The invention discloses a hydraulic elevator control system and method, and belongs to the technical field of petroleum drilling machine devices. The system comprises a first reversing electromagnetic valve used for controlling the elevator to be opened/closed, a control oil way used for controlling the elevator to be opened/closed through the first reversing electromagnetic valve, and an execution oil cylinder used for achieving driving through the control oil way, and the elevator is controlled to be opened/closed through the execution oil cylinder. According to the hydraulic elevator control system and method, the problem that a traditional hydraulic elevator usually adopts a mechanical arm or manual operation mode is solved, the elevator opening and closing efficiency is effectively improved through hydraulic control, the automation effect is better achieved for petroleum drilling field operation, and the operation efficiency is higher. 本发明公开了一种液压吊卡控制系统及控制方法，属于石油钻机装置技术领域；该系统包括用于控制吊卡开启/闭合的第一换向电磁阀，以及通过第一换向电
