Description

Highland training cabin

Technical Field

The present invention relates to a highland training compartment including a sports chamber, the inside of which can accommodate a user and sports implements.

Background

When a human body is highly trained by exposure to a low oxygen such as highland hypoxia or a low oxygen partial pressure condition (hereinafter referred to as highland environment), the number of erythrocytes is increased to improve oxygen uptake and supply capacity in response to the highland environment. Thereby, the body's aerobic energy metabolizing capacity is increased. In addition, the endurance training has the effect of increasing the number of muscle mitochondria. When the training is carried out in the high-altitude environment, the maximum oxygen uptake capacity is improved through the synergistic effect, and the whole body endurance is efficiently increased. However, in practice, a person moving in an elevation and training may be time and economically burdensome. Therefore, in order to provide an environment in which training is performed in a highland environment, a device that provides a low oxygen environment has been proposed (for example, patent document 1).

Patent document 1 describes an exercise device (an example of a highland exercise cabin) including a cabin in which an exercise machine such as a treadmill is housed; a sealed cabin mounted on the cabin for covering an upper half of a user's body entering the cabin; a hypoxic gas supply unit that supplies hypoxic gas to the capsule. In the exercise device, when the inside of the capsule is filled with hypoxic gas, the exercise device can be trained under hypoxic conditions as in highland training.

Disclosure of Invention

Problems to be solved by the invention

The highland training chamber described in patent document 1 requires a device for supplying hypoxic gas such as a hypoxic gas supply unit, and the accompanying facilities cause problems of an increase in size and an increase in running cost. Therefore, it is desirable to provide a small and low-cost highland training chamber.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a small and low-cost highland training chamber.

Means for solving the problems

In order to achieve the above object, the highland training chamber according to the present invention includes: a sports chamber having an interior capable of accommodating a user and sports implements; an exhaust pump for exhausting air from the moving chamber; an opening degree adjusting valve for communicating the inside and outside of the motion chamber and capable of adjusting an opening degree; a pressure sensor for detecting a chamber internal pressure of the motion chamber; a gas sensor for detecting a gas composition of the motion chamber; a control unit for controlling the indoor pressure within a preset negative pressure range, wherein the control unit controls the displacement of the exhaust pump and the opening of the opening adjustment valve so that the gas composition obtained from the gas sensor can form a preset ratio.

According to the above configuration, the low oxygen partial pressure environment (hereinafter referred to as "highland environment") can be provided to the user exercising with the exercise equipment by reducing the pressure by adjusting the amount of exhaust from the exhaust pump and the opening of the opening adjusting valve so that the indoor pressure of the exercise chamber is controlled within the preset negative pressure range. With the above configuration, the supply device of the low oxygen gas is not required when the highland environment is provided. Therefore, the high-ground training bay can be made smaller and lower in cost.

According to the above configuration, when providing a highland environment, since the gas composition such as the oxygen partial pressure (concentration) or the carbon dioxide partial pressure (concentration) detected by the gas sensor (for example, an oxygen concentration meter or a carbon dioxide concentration meter) is set to a predetermined ratio by controlling the ventilation conditions such as the exhaust gas amount of the exhaust pump or the opening degree of the opening degree adjustment valve, even when the oxygen in the exercise room is consumed by the exercise of the user, the exercise room is not exposed to an excessively low oxygen environment. That is, a safe highland environment can be realized without imposing an excessive burden on the body of the user. Further, it is possible to avoid the oxygen partial pressure state in which the high upland training effect cannot be sufficiently obtained due to setting of inappropriate ventilation conditions, and it is possible to realize an appropriate upland environment.

The highland training chamber according to the present invention is further characterized in that the air-bleeding pump is a diaphragm pump.

The oxygen partial pressure required for the highland training chamber is, for example, a 17kPa level corresponding to a highland environment with an altitude (height) of 1600m to an altitude of 1800 m. To obtain this oxygen partial pressure, a low vacuum is required to maintain the moving chamber stably at a level of up to 830kPa (absolute pressure). Here, in order to supply stable oxygen to a user, frequent exhaust is required, but when a rotary pump or the like is used as an exhaust pump for frequent exhaust, the vane of the exhaust pump is liable to have a trouble problem. Here, with the above configuration, it is possible to stably maintain a low vacuum, and when an inexpensive diaphragm pump is used as the exhaust pump, it is only necessary to move the flexible diaphragm up and down, and the durability is high.

In the highland training room according to the present invention, the control unit may pulsate the indoor pressure within the preset negative pressure range.

The pulsation of the indoor pressure means that the indoor pressure is reduced and increased (opened) within a predetermined negative pressure range. For example, when the preset negative pressure range is set to be equal to or higher than a first pressure (absolute pressure) and equal to or lower than a second pressure (absolute pressure) lower than the first pressure, the configuration enables the pressure in the exercise chamber to be changed between the first pressure and the second pressure when the user moves in the exercise chamber. Thus, the user can simulate the experience of a state of performing a movement while varying the altitude between a relatively low altitude corresponding to the first pressure and a relatively high altitude corresponding to the second pressure in a high-altitude environment. By simulating such a level of elevation change, a suitable load is applied to the body of the user, and the effect of high-level training can be improved.

In the highland training room according to the present invention, the exercise device includes a movement amount meter for measuring the amount of movement of the user, and the control unit acquires the amount of movement from the movement amount meter and controls the amount of exhaust of the exhaust pump and the opening of the opening adjusting valve in accordance with the amount of movement.

The user consumes oxygen in the exercise room corresponding to the amount of exercise. Here, according to the above configuration, the control unit obtains the amount of exercise of the user by using the amount of exercise meter of the exercise device. The control unit sets ventilation conditions in accordance with the amount of exercise. The control unit described above can realize a suitable highland environment by setting the ventilation condition based on the exercise amount of the user.

The highland training cabin according to the present invention is further characterized by comprising: and a storage unit that stores, as control information, an exhaust gas amount of the exhaust pump and an opening degree of the opening degree adjusting valve, the exhaust gas amount of the exhaust pump and the opening degree of the opening degree adjusting valve being set in correspondence with the motion amount, and the control unit controls the exhaust gas amount of the exhaust pump and the opening degree of the opening degree adjusting valve based on the control information.

According to the above configuration, the control unit can easily set the ventilation condition based on the control information and the user's exercise amount.

In the highland training room according to the present invention, the control information is information for learning in advance an amount of exercise obtained by the user while exercising in a sports room, and an amount of exhaust gas of the exhaust pump and an opening degree of the opening degree adjusting valve controlled by the control unit while the user is exercising in the sports room.

According to the above configuration, the amount of exhaust gas of the exhaust pump and the opening degree of the opening degree adjusting valve, which are set in accordance with the amount of motion of the user when actually moving in the exercise room, are learned and used as the control information. Thus, the control information includes the appropriate exhaust gas amount of the exhaust pump and the opening degree of the opening degree adjusting valve, which are set in accordance with the motion amount. Thus, the control unit can set a more appropriate ventilation condition according to the amount of exercise of the user.

The highland training cabin according to the present invention is further characterized by comprising: a learning unit configured to learn an exhaust amount of the exhaust pump and an opening degree of the opening degree adjusting valve, which are controlled by the control unit in accordance with an amount of exercise of the user, and store a result of the learning in the storage unit as the control information.

According to the above configuration, although the ventilation condition is temporarily set based on the control information and the user's exercise amount, when a new ventilation condition is set from the viewpoint that the gas composition in the exercise room constitutes a preset ratio or from the viewpoint that the indoor pressure is controlled within a preset negative pressure range, the control information can be updated by adding the new ventilation condition to the control information. By this update, when the control unit subsequently sets the ventilation condition, a more appropriate ventilation condition can be set. In addition, the physical ability change of the user accompanying the training can be tracked.

The highland training cabin according to the present invention is further characterized by comprising: and a notification unit that is provided in the exercise chamber and notifies the user of exercise information including one or more of information relating to the pressure in the chamber, information relating to the gas composition, and information relating to the amount of exhaust gas.

According to the above configuration, by including, for example, a display device such as a liquid crystal display screen or the like as the notification portion, it is possible to display the motion information or the like to notify the user. As the information on the indoor pressure or the information on the gas composition, there are listed, for example, information on a corresponding altitude, a video of an area (for example, a video of a plateau or a mountain) corresponding to the altitude, and the like, in addition to the value of the indoor pressure or the ratio of the gas composition, and the value of the oxygen concentration or the oxygen partial pressure. For example, the information on the amount of exhaust gas includes information on the amount of exhaust gas such as the amount of exercise, the amount of oxygen consumption, or the amount of energy consumption of the user.

The highland training compartment according to the present invention is further characterized in that the exercise device includes an exercise amount meter for measuring the amount of exercise of the user, and the exercise information includes information related to the amount of exercise.

According to the above configuration, the exercise information includes the amount of exercise measured by the exercise amount meter, and information such as the amount of oxygen consumption or energy consumption corresponding to the amount of exercise. Thus, the user can grasp the amount of exercise of the user while performing the highland training, and the convenience is high.

In order to achieve the above object, a method for controlling a highland training chamber according to the present invention comprises: an air discharging step of discharging air from a moving room, the inside of which can accommodate a user and a moving implement; an opening degree adjusting step of adjusting an opening degree of an opening degree adjusting valve that communicates the inside and the outside of the movement chamber; a pressure detection step of detecting an indoor pressure of the motion chamber; a gas detection step of detecting a gas composition of the motion chamber; a negative pressure control step of controlling the indoor pressure within a preset negative pressure range; a gas composition control step of controlling the gas composition detected in the gas detection step to constitute a preset ratio, the gas composition control step adjusting an amount of exhaust gas in the exhaust step and an opening degree in the opening degree adjustment step.

According to the above configuration, the same operational effects as those of the highland training chamber can be obtained.

Detailed Description

A highland training room according to an embodiment of the present invention will be described with reference to fig. 1 to 11.

[ first embodiment ]

[ brief description ]

Fig. 1 shows an overall structure of a cabin 100 (an example of a highland training cabin) according to the present embodiment. The capsule 100 comprises: a main body container 2, a motion chamber S is formed inside the main body container 2; a pump 3 (an example of an exhaust pump) for exhausting air from the moving chamber S; an automatic valve 4 (an example of an opening degree adjustment valve) 4 capable of adjusting an opening degree for communicating the inside of the motion chamber S with the outside; a pressure gauge 5 (an example of a pressure sensor), the pressure gauge 5 being for detecting the chamber internal pressure of the moving chamber S; a concentration meter 6 (an example of a gas sensor), the concentration meter 6 (an example of a gas sensor) detecting a carbon dioxide concentration (an example of a gas composition) of the indoor air of the moving chamber S; a treadmill 7 (an example of an exercise machine), the treadmill 7 being housed in the exercise compartment S; a control unit 1, the control unit 1 controlling the entire operation of the cabin 100; and a storage unit 9, in which information for controlling the operation of the cabin 100 by the control unit 1 is stored in the storage unit 9. The control unit 1 is communicably connected to the pump 3, the storage unit 9, and the like via an internal communication line N.

The user H enters the exercise room S through a position door (not shown) or the like provided in the main body case 2, and performs exercise such as running using the treadmill 7 in the exercise room S. At this time, the pump 3 depressurizes the motion chamber S to simulate an highland environment (hereinafter, sometimes referred to as a highland environment). The user H can efficiently improve the whole body endurance by exercising in the highland environment of the exercise room S.

[ Structure for respective portions ]

Based on fig. 1, various parts of the cabin 100 are explained. The body container 2 is the body of the capsule 100. The body container 2 has a movement chamber S formed therein and has airtightness to a degree sufficient to maintain the internal environment (the pressure or gas composition of the internal air) of the movement chamber S. The main body container 2 has a storage chamber (not shown) for storing the pump 3, the automatic valve 4, and a control circuit such as the control unit 1 or the storage unit 9, independently of the movement chamber S. The exercise room S accommodates a display screen 8 (an example of a notification unit) with a touch panel function in addition to the treadmill 7.

The display 8 is a notification device that operates by receiving an input of information such as an operation instruction from the user H and displaying a necessary notification to the user H. The display 8 receives an input of a motion menu desired by the user H (for example, in which highland environment the user moves) or identification information (for example, an ID number) of the user H, and transmits it to the control section 1. The display 8 displays various information (an example of notification) in accordance with an instruction from the control unit 1.

The treadmill 7 is an exercise device for the user H to run on a belt or the like running in a predetermined direction. The running machine 7 is connected with an exercise amount meter 70 for measuring the amount of exercise of the user H. The exercise amount meter 70 measures the amount of exercise of the user H based on the running distance of the user H (the running distance of the belt) and the personal information of the user H. The personal information of the user H is, for example, the sex or the weight of the user H. The sex or weight of the user H is stored in the storage unit 9 in association with, for example, the ID number. The motion amount meter 70 transmits information including the measured motion amount to the control section 1.

The pump 3 is an exhaust fan that exhausts the air from the moving chamber S to the outside (an example of an exhaust step) to thereby depressurize the moving chamber S. In the present embodiment, the pump 3 is a diaphragm vacuum pump. The pump 3 increases or decreases the amount of exhaust gas (amount of exhaust air) by increasing or decreasing the number of times the diaphragm valve is operated in the up-down (opening/closing) operation per unit time, thereby increasing or decreasing the degree of vacuum of the internal air of the motion chamber S. Hereinafter, the case of increasing the vacuum degree of the motion chamber S is referred to as decompression, and the case of decreasing the vacuum degree (pressure increase) of the internal air of the motion chamber S is referred to as opening. The pump 3 arbitrarily increases or decreases the displacement in accordance with a command from the control unit 1. Hereinafter, the case of increasing the number of times of up and down operations of the diaphragm valve of the pump 3 will be simply described as increasing the output. The case where the number of times of up and down operations of the diaphragm valve of the pump 3 is reduced is simply described as reducing the output.

The automatic valve 4 is a valve device that adjusts the opening degree to adjust the inflow amount of the outside air flowing into the movement chamber S. The automatic valve 4 is mounted on an exhaust pipe or the like for communicating the moving chamber S with the outside. In the present embodiment, the automatic valve 4 is a proportional valve whose opening degree can be adjusted in a range from full close to full open without a step in response to a command from the control unit 1. In a state where the pump 3 is operated, the automatic valve 4 increases or decreases the opening degree to increase or decrease the amount of air flowing from the outside (an example of the opening degree adjusting step), thereby opening or depressurizing the motion chamber S. When the opening degree of the automatic valve 4 is out of the full close state in a state where the pump S is stopped, the motion chamber S is opened.

The ventilation amount and the internal pressure (negative pressure range) of the motion chamber S are determined by the control unit 1 adjusting the exhaust amount of the pump 3 and the opening degree of the automatic valve 4 (an example of the negative pressure control step). The ventilation amount is the amount of outside air supplied to the movement chamber S per unit time. In the present embodiment, the ventilation volume and the exhaust volume are substantially the same when the internal pressure is constant.

When the exhaust gas amount of the pump 3 is relatively larger than the supply amount based on the opening degree of the automatic valve 4, the internal pressure (oxygen partial pressure) of the motion chamber S is maintained low. Thereby, the oxygen partial pressure becomes low. When the displacement of the pump 3 is relatively smaller than the supply amount based on the opening degree of the automatic valve 4, the internal pressure of the moving chamber S increases. Thereby, a high oxygen partial pressure is maintained. When both the exhaust amount of the pump 3 and the supply amount based on the opening degree of the automatic valve 4 are large, the ventilation amount of the sport chamber S is maintained in a large state. This maintains the oxygen supply amount from the outside to be large. When both the exhaust amount of the pump 3 and the supply amount based on the opening degree of the automatic valve 4 are small, the ventilation amount of the sport chamber S is maintained in a small state. This maintains the oxygen supply amount from the outside to be small. When the user H moves in the movement chamber S, oxygen in the movement chamber S is consumed and carbon dioxide is discharged into the movement chamber S. Thus, the control unit 1 adjusts the ventilation amount in accordance with the exercise amount of the user H, that is, the oxygen consumption amount, so that the gas composition in the exercise chamber S is maintained at a desired value.

Hereinafter, the conditions including the displacement of the pump 3 and the opening degree of the automatic valve 4 will be described as ventilation conditions. Further, the adjustment of the conditions including the adjustment of the displacement of the pump 3 and the adjustment of the opening degree of the automatic valve 4 is described as the adjustment of the ventilation conditions. In the present embodiment, the internal pressure or the oxygen partial pressure of the exercise chamber S is reduced or increased by adjusting the ventilation conditions as described above.

The pressure gauge 5 is a sensor for detecting the pressure (hereinafter, referred to as an internal pressure) of the internal air of the movement chamber S (an example of the pressure detection step). The pressure gauge 5 transmits information including the detected internal pressure to the control unit 1. As the pressure gauge 5, for example, a diaphragm type pressure gauge can be used.

The concentration meter 6 is a sensor that detects information (an example of a gas detection step) including a concentration (an example of a ratio, hereinafter referred to as a carbon dioxide concentration) of carbon dioxide in the internal air of the movement chamber S. The pressure gauge 5 transmits information including the detected carbon dioxide concentration to the control unit 1. For example, a carbon dioxide gas concentration meter using a dispersion-type infrared absorption method can be used as the concentration meter 6. In the present embodiment, the control unit 1 calculates the carbon dioxide concentration related to the gas composition such as the oxygen partial pressure or the carbon dioxide partial pressure of the exercise chamber S based on the information including the carbon dioxide concentration acquired from the concentration meter 6 and the information including the internal pressure acquired from the pressure gauge 5. Hereinafter, the information including the internal pressure obtained from the pressure gauge 5 is simply described as the internal pressure. Similarly, information including the carbon dioxide concentration is also described as the carbon dioxide concentration.

The storage unit 9 is a storage device capable of storing a software program for the control unit 1 to control the operation of the pod 100, and various information for the control unit 1 to control the operation of the pod 100. The storage unit 9 is constructed with a control information DB91, a pressure target information DB 92, a composition target information DB 93, and an image information DB 99 as a database for storing various kinds of information.

In the control information DB91, information for adjusting the ventilation condition according to the amount of exercise of the user H is stored. In the present embodiment, as shown in fig. 2, information (hereinafter referred to as exercise ventilation information) relating the exercise amount of the user H to the ventilation amount required according to the exercise amount of the user H is stored. The oxygen consumption of the user H increases as the exercise amount of the user H increases. Therefore, as listed in fig. 2, the exercise ventilation information has a correlation in which the ventilation amount increases as the amount of exercise of the user H increases.

When the user H moves in the exercise chamber S, the exercise ventilation information of the control information DB91 is stored for each internal pressure. The associated information is as follows: the learning is performed by acquiring and storing the amount of exercise acquired by the exercise amount meter 70 when the user H moves in the exercise chamber S and the ventilation conditions (particularly, the ventilation amount) controlled by the control unit 1 when the user H moves in the exercise chamber S, in association with a plurality of internal pressures of the user H when the user H moves in the exercise chamber S.

The control target value of the internal pressure is stored in the pressure target information DB 92. In the present embodiment, as shown in fig. 3, a control target value of the internal pressure (hereinafter referred to as an internal pressure target) corresponding to a motion menu desired by the user H is stored. The internal pressure target shown in fig. 3 is a list of a case where the simulated user H runs in the high ground, causing a change in altitude (height) by the movement accompanying the running. The internal pressure target is planned to pulsate the internal pressure vertically in accordance with the amount of exercise (in other words, exercise time) of the user H, and to control the internal pressure to pulsate in accordance with the internal pressure target. Fig. 3 shows the following example: the internal pressure X1 corresponding to the case of a relatively low altitude is reduced as an internal pressure target, and thereafter, the internal pressure X2 corresponding to the case of a relatively high altitude is further reduced to an internal pressure X2, and thereafter, the internal pressure X2 is opened to reach an internal pressure X3, and the internal pressure X3 corresponding to the altitude between the case of the internal pressure X1 and the case of the internal pressure X2. Further, X1 is the highest and X2 is the lowest as to the absolute value of the internal pressure.

The composition target information DB 93 stores a control range of the carbon dioxide concentration (hereinafter referred to as composition target information). In the present embodiment, a target value of the carbon dioxide concentration (hereinafter referred to as a concentration target) is stored as a control range of the carbon dioxide concentration.

The image information displayed by the display screen 8 is stored in the image information DB 99. In the present embodiment, a plurality of images such as still images and moving images corresponding to the internal pressure of the moving chamber S are stored as image information. For example, the image is a photograph or a moving image of a landscape that can be confirmed when walking along a running route on a high ground at an altitude corresponding to the internal pressure.

The control unit 1 is a central control device of the cabin 100. The control unit 1 includes a ventilation control unit 11, a pressure determination unit 12, a composition determination unit 13, a movement amount determination unit 14, a ventilation amount determination unit 15, a notification control unit 16, and a learning unit 19 as functional units realized by software programs stored in the storage unit 9. The functions of the functional units such as the ventilation control unit 1 will be described together with the flow of the operation control of the cabin 100 by the control unit 1.

[ flow of control action ]

Fig. 4 illustrates a flow of operation control of the pod 100 by the control unit 1. When the user H enters the exercise room S and instructs the start of training from the display 8, the ventilation control unit 11 executes the pressure control step (# 401): the pump 3 is operated at a preset exhaust gas amount and the opening degree of the automatic valve 4 is adjusted based on the exercise ventilation information of the control information DB91, the internal pressure target of the pressure target information DB 92, the internal pressure detected by the pressure gauge 5, and the exercise amount of the user H acquired by the exercise amount meter 70. Details of the pressure control step (#401) will be described later.

After that, the notification control unit 16 reads an image corresponding to the internal pressure detected by the pressure gauge 5 with reference to the image information DB 99, and displays the corresponding image on the display 8 (# 402). According to the image displayed on the display screen 8, the user H can enjoy training with pleasure while perceiving the presence. At this time, the notification control unit 16 may display information on the internal pressure detected by the pressure gauge 5 and information on the amount of exercise of the user H acquired by the amount of exercise meter 70 as exercise information on the display 8 so as to be superimposed on an image displayed on the display 8. By such display, the user H can grasp the amount of exercise of the user H in real time and can perform training appropriately and safely.

Then, the ventilation control unit 11 performs a ventilation amount adjustment control step (an example of a gas composition control step) (# 403): the ventilation amount is adjusted based on the composition target information of the composition target information DB 93, the exercise amount of the user H acquired by the exercise amount meter 70, and the carbon dioxide concentration acquired by the concentration meter 6. The details of the ventilation amount adjustment control step (#403) will be described later.

After that, the learning portion 19 executes a learning step under a preset condition (# 404): the current ventilation amount is stored in the control information DB91 in accordance with the exercise amount of the user H. Details of the learning step (#404) will be described later.

After that, when some end condition such as the user H instructing the end of exercise from the display 8 or the elapse of exercise time set by a timer or the like is satisfied (yes in # 405), the control unit 1 proceeds to the opening control step #406 to return the exercise chamber S to the atmospheric pressure and ends the operation. If the control unit 1 does not satisfy the termination condition (no in # 405), the process returns to the pressure control step (# 401). In the opening control step (#406), the preset amount of opening of the automatic valve 4 and the internal pressure holding are repeatedly performed, and the internal pressure is increased to the atmospheric pressure step by step until the internal pressure of the motion chamber S becomes equal to the atmospheric pressure. Hereinafter, the control operation including #401 to #405 will be described as "unit control".

The flow of actions of the pressure control step is illustrated in fig. 5. In the pressure control step, first, the pressure determination unit 12 acquires the internal pressure target of the pressure target information DB 92 (# 501). In this case, in the present embodiment, the pressure determination unit 12 sets an upper limit internal pressure (for example, a value obtained by adding 7% to the internal pressure target) and a lower limit internal pressure (a value obtained by subtracting 7% from the internal pressure target) corresponding to the internal pressure target.

After that, the ventilation control unit 11 refers to the exercise ventilation information in the control information DB91 to determine the ventilation amount (# 502). In the present embodiment, the ventilation amount is set in accordance with the exercise amount of the user H acquired by the exercise amount meter 70 and the internal pressure determined as the internal pressure target of the exercise chamber S.

Further, the pressure determination unit 12 determines whether or not the internal pressure is higher than the upper limit of the internal pressure (#503), and if the internal pressure is higher than the upper limit of the internal pressure (#503 yes), the ventilation control unit 11 controls to reduce the pressure by a preset amount (for example, 5kPa) (#505) and ends. For example, as control for depressurizing only a preset amount, the opening degree of the automatic valve 4 is reduced by a preset amount while the output of the pump 3 is increased to maintain the ventilation amount. If the internal pressure is equal to or lower than the upper internal pressure limit (#503, no), it is determined whether the internal pressure is lower than the lower internal pressure limit (# 504). When the internal pressure is lower than the lower limit of the internal pressure (#504 yes), the ventilation control unit 11 controls to open only a preset amount (for example, 5kPa) (#506), and ends. For example, as the control of opening only by a preset amount, the opening degree of the automatic valve 4 is opened by a preset amount while the output of the pump 3 is reduced to maintain the ventilation amount. If the internal pressure is not lower than the lower internal pressure limit (#504 no), the process ends immediately.

The flow of the ventilation control step is illustrated in fig. 6. In the ventilation amount adjustment control step, the composition determination portion 13 determines the concentration target by acquiring the composition target information of the composition target information DB 93 (# 601). The composition determination unit 13 determines whether or not the carbon dioxide concentration is higher than the concentration target (#602), and if the carbon dioxide concentration is higher than the concentration target (#602 yes), the ventilation control unit 11 controls to increase the ventilation amount by a predetermined amount (#606), and ends.

If the carbon dioxide concentration is equal to or less than the concentration target (# no of 602), it is determined whether or not the carbon dioxide concentration is lower than the concentration target (#603), and if the carbon dioxide concentration is lower than the concentration target (#603), the routine proceeds to # 605. In the case where the carbon dioxide concentration is equal to the concentration target (# no of 603), the routine proceeds to # 604.

In #604 and #605, the exercise amount determination unit 14 determines whether or not the exercise amount of the user H has increased or decreased from the time of the previous unit control. In #604, the exercise amount determination unit 14 compares the exercise amount of the user H (hereinafter referred to as the present exercise amount) acquired by the exercise amount meter 70 with the exercise amount of the user H (hereinafter referred to as the previous exercise amount) at the time of the previous unit control stored in the storage unit 9, and when the present exercise amount increases from the previous exercise amount (#604 yes), the ventilation control unit 11 predicts an increase in oxygen consumption due to the increase in the exercise amount of the user H, increases the ventilation amount by a preset amount only (#606), and stores the current ventilation amount and the present exercise amount in the storage unit 9 (#608), and ends. By controlling to predict the increase in oxygen consumption, it is possible to avoid the exposure of the user H to the dangerous oxygen deficient environment due to inattention, and thus to improve the safety of the training. If the present motion amount is equal to or less than the previous motion amount (# no in 604), the routine proceeds to # 605. Further, for example, as control for increasing only the ventilation amount by a preset amount, the output of the pump 3 is increased while the opening degree of the automatic valve 4 is opened by a preset amount to maintain the internal pressure.

When the present exercise amount is lower than the previous exercise amount (#605 yes), the ventilation control unit 11 predicts a decrease in oxygen consumption due to a decrease in the exercise amount of the user H, decreases the ventilation amount by a preset amount (#607), stores the current ventilation amount and the present exercise amount in the storage unit 9 (#608), and ends the routine. By controlling the prediction of the reduction in oxygen consumption, excessive ventilation can be suppressed and energy saving can be achieved. When the present exercise amount is equal to the previous exercise amount (# no in 605), the current ventilation amount and the present exercise amount are stored in the storage unit 9 (#608), and the process ends. Further, for example, as control for reducing the ventilation amount by only a preset amount, the output of the pump 3 is reduced while the opening degree of the automatic valve 4 is reduced by a preset amount to maintain the internal pressure.

In addition, in #604 and #605, when the previous exercise amount was not stored in the storage unit 9, the exercise amount determination unit 14 determines that the present exercise amount is not increased or decreased from the previous exercise amount.

The flow of actions of the learning step is illustrated in fig. 7. When the exercise amount determination unit 14 determines that the exercise amount is not increased or decreased from the previous exercise amount and the exercise amount is not changed (# no of 701), and the ventilation amount determination unit 15 determines that the ventilation amount at the time of the previous unit control (hereinafter referred to as the previous ventilation amount) stored in the storage unit 9 is changed from the current ventilation amount (yes of # 702), the learning unit 19 determines that the ventilation amount is inconsistent with respect to the oxygen consumption amount of the user H who performs the preset exercise for the preset period, and the learning unit 19 stores the current ventilation amount in the control information DB91 in correspondence with the current internal pressure and the current exercise amount to perform learning. Through this learning, the exercise ventilation information of the control information DB91 keeps the oxygen concentration or the carbon dioxide concentration in the exercise room within an appropriate range at a specific internal pressure, and at the same time, the exercise ventilation information of the control information DB91 is updated to information that more closely matches the latest physical condition (e.g., growth or aging, change in physical fitness due to training accumulation) of the user H. In the present embodiment, the ventilation amount is stored in the control information DB91 instead of the number of times the diaphragm valve is operated up and down per unit time (information corresponding to the amount of exhaust gas) and the opening degree of the automatic valve 4.

When the exercise amount determination unit 14 determines that the exercise amount has changed due to the increase or decrease of the present exercise amount from the previous exercise amount (# yes in 701), the fitness of the ventilation amount cannot be determined and the exercise amount determination unit ends immediately. When the exercise amount determination unit 14 determines that the exercise amount of this time is not increasing or decreasing from the previous exercise amount and the exercise amount is not changing (# no in 701), and the ventilation amount determination unit 15 determines that the current ventilation amount is not changing from the previous ventilation amount (# no in 702), the current control is immediately ended as appropriate.

[ control of internal pressure ]

Fig. 8 is a graph showing pressure changes when the internal pressure of the motion chamber S is reduced from the atmospheric pressure to the target internal pressure and then released to the atmospheric pressure again. As described above, in the pressure control step, when the internal pressure is reduced, the ventilation control unit 11 is controlled to reduce the internal pressure by the preset amount (#505 in fig. 5). Therefore, the internal pressure is reduced in stages (stepwise) in the process of reducing the internal pressure. This avoids a physical impairment (e.g. tinnitus or a so-called "riding headache") of the user H as a result of a sudden pressure drop.

As described above, in the pressure control step, when the internal pressure is released, the ventilation control unit 11 performs control (#506 in fig. 5) to release only the automatic valve 4 by a predetermined amount. In the opening control step (#406 in fig. 4), the case where the preset amount of opening of the automatic valve 4 and the internal pressure holding are repeatedly executed until the internal pressure of the motion chamber S becomes equal to the atmospheric pressure has been described. Therefore, the internal pressure is increased in stages (stepwise) in the process of opening the internal pressure. This prevents the user H from experiencing a physical condition failure, as in the process of reducing the internal pressure.

Fig. 9 is a graph showing the pressure change pattern over time of the internal pressure corresponding to the case where the internal pressure target is planned to pulsate as shown in fig. 3. The time points of the motion amounts a2, B2, C2 in fig. 3 correspond to the elapsed times a9, B9, C9 in fig. 9. In the case of fig. 9, the internal pressure needs to be changed (reduced) relatively greatly in the process of first reducing the pressure to the internal pressure X1 or in the process of continuously reducing the pressure from the internal pressure X1 to the internal pressure X2 after the time point of time a9, and therefore the internal pressure is reduced stepwise. Further, in the process of opening from the internal pressure X2 to the internal pressure X3 after the time point of the time B9 elapses, or in the process of reducing again from the internal pressure X3 to the internal pressure X2 after the time point of the time C9 elapses, the amount of change in the internal pressure is small, and therefore, the opening or the reduction is continuously performed.

[ second embodiment ]

In the first embodiment, the case where the cabin 100 has the movement amount meter 70 and the control unit 1 controls the ventilation amount based on the movement amount acquired by the movement amount meter 70 has been described, but the second embodiment has the following differences: the cabin 100 does not have the exercise amount meter 70 and performs control without using the exercise amount of the user H that can be obtained from the exercise amount meter 70 in the first embodiment. Hereinafter, only the configuration different from the first embodiment will be described, and the same configuration as the first embodiment will not be described.

The control information DB91 stores, in place of the exercise ventilation information in the first embodiment, initial values of ventilation conditions for the respective internal pressures of the exercise chambers S.

In the composition target information of the composition target information DB 93, in addition to the concentration target in the first embodiment, a control lower limit value (hereinafter, referred to as a lower limit concentration) in a control range in which the carbon dioxide concentration is lower than the concentration target is stored as the control range of the carbon dioxide concentration.

In the ventilation amount adjustment control step, operations in place of the ventilation amount adjustment control step shown in fig. 6 in the first embodiment are performed by omitting #604 and #605 and replacing #603 and #608 with #1003 and #1008, respectively, as shown in fig. 10. In addition, the remaining steps shown in fig. 10 are the same as those shown in fig. 6.

In #1003, the composition determining unit 13 determines whether or not the carbon dioxide concentration is lower than the lower limit concentration, and if the carbon dioxide concentration is lower than the lower limit concentration (yes in #1003), the routine proceeds to # 607. If the carbon dioxide concentration is not less than the lower limit concentration (#1003, no), the routine proceeds to # 1008. The composition determining section 13 determines whether or not the carbon dioxide concentration is higher than the concentration target (#602), and determines whether or not the carbon dioxide concentration is lower than the lower limit concentration (#1003), and as shown in fig. 11, the carbon dioxide concentration in the moving room S is controlled more effectively by setting the lower limit concentration or higher and the target concentration or lower as the control target.

#1008 stores the current ventilation amount in the storage unit 9.

The learning step is performed by omitting #701 of fig. 7 in the first embodiment. The rest is the same.

In the second embodiment described above, it is possible to realize control without using the amount of exercise of the user H acquired by the exercise amount meter 70 while maintaining the exercise room S in an appropriate highland environment. Therefore, unlike the running machine 7, in the case where the user H performs exercise using other exercise equipments (e.g., dumbbells) as they do not use or cannot connect the exercise amount meter 70, the user H can also perform appropriate high-level training in the exercise room S.

As described above, a small and low-cost high-rise training cabin can be provided.

[ other embodiments ]

(1) In the above embodiment, the diaphragm vacuum pump is used as the pump 3, but the pump 3 is not limited thereto. As the pump 3, a piston type or rotary type pump, a fan or jet type exhaust fan, a cleaner, or the like may be used.

(2) In the above-described embodiment, the concentration meter 6 as an example of the gas sensor is exemplified by a carbon dioxide gas concentration meter using a dispersion type infrared absorption method using information including a carbon dioxide concentration, but the concentration meter 6 is not limited thereto, and a sensor that detects a carbon dioxide partial pressure or another parameter related to a carbon dioxide concentration may be used.

(3) In the above-described embodiment, the case where the concentration meter 6 that detects information including the carbon dioxide concentration is used as an example of the gas sensor is described, but instead of the concentration meter 6 used, an oxygen concentration meter, a sensor that detects the oxygen partial pressure, or another parameter related to the oxygen partial pressure or the oxygen concentration may be used as the gas sensor.

(4) In the above embodiment, the control range of the carbon dioxide concentration is stored in the composition target information DB 93, and in the present embodiment, a case where the target value of the carbon dioxide concentration is stored as the control range of the carbon dioxide concentration has been described. However, the control range of the oxygen concentration or the oxygen partial pressure may be stored in the composition target information DB 93. In this case, a target value of the oxygen concentration or a target value of the oxygen partial pressure may be stored in the composition target information DB 93 as the control range of the oxygen concentration or the oxygen partial pressure.

(5) In the second embodiment described above, the density target and the lower limit density are stored in the composition target information of the composition target information DB 93, and #1003 illustrated in fig. 10 illustrates the following case: the composition determining section 13 determines whether or not the carbon dioxide concentration is lower than the lower limit concentration, and if the carbon dioxide concentration is lower than the lower limit concentration (yes in #1003), the routine proceeds to # 607. However, the lower limit density is not necessarily stored in the composition target information of the composition target information DB 93.

In this case, #1003 may be replaced with a lower limit concentration, for example, as a concentration target. In addition, the composition judging section 13 judges whether or not the carbon dioxide concentration is lower than the concentration target, and in the case where the carbon dioxide concentration is lower than the concentration target, it shifts to # 607. Otherwise, transition is made to #1008 where the carbon dioxide concentration is equal to the concentration target.

(6) In the first embodiment, the case where the control unit 1 of the nacelle 100 includes the learning unit 19 has been described, but the control unit 1 may not include the learning unit 19. In this case, #404 is omitted in the operation control flow of the pod 100 by the control unit 1 shown in fig. 4.

(7) In the first embodiment, the following information is stored in the control information DB 91: the learning is performed by acquiring and storing information, which is constructed in advance, by the amount of movement acquired by the movement amount meter 70 when the user H moves in the exercise chamber S and the ventilation condition (particularly, the ventilation amount) controlled by the control unit 1 when the user H moves in the exercise chamber S, in association with a plurality of internal pressures of the user H when the user H moves in the exercise chamber S. However, the information for adjusting the ventilation condition stored in the control information DB91 is not limited to the information constructed by the above-described learning.

The configurations disclosed in the above embodiments (including other embodiments, and the same below) may be combined with the configurations disclosed in the other embodiments and applied to the range where no contradiction occurs, and the embodiments disclosed in the present specification are given as examples, and the embodiments of the present invention are not limited thereto, and may be appropriately changed within a range where the object of the present invention is not departed.
