中文摘要:信息物理融合系统(CPS)具有严格的实时性和空间约束,根据其事件驱动性,对CPS时空事件模型进行了描述,并依据精准农业的特点对CPS体系结构中的组成部件(物理世界、传感器、计算(控制)单元、执行器、计时器)建立了时空事件模型,并以精准农业大棚的洒水事件闭环过程为例对每一部件进行了分析,证明这些事件模型可以用于精准农业中的基本事件。

Abstract:Cyber-physical systems have strict real-time and space constraints, and event driven is one of its important characteristics. In CPS, events are composed of the change of the physical environment and object state, which form the closed-loop process of events trigger, perception, decision-making, control, then to events, and ultimately change the physical state of the object. This paper outlines some preliminary exploration of spatial-temporal event model of CPS, and then make a further study. According to CPS’ event-driven nature, spatial-temporal event model was described from time, space and observer, and established for major components of CPS based on the characteristics of precision agriculture (PA): the physical world, sensors, calculation (control) unit, actuators, and timer. Finally established spatial-temporal event model was validated by closed-loop process of sprinkler incident in precision agriculture, and it was proved that these events model can be used in PA. It turns out that spatial-temporal events in precision agriculture CPS are preliminarily discussed which lays the foundation for future research on event model applied to PA.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
