【摘要】 煤矿安全现今已成为社会关注的热点,近几年,我国各地的煤矿事故频发,据官方公布的数据显示,2007年因煤矿事故而死亡的人数达3786人,令人触目惊心。而我国目前除了上级主管部门定期监察之外,缺乏更有效的安全监管措施。一些中小煤矿往往是为了应付检查,其监控设备形同虚设,存在严重的安全隐患。而且煤矿的生产环境十分恶劣,存在一氧化碳、瓦斯、二氧化氮、二氧化硫、粉尘等多种有害物质,严重威胁着矿工的生命安全,加强对煤矿的安全监控刻不容缓。基于这样的现实,本文设计了一种可以将现场监控数据通过网络上传到监管部门的嵌入式网络终端设备,实现了对中小煤矿安全生产的实时监控。本文所设计的嵌入式网络终端选用了高性能、低价位的S3C4510B微处理器,该处理器外配一个以太网接口芯片即可实现以太网接入;选用了扩展性强的独立CAN控制器SJA1000,可在10km范围内挂接110个具有CAN总线接口的现场监控设备,实现现场监控数据的远传;操作系统选用了uClinux,该嵌入式操作系统具备完整的TCP/IP协议栈,为应用程序设计带来了方便。本文完成了嵌入式网络终端的硬件电路设计,实现了uClinux嵌入式操作系统在S3C4510B上的编译和移植,设计了接口设备的驱动程序、服务端和客户端的应用程序。经测试,实现了CAN总线网络与以太网之间的透明数据传输,达到了远程实时监控中小煤矿安全生产的目的。更多还原

【Abstract】 The security problem of coal mine has become the focus which the society pays attention to nowadays. In recent years, our country has the coal mine accidents frequently around. According to data report which official announces, the number of deaths caused by the coal mine accidents amounts to 3,786 unexpectedly in 2007. However, our country lacks more effective safety ward precautions, besides supervised regularly by superior departments now. Some small and medium-sized coal mine have serious security risks, and their monitoring equipment is no use but only to meet the inspection. More attention, the coal mine’s environment existing many kinds of harmful substances such as carbon monoxide, gas, nitrogen dioxide, sulfur dioxide, dust, is very bad and do much damage to the lives and safety of miners. There is no time to delay to strengthen coal mine security monitoring. This article has designed an embedded network terminal which can upload the scene monitoring data to the regulatory departments through network, and has implemented the security production’s real-time monitoring of the small and medium-sized coal mine based on such reality.The embedded network terminal which this article has designed has implemented the Ethernet access with an Ethernet interface chip by using a S3C4510B microprocessor of high-performance and low-cost. It can hang up 110 scene monitoring equipments with CAN bus interface within 10km, and can implement the remote transmission of scene monitoring data by using an independent CAN controller SJA1000 of strong extended capacity. It adopts uClinux embedded operating system with complete TCP/IP protocol stack, and has brought much convenient to application design.This article has completed the hardware circuit design of embedded network terminal, and has implemented the compiler and transplantation of uClinux embedded operating system on S3C4510B. It has designed the driver program of interface device、server and client applications also. According to the test, it has already implemented transparent transmission between the CAN bus network and Ethernet, and has achieved the purpose which can remotely and real-time monitor the security production of the small and medium-sized coal mine.更多还原
