Description
Technical field
the invention belongs to construction technique field, weather station, relate in particular to a kind of portable split weather station of networking.
Background technology
the early stage weather station of the mankind Main Means changed that predicts the weather is to measure relative atmospheric pressure change, and because As time goes on the atmospheric pressure of different regions can constantly change, people can realize weather forecast by the relative variation of measuring air pressure.According to the mechanism of production of air pressure, usually use Pascal (Pa) as its absolute unit of measurement, air pressure is a most important index of the actual weather conditions of judgement.Generally, air pressure is high being considered to " weather is good " relatively, and air pressure is relatively low is considered to " bad weather ".Using sea level as reference zero point, and air pressure is 101325Pa.In general the normal variation scope of air pressure is 200 Pa, and atmospheric pressure descends with the rising of sea level elevation usually.Particularly, for mountain area, we measure local air pressure, are converted into the relative barometric pressure value as a reference point with sea level simultaneously.Generally on physics assert 10 meters of the every risings of sea level elevation, the atmospheric pressure about 100Pa that will descend.Therefore at first the forecast of weather needs to calibrate local sea level elevation.Force value after absolute calibration is a standard value that can be used to the comparison reference, under actual weather condition, the relative variation of atmospheric pressure of usining is feasible as the Changes in weather of weighing in the following short time, because atmospheric pressure also follows all the time in the variation of weather condition among continuous variation.
the related data provided according to Shanghai weather bureau, when air pressure, within half an hour lower than standard atmospheric pressure 200-300 Pa the time, precipitation probability is about 80%, and in the situation that air pressure in high-order, historical precipitation probability is less than 20%.We have produced a set of specially for the relative variation of the air pressure change algorithm that predicts the weather, this algorithm is exactly: when half an hour, the internal gas pressure fluctuation surpassed 300Pa, the precipitation probability of extrapolating is 83%, and, when air pressure fluctuation is less than 100Pa, precipitation probability only only has 17% precipitation probability.Generally, the approximate linear relationship that presents of precipitation probability and air pressure fluctuation amplitude.In normal error range, this algorithm is quite reliable, but the difference due to the topography and geomorphology of different regions, the difference of climate zone of living in, add the interference of human factor, such as the rainmaking in some areas, city, between the suburb, field of the city tour sight spot that the density of population is large and spaciousness, certain difference is also arranged, it is not very remarkable causing this algorithm effect that only relies on air pressure fluctuation to predict precipitation probability, and precision is not high enough.When the mean sea level in a certain area is relatively very high, for example at mean sea level more than 3000 meters, this algorithm just lost efficacy possibly.Because mountain area is as the special area of a weather, in most of the cases, atmospheric pressure is no longer the main criterion of its Changes in weather.In addition, in the Northwest inland arid area, such as the Takla Makan Desert in Xinjiang, loess plateau etc., pressure liftable is also also not obvious on the impact of weather conditions, so we need to be optimized algorithm.Another is at the example of arid area, and than European northern territory ， Spain, atmospheric decline can not cause the appearance of cloud layer so easily, and brings out rainfall.
the part that weather is paid close attention to the most as people's daily life, all inseparable with all activities in production of people.Develop rapidly day by day along with modern science and technology, " a storm may arise from a clear sky " this concept is fallen by desalination already, estimation range, precision and the range of weather forecast in the present age are also in continuous lifting, greatly for people's productive life and trip brought convenient, simultaneously, we are also improving year by year for the demand of personalized weather forecasting service.
yet existing equipment is difficult to satisfy the demands.Mostly be based on single Pressure monitoring at existing individual meteorological predictor and carry out weather forecasting, expensive or can only unit use forecast, precision is limited.
at present, domestic individual Meteorological service market product rareness, insufficiency and cost are high, there is no the ripe product of the weather prognosis for the personal user, in the face of these market vacancys, are badly in need of a kind of product, make up the market vacancy.Simultaneously, " concept of cloud computing and " Internet of Things " just progressively enters our life, allows weather station better utilize modern science and technology to become current urgent problem.
