Intelligent traffic management and evaluation system based on BIM

The invention discloses an intelligent traffic management and evaluation system based on BIM. The invention relates to the technical field of intelligent traffic, and aims to solve the technical problems that a traditional intelligent traffic management system cannot quickly acquire digital achievements of urban traffic design and construction and is inconvenient for complete-cycle and all-aroundinformation sharing of design, construction and management. The invention discloses an intelligent traffic management and evaluation system based on BIM. The system comprises an information collectionunit based on BIM, a control management unit and a display unit. The invention provides an intelligent traffic management and evaluation system based on BIM. The BIM technology can be utilized to realize full-cycle information sharing and operation supervision of urban traffic from design to construction and then to later operation maintenance management, thereby avoiding self-integration of eachprocess, isolating information, avoiding repeated collection requirements of the information, realizing smooth transmission of the information, and providing accurate data support for traffic managers.

High-temperature and large-range silicon-sapphire pressure sensor structure

The invention provides a high-temperature and large-range silicon-sapphire pressure sensor structure, which comprises a titanium alloy shell, two titanium alloy diaphragms, a connecting cylinder, a sapphire diaphragm, a monocrystalline silicon strain resistor and a metal wire. One titanium alloy diaphragm is combined with the sapphire diaphragm through vacuum sintering so as to form a sensitive element of a pressure sensor. A layer of monocrystalline silicon thin film with the thickness thereof to be 0.1-0.5 mum grows on the sapphire diaphragm in the heteroepitaxial manner. On an epitaxial film, the monocrystalline silicon strain resistor is prepared through the semiconductor plane process. The resistor forms a wheatstone bridge. The lower part of the other titanium alloy diaphragm is connected to a cylinder and the lower surface of the cylinder is provided with a spherical concave surface. The spherical concave surface completely fit the sapphire diaphragm during the deforming process. Meanwhile, the spherical concave surface is kept at a spacing of 5-10 mum from the sapphire diaphragm when there is no load. According to the technical scheme of the invention, upper and lower diaphragms form a separation type double-diaphragm structure. During the measurement process of a small-range pressure, the advantage of high sensitivity is realized. Meanwhile, the structure can be used for the measurement of large-range pressures.
