| description | The invention discloses a hydraulic oil cylinder buffering control system and method of a working device and engineering machinery. An oil cylinder stroke sensor is additionally arranged, and the oil cylinder stroke percentage is calibrated; when it is detected that the oil cylinder enters the buffering stage, the system starts to enter buffering treatment from the buffering starting point to the tail end of the oil cylinder, the power, the rotating speed and the proportional valve opening degree are synchronously adjusted, parameters are adjusted according to the actual impact size, and buffering is achieved; according to the actual stroke percentage of the oil cylinder, the flow proportion, the valve element opening degree and power matching under different percentages are limited; parameter setting is carried out through the electronic monitor, and buffering parameter adjustability is achieved; an effective oil cylinder action recording and predicting model is established, oil cylinder operation data can b |
