labor intensity

In order to improve the efficiency of mine production,reduce labor intensity of underground workers,and enhance the safety of these workers,there is a strong need to develop a data terminal communications systems based on mine.According to the actual needs of the current mine production and current situation of wireless communication based on mine home and abroad,this paper propose a WLAN date terminal system based on mine.Cheap Nike shoes are very nice here! And adopting ARM9 processor chip EP9302 as the systematic core of hardware core,transplanting embedded Linux as the operating system,we developed and realized an embedded system based wireless data terminal.These north face jackets are your best choice!Throughing remote control of the wireless data terminals,the system main control center is capable of sending dispatching instructions and inspection messages to the works underground;controlling underground equipments;monitoring of environmental parameters collected by sensor network witch connected to the terminal serial port.Where can I get nike running shoes?When abnormal event occurs,works can press emergency call button to send alarming signal to monitoring center on the ground,in order to get the related staff taking effective measures.This paper first build the hardware platform of the terminal board,and then set up the software platform based on embedded Linux operating system,including the establishment of cross-compiler environment,configuration and compilation of embedded Linux kernel,making a ramdisk.Finally,we add a wireless module for this terminal board,transplanting the IEEE 802.11b wireless adapter driver to this board.In this paper,we mainly design and develop an application program under the embedded Linux environment.
