Abstract

The invention provides a power monitoring serial communication method and system based on an optimized polling mechanism, and the method and system solve a problem that a master device can sequentially inquire slave nodes in a fool manner no matter whether the nodes are online or not through the design of a communication connection mechanism, and greatly improve the polling efficiency and data transmission efficiency of online nodes. Through a data polling priority mechanism, priority processing is carried out on node polling, priority processing is also carried out on data in nodes, and timely response of control tasks and priority query processing of high-priority data are effectively ensured; through an intra-node data query frequency limiting mechanism, the defect that node items are continuously queried and cannot be queried for subsequent nodes is effectively overcome, normal polling of all node data is ensured, and the effectiveness of the node data is improved; through the various mechanisms, it is ensured that data of all nodes can be inquired rapidly and effectively, and the reliability of data collection is greatly improved.

Description

technical field [0001] The invention relates to the technical field of power monitoring, in particular to a serial communication method and system for power monitoring 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 it has gradually become a necessary requirement to have a networked communication interface. In the power monitoring system, the equipment needs to support a variety of communication methods. The RS485 serial communication bus has been widely used due to its advantages of 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 quickly issued and e...
