Research and Development of Intelligent Mobile Operation Platform Control System in Facility Cultivation Environment

In facilities environment，mobile platform as a carrier in equipment such as spraying and picking，due to the restrictions on working environment，real-time and accuracy of its control system have higher requirements.In order to improve efficiency and accuracy of operation，distributed control system based on CAN bus was presented.The system was divided into two parts.The master controller was in charge of collecting position information and control decision.Each function node realized steering，speed change and equipment control of mobile platform.Communication of whole system was designed based on ISO11783 standard.Through system communication ability test，results showed that intelligent control system of mobile operating platform could meet demand of facilities operation，and its performance was more stable and reliable.
