Abstract

The embodiment of the application provides an infrared remote control signal receiving method, an infrared remote control signal receiving system, infrared remote control signal receiving equipment and a storage medium. The method comprises the steps: receiving an infrared pulse through a first thread, and sequentially storing the pulse duration data of the infrared pulse into a first data sequence; acquiring one-bit pulse duration data stored in the first data sequence through a second thread; judging whether the time interval between the pulse duration data and the previous pulse duration data is overtime or not; if not, storing the pulse duration data in a second data sequence, and performing infrared remote control decoding on the pulse duration data stored in the second data sequence;and if the second data sequence is overtime, emptying the second data sequence, and continuing to acquire next pulse duration data stored in the first data sequence. According to the embodiment of the application, when the infrared remote control signal is received, the loss of new pulse data due to untimely receiving caused by overlong decoding processing time can be prevented, and the accuracyof receiving and decoding the infrared remote control signal is improved.

Description

technical field [0001] The embodiments of the present application relate to the field of infrared remote control, and in particular to a method for receiving an infrared remote control signal, a receiving system, a receiving device, and a storage medium. Background technique [0002] Infrared remote control is one of the commonly used remote control methods in daily life. At present, the infrared remote control decoding is mainly based on instant decoding, but to execute a command operation needs to receive multiple pulses and perform data analysis. This instant decoding method is easily disturbed. [0003] NEC protocol is a commonly used infrared remote control protocol. NEC protocol includes boot code, 16bit address code, 8bit data code and 8bit data code inverse code. There are three common interference phenomena: (1) There is interference before the boot code; ( 2) There is interference in the boot code; (3) There is interference in the address bits or data bits. The re...
