Problems solved by technology

Before use, you need to use the original remote control to learn, record the signal waveform of each function of the original remote control, and the number of learning is limited
[0006] (3) The user interface is not friendly
The function corresponding to a button on the remote control is specified through learning, which is not intuitive, especially when there are many functions, it is easy to confuse
[0007] (4) The information between the remote control and the home appliance is one-way communication, and the status of the home appliance cannot be queried through the remote control

Embodiment Construction

[0054] The new universal remote control mainly includes four components: core processing unit, external storage unit, wireless communication unit, and human-machine interface unit, see figure 1 .

[0055] Wireless communication unit: This part mainly completes the sending and receiving of radio frequency signals.

[0056] When the remote controller wants to send a control command to the home appliance, the processor obtains the corresponding control command according to the device file stored in the external memory, and sends it to the wireless communication unit; after the wireless communication unit completes signal modulation and power amplification, it transmits the control signal It is transmitted in the form of radio frequency; when the home appliance returns to the device state, the wireless communication unit receives the radio frequency signal sent by the home appliance, and performs filtering, demodulation and A / D conversion on the signal, and finally gives the retur...

Abstract

The universal remote controller includes kernel processing unit, outer memory unit, radio communication unit, and man-machine interface unit. The radio communication unit is for RF signal sending and receiving, the kernel processing unit for RF base band signal processing, read access of outer memory, input processing of keyboard, LCD output and display, analysis of the equipment file, communication protocol processing, etc.; the outer memory unit for storing equipment files of household appliance and the man-machine interface unit for man-machine interaction. The method of using the universal remote controller in controlling household appliance includes four steps of equipment browsing, equipment control, state enquiry and equipment management.

Description

technical field [0001] The invention relates to a universal remote controller and a method for controlling household electrical appliances by using the same. Background technique [0002] At present, most of the home appliance remote controls used in the home use infrared communication. When users use them, they require that there should be no obstruction between the remote control and the home appliances, or that they should work by reflection. At the same time, due to the large number of home appliance manufacturers, each manufacturer has many different models of the same home appliance, and different home appliances have different functions, it is difficult to ensure that the remote controllers of each home appliance are universal. However, there are often many different home appliances in the user's home, so there are multiple different remote controllers in the home at the same time, which is inconvenient for the user to use and causes waste of equipment. [0003] Now ...
