　　移动机器人由于具有优越的机动性和灵活性而备受青睐,在许多场合投入实际应用,如核工业检测,消防、火场检测,有毒、易燃、易爆气体场所探测,采矿、星球探测及无人战场等。为了适应不同环境下的应用,移动机器人控制系统的硬件和软件结构也不相同。本文涉及到的移动机器人是应用在防爆系统中,控制系统要求高稳定性、可靠性和实时性,采用西门子的S7-200系列的PLC作为控制器对其进行控制是一种既经济又能充分满足设计要求的有效方法。

1 移动机器人控制系统的硬件设计

1.1 控制系统组成及PLC控制原理

　　一般的控制系统采用工控机控制整个系统的工作,工控机工作可靠、控制准确、使用方便。防爆机器人一般工作在室外环境和野外环境,工作环境恶劣。作为移动机器人,整个控制系统要求尽量轻便,这时若采用工控机则整个系统不够方便、灵活。PLC具有良好的稳定性、结构轻巧,采用两个PLC作为上、下位机,则系统轻巧灵活。根据操作和控制要求,控制系统选用西门子公司的S7-200系列的PLC,该PLC可以满足多种多样的自动化控制需要。由于具有紧凑的设计、良好的扩展性、低廉的价格以及强大功能的指令,使得整个控制系统的性价比大大提高,操作也简单易行;同时,系统的可靠性、稳定性和控制的准确性也得到了保证。控制系统结构如图1所示。

　　Propulsion Laboratory, a contractor of the U.S. National Aeronautics & Space Administration), Dr. Fymat was actively engaged in atmospheric sciences, the environment, climatology, and space exploration. He was an investigator in several Earth- and space-based experiments within the U.S. Earth and space exploration program. He was an Advisor to the U.S. National Research Council, National Academy of Sciences for its post-doctoral programs tenable at the Jet Propulsion Laboratory. His industrial experience was in the context of the U.S. Strategic Defense Initiative (Ballistic Missile Defense Program) researching and designing atmospheric probes and electromagnetic sensors operating in benign and stressful nuclear environments. Dr. Fymat’s current research interests lie at the interface between science and medicine (particularly molecular/personal/precision medicine, nanomedicine, nanotechnology, and human genetics/epigenetics/ecogenetics), He has extensively published (about 350 scholarly publications including patents, books & monographs, book chapters, refereed articles). He has received numerous research grants from government, academia and private industry, and has consulted extensively with these entities. He has lectured extensively in several national and international academic, professional, governmental and industrial venues. He is Honorable Editor of the “International Journal of Cancer Prevention & Current Research” and the
