Embodiment

[0018] see figure 1 , this embodiment provides a fixed code length complementary coding method for an infrared remote control, the infrared remote control adopts a complementary coding method, that is, each byte is coded, followed by the byte Inverse code, and a check code is set in the fixed code length; corresponding decoding rules are compiled on the receiving controller that matches the infrared remote control, which is used to receive the infrared code sent by the infrared remote control, and according to the original code, Inverse code and check code to judge the confirmation data.

[0019] In this embodiment, the fixed code length means that the number of bytes sent each time is stipulated in the communication protocol to be fixed, which is beneficial to judging whether the received data is lost, and also conducive to technical standardization.

[0020] In this embodiment, the check code adopts a one-byte code, and each binary bit of the check code represents the parit...

Abstract

The invention relates to a fixed code length complementary type coding method for an infrared remote controller. According to the method, the infrared remote controller adopts the complementary type coding mode, i.e. each byte is coded, the ones-complement code of the byte tightly follows behind the byte, and in addition, a check code is set in the fixed code length; and corresponding decoding rules are correspondingly compiled on a receiving controller matched with the infrared remote controller and are used for receiving infrared codes sent by the infrared remote controller, in addition, the data can be confirmed and judged according to the original code, the ones-complement code and the check code, when the original code of the data has error codes, the correct data can also be recovered according to the ones-complement code and the check code, and the anti-interference capability is improved.

Description

technical field [0001] The invention relates to a fixed code length complementary coding method for infrared remote controllers, which is applied to various infrared remote controller fields, such as infrared remote controller products with a remote distance of less than 45 meters, such as televisions, stereos, air conditioners, and LED lighting fixtures. Background technique [0002] Currently used infrared remote control products, the remote control coding scheme used only adopts a fixed code length method, which has certain defects in code sending and receiving reliability, especially those products that require high reliability for one-time code sending and receiving. It will directly affect product use and performance. Such as LED ceiling light products, one of them is called unattended automatic switch light function, through the infrared remote control setting, a certain lighting mode is turned on and off at regular intervals, and when the timing is up, the remote con...
