Further, when the solenoid valve 11 is brought into the (b) open state by the control of the controller 15, the pressure on the seat 114 is released and the vicinity of the center of the diaphragm 112 is lifted. As a result, the gas filled in the high-pressure gas container 10 flows out through the manual valve 12 .

As for the manual valve 12 as well, the diaphragm 122 is controlled in a similar manner by operating the handle 121 .

The position measurement unit 21 measures the position of the mobile device 20 . Specifically, the position measurement unit 21 receives wireless communication transmitted from GPS satellites and acquires position data of the mobile device 20 .

Note that the position measuring unit 21 may acquire the position data of the mobile device 20 by a method other than GPS. For example, the position measurement unit 21 may estimate the position of the mobile device 20 from the position data of the base station by performing wireless communication with the base station. The position measurement unit 21 may also estimate the position of the mobile device 20 by appropriately combining position data obtained from GPS satellites and position data obtained from base stations.

In addition, the position measuring unit 21 measures velocity, acceleration, etc., estimates the position of the mobile device 20 by estimating the self-position based on the initial position given in advance and the measured velocity, acceleration, etc. Also good.

The determination unit 22 determines whether the electromagnetic valve 11 is open or closed based on the position measured by the position measurement unit 21 and the usable range data 25 .

The short-range communication unit 23 performs short-range communication with the high-pressure gas container 10 . Specifically, the short-range communication unit 23 transmits to the high-pressure gas container 10 control data indicating the control content for the open/closed state determined by the determination unit 22 .

The storage unit 24 stores various data necessary for determination by the determination unit 22 . Specifically, the storage unit 24 stores usable range data 25 .

The usable range data 25 is data indicating a reference range set as a usable range of gas. Specifically, the usable range data 25 is data indicating the range of positions where the high-pressure gas can be used. For example, the usable range data 25 may be data indicating usable positions by the range of latitude and longitude.

Next, operations of the control system 1 will be described with reference to the drawings.

FIG. 8 is a flow chart showing an example of control processing of the solenoid valve according to the first embodiment.

When the short-range communication unit 23 approaches the high-pressure gas container 10 and starts communication, the portable device 20 executes control processing of the solenoid valve.

The position measurement unit 21 acquires position data indicating the position of the mobile device 20 (step S11). Specifically, position measurement unit 21 measures the position of portable device 20 by GPS receiver 205 receiving GPS signals from GPS satellites.

Here, the GPS receiver 205 may measure the position periodically, for example, every 10 seconds. Also good.

If the GPS receiver 205 measures the position every 10 seconds, for example, the position of the portable device 20 may be the average value of the longitude, latitude, etc. included in the plurality of measured position data.

Next, the determination unit 22 determines whether or not the position data has been acquired (step S12). When determining that the position data could not be obtained (step S12: No), the determination unit 22 terminates the process.

Further, when determining that the position data has been acquired (step S12: Yes), the determination unit 22 further determines whether or not the position of the mobile device 20 is within the usable range (step S13).

Specifically, the determination unit 22 acquires the usable range data 25 stored in the storage unit 24 and determines whether the position of the mobile device 20 exists within the range defined by the usable range data 25 . determine whether

For example, if the range specified in the usable range data 25 is 122 degrees to 154 degrees east longitude and 20 degrees to 46 degrees north latitude, if the position of the portable device 20 is 134 degrees east longitude and 40 degrees north latitude, , the determination unit 22 determines that the position of the mobile device 20 is within the usable range.

Further, when the position of the mobile device 20 is 114 degrees east longitude and 50 degrees north latitude, the determination unit 22 determines that the position of the mobile device 20 is not within the usable range.

Here, the usable range data 25 may be, for example, a combination of a plurality of ranges, or may include a specification for excluding a specific range from the usable range.

If the determining unit 22 determines that the position of the mobile device 20 is not within the usable range (step S13: No), the process ends.

Further, when the determination unit 22 determines that the position of the portable device 20 is within the usable range (step S13: Yes), the short-range communication unit 23 transmits control data indicating control details for opening the solenoid valve 11. (Step S14).

When the short-range communication device 14 of the high-pressure gas container 10 receives the control data, the controller 15 transmits an opening signal to the solenoid valve 11 to cause the actuator 111 to generate an electromagnetic force, causing the diaphragm 112 to move toward the seat 114. release the pressure. Thereby, the gas inside the high-pressure gas container 10 passes through the body 113 and reaches the manual valve 12 .

After that, when the manual valve 12 is opened by the user's operation, the gas that has reached the manual valve 12 flows out from the injection port.

According to the control system 1 according to the present embodiment, when the portable device 20 is within the usable range, the gas flows out by operating the manual valve 12, whereas when the portable device 20 is out of the usable range , even if the manual valve 12 is operated, the gas does not flow out because the solenoid valve 11 is closed.

Further, when the portable device 20 and the high pressure gas container 10 start short-distance communication, the control process described above is executed. can be used. Therefore, the places where the high pressure gas is used can be restricted within the usable range.

Specifically, when the high-pressure gas container 10 according to the present embodiment is filled with high-pressure gas and sold, the usable range data 25 representing the place to be used as the sales destination is generated and stored in the storage unit 24 of the portable device 20. , and hand over the portable device 20 to the customer of the sales destination.

A customer who has purchased the high pressure gas at the shipping destination of the high pressure gas container 10 can use the high pressure gas by causing the portable device 20 to communicate with the high pressure gas container 10 at a location where the high pressure gas can be used. At this time, even if the mobile device 20 is brought into short-range communication with the high-pressure gas container 10 at an unusable location, the solenoid valve 11 does not open, so the high-pressure gas cannot be used.

In this way, when the high pressure gas is sold, it is possible to limit the places where the high pressure gas is used within the usable range.

The high-pressure gas container 10 according to this embodiment may include a plurality of combinations of the solenoid valves 11 and the manual valves 12 . In that case, the controller 15 controls to open all the solenoid valves 11 when opening the solenoid valves 11 . As a result, even if one of the plurality of solenoid valves 11 fails to open due to a problem, the other solenoid valve 11 can be used as a substitute.

(Second embodiment)
A second embodiment will be described below with reference to the drawings. The second embodiment differs from the first embodiment in that the electromagnetic valve 11 is controlled so as not to open when the manual valve 12 is in the open state. In the following description of the second embodiment, differences from the first embodiment will be described, and those having the same functional configuration as in the first embodiment will have the same functions as in the first embodiment. The same reference numerals as the reference numerals are given, and the description thereof is omitted.

The high-pressure gas container 10 according to this embodiment further includes an open/close sensor 18 . The open/close sensor 18 is a device that measures the open/close state of the manual valve 12 .

FIG. 9 is a diagram showing an example of the hardware configuration of an electric system according to the second embodiment.

The open/close sensor 18 is connected to the battery 13 by an electric wire. In addition, the open/close sensor 18 is connected to the controller 15 so as to be communicable.

The open/close sensor 18 receives power from the battery 13 and measures the open/close state of the manual valve 12 . The open/close sensor 18 then transmits the measurement results to the controller 15 . Specifically, the opening/closing sensor 18 periodically, for example, every 10 seconds, transmits opening/closing data indicating the opening/closing state of the manual valve to the controller 15 .

FIG. 10 is a flow chart showing an example of control processing of the solenoid valve according to the second embodiment.

The controller 15 receives control data indicating details of control for opening the electromagnetic valve 11 via the short-range communication device 14 (step S21).

Next, the controller 15 acquires opening/closing data of the manual valve 12 via the opening/closing sensor 18 (step S22). Specifically, when the opening/closing data is transmitted, for example, every 10 seconds, the controller 15 acquires the latest opening/closing data.

Subsequently, the controller 15 determines whether or not the manual valve 12 is closed (step S23). When the controller 15 determines that the manual valve 12 is not closed (step S23: No), the process ends.

Further, when the controller 15 determines that the manual valve 12 is closed (step S23: Yes), the controller 15 opens the solenoid valve 11 (step S24).

According to the control system 1 of this embodiment, when the manual valve 12 is open, the electromagnetic valve 11 does not open even if the portable device 20 is within the usable range. As a result, it is possible to avoid a situation in which the electromagnetic valve 11 is opened by mistake while the manual valve 12 is open, causing gas to flow out at a timing unexpected by the user.

Further, when the portable device 20 is within the usable range, the solenoid valve 11 is opened when the manual valve 12 is changed from the open state to the closed state by the user's operation. This allows the user to use gas within the usable range by closing and reopening the manual valve 12 even when the manual valve 12 is accidentally opened.

(Third embodiment)
A third embodiment will be described below with reference to the drawings. The third embodiment differs from the first embodiment in that a manually operated solenoid valve is provided instead of the solenoid valve 11 and the manual valve 12 . In the following description of the third embodiment, differences from the first embodiment will be described, and those having the same functional configuration as in the first embodiment will have the same functions as in the first embodiment. The same reference numerals as the reference numerals are given, and the description thereof is omitted.

A high-pressure gas container 10 according to this embodiment includes a manually operated solenoid valve 19 instead of the solenoid valve 11 and the manual valve 12 .

FIG. 11 is a diagram showing an example of a manually operated solenoid valve according to the third embodiment.

The manually operated solenoid valve 19 is a manually operated solenoid valve. Specifically, the manually operated solenoid valve 19 includes a handle 191 , an actuator 192 , a diaphragm 193 and a body 194 .

The handle 191 controls pressing and releasing of the diaphragm 193 in response to user's operation.

The actuator 192 is a solenoid actuator or the like, in which a movable iron core is installed in the solenoid, and the movable iron core is moved up and down by an electromagnetic force generated by applying an electric current to control pressing and releasing of the diaphragm 193 .

The diaphragm 193 is a film made of metal such as Ni—Co alloy or PTFE (polytetrafluoroethylene), or resin. Diaphragm 193 is controlled to be depressed and released by handle 191 and actuator 192 to control the outflow of gas flowing to body 194 .

More specifically, diaphragm 193 receives pressure from both handle 191 and actuator 192 . Therefore, while either handle 191 or actuator 192 is pressing, diaphragm 193 is not released and gas does not flow out.

When both handle 191 and actuator 192 are released, diaphragm 193 is released and gas flows out.

Therefore, the manually operated electromagnetic valve 19 is opened by the user's operation of the handle 191 after the controller 15 has enabled the valve to be opened.

FIG. 12 is a diagram showing an example of the hardware configuration of an electric system according to the third embodiment.

A manually operated solenoid valve 19 is communicably connected to the controller 15 . Under the control of the controller 15, the manually operated electromagnetic valve 19 shifts from a state in which it cannot be opened to a state in which it can be opened by manual operation.

FIG. 13 is a flow chart showing an example of control processing for a manually operated solenoid valve according to the third embodiment.

Steps S31 to S33 of the control process for the manually operated solenoid valve 19 according to this embodiment are the same as steps S11 to S13 of the control process for the solenoid valve 11 according to the first embodiment.

When the determination unit 22 determines that the position of the portable device 20 is within the usable range (step S33: Yes), the short-range communication unit 23 transmits control data indicating the details of control for opening the manually operated solenoid valve 90. is transmitted (step S34).

When the short-range communication device 14 of the high-pressure gas container 10 receives the control data, the controller 15 transmits an opening signal to the manually operated solenoid valve 19 to generate an electromagnetic force in the actuator 192, causing the diaphragm 193 to move the actuator 192. release the pressure from

As a result, the diaphragm 193 receives only pressure from the handle 191 . That is, the manually operated solenoid valve 19 is brought into a state in which it can be opened by manual operation.

According to the high-pressure gas container 10 according to the present embodiment, gas flows out by operating the manually operated solenoid valve 90 within the usable range of the portable device 20, whereas outside the usable range of the portable device 20, Gas does not flow out even when the manually operated solenoid valve 90 is operated. Therefore, the places where the high pressure gas is used can be restricted within the usable range.

Also, the manually operated solenoid valve 90 is not opened unless it is manually operated. Therefore, for example, when the usable range is passed, gas does not flow out between the plurality of valves.

The manually operated solenoid valve 90 does not open even by manual operation unless the controller 15 enables it to be opened. Further, manual operation may not be possible, ie, the handle 191 may not be rotated unless it is operable by the controller 15 . In this way, the pressure applied to the diaphragm 193 by the handle 191 is not erroneously released outside the usable range.

(Fourth embodiment)
A fourth embodiment will be described below with reference to the drawings. The fourth embodiment differs from the first embodiment in that the solenoid valve 11 is controlled from the outside. In the following description of the fourth embodiment, differences from the first embodiment will be described, and for those having the same functional configuration as the first embodiment, the The same reference numerals as the reference numerals are given, and the description thereof is omitted.

Also, the wireless LAN access point 40 is communicably connected to the control device 30 via the network 50 .

The control device 30 determines the control details of the solenoid valve 11 based on the position data, and transmits a control signal indicating the determined control details to the high-pressure gas container 10 via the network 50 and the wireless LAN access point 40 .

The wireless LAN access point 40 is a communication relay device that sets up a wireless LAN and mediates communication between devices connected to the network 50 and the wireless device 100 .

FIG. 16 is a diagram showing an example of functions of a control device according to the fourth embodiment.

The control device 30 includes a storage section 31 , a position data acquisition section 32 , a determination section 33 and a valve control data transmission section 34 .

The storage unit 31 stores various data necessary for controlling the control device 30 . Specifically, the storage unit 31 stores usable range data 35 .

The usable range data 35 is data indicating a reference range set as a usable range of gas. Specifically, the usable range data 35 is data indicating the range of positions where the high-pressure gas can be used. For example, the usable range data 35 may be data indicating usable positions in terms of latitude and longitude.

The position data acquisition unit 32 acquires position data indicating the position of the portable device 20 via the wireless device 100 of the high pressure gas container 10 .

The determination unit 33 determines the open/close state of the solenoid valve 11 based on the position data acquired by the position data acquisition unit 32 and the usable range data 35 .

The valve control data transmission unit 34 transmits control data indicating control details for opening/closing control of the electromagnetic valve 11 to the high-pressure gas container 10 according to the determination result of the determination unit 33 .

The operation of the control device 30 according to this embodiment is the same as the control processing of the solenoid valve 11 according to the first embodiment. According to the control system 1 according to the present embodiment, as in the first embodiment, within the usable range, the gas flows out by operating the manual valve 12, but outside the usable range, the manual valve Even by the operation of 12, the gas does not flow out because the solenoid valve 11 is closed. Therefore, the places where the high pressure gas is used can be restricted within the usable range.

According to the control system 1 according to this embodiment, the control of the valves of the plurality of high-pressure gas containers 10 can be performed by one control device 30 . Therefore, the control device 3 performs maintenance such as creation and modification of a program that defines the processing contents of the usable range data 35 and the determination unit 33.
By doing so, the usable location can be set and changed without performing maintenance of the portable device 20 .

Also, the usable range data 35 may include an identifier for identifying the high-pressure gas container 10, and the usable range may differ for each identifier. In this way, the control device 30 can centrally manage the usable locations of the plurality of high-pressure gas containers 10 .

Furthermore, since the solenoid valve 11 is opened not only by the control by the mobile device 20 but also by the control by the control device 30, even if a device having the same functions as the mobile device 20 is illegally created, the processing content of the control device 30 will be changed. Unless analyzed, it is difficult to fraudulently open the solenoid valve 11 .

In this embodiment, an example is shown in which the portable device 20 transmits position data indicating the position measured by the portable device 20 to the high-pressure gas container 10, and the high-pressure gas container 10 transmits the received position data to the control device 30. Ta. However, even if the portable device 20 communicates with the wireless LAN access point 40 via the long-distance communication IF 206 and transmits the position data to the control device 30 without going through the high-pressure gas container 10. good.

In that case, the portable device 20 establishes communication with the wireless LAN access point 40 after establishing communication with the high-pressure gas container 10 by short-range communication, and wirelessly transmits the position data indicating the position measured by the position measurement unit 21. It may be transmitted to the control device 30 via the LAN access point 40 .

In each of the above-described embodiments, the high-pressure gas container 10 is equipped with various sensors, and in addition to the open/close sensor 18, depending on the measurement results of other sensors, the control contents of the solenoid valve 11 or the manually operated solenoid valve 19 are determined. can be

For example, the high-pressure gas container 10 may include a clock, a remaining gas sensor, a remaining battery sensor, a speed sensor, an acceleration sensor, and the like.

For example, a clock measures time. Then, the controller 15 receives the data indicating the details of the control in which the valve can be opened by manual operation based on the time acquired from the clock, and then the reference period indicating the time when the valve can be opened by manual operation has passed. Determine whether or not

Note that the reference period is preset in the controller 15 . When the controller 15 determines that the reference period has elapsed and acquires data indicating that the manual valve 12 is open from the open/close sensor 18 , it performs control to close the solenoid valve 11 .

In this way, if the manual valve 12 is left unopened after it becomes manually operable within the usable range, by closing the solenoid valve 11, for example, the expiration date can be set. It is possible to prevent erroneous operations related to

For example, a gas remaining amount sensor measures the remaining amount of high pressure gas. If the change in the remaining amount of gas obtained from the gas remaining amount sensor is not in a pattern set in advance, the controller 15 or the control device 30 turns the solenoid valve 11 on regardless of the states of the other sensors. Control to open or control to enable the manually operated solenoid valve 19 to be opened is not performed.

Alternatively, when the remaining amount of gas is decreasing at a rate equal to or higher than a preset threshold, the controller 15 or the control device 30 controls or manually operates the solenoid valve 11 to open regardless of the state of other sensors. No control is performed to enable the solenoid valve 19 to be opened.

By using a gas residual amount sensor together and controlling to open the solenoid valve 11 or to enable the manual operation electromagnetic valve 19 to be opened only when the change in the residual amount of gas satisfies the set conditions, the normal operation can be performed. Since it can be estimated that the use state is different from the use state of the device, an abnormal use state or the like can be prevented.

Also, the battery remaining amount sensor measures the remaining amount of the battery 13 . Then, when the remaining amount of the battery 13 is equal to or less than a preset threshold, the controller 15 or the control device 30 controls to open the solenoid valve 11 or activates the manually operated solenoid valve 19 regardless of the state of other sensors. Do not control to enable opening.

By using a battery residual amount sensor together and performing control to open the solenoid valve 11 or control to enable the opening of the manually operated electromagnetic valve 19 only when the residual amount of the battery 13 satisfies a preset condition, the battery It is possible to prevent the valve from being opened by mistake when the remaining amount of 13 is exhausted and each sensor does not operate.

Also, the speed sensor measures the speed of the high-pressure gas container 10 . The acceleration sensor measures acceleration of the high-pressure gas container 10 . When the velocity or acceleration of the high pressure gas container 10 is greater than or equal to a preset threshold, the controller 15 or control device 30 controls or manually operates the solenoid valve 19 to open the solenoid valve 11 regardless of the state of the other sensors. Do not control to enable opening.

Using a speed sensor or an acceleration sensor together, only when the speed or acceleration of the high-pressure gas container 10 satisfies the set conditions, control to open the solenoid valve 11 or control to enable the opening of the manually operated solenoid valve 19. Therefore, it is possible to prevent the valve from being accidentally opened during transportation of the high-pressure gas container 10 .

In each embodiment described above, the high-pressure gas container 10 may further include a charging terminal such as a USB (Universal Serial Bus) terminal. Thereby, the battery 13 can be charged.

In each embodiment described above, the high-pressure gas container 10 may be provided with a power receiving terminal such as a USB terminal instead of being provided with the battery 13 . In this case, the user uses the high pressure gas by supplying power to the high pressure gas container 10 from the outside through the power receiving terminal. Further, when power is not supplied from the power receiving terminal, the controller 15 or the control device 30 controls the opening of the solenoid valve 11 or enables the opening of the manually operated solenoid valve 19 regardless of the state of other sensors. It is also possible not to perform control.

The battery 13, the short-range communication device 14, the controller 15, and the like in each of the above-described embodiments may be realized by a general-purpose computer or the like instead of dedicated hardware. For example, they can be replaced by smart phones. A smart phone can perform short-distance communication by the short-distance communication function provided. Also, by installing an application on the smartphone, the smartphone can execute various processes of the controller 15 .

A combination of the solenoid valve 11 and the manual valve 12 in each of the above-described embodiments can be regarded as one valve. In this case, the valve is opened by operating the manual valve 12 when the solenoid valve 11 is opened. Therefore, by opening the solenoid valve 11, the valve can be opened by manual operation.

The solenoid valve 11 or the manually operated solenoid valve 19 in each embodiment described above is an example of an electrically controllable valve. Although an example in which these are controlled by solenoid actuators has been shown, the scope of the present invention is not limited to this. For example, it may be a valve that can be controlled by pneumatic pressure. In this case, the opening and closing of the valve can be electrically controlled indirectly by electrically controlling the air pressure.

In each of the above-described embodiments, an example was shown in which the control process is terminated in cases other than the case where the valve is made openable by manual operation. However, the control for closing the valve may be performed in cases other than the case where the valve is made openable by manual operation.

Specifically, the short-range communication unit 23 according to the first embodiment, in the electromagnetic valve control process, when the determination unit 22 determines that the position data could not be acquired (step S12: No), or the determination When the unit 22 determines that the position of the portable device 20 is not within the usable range (step S13: No), it transmits control data indicating details of control for closing the electromagnetic valve 11 .

In this way, even if the high pressure gas is once used within the usable range and then moved out of the usable range, the use of the high pressure gas can be restricted.

Each embodiment described above can be combined as appropriate. For example, the second embodiment and the fourth embodiment can be combined. Specifically, control device 30 receives data indicating the measurement result of open/close sensor 18 . Then, the control device 30 transmits control data indicating the control details of the electromagnetic valve 11 to the high-pressure gas container 10 by the same process as the control process of the electromagnetic valve 11 according to the second embodiment.

Also, the third embodiment and the fourth embodiment can be combined. Specifically, the control device 30 transfers control data indicating the details of control of the manually operated solenoid valve 19 to the high-pressure gas container 10 by the same processing as the control processing of the manually operated solenoid valve 19 according to the third embodiment. Send.

Also, the controller 15 of the high-pressure gas container 10 may perform control processing for the solenoid valve 11 or the manually operated solenoid valve 19 . In this case, usable range data 25 is stored in controller 15 . Then, the controller 15 acquires position data from the portable device 20 and, when the position of the portable device 20 is within the usable range, opens the solenoid valve 11 or enables the manually operated solenoid valve 19 to be opened. Control.

Although the present invention has been described above based on each embodiment, the present invention is not limited to the requirements shown in the above embodiments. These points can be changed without impairing the gist of the present invention, and can be determined appropriately according to the application form.
