Abstract：Aiming at the existing grafting machine control system using punch control wiring complexity，debugging cumbersome andother isses，put forward agrafting machine based on EtherCAT bus control of four-station paralelcontrol method.Analyze the overallstructure and working principle of the grafting machine，determine the paralelcontrol system schemeand hardware selection.Analyze and calculate the combination andmatching of each hardwarecomponent，the selectionof stepping motor and servo motor，and optimize their performance in work.Adopt the combination of EtherCAT bus communication protocol andI/O control equipment tolcontrol the steping motor，servo motor and pneumatic components，to realize the synchronous operation of the upper seedling cutting， docking and spraying，seedling curing and flexible seedling module，andto ensure that the moduleoperates independentlyandcoordinates theoperation.Reduce thecomplexityof thecabling through theEtherCATbustoreduce the lineinterferenceanddebuggingworkloadinthetraditional control system.Atthesametimetoimprovethe stabilityof the systemandreal-timeresponse capability；design HMI human-computer interfaceto monitorthe operating status of the equipment and parameterregulation，HMI human-computer interface real-time displayof the working statusof each module，theoperatorcan through the intuitive graphical interface，to quickly grasp丨theoperation of the equipment，and test verification.The test results show that：grafting eficiency is 587 plants/h，grafting survival rate of 94.5% ，the use of EtherCAT bus control can greatly reduce wiring，simplify the debugging work.
