Main Functions and Design Scheme of the Lab Bench Control System:
1. Utilizing a closed-loop control system, information from the system operation is collected via sensors and other acquisition systems. The collected data is then input into a computer via a data acquisition card, where it is displayed and calculated according to control requirements. The control signals are output, processed by the data acquisition card into signals recognizable by the actuator, and finally, system control is achieved through the actuator's movement.
2. Utilizing a centralized computer control system with PLC hardware and a Windows software platform. During the signal acquisition process, we collect both digital and analog signals. Therefore, we first need to convert the analog signal into a digital signal that the PLC can process. After processing by the PLC, a portion of the output signals must then be converted back to analog to control the laboratory bench. This requires both A/D and D/A conversions. Hence, a data acquisition card integrating both functionalities is needed to perform the A/D and D/A conversions.
