Description

  The present invention relates to a gas safety training system that supports training of security personnel through reproduction of a simulated gas accident.

  As a type of training system that performs training through dialogue with a monitor screen using computer simulation, Patent Document 1 describes a security work training system that executes training related to security work procedures for a user by computer processing. ing. In this system, the user of the training system can simulate the security work site by using the on-site screen displayed in the on-screen screen display area by the on-site screen display unit, and display the on-site screen according to the intention of the trainee user. By moving the security work site while changing the area and selecting the work location displayed on the site screen, the individual work in the series of security work scheduled in the training scenario can be performed according to the intention of the user. Each can be performed in the order selected. Also, the work content evaluation unit is executed in the order specified by the work content input by accepting and recording the work content input executed separately in the order selected by the user's intention. The work contents of each individual work can be evaluated by comparing with the contents of each individual work in the training scenario. However, in the training through the monitor screen, since the body is not moved, the sense of reality is insufficient, and a training result such as learning with the body cannot be obtained. This is especially a problem for disaster prevention drills for gas leaks and fires that actually require quick and calm action under great tension.

  In gas safety training, there are limitations on the monitor, but there are advantages in computer simulation that can learn how to deal with various accidents by reproducing various accidents, and there are limitations under certain conditions There is a need for an effective gas safety training system that harmonizes the benefits of attending an actual accident scene that can provide action for a particular accident.

  The gas safety training system according to the present invention is characterized by a simulated space in which remotely controlled gas equipment is installed, a training control database storing a plurality of training control patterns for reproducing an assumed gas accident in the simulated space, and A control device for controlling the gas equipment based on a training control pattern extracted from the training control database, and a behavior of a trainer for coping with a gas accident reproduced in the simulated space based on a predetermined training control pattern A training record database for recording information and a monitoring device for remotely monitoring the behavior of the trainee are provided.

  According to this configuration, an actual trainer can act, create a real simulation space that simulates a space where gas facilities such as residences and stores are installed, and install remotely-controllable gas facilities in it . The gas equipment can be remotely controlled by a control device, and its training control pattern is set to reproduce an assumed gas accident, and a plurality of training control patterns are stored in the training control database. Thereby, the trainee can experience an environment that reproduces an arbitrary gas accident in the simulated space, and can experience and learn the treatment that must be performed in the gas accident. Further, the treatment action of the trainer in the reproduced gas accident is computerized and recorded in the training record database, and the behavior of the trainer is remotely monitored by the monitoring device. Thereby, for example, in a command room located away from the simulated space, the trainee can be evaluated in real time and after the end of training. As long as the training control pattern is prepared, not only accidents that have actually occurred, but also accidents that can occur can be simulated, and all of them can be experienced while using actual body movements. can get.

  In order to realize a gas accident in the simulated space with a sense of presence, it is necessary to generate various events such as the occurrence of gas leaks with an accurate time passage. In addition, since it is training, when reproducing such a gas accident, it is necessary to advance or delay the actual event occurrence time. In order to satisfy such a demand and perform more effective training, in one of the preferred embodiments of the present invention, the training control pattern is executed in time series for the component devices constituting the gas equipment. The control command is included, the execution time of the control command can be changed, and a gas accident is reproduced by a plurality of control commands executed in time series.

  An important event in a gas accident, that is, an event that must be emphasized in gas safety training is the generation of gas and the distribution of the generated gas pool. Therefore, in order to simulate such a situation in the simulated space, it is necessary to discharge gas in a timely and appropriate amount freely from the gas pipes extending in the simulated space. For this reason, in one of the preferred embodiments of the present invention, the element device includes a remote control valve that discharges gas from a gas pipe disposed in the simulation space to the simulation space. This creates an optimal gas pool distribution and provides effective training.

  As one simple but effective form of the gas safety training system according to the present invention, the treatment information is a television camera image of the behavior of the trainee, and the training record database stores a recording file of the television camera image. It is proposed to configure. According to this system, the state of a trainer who is performing training in a simulated space in which various gas accidents are reproduced is photographed with a television camera, and the television camera image is recorded and stored in a training record database. Thereby, the state of specific training can be confirmed and learned through the monitor screen at any time, and the training effect is further enhanced. In addition, a recording system that records and stores a television camera image that captures the state of training can be constructed at a relatively low cost, which is advantageous in terms of cost.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram showing an outline of a gas safety training system according to the present invention. The simulated space 10 here is formed as stores and residences arranged on a plurality of floors of the training facility building, and the arrangement of the stores and residences on the specific floor is shown in FIG. The store area 11 and the residential area 12 are provided with gas pipes 2 and 3, and each branch pipe of the gas pipes 2 and 3 is provided with an opening / closing valve. In this embodiment, as a branch pipe of the gas pipe 2, an open branch pipe 21 whose end is opened, and as a branch pipe of the gas pipe 3, a terminal device 23 such as a gas stove or a water heater is connected to the end. Equipment branch pipes 31 are provided. The end opening of the open branch pipe 21 is arranged at a place where gas is likely to stay in a gas leakage accident in the surrounding area, and the accident is simulated by releasing a predetermined amount of gas from the end opening. The required gas can stay in place. Some of the open branch pipes 21 are provided with only a solenoid valve as the on-off valve 22, and some are provided with a gas meter and a meter gas plug 25 that can be manually operated in addition to the on-off valve 22. Although the gas supplied to the gas pipe 2 is harmless, the odor is similar to a real gas. Further, 13 A gas is supplied to the gas pipe 3, and an electromagnetic valve and a terminal device 23 are connected as an on-off valve 32 in the vicinity of the terminal end. The provision of the equipment branch pipe 31 to which 13A gas is supplied in this way is advantageous in order to more accurately reproduce the actual gas piping state in a store or a residence. The equipment branch pipe 31 and the terminal equipment 23 can be used for performing an ignition test after eliminating the gas leakage in the gas safety training.

  An example of a gas that is harmless to the gas pipe 2 and has an odor similar to a real gas is obtained by diluting the 13A gas to a sufficient 1 and adding the odorant to the odor of the 13A gas. It is added to the extent. As such a gas component, 35% helium, 55% nitrogen, and 10% 13A gas are preferable, and an appropriate odorant is added thereto. When performing gas leak training with such a gas, it is advantageous to increase the detection sensitivity of the gas detector for the 13A gas used by 10 times because the detection performance is the same as for the 13A gas. .

  With such a gas pipe, each simulated space 10 can faithfully reproduce a gas leak accident, a gas accumulation accident due to a gas leak from a pipe crack, and the like. In addition, an operation detection sensor 24 that can detect the operation status of the operation knobs and meter gas plugs of each terminal device 23 is also connected, and the trainer correctly sets the operation knobs and meter gas plugs 25 and the like for safety. It is configured so that it can be checked remotely whether it is operating. In the present invention, the gas pipes 2 and 3, the branch pipes 21 and 31, the on-off valves 22, 25 and 32, and the terminal equipment 23 are collectively expressed as gas equipment, and at least as the on-off valves 22 and 32. The solenoid valve can be remotely controlled. Further, the meter gas stopper 25 and the solenoid valve as the on-off valve 32 in the same store area 11 and the same residence 12 can be interlocked. When the trainer opens the meter gas stopper 25, the gas stove end device 23 The on-off valve 32 is opened in conjunction with the ignition test so that the ignition test can be performed smoothly.

  The gas safety training control device 5 which is a core element of control in the gas safety training system is installed in a training command room assigned to one corner of the same training facility building. In the simulated space 10, a television camera 81 and a speaker 82 connected to the gas safety training control device 5 are arranged. The instructor standing by in the training command room can monitor the behavior of the trainee while viewing the captured image acquired by the TV camera 81, and can give a voice instruction to the trainer through the speaker 82 as necessary. it can. The television camera 81 and the monitor 84 that displays the captured image function as a monitoring device that remotely monitors the behavior of the trainee.

  In actual training, the control content described in the training control pattern applied for training is read, and the time series for controlling the solenoid valves 22, 32, the terminal device 23, and the alarm device in accordance with the control content. Control commands that are automatically deployed are generated and output in a timely manner. An event occurs according to a gas accident scenario according to the applied training control pattern, and the content of the treatment performed by the trainer for the generated event is converted into treatment information (electronic medical chart) in the gas safety training control device 5, Stored as training records.

  There are many training control patterns that can be applied to training, and accident scenarios are different. However, in training, there are many cases in which some scenarios are desired to be changed according to the skill level of the trainee. For this reason, the manual control command function which changes a part of training control pattern prepared beforehand and outputs a control command based on the changed training control pattern is also provided. In changing the training control pattern, it is advantageous if the scenario is changed based on the past treatment information of the trainee so that the training becomes more effective. Also, through this manual control command function, it is possible to change the scenario (increase / decrease in gas leak location, etc.) in real time according to the training state of the trainer even during training. As a result, it is possible to implement training that matches the proficiency level of the trainee.

  Next, an example of a gas safety training control apparatus constituting the gas safety training system of the present invention will be described using the functional block diagram shown in FIG. This control device is substantially a computer connected to an external input / output device such as a TV camera 81, a speaker 82, a microphone 83, a monitor 84, a keyboard 85, a mouse 86, etc. The functions shown in FIG. These various functions are realized by software and / or hardware.

Here, as the monitor 84, a training status confirmation monitor 84a for displaying an image captured by the television camera 81 and a control operation monitor 84b for setting a training control pattern and the like are provided. This control operation monitor 84b can also display the alarm alarm and the opening / closing of each solenoid valve and gas plug. Of course, by switching the screen on the same monitor, it can also be used as the training status confirmation monitor 84a or the control operation monitor 84b. The control operation monitor 84b may also be configured to display an image captured by the television camera 81. In the example of FIG. 3, the control operation monitor 84 b is connected to the gas equipment control unit 50 and the treatment information generation unit 71, but it may be connected to either one or to other functional element units.

  FIG. 5 illustrates the time series information of a specific training control pattern as a display form on an editing screen for editing this time series information. From FIG. 5, the time-series information includes the opening time and closing time of each electromagnetic valve 22 to be controlled in accordance with the scenario. Therefore, by setting and inputting the opening time and closing time of each solenoid valve 22 so as to match the scenario, each solenoid valve 22 is controlled in time series according to the scenario, and a desired gas accident is created in a simulated manner. It is. Further, the alarm time can be set so that the gas leak alarm can be included in the contents of the scenario. The edit screen of FIG. 5 is configured to be used for the purpose of confirming the details of the gas accident during training. For example, in order to check the operation details required by the trainer, this training control pattern , A check column for the operated meter gas plug 25 is also provided.

  In this embodiment, the training record database 62, which is another database constructed in the recording unit 6, converts the treatment information resulting from the gas safety training conducted at this facility into the trainer and the training control pattern. It is stored separately. The treatment information includes the degree of achievement of operations and behaviors required by the trainee, video images taken during the training, and the like. This treatment information is created through the treatment information generation unit 71 and stored in the training record database 62. The treatment information generation unit 71 is input with video image information obtained by photographing the training situation processed by the video processing unit 72, instruction contents during training performed by voice, and training evaluation information created by an instructor. . The video processing unit 72 has a function of distributing video image information sent from a plurality of television cameras 81 to the monitor 84 and the treatment information generating unit 71, and if necessary, a video format (screen size, etc.). Although a conversion function can be added, it may be configured simply as a video selector. Alternatively, the video processing unit 72 may be omitted by incorporating a function required for the video processing unit 72 into the treatment information generation unit 71. In this embodiment, the monitor 84 for training status confirmation and the monitor 84b for control operation are provided as the monitor 84. However, the monitor 84b for training status confirmation is omitted and the monitor 84b for control operation is confirmed for training status. It may be configured to display real-time video image information or recorded video image information by the television camera 81 on the control operation monitor 84b so that it can also be used as a monitor. The video image information includes not only the video image but also the shooting date and time and the shooting location.

  The gas equipment control unit 50 controls the opening and closing of a large number of solenoid valves 22 provided in the gas pipe 2 installed in the simulated space constructed in the form of a store or a residence in time series via the gas equipment control driver 80. Thus, a simulated gas accident according to a predetermined scenario is created. The gas equipment control unit 50 includes a control command generation unit 51, a scenario evaluation unit 52, a time series processing unit 53, and a training information evaluation unit 54. The scenario evaluation unit 52 extracts the training control pattern stored in the training control database 61, and reads out the control content for reproducing the specific gas accident included in the training control pattern, that is, the gas accident scenario. . The contents included in the extracted training control pattern are displayed on the monitor 84 as illustrated in FIGS. At least a part of the displayed contents can be added or modified by an operation input using the keyboard 85 or the mouse 86 through the manual control command unit 70.

  The time series processing unit 53 processes time series information included in the extracted training control pattern, that is, a timeline, and calculates an operation timing based on, for example, a training start point of the opening / closing operation of each electromagnetic valve 22. The training information evaluation unit 54 is an additional function. If the past training information of the trainer who performs this gas safety training is stored in the training record database 62, the training information is evaluated and adopted this time. Encourage corrections and additions to the training control pattern. Moreover, you may comprise so that it may operate | move as a support function for determining the training control pattern implemented this time based on such past training information.

  The control command generation unit 51 receives the opening / closing control information such as the electromagnetic valve 22 from the scenario evaluation unit 52, and the calculated operation timing from the time series processing unit 53, generates a control command (control signal), and generates the gas in a timely manner. Output to the equipment control driver 80. In addition, if there is past training information of the trainee evaluated by the training information evaluation unit 54, an instructor refers to this through the manual control command unit 70, and shows a training control pattern, that is, a training scenario as shown in FIG. It also has a function of editing through a graphic interface. The manual control command unit 70 also has a function of creating a new training control pattern by an instructor. In other words, it also functions as a training control pattern input unit that allows the instructor to input a new training control pattern.

  In the gas safety training system configured as described above, when a gas safety training based on a predetermined training control pattern (a predetermined gas accident scenario) is started, a gas leak notification is performed through a simulated report or a gas leak alarm device. At the same time, the trainee heads to a residence or a store as the simulated space 10 that is the subject of the security training. The electromagnetic valve 22 mounted on the gas pipe 2 installed in the simulated space 10 is operated, and a gas leak according to the scenario is caused. Based on the gas safety manual, the trainer will sequentially detect and deal with dangerous gas leaks, close open switches such as meter gas plugs and service valves, and remove or block stagnant gas. The pattern is monitored by the instructor in the training command room, and voice instructions are given as necessary. The training result is computerized and recorded in the training record database 62.

  Even during the training, if it is determined that the instructor monitoring the training situation should correct the training control pattern being executed, the training control pattern correction function by the manual control command unit 70 is used for training. It is also possible to change the accident scenario.

In addition, when sound in the training space can be acquired by the recording microphone 73a built in the TV camera 81 or provided individually, this sound is also incorporated into the TV camera image and processed. In this alternative embodiment, the video processing unit 72 is omitted, and a real-time video image or a recorded video image from the television camera 81 is recorded on the training status confirmation monitor 84a connected to the treatment information generation unit 71. Displayed through the processing unit 71. The video image information includes not only the video image but also the shooting date and time and the shooting location.
According to such a system, the state of a trainee who is performing training in a simulated space in which various gas accidents are reproduced is photographed by the television camera 81, and the television camera image is recorded and stored in the training record database. By doing so, the state of specific training can be confirmed and learned at any time through the monitor screen.
(5) In the embodiment described above, the treatment information generation unit 71 is provided separately from the training record database 62, but the server that is the training record database 62 may have the function.
