Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0029] The embodiment of the present invention uses an error correction algorithm to insert a supervisory bit into the key value to form a codeword, and the code value is sent out after infrared modulation, and the receiving host performs error correction processing on the received codeword according to the supervisory bit, and restores the key value information, thereby Significantly enhance the anti-interference ability of the remote control signal.

Abstract

The invention is applied to the communication field, and provides a transmitting method, a receiving method, a device and a system for an infrared remote control signal. The transmitting method of the infrared remote control signal comprises the following steps of: scanning a pressed key value of a remote controller; inserting a check fit in the scanned key value; and sending a codon inserted into the check fit after infrared modulation. According to the invention, the check fit is inserted into the key value of the infrared remote controller by an error-correction algorithm, and an infrared remote control receiving host machine corrects errors for the received codon to reduce the key value information, so that the anti-interference capacity of the infrared remote control signal can be greatly enhanced.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to an infrared remote control signal sending method, receiving method, equipment and system. Background technique [0002] Infrared remote control is a kind of wireless and non-contact control technology, which has the advantages of strong anti-interference ability, reliable information transmission, low power consumption, low cost, and easy implementation. It is widely used by many electronic devices, especially household appliances. However, in practical applications, infrared remote control signals are often interfered by light and electromagnetic interference in the environment, which may cause the remote control to fail or shorten the distance of the remote control. In order to reduce interference, the usual method is to add a filtering algorithm to the software, or add a shield to the infrared remote control receiver (Infrared Remote Control Receive Module, IR), which is ...
