The development of modern industrial instrumentation , not only depends on the level of product technology, but also involves engineering application technology. In recent years, many measurement and control equipment manufacturing enterprises and thermal power, petrochemical, metallurgical and other application sectors of science and technology enterprises and engineering companies in the application software development and system integration technology has made considerable progress, through the foreign control system and product engineering applications , Mastered a number of large projects and installations of self-control application technology. However, with the development of foreign technology such as field bus, SOLUTION, MIV, EPC, etc., the difficulties of our automatic control system and field instruments entering large-scale projects will further increase. China's automation and control systems and field instruments and key precision test equipment, with the overall international level is still 10 to 15 years gap. China's instrument and meter technology breakthroughs need to step by step. Breakthrough one: to improve the digital, intelligent, integrated level Modern industrial instrumentation technical characteristics and trends are digital, intelligent, networked and integrated, and our products are generally more conventional varieties, smart products have just started. Taking nuclear power control system and instrument integration as an example, the gap is even bigger after entering the era of digital control technology due to the weak foundation. Breakthrough two: improve product reliability The overall characteristics of modern industrial instrumentation is high reliability, high performance, high applicability, most of our business products and foreign products is also the gap in this area. For example, China's own distributed control system developed DCS and electromagnetic flowmeter, the basic performance and function of these products is close to the international level, but there is a certain gap in terms of reliability and engineering capabilities. Breakthrough three: improve high-tech Foreign intelligent actuators have been using frequency control, new motors, low power consumption, miniature piezoelectric ceramic I / P converter, Bluetooth communications technology, intelligent and fieldbus and other new technologies, and domestic began to start. Breakthrough four: product precision more sophisticated To mass flowmeter, for example, foreign measurement accuracy is divided into four grades, the highest accuracy and can measure the gas to 0.1, the most common is 0.15, and currently can only reach the domestic economy class 0.2 and applicable 0.5 level. Another example is the measurement of gas stations in our country is generally. . 5% accuracy, but the accuracy of delivery of 300,000 tons of overseas oil tankers to China should be 0.1%. Break five: rich variety specifications Take high-precision intelligent pressure / differential pressure transmitter as an example, domestic transmitters lack the following low pressure of 1kPa, high pressure differential range of more than 800kPa, high static pressure of 16MPa, corrosion resistance and other specifications on the basis of the measurement range Some engineering or system application of the special requirements can not be met. Breakthrough six: improve the degree of automation For example, high-performance optical direct reading spectrometer, foreign instrument vacuum real-time monitoring by the computer, while the domestic equipment in many ways still need manual operation. Break seven: expand the share of high-end products At present, China's high-end products less, or even blank. Take atomic absorption spectrophotometer as an example, foreign countries have Zeeman background correction technology, high-end equipment, the domestic has not yet developed, high-end needs mainly rely on imports. Breakthrough eight: increase market share Programmable controller PLC, for example, the current Chinese PLC market more than 95% occupied by foreign products. European and American products in the field of large and medium-sized PLC occupies an absolute advantage, Japanese products occupy an advantage in the field of small PLC, South Korea and Taiwan products also have a certain market share. China's own brand PLC market impact is very small, it is difficult to form a economies of scale. The instrumentation market is also described above.
