1、 Current situation
The infiltration of electronic technology in the mid-1950s propelled the development of the weighing instrument manufacturing industry. In the early 1960s, electromechanical electronic devices emerged
Since the establishment of weighing instruments, after more than 40 years of continuous improvement and perfection, China's electronic weighing instruments have evolved from electromechanical combination to the present
Fully electronic and digitally intelligent. The technical equipment and testing methods of electronic weighing instruments in China have basically reached the 1990s
Mid term level. The manufacturing technology and application of electronic scales have made new developments. Electronic weighing technology shifts from static weighing to dynamic weighing
Development: The measurement method has evolved from analog measurement to digital measurement; The measurement characteristics have evolved from single parameter measurement to multi parameter measurement
Don't focus on the research and application of rapid weighing and dynamic weighing. But overall, the quantity and quality of electronic weighing products in China
There is still a significant gap compared to industrialized countries, mainly due to inadequate technology and processes, as well as inadequate process equipment and testing equipment
Aging of the table, insufficient development capability, limited variety and specifications of products, incomplete functionality, poor stability and reliability, etc. But in recent years
Invest key research and development funds in the country to continuously accelerate its development speed.
2、 Development Trends
By analyzing the development of electronic weighing products in recent years and the demand of domestic and foreign markets, the overall development trend of electronic weighing is
Miniaturization, modularization, integration, and intelligence; Its technical performance tends towards high speed, high accuracy, high stability, and reliability
High sex; Its functional trend is towards an "intelligent" function that emphasizes both control and non control information in weighing and measurement; Its application performance trend
Towards comprehensiveness and combination.
1. Miniaturization
Small in size, low in height, and lightweight, that is, small, thin, and light. The newly developed electronic platform scale structure in recent years fully reflects the small
The development direction of thinness and lightness. For low capacity electronic platform scales and electronic axle scales, thin or ultra-thin circular scales can be used
A weight sensor is directly embedded into a blind hole on the bottom surface of a steel or aluminum plate that has the same outer diameter as the weight sensor, forming a low profile scale structure
The number and position of weighing sensors are determined by the rated load and mechanical requirements of the scale. Steel or aluminum plate is the body of the scale
The tabletop and weighing sensor are both sensing elements and load-bearing points, greatly reducing the structure of the scale and minimizing the need for active connections
The process not only reduces costs, but also improves stability and reliability. For electronic platform scales and electronics with medium or large capacity
Sub ground scales have emerged using thin-walled steel with square or rectangular closed cross-sections, which are welded in parallel rows to form a whole
The bamboo raft structure of the scale body is equipped with four weighing sensors installed in the notches at both ends of the two thin-walled steel sections on the outside
The fixed support on the load-bearing point of the weighing sensor is the load-bearing fulcrum of the scale body, which not only reduces the load-bearing transmission mechanism but also saves time
The height of the scale body is a very promising structure for scale development. For large electronic platform scales, the finite element method can be used
Calculation of equivalent strength and stiffness, using profiles with high bending stiffness and
Lightweight corrugated sandwich steel plate, etc.
2. Modularization
For large or ultra large load-bearing structures, such as large static and dynamic electronic truck scales, several length standards have been adopted
The quasi structured modules are combined separately to produce new varieties and specifications. Using (5, 6
7) Taking three standard modules with the same width and length of m as an example, they can be combined into three parts: single block, two block, three block, and four block
22 types of split scale body structures with lengths ranging from 5 to 28 meters. Of course, in practical applications, according to the needs of users in various industries
Yes, select more than 10 commonly used standard specifications. This modular split scale structure not only improves
The universality, interchangeability, and reliability of the product greatly improve production efficiency and product quality. At the same time, it also reduced
Cost has enhanced the market competitiveness of enterprises.
3. Integration
For certain types and structures of electronic scales, such as small electronic platform scales, scales, portable static and dynamic electronic axles
Scales, static and dynamic electronic track scales, etc. can all realize the connection between the scale body and the weighing sensor, the connection between the steel rail and the weighing sensor, and the scale body of the track scale
Integration with railway lines. A portable static and dynamic electronic axle scale that integrates the scale body and weighing sensor, often made of hard aluminum alloy
Made of thick plates. The structural principle is to strengthen the aluminum alloy plate through solid solution heat treatment, or to separate it by drilling and milling grooves at the four corners
Do not form four cantilever beam type weighing sensors; Or milling multiple symmetrical blind holes and blind grooves on the bottom surface of the aluminum alloy plate to form a whole
Shear beam type weighing sensor. This combines the scale body and the weighing sensor into one, where the aluminum alloy plate serves as both the scale body platform and the weighing sensor
A large plate type weighing sensor. Taking the 10t portable dynamic electronic axle scale with the latter structure as an example, its dimensions are
720mm × 550mm × 32mm, weighing approximately 23kg.
4. Intelligence
The combination of the weighing display controller of the electronic scale and the electronic computer utilizes the intelligence of the electronic computer to increase the weighing display control
The function of the device. Add reasoning, judgment, self diagnosis, adaptability, and self-organization to electronic scales on the basis of their original functions
These are the electronic scales on the market today that use microcomputer based weighing display controllers and those that use intelligent weighing display controllers
The fundamental difference between electronic scales used in equipment manufacturing.
5. Comprehensive
The development law of electronic weighing technology is to continuously strengthen basic research and expand applications, expand new technological fields, and move towards adjacent areas
Penetrating disciplines and industries, integrating various technologies to solve problems such as weighing and measurement, automatic control, and information processing. For example, in terms of traffic
In the field of metrology, if a standard high flow measurement system is built according to traditional theories and methods, the price is quite expensive. if
By using the weighing method, also known as the mass flow method, as long as the weight and time measurements are accurate, the problem of measuring large flow rates can be easily solved.
For some commercial electronic pricing scales, only having weighing, pricing, display, and printing functions is far from enough. Modern commercial scales
The system also requires it to provide various sales information, closely integrate weighing and management automation, and enable weighing, pricing, warehousing, and sales
Integrated sales management to achieve management automation. This requires electronic pricing scales to be networked with electronic computers, connecting the weighing system with
A computer system forms a complete integrated control system.
6. Combination
In the industrial weighing and measuring process or process flow, many weighing and measuring systems also require composability, that is, measurement range
Waiting can be set arbitrarily; Hardware can make certain adjustments based on certain working conditions and environments, and hardware functions can be directed towards software
Exhibition; The software can be modified and extended according to a certain program; Input/output data and instructions can use different languages and bars
The code can communicate with external control and data processing devices.
