A learning diagnostic system for a working machine is capable of making a fault diagnosis of the working machine universally relative to various types of sensor information, and preventing a failure in the working machine by enabling a fault diagnosis even in a transient operating state that represents a transitional state between operating states. A state learning devicesorts inputted sensor datainto one under a steady operating state and one under a transient operating state, and generates, through learning, steady state dataand intermediate state data, each including a permissible error. A state diagnostic deviceuses the steady state datato determine whether an operating state of the working machine related to the inputted sensor data is the steady operating state or the transient operating state, and make a fault determination in the steady operating state. The state diagnostic devicealso uses the intermediate state datato make a fault determination in the determined transient operating state. The intermediate state dataalso includes intermediate point information.

A progress status management device and a method for managing a progress status are provided so that a progress status of respective processes in a project is visually and swiftly confirmed. By using the device and method, it is possible to prevent a delay of the project progress because the processing states of processes at an optional stage of the project are shared and easily grasped by managers and workers among departments and outside business partners in charge of the project.

Progress status management method, program, and progress status management device

A business information management system includes a data connection relationship information storage section storing connection relationships of data items forming a business information database, a data connection accuracy information storage section that stores data connection accuracy between data item pairs having a connection relationship, and a data change section that changes data in the business information database by inputting data thereto. A change affected data extraction section extracts change affected data items by tracing first data items having a connection relationship with an originally changed data item and second data items having a connection relationship with the first data items until there is no connection relationship, a change effect probability calculation section calculates change effect probability of the change affected data based on data connection accuracy, and a change affected data display section displays the change effect probability on a display unit.

When an RFID is attached to an object to assist testing operations, the following problems are encountered; (1) the RFID of write type tends to cause a failure and is troublesome due to the necessity of rewrite each time the situation is changed, (2) the incorporation of the reader function in a terminal block increases the cost, and (3) the known techniques are targeted for only the connecting operation and are not adapted for a sequence test that takes the most expense in time and effort. The operations are aided by using an RFID reader and a terminal having the function for accessing a database of circuit information, RFID information, and test procedure information.

A scheduling system and a CAD system are used to prepare a construction plan in plant construction simulation. A construction work managed by the scheduling system and a plant part used in the construction work and managed by the CAD system, are managed in association with each other. When the plant part is broken down into a plurality of lower plant parts constituting the plant part, as a plurality of lower construction works of the construction work, the processing for associating the lower plant parts with the lower construction works is performed. Data for mutually associating the construction works and the plant parts based on the processing is generated. The generated data is used to mutually link the scheduling system and the CAD system, and a situation in which appropriate parts are installed as progress of the construction work, is displayed.

Disclosed is a cable identifying system for accurately discriminating one cable from another on site over a long period of time, the system enabling a cable layer or a cable user, when laying out an RFID built-in cable, to do without manually writing any information in the RFID tags built in the cable. One cable having RFID tags built therein can be accurately realized. The individual ID's of the RFID tags are read and stored in a storage apparatus. When a part of the cable is cut, the ID's of the RFID tags nearest to the both end of the cable are read out, and the ID-related data of the RFID tags in the cut-out cable are recorded on a desired medium or electronic information medium.

To support a tag information reader to read information from radio communication tags, attached to each of a plurality of structural objects in a plant and to provide the locations of unread radio communication tags, a tag information acquisition unit acquires information on radio communication tags actually read by the tag information reader. Next, an unread tag extraction unit extracts radio communication tags which are a plurality of radio communication tags stored in a tag arrangement data file but from which information cannot be acquired by the tag information acquisition unit, and an unread tag arrangement calculation unit acquires arrangement data on the extracted radio communication tags. The arrangement data on those radio communication tags is sent to a display unit for displaying the radio communication tags.
