Description
Technical field
The present invention relates to a kind of natural science museum medium intelligent introduction system based on visible ray and power line carrier, PLC, belong to short-distance wireless communication technology field and power line carrier cable communicating technology field.
Background technology
At present, along with the quick propelling of Internet of Things (Internet of things) technology and industry, the dream of carrying out information exchange whenever and wherever possible progressively is achieved.Internet of Things had both depended on the short-range communication technique such as wireless sense network (Wireless Sensor Network, WSN), RFID (Radio Frequency Identification), also be unable to do without the infrastructure such as mobile radio communication, Internet.Short haul connection all adopts airwave communication, although this mode is widely used, exists human body is produced to harm, communication equipment many defects such as easily generation interferes with each other, frequency resource is limited.
In recent years, the development of the manufacturing technology of novel semi-conductor efficient high brightness white light emitting diode LED, the LED luminous efficiency progressively is improved; And, under national energy-saving reduction of discharging policy promotes, its application has progressively expanded to lighting field from the demonstration field, and obtained development at a high speed.With traditional lighting apparatus, compare, white light LEDs belongs to cold light source, has low in energy consumptionly, and the life-span is long, and size is little, the advantages such as environmental protection, be counted as the 4th generation energy saving and environment friendly illuminating product.It is exactly that response sensitivity is very high that white light LEDs also has an outstanding advantages, therefore can carry out the communication of ultrahigh speed short-range data with LED.Visible light communication (Visible-Light Communication, VLC) is exactly a kind of in the technical a kind of emerging short distance visible ray wireless communication technology grown up of white light LEDs.
And low voltage power line carrier (low Power Line Carrier, PLC) communication is in the situation that need not newly-built new traffic circuit, the main transmission channel of the original low pressure 220V electric main supply line arranged as high-frequency communication signal of utilizing, for transmitting required data message, as remote control signal, voice messaging, image information etc., it has that transmission rate is high, the power line wideband transmit, without plurality of advantages such as private communication wiring, applied ranges, can realize that indoor user utilizes the multiple business such as power line is made a phone call, online, Long-distance Control.Carrying out research and the test of low-voltage distribution Network Communication abroad as countries such as the U.S., Japan, Israel.And use low-voltage power line to advance group " Home Plug Power Line Alliance " as the home network that transmits information media by 13 company's amalgamated consolidations such as U.S. 3COM, Intel, Cisco, PANASONIC, it has proposed family's socket (Home Plug) plan, the digitlization indoor communications that to be intended to promote to take power line be the transmission information medium.Family's plug-in in June calendar year 2001 alliance has formulated indoor power line communication standard HomePlug 1.0, its Theoretical Rate 14Mbps; Formulated again about data retransmission standard Home Plug AV such as HDTV, VoIP in December, 2005, its Theoretical Rate 200 Mbps; And take up to formulate Home Plug AV 2.0, maximum rate 600Mbps from March, 2009." HD-PLC Wavelet OFDM " standard of being formulated by " HD-PLC " alliances of the company formations such as PANASONIC, IO.DATA, AOPEN AMERICA, Advanced Communication Networks SA (CAN), OKI, Murata Manufacturing Co. Ltd. was adopted by the IEEE P1901 committee in January, 2010, and became international standard; The broadband P LC standard " G.hn " (50 ~ 700Mbps) that " Home Grid Forum " alliance of being set up by Intel, TI, Best Buy, Panasonic, 14 companies such as Infenion, DS2 in addition formulates was passed through at Geneva, Switzerland on June 15th, 2010, became international standard.But in many standards, G3 and PRIME are foremost two standards wherein, and the G3 standard is relatively focused on system robustness, and for the two-way communication standard has the effective data rate of 400Kbps, and allow the power line carrier communication signal to pass through low-tension transformer and be dispensed to medium-voltage line, reduced link cost, made power-line carrier communication become current application focus.
