  The beneficiary device 30A is required for making a search request to the above-described index server 23 using the mail transmission information (station + relative position / search key) and confirming the transmission result (plant answer). The actual address (station + relative position + N) of the plant answer is obtained. The index server 23 extracts N from the search key and transmits the answer data to the beneficiary device 30A. The beneficiary device 30 </ b> A receives the plant answer sent from the field server device 11 </ b> A <b> 2 based on the obtained actual address of the plant answer, and displays the search result. In addition, the beneficiary device 30A does not perform the request timing to the index server 23 immediately after the e-mail transmission, but waits for a certain time after the e-mail transmission to take into account the response time of the plant 12A, and displays the search result. Execute. This makes it possible to determine whether the operation has been performed reliably or has failed. The beneficiary device 30 </ b> A can select an automatic search activation that automatically confirms the display of the search result in accordance with the above procedure from the mail transmission and a manual search activation that is used when reconfirmation of failure.

  FIG. 11 is a diagram for explaining ensuring consistent and unified availability. In the cloud system shown in FIG. 11, a plurality of information processing engine devices 20A to 20C are provided for one machine place 10A. The information processing engine apparatuses 20A to 20C are the same as those having the configuration shown in FIG. Similarly to the above, the field server device 11A includes a plurality of field servers 11A1 and 11A2 that can execute processing of the same content.

  The information processing engine devices 20A to 20C execute processing by selectively switching the field server devices 11A1 and 11A2 to be requested according to the movable state of the requested device. The field server devices 11A1 and 11A2 execute processing by selectively switching the information processing engine devices 20A to 20C to be requested according to the movable state of the information processing engine devices 20A to 20C. This

  Next, the redundancy processing of the field server device will be described. FIG. 12 is a diagram for explaining the redundancy processing of the field server device. The field server device 11 includes at least two field server devices 11A1 and 11A2 that execute redundancy processing.

  During normal operation, the first field server device 11A1 is operating and the second field server device 11A2 is on standby. When an abnormality has occurred in the movable first field server device 11A1, the second field server device 11A2 operates in place of the first field server device 11A1. As an abnormality target of the field server device 11A, there are hardware, firmware, platform, application, and the like of the field server device 11A.

  The field server device 11A sends a failure warning to the beneficiary device 30 via electronic mail. When the first field server device 11A1 breaks down, the second field server device 11A2 executes the process in place of the first field server device 11A1. If the first field server device 11A1 fails and cannot be automatically restored, a person repairs the failure and restores it.

  Next, a process for optimizing information storage in the field server device will be described. 13 and 14 are diagrams for explaining optimization of information storage in the field server device. Since the field server device 11 is installed in the field, the amount of information stored in the field is limited due to environmental limitations. Although the field storage information is premised on remote archiving, there is a risk that the field storage information may be lost due to various troubles (inability to communicate, remote server failure) at the archive stage. As a method to prevent this risk to the minimum, optimization of information storage is performed.

  As shown in FIG. 13, when the conventional information storage exceeds the limit of the storage space (storage space), the oldest information of the stored information is discarded and the latest information y1 is fetched. When the latest information y1 is stored, the information storage is moved sequentially from the first. As a result, in the storage space, the oldest stored information at the lowest position in the storage space is deleted at the timing (time, time, plant state change, etc.) of taking the latest information y1. However, it is impossible to reproduce the past plant information once lost.

  Therefore, as shown in FIG. 14, at the stage of fetching the latest information y1, the oldest information is not simply lost, but past plant information can be reproduced with optimization of stored information. The restoration of the past plant state is performed using the optimization section A to the optimization section C according to the restoration request level. As a result, field information can be managed for a long time, and stable information is provided to various systems using the field information.

In the example illustrated in FIG. 14, the field server device 11 performs a first process of sequentially storing input field information as storage information every minute in a general section. Next, the field server device 11 stores the information in the optimization interval A in order to change the stored information in every minute sequentially from the stored information in the first process to arbitrary stored information. Extract features from information. Next, the field server device 11 executes a second process for replacing the field information accumulated by the first process with the restoration information based on the extracted feature amount.
For example, in the optimization section A, one-hour average, maximum, minimum, etc. are accumulated as feature amount data.

  For the storage of information in the optimization section B, the field server device 11 extracts the feature amount of the information in the optimization section A from the one-hour storage information. For example, in the optimization section B, 8-hour average, maximum, minimum, etc. are accumulated as feature amount data. For the storage of information in the optimization section C, the field server device 11 extracts the feature amount of the information in the optimization section B from the 8-hour storage information. For example, 24-hour average, maximum, minimum, etc. are accumulated as feature amount data. The field server device 11 can reproduce past plant information using the feature data accumulated in the optimization sections A to C. With this configuration, more information can be stored in the same storage space.

  According to the cloud system of the present embodiment, even if the field server device 11 is out of order for delivery by e-mail from the field server device 11, it is automatically retransmitted after recovery and information loss can be prevented. In addition, e-mail is open in an internationally standardized format and can be easily constructed. Further, since the e-mail has both authentication functions and information is encrypted, a general-purpose low-speed digital line can be used. Simpler and more general hardware can be used than the conventional system. Long-term maintenance for the plant maintenance system is easily possible by using a general purpose. It can easily follow the evolution of general-purpose technology, and the latest technology can always be used.

  As mentioned above, although this invention was demonstrated using embodiment, it cannot be overemphasized that the technical scope of this invention is not limited to the range as described in the said embodiment. It will be apparent to those skilled in the art that various modifications or improvements can be added to the above-described embodiments. Further, it is apparent from the scope of the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention.
