8. The method for monitoring and alarming the pressure of the fuel gas in the pipeline according to claim 7, further comprising:
Acquiring the next second map position to which the gas maintainer is going, and taking the next second map position as a target map position;
acquiring auxiliary solution suggestions of the pressure anomalies corresponding to the target map positions;
mapping the auxiliary resolution suggestion into the visual alert model;
wherein, acquire the gas maintainer is about to go to next the second map position includes:
Receiving the next map position to be sent, which is input by the gas maintenance personnel;
Or alternatively, the first and second heat exchangers may be,
When the gas maintainer only views two second map positions, the gas maintainer reaches one second map position which is only visible in a history manner, and the first duration of the first visibility is larger than or equal to a preset first duration threshold value, the second map position which is only visible in the gas maintainer and is not reached in the history manner is taken as the next second map position which is going to be seen;
Or alternatively, the first and second heat exchangers may be,
When the gas maintainer only views one second map position and the second only viewing duration is longer than or equal to a preset second duration threshold, taking the second map position which is only viewable by the gas maintainer as the next second map position to be moved;
Or alternatively, the first and second heat exchangers may be,
Taking the second map position closest to a target end point as the next second map position to which the gas maintainer is going; the target end point is an end point of a visual road which is continuously closest to the model center of the visual alarm model in a target time interval; the target time interval is an operation time interval in which the gas maintainer sequentially performs operations of amplifying a picture, dragging the picture and reducing the picture in the visual alarm model.
9. The method for monitoring and alarming the pressure of the fuel gas in the pipeline according to claim 6, further comprising:
and updating the site map at fixed time.
10. The method for monitoring and alarming the pressure of the fuel gas in the pipeline according to claim 6, further comprising:
And pushing the visual model alarm to a background person.
