The invention discloses a reticular dimensional reinforced composite heat preservation rock wool board; the reticular dimensional reinforced composite heat preservation rock wool board is formed by combining a reticular dimensional reinforced rock wool heat preservation board with an organic heat preservation board in an adhering manner; the reticular dimensional reinforced rock wool heat preservation board comprises a rock wool layer, an upper reticular structure layer, a lower reticular structure layer and connecting pieces, wherein the upper and lower reticular structure layers are respectively arranged on the upper and lower surfaces of the rock wool layer, and the connecting pieces penetrate through the rock wool layer to connect the upper reticular structure layer with the lower reticular structure layer. The reticular dimensional reinforced composite heat preservation rock wool board provided by the invention can be applicable to regions with higher requirements on heat preservation and heat insulation; compared with the organic heat preservation board, the tensile strength and wind pressure resistant strength of a heat preservation system can be greatly improved; compared with a traditional rock wool heat preservation board, the thickness of the heat preservation system is effectively reduced, and the safety of the system structure is improved; meanwhile, the reticular dimensional reinforced rock wool heat preservation board on the surface can play the role of a fireproof barrier, so as to form an effective fireproof shield, so that the fireproof performance of the organic heat preservation board is greatly improved, and the fireproofing problem can be solved more radically by adopting the dual-composite mode.

The invention discloses a step counting method based on a triaxial accelerator, and relates to the field of sensor step counting methods. The real-time acceleration values of the triaxial accelerator on the x-axis, the y-axis and the z-axis are acquired, and the values of acceleration of the three direction axes are acquired; a sum acceleration value is calculated through the values of acceleration of the three direction axes; an actual acceleration value is calculated through the sum acceleration value; a preset positive threshold value and negative threshold value are compared through the actual acceleration value, and real-time motion state information is obtained; step state information is obtained by analyzing the real-time motion state information, and the step counting function is achieved. The step counting function can be achieved only through one sensor, namely, the triaxial accelerator, the advantages that the data acquiring speed is high, calculation is easy, convenient and high in efficiency, and the result accuracy is high are achieved, and good actual application and popularization value is achieved.
