Abstract: In order to obtain timely the location and speed information of the monorail vehicles for forest fruits, a new method based on GPRS wireless communication technology was introduced in this paper. Embedded processor ARM9 was selected as the core processor of both on-board controller and the remote ground controller. A rotary encoder was used for providing the location and initial speed information of monorail vehicles. GPRS technology was applied to accomplish wireless data transmission and control. Software and hardware design of the method was discussed, the wireless transmission time was tested and suggestions for improvements were proposed.
