Abstract

The invention provides a real-time detection system and method of an industrial control system, wherein the system includes: a data measurement probe, a dedicated communication network, a detection computer, and an accurate timing system, which can measure the measured value data sent by the transmitter in the industrial control system , and the time when the actuator receives the output data from the controller, and calculate its delay time to obtain the real-time performance of the system. The present invention also provides a corresponding detection method. Through the system and method of the present invention, the quality of the industrial control system can be effectively evaluated, and it can be used as a means of anomaly detection to overcome the real-time problems of the industrial control system only through the data transmission rate. Disadvantages of assessment.

Description

technical field [0001] The invention relates to the field of industrial control systems, in particular to a system and method for detecting the real-time performance of an industrial control system. Background technique [0002] Industrial control systems require high real-time performance. For process control loops, the decline in real-time performance will lead to more serious hysteresis in the process control loop, causing damage to normal process control, such as severe overshoot and oscillation. For DCS (distributed control system), due to the existence of time-consuming links such as A / D conversion, D / A conversion, and software control algorithm execution, real-time performance may be affected; for FCS (fieldbus control system), due to the presence of fieldbus The impact of data transmission delay on real-time performance cannot be ignored. Detecting the real-time performance of industrial control systems, especially detecting the real-time performance of industrial c...
