Problems solved by technology
[0004] The data of ground observation stations have high reliability, but as far as China is concerned, the spatial distribution of observation stations is obviously discontinuous, showing a state of denseness in the east and sparseness in the west, which has a great impact on the quality of grid point data based on ground observations. influences
[0005] In the existing technology, when predicting whether a fire will occur in the area based on the temperature, it is usually judged according to the current temperature, or the difference between the temperature data sent by the meteorological satellite and the current temperature is used to make a judgment. The determined data is inaccurate due to temperature fluctuations; at the same time, in the process of data transmission, based on the existing architecture, data forwarding and control cannot be separated, resulting in slow system updates when the system is upgraded or new applications are added; It can reflect the possibility of fire occurrence and whether the event is urgent

The invention provides a fire hazard monitoring early warning method based on temperature data in power grid operation. The method comprises the following steps that: aiming at a province GIS (Geographic Information System) map, constructing a vectorization grid, and associating the temperature data in each area with the grid; and according to the temperature data of each meteorological monitoringpoint and current-day temperature data sent from a meteorological satellite, carrying out fire hazard possibility prediction, and in addition, when the temperature data and the early warning data ineach area are transmitted, utilizing a software definition network to forward the data. In addition, a checking and regulation advice for a sensor can be given to improve meteorological monitoring accuracy.
Description
technical field [0001] The invention relates to the technical field of fire monitoring and early warning, in particular to a fire monitoring and early warning method in power grid operation based on temperature data. Background technique [0002] With the continuous in-depth application of grid meteorological data and the continuous improvement of the requirements for accurate data analysis, the existing point data format based on meteorological monitoring stations can no longer meet the increasing business application requirements. The power supply area of the power system has increased, and meteorological factors The impact on the power system is not on the surface, but reflected on the point. Generally speaking, the geographical scope of the forecast area is relatively large. The main factors affecting the operation of power grid equipment in each sub-area in the forecast area are temperature and rainfall in various places. Circumstances are very different. [0003] As...
