[0002] The current hydraulic system control in industrial applications is mainly controlled by the combination of PLC, relay and proportional amplifier board. The PLC output signal controls the relay output switch signal, and the proportional amplifier board outputs proportional signal to drive the electromagnet. The entire electrical control system is based on the control cabinet and The installation of the console, if real-time monitoring of the operating status of the hydraulic system is required, it is necessary to install a computer and compile monitoring software. The control system of this method is more complicated, and the volume is large, the cost is high, the connection is complicated, and maintenance is difficult. Not suitable for applications with high space requirements
At present, the existing industrial controllers are mainly developed for construction machinery, with limited input and output channels, and it is difficult to achieve system-level expansion, which cannot meet the requirements of complex industrial field hydraulic systems.
