| The rapid development of the Internet of Things(IoT) technology achieves the connection between things, and promotes the development of intelligent things. There is an outstanding problem, which is the installation, maintenance, and inspection of on-site terminal equipments, existing in all IoT application systems. The current situation is each IoT application system independently develops its own solution for the problem, resulting in less generality and reusability. Therefore, the main work of this thesis is as follows:Firstly, in the context of IoT application approach, analyze the on-site equipment installation, maintenance, and inspection work processes and determines an appropriate definition of task. Task is a person or device at the specified time and place, referring to a certain standard, carries out a series of activities in the equipment installation, maintenance, and inspection in accordance with a prescribed method. According to the current rules of on-site device operation, combined with modern information technology, determine the task-distribution-acceptance model and study the acceptance strategy of task, aiming at achieving standard operation and effective data sharing.Secondly, study the achieving technologies of tasks related on-site operations. The mapping mechanism of interactive dynamically generated object is determined by analyzing the type of data. Task interface dynamically generates through improving on TRIDENT layout strategy. Through the analysis and comparison of several currently frequently used identification technology, combined with herein specific application scenarios, choose the use of two-dimensional code technology and short distance communication technology to ensure the operator reaches the scene, and design the adapter to enable the usage of different identification technology. By customizing the application layer protocol, improve the reliability of the communication task to ensure the integrity and accuracy of a single task list download.Thirdly, realize the task-distributing-acceptance model at mobile terminal. It includes task download, task resolve and task dynamic display. When task finished, task results will be uploaded for server acceptance.Finally, apply the task-distribution-acceptance model to the development of the intelligent special equipment inspection system. The work of design, implementation and testing are carried out. With analyzing the test results, the intelligent special equipment inspection system has met the basic needs of users. In the performance, it can be used concurrently and t has a lower probability of errors. Therefore, the task-distribution-acceptance model has practical significance of application research. |
