Description
Technical Field
The invention relates to the technical field of tunnel boring machines; in particular to a tunnel tunneling information acquisition platform capable of acquiring all-around information.
Background
With the development of computer technology, communication technology and control technology, the traditional control field is undergoing an unprecedented revolution and starts to develop towards networking. The structure of the control system has been developed from the first CCS (computer centralized control system), to the second generation DCS (distributed control system), to the now popular FCS (field bus control system). The field bus is a digital, bidirectional transmission and multi-branch structure communication network for connecting intelligent field devices and an automation system, and is a serial, digital and multi-point communication data bus installed between the field devices/instruments in a production process area and an automatic control device/system in a control room. A Fieldbus Control System (FCS), which is essentially a computer local area network system, interconnects individual controllers and meters and meter devices on the field using an open, interoperable network, which is a fieldbus, while control functions are completely released to the field, reducing installation and maintenance costs. The system is a new generation control system behind a relay type pneumatic instrument control system, an electric unit combined type analog instrument control system, a centralized digital control system and a Distributed Control System (DCS). Currently, there are over 40 types of field buses known internationally, and the more typical field buses are: FF, PROFIBUS, LonWorks, CAN, HART, CC-LINK, etc. Among them, the data transmission rate of the PRFIBUS is fast, the SIEMENS automation equipment level communication solution, namely the PROFIBUS bus, has been widely adopted, managers and technicians of an enterprise have certain knowledge on debugging and maintenance of the bus, and most support the PROFIBUS communication in the field of electric transmission, regardless of a branch or an alternating-current transmission device.
Industrial ethernet is a local area network technology that applies ethernet to industrial control and management. Conventional control systems typically employ ethernet at the information level, and different field buses or other proprietary networks at the control and device levels. But ethernet has now penetrated both the control and device layers and has begun to become a member of the field control network. The fieldbus standard is characterized by simpler communication protocol and lower communication rate. With the improvement of the intelligence of the instruments, the transmitted data is more and more complex, and even data files and Web pages are transmitted, so that the high speed and the diversity of forms of network transmission become more important in a control system. However, ethernet and TCP/IP are not originally control-oriented, and have a large difference from mature automation solutions (such as PLC, DCS, FCS) in terms of architecture, protocol rules, physical media, data, software, applicable environment, and so on. In addition, in the traditional ethernet, a bus topology structure and a CSMA/CD are adopted, and under the situation that the real-time requirement is high, transmission delay is generated in the transmission process of important data, which is called as uncertainty of the ethernet. This is one of the important reasons that affect the long-term inability of ethernet to directly enter the process control domain. The real-time problem of industrial Ethernet can be well solved, and the problem of application limitation of the traditional Ethernet in the tunneling process can be effectively solved. Aiming at the problems, how to effectively solve the problem of seamless integration between a basic automation control network and a process and management control system in the technical field of tunnel boring machines through the mutual fusion of an industrial Ethernet technology and a field bus control system is a technical problem which is urgently needed to be solved in the technical field of tunnel boring machines. At present, the complementary advantages and mutual fusion of the industrial ethernet technology and the fieldbus control system become a development direction in the field of automatic control, and therefore, based on the industrial ethernet technology and the fieldbus control system, a tunnel tunneling information integration platform capable of collecting all-around information is imperative.
