Research and Application of Digital 3D Modeling Technology in Substation Monitoring

Abstract: The security of the substation is the top priority in the electric power system. This paper researches 3D spatial modeling in the substation through the spatial data acquired by the terrestrial 3D laser scanner. This paper first discusses the impact of the point on the data acquisition and then stitches and registers the original measurement data through the whole match and correction, and finally establishes a 3D surface model. The research shows that, 3D laser scanning technology can be used to quickly construct a 3D spatial visualization model and solve deficiencies of the traditional measuring instruments and measuring methods in the substation and other special fields. In order to be able to realize digitalization of the substation resources, this paper provides a new direction for the construction of a 3D model in the substation.

An on-line data acquisition system based on a NORSK DATA ND-100 computer

Abstract: This paper describes a data acquisition system based on CAMAC for an ND-100 computer in a multiparameter environment. It consists of several real-time tasks which share common data and are synchronised to acquire events, record on magnetic tape, perform on-line analysis and permit display of one- and two-dimensional graphs so generated.

A real-time data acquisition system for the Laguna Verde nuclear power plant

Abstract: This paper focuses on a Data Acquisition Real-Time System developed for the Laguna Verde Nuclear Power Plant in Veracruz, Mexico. Due to the fact that the data acquisition modules needed to be replaced, the need for a New Acquisition System arose. Replacing the former data acquisition system has several technical challenges, including the fact that it must work together with the former system. Additionally, it must remain online during the whole process, since the Data Acquisition System is one of the nuclear power plant most important monitoring systems and it is required for its operation. This paper focuses on the key software design aspects of the New Acquisition System, which were used to address the main system requirements: Integration with the former data system, multiple data source support, high-frequency data storage and high-speed data access. The New Acquisition System is composed of a vast number of modules. This paper specifically focuses on Acquisition Subsystems, the Central Acquisition Process and the Master Historical Archive Process.

General hyperspectral imaging component

Abstract: The invention discloses a general hyperspectral imaging component, comprising a C-Mount interface, a collimator, a dispersion unit, a converging mirror, CCD, a data acquisition and control module, communication cables and a computer. The invention has the following characteristics: the C-Mount interface, the collimator, the dispersion unit, the converging mirror and CCD are in light path connection in turn; the reflected light or the transmitted light of optical instruments is introduced to the collimator through the C-Mount interface, split in the dispersion unit and image on the CCD by the converging mirror. An output signal cable of the CCD is connected with the data acquisition and control module, a control cable of the data acquisition and control module is connected with the dispersion unit and the data acquisition and control module is also connected with the computer. By the control of the data acquisition and control module, the length of incident light is changed by the dispersion unit, the image data is collected by the CCD and the hyperspectral image data is obtained in visual field region of optical instruments. The invention can be coupled with common optical instruments to extend the utilization range of optical instruments.

Apparatus for and method of selecting material triplets for a multi-material decomposition

Abstract: An imaging system includes an x-ray source configured to emit a beam of x-rays toward an object to be imaged, a detector configured to receive x-rays that are attenuated by the object, a data acquisition system (DAS) operably coupled to the detector, and a computer operably coupled to the DAS. The computer is programmed to obtain scan data with two or more incident energy spectra, identify one or more material triplet combinations based on data obtained prior to obtaining the scan data, decompose the obtained scan data into three or more basis materials based on the identified one or more material triplet combinations, and generate an image using the decomposed scan data.
