Abstract

The present invention provides an ultrasonic remote control system for a mobile phone. The system comprises a smart phone, an ultrasonic receiver, and a signal processing module. An App program is installed in the smart phone, where the program sends ultrasonic data of a remote control instruction by using a hands-free loudspeaker of the mobile phone; an ultrasonic receiver is added to a controlled end to receive the ultrasonic data sent by the smart phone, and after the data is received, the received data is decoded to obtain a control signal, so as to control a home appliance device. The cost of the receiver in the ultrasonic remote system of the mobile phone in the present invention is approximately RMB 1.5. The cost is low, the implementation manner is simple, and the system layout is flexible, thereby reducing cost for a user and providing very good application value.

Description

Mobile phone ultrasonic remote control system

Technical field

The invention belongs to the field of intelligent control of household appliances, and in particular relates to an ultrasonic remote control system.

Background technique

With the popularity of smart phones, installing an APP software on mobile phones, using mobile phones to remotely control home TVs, air conditioners, and desk lamps has gradually become a reality. There are currently three mainstream ways to achieve this:

a) Wi-Fi mode: wireless remote control is implemented by using the Wi-Fi module of the mobile phone, and a Wi-Fi communication module needs to be added at the receiving end;

b) Bluetooth mode: wireless control is implemented by using the Bluetooth module of the mobile phone, and a Bluetooth communication module needs to be added at the receiving end;

c) 2.4G mode: 2.4G communication module is externally inserted on the mobile phone, and 2.4G communication module is added at the receiving end.

The above three methods all have the same problem, and the cost is high: the cost of the Wi-Fi module and the Bluetooth module is about 10 yuan, and the 2.4G communication module is slightly cheaper, and it is about 6 yuan.

Summary of the invention

In order to solve the problems in the prior art, the present invention provides a mobile phone ultrasonic remote control system, which can realize a remote control function for home appliances by using a smart phone with a wide popularity and an ultrasonic connector with a cost of about 1.5 yuan.

The invention is achieved by the following technical solutions:

A mobile phone ultrasonic remote control system, characterized in that: the system comprises a smart phone, an ultrasonic receiving head and a signal processing module, wherein the ultrasonic receiving head and the signal processing module are located at a controlled end; the smart phone utilizes the hands-free The call horn sends ultrasonic data of the remote control command; the ultrasonic wave receiving head is configured to receive the ultrasonic data; the signal processing module is configured to decode the received ultrasonic data to obtain a control signal, and implement control of the controlled end device.

As a further improvement of the present invention, the smart phone transmits the ultrasonic data of the remote control signal by using the hands-free speaker horn by installing an App program in the smart phone, and the program ultrasonically encodes the plurality of remote control commands by means of software, and Calling intelligence The hands-free speaker of the mobile phone sends out ultrasonic data.

As a further improvement of the present invention, the signal processing module includes an MCU that decodes the ultrasonic data signal to obtain a control signal, and the control signal controls the controlled end.

As a further improvement of the present invention, the controlled end is a television, an air conditioner, a desk lamp, a washing machine, a refrigerator, a water heater, and an electric fan.

The invention has the beneficial effects that the mobile phone ultrasonic remote control system of the invention comprises a smart phone, an ultrasonic receiving head and a signal processing module. Install an app program on the smartphone, which uses the hands-free speaker of the mobile phone to send ultrasonic data of the remote command; add an ultrasonic receiver at the controlled end to receive the ultrasonic data sent by the smart phone, after receiving the data The control signal is decoded and the control of the household electrical appliance is realized. The cost of the receiving head of the mobile phone ultrasonic remote control system of the invention is about 1.5 yuan, the cost is low, the implementation mode is simple, the system layout is flexible, the cost of the user is saved, and the utility model has good application value.
