| Abstract: | Traditional positioning device,which can not work in remote area,only works under the premise that GPS or mobile phone signal can cover.In this paper,a positioning device which is independent of GPS based on Fujitsu MB95F204K SCM and ZCC212N-232 electronic compass is designed.In this system,reflective optical sensor is used to collect walking signals.Electronic compass communicates with SCM in the way of RS-232 and sends real time absolute angle to SCM.SCM calculates the increment of coordinate through the expansion formula of trigonometric function,then we can draw the track on screen.The practical application of the positioning device shows that this positioning device is low-powe-consumption,portable,plantable and has high precision. |
