Compared with the ordinary milling machine, its outstanding characteristic is that it can milling out the shape rule and the vertical circular pit with the edge. The main working device of this equipment is driven by hydraulic pressure. Therefore, the hydraulic system is the machine. At the same time, the electronic control system is a necessary condition to ensure the coordination of the power and hydraulic system of the whole machine. It is also a necessary condition to ensure the performance of the operation and improve the efficiency of the operation. The main work of this paper is to carry out the design concept of high efficiency and energy saving, design and develop the hydraulic system and electronic control system that meet the function and performance requirements. The main work of this paper is as follows:
1, the functional requirements and performance requirements of the milling machine are analyzed, and the requirements for the hydraulic system of the operation device are defined, and the design objectives are clearly defined.
2, a lot of literature and data about hydraulic and electro-hydraulic control are consulted. From the design of hydraulic support system that meets the requirements of each system, the design of the hydraulic system is completed through synthesis, and the calculation and selection of important components in the system, such as hydraulic pump, hydraulic motor, hydraulic cylinder and auxiliary components, are carried out.
3, a detailed analysis is made on the control support system of the milling planing device for the hydraulic system of the rapid chassis round pit milling planer. The independent system of the hydraulic cylinder is controlled by a reasonable and energy-saving variable pump. The output power of the engine is fully utilized, and the efficient operation of the milling planer is ensured.
4, in view of the limitation of the actual conditions and the importance of the relevant parameters of the pump control cylinder system, the simulation modeling and analysis of the hydraulic milling planer and the waste lifting system are selected, and the influence of the internal and external parameters on the response speed and the related performance of the system is discussed, and the simulation verification is carried out through AMESim.

6, component selection and simulation experiments of the electronic control system have been completed.
Through the design, calculation, simulation and modification, the design of the hydraulic system and electronic control system can meet the function realization and automatic control requirements of the fast chassis round pit milling planer. It has the characteristics of practical, efficient and energy saving.
