Step 103, the water quality parameter of boiler water is detected.For example, control assembly 3 is by the testing result of boiler water quality and in advance
The acceptability limit of the boiler water quality of storage compares.
Step 104, the water quality condition and/or water quality condition variation tendency of boiler water are determined according to water quality parameter, and according to
Water quality condition and/or water quality condition variation tendency are selectively alarmed.
For example, control assembly 3 judges that the testing result of the boiler water quality of therrmodynamic system 1 is located at pre-stored boiler water quality
Acceptability limit in when, control assembly 3 judges that the water quality of therrmodynamic system 1 is qualified, and control assembly 3 is not alarmed at this time.Control assembly 3
When judging that the testing result of the boiler water quality of therrmodynamic system 1 is located at outside the acceptability limit of pre-stored boiler water quality, control group
Part 3 judges that the water quality of therrmodynamic system 1 is unqualified, and control assembly 3 sends alarm signal alarm at this time, promotes personnel manually or heating power
1 automatic pollution discharge of system.
Automatic sampling and automatic remittance to boiler water may be implemented in the water quality detection method of therrmodynamic system according to the present invention
Total water quality detection information, has saved manpower, ensure that detection precision.
Specifically, as shown in Fig. 2, water quality detection method further includes step 105, water quality condition and/or water quality condition are become
Change trend reports to server.Such as the result of the boiler water quality measured can be uploaded to server for personnel by control assembly
Analysis.
Specifically, first switch signal is received in step 101, comprising: receive and come user terminal and/or the hair of server 32
The first switch signal sent, wherein first switch signal includes switching frequency.For example, control assembly 3 is received by communication module 31
After the first switch signal sent to server 32, first is periodically turned on and closed according to the switching frequency of first switch signal certainly
Movable valve 21.
Specifically, water quality detection method further include:

Water.For example, control assembly 3, which controls the second automatic valve 61, opens the second sampling line 6,4 softened water of softening water tank passes through second
Sampling line 6 flows to softened water quality detector 64.
Detect the water quality parameter of softened water.For example, control assembly 3 by the testing result of softened water quality with it is pre-stored
The acceptability limit of softened water quality compares.
When softened water quality detection information is located in softened water quality acceptability limit, such as the judgement detection of control assembly 3
The hardness number result softened water that is located at softening water tank 4 qualified hardness number within the scope of when, control assembly 3 judges softening water tank 4
Water quality it is qualified.
When softened water quality detection information is located at outside softened water quality acceptability limit, i.e., at least one softened water quality is examined
When measurement information is located at outside respective acceptability limit, such as control assembly 3 judges the hardness number result of the softened water of detection positioned at soft
When changing within the scope of the qualified hardness number of the softened water of water tank 4, control assembly 3 judges that the water quality of softening water tank 4 is unqualified, at this time people
Member or control device can take the measures such as blowdown to softening water tank 4 in time according to unqualified result, and dirty water is avoided to flow into heat
Force system 1 guarantees the normal operation of therrmodynamic system 1.
Thus, it is possible to realize to the automatic sampling of softened water and summarize water quality detection information automatically, manpower is saved, guarantee
Detection precision.
