According to the characteristics of broad frequency and abundant spectral components of mine microseismic signal, we use AR model parameters and BP neural network to propose a method of filtering treatment for the signal and noise with different frequency ranges. We can use this method to separate noise and signal, and decompose different frequency band signals, so we can achieve the goal of filtering...
With the development and application of modern science and technology, many new technical measurement methods have been put forward successively which are of high resolution and high collection rate about microseismic monitoring. We urgently need an effective detection method of abnormal data (mine earthquake) to collect lots of data to make real-time detection. In the past, we usually depend on experienced...
UDT is an application level, end-to-end, unicast, reliable, connection-oriented streaming data transfer protocol. The UDT protocol is completely at user space above UDP. For it bases on the implementation of UDP, so its real-time characteristic performs very well. In the user space, by designing a new congestion control algorithm, also a new mechanism dealing with the packet loss, UDT has enhanced...
Microseismic monitoring means to records microseismic activities caused by the changes of the rock physical properties continuously through the high sensitivity seismic sensor placed in mine. How to make real-time detection of abnormal data in mine microseisms positioning system is a extremely important task. Forecast model and mechanism of data stream in the mine microcosmic monitoring system are...
In order to meet the requirements of remote and high-speed data transmission, a remote communication system based on the analysis of existing communications facilities in mine, by using transmission network composed of PABX and Internet transfer controls programming, establish a link between mine micro seismic monitoring system and computer control center on the ground. And a special problem about...
