With the rapid development of social, economic, and cultural development in China in recent years, we are no strangers to a wide variety of electronic weighing devices, even to the upgrading of these devices and electronic network systems for electronic measurement. There is also a certain pursuit and awareness. However, the practical application of the electronic weighing computing technology we currently use in electronic engineering is still only in a relatively primitive practice and method. The degree of intelligence of this electronic weighing instrument in life measurement means that China’s electrical appliances are intelligent. The degree of application is still far from the level required by modern science and technology, and the most common source of information that people are exposed to and used today is the intelligent network transmission product with modern technology, so if we do not focus on With the expansion of the electronic scale's intelligentization, as well as its design and application of optimized computer management, the rapid development trend of our buildings cannot meet the requirements of the contemporary society. Things that cannot keep up with social progress are bound to be eliminated.

1 Development Trends of Electronic Scales
After years of development, electronic scales have a wide variety of specifications and models, which are not only limited to weighing and pricing, but also can be used as a measurement and control unit for production process inspection systems. With the continuous application of electronic weighing instruments, Its application area is also constantly expanding. The intelligent electronic weighing instrument is an important point that every advanced individual must keep up with the times and the innovative research on these intelligent building applications can not only enable China’s computer measurement to enter a new era that is faster and more convenient. Innovations in calculation and measurement can also fully promote the overall progress of industries in various fields in China. However, it is obviously difficult to explain how to apply the innovation of electronic weighing instrument in real life, so we must learn from the principle of measurement itself, from the unit of measurement and the ontology of computing. By building members to start, only by doing this well can we achieve the purpose and goal of scientifically enhancing technology and conducting scientific self-exploration.
Miniaturization: Electronic weighing devices begin to develop in a small, thin and light direction. People's demand for electronic weighing devices has been increasingly developed in the direction of small size, low height, and light weight. In order to achieve miniaturization, the choice of electronic weighing materials There are special requirements, usually light weight and stiffness of hollow corrugated copper sheet and square closed-section thin-walled profiles.
Modularization: Modular combination makes great changes in the types and specifications of electronic weighing instruments, making electronic weighing instruments more versatile and reliable. At the same time, the use of modularity in the carrier, because of the use of one group or Or a combination of separate ways, effectively reducing the cost of electronic weighing, and to a large extent improve the production efficiency.
Intelligentization: With the development of information technology, electronic weighing instruments can be combined with a computer or a computer for weighing can be developed. This can effectively use the intelligent function of a computer to increase the display control function and make the electronic weighing instrument. In the original function to get a wider range of expansion.
2 Use and maintenance of electronic scales
Electronic scale is a kind of electronic weighing instrument. It is mainly used to weigh and measure objects. In the process of weighing, if the measurement is not accurate, it will affect the user's own interests. In the process of using electronic scales for weighing, There will be some problems, mainly due to the use of methods and improper daily maintenance, which have seriously affected the accuracy of the measurement. Therefore, when using electronic scales, it is necessary to have some basic knowledge to ensure the correct use of the method. When using electronic scales for weighing and weighing, the electronic scales should be placed on a stable and fixed table. The scales should not be placed on objects that have nothing to do with the so-called objects. Tilting or shaking of electronic scales will affect the accuracy of measurement. So maintaining the level of electronic scales is the primary factor. When not in use, the electronic scale should be properly stored, and the power supply should be turned off to avoid placing heavy objects on the electronic scale and placing it in a ventilated position. Handle it gently and strictly without strong impact. There is a mercury bubble on the panel of the electronic scale. In order to ensure the level of the electronic scale before weighing, it is necessary to observe whether the mercury bubble is in the middle position. If deviation occurs, the electronic scale is not flat, then it needs to be adjusted.
3. The basic method of detecting electronic weighing instrument failure
The basic method of electronic instrument failure confirmation is to use a one-by-one elimination method. Because the electronic scales mainly include scale bodies, sensors, junction boxes, meters and other components. So first determine whether the fault occurred in the scale body or in the meter section.
(1) Turn off the power and disconnect the meter from the scale;
(2) Connect the meter with the simulator to check if the meter is working properly;
(3) If the meter is normal, disconnect the sensor wires one by one to find the fault sensor;
(4) Measure the input/output impedance of the sensor with a high-precision multimeter. Any one of them is abnormal, indicating that the internal circuit is faulty;
(5) Measure sensor no-load output: >+5mV or <- 0.5mV are all sensor zero error;
(6) The output when measuring the load of the sensor: >+20mV are all sensor failures;
(7) Measure the sensor's insulation resistance (<200 MΩ): any color line and sensor surface and shield and sensor surfaces.
4. Considerations for maintenance and maintenance of electronic scales
In order to allow your weighing system to work stably for a long time, please do the following maintenance regularly.
(1) Check for excessive wear of sensors, connectors, and limit devices;
(2) Whether there are debris around the sensor connector and at the bottom;
(3) Check the clearance between the support bolt and the top plate;
(4) Check the number of limit bolts and the gap between them and the sensor;
(5) Check whether the junction box is sealed and whether the various wires are connected firmly;
(6) Whether there is moisture or foreign matter in or around the junction box;
(7) Check if the instrument cables are damaged and fixed on the scale body;
(8) Check if the scale body moves freely;
Concluding Remark: In recent years, as China’s pace of reform and opening up has been gradually accelerating and its scope has become wider and wider, China’s social, economic, and cultural development has been in a period of rapid development. In this kind of favorable development environment, each country in China There has also been a clear and encouraging trend in the industry, of which the more innovative industry is the computer Internet. First, the development of computer networks has only appeared in the 21st century. This is a more diverse development industry, and the second is the new period. The computer metrology work requires the introduction of new science and technology and new scientific equipment. Therefore, if the intelligence of electronic weighing instruments is to be applied appropriately in various fields, it will be necessary to set aside the dependence on these externally powerful conditions. The establishment of a better management style within itself will effectively achieve the goal of becoming bigger and stronger in the interior and establishing a good image in the outside. Only in this way can our intelligent electric building application work have the driving force of development that will never be exhausted.
