Fig. 2 is a flowchart illustrating a control method of the air conditioner 100 shown in fig. 1. Fig. 3 is a block diagram showing a component configuration of the control device 400 of the air conditioner 100 shown in fig. 1.
The present invention provides an air conditioner 100, which is an air conditioning apparatus capable of cooling or heating an indoor environment. An air inlet and an air outlet are formed in a casing (not shown) of an indoor unit of the air conditioner 100, a heat exchanger and an air supply fan are arranged in the casing, and air entering the casing from the air inlet exchanges heat with the heat exchanger to form heat exchange airflow which flows into the indoor unit through the air outlet. As shown in fig. 1, the air conditioner 100 is further provided therein with a control device 400, a wireless communication module 200 and a power module 300, wherein the control device 400 communicates with a terminal 500 via the wireless communication module 200, and the power module 300 supplies power to the control device 400 and the wireless communication module 200. As shown in fig. 2, the control method of the air conditioner 100 according to the embodiment of the present invention includes the steps of:
s102: acquiring the network signal strength of the wireless communication module 200;
s104: the data exchange frequency between the wireless communication module 200 and the control device 400 is adjusted according to the network signal strength to reduce the power consumption of the power module 300.
In step S102, the control device 400 obtains the network signal strength of the wireless network in which the wireless communication module 200 is located, and the wireless communication module 200 transmits the network signal strength data to the control device 400. The wireless communication module 200 exchanges data with the control device 400 through a protocol. The wireless communication module 200 performs data exchange with the terminal 500 through a wireless network. The unit of the strength of the network signal strength is dBm, and expressed as a negative number, the closer to 0 the signal is, the better the signal is.
In practical use, the maximum power demand generally occurs only in the rare weak grid environment, resulting in high cost of the power supply system. The control method of the air conditioner 100 according to the embodiment of the present invention is configured to first obtain the network signal strength of the wireless communication module 200, and then adjust the data exchange frequency between the wireless communication module 200 and the control device 400 according to the network signal strength, so that the wireless communication module 200 and the control device 400 do not continuously use the same frequency for data exchange, but are associated with the network signal strength and further adapted to the output capability of the power module 300, and therefore, the power consumption of the power module 300 of the wireless communication module 200 portion can be effectively reduced, and the design cost of the power module 300 can be further reduced.
As shown in fig. 3, the control device 400 of the air conditioner 100 according to the embodiment of the present invention includes a memory 402 and a processor 401, wherein a machine-executable program 420 is stored in the memory 402, and when the machine-executable program 420 is executed by the processor 401, the control device is configured to implement the aforementioned control method of the air conditioner 100.
The power module 300 of the air conditioner 100 according to the embodiment of the present invention may be a switching power supply of the control device 400, that is, the wireless communication module 200 is powered by the switching power supply of the control device 400. The wireless communication module 200 may be selected from an NB-IoT module, a CAT-1 module, a Wi-Fi module, and the like. The aforementioned terminal 500 includes at least one of a remote server, a remote controller, a mobile terminal, and the like.
Fig. 4 is a flowchart illustrating a control method of the air conditioner 100 shown in fig. 1. In some embodiments, the control method of the air conditioner 100 of the embodiment of the present invention includes the steps of:
s202: the network signal strength of the wireless communication module 200 is acquired.
S204: and determining the data exchange frequency corresponding to the network signal strength according to a preset mapping relation, wherein the data exchange frequency corresponding to the network signal strength numerical range is specified in the mapping relation.
S206: the data exchange frequency between the wireless communication module 200 and the control device 400 is adjusted according to the result of step S204.
The control method of the air conditioner 100 according to the embodiment of the present invention, by presetting a mapping relationship, enables the control device 400 to quickly and accurately correspond to the adaptive data exchange frequency after receiving the network signal strength of the wireless communication module 200.
In the mapping relationship, the data exchange frequency decreases as the network signal strength decreases. In the weak network environment, if frequent data exchange is still performed, the power consumption of the power module 300 may be larger, and therefore, in the control method of the air conditioner 100 according to the embodiment of the present invention, the data exchange frequency is reduced along with the reduction of the network signal strength, that is, in the weak network environment, frequent data exchange is not performed any more, so that the power consumption of the power module 300 is reduced.
In the mapping relationship, different network signal strengths may have data exchange frequencies in a one-to-one correspondence, or different ranges of network signal strength values may have different levels of data exchange frequencies. In some embodiments, the mapping relationship of the air conditioner 100 according to the embodiment of the present invention specifies a low network signal strength value range, a medium network signal strength value range, and a high network signal strength value range that are sequentially increased, and the low network signal strength value range, the medium network signal strength value range, and the high network signal strength value range respectively correspond to a slow switching stage, a medium switching stage, and a fast switching stage that are sequentially set according to the magnitude of the data exchange frequency. For example, when the acquired network signal strength is in the low network signal strength numerical range, a slow speed exchange gear is corresponding; and when the acquired network signal intensity is in the high network signal intensity numerical range, a fast exchange gear is correspondingly selected. By defining three ranges of network signal strength values in the mapping relationship and corresponding to three switching steps, it is possible to avoid frequent adjustment of the data exchange frequency between the wireless communication module 200 and the control device 400 due to too fine control.
Fig. 5 is another flowchart illustrating a control method of the air conditioner 100 shown in fig. 1. In other embodiments, a control method of the air conditioner 100 according to an embodiment of the present invention includes the steps of:
s302: the network signal strength of the wireless communication module 200 is acquired.
S304: and judging whether the network signal intensity is smaller than a preset signal intensity threshold value or not. I.e. comparing the network signal strength with a preset signal strength threshold. If the determination result in the step S304 is yes, go to step S306; if the determination result in step S304 is negative, step S308 is executed.
S306: the data exchange frequency is reduced.
S308: the data exchange frequency is kept unchanged.
The control method of the air conditioner 100 according to the embodiment of the present invention compares the network signal strength with the preset signal strength threshold, and reduces the data exchange frequency when the network signal strength is smaller than the preset signal strength threshold, so that the load of the power module 300 in the weak network environment can be effectively reduced by reducing the data exchange frequency. Considering that frequent data exchange mainly in the weak network environment affects the power consumption of the power module 300, when the network signal strength is not less than the preset signal strength threshold, the data exchange frequency is not adjusted, so as to reduce the situation that the data exchange frequency needs to be adjusted.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
