CMTDP, a wireless transparent transfer protocol based on UDP, was proposed for the remote intelligent monitoring system of construction machinery. The architecture of CMTDP was presented. The four key technologies of CMTDP were described, in which the transfer modes were matched online and optimized dynamically with the transmission data types and the transmission channel states. The test results of a practical application on concrete pump verify that CMTDP can satisfy the requirements of construction machinery on data transmission performance, transmission data types, monitoring scale and cost. The test results also show that the implementation of CMTDP does not need the support from the routing node in wireless network.

面向工程机械远程智能监控系统,提出一种基于UDP的无线透明传输协议CMDTP。给出了CMDTP总体体系结构,论述了CMDTP传输模式与传输数据类型、传输信道状态在线动态匹配寻优的四项关键技术。基于混凝土泵车的实际应用测试结果表明,CMDTP在数据传输品质、传输数据类型、监控规模和成本方面均可满足工程机械远程智能监控的要求,且该协议的实现不需要得到无线网络中路由节点的支持。
