The present disclosure provides a method for recognizing crackles, including: processing collected lung sound signal to extract moist rale component for a respiratory cycle; calculating a power spectrum of the moist rale component, and, calculating at least one of a ratio of power of each preset frequency band to total power of all preset frequency bands and the total power of all the preset frequency bands as a frequency domain parameter, and/or calculating at least one of a ratio of the number of occurrence of moist rale and a maximum amplitude of moist rale in the entire inspiratory phase as a time domain parameter; inputting the frequency domain parameter and/or the time domain parameter serving as a parameter feature into a classification model for recognition. The present disclosure further provides a system for recognizing crackles.

Method and system for recognizing crackles

A street lamp integration device, a street lamp system and a communication method are disclosed. The street lamp integration device includes a local area network module configured to generate a local area network covering a first range, a traffic collector configured to collect traffic information in a second range and send the same to a communication module and the communication module configured to send the traffic information to a vehicle connected to the local area network. By extensive availability and close mutual distance of street lamps, a local area network is formed within the first range of each street lamp, which helps to to form a network of comprehensive coverage and extensive range. The traffic collector can collect traffic in a certain range and send the same to the vehicle connected to the local area network through the communication module, facilitating awareness of the current traffic by the vehicle.
