Abstract

The invention discloses the setting of LonWorks communication parameters and a detection and display system and a method of Mac data frames, and belongs to the field of the LonWorks bus communication parameters setting and the Mac data frame detection technology. The invention aims at solving the problem that the LonTalk protocol cannot be studied in depth for relying on network management tools for parameters configuration. All the input and the output terminals of a detecting unit, a first transceiver, a second transceiver and a third transceiver of a system in the invention are connected with a Lonworks bus. The method of the invention comprises the following steps; after three nodes are initialized, a first node sends out a message and the detecting unit starts to detect the bus level to capture a Mac frame. Then whether a second and a third nodes receive the message is detected. If a message is received, network variables data is displayed. If the message is not received, then No Data Received is displayed. The invention creates conditions for different transmission modes of messages and realizes the detection and the display of the Mac frames.

Description

technical field [0001] The invention relates to the technical fields of LonWorks bus parameter setting and MAC data frame detection. Background technique [0002] The existing LonWorks technology provides a powerful node development tool LonBuilder and a network management tool LonManager, these tools can simplify the process of node development and networking, but due to the existence of network management tools and NSS bundlers, messages between nodes The setting of addressing and transmission mode is simplified to parameter configuration and graphical design under the operating software, which largely conceals the essence of message communication between nodes and hinders the learners of this technology from understanding the LonTalk communication protocol. Contents of the invention [0003] The present invention aims to overcome the unclear process of message transmission and data framing between nodes due to the dependence on the use of network management tools for va...
