[Means for Solving the Problems]
The gist of the present invention for solving the above-described problem of the underground monitoring system includes a detection sensor disposed in a mine tunnel, and a monitoring server program that collects detection data from the detection sensor and sends the data to a database server and a client. A monitoring server, a database server that stores detection data from the detection sensor and stores setting data used in the system, a setting data registration / editing program that registers and edits the setting data, and the detection data is a setting value. And a client having a monitoring screen program that issues an alarm via an alarming means, when the setting data registration / editing program is activated, the monitoring server program updates the detection data. Against the database server For only do clients of the monitoring screen program is that it has not performed.
[0007]
After the operation of the setting data registration / editing program is completed, the detection data stored in the operation time zone of the setting data registration / editing program is sent from the database server to the monitoring screen program, and a blank portion of the detection data is supplemented. That is to say.
[0008]
The gist of solving the above-mentioned problem of the underground monitoring program according to the present invention is to transmit detection data of a detection sensor disposed in a mine tunnel from a small station to a master station by a transmission request from the master station and collect the detection data. In the underground monitoring program, the master station issues a transmission request to all of the plurality of substations, and the substation transmits the detection data to the master station after the transmission request according to a predetermined order of transmission of the detection data. That is to say.
[0009]
According to the underground monitoring system according to the present invention, for example, in the case where a detection sensor is newly installed or moved due to the extension of the tunnel, even if the setting data registration / editing program is started, there is no need to stop the monitoring screen program. , And the detection data is continuously stored. Then, after the operation of the setting data registration / editing program is completed, the detection data stored in the operation time zone of the setting data registration / editing program is sent from the database server to the monitoring screen program, and a blank portion of the detection data is deleted. It will be replenished and the continuity of the detection data will be maintained.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, an underground monitoring system 1 according to the present invention will be described with reference to the drawings. Note that, for easy understanding of the invention, portions corresponding to the conventional example are denoted by the same reference numerals as the conventional example.
[0011]
The configuration of the underground monitoring system 1 is used for a mine tunnel as an example. As shown in FIG. 1, a detection sensor 4 disposed at an appropriate interval in the mine, and the detection sensor 4 Server 2 having a monitoring server program 2a for collecting detection data and sending it to the database server 3 and the client 5, and a database for storing detection data from the detection sensor 4 and setting data used in the system A client 5 having a server 3, a setting data registration / editing program 23 for registering and editing the setting data, and a monitoring screen program 24 for issuing an alarm via an alarm device 6 as an alarming means when the detection data reaches a setting value. It is roughly constituted from.
[0012]
The setting data is used by the entire underground monitoring system 1 such as drawing data indicating the arrangement of the mine tunnel, symbol data necessary on the screen display, the arrangement data thereof, and monitoring item data.
[0013]
The monitoring server program 2a of the monitoring server 2 collects the detection data from each of the detection sensors 4 disposed in the tunnel and links the detection data to the monitoring screen program 24 of the client 5 so that the detection data can be immediately transferred and updated. Being programmed.
[0014]
Further, when the monitoring server program 2a activates the setting data registration / editing program 23, it disconnects the link between the detection data and the monitoring screen program 24, and stores the detection data in the measurement value log of the database server 3. The monitoring screen program 24 is programmed so as not to send detection data as described below.
[0015]
That is, as shown in FIG. 2 (A), the update of the detection data from the monitoring server program 2a to the monitoring screen program 24 is changed so as not to be performed until the editing work is completed, or the detection data is always updated. The value “0” is sent to the monitoring screen program 24 as substitute detection data, so that the system is not stopped and restarted.
[0016]
Therefore, in the setting data registration / editing program 23, a drawing which is a map for showing a route of a new tunnel by extension of the tunnel or the like, a position of a new / additional symbol associated with the map, or monitoring of addition / new construction, etc. Even during the editing of the item, the monitoring server program 2a is running, and the detection data is collected and sent to the measurement value log of the database server 3 for storage.
[0017]
Further, even when the registration / editing operation in the setting data registration / editing program 23 is in operation, the detection data from the existing detection sensors other than the newly-installed or moved-object detection sensor is used to determine the gas concentration value or the like in advance. When the set “threshold value” is exceeded, a predetermined warning is issued by the monitoring screen program 24 via the warning device 6.
[0018]
New setting data is stored in the database server 3 by the editing operation by the setting data registration / editing program 23. Then, on the client 5 side, the editing work end and the data update switching button are input from the keyboard, so that the monitoring screen information based on the new setting data is taken into the monitoring screen program 24 and the measured value of the database server 3 is measured. From the log, the detection data stored during the operation time period of the setting data registration / editing program is taken into the monitoring screen program 24 as a past value.
[0019]
Therefore, as shown in FIG. 3, the detection data during the setting / editing work of the setting data registration / editing program 23 is displayed on the monitor 7 as a display means, and a continuous data display is performed. In this way, the lack of the detection data is prevented.
[0020]
