Abstract: In recent years, with the progress of science and technology in my country, intelligent manufacturing, "Internet +", big data, cloud computing, Internet of Things, artificial intelligence have become the main directions of all walks of life, and these technologies are gradually infiltrating the design of electronic scales, production, manufacture and application. Electronic weighing apparatus is a technology integrating machinery manufacturing, materials, information and management. Combined with the development of electronic weighing instruments at home and abroad, we have developed the research focus from single weighing to intelligent automation, miniaturization, integrated weighing and weighing systems dedicated to various industries, making electronic weighing no longer simple. It is a multi-functional weighing system or a weighing system dedicated to some specific scenarios.

Key words: electronic weighing instrument; intelligence; Internet of things; development trend;

This paper analyzes the development status of electronic weighing instruments in my country, and then finds out through investigation that there may be a series of problems caused by substandard raw materials in the application of electronic weighing instruments in my country at this stage, incomplete consideration in the manufacturing stage of electronic weighing instruments or the production environment does not meet the requirements. problems and proposed solutions. Finally, a prospect is put forward for the digital and intelligent transformation and upgrading of electronic weighing instruments under the background of 5G technology, artificial intelligence and independent chip development in the future electronic weighing instrument manufacturing industry.
1. Development Status of Electronic Weighing Apparatus

Compared with developed countries such as Europe and the United States, my country's electronic weighing instrument manufacturing industry started late, and it took shape in the mid-1950s. In the 1960s, electromechanical integrated electronic weighing instruments were gradually put into production and use, but the operation of this model was complicated and the weighing results were easily disturbed by environmental factors, which cost a lot of manpower and material resources. In the past half century, with the substantial improvement of my country's national strength, electronic weighing technology and computer intelligence technology have become more and more mature, and electronic weighing technology has also developed rapidly. conversion. The detection and measurement method has been upgraded from analog measurement to more accurate digital measurement, and the weighing method has also developed from the original static weighing mode to today's dynamic and static combined weighing mode, with more convenient operation, richer functions and wider application range . Through the research, analysis and classification of the development of electronic weighing apparatus products and the needs of domestic and foreign markets, at present, the overall development trend of electronic weighing instruments in my country can be summarized as: ① miniaturization, ② modularization, ③ integration, ④ intelligence . The development trend of technical performance can be summarized as: high efficiency, high precision, high stability and high reliability. Application performance can be summarized as: comprehensive, combined, comprehensive.
Second, the use of electronic weighing features

Before the advent of electronic weighing instruments, people used traditional wooden weighing instruments for measurement work, and their standard scales were manually measured, so there would be large errors in measurement accuracy, and even artificial fraud would occur. Since the 20th century, with the emergence and development of sensing technology, electronic weighing instruments have gradually appeared in the public's field of vision, and soon electronic weighing instruments have gradually replaced traditional artificial wooden weighing instruments with their advantages of high precision, high sensitivity and easy reading. Various countries have also promulgated corresponding standards and specifications, which clearly put forward the requirements that electronic weighing instruments should be used in measurement occasions. Electronic weighing instruments have also undergone many upgrades, and finally developed into more mature electronic weighing instruments that meet the specific requirements of various industries. At present, electronic weighing instruments with a measurement range of 1-1000kg are the most widely used, and can be larger or smaller according to the requirements of the industry. Contemporary electronic weighing instruments can not only meet the daily high-load workload, but also the cumulative error generated has little impact on normal work, and also eliminates the daily complicated maintenance work of weighing instruments, which is also an important factor for electronic weighing instruments to develop into mainstream weighing instruments. one of the reasons.
In short, the electronic weighing industry is a traditional processing and manufacturing industry. With the development of 5G network, Internet of Things, artificial intelligence, chip technology and electronic weighing technology, it will provide new opportunities for the electronic weighing industry, making it a high-added value industry. The electronic weighing instrument in the future may no longer be just a single scale, but a smart one that integrates multiple functions (such as: unattended, intelligent computing, monitoring, identification, information processing, etc.) and can be connected to intelligent hardware. weighing system.
