Pattern.Course of work during both patterns is taken to be illustrated respectively the Warm status supervising device 6 below：
The first situation (active sending mode)：The Warm status supervising device 6 includes active transmitting element, in the heat
When state parameter changes, for example, the valve of registering one's residence that heat user is closed on heat supply branch pipe(tube) 63, the Warm status supervising device
6 actives will close valve information transmission to the dynamic equilibrium control device 5, so as to make the dynamic equilibrium control device
5 timely send Regulate signal (signal for reducing the heating load on the heat supply main pipeline 61) to the district grid device 4,
The district grid device 4 reduces the frequency of the water circulating pump 3, so that flowing to the heat of other users can't be reduced.
The active transmitting element actively sends real-time Warm status parameter to the dynamic equilibrium control device 5.In the confession of the regulation
When the user of hot subregion is two (being respectively the first heat user and the second heat user), wherein the first heat user heat supply branch pipe(tube) 63
On valve close after, the frequency of the water circulating pump 3 is reduced, and the heating agent in the heat supply main pipeline 61 is also reduced, after reduction
The heat supply main pipeline 61 in heating agent flow in the second heat user, the indoor temperature of second heat user can't be sent out
It is raw to change.When the user of the heat supply subregion of the regulation is three, heating agent mean allocation in the heat supply main pipeline 61 is to another
Outer two are not turned off in the heat user of valve.Because the heat in the heat supply main pipeline 61 after regulation is reduced with demand and is dropped

Plus after the heat supply main pipeline 61 in heating agent mean allocation into first heat user and second heat user.It is described
The indoor temperature of first heat user is brought rapidly up, and the indoor temperature of second heat user will not also be reduced.
Second of situation (passive sending mode)：The Warm status supervising device 6 includes passive transmitting element, when dynamically flat
When weighing apparatus control device 5 carries out periodically gathering each family Warm status parameter, the Warm status parameter after change is sent to dynamic equilibrium
Control device 5.The dynamic equilibrium control device 5 gathers the Warm status by its acquisition module in preset time period and monitored
The Warm status parameter of device 6, the preset time period can for 5 minutes, 10 minutes, 20 minutes, 30 minutes, 1 hour etc. it is any
Time interval.After the Warm status parameter of collection changes, the dynamic equilibrium control device 5 is to the district grid device
4 send Regulate signal, and the district grid device 4 adjusts the frequency of the water circulating pump 3 according to the Regulate signal.
Further, when using passive sending mode, active sending mode can also be used simultaneously.Can be with by user
Actively Warm status parameter is sent to the dynamic equilibrium control device 5, or after preset time period it is passive by described dynamic
State balance control device 5 is acquired.
Adjust control principle：Each family of the regular visit of dynamic equilibrium control device 5 with Warm status or the Warm status at each family
The status information of change is transferred to dynamic equilibrium control device 5 by supervising device 6 in resident family when having change with Warm status；Dynamic

Can be compensated during the flow that area needs according to occupancy rate), it would be desirable to flow and actual flow are contrasted, and calculate regulated quantity
(can be absolute magnitude and relative percentage regulated quantity)；Regulated quantity is transferred to district grid device 4 by dynamic equilibrium control device 5,
The flow of 4 pairs of each subregions of district grid device is adjusted.Primary regulation is possible to not in place, thus also to carry out once or
Repeatedly correction.
Below with a kind of by the way that the regulation of water circulating pump is further described by way of realizing dynamic energy-saving effect：
The frequency of the water circulating pump 3 is 0~50 hertz,
Setting range is 4000~20000, wherein 0 hertz of the correspondence of setting value 4000,50 hertz of the correspondence of setting value 20000,
Other medians are calculated using interpolation method correspondence.
If setting flow as m, actual flow is n, and set of frequency is x, and actual frequency values are p, and regulation step pitch is that (β is ＜ to β
1 numerical value)
So adjusting ratio is
So
Then
Wherein, the actual frequency values set and calculated in the state energy-saving control device is moved, the district grid dress
Frequency values can be corresponded to by setting value automatically by putting.The corresponding frequency of minimum value is 0 in setting range, and this minimum value is regulation dress
Put internal determination.Such as general device is 0-10 volts as signal using voltage, and setting value is 0-10000；Done using electric current
It it is 4-20 milliamperes for signal, setting value is 4000-20000.This certain value can be adjusted according to the difference of equipment.
