Background Art

[0004] With the rapid development of society and the economy, various household appliances are becoming increasingly common in people's daily lives. However, in relatively underdeveloped and remote areas, power grid instability persists, leading to frequent power outages. To address this issue, non-mains power sources, such as community generators or small household generators, are often used to compensate for mains outages. This means that when the mains power goes out, the power source is switched to the non-mains power source. However, non-mains power sources like community generators or small household generators have limited capacity and cannot guarantee full operation of all household appliances. Therefore, it is important to prioritize appliances that are urgently needed, such as lighting and televisions. Air conditioners require manual operation using a remote control to reduce energy consumption and ensure stable operation. However, inappropriate remote control operation, or during sleep, can cause the air conditioner to be current-limited, causing the device to shut down or rendering other appliances unusable, impacting operational stability. Therefore, finding a more timely and effective automatic control solution for air conditioner operation based on power source switching has become an urgent challenge.

[0041] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0042] It should be noted that the terms "first", "second", etc. in the specification of the present application and the above-mentioned drawings are used to distinguish similar users and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0043] The following is a detailed description of an embodiment of the air conditioner operation mode control method based on power supply switching described in this application. As shown in Figure 1, it is a flow chart of the air conditioner operation mode control method based on power supply switching provided by this application. The specific implementation process includes the following steps.

[0044] Step 101: A preset signal transmitting module collects a power supply signal from a non-mains power source, modulates the power supply signal to obtain a target modulated signal to be transmitted, and transmits the target modulated signal to a preset signal receiving module. The non-mains power source is connected to an air conditioner via a power supply line, and the non-mains power source is used to provide power to the air conditioner. The signal transmitting module is connected to the power supply line and is used to collect the power supply signal from the non-mains power source. The air conditioner may include multiple indoor units and corresponding multiple outdoor units.

[0045] During the implementation of this step, it is first necessary to detect whether the mains power supply connected to the air conditioner is in a power-off state. When the mains power supply is in a power-off state, it is necessary to detect whether the power supply of the air conditioner is switched to a non-mains power supply. If so, the signal transmitting module is used to collect the power supply signal transmitted by the non-mains power supply to the air conditioner. Specifically, if the preset signal transmitting module can collect the power supply signal transmitted by the non-mains power supply, it is determined that the mains power supply connected to the air conditioner is in a power-off state. If the preset signal transmitting module does not collect the power supply signal transmitted by the non-mains power supply, it is determined that the mains power supply connected to the air conditioner is in a power-on state. The signal transmitting module used in this application includes at least one signal transmitting module, and its installation form is a three-pin plug form. The acquisition module for collecting the power supply signal can be installed inside the box of the signal transmitting module, and is used to be powered by the non-mains power supply to ensure its signal transmission.

[0046] As shown in FIG2 , in one embodiment, a preset power conversion device (i.e., an electrically controlled adapter box placed outdoors) may also be included. This power conversion device has an input and an output. The input power comes from various power sources, such as a mains power source, a community generator, a personal generator, etc., connected via power supply lines. The output power is connected to a household power outlet. In addition, a mains power source is directly connected to a household mains outlet for use by non-essential electrical appliances. The input and output of the signal transmission module are respectively connected to the neutral wire (N line) and the live wire (L line) of the power supply line between the non-mains power source and the input of the power conversion device. The non-mains power source includes, but is not limited to, a community generator, a personal generator, etc. It should be noted that the present application may include multiple indoor units, such as indoor unit 1 ... indoor unit N, where N is an integer greater than 1. Each indoor unit corresponds to an outdoor unit. Each indoor unit is also connected to a signal receiving module. The power supply line of the signal receiving module is connected to the L line and N line of the indoor unit's power supply line. A signal transmission line dedicated to non-transmitted signals is established between the signal receiving module and the indoor unit.

[0047] In the process of transmitting the target modulated signal to the preset signal receiving module, the target modulated signal can be transmitted to the preset signal receiving module by using power line carrier communication between the signal transmitting module and the signal receiving module. Specifically, the energy-saving control of the air conditioner using the power line carrier principle, i.e., power line carrier communication (PLC), refers to a special communication method that uses high-voltage power lines, medium-voltage power lines, or low-voltage distribution lines as information transmission media for voice or data transmission. During transmission, the collected data is modulated using modulation technology, and the information-carrying modulated signal is loaded onto the current, which is then transmitted over the inherent power line. At the receiving end, the modulated signal is first filtered out and then demodulated to obtain the original communication signal, which is then transmitted to a computer or phone to achieve information transmission. In addition, the target modulated signal can also be transmitted to the preset signal receiving module by using a preset wireless communication network between the signal transmitting module and the signal receiving module. Therefore, before sending the target modulated signal to the preset signal receiving module, it is necessary to pre-establish a wireless communication network between the signal transmitting module and the signal receiving module using wireless signal transmission technology, which includes but is not limited to Wifi, NB-IOT, LoRa, ZigBee, etc. for signal transmission and delivery. The signal transmitting module transmits the signal, and the signal receiving module receives the signal. The signal can be transmitted between the two via a wireless communication network, which can achieve multi-node control, wide coverage, low power consumption, and minimal impact from power grid operation fluctuations. It avoids signal transmission distortion caused by voltage fluctuations and can achieve signal transmission independent of power grid operation conditions.

[0048] Step 102: Based on the signal receiving module, the target modulated signal is obtained, and the target modulated signal is demodulated to obtain the original power supply signal; based on the original power supply signal, the indoor unit of the air conditioner is triggered to enter a preset energy-saving working mode; wherein, the power supply circuit of the signal receiving module is connected to the power supply of the indoor unit of the air conditioner; the signal receiving module is connected to the indoor unit of the air conditioner via a signal transmission circuit, and the signal receiving module is used to send the control instruction of the energy-saving working mode to the indoor unit of the air conditioner via the signal transmission circuit.

[0049] The signal receiving module is installed next to the indoor unit or built into it. Its power supply comes from the indoor unit's power supply, and a dedicated signal line (i.e., signal transmission line) is provided to connect the signal receiving module and the indoor unit's computer motherboard to ensure signal transmission. The air conditioner's power supply comes from a regular indoor power outlet to ensure its continuous operation. The signal transmitting module can be plugged into an indoor non-mains power outlet. The number of signal receiving modules is the same as the number of indoor units, and each signal receiving module corresponds to one indoor unit. In other words, the number of signal receiving modules is not limited to one. Depending on the number of indoor units installed in the home, the number of signal receiving modules is equivalent to the number of indoor units. There can be only one signal transmitting module or multiple signal transmitting modules, thereby realizing a control method for a multi-terminal energy-saving mode. The following combinations are all within the scope of protection of this application: 1 signal transmitting module → N signal receiving modules; N signal transmitting modules → N signal receiving modules; N signal transmitting modules → 1 signal receiving module; where N can be a positive integer of 1, 2, 3, ... n.

[0050] In the process of triggering the control of the indoor unit of the air conditioner to enter the preset energy-saving working mode based on the original power supply signal, the corresponding specific implementation process includes: generating the corresponding control instructions of the energy-saving working mode based on the original power supply signal, and sending the control instructions of the energy-saving working mode to the computer motherboard of the indoor unit of the air conditioner based on the signal transmission line, so as to trigger the control of the indoor unit of the air conditioner to enter the preset energy-saving working mode. Among them, the signal transmission line is a signal transmission line that connects the signal receiving module and the computer motherboard of the indoor unit of the air conditioner and is used to transmit specific signals. Therefore, before generating the corresponding control instructions of the energy-saving working mode based on the original power supply signal, it is necessary to pre-establish a signal transmission line between the signal receiving module and the computer motherboard of the indoor unit of the air conditioner.

[0051] After triggering the control of the indoor unit of the air conditioner to enter a preset energy-saving operating mode based on the original power supply signal, the actual power supply capacity corresponding to the non-mains power supply can also be obtained, and the air conditioner can be adjusted to a corresponding operating gear according to the actual power supply capacity. For example, a correspondence between different power supply capacities and air conditioner operating gears can be pre-established. During implementation, the air conditioner can be adjusted to the corresponding operating gear based on the detected actual power supply capacity and the correspondence.

[0052] When the mains power is operating normally and other power sources are unavailable, the signal transmitter module, connected to a non-mains power source, is not powered. Communication between the signal transmitter module and the signal receiver module (i.e., the signal receiver module) is lost, and the air conditioner operates according to user settings. When the mains power is disconnected, another power source (i.e., non-mains power) supplies power to the home, and the non-mains power outlet becomes powered, communication between the signal transmitter module and the signal receiver module is normal, indicating that another power source (i.e., non-mains power) is supplying power to the home. The signal receiver module controls the indoor unit's computer motherboard to enter the appropriate energy-saving mode to ensure that other electrical appliances can operate within its limited power capacity.

[0053] The air conditioner operation mode control method based on power supply switching provided in the present application collects the power supply signal of the non-mains power supply through the signal transmitting module and performs modulation processing to obtain the target modulation signal to be transmitted, and sends the target modulation signal to the signal receiving module; obtains the target modulation signal based on the signal receiving module, and demodulates the target modulation signal to obtain the original power supply signal, and triggers the entry into the energy-saving working mode based on the original power supply signal; the signal receiving module is connected to the indoor unit of the air conditioner through a signal transmission line, and the signal receiving module is used to send the control instruction of the energy-saving working mode to the indoor unit of the air conditioner through the signal transmission line, and can automatically control the air conditioner to enter the power-saving mode according to the detection of whether the mains power supply is available, and adjust the operating gear of the air conditioner according to the power supply capacity, to ensure that the air conditioner operates at maximum load when other electrical appliances are in normal use, to ensure the stability of the air conditioner operation when the power supply is switched, to effectively reduce the power consumption, and thus to improve the user experience.
