近年来随着计算机技术的发展,计算机技术在水泥工业生产过程中被广泛使用,目前兴建或改造的大中型水泥生产线很多采用了DCS系统,但还有很多中小规模的水泥企业仍处于自动化水平相对滞后的阶段,仍使用传统仪表甚至靠人工进行监控。这对提高产品质量和产量,节能降耗,加强企业竞争力来说都是不利因素,而大型的DCS系统的成本相对较高,一般企业技改也无法接受。针对这些问题,我们开发设计了一套低成本DCS系统,并在石井水泥公司实施。由于公司的现场环境恶劣,除高温、多尘外,还大量使用变频器,使得电磁干扰比较严重,而且在水泥生产过程中,工艺检测点很分散,布线成本和工作强度均很大,因此,本着高性能价格比的原则,经过 In recent years, with the development of computer technology, computer technology has been widely used in the cement industry production process. At present, many large and medium-sized cement production lines constructed or reformed have adopted the DCS system. However, many small and medium-sized cement enterprises are still at the level of automation The lag phase is still monitored using traditional gauges or even manually. This is to improve product quality and output, energy saving, enhance the competitiveness of enterprises are unfavorable factors, while the cost of large-scale DCS system is relatively high, the general corporate technology reform also unacceptable. In response to these problems, we developed and designed a low-cost DCS system and implemented it at Ishii Cement. Due to the harsh site environment of the company, in addition to high temperature, dusty, but also the extensive use of frequency converter, making the electromagnetic interference more serious, but also in the cement production process, process detection points are scattered, wiring costs and work intensity are large, In the principle of high cost performance, after
