Abstract: Servo pressure pulse testing equipment uses servo-hydraulic technology to build the model of hydraulic system. By improving measurement and control system, the equipment accomplishes signal acquisition, data processing and process control. LabVIEW and programmable logic controller (PLC) are used to carry out the hardware configuration and software development. The system can communicate between LabVIEW and PLC by virtual instrumentation software architecture (VISA) and run automatically in accordance with setting commands. Therefore, accuracy and performance of the equipment are improved.

 

Key words: programmable logic controller (PLC); LabVIEW; servo-hydraulic system; virtual instrumentation software architecture (VISA)
