Abstract

PROBLEM TO BE SOLVED: To provide a closed circuit TV CCTV system with sophisticated functions supervising a supervisory object area such as rivers and mountainous road that provides an optimum image depending on the meteorological condition of the supervisory object area. SOLUTION: Sensors sensing the meteorological condition are provided in the supervisory object area and the CCTV system conducts transmission and direction control of the image.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a CCT for monitoring an image.
The present invention relates to improvement of a V device.

[0002]

2. Description of the Related Art Heretofore, CCTV devices and weather sensors have been separately installed and have no association. Therefore,
The image was independently displayed on a dedicated monitor, and the weather data was also displayed on the dedicated display. Therefore, each function was independent and had no association.

[0003]

In disaster prevention monitoring of rivers and roads, especially in the event of a disaster, the work is complicated and an appropriate judgment is required in a short time. Therefore, there is a need to quickly and accurately notify the situation of the site to the observer.

[0004]

Therefore, in the present invention,
The data of the weather information obtained by the weather sensor is collected by the CCTV device, and when there is an abnormality, the camera is automatically moved to the location to enable visual monitoring of the image of the abnormal point. The imaging direction of the camera, the zoom ratio, and the like are preset. Also, the numerical values of the weather data at that time are superimposed and displayed in accordance with the corresponding images. This allows the observer to accurately grasp the abnormal location and the weather data indicating the situation simply by monitoring the television monitor screen.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. Reference numeral 1 denotes a CCTV camera for capturing an image of a monitoring target. Reference numeral 2 denotes a lens attached to the camera 1 for photographing an image, and has a preset and remote zoom function. Reference numeral 3 denotes a swivel head, which can freely move the direction of the camera by a swivel function, and can further move according to the preset value. Thus, C
The CTV camera system has a preset function, and can move to a subject specified in advance. Reference numeral 4 denotes a preset control unit, which is a device for moving the lens and the swivel head to designated positions. Reference numeral 9 denotes a control device for collectively controlling these CCTV devices. Therefore, when a command is given to the CCTV control device, the camera 1 changes the imaging direction to a specified subject and shoots an object. Reference numeral 5 denotes a weather sensor, which measures wind direction, wind speed, rainfall, visibility, temperature, and the like. Reference numeral 6 denotes a device for receiving weather data, which outputs data from the weather sensor 5 as numerical information. Reference numeral 7 denotes a weather data setting unit that sets a reference value for determining an abnormality. Reference numeral 8 denotes a weather data comparison unit which outputs a warning as an abnormal situation when the data from the weather sensor 5 is detected with a numerical value exceeding the value set by the weather data setting unit 7. When the weather data comparing unit 8 outputs an alarm, the CCTV control device 9 controls the wind speed,
The data is taken in for three points, rainfall and visibility. Further, a command is issued to the preset control unit 4 to move the camera 1 in the imaging direction set in advance and to image the situation. The camera 1 follows this control, and the imaging direction, zoom ratio,
Focus and the like are controlled, and an image of a situation at a predetermined place is taken.

On the other hand, the numerical value of the weather data is sent to the character generator 10. Then, the data is displayed on the CCTV monitor 11 simultaneously with the image of the site as character data. In this way, according to the present invention, the image of the site where the abnormal situation has occurred and the weather data at that position can be confirmed on one screen, so that a quick decision can be made. Further, it is possible to prevent the occurrence of an accident in which the correspondence between the weather data and the image is mistaken.

[0007]

As described above, according to the present invention,
In a monitoring system in a river or a mountainous area, when an abnormal value of weather data occurs, an image of the point can be immediately visually confirmed, thereby exerting a great operational effect in a monitoring operation.
