[0003] There are many ways to realize infrared data storage. For example, when storing data, allocate a certain space for the data in advance. The advantage of this method is that the storage is more convenient, but it wastes a lot of precious space. It is very inconvenient, and if a lot of infrared data needs to be stored, the amount of infrared data that can be stored will be limited due to factors such as capacity

Embodiment Construction
[0031] The present invention will be further elaborated below in conjunction with the accompanying drawings.
[0032] A method for learning and accessing infrared data based on a communication device, the main steps of which include:
[0033] 1. By sampling and detecting the frequency of infrared rays, the remote control can learn infrared data.
[0034] As shown in Figure 1, when the infrared signal is received, it is first sampled, and the time t1 and t2 of the pulse are calculated, and stored in the first and second bits of the data buffer. The specific calculation method of t1 and t2 is as follows: Timely count the high and low levels of the pulse through timer 0 and 1 respectively. When the level is high, start timer 0 and start timing of high level; when the level jumps When turning low, turn off timer 0, and save the calculated time, start timer 1 at the same time, time the low level; when the level jumps to high, turn off timer 1, and save the calculated time, and at ...

The invention discloses a communication equipment based infrared data study and access method which belongs to the field of application communication field, and in particular relates to a realization method that renders the associate mapping of a key code table with an infrared data storage table to store and read the infrared data. The method first samples and studies the infrared data, and stores the infrared data in the infrared data storage table, and then, related definitions are carried onto the key code table and the related start addresses of the infrared data in the storage table are stored onto the corresponding key positions in the key code table, and at last, the key value utilization equation (infrared data address=L*equipment type number+key value*3+1) is used to work out the corresponding address of the infrared data in the key code table; through reading the content of the address, the positions of the infrared data in the infrared data storage table can be known. The method can be used to greatly save the storage room of the infrared data and obtain a relatively high-efficient flexible infrared data acquisition way.
Description
technical field [0001] The invention belongs to the field of applied communication, and in particular relates to a realization method for storing infrared data and reading infrared data by using the association mapping of a key value table and an infrared data storage table. technical background [0002] Due to the generalization of communication, especially infrared communication, and infrared communication has many communication advantages such as miniaturization, low cost, high speed and high security, it is very suitable for remote control. Therefore, to achieve remote control with radio frequency devices, it is extremely important to convert radio frequency signals into infrared control signals, thereby realizing infrared remote control. Therefore, how to efficiently and flexibly realize the learning and storage of infrared knowledge has become extremely important. [0003] There are many ways to realize infrared data storage. For example, when storing data, allocate a...
