To monitor the healthy status of the buildings, such as buildings and houses, it is necessary to collect the pressure information of these buildings. For the defects of traditional pressure information collection system, the paper designs a system to collect the pressure information of buildings. The presented system combines the IoT and CAN bus to improve the quality of collection. Our system sends...
A new approach of concentric circle detection is proposed in this paper. Firstly, the image is preprocessed by denosing, edge detection, and then the circle centers are allocated by the gradient Hough transform, at last, the radius are detected by the improved one-dimensional Hough transform. The detection efficiency is enhanced by image discretization and reduced resolution ratio in the process of...
The sensorless estimation principle of rotor speed and position for PMSM by high-frequency signal injection is given. The characteristic and filtering method of high-frequency current signal, rotor position signal extraction based on victor transformation and heterodyning processing method are introduced in detail. The simulation models are made, simulation results are obtained. The efficiency is...
After reform and opening-up, the China's Non-state owned economy grows rapidly. The Non-state owned economy not only becomes support in the growth of China's economy, but also makes a significant influence on increasing employment and promoting the transfer of labor in different industries and the employment structure's upgrade. In this paper, it sets forth the theoretical foundation of labor force...
Wireless communication system covers an entire region by dividing into many regions, and each one with a repeater. The Frequency Assignment Problem(FAP) requires that the same frequency should be shared by the repeater and the users, without being disturbed by other frequency of repeaters. The Conflict-Free Coloring problem is introduced to solve FAP that arises in wireless communication field. To...
