Embodiment 1

[0020] An infrared coded signal receiving device connected with a smart phone through a bluetooth mode, its composition includes: a bluetooth module 7 with a microprocessor function, said bluetooth module is respectively connected with a state display LED10, a bluetooth start button 9, a USB module 11, The electronic compass 8 and the 3.8V rechargeable battery 12 are connected, the RX terminal of the serial port of the Bluetooth module is connected to the output terminal OUT of the electronic switch 6, and the signal input terminals 1, 2 and 3 of the electronic switch are respectively connected to two infrared receivers The digital output end of demodulation module 3, described electronic compass, described bluetooth module and smartphone 13 are connected by bluetooth mode, and the box body front side and the outside of described infrared coded signal receiving device are respectively provided with shading cover 2. The hood limits the range of the receiving angle of the infrare...

Embodiment 2

[0022] According to the infrared coded signal receiving device connected with the smart phone through bluetooth in the embodiment 1, the box body of the receiving device has glasses leg clips, which can be conveniently fixed on various glasses legs. The electronic switch control terminal C is connected to the TX end of the Bluetooth module serial port, and the controlled terminal I of the electronic compass is connected to the control terminal OUT of the Bluetooth module for controlling whether the electronic switch outputs during the control sequence. The azimuth digital signal of the electronic compass, the bluetooth module is connected to an external computer for program testing and modification, and for charging the rechargeable battery.

Embodiment 3

[0024] According to the infrared coded signal receiving device connected with the smart phone through bluetooth in the embodiment 1 or 2, the infrared code received by the infrared coded signal receiving device is composed of 3 parts: the 1-3 digits of the first part are guide Code, the 4th digit is the output control code of the electronic compass azimuth information; the 2nd part is the calling file code, the said file is an audio format file or a text format file; the 3rd part is the network address code, when the 3rd part=0000 , the file code in the second part is to call the local file, that is, the file stored in the smart phone in advance, otherwise, the file stored on the network is called. The file corresponding to each code is stored in the smart phone or on the network, one code corresponds to one audio file, or one code corresponds to one or one text file.

Abstract

An infrared coded signal receiving device connected to a smartphone via Bluetooth. The current infrared coding control technology is mainly in the field of home appliance control, and its application range is relatively narrow. The present invention comprises: a bluetooth module (7) with a microprocessor function, the bluetooth module is respectively connected with the status display LED (10), the bluetooth start button (9), the USB module (11), the electronic compass (8), and the 3.8V The rechargeable battery (12) is connected, the RX end of the serial port of the Bluetooth module is connected to the output end OUT of the electronic switch (6), and the signal input ends 1, 2, and 3 of the electronic switch are respectively connected to two infrared receiving demodulation modules (3), the electronic compass The digital output terminal of the Bluetooth module is connected with the smart phone (13) installed with the application software through Bluetooth, and the front side and the outside of the box body of the infrared coded signal receiving device are respectively provided with hoods (2). The invention is used for receiving infrared coded signals.

Description

Technical field: [0001] The invention relates to an infrared coding signal receiving device connected with a smart phone installed with application software through bluetooth. Background technique: [0002] The current city's road information (road name, house number,) signs, public facilities (public toilets, bus stops), commercial signs (shops, restaurants, product advertisements), tourist attraction signs (detailed introductions to attractions, road guidance), most The print media marked with text and pictures is aimed at normal people and local people, and it does not work for the blind and people who do not understand the local language, and GPS can only be manually set and searched, which is very inconvenient for on-site use. There is no connection with current computer technology and network technology. [0003] The disadvantages of using the existing Bluetooth, WIFI, barcode and 2D technologies for the above applications: 1) The coverage area is small, requiring man...
