering / leaving person A camera that monitors the outside of the door including the area and supplies a video signal, and an image change detector that generates a detection signal while detecting an image change in the detection area based on the video signal from the camera. A control to generate an alarm signal when the detection signal is present even if a predetermined time has elapsed after receiving the registration confirmation signal, or when the registration confirmation signal is not present even after a predetermined time has elapsed after receiving the detection signal. And an entry / exit management system. Further, when the detection area is an area for grasping the opening / closing state of the door, if the detection signal is present or the registration confirmation signal is not received even if a predetermined time has elapsed after receiving the registration confirmation signal. However, if the detection signal is present, an alarm signal is generated. Thus, entry / exit management can be performed without using an electric lock.
