Algorithmical support of the monitoring system database has a double load. On
the one hand, the accumulation of data about the functioning of the ecological
system of the gas
field zone allows us to increase the reliability of receiving
assessments of the ecological situations and to decrease the demands to the mea-
suring subsystem. On the other hand, the monitoring system database can be used
as a fragment of the regional or national database.
The monitoring system functioning is secured by the correlation between the
measuring subsystem, the regenerated database and the model. According to Aota
et al. (1993), continuous monitoring can be realized with suf
cient stability only
under adaptive algorithmical support. The dynamic correlation of the functioning
regimes for all subsystems is represented schematically in Fig.
4.28
. According to
this scheme, the measuring subsystem can work in discrete regimes together with
the model. Detectors of emergency situations work only in the continuous regime.
