Embodiment

[0043] This embodiment is an IEC104 protocol analysis system based on an event-driven mechanism, such as figure 1 As shown, it includes a substation 1 and a master station 2 connected by a transmission channel, and an event-driven framework 3 is set between the substation and the master station. The event-driven framework includes an event source response module 4 and an event processing module 5. The substation is connected to the event source response module, the event source response module is connected to the event processing module, and the event processing module is connected to the master station;

[0044] Event source response module: monitor and respond to the network, information changes and fault conditions of the transmission channel between the substation and the master station in real time, and trigger the event processing module accordingly;

[0045] Event processing module: Analyze the network, information changes or fault conditions, send out the corresponding proc...

Abstract

The invention relates to an IEC104 protocol parsing system and method based on an event driven mechanism. The problems of poor flexibility, numerous uncontrollable factors, difficult debugging, running disorder, long thread waiting time and crash of the existing IEC104 parsing system are solved. The system comprises a slave station and a master station, an event driven framework is arranged between the slave station and the master station, and the event driven framework comprises an event source response module and an event processing module. By capturing a network layer, an information layer and a fault processing layer event change, event processing is performed. Therefore, there is no need to wait for the arrival of data circularly at any time during the processing, and in the case of the arrival of the data, the response module is automatically triggered, and the data are processed by the processing module, so that the working flexibility is good, and interaction with users is convenient. Parsing is performed based on even driven, thereby not only greatly reducing the requirements for the CPU and the internal memory, but also ensuring stronger flexibility, instantaneity and stability.

Description

Technical field [0001] The present invention relates to the technical field of a power dispatch automation communication protocol, in particular to an IEC104 protocol analysis system and method based on an event-driven mechanism. Background technique [0002] With the introduction and gradual deepening of smart grids, especially the large-scale access of new energy, the power system is required to have the characteristics of strong real-time, high reliability, strong data capacity and high degree of intelligence. Power dispatch automation system is the core of power system operation, and the quality of data communication controls the lifeblood of dispatching system intelligence. [0003] The IEC104 protocol has unique advantages due to its transmission medium being the Internet. As a key link of the power dispatch system, its high efficiency and stability have always been the goal pursued by people. The existing IEC104 protocol generally adopts a sequential, associated, and proces...
