在系统中,对于高炉本体仪表和炉定设备采用传统的布式I/O结构,对于热风炉、煤气净化(布袋)系统、框槽配料系统采用仿现场总线方式。在这样方式下把以上三个系统根据系统中的单体进行现场小型PLC控制和电气控制,由现场的PLC完成单体功能控制和电气操作,而由上一级PLC实现生产过程工艺协作控制。现场PLC子系统和上一级PLC通过通讯进行连接。 从实际意义上说,该系统不是完全的现场总线方式,而是借鉴了现场总线的现场智能控制的理念,因此称为仿现场总线控制。
In the system, the traditional cloth I / O structure is adopted for the blast furnace body instrument and furnace setting equipment, and the imitation fieldbus mode is adopted for the hot blast stove, gas purification (bag) system and frame slot batching system. In this way, the above three systems carry out on-site Small PLC control and electrical control according to the monomer in the system, the on-site PLC completes the monomer function control and electrical operation, and the upper PLC realizes the process cooperation control of the production process. The on-site PLC subsystem is connected with the upper PLC through communication. In a practical sense, the system is not a complete fieldbus mode, but draws lessons from the concept of field intelligent control of fieldbus, so it is called imitation field general control system
