The invention provides an information transmitting and receiving device and a maintenance method and system thereof. The information transmitting device comprises a storage device which stores geographical position information of the information transmitting device; a processor which is connected with the storage device and processes the geographical position information so as to generate a positioning message and encodes the positioning message so as to generate a control instruction; a controller which is connected with the processor and controls on / off of a light wave emitter by utilizing the control instruction; and the light wave emitter which is connected with the controller and outputs light positioning information under the control of the control instruction. A special information encoding and decoding technology is adopted so that the interval period of light information is shortened, light encoding frequency is enhanced, and the problem of strobe frequency is solved without the requirement of using a camera to be aligned with light or the problem of excessive exposure of the camera, and thus anti-interference capacity is high and use is convenient and the information transmitting and receiving device can be used for route navigation and can also be used for consumption navigation.
Description
technical field [0001] The invention belongs to the technical field of communication and relates to a communication method, in particular to an information sending and receiving device and its maintenance method and system. Background technique [0002] Because large shopping malls, underground parking garages and other places cannot receive satellite signals, navigation software that relies on satellite signals cannot provide users with navigation services because they cannot obtain correct location information. Currently, there are a variety of solutions being researched and explored, including WIFI, RFID, Bluetooth, ZegBee and other technologies, which cannot be implemented because of low precision or high cost. There are also places where the use of radio signals is not allowed, which also makes positioning difficult. [0003] In comparison, the method of light positioning can achieve higher accuracy, but it obtains the signal through the camera and obtains the informat...
