摘要： PROBLEM TO BE SOLVED: To manage and share the design information of facilities and equipments and to share design history information especially by the way of electronic management of facility history information by storing and managing the design history information added with the information on design change into a change difference information. SOLUTION: First, change data is sent to a database server and registered at the time of managing design change information. In the database server, a difference extracting part 21 checks change difference between data before change and data after change, and if the change difference exists, a design history information generating part 25 manages information about change such as change reason and the name of changing the design in addition to the extracted change difference information as design history information. Further, whether or not the change affects other designs is checked, when yes, the change information is send to related sections to support the maintenance of consistency of design data. A consistency checking part 23 checks the consistency among associated data, and the caution is given to a displaying part 28 when the consistence is not met.

摘要： PURPOSE:To perform an unmanned operation of a robot in a smooth and highly accurate way by avoiding automatically the interference between an obstacle and the robot, by replacing the obstacle having an environmental change with a fundamental form. CONSTITUTION:An obstacle 22 is first recognized by a visual device 9, and then a picture processor 10 calculates the maximum length of the pattern of the obstacle 22. This maximum length is supplied to an obstacle data file 11 of a computer 1 in the form of an input signal SIN3. The file 11 has the data on a globe having a diameter equal to said maximum length given as the signal SIN3. For the shunt control of the obstacle, the distance l between the center O of the globe 23 and a robot 24 is first calculated. Then l>r is satisfied when the radius of the globe 23 is referred to as (r). In such a way, an operation is possible in a simple way to shunt the obstacle 22. In this case, a changed locus is automatically produced with reference to an environmental model data base 4 which is under the control of a CPU2 which controls the file 11.

摘要： PROBLEM TO BE SOLVED: To improve precision in camera calibration for acquiring the internal parameter of a camera used for surveying in a stereoscopic method with a camera image.
SOLUTION: A reference scale 3 which is disposed in an envisioned objective measurement region and whose actual dimension value is known as well as a calibration pattern 2 are imaged with a camera from two imaging points. The position in an image coordinate system for each imaging point is detected from an image data. Then, a camera internal parameter 12a at that time point is used to acquire the position of each imaging point. The three-dimensional position of the reference scale 3 is calculated by a stereoscopic method to measure a dimensional measurement value of the reference scale 3. The error between the dimensional measurement value of the reference scale 3 and a known actual dimension value is used as an evaluation value, to judge whether the internal parameter 12a is optimum or not. If not optimum, the internal parameter 12a is so updated that the evaluation value becomes smaller, which process is repeated for optimum result.

摘要： PROBLEM TO BE SOLVED: To provide a calculation method of a voltage/power of an AC feeding circuit capable of calculating the voltage/power at each node of the feeding circuit in a state including a circuit constant of a three-phase power line at the receiving power side of the AC feeding circuit connecting two sets of single-phase ACs by three-phase-two-phase conversion for every feeding section.
SOLUTION: A nonlinear circuit equation is created based on a nonlinear equivalent circuit combining an equivalent circuit of the circuit equation and two-phase AC side feeding circuit based on the equivalent circuit of three-phase AC side with a train load positioning in the feeding circuit. The three-two-phase conversion part sets up the whole nonlinear circuit equation correlating the three-phase AC side circuit equation with the nonlinear circuit equation by a relational expression expressing the three-phase AC side current with a function of the two-phase AC side current having a coefficient of the relation of the conversion ratio between the three-phase AC side voltage and the two-phase AC side voltage. The voltage and power every time of each node of the three-phase AC side and the two-phase AC side are calculated by solving the whole nonlinear circuit equation.

摘要： PROBLEM TO BE SOLVED: To provide an assisting arrangement for generating a service power failure procedure capable of simulating a service power failure range using an existing CAD drawing, with no use of connection information between equipments generated based on the connection relationship on the drawing. SOLUTION: A charge/failure state discriminating part 14 discriminates a connection state between equipments from a geometric information of CAD symbol for an equipment in a CAD drawing displayed on a drawing display unit 11. The charge/failure state discriminating part 14 discriminates a charge/failure state of equipment from the discriminated connection state between equipments and the state of equipment extracted by an equipment state extracting part 13. A service failure procedure generating part 19 uses the CAD drawing to set operation for the equipment based on the discriminated charge/failure state for the equipment for specifying a service failure range.

摘要： PROBLEM TO BE SOLVED: To simplify description, a pre-processing such as check and input work of an original drawing and to exactly judge a connecting state between graphical factors. SOLUTION: A CAD-formed drawing in which state of system structure is expressed by using the graphical factors corresponding to each component of an object system is displayed (11). A boundary area as a closed area including all the graphical factors selected from the CAD-formed drawing is generated (12) by geometrical information of the selected graphical factors and preliminarily defined offset. The graphical factor a part of which is included in the generated boundary area is extracted as a connection candidate and the selected graphical factors and the extracted connection candidate are judged whether they are at the connecting state or not (14) by using restriction (13) for the CAD- formed drawing to be defined from semantics of the graphical factor corresponding to the extracted connection candidate.

摘要： PURPOSE:To provide a graphic approximate to the intention of a user in a short time even when strict applied by the user is exceeded or lacked by extracting an element, which can not unitarily fix the graphic due to the lack of the strict, an predicting the user intention. CONSTITUTION:Relation between the strict defined by the user and the element is analyzed, the element not to uniquely fix the graphic due to the lack of the strict is extracted, and the user intention is predicted from the graphic data of the element and the strict applied to the element. By converting the user intention to data to be handled by geometrical inference, the strict is complemented and inference is performed. For example, when a distance from a fixed point to a point P is applied for calculating the coordinate of remaining one point P while fixing the two apexes of a triangle, the point P can be positioned anywhere on the circle of a radius 100 around the fixed point and can not be uniguely fixed. Thus, the point P can be uniguely fixed by applying the prediction that the inclination of a line segment L is not changed when the strict is lacked.
