[0040] The blast furnace distributed control (DCS) device 130 can be used to collect process data of the blast furnace area and output second processed process data.
[0041] Exemplarily, the blast furnace distributed control (DCS) device 130 can be installed in the local blast furnace blower process room, collect vibration data sent by the 3500 vibration device through the 485 interface, and after processing, send the data to the local industrial computer through the RJ45 interface.

The switch can receive process data from the blower control device and the energy operation center SCADA device, respectively, and process these data, and then send the processed process data to the centralized monitoring industrial computer through the network.
[0047] The switch can provide a large number of ports for cable connection, which increases the types and quantity of data transmission equipment that can be connected to the blast furnace blast data transmission system, and improves the applicability of the blast furnace blast data transmission system.
[0048] See again Figure 2 The system may further include: a first data forwarding device, used to receive process data of the blower area from the switch, so as to forward the process data of the blower area to the data acquisition and monitoring device of the energy operation center, and also used to receive the first processed process data from the data acquisition and monitoring device of the energy operation center, so as to forward the first processed process data to the centralized monitoring industrial computer; and a second data forwarding device, used to receive process data of the blower area from the switch, so as to forward the process data of the blower area to the blast furnace distributed control device, and also used to receive process data of the blast furnace area from the blast furnace distributed control device, so as to forward the second processed process data to the centralized monitoring industrial computer.
[0049] Specifically, the first-phase dehumidification PLC device, as a supporting facility of the first-phase blast furnace blower station, is mainly used to collect process data of equipment such as refrigerators, filters, water pumps, valves and instruments in the dehumidification station supporting the first-phase blast furnace blower station, and transmit the data to the switch after processing. The second-phase dehumidification PLC device, as a supporting facility of the second-phase blast furnace blower station, is mainly used to collect process data of equipment such as refrigerators, filters, water pumps, valves and instruments in the dehumidification station supporting the second-phase blast furnace blower station, and transmit the data to the switch after processing. The first-phase blast furnace blower PLC device, as the main facility of the first-phase blast furnace blower station, is mainly used to collect process data of equipment such as blowers, oil stations, water pumps, valves and instruments in the first-phase blast furnace blower station, and transmit the data to the switch after processing. As the main facility of the second-phase blast furnace blower station, the PLC device of the second-phase blast furnace blower is mainly used to collect the process data of the blowers, oil stations, water pumps, valves, instruments and other equipment of the second-phase blast furnace blower station, and transmit the data to the switch after processing. As the supporting facility of the blast furnace blower station, the PLC device of the pump room is mainly used to collect the process data of the pumps, valves, instruments and other equipment of the supporting pump rooms of the first and second-phase blast furnace blower stations, and transmit the data to the switch after processing. As the main device for data interaction of blast furnace blowers, the switch is connected to other devices through the network time (NTP) protocol, and collects process data of the pump room PLC device, the first-phase dehumidification PLC device, the first-phase blower PLC device, the second-phase blower PLC device, and the second-phase dehumidification PLC device through a serial communication protocol, such as the MODBUS protocol, and forwards the collected process data to the first data forwarding device, the centralized monitoring industrial computer, and the second data forwarding device through the MODBUS protocol; the first data forwarding device is connected to the switch and the energy operation center data acquisition and monitoring (SCADA) device 120 through the NTP protocol. The process data sent by the switch is collected through the MODBUS protocol, and the data is forwarded to the energy operation center data acquisition and monitoring (SCADA) device 120, and data interaction is performed with the energy operation center data acquisition and monitoring (SCADA) device 120 through the MODBUS protocol, and the data is forwarded to the centralized monitoring industrial computer. Further, the second data forwarding device is connected to the switch and the blast furnace DCS device through the NTP protocol. The process data sent by the switch is collected through the MODBUS protocol, and the data is forwarded to the blast furnace DCS device. The blast furnace DCS device also interacts with the blast furnace DCS device through the MODBUS protocol and forwards the data to the centralized monitoring industrial computer. The blast furnace DCS device is connected to the second data forwarding device through the NTP protocol and interacts with the second data forwarding device through the MODBUS protocol. The energy operation center SCADA device is used to collect process data in the energy area, and is connected to the first data forwarding device through the NTP protocol, and interacts with the first data forwarding device through the MODBUS protocol.The centralized monitoring industrial computer collects process data of the pump room PLC device, the first-phase dehumidification PLC device, the first-phase blower PLC device, the second-phase blower PLC device, the second-phase dehumidification PLC device, the blast furnace DCS device and the energy operation center SCADA device transmitted by the switch, the first data forwarding device and the second data forwarding device through the MODBUS protocol, and automatically optimizes and adjusts the operating conditions of the blast furnace blower.
[0050] Therefore, the data transmission system can obtain the process data transmission status of the blast furnace blower, blast furnace system, and energy operation center in real time, realize the integration of the process data of the three parties, and provide a more effective means of adjusting the blast furnace blower. At the same time, it also has powerful data storage and processing capabilities, centralizing the online and offline data of interactive process data on a unified platform to meet the needs of users at all levels. In addition, the above data transmission system provides multiple data interfaces including RS-485, TCP / IP, OPC, MODBUS, etc., with good expansion performance.
[0051] Optionally, the system may also include: an energy timing system, which is respectively communicated with the blower control device, the energy operation center data acquisition and monitoring device, the blast furnace distributed control device, the switch, the centralized monitoring industrial computer, the first data forwarding device and the second data forwarding device; wherein the energy timing system is used to provide a unified reference clock signal for the blower control device, the energy operation center data acquisition and monitoring device, the blast furnace distributed control device, the switch, the centralized monitoring industrial computer, the first data forwarding device and the second data forwarding device.
[0052] It can be understood that if the clock of the data in the steel plant is not unified during the transmission process, the various systems in the whole plant cannot be analyzed and compared on the basis of a unified time reference, which brings great hidden dangers to effective energy operation management, correct analysis and statistics of energy costs and energy forecasting. Therefore, an energy timing system is introduced here to send a unified reference clock signal to the blower control device, the energy operation center data acquisition and monitoring device, the blast furnace distributed control device, the switch, the centralized monitoring industrial computer, the first data forwarding device and the second data forwarding device. Exemplarily, when the blast furnace blower is operating normally, the energy timing system can receive the time reference signal sent by the global satellite positioning system or the Beidou satellite, and then send a unified reference clock signal to the blower control device, the energy operation center data acquisition and monitoring device, the blast furnace distributed control device, the switch, the centralized monitoring industrial computer, the first data forwarding device and the second data forwarding device through the network, thereby completing the time unification of the control system and effectively improving the efficiency of energy operation management. In one embodiment, the reference clock signal can be a pulse-per-second timing signal (IRIG-B code). IRIG-B code, referred to as B code, is a precise time standard based on satellite signal transmission. It can synchronize the time of the device by receiving the B code signal and converting it into a time signal. The clock accuracy is extremely high.
[0053] Alternatively, the reference clock signal can also be a network time synchronization (NTP) signal. Network time synchronization is to synchronize the time between devices through the time synchronization protocol in the Internet protocol stack. It is necessary to run synchronization software in the device connected to the Internet and communicate with the NTP server on the network to obtain accurate time, and the clock accuracy is high. Specifically, it can be a simple network time synchronization (SNTP) signal.
[0054] Optionally, a centralized industrial control monitoring machine is installed in the main control room of the first phase blast furnace blower, which can optimize and adjust the operating conditions of the blast furnace blower station.
[0055] In a specific embodiment, under normal system operation, the PLC system of this station in the blast furnace blower area collects the process data of the equipment in this station, and after processing, the switch sends the process data to the first data forwarding device, the second data forwarding device and the centralized monitoring industrial computer; the first data forwarding device sends the process data in the energy area to the centralized monitoring industrial computer through data interaction with the SCADA device of the energy operation center, and sends the process data in the blower area to the SCADA device of the energy operation center; the second data forwarding device sends the process data in the blast furnace area to the centralized monitoring industrial computer through data interaction with the blast furnace DCS device, and sends the process data in the blower area to the blast furnace DCS device. Finally, the process data after interaction is processed and stored by the centralized monitoring industrial computer, and then presented to the blast furnace blower operator for browsing. The energy timing system provides accurate clock signals for each part. The data transmission, forwarding and interaction between the above-mentioned devices are all automatically completed by the system, without involving manual operation. In addition, the data transmission system also has a self-diagnosis function, which can report the equipment failure information of the blast furnace blower, the energy operation center, and the blast furnace system to the main control room at all levels in real time.
