Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment shall fall within the protection scope of the present invention.
Compressor of air conditioner can play the role of compressible drive refrigerant in air conditioning coolant loop.Compressor of air conditioner one
As in the outdoor unit of the air conditioner, refrigerant from low-pressure area can be extracted, it is solidifying to be sent to higher-pressure region cooling after compression
Knot, is then given out by cooling fin in heat to air, refrigerant also becomes liquid, pressure rise from gaseous state at this time.Air-conditioning
When compressor gives out heat to air by cooling fin, the delivery temperature of compressor of air conditioner can be used for characterizing compressor of air conditioner
Working condition.In compressor of air conditioner working condition exception, delivery temperature will be typically higher than compressor of air conditioner normal work
When delivery temperature, therefore can be realized by monitoring the delivery temperature of compressor of air conditioner to compressor of air conditioner working condition
Monitoring.
In the prior art, it can generally be controlled by the way that temperature detect switch (TDS) is configured in compressor of air conditioner (A types compressor)
Compressor exhaust temperature, and when temperature detect switch (TDS) disconnects, export alarm command；It or can be by compressor of air conditioner (B types
Compressor) in configuration temperature sensor, for monitoring the delivery temperature of compressor of air conditioner, and the temperature arrived in temperature sensor monitors
When degree is higher than preset temperature threshold, alarm command is exported.
In the prior art, A types compressor is different with the hardware protection circuit of B type compressors, and therefore, it is necessary to using not
Same software code is controlled, and the versatility of software code is poor.And alarm control method provided in an embodiment of the present invention is then
The compressor of above two type can be common to, the versatility that protection control is carried out to compressor can be improved.
Below in conjunction with the accompanying drawings, by specific embodiment and its application scenarios to a kind of alarm provided in an embodiment of the present invention
Control method, device and air-conditioner controller are described in detail.
One embodiment of the invention provides a kind of alarm control method, as shown in Figure 1, including：
The current state of S101, alarm control unit detection temperature detect switch (TDS), the current state of temperature detect switch (TDS) is off-state
Or closed state.
Wherein, alarm control unit does not know the model of compressor of air conditioner (i.e. uncertain compressor of air conditioner is the compression of A types
Machine either B types compressor), it can first detect the current state of temperature detect switch (TDS) when starting detection；Due to A type compressors
In be configured with temperature detect switch (TDS), there is no jointing temp sensor, and be only configured in the hardware protection circuit of B type compressors temperature biography
Sensor does not connect temperature detect switch (TDS)；Therefore, if detecting, temperature detect switch (TDS) is in closed state, and it is A that can determine compressor of air conditioner
Type compressor (performs S104), if detecting, temperature detect switch (TDS) is off, and can not temporarily determine compressor of air conditioner
Model, then need to continue to obtain temperature sensor monitors to temperature (performing S102).
If S102, alarm control unit detect that temperature detect switch (TDS) is off, obtain temperature sensor monitors and arrive
Temperature.
Wherein, if alarm control unit detects that temperature detect switch (TDS) is off, compressor of air conditioner can not be temporarily determined
Model, it is therefore desirable to continue to obtain the temperature that arrives of temperature sensor monitors, due to there is no jointing temp sensing in A type compressors
Device, and it is configured with temperature sensor in the hardware protection circuit of B type compressors；Therefore, if alarm control unit can obtain
The temperature arrived to temperature sensor monitors, then it is B type compressors that can determine compressor of air conditioner；If alarm control unit does not have
The temperature that temperature sensor monitors arrive is got, then it is A type compressors that can determine compressor of air conditioner.Wherein, controlling alarm
Device does not get the temperature that temperature sensor monitors arrive, it can be understood as the temperature got is not or not preset temperature section
It is interior.
If for the temperature that S103, temperature sensor monitors arrive not in preset temperature section, alarm control unit sends out report
Alert signal.
Wherein, the temperature got in preset temperature section, does not specifically include：The temperature got is higher than preset temperature
The upper limit value in section；Alternatively, the temperature value got is zero.
Illustratively, if alarm control unit detects that temperature detect switch (TDS) is off, and gets temperature sensor
The temperature monitored is higher than the upper limit value in preset temperature section, then it is B type compressors that can determine compressor of air conditioner；For B
For type compressor, if the temperature that temperature sensor monitors arrive is higher than preset temperature threshold (the i.e. upper limit in preset temperature section
Value), then it needs to send out alarm signal.
If alarm control unit detects that temperature detect switch (TDS) is off, and gets the temperature that temperature sensor monitors arrive
Degree is zero, i.e., cannot get the temperature that temperature sensor monitors arrive, then it is A type compressors that can determine compressor of air conditioner；
For A type compressors, if temperature detect switch (TDS) is off, need to send out alarm signal.
If the detection of S104, alarm control unit states temperature detect switch (TDS) and is in closed state, and is detecting that temperature detect switch (TDS) is in
After closed state, detect that temperature detect switch (TDS) is off, then send out alarm signal.
Alarm control method provided in an embodiment of the present invention can detect the current state of temperature detect switch (TDS)；If detect temperature
Control switch is off, and the temperature that temperature sensor monitors arrive then sends out alarm signal higher than preset temperature threshold；Or
Person, if detecting, temperature detect switch (TDS) is in the closed state, and after detecting that temperature detect switch (TDS) is in closed state, detects temperature
Control switch is off, then sends out alarm signal.
Due to being only configured with temperature sensor in the hardware protection circuit of B type compressors, temperature detect switch (TDS) is not connect, and A
Temperature detect switch (TDS) is configured in the hardware protection circuit of type compressor, does not have jointing temp sensor；Therefore detecting that temperature control opens
It closes after closed state, then can determine that current compressor for A type compressors, then can continue to detect that temperature control is opened
After pass is off, alarm signal is sent out.When detecting that temperature detect switch (TDS) is off for the first time, then can not determine to work as
Which kind of type compressor preceding compressor is.At this point, it can then obtain the temperature that temperature sensor monitors arrive；If current compression
Machine be A type compressors, then can not get temperature sensor monitors to temperature (temperature got can be interpreted as
Not in preset temperature section), then it can send out alarm signal；If current compressor is B type compressors, if get
Temperature is not in preset temperature section, then it represents that the working temperature abnormity of compressor can then send out alarm signal.
Based on foregoing description, either A types compressor or B type compressors, may be used this programme to its into
Trip temperature monitors, and in the working temperature abnormity of compressor, sends out alarm signal.It can be seen that it can be carried by this programme
Height carries out compressor the versatility of protection control.
Another embodiment of the present invention provides a kind of alarm control method, as shown in Fig. 2, including：
The current state of S201, alarm control unit detection temperature detect switch (TDS), the current state of temperature detect switch (TDS) is off-state
Or closed state.
Wherein, alarm control unit does not know the model of compressor of air conditioner (i.e. uncertain compressor of air conditioner is the compression of A types
Machine either B types compressor), it can first detect the current state of temperature detect switch (TDS) when starting detection.
If S202, alarm control unit detect that temperature detect switch (TDS) is off, obtain temperature sensor monitors and arrive
Temperature.
Due to being configured with temperature detect switch (TDS) in A type compressors, there is no a jointing temp sensor, and the hardware of B type compressors
Temperature sensor is only configured in protection circuit, does not connect temperature detect switch (TDS)；Therefore, if detecting that temperature detect switch (TDS) is in disconnects shape
State, can not temporarily determine the model of compressor of air conditioner, then needs to continue to obtain the temperature that temperature sensor monitors arrive.
Wherein, alarm control unit can periodically acquire the temperature that temperature sensor monitors arrive, and then judge that temperature passes
Whether the temperature that sensor monitors is in preset temperature section.
Illustratively, the temperature got can specifically include not in preset temperature section：The temperature got is higher than
The upper limit value in preset temperature section；Alternatively, the temperature value got is zero.
It should be noted that due to being configured with temperature detect switch (TDS) in A type compressors, there is no jointing temp sensor, B type pressures
Temperature sensor is only configured in the hardware protection circuit of contracting machine, does not connect temperature detect switch (TDS)；Therefore, if alarm control unit detects
It is off to temperature detect switch (TDS), then may be the A types compressor at this time since compressor of air conditioner is A type compressors
Temperature detect switch (TDS) disconnects；It is also likely to be since compressor of air conditioner is B type compressors, B type compressors do not connect temperature detect switch (TDS), because
This can't detect the temperature switch circuit of closure, it may be considered that compressor of air conditioner is off.If it follows that alarm
Control device detects that temperature detect switch (TDS) is off, and alarm control unit is the model that can not determine compressor of air conditioner,
It is B types compressor or A type compressors that can not determine compressor of air conditioner.
If S203, alarm control unit judge to obtain temperature that temperature sensor monitors arrive not in preset temperature section,
Then continue to judge temperature that temperature sensor monitors arrive whether in preset temperature section.
It should be noted that the working condition that some emergency situations may result in compressor of air conditioner is abnormal, so as to cause
The delivery temperature mutation of compressor of air conditioner so that alarm control unit judges to obtain temperature that temperature sensor monitors arrive not pre-
If in temperature range；At this point, the working condition of compressor of air conditioner may be converted within a certain period of time to normal condition, accordingly
Its delivery temperature also can be normal.During in order to avoid the delivery temperature of compressor of air conditioner being caused to be mutated due to above-mentioned time burst, report
Alert control device sends out alarm signal, and alarm control unit can be in the temperature that temperature sensor monitors arrive in the embodiment of the present invention
After not in preset temperature section, continue to judge temperature that temperature sensor monitors arrive whether in preset temperature section, directly
The temperature monitored in the first preset time to temperature sensor not in preset temperature section, just send out by alarm control unit
Go out alarm signal.
If the temperature that S204, temperature sensor monitor in the first preset time is not in preset temperature section, report
Alert control device then sends out alarm signal.
If alarm control unit detects that temperature detect switch (TDS) is off, and gets the temperature that temperature sensor monitors arrive
For degree higher than the upper limit value in preset temperature section, then it is B type compressors that can determine compressor of air conditioner；For B type compressors
For, if the temperature that temperature sensor monitors arrive is needed higher than preset temperature threshold (i.e. the upper limit value in preset temperature section)
Send out alarm signal.
If alarm control unit detects that temperature detect switch (TDS) is off, and gets the temperature that temperature sensor monitors arrive
Degree is zero, i.e., cannot get the temperature that temperature sensor monitors arrive, then it is A type compressors that can determine compressor of air conditioner；
For A type compressors, if temperature detect switch (TDS) is off, need to send out alarm signal.
When alarm control unit detects that temperature detect switch (TDS) is in closed state, then it is A types that can determine compressor of air conditioner
Compressor；At this point, alarm control unit can then continue to detect the state of temperature detect switch (TDS), the method for the specific embodiment of the present invention
It can include S205：
If S205, alarm control unit detect temperature detect switch (TDS) and are in closed state, and are detecting that temperature detect switch (TDS) is in
After closed state, the current state of the temperature detect switch (TDS) detected in the second preset time is off-state, then sends out alarm
Signal.
It should be noted that it is empty that the first preset time and the second preset time in the embodiment of the present invention, which can be user,
Adjust the time parameter of compressor configuration, or the time parameter being pre-configured to be in air-conditioner controller.First preset time and
Second preset time may be the same or different, and the embodiment of the present invention is without limitation.Alarm in the embodiment of the present invention
Control device can be air-conditioner controller.
Alarm control method provided in an embodiment of the present invention can detect the current state of temperature detect switch (TDS)；If detect temperature
Control switch is off, and the temperature that temperature sensor monitors arrive then sends out alarm signal higher than preset temperature threshold；Or
Person, if detecting, temperature detect switch (TDS) is in the closed state, and after detecting that temperature detect switch (TDS) is in closed state, detects temperature
Control switch is off, then sends out alarm signal.
Due to being only configured with temperature sensor in the hardware protection circuit of B type compressors, temperature detect switch (TDS) is not connect, and A
Temperature detect switch (TDS) is configured in the hardware protection circuit of type compressor, does not have jointing temp sensor；Therefore detecting that temperature control opens
It closes after closed state, then can determine that current compressor for A type compressors, then can continue to detect that temperature control is opened
After pass is off, alarm signal is sent out.When detecting that temperature detect switch (TDS) is off for the first time, then can not determine to work as
Which kind of type compressor preceding compressor is.At this point, it can then obtain the temperature that temperature sensor monitors arrive；If current compression
Machine be A type compressors, then can not get temperature sensor monitors to temperature (temperature got can be interpreted as
Not in preset temperature section), then it can send out alarm signal；If current compressor is B type compressors, if get
Temperature is not in preset temperature section, then it represents that the working temperature abnormity of compressor can then send out alarm signal.
Based on foregoing description, either A types compressor or B type compressors, may be used this programme to its into
Trip temperature monitors, and in the working temperature abnormity of compressor, sends out alarm signal.It can be seen that it can be carried by this programme
Height carries out compressor the versatility of protection control.
