Abstract

The present invention provides a power monitoring serial communication method and system based on an optimized polling mechanism. By designing a communication connection mechanism, the present invention solves the problem that the master device can query the slave nodes sequentially regardless of whether the nodes are online or not. problem, greatly improving the polling efficiency and data transmission efficiency of online nodes; through the data polling priority mechanism, not only the node polling is prioritized, but also the data in the node is prioritized, effectively ensuring To ensure timely response to control tasks and high-priority data priority query processing; through the data query number limit mechanism in the node, it can effectively suppress the disadvantages of non-stop query of node items and inability to query subsequent nodes, ensuring the normal polling of all node data , which improves the effectiveness of node data; through the above mechanisms, it ensures that the data of all nodes can be quickly and effectively queried, which greatly improves the reliability of data collection.

Description

technical field [0001] The invention relates to the technical field of power monitoring, in particular to a power monitoring serial communication method and system based on an optimized polling mechanism. Background technique [0002] With the development of modern technology, the degree of informatization of power automation equipment is getting higher and higher, and having a network communication interface has gradually become a necessary requirement. In the power monitoring system, the equipment needs to support multiple communication methods. The RS485 serial communication bus has been widely used because of its advantages such as long transmission distance, low cost, easy deployment, and support for multi-node communication. The RS485 serial communication bus is connected in a hand-in-hand manner. There can be as many as dozens of terminal equipment nodes on the bus, and the node data can be collected in time, and the operation commands can be issued and executed quick...
