Study On Communication System Of Road Construction Based On Multi-Agent

The multi-agent technique is putting into practice wider and wider as the fully development of multi-agent technique and the academic research concerning multi-agent. In recent years, many a foreign researcher has begun to try to study new products of mechanical group about multi-agent. And China has listed the research about application of multi-agent system into the National 863 Plan. Supported by the national 863 Science Plan of China-Imlpementing Scheme on Intelligent Machine Group(Grant No.2001 AA422011)and Intelligence and Manufacture Imformatioization of the Construction Machinery of Road(2003AA430030), the communication system of asphaltum-concrete road construction is systematically and thoroughly studied.The special distributed-layered tree control architecture of a mechanical group for high-level road constructing is set up to adapt to the characteristics of high-level road, the communication architecture is founded based on blackboard system, and a special composite communication mechanism is constructed correspondingly. At the same time, a scheme of wireless communication is designed, and relevant hardwares required are prepared. All what the steps are taken to ensure that our multi-agent system may finish its task with higher efficiency and lower cost.The main work includes:1. The intelligent construction machinery is introduced, and the intelligent control process of asphaltum-concrete road construction is described. The special distributed-layered tree control architecture of a mechanical group for high-level road constructing is set up to adapt to the characteristics of high-level road, and all control architecture of agents are mainly analyzed as well as their functions.2. Agent communication methods, communication modes and communication models are introduced in the paper, and the theory of blackboard system is imported in the construction machinery. The communication structure of the construction machinery is constructed based on the blackboard system and information flow also. The blackboard and the knowledge resource are also designed in the blackboard system.3. The special communication mechanism, which makes use of two communication methods of direct routing and routing by signal propagation, is estimated to accommodate to the system architecture. Meanwhile, a scheme of wireless communication is designed, and relevant hardwares required are prepared. All what the steps are taken to ensure that our multi-agent system may finish its task with higher efficiency and lower cost.
