The positions of the urban cleaning vehicles are different in different time periods, and the load condition of the urban cleaning vehicles can be acquired according to the thermodynamic diagram. Some garbage monitoring areas have more garbage, the load of the needed city clearance vehicles is smaller, and the city clearance vehicles with closer distances are preferentially used for garbage clearance treatment. Therefore, each marked area is provided with the corresponding most suitable urban cleaning vehicle for garbage cleaning treatment, and finally, the urban cleaning vehicles are subjected to vehicle scheduling treatment according to urban traffic conditions and garbage cleaning sequences. The method can analyze the real-time position and the load condition of the clearing vehicles in the city, and realize the vehicle dispatching of the clearing vehicles in the city.
Fig. 2 shows a flow chart of a method for analyzing the space-time characteristics of the garbage monitoring area and performing associated early warning on the garbage monitoring area, which comprises the following steps:

It should be noted that, there are space-time features in the garbage monitoring area, and the space-time features include temporal features and spatial features. The time characteristics and the space characteristics of the garbage monitoring area can be obtained by using the TCN model and the RNN model respectively. The time characteristic means the change condition of the quantity of garbage in the garbage monitoring area in different time periods, and the space characteristic means the change condition of the position of the garbage in the garbage monitoring area. Acquiring the space-time characteristics of the garbage monitoring area is helpful for providing conditions for the subsequent acquisition of the garbage characteristics of the garbage monitoring area and the associated early warning of the garbage monitoring area.
Further, in a preferred embodiment of the present invention, the obtaining the second type of garbage monitoring area based on the relative distance between the garbage monitoring areas specifically includes:

It should be noted that, there may be large activities around the garbage monitoring area, such as food streets, and garbage is easy to be generated, so that it is necessary to obtain environmental parameters around the garbage monitoring area, and combine the space-time characteristics of the garbage monitoring area and the garbage type information to obtain the garbage characteristics of the garbage monitoring area. The trash characteristics represent the number, location, type and impact of trash in the trash monitoring area. The garbage in the garbage monitoring area may be related to each other, for example, the garbage in the first garbage monitoring area may flow to the second garbage monitoring area along with the factors of people flow, traffic flow, etc. And acquiring the relative distance between the garbage monitoring areas, wherein the garbage monitoring area with the relative distance within a preset value is regarded as a large monitoring area, and is defined as a garbage monitoring area. The garbage monitoring areas in the garbage monitoring areas are not necessarily associated, so that a gray association method is required to be used for acquiring association values of garbage features in the garbage monitoring areas, and the garbage monitoring areas with association values larger than a preset value are defined as the garbage monitoring areas. All the garbage monitoring areas in the second-class garbage monitoring area can be mutually influenced.

and when the signal intensity of the garbage characteristic abnormal signal is larger than the second signal intensity threshold value, generating the garbage characteristic abnormal signal in the garbage monitoring area to be detected.
It should be noted that the number and distribution position of the garbage in the garbage monitoring area may change, and the abnormal condition of the garbage features includes that the number of the garbage is increased, the position where the garbage is located is not suitable, and the like, so that the garbage features of the garbage monitoring area are monitored in real time in the three-dimensional model of the urban road, and a garbage feature abnormal signal is generated. Because each rubbish monitoring area in the second class rubbish monitoring area can influence each other, when rubbish characteristic abnormal signals exist in the second class rubbish monitoring area, other rubbish monitoring areas need to be subjected to early warning treatment, and the purpose is to predict rubbish characteristic changes of the rubbish monitoring areas in advance and to make corresponding measures in advance.

In addition, it should be noted that the garbage may pollute the air, and part of the garbage, such as industrial garbage, chemical garbage, etc., may pollute the air and then pollute the human health, so in the garbage cleaning process, air quality parameters of the garbage monitoring area are obtained, where the air quality parameters include element components in the air, volatile concentration of compounds, etc. If the air quality parameters are unqualified, elemental components and the like in the air can cause harm to the environment and human body. Therefore, when the air quality parameters are unqualified, people in the garbage monitoring area need to be monitored in real time, the people with the face without the obstructer mean people without wearing a mask or people with the face fully exposed in the air, and the people with the face without the obstructer are easily affected by air pollution, so that if the people with the face without the obstructer are detected, warning and driving treatment is needed to be carried out on the people.
