The invention belongs to the technical field of inspection path planning, and particularly discloses a fire-fighting equipment intelligent inspection path planning method based on the Internet of Things, and the method comprises the steps: recognizing a passing fire-fighting hidden danger point, a track fixed deceleration point and a track state hidden danger point as target deceleration points; performing risk grading on each target deceleration point, matching a reference passing speed, and calculating an inspection task completion efficiency index and an inspection data quality index of each path; dynamically adjusting data quality index weights according to severity and marking time of hidden dangers in historical fire protection logs; and finally, based on the efficiency index, the quality index and the dynamic weight, calculating a comprehensive recommendation index through weighted fusion, and determining the path with the maximum index as a target inspection path. According to the invention, deep fusion of physical structure constraint, structure health state and fire-fighting hidden danger is realized, so that the data acquisition quality of a high-risk area can be ensured preferentially while the inspection efficiency is ensured.

This invention relates to a stent system comprising a covered stent and a delivery device. The covered stent includes a main stent, a semi-binding structure, and a branch stent. The lumen of the branch stent communicates with the lumen of the main stent. The main stent includes a main wavering coil and a main covering, with the main covering covering the main wavering coil. The semi-binding structure releasably binds the main stent to allow radial compression or release. The stent system also includes a pre-placed catheter extending within the lumen of the main stent, with its distal end extending through the branch stent. The stent system provided by this invention allows superselective guidewires to be inserted into branch vessels via the pre-placed catheter, reducing the difficulty of guidewire superselection and avoiding the problem of guidewire entanglement with the ultra-rigid guidewire of the main stent. This facilitates guidewire insertion into branch vessels, reduces surgical time, and lowers surgical difficulty.

This invention discloses a low-code data configuration and interaction method and system based on knowledge graphs, relating to the field of low-code platform technology. The method includes: performing entity-attribute data modeling for factory equipment to establish a functional graph; selecting the entities, attributes, and relationships to be displayed by the component using an entity-attribute-relationship designer, specifying the data display format, configuring data mapping relationships and display logic, and saving them to the component's JSON configuration; determining the selected built-in data request interface based on the attribute types selected in the component's JSON configuration, and executing data requests and echo operations; after the communication component completes the specified interaction action, it sends the data packet to the target component, whereby the target component temporarily overwrites its bound configuration attributes and re-requests and echoes data through the built-in data request interface, thus achieving component data replacement. This invention can reduce the difficulty of data configuration on low-code platforms and reduce the number of interface requests after page components complete data configuration.
