According to the method, the blasting pollutant source item can be accurately inversed in real time, and the optimal ventilation strategy is dynamically generated according to the blasting pollutant source item, so that ventilation efficiency maximization and energy consumption minimization are realized, and construction safety is guaranteed.

This invention discloses a natural language interaction method for a construction safety AI assistant, belonging to the field of artificial intelligence interaction technology. It includes: receiving voice or text interaction requests input by construction personnel, processing the voice or text interaction requests to obtain standardized text requests; based on a pre-trained natural language processing model, performing intent recognition and entity extraction on the standardized text requests, outputting intent-entity association pairs; constructing a construction safety professional knowledge base, retrieving from the corresponding knowledge base according to the intent-entity association pairs, and generating natural language response content that conforms to the understanding of construction personnel; feeding back the generated response content to the construction personnel in voice or text form, while simultaneously recording the intent type, entity information, and response satisfaction of this interaction. This invention can accurately understand construction personnel's requests for safety procedure inquiries, operating specification inquiries, and training examinations, providing immediate and accurate intelligent responses.

The invention relates to the technical field of wallboard construction devices, and particularly discloses a metal plate wall rapid positioning and supporting device which comprises an assembly frame and a metal plate body, limiting abutting plates are fixedly connected to the two sides of the top end of the assembly frame, and abutting clamping plates are arranged on the sides, located on the limiting abutting plates, of the assembly frame; the two sides of the bottom end of the metal plate body are both located between the limiting abutting plate and the abutting clamping plate, the first transmission mechanism and the second transmission mechanism are independently arranged, clamping positioning and inner side supporting adjustment of the metal plate body can be achieved, and the supporting mechanism and the abutting clamping plate are arranged in a matched mode. Double fixation can be formed from the outer side clamping dimension and the inner side supporting dimension of the metal plate body, the installation stability of the metal plate body is guaranteed in an all-around mode, shaking and deviation in the construction process are effectively prevented, the positioning precision and the construction quality are improved, the whole device is compact in structure, positioning and supporting operation of the metal plate body can be rapidly completed, and the construction efficiency is greatly improved.

The invention belongs to the technical field of mechanical arm grabbing, and particularly relates to a building construction robot mechanical arm which comprises a mechanical arm body, and a grabbing mechanism is fixed to the output end face of a tail end joint of the mechanical arm body through a flange plate; the grabbing mechanism comprises a fixing plate fixed to the side, away from the output end face of the tail end joint of the mechanical arm body, of the flange plate, grabhook assemblies are rotationally assembled on the two sides of the bottom end of the fixing plate, an air cylinder is installed in the middle of the side, close to the grabhook assemblies, of the fixing plate, the driving end of the air cylinder is fixedly connected with a connecting plate, and the connecting plate is connected with a pressing plate through a compensation assembly. Through the grabhook assembly and the transmission assembly which are symmetrically arranged, synchronous opening and closing of the rotating plates on the two sides are achieved, meanwhile, friction force is increased by pressing the top of bagged cement through the pressing plate, and therefore dual limiting is formed, the safety and reliability of cement material grabbing and transferring are guaranteed, and material waste and construction potential safety hazards are reduced.
