一种矿用本安型自组网基站设计
A mine intrinsically safe AD hoc network base station design
摘要
Abstract
Aiming at the problem that the underground communication link of the mine is interrupted and the information of res-cuers cannot be exchanged after the disaster,a mine intrinsically safe AD hoc network base station is designed.Based on the SDR platform,the equipment adopts the scheme of FPGA + ADI AD9361+ intrinsic safety circuit,and uses wireless multi-hop,self-or-ganization and strong self-healing ability of wireless mesh network technology to quickly and conveniently form a wireless commu-nication network in the environment of underground power supply and communication system being destroyed,and at the same time,provides wireless coverage for terminal equipment such as handheld terminals,mine control balls,mine information recorders,etc.,to realize information exchange between the accident scene and the forward command.The test results show that the base station has the advantages of self-provided power supply,high safety factor,small size,light weight,small power consumption,etc.,2.4 GHz and 1.4 GHz dual-band wireless networking,multi-hop capability of 6-8 hops of video,single-hop transmission distance greater than 200 meters,single-hop transmission delay of less than 7 ms,power consumption of less than 15 W,and continuous work for 4.5 h,which can solve the communication problems encountered in the emergency rescue process of various accidents and disasters in mines.关键词
