Embodiment

[0035] Step 1. Obtain real-time anonymous encrypted mobile phone data from the mobile phone communication operator in real time, use a dedicated decryption module to decrypt and convert coordinates, and map it to a specific urban geographic location in real time. The decrypted data includes EPID (anonymous single EncryPtioninternationalmobilesubscriberIDentity), TYPE (the mobile network action type involved in the current record), TIMESTAMP (the time stamp of the mobile network action involved in the current record), LON (real longitude coordinates), LAT (true latitude coordinates), SR (spatial error range).

[0036] The decrypted data in this embodiment is shown in Table 1 below.

Abstract

The invention aims at providing a method for collecting spatial population distribution in real time on the basis of mobile phone big data and realizing large passenger flow early warning. The method is characterized by comprising the following steps of obtaining real-time mobile phone big data from a mobile phone communication operator at each statistics moment; dividing a target region into different space regions; at the current statistics moment, mapping the latest space position of each EPID (Electronic Portal Imaging Device) obtained in the first step to each space region of the target region; and obtaining the real population size (the distribution condition of the total population in the whole target region) in each space region at the current statistics moment. The method has the advantages that the sufficient relying on the existing mobile phone big data resources is realized; the continuous encrypted position information of the existing mass anonymous mobile phone users in the mobile communication network is used; the low-cost high-frequency and automatic implementation can be realized; and the popularization distribution data in a large-range urban space range can be continuously obtained in a fast deploying way.

Description

technical field [0001] The invention relates to a method for collecting urban population spatial distribution data in real time based on massive anonymous encrypted mobile phone big data, and sending early warning information in time when the passenger flow is large (close to the regional population carrying limit), which is used for high-frequency and automatic acquisition The spatial distribution data of urban population can serve urban operation management, urban planning, and policy evaluation and formulation, and belongs to the technical field of urban operation management and urban planning. Background technique [0002] The coordinated development of regional population, resources, and environment is one of the trends in economic and social development, and the integration of population, resources, environment, and other economic and social information for comprehensive analysis is the basic condition for solving regional population, resource, and environmental problem...
