Embodiment

[0072] For the train operation diagram of Line S of urban rail transit, see image 3 , the abscissa is the time, the ordinate is the distance, the departure interval of adjacent trains is 120s, and the trains stay at each station for a set time and then leave.

[0073] This calculation example studies the dynamic current limiting scheme of station n in the uplink direction, n is a side platform, and the parameters are set as: C n,max =1840 (people), m=3, m'=1, α=0.2, α'=0.4, β=0.8, β'=0.8, departure interval h=120s. The values ​​of the above parameters are set according to the actual situation of the station and historical statistical data.

[0074] 1. Based on the Wi-Fi signaling data, when train k arrives at station n, the number of passengers waiting on the platform in the uplink direction WP k，n , the number of passengers stuck three times

[0075] Corresponding at this time i.e. WP k,n =1608 (people).

[0076] 2. Station n current limit start decision:

Abstract

The invention relates to a Wi-Fi-signaling-data-based dynamic current limiting method of an urban mass transit. The method comprises: S1, Wi-Fi-signaling-based real-time station passenger flow data obtaining is carried out; S2, Wi-Fi-signaling-based real-time station passenger flow data mining is carried out; S3, according to the real-time passenger flow data, whether a current limiting starting condition is met is determined; if so, a current limiting plan is formulated and the formulate plan is implemented, current limiting information is issued in real time; and if not, the S1 is carried out continuously; S4, whether a current limiting end condition is met is determined; if so, the current limiting is ended; and if not, the a current limiting plan in the S3 is implemented continuously; and S5, current limiting end information is issued. Compared with the prior art, the method has the following advantages: the real-time passenger distribution situation at the station can be obtained comprehensively by the Wi-Fi-signaling-data-based data mining; the decision making basis of the dynamic current limiting plan is perfected; the refined management level of the urban mass transit can be improved; and the large passenger flow risk can be reduced.

Description

technical field [0001] The invention relates to the technical field of urban rail transit passenger flow safety management and control, relates to the application of Wi-Fi real-time signaling data in rail transit passenger flow operation organization, and solves the problems of rail transit large passenger flow operation safety and efficiency, in particular to a Wi-Fi-based Dynamic current limiting method for urban rail transit based on signaling data. Background technique [0002] At present, urban rail transit in Shanghai, Beijing and other cities in my country has entered a new stage of network operation, and the contradiction between rapidly increasing passenger flow demand and limited transportation capacity has become increasingly prominent. On the one hand, the phenomenon of overload operation, crowded carriages, and stranded waiting for some lines during peak hours is becoming more and more serious, causing frequent occurrence of passenger hanging doors and car door ...
