DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a building provided with a building security system according to an embodiment of the present invention.

In FIG. 1, A is a building, and this building A has four floors from 1F to 4F. Reference numeral 1 denotes a security monitoring device, which includes means for communicating information for security monitoring. 2 is an elevator control device for controlling the operation of the elevator, 3 is an elevator car, and 31 is a monitoring camera for monitoring the inside of the elevator car and each floor.

Reference numeral 4 denotes a surveillance room; 41, an image display device for displaying an image of the surveillance camera 31 installed in the car;
Reference numeral 2 denotes an image recording device for recording an image of the monitoring camera 31;
Reference numeral 3 denotes a camera operation device for operating the photographing angle and mounting position of the monitoring camera 31; 44, an alarm device for generating an alarm when a building is abnormal; 45, an elevator operation panel capable of arbitrarily controlling the operation of a car; An intrusion detector 52 is provided at the landing entrance to detect an intruder on each floor (only the third floor is shown here). Reference numeral 52 denotes a security setting device for starting and releasing security settings.

The elevator control device 2 and the alarm device 44
The elevator operation panel 45, the intrusion detector 51, and the security setting device 52 are connected to the security monitoring device 1, respectively. The video recording device 42 and the camera operation device 4
3 are connected to the monitoring camera 31, the video display device 41 is connected to the video recording device 42, and the alarm device 44
Is connected to the video recording device 42 and the camera operation device 43.

The security monitoring device 1 includes a security setting determining means 11 for determining whether or not a security setting is being performed by a security setting device 52 installed at an arbitrary location, and an intrusion detector 51 installed on each floor for intrusion of a person. Intrusion detection / judgment means 12 for judging whether or not an error has been detected, communication means 13 for the elevator control device 2 for causing the elevator to perform a preset operation, and communication means 14 for instructing the alarm device to generate an alarm. ing.

The video recording device 42 is a monitoring camera 3 installed in the car 3 so as to monitor the inside of the car 3 and each floor.
One image is recorded and displayed on the image display device 41.

The surveillance camera 31 is provided with a mechanism for changing the photographing angle and the camera mounting position. It is provided with means capable of performing operations such as moving the photographing angle and mounting position. Although not shown, the alarm device 44 receives an instruction to generate an alarm from the security monitoring device 1 and generates an alarm.
2 is provided with communication means for instructing recording start and recording stop of the video.

Further, an elevator operation panel 45 in the monitoring room 4
Although not shown in the figure, there is provided a means capable of performing all operations such as operation, suspension, opening and closing of a door of an elevator car 3 via a security monitoring device 1 and an elevator control device 2.

Next, the operation of the present embodiment when a suspicious person actually enters will be described with reference to the flowchart of FIG.

The security setting device 52 sets the third floor, for example, to the security setting state (S10). When the intrusion detector 51 on the third floor detects intrusion of a person at the entrance 6 in the security setting state (S20), the security monitoring device 1 determines that there is an intruder, and issues an alarm to the alarm device 44 (S30). ).

The alarm device 44 causes the video recording device 42 to start recording an image (S40), and transmits an alarm generation signal to the camera operation device 43, and the camera operation device 43
Moves the surveillance camera 31 to the optimal photographing angle and mounting position when photographing the third floor 3F set in advance (S5).
0).

On the other hand, the security monitoring device 1 sends a signal to the elevator control device 2 when the intrusion detector 51 detects that a person has entered.
Instruct floor 3F to move car 3 and open the door (S
60). The car 3 moves to the third floor 3F where the intrusion detector 51 has detected the intrusion of a person, and after opening the door, the intrusion detector 51.
Detects that the intruder has disappeared,
The state is maintained until it is determined that there is no intruder (S70).

When the security monitoring device 1 determines that no intruder has left, the door of the car 3 is closed and the vehicle is on standby on the same floor, and the alarm device 44 stops the recording of the video recording device 42 (S8).
0).

When the door of the car 3 is opened and the weight sensor of the car 3 (not shown) detects that a person assumed to be an intruder has got on the elevator (S90), the security monitoring device 1 turns on the car. The intruder can also be detained by closing the door 3 and suspending the operation of the elevator (S100).

The monitoring room 4 can be installed in a remote place by using a telephone line for transmitting and receiving signals between the device installed in the monitoring room 4 and other devices.

The operation of the elevator can be arbitrarily manually operated from the monitoring room. For example, the intrusion detector 51 detects that the intruder has disappeared, and the security monitoring device 1 determines that the intruder has disappeared. Even if it is determined, the door is kept open and the monitoring is continued, or the floor other than the floor where the intrusion detector 51 detects the intrusion of a person is manually operated by the elevator operation panel 45, and the camera operation device 43 is used. It is also possible to operate and monitor the monitoring camera 31.

Although the security setting device is provided in this example, the same operation can be performed in an office building or the like where no person enters or leaves, such as at night, even without the security setting device. . In addition, if the surveillance camera is also used as a commonly used in-car security camera, the cost can be reduced.

[0024]

As described above, according to the present invention, it is possible to efficiently monitor the status of all floors where elevators are in service with a minimum number of surveillance cameras. This not only reduces equipment costs such as surveillance cameras,
Construction costs can be reduced by reducing wiring work related to equipment installation.
