Methods, internet of things systems and storage mediums for street management in smart cities

A method for street management in a smart city implemented based on an Internet of Things system for street management in a smart city, wherein the Internet of Things system for street management in a smart city includes a management platform, a sensor network platform, and an object platform, the method is executed by the management platform, and the method comprises:

• obtaining, based on the object platform, street monitoring information of a target area through the sensor network platform;
• determining, according to the street monitoring information, distribution of fallen leaves on the street, the distribution of fallen leaves including a total amount of fallen leaves and a count of fallen leaf piles;
• determining, based on the distribution of fallen leaves, cleaning difficulty of each street in the target area;
• wherein the determining, based on the distribution of fallen leaves, cleaning difficulty of each street in the target area includes:
• determining at least one particle according to at least one fallen leaf pile;
• determining, according to position of the at least one particle, a central position of the at least one particle, and designating the central position of the at least one particle as a center of mass of the at least one particle;
• determining, according to a distance from each particle of the at least one particle to the center of mass, a dispersion degree of fallen leaves;
• determining, according to the dispersion degree of fallen leaves, the cleaning difficulty of each street in the target area;
• determining, based on the total amount of fallen leaves and the cleaning difficulty, at least one street to be cleaned from the target area;
• and
• determining, based on the at least one street to be cleaned, a fallen leaf cleaning route of the target area;
• wherein the determining, based on the at least one street to be cleaned, a fallen leaf cleaning route of the target area includes:
• determining, based on the at least one street to be cleaned, at least one continuous action sequence;
• for any continuous action sequence of the at least one continuous action sequence, determining a reward value of each cleaning action of the continuous action sequence by processing the continuous action sequence based on a preset evaluation function, and determining a return value of each continuous action sequence of the at least one continuous action sequence by recording a total reward value of each cleaning action of the continuous action sequence as a return value of the continuous actions;
• determining, according to each continuous action sequence of the at least one continuous action sequence and the return value of each continuous action sequence, the fallen leaf cleaning route of the target area.
