基于plc的立体车库控制系统设计和实现.doc

摘 要 伴随着科技的进步。汽车的增多带来了诸多的社会问题，土地资源，停车难的问题日益凸显。立体车库立体车库解决城市停车难问题，满足不同层次用户的需求。硬件可靠、控制系统稳定、。本文 PLC立体车库控制系统。PLC和触摸屏。 PROFIBUS-DP现场总线通信网络，CPU315-2DP作为系统主站，触摸屏，输出输入单元和变频器通信网络的从站。系统以触摸屏。车库状态载车板升降的速度；车库输入输出设备ETM 上，将采集到的车库状态信号CPU，。PLC通过扩展模块换向机构，升降设备。主要是通过STEPPLC系统硬件网络的组态、总线和DP主从站的参数，站地址，。变频器和PLC通信程序。WinCC flexible软件。本文立体车库控制系统，实验室实物调试。 系统设计结构合理、存取车效率较高、。 关键字：立体车库；触摸屏；PLC控制系统 论文类型：应用研究 With the advancement of technology and the further development of auto industry, the level of social productive forces increased significantly, car gradually became an integral vehicle of peoples daily life. Increased car bring many prominent social problems, one of which is the contradiction between the shortages of land resources and rapidly increasing number of cars more and more serious. Parking problems become prominent increasingly. Stereo garage came into being in the environment. The establishment of stereo garage is an effective measure to solve the parking problem in the city. Depending on the size of market demand, stereo garage needs to diversify to meet the needs of users at different levels, so in-depth study of stereo garage, design hardware reliability, control systems stability, HMI interface friendly, storage and retrieval operation of the stereo garage easily is a very meaningful work. This paper analyzes the basic framework，structure and operation of the stereo garage, designs a stereo garage control system based on Siemens touch screen and PLC. The visibility of the touch screen and the stability of PLC meanwhile the compatibility between them are fully used in the control system. The whole control system apply PLC as core control equipment to control normal operation of the stereo garage, establishing a PROFEBUS-DP field bus communication networks, S7-300 series PLC CPU315-2DP as a master station of the communications network, touch screen MP270B，frequency converter MM440 and distribution type I/O devices ET200M as slave stations of communication network. Touch screen is
