The invention discloses a controller for transforming start-up sequentially. The controller for transforming start-up sequentially comprises an oil circuit control valve, wherein the output end of the oil circuit control valve is connected with a hydraulic oil cylinder to form a circular oil circuit; more than one opener is arranged on an oil circuit between the oil circuit control valve and the hydraulic oil cylinder. According to the controller for transforming start-up sequentially, the openers synchronous with the hydraulic oil cylinder in action can supply instructions and execution to the action of other devices, so as to achieve multiple cylinders and multi-action automation of an oil circuit system. Moreover, the controller can achieve remote or space operation and control of an execution mechanism, can substitute for electric control or numerical control to realize automation on special occasions, so that not only is the requirement on performance satisfied, but also safety and economy are ensured. In addition, the controller for transforming start-up sequentially has the advantages of simple structure, smart combination, low manufacturing cost, capability of application under vile environments, simplicity and convenience for use and maintenance, no need for high-grade training before use and the like, and has very good application prospects.
