1、停机期间,首先搭建整个系统的网络平台,对现有主机柜进行改装,新增一对24口光纤交换机及其配套电源,并重新设置系统commit安装盘,定义整个网络结构。升级后的网络结构将非常简单并且稳定。13对控制器及8台工作站(操作员站6台,工程师站和历史站各1台)均通过冗余光纤直接接到交换机,形成冗余的Mesh网络结构。由现有#1机/炉控制器(型号为CP60)升级成新的控制器(型号为FCP270),升级后的控制器随卡件柜布置;
2、将公用系统和1#炉的控制器(型号为CP60)升级为新控制器(型号为FCP270),控制器不再集中布置,升级后的控制器随卡件柜布置。
3、对现有公用系统和#1炉及1#机卡件柜利旧改造,卡件底板更换为的FBM底板,原有卡件保留。
4、将工作站全部升级为的工作站(型号为H92),操作员站和工程师站性能将大大提升。
5、公用系统和1#炉及1#机升级完毕后,可根据要求启动公用系统和1#炉及1#机,进行正常生产运行,同时对2#炉、3#炉和2#机进行升级改造,这两个炉在升级后逐一接入新的Mesh网络系统,既保证生产安全,又使得现场停机时间不会太长,保证生产连续。

For example, Siemens S 7-214 above series, Mitsubishi’s A1S series, Matsushita’s higher-level PLC series and so on. According to the specific situation, in a distribution network automation, the whole distribution network system can choose the PLC of the same factory, also can choose the PLC of different factory according to the specific situation of the distribution room, in order to take advantage of the PLC of each factory and characteristics. The realization of RTU function by PLC includes two aspects: hardware realization and software realization. 3.1 in the aspect of hardware, there are some problems such as how to supply power of PLC, how to realize long-distance communication, and how to realize remote control, remote information, remote measurement and remote adjustment. Because of the special power supply module of PLC, when designing RTU, the power supply of PLC should be considered after the power cut off, which is usually solved by charging battery. The communication module of PLC only has the ability of short distance communication. Although some companies provide the network module for PLC, the communication distance is limited to a few kilometers. The distribution network is characterized by many points, wide area, so we must use other means to extend the PLC communication distance. There are many methods, such as telephone modem, special line Modem, wireless Modem, station-seeking Service, & Lt; PLC train number, cycle, batch, stock preparation 1. At present, the application of PLC technology in blast furnace automation control system is very common, especially in blast furnace feeding automation control. As an important part of the feeding automation control system, the feeding program plays a very important role in transforming the intention of the BF operator into an executable command of Plc The equipment under the blast furnace is usually composed of several raw material tanks and corresponding feeding equipment, weighing funnel, conveying belt, powder conveying belt and intermediate weighing hopper. Fig. 1 is a sketch of the more common arrangement of the equipment under the tank (shown in Fig. 1 is only on the lower side of the tank and similar on the other side) . The material preparation includes the material preparation of the weighing funnel (hereinafter referred to as the weighing hopper) and the intermediate weighing hopper (hereinafter referred to as the intermediate hopper) corresponding to the raw material trough. The former is relatively simple, when the weighing bucket electronic empty signal and the gate closed in place can start the corresponding feeder to prepare materials. Intermediate Hopper material preparation is in accordance with the batch operation system will be the weighing hopper of the material into which. It is a matter of choice as to when and which hoppers should be loaded. This article mainly introduces the procedure of this part. 4 program flow according to the blast furnace operation system, generally there are several batch, take Xinxing Ductile Iron Pipes Co LTD No. 2 blast furnace as an example (figure 2) .
