Abstract: In view of problems existed in traditional laser coal stocktaking devices, a design scheme of laser coal stocktaking system based on embedded ARM and GPRS was proposed. In the system, embedded operation system μClinux and ARM7 series processor LPC2210 are taken as core of software and hardware, laser scanner is used to collect 3D information of surface of coal pile. The information are sent to GPRS module through serial port, then to server by Internet for further processing, volume and 3D graphics of the coal pile can be gotten at last. The testing result of experiment showed that the system has characteristics of convenient measurement and high precision.
