Abstract
The invention provides a wireless communication device based on a high power light emitting diode (LED). The wireless communication device comprises a data transmitting and receiving controller A, a data transmitting and receiving controller B, an optical receiver A, an optical receiver B, a high power LED A, a high power LED B, a constant current power supply A, and a constant current power supply B. The constant current power supply A is used for driving the high power LED A. The constant current power supply B is used for driving the high power LED B. The data transmitting and receiving controller A controls the high power LED A to blink rapidly. If the high power LED A is on, the data is high and is one; if the high power LED A is off, the data is low and is zero. The optical receiver B receives data sent by the high power LED A in a binary form. The data in binary form is cached in the data transmitting and receiving controller B to be processed. The data transmitting and receiving controller B processes the received data and sends out response information through the high power LED B. The optical receiver A receives the response information and caches in the data transmitting and receiving controller A so as to complete wireless communication.
Description
Technical field
The present invention relates to a kind of wireless communication apparatus based on great power LED, belong to electronic application field.
Background technology
Current use more widely the short distance wireless communication technology is bluetooth (Bluetooth), WLAN (wireless local area network) 802.11 (Wi-Fi) and infrared data transmission (IrDA), also have some to have the low coverage wireless technology standard of development potentiality simultaneously, they are respectively: ZigBee, ultra-wideband (Ultra WideBand), short-range communication (NFC), WiMedia, GPS, DECT, wireless 1394 and private radio systems etc., the feature that they have it to base oneself upon, or based on the particular/special requirement of transmission speed, distance, power consumption; Or be conceived to the extendibility of function; Or meet the special requirement of some single application; Or set up the differentiation etc. of competitive technologyL, but these wireless telecommunications radio waves transmit Content of Communication.
Radio wave can produce certain electromagnetic radiation; relevant expert points out; different people or same person are different in the ability to bear of Different age group to electromagnetic radiation; old man, children, pregnant woman are the crowds to electromagnetic radiation sensitivity; resistance is more weak, should be to lay special stress on protecting object, simultaneously; a lot of family all uses wireless Internet access now, and the synergistic effect of wireless radiation also can not be ignored.
In addition because radio wave needs certain transmitting power when completing radio communication, the power consumed is reactive power consumption mostly.
Summary of the invention
The present invention is intended to provide a kind of wireless communication apparatus based on great power LED, for wireless telecommunications and illumination, avoids the electromagnetic radiation producing larger intensity.
To achieve these goals, the present invention proposes following technical scheme:
Based on a wireless communication apparatus for great power LED, comprising: data transmit/receive control unit A, data transmit/receive control unit B, optical receiver A, optical receiver B, great power LED A, great power LED B, constant-current supply A, constant-current supply B; As accompanying drawing 1;
Constant-current supply A is for driving great power LED A, constant-current supply B is for driving great power LED B, data transmit/receive control unit A controls great power LED A fast blink, namely 1 do not work as data are low by namely 0 so that great power LED A is bright for data height, optical receiver B receives the data that great power LED A sends in binary form, binary data is cached to data transmit/receive control unit B process, echo message is sent by great power LED B by the data that data transmit/receive control unit B process receives, optical receiver A receives response data and is cached to data transmit/receive control unit A and completes wireless telecommunications.
Above-mentioned great power LED optical communication make use of the high speed scintillation of LED light, achieves transmission and the communication of data, and owing to being the flicker of millions of times per second, beyond the resolution capability of human eye, human eye cannot experience its superfast flicker.
Above-mentioned great power LED A, great power LED B can provide illumination.
