Abstract

Description
- This application claims priority to and the benefit of U.S. Provisional Patent Application 62/033,816, filed Aug. 6, 2014, which is incorporated by reference herein in its entirety.
- The invention relates generally to a collapsible smart fence and uses thereof. Specifically, the invention relates to a collapsible smart fence for effectively detecting and handling crowd behaviors.
- In planned crowded events, like festivals and parades, a high risk factor is that the event attracts too many people or that people are not distributed evenly enough around the event. This can lead to disasters such as the 2010 Love Parade where 21 people died and 510 people got injured as a result of a large crowd of people being led through a tunnel. It is challenging for operators in a command and control center to assess the crowdedness of an area, because available sensors such as cameras, microphones and social media might not be able to give a perfect picture of the situation.
- Most crowd controlling fences are created with the goal of keeping people out under all circumstances. The fences are made of heavy materials such as steel to resist strong forces and are typically installed for permanent deployment. Since these fences are permanent fences, they do not facilitate the crowd to move to the buffer zone when necessary, especially during emergency.
- A fence intuitively instructs people to keep out of an area. When conditions are normal, people are expected to respect these constraints and the fence will remain untouched. However, as more extreme conditions arise (e.g. an area gets overcrowded, people panic, or people get very drunk) people will start to ignore the constraint the fence imposes on them and will start jumping over the fence or breaking the fence down. The existing fences do not effectively detect such people and their behaviors.
- Certain existing crowd analytics solutions rely on video analytics or audio analytics for extracting crowd relevant statistics that can be of use to an operator in a command and control center. These analytic operations are computationally expensive and have high memory requirements for processing.
- Certain other existing smart fences use string wires in combination with sensors, motion detectors or general MEMS sensors to detect intrusion from cutting the wire fence or climbing over it. However, such fences are also designed with a fixed, permanently deployed fence in mind, intended to keep out intruders at all times.
- Accordingly, there exists a need for an improved fence for effectively detecting and handling crowd behaviors.
- In one aspect, the invention provides a collapsible fence comprising: one or more sensors, wherein each sensor is capable of sensing one or more parameters; a plurality of connecting mechanisms, wherein each connecting mechanism is capable of connecting a plurality of fence components when one or more of the sensed parameters do not breach a predetermined threshold limit and capable of disconnecting said plurality of fence components when one or more of the sensed parameters breach said predetermined threshold limit, and wherein said fence collapses when said plurality of fence components are disconnected.
- In another aspect, the invention provides a collapsible fence system comprising: one or more sensors, wherein each sensor is capable of sensing one or more parameters; a plurality of connecting mechanisms, wherein each connecting mechanism is capable of connecting a plurality of fence components; an analysis unit, said analysis unit comprising a data receiving module that receives data associated with said one or more parameters from said sensor; a determining module that determines whether a predetermined threshold limit for said one or more parameters is breached; a triggering module that triggers one or more of said connecting mechanisms to disconnect their corresponding fence components, in response to a breach for said one or more parameters, thereby collapsing said fence.
- In yet another aspect, the invention provides a method for making a collapsible fence, the method comprising: providing one or more sensors, wherein each sensor is capable of sensing one or more parameters; providing a plurality of connecting mechanisms, wherein each connecting mechanism is capable of connecting a plurality of fence components when one or more of the sensed parameters do not breach a predetermined threshold limit and capable of disconnecting said plurality of fence components when one or more of the sensed parameters breach said predetermined threshold limit, and wherein said fence collapses when said plurality of fence components are disconnected.
- In a further aspect, the invention provides a method for managing a crowd, the method comprising: providing a collapsible fence of the invention; receiving data associated with said one or more parameters from said sensor; determining whether said predetermined threshold limit for said one or more parameters is breached; when no breach occurs, keeping the connections of one or more of said plurality of connecting mechanisms, in order to connect with said plurality of components of said fence to provide an intact fence; and when breach occurs, turning off said one or more connecting mechanisms to disconnect the plurality of components, thereby triggering said fence to collapse.

It should be understood, however, that the detailed description and the specific examples while indicating preferred embodiments of the invention are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this

a determining module that determines whether a predetermined threshold limit for said one or more parameters is breached;
a triggering module that triggers one or more of said connecting mechanisms to disconnect their corresponding fence components, in response to a breach for said one or more parameters, thereby collapsing said fence.
24. A method for making a collapsible fence, the method comprising:
providing one or more sensors, wherein each sensor is capable of sensing one or more parameters;
providing a plurality of connecting mechanisms,
wherein each connecting mechanism is capable of connecting a plurality of fence components when one or more of the sensed parameters do not breach a predetermined threshold limit and capable of disconnecting said plurality of fence components when one or more of the sensed parameters breach said predetermined threshold limit, and
wherein said fence collapses when said plurality of fence components are disconnected.
25. A method for managing a crowd, the method comprising:
providing a collapsible fence of claim 1 ,
receiving data associated with said one or more parameters from said sensor;
determining whether said predetermined threshold limit for said one or more parameters is breached;
when no breach occurs, keeping the connections of one or more of said plurality of connecting mechanisms, in order to connect with said plurality of components of said fence to provide an intact fence;
when breach occurs, turning off said one or more connecting mechanisms to disconnect the plurality of components, thereby triggering said fence to collapse.
