摘要： PURPOSE:To securely and easily shift a rule set by generating shift order information on the rule set in a first rule set and sequentially shifting information to other rule sets in using the information as an argument. CONSTITUTION:A rule set A contains a rule for generating the arrangement of the rule sets and the arrangement [BCDC] of the rule sets, which comes to shift order information on the rule sets, is generated from an inference result using the rule set A. When the applied rule is eliminated or a prescribed condition is satisfied in inference in the rule set A, shift in which a rule set B being the head of arrangement information on the rule sets is set to be a shift destination rule set is executed, second and succceeding and arrangement information on the rule sets [CDC] are transferred to the rule set B as the argument. Such shift is repeated until data on the argument is eliminated. Thus, the shift of the rule sets can securely and easily be executed.

摘要： PURPOSE:To freely realign a sequence and to automatically form an operating sequence merely by adding or altering facility information at the time of increasing new facility by setting a concept key of a switch type, an operating direction, etc., and combining the operating sequence and a plurality of concept keys. CONSTITUTION:A knowledge base 1 stores information for forming an operating sequence, a power facility information unit 1a expresses facility of a generating substation, switches, connecting relation of the facility in a frame structure, and sequence table forming logic information unit 1b expresses knowledge for forming sequence in a production rule. An inferring mechanism 2 refers to information of the base 1 to inter forward, and outputs the sequence to a working area 3. The area 3 is an area used by the mechanism 2, and outputs the sequence. The information in which individual sequences are summarized in knowledge concept is reserved, and the sequences are freely realigned by referring to a group of the sequences by the expression of various levels.

摘要： PURPOSE:To facilitate the changing of screen data so as to reduce its amount by keeping only a sheet of total system picture plane data in a screen data bank and cutting out a region, specified from this data, to display a total system screen and divided screens. CONSTITUTION:A screen data bank 4A keeps a sheet of total system screen data in which data of each equipment is combined. A screen name is inputted to a screen region, in which the left lower and right upper portions of a total system screen of the data bank 4A are position-specified, and registered being paired with a screen region data. Next, the screen name is registered as an attribute value thereof by specifying the reduction ratio for enlarging and reducing a display screen. In this way, in order to display divided screens, divided- screen display of specified region and reduction ratio is obtained by selecting the screen name on a menu from the next time.

摘要： PURPOSE:To improve the job efficiency of a data input by providing a data storage area maintenance function and a connector generation production rule and simultaneously inputting skeleton data and attribute data so as to automatically generate connection data at the time of selecting a display symbol. CONSTITUTION:single line connection graphic (skeleton) data and attribute data of equipment, a device, a switch LS1, a relay O1 a fault display unit are simultaneously inputted by selecting the skeleton display symbol on a display symbol list. Even if a man does not input data on the connection relation (connector) of equipment and the switch, the connector generation production rule of an expert system construction support tool automatically generates it based on skeleton data.

摘要： PURPOSE:To input a confirmation item procedure rule by an element of a minimum limit by composing the rule of a condition unit including a device operation, a device type, a command facility, etc., as factors, and an executing unit including states before and after an operation. CONSTITUTION:As command words, four words of 'stop', 'use', 'incorporate' 'release to incorporate' are set. A switch operates an incoming line CB, a bus Ls, etc., in combination with 'open' or 'input'. A command facility column distinguishes the line from the line CB. Similarly, since a switch operation 'to open the lime CB' is different in 'confirmation item procedure' in the cases of the 'stop' and 'the release to incorporate', 'a command word' is used as a factor. In order to distinguish a power line from a load line, 'facility operating method' is set. An executing unit has two executing factors to be inserted before and after 'key procedure' according to a searching result. Thus, the device operation familiar with a judging logic having no feeling of physical disorder can be performed.

摘要： PURPOSE:To constitute this system so that a production rule can be generated and changed easily, and also, errors are reduced by expanding to the combination of a simple syntax and a word by syntax/word data with an input and a change by the Japanese language at the time of generating and changing the production rule, and converting it to an inference engine language. CONSTITUTION:With respect to the conditional sentence and the execution sentence of an inputted and registered rule, for instance, the fundamental syntax of a condition 1 is expanded as a syntax 2, the syntax 2 is read intelligibly as the combination of a syntax 3 and 4, and as for the syntax 3, it is identified to have an unsubstituted word 2, and the word concerned 2 is read intelligibly as the combination of a word 3 and 4. Consequently, the condition 1 is expanded as the combination of the syntaxes 3, 4 and the words 3, 4 each syntax and word are converted to an inference engine language and the language of the condition 1 is obtained. Also, with regard to the condition 2 and the execution 1, as well, the same expansion is executed, and all the conditional sentences and execution sentences are converted and summarized to the inference engine language and registered as a rule 2 in a knowledge base. In such a manner, the production rule can be generated and changed easily and exactly.

摘要： PURPOSE:To secure the unity and the consistency of processing result output data without a centralized management mechanism by adding a priority to the output data from each computer unit in a decentralized power system monitoring control system composed of a plurality of computers. CONSTITUTION:An I/O unit 1 gives the data body a processing identifier and a priority in a processor 12 when it receives the power system data 5 with the input part 11. The output part 13 further let data flow to the I/O 21, 31, and n1 of a necessary processing unit out of processing units 2, 3, ...n through a communication path 6. The processing unit which has received output data adopts the data with the highest priority in case that there are plurality of data which have the same processing identifier. The unit concerned gives it the priority being given to the unit after processing it, and let it flow to other processing unit. By the above, the content common to all processing units can be made effective, and the unity and the consistency of the output data can be materialized without a centralized management mechanism.

摘要： PURPOSE:To construct a system having high performance, and to restrict the influence range of the fault even when a fault is generated by providing decentralized processing computers corresponding to respective functions and providing each computer with a processing program for attaining a function to be executed by the computer itself and data. CONSTITUTION:This system is provided with decentralized processing computers 1 to 4 and the number of computers is determined in accordance with the sizes and contents of functions to be processed by the system. The system is also provided with a communication line 5 for transmitting/receiving information among the computers 1 to 4, processing program groups 11, 21, 31, 41 and file groups 12, 22, 32, 42 required to attain subfunctions to be processed by respective computers 1 to 4, and so on. Thereby each of the computer 1 to 4 receives only input data through the communication line 5 at first, and after executing all necessary processing, outputs only the final output data. Consequently the system having high independency in respective decentralized processing computers 1 to 4 can be attained and the influence of a fault can be suppressed.
