Description
Technical Field
The invention belongs to the technical field of air conditioners, and particularly provides a method and a system for improving the wireless communication quality of an internal machine and an external machine of an air conditioner based on power adjustment.
Background
In the current air conditioning system, the transmission of data and control signals between an internal unit and an external unit mainly adopts wired modes such as strong electric communication, HomeBus communication, RS485 communication and the like. These methods require a large number of communication wires to be installed, which not only results in high hardware cost, but also requires labor-intensive installation. Compared with a wired communication mode, in a wireless communication mode, only the wireless communication modules are respectively installed in the inner unit and the outer unit, transmission and exchange of data and control instructions are achieved through wireless connection, complexity and cost of wiring can be saved due to the fact that cables are not adopted, and the installation structure can be simpler and more attractive.
The wireless connection communication between the outdoor unit and the indoor unit of the air conditioner is currently implemented in a mass production mode, namely Zigbee. The Zigbee technology, which is also called "HomeRF Lite" and "FireFly" technology in the past, is now collectively called Zigbee technology, and is mainly used for data transmission between various electronic devices with short distance, low power consumption, and low transmission rate, and typically, for applications with periodic data, intermittent data, and low-latency data transmission. Taking a multi-split air conditioner as an example, a communication line can be omitted between the outdoor unit and the indoor unit, and a Zigbee module is directly adopted for data transmission, so that the installation efficiency is greatly improved, and the labor cost is reduced. The Zigbee module inevitably relates to the networking problem, and the method in the industry is generally used, once the networking of the Zigbee module is completed, information parameters such as PADID/channel and the like are fixed, and are not allowed to be changed any more, so that the networking is prevented from being disordered, meanwhile, the transmission power of the communication module is fixed, if the Zigbee module is designed according to the standard upper limit, the power consumption and the power consumption of a unit are increased, the energy conservation and the emission reduction are not facilitated, and therefore, the transmission power parameters are not generally adjusted any more after the Zigbee module leaves a.
The 2.4G frequency band is adopted for Zigbee communication, but as intelligent home is popularized, more and more users use the 2.4G frequency band, and the problem that Wifi users occupy a Zigbee channel may occur. In the existing Zigbee networking module, once networking is completed, a frequency channel is not allowed to be changed, and if the problem that Wifi occupies the channel occurs, the problem cannot be automatically solved, and the only method is to perform networking again. However, this method is not suitable for the multi-split air conditioning unit, because it involves the after-sales personnel to debug and perform networking verification on the unit again, which is easy to cause complaints of users.
As an example, chinese patent application CN106322662A discloses an air conditioner indoor and outdoor unit wireless communication system and a communication method, the air conditioner system includes an air conditioner indoor unit and an air conditioner outdoor unit, each air conditioner indoor unit includes an indoor unit wireless communication module and an indoor unit fault processing module, the air conditioner outdoor unit includes an outdoor unit wireless communication module, an outdoor unit fault processing module and a networking switching channel module; after receiving the communication fault report, the external machine fault processing module controls the external machine wireless communication module to empty the air conditioner operation data in the EEPROM of the external machine wireless communication module; the internal machine fault processing module controls the internal machine wireless communication module connected with the internal machine fault processing module to empty the air conditioner operation data in the EEPROM of the internal machine fault processing module after the internal machine wireless communication module does not receive the data sent by the external machine communication module; and the networking switching channel module is used for establishing channels aiming at the air conditioner external unit and all air conditioner internal units in the same system. Therefore, in the scheme of CN106322662A, after receiving the communication failure report, the air conditioner external unit controls its external unit wireless communication module to clear the operating data in its own EEPROM, so that after the wireless communication modules of all internal units in the same system cannot receive the data sent by the external unit wireless communication module within the first set time, the air conditioner external unit controls to clear the air conditioner operating data in its own EEPROM, and then re-establishes channels for the air conditioner external unit and all air conditioner internal units in the same system. That is, the CN106322662A solution is also to perform re-networking after a communication failure, and although the solution does not need manual operation by after-sales personnel, the re-networking still affects the user experience.
Therefore, there is a need in the art for a new method to solve the above problems.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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 some, but not all, embodiments of the present invention. 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.
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.
Referring first to fig. 1, fig. 1 is a flow chart illustrating the main steps of a method for improving the wireless communication quality of an indoor unit and an outdoor unit of an air conditioner based on power adjustment according to the present invention. As shown in fig. 1, the method for improving the wireless communication quality of the indoor unit and the outdoor unit of the air conditioner based on power adjustment of the present invention comprises the following steps: s1, detecting the communication error rate of the outdoor unit and the indoor unit; s2, comparing the detected communication error rate with a set threshold value; and S3, when the detected communication error rate is greater than the set threshold, the indoor unit adjusts the signal transmission power of the wireless communication module of the indoor unit until the communication error rate is less than the set threshold.
Preferably, when the detected communication error rate is greater than the set threshold, the indoor unit increases the signal transmission power of the wireless communication module of the indoor unit until the communication error rate is less than the set threshold. More preferably, when the detected communication error rate is greater than the set threshold, the indoor unit increases the signal transmission power of its wireless communication module by stages for multiple times until the communication error rate is less than the set threshold.
The detection of the communication error rate between the outdoor unit and the indoor unit in step S1 can be performed in various ways, which are well known in the art and will not be described herein. As an example, the outdoor unit may count the number of communication errors between the outdoor unit and the indoor unit, and calculate the corresponding communication error rate based on the counted number.
In step S2, the setting threshold may be set by a technician according to the model and the application scenario, and the size of the setting threshold is determined to accurately reflect the occupied channel, so as to avoid identifying the regular wireless signal fluctuation as the occupied channel as much as possible. As an example, the set threshold may be a value in a range of 50% -80%.
It should be noted that, in practice, the above steps S1 and S2 are usually performed at the outdoor unit end, that is, the set threshold is stored in the outdoor unit, and the outdoor unit counts the frequency of communication errors between the outdoor unit and the indoor unit and compares the count with the set threshold. Of course, this is not restrictive, and the above steps S1 and S2 may be performed by other subjects as well, with the principle of the present invention being changed. For example, in the case of an internet-of-things air conditioner, the set threshold may be stored on a cloud server, and step S2 may be performed by the cloud server. Such adjustments to the implementation body do not alter the principles of the present invention and therefore would fall within the scope of the present invention.
And analyzing step S3, when the detected communication error rate is greater than the set threshold, indicating that the wireless communication channels of the current indoor unit and the current outdoor unit are occupied, and at this time, the outdoor unit or the cloud server issues a notification to the indoor unit to command the indoor unit to increase the signal transmission power of its wireless communication module. As described above, in order to reduce the power consumption as much as possible, the indoor unit does not raise the signal transmission power of the wireless communication module to be high immediately after receiving the command, but adopts a staged, multiple, and small-amplitude raising manner, during which the outdoor unit may detect and judge the relationship between the current communication error rate and the set threshold in real time, and once the current communication error rate is found to be lower than the set threshold, the outdoor unit or the cloud server notifies the indoor unit to raise the signal transmission power, thereby reducing the power consumption to the maximum extent on the premise of ensuring the communication quality.
The specific operation of the method of the present invention on the outdoor unit side is described below with reference to fig. 2 in conjunction with multiple online systems based on Zigbee communication. Specifically, the multi-split air conditioner comprises an outdoor unit and a plurality of indoor units, wherein the outdoor unit and each indoor unit are respectively provided with a wireless communication module. In fig. 1, "detecting the error rate of communication between the outdoor unit and the indoor unit" specifically includes, in the case of multiple on-line systems: and detecting the communication error rate between the wireless communication module on the outdoor unit and the wireless communication module on each indoor unit. In addition, the wireless communication modules on the outdoor unit and the indoor unit are Zigbee modules.
It should be noted that, although the multi-split air conditioner described herein includes only one outdoor unit, this is not a limitation, and the technical solution of the present invention may be applied to a multi-split air conditioner including a plurality of outdoor units. When the method is applied to a multi-split air conditioner comprising a plurality of outdoor units, the wireless communication module on the outdoor unit may refer to a wireless communication module on one of the outdoor units, or may refer to a wireless communication module on any one of the outdoor units in general, as long as the method can perform the operations of detecting the error rate and comparing the detected error rate with a set threshold. In addition, although the wireless communication method described herein is Zigbee, this is not limiting, and those skilled in the art can apply it to other wireless communication air conditioners as needed without changing the principle of the present invention, and such changes to the wireless communication method do not depart from the basic principle of the present invention, and therefore, will also fall within the protection scope of the present invention.
As shown in fig. 2, the multi-split air conditioner set is powered on, and then the outdoor unit and the Zigbee modules on the indoor unit are networked with each other. The networking method may be any known wireless networking method, and is not described in detail herein. Next, the outdoor unit determines whether the detected communication error rate is higher than a set threshold (N%) and whether the duration of this state exceeds a preset time T1, and if not, the outdoor unit continues to communicate with the Zigbee module on the indoor unit under the current channel. If the answer is yes, the outdoor unit judges which indoor unit has the communication error rate higher than the set threshold (N%) and the duration time exceeds the preset time T1, then the outdoor unit sends a notification to the corresponding indoor unit to command the indoor unit to improve the signal transmission power of the Zigbee module, then the outdoor unit judges whether all the corresponding indoor units respond to the notification, if so, the outdoor unit restarts error rate statistics after the time T2 and starts timing at the same time, then whether the response that the corresponding indoor units have adjusted the power is received, and if so, the communication error rate adjustment is finished in the current round. If the answer is no, the outdoor unit sends a power adjustment notice to the indoor units without response again, and if the response of one or some indoor units is still not received after the time T3, the outdoor unit may repeatedly send a notice of poor communication quality to please adjust the transmission power of the corresponding indoor unit. And if all the indoor units with the error rate exceeding the limit have adjusted the signal transmission power and any indoor unit with the error rate exceeding the limit is not detected currently, the error rate adjustment of the communication in the current round is finished.
The specific operation of the method of the present invention on the indoor machine side is described below with reference to fig. 3. In the example of fig. 3, it is assumed that the transmission power of the wireless communication module of the indoor unit can be adjusted in three different gears. Specifically, as shown in fig. 3, after receiving the notification of the excessive error rate sent by the outdoor unit, the indoor unit first determines whether the transmission power of the wireless communication module is in the lowest gear (X1 gear), and if so, adjusts the transmission power of the wireless communication module to the second-level gear (X2 gear) and responds to the outdoor unit to notify that the transmission power adjustment is completed. If the judgment result is negative, whether the transmitting power of the wireless communication module is in a secondary gear (X2 gear) is further judged, and if the judgment result is positive, the transmitting power of the wireless communication module is adjusted to a higher tertiary gear (X3 gear) and responded to the outdoor unit, and the completion of the adjustment of the transmitting power is informed. If the judgment result is negative, the transmission power of the wireless communication module is proved to be in the highest gear, and at the moment, the wireless communication module directly responds to the outdoor unit to inform that the transmission power is adjusted.
The invention also provides a system for improving the wireless communication quality of the indoor unit and the outdoor unit of the air conditioner based on power adjustment, which comprises a detection module, a comparison module and a communication quality optimization module, wherein the detection module is used for detecting the communication error rate of the outdoor unit and the indoor unit; the comparison module is used for comparing the communication error rate with a set threshold value; and the communication quality optimization module is used for commanding the indoor unit to adjust the signal transmitting power of the wireless communication module of the indoor unit when the communication error rate is greater than the set threshold value until the communication error rate is less than the set threshold value. Specifically, the communication quality optimization module commands the indoor unit to increase the signal transmission power of the wireless communication module of the indoor unit until the communication error rate is smaller than the set threshold. More specifically, the communication quality optimization module commands the indoor unit to increase the signal transmission power of the wireless communication module of the indoor unit for multiple times in stages, so as to reduce power consumption to the maximum extent on the premise of ensuring the communication quality.
With regard to the above system, it should be noted that the modules are only the functional modules virtualized for clearly explaining the technical solution of the present invention, and the modules do not strictly correspond to the physical devices in the practical application. As described above with reference to fig. 1, in practical applications, the error rate detection and comparison operations are usually performed by the outdoor unit or the cloud server, in which case the outdoor unit or the cloud server corresponds to the detection module and the comparison module. In addition, if the command for power adjustment is transmitted by the wireless communication module of the outdoor unit, the wireless communication module of the outdoor unit corresponds to the communication quality optimizing module. Such changes in the correspondence between the virtual modules and the physical devices do not depart from the basic principle of the present invention, and therefore, the technical solutions adjusted in these aspects will also fall within the protection scope of the present invention.

Whether such functionality is implemented as electronic hardware or software depends upon the particular application and design constraints imposed on the solution. Skilled artisans may implement the described functionality in varying ways for each particular application, but such implementation decisions should not be interpreted as causing a departure from the scope of the present invention.
