An object of the present invention is to provide an equipment state detecting device, an equipment state detecting method, and a program that can create a 3D model of a cable based on three-dimensional coordinates acquired using a laser scanner or the like, and precisely estimate the tension for the entirety of the cable even if the entirety of the cable is not three-dimensionally modeled in the cable model. An equipment state detecting device of the present invention creates a 3D model of a cable based on three-dimensional coordinates acquired using a laser scanner or the like, acquires a sag and a straight line connecting ends of the 3D model based on the 3D model, and calculates the tension of the cable using a known cable load per unit length.

Controllers that control a building's state functions can be controlled by a master controller that the controllers choose themselves. The master controller communicates with the controllers and sensors to determine when a building state should change. When the building state should change, the master controller or another controller determines the device or devices that need to modify state values of the building, and send messages to the devices so that they can change building state. If the master controller has a fault, the working controllers can choose another master controller. When a sensor indicates that a building state needs to be changed the master controller determines which device should change state, then tells the controller that is attached to the device.

An apparatus, method and the like which enables to represent a pipe network transporting a fluid by use of electrical circuit network is provided. The pipe network analysis apparatus includes; processing circuitry configured to receive a pipe network model that represents a pipe network being constituted by one or more piping elements, convert at least one piping element to an element of an electric circuit being configured to represent a non-linear relation between a pressure and a flow rate of the fluid in the piping elements by use of a relation between a voltage and a current, and generate a model representing an electric circuit network expressing the pipe network, by use of the element of the electric circuit; and an output device configured to provide the model analyzable by a specific electric circuit simulator.

A testing system and method are provided for verifying that a BIM-designed electrical distribution system in a building provides a valid, cost-effective electrical wiring pathway between every device and its assigned electrical distribution source. The system includes a digital processor having access to the informational content of the BIM-designed electrical distribution system, and a user interface and display screen connected to the digital processor. In operation, the digital processor extracts from the BIM-designed electrical distribution system the x-y locations of the devices, distribution sources such as electrical supply panels, and wiring pathway elements (e.g. conduits, junction boxes, etc.) forming electrical pathways. As the user lays out the pathways, the processor immediately informs the user, via the display screen, whether the distances between the device and the nearest exit point of the associated pathway and the distribution source and the nearest entry point of the associated pathway are within pre-selected, empirically-determined tolerances.

A two-dimensional drawing of a three-dimensional wire harness model is generated by selecting a starting node from a plurality of nodes of the three-dimensional wire harness model, where the starting node is directly connected to a first bundle and a second bundle of the plurality of bundles, wherein further each of the first and second bundles are representable by corresponding first and second vectors. A reference plane is defined based on an orientation of the starting node, the first vector and the second vector, such that a first adjacent node may then be mapped onto the reference plane by geometric translation. Thereafter, a plurality of mapping operations are sequentially carried out until each of the plurality of nodes and the plurality of bundles have been mapped, by geometric translation, to the reference plane, and wherein corresponding translation matrices are stored in association with corresponding ones of the plurality of mapped nodes and/or the plurality of mapped bundles. The two-dimensional drawing of the three-dimensional wire harness model may then be generated such that the two-dimensional drawing includes three-dimensional orientation data corresponding to the plurality of bundles.

A method for designing a system of electrical wirings for a complex system, in particular applicable to the design of electrical wirings of an aircraft, is provided. The electrical wirings allow the flow of digital, analog or discrete data between the components of the complex system and/or the transmission of electricity to components of the complex system, the components of the complex system being grouped together in subsystems, each able to perform a predetermined function, and able to be broken down into subsystems each capable of performing a predetermined sub-function. The wirings are distributed into functional groups such that all of the wirings allowing the flow of one or more data and/or the transmission of electricity, directly or indirectly necessary for the operation of the components of a subsystem, for performing the corresponding function or sub-function are distributed in a single and same functional group.

Tools and techniques are described to create a controller wiring board. A user, using a user interface associated with a controller, can determine which devices will be attached to a controller. The features of the devices may be already known by the controller. The controller can change wiring terminal types depending on the requirements of the devices wired to the controllers. In some embodiments, a device is wired to a module associated with the controller. The controller can signal to the module to modify its wiring terminal to match the needs of the device to be wired to that location.

Embodiments simulate a manufacturing resource including a cable by creating a polyline model of the cable that includes a collection of points. For each point, there is an associated point mass and zero mass sphere, and an assigned elasticity and torsional stiffness between the point and adjacent points. Position and orientation of a start point and an end point of the points is defined based upon position in three dimensional (3D) space of a manufacturing resource. In turn, a simulation of the cable for a time step is performed by computing forces on each point using: (i) the associated point mass, (ii) the associated zero mass sphere, (iii) the assigned elasticity and torsional stiffness between the point and adjacent points, and (iv) the defined position and orientation of the start point and end point. Performing the simulation determines position in 3D space of each point based on the computed forces.

In one or more embodiments, techniques are provided for modeling overhead line structures of electric railways that utilize a flexible, reusable structure template to automatically generate a 3D model of the overhead line structure. Each structure template includes a set of points that represent joints of the overhead line structure and components that represent elements of the overhead line structure. A feature definition of each joint and component includes properties, constraints and cell mappings. By mapping key points of reference lines for an overhead line structure to key points in an applicable structure templet for the overhead line structure, and applying the constraints and, in some cases the cell mappings, a 3D model of the overhead line structure is automatically generated. The 3D model may be a “low detail” stick representation for fast modeling, or, using the cell mappings, a “high detail” cell-based representation for very realistic modeling.
