Embodiment Construction

[0010] A method for encoding and decoding infrared pulse signals of the present invention comprises the following steps:

[0011] Step 1. Set the control command emitted by the infrared controller to be stored in the format of "code length + control code + index number + library content", where the control code refers to the configuration information of this infrared code, including an infrared Code cyclically sent signs, carrier frequency, infrared "bank" address information, each pair of high level and low level in the infrared pulse signal is called a "bank", and the high level width value corresponding to the "bank" and The low level width value is called a "bank content";

[0012] Step 2. The learning-type infrared remote control device starts to receive the remote control command of the button emitted by the infrared controller, first reads the first library, the initial value of the index number is 0, and the obtained high level width value and low level width value St...

Abstract

The invention provides a decoding / coding method of infrared pulse signal. In the method, a studying-type infrared remote-controlling device receives a remote-controlling command of buttons, wherein the remote command is sent by an infrared controller. A controlling command sent by the infrared controller is stored in a manner of a format including a code length + a controlling code + an index number + library content. If the library contents are same, a repeatedly storing operation is not carried out and only the library content which is read at the first time is stored. Same library content is enabled to be corresponding to the same index number. When the controlling command is restored, the library content, which is corresponding to the index number, is read according to the index number, so that when the remote-controlling command is stored, stored data can be compressed so that a storage space of the data can be effectively compressed.

Description

technical field [0001] The invention relates to a method for encoding and decoding infrared pulse signals. Background technique [0002] With the continuous improvement of people's consumption level, higher requirements are put forward for the ease of use and affinity of home appliances. It has become a trend to introduce information technology and network technology into the field of home appliance production, giving birth to intelligent, personalized, and easier-to-control information home appliances, and smart homes are imperative. How to integrate many traditional home appliance remote controls and intelligently control home appliances through a more user-friendly remote control device with a user interface has become a research direction for everyone. [0003] At present, a mature method is to integrate many traditional infrared remote controllers into a learning infrared remote control device, and then use the learning infrared remote control device to control all hom...
