Information storage device 4 and information storage device 4
The measured values of the outputs of the various sensors 3 stored in the memory are read, and the changes over time of the outputs of the various sensors 3 are monitored as operating state monitoring information. When abnormal changes over time are indicated, the possibility of a disaster occurring is predicted.

Power plant 2 And a display device 11 for displaying the respective area 10.

The thermal power plant 2 has a turbine generator 15 at the center.
A fuel tank 16 in which oil, which is a fuel for driving and controlling the turbine generator 15, is installed, and a chimney 1 for exhausting smoke through a boiler.
7. Monitor the operating status of the switchyard 18 and the turbine generator 15 where a circuit breaker for transmitting and distributing the electric power generated by the turbine generator 15 is installed to cut off the circuit at the time of leakage or short circuit of the transmission / distribution line, An office 19, a guard station 20 and the like, in which a control console that constitutes the generator control device 14 for controlling is installed, are installed. Furthermore, a passage 21 for automobiles and humans that passes between these equipment positions is laid inside the thermal power plant 2, and the evacuation center 2 is located in a safe place where the thermal power plant staff can evacuate in the event of a disaster.
2 is set, and the area 10 is provided in this evacuation center 22 as a unit of guidance for the staff to evacuate. The thermal power plant 2 is installed in this way.

The thermal power plant 2 is provided with various sensors 3 for outputting operating condition monitoring information in order to predict a disaster. The operating state monitoring information of the thermal power plant 2 is, for example, information monitored by the control console of the power generation control device 14 installed in the office 19. The operating status monitoring information is
The information output by the various sensors 3 installed in the power generation equipment is used as physical and chemical measurement items such as generated power, transmission current, transmission voltage, turbine speed, turbine temperature, power generation frequency, generator speed, and power generation. Measured values include machine temperature, fuel tank pressure, fuel tank temperature, and fuel consumption. The operating state monitoring information is continuously or intermittently stored in the information storage device 4 in association with each measurement date information. If the monitoring information of the control console is sufficient, the monitoring information of the control console is used as the operating status monitoring information.
The operating state monitoring information is a measurement item for predicting the occurrence of a disaster, and may be one item as long as it is an effective item for predicting or causing a disaster.

The various sensors 3 are, for example, pressure, temperature, time,
It is a sensor that measures each item such as humidity, flow rate, flow velocity, viscosity, voltage, current, and electric power, converts it into an electric signal, and outputs it. With regard to pressure, flow rate, flow velocity, and viscosity, a piezoelectric sensor outputs a pressure value as an electric signal. As for the temperature, a thermistor outputs a change in temperature as a change in electricity. Humidity is measured by a humidity sensor.

The entrance / exit of each staff member is monitored at each entrance / exit of each area 10, and whether there is a staff member (human being) in each area 10 at present is checked.
An entrance / exit monitoring sensor 25 for determining whether or not there is installed. That is, in a certain area 10, for example, if there are 5 residents and 3 sources,
It outputs when there are residents, and outputs that the number is 2. The output of the entrance / exit monitoring sensor 25 in each area 10 is supplied to the person presence / absence determining unit 27 via each area entrance / exit monitoring device 26, and the person information storage device 28 monitors the presence / absence information of the person in each area 10. The date and time information is stored in association with the area name and the like.

An enlarged view of the relationship between the various sensors 3 in each area 10 and the entrance / exit monitoring sensor 25 is shown in FIG. 2 for the sake of clarity. In FIG. 2, the monitoring device 29, for example I
One or a plurality of TV cameras are installed so that each area 10 can be monitored. The monitoring device 29 images and outputs the states of the devices and humans (members) 30 existing in the area 10. When a fire occurs from the device, an image of the fire is output, and if the person 30 has started evacuation, an image of the evacuation state is output. Therefore, the monitoring device 29 outputs an image of the current position of a person who is injured and cannot move, or a person who is physically disabled and cannot move. It is extremely effective for rescue to know the place where there is a person who cannot move like this. The output of each monitoring device 29 provided in each area 10 is stored in the information storage device 4 via the area monitoring data collection device 23 in association with the date information and the area information.

Next, the disaster prediction will be described. The disaster prediction calculation unit 5 includes various sensors 3 stored in the information storage device 4.
The measured value of the output is read continuously or intermittently (predetermined period), and the time-dependent change of the outputs of the various sensors 3 is monitored as operating state monitoring information. When an abnormal time-dependent change is indicated, it is stored in advance. Comparing the change value of the disaster occurrence with A
I logical operation is performed to predict the possibility of disaster occurrence. The abnormal change over time refers to a change with a large gradient different from the change over time under normal operating conditions.

The disaster prediction calculation unit 5 has a configuration as shown in FIG. 3 to monitor the operating condition and output a disaster prediction when an abnormality is detected. Next, a specific example of monitoring the operating condition and predicting a disaster will be described with reference to FIG. The safe normal operation state (condition) of each device and each device is stored in advance in the generator operation normal operation range data table 35. The measurement values 36 of the various sensors 3 stored in the information storage device 4 are read out and sequentially compared with the normal operation operation values stored in the generator operation normal operation range data table 35 by the comparison circuit 37 and predetermined. It is a normal state if the measured value of the obtained normal operation state.

On the other hand, when the collation circuit 37 shows a change different from the normal state as a result of the collation, the abnormality detecting section 38 detects the presence or absence of an abnormal change over time. The abnormality detecting unit 38 determines that there is an abnormality when it detects that there is a change with time, and outputs it. Further, the abnormality detecting unit 38 outputs an output which is regarded as normal operation when detecting no change with time. When the abnormality detection unit 38 outputs an abnormality (when the measured value shows a change over time), a disaster /
The failure determination unit 39 determines whether it is a “failure” or a “disaster occurrence” as follows.

In order to determine whether it is a "fault" or a "disaster occurrence", the disaster occurrence threshold data table 40 shows the change over time obtained by various experiments for each measurement item of each device and each device. The threshold value at which a disaster occurs is stored. The disaster / fault determination unit 39 reads the threshold value of the measurement item determined to be abnormal from the disaster occurrence threshold data table 40, and collates it by the collation circuit 41. Changes over time are processed using, for example, gradient value information. That is, as a result of the collation, if the gradient value of the item for which the abnormal value is measured outputs the threshold value 42 or more read from the disaster occurrence threshold data table 40 as a result of the collation, the collation circuit 41 determines that it is a dangerous change value, and there is a possibility of disaster occurrence. Output the judgment.

On the other hand, as a result of the collation, the collation circuit 41 outputs a failure value 45 when the gradient value of the item for which the abnormal value is measured outputs a value 44 or less than the threshold value read from the disaster occurrence threshold data table 40.
The judgment of is output.

As a result of the determination of the failure 45, the operation of the thermal power plant 2 is stopped 46, the repair 47 is performed, and the process ends. The abnormality 45 that may cause a disaster is determined from a characteristic curve diagram as shown in FIG. 4, for example. For example, it is determined by a graph in which the horizontal axis is the time axis and the vertical axis is the turbine temperature.

In this graph, the change in the normal operating temperature N is shown by a solid line. The solid line N indicating normal operation indicates the operating temperature when the temperature of the turbine rises from room temperature to the preset temperature during steady operation after switching on and reaches a preset temperature during steady operation, and shows steady saturation characteristics while performing steady operation. continue. In this graph, the alternate long and short dash line indicates the maximum normal operating temperature M of the turbine.

At some point, when the temperature measurement value of the temperature detection sensor 3 starts to rise as indicated by the dotted line G and it is determined that the temperature is rising at a speed exceeding the maximum normal operating temperature M, it is determined that a disaster will occur. To do. The determination that the temperature rises at a speed exceeding the normal operation maximum temperature M and that a disaster may occur is inferred from the angle (gradient) indicated by the dotted line G, that is, the change over time. The angle (gradient) indicated by the dotted line G, that is, the time-dependent change value, is stored as a threshold value for disaster occurrence (for example, fire occurrence) by previously collecting various types of experimental data for each measurement item of each device. The angle indicated by the dotted line G, that is, the time-dependent change value is stored in the disaster occurrence threshold data table 40 in association with each device and model name.

The angle (change over time) indicated by the dotted line G is compared with the disaster occurrence threshold data of the device stored in the disaster occurrence threshold data table 51 by the matching circuit 52. It judges that there is a possibility and outputs the disaster occurrence prediction. If it is less than or equal to the disaster occurrence threshold, it is judged to be a failure, power generation of the thermal power plant 2 is stopped, and repair is performed. These outputs are stored in the information storage device 4 in association with the device name.

A point G1 on the dotted line G indicates the time when the measured value for outputting the disaster occurrence prediction information is obtained. An extension line G2 from the point G1 is a prediction line obtained by the AI logic operation. The time S at the intersection of the predicted line G2 and the maximum normal operating temperature M of the turbine is a guideline for the predicted occurrence time information of the disaster. In this way, the disaster prediction information output device 6 outputs the disaster occurrence prediction information in advance. The disaster occurrence prediction information is the disaster occurrence prediction location information and the disaster content information from the sensor that measured the abnormality,
Then, from the graph shown in FIG. 4, there are information such as predicted disaster occurrence time information. The disaster content information of this embodiment is, for example, a disaster such as a fire or an explosion, which is predicted from the mounting device of the measurement sensor, the device, and the measurement item when the occurrence of the disaster is predicted from the change in the measured value over time, and its scale. It is information such as.

Next, the notification of the disaster prediction will be described.
When the disaster prediction information device 6 reads the prediction information of the possibility of occurrence of a disaster in the turbine generator from the information storage device 4,
It is displayed on the personal computer 55 and the disaster prevention board 56, and at the same time, it is reported to the government office 58 such as a police station or a fire station through the disaster prevention center 57. Furthermore, the disaster prediction information device 6 outputs it to the optimum evacuation guidance route map selection unit 8 which selects the optimal evacuation guidance route map for each area.

In the selection section 8 of the optimum evacuation guidance route map, the staff 30 in the area 10 where a disaster is predicted to occur is in the evacuation center 2
Search the evacuation guidance route map that shows the optimal guide map for evacuation to 2. For the passages inside the building and the roads on the premises that are optimal for evacuating to the shelter 22, a safe evacuation route without dangerous gas leaks or roads under construction is automatically searched as selection conditions (selection ) Will be done. Also, the staff member 30 can operate his / her own personal computer 55 to directly access the selection section 8 of the optimum evacuation guidance route map and select an evacuation route depending on the situation. The optimal evacuation guidance route map selection unit 8 is an evacuation guidance route device 7 that stores and stores a large number of evacuation guidance route maps.
The evacuation guidance route map pattern is sequentially read out from, and the optimum evacuation guidance route map up to a predetermined shelter 22 is automatically searched and output. The optimal evacuation guidance route map is a diagram in which the direction of evacuation is described on a premises map, for example, so that it can be instantly judged without error even in a panic state. The optimum evacuation guidance route map information selected by the optimum evacuation guidance route map selection unit 8 is:
It is input to the evacuation guidance information notification device 9. The evacuation passages and roads to the shelter 22 are the latest information confirmed to be passable by a surveillance camera, an optical fiber sensor, or the like.

The evacuation guidance route storage device 7 stores a large number of evacuation guidance route maps which are considered in advance for evacuating from each area 10 in the thermal power plant 2 to the shelter 22 in association with each area 10. There is. That is, the evacuation guidance route storage device 7 stores a large number of evacuation guidance route maps from each area 10 to a predetermined shelter 22 in advance.
The evacuation guidance route covers all roads and passages in the building that appear on the map, and is a wide variety of routes leading to the shelter 22.

Since the prediction of the occurrence of a disaster occurs suddenly, the optimum evacuation guide route map is always different. Therefore, the optimum evacuation guide route map selector 8 selects the optimum evacuation guide route map at that time. Further, the optimum evacuation guidance route map can be selected by searching the evacuation guidance route storage device 7 from the area 10 where the staff (human) 30 in the thermal power plant 2 exists, and the staff 30 in all areas 10 can be selected. Can also select the optimum evacuation guidance route map at the same time. That is, when the disaster occurrence prediction information is output, the optimum evacuation guidance route map selection unit 8 outputs the optimum evacuation route map information after confirming whether a disaster has occurred in the area. In addition, the optimum evacuation guidance route map is selected from the areas without obstacles by checking the presence / absence information of obstacles imaged by the monitoring device 29 in each predetermined area 10.

The optimum evacuation guidance route map selection unit 8 outputs the optimum evacuation guidance route map of each area 10 to the evacuation guidance information notification device 9. The evacuation guidance information notification device 9 is a circuit group that drives each display device 11 provided in each area 10.
On each display device 11 of each area 10, an optimal guide evacuation route map for guiding the staff 30 who is the evacuation target to the shelter 22 is simultaneously displayed. Each display device 11 has an optical display means and an acoustic display means as guidance display.

The optical display means is, for example, an electronic display board or LE.
Examples include D-array display boards, plasma displays, and car navigation systems. The acoustic display means broadcasts, for example, to notify by a voice from a speaker. The optimum evacuation guidance route map information is also output to a pre-registered information terminal such as a personal computer or a mobile phone connected to an intranet or the Internet. The evacuation guidance information notification device 9 is provided with a drive circuit for driving these display means. Further, the optimum evacuation guidance route map information is provided for the purpose of diverting the disaster occurrence to areas other than the predicted area 10.

The human information storage device 28 stores information on whether the staff 30 is present in the area 10 where a disaster is predicted or in another area 10. The information of the area 30 in which the staff member 30 is present is output to the selection unit 8 of the optimum evacuation guidance route map, and the selection unit 8 of the optimum evacuation guidance route map obtains the information of the area 10 in which the person 30 is not present. Therefore, the optimum evacuation guidance route map selection unit 8 can preferentially retrieve the optimum evacuation guidance route map from the area 10 where the staff member 30 is present.

An evacuation person confirmation device 60 such as an ITV camera is installed in the evacuation center 22 so that the number of people who have evacuated can be investigated and the evacuation completion judgment section 61 can confirm the evacuation status of the evacuation target person. That is, the evacuation person confirmation device 60 monitors whether the evacuation target person (member) 30 has evacuated to the evacuation center 22. Further, the evacuation person confirmation device 60 provided in the evacuation center 22 monitors the evacuation status to the evacuation center 22 and causes the evacuation completion determination unit 61 to indicate “how many of the evacuation target people have evacuated”.
Outputs evacuation information such as "Evacuation completion for all evacuees." When the evacuation completion determination unit 61 confirms the evacuation completion, the evacuation completion information is stored in the human information storage device 28. The evacuation completion information stored in the human information storage device 28 in this manner is read by the evacuation status confirmation unit 62 and automatically output (reported) to the government office 58 such as a fire station or a police station. Government offices 58 such as fire stations and police stations can confirm the evacuation status of the evacuation target person after the disaster forecast is output.

Next, an evacuation guidance method at a thermal power plant will be described with reference to the flowchart of FIG. 1 to 4
The same parts as those described above are given the same reference numerals for description, and detailed description thereof is omitted. Create a database as a preparation process.

The disaster prevention center 57 is the evacuation guidance route storage device 7.
In addition, various evacuation guidance route maps from each area 10 to the shelter 22 are stored in association with each area 10. The disaster prevention center 57 inputs an evacuation route or path if there is a prohibited road / passage during construction under construction on the evacuation route, corrects the evacuation route map, and stores it (S
-1). The disaster prevention center 57 sets the normal operation range of each physical and chemical measurement item corresponding to the model name of each device and equipment constituting the thermal power plant 2 in the normal value data table 40, and stores it in association with each measurement item. (S-2). The disaster prevention center 57 displays the thermal power plant 2 in the disaster occurrence threshold data table 51.
A time-dependent change value of a physical or chemical measurement item of each device or device that constitutes the item is set and stored in association with each measurement item (S-3). In this way, the preparation process is completed.

Next, the operation of the evacuation guidance system is started. During the power generation of the thermal power plant 2, the various sensors 3 are the thermal power plant 2
Each physical and chemical measurement item of each device and equipment constituting the device is automatically monitored and measured (S-4), and the measured value is stored in the information storage device 4 as operating state monitoring information (S-
5). The disaster prediction calculation unit 5 automatically reads the measured values stored in the information storage device 4 continuously or intermittently, and automatically plots the measured values on a graph as shown in FIG. 4 for each measured item. , Confirm normal operation with solid line N.

This normal operation is confirmed by checking the normal value of each measurement item read from the normal value data table 40 with the collation circuit 4.
It is confirmed by collating in step 2 (S-6). In this process, the presence or absence of change over time as indicated by the dotted line G in FIG. 4 is detected and stored as disaster occurrence prediction information (S-
7). When there is no change with time, it is determined that the operation is normal and the power generation operation is continued (S-8). The disaster occurrence prediction information includes a device (equipment) name, an area name, a disaster occurrence estimated time, and the like, which are predicted to have a possibility of occurrence of a disaster by the sensor.

If there is a change with time, the abnormality detection unit 43
Outputs an abnormal operation (S-9). If there is this abnormality, the disaster / fault determination unit 44 determines whether it is a disaster or a fault (S-10). That is, the disaster / fault determination unit 44 reads the disaster occurrence threshold value of the measurement item showing the change over time from the disaster occurrence threshold data table 51, and if the change value over time exceeds the read disaster occurrence threshold value, it is dangerous. It is determined that the value is a change value, and the disaster occurrence prediction information is output assuming that a disaster may occur. On the other hand, if the time-dependent change value does not exceed the disaster occurrence threshold value, it is determined that a failure has occurred (S-1).
1).

When the disaster / fault determination unit 44 determines that the power source has failed, the power generation control device 14 stops 46 the power generation operation of the thermal power plant 2 and repairs 47 (S-12), and then restarts thermal power generation.

When the disaster / fault determination unit 44 determines that a disaster may occur, the disaster prediction information output unit 6 causes the selection unit 8 of the optimal evacuation guidance route map to indicate the name of the device that may cause a disaster and this device. The contents information of the disaster such as the name of the area where is installed is output (S-13). Further, the person information storage device 28 outputs the area 10 information in which the staff 30 is present to the selection unit 8 of the optimum evacuation guidance route map. The optimal evacuation guidance route map selection unit 8 searches for the optimal evacuation guidance route map for evacuating from each area 10 to the shelter 22, and the evacuation guidance information notification device 9
Output to.

That is, the selection section 8 of the optimum evacuation guidance route map displays the optimum evacuation guidance route map for the name of the device having a possibility of disaster and the staff 30 in the area 10 where this device is installed. When the storage device 7 is searched, the evacuation guidance route map optimal for evacuation from each of the other areas 10 to the shelter 22 is also retrieved from the evacuation guidance route map storage device 7 and output. Optimal evacuation guidance route map selection section 8 is staff 30
It is possible to preferentially output the optimal evacuation guidance route map to the area 10 where there is. When the optimal evacuation guidance route map selection unit 8 outputs the disaster occurrence prediction information, the monitoring device 29 confirms whether or not a disaster has occurred in the area, and then outputs the optimal evacuation route map information (S-14). The guide information notifying device 9 is provided in each area 10 for each display device 1.
The optimal evacuation guidance route map is displayed on each display device 11 via the drive circuit 1 (S-15). Evacuation guidance information notification device 9
