1. The miniaturization is small in size, low in height, and light in weight, that is, small, thin, and light. In recent years, the newly developed electronic platform scale structure fully reflects the development direction of small and light. For low-capacity electronic platform scales and electronic axle scales, a thin or ultra-thin circular load cell can be directly embedded in the blind hole of the bottom surface of the steel plate or aluminum plate and the outer diameter of the load cell to form a low-profile scale. Body structure, the number and position of load cells are determined by the rated load and mechanical requirements of the scale. The steel plate or aluminum plate is the table top of the scale body. The load cell is both the sensing element and the bearing fulcrum, which greatly reduces the structure of the scale body and reduces the active connection, which not only reduces the cost, but also improves the stability and reliability. Sex. For medium or large-capacity electronic platform scales and electronic ground scales, thin-walled steels with square or rectangular closed sections have been used, and parallel rows of queues are welded into a single bamboo-plated structure scale body, and four load cells are respectively Installed in the slits at both ends of the two thin-walled steels outside the Zui, the fixed support installed on the load-bearing point of the load cell is the bearing fulcrum of the scale body, which reduces the bearing force transmission mechanism and saves the height of the scale body. It is a very promising scale structure. For large electronic platform scales, the finite element method can be used for the calculation of equal strength and stiffness, and the profiles with high bending rigidity and light corrugated sandwich steel plates are used.

2. Modularity For large or very large carrier structures, such as large static and dynamic electronic truck scales, modules of standard structure of several lengths have been adopted, and splits are combined to produce new varieties and specifications. Scale body structure. It not only improves the versatility, interchangeability and reliability of the products, but also greatly improves production efficiency and product quality. At the same time, it also reduces costs and enhances the market competitiveness of enterprises.
3. Integration For some types and structures of electronic scales, such as small electronic platform scales, special scales, portable static and dynamic electronic axle scales, static and dynamic electronic rail scales, etc., can be achieved with scales and load cells, rails and weighing The sensor, the rail scale body and the railway line are integrated.
For example, the portable static and dynamic electronic axle scale integrated with the scale body and the load cell is made of hard aluminum alloy thick plate. The structural principle is an aluminum alloy plate strengthened by solution heat treatment, or four cantilever beam type load cells are respectively formed by drilling and milling grooves at four corners; or a plurality of symmetric blind holes are milled on the bottom surface of the aluminum alloy plate. An integral shear beam type load cell is formed with the blind groove. This makes the scale body and the load cell combined into one, that is, the aluminum alloy plate is both a scale body surface and a large plate type load cell. For example, the 10t portable dynamic electronic axle scale of the latter structure has a size of 720 mm × 550 mm × 32 mm and a weight of about 23 kg.
4. The weighing display controller of the intelligent electronic weighing instrument is combined with the electronic computer to increase the function of the weighing display controller by using the intelligence of the electronic computer. On the basis of the original functions, the electronic weighing instrument adds functions such as reasoning, judgment, self-diagnosis, self-adaptation and self-organization. This is the electronic weighing instrument and the intelligent weighing display control using the microcomputerized weighing display controller on the market today. The fundamental difference between the electronic weighing instrument.
5. The development law of comprehensive electronic weighing technology is to continuously strengthen basic research and expand application, expand new technology fields, penetrate into adjacent disciplines and industries, and integrate various technologies to solve weighing measurement, automatic control, information processing, etc. problem. For example, in the flow metering profession, if a standard large flow measuring system is constructed according to conventional theories and methods, the price is quite expensive. If the weighing method, mass flow method, is used, the measurement of the large flow rate will be solved as long as the weight and time are accurately measured. For some commercial electronic pricing scales, it is not enough to only have the functions of weighing, pricing, display and printing. Modern commercial systems also require it to provide various sales information, and closely combine weighing and management automation. Heavy, pricing, storage, sales management integration, to achieve management automation. This requires the electronic pricing scale to be networked with the electronic computer, and the weighing system and the computer system form a complete integrated control system.
6. Combination In the industrial weighing measurement process or process flow, many weighing measurement systems also require composability, that is, the measurement range can be arbitrarily set; the hardware can make certain adjustments according to certain working conditions and environment. The hardware functions are developed in the direction of the software; the software can be modified and expanded according to certain programs; the input and output data and instructions can use different languages ​​and barcodes, and can communicate with external control and data processing devices.
Third, the conclusion of China's electronic weighing instrument to enter the international market. Participate in international competition. It is necessary to implement the international recommendations formulated by the international legal metrology organization and to have international-level technology and equipment and to have an international level of quality. This requires enterprises to take technology as the guide, quality as the center, and management as the basis, and strive to improve the level of manufacturing technology and manufacturing technology, and stabilize product quality. Enhance the competitiveness of the international market.
