基于专利计量的设施蔬菜传感器技术研究态势分析

Research Situation Analysis on Sensor Technology of Protected Vegetable Based on Patentometrics

为了解全球设施蔬菜传感器技术的发展态势,本文以设施蔬菜传感器技术的相关专利作为研究对象,对该技术领域的发展趋势、技术分类、专利布局、研发力量、主题演化等进行了分析。主要结果如下:全球设施蔬菜传感器技术的发展可以分为萌芽期、波动发展期、平稳发展期、快速发展期四个阶段;中国是全球设施蔬菜传感器领域最大的技术输出国;设施蔬菜传感器领域重点国家的技术布局覆盖面都较广,但是各有所侧重;设施蔬菜传感器领域专利申请最活跃的群体是公司,其次是大学;我国高申请(研发)量的申请(发明)人很多,但是影响力欠佳;重点申请(发明)人之间既存在技术交叉,又各自有独特之处;该领域发明人之间的合作主要是研发团队内部的合作,跨团队合作行为很少;全球在该领域的专利研究大致包含温室/大棚综合、监测/通信/控制技术等11个主题,不同发展阶段设施蔬菜传感器领域的重点研发方向具有差异性,整体呈现出由数量少、集中度高向数量多、集中度低发展的趋势。

Agricultural Internet of Things is a new type of information integration technology.In order to understand the global development trend of sensor technology for protected vegetables,the related patents were taken as research object to analyze the development trend,technology classification,patent layout,research and development strength and theme evolution of this field.The main results were as follows.The development of sensor technology for protected vegetable in the world could be divided into four stages as germination,fluctuation development,stable development and rapid development.China was the largest technology exporting country in the field of protected vegetable sensors.The technology layout of main countries in the field of protected vegetable sensors covered a wide range,but each had its own emphasis.The most active groups of patent application in the field of protected vegetable sensors were companies,followed by universities.There were a lot of applicants(inventors)with high applications(inventions)in China,but their influence was not strong.There were technical cross between main applicants(inventors),and each had its own unique features.The cooperation among inventors in this field was mainly within the research and development teams,and there were little cross-team cooperation behaviors.The patent research in this field mainly included 11 topics,such as greenhouse integration,monitoring/communication/control technology.The main research and development directions in the field of protected vegetable sensors were different among different development stages,and the overall patents showed a trend of developing from a small number with high concentration to a large number with low concentration.
