Description
本发明属于空调技术领域,具体提供一种基于功率调整改善空调内外机无线通信质量的方法和***。The invention belongs to the technical field of air conditioners, and specifically provides a method and system for improving the wireless communication quality of internal and external units of an air conditioner based on power adjustment.
目前的空调***中,内机和外机之间的数据、控制信号的传输主要采用强电通信、HomeBus通信、RS485通信等有线方式。这些方式需要安装大量的通信线材,不仅硬件成本高,且需要耗费人力安装。相较于有线通信方式,无线通信方式中,只需在内机和外机中分别安装无线通信模块,通过无线连接来实现数据、控制指令的传输交换,因不采用线缆,能够省去布线的繁琐和成本,且安装结构能够更简洁更美观。In the current air conditioning system, the transmission of data and control signals between the indoor unit and the outdoor unit mainly adopts wired methods such as strong current communication, HomeBus communication, and RS485 communication. These methods require the installation of a large number of communication cables, which not only requires high hardware costs, but also requires labor-intensive installation. Compared with the wired communication method, in the wireless communication method, it is only necessary to install wireless communication modules in the internal unit and the external unit, and realize the transmission and exchange of data and control commands through wireless connection. Since no cables are used, wiring can be omitted. It is cumbersome and costly, and the installation structure can be simpler and more beautiful.
空调室外机和室内机之间的无线连接通信,目前量产化的方式是要为Zigbee。Zigbee过去又称为“HomeRFLite”和“FireFly”技术,现在统一称为Zigbee技术,主要用于距离短、功耗低且传输速率不高的各种电子设备之间进行数据传输以及典型的有周期性数据、间歇性数据和低反应时间数据传输的应用。以多联机空调为例,室外机和室内机之间可以取消通信线,直接采用Zigbee模块进行数据传递,大大提高安装效率、降低人工成本。Zigbee模块必然涉及组网问题,业内通用的做法是,Zigbee模块一旦组网完成后,PADID/频道等信息参数就固定下来,不再允许变更,目的是防止组网出现混乱,同时通信模块的发射功率都是固定的, 如果按照标准上限设计,会造成机组的耗电功耗增加,不利于节能减排,因此Zigbee模块出厂后,发射功率参数一般不再调整。The wireless connection communication between the outdoor unit and the indoor unit of the air conditioner is currently mass-produced by Zigbee. Zigbee, also known as "HomeRFLite" and "FireFly" technology in the past, is now collectively called Zigbee technology. It is mainly used for data transmission between various electronic devices with short distance, low power consumption and low transmission rate, as well as typical periodic Applications for intermittent data, intermittent data, and low latency data transfer. Taking the multi-connected air conditioner as an example, the communication line between the outdoor unit and the indoor unit can be eliminated, and the Zigbee module can be directly used for data transmission, which greatly improves the installation efficiency and reduces labor costs. The Zigbee module must involve networking issues. The common practice in the industry is that once the Zigbee module is networked, the PADID/channel and other information parameters are fixed and no longer allowed to be changed. The power is fixed. If it is designed according to the standard upper limit, the power consumption of the unit will increase, which is not conducive to energy saving and emission reduction. Therefore, after the Zigbee module leaves the factory, the transmit power parameters are generally not adjusted.
Zigbee通信采用的是2.4G频段,但是,随着智能化家居的推广,使用2.4G频段的用户越来越多,可能出现Wifi用户占用Zigbee信道的问题。现有的Zigbee组网模块,一旦组网完成,频道不允许变更,如果出现Wifi占用信道的问题,无法自动解决,唯一的方法是重新组网。但是,这种方法在多联机空调机组上不太适用,因为这样涉及售后人员重新对机组进行调试和组网验证,容易造成用户的抱怨。Zigbee communication uses the 2.4G frequency band. However, with the promotion of smart homes, more and more users use the 2.4G frequency band, and there may be a problem that Wifi users occupy the Zigbee channel. The existing Zigbee networking module, once the networking is completed, the channel is not allowed to change, if there is a problem of Wifi occupying the channel, it cannot be solved automatically, the only way is to re-network. However, this method is not suitable for multi-connected air-conditioning units, because it involves after-sales personnel re-commissioning and networking verification of the unit, which is likely to cause complaints from users.
作为示例,中国专利申请CN106322662A公开了一种空调内外机无线通信***和通信方法,该空调***包括空调内外机,每部空调内机包括内机无线通信模块和内机故障处理模块,空调外机包括外机无线通信模块、外机故障处理模块和组网切换信道模块;外机故障处理模块在接收到通信故障通报后,控制外机无线通信模块清空其自身的EEPROM中的空调运行数据;内机故障处理模块在内机无线通信模块没有收到外机通信模块发送的数据后,控制与其相连的内机无线通信模块清空其自身的EEPROM中的空调运行数据;组网切换信道模块则针对所述空调外机和同***内所有空调内机组建信道。由此可见,在CN106322662A的方案中,空调外机在接收到通信故障通报后,控制其外机无线通信模块清空其自身的EEPROM中的运行数据,使得同***内所有内机的无线通信模块在第一设定时间内无法收到外机无线通信模块发送的数据后,控制清空其自身的EEPROM中的空调运行数据,然后针对空调外机和同***内所有空调内机重新组建信道。也就是说,CN106322662A的方案也是在发生通信故障之后进行重新组网,该方案虽然无需售后人员人工操作,但重新组网仍然会影响用户的使用体验。As an example, Chinese patent application CN106322662A discloses a wireless communication system and communication method for internal and external units of an air conditioner. The air-conditioning system includes internal and external units of an air conditioner, and each internal unit of an air conditioner includes an internal unit wireless communication module and an internal unit fault handling module. It includes an external unit wireless communication module, an external unit fault processing module and a network switching channel module; the external unit fault processing module controls the external unit wireless communication module to clear the air conditioner operation data in its own EEPROM after receiving the communication fault notification; After the fault handling module of the internal unit does not receive the data sent by the communication module of the external unit, it controls the wireless communication module of the internal unit connected to it to clear the air conditioner operation data in its own EEPROM; The outdoor unit of the air conditioner and all the indoor units of the air conditioner in the same system form a channel. It can be seen that in the solution of CN106322662A, after receiving the communication failure notification, the air conditioner outdoor unit controls the wireless communication module of the outdoor unit to clear the running data in its own EEPROM, so that the wireless communication modules of all the indoor units in the same system are in the same system. After the data sent by the wireless communication module of the external unit cannot be received within the first set time, control to clear the air conditioner operation data in its own EEPROM, and then re-establish the channel for the air conditioner external unit and all the air conditioner internal units in the same system. That is to say, the solution of CN106322662A also re-networks after a communication failure occurs. Although this solution does not require manual operation by after-sales personnel, the re-networking will still affect the user experience.
因此,本领域需要一种新的方法来解决上述问题。Therefore, there is a need in the art for a new method to solve the above problems.

为使本发明实施例的目的、技术方案和优点更加清楚,下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。In order to make the purposes, 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 accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments These are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
下面参照附图来描述本发明的优选实施方式。本领域技术人员应当理解的是,这些实施方式仅仅用于解释本发明的技术原理,并非旨在限制本发明的保护范围。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 used to explain the technical principle of the present invention, and are not intended to limit the protection scope of the present invention.
首先参阅图1,图1是本发明的基于功率调整改善空调内外机无线通信质量的方法的主要步骤流程图。如图1所示,本发明的基于功率调整 改善空调内外机无线通信质量的方法包括下列步骤:S1,检测室外机与室内机的通信误码率;S2,将检测到的通信误码率与设定阈值进行比较;S3,当检测到的通信误码率大于所述设定阈值时,所述室内机调整其无线通信模块的信号发射功率,直至所述通信误码率小于所述设定阈值。Referring first to FIG. 1 , FIG. 1 is a flow chart of the main steps of the method for improving the wireless communication quality of internal and external units of an air conditioner based on power adjustment of the present invention. As shown in FIG. 1, the method for improving the wireless communication quality of the indoor and outdoor units of the air conditioner based on the power adjustment of the present invention includes the following steps: S1, detecting the communication bit error rate between the outdoor unit and the indoor unit; S2, comparing the detected communication bit error rate with the Set a threshold for comparison; S3, when the detected communication bit error rate is greater than the set threshold, the indoor unit adjusts the signal transmission power of its wireless communication module until the communication bit error rate is less than the set threshold.
优选地,当检测到的通信误码率大于所述设定阈值时,所述室内机提高其无线通信模块的信号发射功率,直至所述通信误码率小于所述设定阈值。更优选地,当检测到的通信误码率大于所述设定阈值时,所述室内机分阶段多次提高其无线通信模块的信号发射功率,直至所述通信误码率小于所述设定阈值。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 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 multiple times in stages until the communication error rate is less than the set threshold. threshold.
上述步骤S1中对室外机与室内机的通信误码率的检测可以采用各种不同的方式进行,这些方式都是本领域公知的,这里不再赘述。作为示例,可以由室外机统计其与室内机之间的通信错误次数,并在此基础上计算相应的通信误码率。The detection of the communication bit error rate between the outdoor unit and the indoor unit in the above step S1 may be performed in various ways, which are well known in the art, and will not be repeated here. As an example, the number of communication errors between the outdoor unit and the indoor unit may be counted, and the corresponding communication bit error rate may be calculated on this basis.
在上述步骤S2中,所述设定阈值可以由技术人员根据机型和应用场景设定,其大小以能够准确反映信道被占用为准,尽量避免将常规的无线信号波动认定为信道占用。作为示例,所述设定阈值可以在50%-80%的范围内取值。In the above-mentioned step S2, the set threshold can be set by technicians according to the model and application scenario, and its size can accurately reflect the occupied channel, and try to avoid identifying the regular wireless signal fluctuation as the channel occupied. As an example, the set threshold may take a value in the range of 50%-80%.
需要说明的是,在实践中,上述步骤S1和S2通常都在室外机端执行,即,所述设定阈值存储在室外机上,室外机统计其与室内机通信错误的频率并将该数值与所述设定阈值进行比较。当然,这并不是限制性的,在改变本发明的原理的前提下,上述步骤S1和S2也可以由其他主体来执行。例如,在物联网空调的情形中,所述设定阈值可以存储在云端服务器上,步骤S2可以由云端服务器来执行。这种对执行主体的调整并没有改变本发明的原理,因此也将落入本发明的保护范围之内。It should be noted that, in practice, the above steps S1 and S2 are usually performed on the outdoor unit side, that is, the set threshold is stored on the outdoor unit, and the outdoor unit counts the frequency of communication errors between the outdoor unit and the indoor unit and compares the value with the value. The set thresholds are compared. Of course, this is not limitative, and on the premise of changing the principle of the present invention, the above steps S1 and S2 can also be performed by other subjects. 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. This adjustment to the executive body does not change the principle of the present invention, and therefore will also fall within the protection scope of the present invention.
接着分析步骤S3,当检测到的通信误码率大于所述设定阈值时,表明当前室内机与室外机的无线通信信道被占用,此时室外机或云端服务 器向室内机下发通知,命令其提高自身无线通信模块的信号发射功率。如上文中描述的,为了在尽可能降低功耗,室内机在收到命令之后并不是一下就将无线通信模块的信号发射功率提到很高,而是采用分阶段、多次、小幅度提升的方式,在此过程中室外机会实时检测和判断当前通信误码率与所述设定阈值之间的关系,一旦发现当前通信误码率低于所述设定阈值时,室外机或云端服务器就通知室内机通知提高信号发射功率,从而在保证通信质量的前提下最大程度地降低功耗。Then analyze step S3, when the detected communication bit error rate is greater than the set threshold, it indicates that the current wireless communication channel between the indoor unit and the outdoor unit is occupied, and the outdoor unit or the cloud server sends a notification to the indoor unit, commanding It improves the signal transmission power of its own wireless communication module. As described above, in order to reduce power consumption as much as possible, the indoor unit does not immediately raise the signal transmission power of the wireless communication module to a high level after receiving the command, but adopts a step-by-step, multiple, and small-scale increase. In this process, the outdoor unit detects and judges the relationship between the current communication bit error rate and the set threshold in real time. Once it is found that the current communication bit error rate is lower than the set threshold, the outdoor unit or the cloud server will Notify the indoor unit to increase the signal transmission power, so as to minimize the power consumption on the premise of ensuring the communication quality.
下面结合基于Zigbee通信的多联机并参阅图2来描述本发明的方法在室外机侧的具体操作。具体地,本发明的多联机包括一台室外机和多台室内机,所述室外机和每台室内机上均设置有无线通信模块。图1中“检测室外机与室内机的通信误码率”的步骤在多联机的情形下具体包括:检测所述室外机上的无线通信模块与每一台室内机上的无线通信模块之间的通信误码率。此外,上述室外机和室内机上的无线通信模块都是Zigbee模块。The specific operation of the method of the present invention on the outdoor unit side will be described below in conjunction with the multi-connection based on Zigbee communication and referring to FIG. 2 . Specifically, the multi-connection of the present invention includes one outdoor unit and multiple indoor units, and a wireless communication module is provided on the outdoor unit and each indoor unit. The step of “detecting the communication bit error rate between the outdoor unit and the indoor unit” in FIG. 1 specifically includes in the case of multiple connections: detecting the communication between the wireless communication module on the outdoor unit and the wireless communication module on each indoor unit bit error rate. In addition, the wireless communication modules on the above-mentioned outdoor unit and indoor unit are all Zigbee modules.
需要说明的是,尽管这里描述的多联机仅包括一台室外机,但是,这并不是限制性的,本发明的技术方案可以应用于包括多台室外机的多联机空调。当应用于包括多台室外机的多联机空调时,所述室外机上的无线通信模块可以特指其中一台室外机上的无线通信模块,也可以泛指任意一台室外机上的无线通信模块,只要其能够执行误码率检测以及将检测到的误码率与设定阈值进行比较的操作即可。此外,尽管这里描述的无线通信方式是Zigbee,这也不是限制性的,在不改变本发明的原理的情况下,本领域技术人员也可以根据需要将其应用于其他无线通信空调中,这种对无线通信方式的改变并不偏离本发明的基本原理,因此也将落入本发明的保护范围之内。It should be noted that although the multi-line air conditioner described here only includes one outdoor unit, this is not limitative, and the technical solution of the present invention can be applied to a multi-line air conditioner including multiple outdoor units. When applied to a multi-connected air conditioner including multiple outdoor units, the wireless communication module on the outdoor unit may specifically refer to the wireless communication module on one of the outdoor units, or may refer to the wireless communication module on any outdoor unit in general, as long as It suffices to be able to perform bit error rate detection and to compare the detected bit error rate with a set threshold. In addition, although the wireless communication method described here is Zigbee, this is not limitative. Those skilled in the art can also apply it to other wireless communication air conditioners as required without changing the principle of the present invention. Changes to the wireless communication method do not deviate from the basic principles of the present invention, and therefore fall within the protection scope of the present invention.
如图2所示,首先多联机机组上电,接下来室外机跟室内机上的Zigbee模块彼此组网。这里的组网方式可以是已知的任何无线组网方式, 此除不再详细描述。接下来,室外机判断检测到通信误码率是否高于设定阈值(N%)以及这种状态的持续时间是否超过预设时间T1,如果没有,则室外机跟室内机上的Zigbee模块在当前信道下继续通信。如果答案为是,则室外机判断是哪个室内机的通信误码率高于设定阈值(N%)且持续时间超过了预设时间T1,接下来室外机给对应的室内机发送通知,命令其提高Zigbee模块的信号发射功率,然后室外机再判断是否所有对应的室内机都应答了该通知,如果是的话,室外机在T2时间之后重新开始误码率统计,并同时开始计时,然后判断是否收到对应室内机调整完功率的应答,如果是的话,则本轮通信误码率调整结束。如果答案是否,则室外机重新给没有应答的室内机发送功率调整通知,如果在T3时间之后依然没有收到某个或某些室内机的应答,则室外机会反复发送通信质量差的通知,请对应室内机进行发射功率的调整。如果所有误码率超限的室内机都调整了信号发射功率并且当前没有检测到任何误码率超限的室内机,则本轮通信误码率调整结束。As shown in Figure 2, the multi-connected units are powered on first, and then the Zigbee modules on the outdoor unit and the indoor unit are networked with each other. The networking mode here can be any known wireless networking mode, which will not be described in detail. Next, the outdoor unit determines whether the detected communication bit error rate is higher than the set threshold (N%) and whether the duration of this state exceeds the preset time T1. If not, the Zigbee module on the outdoor unit and the indoor unit are currently continue to communicate over the channel. If the answer is yes, the outdoor unit determines which indoor unit has a communication error rate higher than the set threshold (N%) and the duration exceeds the preset time T1, and then the outdoor unit sends a notification to the corresponding indoor unit, commanding It increases the signal transmission power of the Zigbee module, and then the outdoor unit determines whether all the corresponding indoor units have responded to the notification. If so, the outdoor unit restarts the bit error rate statistics after T2 time, and starts timing at the same time, and then judges Whether it receives the response that the corresponding indoor unit has adjusted the power, if so, the current round of communication bit error rate adjustment ends. If the answer is no, the outdoor unit will re-send the power adjustment notification to the indoor unit that has not responded. If it still does not receive a response from one or some indoor units after T3 time, the outdoor unit will repeatedly send a notification of poor communication quality. Adjust the transmit power corresponding to the indoor unit. If all indoor units whose BER exceeds the limit have adjusted the signal transmission power and no indoor unit with BER exceeding the limit is detected, the current round of communication BER adjustment ends.
下面结合图3来描述本发明的方法在室内机侧的具体操作。在图3的示例中,假设室内机的无线通信模块的发射功率可以在三个不同档位上进行调整。具体地,如图3所示,在收到室外机发送的误码率过高的通知之后,室内机先判断其无线通信模块的发射功率是否在最低档位(X1档位),如果判断结果为是,则将无线通信模块的发射功率调整至二级档位(X2档位)并应答给室外机,告知发射功率调整完毕。如果判断结果为否,则进一步判断其无线通信模块的发射功率是否在二级档位(X2档位),如果判断结果为是,则将无线通信模块的发射功率调整至更高的三级档位(X3档位)并应答给室外机,告知发射功率调整完毕。如果判断结果为否,则证明无线通信模块的发射功率本身就在最高档位,此时直接应答给室外机,告知发射功率调整完毕。The specific operation of the method of the present invention on the indoor unit side will be described below with reference to FIG. 3 . In the example of FIG. 3 , it is assumed that the transmit power of the wireless communication module of the indoor unit can be adjusted in three different gears. Specifically, as shown in Figure 3, after receiving the notification that the bit error rate is too high sent by the outdoor unit, the indoor unit first judges whether the transmit power of its wireless communication module is at the lowest gear (X1 gear), and if the result of the judgment is If yes, adjust the transmission power of the wireless communication module to the second-level gear (X2 gear) and reply to the outdoor unit to inform that the adjustment of the transmission power is completed. If the judgment result is no, it is further judged whether the transmission power of the wireless communication module is in the second-level gear (X2 gear), and if the judgment result is yes, the transmission power of the wireless communication module is adjusted to a higher third-level gear position (X3 position) and reply to the outdoor unit to inform the transmission power adjustment is completed. If the judgment result is no, it proves that the transmission power of the wireless communication module itself is at the highest level. At this time, it directly responds to the outdoor unit to inform that the transmission power adjustment is completed.
本发明的另一个方面还提供了一种基于功率调整改善空调内外机无线通信质量的***,所述***包括检测模块、比较模块和通信质量优化模块,其中,检测模块用于检测室外机与室内机的通信误码率;比较模块用于将所述通信误码率与设定阈值进行比较;通信质量优化模块用于在所述通信误码率大于所述设定阈值时,命令所述室内机调整其无线通信模块的信号发射功率,直至所述通信误码率小于所述设定阈值。具体地,所述通信质量优化模块命令所述室内机提高其无线通信模块的信号发射功率,直至所述通信误码率小于所述设定阈值。更具体地,所述通信质量优化模块命令所述室内机分阶段多次提高其无线通信模块的信号发射功率,以便在保证通信质量的前提下最大程度地降低功耗。Another aspect of the present invention also provides a system for improving wireless communication quality between indoor and outdoor units of an air conditioner based on power adjustment. The system includes a detection module, a comparison module and a communication quality optimization module, wherein the detection module is used to detect the connection between the outdoor unit and the indoor unit. The comparison module is used to compare the communication bit error rate with a set threshold value; the communication quality optimization module is used to order the indoor communication bit error rate when the communication bit error rate is greater than the set threshold value The computer adjusts the signal transmission power of its wireless communication module until the communication bit error rate is less than the set threshold. Specifically, the communication quality optimization module instructs the indoor unit to increase the signal transmission power of its wireless communication module until the communication bit error rate is less than the set threshold. More specifically, the communication quality optimization module instructs the indoor unit to increase the signal transmission power of its wireless communication module multiple times in stages, so as to minimize power consumption on the premise of ensuring communication quality.
关于上述***,需要说明的是,其中的模块只是为了更清楚地解释本发明的技术方案而虚拟出来的功能模块,这些模块跟实际应用中的物理器件并非严格对应。如上面结合图1描述的,在实际应用中,误码率检测和比较的操作通常由室外机或云端服务器执行,在这种情况下室外机或云端服务器就对应于上述检测模块和比较模块。此外,如果功率调整的命令由室外机的无线通信模块发送,则室外机的无线通信模块就对应于上述通信质量优化模块。这种虚拟模块与物理器件之间对应关系的变化并不偏离本发明的基本原理,因此,在这些方面作出调整的技术方案也将落入本发明的保护范围之内。Regarding the above system, it should be noted that the modules therein are just virtual function modules for explaining the technical solutions of the present invention more clearly, and these modules do not strictly correspond to physical devices in practical applications. As described above in conjunction with FIG. 1 , in practical applications, the operations of bit error rate detection and comparison are usually performed by an outdoor unit or a cloud server. In this case, the outdoor unit or cloud server corresponds to the above detection module and comparison module. In addition, if the command for power adjustment is sent by the wireless communication module of the outdoor unit, the wireless communication module of the outdoor unit corresponds to the above-mentioned communication quality optimization module. The change of the corresponding relationship between the virtual module and the physical device does not deviate from the basic principle of the present invention. Therefore, the technical solutions for making adjustments in these aspects will also fall within the protection scope of the present invention.
