Description

  The present invention relates to a shut-off system having an operation device that supplies power to a drive control device that controls driving of a plurality of types of shut-off valves having different diameters and communicates with the drive control device.

  The gas shut-off valve has a housing that is inserted and connected via a flange in the middle of the gas pipe, and a valve body and a valve drive mechanism that are detachably provided in the housing. For example, a gas shut-off valve described in Patent Document 1 communicates the interior of a housing having a pair of flanges connected to a gas pipe with a flow passage space communicating with one flange side pipe and the other flange side pipe. A partition wall is provided by partitioning the flow path space, and a ring-shaped nozzle is airtightly attached to a through hole formed in the partition wall, and a flat plate-like valve body is provided to be connectable to the nozzle. The valve body is pressed against the nozzle so as to block the gas inlet-side flow path and the outlet-side flow path of the valve housing.

Further, in order to maintain the function of the gas shut-off valve, it is necessary to replace or perform maintenance and inspection at regular intervals (for example, 10 years). Therefore, in view of the fact that the gas shut-off valve shown in Patent Document 2 has almost no need to replace the housing connected to the gas pipe, the main part including parts that require replacement of the gas shut-off valve is unitized, By replacing only the part of the unit, the base of the shut-off valve unit can be removed from the mounting seat of the housing without removing the housing connected to the gas pipe when replacing the gas shut-off valve. By installing a new shut-off valve unit to be replaced in the housing, the replacement work of the gas shut-off valve can be completed.

Since the registered aperture information corresponding to the shut-off valve can be automatically stored in the operating device, when the drive control device is replaced with a common drive control device that does not store the aperture information, The aperture information can be transmitted to the drive control device for automatic recognition. Therefore, since it is possible to share the drive control device without requiring registration of the diameter of the shutoff valve, it is possible to contribute to the cost reduction of the shutoff system.

  According to the third aspect of the present invention, the drive control device transmits the identification information to the operating device, and the operating device compares the identification information received this time with the previously received identification information to replace the drive control device. Since the aperture information stored in response to the detection of the exchange is transmitted to the drive control device, the aperture information stored in the operating device is driven to be controlled in accordance with the replacement of the drive control device. Since the device can be automatically stored, when the drive control device is replaced with a common drive control device that does not store the aperture information, the common drive control device can quickly control the shutoff valve 20A to be controlled.

That is, by configuring the shutoff valve 20A and the drive control device 20B to be individually replaceable, only the drive control device 20B can be replaced when the drive control device 20B fails.

  The shutoff valve 20A corresponds to the above-described housing of the background art, and is electrically connected to the MPU 21 via a drive unit 27 described later, and a motor drive shutoff valve, a solenoid shutoff valve, or the like is arbitrarily used. It is done. This embodiment demonstrates the case where a motor drive system cutoff valve is used as cutoff valve 20A. When the shutoff valve 20A is closed by the MPU 21, the supply of gas in the pipe 5 is shut off, and when the valve is opened, the supply of gas in the pipe 5 is enabled.

The drive control device usage time 223 is set with total time data indicating the time during which the power supplied from the operation device 10 is energized to the drive control device 20B.

  The diameter 224 of the shutoff valve is set with bore diameter data indicating the diameter of the shutoff valve 20A that is the control target of the drive control device 20B. In addition, since the common drive control device 20B does not know what type of shut-off valve 20A is mounted, only the shut-off valve unit 20 in which the shut-off valve 20A and the drive control device 20B are integrally manufactured, Aperture data is set. At this time, the aperture 224 of the shutoff valve corresponds to the registered aperture information in the claims. In the case of the common drive control device 20B, the diameter data of the shut-off valve 224 is not set.

  When the CPU 21a of the shut-off valve unit 20 receives the shut-off request signal from the operating device 10 via the communication unit 23, the CPU 21a controls the drive unit 27 to close the shut-off valve 26 as described above, and also requests to open. When the signal is received, the drive unit 27 is controlled to open the shutoff valve 26. Thus, the CPU 21a functions as drive control means.

  The pressure sensor 28 is electrically connected to the MPU 21, and a mechanical or electronic sensor that converts a change in air pressure of the gas in the pipe 5 into a pressure signal using a pressure-sensitive element is arbitrarily used. The pressure sensor 28 senses the pressure in the pipe 5 on the downstream side (gas supply side) of the shutoff valve 26 and outputs a pressure signal to the MPU 21.

  Next, operations of various means in the claims shown in FIG. 1 in which the CPU 21a functions by executing various programs by the CPU 21a of the drive control device 20B having the above-described configuration will be described.

  The aperture information receiving means 21a1 of the CPU 21a receives aperture information from various information received from the controller device 10 via the communication unit 23. The unique information extracting means 21a2 of the CPU 21a sets the received bore size information to the bore size 224 of the shutoff valve 20B of the memory unit 22, and uses the bore size information from among a plurality of types of bore size information stored in the memory unit 22. Corresponding unique information is extracted and set as a parameter of the RAM 21c.

  The predetermined process execution means 21a3 of the CPU 21a executes a predetermined process program for performing a predetermined process based on the unique information. That is, the predetermined processing program is a processing program that uses the specific information as a specific parameter of the shutoff valve 20A, and examples of the predetermined processing include a return leak confirmation process and an airtight leak inspection process.

  The registered aperture information transmitting unit 21a4 of the CPU 21a creates registered aperture information including aperture data set in the aperture 224 of the shutoff valve 20A of the memory unit 22, and transmits the registration aperture information to the controller device 10 via the communication unit 23. Then, the identification information transmitting unit 21 a 5 of the CPU 21 a creates identification information and transmits the identification information to the controller device 10 via the communication unit 23. In the present embodiment, a case will be described in which identification information having manufacturing date data set in the shut-off valve unit manufacturing date 221 of the memory unit 22 is created, but the present invention is not limited to this. For example, it can be identification information having various data that can identify the drive control device 20B, such as a manufacturing number (serial number) and a registration number of the drive control device 20B.

"0", "0" for the drive control device usage time 125, and "2" for the aperture 126 are set and updated.

  For example, in the operating state ST3 used for one year, the operating device 10 acquires the use time information from the drive control device 20B, for example, every 24 hours while the drive control device 20B is energized, and shuts off the shut-off valve of the memory unit 12. The set values of the usage time 222 and the drive control device usage time 223 are updated.

  As a result, “8760” written in the shut-off valve use time 222 and the drive control device use time 223 of the memory unit 22 of the drive control device 20 corresponds to the shut-off valve use time 124 and the drive control of the memory unit 12 of the operation device 10. By setting the device usage time 125, the memory unit 12 of the controller device 10 is updated.

  For example, in the state ST4 at the time of display operation of the operation device 10 used for two years, the operation device 10 acquires the use time information from the drive control device 20B, and uses the shut-off valve use time 222 of the memory unit 12 and the drive control device use. The set value of the time 223 is updated and the content is displayed on the display unit 17.

  As a result, “17520” written in the shut-off valve use time 222 and the drive control device use time 223 of the memory unit 22 of the drive control device 20 is the same as the shut-off valve use time 124 and the drive control of the memory unit 12 of the operation device 10. By setting the device usage time 125, the memory unit 12 of the controller device 10 is updated.

  For example, in the state ST5 in which the drive control device 20B used for 10 years is replaced, when the shut-off valve unit 20 is replaced with a new drive control device 20B, as shown in FIG. 8, the memory unit 22 of the drive control device 20B. Is set to "0000/2009" in the shut-off valve unit manufacturing date 221, "0" in the shut-off valve usage time 222, "0" in the drive control device usage time 223, and "0" in the aperture 224, respectively. . That is, only the manufacture date of the drive control device 20B is set in the shut-off valve unit manufacture date 221 and the initial value “0” is set in the aperture 224. Therefore, the drive control device 20B is set in the shut-off valve 20A. In this state, it is impossible to perform various processes according to the aperture.

  When the operation device 10 and the new drive control device 20B are connected and the power supply from the operation device 10 to the new drive control device 20B is started, the drive control device 20B manufactures the shut-off valve unit in the operation device 10. The year / month 221 is transmitted as identification information, the shut-off valve usage time 222 and the drive control device usage time 223 as usage time information, and the aperture 224 as aperture information.

  When the operation device 10 compares the shut-off valve unit manufacturing date 221 of the identification information received this time with the shut-off valve unit manufacture date 123 of the identification information stored in the memory unit 12, the drive control device 10 does not match. It is determined that 20B has been exchanged. Then, the operating device 10 updates the shut-off valve unit manufacturing date 221 of the memory unit 12 by overwriting “1009/1009” with “1009/2009”, and sets “0” for the drive control device usage time 125. The aperture information indicating “2” set in the aperture 126 of the memory unit 12 is created and transmitted to the new drive control device 20B.

  The new drive control device 20B updates the aperture 224 of the memory unit 22 by changing the aperture 224 of the memory unit 22 from “0” to “2” based on the received aperture information, and the unique information corresponding to the aperture information is updated from the memory unit 22. By extracting and setting the unique information, processing suitable for the diameter of the shutoff valve 2A is performed thereafter.

  According to the blocking system 1 described above, the operating device 10 transmits the aperture information to the drive control device 20B, and the unique information corresponding to the aperture information received by the drive control device 20B is extracted from the plurality of unique information, Since the predetermined processing is executed based on the unique information, the aperture information is stored in the operating device 10, so that the aperture information of the shutoff valve 20A can be obtained even if the drive controller 20B is replaced. Since the drive control device 20B can automatically recognize it by 20B, the drive control device 20B can perform various processes suitable for the aperture of the shutoff valve 20A, and the registration work and communication that the operator registers the aperture in the drive control device 20B. A device or the like for registering the aperture can be dispensed with. Therefore, since the diameter of the shutoff valve 20A can be set erroneously, it is not necessary to add an extra bore size detection mechanism for detecting the diameter of the shutoff valve 20A, and the cost of the shutoff system 1 can be prevented from increasing.

  Further, since the drive control device 20B transmits the registered aperture information to the operation device 10 and the operation device 10 stores the received registered aperture information in the memory unit 12 as the aperture information, it corresponds to the shutoff valve 20A. Since the registered aperture information can be automatically stored in the operation device 10, when the drive control device 20B is replaced with a common drive control device 20B that does not store the aperture information, the common drive control from the operation device 10 is performed. The aperture information can be transmitted to the apparatus 20B to be automatically recognized. Therefore, since it is possible to make the drive control device 20B common without requiring registration of the diameter of the shutoff valve 20A, it is possible to contribute to further cost reduction of the shutoff system 1.

  Furthermore, when the drive control device 20B transmits the identification information to the operation device 10 and the operation device 10 detects the replacement of the drive control device 20B by comparing the identification information received this time with the identification information received last time, the replacement is performed. Since the aperture information stored in response to the detection is transmitted to the drive control device 20B, the aperture information stored in the operation device 10 in response to the replacement of the drive control device 20B is transmitted to the drive control device 20B. Since it can be automatically stored, when the drive control device 20B is replaced with a common drive control device 20B that does not store the aperture information, the aperture of the shutoff valve 20A is automatically set to the common drive control device 20B quickly. Can be recognized.
