The invention provides a monitoring method and system based on an IEC 104 protocol. The method comprises following steps of building TCP connection of a master station, a slave station and a monitoring system; judging message types, wherein the message types comprise uplink messages and downlink messages; if the messages are uplink messages, judging whether the response of the master station is correct or not; if the messages are downlink messages, judging whether the response of the slave station is correct or not; if the incorrect response times of the master station or the incorrect response times of the slave station exceeds 5 times, sending a warning signal; and if the response of the master station and / or the slave station is correct, storing the corresponding uplink messages and / or downlink messages. According to the method, the incorrect response times of the master station or the incorrect response times of the slave station are respectively accumulated, when the incorrect times exceeds 5 times, the warning signal is sent; a monitoring worker can timely search and process device faults according to the warning signal; bad effects such as network congestion can be avoided; and the monitoring method can be used for solving the technical problem that the device faults cannot be fed back timely in the prior art.
Description
technical field [0001] The invention relates to the field of electric equipment network communication, in particular to a monitoring method and system based on the IEC104 protocol. Background technique [0002] With the rapid development of my country's economy and the continuous improvement of people's material living standards, people's demand for electricity is increasing, which puts forward higher requirements for the quality, reliability and safety of power supply of the power grid. At present, my country plans, analyzes and controls the power system through the power grid dispatching automation system, so as to ensure the uninterrupted supply of stable and qualified electric energy to users. The power grid dispatching automation system is composed of various monitoring and dispatching automation hardware and software in the power system. According to its functions, it can be divided into the following four systems: information collection and command execution subsystem...
