Definitions

  • This invention relates to barrier structures for controlling crowds, primarily of people,and to a method of detecting a potential or actual crowd control problem.
  • carrier structure herein is intended to include any structure which prevents or impedes the movement of people or animals including temporary or portable structures.
  • Barrier structures of various kinds are used to control crowds of people, such as spectators at sports events.
  • the crush barriers, handrails, walls and/or fences may be subjected to high, and even excessive, loading, possibly resulting in failure of the structures.
  • a crowd control barrier structure comprising barrier means; and means to sense the magnitude of force applied to the barrier means by pressure of a crowd thereagainst.
  • the sensing means preferably comprises means to produce an electrical, ultrasonic, optical or hydraulic signal which varies in dependence upon the magnitude of said pressure.
  • Said means may comprise at least one strain gauge, load cell or displacement-responsive transducer.
  • the sensing means is preferably coupled to a remote monitoring station at which the effect of the force can be monitored.
  • a plurality of barrier means may be provided in a particular installation, each provided with respective sensing means, and all of said sensing means may be coupled to a common monitoring station.
  • the or each barrier means may comprise a barrier rail, a handrail or a fence supported by a plurality of support members, or may comprise a wall.
  • a method of detecting a potential or actual crowd control problem comprising monitoring a parameter of a barrier structure, which parameter varies in dependence upon the magnitude of pressure exerted against the barrier structure by the crowd.
  • a barrier structure 1 comprises a plurality of upright posts, such as a post 2, which support a rail 3 or a plurality of rails. At least some of the posts are braced by inclined braces 4. The posts, the rail or rails and the braces may be made of steel, for example.
  • a sensor 5 is provided at the base of at least one of the posts to sense a parameter which varies in dependence upon the force applied to the structure 1 as a result of crowd pressure thereagainst.
  • the sensor 5 may comprise a strain gauge, the output of which varies as a result of bending of the post under the applied force.
  • a sensor 6 may be provided at the base of at least one of the braces. Such sensor may sense tensile or compressive stress induced in the brace.
  • sensors (not shown) may be provided in association with the rail itself.
  • Each sensor may comprise an individual sensor element or a pack of sensor elements, and each element may comprise a load cell, a strain gauge or a displacement-responsive transducer, depending upon the parameter which is to be sensed.
  • the sensors may operate electrically, electronically, magnetically, ultrasonically, by electromagnetic radiation or hydraulically.
  • the or each sensor is preferably coupled by wire, a fibre optic cable, a radio, light or ultrasonic link, or a hydraulic line, as the case may be, to a central receiving station 7, at which the signal from the or each sensor can be monitored.
  • barrier structures may be provided around the enclosure, each provided with sensors, each of which is coupled to the central receiving station 7 or to another receiving station (not shown).
  • signals generated by the sensors are continuously monitored by personnel and/or by automatic monitoring devices at the receiving station or stations. If pressure against any of the barriers reaches a predetermined level at which a potential crowd control or overcrowding problem is indicated, an audible and/or visual alarm is operated and/or automatic or manual means is operated to counter the problem.
  • gates may be manually or automatically closed to prevent the entry of further people into the enclosure or into a section of the enclosure. Alternatively or additionally, gates may be opened manually or automatically to allow people to escape from the enclosure.
  • Such automatic monitoring devices may be implemented by hardware and/or by a suitable data processor and software.
  • Figure 2 shows an alternative form of barrier structure 8 which comprises concrete posts, such as a post 9, supporting a rail 10.
  • a sensor 11 is provided at the foot of the post 9 to detect tensile or compressive stress in the post, depending upon the direction of the force applied to the structure by the crowd. Otherwise, the arrangement can be similar to the Figure 1 embodiment.
  • Figure 3 shows a similar arrangement, but in which the barrier comprises a fence 12 supported by posts, such as a post 13.
  • FIG. 4 shows a wall 14 which includes panels incorporating sensors for sensing pressure exerted against the panels by a crowd.
  • panels 15,16 and 17 of various shapes are illustrated.
  • alternative and/or additional sensors may be provided at any part of the barrier structure where a parameter changes due to force applied to the structure by pressure from the crowd.
  • the monitoring method according to the invention may be used in relation to existing barrier structures by the addition thereto of suitable sensors and associated monitoring equipment.
  • suitable sensors and associated monitoring equipment Alternatively, purpose-built barriers incorporating the sensors may be installed.
  • the provision of sensors in the barrier structures may also assist in the design of suitable structures for a particular situation.
  • the barrier structures may be used in relation to, for example, stadia, sports grounds, arenas and other public enclosures, and may be permanent structures or temporary or portable structures, such as structures erected temporarily for processions, festivals, outdoor meetings or rallies.
  • the invention is primarily for use in relation to crowds of people, it might be used in relation to animals.
