202nd, respectively detect whether point sensor there are corresponding current detection data according to the current detection data search；If
Checking the first detection point sensor does not have current detection data, then performs step 208；If check the first detection point sensor
There are current detection data, then perform step 203.
Wherein, if checking the first detection point sensor does not have current detection data, illustrate that the first detection point sensor can
Can it not start, it is also possible to start but because failure can not obtain the data of the test point, it is also possible to be other phases
The reason for pass.However, how, during sensor fault diagnosis, from the point of view of client, as long as not receiving the first inspection
The current detection data of measuring point sensor, the possibility for being presented to client are exactly the first detection point sensor and executive component event
Barrier.
Specifically for example, in air-conditioning system as shown in Figure 3, using model described in table 1, according to the configuration file of table 2 and the institute of table 3
The data file stated carries out fault diagnosis.Since certain moment, return fan detection point sensor T1 measured value is always without detection
Data, accordingly, judge that return fan detection point sensor T1 and executive component break down.
Special instruction, when checking the first detection point sensor and there are current detection data, step 203 can be performed, is entered
And use 203 determination methods judge corresponding detection point sensor whether failure, step 203 can not also be performed, and direct
Perform step 204 the step of arrive step 207, judge to detect accordingly point sensor whether failure.This can also directly be terminated
Fault diagnosis.When checking the first detection point sensor and there are current detection data, step 203 is directly performed, because it is pin
To the fault diagnosis of single test point, whether failure is more convenient diagnosis detection point sensor to a certain extent.But it is directed to
This, the specific embodiment of the invention is not limited to this.User can carry out different selections according to real needs, and then carry out
Different settings.
Further, when the attribute change be characterized as detect data change, according to the attribute change feature to described
Current detection data are analyzed, judge each detection point sensor and executive component whether the method for failure, can use but not
It is confined to step 203：
203rd, detection data of the first detection point sensor within a period of time are according to the data analysis stored
It is no change to be present；If not changing, step 208 is performed；If changing, step 204 is performed.
Wherein, if according to the data analysis stored, determine the first detection point sensor within a predetermined period of time
Detection data do not change, and illustrate that the first detection point sensor is likely to be at deadlock state, before the data transmitted up are
The data of collection, and non-current；It could also be possible that other problemses, however, how, in the process of sensor fault diagnosis
In, from the point of view of client, as long as the current detection data for receiving the first detection point sensor do not become within a predetermined period of time
Change, be presented to client is probably the first detection point sensor and executive component failure, and the predetermined amount of time can be according to reality
Border needs to be set.
Special instruction, when checking the first detection point sensor current detection data and changing, step can be performed
204, and then directly perform step 204 the step of arrive step 207, judge to detect accordingly point sensor whether failure.Can also
Directly terminate this fault diagnosis.The specific embodiment of the invention is not limited to this.User can be carried out according to real needs
Different selections, and then carry out different settings.

Point sensor and executive component whether failure when, this method includes：
204th, the current logic relation according to each detection point sensor testing number of current detection data generation between.
In Fig. 3, the detected value that point sensor T5 is detected after cooling coil is more than the detection of detection point sensor T6 after hot coil
It is worth, the detected value that point sensor T6 is detected after hot coil is less than the detected value of test point T7 after heater, i.e. T5>T6<T7.
205th, the current logic relation is matched with corresponding physical logic relation；If mismatching, step is performed
Rapid 206；If matching, perform step 207.
Wherein, before the present embodiment is performed, the embodiment of the present invention also includes setting detection point sensor testing number according to it
Between logical relation, the logical relation include in multiple test points physical logic relation, the embodiment of the present invention is provided with T5,
Inherent physical logic relation between T6, T7,3 test points, the inherent physical logic relation are:T5≤T6≤T7.According to
The content that the step 204 of the embodiment of the present invention is illustrated is analyzed, and draws current T5, the logical relation T5 between T6, T7>T6<
T7, mismatched with the inherent physical logic relation T5≤T6≤T7 obtained from the configuration file pre-seted, it is determined that this three
Test point T5, T6, T7 sensor and corresponding executive component failure, but be specifically this which of three or which failure, go back
It is corresponding executive component failure, it is necessary to related staff, according to the diagnosis, does further malfunction elimination, could most
Confirm eventually, specific malfunction elimination mode, the embodiment of the present invention is not limited to this.
As the continuity of the step, further can be broken down simultaneously according to each detection multiple sensors of point sensor general
The smaller result for being used as basis for estimation, can directly exporting T5 test point sensor faults of rate.
Many kinds can be set according to the decision logic that configuration file generates.Again for example：When the data of numbering 1（Working mould
Formula）It is worth for 1（Characterize winter mode）When, the current testing number obtained from certain moment is according to the data for being numbering 7（Water valve aperture）
More than 0.05, and number the data for being 5（Mixed air temperature）The data for being 6 more than numbering（Wind pushing temperature）, and difference is more than 0.5 DEG C
When, judge numbering be 1,5,6,7 data at least one error.
206th, judge that current logic relation accordingly detects point sensor and executive component failure.
207th, judge that current logic relation accordingly detects point sensor and executive component non-faulting.
208th, the first detection point sensor and executive component failure are judged.
Further, after sensor and executive component failure is judged, in order to facilitate guardian or user can and
When be to know, the present invention implement it is determined that after sensor and executive component failure, send alarm；Specifically include：Filled to alarm
Transmission warning message is put, so that the warning device is alarmed according to the warning message.Wherein, the mode present invention of the alarm is real
Apply example to be not limited this, can be sound, can be light, can be presentation of information and its combination, or other can
In a manner of alarm.
