Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The air conditioning compressor may function to compress a driving refrigerant in the air conditioning refrigerant circuit. An air conditioner compressor is generally installed in an outdoor unit of an air conditioner, and is configured to extract a refrigerant from a low pressure region, compress the refrigerant, send the compressed refrigerant to a high pressure region for cooling and condensation, and then radiate heat to air through a heat radiating fin, where the refrigerant is also changed from a gas state to a liquid state, and the pressure of the refrigerant is increased. When the air conditioning compressor emits heat to the air through the heat radiating fins, the exhaust temperature of the air conditioning compressor can be used for representing the working state of the air conditioning compressor. When the working state of the air conditioner compressor is abnormal, the exhaust temperature of the air conditioner compressor is generally higher than that of the air conditioner compressor in normal working, so that the working state of the air conditioner compressor can be monitored by monitoring the exhaust temperature of the air conditioner compressor.
In the prior art, a temperature control switch is generally configured in an air conditioner compressor (A type compressor) to control the exhaust temperature of the compressor, and when the temperature control switch is switched off, an alarm instruction is output; or a temperature sensor is configured in the air-conditioning compressor (B type compressor) to monitor the exhaust temperature of the air-conditioning compressor, and when the temperature monitored by the temperature sensor is higher than a preset temperature threshold value, an alarm instruction is output.
In the prior art, hardware protection circuits of a type A compressor and a type B compressor are different, so that different software codes are required to be used for control, and the universality of the software codes is poor. The alarm control method provided by the embodiment of the invention can be universally used for the two types of compressors, and the universality of protection control on the compressors can be improved.
An alarm control method, an alarm control device and an air conditioner controller provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
An embodiment of the present invention provides an alarm control method, as shown in fig. 1, including:
s101, detecting the current state of the temperature control switch by the alarm control device, wherein the current state of the temperature control switch is an open state or a closed state.
The alarm control device does not determine the type of the air-conditioning compressor (namely, the air-conditioning compressor is not determined to be an A type compressor or a B type compressor), and can detect the current state of the temperature control switch firstly when the detection is started; because the A type compressor is provided with the temperature control switch and is not connected with the temperature sensor, the hardware protection circuit of the B type compressor is only provided with the temperature sensor and is not connected with the temperature control switch; therefore, if the temperature control switch is detected to be in the closed state, it may be determined that the air conditioner compressor is the type a compressor (i.e., S104 is performed), and if the temperature control switch is detected to be in the open state, it is temporarily not possible to determine the type of the air conditioner compressor, it is necessary to continuously acquire the temperature monitored by the temperature sensor (i.e., S102 is performed).
S102, if the alarm control device detects that the temperature control switch is in the off state, acquiring the temperature monitored by the temperature sensor.
If the alarm control device detects that the temperature control switch is in an off state, the model of the air conditioner compressor cannot be determined temporarily, so that the temperature monitored by the temperature sensor needs to be obtained continuously; therefore, if the alarm control device can acquire the temperature monitored by the temperature sensor, the air-conditioning compressor can be determined to be a B-type compressor; and if the alarm control device does not acquire the temperature monitored by the temperature sensor, determining that the air conditioner compressor is the A-type compressor. The alarm control device does not acquire the temperature monitored by the temperature sensor, and the acquired temperature is not within a preset temperature interval.
S103, if the temperature monitored by the temperature sensor is not within the preset temperature range, the alarm control device sends out an alarm signal.
Wherein, the temperature of acquireing is not in presetting the temperature interval, specifically includes: the obtained temperature is higher than the upper limit value of a preset temperature interval; or the acquired temperature value is zero.
For example, if the alarm control device detects that the temperature control switch is in an off state and obtains that the temperature monitored by the temperature sensor is higher than an upper limit value of a preset temperature interval, the air-conditioning compressor can be determined to be a B-type compressor; for a B-type compressor, if the temperature monitored by the temperature sensor is higher than a preset temperature threshold (i.e., an upper limit value of a preset temperature interval), an alarm signal needs to be sent.
If the alarm control device detects that the temperature control switch is in an off state and the temperature monitored by the temperature sensor is zero, namely the temperature monitored by the temperature sensor cannot be acquired, the air-conditioning compressor can be determined to be an A type compressor; for the type a compressor, if the temperature control switch is in an off state, an alarm signal needs to be sent out.
And S104, if the alarm control device detects that the temperature control switch is in a closed state and detects that the temperature control switch is in an open state after detecting that the temperature control switch is in the closed state, sending an alarm signal.
The alarm control method provided by the embodiment of the invention can detect the current state of the temperature control switch; if the temperature control switch is detected to be in a disconnected state and the temperature monitored by the temperature sensor is higher than a preset temperature threshold value, an alarm signal is sent out; or if the temperature control switch is detected to be in the closed state and the temperature control switch is detected to be in the open state after the temperature control switch is detected to be in the closed state, an alarm signal is sent.
The hardware protection circuit of the B type compressor is only provided with a temperature sensor and is not connected with a temperature control switch, and the hardware protection circuit of the A type compressor is provided with a temperature control switch and is not connected with a temperature sensor; therefore, after the temperature control switch is detected to be in the closed state, the current compressor can be determined to be the A type compressor, and an alarm signal can be sent out after the temperature control switch is continuously detected to be in the open state. When the temperature control switch is detected to be in an off state for the first time, the type of the current compressor cannot be determined. At this time, the temperature monitored by the temperature sensor can be obtained; if the current compressor is an A-type compressor, the temperature monitored by the temperature sensor cannot be acquired (namely, the acquired temperature is not within a preset temperature interval), and an alarm signal can be sent out; if the current compressor is a B-type compressor, if the obtained temperature is not within the preset temperature range, the working temperature of the compressor is abnormal, and an alarm signal can be sent.
Based on the above description, no matter the model A compressor or the model B compressor, the scheme can be adopted to monitor the temperature of the compressor and send out an alarm signal when the working temperature of the compressor is abnormal. Therefore, the universality of protection control on the compressor can be improved through the scheme.
Another embodiment of the present invention provides an alarm control method, as shown in fig. 2, including:
s201, the alarm control device detects the current state of the temperature control switch, and the current state of the temperature control switch is an open state or a closed state.
The alarm control device does not determine the type of the air-conditioning compressor (namely, the air-conditioning compressor is not determined to be an A type compressor or a B type compressor), and can detect the current state of the temperature control switch firstly when the detection is started.
S202, if the alarm control device detects that the temperature control switch is in the off state, the temperature monitored by the temperature sensor is obtained.
Because the A type compressor is provided with the temperature control switch and is not connected with the temperature sensor, the hardware protection circuit of the B type compressor is only provided with the temperature sensor and is not connected with the temperature control switch; therefore, if the temperature control switch is detected to be in the off state, and the model of the air conditioner compressor cannot be determined temporarily, the temperature monitored by the temperature sensor needs to be acquired continuously.
The alarm control device can periodically acquire the temperature monitored by the temperature sensor and then judge whether the temperature monitored by the temperature sensor is within a preset temperature interval.
Illustratively, the obtaining the temperature not within the preset temperature interval may specifically include: the obtained temperature is higher than the upper limit value of a preset temperature interval; or the acquired temperature value is zero.
It should be noted that, because the temperature control switch is configured in the a-type compressor, the temperature sensor is not connected, and the temperature sensor is only configured in the hardware protection circuit of the B-type compressor, and the temperature control switch is not connected; therefore, if the alarm control device detects that the temperature control switch is in the off state, the air conditioner compressor is probably the type A compressor, and the temperature control switch of the type A compressor is off at the moment; the air conditioner compressor may be a B-type compressor, and the B-type compressor is not connected to the temperature control switch, so that the air conditioner compressor may be considered to be in an off state if a closed temperature control switch circuit is not detected. Therefore, if the alarm control device detects that the temperature control switch is in an off state, the alarm control device cannot determine the type of the air conditioner compressor, namely cannot determine whether the air conditioner compressor is a B type compressor or an A type compressor.
And S203, if the alarm control device judges that the temperature monitored by the temperature sensor is not in the preset temperature interval, continuously judging whether the temperature monitored by the temperature sensor is in the preset temperature interval.
It should be noted that some emergency situations may cause the working state of the air-conditioning compressor to be abnormal, so that the exhaust temperature of the air-conditioning compressor is suddenly changed, and the alarm control device determines that the temperature monitored by the temperature sensor is not within the preset temperature range; at this time, the operating state of the air conditioner compressor may be changed to a normal state within a certain time, and accordingly, the discharge temperature thereof may be normal. In order to avoid that the alarm control device sends an alarm signal when the exhaust temperature of the air conditioner compressor suddenly changes due to the burst time, the alarm control device in the embodiment of the invention can continuously judge whether the temperature monitored by the temperature sensor is in the preset temperature interval after the temperature monitored by the temperature sensor is not in the preset temperature interval, and the alarm control device does not send the alarm signal until the temperature monitored by the temperature sensor in the first preset time is not in the preset temperature interval.
And S204, if the temperatures monitored by the temperature sensors within the first preset time are not within the preset temperature interval, the alarm control device sends out alarm signals.
If the alarm control device detects that the temperature control switch is in a disconnected state and obtains that the temperature monitored by the temperature sensor is higher than an upper limit value of a preset temperature interval, the air-conditioning compressor can be determined to be a B-type compressor; for a B-type compressor, if the temperature monitored by the temperature sensor is higher than a preset temperature threshold (i.e., an upper limit value of a preset temperature interval), an alarm signal needs to be sent.
If the alarm control device detects that the temperature control switch is in an off state and the temperature monitored by the temperature sensor is zero, namely the temperature monitored by the temperature sensor cannot be acquired, the air-conditioning compressor can be determined to be an A type compressor; for the type a compressor, if the temperature control switch is in an off state, an alarm signal needs to be sent out.
When the alarm control device detects that the temperature control switch is in a closed state, the air conditioner compressor can be determined to be an A type compressor; at this time, the alarm control device may continue to detect the state of the temperature control switch, and the method according to the embodiment of the present invention may specifically include step S205:
and S205, if the alarm control device detects that the temperature control switch is in the closed state and detects that the temperature control switch is in the closed state, and the current states of the temperature control switch detected within the second preset time are all in the open state, sending an alarm signal.
It should be noted that the first preset time and the second preset time in the embodiment of the present invention may be time parameters configured by a user for an air conditioner compressor, or may also be time parameters preconfigured in an air conditioner controller. The first preset time and the second preset time may be the same or different, and the embodiment of the present invention is not limited thereto. The alarm control device in the embodiment of the invention can be an air conditioner controller.
The alarm control method provided by the embodiment of the invention can detect the current state of the temperature control switch; if the temperature control switch is detected to be in a disconnected state and the temperature monitored by the temperature sensor is higher than a preset temperature threshold value, an alarm signal is sent out; or if the temperature control switch is detected to be in the closed state and the temperature control switch is detected to be in the open state after the temperature control switch is detected to be in the closed state, an alarm signal is sent.
The hardware protection circuit of the B type compressor is only provided with a temperature sensor and is not connected with a temperature control switch, and the hardware protection circuit of the A type compressor is provided with a temperature control switch and is not connected with a temperature sensor; therefore, after the temperature control switch is detected to be in the closed state, the current compressor can be determined to be the A type compressor, and an alarm signal can be sent out after the temperature control switch is continuously detected to be in the open state. When the temperature control switch is detected to be in an off state for the first time, the type of the current compressor cannot be determined. At this time, the temperature monitored by the temperature sensor can be obtained; if the current compressor is an A-type compressor, the temperature monitored by the temperature sensor cannot be acquired (namely, the acquired temperature is not within a preset temperature interval), and an alarm signal can be sent out; if the current compressor is a B-type compressor, if the obtained temperature is not within the preset temperature range, the working temperature of the compressor is abnormal, and an alarm signal can be sent.
Based on the above description, no matter the model A compressor or the model B compressor, the scheme can be adopted to monitor the temperature of the compressor and send out an alarm signal when the working temperature of the compressor is abnormal. Therefore, the universality of protection control on the compressor can be improved through the scheme.
Another embodiment of the present invention provides an alarm control apparatus, as shown in fig. 3, including: a detection unit 31, a first alarm unit 32 and a second alarm unit 33.
The detection unit 31 is configured to detect a current state of the temperature controlled switch, where the current state of the temperature controlled switch is an open state or a closed state.
The first alarm unit 32 is configured to obtain the temperature monitored by the temperature sensor if the detection unit 31 detects that the temperature control switch is in the off state, send an alarm signal if the temperature monitored by the temperature sensor is not within a preset temperature interval, and the preset temperature interval is used for representing the exhaust temperature of the air conditioner compressor during normal operation.
The second alarm unit 33 is configured to send an alarm signal if the detection unit 31 detects that the temperature control switch is in the closed state, and after the detection unit 31 detects that the temperature control switch is in the closed state, the detection unit detects that the temperature control switch is in the open state.
Further, the first alarm unit 32 is specifically configured to:

The alarm control device provided by the embodiment of the invention can detect the current state of the temperature control switch; if the temperature control switch is detected to be in a disconnected state and the temperature monitored by the temperature sensor is higher than a preset temperature threshold value, an alarm signal is sent out; or if the temperature control switch is detected to be in the closed state and the temperature control switch is detected to be in the open state after the temperature control switch is detected to be in the closed state, an alarm signal is sent.
The hardware protection circuit of the B type compressor is only provided with a temperature sensor and is not connected with a temperature control switch, and the hardware protection circuit of the A type compressor is provided with a temperature control switch and is not connected with a temperature sensor; therefore, after the temperature control switch is detected to be in the closed state, the current compressor can be determined to be the A type compressor, and an alarm signal can be sent out after the temperature control switch is continuously detected to be in the open state. When the temperature control switch is detected to be in an off state for the first time, the type of the current compressor cannot be determined. At this time, the temperature monitored by the temperature sensor can be obtained; if the current compressor is an A-type compressor, the temperature monitored by the temperature sensor cannot be acquired (namely, the acquired temperature is not within a preset temperature interval), and an alarm signal can be sent out; if the current compressor is a B-type compressor, if the obtained temperature is not within the preset temperature range, the working temperature of the compressor is abnormal, and an alarm signal can be sent.
Based on the above description, no matter the model A compressor or the model B compressor, the scheme can be adopted to monitor the temperature of the compressor and send out an alarm signal when the working temperature of the compressor is abnormal. Therefore, the universality of protection control on the compressor can be improved through the scheme.

the obtained temperature is higher than the upper limit value of the preset temperature interval; or,
the obtained temperature value is zero.
It should be noted that, for specific description of some functional modules in the air conditioner controller provided in the embodiment of the present invention, reference may be made to corresponding contents in the method embodiment, and details are not described here again.
The alarm control method, the alarm control device and the air conditioner controller provided by the embodiment of the invention can detect the current state of the temperature control switch; if the temperature control switch is detected to be in a disconnected state and the temperature monitored by the temperature sensor is higher than a preset temperature threshold value, an alarm signal is sent out; or if the temperature control switch is detected to be in the closed state and the temperature control switch is detected to be in the open state after the temperature control switch is detected to be in the closed state, an alarm signal is sent.
The hardware protection circuit of the B type compressor is only provided with a temperature sensor and is not connected with a temperature control switch, and the hardware protection circuit of the A type compressor is provided with a temperature control switch and is not connected with a temperature sensor; therefore, after the temperature control switch is detected to be in the closed state, the current compressor can be determined to be the A type compressor, and an alarm signal can be sent out after the temperature control switch is continuously detected to be in the open state. When the temperature control switch is detected to be in an off state for the first time, the type of the current compressor cannot be determined. At this time, the temperature monitored by the temperature sensor can be obtained; if the current compressor is an A-type compressor, the temperature monitored by the temperature sensor cannot be acquired (namely, the acquired temperature is not within a preset temperature interval), and an alarm signal can be sent out; if the current compressor is a B-type compressor, if the obtained temperature is not within the preset temperature range, the working temperature of the compressor is abnormal, and an alarm signal can be sent.
Based on the above description, no matter the model A compressor or the model B compressor, the scheme can be adopted to monitor the temperature of the compressor and send out an alarm signal when the working temperature of the compressor is abnormal. Therefore, the universality of protection control on the compressor can be improved through the scheme.
