Beschreibung
Zusammenfassung:	The invention discloses a hydraulic control system based on LabVIEW. The hydraulic control system comprises a hydraulic cylinder, a computer with LabVIEW, a proportional amplifier, a direction valve,a displacement sensor and a serial port communication device, wherein the computer sends a control current signal to the proportional amplifier through the serial port communication device, the proportional amplifier amplifies the current signal and then outputs the current signal to the direction valve, the direction valve receives the current signal output by the proportional amplifier to control the flowing direction and pressure of oil in the hydraulic cylinder, a hydraulic rod of the hydraulic cylinder moves, the displacement sensor detects the displacement of the hydraulic rod and sendsa voltage signal generated by displacement change of the hydraulic cylinder to the computer through the serial port communication device, and the computer receives the voltage signal and sends the control current signal to the
