Description

A Smartphone That Can Replace Your Remote

Technical field:

The utility model relates to a mobile phone, in particular to a smart mobile phone which is simple in structure, convenient to use and can replace a remote controller.

Background technique:

With the continuous development of science and technology, people's demand for household appliances is increasing day by day, and daily necessities such as TV sets, set-top boxes, VCD/DVD, air conditioners and combined audio systems have entered thousands of households. However, because the remote controllers of existing household appliances are not universal, people are troubled by the large number of remote controllers while enjoying various household appliances, and the phenomenon of inconvenient use of electrical appliances due to the loss of remote controllers also occurs from time to time. . At present, mobile phones have a high penetration rate and have multiple functions, but they do not have the function of a remote controller.

Invention content:

In order to solve the above-mentioned technical problems existing in the prior art, the utility model provides a smart phone with a simple structure, convenient use and a substitute for a remote controller.

The technical solution of the utility model is: a smart phone that can replace the remote control, has a single-chip microcomputer, and is connected with the single-chip computer with a matrix keyboard, a memory and a display, and is characterized in that: an infrared emitting device and an infrared receiving device are connected with the single-chip computer .

The utility model is provided with an infrared transmitting and receiving device on the existing mobile phone, and the code of the remote control of the household appliance can be memorized through the infrared receiving device, and the stored code is set on the key of the mobile phone by using the software in the smart phone. The remote control of household appliances can be completed by pressing the buttons of the mobile phone, so that a mobile phone can be used to control various electrical appliances in the family. The structure is simple and the operation is convenient, which eliminates the annoyance caused by the large number of remote controllers.

Description of drawings:

Fig. 1 is the circuit principle block diagram of the embodiment of the utility model.

Detailed ways:

The specific embodiment of the utility model will be described below in conjunction with the accompanying drawings. As shown in Figure 1: the utility model embodiment is the same with existing mobile phone, has single-chip microcomputer (AT89S52), is connected with single-chip microcomputer and has matrix keyboard, storage device (EEPROM) and display (LED), and what is different from existing mobile phone is and The single-chip microcomputer is connected with an infrared emitting device and an infrared receiving device.

Working principle: The single-chip microcomputer constitutes the processor of the infrared remote control, and its own data memory RAM (258B) is used to store the pulse width of the coded signal of the remote control. When in use, first use the infrared receiving device to collect the original signal of the remote control of the household appliance very precisely, and cache the original signal to the RAM, then analyze the collected source signal and compress and encode it, and store the compressed and encoded data in the In E ² PROM, determine the corresponding matrix keyboard at the same time. When needed, the mobile phone can be set in the remote control state, the keyboard is operated, and the corresponding code is sent out through the infrared emitting device, thereby controlling the corresponding household appliances.

Claims (1)

1. the smart mobile phone of an alternative remote controller has single-chip microcomputer, is connected to matrix keyboard, memory and display with single-chip microcomputer, it is characterized in that: be connected to infrared launcher and infrared receiving device with single-chip microcomputer.
