Document CN105611682a discloses a method and device for controlling an indicator lamp, which converts the flicker frequency of the indicator lamp into a bit map corresponding to the flicker frequency; and controlling the indicator lights to synchronously flash according to the bit map and the multicast message. Document CN106572557B invents a flicker control method and system for LED strings, storing a plurality of display modes in advance; setting a display sequence for the driving chip; combining the display sequences to enable each group of LED lamp strings to be displayed according to the corresponding display modes; therefore, the effects of serial water flashing, mobile flashing or random flashing of a plurality of groups of LED lamp strings are realized by combining the display sequences of each group of LED lamp strings and flashing according to the display modes in sequence. Document CN110868777a discloses a time sequence lighting control method of a smart card and the smart card, which uses control logic contained in a time sequence control circuit to control each lighting source of a lighting device on the smart card to light according to a preset time sequence, the time sequence switches lighting states of the light sources in units of a plurality of clock cycles, and the lighting states of the light sources include: the light emitting time length, the light emitting color, the flicker frequency and the light emitting brightness of different light emitting sources; the data display function of the luminescent smart card can be enhanced. In order to accurately detect the rhythm and the flashing period error of the beacon light, and judge whether the rhythm and the flashing period error meet the requirements of technical standards, a document CN111175025A discloses an intelligent detection method and a device thereof, which adopt remote imaging and tracking to track the position of the beacon light in real time and remotely acquire the optical signal of the beacon light; the remotely acquired optical signals divide the optical signal spectral dispersion of the navigation mark lamp according to the wavelength by a modularized spectrometer, and the characteristic wavelength of the navigation mark lamp to be detected is extracted from the optical signals; an automatic beacon light lamp quality recognition algorithm and a lamp quality database are established, a background recognition algorithm is designed in the beacon light lamp quality recognition algorithm, interference is eliminated, and the beacon light device is subjected to field detection to recognize the lamp quality.
