Field of the Invention The present invention relates to disaster prevention monitoring provided with various detectors such as gas leak detectors and fire detectors, disaster prevention equipment such as fire doors and smoke exhaust devices, and various terminal equipment such as receivers. Concerning the system, in particular, the situation of the monitored area is graphically displayed on the monitoring display device installed in the central monitoring room, etc., and the operation and control contents of these terminal devices are also displayed to centrally perform disaster prevention monitoring. The present invention relates to a monitoring and displaying method of a disaster prevention monitoring system.

[0002]

2. Description of the Related Art Conventionally, in such a disaster prevention monitoring system, a display of a central control panel installed in a central monitoring room, etc., displays a plan view of a monitoring area and installation locations and types of various terminal devices. It becomes possible to perform centralized monitoring by superimposing an identification code or the like for identification, and when an abnormality is detected by the terminal device, displaying the information on the display screen of the display device by character information or the like. Was there.

Further, when the identification code on the screen is designated by a pointing input device such as a so-called mouse or light pen, the fire detector or the gas leak detector corresponding to the identification code is caused to measure the current situation, and It had a function of displaying the measurement result on the screen and controlling such as activating a disaster prevention device such as a fire door corresponding to the identification code. Then, in order for the monitor to easily perform the control operation and the command operation of the measurement for such a terminal device, the operation item to be selected is displayed on an appropriate portion of the screen, and the monitor displays the operation item. When one of the items is specified by the pointing input device, the terminal device is instructed to perform the process corresponding to the item, and the measurement and control are performed.

More specifically, when an identification code on the screen is designated by the pointing input device, in the case of a sensor, a display area having items such as "measurement" and "cancel" (hereinafter referred to as window display) Area), and in the case of a disaster prevention device, a window display area having items such as “start”, “return”, and “cancel” is set. Then, when the item of "measurement" is further designated by the pointing input device, the sensor corresponding to the identification code measures the current situation,
The measurement result is displayed near the identification code. If "Cancel" is specified, the measurement operation is terminated and the window display is erased. On the other hand, "startup" related to disaster prevention equipment
When the item of is specified with the pointing input device, the command corresponding to the identification code, for example, the shielding operation of the fire door,
When the item of is specified, the opening operation of the fire door corresponding to the identification code is instructed. In addition, the window display for specifying the "cancel" item related to the disaster prevention device disappears.

As described above, by displaying the command item of the terminal device designated by the pointing input device in the window and further designating the item from the command item, the observer can perform desired measurement and control without making a mistake. It was like this.

[0006]

However, in the conventional monitoring display method of the disaster prevention monitoring system as described above,
The window display only displays items for unilaterally commanding each terminal device, so whether each terminal device is actually operating in response to that command, and what kind of operation The observer could not confirm if there was a situation. For this reason, taking the fire door as an example, whether the fire door is actually performing the shielding operation according to the designation of the item of “start”, but the surveillance person is actually performing the shielding operation. It is not possible to check the reliability, and repeat meaningless operations such as specifying the same item over and over again, or it may be necessary to actually go to the installation location to check the operation of the fire door. The operability was a problem. Also, the same problem has existed in the case of commands to other terminal devices.

The present invention has been made in view of the above problems of the conventional monitoring and displaying method, and an object thereof is to provide a monitoring and displaying method of a disaster prevention monitoring system capable of confirming the operation and the like of each terminal device. To do.

[0008]

SUMMARY OF THE INVENTION In order to achieve such an object, the present invention is such that when information of a terminal device displayed on a screen of a display device is designated by a command input device such as a light pen, the terminal device is displayed. When an item for specifying an operation for a device is displayed in a window, and if any item in the window display is specified, the operation corresponding to the specified item is instructed to the terminal device and the operation status of the terminal device is displayed in a window. I decided to do it.

[0009]
