Technical Field
The utility model relates to a bus state on-line monitoring system especially relates to an use independent communication cable to carry out the bus state on-line monitoring system of power line carrier communication.
Background
The traditional monitoring equipment in a non-bus form is generally used under the connection condition of short distance and few nodes, and the star connection using field communication buses such as RS485, CAN and the like CAN meet the monitoring requirement. However, the mainstream buses such as RS485 and CAN do not support the tree structure. The two buses, like MBus, support tree connections, but at a slow rate.
The bus monitoring equipment is generally used in the conditions of long bus distance and more monitoring nodes. Some traditional bus state monitoring schemes can directly transmit power carrier signals by utilizing bus copper bars (which are also power transmission lines), so that long-distance multi-node communication is realized. However, the bus is often used for supplying power to large-scale equipment, and the interference of the large-scale equipment can cause poor communication quality of power line carriers and even communication failure.
Therefore, for a bus monitoring system with a long distance and many nodes and complicated connection, a technology for high-speed and reliable communication of a large amount of data and a remote communication technology with various connection structures including a tree-shaped connection structure are required.
