[0051] It should be understood that the above general description and the following detailed description are only exemplary and explanatory, and cannot limit the present disclosure. Brief Description of the Drawings

[0052] The drawings herein are incorporated into the specification and constitute a part of this specification, showing embodiments consistent with the present disclosure, and are used together with the specification to explain the principles of the present disclosure.

[0053] Figure 1 is a flowchart of a method for signal processing shown according to an exemplary embodiment.

[0054] Figure 2 is a flowchart of another method for signal processing shown according to an exemplary embodiment.

[0055] Figure 3 is a block diagram of a device for signal processing shown according to an exemplary embodiment.

[0056] Figure 4 is a block diagram of an electronic device shown according to an exemplary embodiment.

[0057] Figure 5 is a block diagram of another electronic device shown according to an exemplary embodiment. Detailed Description of the Embodiments

[0058] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are only examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0059] First, the application scenario of the present disclosure is introduced. The present disclosure is applied to the scenario of verifying infrared signals. The infrared signal can be composed of one or more of a header code, a data code, and an end code. Each infrared signal can include a header code and multiple data codes; in the case of serial transmission of multiple infrared signals, the serial signal can include multiple end codes. Among them, each header code or data code can be composed of a low level and a high level.

[0060] In the related art, when an infrared signal is received, it is necessary to verify the high and low levels of the infrared signal to verify the accuracy of the infrared signal, so as to complete the control transmission of the signal. However, since the verification standards for the head code and the data code are relatively close, it is easy to have inaccurate verification problems during the verification of the head code or the data code.

[0061] Moreover, the ambient temperature will also affect the accuracy of the infrared signal verification result, reducing the work efficiency. For example, when the ambient temperature of the environment where the infrared signal receiving device is located is too low, the accuracy of the verification result is low. Therefore, in order to reduce the influence of the ambient temperature on the accuracy of the verification result, higher requirements are put forward for the performance of the infrared signal receiving device, resulting in too high production costs of the receiving device.

[0062] To solve the above problems, the present disclosure provides a signal processing method, device, electronic device and storage medium; by obtaining an infrared signal emitted by a target control device; the target control device is used to control the air conditioner; obtaining the ambient temperature of the environment where the indoor unit of the air conditioner is located; determining a target verification method corresponding to the infrared signal according to the ambient temperature; the target verification method includes respectively verifying the high and low levels of the infrared signal; or verifying the sum value of the high and low levels of the infrared signal; verifying the infrared signal according to the target verification method to obtain a verification result; the verification result is used to indicate whether the infrared signal is normal; through the above technical solution, the verification method of the infrared signal can be adjusted in combination with the ambient temperature, reducing the influence of the ambient temperature on the performance of the verification device, reducing the equipment cost, and improving the accuracy of the verification result.

[0063] Figure 1 is a flowchart of a signal processing method shown according to an exemplary embodiment, as Figure 1 shown, the method is applied to an air conditioner, and the method may include the following steps.

[0064] S101. Obtain an infrared signal emitted by a target control device.

[0065] Wherein, the target control device is used to control the air conditioner.

[0066] Exemplarily, the target control device may be a control device corresponding to the air conditioner, for example, a remote controller. The infrared signal emitted by the target control device can be obtained when it is determined that the air conditioner is in the powered-on state.

[0067] S102. Obtain the ambient temperature of the environment where the indoor unit of the air conditioner is located.

[0068] S103. Determine a target verification method corresponding to the infrared signal according to the ambient temperature.

[0069] Among them, the target verification method includes respectively verifying the high level and the low level of the infrared signal; alternatively, verifying the sum value of the high level and the low level of the infrared signal.

[0070] S104. According to the target verification method, verify the infrared signal to obtain a verification result.

[0071] Among them, the verification result is used to characterize whether the infrared signal is normal.

[0072] Through the above technical solution, the verification method of the infrared signal can be adjusted in combination with the ambient temperature, the influence of the ambient temperature on the performance of the verification device is reduced, the equipment cost is reduced, and the accuracy of the verification result is improved.

[0073] In some embodiments, the signal type of the infrared signal includes a header code or a data code, and the above step S102 may include: when determining that the signal type of the infrared signal is a data code, obtaining the ambient temperature of the environment where the indoor unit of the air conditioner is located.

[0074] In some other embodiments, the signal type of the infrared signal can be determined to be a data code in the following manner: when determining that the infrared signal does not include an end code, determining the signal type of the infrared signal as the data code according to the reception time interval between the infrared signal and the previously received historical infrared signal. Exemplarily, when determining that the infrared signal does not include an end code, it is determined that the transmission of the current infrared signal is not over, so that the header code and the data code of the infrared signal can be distinguished according to the time interval, simplifying the discrimination method of the header code and the data code and improving the accuracy of signal verification.

[0075] It should be noted that, in some embodiments, when determining that the infrared signal includes an end code, it can be determined whether the infrared signal is completely received according to the frame value of the infrared signal. And when determining that the infrared signal is completely received, a new infrared signal emitted by the target control device is obtained.

[0076] Exemplarily, when the frame value is greater than or equal to a preset frame number threshold, it is determined that the infrared signal is completely received; when the frame value is less than the preset frame number threshold, it is determined that the infrared signal is not completely received.

[0077] In some embodiments, determining that the infrared signal does not include an end code may include: when determining that the width value of the high level of the infrared signal is not within a first preset range and the width value of the low level of the infrared signal is not within a second preset range, determining that the infrared signal does not include the end code.

[0078] It should be noted that when it is determined that the width value of the high level of the infrared signal is within the first preset range and the width value of the low level of the infrared signal is within the second preset range, it is determined that the infrared signal includes the end code. At this time, it can be determined that the emission of the infrared signal ends, so as to obtain a new infrared signal emitted by the target control device.

[0079] In some other embodiments, determining that the signal type of the infrared signal is the data code according to the reception time interval between the infrared signal and the previously received historical infrared signal may include: when it is determined that the reception time interval is less than or equal to a preset time threshold, determining that the signal type is the data code. And, it may also be determined that the signal type is the header code when it is determined that the reception time interval is greater than the preset time threshold.

[0080] Exemplarily, the preset time threshold may be between 50-100 ms, for example, 50 ms, 70 ms, 80 ms or 100 ms, etc., which is not limited here. In this way, the signal type of the infrared signal can be determined according to the size relationship between the reception time interval and the preset time threshold, realizing the distinction between the header code and the data code, without distinguishing the header code and the data code according to the width values of the high and low levels, improving the accuracy of the verification result, and further improving the work efficiency.

[0081] It should be noted that when it is determined that the signal type is the header code, it is determined that the infrared signal has ended, and a new infrared signal emitted by the target control device can be obtained to enter a new round of signal processing.

[0082] In some embodiments, step 103 above may include: when it is determined that the ambient temperature is less than or equal to a preset temperature threshold, using the verification of the high level and the low level of the infrared signal respectively as the target verification method; or, when it is determined that the ambient temperature is greater than the preset temperature threshold, using the verification of the sum value of the high level and the low level of the infrared signal as the target verification method.

[0083] Exemplarily, the preset temperature threshold can be set by the user, which is not limited here. For example, the preset temperature threshold may be in the range of -5-5 °C, such as -5 °C, 0 °C or 5 °C, etc. In this way, the corresponding verification method can be determined in combination with the ambient temperature, reducing the influence of the ambient temperature on the accuracy of the verification result. And, it reduces the influence of the ambient temperature on the performance of the receiving device, enabling the receiving device to have no high performance requirements, improving the yield rate of the receiving device products, and further reducing the production cost of the receiving device and saving resources.

[0084] In some other embodiments, the target verification method may include verifying the high level and the low level of the infrared signal respectively; the above step S104 may include: when it is determined that the width value of the high level of the infrared signal is within a third preset range and the width value of the low level of the infrared signal is within a fourth preset range, determining that the verification result of the infrared signal is normal.

[0085] In some other embodiments, the target verification method may include verifying the sum value of the high level and the low level of the infrared signal; the above step S104 may include: when it is determined that the sum value of the high level and the low level of the infrared signal is within a fifth preset range, determining that the verification result of the infrared signal is normal; the fifth preset range is greater than the third preset range; the fifth preset range is greater than the fourth preset range.

[0086] It should be noted that the above multiple preset ranges are all set by the user and are not limited here. Among them, the third preset range is greater than the standard range of the high level of the data code, and the fourth preset range is greater than the standard range of the low level of the data code. In this way, the threshold of the verification range is expanded, thereby improving the accuracy of the verification result.

[0087] For example, define the standard value of the high level width as H, and the corresponding standard range of the high level width is (H - Δ1, H + Δ2); the standard value of the low level width is L, and the corresponding standard range of the low level width is (L - Δ3, L + Δ4); the standard value of the sum width of the high level and the low level is A, A = H + L, and the corresponding standard range of the sum width is (A - Δ5, A + Δ6). Since the actual high level value or low level value of the received infrared signal is different from the standard value, here define the actual width value of the high level as H1, and the third preset range is (H - Δ7, H + Δ8); the actual width value of the low level is L1, and the fourth preset range is (L - Δ9, L + Δ10); the actual width value of the sum of the high level and the low level is A1, A1 = L1 + H1, and the fifth preset range is the same as the sum standard range, which is (A - Δ5, A + Δ6).

[0088] Among them, the third preset range (H - Δ7, H + Δ8) is smaller than the sum standard range (A - Δ5, A + Δ6); the fourth preset range (L - Δ9, L + Δ10) is smaller than the sum standard range (A - Δ5, A + Δ6). And, the third preset range (H - Δ7, H + Δ8) is greater than the high level standard range (H - Δ1, H + Δ2), and the fourth preset range (L - Δ9, L + Δ10) is greater than the low level standard range (L - Δ3, L + Δ4).

[0089] When it is determined that H1 is within the third preset range (H - Δ7, H + Δ8) and L1 is within the fourth preset range (L - Δ9, L + Δ10), it is determined that the verification result of the infrared signal is normal. Alternatively, when it is determined that A1 is within the sum value standard range (A - Δ5, A + Δ6), it is determined that the verification result of the infrared signal is normal.

[0090] In some embodiments, it is possible to determine whether the infrared signal includes an end code according to the ambient temperature. When it is determined that the ambient temperature is less than or equal to the first preset temperature threshold, the high level and the low level of the infrared signal are respectively verified to determine whether the infrared signal includes an end code. Alternatively, when it is determined that the ambient temperature is greater than the first preset temperature threshold, the sum value of the high level and the low level of the infrared signal is verified to determine whether the infrared signal includes an end code.

[0091] Exemplarily, when it is determined that the ambient temperature is less than or equal to the first preset temperature threshold, and it is determined that the width value of the high level of the infrared signal is within the first preset range and the width value of the low level of the infrared signal is within the second preset range, it is determined that the infrared signal includes an end code; when it is determined that the width value of the high level of the infrared signal is not within the first preset range and the width value of the low level of the infrared signal is not within the second preset range, it is determined that the infrared signal does not include an end code.

[0092] Moreover, when it is determined that the ambient temperature is greater than the first preset temperature threshold, and it is determined that the sum value of the high level and the low level of the infrared signal is within the sixth preset range, it is determined that the infrared signal includes an end code; when it is determined that the sum value of the high level and the low level of the infrared signal is not within the sixth preset range, it is determined that the infrared signal does not include an end code. Among them, the sixth preset range is greater than the first preset range; the sixth preset range is greater than the second preset range. In this way, it is possible to determine whether the infrared signal includes an end code in combination with the ambient temperature, avoiding the influence of the ambient temperature on the accuracy of the verification result.

[0093] In some other embodiments, it is possible to determine whether the infrared signal includes a start code in combination with the ambient temperature. It can be understood that the specific steps for determining the start code can be the same as the specific steps for determining the end code described above, and will not be elaborated here.

[0094] Figure 2 is a flowchart of another signal processing method shown according to an exemplary embodiment. As Figure 2 shown, the method may include the following steps:

[0095] S201. Obtain the infrared signal emitted by the target control device.

[0096] S202. Determine whether the infrared signal includes an end code.

[0099] S203. Determine whether the signal type of the infrared signal is a data code according to the reception time interval between the infrared signal and the previously received historical infrared signal.

[0100] Wherein, the signal type includes a data code or a header code.

[0101] If it is determined that the signal type of the infrared signal is a data code, perform step S204;

[0102] If it is determined that the signal type of the infrared signal is not a data code, return to step S201.

[0103] S204. Obtain the ambient temperature of the environment where the indoor unit of the air conditioner is located.

[0104] S205. Determine whether the ambient temperature is less than or equal to a preset temperature threshold.

[0105] If it is determined that the ambient temperature is less than or equal to the preset temperature threshold, perform steps S206 - S207;

[0106] If it is determined that the ambient temperature is greater than the preset temperature threshold, perform steps S208 - S209.

[0107] S206. Take the verification of the high level and the low level of the infrared signal respectively as the target verification method.

[0108] S207. If it is determined that the width value of the high level of the infrared signal is within a third preset range and the width value of the low level of the infrared signal is within a fourth preset range, determine that the verification result of the infrared signal is normal.

[0109] S208. Take the verification of the sum value of the high level and the low level of the infrared signal as the target verification method.

[0110] S209. If it is determined that the sum value of the high level and the low level of the infrared signal is within a fifth preset range, determine that the verification result of the infrared signal is normal.

[0111] Wherein, the fifth preset range is greater than the third preset range; the fifth preset range is greater than the fourth preset range.

[0112] Through the above technical solution, the verification method of the infrared signal can be adjusted in combination with the ambient temperature, reducing the influence of the ambient temperature on the performance of the verification device, reducing the equipment cost, and improving the accuracy of the verification result.
