Detailed Description
In order to make the technical problems solved, technical solutions adopted and technical effects achieved by the present invention clearer, the technical solutions of the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, the method for responding to a remote control key provided in this embodiment is applicable to a scenario where an electronic device responds to a remote control key command sent by a remote controller, and the method can be executed by a remote control key responding apparatus configured in the electronic device, and the apparatus can be implemented in a software and/or hardware manner.
As shown in fig. 1, the method for responding to a remote control key provided in this embodiment may include the following steps:
and S110, receiving a remote control key instruction.
S120, analyzing a key code pulse carried by a remote control key instruction; if the pulse reading time of the current logic bit is not more than the set time, judging that the current logic bit is logic 0; if the pulse reading time of the current logic bit is greater than the set time, judging that the current logic bit is logic 1; wherein the setting time is less than the pulse reading time of logic 1 defined by the standard protocol.
Optionally, the setting time in this embodiment is preferably 900 μ s.
In the prior art, the electronic device decodes according to the length of the pulse based on a standard protocol (such as NEC protocol, Sharp protocol, etc.) by interrupting reading of the key pulse transmitted from the remote controller, and reports the decoded data to the upper application. For example, a standard protocol in the prior art provides that a pulse read time is between 800 μ s and 900 μ s, corresponding to a logic 0, and a pulse read time is between 1500 μ s and 1700 μ s, corresponding to a logic 1; in order to ensure the accuracy of the analysis result, during actual analysis, the specified pulse reading time reaches 850 mus, the logic 0 is judged, and the pulse reading time reaches 1600 mus; this determination method, a judgment in the code, is to regard the pulse read time as a logical 0 if it is within a certain range, and a logical 1 if it is within another range.
This embodiment is an improvement of the standard protocol, and specifies that the pulse read time does not exceed 900 μ s, and the determination is logical 0, and the pulse read time exceeds 900 μ s, and the determination is logical 1.
In a specific embodiment, when the electronic device receives a remote control key instruction sent by a remote controller and analyzes a key code pulse carried by the remote control key instruction, for a single pulse, if the pulse reading time reaches 850 μ s and does not exceed 900 μ s, the current logic bit is determined to be logic 0; if the pulse reading time exceeds 900 μ s, the current logic bit is determined to be logic 1, and the current logic bit is determined to be logic 1 without reading the complete pulse length, so that the analysis time of the logic bit 1 is shortened by (1600 μ s-900 μ s) to 700 μ s compared with the prior art.

In this embodiment, the pulse parsing method improved based on the standard protocol greatly shortens the parsing time of the logic bit 1, for example, if the electronic device receives one remote control key command each time, the corresponding key code value has 32 bits, if 16 bits of the key code value are logic bit 1, the parsing time can be saved by (700 μ s × 16) ═ 11200 μ s, and if the electronic device receives consecutive remote control key commands, more parsing time can be saved.
In summary, in the technical solution of this embodiment, when the electronic device analyzes the key code pulse carried by the remote control key instruction, the logic 1 pulse time defined by the standard protocol is shortened to implement the fast reading determination of the logic 1, so that the response speed and the operation fluency of the electronic device to the remote control key instruction are greatly improved, and especially when the user continuously presses the key, more response time can be saved, and the user experience is improved.
Preferably, between S110 and S120, further comprising: and analyzing a head code in the remote control key command, and executing the analysis operation of the key code pulse when the head code is analyzed correctly (namely S120).
For example, when the electronic device receives a remote control key instruction, the electronic device analyzes the header code, and if the reading time of the first pulse is within a set interval, the electronic device confirms that the first pulse is the header code pulse, and then starts to receive and analyze the key code pulse. By analyzing and confirming the head code, the electronic equipment can be ensured to accurately identify the remote control key command sent by the remote controller.
