Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer and more complete, the technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention, and based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the scope of the present invention.
Fig. 1 is a flowchart of a method for processing a sampled value of an air conditioner temperature sensor according to an embodiment of the present invention, as shown in fig. 1, the method may include the following steps:
102, acquiring a second temperature sampling value of a second temperature sensor at a refrigerant inlet of the air conditioner;
103, acquiring a third temperature sampling value of a third temperature sensor at an outdoor unit air pipe of the air conditioner;
104, judging whether the first temperature sampling value exceeds a preset temperature threshold value, if so, executing a step 105, otherwise, executing a step 106;
and 106, determining the second temperature sampling value as the target temperature at the refrigerant inlet or taking the third temperature sampling value as the target temperature at the air pipe of the outdoor unit.
In the embodiment of the invention, a first temperature sampling value of a first temperature sensor at an exhaust pipe of the air conditioner is obtained, a second temperature sampling value of a second temperature sensor at a refrigerant inlet of the air conditioner is obtained, and a third temperature sampling value of a third temperature sensor at an outdoor unit air pipe of the air conditioner is obtained. Judging whether the first temperature sampling value exceeds a preset temperature threshold value, if so, determining the first temperature sampling value as the target temperature at the refrigerant inlet or the outdoor unit air pipe because the first temperature sampling value is not in the normal working sampling range of the second temperature sensor or the third temperature sensor, the second temperature sampling value acquired by the second temperature sensor at the refrigerant inlet or the third temperature sampling value acquired by the third temperature sensor at the outdoor unit air pipe is inaccurate, and the first temperature sampling value is close to the temperature value at the refrigerant inlet or the outdoor unit air pipe; if the first temperature sampling value does not exceed the temperature threshold value, the temperature value acquired by the second temperature sensor at the refrigerant inlet or the third temperature sensor at the outdoor unit air pipe is within the normal working sampling value range, so that the second temperature sampling value can be determined as the target temperature at the refrigerant inlet or the third temperature sampling value can be used as the target temperature at the outdoor unit air pipe. The invention can improve the accuracy of the temperature sampling value.
In an embodiment of the present invention, a method for processing a sampled value of an air conditioner temperature sensor based on the method shown in fig. 1, when the first temperature sampled value exceeds a preset temperature threshold, includes:
if the air conditioner is in a heating mode, determining the first temperature sampling value as a target temperature at the refrigerant inlet;
and if the air conditioner is in a cooling mode, determining the first temperature sampling value as the target temperature at the air pipe of the outdoor unit.
In the embodiment of the invention, when the first temperature sampling value exceeds the preset temperature threshold, the second temperature sampling value acquired by the second temperature sensor at the refrigerant inlet or the third temperature sampling value acquired by the third temperature sensor at the outdoor air pipe cannot accurately represent the actual temperature value. When the air conditioner is in a heating mode, the temperature of a refrigerant inlet of the evaporator is close to the exhaust temperature in the whole heating process, and the temperature of an outdoor unit air pipe is lower than the outdoor temperature, so that the exhaust temperature can be used as the temperature of the refrigerant inlet, namely a first temperature sampling value is determined as the target temperature of the refrigerant inlet; when the air conditioner is in a refrigeration mode, the temperature of an outdoor unit air pipe is close to the exhaust temperature in the whole refrigeration process, and the temperature of a refrigerant inlet of an evaporator is lower than the room temperature, so that the exhaust temperature can be used as the temperature of the outdoor unit air pipe, namely, a first temperature sampling value is determined as the target temperature of the outdoor unit air pipe, and the target temperature of the position to be detected can be accurately determined when a second temperature sensor or a third temperature sensor exceeds a temperature acquisition interval.
In an embodiment of the present invention, a method for processing a sampled value of an air conditioner temperature sensor based on the method shown in fig. 1, when the first temperature sampled value does not exceed a preset temperature threshold, includes:
if the air conditioner is in a heating mode, determining the second temperature sampling value as the target temperature of the refrigerant inlet;
and if the air conditioner is in a cooling mode, determining the second temperature sampling value as the target temperature at the air pipe of the outdoor unit.
In the embodiment of the invention, when the first temperature sampling value does not exceed the preset temperature threshold, the second temperature sampling value acquired by the second temperature sensor at the refrigerant inlet or the third temperature sampling value acquired by the third temperature sensor at the outdoor unit air pipe can accurately represent the actual temperature value. When the air conditioner is in a heating mode, determining a second temperature sampling value as a target temperature at a refrigerant inlet; when the air conditioner is in a refrigeration mode, the second temperature sampling value is determined as the target temperature of the air pipe of the outdoor unit, and the temperature value acquired by the second temperature sensor or the third temperature sensor at the position to be measured can be guaranteed to accurately represent the target temperature.
In an embodiment of the present invention, after the acquiring a first temperature sample value of a first temperature sensor at an exhaust pipe of an air conditioner and before the determining whether the first temperature sample value exceeds a preset temperature threshold, the method for processing a sample value of a temperature sensor of an air conditioner as shown in fig. 1 further includes:
determining whether the resistance value of the first temperature sensor when the first temperature sampling value is in a preset resistance value range or not according to the first temperature sampling value and a preset resistance value temperature corresponding table, wherein the resistance value temperature corresponding table is used for representing the corresponding relation between the resistance value and the temperature;
if the resistance value is within the resistance value range, determining that the first temperature sensor is normal;
and if the resistance value is not in the resistance value range, determining that the first temperature sensor is abnormal.
In the embodiment of the invention, when a first temperature sampling value acquired by the first temperature sensor at the exhaust pipe of the air conditioner is acquired, whether the first temperature sensor is normal or not is judged according to the acquired first temperature sampling value and a preset resistance value temperature corresponding table. If the first temperature sensor is normal, whether the first temperature sampling value exceeds a preset temperature threshold value can be further judged; if the first temperature sensor is abnormal, the first temperature sensor is considered to be in fault, and the first temperature sampling value cannot be used as the exhaust temperature or the target temperature at the position to be measured continuously. Specifically, the resistance value and temperature correspondence table stores the correspondence between the resistance value and the temperature, and when the resistance value corresponding to the first temperature sampling value is within a preset resistance value range, the first temperature sensor is determined to be normal, otherwise, the first temperature sensor is determined to be abnormal. The first temperature sampling value acquired by the first temperature sensor is of great importance in the invention, so that the accuracy of the target temperature at the position to be measured can be ensured when the first temperature sensor is determined to be normal.
Based on the method for processing the sampling value of the air conditioner temperature sensor shown in fig. 1, in one embodiment of the invention, if the first temperature sampling value exceeds the temperature threshold value, the second temperature sensor or the third temperature sensor generates a fault signal;
if the first temperature sampling value exceeds the temperature threshold value, taking the first temperature sampling value as a target temperature at the refrigerant inlet or the outdoor unit air pipe, including:
and if the first temperature sampling value exceeds the temperature threshold value, taking the fault signal as a normal signal, and taking the first temperature sampling value as the target temperature at the refrigerant inlet or the air pipe of the outdoor unit.
In the embodiment of the invention, when the first temperature sampling value exceeds the preset temperature threshold value, the temperature at the refrigerant inlet or the air pipe of the outdoor unit is not in the temperature sampling interval of the second temperature sensor or the third temperature sensor, and the second temperature sensor or the third temperature sensor can falsely report that the temperature sensor has a fault when being processed according to the normal temperature. Therefore, the fault signal which is mistakenly reported by the second temperature sensor or the third temperature sensor can be used as a normal signal, and the first temperature sampling value is used as the target temperature at the refrigerant inlet or the air pipe of the outdoor unit.
As shown in fig. 2, in order to more clearly illustrate the technical solution and advantages of the present invention, the following describes in detail a sampling value processing method of an air conditioner temperature sensor provided in an embodiment of the present invention, which specifically includes the following steps:
In this step, two types of temperature sensors are generally adopted in the air conditioning system to acquire temperature values, including a first temperature sensor for high temperature detection, specifically a WF4I573-1300 temperature sensor; and the second temperature sensor and the third temperature sensor are used for normal temperature detection, and specifically are WF4I103-1300 temperature sensors. The temperature of the exhaust pipe of the air conditioner belongs to high temperature, so that a first temperature sampling value of the first temperature sensor at the exhaust pipe of the air conditioner is obtained.
In the step, in the refrigeration mode, the temperature at the refrigerant inlet needs to participate in the accurate control of the electronic expansion valve; in the heating mode, the temperature at the refrigerant inlet does not participate in the accurate control of the electronic expansion valve, so that a second temperature sampling value of a second temperature sensor, namely a WF4I103-1300 temperature sensor, at the refrigerant inlet of the air conditioner is obtained.
And step 203, acquiring a third temperature sampling value of a third temperature sensor at an outdoor unit air pipe of the air conditioner.
In the step, in the heating mode, the temperature of the air pipe of the outdoor unit needs to participate in the accurate control of the electronic expansion valve; in the cooling mode, the outdoor unit air pipe temperature does not participate in the precise control of the electronic expansion valve, so that a third temperature sampling value of the third temperature sensor, namely the WF4I103-1300 temperature sensor, at the outdoor unit air pipe of the air conditioner is obtained.
And 204, judging whether the resistance value of the first temperature sensor in the first temperature sampling value is in a preset resistance value range or not according to the first temperature sampling value and a preset resistance value temperature corresponding table, if so, executing step 205, otherwise, ending the current process.
In the step, when a first temperature sampling value acquired by the first temperature sensor at an exhaust pipe of the air conditioner is acquired, whether the first temperature sensor is normal or not is judged according to the acquired first temperature sampling value and a preset resistance value temperature corresponding table. If the first temperature sensor is normal, whether the first temperature sampling value exceeds a preset temperature threshold value can be further judged; if the first temperature sensor is abnormal, the first temperature sensor is considered to be in fault, and the first temperature sampling value cannot be used as the exhaust temperature or the target temperature at the position to be measured continuously. Specifically, the resistance value and temperature correspondence table stores the correspondence between the resistance value and the temperature, and when the resistance value corresponding to the first temperature sampling value is within a preset resistance value range, the first temperature sensor is determined to be normal, otherwise, the first temperature sensor is determined to be abnormal.
For example, the preset resistance temperature mapping table stores a set of resistance temperature mapping relationship corresponding to a resistance of 2k Ω at a temperature of 110 ℃, and the preset resistance variation range is ± 0.2k Ω, so that the resistance range corresponding to 110 ℃ is (1.8k Ω -2.2 k Ω). The acquired first temperature sampling value is 110 ℃, but the corresponding resistance value is 2.5k omega, so that the resistance value 2.5k omega of the first temperature sensor at the temperature of 110 ℃ is determined not to be in the preset resistance value range (1.8k omega-2.2 k omega), and therefore the first temperature sensor is determined to be abnormal, and if the resistance value of the first temperature sensor at the temperature of 110 ℃ is in the preset resistance value range (1.8k omega-2.2 k omega), the first temperature sensor is determined to be normal.
In this step, when the first temperature sampling value exceeds the preset temperature threshold, the second temperature sampling value collected by the second temperature sensor at the refrigerant inlet or the third temperature sampling value collected by the third temperature sensor at the outdoor unit air pipe may not accurately represent the actual temperature value. When the air conditioner is in a heating mode, the temperature of a refrigerant inlet of the evaporator is close to the exhaust temperature in the whole heating process, and the temperature of an outdoor unit air pipe is lower than the outdoor temperature, so that the exhaust temperature can be used as the temperature of the refrigerant inlet, namely a first temperature sampling value is determined as the target temperature of the refrigerant inlet; when the air conditioner is in a refrigeration mode, the temperature of an outdoor air pipe is close to the exhaust temperature in the whole refrigeration process, and the temperature of a refrigerant inlet of an evaporator is lower than the room temperature, so that the exhaust temperature can be used as the temperature of the outdoor air pipe, namely, a first temperature sampling value is determined as the target temperature of the outdoor air pipe. When the first temperature sampling value does not exceed the preset temperature threshold value, the second temperature sampling value acquired by the second temperature sensor at the refrigerant inlet or the third temperature sampling value acquired by the third temperature sensor at the outdoor unit air pipe can accurately represent the actual temperature value. When the air conditioner is in a heating mode, determining a second temperature sampling value as a target temperature at a refrigerant inlet; and when the air conditioner is in a cooling mode, determining the third temperature sampling value as the target temperature at the air pipe of the outdoor unit. In summary, it is necessary to determine whether the first temperature sampling value exceeds a preset temperature threshold, and determine the corresponding temperature sensor at the refrigerant inlet or the air pipe of the outdoor unit according to the determination result.
For example, the preset temperature threshold is 100 ℃, and when the first temperature sampling value is 110 ℃, the preset temperature threshold is exceeded, so that the first temperature sampling value acquired by the first temperature sensor is used as a temperature value at a refrigerant inlet or an outdoor unit air pipe; when the first temperature sampling value is 90 ℃, the first temperature sampling value does not exceed the preset temperature threshold value, and therefore the obtained second temperature sampling value is used as the target temperature at the refrigerant inlet of the air conditioner or the obtained third temperature sampling value is used as the target temperature at the air pipe of the outdoor unit of the air conditioner.
And step 206, judging whether the air conditioner is in a heating mode, if so, executing step 207, otherwise, executing step 208.
In this step, when the air conditioner is in the heating mode, the temperature of the refrigerant inlet of the evaporator is close to the exhaust temperature in the whole heating process, and the temperature of the outdoor unit air pipe is lower than the outdoor temperature; when the air conditioner is not in a heating mode, namely in a cooling mode, the outdoor air pipe temperature is close to the exhaust temperature in the whole cooling process, and the refrigerant inlet temperature of the evaporator is lower than the room temperature. It should be noted that the air conditioner has functions of dehumidification and self-cleaning, but both of these functions are performed by the air conditioner, and therefore, in the present invention, both of the functions of the air conditioner are heating or cooling.
And step 207, taking the fault signal generated by the second temperature sensor as a normal signal and determining the first temperature sampling value as the target temperature at the refrigerant inlet.
In this step, the first temperature sampling value is greater than the preset temperature threshold value, the air conditioner is in a heating mode, the second temperature sensor does not detect the fault of the temperature sensor, and if a fault signal occurs, the fault signal is used as a normal signal. Because the temperature of the refrigerant inlet is equal to the exhaust temperature in the heating mode, the exhaust temperature value acquired by the first temperature sensor at the exhaust pipe of the air conditioner, namely the first temperature sampling value, can be used as the target temperature of the refrigerant inlet.
And step 208, determining the first temperature sampling value as the target temperature at the air pipe of the outdoor unit by taking the fault signal generated by the third temperature sensor as a normal signal.
In this step, the first temperature sampling value is greater than the preset temperature threshold value, the air conditioner is in a cooling mode, the third temperature sensor does not detect the fault of the temperature sensor, and if a fault signal occurs, the fault signal is used as a normal signal. Since the outdoor unit air pipe temperature is equal to the discharge air temperature in the cooling mode, the discharge air temperature value, i.e., the first temperature sampling value, collected by the first temperature sensor at the discharge pipe of the air conditioner can be used as the target temperature at the outdoor unit air pipe.
In this step, the first temperature sampling value does not exceed the preset temperature threshold, and the second temperature sampling value acquired by the second temperature sensor at the refrigerant inlet or the third temperature sampling value acquired by the third temperature sensor at the outdoor unit air pipe can accurately represent the actual temperature value. When the air conditioner is in a heating mode, determining a second temperature sampling value as a target temperature at a refrigerant inlet; and when the air conditioner is in a cooling mode, determining the third temperature sampling value as the target temperature at the air pipe of the outdoor unit. Therefore, the target temperature at the refrigerant inlet or the air pipe of the outdoor unit can be determined according to the working mode of the air conditioner.
And step 210, determining the second temperature sampling value as the target temperature at the refrigerant inlet.
In the step, the first temperature sampling value is not greater than the preset temperature threshold value, the air conditioner is in a heating mode, and the second temperature sampling value acquired by the second temperature sensor at the refrigerant inlet can accurately represent the actual temperature value at the refrigerant inlet. Therefore, the second temperature sampling value can be determined as the target temperature at the refrigerant inlet.
And step 211, determining the third temperature sampling value as the target temperature at the air pipe of the outdoor unit.
In the step, the first temperature sampling value is not greater than the preset temperature threshold value, the air conditioner is in a heating mode, and the third temperature sampling value acquired by the third temperature sensor at the outdoor unit air pipe can accurately represent the actual temperature value at the outdoor unit air pipe. The third temperature sample value can thus be determined as the target temperature at the outdoor unit gas pipe.

In summary, the method and the apparatus for processing the sampling value of the air conditioner temperature sensor according to the embodiments of the present invention at least have the following advantages:
1. in the embodiment of the invention, a first temperature sampling value of a first temperature sensor at an exhaust pipe of the air conditioner is obtained, a second temperature sampling value of a second temperature sensor at a refrigerant inlet of the air conditioner is obtained, and a third temperature sampling value of a third temperature sensor at an outdoor unit air pipe of the air conditioner is obtained. Judging whether the first temperature sampling value exceeds a preset temperature threshold value, if so, determining the first temperature sampling value as the target temperature at the refrigerant inlet or the outdoor unit air pipe because the first temperature sampling value is not in the normal working sampling range of the second temperature sensor or the third temperature sensor, the second temperature sampling value acquired by the second temperature sensor at the refrigerant inlet or the third temperature sampling value acquired by the third temperature sensor at the outdoor unit air pipe is inaccurate, and the first temperature sampling value is close to the temperature value at the refrigerant inlet or the outdoor unit air pipe; if the first temperature sampling value does not exceed the temperature threshold value, the temperature value acquired by the second temperature sensor at the refrigerant inlet or the third temperature sensor at the outdoor unit air pipe is within the normal working sampling value range, so that the second temperature sampling value can be determined as the target temperature at the refrigerant inlet or the third temperature sampling value can be used as the target temperature at the outdoor unit air pipe. The invention can improve the accuracy of the temperature sampling value.
2. In the embodiment of the invention, when the first temperature sampling value exceeds the preset temperature threshold, the second temperature sampling value acquired by the second temperature sensor at the refrigerant inlet or the third temperature sampling value acquired by the third temperature sensor at the outdoor air pipe cannot accurately represent the actual temperature value. When the air conditioner is in a heating mode, the temperature of a refrigerant inlet of the evaporator is close to the exhaust temperature in the whole heating process, and the temperature of an outdoor unit air pipe is lower than the outdoor temperature, so that the exhaust temperature can be used as the temperature of the refrigerant inlet, namely a first temperature sampling value is determined as the target temperature of the refrigerant inlet; when the air conditioner is in a refrigeration mode, the temperature of an outdoor unit air pipe is close to the exhaust temperature in the whole refrigeration process, and the temperature of a refrigerant inlet of an evaporator is lower than the room temperature, so that the exhaust temperature can be used as the temperature of the outdoor unit air pipe, namely, a first temperature sampling value is determined as the target temperature of the outdoor unit air pipe, and the target temperature of the position to be detected can be accurately determined when a second temperature sensor or a third temperature sensor exceeds a temperature acquisition interval.
3. In the embodiment of the invention, when the first temperature sampling value does not exceed the preset temperature threshold, the second temperature sampling value acquired by the second temperature sensor at the refrigerant inlet or the third temperature sampling value acquired by the third temperature sensor at the outdoor unit air pipe can accurately represent the actual temperature value. When the air conditioner is in a heating mode, determining a second temperature sampling value as a target temperature at a refrigerant inlet; when the air conditioner is in a refrigeration mode, the second temperature sampling value is determined as the target temperature of the air pipe of the outdoor unit, and the temperature value acquired by the second temperature sensor or the third temperature sensor at the position to be measured can be guaranteed to accurately represent the target temperature.
4. In the embodiment of the invention, when a first temperature sampling value acquired by the first temperature sensor at the exhaust pipe of the air conditioner is acquired, whether the first temperature sensor is normal or not is judged according to the acquired first temperature sampling value and a preset resistance value temperature corresponding table. If the first temperature sensor is normal, whether the first temperature sampling value exceeds a preset temperature threshold value can be further judged; if the first temperature sensor is abnormal, the first temperature sensor is considered to be in fault, and the first temperature sampling value cannot be used as the exhaust temperature or the target temperature at the position to be measured continuously. Specifically, the resistance value and temperature correspondence table stores the correspondence between the resistance value and the temperature, and when the resistance value corresponding to the first temperature sampling value is within a preset resistance value range, the first temperature sensor is determined to be normal, otherwise, the first temperature sensor is determined to be abnormal. The first temperature sampling value acquired by the first temperature sensor is of great importance in the invention, so that the accuracy of the target temperature at the position to be measured can be ensured when the first temperature sensor is determined to be normal.
5. In the embodiment of the invention, when the first temperature sampling value exceeds the preset temperature threshold value, the temperature at the refrigerant inlet or the air pipe of the outdoor unit is not in the temperature sampling interval of the second temperature sensor or the third temperature sensor, and the second temperature sensor or the third temperature sensor can falsely report that the temperature sensor has a fault when being processed according to the normal temperature. Therefore, the fault signal which is mistakenly reported by the second temperature sensor or the third temperature sensor can be used as a normal signal, and the first temperature sampling value is used as the target temperature at the refrigerant inlet or the air pipe of the outdoor unit.
