Research On Environment Perception System Of Underground Transportation In High Altitude Mine Based On Multi-source Information Fusion

In recent years,the mining depth of mineral resources in plain areas has been increasing year by year,making mining more difficult.Meanwhile,with the further promotion of "One Belt And One Road" construction in China,it is imperative to vigorously exploit high-altitude mines in order to guarantee the supply of mineral resources for national production.Paper to high altitude mining underground transportation environment as the research object,in order to reduce the risk of accidents and to ensure the safety of transportation,for the purpose of the research on the basis of a large number of literature,through the indoor model test and theoretical analysis,methods of building,in high altitude mining underground transportation environment risk perception technology research,the main research results are as follows:(1)To explore the importance of environment in the whole transportation system of transportation,based on the accident cause theory,through the high altitude typical accident statistic analysis of underground trackless transport from people's unsafe behavior and unsafe state of transportation equipment,environmental unsafe factors,transport material and the defects of safety management five aspects comprehensive expounds the influence factors of high altitude underground trackless transport accident and the specific form of expression,on the basis of constructing the high altitude mines underground trackless transport risk index system,through the analytic hierarchy process(ahp),the study calculated the index weight,The calculation shows that the weight value of environmental insecurity factors is second only to the defect of safety management.(2)To realize real-time comprehensive transportation environment perception,studied the embedded development board,gas sensor,a mechanical sensor,a vibrating string type sensor readout module,wireless transmission module,power supply module hardware working principle and performance indexes such as,selecting the suitable for high altitude mining at low temperature,low pressure environment of hardware module,developed the "device" high altitude mining underground transportation environment perception;Based on the Lab VIEW virtual instrument technology and control theory of multi-sensor developed "high altitude mining underground transportation environment perception device" software control program,realized the configuration and debugging of multi-types sensors,data storage and playback function,through the research and development of hardware and software development,established the high altitude underground transportation environment perception system.In the process of system development,two adaptability tests of high-altitude environment simulation cabin and one routine indoor test were carried out,and the test results showed that the performance of the developed "high-altitude mine underground transportation environment perception system" was stable,met the design requirements and could be applicable to the alpine environment.(3)Based on the multi-source information fusion technology,selection of primary adaptive weighted data fusion algorithm and secondary BP neural network data fusion algorithm used in high altitude mining underground transportation environment perception system,multisensor data by information fusion and scientific and reasonable comprehensive treatment,after compared with the actual situation,show that this method can effectively determine the high altitude underground transportation environment security,improve the intellectualized degree of risk perception diagnosis.Theory with practice,the paper constructed based on information fusion technology "high altitude mining underground transportation environment perception system" can apply to high altitude mining environment,the comprehensive accurate perception of high altitude environmental risk in transporting underground parameters change,and through the information fusion significantly improved the high altitude veracity and reliability of mine safety assessment of underground transportation environment,intelligent,for high altitude mining underground transportation security play an important role.
