Development of the Internet has penetrated into every aspect of our lives, along with the cloud, big data and artificial intelligence popularity of technology and so on, every move we have no reservations show on the Internet, it is difficult to be absolutely safe and reliable. (Chen: 189-2212-1563 micro-electro same number) with "smart building" universal, building automation system is also widely used in important areas of civil hospitals, hotels, commercial complexes, subways, tunnels and airports . These applications involve a lot of equipment, management information, environmental information and personnel information, etc. Once infected virus or hacker attacks, the existing building automation system and security information storage system will instantly collapse.
It is based on the above considerations, Paul Swiss-controlled intelligent building as a rising star in the field of domestic, give full play to the advantages of linkage between schools and enterprises, with the East China University of Technology, Suzhou Industrial Technology Research Institute of East China University of strong automation control in the field of information technology and security advantages , combined with their experience in industrial applications, priority will "block chain technology" and "industrial-grade redundancy control technology" used in "building automation" in the field of intelligent building, to achieve industry-leading technological breakthroughs.
Paul-controlled Suzhou Electronic Technology Co. developed the "block chain technology based on programmable controllers redundant control data backup security" technology has been officially submitted to the State Patent Office, and formally accepted.
Redundant control system of FIG. 1 Schematic

Block chain is a new protocol to the center, which is associated with a series of cryptographic method of data blocks, each block contains its own data, for verifying the validity of the information and generating a region thereof Piece. The idea is redundancy by configuring multiple devices functionally equivalent, through some redundant logic so that they coordinate synchronous operation, to ensure the security of the system application function to achieve and improve its reliability.
Given the current redundant control of a programmable controller, a backup redundant data is an important process, in this process, some important data, there is a current redundant equipment unsafe, thus binding the block chain of thought, the programmable controller of the redundant data is encrypted, it can not be altered to improve the safety PLC redundancy control. Swiss-controlled programmable controller Paul redundant control data backup method based on block chain technique, the invention can effectively strengthen the safety PLC backup data, to prevent the internal electrical equipment control building information leakage. By the perfect combination of technology and redundancy block chain technology, will further enhance the security level of the wisdom of building to a new level, to ensure the building electrical and mechanical equipment monitoring system can have high security and reliability.
Paul-controlled Suzhou Electronic Technology Co. relying on the Suzhou Industrial Technology Research Institute, East China University of Technology (Suzhou Industrial Technology Research Institute, East China University of Technology is to build the East China University of Suzhou National Hi-Tech Industrial Development Zone, is the establishment of the East China University of Technology the local independent business legal entities), production and research achievements at East China University of Science and Technology achievements based (co-Hua Institute of Technology School of information Science and Engineering, the number of doctorate), bringing together both the scientific and technological innovation resources, completely independent innovation model of development . High-tech Venture Capital Group, while the Soviet Union as a major shareholder, in terms of funding and policy to give strong support and support. Company R & D team brings together from Zhejiang University, Shanghai Jiaotong University, East China University of Technology and many other talents, it has these outstanding innovation ability and good cooperation between team members, providing a continuous and strong guarantee for the company's innovation and development.
