At present, the electrical control system of domestic dyeing and finishing pre-processing equipment, although a large number of PLC, inverter, touch display and other digital control devices and human-machine interface interface, but its function is limited to the synchronization control of multi-unit transmission. Many systems also commonly use analog synchronous controllers as auxiliary control units for PLCs. The same type of foreign equipment has been fully used in the FCS system for dyeing, soaping, cooking and bleaching, and other joint production lines. The electrical control system not only includes synchronization control, tension automatic control, automatic control of temperature, flow, and chemicals, workshop production process. Management, and the field bus elements constitute an organic whole.
The development of FCS technology has provided us with a practical, reliable and comprehensive technical platform for us to change the backward appearance of automatic control of domestic equipment. Although the core of FCS is the use of fieldbus technology, FCS is more important than the concept of a brand-new control system. It combines the achievements of computers, communications, distributed, information technology, smart meters, and transmission control to become the present day. The development trend of industrial control systems.
In recent years, Wuxi Bangzheng Automation Technology Co., Ltd. has used fieldbus technology to form different systems for devices such as color soaping machines, decoction and bleaching machines, mercerizing machines, and hot air primer machines, which proves that the system is reliable and technologically advanced. Regardless of the design concept, the advanced nature of the technology and the electrical performance indicators after the operation, it is not inferior to the imported equipment.
The new dyeing and finishing equipment FCS system is divided into two layers: the first layer is the TCP/IP Ethernet structure, and the industrial controller communicates with the PLC, adopts the ICP/IP protocol, the setting of process parameters, the monitoring of the production process, and the formulation management. All are completed by industrial controllers. Since the PLC and the inverter are connected through the Layer 2 FIPIO protocol, the parameter setting of the inverter and the display of the inverter working status can also be completed on the host computer.
FIPIO communication is Schneider's own communication protocol, the communication speed is 1Mpis, the longest communication distance is up to 15KM, the connection is convenient, and up to 64 contacts can be connected. PLC selected Schneider Premium series, which has the characteristics of fast operation speed, large memory capacity, powerful functions, and good expandability. The frequency converter adopts Schneider Company's ATV58 series, which can be applied to printing and dyeing plants and other harsh environments. Because the products of the same company are used, the communication protocol is the same. After the configuration is completed, the internal address in the inverter can be regarded as the internal address of the PLC. Therefore, the working status of the inverter can be clearly seen through the PLC.
In the dyeing and finishing production line, the number of transmission units is relatively large, and more than 40 units of the decoction and bleaching combined machine are available. The soaping machine also has more than 20 transmission units. The application of synchronous control technology is very beneficial to improving the overall performance. In this system, due to the use of fieldbus technology, the communication speed is very high, which provides a platform for real digital control. In practical use, the output of the angle sensor is connected to the inverter. The status of each angle sensor can be read through the communication between the inverter and the PLC. The PLC sets the speed signal and the angle signal of the angle sensor to operate. The actual operating frequency of each inverter is transmitted to the inverter through communication. Since the communication speed and PLC operation speed are very fast, the whole process can be completed in an instant, so the synchronization effect is relatively good, and the actual use effect is also satisfactory.
In this system, there are more than a dozen washing boxes, the temperature of a reducing steamer needs to be controlled, the temperature control is also completed by the PLC, and the degree of integration is high. In order to ensure the humidity, temperature and non-condensation required for the reaction process of the fabric in the reducing steamer, the control of the reducing steamer in the control system is specially treated so that the temperature, humidity and flow rate of steam entering the steamer All controlled.
As resource prices are getting higher and higher, and pollutant discharge requirements are becoming increasingly stringent, it is very necessary to automatically control the flow of water and chemicals. Therefore, the system can automatically control water flow and chemicals. The water flow is related to the width of the door, the weight of the fabric, the quality of the fabric, and the speed of the vehicle. The system can automatically perform calculations and control the flow of water. Chemical controls include pH control, oxidant control, and more.
In this system, Ethernet communication is used between the host computer and the PLC. All the parameters can be displayed on the computer in real time. In order to reduce the workload of craftsmen, 100 recipes have been prepared in the upper machine, and different varieties have been exchanged. The craftsmen can quickly realize the use of different craft numbers. At the same time, the Ethernet interface with the shop floor management network is reserved in this system. Only by directly accessing the network, the already established data files in the system can be delivered to the management level or directly subjected to production order information.
