Description

  The present invention relates to a maintenance information management system, a maintenance information management method, and a maintenance information management program.

  In process plants such as petroleum / petrochemical, chemical, and steel, facilities are managed using RMS (Remote Maintenance Support System). Here, RMS (hereinafter referred to as a remote service system) refers to a service that performs emergency maintenance, monitoring service, and the like using communication technology. For example, when a failure occurs in a process plant, failure information is collected remotely at a support center. As a result, failure information can be analyzed and accurate support can be provided to the site.

FIG. 7 is a configuration diagram showing an example of the remote service system 50.
The remote service system 50 includes a maintenance network 51, a maintenance target network 52, a maintenance target network 53, and a communication network N.

  The maintenance network 51 is a network in a service center that performs emergency maintenance, monitoring service and the like of each plant. The maintenance network 51 includes a maintenance terminal 54 and a communication device 55. The maintenance terminal 54 is composed of a PC (Personal Computer). The maintenance terminal 54 is used by an engineer waiting at the service center. An engineer standing by at the service center can use the maintenance terminal 54 to collect information on a failure that has occurred in each plant or to assist an engineer who has been on site.

  The communication device 55 relays data flowing on the network to another network. The communication device 55 is composed of, for example, a modem, a router, etc., and performs data communication between devices by Internet VPN or dial-up connection.

  The maintenance target networks 52 and 53 are networks in the plant factory to be subjected to emergency maintenance and monitoring. The maintenance target networks 52 and 53 include HMIs (Human Machine Interfaces) 56 and 57, communication devices 58 and 59, and a unit and the like (hereinafter referred to as plant diagnostic unit) for diagnosing the operating state and environmental data of the plant not shown. Configured.

  The HMIs 56 and 57 are composed of a PC. The HMIs 56 and 57 are connected to a plant diagnosis unit (not shown) through Ethernet. The HMIs 56 and 57 periodically acquire data regarding the operating state of the plant, environmental data, and the like from the plant diagnosis unit.

The communication devices 58 and 59 relay data flowing on the network to other networks. The communication devices 58 and 59 are constituted by, for example, a modem, a router, etc., and perform data communication between devices by Internet VPN or dial-up connection.

In the emergency maintenance work of the remote service system 50, an emergency maintenance function may be newly added or updated in order to strengthen the emergency maintenance function. An emergency maintenance function addition or update method performed in the remote service system 50 will be described with reference to FIG. Here, the emergency maintenance function refers to, for example, a program that collects diagnostic data on the operating state of the plant, a diagnostic algorithm, a data display program, and the like (hereinafter, the emergency maintenance function is referred to as maintenance information). The maintenance information is stored as a WEB application on the HMIs 56 and 57.

The method of adding or updating maintenance information is manually performed for all HMIs. Here, “manually performed” refers to adding or updating maintenance information by visiting the maintenance target networks 52 and 53.

As another method of adding or updating maintenance information, there is a method of setting a WEB site for addition or update (for update) on all HMI WEB applications. In this case, it is possible to add or update maintenance information without going to the maintenance target networks 52 and 53.

Further, a technique using a distributed file system that shares files on a plurality of computers on a network is known (see, for example, Patent Document 1).
JP 2000-76152 A

However, the method of adding or updating maintenance information performed in the remote service system 50 of FIG. 7 requires human labor until the addition or update of maintenance information is completed.
For example, when manually adding or updating maintenance information for all HMIs, the maintenance information must be added or updated by visiting the maintenance target networks 51 and 52. Therefore, it takes a lot of time and manpower to complete the addition or update of the maintenance information.
In addition, in the case of a method of installing an addition or update WEB site on all HMI WEB applications, it is not necessary to go to the maintenance target networks 52 and 53. However, it is necessary to connect to all the HMIs sequentially from the maintenance terminal and perform maintenance information addition or update operations. For this reason, it takes time to add or update maintenance information in proportion to the number of maintenance targets. Therefore, it takes human labor until the addition or update of the maintenance information is completed.

  The communication network N includes various communication lines such as a telephone line network, an ISDN line network, a dedicated line, a mobile communication network, a communication satellite line, and a CATV line network, and an Internet service provider base station that connects them.

Next, the emergency maintenance content file addition / update process of the remote service system 100 will be described with reference to FIGS. The addition / update of the emergency maintenance content file is performed when a new emergency maintenance content file is added / updated in order to enhance the emergency maintenance function of the remote service system 100. Hereinafter, an emergency maintenance content file addition / update process performed between the emergency maintenance content server 14 and the HMI 16 will be described.

First, an emergency maintenance content file addition / update process executed by the emergency maintenance content server 14 will be described. For example, it is assumed that the user gives an instruction to execute an emergency maintenance content file addition / update process via the input unit 24 of the maintenance terminal 13. Then, using the input instruction as a trigger, in the control means 31, the emergency maintenance content file is read out from the storage means 22 and loaded into the RAM as appropriate, and the emergency maintenance content file is updated in cooperation with the CPU. Addition / update processing is executed.

  First, the emergency maintenance content file is added / updated to the virtual directory of the storage means 32 of the emergency maintenance content server 14 through the operation of the maintenance terminal 13 by the user (step S10). Here, the virtual directory refers to a directory specified by a URL (Uniform Resource Locator). The addition / update of the emergency maintenance content file is realized, for example, by inserting a CD into a CD drive of the maintenance terminal 13 (not shown). In this case, the latest emergency maintenance content file added / updated is stored in the CD, and the emergency maintenance content file is added / updated by reading the latest emergency maintenance content file from the CD. Then, it is detected by the emergency maintenance content server 14 that the emergency maintenance content file has been added / updated (step S11).

  Next, the emergency maintenance content server 14 notifies the HMI 16 that an emergency maintenance content file has been added / updated, and a synchronization request is made (step S12). Here, the synchronization request refers to notifying the HMI 16 whether the added / updated emergency maintenance content file can be synchronized.

  Then, it is determined whether or not there is a reply to the synchronization request from the HMI 16 (step S13). When there is a reply to the synchronization request from the HMI 16 (step S13; YES), the added / updated emergency maintenance content file is transmitted to the HMI 16 (step S14).

  In step S13, when there is no reply to the synchronization request from the HMI 16 (step S13; NO), it is determined whether or not movement confirmation has been made (step S16). Here, the movement confirmation refers to an operation for confirming that the emergency maintenance content server 14 can transmit a synchronization request to the HMI 16. The movement confirmation is performed by transmitting a movement confirmation signal to the HMI 16 and confirming whether or not there is a reply. Also, the movement confirmation is performed with a smaller communication volume than the synchronization request. When the movement confirmation cannot be performed (step S16; NO), the interval for performing the movement confirmation is extended (step S17). For example, when the first traffic check is performed at an interval of 1 minute, the time interval is changed such as an interval of 3 minutes and an interval of 10 minutes. The change of the time interval is changed, for example, when the movement confirmation cannot be performed even if the movement confirmation is performed a predetermined number of times. For example, when 10 rotations are confirmed at an interval of 1 minute but no movement is confirmed, the operation is shifted to an interval of 3 minutes. And it is discriminate | determined whether it is a timing which performs movement confirmation (step S18). If it is the timing of confirmation of movement (step S18; YES), the process proceeds to step S16. If it is not the timing of confirmation of movement (step S18; NO), the process proceeds to step S18. In step S16, when the traffic can be confirmed (step S16; YES), the process proceeds to step S12.

  After execution of step S14, the notification of completion of synchronization of the emergency maintenance content file transmitted from the HMI 16 is received (step S15). After the execution of step S15, the emergency maintenance content file addition / update process ends.

  Next, an emergency maintenance content file addition / update process executed by the HMI 16 will be described. For example, it is assumed that an emergency maintenance content file synchronization request is issued from the emergency maintenance content server 14. Then, triggered by the synchronization request or the like, the control means 41 cooperates with the CPU and the emergency maintenance content file addition / update program read from the storage means 42 and appropriately expanded in the RAM. Emergency maintenance content file addition / update processing is executed.

  First, an emergency maintenance content file synchronization request is received from the emergency maintenance content server 14. Then, a reply to the synchronization request is transmitted to the emergency maintenance content server 14 (step S21). Then, the emergency maintenance content file for addition / update transmitted from the emergency maintenance content server 14 is downloaded (step S22). The downloaded emergency maintenance content file is stored in the storage means 42 (step S23). Then, the emergency maintenance content server 14 is notified that the synchronization of the emergency maintenance content file has been completed (step S24). After the execution of step S24, the emergency maintenance content file addition / update process ends. The emergency maintenance content file “emergency maintenance content — 001.aspx”, “emergency maintenance content — 002.asmx”, “emergency maintenance content — 003.aspx”, and “emergency maintenance content” are shown in FIG. “_004.asmx” stores the same content files in the emergency maintenance content server 14 and the HMIs 16 and 17.

  When deleting an emergency maintenance content file from the emergency maintenance content server 14, the same process as the above-described emergency maintenance content file addition / update process is performed. In this case, in step S14, the file name of the emergency maintenance content file to be deleted, the details of the deletion, and the like are transmitted to the HMI 16. In step S22, the emergency maintenance content file is deleted according to the information transmitted from the emergency maintenance content server 14 (the file name of the emergency maintenance content file to be deleted, the details of the deletion, etc.). Therefore, when deleting the emergency maintenance content file, the emergency maintenance content file is not downloaded in step S22.

  As described above, according to the present embodiment, the state of the latest emergency maintenance content file added, updated, or deleted can be reflected in the HMI 16. Therefore, it is possible to reduce artificial labor. In addition, the latest emergency maintenance content file can be centrally managed by the emergency maintenance content server 14, and management of the emergency maintenance content file over time becomes easy.

  The description in the above embodiment is an example of the maintenance information management system, the maintenance information management method, and the maintenance management program according to the present invention, and the present invention is not limited to this.

  For example, in the above embodiment, the emergency maintenance content file is added, updated, or deleted from the input unit 24 of the maintenance terminal 13, but may be configured to be performed from the input unit 34 of the emergency maintenance content server 14.

  In addition, the detailed structure and detailed operation of the remote service system 100 according to the present embodiment can be changed as appropriate without departing from the spirit of the present invention.
