The compute classes of decreasing with the flow network of hot water secondary water seemingly, the heat net of hot water secondary water decreases and also need not the judgement that the incident that compensates takes place and the calculating of offset;
The presupposition analysis cycle can be hour, day, month; Therefore; The total hot water primary water presupposition analysis cycle flow network of corresponding the whole network decreases and is respectively the total hot water primary water of the whole network hour flow network damage, the total moon in water flow network of hot water that the hot water primary water that hot water primary water daily flow net decreases, the whole network is total week flow network decreases, the whole network is total of the whole network decreases; The corresponding hot water primary water hour flow network damage of branch road, the hot water primary water daily flow net damage of branch road, the hot water primary water week flow network damage of branch road, the moon in water flow network of hot water of branch road of having comprised of the hot water primary water presupposition analysis cycle flow network damage of branch road decreases; Hot water secondary water presupposition analysis cycle flow network decreases correspondence and has comprised that hot water secondary water daily flow net damage, all flow networks of hot water secondary water decrease, hot water secondary moon in water flow network decreases, and hot water secondary water presupposition analysis cycle heat net decreases correspondence and comprised that hot water secondary water day heat net damage, all heat nets of hot water secondary water decrease, hot water secondary moon in water heat net decreases;
With heating agent be that the situation of steam is similar; Because the personnel of heating enterprise outfit at night are less; Thereby a lot of problems can be accumulated to the working time of next day and solve, therefore when carrying out the calculating that day net decreases can with the acquisition time point by 0 o'clock of start time point every day in each presupposition analysis cycle change into the morning 9 between 11 o'clock;
Heating agent be hot water analytic process and step 4, five and heating agent be the basic identical of steam, repeat no more at this;
Step 6, control module 4 receptions are controlled through regulating 402 pairs of field apparatus of temperature control adjusting valve based on preset program after transmitting next heat supply information and control information by transport module 2:
The outdoor temperature that the experience that combines heat exchange station technological requirement and heat exchange station daily management is made and the relation curve of heat supply are stored in the control module 4, thereby adjust heat supply by the aperture of the control module 4 outdoor temperature auto-control temperature control adjusting valve 402 that unification in real time issues according to the heating enterprise that receives then; Simultaneously; For same outdoor temperature; Cloudy day and blow the weather of northwester and the weather of sunny sun Gao Zhao; Human feeling's difference, heating enterprise just can be revised outdoor temperature through heat supply monitoring system of the present invention neatly, carry out temperature compensation or directly issue complement operation information transferring to control module 4 by transport module 2 and regulating.
The calculating that be to cooperate net to decrease, measuring instrument is in year calibrating, maintenance or when changing, and the integrated flux of former table inserted be equipped with in the table, when recovering former measuring instrument, new cumulative flow value inserted, and so just can reduce the workload of the judgement and the calculating of compensation incident.
More than two kinds of embodiments be two kinds of situation that heating agent is respectively steam and hot water; If occur in the heat supply; As: need transfer steam to situation that hot water carries out heat supply; Then only need in steam pipe system, to add the steam-water heat exchanging station, this moment the branch road at this place, steam-water heat exchanging station is carried out computational analysis as a user and get final product, or the combination heating agent is that two kinds of situation of steam and hot water are carried out computational analysis.
