    • The present invention relates to a communication network analysis apparatus in a multi-layered communication system and a method using the apparatus, and more specifically, to a communication network analysis apparatus in a building automation and control system, a communication method using the apparatus, and a protocol conversion method.A communication network analysis system according to the present invention is a BACnet MS/TP communication network analysis system including at least one BACnet MS/TP node connected to a BACnet MS/TP communication network and a BACnet visual test shell (VTS) for monitoring the BACnet MS/TP communication network. The system comprises a monitoring node for performing a first filtering on a frame received from the BACnet MS/TP communication network, configuring a monitoring frame by adding a monitoring frame header to the received frame on which the first filtering is performed, and transmitting a frame corresponding to a message created in the BACnet VTS to the BACnet MS/TP communication network; and a monitoring module for receiving the monitoring frame from the monitoring node, performing a second filtering on the received monitoring frame, outputting a result of the second filtering, transmitting a part of the monitoring frame on which the second filtering is performed to the BACnet VTS, receiving a message from the BACnet VTS, determining a destination address of the BACnet MS/TP communication network to which the received message is transferred, configuring an MS/TP frame on the basis of the received message and the destination address, and transmitting the configured MS/TP frame to the monitoring node.
    • 本发明涉及多层通信系统中的通信网络分析装置和使用该装置的方法,更具体地说,涉及建筑物自动化控制系统中的通信网络分析装置,使用该装置的通信方法,以及 一种协议转换方法。 根据本发明的通信网络分析系统是包括至少一个连接到BACnet MS / TP通信网络的BACnet MS / TP节点的BACnet MS / TP通信网络分析系统和用于监视 BACnet MS / TP通信网络。 该系统包括用于对从BACnet MS / TP通信网络接收的帧执行第一过滤的监视节点,通过向执行第一过滤的接收帧添加监视帧报头来配置监控帧,并且发送帧 对应于在BACnet VTS中创建的到BACnet MS / TP通信网络的消息; 以及监视模块,用于从所述监视节点接收所述监视帧,对所接收的监视帧执行第二过滤,输出所述第二过滤的结果,将执行了所述第二过滤的监视帧的一部分发送到所述BACnet VTS 从BACnet VTS接收消息,确定接收到的消息被传送到的BACnet MS / TP通信网络的目的地址,根据接收到的消息和目的地地址配置MS / TP帧,并发送 配置MS / TP帧到监控节点。
