[0003] 1. There are more and more remote controls at home. Sometimes the electrical appliances have been replaced, but the remote controls are still there. It is a pity that these remote controls are thrown away. It is useless to keep them, and other electrical appliances are not compatible.
[0004] 2. More and more smart appliances and smart homes use infrared remote control, but the infrared remote control of these smart homes is only used to realize the simplest "on" and "off" functions, but it is also equipped with a remote control, although the cost is not high , but too many remote controls are troublesome
Because there are many states of the air conditioner, it must be sent at one time, including cooling, temperature, wind speed, automatic, timing, humidification, heating, etc., so the code is very long, and the same key will send different codes in different states. Find out It is still very difficult to decode the remote control code (ie full code) of all infrared remote controls

Embodiment 1
[0079] Reference attached Figure 5 , attached Figure 7 with attached Figure 9 , a kind of infrared remote control signal decoding method based on microprocessor, described continuous monitoring method comprises the following steps:
[0080] (1) First, the infrared remote controller sends an infrared remote control signal;
[0081] (2) In the second step, the infrared receiver amplifies, detects and shapes the received infrared remote control signal, and outputs it to the microprocessor;
[0082] The microprocessor processes the signal as follows;
[0083] (3) The third step is to carry out 10ms debounce processing to the signal received by the microprocessor;
[0084] (4) The 4th step, carry out time interval calculation to the signal after the 3rd step processing;
[0085] (5) In the fifth step, the microprocessor judges whether the infrared signal received by the microprocessor is greater than 0.01~0.1s to the time interval calculation result; if so, the cumulative t...

[0093] Reference attached Figure 5 , attached Figure 8 with attached Figure 10 , a microprocessor-based infrared remote control signal decoding method, the interval monitoring method comprises the following steps:
[0094] (1) First, the infrared remote controller sends an infrared remote control signal;
[0095](2) In the second step, the infrared receiver amplifies, detects and shapes the received infrared remote control signal, and outputs it to the microprocessor;
[0096] The microprocessor processes the signal as follows;
[0097] (3) The third step is to carry out 10ms debounce processing to the signal received by the microprocessor;
[0098] (4) The 4th step, carry out time interval calculation to the signal after the 3rd step processing;
[0099] (5) In the fifth step, the microprocessor judges whether the infrared signal received by the microprocessor is over to the time interval calculation result; if so, the cumulative time is cleared; if not, the delay int...

Abstract
The invention provides a decoding mode for carrying out timing treatment on received 38KHz infraredsignal, wherein the timing treatment on received 38KHz infraredsignal specifically indicates that the accumulating time for receiving the 38KHz infraredsignal once reaches a certain time length. The second target of the invention is to provide a specific instruction method of the mode; and the instruction method is one of an interval monitoring method or a continuous monitoring method. According to the mode provided by the invention, the function realized by infrared signal matching learning can be achieved without infrared signal matching learning. Compared with a bluetooth with a switch function, the operation is relatively convenient and the cost is relatively low. The infrared remote controller decoding mode provided by the invention is matched with an intellectual electric apparatus; intelligent control on interrupt when the electric apparatus is in standby or is shut down can also be achieved; opening is convenient when power supply is needed again, so that energy sources are saved, and the operation is simple and easy.
Description
technical field [0001] The invention relates to the technical field of infrared remote controlsignal decoding, and in particular to a decoding method for any infrared remote control signal without infrared signal matching and learning, based on this method. Background technique [0002] With the development of society and the needs of use, more and more infrared remote controllers are used. On the one hand, it does bring convenience to people's lives, but at the same time, the following situations have also been found through research: [0003] 1. There are more and more remote controls at home. Sometimes the electrical appliances have been replaced, but the remote controls are still there. It is a pity that these remote controls are thrown away. It is useless to keep them, and other electrical appliances are not compatible. [0004] 2. More and more smart appliances and smart homes use infrared remote control, but the infrared remote control of these smart homes is only us...
