Main Functions and Design Scheme of the Lab Bench Control System:
1. Employed a closed-loop control system, collecting operational information via sensors and other acquisition systems. The data is then input into a computer via a data acquisition card, displayed there, and calculated according to control requirements. Subsequently, control signals are output, processed by the data acquisition card into signals recognizable by the executing elements, and finally, system control is achieved through the actions of the executing elements.
2. Utilizing a centralized computer control system with PLC hardware and the WINDOWS system as the software platform. During the signal acquisition process, we collect both digital and analog signals. Therefore, we first need to convert the analog signal data into digital signals that the PLC can process. After processing by the PLC, a portion of the output signals is then converted back to analog to control the experimental bench. This requires both A/D and D/A conversions. Hence, an integrated data acquisition card with both functionalities is employed to perform the A/D and D/A conversions.
