Abstract: With ARM Cortex-M3 kernel micro-controller, the multiple protocol communication platform of mine automation system is designed and implemented. The system architecture consists of micro-controller, real-time operating system and embedded TCP/IP protocol stack. With graphic display interface, TFT-LCD is driven by the SPI interface. After JPEG compression, the size of the image file is about 45 kB, and it needs about 600 ms transmission time, which can meet the requirements of communication platform. In order to improve the stability of the power supply, some technical measures are adopted to reduce noise and prevent interference. In order to facilitate the system debugging, RS232 serial communication is provided for PC to establish data connection, which can support technicians to observe the running state of the system with a portable computer or PC. Through RS232-485 converter, mine automation system equipment access can be realized. By porting the embedded TCP/IP protocol stack and embedded file system EFSL, file transmission and embedded Web server are both implemented. Basic information of the mine equipment can be displayed on real-time.The experimental results show that,through the integrated design of the mine automation communication platform, coordination and correlation operation of each subsystem can be realized, and the information-island problem in mines for years can be avoided. Seamless integration of the data collected from the whole mine is achieved on the Web, which can search and track all the dynamic information of stope environment changes and production process in a fast and real-time manner, monitor mine operation and decision-making in real time, command mine production and operation, trace accidents and make early warnings.
