  In the present embodiment, the control device 1C maintains the state where the second door is electrically locked when the sterilization operation is normally completed. And control device 1C controls an interlock mechanism so that the interlock of the 2nd door may be canceled, when the release demand for releasing the interlock of the 2nd door from state monitoring device 10 is received.

  In the present embodiment, the sterilization apparatus 1 and the state monitoring apparatus 10 are separated, but the state monitoring apparatus 10 may be incorporated in any one of the sterilization apparatuses 1a to 1n.

  With reference to FIG. 2, the example of operation | movement of the state monitoring apparatus 10 in the driving | operation management system 100 is demonstrated. In the example shown in FIG. 1, the sterilizer 1a performs a sterilization operation by executing batch processing. When the batch processing is normally completed, the sterilization apparatus 1a transmits apparatus information D1 and operation information D2 to the state monitoring apparatus 10 as step S1. In this case, in the sterilization apparatus 1a, the first door and the second door are in an interlocked state even if the batch processing is normally completed.

  When the state monitoring device 10 receives the device information D1 and the operation information D2, the state monitoring device 10 determines whether the physical condition is satisfied in the batch processing based on the processing content of the batch processing indicated by the operation information D2. The state monitoring device 10 stores physical conditions in advance. The physical condition is a condition for determining a processing content in which sterilization of the workpiece is effective. Physical conditions include, for example, temperature, pressure, and time ranges and thresholds during the sterilization process. The state monitoring apparatus 10 may determine that the object to be processed may be taken out from the processing tank when the processing content satisfies physical conditions. The physical conditions are determined in advance based on, for example, the sterilization management method for the facility in which the sterilizer 1 is provided, and examples of the physical conditions will be described later.

  When it is determined that the physical condition is satisfied in the batch processing, that is, when the processing object may be taken out from the processing tank, the state monitoring apparatus 10 may take out the processing object from the processing tank as Step S2 ( The determination result D3 and the operation information D2 are transmitted to the administrator's portable communication terminal device 7B via the communication line 3.

  When mobile communication terminal device 7B receives determination result D3 and driving information D2 from state monitoring device 10, it creates a screen for displaying determination result D3 and driving information D2. The mobile communication terminal device 7B displays the created screen on the display device of the mobile communication terminal device 7B. Thereby, the administrator confirms that the sterilization of the object to be processed is effective, that is, the determination result of the state monitoring apparatus 10 that the object to be processed can be taken out from the sterilization apparatus 1a by referring to the screen. be able to. Thereby, the administrator can permit the operator of the sterilizer 1a to pay out the object to be processed.

  In this way, the state monitoring device 10 transmits the processing content executed by the sterilization device 1a to the administrator's portable communication terminal device 7B. For this reason, the administrator can determine the effectiveness of sterilization of the object to be processed after the sterilization operation is normally completed based on the processing content received by the mobile communication terminal device 7B. In addition, the convenience of paying out the processed object can be improved.

  The state monitoring device 10 determines whether or not a physical condition that can determine that the processing object may be taken out from the processing tank is satisfied based on the physical condition when the processing object is processed, and the determination result Is transmitted to the portable communication terminal device 7B of the administrator. For this reason, even if the administrator does not determine the effectiveness of the sterilization of the object to be processed, the administrator can quickly permit the dispensing of the object to be processed from the determination result of the state monitoring device 10.

  When the state monitoring device 10 determines that the physical condition that allows the processing object to be taken out from the processing tank of the sterilization device 1a is satisfied, the state monitoring device 10 sets the interlock of the second door of the sterilization device 1a as step S3. A signal indicating a release request D4 for release is transmitted to the sterilizer 1a. And sterilizer 1a will release the interlock of the 2nd door, if cancellation demand D4 is received. Thereby, the sterilizer 1a will be in the state which can take out a to-be-processed object from the inside of a processing tank.

  As described above, the state monitoring device 10 determines that the physical condition that can determine that the processing object may be taken out from the processing tank is satisfied based on the physical condition when the processing object is processed. When it does, the interlock of the 2nd door of the sterilizer 1a is cancelled | released. For this reason, when the administrator instructs the operator of the sterilizer 1a to pay out, the interlock of the second door of the sterilizer 1a is released. As a result, the operator can quickly pay out a workpiece to be sterilized from the sterilization apparatus 1a.

  In addition, when the state monitoring device 10 determines that the physical condition that can determine that the processing object may be taken out from the processing tank is not satisfied based on the physical condition when the processing object is processed. The determination result indicating that the processing content is NG and the operation information are transmitted to the administrator's mobile communication terminal device 7B via the communication line 3. In this case, although the sterilization apparatus 1a is normally completed, it is determined that the effectiveness of sterilization is doubtful. The state monitoring device 10 may transmit the determination result indicating that the processing content is NG and the operation information to the computer 6 at the management base.

  When the mobile communication terminal device 7B receives the determination result and the driving information from the state monitoring device 10, the mobile communication terminal device 7B creates a screen showing the determination result and the driving information. The mobile communication terminal device 7B displays the created screen on the display device of the mobile communication terminal device 7B. When the administrator refers to the screen displayed on the display device of the mobile communication terminal device 7B, the administrator does not satisfy the physical condition that can determine that the object to be processed can be taken out, that is, the object to be processed from the sterilizer 1a. It is possible to confirm the determination result of the state monitoring apparatus 10 that the information cannot be taken out. For this reason, the administrator can confirm that the effectiveness of the sterilization of the workpiece is questionable.

In addition, the fact that the sterilization temperature and the holding time satisfy physical conditions means that sterilization of the object to be processed is also effective. The relationship between the sterilization temperature and the holding time is not limited to the above-described relationship, and can be set according to the operating conditions in each facility.

  FIG. 5 is a flowchart illustrating an example of a processing procedure for transmitting information to the mobile communication terminal device. With reference to FIG. 5, the process procedure which the process part 11 of the state monitoring apparatus 10 performs is demonstrated.

  As illustrated in FIG. 5, the processing unit 11 of the state monitoring device 10 determines whether the operation of the sterilizer 1 is normally completed in step S <b> 101. Specifically, when the apparatus information received from the sterilizer 1 indicates normal termination, the processing unit 11 determines that the operation of the sterilizer 1 is normally terminated. If the control unit 11 determines that the operation is not normally completed (step S101, No), the process proceeds to step S108. On the other hand, when the control unit 11 determines that the operation is normally completed (step S101, Yes), the process proceeds to step S102.

  The process part 11 receives the information regarding a process content as step S102. In step S103, the processing unit 11 determines, based on the processing content, whether or not a physical condition that can determine that the workpiece may be taken out from the processing tank of the sterilizer 1 is satisfied, and stores the determination result. Store in unit 12. Then, when the processing unit 11 determines that the physical condition that can determine that the object to be processed can be taken out is satisfied (step S104, Yes), the processing unit 11 proceeds to step S105. In step S105, the processing unit 11 sends information including the determination result that the physical condition that can determine that the object to be processed can be taken out and the processing content is satisfied to the portable communication terminal device 7B of the predetermined administrator. Send. And the process part 11 transmits the cancellation | release request | requirement of an interlock to the sterilizer 1 as step S106, and progresses to step S108.

  When it is a physical condition determined that the processing of the object to be processed is insufficient (No at Step S104), the processing unit 11 proceeds to Step S107. In step S107, the processing unit 11 obtains information including a determination result that the physical condition that can determine that the object to be processed may be taken out and a processing content is not satisfied, and a portable communication terminal device of a predetermined administrator. 7B and proceed to step S108.

  The process part 11 determines whether it is complete | finished as step S108. Specifically, when a termination request is received by a termination operation or the like, the processing unit 11 determines that the termination has been completed. If the processing unit 11 determines that the processing is not finished (No at Step S108), the processing unit 11 returns to Step S101. If the processing unit 11 determines that the processing is finished (step S108, Yes), the processing procedure is finished.

  In the present embodiment, as the steps S105 and S107, the processing unit 11 has described the case of transmitting information including the determination result and the processing content only to the administrator's mobile communication terminal device 7B. However, the transmission method of information including the determination result and the processing content is not limited to this. For example, when the operation ends normally, the processing unit 11 may transmit information including the determination result and the processing content to the mobile communication terminal device 7A of the operator. Alternatively, the processing unit 11 may transmit information including the determination result and the processing content to the administrator's mobile communication terminal device 7B and the operator's mobile communication terminal device 7A regardless of the operation result.

  FIG. 6 is a diagram illustrating an example of a screen displayed by the mobile communication terminal device. A screen 70 shown in FIG. 6 displays the processing contents of the batch processing executed by the sterilization apparatus 1 and the determination result by the state monitoring apparatus 10. The screen 70 includes at least one item such as a unit, operation, average temperature, maximum temperature, minimum temperature, average pressure, maximum pressure, minimum pressure, holding time, F value, and determination result. Information for identifying the sterilizer 1 is displayed in the item of No. machine. In the operation item, information indicating the operation mode of the sterilizer 1 is displayed. For example, the operation mode of the sterilizer includes at least one of a standard sterilization operation, a high-temperature sterilization operation, a high-speed sterilization operation, and the like. In the item of average temperature, an average temperature during the sterilization process is displayed. In the items of maximum temperature and minimum temperature, the maximum temperature and the minimum temperature during the sterilization process are displayed. In the item of average pressure, the average pressure during the sterilization process is displayed. In the items of maximum pressure and minimum pressure, the maximum pressure and the minimum pressure during the sterilization process are displayed.

  In the example shown in FIG. 6, the screen 70 displays physical information such as average temperature, maximum temperature, minimum temperature, average pressure, maximum pressure, minimum pressure, holding time, and F value as processing contents, and also monitors the status. It is displayed that the determination result by the device 10 is OK. By referring to this screen 70, the administrator satisfies that the physical condition that can determine that the object to be processed can be taken out from the treatment tank of the sterilizer 1 from the sterilizer 1 whose operation has ended normally is satisfied. Can be confirmed. Alternatively, when the determination result by the state monitoring device 10 is OK, the administrator can determine whether or not the workpiece can be taken out by referring to the physical information of the processing content.

  In this embodiment, when the operation of the sterilizer 1 ends normally, the state monitoring apparatus 10 may take out the object to be processed from the processing tank based on physical conditions when the object is processed. The case where it is determined whether or not the physical condition that can be determined is satisfied has been described. However, the state monitoring device 10 does not have to determine whether the physical condition is satisfied. For example, the state monitoring device 10 does not determine whether or not the physical condition is satisfied, and sends information related to the processing content received from the sterilizer 1 to the administrator's mobile communication terminal device 7B via the communication line 3. Send. In this case, the administrator determines whether or not the object to be processed can be taken out from the processing tank of the sterilizer 1 based on the information regarding the processing content displayed on the mobile communication terminal device 7B.

  The state monitoring device 10 described above may store, for example, operation information indicating the operation history of the sterilizer 1 and the status of the sterilizer 1 currently operating in the storage unit 12. In this case, when receiving a transmission request from the administrator's portable communication terminal device 7B, the state monitoring device 10 transmits the operation information of the sterilizer 1 specified by the transmission request to the portable communication terminal device 7B. In this way, the administrator predicts the operation completion time by confirming the operation status of the sterilizer 1, and the operator or the user of the object to be processed sends the object to be processed from the sterilizer 1. Can tell the time of payment. For this reason, the state monitoring apparatus 10 can further improve the convenience relating to the dispensing of the workpiece sterilized by the sterilization apparatus 1.

  Although the present embodiment has been described above, the present embodiment is not limited to the above-described content. In addition, the above-described constituent elements include those that can be easily assumed by those skilled in the art, those that are substantially the same, and those in a so-called equivalent range. Furthermore, the above-described components can be appropriately combined. Furthermore, various omissions, substitutions, or changes of components can be made without departing from the scope of the present embodiment.
