Detailed Description
The present invention is described in terms of particular embodiments, other advantages and features of the invention will become apparent to those skilled in the art from the following disclosure, and it is to be understood that the described embodiments are merely exemplary of the invention and that it is not intended to limit the invention to the particular embodiments disclosed. 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.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
The present embodiment provides a control method of an air conditioner, which can be applied to a controller of an air conditioner, referring to a flowchart of the control method of the air conditioner shown in fig. 1, the method mainly includes the following steps S102 to S106:
step S102: and when the air conditioner is detected to be powered on, acquiring current temperature detection values corresponding to input ports of a data processing chip in the indoor unit or the outdoor unit.
Each input port of the data processing chip is connected with a temperature sensing terminal of the temperature sensor. Since the air conditioner usually includes a plurality of sensors, data processing chips may be provided in both the indoor unit and the outdoor unit, each input port of the data processing chip of the indoor unit is connected to a temperature sensing terminal of each temperature sensor in the indoor unit, and each input port of the data processing chip of the outdoor unit is connected to a temperature sensing terminal of each temperature sensor in the outdoor unit.
Each input port of the data processing chip is respectively connected with the temperature sensing terminal of each temperature sensor, and because the specifications of each temperature sensor may be different, each input port is provided with a default parameter comparison table which is related to the specification of the temperature sensor connected with the input port. For example, an indoor unit of an air conditioner is provided with an annular temperature sensor (specification 5K for detecting the ambient temperature) and a tube temperature sensor (specification 20K for detecting the coil temperature), referring to a temperature sensor connection diagram shown in fig. 2, the annular temperature sensor is connected with an annular temperature terminal, the annular temperature terminal is connected with an input port AD1 of a data processing chip, the tube temperature sensor is connected with a tube temperature terminal, and the tube temperature terminal is connected with an input port AD 2.
As shown in fig. 2, in a normal condition, the default parameter lookup table of the input port AD1 is a 5K parameter lookup table (referred to as AD table for short, and the lookup table includes temperature detection values corresponding to the 5K temperature sensors under each temperature sensing resistance value), and the default parameter lookup table of the input port AD2 is a 20K parameter lookup table. After receiving the resistance detection value, the input port AD1 queries a 5K parameter comparison table, and processes the resistance detection value into a temperature detection value of the ring temperature sensor (i.e., a current temperature detection value corresponding to the input port AD 1), so as to obtain an ambient temperature detection value; after the input port AD2 receives the resistance detection value, a 20K parameter comparison table is inquired and processed into a temperature detection value of the pipe temperature sensor (namely, the current temperature detection value corresponding to the input port AD 2), and a coil temperature detection value is obtained.
When the air conditioner is powered on for the first time, the air conditioner is in a non-starting state, and the actual temperature of each temperature detection position in the indoor unit or the outdoor unit is the same; when the air conditioner is started to operate, the temperature values at the temperature detection positions can change, the conditions of comparison at the same temperature are not met, the air conditioner is not judged by mistake, and the actual temperature difference between the coil temperature in the indoor unit and the indoor environment temperature after the air conditioner is started to operate is larger.
Step S104: and judging whether the air conditioner has the misconnection condition of the temperature sensor according to each current temperature detection value.
When the air conditioner is powered on for the first time, the air conditioner is in a non-starting state, the actual temperature of each temperature detection position in the indoor unit or the outdoor unit is at the same level, and whether the current temperature detection values at each position in the indoor unit or the outdoor unit are the same or not is judged, so that whether the sensor misconnection condition exists in the indoor unit or the outdoor unit or not can be accurately judged.
When the air conditioner is powered on for the first time, because the air conditioner does not start to operate, the indoor environment temperature and the outdoor environment temperature may have a difference (that is, the actual temperature of each temperature detection position in the indoor unit is at the same level, and the actual temperature of each temperature detection position in the outdoor unit is at the same level), sensor misconnection judgment needs to be performed on the indoor unit and the outdoor unit respectively, the temperature values detected by the temperature sensors in the indoor unit are theoretically the same, and the temperature values detected by the temperature sensors in the outdoor unit are theoretically the same. When two or more temperature sensors are arranged in the indoor unit, whether the condition that the temperature sensors are in misconnection exists in the indoor unit can be judged according to the current temperature detection values corresponding to the input ports of the data processing chip in the indoor unit. When two or more temperature sensors are arranged in the outdoor unit, whether the condition that the temperature sensors are misconnected exists in the outdoor unit is judged according to the current temperature detection value corresponding to each input port of the data processing chip in the outdoor unit.
Step S106: if yes, the parameter comparison tables corresponding to the input ports are matched again until the difference value of every two current temperature detection values is within the error allowable range.
And interchanging the parameter comparison tables corresponding to the input ports of the data processing chip to re-match the parameter comparison tables of the input ports to re-calculate the temperature detection values corresponding to the input ports until the difference between the temperature detection values corresponding to every two input ports is within an error allowable range, which indicates that the temperature of each temperature detection position is at the same level, thereby realizing automatic error correction and ensuring the normal operation of the air conditioner.
According to the control method of the air conditioner, the current temperature detection values corresponding to the input ports of the data processing chip when the air conditioner is powered on for the first time are obtained, whether the temperature sensor of the air conditioner is in misconnection or not can be automatically detected based on the fact that the temperatures of the temperature detection positions of the air conditioner are the same when the air conditioner is powered on for the first time, when the temperature sensor of the air conditioner is determined to be in misconnection, automatic error correction processing of the air conditioner is achieved by re-matching the parameter comparison table of the input ports of the data processing chip, the accuracy of the temperature detection values is guaranteed, and then normal operation of the air conditioner is guaranteed.
In order to improve the accuracy of automatically detecting whether the temperature sensor is misconnected, the present embodiment provides a specific implementation manner for determining whether the air conditioner has a misconnection condition of the temperature sensor according to each current temperature detection value: and when the temperature difference value of any two current temperature detection values is out of the error allowable range, determining that the air conditioner has the condition of misconnection of the temperature sensor.
The method comprises the steps of obtaining current temperature detection values corresponding to input ports based on a parameter comparison table which is obtained by inquiring resistance detection values received by the input ports of a data processing chip and is defaulted by the input ports, calculating temperature difference values of the current temperature detection values of every two input ports, judging whether the temperature difference values are larger than an error allowable range, and if the temperature difference values of the current temperature detection values of any two input ports are larger than the error allowable range, namely when the air conditioner is electrified for the first time, the temperature difference detected at different positions is larger, so that the temperature sensor is installed abnormally, and a misconnection condition exists.
Referring to the schematic diagram of the misconnection of the temperature sensor shown in fig. 3, when the temperature sensor in fig. 2 is misconnected, that is, the ambient temperature sensor is connected to the tube temperature terminal, the tube temperature sensor is connected to the ambient temperature terminal, the input port AD1 receives the resistance detection value of the tube temperature sensor, the input port AD2 receives the resistance detection value of the ambient temperature sensor, since the default parameter comparison table of the input port AD1 is the 5K parameter comparison table, the default parameter comparison table of the input port AD2 is the 20K parameter comparison table, the specification of the ambient temperature sensor is 5K, and the specification of the tube temperature sensor is 20K. The data processing chip obtains AD1 temperature detection value when receiving the resistance detection value inquiry 5K parameter comparison table of pipe temperature sensor with input port AD1, obtains AD2 temperature detection value when receiving the resistance detection value inquiry 20K parameter comparison table of ring temperature sensor with input port AD2, can judge whether sensor misconnection appears according to the difference between AD1 temperature detection value and AD2 temperature detection value, when the sensor misconnection, because the parameter comparison table of inquiry does not match with the sensor specification, lead to AD1 temperature detection value and AD2 temperature detection value's difference great, can exceed the error allowance range, and then can confirm that there is sensor misconnection.
Referring to the connection diagram of the temperature sensor shown in fig. 2, the ring temperature sensor is connected to the ring temperature terminal, the ring temperature terminal is connected to the input port AD1 of the data processing chip, the tube temperature sensor is connected to the tube temperature terminal, and the tube temperature terminal is connected to the input port AD 2.
As shown in fig. 2, in a normal condition, the default parameter lookup table of the input port AD1 is a 5K parameter lookup table (referred to as AD table for short, and the lookup table includes temperature detection values corresponding to the 5K temperature sensors under each temperature sensing resistance value), and the default parameter lookup table of the input port AD2 is a 20K parameter lookup table. After receiving the resistance detection value, the input port AD1 queries a 5K parameter comparison table, and processes the resistance detection value into a temperature detection value of the ring temperature sensor (i.e., a current temperature detection value corresponding to the input port AD 1), so as to obtain an ambient temperature detection value; after the input port AD2 receives the resistance detection value, a 20K parameter comparison table is inquired and processed into a temperature detection value of the pipe temperature sensor (namely, the current temperature detection value corresponding to the input port AD 2), and a coil temperature detection value is obtained.
When the temperature difference value of any two current temperature detection values in the indoor unit or the outdoor unit is out of the error allowable range, the misconnection of the temperature sensors is judged, whether misconnection exists in each temperature sensor can be automatically and accurately detected, the foolproof cost of air conditioner production is reduced, and the production efficiency of the air conditioner is improved.
In a possible embodiment, the control method of the air conditioner further includes: and when the temperature difference values of the two current temperature detection values are within the error allowable range, determining that the air conditioner does not have the condition of misconnection of the temperature sensors. When the difference between the current temperature detection values corresponding to the two input ports of the data processing chip is within the error range, namely the temperature values detected at the positions when the air conditioner is powered on for the first time are the same or similar, the temperature detection is not abnormal, and the air conditioner does not have the condition of misconnection of the temperature sensors.
When the difference value of every two current temperature detection values is within the error allowable range, the condition that the temperature sensors are not in misconnection is judged, the temperature sensors can be normally connected when the air conditioner is powered on and opened for the first time, the problem that the air conditioner is inaccurate in temperature detection due to the fact that the temperature sensors are abnormally installed is avoided, and the reliability and the stability of the operation of the air conditioner are improved.
In a specific embodiment, the error allowable range is related to the detection precision of the temperature sensor, and the error allowable range is set according to the detection precision of the temperature sensor, so that the rationality of the error allowable range is improved, and the accuracy of the misconnection judgment of the sensor is improved.
In one possible embodiment, the allowable range of the error is [ - (x +0.5x), + (x +0.5x) ], where x is the detection accuracy of the temperature sensor. For example, when the detection accuracy of the temperature sensor is 1 ℃, the error tolerance range is [ -1.5 ℃, +1.5 ℃ ], i.e., when the current temperature difference at the two temperature detection positions is within the range of [ -1.5 ℃, +1.5 ℃ ], it is indicated that the temperature sensor is normally installed. When the detection accuracy of the temperature sensor is 0.5 ℃, the error allowable range is [ -0.75 ℃, +0.75 ℃ ].
Through when temperature sensor detection accuracy is big more, set up great error tolerance, avoid leading to the difference of current temperature to be outside error tolerance because of temperature sensor detection accuracy is great, avoided the erroneous judgement to the sensor misconnection, promoted the detection accuracy that temperature sensor misconnection detected.
In a possible embodiment, if the air conditioner is provided with a first temperature sensor and a second temperature sensor, the first temperature sensor and the second temperature sensor are both located in the indoor unit or the outdoor unit; the first temperature sensor is connected with a first input port of the data processing chip, and the second temperature sensor is connected with a second input port of the data processing chip; the embodiment provides an implementation manner that the parameter comparison tables corresponding to the input ports are re-matched until the difference between every two current temperature detection values is within the error allowable range, and the implementation manner may be specifically executed with reference to the following steps (1) to (3):
step (1): and interchanging a first parameter comparison table corresponding to the first input port and a second parameter comparison table corresponding to the second input port.
Because the outdoor environment temperature is usually higher or lower when using the air conditioner, and the indoor and outdoor environment temperature difference is great, in order to promote the accuracy of sensor misconnection judgment, the temperature detection value of each temperature sensor in the indoor unit or the outdoor unit needs to be judged separately, so as to avoid receiving the influence of the indoor and outdoor environment temperature difference.
And the default parameter comparison table of the first input port of the data processing chip is taken as a first parameter comparison table, the default parameter comparison table of the second input port is taken as a second parameter comparison table, and the parameter comparison tables corresponding to the first input port and the second input port of the data processing chip are interchanged, namely the parameter comparison table corresponding to the first input port is changed into the second parameter comparison table, and the parameter comparison table corresponding to the second input port is changed into the first parameter comparison table.
Taking the data processing chip shown in fig. 3 as an example, the default parameter lookup table of the input port AD1 is a 5K parameter lookup table, the default parameter lookup table of the input port AD2 is a 20K parameter lookup table, and when it is determined that the temperature sensor misconnection exists, the parameter lookup tables of the two input ports are exchanged, that is, the parameter lookup table corresponding to the input port AD1 is changed into the 20K parameter lookup table, and the parameter lookup table corresponding to the input port AD2 is changed into the 5K parameter lookup table.
Step (2): inquiring a second parameter comparison table based on a first resistance detection value received by the first input port to obtain a first temperature detection value corresponding to the first input port; and inquiring the first parameter comparison table based on the second resistance detection value received by the second input port to obtain a second temperature detection value corresponding to the second input port.
And inquiring the exchanged parameter comparison table about the resistance detection values (namely the resistance induction values of the temperature sensors) received by the input ports to obtain new temperature detection values corresponding to the input ports.
Taking the data processing chip shown in fig. 3 as an example, when the input port AD1 receives the resistance detection value, the 20K parameter comparison table is queried to obtain a first temperature detection value, and since the 20K parameter comparison table matches with the specification of the tube temperature sensor, the data processing chip takes the first temperature detection value as the temperature detection value of the tube temperature sensor, that is, the first temperature detection value is the coil temperature. When the input port AD2 receives the resistance detection value, the 2K parameter comparison table is queried to obtain a second temperature detection value, and the 5K parameter comparison table is matched with the specification of the ring temperature sensor, so that the second temperature detection value is used as the temperature detection value of the ring temperature sensor, that is, the second temperature detection value is the ambient temperature.
And (3): and when the difference value of the first temperature detection value and the second temperature detection value is within the error allowable range, determining that the parameter comparison table is successfully matched.
And calculating the temperature difference value between the first temperature detection value and the second temperature detection value, and when the temperature difference value is within the error allowable range, determining that the parameter comparison table of the input port of the data processing chip is successfully matched, namely the parameter comparison table after exchange is used as a new default parameter comparison table.
In a possible implementation manner, if more than two temperature sensors are arranged in the indoor unit or the outdoor unit of the air conditioner, and the parameter comparison tables corresponding to the specifications of the temperature sensors are different; the embodiment provides an implementation method for re-matching the parameter comparison table corresponding to each input port until the difference between every two current temperature detection values is within the error allowable range:
and sequentially exchanging the parameter comparison tables corresponding to any two or more input ports, inquiring the exchanged parameter comparison tables based on the resistance detection values received by the input ports to determine the exchange temperature detection values corresponding to the input ports, and determining that the parameter comparison tables of the input ports are successfully matched until the temperature difference values of every two exchange temperature detection values are within the error allowable range to obtain the correct parameter comparison table corresponding to the input ports.
Because the parameter comparison tables corresponding to the specifications of the temperature sensors are different, the temperature sensors corresponding to the correct parameter comparison tables can be determined according to the correct parameter comparison tables corresponding to the input ports, so that the correct temperature detection values of the temperature sensors can be determined, and the automatic error correction of the temperature detection of the air conditioner is realized.
For example, an indoor unit or an outdoor unit of an air conditioner includes three temperature sensors: the temperature sensor A, the temperature sensor B and the temperature sensor C are sequentially connected with an input port S1, an input port S2 and an input port S3 of the data processing chip, the specifications of the three temperature sensors are sequentially set as y1K, y2K and y3K, an initial default parameter comparison table of the input port S1 is a y1K parameter comparison table, an initial default parameter comparison table of the input port S2 is a y2K parameter comparison table, and an initial default parameter comparison table of the input port S3 is a y3K parameter comparison table.
When the air conditioner is powered on for the first time, based on the current resistance value obtained through the input port S1, inquiring an AD table (namely a parameter comparison table) of y1K to obtain a current temperature P1 corresponding to the input port S1; based on the current resistance value acquired through the input port S2, the AD table of y2K is queried to obtain the current temperature P2 corresponding to the input port S2; based on the current resistance value acquired at the input port S3, the AD table of y3K is queried to obtain the current temperature P3 corresponding to the input port S3.
And if the difference values of every two of the current temperatures P1-P3 are within the error allowable range, determining that the air conditioner is not misconnected by the temperature sensors.
