In this paper, a mining automatic drainage monitoring and control system based on Siemens PLC is designed according to the actual situation of the central pump house of some coal mine. The specific principle of the automatic drainage monitoring and control system is introduced. The flow chart of the main system control program is given. The algorithm implementation of the of instantaneous and accumulative...
Capacity of a cognitive radio (CR) link is related to two external factors: (1) primary usage pattern; (2) interference of the CR nodes. In this paper, we proposed a novel routing metric named cognitive routing metric with improving capacity (CRM-IC) to capture the end-to-end throughput in heterogeneous network. Because of the heterogeneity of nodes, the calculation methods are different with homogeneous...
Virtual reality technology is widely used in indoor building walkthrough. As the limited capabilities with data volume and network transfer, 3D scenes on the Web have less photorealistic and interactive than stand-alone systems. This paper designs and implements a system for indoor virtual roaming. Its manipulating mechanism make scene with good interactivity. Moreover, powerful capabilities in data...
