Description

The present invention relates to a pressure regulation system and a program for the pressure regulation system.

As a pressure regulating system used for regulating the pressure inside a work (for example, a tire) filled with a fluid, for example, Patent Document 1 discloses a connecting portion detachably connected to the work, and the connecting portion a switching mechanism for switching between an inflow/outflow state in which fluid flows into and out of a space communicating with the fluid, and a stop state in which fluid flow into and out of the space is stopped; and a pressure sensor that detects the pressure in the space in the stop state. and a display section for displaying the pressure value detected by the pressure sensor, and a user operates the switching mechanism based on the pressure value displayed on the display section while the connection section is connected to the workpiece. to adjust the pressure in the work.

By the way, when performing adjustment work using the above-mentioned conventional pressure adjustment system, if you try to record the pressure value after the adjustment is completed as a work record, you have to pick up a writing utensil and take notes every time the adjustment work is completed. It was very inefficient.

On the other hand, if the conventional pressure regulating system is configured so that the pressure value detected by the pressure sensor is automatically stored in a memory or the like, there is no need to take notes, and work efficiency is improved. However, in the pressure regulating system, the pressure sensor cannot accurately detect the pressure inside the workpiece unless it is in a stopped state. Therefore, when performing adjustment work using the pressure adjustment system, while repeatedly switching between the inflow/outflow state and the stopped state by the switching mechanism, the pressure value displayed on the display unit in the stopped state is referred to. The pressure value is adjusted so that it approaches the set pressure set for the workpiece. Therefore, if all the pressure values detected by the pressure sensor in the stopped state are stored, each time the switching mechanism switches to the stopped state, the pressure value detected by the pressure sensor at that time is stored, resulting in a large amount of data. As the pressure increases, it becomes troublesome to manage the pressure value required as a work record.

Registered Utility Model No. 3075397

Therefore, the main object of the present invention is to provide a pressure adjustment system that automatically stores necessary pressure values as work records such as pressure values after completion of adjustment, and can suppress storage of unnecessary pressure values. It is an important issue.

That is, the pressure regulating system according to the present invention includes a connecting portion detachably connected to a workpiece, and at least one of a state in which a fluid flows into a space communicating with the connecting portion and a state in which the fluid flows out from the space. and a stop state that stops the flow of fluid into and out of the space, a pressure sensor that detects the pressure in the space in the stop state, and a pressure value detected by the pressure sensor. and a display unit that displays a pressure in the work by a user operating the switching mechanism based on the pressure value displayed on the display unit while the connection unit is connected to the work. A pressure regulating system, comprising: an elapsed time measuring unit for measuring an elapsed time from a predetermined time point after each switching of the switching mechanism from the inflow/outflow state to the stopped state; a pressure value storage unit that stores the pressure value detected by the pressure sensor in the stopped state when the elapsed time exceeds a predetermined set time before switching from the inflow/outflow state to the inflow/outflow state; It is characterized by having

With such a configuration, each time the switching mechanism is switched from the inflow/outflow state to the stopped state, the elapsed time from a predetermined point after the switching is measured, and before the switching mechanism is switched from the inflow/outflow state to the inflow/outflow state. Further, when the elapsed time exceeds a predetermined set time, the pressure value detected by the pressure sensor in the stopped state is stored. When switching to the inflow/outflow state before, the pressure value detected in the stopped state is no longer stored, and the storage of the pressure value detected during adjustment can be suppressed. On the other hand, the pressure value after completion of the necessary adjustment is reliably stored as a work record. That is, after switching to the stopped state by the switching mechanism, if the user determines that the pressure value displayed on the display unit during the stopped state is significantly lower or higher than the set pressure, the operation of switching to the inflow/outflow state again. to run. Therefore, by setting the set time longer than the time until the user checks the pressure value displayed on the display and executes the operation to switch to the inflow/outflow state again, the pressure value detected during adjustment can be suppressed from being stored. After switching to the stopped state by the switching mechanism, if the user determines that the pressure value displayed on the display unit in the stopped state has reached the vicinity of the set pressure, the operation of switching to the inflow/outflow state is not performed again. . Therefore, the pressure value detected after the adjustment is completed can be reliably stored.

In the present invention, the pressure value detected by the pressure sensor indicates the pressure value in a state in which turbulence or the like is hardly generated in the space communicating with the connection portion. That is, for example, immediately after connecting the connecting portion to the work or immediately after switching from the inflow/outflow state to the stop state by the switching mechanism, turbulent flow occurs in the work and accurate internal pressure cannot be detected. shows the pressure value detected in a state in which the

The predetermined time is, for example, a time when a pressure value is detected by the pressure sensor after the switching mechanism has been switched from the inflow/outflow state to the stop state, or a time when the pressure value is displayed on the display unit. The indicated time points are included.

In some cases, the pressure value before adjustment is also required as a work record. Therefore, the pressure value storage unit may store a pressure value first detected as a pressure value exceeding a predetermined threshold value by the pressure sensor.

With such a device, not only the pressure value after adjustment but also the pressure value before adjustment can be stored as a work record.

More specifically, the connecting portion communicates with the atmospheric space when it is not connected to the workpiece. In this case, the atmospheric pressure is detected by the pressure sensor. When the connecting portion is connected to the work from this state, the connecting portion becomes in a state of communicating with the inside of the work, and the pressure value detected by the pressure sensor at this time becomes the pressure value of the work before adjustment. Therefore, the pressure value that first exceeds the threshold value after connecting the connecting portion to the workpiece is the pre-adjustment pressure value. Therefore, by configuring as described above, the pre-adjustment pressure value can be reliably stored.

As the threshold value, a value lower than the set pressure set for the workpiece and higher than the atmospheric pressure may be set.

Moreover, it may further include a sensor correcting section that corrects the zero point of the pressure sensor based on the atmospheric pressure when the power of the pressure adjusting system is turned on.

With such a configuration, the pressure sensor is always zero-point corrected before the adjustment work is started, so that the pressure sensor can more accurately detect the pressure relative to the atmospheric pressure in the workpiece. .

Further, as a specific configuration of the pressure regulating system, a pressure regulating device including the connection portion, the switching mechanism, and the pressure sensor, and the pressure value storage portion, which is separate from the pressure regulating device, and a pressure value management device, wherein the pressure adjustment device and the pressure value management device are connected by wire or wirelessly, and either one or both of the pressure adjustment device and the pressure value management device One having the display section is mentioned.

With such a device, the pressure adjusting device and the pressure value management device can be separated from each other, so that the pressure adjusting device can be downsized and can be easily handled during adjustment work.

Further, the program for a pressure regulating system according to the present invention includes a connecting portion detachably connected to a workpiece, and at least one of a state in which a fluid flows into a space communicating with the connecting portion and a state in which the fluid flows out from the space. a switching mechanism for switching between an inflow/outflow state that is a state of and a stop state that stops the inflow and outflow of fluid to and from the space; a pressure sensor that detects the pressure in the space in the stop state; a display unit for displaying a pressure value, and in a state in which the connection unit is connected to the work, the user operates the switching mechanism based on the pressure value displayed on the display unit to change the pressure in the work. A program used in a pressure regulating system for adjusting the A pressure that stores the pressure value detected by the pressure sensor in the stopped state when the elapsed time exceeds a predetermined set time before the switching mechanism is switched from the stopped state to the inflow/outflow state. It is characterized by exhibiting a function as a value storage section.

Further, the pressure regulating system according to the present invention includes a connecting portion detachably connected to a workpiece, and at least one of a state in which a fluid flows into a space communicating with the connecting portion, and a state in which the fluid flows out from the space. and a stop state that stops the flow of fluid into and out of the space, a pressure sensor that detects the pressure in the space in the stop state, and a pressure value detected by the pressure sensor. and a display unit that displays a pressure in the work by a user operating the switching mechanism based on the pressure value displayed on the display unit while the connection unit is connected to the work. In the pressure regulating system, when a pressure value equal to or less than the threshold value is detected after the pressure value exceeding the predetermined threshold value is detected by the pressure sensor, immediately before the pressure value equal to or less than the threshold value is detected. It is characterized by further comprising a pressure value storage section for storing the pressure value detected in the first step.

Even in such a case, after a pressure value exceeding a predetermined threshold is detected by the pressure sensor, when a pressure value equal to or less than the threshold is detected, a pressure value equal to or less than the threshold is detected. Since the pressure value detected immediately before is stored, the pressure value after completion of adjustment necessary as a work record is stored in the pressure value storage unit.

More specifically, when the user performs adjustment work, step 1 turns on the power of the pressure adjustment system, step 2 connects the connecting portion to the work, and then the Step 3 of repeating the switching operation of the switching mechanism while referring to the pressure value and adjusting the pressure value displayed on the display unit so as to approach the set pressure set for the work; Step 4 of removing the connecting portion from the work; will be executed sequentially. Therefore, by setting the threshold to a value smaller than the set pressure and larger than the atmospheric pressure, when steps 2 and 3 are performed, a pressure value exceeding the threshold is detected by the pressure sensor, and then step 4 is performed. When done, the pressure sensor detects a pressure value below the threshold. That is, in step 3, the user judges that the adjustment work is completed when the pressure value displayed on the display unit is close to the set value, and proceeds to step 4, so that the series of adjustment work is executed. In this case, detection of a pressure value equal to or lower than the threshold value by the pressure sensor signals completion of the adjustment work. Therefore, when a pressure value equal to or less than a threshold value is detected by the pressure sensor, if the pressure value detected immediately before the pressure value equal to or less than the threshold value is detected, only the pressure value after adjustment is completed can be stored. can be stored automatically.

According to the pressure regulating system configured in this manner, the pressure value after adjustment and the pressure value before adjustment, which are necessary as work records, are automatically stored, and unnecessary pressure values can be prevented from being stored.

A pressure regulation system according to the present invention will be described below with reference to the drawings.

A pressure regulating system according to the present invention is used for regulating the pressure (internal pressure) within a work filled with fluid. Specifically, it is used to adjust the pressure inside the work so as to approach a predetermined set pressure. In addition, a tire etc. are mentioned as a workpiece|work.

<Embodiment 1> As shown in FIG. 1, a pressure regulating system 100 according to this embodiment includes a pressure regulating device 10 for regulating the pressure inside a work W, and a pressure regulating device 10 that are separate from the pressure regulating device. and a pressure value management device 20 connected to the device 10 by wire or wirelessly.

The pressure regulating device 10 is a so-called inflator. Specifically, the pressure regulating device 10 includes a switching mechanism 11 that operates the inflow and outflow of fluid to and from the work W, a pressure sensor 12 that detects the pressure inside the work W, and a pressure value detected by the pressure sensor 12. A display unit 13 for displaying and communication means 14 for communicating with the pressure value management device 20 are provided. The pressure regulating device 10 further includes a hose-like connecting portion 15 connected to the work W so as to communicate with the inside of the work W. As shown in FIG. A fluid supply tank (not shown) is connected to the pressure regulating device 10 . The fluid supply tank supplies fluid to the pressure adjusting device 10 at a pressure higher than the pressure inside the workpiece W. As shown in FIG.

The switching mechanism 11 has an inflow/outflow state, which is at least one of a state in which the fluid flows into the work W through the connection portion 15 and a state in which the fluid flows out from the work W, and a state in which the fluid flows into the work W. A state in which the fluid is not allowed to flow out from the workpiece W and a state in which the fluid is not allowed to flow out are switched. The switching mechanism 11 of this embodiment is of a trigger type, and is configured so that when the trigger is squeezed, it enters an inflow/outflow state, and when the trigger is released, it automatically enters a stopped state. The switching mechanism 11 is not limited to the trigger type, and may be, for example, a button type. It is preferable that the switching mechanism 11 automatically switches from the inflow/outflow state to the stop state in a state in which no external force is applied as in the present embodiment.

The pressure sensor 12 detects the pressure in the space communicating with the connecting portion 15 , specifically, the atmospheric space and the space inside the work W when the switching mechanism 11 is switched to the stopped state.

The display unit 13 displays the pressure detected by the pressure sensor 12 so that the user can visually recognize it. Note that the display unit 13 of the present embodiment is of a digital type. The display unit 10 is not limited to the digital type, and may be of the analog type.

The communication means 14 is for transmitting pressure value data indicating the pressure value detected by the pressure sensor 12 to the pressure value management device 20 .

The pressure adjusting device 10 also includes a pressure sensor 12 , a display section 13 , and a control section C<b>1 connected to communication means 14 . The control unit C1 is, for example, a computer having a CPU, memory, input/output means, an A/D/D/A converter, etc. Based on the control program stored in the memory, the pressure value temporary storage unit C1a , a display control unit C1b, a zero point correction unit C1c, an elapsed time measurement unit C1d, a recording determination unit C1e, a threshold storage unit C1f, a set time storage unit C1g, and a data transmission unit C1h. .

The pressure value temporary storage section C1a temporarily stores the pressure value detected by the pressure sensor 12. As shown in FIG. Specifically, the pressure value temporary storage section C1a stores the pressure value detected by the pressure sensor 12 whenever the switching mechanism 11 is in a stopped state. That is, the pressure value temporary storage section C1a stores a new pressure value each time the pressure sensor 12 detects a new pressure value.

The display control section C1b outputs to the display section 13 the latest pressure value stored in the pressure value temporary storage section C1a.

The zero point correction unit C1c acquires the pressure value (atmospheric pressure) written in the pressure value temporary storage unit C1a at that time when the start signal indicating that the power is turned on is received, and the pressure sensor 12 is zeroed. It corrects the points.

The elapsed time measuring section C1d measures the elapsed time from a predetermined time point after the switching mechanism 11 switches from the inflow/outflow state to the stop state. It should be noted that the elapsed time measurement unit C1d of the present embodiment measures the elapsed time from the time when the pressure value is detected by the pressure sensor 12 after each switching mechanism 11 switches from the inflow/outflow state to the stop state. It measures The elapsed time measurement unit C1d measures the elapsed time from the point in time when the pressure value detected by the pressure sensor 12 was displayed on the display unit 13 after each switching from the inflow/outflow state to the stop state by the switching mechanism 11. It may be one that measures time. Further, the elapsed time measuring section C1d may measure the elapsed time immediately after the switching each time the switching mechanism 11 switches from the inflow/outflow state to the stop state.

The recording determination unit C1e acquires the latest pressure value stored in the pressure value temporary storage unit C1a, acquires the elapsed time from the elapsed time measurement unit C1d, and detects a pressure value from the pressure sensor 12. receive a signal. Then, the threshold value stored in the threshold storage unit C1f and the set time stored in the set time storage unit C1g are referenced to determine whether or not to record the latest pressure value. Specifically, the recording determination unit C1e makes a first determination of whether or not the acquired pressure value exceeds a threshold value, and if it is determined that the acquired pressure value exceeds the threshold value in the first determination, the acquired pressure value a second determination of whether the value first exceeds the threshold, and the elapsed time until the detection signal is received if the second determination determines that the value does not first exceed the threshold. and a third determination of whether or not the set time has passed.

When the recording determination unit C1e determines in the second determination that the acquired pressure value first exceeds the threshold value, the acquired pressure value is changed to the pre-adjustment pressure value indicating the pre-adjustment pressure value. It is designed to be output as data to the data transmission section C1h. Further, when the recording determination unit C1e determines in the third determination that the elapsed time until the detection signal is received exceeds the set time, the pressure value acquired before the detection signal is received is is output to the data transmission section C1h as adjusted pressure value data indicating the pressure value of .

The threshold is stored in the threshold storage section C1f. Here, the threshold value is set to a pressure value higher than the set pressure set for the workpiece W and lower than the atmospheric pressure. In the present embodiment, the same numerical threshold is used for the first determination and the third determination, but different numerical thresholds may be used.

Further, the set time is stored in the set time storage section C1g. Here, the set time is set after the user switches from the inflow/outflow state to the stop state by the switching mechanism 11, confirms the pressure value displayed on the display unit 13, and confirms that the pressure value reaches the vicinity of the set pressure. It is determined in consideration of the time until the switching mechanism 11 switches from the stop state to the inflow/outflow state again when it is determined not to do so. Specifically, the set time is preferably set to 0.5 seconds or more and 3 seconds or less, and more preferably set to 1 second or more and 2 seconds or less. Note that the set time storage section C1g may be configured so that the set time can be input by input means or the like.

The data transmission unit C1h transmits the pre-adjustment pressure value data and the post-adjustment pressure value data received from the recording determination unit C1e to the pressure value management device 20. FIG.

The pressure value management device 20 has a display (screen) D, input means, etc., and a control section C2. The pressure value management device 20 of the present embodiment is a mobile terminal having a touch panel display that can be carried by the user, such as a smartphone or a tablet terminal that can wirelessly communicate with the pressure adjustment device 10 . The control unit C2 is, for example, a computer having a CPU, a memory, an A/D/D/A converter, etc. Based on the control program stored in the memory, the data receiving unit C2a, the pressure value storage It is configured to exhibit the functions of the section C2b and the display control section C2c.

The data receiving section C2a receives the pre-adjustment pressure value data and the post-adjustment pressure value data transmitted from the data transmission section C1f, and outputs them to the pressure value storage section C1b and the display control section C2c.

The pressure value storage section C2b stores the pre-adjustment pressure value data and the post-adjustment pressure value data output from the data reception section C2a.

The display control section C2c displays on the display D the pressure value indicated by the pre-adjustment pressure value data and the post-adjustment pressure value data output from the data reception section C2a.

Next, the operation of the pressure regulation system 100 of this embodiment will be described.

When the user turns on the power of the pressure regulating device 10 in a state in which the connecting portion 15 is not connected to the workpiece W, the pressure sensor 12 detects the pressure of the atmospheric space communicating with the connecting portion 15, in other words, the atmospheric pressure. do. Then, the zero point correction unit C1c corrects the zero point of the pressure sensor 12 based on the atmospheric pressure detected by the pressure sensor 12 (step S1). Incidentally, when the user turns on the power of the pressure regulating device 10 while the connecting portion 15 is connected to the workpiece W, an error is displayed on the display portion 13 .

Next, when the user connects the connecting portion 15 to the work W, the pressure sensor 12 detects the pressure in the space within the work W communicating with the connecting portion 15, in other words, the internal pressure. Further, after that, the pressure sensor 12 detects the internal pressure every time the user operates the switching mechanism 11 to switch from the inflow/outflow state to the stop state while the connecting portion 15 is connected to the workpiece W (step S3). . The pressure value temporary storage unit C1a stores the pressure value (internal pressure) detected by the pressure sensor 12 at any time (step S2). Each time a new pressure value is stored in the pressure value temporary storage unit C1a, the display control unit C1b acquires the latest pressure value from the pressure value temporary storage unit C1a, and displays the acquired pressure value on the display unit. 13.

In addition, the elapsed time measurement unit C1d measures the elapsed time from the point in time when the pressure value is detected by the pressure sensor 12 after the switch every time the user switches from the inflow/outflow state to the stop state by the switching mechanism 11. (Step S2).

Each time a new pressure value is stored in the pressure value temporary storage unit C1a, the recording determination unit C1e acquires the latest pressure value from the pressure value temporary storage unit C1a, and also acquires the elapsed time value from the elapsed time measurement unit C1d. The time is obtained, and the threshold value stored in the threshold storage unit C1f and the set time stored in the set time storage unit C1g are referred to. It is determined whether or not to record the acquired pressure values by sequentially performing the determinations (steps S6 and S8).

Specifically, if the recording determination unit C1e determines in the first determination that the acquired pressure value exceeds the threshold, then it performs the second determination. On the other hand, when it is determined in the first determination that the acquired pressure value does not exceed the threshold value, a newly stored pressure value is acquired from the pressure value temporary storage section C1a.

Next, when the recording determination unit C1e determines in the second determination that the acquired pressure value is the pressure value that first exceeds the threshold value, the acquired pressure value is used as the pre-adjustment pressure value and data is transmitted. C1h, and stored in the pressure value storage unit C2b of the pressure value management device 20 (step S5). After that, the newly stored pressure value is acquired from the pressure value temporary storage section C1a. On the other hand, if it is determined in the second determination that the acquired pressure value does not first exceed the threshold value, then the third determination is performed.

Next, in the third determination, the recording determination unit C1e determines whether or not the elapsed time until receiving a new detection signal has exceeded the set time (steps S6 and S8). Specifically, the recording determination unit C1e determines whether or not the elapsed time exceeds the set time in the third determination. The pressure value is transmitted to the data transmission unit C1h as the pressure value after adjustment is completed, and is stored in the pressure value storage unit C2b of the pressure value management device 20 (step S7). After that, the adjustment work is finished.

On the other hand, when the recording determination section C1e determines in the third determination that the elapsed time has not exceeded the set time, it subsequently determines whether or not a new detection signal has been received. Then, in the determination, when it is determined that the detection signal has been received, a newly stored pressure value is acquired from the pressure value temporary storage section C1a. If it is determined in this determination that the detection signal has not been received, it is determined again whether or not the elapsed time has exceeded the set time. That is, the memory determination unit C1e repeatedly performs the third determination until the elapsed time exceeds the set time or until the detection signal is received.

Note that when a pressure value newly stored in the pressure value temporary storage unit C1a is obtained in the recording determination unit C1e, the first to third determinations are performed for the newly obtained pressure value.

With such a configuration, unless an irregular state such as a user makes a mistake occurs, when the adjustment work is completed, the pressure value storage unit C1b of the pressure value management device 20 stores the work record Only necessary pre-adjustment pressure value data indicating the pre-adjustment pressure value and post-adjustment pressure value data indicating the post-adjustment pressure value are stored.

<Embodiment 2> This embodiment is a modification of the pressure regulation system 100 according to the first embodiment.

When the recording determination unit C1e determines in the second determination that the acquired pressure value first exceeds the threshold value, the acquired pressure value is the pre-adjustment pressure value before adjustment. It is designed to be output to the data transmission section C1h as pressure value data. Further, when the recording determination unit C1e determines in the third determination that the previously acquired pressure value exceeds the threshold, the adjusted pressure value data indicating the pressure value after adjustment of the previously acquired pressure value is completed. , and is output to the data transmission unit C1f.

Next, the operation of the pressure regulation system 100 of this embodiment will be described.

Each time a new pressure value is stored in the temporary pressure value storage unit C1a, the recording determination unit C1d acquires the latest pressure value from the temporary pressure value storage unit C1a, and uses the threshold value stored in the threshold value storage unit C1f. It is determined whether or not to record the pressure value acquired by sequentially performing the first determination (step S3), the second determination (step S4), and the third determination (step S6).

Specifically, if the recording determination unit C1e determines in the first determination that the acquired pressure value exceeds the threshold, then it performs the second determination. On the other hand, if it is determined in the first determination that the acquired pressure value does not exceed the threshold value, then the third determination is performed.

Next, when the recording determination unit C1e determines in the second determination that the acquired pressure value is the pressure value that first exceeds the threshold value, the acquired pressure value is used as the pre-adjustment pressure value and data is transmitted. C1h, and stored in the pressure value storage unit C2b of the pressure value management device 20 (step S5). After that, the newly stored pressure value is acquired from the pressure value temporary storage section C1a.

On the other hand, when it is determined in the second determination that the acquired pressure value does not first exceed the threshold value, a newly stored pressure value is acquired from the pressure value temporary storage section C1a.

Next, when the recording determination unit C1e determines in the third determination that the previously acquired pressure value exceeds the threshold value, the previously acquired pressure value is sent to the data transmission unit C1h as the pressure value after the completion of adjustment. It is transmitted and stored in the pressure value storage unit C2b of the pressure value management device 20 (step S7). After that, the adjustment work is finished.

On the other hand, when the recording determination unit C1e determines in the third determination that the previously obtained pressure value does not exceed the threshold value, the recording determination unit C1e stores the pressure value in the pressure value storage unit C2b of the pressure value management device 20 .

Note that when a pressure value newly stored in the pressure value temporary storage unit C1a is obtained in the recording determination unit C1e, the first to third determinations are performed for the newly obtained pressure value.

With such a configuration, when the adjustment work is completed, the pre-adjustment pressure value data indicating the pre-adjustment pressure value necessary for the work record and , only the post-adjustment pressure value data indicating the pressure value after the adjustment is completed is stored.
