Definitions

  • the invention relates to a security system and in particular to a security system connected to one or more units for monitoring by an operator especially for use on a remote site, such as a waste disposal site.
  • a security system comprising a sensor for sensing an event, a control unit having at least one threat parameter for determining whether a sensed event constitutes a threat, the control unit being connected to the sensor and switchable to an alert condition from an idle condition on determination of a threat, the control unit having feedback control means whereby the threat parameters can be re-defined by an operator if the operator identifies a false threat.
  • the system can "learn" to distinguish between a false alarm and a genuine threat. That is advantageous as the system can be left to determine whether an event constitutes a threat without occupying an operator. In that way an operator can monitor systems more effectively and, as the burden on operators is reduced, more sites can be monitored by fewer operators.
  • the sensor may comprise a camera.
  • the camera may receive images in the visible light band or in the infra-red energy band. Where a camera is provided, the image received by the camera is monitored by the control unit and the control unit determines whether the image constitutes a threat.
  • the control unit processes the data from the sensor and where the sensor is a camera, the control unit preferably includes image processing means, preferably digital image processing software, to perform the evaluation of whether a monitored image constitutes a threat.
  • the senor may comprise inter alia a thermal sensor, a sound sensor, a motion sensor or a pressure pad.
  • an array of two or more sensors is provided.
  • the other sewer may be arranged to activate the camera. In that way, the other sensor can be left monitoring an area permanently and the camera is only activated when the sensor senses something unusual. That provides power saving benefits for remote units which require a self contained power supply.
  • the senor is housed in a remote unit at a remote area to be monitored and the control unit is located at a central monitoring location, the sensor being connected to the control unit by any suitable means.
  • the sensor and control unit are both housed in a remote unit at the remote location and are connected to the central monitoring location by any suitable means.
  • the aforesaid connection may be effected by a hard wire ie analogue or ISDN telephone line.
  • the connection may be a wireless connection, for instance by means of a modem and mobile telephone connection.
  • connection is preferably a hard wired connection while in the case where the sensor and control unit are located remote from the central monitoring location the connection is most preferably effected by means of a modem and mobile phone at each location.
  • the remote unit may be powered by battery power, solar power or by mains power or another suitable power source or by a combination of power sources.
  • the remote unit may include means for illuminating the area to be monitored either by visible light or by infra-red light.
  • the remote unit is preferably enclosed in a casing.
  • the casing should be sturdy and is preferably vandal proof.
  • the remote unit may include an anti-tamper device.
  • the anti-tamper device may comprise a sensor for sensing physical interference with the remote unit, for instance a trembler switch. The sensor may alert the central monitoring unit that the remote unit is being tampered with.
  • the anti-tamper device may further include an audible and/or visible alarm and, in a preferred embodiment, means for dispensing a marker substance on to a person who is tampering with the unit.
  • the marker substance may be brightly coloured or may be visible only in UV light.
  • the interior of the casing may include means for maintaining a suitable environment, for instance a heater and a de-humidifier.
  • the camera may be mounted on a movable mounting to allow the camera to scan a wider area with normal tilt/zoom capability.
  • the movable mounting may be motorised and the movement of the camera is preferably controlled by an operator at the central monitoring location.
  • the camera control may be achieved using a mirrored image and manipulation of the mirrors and/or camera.
  • the remote unit may include a position indicating device, for instance a GPS device, which indicates the location of the unit to the monitoring centre.
  • a position indicating device for instance a GPS device, which indicates the location of the unit to the monitoring centre.
  • the threat parameters may be altered manually or automatically.
  • the feedback control means includes a program, most preferably a neural net system implemented either by software or hardware which receives data from the sensor and from the operator to re-define the threat parameters.
  • Neural net software may be extremely useful in this application as it can allow the system to "learn” to recognise a threat without the threat parameters having to be understood by the operator and re-defined manually.
  • the program such as a neural net can operate on different levels of complexity of threat parameters. For instance, in an application to prevent fly-tipping, the threat parameter could simply be the detection of a vehicle which is stationary for a pre-determined period of time. In this, and other situations, the sensor unit could be programmed to distinguish general characteristics, such as humans and animals or to recognise individual characteristics such as a specified vehicle registration number using optical character recognition.
  • the remote unit may include means for allowing legitimate access to a monitored area, for instance by means of a keypad for keying in a user code or by means of a magnetic swipe card to avoid false atoms.
  • An intercom to the central monitoring unit may also be provided.
  • the sensor may detect the presence of a vehicle.
  • the threat parameter may be the presence of a vehicle.
  • the system may be equipped with a camera and optical character recognition means to log the registration mark of the vehicle.
  • the threat parameter may be a particular registration mark. For example, where particular vehicles are known to constitute a threat the system may identify the vehicle and restrict entry or, at least, alert an operative to monitor vehicle activities.
  • the entrance to the site is located some distance from the weighbridges which are located within the site. Accordingly, there is usually some time between the vehicle entering the site and the vehicle passing over the weighbridge.
  • the weighbridge can be by-passed by the vehicle driver or the weighbridge operator can allow the vehicle over the weighbridge without logging the weight in order to avoid payment of the charge for depositing the waste.
  • the security system can be arranged at the entrance to a waste disposal site and vehicles entering the site can be identified.
  • the threat parameter in that case could be the entry of the vehicle, the identity of the vehicle, or a time limit from entry of the vehicle to its departure. Further threat parameters such as an unexpected difference in vehicle weight between entry and departure or the identity of the vehicle load are also envisaged.
  • the system includes a camera and optical character recognition means, the system can be arranged to recognise the load identification signs carried by haulage vehicles and to alert an operator if certain load types, such as noxious chemicals, are detected.
  • the control unit may also associate details of a transaction conducted in relation to the vehicle within the site with the registration of the vehicle. If an incorrect transaction is noted an operator can be alerted.
  • a vehicle logging system comprising a camera for recording an image of the registration mark of a vehicle entering an area, optical character recognition means for identifying the vehicle registration mark from the image recorded by the camera and a control unit which associates details of a transaction conducted by the vehicle within the aforesaid area with the registration mark of the vehicle.
  • a sensor may be provided to activate the camera, the sensor sensing passage of the vehicle through the entry to the area.
  • the sensor may be pressure pad or a light sensor.
  • the optical character recognition means preferably comprises a computer with image processing software and optical character recognition software.
  • the computer preferably also comprises the control unit.
  • a security system comprising a sensor for sensing the presence of a vehicle, a camera activated by the sensor when a vehicle is sensed for recording an image of the registration mark of the vehicle, optical character recognition means for identifying the vehicle registration mark from the recorded image and a control unit which associates details of a transaction conducted in relation to the vehicle with the registration mark of the vehicle, the control unit including at least one threat parameter for determining whether an event related to the vehicle constitutes a threat, the control unit being switchable from an idle condition to an alert condition on determination of a threat and the control unit having feedback control means whereby threat parameters can be redefined by an operative if a false threat is identified.
  • the logging system is used in combination with a weighbridge.
  • the system may comprise a camera at a controlled access point, such as the entry to the site and a camera or cameras at each weighbridge on the site, each camera recording an image of the registration of the vehicle and passing the image to optical character registration means for identifying the vehicle registration mark.
  • the system includes sensors for detecting whether the vehicle is aligned correctly on the weighbridge.
  • the sensors may comprise light sensors or pressure pads.
  • image processing means may be provided to process the image from the camera at the weighbridge to further determine correct alignment of the vehicle on the weighbridge. In some circumstances, it is possible to reduce the charge levied for disposal of waste by incorrectly placing the vehicle on the weighbridge.
  • the weighbridge For example, by leaving the back wheels of the vehicle off the weighbridge a proportion of the weight of the vehicle is not supported on the weighbridge and thus the vehicle weight will be under measured.
  • the sensors and image processing means are intended to prevent such fraudulent activity. In that way fraudulent use or avoidance of the weighbridge altogether can be detected.
  • a weighbridge operator presses a button on the weighbridge control to cause a weight measurement to be forwarded to a transaction printing system.
  • the operator also enters the vehicle details including the vehicle registration number to identify the vehicle and associate it with a transaction.
  • the camera at the weighbridge reads the vehicle registration number and compares it with the details entered by the operator. If any discrepancies occur then the image recorded by the camera, together with the transaction details are transmitted to a remote site and, if necessary, are brought to the attention of the site operator.
  • two cameras are provided at the weighbridge, the cameras being arranged to view the edges of the weighbridge.
  • the cameras together with appropriate image processing software in the control unit can check for incorrect alignment of the vehicle on the weighbridge, record the vehicle registration information by optical character recognition software and the details of the fraudulent transaction and vehicle details can be passed to an operator at a remote site. The operator can then determine the appropriate action required. Such action might be to require the vehicle to be weighed again or to report the fraudulent transaction to the site operator.
  • the logging system is preferably connected to the remote site via a modem and mobile telephone connection but any appropriate data transfer equipment such as ground telephone line or direct hard-wired connection can be used.
  • One of the cameras or a further camera can be arranged to view the sign on the vehicle which indicates the nature of the goods carried and the control unit can be arranged to recognise that data and make an appropriate log.
  • a timer may be provided to detect the time a vehicle takes between entering the site and reaching the weighbridge. If a vehicle has not reached the weighbridge a pre-determined time after entering the site then the vehicle may have taken a detour to avoid using the weighbridge. An alarm can be raised by the control unit to alert the site operators of that possibility.
  • a camera may be provided on the exit to the site, again to determine whether the vehicle has been weighed on exiting the site and to ensure that all vehicles that have entered a site on a particular day have left.
  • the system will allow operation of a weighbridge at a site, such as a landfill site, without the need for a weighbridge operator.
  • the type of load carried by the vehicle onto the site in the case of waste disposal, or off the site in the case of a quarry site will, in conjunction with the weight of the load, determine the transaction price. This is best identified by a person at the point of loading or unloading who, with a suitable mobile computer unit may enter the load type identification for inclusion in the transaction record. The entry of the vehicle to the site will be logged as previously described. The correct inbound weight is verified as previously described.
  • the control unit will transmit the initiated transaction to the remote operator at the loading or unloading area of the site. When this operator enters the load type identification, this information is transmitted back to the control unit which, when followed by a verified outbound transaction, will allow the automatic production of a transaction ticket, for collection by the driver before leaving the site.
  • the control unit may include a memory area for exempted vehicle registrations, such as visitors cars etc.
  • a vehicle logging system comprising a first camera for recording an image of a registration mark of a vehicle on entering an area, optical character recognition means for identifying the vehicle registration mark from the image recorded by the first camera, a second camera for recording an image of a registration mark of a vehicle on exiting the aforesaid area, optical character recognition means for identifying the vehicle registration mark from the image recorded by the second camera and a control unit which records the time between entry of the vehicle to the area and exit of the vehicle from the area.
  • a ticketless car parking system whereby the exact time that a vehicle has been in a car park can be recorded and charged for, or by the same identifying means, access to an area such as a car park can be restricted to authorised vehicle numbers only, without the need for keys, swipe cards etc.
  • control unit can provide an alert where a vehicle has been within the area longer film a predetermined amount of time, say 24 hours. In such a circumstance, the control unit could alert the car park attendant and/or the emergency services.
