【摘要】 我国是一个矿产资源丰富的国家，采矿业在国民经济中占有一定的比重。然而，矿井安全生产形势却一直不容乐观。建设现代化的高产高效的矿井，彻底改变我国煤矿行业的落后面貌已经成为当务之急。现有矿井监控系统大多设备单一，分布在各个部门，形成诸多的“信息孤岛”，不利于矿井安全生产的统一调度指挥，以及形成相关科室一览无遗的集成化矿井安全生产调度综合信息平台。矿井综合安全监控系统针对上述问题提出了一种集矿井环境监控、生产监控和机车运输监控为一体的综合信息系统。 本文将现场总线技术引入矿井综合安全监控系统，论述了基于CAN(Controller Area Network)的矿井综合安全监控系统的设计与实现。本文对CAN协议及其原理进行了研究，并根据系统需求自行设计了系统智能节点、中继器和总线转换网桥，制定了应用层通信协议。在通信中，提出了增加一个字节校验和以及端端差错控制的通讯机制，提高了系统通信的可靠性；采用了帧滤波措施，提高了系统的实时性。 为了提高本系统应用软件的通用性，论文对矿井综合安全监控系统的共性进行了抽象，提出了监控组态软件的整体结构以及系统主要功能模块的设计规划。通过系统在矿井机车运输监控系统中的实验性应用，论述了系统软件和硬件的通用性，可以推广到不同规模的矿井安全生产场合。更多还原

【Abstract】 China is a resourceful country of ore, and mining takes an important proportion of our country economy. However, the safety accidents of mine often occur and limit the improvement of productivity. How to construct the productive, efficient and up-to-date mine, becomes the ultimate way to change the undeveloped actuality. The existing mine safety supervise and control system which only watch part of devices and sensors in mine, is installed in isolated department, and come into being lots of "Information Islands" , which is not in favor of constructing a uniform control center to conduct the safety production of mine, and forming a integrated information platform to make the interrelated department scan the information of mine easily. To solve the problem discussed above, the mine synthesized safety supervise and control system tries to construct a synthesized system which can supervise and control the environment of mine, the production of mine and the transport of locomotive at the same time.The dissertation introduced the fieldbus, then discussed the design and research of the mine synthesized safety supervise and control system based on CAN. According to the research of the protocol and principle of CAN, the author designed the intelligent note, repeater and fieldbus switch, and set down the communication protocol of user layer. To improve the reliability of communication, the rule of point-to-point error control and the addition of a byte of check sum are introduced into the system. And to improve the real-time performance, the system applied the method of frame filter.To improve the reusability of the system, the dissertation presented the configuration model based on the abstraction of the objects of the mine synthesized safety supervise and control system and marked out the major modules of the system. According to the experimental application in mine locomotive transport supervise and control system, the dissertation shows that the system is flexible in the architecture of software and hardware, and can be easily extened to other mine safety production fields.更多还原
