摘要：In the current hydraulic field, there is a phenomenon that “many kinds of proportional valve exist, so the same kinds of proportional valve controller are required”. In order to change this unreasonable situation, a research direction is proposed to develop a general proportional valve controller to fit a variety of proportional valve. The ratio of different functions can be realized by entering different control software and setting different parameters in the universal proportional valve controller. Through the communication between MCU and PC, PC is used as host computer to set, display and manage the parameters of proportional valve controller. The experiment shows that the controller has excellent flexibility, versatility, low installation and maintenance cost, high cost performance and it’s suitable for popularization and application.
