Infrared remote control carrier-free coding method

Abstract

The invention discloses an infrared remote control carrier-free coding method, which comprises the following steps that an infrared remote control sending end sends a complete data frame, and the complete data frame structurally comprises a 1-bit synchronization bit, an 8-bit user check code, an 8-bit user code, an 8-bit data check code, an 8-bit data code and a 1-bit end bit; after the infrared remote control receiving end receives the data frame, the user check code and the user code as well as the data check code and the data code are checked respectively; and the infrared remote control sending end repeatedly sends the complete data frame. The coding rule is simple, the single code time is short, the number of data bits of the data frame is small, and the decoding timeliness of the remote control receiving end is greatly improved; the coding method is compatible with an infrared receiving tube of an infrared induction product control panel, an infrared receiving head and other hardware circuits do not need to be additionally arranged, the coding method adapts to the intermittent working characteristic of an infrared induction product, the detection time of a remote control signal of a remote control receiving end is shortened, and the low energy consumption characteristic of the control panel is kept.

Description

technical field [0001] The invention relates to the technical field of communication coding, in particular to a carrierless coding method for infrared remote control. Background technique [0002] In reality, many infrared sensing products have introduced infrared remote control function in order to realize the contact-free setting of working parameters, improve the efficiency of production debugging and the convenience of daily maintenance. According to the current carrier coding method, it is necessary to add an infrared receiver to complete the amplification and demodulation of the remote control signal. The system block diagram, data frame structure diagram and data bit definition diagram of the carrier coding method are respectively as follows figure 1 , 2 As shown in , 3, this coding method not only increases the cost of the product, but also increases the size of the control board, which affects the integration and miniaturization of the product, and also increases t...
