Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an event-linked station service monitoring system using a turning camera, and more particularly to an operation control of a camera for photographing a railway-specific monitoring target.

[0002]

2. Description of the Related Art In recent years, in the railway industry, many railway companies have been trying to save human resources and improve the working conditions of station staff.
Railway stations are becoming unmanned, the number of station staff per station is being reduced, and such plans are being formulated. As a countermeasure, railway companies have introduced station equipment such as automatic ticket vending machines, automatic ticket gates, and automatic checkout machines, and have adopted a station service remote monitoring system that remotely controls these station equipment. .

The station service remote monitoring system includes, for example, a center monitoring device installed at one monitoring center (manned station or maintenance center, etc.) and a local monitoring device installed at a plurality of monitored stations (unmanned stations, etc.). By controlling video and audio and remotely controlling station equipment (ticket vending machines, checkout machines, ticket gates, etc.) from the center monitoring device through the local monitoring device, even unmanned stations and manned stations It provides a service that is almost equivalent to (for example, JP-A-2000-21)
No. 7162).

[0004]

However, according to the above-mentioned conventional station service remote monitoring system, when an abnormality or failure occurs in a controlled device such as a station service device or an intercom, an alarm display is displayed by an operator. After confirming, he had to turn the camera toward that location. That is,
In the system of the conventional example, the operator must manually operate the camera every time an alarm is displayed on the device to be controlled, which is cumbersome and troublesome for the operator. Efficiency was not very good.

[0005] As a countermeasure, it is conceivable to install a camera for each of all the controlled devices. However, in this case, the number of cameras increases in proportion to the number of the controlled devices, thereby increasing the maintenance and inspection time. In addition, there has been a problem that the work time increases and the cost becomes disadvantageous.

The present invention has been made in view of such a conventional situation. In a station service remote monitoring system, the number of cameras to be operated at the time of alarm display is reduced without increasing the number of cameras, and the work burden is reduced. And to improve the overall work efficiency.

[0007]

In order to achieve the above object, the present invention uses a camera capable of automatically turning at a designated position, and controls the camera operation of the turning camera by controlling station equipment, intercoms and the like. This is to automate the camera operation in conjunction with the alarm from the target device. For example, the present invention
When the alarm signal is transmitted from the device to be controlled to an operating device equipped with a computer such as a control PC (personal computer), the control by the operating device selects a turning camera around the device based on the alarm signal, and The main purpose is to turn the turning camera so as to face the vicinity of the target device, shoot under predetermined shooting conditions such as zoom and focus, receive the image obtained from the turning camera, and display it on the monitor. .

Thus, the manual operation by the operator is omitted, and the work load can be greatly reduced. In addition, by automatically performing camera control based on an alarm from a device to be controlled, it is possible to monitor an image of a place where an abnormality has occurred without any operation. At this time, since the camera turns, for example, to a preset position, it is possible to accurately photograph the periphery of the abnormal device.

The present invention has been completed based on such an idea.

[0010] That is, an event-linked station service monitoring system using a turning camera according to the present invention detects a turning camera for photographing a monitoring target peculiar to a railway, and detects a specific event to be monitored from the monitoring target. In conjunction with the detecting means and a specific event detected by the detecting means,
