英文摘要：

Traditional on-site task assistant pattern can＇t satisfy the dynamic and complex information requirement of mobile technicians.To tackle this problem,wearable computer and wireless sensor were introduced to the maintenance task site.Firstly,a special wearable computing system and an on-site task assistant pattern based on wearable computing was introduced.Secondly,implementation challenges of application structure constructing for this pattern were analyzed.Thirdly,for some key methods,the methods of extended Petri net and domain ontology design were proposed which was used to describe application function module.The domain structure analysis and Petri net mapping were put forward to generate layered colored Petri net.Assistant construction process of application structure based on ontology reasoning and transitions substitution was also realized.Finally,the application instance and analysis were also discussed.
