[0044] Here, the exemplary embodiments will be described in detail, and the examples are shown in the accompanying drawings. When the following description refers to the accompanying 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 merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0045] First, the application scenario of the present disclosure is introduced. The present disclosure is applied to the scenario of infrared signal detection. Infrared remote control is a widely used device control method, and the control signal is often transmitted through a fixed carrier frequency.

[0046] In the related art, infrared remote control can be applied to various household appliances, such as air conditioners; the remote control can control the startup, shutdown, or temperature adjustment of the air conditioner through infrared signals. With the development of technology, infrared remote control can be applied to more types of household appliances. However, there are many types of household appliances, and the carrier frequencies of the control signals are relatively close. When controlling a certain household appliance through infrared remote control, it is easy to receive signal interference from another household appliance, resulting in the phenomenon of insensitive remote control reception.

[0047] To solve the above problems, the present disclosure provides a method, device, and electronic device for signal detection; the device includes a signal transmission module, a signal processing module, and a control module; the signal transmission module is connected to the control module through the signal processing module; the signal transmission module is configured to periodically send infrared signals to the signal processing module; the signal processing module is configured to obtain the verification information corresponding to the infrared signal; and send the verification information to the control module; the control module is configured to match the verification information with the preset verification information to obtain a matching result; and determine the transmission state of the infrared signal according to the matching result; the transmission state indicates whether the infrared signal is interfered; by setting the signal transmission module, the emission of infrared signals can be controlled to simulate the actual transmission scenario of infrared signals; and, the infrared signal can be verified in real time through the control module to determine whether the infrared signal is interfered; and, the infrared signal is verified periodically, so as to be able to determine the interference situation of the infrared signal in time.

[0048] Figure 1 is a block diagram of a signal detection device shown according to an exemplary embodiment, such as Figure 1 shown, the device 100 may include a signal transmission module 110, a signal processing module 120, and a control module 130; the signal transmission module 110 is connected to the control module 130 through the signal processing module 120;

[0049] The signal transmission module 110 is configured to periodically send infrared signals to the signal processing module 120.

[0050] Exemplarily, the signal transmission module may send infrared signals to the signal processing module at intervals of a preset time range; wherein, the preset time range can be set by the user, for example, 5 min or 10 min, etc., which is not limited here.

[0051] The signal processing module 120 is configured to obtain the verification information corresponding to the infrared signal; and send the verification information to the control module 130.

[0052] Exemplarily, the signal processing module may decode the infrared signal to obtain the verification information corresponding to the infrared signal.

[0053] The control module 130 is configured to match the verification information with preset verification information to obtain a matching result; and determine the transmission state of the infrared signal according to the matching result; the transmission state indicates whether the infrared signal is interfered with.

[0054] Exemplarily, the verification information may be the carrier frequency and / or communication protocol of the infrared signal. The preset verification information may be the specified carrier frequency and / or specified communication protocol of the infrared signal preset by the user. Among them, the carrier frequency is the same as the specified carrier frequency, and the communication protocol is the same as the specified communication protocol. In this way, it is possible to quickly determine whether the infrared signal is interfered with according to the matching result of the verification information and the preset verification information, improving work efficiency.

[0055] In some embodiments, the signal detection device may be applied to an electronic device. Exemplarily, the electronic device may be an air conditioner or a display panel of an air conditioner. The signal transmitting module and the signal processing module may be within the same cavity structure. For example, both the signal transmitting module and the signal processing module may be within the display panel of the air conditioner.

[0056] For example, the carrier frequency of the infrared signal emitted by the signal transmitting module may be the same as the carrier frequency of the remote control device (such as a remote control) corresponding to the electronic device. In this way, the self-check of the infrared signal by the electronic device can be realized through the signal transmitting module, avoiding the situation where the corresponding electronic device cannot be accurately controlled due to signal interference during the use of the remote control device, and improving the user experience.

[0057] By setting the signal transmitting module, the emission of the infrared signal can be controlled to simulate the actual transmission scenario of the infrared signal; and the infrared signal can be verified in real time through the control module to determine whether the infrared signal is interfered; and the infrared signal is verified periodically, so as to be able to determine the interference situation of the infrared signal in a timely manner.

[0058] In some embodiments, the control module 130 may be configured to determine that the infrared signal is not interfered with when it is determined that the matching result is a successful match; or determine that the infrared signal is interfered with when it is determined that the matching result is a failed match. In this way, it is possible to determine whether the signal is interfered with according to the matching result, realizing the detection of the infrared signal.

[0059] In other embodiments, the control module 130 may be configured to determine that the infrared signal is interfered with when it is determined that the matching result fails continuously for a first preset number of times. Exemplarily, the first preset number may be in the range of 2-4 times, such as 2 times, 3 times or 4 times, etc. The first preset number can be set by the user according to the actual situation and is not limited here.

[0060] It should be noted that the control module 130 can be configured to determine that the infrared signal is not interfered when it is determined that the matching results of the third consecutive preset times are successfully matched. Exemplarily, the third preset times can be in the range of 1 - 3 times, such as 1 time, 2 times, or 3 times, etc.

[0061] In some embodiments, the control module 130 is further configured to control the signal transmitting module 110 to send multiple infrared signals to the signal processing module 120 within a preset time range when it is determined that the matching result of the current cycle meets the preset detection conditions; the preset detection conditions include that the matching result of the current cycle is successfully matched and the matching result of the previous cycle is failed to be matched; the signal processing module 120 is further configured to decode each of the multiple infrared signals to obtain multiple pieces of verification information; and send the verification information to the control module; the control module 130 is further configured to match each piece of verification information with the preset verification information to obtain the matching result; and determine the transmission state of the infrared signal according to the matching result.

[0062] Exemplarily, the preset time range can be in the range of 20 - 40 s, such as 20 s, 25 s, 30 s, or 40 s, etc., which is not limited herein. The number of the multiple infrared signals can be in the range of 4 - 6, such as 4, 5, or 6, etc., which is not limited herein. The emission interval time of each infrared signal is the same.

[0063] For example, the control module can control the signal transmitting module to continuously emit 5 infrared signals within 30 s, that is, emit one infrared signal every 6 s. Since it is difficult to determine whether the infrared signal is interfered when the matching result of the current cycle is successfully matched and the matching result of the previous cycle is failed to be matched. Therefore, the transmission state of the infrared signal can be quickly determined by the above method, improving the work efficiency.

[0064] In other embodiments, the control module 130 can be configured to determine that the infrared signal is interfered when it is determined that the number of times of failed matching in the matching result is greater than or equal to the second preset times.

[0065] Exemplarily, the second preset times can be in the range of 3 - 5 times, such as 3 times, 4 times, or 5 times, etc., which is not limited herein. The second preset times is less than or equal to the number of emissions of the multiple infrared signals. For example, when the number of emissions of the multiple infrared signals is 5, the second preset times can be 3 times, that is, when there are 3 times of failed matching in 5 infrared signals, it is determined that the infrared signal is interfered.

[0066] Figure 2 is a block diagram of a signal detection device shown according to an exemplary embodiment of Figure 1 , as shown in Figure 2 . The device 100 may further include an alarm module 140; the alarm module 140 is connected to the control module 130; the control module 130 is further configured to send an alarm signal to the alarm module 130 when it is determined that the infrared signal is interfered; the alarm module 140 is configured to output alarm information based on the alarm signal.

[0067] Exemplarily, the alarm module may be an alarm device, such as a buzzer or an indicator light, etc.; it is used to prompt the user that the infrared signal of the device is interfered, so that the user can timely understand the interference situation of the device, avoid being unable to accurately control the device due to signal interference during use, and improve the user experience.

[0068] The working process of the signal detection device is illustrated by way of example below. The signal detection device may include a signal transmission module, a signal processing module, a control module, and an alarm module; the signal transmission module is connected to the control module through the signal processing module; the control device is connected to the alarm device.

[0069] The signal transmission module periodically sends an infrared signal to the signal processing module. The signal processing module decodes the infrared signal, obtains the check information corresponding to the infrared signal, and sends the check information to the control module. The control module matches the check information with the preset check information to obtain a matching result; the matching result may include a successful match or a failed match. The control module may determine that the infrared signal is not interfered when it is determined that the matching result is a successful match. Or, when it is determined that the matching result is a failed match for a continuous first preset number of times, it is determined that the infrared signal is interfered; and an alarm signal is sent to the alarm module. The alarm module outputs alarm information based on the alarm signal.

[0070] In addition, the control module may also control the signal transmission module to send multiple infrared signals to the signal processing module within a preset time range when the matching result in the current cycle is a successful match and the matching result in the previous cycle is a failed match. The signal processing module may decode the multiple infrared signals respectively to obtain multiple pieces of check information; and send the check information to the control module. The control module may match each piece of check information with the preset check information to obtain the matching result; when it is determined that the number of failed matches in the matching result is greater than or equal to a second preset number of times, it is determined that the infrared signal is interfered; at this time, the control module may send an alarm signal to the alarm module. The alarm module outputs alarm information based on the alarm signal.

[0071] By setting up a signal transmitting module, the emission of infrared signals can be controlled to simulate the transmission scenario of actual infrared signals. Moreover, the infrared signals can be verified in real time through a control module to determine whether the infrared signals are interfered. In addition, the infrared signals are verified periodically, so that the interference situation of the infrared signals can be determined in a timely manner.

The device may include a signal transmitting module 110, a signal processing module 120, and a control module 130.

[0076] Among them, the transmission state indicates whether the infrared signal is interfered.

[0077] By setting up a signal transmitting module, the emission of infrared signals can be controlled to simulate the transmission scenario of actual infrared signals.
