Problems solved by technology
At present, most TV remote controllers on the market can only remotely control the TV, and select and switch channels for it. The defect is that the selection and switching are blind and random, which can no longer meet the needs of users for fast and convenient TV program selection.
In addition, some TV supplementary devices with guiding functions and multiplexing devices embedded with TV supplementary devices have also appeared on the market, such as the device with the patent No. ZL00238171.0, but these devices have complex structures, and the single TV supplementary It needs to be purchased specially, and it needs to be installed and occupy a certain space, or it can be embedded in other devices for compound use, causing inconvenience

Embodiment Construction
[0017] exist figure 1 In the block diagram of the structural principle, the present invention receives a variety of information sent by the paging station through the wireless paging interface, and stores the information in the remote control device, which is convenient for users to search, select information, switch, and control, and then controls the electrical appliances through the infrared emitting head of the remote control device .
[0018] Such as figure 2 The hardware system shown is mainly composed of the following parts: RF front-end, decoder, main processor MCU, keyboard, LCD display, FLASH memory and infrared transmitter. The RF front-end includes a low-noise amplifier LNA, an intermediate frequency circuit IF, and an A / D converter. Its function is to realize the conversion of the radio frequency signal to the intermediate frequency signal until the binary code stream; the function of the decoder is to complete the decoding of the received binary information. ,...

The hardware of device consists of the RF front end, the decoder, the MCU, the keyboard, the LCD display screen, the FIASH memory and infrared emission head. The software system consists of interrupt routine and main program. The interrupt routine deals with real time event such as key and reception to produce system message and event tag. The main program inquires the relevant system message and event tag to make relevant control process. The technical point of the invention is: using the wireless pager reception terminal, infrared remote controller and digital information processing method for handheld device to make real time storage, display and real time searching for local and intraday information through pager station.
Description
technical field [0001] The invention relates to an intelligent remote control device, which belongs to the technical field of telecommunications. Background technique [0002] The appearance of the remote control makes it convenient for people to select and switch various electrical appliances. However, with the development of electrical appliances, the remote control has more and more functions, such as TV remote control. With the increase of TV stations and the access of home cable TV, The TV channel that the user can watch generally can reach 30-50. At present, most TV remote controllers on the market can only remotely control the TV, and select and switch channels for it. The defect is that the selection and switching are blind and random, which can no longer meet the needs of users for fast and convenient TV program selection. . In addition, some TV supplementary devices with guiding functions and multiplexing devices embedded with TV supplementary devices have also a...
