The hottest research and development of intelligen

Editor's note: domestic instrument manufacturers should strengthen technological investment and innovation, develop production line technology on the basis of introducing, digesting and absorbing foreign technology, improve the production quality of raw materials, and develop and produce more integrated chips with independent intellectual property rights. These are the top priorities of electrical instrument enterprises

"although instrument manufacturers are starting to develop intelligent electrical instruments, domestic enterprises must achieve breakthroughs in production line technology, measurement chip technology, material quality, etc. in this way, domestic products can compete with foreign products that violate the price of foam granulator, and can be competitive in the market." Ren dianyi, Secretary General of the electrical instrumentation branch of the China instrumentation Association, said in an interview

previously, some domestic instrument and meter manufacturers successively launched electrical test systems with self diagnosis function, and began to enter the field of intelligent instrument and meter market

however, Ren dianyi is still worried about the current production situation of domestic electrical instruments and meters. He said that as a major producer of electrical instruments and meters, although China's exports of instruments and meters have increased year by year, the export areas have been expanding. However, on the whole, there is still a certain distance from the advanced level of foreign countries, which is mainly manifested in: insufficient scientific research investment and low independent innovation ability; The manufacturing technology, material quality, chip core technology, production intensification and concentration, installation size standards and other aspects need to be improved

according to insiders, at present, most of China's electrical instrument and meter manufacturing enterprises only pay attention to product research and development and ignore the development of production line technology. Some enterprises' investment is also more inclined to product technology rather than production line technology, resulting in insufficient investment in hardware equipment. In this way, the automatic production level of the enterprise is not high, which makes it difficult to ensure the consistency of products

according to luhanxi, chief engineer of Linyang Electronics Group, the quality of raw materials used in the production of electrical instruments and meters in China also lags significantly behind that of advanced countries. For example, magnetic thrust bearing and damping magnet of induction watt hour meter. The following preparations should be made: the quality of the original device itself determines the service life of electrical instruments and meters, and its insulation performance, heat resistance and flame retardancy of the shell are the key factors to ensure the quality of instruments and meters

Lu Hanxi said, "in addition, China's ability to independently develop measurement chips, the core technology of electrical instruments, is insufficient, and there is a lack of innovation with independent intellectual property rights, which is also an important factor for the use of color pictures that hinders the development of China's instrument industry."

on how to improve the market share and competitiveness of domestic intelligent electrical instruments and meters, Ren dianyi suggested that domestic instrument and meter manufacturers should strengthen technological investment and innovation, develop production line technology, improve the production quality of raw materials, and develop and produce more integrated chips with independent intellectual property rights on the basis of introducing, digesting and absorbing foreign technology, This is the top priority of electrical instrument enterprises
