Embodiments for Carrying Out the Invention

[0012] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited to the following embodiments.

[0013] The danger prediction training device 1 according to this embodiment is an electronic device used for a user to perform danger prediction training. Danger prediction training is training implemented to find danger factors such as dangers and harmful factors lurking during work or driving, and to enhance the ability to appropriately respond to such danger factors. In this embodiment, a device used when performing danger prediction training related to work at a power plant will be described as an example. FIG. 1 is a front view showing the danger prediction training device 1. FIG. 2 is a block diagram showing the configuration of the functional blocks of the danger prediction training device 1.

[0014] As shown in FIGS. 1 and 2, the danger prediction training device 1 includes a main body unit 20, a display unit 30, a power supply unit 40, an operation unit 50, a cord-like member 60, a processing unit 10, a storage unit 70, and a housing 80.

[0015] The main body unit 20 is the main body of the danger prediction training device 1 and has a portable size. The main body unit 20 of this embodiment is horizontally long and plate-shaped, and is shaped so that it is easy for the user to hold by hand.

[0016] The display unit 30 is constituted by a display arranged on one surface (hereinafter referred to as the front surface) 21 in the thickness direction of the main body unit 20. On the display unit 30, various images such as problems of danger prediction training are displayed based on a control signal from the processing unit 10.

[0017] The power supply unit 40 mainly includes a battery (not shown) and a plug-in terminal (not shown). The battery is, for example, a button battery. The battery of this embodiment is a secondary battery such as a lithium-ion battery and is built into the main body unit 20. The plug-in terminal is provided on the side surface of the main body unit 20 and is a terminal into which a charging USB cable for charging the battery can be plugged. Note that a cover portion (not shown) for covering the battery is provided on the other surface (not shown) in the thickness direction of the main body unit 20. By opening the cover portion, the battery can be removed from the main body unit 20.

[0018] The operation unit 50 is arranged on the front surface 21 of the main body unit 20 and includes a power switch 51, a theme selection switch 52, and a re-selection switch 53, which are three switches.

[0019] The power switch 51 is a slide switch for switching on and off. In FIG. 1, the power switch 51 is in the on state. When the power switch 51 is turned on, power is supplied from the power supply unit 40 to each part such as the display unit 30, the processing unit 10, and the storage unit 70 through an electric circuit (not shown).

[0020] The theme selection switch 52 is a slide switch for selecting the theme of the danger prediction training. In the danger prediction training device 1 of the present embodiment, as shown in FIG. 1, the user can select five themes related to the danger prediction training through the theme selection switch 52. When the slider 54 is moved to the "electricity" position shown in FIG. 1, a theme related to the danger prediction during electrical work (hereinafter referred to as the electrical work theme) is selected. When the slider 54 of the theme selection switch 52 is moved to the "fall" position shown in FIG. 1, a theme related to the danger prediction of the worker's fall during high-altitude work (hereinafter referred to as the high-altitude work theme) is selected. When the slider 54 is moved to the "entanglement" position shown in FIG. 1, a theme related to the danger prediction of the worker being entangled in the machine during work (hereinafter referred to as the entanglement theme) is selected. When the slider 54 is moved to the "lifting" position shown in FIG. 1, a theme related to the danger prediction during lifting work (hereinafter referred to as the lifting theme) is selected. When the slider 54 is moved to the "confined space" position shown in FIG. 1, a theme related to the danger prediction during work in a confined space (hereinafter referred to as the confined space theme) is selected.

[0021] The re-selection switch 53 is a button for re-selecting and displaying a problem. After a problem is displayed on the display unit 30, when the user presses the re-selection switch 53, the processing unit 10 re-selects the problem, and a new problem is displayed on the display unit 30.

[0022] The string-like member 60 is a string extending from the main body 20 and is configured to be attachable to the user's clothing or the like. Thereby, it becomes possible for the user to perform work while carrying the danger prediction training device 1.

[0023] The storage unit 70 is a storage area for various programs and various data for causing the hardware group to function as the danger prediction training device 1, and can be configured by a ROM, a RAM, a flash memory, a semiconductor drive (SSD), or a hardware (HDD), etc. Specifically, the storage unit 70 stores a program for causing the processing unit 10 to execute each function of the present embodiment, a control program for danger prediction training, a theme of danger prediction training, and a plurality of questions regarding danger prediction training for each theme. In the present embodiment, the storage unit 70 stores an electrical work theme, a high-place work theme, an entanglement theme, a lifting theme, and a confined space theme as themes of danger prediction training. Note that the themes stored in the storage unit 70 are not particularly limited, and questions regarding themes other than the above-mentioned types may be stored.

[0024] The processing unit 10 is an arithmetic device configured by a processor, and reads various programs and data from the storage unit 70 and executes predetermined data processing. The processor is, for example, a CPU (central processing unit), an MPU (micro processing unit), an SoC (system on a chip), a DSP (digital signal processor), a GPU (graphics processing unit), a VPU (vision processing unit), an ASIC (application specific integrated circuit), a PLD (programmable logic device), or an FPGA (field-programmable gate array), etc. Note that the processing unit 10 and the storage unit 70 are built in the main body 20. Note that the processing unit 10 is electrically connected to the display unit 30, the power supply unit 40, the operation unit 50, and the storage unit 70 via an electric circuit.

[0025] As shown in FIG. 2, the processing unit 10 includes a theme reception unit 11 and a display control unit 12. Note that in this embodiment, the danger prediction training device 1 does not have a communication function for communicating with other devices.

[0026] The theme reception unit 11 executes a process of receiving an operation by the user via the theme selection switch 52 and the re-selection switch 53 of the operation unit 50. The theme reception unit 11 receives information about the theme selected by the user via the operation unit 50 and information such as whether the re-selection switch 53 has been pressed, and transmits it to the display control unit 12.

[0027] The display control unit 12 executes a process of randomly displaying a plurality of questions in the theme received by the theme reception unit 11 on the display unit 30. By randomly displaying from a plurality of questions, the question tendency does not become a single pattern compared to the case of artificial selection, and it is possible to prevent the user from getting used to the questions of the danger prediction training.

[0028] The questions displayed on the display unit 30 are displayed, for example, as images, character information, etc. indicating situations where danger lurks during work. The user can check the questions displayed on the display unit 30 and consider the danger lurking in the situation shown by the image, the method for avoiding the occurrence of the danger, and the countermeasures in case the danger occurs.

[0029] Here, for the danger prediction training, it is desirable to perform the danger prediction training at a certain frequency in order to maintain a high awareness of the safety of the workers. However, in power plants and the like, the bringing in of electronic devices is severely restricted for reasons such as safety. For example, in a workplace where explosive gas exists, etc., the bringing in of electronic devices without an explosion-proof function may be prohibited. When workers work for a long time in such a place, it is necessary for the workers to leave the workplace once in order to perform the danger prediction training using electronic devices.

[0030] The risk prediction training device 1 of this embodiment has an explosion-proof function, and this explosion-proof function is realized by a housing 80 having an explosion-proof structure. With this configuration, it is possible to bring in the risk prediction training device 1 even in a place where explosive gases or the like exist in a power plant.

[0031] The housing 80 having an explosion-proof structure will be described. The housing 80 houses the main body 20 inside it. Specifically, a part of the display unit 30, power supply unit 40, operation unit 50, processing unit 10, storage unit 70, and cord-like member 60 provided in the main body 20 is housed in the housing 80. The housing 80 in this embodiment is sized to be housed in a pocket or the like of a user's clothing and is portable.

[0032] In this embodiment, the housing 80 has a pressure-resistant explosion-proof structure with a fully enclosed structure that houses the main body 20. Specifically, the housing 80 has a strength to withstand the pressure of an explosion even if an explosion occurs inside it, and has a structure such that flames or the like generated by the explosion do not escape from the housing 80 and do not ignite the surrounding explosive gases.

[0033] The explosion-proof structure of the housing 80 may be, for example, an increased safety explosion-proof structure, a resin-filled explosion-proof structure, or a non-sparking explosion-proof structure.

[0034] The increased safety explosion-proof structure is a structure with high mechanical strength against damage from the outside of the housing 80, insulation performance to prevent insulation degradation, and safety measures to suppress the generation of high temperatures. The resin-filled explosion-proof structure is a structure in which the housing 80 is composed of a thermosetting resin, a thermoplastic resin, or the like, and the main body 20 and the like are housed in the resin so as not to ignite explosive gases. The non-sparking explosion-proof structure is a structure in which, for example, parts that may be ignition sources such as the power supply unit 40 and electrical circuits are protected so as not to ignite explosive gases.

[0035] According to the embodiment described above, the following effects are achieved.

[0036] The risk prediction training device 1 according to this embodiment includes a storage unit 70 that stores a plurality of questions regarding risk prediction training for each predetermined theme, and a processing unit 10 that receives a theme selected by a user and randomly displays a plurality of questions in the received theme on a display unit, and has an explosion-proof function. Thus, since the risk prediction training device 1 has an explosion-proof function, even in a power plant or the like where the bringing in of electronic devices is severely restricted, it is possible to perform risk prediction training using the risk prediction training device 1 without bringing in paper or the like instead of electronic devices. Therefore, it is possible to easily perform risk prediction training in more environments.

[0037] Also, in the risk prediction training device 1 according to this embodiment, the explosion-proof function is realized by a housing 80 that houses the storage unit 70, the display unit 30, and the processing unit 10 and has an explosion-proof structure. Thus, even in a place where stricter standards are provided where explosive gases or the like may exist, it is possible to easily perform risk prediction training using the risk prediction training device 1.

[0038] Also, the risk prediction training device 1 according to this embodiment does not have a communication function for communicating with other devices. Thus, even in a place where the bringing in of communication devices is prohibited, since it does not have a communication function, it is possible to perform risk prediction training using the risk prediction training device 1.

[0039] Also, the risk prediction training device 1 according to this embodiment is portable. Thus, the risk prediction training device 1 can be more easily carried and used.

[0040] As described above, one embodiment of the present invention has been described, but the present invention is not limited to this. Within the scope of the gist of the present invention, the detailed configuration may be appropriately changed.

[0041] In the above embodiment, the danger prediction training device 1 included the housing 80, but it may have a configuration with an explosion-proof function without the housing 80. For example, the danger prediction training device 1 may have a configuration with an intrinsically safe explosion-proof structure. Specifically, it may have a safety holding circuit that reduces the energy released from the electrical circuit in the main body 20 during faults such as short circuits, ground faults, and open circuits, and may be configured not to ignite explosive gas even during a fault.

[0042] Also, for example, the danger prediction training device 1 may have a configuration in which a safety holding circuit is provided in the electronic circuit in the main body 20 while including the housing 80. Thereby, since the explosion-proof function of the danger prediction training device 1 can be enhanced, danger prediction training can be performed using the danger prediction training device 1 even in a place where the bringing in of electronic devices is more strictly restricted.

[0043] Also, for example, the danger prediction training device 1 may have a waterproof function together with the explosion-proof function. Thereby, even in an environment where the electronic device may get wet with water, danger prediction training can be easily performed using the danger prediction training device 1.

[0044] Also, in the above embodiment, the danger prediction training device 1 was a device in which a theme related to danger prediction training in a power plant was stored, but the theme stored in the storage unit 70 is not particularly limited. For example, it may be a theme related to traffic such as driving a vehicle, or a theme related to building construction.
