Definitions

  • This invention relates to a motion sensitive system, and in particular to a motion sensitive system which generates a control signal when a target is validly approached. This invention further relates to a method of generating a control signal.
  • Automatic doors generally comprise one or more doors attached to an electrically operated door opening mechanism which either swings or slides the door open.
  • Automatic doors further include a proximity sensor, usually an infrared sensor or a microwave radar sensor. These proximity sensors will generally monitor an area in front of the door and if the sensor detects a person entering the area, a control signal will be sent to the door opening mechanism which will then open the door.
  • a motion sensitive system that generates a control signal when a target is validly approached by a moving object
  • said system comprising: a sensor arrangement which captures a plurality of images of a moving object, moving in proximity to the target; a processing module arranged to perform image recognition, the processing module receiving the plurality of images from the sensor arrangement and calculating the velocity of the moving object before referencing the velocity of the moving object with a predetermined threshold; wherein the processing module is also arranged to generate a control signal in response to the calculated velocity satisfying a predetermined criterion with respect to the predetermined threshold.
  • a method of generating a control signal when a target is validly approached by a moving object comprising the following stages: a sensor arrangement captures a plurality of images of a moving object, moving in proximity to the target; a processing module, which is arranged to perform image recognition, receives the plurality of images from the sensor arrangement and calculates the velocity of the moving object before referencing the velocity of the moving object with a predetermined threshold; and the processing module generates a control signal in response to the calculated velocity satisfying a predetermined criterion with respect to the predetermined threshold.
  • Automatic doors generally have an electrically driven motor to operate them and further include proximity sensors as described above, mainly utilising infrared or microwave radar.
  • the present invention may utilise these drive motors, and work in conjunction with the pre-existing proximity sensors.
  • the motion sensitive system may further include a proximity sensor, and the proximity sensor may be an infrared sensor or a microwave radar sensor.
  • the opening mechanism will only be triggered if a control signal is received from both the proximity sensor and a motion sensitive sensor.
  • a motion sensitive system could be the only system used to trigger the opening of the door.
  • automatic doors could be produced which incorporate the motion sensitive system, the system could also be retrofitted to pre-existing automatic doors. Whilst the present application could apply to the automatic doors of a building, it could also apply to automatic doors on a vehicle such as a bus or a train.
  • temperature sensors linked counting means could be provided on the inside and outside of the door to calculate the temperature difference between each side of the door. By counting the number of times that the opening of the door by the proximity sensor had been inhibited by the motion sensitive system, an energy saving can be calculated based on the temperature difference. Temperature sensors could also be used to calibrate the motion sensitive system so that it is less sensitive (and as a result the door is less likely to open) if there is a greater temperature difference between the outside and inside of the door, for example during the winter, than if the difference in temperatures were smaller.
  • the signal generated could operate an alarm.
  • the sensor arrangement can be deployed to monitor the blind spot of a lorry. If a cyclist, for example, pulls into the blind spot, its motion into the blind spot would be sufficient to trigger the alarm and notify the driver that the cyclist was there.
  • any means which can detect the velocity (velocity being understood to mean a vector of the speed and direction) of the moving object could be used as the sensor arrangement, though for most practical purposes, such as when applied to automatic doors or escalators, the sensor arrangement may comprise a video camera, for example a web-camera. Web-cameras have the further advantage of being cost effective for day to day use, which is particularly important considering that many such systems according to the present invention could be used within a single premises.
  • the sensor arrangement could also comprise one or more infra-red camera, which can help to distinguish between people and inanimate objects should this be required.
  • a motion sensitive system including an infra-red camera might reduce the number of false openings by only opening when a person approaches the door.
  • other sensor arrangements such as ultrasound could conceivably be used. Whilst a single camera will generally be used, it has been found that in certain circumstances multiple cameras linked together provide an increased field of vision. For example, two linked cameras will be preferable for identifying one person positioned behind another, or if there is an unusual door layout.
  • the processing module receives information from the sensor arrangement which it analyses to see if relevant motion is detected. In order to do this, the processing module contains image recognition software which tracks the movement of the moving object. Image recognition software that can track the motion of an object is known per se, for example as provided in EP0567059 or EP0474307, and software such as this could form the basis for the software used by the processing module of the present invention.

  • the processing module may be arranged to generate a control signal in response to the calculated position and velocity satisfying a predetermined criterion with respect to the predetermined positional threshold.
  • the positional threshold may comprise two or more data (more than one datum), for example in the form of virtual markers arranged substantially perpendicular to how the moving object would normally approach the device. A signal could then be generated if the moving object passes two or more data within a certain time period.
  • the data In the case of an automatic door, the data would be positioned in parallel with the doorway and spaced apart from each other, and in the case of an escalator the data would be also parallel and spaced apart in front of said escalator.
  • the trajectory of a person approaching a door would be different to that of someone simply walking past. Therefore the data will be arranged so that they would only be crossed within a particular time frame by a person who is approaching the door.

  • the threshold could comprise one or more data, for example in the form of virtual markers, arranged substantially in line with how the moving object would normally approach the target.
  • the data could be drawn physically on the ground and recorded by the image recognition software, or alternatively could be defined in software.
  • the system may then continue to detect the motion, and when no more relevant motion is detected towards the door for a predefined period of time, the closing mechanism is triggered.
