background brief introduction:

the tire manufacturing industry is developing rapidly in China's economic development, especially in the context of the rapid development of the automotive industry. The total assets and sales revenue of the industry show a rapid growth trend. From the perspective of future market development, it is predicted that China's tire demand will reach 160million to 170million in 2005, and the tire output will reach more than 250million in 2010. With the continuous expansion of the tire market and the improvement of consumers' requirements for tire quality, a high standard and efficient production system has become very important for tire manufacturers. Therefore, high-quality industrial control equipment is more and more widely used in the tire manufacturing industry. Even for manufacturers, whether to use high-quality industrial control equipment has become a matter of life and death

system process:

tire production includes: internal mixing, extrusion, calendering, bead forming, cord cutting, vulcanization and other complex processes

each process includes a very complex process

system principle:

in the process of tire production, after receiving the process parameters, the industrial control host of tire manufacturing transmits the signals to the programmable controllers (PLC) of internal mixer, extruder, calender, bead former, cord fabric cutter, vulcanizer and other machines, and then each programmable controller transmits the signals through its output port, so that the machine can perform the whole internal mixing, extrusion, calendering, bead forming Cord cutting, vulcanization and other processes to complete the work. In each stage of the internal mixing cycle, the speed of the main motor is set by the process parameters. In the process of internal mixing meeting a series of relevant experimental standards, the programmable controller records some process data and whether the equipment is in good condition, and transmits the internal mixing data to the industrial computer as the basis for the industrial computer to control the internal mixing action and the end of the internal mixing cycle. At the same time, the system will automatically adjust the speed of the extruder according to the internal mixing conditions and automatically adjust the pressure between the pressure roller and the extruder head to the set value. With the increase of the rubber in the hopper, the speed of the extruder will also accelerate, the head pressure will increase, and the calender will also automatically increase the speed to keep the pressure at the set value until the extruder speed increases to the maximum and the calender speed is the maximum. When the material level of the extruder hopper rises to the upper limit

, the extrusion opportunity requires the internal mixer to stop temporarily. After the material level drops to the middle level, the internal mixer will continue to work. In the preparation process of rubber parts, the calender presses the framework material required by the tire into the rubber, and presses the rubber into a certain shape according to the preset parameters of the industrial control host. In the process of tire forming, the machine automatically completes the processes of length fixing, cutting, synchronous fitting and shaping according to the set parameters, so that the tire is basically formed. In order to strengthen the wear resistance and rolling resistance of the tire, vulcanization is needed to enhance the strength of the tire. The change of pressure and temperature during tire vulcanization directly affects the quality of tire vulcanization, which requires that the industrial control system strictly monitors and controls the vulcanization temperature and pressure to make it proceed according to the preset value during tire vulcanization, and when the temperature and pressure are insufficient, the automatic delay vulcanization method is adopted to compensate the temperature and pressure

each tire contains more than 150 components. In the tire production process, the process from raw material preliminary processing to calendering forming to the final end is complex and long, which requires high efficiency, stability Precise server level terminal to do specific configuration control. Not only does the company need to have good expansion capability, multi-channel communication capability (at least 4-channel communication ports), a certain hot standby mechanism, but also excellent control capability (able to control multiple machines to run at the same time, coordinate with each other, and keep pace) 。 The 4U industrial computer of Aixun technology has reasonably solved the control problems in tire production. The machine has 6*isa/7*pci/1*picmg and has good expansion capability. Syba's PCI port card extends two RS232. In addition, Aixun sbc81822vecd comes with two RS232. A total of four RS232 are convenient for customers to connect various peripheral devices. SOHO raid sr-2500 and syba channeling card are added. The sr-2500 adopts the disk mirror principle, which enables two hard disks to record data at the same time. No matter which hard disk is damaged, the other one is automatically enabled, and there is no need to issue any instructions. At the same time, scholars gradually realized that there may be an undiscovered failure mechanism when using polyether polyurethane (PEU), so it is necessary to further study the IDE hard disk hot plug function to facilitate backup and maintenance, It is a very effective hot standby mechanism. Sbc81822vecd P4 motherboard, P4 2.8GhZ CPU and Kingston 512M DDR are used, which has very strong computing and control capabilities
