Wherein environment coefficient can be temperature dependent, and such as during season, difference variation is larger, can be tied to prediction Fruit has an impact, therefore can compare forecast pressure value with the actual pressure value at corresponding time point, determines environment coefficient. Specifically, it is determined that in the process, multigroup forecast pressure value and actual pressure value can be acquired, determine learning model, using the model Environment coefficient is adjusted, and then determines the environment coefficient.

Step S303 is corrected the correspondence of pressure and time using environment coefficient.

Step S304 carries out the indoor pressure value of SF6 gas pre- according to the correspondence of pressure and time after correction It surveys.

Specifically, above-mentioned correction course can be carried out in forecast pressure value and larger actual pressure value gap.It such as can be with The forecast pressure value and actual pressure value are compared at regular intervals, if difference is more than predetermined threshold value, carry out school Just.

In a possible embodiment, after above-mentioned steps S203, further include:It is carried out according to the indoor pressure value of SF6 gas Forecast pressure value after prediction and preset alarm threshold value, prediction and alarm time;Obtain the corresponding Weather information of time of fire alarming, the same day When humidity value in gas information is more than humidity threshold, sends tonifying Qi in advance and prompt terminal corresponding to staff.

Specifically, as being June 23 when predicting time of fire alarming, and corresponding Weather information on June 23 is that humidity is 80%, be more than humidity threshold 70% at this time, then the prompt of transmission tonifying Qi in advance to the corresponding terminal of staff.
