1. Introduction With the widespread application of automated processing technology, traditional product quality monitoring methods can no longer meet the requirements of high-speed data acquisition and real-time tracking display. The automation requirements of product quality monitoring systems are becoming increasingly stringent. Configuration software, as a general-purpose monitoring software platform, has a series of advantages, such as shortening the development cycle of automated software, enhancing the robustness of software products, and significantly improving economic efficiency. However, the continuous, slow-changing process monitoring characteristics of configuration software make it difficult to meet the requirements of high-speed product quality monitoring systems. High-speed data acquisition and real-time data processing are two key technical problems that urgently need to be solved. This paper introduces a new approach to achieving high-speed product quality monitoring based on Kaiwu 2000 configuration software. This approach not only demonstrates the ease of use of configuration software but also effectively meets the application requirements of the monitoring system, including motion control, real-time high-speed data acquisition and display, report statistics, historical query, and access control. 2. Overall Scheme Design The product quality monitoring system consists of two parts: a hardware system and a host computer software system. It needs to handle issues such as motion control, high-speed data acquisition, real-time data display, and historical data query. The hardware system consists of a host computer and a slave computer. The lower-level computer consists of a workbench, PLC, frequency converter, motor, rotary encoder, and product quality sensors. The PLC serves as the monitoring center, responsible for receiving instructions from the upper-level computer to complete motion control and real-time data acquisition. Its block diagram is shown in Figure 1.

The upper-level computer software system consists of Kaiwu 2000 configuration software and a data processing module, with Kaiwu 2000 configuration software as the core. Modules communicate using messages and DDE. The Kaiwu 2000 configuration software consists of a development environment, a runtime environment, and communication drivers, which are responsible for completing engineering development, runtime data interaction, and real-time data communication functions, respectively. The data processing module completes functions such as real-time display of data histograms, report statistics, and data query. Its block diagram is shown in Figure 2.

High-Speed ​​Data Acquisition High-speed data acquisition includes the PLC acquiring product quality sensor signals at high speed and transmitting the acquired data to the host computer at high speed. To ensure high-speed, stable, and uniform PLC data acquisition, the product quality sensor signals are acquired through the PLC interrupt program. The acquisition period is set to 10ms, and the data in the same acquisition interval is filtered and averaged. This meets the requirements of sampling speed and sampling accuracy, laying a good foundation for subsequent data processing. To improve communication speed, the data requiring communication with the host computer is centralized in a single data register segment of the PLC, allowing all critical data to be obtained with a single communication instruction. Experiments show that at 19200 BPS, a single communication operation takes approximately 100 ms. Generally, the execution time for one interval in product quality monitoring is around 300-5000 ms, ensuring no data loss. Furthermore, to meet reliability and scalability requirements, data buffering technology is employed in the PLC program, guaranteeing no data loss even with a minimum interval execution time of 25 ms during product quality monitoring, effectively satisfying the communication speed requirements. 4. Real-time Data Processing Data acquisition is completed in the communication driver section of the Kaiwu 2000 configuration software, while real-time data display is completed in the data processing module. This necessitates timely transmission of data acquired in the Kaiwu 2000 module's communication driver to the data processing module. Based on commonly used inter-module communication technologies and considering the requirements of stability and reliability, the message communication method widely used in the Windows system was adopted. The transmission process is handled by the Windows system, offering advantages such as timeliness, stability, and reliability. A shared data structure is defined in the Kaiwu 2000 module and the data processing module. When the Kaiwu 2000 module receives the latest product quality sensor signal, it transmits relevant data, such as the current status information of the lower-level machine, to the data processing module via message, enabling it to complete subsequent functions such as real-time data histogram display and storage/retrieval. Experiments demonstrate that the data histogram accurately tracks the sampling signal of the product quality sensor, meeting a series of data processing requirements. 5. Conclusion Based on the above-mentioned technical solution, excellent results have been achieved in the high-speed product quality monitoring system. This verifies the correctness of the high-speed product quality monitoring scheme proposed in this paper. This paper uses Kaiwu 2000 configuration software as the core tool, comprehensively considers the requirements of high-speed product quality monitoring systems, and solves the technical problems of high-speed real-time data acquisition, high-speed real-time data transmission, and high-speed real-time data display. It effectively meets the requirements of high-speed product quality monitoring, expands the application scope of Kaiwu 2000 configuration software, and has certain guiding significance for the development of automated monitoring systems that require motion control and high-speed data acquisition.
