Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
The embodiment of the invention discloses a kind of temperature-sensitive bag fault detection method and system, to solve to cause because of low temperature environment
Temperature-sensitive bag fault misdescription problem, and when temperature-sensitive bag failure really occurs in temperature-sensitive bag, normally report failure.
Referring to Fig. 1, a kind of temperature-sensitive bag fault detection method flow chart disclosed in one embodiment of the invention, this method includes step
Suddenly：
Step S101, when air-conditioner set is shut down, judge be located at the air-conditioner set on temperature-sensitive bag to be detected whether go out
Existing temperature-sensitive bag failure, if it is, performing step S102；
Air-conditioner set described in this step, which is shut down, to be included：Shutdown and air-conditioner set operation one before air-conditioner set operation
Shutdown after the section time.
Temperature-sensitive bag failure includes：Temperature-sensitive unwraps road and the short circuit of temperature-sensitive bag.
In actual applications, the temperature-sensitive bag of negative temperature coefficient because the resistance value in low temperature environment it is very big, close to temperature-sensitive
Road is unwrapped, therefore, the situation of temperature-sensitive bag " unwrapping road close to temperature-sensitive " is easily mistakenly considered temperature-sensitive bag and opened a way by air-conditioner set
Failure；Similarly, the temperature-sensitive bag of positive temperature coefficient because the resistance value in low temperature environment it is very small, close to temperature-sensitive bag short circuit, therefore,
The situation of temperature-sensitive bag " close to the short circuit of temperature-sensitive bag " is easily mistakenly considered temperature-sensitive bag and occurs short trouble by air-conditioner set.
Therefore, when air-conditioner set is shut down, if there is temperature-sensitive in the temperature-sensitive bag to be detected detected on the air-conditioner set
Bag failure, and can not determine that the temperature-sensitive bag failure is due to caused by low temperature environment or the temperature-sensitive bag to be detected is really felt
Thermometer bulb failure.
It should be noted that when air-conditioner set is shut down, if it is determined that temperature-sensitive bag to be detected does not occur temperature-sensitive bag failure, then table
Bright temperature-sensitive bag to be detected is normal temperature-sensitive bag, and now, air-conditioner set can be run after start-up command is received with normal boot-strap.
Step S102, continuation judge in the air-conditioner set with other temperature-sensitive bags of temperature-sensitive bag same type to be detected whether
Occurs the temperature-sensitive bag failure, if it is not, then step S103 is performed, conversely, performing step S104；
Same type in this step is referred to：With temperature-sensitive bag to be detected be located at same air-conditioner set other temperature-sensitive bags and
Temperature-sensitive bag to be detected is the temperature-sensitive bag of positive temperature coefficient, or is the temperature-sensitive bag of negative temperature coefficient, in other words, other senses
The variation tendency of the resistance value of thermometer bulb and temperature-sensitive bag to be detected under identical environment temperature is identical.
Step S103, output prompt message, the prompt message are used to point out the temperature-sensitive bag to be detected the sense occur
Thermometer bulb failure；
Step S104, judge that the temperature-sensitive bag failure causes as low temperature environment, shield the temperature-sensitive bag failure, stop to institute
State temperature-sensitive bag to be detected and carry out fault detect.
In the present embodiment, by judging whether to be located at other temperature-sensitive bags of same air-conditioner set with treating with temperature-sensitive bag to be detected
Detect that identical temperature-sensitive bag failure occurs for temperature-sensitive bag, to determine that the temperature-sensitive bag failure is due to caused by low temperature environment or this is treated
Really there is temperature-sensitive bag failure in detection temperature-sensitive bag.
Specifically resolution principle is：When being located at temperature-sensitive bag to be detected in other temperature-sensitive bags of same air-conditioner set, there is any
One or multiple temperature-sensitive bags are normal namely during without occurring temperature-sensitive bag failure, show the environment that temperature-sensitive bag to be detected is presently in
Temperature is not low, and the temperature-sensitive bag failure that temperature-sensitive bag to be detected occurs is due to caused by temperature-sensitive bag itself to be detected, namely to be detected
Temperature-sensitive bag really occurs in that temperature-sensitive bag failure, in this case, exports for pointing out temperature-sensitive bag to be detected the event of temperature-sensitive bag occur
The prompt message of barrier, normally reports failure.
When being located at temperature-sensitive bag to be detected in other temperature-sensitive bags of same air-conditioner set, occur and temperature-sensitive bag phase to be detected
With temperature-sensitive bag failure when, then judge that the temperature-sensitive bag failure that temperature-sensitive bag to be detected occurs is probably caused by low temperature environment, at this
In the case of kind, the temperature-sensitive bag failure of temperature-sensitive bag to be detected is shielded, stops carrying out fault detect to temperature-sensitive bag to be detected.
In summary, the invention discloses a kind of temperature-sensitive bag fault detection method, when air-conditioner set is shut down, if to be detected
There is temperature-sensitive bag failure in temperature-sensitive bag, then continues to judge other temperature-sensitive bags in air-conditioner set with the temperature-sensitive bag same type to be detected
Whether occur the temperature-sensitive bag failure, if the temperature-sensitive bag failure occurs for other temperature-sensitive bags, judge temperature-sensitive bag to be detected
Temperature-sensitive bag failure caused by low temperature environment, now, to shield temperature-sensitive bag failure, stop carrying out failure inspection to temperature-sensitive bag to be detected
Survey, if there is the temperature-sensitive bag that temperature-sensitive bag failure does not occur in other temperature-sensitive bags, judge temperature-sensitive bag failure not low temperature environment
It is caused, now, export the prompt message of temperature-sensitive bag failure.The present invention is located at same unit by judging with temperature-sensitive bag to be detected
Same type other temperature-sensitive bags, if occur with temperature-sensitive bag identical temperature-sensitive bag failure to be detected, to determine sense to be detected
Whether thermometer bulb really there is temperature-sensitive bag failure, and output prompting letter when it is determined that temperature-sensitive bag failure really occurs in temperature-sensitive bag to be detected
Breath.Therefore, the present invention is not only solved because of temperature-sensitive bag fault misdescription problem caused by low temperature environment, but also can be to be checked
Survey temperature-sensitive bag really to occur exporting prompt message during temperature-sensitive bag failure, air-conditioner set is normally reported failure, so as to ensure air conditioner
The normal operation of group.
It is appreciated that after determining that temperature-sensitive bag failure really occurs for temperature-sensitive bag to be detected, to ensure the normal of air-conditioner set
Operation, it is necessary to temperature-sensitive bag to be detected is changed or repaired, is changed or the maintenance period in temperature-sensitive bag to be detected,
Air-conditioner set will be unable to normal work.
Therefore, after above-described embodiment step S103, step can also be included：
When receiving start-up command, forbid air-conditioner set start operation.
When it is determined that the temperature-sensitive bag failure that temperature-sensitive bag to be detected occurs is due to caused by low temperature environment, then, show that this is treated
Detect that temperature-sensitive bag is really normal, then air-conditioner set can normally be run.
Therefore, after above-described embodiment step S104, in addition to step：
Allow air-conditioner set after start-up command is received, start operation.
It is appreciated that after air-conditioner set runs a period of time, the temperature at some positions of air-conditioner set, such as gas exhaust piping
Temperature will be raised, then correspondingly, and the resistance value positioned at the temperature-sensitive bag at these positions can be with air-conditioner set run time
Lengthen and change, such as, be vented temperature-sensitive bag, after air-conditioner set runs a period of time, the temperature rise of blast pipe causes
Positioned at the resistance value increase of the exhaust temperature-sensitive bag of blast pipe.Therefore, for that can be changed in air-conditioner set running
Temperature-sensitive bag, can after air-conditioner set runs a period of time, by judging whether the own temperature of the temperature-sensitive bag changes,
To determine whether the temperature-sensitive bag occurs temperature-sensitive bag failure.
Therefore, it is further optimization above-described embodiment, referring to Fig. 2, a kind of temperature-sensitive bag disclosed in another embodiment of the present invention
Fault detection method flow chart, on the basis of embodiment illustrated in fig. 1, after step s 104, in addition to step：
Step S105, after air-conditioner set runs preset time, judge temperature-sensitive bag to be detected whether still with the temperature-sensitive
Bag failure, if it is, performing step S106；
Wherein, the preset time in this step needs long enough, to ensure that air-conditioner set is run after the preset time, some senses
The temperature of thermometer bulb collection is bound to change, and the concrete numerical value of the preset time is according to depending on being actually needed, and the present invention is herein
Do not limit.
Step S106, judge whether the temperature-sensitive bag to be detected is, in normal work, to be run in the air-conditioner set
The temperature-sensitive bag that own temperature changes in journey, if it is, performing step S107, otherwise performs step S108；
Step S107, output prompt message, and control the air-conditioner set out of service；
Wherein, the prompt message is used to point out temperature-sensitive bag to be detected temperature-sensitive bag failure occur.
When judging temperature-sensitive bag to be detected as in normal work, own temperature changes in air-conditioner set running
Temperature-sensitive bag when, air-conditioner set operation preset time after, if the temperature-sensitive bag failure of temperature-sensitive bag to be detected is due to low temperature environment
Caused, then the temperature that the temperature-sensitive bag to be detected is gathered can change, so that temperature-sensitive bag to be detected is no longer complies with sense
The condition of thermometer bulb failure, the condition includes：Temperature-sensitive unwraps road and the short circuit of temperature-sensitive bag；If the temperature-sensitive bag failure of temperature-sensitive bag to be detected is
Temperature-sensitive bag faults itself to be detected causes, then the temperature-sensitive bag to be detected still conforms to temperature-sensitive bag fault condition, and now, exporting is used for
Temperature-sensitive bag to be detected is pointed out the prompt message of temperature-sensitive bag failure occur.
Step S108, continuation shield the temperature-sensitive bag failure, stop carrying out fault detect to the temperature-sensitive bag to be detected, and
The air-conditioner set is controlled to continue to run with.
When judging temperature-sensitive bag to be detected as in normal work, own temperature does not become in air-conditioner set running
During the temperature-sensitive bag, such as external environment temperature-sensitive bag of change, it is believed that the temperature-sensitive bag failure of temperature-sensitive bag to be detected is still due to that low temperature environment causes
, in this case, continue to shield temperature-sensitive bag failure, stop carrying out fault detect to the temperature-sensitive bag to be detected, and control
Air-conditioner set is continued to run with.
In summary, after air-conditioner set runs preset time, if temperature-sensitive bag to be detected still has temperature-sensitive bag failure, lead to
Cross and judge whether the temperature-sensitive bag to be detected is that, in normal work, own temperature changes in air-conditioner set running
Temperature-sensitive bag, to determine that temperature-sensitive bag failure be due to that low temperature environment causes also is due to that temperature-sensitive bag faults itself to be detected causes, and
When it is determined that temperature-sensitive bag failure causes for temperature-sensitive bag faults itself to be detected, the prompt message of temperature-sensitive bag failure is exported.Therefore, originally
Invention is not only solved because of temperature-sensitive bag fault misdescription problem caused by low temperature environment, but also can be in temperature-sensitive Bao Zhen to be detected
Just occurring exporting prompt message during temperature-sensitive bag failure, air-conditioner set is normally reported failure, so as to ensure the normal fortune of air-conditioner set
OK.
In the present embodiment, when step S105 judges that temperature-sensitive bag to be detected does not have temperature-sensitive bag failure, air-conditioner set is controlled
Continue to run with.
It is appreciated that before step S105, air-conditioner set should be controlled to run first, therefore, before step S105
Also include：
When receiving start-up command, control air-conditioner set start operation.
Corresponding with above method embodiment, the invention also discloses a kind of temperature-sensitive bag fault detection system.
Referring to Fig. 3, a kind of structural representation of temperature-sensitive bag fault detection system, the system disclosed in one embodiment of the invention
Including：
First judging unit 201, for when air-conditioner set is shut down, judging the sense to be detected being located on the air-conditioner set
Whether thermometer bulb there is temperature-sensitive bag failure, and the temperature-sensitive bag failure includes：Temperature-sensitive unwraps road and the short circuit of temperature-sensitive bag；
Air-conditioner set, which is shut down, to be included：Shutdown and air-conditioner set before air-conditioner set operation run stopping after a period of time
Machine.
In actual applications, the temperature-sensitive bag of negative temperature coefficient because the resistance value in low temperature environment it is very big, close to temperature-sensitive
Road is unwrapped, therefore, the situation of temperature-sensitive bag " unwrapping road close to temperature-sensitive " is easily mistakenly considered temperature-sensitive bag and opened a way by air-conditioner set
Failure；Similarly, the temperature-sensitive bag of positive temperature coefficient because the resistance value in low temperature environment it is very small, close to temperature-sensitive bag short circuit, therefore,
The situation of temperature-sensitive bag " close to the short circuit of temperature-sensitive bag " is easily mistakenly considered temperature-sensitive bag and occurs short trouble by air-conditioner set.
Therefore, when air-conditioner set is shut down, if there is temperature-sensitive in the temperature-sensitive bag to be detected detected on the air-conditioner set
Bag failure, and can not determine that the temperature-sensitive bag failure is due to caused by low temperature environment or the temperature-sensitive bag to be detected is really felt
Thermometer bulb failure.
It should be noted that when air-conditioner set is shut down, if it is determined that temperature-sensitive bag to be detected does not occur temperature-sensitive bag failure, then table

First output unit 203, in the case of being judged as NO in second judging unit 202, output prompting letter
Breath, the prompt message is used to point out the temperature-sensitive bag to be detected the temperature-sensitive bag failure occur；
First screen unit 204, in the case of being judged as YES in second judging unit 202, judges the sense
Thermometer bulb failure causes for low temperature environment, shields the temperature-sensitive bag failure, stops carrying out fault detect to the temperature-sensitive bag to be detected.
In the present embodiment, by judging whether to be located at other temperature-sensitive bags of same air-conditioner set with treating with temperature-sensitive bag to be detected
Detect that identical temperature-sensitive bag failure occurs for temperature-sensitive bag, to determine that the temperature-sensitive bag failure is due to caused by low temperature environment or this is treated
Really there is temperature-sensitive bag failure in detection temperature-sensitive bag.
Specifically resolution principle is：When being located at temperature-sensitive bag to be detected in other temperature-sensitive bags of same air-conditioner set, there is any
One or multiple temperature-sensitive bags are normal namely during without occurring temperature-sensitive bag failure, show the environment that temperature-sensitive bag to be detected is presently in
Temperature is not low, and the temperature-sensitive bag failure that temperature-sensitive bag to be detected occurs is due to caused by temperature-sensitive bag itself to be detected, namely to be detected
Temperature-sensitive bag really occurs in that temperature-sensitive bag failure, in this case, exports for pointing out temperature-sensitive bag to be detected the event of temperature-sensitive bag occur
The prompt message of barrier, normally reports failure.
When being located at temperature-sensitive bag to be detected in other temperature-sensitive bags of same air-conditioner set, occur and temperature-sensitive bag phase to be detected
With temperature-sensitive bag failure when, then judge that the temperature-sensitive bag failure that temperature-sensitive bag to be detected occurs is probably caused by low temperature environment, at this
In the case of kind, the temperature-sensitive bag failure of temperature-sensitive bag to be detected is shielded, stops carrying out fault detect to temperature-sensitive bag to be detected.
In summary, the invention discloses a kind of temperature-sensitive bag fault detection system, when air-conditioner set is shut down, if to be detected
There is temperature-sensitive bag failure in temperature-sensitive bag, then continues to judge other temperature-sensitive bags in air-conditioner set with the temperature-sensitive bag same type to be detected
Whether occur the temperature-sensitive bag failure, if the temperature-sensitive bag failure occurs for other temperature-sensitive bags, judge temperature-sensitive bag to be detected
Temperature-sensitive bag failure caused by low temperature environment, now, to shield temperature-sensitive bag failure, stop carrying out failure inspection to temperature-sensitive bag to be detected
Survey, if there is the temperature-sensitive bag that temperature-sensitive bag failure does not occur in other temperature-sensitive bags, judge temperature-sensitive bag failure not low temperature environment
It is caused, now, export the prompt message of temperature-sensitive bag failure.The present invention is located at same unit by judging with temperature-sensitive bag to be detected
Same type other temperature-sensitive bags, if occur with temperature-sensitive bag identical temperature-sensitive bag failure to be detected, to determine sense to be detected
