ABSTRACT：In recent years, some large and medium-sized mines, belt conveyors in the country has adopted advanced automatic control technology and monitoring methods. This paper specifically describes the underground conveyor automatic control system hardware and software design. This paper was originally from the current development conveyor, focusing on monitoring and protection and technological innovation essentials of various types of conveyors, described the monitoring system and a variety of protected contact and hardware design ideas, to build the entire structure of the system and introduced the various functions of the system hardware modules. Paper describes the anti-deviation protection, anti-slip protection belt conveyor, ripstop protection, smoke temperature alarm fire extinguishing system unit, coal heap protection, belt protection, backstop protection, protection along fly zone protection. Paper gives a automatic tensioning device, belt deviation and improve the design of measures. PLC control methods to achieve the two electric motors on the underground conveyor for automatic control system to improve the security of the system.

Key words: belt conveyor, control systems, protection systems, plc programmable controller,  beltprotection

1.1 带式输送机的控制技术

当今随着长距离，大运输量输送机应用在井下原煤运输上，多点驱动和多机联合运转方式非常普及。随着矿井运输带化的推广，输送机逐步向采区内部延伸，其检测保护装置越来越多，也越来越先进。带式输送机可编程控制器PLC可用于整个运输系统的监测、控制、检测、扫描、纠错，以及胶带沿线的保护装置和设备之间进行网络通信信号的联络。如图1-1PLC框架图所示：
