Technical Field

[0001] The present invention relates to a cubicle protection system and a cubicle system.

Background Art

[0002] A cubicle (cubicle type high voltage power receiving equipment) is high voltage power receiving equipment in which various devices and apparatuses are housed in a metal casing (see Patent Document 1). In conventional cubicles, measures against abnormal weather such as storms and heavy rain have been taken by adding rain shields to the ventilation openings, installing drain outlets, and shielding both sides of the wooden foundation with shields.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, the measure of installing a rain shield against a storm is not an effective measure against rain carried by strong winds such as side-on rain, and rainwater may enter the inside of the cubicle housing. In this case, when rainwater adheres to the high voltage equipment (electrical equipment) inside the cubicle housing, the insulating material provided in the high voltage equipment (electrical equipment) may deteriorate and insulation breakdown may occur, leading to a possible short circuit. In addition, the cubicle of Patent Document 1 does not have sufficient measures against a rainfall state in which the risk of rainwater directly entering the cubicle is increased due to abnormal weather (for example, heavy rainfall, storm, etc.).

[0005] Therefore, in the conventional cubicle and the cubicle of Patent Document 1, when the rainfall state is a rainfall state (for example, guerrilla heavy rain, storm, etc.) in which the risk of rainwater directly entering the cubicle increases, rainwater may directly enter the interior of the cubicle housing.

[0006] The present invention has been made to solve the above problems. That is, one of the objects of the present invention is to provide a cubicle protection system and a cubicle system that can reduce the possibility of rainwater entering the interior of the cubicle housing when the rainfall state is such that the risk of rainwater directly entering the cubicle increases.

Means for Solving the Problems

[0007] In order to solve the above problems, the cubicle protection system of the present invention includes a processing unit that acquires meteorological information related to precipitation and installation position information of the cubicle, and a shutter that has a ventilation opening and performs a closing operation to close the ventilation opening and an opening operation to open the ventilation opening, and a control unit that controls the operation of the shutter of the cubicle, wherein the processing unit and the control unit of the cubicle are communicably configured, and the processing unit determines the rainfall state of the installation position of the cubicle based on the meteorological information related to precipitation and the installation position information of the cubicle, and based on the determined rainfall state, the control unit operates the shutter so that the shutter is in either the closed state or the open state.

[0008] The cubicle system of the present invention includes a processing unit that acquires weather information related to precipitation and installation position information of the cubicle, a shutter in which a ventilation opening is formed and that performs a closing operation to close the ventilation opening and an opening operation to open the ventilation opening, and a control unit that controls the operation of the shutter of the cubicle. The cubicle system is configured such that the processing unit and the control unit of the cubicle can communicate with each other. The processing unit determines the rainfall state at the installation position of the cubicle based on the weather information related to precipitation and the installation position information of the cubicle, and based on the determined rainfall state, causes the control unit to operate the shutter so that the shutter is in either the closed state or the open state.

Advantages of the Invention

[0009] According to the present invention, when it is a rainfall state in which the risk of rainwater directly entering the cubicle is increased, it is possible to reduce the possibility of rainwater entering the interior of the housing of the cubicle. Note that the effects described here are not necessarily limited, and may be any of the effects described in the present disclosure.

Embodiments for Carrying Out the Invention

[0011] <Background> First, to facilitate understanding of the present invention, the technical background of the present invention will be described. Due to recent abnormal weather, there is a need for countermeasures against the increasing risk of rainwater directly entering the cubicle due to guerrilla heavy rain or storms.

[0012] In response to this, the inventors of the present application have considered a cubicle system that can respond to guerrilla heavy rain or storms by opening and closing the shutter of the ventilation port (ventilation opening) in real time according to the weather conditions or weather forecast at the cubicle installation location based on weather information related to precipitation obtained from a rain cloud radar or the like. On the other hand, in a cubicle, since air circulation inside the panel is necessary, it is not preferable to completely seal the housing and maintain that state for a long period of time.

[0013] Therefore, an object of the present invention is to protect the cubicle from rainwater while ensuring air circulation inside the panel by appropriately automatically opening and closing the shutter of the ventilation port (ventilation opening) as needed.

[0014] Hereinafter, each embodiment of the present invention will be described with reference to the drawings. In all the drawings of the embodiments, the same or corresponding parts may be denoted by the same reference numerals. In the following description, the CPU may be used as the subject to describe the processing (operation), but the subject of the processing may be the device (server or control device) instead of the CPU. In the following description, the device (server or control device) may be used as the subject to describe the processing (operation), but the CPU may be used instead of the device (server or control device).

[0015] <<First Embodiment>> The cubicle system according to the first embodiment of the present invention will be described. FIG. 1 is a system configuration diagram showing a configuration example of the cubicle system according to the first embodiment of the present invention. As shown in FIG. 1, the cubicle system includes an information distribution server 100, a management server 200, and a cubicle type high voltage power receiving facility 300 (hereinafter referred to as "cubicle 300").

A system including the management server 200 and the cubicle 300 may also be referred to as a cubicle system.

[0016] The information distribution server 100 and the management server 200 are connected so as to be able to transmit and receive information via the network NW1 (configured to be communicable). The management server 200 and the control device 310 included in the cubicle 300 are connected so as to be able to transmit and receive information to and from each other via a wireless LAN (configured to be communicable).

[0017] The information distribution server 100 acquires rain cloud information as meteorological information regarding precipitation from the rain cloud radar AN1, and sequentially transmits the rain cloud information to the management server 200. The rain cloud information includes information indicating current or future rain clouds and precipitation ranges, information indicating the current or future precipitation situation (current or future precipitation amount, current or future precipitation intensity (precipitation amount per unit time (one hour))), and the like. Note that the information distribution server 100 may acquire meteorological information regarding wind speed from other meteorological observation means, and sequentially transmit information regarding wind speed to the management server 200.

[0018] FIG. 2 is a diagram showing an example of the hardware configuration of the management server 200. The management server 200 is a server that manages the control of the shutter 340 (see FIG. 3) that closes and opens the ventilation port 334 (which may also be referred to as a “ventilation port”) of the cubicle 300.

[0019] The management server 200 includes a CPU 211, a ROM 212, a RAM 213, a non-volatile storage device 214 capable of reading and writing data, a network interface 215, an input / output interface 216, and the like.

[0020] The CPU 211 loads various programs (not shown) stored in the ROM 212 and / or the storage device 214 into the RAM 213, and realizes various functions by executing the programs loaded into the RAM 213. As described above, various programs executed by the CPU 211 are loaded into the RAM 213, and data used when the CPU 211 executes various programs is temporarily stored. The ROM 212 and / or the storage device 214 are non-volatile storage media, and various programs are stored in the ROM 212 and / or the storage device 214.

The input / output interface 216 is an interface for connecting to a keyboard, a display device, and the like. The display device is a display capable of displaying images.

[0023] Note that for the management server 200, a hardware device partially or entirely configured by an FPGA (Field Programmable Gate Array) or the like may be used. Also, the management server 200 may be composed of a plurality of servers, or may be a virtual computer constructed on the cloud.

[0024] FIG. 3 is a diagram showing a configuration example of the cubicle 300. The cubicle 300 includes a metal housing 320, a roof portion 330, and various devices such as a transformer disposed inside the metal housing 320. Since these devices are well-known, the description thereof is omitted.

[0025] In the roof portion 330, a ventilation passage 331 communicating with the internal space of the metal housing 320 is formed. A partition wall 332 is provided in the ventilation passage 331. The ventilation passage 331 is divided by the partition wall 332 into an outer roof portion 330a and an inner roof portion 330b.

[0026] A ventilation opening 333 penetrating the partition wall 332 is formed in the partition wall 332. A ventilation port 334 communicating the inside and the outside of the roof portion 330 is provided on the lower surface of the outer roof portion 330a. A rain guard 335, which is a member for preventing rainwater from entering the interior, is provided on the outer roof portion 330a.

[0027] A shutter 340 operable between a fully closed position for completely closing the ventilation opening 334 and a fully open position for opening the ventilation opening 334 is attached to the roof portion 330. Note that the state of the shutter 340 when it is in the fully closed position and closes the ventilation opening 334 is referred to as the "closed state", and the state of the shutter 340 when it is in the fully open position and the ventilation opening 334 is open (does not close the ventilation opening 334) is referred to as the "open state". Note that FIG. 3 shows the closed state in which the shutter 340 is in the fully closed position.

[0028] A control device 310 and a shutter drive device 360 are provided in the metal housing 320. The control device 310 includes a CPU 311, a ROM 312, a RAM 313, a non-volatile storage device 314 capable of reading and writing data, a network interface 315, an input / output interface 316, and the like. These are communicably connected to each other via a bus (not shown).

[0029] The CPU 311 loads various programs (not shown) stored in the ROM 312 and / or the storage device 314 into the RAM 313, and realizes various functions by executing the programs loaded into the RAM 313. As described above, various programs executed by the CPU 311 are loaded into the RAM 313, and data used when the CPU 311 executes various programs is temporarily stored. The ROM 312 and / or the storage device 314 are non-volatile storage media, and various programs are stored in the ROM 312 and / or the storage device 314.

[0030] The network interface 315 is an interface for connecting the control device 310 to a wireless LAN. The input / output interface 316 is an interface for connecting to a keyboard, a display device, and the like. The display device is a display capable of displaying an image.

[0031] Note that, as for the control device 310, a hardware device partially or entirely constituted by an FPGA (Field Programmable Gate Array) or the like may be used. The control device 310 may be referred to as a "control unit" for convenience.

[0032] The shutter drive device 360 includes a motor 361 driven by electric power supplied from a power source (not shown) and a shutter opening / closing mechanism 362. The shutter drive device 360 rotates the motor 361 in the first direction, and moves the shutter 340 to the fully open position via the shutter opening / closing mechanism 362, thereby opening the shutter 340. The shutter drive device 360 rotates the motor 361 in the second direction, which is the direction opposite to the first direction, and moves the shutter 340 to the fully closed position via the shutter opening / closing mechanism 362, thereby closing the shutter 340.

[0033] <Summary> The information distribution server 100 transmits rain cloud information to the management server 200. The management server 200 receives the rain cloud information. The management server 200 determines the rainfall state at the installation position of the cubicle 300 indicated by the installation position information based on the rain cloud information and the installation position information stored in the storage device 314. The management server 200 determines whether the rainfall state at the installation position of the cubicle 300 is clear or light rain or more. When the rainfall state at the installation position of the cubicle 300 is light rain or more, the management server 200 determines whether the rainfall state at the installation position of the cubicle 300 is heavy rain or more or light rain.

[0034] For example, when the precipitation intensity indicated by the rain cloud information (that is, the precipitation amount per hour) is less than the first threshold value, the management server 200 determines that the rainfall state is clear. When the precipitation intensity indicated by the rain cloud information is equal to or greater than the first threshold value, the management server 200 determines that the rainfall state is light rain or more. When the precipitation intensity indicated by the rain cloud information is equal to or greater than the second threshold value, the management server 200 determines that the rainfall state is heavy rain or more. When the precipitation intensity is equal to or greater than the first threshold value and less than the second threshold value, the management server 200 determines that the rainfall state is light rain.

[0035] Based on the Japan Meteorological Agency's terminology for rain intensity, it is defined as follows: When the amount of precipitation (one hour rainfall) (i.e., precipitation intensity) is zero or very light, it is defined as clear. When the amount of precipitation (one hour rainfall) is greater than very light and less than 10 mm, it is defined as light rain or weak rain.

[0036] Rainfall conditions with a precipitation amount (one-hour rainfall amount) of 10 mm or more and less than 20 mm are defined as "slightly heavy rain." In terms of how people imagine this rainfall condition, it is like a downpour. Rainfall conditions with a precipitation amount (one-hour rainfall amount) of 20 mm or more and less than 30 mm are defined as "heavy rain." In terms of how people imagine this rainfall condition, it is like a downpour. Rainfall conditions with a precipitation amount (one-hour rainfall amount) of 30 mm or more and less than 50 mm are defined as "heavy rain." In terms of how people imagine this rainfall condition, it is like a bucket being overturned. Rainfall conditions with a precipitation amount (one-hour rainfall amount) of 50 mm or more and less than 80 mm are defined as "very heavy rain." In terms of how people imagine this rainfall condition, it is like a waterfall. Rainfall conditions with a precipitation amount (one-hour rainfall amount) of 80 mm or more are defined as "torrential rain." When this rainfall condition is expressed in terms of the image that a person has, it is a state of oppression that makes it difficult to breathe and causes fear.

[0037] In this example, "heavy rain or more" refers to, for example, a state of "heavy rain" or more according to the above definition. A rainfall state of "light rain or more" refers to, for example, a state of "light rain" or "weak rain" or more according to the above definition. A rainfall state of "light rain" may include a state of "slightly heavy rain" according to the above definition. "Clear" refers to, for example, a state of "clear" according to the above definition. The first threshold and the second threshold may be set to any value with reference to, for example, the above precipitation amount (one-hour rainfall amount). As an example, the first threshold is, for example, 3 mm / h, and the second threshold is, for example, 20 mm / h.

[0038] Note that, as terms expressing rainfall conditions, a guerrilla heavy rain refers to local heavy rain or concentrated heavy rain. Local heavy rain refers to rain that suddenly falls strongly and brings about a rainfall amount of about several tens of millimeters in a narrow area within a short period of several tens of minutes. Concentrated heavy rain refers to rain that strongly falls at the same location over several hours and brings about a rainfall amount of 100 mm to several hundred millimeters. A storm refers to a meteorological condition in which strong winds and heavy rain occur. Therefore, it can be said that these rainfall conditions are included in the state of "heavy rain or above".

[0039] When the rainfall condition at the installation position of the cubicle 300 is clear, the management server 200 transmits a command to the control device 310 so that the shutter 340 is in an open state where it does not close the ventilation port 334. When receiving the command from the management server 200, if the shutter 340 is in the fully closed position, the control device 310 rotates the motor 361 of the shutter drive device 360 in the first direction to move the shutter 340 to the fully open position. Note that when the shutter 340 is in the fully open position, the control device 310 maintains the shutter 340 in the fully open position without rotating the motor 361. Operating so that the shutter 340 is in an open state in this way is referred to as "the shutter 340 performs an opening operation".

[0040] When the rainfall condition at the installation position of the cubicle 300 is light rain or above and not heavy rain or above (that is, in the case of light rain), the management server 200 similarly transmits a command to the control device 310 so that the shutter 340 is in an open state where it does not close the ventilation port 334. When receiving the command from the management server 200, the control device 310 controls so that the shutter 340 performs an opening operation.

[0041] When the rainfall state at the installation location of the cubicle 300 is heavy rain or more, there is a possibility that rainwater may enter the inside of the metal housing 320. Therefore, in this case, the management server 200 sends a command to the control device 310 so that the shutter 340 is in a closed state where it closes the ventilation opening 334. When the control device 310 receives a command from the management server 200, if the shutter 340 is in the fully open position, it rotates the motor 361 of the shutter drive device 360 in the second direction to move the shutter 340 to the fully closed position. Note that when the shutter 340 is in the fully closed position, the control device 310 maintains the shutter 340 in the fully closed position without rotating the motor 361. Operating so that the shutter 340 is in the closed state in this way is referred to as "the shutter 340 performs a closing operation".

[0042] When the rainfall state is heavy rain or more, the cubicle system can take appropriate measures to prevent rainwater from directly entering the cubicle 300 by closing the ventilation opening 334 with the shutter 340 in a situation where the risk of rainwater directly entering the cubicle 300 is increasing (for example, in situations such as guerrilla heavy rain or storms). On the other hand, when the risk of rainwater directly entering the cubicle 300 is low or there is no risk (for example, in sunny or light rain conditions), the cubicle system can appropriately ventilate the inside of the metal housing 320 by opening the shutter 340 to an open state and opening the ventilation opening 334.

[0043] <Specific operation> Figure 4 is a flowchart showing the processing flow executed by the CPU 211 of the management server 200. The CPU 211 repeatedly executes the processing flow shown in Figure 4 every time a predetermined time elapses. The CPU 211 starts processing from step 400 in Figure 4, sequentially executes the processing of steps 405 and 410 described below, and then proceeds to step 415.

[0044] Step 405: The CPU 211 receives rain cloud information from the information distribution server 100.

[0045] Step 410: The CPU 211 acquires the installation position information of the cubicle 300 from the storage device 214 of the management server 200.

[0046] When the CPU 211 proceeds to step 415, it determines whether the current rainfall state at the installation position of the cubicle 300 is light rain or more based on the rain cloud information and the installation position information of the cubicle 300.

[0047] If the current rainfall state at the installation position of the cubicle 300 is not light rain or more, the CPU 211 determines "NO" in step 415, proceeds to step 420, and sends a command to the control device 310 of the cubicle 300 so that the shutter 340 remains in the open state without closing the ventilation opening 334. When receiving the command, the control device 310 controls the operation of the shutter 340 so that the shutter 340 is in the open state by controlling the motor 361 of the shutter drive device 360 as described above. Then, the CPU 211 proceeds to step 495 and temporarily ends this processing flow.

[0048] If the current rainfall state at the installation position of the cubicle 300 is light rain or more, the CPU 211 determines "YES" in step 415, proceeds to step 425, and determines whether the current rainfall state at the installation position of the cubicle 300 is heavy rain or more based on the rain cloud information and the installation position information of the cubicle 300.

[0049] If the current rainfall state at the installation position of the cubicle 300 is not heavy rain or more (i.e., the rainfall state is light rain), the CPU 211 determines "NO" in step 425, proceeds to step 420, executes the processing of step 420 as described above, and then proceeds to step 495 to temporarily end this processing flow.

[0050] When the current rainfall condition at the installation location of the cubicle 300 is heavy rain or more, the CPU 211 determines "YES" in step 425 and proceeds to step 430, and sends a command to the control device 310 of the cubicle 300 so that the shutter 340 closes the ventilation opening 334. When receiving the command, the control device 310 controls the operation of the shutter 340 so that the shutter 340 is in the closed state by controlling the motor 361 of the shutter drive device 360 as described above. Thereafter, the CPU 211 proceeds to step 495 and temporarily ends this processing flow.

[0051] <Effect> As described above, when the current rainfall condition at the installation location of the cubicle system according to the first embodiment of the present invention is a rainfall condition in which the risk of rainwater directly entering the cubicle 300 is increased, the control device 310 can reduce the possibility of rainwater entering the interior of the housing of the cubicle 300 by closing the shutter 340. The cubicle system according to the first embodiment can quickly close the shutter 340 according to the current rainfall condition (heavy rain or more). Therefore, even when the rainfall condition suddenly changes drastically to heavy rain or more (for example, guerrilla heavy rain), the possibility of rainwater entering the interior of the housing of the cubicle 300 can be reduced. Further, since the cubicle system according to the first embodiment can open the shutter 340 according to the current rainfall condition (light rain or sunny), ventilation inside the cubicle 300 can be ensured.

[0052] <<Second Embodiment>> The cubicle system according to the second embodiment of the present invention will be described. The cubicle system according to the second embodiment has differences from the cubicle system according to the first embodiment only in the following points. · The cubicle system according to the second embodiment arranges a space heater 501 and a water droplet detection sensor 502 in the cubicle 300, and when the water droplet detection sensor 502 detects water droplets in the cubicle 300, the space heater 501 is operated to dry the interior of the cubicle 300.

[0053] The following will focus on explaining this difference.

[0054] FIG. 5 is a diagram showing a configuration example of a cubicle 300 to which a cubicle system according to the second embodiment is applied. As shown in FIG. 5, the cubicle 300 includes a space heater 501 and a water droplet detection sensor 502. The space heater 501 and the water droplet detection sensor 502 are connected to the control device 310 so as to be able to transmit and receive information. Otherwise, it is the same as the cubicle 300 of the first embodiment.

[0055] The space heater 501 is a small electric heater for heating the space inside the metal housing 320 of the cubicle 300. The space heater 501 can be controlled by the control device 310 to be either in an ON or OFF operating state.

[0056] The water droplet detection sensor 502 is a sensor installed at a predetermined location inside the cubicle 300 for detecting (sensing) water droplets (condensation). The water droplet detection sensor 502 transmits a detection signal indicating whether water droplets have been detected to the control device 310. The control device 310 can determine whether water droplets are present inside the cubicle 300 based on the detection signal.

[0057] <Specific operation> FIG. 6 is a flowchart showing a processing flow executed by the CPU 311 of the control device 310. The CPU 211 of the management server 200 of the cubicle system repeatedly executes the processing flow shown in FIG. 4 described above every time a predetermined time elapses. Further, the CPU 311 of the control device 310 of the cubicle 300 repeatedly executes the processing flow shown in FIG. 6 every time a predetermined time elapses. The CPU 311 starts processing from step 600 in FIG. 6 and proceeds to step 605 to acquire a detection signal from the water droplet detection sensor 501.

[0058] Thereafter, the CPU 311 proceeds to step 610 and determines whether water droplets have been detected based on the detection signal.

[0059] When water droplets are detected, the CPU 311 determines "YES" in step 610, proceeds to step 615, and activates (turns ON) the space heater 501. Then, the CPU 311 proceeds to step 695 and temporarily ends this processing flow.

[0060] When no water droplets are detected, the CPU 311 determines "NO" in step 610, stops (turns OFF) the space heater 501, proceeds to step 695, and temporarily ends this processing flow.

[0061] <Effect> As described above, the cubicle system according to the second embodiment of the present invention has the same effects as the first embodiment. Furthermore, the cubicle system according to the second embodiment can remove moisture inside the cubicle 300 by heating and drying the inside of the cubicle 300 with the space heater 501 when water droplets are detected.

[0062] <<Third Embodiment>> The cubicle system according to the third embodiment of the present invention will be described. The cubicle system according to the third embodiment has differences from the cubicle system according to the first embodiment only in the following points. · As shown in FIG. 7, the cubicle system according to the third embodiment arranges a rain gauge 700 in the cubicle 300, measures the precipitation intensity with the rain gauge 700, and opens and closes the shutter 340 based on the measured precipitation intensity.

[0063] Hereinafter, the description will be centered on this difference.

[0064] <Specific Operation> FIG. 8 is a flowchart showing a processing flow executed by the CPU 311 of the control device 310. The CPU 211 of the management server 200 of the cubicle system repeatedly executes the processing flow shown in FIG. 4 described above every time a predetermined time elapses. Further, the CPU 311 of the control device 310 of the cubicle 300 repeatedly executes the processing flow shown in FIG. 8 every time a predetermined time elapses. The CPU 311 starts processing from step 800 in FIG. 8 and proceeds to step 805 to acquire the precipitation intensity from the rain gauge 700.

[0065] Thereafter, the CPU 311 proceeds to step 810 and determines whether the rainfall state is heavy rain or more based on the precipitation intensity. If the rainfall state is heavy rain or more, the CPU 311 determines "YES" in step 810 and proceeds to step 815, and controls the operation of the shutter 340 so that the shutter 340 closes the ventilation port 334 to be in a closed state by controlling the motor 361 of the shutter drive device 360. Thereafter, the CPU 311 proceeds to step 895 and once terminates this processing flow.

[0066] If the rainfall state is not heavy rain or more, the CPU 311 determines "NO" in step 810 and proceeds to step 820, and controls the operation of the shutter 340 so that the shutter 340 does not close the ventilation port 334 to be in an open state by controlling the motor 361 of the shutter drive device 360.

[0067] <Effect> As described above, the cubicle system according to the third embodiment of the present invention has the same effects as the first embodiment. Further, the cubicle system according to the third embodiment executes the opening and closing of the shutter 340 according to the precipitation intensity measured by the rain gauge 700 in addition to the opening and closing of the shutter 340 based on the rain cloud information. Thereby, the cubicle system according to the third embodiment can complement the opening and closing of the shutter 340 according to the rainfall state determined based on the rain cloud information, and perform the opening and closing of the shutter 340. Thereby, when the rainfall state is a rainfall state in which the risk of rainwater directly entering the cubicle 300 is increasing, the cubicle system according to the third embodiment can further reduce the possibility of rainwater entering the inside of the housing of the cubicle 300.

[0068] <<Fourth Embodiment>> The cubicle system according to the fourth embodiment of the present invention will be described. The cubicle system according to the fourth embodiment has differences from the cubicle system according to the first embodiment only in the following points. · In the cubicle system according to the fourth embodiment, the management server 200 determines the current rainfall state using weather information regarding wind speed in addition to the rain cloud information. · As shown in FIG. 9, the cubicle system according to the fourth embodiment includes a shutter fixing mechanism 363 in the shutter driving device 360. When it is determined that the current rainfall state is a storm, the shutter fixing mechanism 363 is operated to fix the shutter 340 in a closed state.

[0069] Hereinafter, the description will focus on this difference.

[0070] <Specific Operation> FIG. 10 is a flowchart showing a processing flow executed by the CPU 211 of the management server 200. The CPU 211 repeatedly executes the processing flow shown in FIG. 10 every time a predetermined time elapses. The CPU 211 starts the processing from step 1000 in FIG. 10, sequentially executes the processing of step 1005 and step 1010 described below, and then proceeds to step 1015.

[0071] Step 1005: The CPU 211 receives rain cloud information and weather information regarding wind speed from the information distribution server 100.

[0072] Step 1010: The CPU 211 acquires the installation position information of the cubicle 300 from the storage device 314.

[0073] When the CPU 211 proceeds to step 1015, it determines whether the current rainfall state at the installation position of the cubicle 300 is light rain or more based on the rain cloud information and the installation position information of the cubicle 300.

[0074] If the current rainfall state at the installation position of the cubicle 300 is not light rain or more, the CPU 211 determines "NO" in step 1015, proceeds to step 1020, and transmits a command to the control device 310 of the cubicle 300 so that the shutter 340 remains in the open state without closing the ventilation opening 334. When receiving the command, the control device 310 controls the operation of the shutter 340 so that the shutter 340 is in the open state by controlling the motor 361 of the shutter drive device 360 as described above. Thereafter, the CPU 211 proceeds to step 1095 and once terminates this processing flow.

[0075] If the current rainfall state at the installation position of the cubicle 300 is light rain or more, the CPU 211 determines "YES" in step 1015, proceeds to step 1025, and determines whether the current rainfall state at the installation position of the cubicle 300 is heavy rain or more based on the rain cloud information and the installation position information of the cubicle 300.

[0076] If the current rainfall state at the installation position of the cubicle 300 is not heavy rain or more (i.e., if it is light rain), the CPU 211 determines "NO" in step 1025, proceeds to step 1020, executes the processing of the aforementioned step 1020, and then proceeds to step 1095 to once terminate this processing flow.

[0077] When the current rainfall state at the installation location of the cubicle 300 is heavy rain or more, the CPU 211 determines "YES" in step 1025 and proceeds to step 1030. Based on the weather information regarding wind speed and the installation location information of the cubicle 300, it determines whether the current wind speed at the installation location of the cubicle 300 indicated by the weather information regarding wind speed is equal to or greater than a predetermined threshold value, thereby determining whether the current rainfall state at the installation location of the cubicle 300 is a storm. That is, when the current wind speed at the installation location of the cubicle 300 indicated by the weather information regarding wind speed is equal to or greater than the predetermined threshold value, it is determined that the current rainfall state at the installation location of the cubicle 300 is a storm. When the current wind speed at the installation location of the cubicle 300 indicated by the weather information regarding wind speed is less than the predetermined threshold value, it is determined that the current rainfall state at the installation location of the cubicle 300 is not a storm.

[0078] When the current rainfall state at the installation location of the cubicle 300 is a storm, the CPU 211 determines "YES" in step 1030 and proceeds to step 1035, and sends a command to the control device 310 of the cubicle 300 so that the shutter 340 is fixed in a closed state where it closes the ventilation opening 334. When receiving the command, the control device 310 controls the operation of the shutter 340 so that the shutter 340 is in a closed state by controlling the motor 361 of the shutter drive device 360 as described above, and operates the shutter fixing mechanism 363 to fix the shutter 340 in a closed state. Thereafter, the CPU proceeds to step 1095 and temporarily ends this processing flow.

[0079] When the current rainfall state at the installation location of the cubicle 300 is not a storm, the CPU 211 determines "NO" in step 1030 and proceeds to step 1040, and sends a command to the control device 310 of the cubicle 300 so that the shutter 340 is in a closed state (and not fixed) closing the ventilation opening 334. When receiving the command, the control device 310 controls the operation of the shutter 340 so that the shutter 340 is in the closed state by controlling the motor 361 of the shutter drive device 360 as described above. Thereafter, the CPU proceeds to step 1095 and once terminates this processing flow.

[0080] <Effect> As described above, the cubicle system according to the fourth embodiment of the present invention has the same effects as the first embodiment. Further, the cubicle system according to the fourth embodiment of the present invention closes the shutter 340 when the current rainfall state is a rainfall state in which the risk of rainwater directly entering the cubicle 300 is increasing based on the weather information regarding the rain cloud information and the wind speed, and when the current rainfall state at the installation location of the cubicle 300 is a storm, fixes the shutter 340 in the closed state. Thereby, the cubicle system according to the fourth embodiment can reduce the possibility that rainwater enters the inside of the housing of the cubicle 300 even when the rainfall state is a storm.

[0081] <<Fifth Embodiment>> A configuration example of the cubicle system according to the fifth embodiment of the present invention will be described. FIG. 11 is a system configuration diagram showing a configuration example of the cubicle system according to the fifth embodiment of the present invention. As shown in FIG. 11, the cubicle system includes an information distribution server 100, a management server 200, a cubicle 300, and a mobile terminal 1100.

[0082] The information distribution server 100 and the management server 200 are connected so as to be able to transmit and receive information via the network NW1 (configured to be communicable). The management server 200, the control device 310 included in the cubicle 300, and the mobile terminal 1100 are connected so as to be able to transmit and receive information to and from each other via a wireless LAN (configured to be communicable).

[0083] The mobile terminal 1100 is a small and portable electronic device, such as a smartphone or a tablet. The mobile terminal 1100 has a microcomputer and a display device, and provides advanced computing, information processing, and communication functions. As an example of the hardware configuration of the microcomputer, the same configuration as the hardware configuration shown in FIG. 2 can be applied.

[0084] The mobile terminal 1100 can control the operation of the shutter 340 via the control device 310 so that the shutter 340 is either in the closed state or the open state by transmitting a command to the control device 310.

[0085] Similar to the first embodiment, the management server 200 receives rain cloud information from the information distribution server 100 and determines the current rainfall state at the installation location of the cubicle 300. The management server 200 transmits the determination result (i.e., the current rainfall state at the determined installation location of the cubicle 300) to the user's mobile terminal 1100.

[0086] When the mobile terminal 1100 receives the determination result, it displays an image indicating the determination result on the display device (the screen of the mobile terminal 1100). The user who holds the mobile terminal 1100 can check the image indicating the determination result and operate the shutter 340 to be either in the open state or the closed state by remote control. That is, after the user checks the determination result displayed on the screen of the mobile terminal 1100, by operating the mobile terminal 1100 to transmit a command to the control device 310, the shutter 340 can be controlled to move to either the fully closed position or the fully open position according to the determination result.

[0087] <Specific operation> FIG. 12 is a flowchart showing a processing flow executed by the CPU 211 of the management server 200. The CPU repeatedly executes the processing flow shown in FIG. 12 every time a predetermined time elapses. The CPU 211 starts processing from step 1200 in FIG. 12, sequentially executes the processing of steps 1205 to 1220 described below, and then proceeds to step 1295 to temporarily end this processing flow.

[0088] Step 1205: The CPU 211 receives rain cloud information from the information distribution server 100.

[0089] Step 1210: The CPU 211 acquires the installation position information of the cubicle 300 from the storage device 314.

[0090] Step 1215: The CPU 211 determines whether the current rainfall state at the installation position of the cubicle 300 is clear, light rain, or heavy rain or more based on the rain cloud information and the installation position information of the cubicle 300.

[0091] Step 1220: The CPU 211 transmits information indicating the determined rainfall state to the mobile terminal 1100.

[0092] <Effect> As described above, in the cubicle system according to the fifth embodiment of the present invention, when the management server 200 transmits the rainfall state at the installation position of the cubicle 300 to the mobile terminal 1100 capable of remotely operating the shutter 340 of the cubicle 300, in the case of a rainfall state where the risk of rainwater directly entering the cubicle 300 is increased, the user having the mobile terminal 1100 can be prompted to close the shutter 340 by a remote operation based on the operation of the mobile terminal 1100. Thereby, the cubicle system according to the fifth embodiment of the present invention can reduce the possibility of rainwater entering the inside of the housing of the cubicle 300 even when the rainfall state is intense.

[0093] <Modification example of the fifth embodiment> In the first modification of the fifth embodiment, based on the information indicating the determined rainfall state received by the mobile terminal 1100 from the management server 200, there are a first state (first mode) in which a command is automatically transmitted to the control device 310 of the cubicle 300, and a second state (second mode) in which the mobile terminal 1100 transmits a command to the control device 310 of the cubicle 300 based on a user operation. These can be switched by a user operation on the mobile terminal 1100.

[0094] When the mobile terminal 1100 is in the first state, the mobile terminal 1100 operates as follows. That is, when the determined current rainfall state is light rain or clear, the mobile terminal 1100 transmits a command to the control device 310 of the cubicle 300 so that the shutter 340 is in an open state where it does not close the ventilation opening 334. When receiving the command, the control device 310 controls the operation of the shutter 340 so that the shutter 340 is in an open state by controlling the motor 361 of the shutter driving device 360 as described above.

[0095] When the determined current rainfall state of the mobile terminal 1100 is heavy rain or more, the mobile terminal 1100 transmits a command to the control device 310 of the cubicle 300 so that the shutter 340 is in a closed state where it closes the ventilation opening 334. When receiving the command, the control device 310 controls the operation of the shutter 340 so that the shutter 340 is in a closed state by controlling the motor 361 of the shutter driving device 360 as described above.

[0096] When the mobile terminal 1100 is in the second state, the mobile terminal 1100 operates in the same manner as the above-described operation in the fifth embodiment.

[0097] <Second Modification of the Fifth Embodiment> In the second modification of the fifth embodiment, the management server 200 performs the operations described in the fifth embodiment and the same operations as in the first embodiment. That is, in the second modification of the fifth embodiment, in addition to controlling the operation of the shutter 340 by the mobile terminal 1100, the management server 200 controls the operation of the shutter 340.

[0098] Therefore, in the second modification of the fifth embodiment, the management server 200 automatically controls the opening and closing of the shutter 340 via the control device 310 according to the current rainfall state at the installation position of the cubicle 300. Further, in the second modification of the fifth embodiment, based on the judgment of the user who has seen the judgment result of the current rainfall state at the installation position of the cubicle 300 displayed on the screen of the mobile terminal 1100, the user operates the mobile terminal 1100, and thus the opening and closing of the shutter 340 can also be manually controlled.

[0099] Thereby, in the second modification of the fifth embodiment, when the rainfall state is a state where the risk of rainwater directly entering the cubicle 300 is increasing, the possibility of rainwater entering the inside of the housing of the cubicle 300 can be further reduced.

[0100] <<Other Modifications>> The present invention is not limited to the above-described embodiments, and various modifications can be adopted within the scope of the present invention. Further, the above-described embodiments and modifications can be combined with each other as long as they do not depart from the scope of the present invention.

[0101] In each of the first to fourth embodiments described above, the management server 200 may determine the future rainfall state (for example, at a time point after a predetermined time from the present) based on the rain cloud information, and based on the determined rainfall state, cause the control device 310 to operate the shutter 340 so that the shutter 340 is either in the closed state or the open state. For example, when it is determined that the future rainfall state is heavy rain or more, the management server 200 may send a command to the control device 310 so that the shutter 340 is in the closed state at the determined time point, or may send a command to the control device 310 so that the shutter 340 is in the closed state at a future time when the rainfall state becomes heavy rain or more.

[0102] In each of the first to fourth embodiments described above, the management server 200 may be replaced with the mobile terminal 1100, and the mobile terminal 1100 may perform the same operations as the management server 200.

[0103] In the fifth embodiment, the management server 200 may determine the future rainfall state (for example, at a time point after a predetermined time from the present) based on the rain cloud information, or may determine both the future and current rainfall states.

[0104] In the first to fifth embodiments and the modification examples described above, the information distribution server 100 acquires rain cloud information from a rain cloud radar (weather radar). However, the information distribution server 100 may acquire other meteorological information related to precipitation collected by other meteorological observation means such as a meteorological forecasting agency, a meteorological satellite, or a ground meteorological observation station, and transmit it to the management server 200 or the mobile terminal 1100 instead of the rain cloud information. In this case, the management server 200 or the mobile terminal 1100 uses other meteorological information related to precipitation instead of the rain cloud information.
