Description
技术领域technical field
本发明涉及空调技术领域，具体地，涉及一种室内机通讯地址的配置方法、空调系统及空调室内机。The present invention relates to the technical field of air conditioning, in particular to a method for configuring communication addresses of indoor units, an air conditioning system and an air conditioning indoor unit.
背景技术Background technique
在一个多联机系统中外机通常可连接多台不同的内机。内机数量最多可达到128台。为保证内外机的通讯正常，每台内机都必须有一个唯一且与其它内机不重复的通讯地址。这些内机所处的区域和安装方式不同，如果采用手动设定地址将给售后的安装调试及维修都带来不便。In a multi-connected system, the outdoor unit can usually be connected to multiple different indoor units. The maximum number of internal units can reach 128. In order to ensure normal communication between the internal and external units, each internal unit must have a unique communication address that is not repeated with other internal units. The areas and installation methods of these indoor units are different. If the address is manually set, it will bring inconvenience to the installation, commissioning and maintenance after sales.
目前各厂家在自动实现设定内机通讯地址时通常采用硬件固化地址和通过软件由外机设定实现。采用硬件固化地址实现时，每个内机出厂前电脑板芯片都有唯一的地址编号，能够实现售后安装时地址不会冲突。通过软件由外机设定实现时，需要外机检测内机地址，发竞争指令给内机，内机接收指令后才能自动改变地址。At present, when manufacturers automatically set the communication address of the internal machine, they usually use hardware to fix the address and set it by the external machine through software. When the hardware fixed address is used to realize, each computer board chip of the internal unit has a unique address number before leaving the factory, so that the addresses will not conflict during after-sales installation. When the software is set by the external machine, it is necessary for the external machine to detect the address of the internal machine and send a competition command to the internal machine, and the internal machine can automatically change the address after receiving the command.
采用硬件固化地址实现时，电脑板需要增加一个特殊的地址识别芯片，硬件成本会增加。而通过软件由外机设定实现时，需要外机主导内机地址自动设定过程。这期间需要内外机的多次反复确认，增加了软件设计难度和复杂度，且用时过长。When implementing hardware-fixed addresses, a special address recognition chip needs to be added to the computer board, and the hardware cost will increase. However, when the software is set by the external machine, the external machine needs to lead the process of automatically setting the address of the internal machine. During this period, multiple confirmations of internal and external machines are required, which increases the difficulty and complexity of software design and takes too long.
针对相关技术中外机主导内机地址的设定过程中需要内外机多次反复确认、以及需要借助额外硬件芯片的问题，目前尚未提出有效的解决方案。Aiming at the problems in the related technology that the external machine dominates the address setting of the internal machine, which requires multiple confirmations of the internal and external machines and the need for additional hardware chips, no effective solution has been proposed so far.

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，所描述的实施例仅仅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所获得的所有其他实施例，都属于本发明保护的范围。The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention belong to the protection scope of the present invention.
根据本发明的实施例，提供了一种室内机通讯地址的配置方法，使多个室内机在至少一个周期内进行通讯地址的竞争。According to an embodiment of the present invention, a method for configuring communication addresses of indoor units is provided, so that multiple indoor units compete for communication addresses within at least one cycle.
如图1所示，根据本发明实施例的室内机通讯地址的配置方法包括：As shown in Figure 1, the method for configuring the communication address of the indoor unit according to the embodiment of the present invention includes:
步骤S101，在每个周期内，每个室内机发送竞争数据帧，并且每个室内机监听其他室内机发送的竞争数据帧，其中，对于每个室内机，该室内机发送的竞争数据帧中携带有该室内机需要竞争的通讯地址；Step S101, in each cycle, each indoor unit sends a contention data frame, and each indoor unit monitors the contention data frames sent by other indoor units, wherein, for each indoor unit, in the contention data frame sent by the indoor unit Carry the communication address that the indoor unit needs to compete for;
步骤S103，在每个周期内，对于每个室内机，根据本周期内该室内机和其他室内机发送的竞争数据帧中需要竞争的通讯地址判断该室内机是否在本周期内竞争该通讯地址成功，如果在本周期内竞争成功，该室内机在下一周期内发送的竞争数据帧中携带该竞争成功的通讯地址，否则该室内机在下一周期内发送携带其他需要竞争的通讯地址的竞争数据帧；Step S103, in each period, for each indoor unit, judge whether the indoor unit competes for the communication address in the current period according to the communication address that needs to be competed in the competition data frame sent by the indoor unit and other indoor units in the current period Success, if the competition is successful in this period, the indoor unit will send the competition data frame in the next period to carry the successful communication address, otherwise the indoor unit will send competition data with other communication addresses that need to be competed in the next period frame;
步骤S105，对于每个室内机，将该室内机成功竞争到通讯地址配置为该室内机的通讯地址。Step S105, for each indoor unit, configure the communication address to which the indoor unit successfully competes as the communication address of the indoor unit.
其中，在每个周期内，每个室内机发送的竞争数据帧进一步包括随机数，并且，在一个周期内一室内机判断该室内机在本周期内需要竞争的通讯地址是否与其他室内机需要竞争的通讯地址发生冲突；Wherein, in each period, the competition data frame sent by each indoor unit further includes random numbers, and in one period, an indoor unit judges whether the communication address that the indoor unit needs to compete for in this period is the same as that required by other indoor units. Conflict between competing mailing addresses;
并且，竞争的地址发生冲突的室内机在下一周期内竞争与本周期相同的通讯地址，并在发送的竞争数据帧中携带重新选择的随机数。Moreover, the indoor units whose competing addresses collide compete for the same communication address as this cycle in the next cycle, and carry the re-selected random number in the contention data frame sent.
在一个周期内，一室内机判断该室内机在本周期内需要竞争的通讯地址是否与其他室内机需要竞争的通讯地址发生冲突的条件可以是：该室内机与其他室内机中的至少一个室内机需要竞争的通讯地址和随机数分别对应相同(即，两个或两个以上室内机发送的数据帧中携带的通讯地址彼此相同，并且这些室内机发送的数据帧中携带的随机数彼此相同)。In one period, the condition for an indoor unit to determine whether the communication address that the indoor unit needs to compete for in this period conflicts with the communication addresses that other indoor units need to compete for can be: the indoor unit and at least one indoor unit among other indoor units The communication addresses and random numbers that the units need to compete for are the same (that is, the communication addresses carried in the data frames sent by two or more indoor units are the same as each other, and the random numbers carried in the data frames sent by these indoor units are the same as each other) ).
此外，在多个室内机需要竞争的通讯地址相同、而发送的竞争数据帧中的随机数不同的情况下，每个室内机都将其与该多个室内机中其他室内机发送的随机数进行比较，根据预定规则以及比较结果确定竞争该通讯地址成功的室内机。其中，预定规则可以是将发送竞争数据帧中携带的随机数较小的室内机作为竞争成功的室内机。当然，也可以是将发送竞争数据帧中携带的随机数较大的室内机作为竞争成功的室内机。In addition, when multiple indoor units need to compete for the same communication address, but the random numbers in the contention data frames sent are different, each indoor unit compares it with the random number sent by other indoor units among the multiple indoor units. The comparison is performed, and the indoor unit that successfully competes for the communication address is determined according to the predetermined rule and the comparison result. Wherein, the predetermined rule may be that the indoor unit that sends the smaller random number carried in the contention data frame is regarded as the indoor unit that succeeds in the competition. Of course, the indoor unit that sends the larger random number carried in the competition data frame may also be used as the indoor unit that succeeds in the competition.
此外，如果该室内机需要竞争的通讯地址与其他室内机需要竞争的通讯地址不同，也可以判断该室内机在本周期内竞争成功。In addition, if the communication address that the indoor unit needs to compete for is different from the communication addresses that other indoor units need to compete for, it can also be judged that the indoor unit competes successfully in this period.
也就是说，由于每个室内机都能够知道其他室内机发送的竞争数据帧，也就能够知道本室内机与其他室内机对通讯地址的竞争是否成功和/或是否竞争发生冲突。That is to say, since each indoor unit can know the contention data frames sent by other indoor units, it can also know whether the competition between the indoor unit and other indoor units for the communication address is successful and/or whether there is a conflict in the competition.
其中，对于每个室内机，如果该室内机在预定数量的周期内连续竞争同一通讯地址成功，则确定该室内机竞争到该通讯地址，且该室内机将多个周期内竞争成功的该通讯地址配置为该室内机的通讯地址。Wherein, for each indoor unit, if the indoor unit successfully competes for the same communication address within a predetermined number of cycles, it is determined that the indoor unit has competed for the communication address, and the indoor unit will successfully compete for the communication address within a plurality of cycles. The address is configured as the communication address of the indoor unit.
如果一室内机在一个周期内竞争一个通讯地址失败，该室内机在下一周期内需要竞争其他通讯地址，并且在下一周期内发送的竞争数据帧中携带不同于本周期竞争的通讯地址。在选择下一周期需要竞争的通讯地址时，可以按照地址从小到大的顺序来选择，当然也可以按照其他顺序或某个特定策略来选择。If an indoor unit fails to compete for a communication address in one cycle, the indoor unit needs to compete for other communication addresses in the next cycle, and the contention data frame sent in the next cycle carries a different communication address than the competition in this cycle. When selecting the communication addresses that need to compete in the next cycle, the addresses can be selected in ascending order of addresses, and of course can also be selected in accordance with other orders or a specific strategy.
在本发明的方案中，多个室内机竞争通讯地址的过程是周期性进行的，并且，多个室内机可以根据定时而自发发起竞争，也可以响应于来自室外机的外机数据帧发送竞争数据帧，其中，室外机会周期性地向多个室内机发送外机数据帧。In the solution of the present invention, the process of multiple indoor units competing for the communication address is carried out periodically, and multiple indoor units can initiate competition spontaneously according to the timing, and can also send contention in response to the data frame from the outdoor unit. data frame, wherein the outdoor unit periodically sends data frames of the outdoor unit to multiple indoor units.
如图2所示，空调室内机上的电芯片初始化后，接收来自外机发送的外机数据帧，例如OU FR(该数据帧的发送的时间点可以参照图3，且该数据帧中可以包括压力、频率等室外机需要定期通知给多个室内机的参数)。然后室内机发送地址自动竞争标识数据帧，例如AUTO_FR(发送的时间点可以参照图3)。室内机以当前存在电可擦写可编程只读存储器(Electrically Erasable Programmable Read-Only Memory，简称为EEPROM)芯片中的地址依次发送数据，例如IN1 FR～INn FR。室内机在发送完自己的数据后，可同时监听总线上其它室内机中的数据。根据室内机数据帧中包含的通讯地址，可以判断室内机通讯地址是否有冲突。所有室内机发送完数据帧后，室内外机结束本轮通讯。As shown in Figure 2, after the electric chip on the indoor unit of the air conditioner is initialized, it receives an external unit data frame sent from the external unit, such as OU FR (the time point of sending the data frame can refer to Figure 3, and the data frame can include Parameters such as pressure, frequency, etc. that the outdoor unit needs to regularly notify multiple indoor units). Then the indoor unit sends an address automatic contention identification data frame, such as AUTO_FR (for the sending time point, refer to Figure 3). The indoor unit sends data sequentially using addresses currently stored in an Electrically Erasable Programmable Read-Only Memory (EEPROM for short) chip, such as IN1 FR˜INn FR. After sending its own data, the indoor unit can monitor the data of other indoor units on the bus at the same time. According to the communication address contained in the data frame of the indoor unit, it can be judged whether the communication address of the indoor unit conflicts. After all indoor units send data frames, the indoor and outdoor units end the current round of communication.
在下一轮通讯中，室外机继续向室内机发送外机数据帧，例如OU FR。室内机在上一轮通讯中如果检测到有室内机地址冲突，会继续发送室内机地址自动竞争标识数据帧，例如AUTO_FR。在所有室内机中，没有地址冲突的室内机继续使用当前的地址发送数据，而地址冲突的室内机依次竞争使用总线上没有被确认的剩余通讯地址(地址按从小到大排列，例如：0、1、2......)，发送室内机数据帧。在此轮通讯结束后，下一轮通讯会继续判断。如果没有发生地址冲突，则室内外机进入正常通讯阶段。连续N次(例如，N可以为3次、4次、5次或更多次，可根据具体情况进行设定)无室内机地址冲突且竞争成功时，室内机当前使用的地址会写到自己的EEPROM芯片中，进行地址保存。In the next round of communication, the outdoor unit continues to send outdoor unit data frames, such as OU FR, to the indoor unit. If the indoor unit detects an indoor unit address conflict in the last round of communication, it will continue to send the indoor unit address automatic competition identification data frame, such as AUTO_FR. Among all indoor units, the indoor units without address conflict continue to use the current address to send data, while the indoor units with address conflict compete to use the remaining communication addresses on the bus that have not been confirmed in turn (addresses are arranged in ascending order, for example: 0, 1, 2...), send indoor unit data frame. After this round of communication ends, the next round of communication will continue to judge. If there is no address conflict, the indoor and outdoor units enter the normal communication stage. When there is no indoor unit address conflict and the competition is successful for N consecutive times (for example, N can be 3, 4, 5 or more times, which can be set according to specific conditions), the address currently used by the indoor unit will be written to its own In the EEPROM chip, the address is saved.
