Abstract

PURPOSE:To monitor surely even with a small number of TV cameras though places to be monitored are in a wide range or include plural intricated positions, by providing a central controller with a monitor device, a radio communication equipment, and a moving car controller. CONSTITUTION:An attended running track 3 runs automatically on a preliminarily set course while detecting ferrite mark bodies installed on surfaces of roads by a magnetic sensor on a basis of commands from a central controller 2 and rotates and drives a rotating stage to scan a preliminarily set angle range by a TV camera 4. Images picked up by the TV camera 4 are transmitted to the central controller 2 through mutual communication between radio communication equipments 6 and 7 and is displayed on a TV monitor 8. An operator monitors pictures on the TV monitor 8 to detect the presence/absence of invaders from the external or the presence/absence of the occurrence of an abnormal state. On demand a moving truck controller 9 is operated to control turning, stop, and start of the unattended truck 3, rotation and zooming of the TV camera 4, etc.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a monitoring system using a TV camera in facilities and buildings such as airports, factories, and buildings.

[Conventional technology]

BACKGROUND ART A central monitoring system using a plurality of TV cameras has conventionally been used in facilities and buildings such as airports, factories, and warehouses to detect intruders from the outside or abnormal situations such as fires.

As is well known, this system involves monitoring each of a plurality of TV cameras installed at key locations from a central monitoring center.

[Problem that the invention seeks to solve]

However, when the area to be monitored is wide or there are complex areas such as indoors, there are likely to be blind spots that cannot be monitored. There is no choice but to increase the number of TV cameras, which has the disadvantage of requiring a very large number of TV cameras. To provide a surveillance system capable of reliably monitoring even a small number of TV cameras even in a complicated place.

[Means for solving problems]

The present invention consists of a mobile monitoring console that automatically travels along a pre-installed taxiway and a central control device installed in a monitoring center.The mobile monitoring console is equipped with a TV camera and a wireless communication device that communicates with the central control device. The central control system is equipped with a monitor device that displays video signals from the TV camera mounted on the mobile surveillance vehicle, a wireless communication device that communicates with the mobile surveillance console, and a control device that controls the operation of the mobile surveillance console. This is a monitoring system featuring:

[Effect]

In the present invention, a TV camera for monitoring, which was conventionally fixed at one point, is mounted on a mobile monitoring console, and the mobile monitoring console is automatically run along a preset course, thereby covering a wide area with a small number of TV cameras. At the same time, the TV camera is moved to a place where a fixed camera would be in a blind spot, and the images captured by the TV camera are monitored at the monitor center.

Furthermore, as necessary, more detailed monitoring is performed by finely adjusting the position of the moving vehicle, the direction of the TV camera, and zooming the TV camera under control from the control device within the central control device.

〔Example〕

Fig. 1 shows an embodiment of the system configuration of the present invention.
As shown in the figure, the monitoring system of this embodiment is broadly divided into a mobile monitoring console 1 and a central control device 2 installed at a monitoring center.
It consists of The mobile monitoring console 1 is equipped with a TV camera 4 and an on-vehicle wireless communication device 6 on an unmanned traveling trolley 3, and the central control device 2 controls the operation of the fixed wireless communication device 7, the TV monitor 8, and the mobile monitoring console, as well as the operation of the onboard equipment. It consists of a control device 9 that controls the.

As shown in FIG. 2, the mobile monitoring console 1 includes a wireless communication device 6 mounted on an unmanned vehicle 3, and a TV camera 4 mounted on a rotation stage 5 so as to be rotatable in a horizontal plane and a vertical plane. be.

Based on the instructions from the central control device 2, the unmanned traveling trolley 3
A magnetic sensor 10 detects a ferrite marker 11 installed on the road surface, and the vehicle automatically travels along nine preset routes. At the same time, the rotary stage 5 is driven to rotate, and the TV camera 4 scans a preset angular range. Therefore, the 30 travel routes of unmanned trolleys and the TV
By selecting the scanning angle range of the camera 4, the necessary range can be reliably monitored even in a wide range or a complicated route.

Images captured by the TV camera 4 are sent to the central control device 2 through mutual communication between the wireless communication devices 6 and 7, and are displayed on the TV monitor 8 of the central control device 2.

The operator can monitor the TV monitor 8 of the central control device 2 to know whether there is an intruder from outside or whether an abnormal situation has occurred. Furthermore, if necessary, the mobile vehicle control device 9 is operated to control the direction change, stop, and start of the unmanned vehicle 3, and the rotation and zooming of the TV camera 4, thereby monitoring the situation in more detail. is also possible.

In the above embodiments, a ferrite marker was used to guide an unmanned vehicle, but the guidance method is not limited to the above embodiments, and may be any well-known guidance method depending on the application, such as a guidance cable method or a light reflection method. A tape method or the like may also be applied.

Furthermore, if an infrared camera is used as the TV camera, nighttime monitoring is also possible.

Furthermore, by providing various additional functions to the mobile monitoring console and the central control device, it is possible to quickly respond to detected abnormal situations. For example, by image-processing signals from a TV camera and detecting objects moving at a certain speed or higher relative to the background, intruders from the outside can be automatically detected and an alarm can be issued.

Furthermore, if a fire extinguisher is mounted on a mobile monitoring table and can be controlled from a central control system, extinguishing operations can be carried out at the same time as a fire is discovered.

〔Effect of the invention〕

As described above, according to the present invention, in a surveillance system using TV cameras, even when the surveillance range is wide or includes a complex area, it is possible to monitor by using a minimum number of TV cameras. easily wherever you need it,
Moreover, it has the effect of making it possible to perform monitoring reliably and quickly responding to abnormality detection.
