Abstract: A system and method for detecting elevator maintenance behaviors in an elevator hoistway. The system of the invention comprises: an emitting component for emitting wireless signals including channel state information (CSI) into the elevator hoistway; a receiving component for receiving the CSI from the elevator hoistway; and a maintenance behavior detecting device, which comprises: a memory that stores CIS image recognition models constructed corresponding to the predefined elevator maintenance behaviors and a corresponding computer program executable on a processor, and the processor configured to be able to execute the computer program to implement the following operations: processing data of the received CSI to obtain a CSI image corresponding to the elevator maintenance behavior detected, and inputting the CSI image to the CSI image recognition model for analysis and processing so as to detect the elevator maintenance behavior.

Abstract: A deployment method and deployment system for a wireless sensing device. The deployment method for a wireless sensing device includes S1: obtaining spatial structure information of a region to be deployed; S2: calculating a layout of the wireless sensing device; S3: calculating a signal strength according to the layout, and judging whether the signal strength meets requirements; S4: judging whether a default neural network model meets the requirements according to signals received by the wireless sensing device; if the requirements are not met, optimizing a pre-trained neural network model through transfer learning according to the signals received by the wireless sensing device; and S5: deploying the optimized neural network model into the wireless sensing device.

Abstract: A method of operating an activity recognition system includes capturing ambient radio frequency (RF) data by an RF sniffer. The ambient RF data is then received by a processor. The processor reduces noise content of the ambient RF data. Background is then subtracted from the ambient RF data by the processor. The processed ambient RF data is then converted into an image by the processor. The system generates successive images for each one of a plurality of time intervals. An image processing algorithm, stored in a storage medium and executed by the processor, is applied to the plurality of successive images to determine activity recognition.

Abstract: The present invention relates to a building management system based on identifiable marks that are arranged on terminal devices of a building and have a one-to-one correspondence with the terminal devices' own codes, the building management system comprising a user terminal, and the user terminal storing a database comprising codes of the terminal devices and comprising a scanning device for identifying and determining the identifiable marks, wherein an actual or relative location of the user terminal in the building can be determined by identifying and determining at least two identifiable marks. Moreover, the present invention further relates to an implementation method for the building management system based on identifiable marks. The building management system based on identifiable marks according to the present invention favors building management and the design, installation, debugging, management, and maintenance of terminal devices.
