Abstract
The method includes following steps: designing pulse switching circuit connected to sensor in electric quantity or non electric quantity for controlling light emitting device to send out pulses of optical flare; defining fixed cycle T of each flare, and bright and extinguished durations in cycle are half to half; N times of continuous flare express coded number N, and extinguished state between two numbers as interval To; N is outputting coded digital information; setting up correspondence list between coded number and information in advance etc. light emitting devices in multiple colors can be utilized to distinguish digit positions of coded numbers. For example, N1, N2, and N3 times of continuous flare in different colors means that the coded digit number N is N3X100+N2X10+N1. Transfer time t between different colors is a blank interval. Number is coded in decimal system or in M scale. Features are: simple, and high reliability.
