Example one
Fig. 1 is a flowchart of a method for determining temperature field data, which can improve the accuracy of detecting a temperature field according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
s101, acquiring first temperature field data and second temperature field data of an overlapping area of a temperature field detection range of the current air conditioner and a temperature field detection range of a target air conditioner.
In the embodiment of the present invention, the target air conditioners may be air conditioners which have an overlapping area with the current air conditioner within a preset range around the current air conditioner, and the number of the target air conditioners is at least one. Each air conditioner is provided with a temperature field detection device for detecting the temperature field of the corresponding air conditioner, the temperature field detection devices have certain temperature field detection ranges, an overlapping area can exist between the temperature field detection ranges of the adjacent temperature field detection devices, the overlapping area belongs to the edge of the temperature field detection range, and the data accuracy of the detected temperature field is low. For an overlapping area, the temperature field detection device associated therewith will detect the temperature field data of the overlapping area, i.e. the first temperature field data and the second temperature field data. The temperature field sensing means may be a thermopile sensor. The temperature field data detected by the temperature field detection device includes a plurality of temperature data (or called temperature data points), and each position point in the temperature field detection range has corresponding temperature data.
S102, correcting the temperature field data of the overlapping area according to the first temperature field data and the second temperature field data.
In the case of low detection accuracy of the marginal temperature field data, the temperature field data of the overlapping area is corrected by using the two pieces of temperature field data of the same overlapping area, so that the temperature field data with higher accuracy can be obtained.
According to the technical scheme, the temperature field data of the overlapped area are corrected by utilizing the temperature field data, detected by different temperature field detection devices, of the same overlapped area, so that the temperature field data with higher precision are obtained, the detection precision of the marginal temperature field is improved, and the state control of the air conditioner of the courtyard unit is more accurate.
It should be noted that, in the embodiment of the present invention, a plurality of target air conditioners may be involved, and for each target air conditioner, the temperature field data is updated according to the method described above. Preferably, after the temperature field detection function is started, the system can identify all air conditioners in the area where the system is located, and sequence each air conditioner to obtain a corresponding serial number. In the process of correcting and updating the temperature field data, the data of the temperature field in the corresponding overlapping area can be updated according to the sequence of the sequence numbers. For example, 10 air conditioners in total are updated by correcting the temperature field data from the air conditioner a according to the serial number, the target air conditioners around the air conditioner a are B and C, the temperature field data of the air conditioners a and B are updated first, and then the temperature field data of the air conditioners a and C are updated. Taking the air conditioner B as an example, the overlapping area of the temperature field detection ranges of the air conditioners a and B is a, specifically, the temperature field data m of the overlapping area a detected by the temperature field detection device of the air conditioner a and the temperature field data n of the overlapping area a detected by the temperature field detection device of the air conditioner B are acquired, and the temperature field data of the overlapping area a is corrected according to the temperature field data m and n. Of course, if the processing speed meets the requirement, the data of the temperature field in the overlapped area of a plurality of pairs of air conditioners can be updated at the same time.
Optionally, S101 may include: acquiring a target air conditioner within a preset range around the current air conditioner; determining an overlapping area of a temperature field detection range of the current air conditioner and a temperature field detection range of a target air conditioner; taking the temperature field data of the overlapping area detected by the temperature field detection device of the current air conditioner as first temperature field data; and using the temperature field data of the overlapping area detected by the temperature field detection device of the target air conditioner as second temperature field data. The air conditioner may be provided with a position detection device for detecting the position information of the air conditioner within a preset range around the air conditioner, where the preset range may be a detection range of the position detection device.
The embodiment acquires the target air conditioner to determine the overlapping area of the temperature field detection ranges between the air conditioners, acquires the temperature field data of the overlapping area detected by different temperature field detection devices, and has a simple and reliable data acquisition mode.
Further, determining an overlapping area of the temperature field detection range of the current air conditioner and the temperature field detection range of the target air conditioner includes: acquiring position information of a target air conditioner; determining the distance between the temperature field detection device of the current air conditioner and the temperature field detection device of the target air conditioner according to the position information; and determining the overlapping area of the temperature field detection range of the current air conditioner and the temperature field detection range of the target air conditioner according to the distance.
After the temperature field detection device of the current air conditioner detects the temperature field information of the corresponding area along the fixed track, the air conditioner located in the temperature field detection range of the current air conditioner can be identified according to the preset working radius, the target air conditioner and the position information of the target air conditioner are determined, and then the overlapping area between the temperature field detection ranges can be determined. After the overlap region is thus determined, the temperature field data can be adjusted with precision.
Optionally, S102 may include: calculating a temperature reference value of the overlapping area according to the first temperature field data and the second temperature field data; and if the temperature reference value is in the preset error interval, respectively calculating the average value of the temperature data at the same position in the first temperature field data and the second temperature field data, and taking the average value as the temperature value of the position.
The temperature reference value may reflect the fluctuation size of the first temperature field data and the second temperature field data. If the temperature reference value is in the preset error interval, the fluctuation is acceptable, and the temperature field data can be corrected. And aiming at each position point in the temperature field, calculating the temperature mean value of the position point by using the first temperature field data and the second temperature field data to serve as the final temperature value of the position point, and by analogy, updating the temperature value of each position point one by one, thereby finishing the updating of the temperature field data. The preset error interval may be set according to the detection accuracy of the temperature field detection device, for example, the preset error interval is set to 0.01 to 0.05, if the temperature reference value is not in the preset error interval, the temperature field data may be erroneously obtained, the overlap area may be determined again, if the temperature reference values for multiple times are not in the preset error interval, the preset error interval may be set unreasonably, and the error interval may be retested and set.
The optional embodiment is simple to calculate and can obtain accurate temperature field data.
Optionally, before calculating the mean of the temperature data at the same position in the first temperature field data and the second temperature field data, the method may further include: calculating a first average value of all temperature data in the first temperature field data, and eliminating error data points in the first temperature field data according to the first average value; and calculating a second average value of all temperature data in the second temperature field data, and rejecting error data points in the second temperature field data according to the second average value. For example, a data point that is greatly different from the average value may be rejected as an erroneous data point.
The optional embodiment eliminates data points with large errors, so that the precision of the temperature field data can be further improved.
Optionally, calculating a temperature reference value of the overlap region according to the first temperature field data and the second temperature field data, including: respectively calculating the difference value of the temperature data at the same position in the first temperature field data and the second temperature field data; the average of all differences is calculated as the temperature reference. The method is simple in calculation, and the data fluctuation can be reflected by taking the average value of the difference values of the two data sets as the temperature reference value.
Preferably, before calculating the difference between the temperature data at the same position in the first temperature field data and the temperature data at the same position in the second temperature field data, the method may further include: data merging is carried out on the first temperature field data according to a preset rule, and merged first data are obtained; and merging the data of the second temperature field according to a preset rule to obtain merged second data. Subsequently, respectively calculating the difference value of the temperature data at the same position in the first data and the second data; the average of all differences is calculated as the temperature reference.
For example, the preset rule may be to combine a preset number of temperature data into one data point, and use the average value of the preset number of temperature data as the combined temperature value. Therefore, the number of temperature data points can be reduced, the calculation amount is further reduced, and the processing speed is improved.
Optionally, if the temperature reference value is greater than the preset threshold, the temperature field detection device of the current air conditioner and the temperature field detection device of the target air conditioner are controlled to rotate by a preset angle in the preset direction, and the steps of determining the overlapping area, obtaining the first temperature field data and the second temperature field data of the overlapping area, and calculating the temperature reference value of the overlapping area are executed again until the temperature field detection device rotates to the maximum offset angle or the temperature reference value is within the preset error interval.
The preset threshold is a value greater than the maximum value of the preset error interval, for example, the preset error interval is 0.01-0.05, the preset threshold is 0.1, if the temperature reference value is greater than the preset threshold, it indicates that the difference between the first temperature field data and the second temperature field data is too large, the overlapping area needs to be readjusted, a new temperature reference value is obtained according to the above steps, and the relationship between the temperature reference value and the preset threshold, and the preset error interval is re-determined. The preset direction may be a connection direction of the two temperature field detection devices, and the specific adjustment direction is to enlarge the overlapping area. The preset angle can adopt a default value or can be customized by a user.
The embodiment can reduce the difference between the temperature field data of the same overlapping area, so that the corrected temperature field data has higher precision. If the temperature field data have certain difference, the whole precision optimization process can be reflected by the opposite movement of the two temperature field detection devices, and when a plurality of air conditioners act simultaneously, which two machine types are being adjusted can be seen from the sequential movement of the temperature field detection devices.
In another embodiment, after S102, the method may further include: and transmitting the corrected temperature field data to the target air conditioner. The target air conditioner can update the data of the corresponding area according to the corrected temperature field data to obtain the temperature field data with higher precision, so that the state control of the air conditioner is more accurate.
Optionally, after transmitting the corrected temperature field data to the target air conditioner, the method may further include: and setting the temperature field data updating completion identification of the current air conditioner and the target air conditioner. Therefore, when the target air conditioner is used as the current air conditioner for updating, the temperature field data updating completion identifier is read, so that the target air conditioner and which air conditioners have been subjected to temperature field data updating can be known, repeated updating is not needed, and time waste and occupation of computing resources are avoided.
Generally, in practical applications, the distance between the air conditioners is set, and a situation that three air conditioners form an overlapping area at the same time rarely occurs, but the embodiment of the present invention may also be applied to such a situation, for example, the temperature field data is updated for a small overlapping area formed by three air conditioners, and the specific implementation is similar to the above method, and is not described again. The areas of the three air conditioners are overlapped, and the three air conditioners can be basically separated into two air conditioner areas which are overlapped, so that the data can be updated according to the two overlapping by using the method.
It should be noted that a period of precision adjustment may be defined, for example, the temperature field data of the overlapping region is updated once when 10 complete temperature fields are detected.
Example two
Fig. 2 is a specific flowchart of a temperature field data determining method capable of improving the detection accuracy of a temperature field according to a second embodiment of the present invention, as shown in fig. 2, the method includes:
when the user uses the integrated controller to start the temperature field detection function, the system identifies all the air conditioners in the area, and sequences each air conditioner.
After the thermopile sensor of the air conditioner A detects the temperature field information of the area along a fixed track, according to the position information of the nearby air conditioners returned by the position detection device, the air conditioner in the working radius area of the temperature field detection device of the air conditioner A is identified through the preset working radius of the temperature field detection device, the temperature field overlapping area with other air conditioners (B, C, D … …) is determined, and the overlapping area between the temperature field detection ranges is calculated.
After the air conditioner a reads the area temperature field by using the temperature field detection device and obtains the overlapping area temperature field data of the target air conditioner B, the two temperature field data of the overlapping area are subjected to data processing, specifically, according to the length and width values of the obtained overlapping area, the temperature field data are combined into a data point according to four temperature data by a calculation method (specifically, an average value is calculated), and the temperature data are combined, so that the data volume is reduced. And if the data does not meet the requirement of combining the four temperature points, combining the rest temperature point data directly according to the calculation method. And then, performing difference processing on the temperature field data point after the combination of the air conditioner A and the temperature field data point after the combination of the target air conditioner B, specifically, calculating the difference value of two data at the same position, and then calculating the mean value of all the difference values, wherein the mean value is the average of the difference values of the temperature fields of two observation same places, and can reflect the fluctuation value of the two data. If the value is larger than the preset threshold value, the difference between the two temperature field data is too large.
And the temperature field detection devices expand the detection range, namely expand the overlapping area according to the judgment result, specifically, the two temperature field detection devices are deviated by a preset angle (such as 5 degrees) along the direction of the connecting line of the two temperature field detection devices, the fluctuation data of the temperature difference value of the current repetition region are continuously detected, and if the obtained fluctuation data exceeds a preset threshold value, the deviation angles of the two temperature field detection devices are continuously adjusted until the temperature field detection devices can reach the maximum deviation angle. When the fluctuation data meets the preset error interval, the following processing is carried out on the two pieces of temperature field data: firstly, respectively calculating the average temperature data of two temperature field data, eliminating error data points with large difference, respectively calculating the average value of the data points of each position according to the one-to-one correspondence of the two temperature field data according to the positions, and updating the temperature field data of an overlapped area according to the average value. And sharing the updated overlapped area temperature field data to the target air conditioner so that the target air conditioner updates the temperature field data thereof.
Specifically, after the update of the overlapping temperature field of the air conditioner a is completed, the overlapping temperature field of the air conditioner (B, C, D … …) may be updated according to the sequence of the sequence numbers.
When the update operation of the overlap area temperature field between the air conditioners a and B is completed, the update completion flag between the air conditioners a and B may be added to avoid the repetition of the update operation.
