BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disaster prevention training simulator that allows a trainee to perform a predetermined procedure on the assumption that an abnormal situation occurs in a factory or the like.

[0002]

2. Description of the Related Art When a fire occurs in a liquefied gas plant facility or the like, initial fire extinguishing activities including quick security measures are important in order to avoid secondary disasters caused by the fire as much as possible. Conventionally,
These fire drills are implemented as evacuation drills, drainage drills, and some small-scale fire drills. In particular, for security measures, since the actual operation of the valve is not possible, check the valve position on the drawing on the desk and go straight to the valve position on site,
It was only a simulated operation.

In addition to gathering and evacuation guidance, actual fire extinguishing drills for small fires were conducted, and it was not possible to conduct fire drills combining fire extinguishing training with the operation of operation adjustment line blocks for equipment security.

In order to cope with such an abnormal situation, there is a simulator that generates an abnormal situation on a computer and trains a trainee. However, such a simulator generates a secondary disaster or the like during operation of a factory. Not taken into account.

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a block diagram showing a schematic configuration of the disaster prevention training simulator 1. The disaster prevention training simulator 1 includes a control computer 3, a simulator body 5, a disaster prevention training simulator 7, and a field simulator 9.

The control computer 3 has a DCS (Dis
tributed Computer System)
And sends a control output (analog output AO or digital output DO) to the simulator body 5.

The simulator body 5 displays various facilities, equipment, piping, valves, etc. in the factory. Here, for example, a factory that handles LNG, naphtha, LPG, and the like is targeted. The simulator body 5 generates a malfunction (abnormal situation), simulates outflow of LNG, naphtha, LPG, etc., calculates state quantities such as pipe pressure, outflow flow rate, and outflow temperature, and sends them to the disaster drill simulator 7. These in-pipe pressure and outflow flow rate are calculated, for example, about once a second. The simulator body 5 sends the state quantities and limit values to the control computer 3 as analog inputs AI and digital inputs DI.

The disaster prevention simulation simulator 7 performs a jet diffusion calculation of a fluid (for example, LNG), a fluid heat conduction calculation, an ignition damage calculation, a heat radiation calculation, and the like, and calculates an outflow range and a thermal influence range of the fluid.

In the jet diffusion calculation, for example, the outflow state of a fluid such as LNG from a broken portion of a pipe is calculated. The fluid heat conduction calculation calculates a change in the surface temperature of the surrounding piping equipment. The ignition and fire calculation calculates the shape of the flame. The calculation by the disaster prevention simulation simulator 7 is performed, for example, about once every two to three minutes.

The field simulator 9 determines an affected device based on the calculation output of the disaster prevention simulation simulator 7 and expresses the outflow state of a flame or a fluid using computer graphics (CG), virtual reality (VR), or the like. .

Next, the operation of this embodiment will be described. A control output is sent from the control computer 3 to the simulator body 5. Generate a malfunction (abnormal situation) in the simulator body 5 (step 1)
1). For example, a fluid such as LNG, naphtha, or LPG is simulated to flow out, and state quantities such as a pipe pressure, an outflow flow rate, and an outflow temperature are calculated.

The disaster prevention simulation simulator 7 uses the fluid (for example, LN) based on the pipe pressure, the outflow flow rate, the outflow temperature, and the like.
G) jet diffusion calculation, fluid heat conduction calculation, ignition and damage calculation,
A heat radiation calculation is performed (step 15). Then, the outflow range and the thermal influence range of the fluid are calculated by these calculations (step 17).

The field simulator 9 determines an affected device according to the calculation result of the disaster prevention simulation simulator 7 and displays the outflow state of the flame or the fluid using a computer graphic or the like (step 19).

FIG. 2 is a diagram showing display contents displayed on the screen of the field simulator 9. Reference numeral 31 denotes a certain section in the factory. 33 is a tube, 35 is a device, 37 is a surface temperature upper limit region, and 39 is a flame existing region. The surface temperature upper limit region 37 is a region in which the temperature exceeds the upper limit of the temperature required for maintaining the device and the like.

As shown in FIG. 2, the device 35a is in the flame existence region 39, and the devices 35b and 35c are in the surface temperature upper limit region 37. The trainee looks at such a screen and determines the operation mode of the affected device in the simulator body 5 (step 13). For example, the simulator body 5
On the screen showing the facilities in the factory displayed above, operations such as closing a predetermined valve are performed. In addition, a simulator for on-site training previously filed by the present applicant (JP-A-7-160)
No. 188) is used to close a valve of a simulated on-site facility.

As described above, when the trainee performs a predetermined operation, the simulator main body 5 again calculates the pipe outflow flow rate, the outflow temperature, etc. in accordance with the operation, and sends it to the disaster prevention simulation simulator 7. Then, the above processing is repeated.

As described above, in the present embodiment, in the factory operation training at an LNG factory, a petroleum refining plant, and the like, in the event of a disaster or secondary disaster, the security treatment training is performed in real time in the same manner as the actual situation. You can experience with a high sense of presence,
Advanced learning in response to disasters.

[0020]

As described above in detail, according to the present invention, a disaster or a secondary disaster is assumed to occur in a factory or the like, and the security processing training can be performed in real time with a high sense of realism. Learning can be performed.
