Conclusion
In the past we design public infrastructure projects due to subway and light rail bottlenecks in communication technology subject. Only in accordance with local automation technology an integral part of the separate system. Now our communications technology has developed to a fiber optic system, Wi-Fi system, 4G system, completely solve the bottleneck of the key technologies of large data communications system traffic. So, we designed "digital intelligent mechatronics interconnection system design" with a "Wireless & Cellular Telecommunications Third Edition (US)" theory is based on an integrated dispatch control operator need information management, showing a network of digital mobile, operators of the new features of wisdom, through the establishment of large-scale information collection and information integration platform to do big data. The use of artificial intelligence, big data, networking, cloud computing and other new information technology software platform, integrating modern streetcar project security operations support system. More computing application of information technology in-depth development to the cloud. To establish a "central information management system" in the control centers collected a large number of modern buildings and tram security operations require security, stability, the whole point of time Comprehensive data traffic operations, extending the life of the modern trams security operating cycle time. We through the central information technology software for a variety of data classification, statistics, analysis integration, obtain safe, stable and efficient operation instruction, guide dispatchers through digital network management, truly reductions and efficiency, reduce operational and workload and maintenance costs, to avoid a large number of security risks and greatly reduce the economic cost of manufacturing operations. Suzhou New District Line 1 modern streetcar project in October 26, 2014 adopted a formal acceptance, operations a year. "Interoperability + digital intelligent integration of modern tram in the city of applied technology" design, to achieve an intelligent, comprehensive information line network integration. Software platform interoperability energy information management system to achieve real-time cloud computing open software system, the accumulation of the next big data integration and sustainable development, access to first-hand information. For the future implementation of the new mechanical and electrical equipment access, integration of intelligent energy-saving projects, ecological reduction, lean management can truly reductions and efficiency, making the modern tram transport dimension becomes more humane, more wisdom, simpler, more economical! "Interoperability + digital intelligent integration of modern trams in the city applied technology" makes intelligent mechatronics information systems more secure, stable and reliable. And leaders at all levels of the State Department of Transportation Secretary highly recognized and praised in the November 21, 2014. Suzhou Modern streetcar project was listed as the No. 1 model lines and establish a modern Chinese city tram interoperability information software platform and energy management systems for monitoring the success of the demonstration project.
