Grasping the development direction of the instrument is grasping the future of the weighing instrument

I have always believed that weighing instruments are information-based electronic products. Faced with the changes in the new situation of scientific and technological progress, enterprises keep abreast of the development trends of the electronic industry and adjust their technical strategies in a timely manner, which can not only reflect the wisdom of the enterprise, but also exert the power of the enterprise. When the structure of a weighing instrument is determined, the performance of the weighing instrument will be determined by the weighing instrument. It can also be said that the future of the instrument determines the future of the weighing instrument. From the perspective of electronic information, the weighing instrument is the soul of the weighing instrument. Planning the development of the weighing instrument from this point of view can be synchronized with the development of electronic technology. This article refers to some technical literature on computer applications and automated measuring instruments at home and abroad, and combines personal experience to discuss the development path of weighing instruments with colleagues in the weighing industry.

1. PC-based weighing technology flexibly realizes user-customized weighing systems

Traditional weighing instruments are still limited to receiving analog signals for shaping and amplification, digital conversion, data processing, and display of weighing results. Most of the PCs used are also used as terminals or even peripherals (such as some regulations in the national standard, which limit the effectiveness of PCs). Therefore, the biggest common feature of weighing instruments provided by various manufacturers is the instrument defined by the manufacturer. They are just products that manufacturers want, and users can only communicate with the instrument according to the manufacturer's regulations, and even a button or a symbol cannot be changed. Traditional instruments lack flexible capabilities such as expansion and extension. Users pay a high price, but it is still difficult to meet the measurement and control tasks they need. Now the information society requires that the performance of weighing instruments is getting higher and higher and the functions are becoming more and more diverse. Fortunately, computers have the ability to adapt to such complex tasks, so PC-based measurement control systems (PC-Based Measurements) have emerged. As long as the data acquisition module, input and output I/O, peripherals and PC are organically combined, the expert in converting general-purpose computers into measurement control systems has been completed. This model is called a weighing instrument defined by the user. Today, PCs have entered the era of multi-core processors. Using their multi-tasking, multi-threading, high speed, and good hardware and software docking characteristics, weighing control systems with computers as the core are particularly flexible, excellent, and powerful. PC-based measurement technology has significant advantages such as modular I/O, online processing and analysis, real-time data visualization, efficient data storage, and dynamic report generation.

1. Modular I/O to meet various needs

PC-based measurement provides good flexible options and is easily integrated with existing systems such as process instruments, programmable logic controllers (PLCs) and single-loop controllers. It uses standard buses such as PCI Express, PXI Express, USB, wireless and Ethernet and internal plug-ins to meet different customer needs, seamlessly connect hardware and software, and achieve fast measurement and user-defined processing, analysis and display, with unparalleled cost-effectiveness.

2. Powerful online signal processing and process analysis capabilities

Traditional weighing instruments focus on putting measurement functions first, while data processing and analysis are placed in a secondary position, and the methods are relatively backward and cumbersome. For example, data analysis is often performed by copying data offline. Online processing and analysis will push automated weighing to a new level. Using the advanced computing technology of PC to process the acquired signals in real time and analyze the signals online, it greatly reduces the time of manual data search and offline analysis.

3. Real-time data visualization

Choose a graphical programming language to establish a human-computer interactive graphical interface for PC-based instruments to realize real-time data visualization, so that the operator can establish a friendly and close interactive relationship with the system, so that "everything is in vision and everything is under control". It is not difficult to make a good human-computer interactive interface. With the help of intuitive graphical programming software, a technician without any computer programming experience can easily convert a computer into a user-defined measurement system through interactive control windows, assigning hardware codes, configuring bus communication options, etc., and complete the construction analysis and visualization functions required by the application.

4. Leading high-efficiency data storage

With the continuous advancement of PC technology, it can always provide leading data storage capacity and efficiency. Statistics show that the massive capacity of hard disks (now up to terabytes of storage) and read and write speeds have increased 100 times every decade, and the cost has also decreased at the same rate, constantly creating new records in data reading and writing. Moreover, different I/O interfaces of PC enable operators to interact with data randomly or offline at will.

5. Generate reports quickly and accurately

Report generation is a critical link in data analysis. PC-based instruments can accurately call calculation functions and preset data processing software to automatically complete the entire process from measurement, processing, control to report generation. While improving quality, it saves time.
