摘　　要：随着信息化技术的快速发展,人们对煤矿安全的要求越来越高。当发生危险时,及时对井下作业人员提供信息指导,将财产损失降到最低,是当前急需解决的问题。基于煤矿井下广播系统,提出了以NXP公司的LPC2378为主控制器的硬件设计,外围增加CAN收发器、以太网收发器来实现现场总线与工业以太网的互连,发挥了现场总线和工业以太网各自的优势,方便了管理人员对作业人员的指导,提高了煤矿生产的安全性。With the rapid development of information technology,people demand more and more on the coal mine safety. It is an urgent thing to provide information for the mine workers timely to escape and minimize the loss of property when a danger hap- pens. Based on mine broadcasting system, a new design is proposed in this paper. The main hardware consists of NXP＇s LPC2378 controller and peripheral CAN transceiver and Ethernet transceiver in order to make an interconnection of fieldbus and industrial Ethernet. The new design makes full use of fieldbus and industrial Ethernet respectively, and it is very convenient for mangers to guide the workers directly. It has great practical significance for raising the safety of the coal production.
