specifically, the triggering conditions of the early warning model comprise single-parameter early warning criteria, multi-parameter early warning criteria combination and macroscopic phenomenon and microscopic data combined early warning criteria. The early warning is carried out by utilizing early warning criterion parameters of single equipment, namely, when real-time monitoring data such as water content, cracks, earth surface displacement, inclination angle, mud level and the like uploaded by monitoring equipment are subjected to data preprocessing, a criterion expression reaching the early warning level of one sensing equipment in the model is triggered, and the gateway can immediately issue an early warning message.

Specifically, the standard score algorithm is a standard score obtained by converting a certain original score, and the standard score can make the values which are not compared originally become comparable. Further, the disaster monitoring data are subjected to standardized processing by adopting a standard score algorithm, and scaled to be within a preset range. The preset range is a range in which data processing can be performed. The algorithm formula is as follows:
where μ is the mean of the set of data, σ is the standard deviation of the set of data, and Z is the standard score. For example, the rainfall collection value for a certain period in the area is 22, the average rainfall in the area is 14, the standard error is 2, and at this time, the Z-score in this example is:
the sampling result of this time is lower than the average value by 4 standard deviations. The algorithm can detect abnormal data in the data such as rainfall, water content and the like, and mark elimination is carried out.
Further, the principal component analysis algorithm retains as much information as possible by reducing the number of data indexes to perform dimension reduction of high-dimensional data and extract principal characteristic components of the data.

And (3) carrying out centering and normalization on all the features, calculating a covariance matrix of the sample, solving the feature values and the feature vectors for the covariance matrix, and selecting the feature vectors corresponding to the K largest feature values as main components. For example, if data of debris flow in himalayan mountain is obtained, the data of debris flow is obtained by the topography condition, the loose material source condition, and the water source condition.
Further, the rada criterion is to assume that a group of detection data only contains random errors, calculate it to obtain standard deviation, determine a section according to a certain probability, consider that the errors exceeding the section are not random errors but coarse errors, and reject the data containing the errors. Further, the disaster monitoring data are checked by adopting the Laida rule, and abnormal data are marked and removed. Calculating the average value and standard deviation, the upper limit and the lower limit of the data, wherein the upper limit is equal to the average value plus 3 times of the standard deviation, the lower limit is equal to the average value minus 3 times of the standard deviation, comparing the relation between the data point and the upper limit and the lower limit, and judging the data point as abnormal data and marking and removing if the data point is larger than the upper limit or smaller than the lower limit. For example, in meteorological data, if the temperature in the data is in the range of 20-30 ℃, if the temperature of the random error is 40 ℃, marking and rejecting are carried out.
Further, the disaster monitoring data are subjected to standardized processing by adopting a standard score algorithm and subjected to dimension reduction processing by adopting a principal component analysis algorithm, and then the disaster monitoring data are inspected by adopting a Laida criterion. Accordingly, disaster monitoring data are standardized by adopting a standard score algorithm, and then the disaster monitoring data are checked by adopting a Leida criterion. Or performing dimension reduction processing on the disaster monitoring data by adopting a principal component analysis algorithm, and then checking the disaster monitoring data by adopting a Laida criterion.

For example, if the monitored disaster type is weather data, the calculated values may include temperature monitoring values and the like.
Further, setting alarm level parameters of each criterion to the calculated value to obtain an early warning threshold. The criterion is a decision criterion. For example, the alarm level parameter is set for the temperature monitoring value of the calculated value according to the criterion, and the early warning threshold is 40 ℃ when the temperature monitoring value is below 40 ℃.
Further, according to the monitoring data of the sensor, the calculated value and the early warning level threshold value form a trigger condition, and whether the calculated value meets the early warning level threshold value is judged. The calculated value and the early warning threshold value can be combined into a trigger condition according to the data of various types of sensors, and the early warning criterion expression of the sensors is formed through mathematical operations such as numerical comparison, OR, AND and the like.
