Development of measurement and control applications to optimize the research, development, and testing sites for automotive drive system components.
In the research, development, and testing fields of automotive drive system components that we have seen so far, it is still common to encounter configurations where the control of testing machines, the control of test specimens, and the operation of various sensors and measuring instruments must be handled separately on different devices or screens. As a result: - The separation of control and measurement makes it cumbersome to reproduce test conditions and synchronize data. - Tests are sometimes conducted by multiple people, leading to low productivity. - After testing, it is necessary to organize, evaluate, and create reports from multiple data sets, which does not allow sufficient time for consideration and analysis. These issues are accepted as the "norm" in the field. Seagoat Co., Ltd. provides solutions to these challenges through an approach focused on the development of measurement and control applications. By combining software such as C#, LabVIEW, VC, VB, and Verilog-HDL with HMI, real-time control, and FPGA, we integrate the control of testing machines, test specimens, measuring instruments, etc., into a single application. This establishes control and measurement with high certainty and synchronization, creating an environment that allows for seamless automation of testing, data acquisition, evaluation, and report creation.

basic information
Based on software such as C#, LabVIEW, VC, VB, and Verilog-HDL, we build measurement and control applications by combining HMI, real-time control, and FPGA, integrating control and measurement into a single application rather than handling test equipment, specimens, sensors, and measuring instruments individually. With devices implemented with real-time operating systems like cRIO, we strictly manage control cycles in milliseconds and execute hardware-level parallel processing such as logical operations in nanoseconds using FPGA. This enables highly deterministic control and measurement that maintains processing timing even at cycles in milliseconds, and in some cases, nanoseconds.

Applications/Examples of results
Devices implemented with real-time operating systems like cRIO manage control cycles with precision in milliseconds and execute hardware parallel processing such as logical operations in nanoseconds using FPGAs. This enables high-determinacy control and measurement that maintains processing timing even at cycles of milliseconds, and in some cases, nanoseconds. For example, in performance testing of automotive drive components, it is necessary to acquire instantaneous torque and vibration data while making transient changes in rotational speed and torque at precise intervals. Through real-time control and parallel processing, control and measurement can consistently occur on the same time axis, ensuring high reproducibility of test conditions and reliability of data.
Detailed information
-
In the configuration after the introduction of our measurement and control application, we design it as an integrated system based on real-time and synchronization without separating control and measurement. We will build the system using applications based on embedded devices such as cRIO for real-time control and parallel processing. Control of the test equipment, control of the specimens, and signal acquisition from various sensors and measuring instruments such as torque, rotation speed, temperature, vibration, and power will be integrated on the same system. This enables: - Real-time synchronization of control and measurement - High precision in reproducing load conditions, including responsiveness and load fluctuations - Since it is an integrated design, measurement data is not dispersed and is saved in a single file As the operation screens and data files are consolidated, there is no need to switch between multiple PCs, allowing for a consistent process from test execution to data measurement, resulting in reduced workload and enabling reliable and reproducible test operations.
