Abstract:

The location card for mine underground position system based on WLAN is portable embedded device for mine workers,so it must satisfy the requirements of light weight,small volume,anti-interference and low power consumption.The paper discusses the design and implementation of location card from the aspects of both hardware and software,and puts forward some design methods for its non-functional requirements (anti-interference and low power consumption,etc.).

Key words: location card;WLAN;anti-interference;low power consumption
