Method for realizing network download infrared remote control function by mobile phone

In the following detailed description, specific details are described in order to provide a thorough understanding of the present invention. Those skilled in the art will recognize, however, that the invention may be practiced with other similar details.

Accompanying drawing 1 is the schematic diagram that supports the infrared remote control mobile phone internal block diagram of the present invention method and remote control household appliance, and the difference with common mobile phone is to have added specially designed infrared transmitting and receiving microprocessor chip (abbreviation infrared chip). In order to facilitate two-way communication with the main processor of the mobile phone, the infrared chip is designed with a hardware SPI interface. The SPI interface is a widely available hardware interface for the main processor of the mobile phone. In order to occupy the computing bandwidth of the main processor of the mobile phone as little as possible, the infrared chip supports software programming, which can flexibly realize the emission function of various infrared remote control protocols, and perform simple compression and identification processing on the received infrared remote control code data. Then upload to the main processor of the mobile phone. The infrared chip is designed in a standby mode. Within a preset period of time, if the command of the main processor of the mobile phone is not accepted, the infrared chip will automatically enter the standby mode from the working mode. The standby current is less than 3uA, which is almost No effect. When the main processor of the mobile phone needs to transmit, it wakes up the infrared chip through an interrupt, and sends the infrared code pattern and its protocol corresponding to the user's key to the infrared chip for processing and transmission. If the user selects the learning mode, the main processor of the mobile phone commands the infrared chip to enter the learning receiving mode by waking up the infrared chip. As mentioned above, the infrared remote control function of the mobile phone mainly relies on the infrared chip processing, which occupies very little computing bandwidth for the main processing of the mobile phone, ensuring that other normal functions of the mobile phone, such as calls and text messages, are not affected by the infrared remote control function.

The method of the present invention does not have special requirements to the main processor of the mobile phone shown in accompanying drawing 1, can be the digital baseband processor of non-smart mobile phone, also can be the application processor in the middle of smart mobile phone, supports the various functions of smart mobile phone and non-smart mobile phone

The main processor of the mobile phone solution, with universal applicability.

It needs to be specially explained that the home appliance in the middle of Figure 1 is a TV set, which is only used for illustrative purposes. The method of the present invention supports various types of home appliances including air conditioners, TV sets, set-top boxes, stereos, DVDs, etc. that support infrared remote control.

Accompanying drawing 2 is the schematic diagram that the infrared remote control mobile phone of the present invention accesses the remote control code database through the Internet. As shown in Figure 2, the infrared remote control mobile phone accesses the Internet through wireless, and the remote control code database is stored in the server of the Internet, and there is a specific website for access. The user searches the network database according to the model of the home appliance to be remotely controlled, and downloads the corresponding remote control code to the middle of the mobile phone. If the user cannot find the model of the home appliance that needs to be remote controlled in the database, the user needs to use the learning mode of the infrared remote control mobile phone to perform key-by-key learning operations. The remote control code data received by the infrared remote control mobile phone will also be automatically uploaded to the network database. middle. There are professional remote control code database maintenance personnel who can maintain and upgrade through terminals connected to the Internet. With the increase of user groups, the network remote control code database will continue to get new data uploaded by users, but the newly uploaded remote control code data needs to be reviewed and sorted out by professional database maintenance personnel before it can become official network searchable data. The advantage of this design is that on the one hand, it ensures that the models of household appliances not included in the database can be quickly collected, and on the other hand, it ensures the correctness and completeness of the data that can be retrieved by users in the middle of the database.

While the description herein describes certain features and one method of implementing the invention, many modifications, substitutions, changes and equivalents will occur to those skilled in the art. Accordingly, the protection scope of the present invention shall be determined by the scope of the appended claims.
