Definitions

  • This invention relates to a surveillance system suitable for monitoring high risk plants and in particular the conduct of personnel in terms of safety regulations.
  • safety workers personnel are utilised to guard, observe, and take prescribed action when required, in potentially hazardous work places. These personnel monitor the environment and conditions which may pose a potentially dangerous situation for a workman.
  • the invention is concerned with a surveillance system which enables critical or hazardous locations to be monitored more effectively and at a lower cost.
  • the invention provides a surveillance system for a plurality of critical locations which includes a plurality of cameras, each camera being trained on a respective critical location, a central station, a plurality of monitors at the central station which display images from the cameras, detector devices for detecting movement at each critical location, signal apparatus responsive to the detector devices for providing a signal when movement is detected, and recorder apparatus for recording the identity of personnel entering or leaving each critical location.
  • the signal which is provided when movement is detected may be of any appropriate kind and preferably is audible.
  • the signal may alternatively or additionally be visual.
  • the signal may be provided at the location at which movement is detected and additionally at the central station.
  • the occurrence of each signal may be recorded at the central station.
  • the images which are displayed on the monitors may also be recorded and retained at least for a predetermined minimum time period.
  • Sensors may be provided at each location for detecting unwanted or dangerous events for example the presence of dangerous or noxious gasses.
  • the central station may be fixed or mobile, depending on requirement.
  • the images which are obtained from the cameras may be transmitted to the monitors at the central station using wireless techniques or by making use of cables.
  • the surveillance system may include an uninterruptible power supply which ensures that the cameras and monitors, and other power dependent equipment, can function
  • the system may include one or more mobile cameras, which are carried by personnel, and which may be used in conjunction with the aforementioned trained cameras to record images and information at any location according to requirement.
  • Figure 1 is a schematic representation of a remote surveillance station used in the system of the invention
  • Figure 2 schematically illustrates a surveillance system according to the invention
  • Figure 3 illustrates monitors used at a central station in the surveillance system.
  • FIG. 1 of the accompanying drawings is a schematic representation of a remote surveillance station 10 used in a surveillance system according to the invention.
  • the surveillance station is, in this example, provided for monitoring a vessel 12, e.g. a cylinder which normally contains dangerous liquids or gases, which constitutes a hazardous work place.
  • the vessel 12 has four manholes 14A, 14B, 14C and 14D respectively and it is assumed, for illustrative purposes, that the vessel is accessed through the manholes for maintenance or other purposes. This is given merely by way of a non-limiting example.
  • the surveillance station includes video cameras 16A to 16D which are respectively trained on the manholes 14A to 14D.
  • the cameras are connected by means of suitable cable links 18 to a remote central surveillance station 20 which is further described hereafter.
  • Each camera has a field of view which adequately covers the respective manhole and surrounding area.
  • An audiovisual alarm plug point 22A to 22D is provided at each respective manhole.
  • each manhole has a respective sensor 24 and a video plug point 26 for a roving or mobile camera.
  • FIG 2 illustrates a surveillance system 30 according to the invention.
  • the system includes a plurality of remote surveillance stations 10A 10N, each of the kind shown in Figure 1 , and a central control station or room 32 to which the remote central surveillance stations 20A 20N are connected.
  • a central control station or room 32 to which the remote central surveillance stations 20A 20N are connected.
  • use is made of wireless or cable links 34.
  • Mobile personnel 36 carry video cameras 38. These personnel are free to move within an area 40 which is monitored by the surveillance system 30.
  • the system also includes video cameras 42 which are mounted at strategic locations in the area 40 and which are remotely controllable from the central station 32. The cameras 42 can be controlled at least in pan, tilt and zoom modes.
  • the central control room 32 may be fixed or mobile. As is shown in Figure 3 the central control room 32 has a plurality of monitors 50A, 50B 50N. Each monitor is capable of displaying four images in respective quadrants of a display screen.
  • the monitor 50A is associated with the remote surveillance station 10A, the monitor 50B with the remote surveillance station 10B, and so on.
  • the images which are displayed on each respective monitor are derived from the respective video cameras 16A to 16D at each surveillance station.
  • a multi-channel time lapse video recorder 52 is located at the station and is connected to the links from the various video cameras included in the surveillance system. In this way a record is kept, for a predetermined time, of the images which are presented on the various screens.
  • the sensor 24 at each manhole detects movement around the manhole, for example a workman entering or exiting the manhole.
  • the sensor includes a buzzer or siren and, optionally, a light source.
  • an audible alarm is sounded by means of the buzzer or siren and, if required, a visual signal e.g. the light source is actuated and is caused to flash.
  • the alarm is sounded until such time as the workman in question is identified by the system.
  • each workman may carry a uniquely encoded magnetic card which is presented to a card reader 60 at the respective manhole.
  • the identity data on the card is read and is then transmitted to the remote central surveillance station 20 for onward transmission to the control room 32, for logging.
  • each workman may be given a passive transponder which is interrogated by the sensor. In this way identity data on each worker entering or leaving the manhole is automatically gathered and transmitted to a logging device 64 at the control room 32.
  • the signal which is generated when movement is detected may also be generated at the control room 32.
  • Buzzers 66 may be used to alert the workman and the control room if the entry or exit of a worker is not recorded.
  • Personnel at the central control room 32 monitor the screens 50 on which the images from the various cameras are presented. If any untoward event should occur then these personnel can initiate emergency action immediately.
  • the sensors 24 at the manholes also monitor each manhole for hazardous occurrences such as the emission of dangerous gas. Again an audible or visual alarm signal can be generated to alert personnel that appropriate action must be taken.
  • the mobile personnel 36 within the area 40 can move freely to each of the locations which are being monitored, according to requirement.
  • a video plug point 26 is provided at each location which is regarded as hazardous.
  • the mobile cameras 38 which are carried by the roving personnel can be plugged into these points to provide additional images, produced by the mobile cameras, to the central control room.
  • Radio links are provided between each remote central surveillance system and the central control room. Information produced by the various sensors, movement detectors, card readers and the like is initially collected at each respective remote control surveillance station 20, which then transmits the information to the central control room 32.
  • audiovisual warnings which are initiated at the central control room are transmitted to the corresponding remote central surveillance station and are directed to the associated remote surveillance station either to warn a workman that safety procedures are not being adhered to or to evacuate the area in question.
  • a flickering light can be used to prompt the workman to ensure that his identity data is read.
  • the audiovisual alarm plug points 22 are positioned at each respective manhole to provide a facility for the installation of warning lights and signals.
  • the system 30 is preferably powered by means of an uninterruptible power supply 70 to ensure that the monitoring function continues despite mains power interruptions.
  • the personnel at the central control room can perform the following functions: (1 ) they can continuously visually follow the adherence to safety regulations by workmen at hazardous areas; (2) they can detect when a workman fails to comply with safety procedures and, as has been pointed out, in this event a signal is also generated at the central control room; (3) they can be alerted to hazardous situations via the sensors 24;
  • the material which is recorded on the recorder 52 is kept for a specified period if no accident or potentially hazardous situation or incorrect procedures occur. Thereafter, subject to authorisation, the recorded material may be erased.
  • the material which is available at the central control room may be distributed via modem or other links to any appropriate destination.
  • a significant benefit of the invention is that the cost of monitoring a given area is significantly less than the cost which is incurred by making use of conventional techniques.
  • the surveillance takes place at a protected central control room operating conditions for the personnel involved are enhanced and the likelihood of an error occurring is reduced.
  • a complete visual and audible record can be kept of ail of the activities at each hazardous location and if an unwanted or dangerous event occurs it is possible to reconstruct the sequence of events leading up to the occurrence more accurately.
