Wherein A ═ { a ═ a1,a2,a3Is an index of importance of various factors, a1Indicates the evaluation factor u1Weight of a2Indicates the evaluation factor u2Weight of a3Indicates the evaluation factor u3Weight of a1+a2+a3And R is a fuzzy evaluation matrix of fuzzy relation between the passenger flow evaluation factor set and the passenger flow index evaluation level.
5. The system of claim 4, wherein the fuzzy evaluation matrix is as follows:
wherein r isijAnd representing the membership degree of the passenger flow evaluation factor set relative to the passenger flow index evaluation level.
6. The system of claim 4 or 5, wherein the set of passenger flow assessment factors is:
U＝{u1,u2,u3}；
wherein u is1Indicates the number of persons arriving at the station per unit time u2Indicating the total length of the team at the ticket office, u3Indicating the density of the waiting area.
7. The system according to claim 3 or 4 or 5, characterized in that the passenger flow index rating is:
V＝{v1,v2,v3}；
wherein v is1Indicating less passenger flow, v2Indicating a greater volume of passenger, v3Indicating a burst of passenger flow.
8. A method of buffering passenger flow based on the system of claim 1 or 2, comprising the steps of:
s1, counting passenger flow data through the collected images, dividing the passenger flow convergence and divergence degree into three passenger flow evaluation levels by adopting a fuzzy comprehensive evaluation method, and judging the passenger flow evaluation level to which the current passenger flow convergence and divergence degree belongs to obtain a corresponding passenger flow buffer mode signal;
s2, controlling the intelligent warning line units to deploy according to the preset distribution according to the passenger flow buffer mode signal, if a passenger enters the area of the passenger flow buffer channel in the deployment process, sending an alarm to remind the passenger to exit the area, and prompting the passenger to go on after the deployment is finished; the intelligent warning line units in the non-deployment state are connected and arranged on the side of the passenger flow buffer channel, and when an emergency evacuation state occurs, the connection between the intelligent warning line units automatically bounces open and guides passengers to evacuate and evacuate.
