Cement production in the PLC frequency interference and anti-interference

Feature strong advantages. The anti-interference measures are mainly limited filtering amplitude filtering, median filtering, arithmetic mean filter,[link widoczny dla zalogowanych], median average filtering method (also known as the anti-pulse interference averaging filter), and (limiting) debounce filtering method. Vulnerable to interference of certain control signals, in the PLC program to make the appropriate delay treatment. The software is an effective way of filtering applications. In addition, there are several possible methods. If the signal relay terminal plus: Choose an increase slightly larger than the interference voltage relay voltage level to protect the I / 0 点: PLC Emerson from the AC current power supply to bring the latest technology products including energy integration in the overall network solutions at 1 () 18 at the \, more recently won the \of modular design, is more important is the program all the devices are Emerson Our products, whether stability or compatibility have reached the highest index that can provide high-quality clean power, communication services do not meet the continuous, trouble-free operation needs. Also avoid failure due to the interaction between multiple suppliers to delay recovery buck the case, the normal operation of the main device to provide more high-quality service and more reliable power protection. Emerson successfully for the state Internet Network Information Center (China Computer Network Management Centre) to provide power distribution, UPS, precision air conditioning, STS, power and environment integration, design, implementation and services, improve the reliability of the system and shorten the construction period of up to 50% 99.99999% reliability of the system. Success provided the impetus for a number of areas mentioned solutions. DC power supply (some PLC the input and output modules for the AC and DC); signal model from DC voltage signal into 4 ~ 20mA current signal. 5 Conclusion With the automation equipment in cement production are gaining in status, their interference and anti-interference measures are more and more corporate attention. Actual production, the drive for electric and electronic signals of the same carrier. Well received by the on-site power and electrical equipment interference, will interfere with other devices in the run-time operation. Therefore,[link widoczny dla zalogowanych], the frequency of anti-interference measures, not only protect themselves,[link widoczny dla zalogowanych], but also to reduce interference from other devices on the PLC. Similarly, PLC control system interference is a very complex issue, in the design and application should be taken into account various factors, reasonably and effectively suppress interference and PLC control system to work,[link widoczny dla zalogowanych], so that cement production can be continuous and stable manner.
