1. As an important component of measuring instruments, weighing instruments are mainly used to measure the mass of objects or other numerical values, quantities, parameters or characteristics that serve as a function of mass. As a legally mandated measuring instrument by the state, weighing instruments are an important means of weighing control and trade measurement, widely used in various industries. However, at the same time, they also put forward increasingly high requirements for the development of weighing technology.

In recent years, China has made significant progress in the technology and production of weighing sensors and display controllers, and the production and quality of domestically produced electronic scales have also been continuously improving. Chinese scales are bidding farewell to the era where mechanical scales dominate. The ten categories of scales classified in China's standards (platform scale, table scale, ground scale, ground scale, suspended scale, belt scale, hopper scale, inspection scale, track scale, and special scale) have all achieved electronic product digitization in China. A relatively mature static weighing scale can range from 1 μ From g to 800t, non automatic scales have reached the international technical level in the early 1990s, such as electronic price scales, electronic platform scales, electronic ground scales, electronic belt scales, electronic suspension scales, and electronic track scales. Since the reform and opening up, foreign-funded enterprises have successively brought a batch of advanced scale products and technologies from abroad, such as strain gauges, sensors, instrument production technology, quantitative packaging scales, automatic weight inspection scales, label pricing scales, computer combination scales, pressure resistant measuring coal feeders, etc. This is not only a supplement but also a promotion for China's scale industry. The Chinese weighing instrument industry with an ancient history is highly integrating modern advanced science and technology, becoming an emerging high-tech equipment industry.
2. The Development Trend of Scale Technology in China
(1) Intelligent digitization
The intelligent digital weighing system is mainly composed of intelligent instruments, digital sensors, and digital junction boxes, including digital instruments, digital transmitters, sensors, and intelligent self-control software. It is a new concept of weighing technology in the 21st century. Its advantages mainly lie in the ability to detect and process weighing signals, make free logical judgments, self detect and self diagnose, and perform self correction and compensation when deviations occur. Furthermore, from a structural perspective, it can be either a holistic integrated structure or a separate modular structure. At present, digital intelligent weighing sensors have been applied in various intelligent closed-loop controls.
(2) Networking of weighing system information
With the integration of the global economy, information technology has developed rapidly. Computer software, industrial control and other technologies have been widely used in the weighing control bus technology, mainly manifested in the application of information technology in intelligent weighing systems. It consists of four parts: weighing equipment, intelligent networked control system, embedded weighing software, and comprehensive weighing management software. The networking of weighing system information can not only improve work efficiency, but also maintain the interests of weighing enterprises.
(3) Scale structure miniaturization and modularization
Compared with traditional electronic scales, modern electronic scales are smaller in size, lower in height, and heavier in weightLightweight is currently the trend of development. Small weighing electronic scales can use thin or ultra-thin weighing elements, which will appear low in appearance. On the other hand, larger or ultra large load-bearing structures, such as large static and dynamic electronic car scales, have begun to use length standard modules for the scale body. By combining them separately, new varieties and specifications are produced.
(4) Multifunctionality and Integration
The embodiment of electronic scales in industry not only requires scales to have very accurate weighing functions, but also monitoring functions, alarm functions, printing and statistics functions, and network information statistics management functions. However, traditional electronic scales only have simple functions such as weighing, pricing, display, and printing. For modern commercial systems, the functions of traditional electronic scales are far from sufficient. Modern business systems require it to provide various sales information, combine weighing with management automation, and provide one-stop services for weighing, pricing, and sales, truly achieving management automation. This requires electronic scales to be connected to electronic computers to achieve a complete integrated control system.
3. Analysis of Highway Intelligent Weighing Informatization Products
Since the Ministry of Transport issued the "Guiding Opinions on the Trial Implementation of Weighted Toll Collection on Toll Highways" in October 2005, the implementation of weight-based toll collection on highways has rapidly spread across the country. The number of provinces and cities implementing weight-based toll collection has increased from 7 in early 2006 to 30, and it is actively and steadily being promoted nationwide.
When implementing road weight charging, all provinces choose the dynamic axle weight weighing method to charge for passing toll vehicles. Through years of weight charging practice, it has been shown that this method has made great contributions to the promotion of weight charging in China in the early stages of weight charging. However, with the comprehensive implementation of weight charging, its shortcomings have become increasingly prominent, mainly manifested in drivers being able to cheat through various non-standard driving methods such as pounding, jumping, walking in an S-shape, using steel plates, and using jacks.
As a weighing device for weighing and toll collection, the vehicle type weighing and toll collection system has gradually become the mainstream equipment in the highway weighing equipment market due to its advantages of high accuracy, high reliability, and prevention of cheating in collecting weight data. Since the comprehensive implementation of the whole vehicle weight charging system in Shaanxi Province in 2010, more and more provinces across the country have been carrying out the work of "dynamic to static" weight charging.
At the same time, the country is widely carrying out the construction of intelligent weighing information technology for highways based on weight measurement, including vehicle type weight measurement and toll collection system, axle load dynamic weight measurement and toll collection system, truck ETC, highway entrance weight blocking system, high-speed pre inspection system, and off-site law enforcement system for limit detection. The Ministry of Transport attaches great importance to the informatization work of highways and proposes that the promotion of transportation informatization construction must be placed in a prominent position in transportation planning. Through the implementation of a number of major informationization projects with strong driving force, the level of transportation intelligence and modernization will be comprehensively improved. With the development of highway informatization, the highway intelligent weighing informationization product industry will usher in unprecedented rapid development.
4. Analysis of Industrial Intelligent IoT Weighing System Products
Industrial weighing is a measuring instrument used to determine the mass of an object.The earliest scales used by humans were primitive scales. Modern industrial weighing mainly consists of three parts: load-bearing system (such as weighing platform), force conversion system (such as sensor), and indication system (such as display). Industrial weighing is widely used in various fields such as industry, agriculture, commerce, foreign trade, transportation, healthcare, national defense construction, and scientific research. With the development of computer, automation control, microelectronics and other technologies, industrial weighing products have transitioned from being dominated by mechanical scales to knowledge intensive all electronic weighing high-tech that integrates multiple electromechanical technologies such as computer, microelectronics, information processing, and automatic control. At the same time, industrial weighing technology has evolved from static to dynamic and automatic online, from analog to digital, and from single parameter to multi parameter synchronous measurement. The research and application of fast, online, and dynamic weighing are particularly urgent. At present, industrial weighing has become the core of IoT technology and forms an industrial intelligent IoT weighing system with mobile internet and cloud computing technology.
Due to the increasing emphasis on controlling the quality of materials, coal energy, and other mineral materials by enterprises in various industries, industrial weighing products have entered a stage of rapid development. The product design, manufacturing, and installation capabilities of production enterprises in the industry are constantly improving with the growth of downstream demand. The speed of technological innovation in the measurement accuracy, equipment operation stability, and automation level of industrial weighing equipment is unprecedented. The technical level of some products has synchronized with the world's advanced level.
5. Industry upstream and downstream relationships
The upstream of the weighing equipment industry mainly includes the steel industry, electronic components and sensors, industrial control computers, printers, high-speed rail machines, vehicle separators, RF cards, IC cards, etc. In recent years, there have been significant fluctuations in the prices of major raw materials such as steel, especially the price changes of specialized steel plates that have certain requirements for working conditions such as operating temperature and working environment, which have greatly affected the overall production cost of the industry. Overall, the changing trend in prices of various specialized steel plates will affect the average profit margin of the weighing instrument industry.
The downstream of the weighing instrument industry is mainly in industries such as coal, chemical, electric power, metallurgy, industry, transportation, and national defense. Therefore, there is a strong correlation between the development and prosperity of these downstream industries and the development of the weighing instrument industry. With the acceleration of industrial structure adjustment and the transformation of economic development mode in China, some traditional industries with overcapacity will continue to face the process of phasing out outdated production capacity, and the growth rate may slow down. However, emerging fields such as intelligent transportation, advanced manufacturing, and the Internet of Things will benefit from the support of relevant national policies and have good development prospects.
