The invention provides a vascular plaque composition recognition method (300) based on a multi-contrast magnetic resonance image. The method comprises the following steps: implementing composition labeling (S310) on the to-be-trained multi-contrast vascular plaque magnetic resonance image; inputting the labeled multi-contrast vascular plaque magnetic resonance image into a convolutional neural network and implementing network model training (S320); and inputting the to-be-recognized multi-contrast vascular plaque magnetic resonance image into a trained network model and predicting the image, so as to output a vascular plaque composition recognition result (S330). According to the vascular plaque composition recognition method, the multi-contrast vascular plaque magnetic resonance image undergoes learning and modeling via the convolutional neural network, so that a new sample can be effectively recognized to assist a doctor in a diagnosis process, and working efficiency of the doctor can be greatly improved. The technical scheme can be conveniently promoted to magnetic resonance image assisted diagnosis processes of other organs.

The invention discloses a design standard review-oriented IFC data model building method. The method specifically comprises the following processes of extracting an entity object, an attribute constraint and a correlation relationship defined in a design standard clause, and establishing a standard clause system; comparing the standard clause system with an entity object, an attribute constraint and a correlation relationship defined in an IFC standard, and extracting and recording parts undefined in the IFC standard according to a comparison result to serve as extended standard information inthe IFC standard; selecting a corresponding IFC model extension mechanism, and establishing a design standard review-based IFC data model framework; and mapping specific data information in an obtained three-dimensional model to the established design standard review-based IFC data model framework, thereby enabling an IFC data model to completely express the information required for design standard review. The data exchange problem existent in drawing review in a BIM mode is solved.

The invention discloses a simulation resource data processing and controlling system for virtual tests, and relates to a simulation resource data processing and controlling system. The simulation resource data processing and controlling system aims to solve the problem of strict limitation on the universality and the openness of an existing simulation resource data managing system. The simulation resource data processing and controlling system comprises a first-layer organizational structure, a second-layer organizational structure, a third-layer organizational structure and a fourth-layer organizational structure; the first-layer organizational structure is used for storing simulation resource information by the aid of N database servers, the N is a positive integer, and each database server can process the original information in an optional form; the second-layer organizational structure is used for organizing data and serving simulation resource warehouses; the third-layer organizational structure is user application oriented and is used for implementing functions of warehouse managers in browser / server modes; and the fourth-layer organizational structure is used for external access including that users directly call or access service of the simulation resource warehouses and directly access warehouse management servers which are in website forms. The simulation resource data processing and controlling system is applicable to calling the simulation resource data of the virtual tests.

The invention, which belongs to the technical field of the automobile safety accessories, discloses an alarm device of a safety belt. The alarm device comprises a retractor, a safety belt braided belt, a safety belt lock assembly and a safety belt reminder. The safety belt lock assembly includes a slot and a buckle. The safety belt reminder consists of a pressure sensor, a signal detection device, a controller and an alarm device; and the signal detection device is used for detecting the stretched length of the safety belt braided belt. A key tooth notch of a buckle profile part and a protruded or recessed elastic part inside the slot are complementary. With the alarm device, a behavior that a driver deceives an alarm device by selecting another buckle to buckle it into a seat based on universality of the traditional buckle or enabling a safety belt to pass through the space between the back of a passenger and the seat and to be inserted into a safety belt slot can be improved; a phenomenon that a slot is blocked because of entrance of impurities into the safety belt slot opening can be avoided; and accidental shedding of the safety buckle can be prevented. Moreover, the alarm device has advantages of simple and unique structure, uniqueness, low mutual unlocking rate, low manufacturing cost, high security, reliability, and practicability, and easy popularization and application.
