Definitions

  • the present invention relates generally to systems and methods for controlling a transport vehicle depending on the persons to be transported.
  • the present invention relates to a system and a method for controlling the operative conditions of a means of transport, operating particularly in a closed circuit, based on prior detection and counting of the number of persons present in an area close to the means of transport and ready to use the same, keeping said persons anonymous.
  • International patent application WO-A2-2008142238 discloses a method for determining the number of persons present in a specific region or area at a specific time using an infrared thermal camera.
  • the mentioned method divides the region into a set of subregions performing calculation of the mean temperature of each subregion. It then compares each mean temperature with a reference temperature. Finally, the subregions having a value resulting from the comparison that is above a reference threshold value are multiplied by a specific coefficient expressing the mean density of the number of persons in the subregions and a Fig. showing the number of persons is obtained from the sum.
  • Patents US-B1-6,195,121 and US-B2-7,652,687 disclose other methods for calculating the number of persons present in an area, particularly in a queue in a shop, airport, concert, museum, etc., and for allowing evaluation of the waiting time in the mentioned area in this manner.
  • Japanese patent JP-B2-3405793 discloses a system for detecting pedestrians waiting to cross a zebra crossing based on images obtained by a thermal camera for configuring and controlling a traffic light (the mentioned traffic light turns green or red depending on the pedestrians waiting to cross the zebra crossing).
  • European patent application EP-A1-2541506 proposes a method and a system for managing a flow of passengers at a platform.
  • the system comprising: a detector capable of counting a number of passengers waiting at the platform; a supervision system capable of adjusting a real serving frequency and a real dwell time of the incoming public transports in function of the number of passengers.
  • US patent application US-A1-2004088104 discloses a vehicle management system that includes a vehicle location system providing location information indicative of a location of a vehicle.
  • An integrated transportation management tool is coupled to the vehicle location system and receives the location information.
  • the integrated transportation management tool initiates a course of action in response to the location information.
  • the course of action may include altering at least one of speed, capacity and route of the vehicle.
  • Passenger information may also be used by the integrated transportation management tool to determine the course of action.
  • Multiple integrated transportation management tools may be coupled by a network to provide distributed management of vehicles.
  • US patent US-B2-8942859 provides a guidance and security system for transport means, in particular complex mass transport systems, in which automatic passenger counting, security monitoring, for example, against fire, crime and terrorism, control of the use of individual elements of the transport system, such as vehicles, trains etc., automatic monitoring of the track and passenger information are connected with each other by an electronic "backbone".
  • the system comprises at least one guidance means for at least one transport means an/or for people, several recording units and a central unit.
  • the central unit is connected to the recording units and the guidance means.
  • the recording units are for determining the number of people located at a particular time and in a particular spatial area such that the central unit can control the guidance means depending thereon, in order that the appropriate number of vehicles is automatically provided with the necessary frequency and to guide passengers to the vehicle entrances.
  • means of transport preferably operating in a closed circuit (for example a ski lift of a ski station, a monorail, a tramway, etc.), the operative conditions of which are controlled (increasing or reducing its speed or frequency, modifying the number of units/cars forming it in a specific time period, etc.) depending on how full it is, for example, its access area, i.e., the waiting area accommodating the persons waiting to access the means of transport, is not known up until today.
  • the present invention provides a system according to claim 1.
  • said control unit is also connected to a regulation and/or measurement device for regulating and/or measuring the speed conditions or the number of transport units or the frequency of the means of transport.
  • the information acquisition means comprises one or more thermal cameras covering the specific area of interest, or waiting area, and the obtained digital data is one or more images in the infrared spectrum encompassing the specific area of interest.
  • the information acquisition means comprises one or more visible-spectrum digital cameras covering the specific area of interest, or waiting area, and the obtained digital data is one or more images encompassing the specific area of interest.
  • the mentioned visible-spectrum digital cameras must have a definition that is sufficient for detecting the persons but not sufficient for recognizing or identifying them.
  • the mentioned definition is preferably less than 1 pixel/cm of scene.
  • the information acquisition means comprises one or more turnstiles (or mechanical information acquisition systems) located in an area prior to the specific area of interest, or waiting area, through which the persons access the specific area of interest.
  • the means of transport is a monorail or any means of transport having similar characteristics of adjustable capacity by varying the number of units (carriages/cars) forming it (for example a tramway) in a specific time period or operative cycle.
  • the present invention also provides a method according to claim 6.
  • the first calculation further comprises calculating or estimating the waiting time of the mentioned persons in the specific area of interest.
  • the speed thereof could be varied within specific ranges comprising 3 m/s for a minimum speed value and 5 m/s for a maximum speed value (the minimum and maximum speed ranges being approximate ranges and are in no way limiting).
  • Variation of the speed of the ski lift to a minimum value would preferably correspond to the case in which there were no one waiting in the area of interest, whereas variation of the speed to a maximum value would correspond to the case in which the number of calculated persons were greater than a pre-established threshold value (e.g., more than 10 persons, 20 persons, etc.).
  • said variation to a maximum speed value would correspond to the case in which the waiting time for the persons in the area of interest were greater than a pre-established time period (e.g., 1 minute, 5 minutes, etc.), for example.
  • the mentioned dynamic modulation of the operative conditions of the means of transport is performed taking into consideration, furthermore, a second calculation based on an optimization index of the means of transport.
  • This optimization index is calculated from the first calculation and is preferably parameterizable by a user (such as an operator of the means of transport), for example, considering one or more of the following criteria: obtaining a better compromise between the waiting time and the power consumption, the availability of the number of transport units at a specific moment or time period, the need to introduce a maximum speed minutes before closure thereof, etc.
  • the processing of the obtained digital data is performed in real time simultaneously with the reception of the digital data obtained through the information acquisition means. The processing of the obtained digital data is alternatively performed after the digital data has been received, and to that end, stored in at least one memory of the computing unit.
  • the dynamic modulation of the operative conditions of the means of transport in a preferred embodiment comprises varying, i.e., increasing and/or reducing, within a parameterizable range, the speed of the means of transport proportionally to the variation of the waiting time calculated in said first calculation, the value resulting from the first calculation being transmitted by the computing unit to a control unit of the means of transport.
  • the mentioned dynamic modulation can comprise a computer dialogue with a regulation device for regulating the speed conditions, number of transport units or frequency of the means of transport, for adapting a decision concerning a change in one or more of said elements over time.
  • Fig. 1 shows a first embodiment of the system for controlling the operative conditions of a means of transport proposed by the first aspect of the invention.
  • the system includes an information acquisition means 11 formed by a thermal camera covering a specific area of interest Z close to (or near) an access to the means of transport 10, in this particular case, a ski lift of a ski station, for obtaining digital data formed by one or more images in the infrared spectrum of the specific area of interest Z, and including information relating to the persons 1 present in the mentioned specific area of interest Z, waiting to access the ski lift 10, without revealing the identity of the persons.
  • the system of Fig. 1 includes a computing unit 12 in communication with the mentioned thermal camera (through communication using wireless technology or by means of wired connection), and including at least one processor (e.g., a remote server, a PC, a laptop, a tablet, etc.) running a computing algorithm for processing the obtained digital data, i.e., for performing a first calculation of the number of persons 1 present in the mentioned specific area of interest Z.
  • a processor e.g., a remote server, a PC, a laptop, a tablet, etc.
  • a computing algorithm for processing the obtained digital data i.e., for performing a first calculation of the number of persons 1 present in the mentioned specific area of interest Z.
  • the value resulting from said first calculation is transmitted, also through any connection using wireless technology or wired technology, to the at least one control unit (not illustrated) of the ski lift 10 dynamically modulating the operative conditions thereof depending on the mentioned result, for example, increasing and/or reducing, within a certain range/percentage, the speed of the ski lift 10, without stopping it, except when the mentioned first calculation indicates the absence of persons 1 in the specific area of interest Z, for example, during a prefixed time period.
  • the percentage of variation of the speed of the ski lift 10 is done by means of a 4-20 mA analog signal acting as an input signal of the control unit of the ski lift 10. It is alternatively performed by means of a computer dialogue through a connection with a regulation and/or measurement device (not illustrated) of the ski lift 10.
  • the control unit of the ski lift 10 will automatically reduce the speed to a minimum value the ski lift can tolerate (e.g., 3 m/s).
  • the system therefore allows significantly reducing the power consumption of the ski lift 10 and the energy efficiency of the system is therefore optimized, maintaining its performances, by allowing transporting the number of persons 1 waiting for the ski lift.
  • the control unit of the ski lift 10 will automatically increase the speed to a maximum value the ski lift can tolerate (e.g., 5 m/s).
  • the system therefore allows increasing the satisfaction of the persons 1 by reducing the waiting times in the specific area of interest Z.
  • the ski lift 10 can comprise any of a chairlift system, gondola lift system, or drag lift system.
  • Fig. 2 shows a second non-claimed embodiment of the present invention.
  • the system comprises a set of thermal cameras 11 and the means of transport 10 is a monorail.
  • the system includes the thermal cameras necessary for covering, altogether, the mentioned specific area of interest Z.
  • the digital data obtained by each of the thermal cameras 10 are transmitted to the mentioned computing unit 12, and once this computing unit 12 has performed the mentioned first calculation of the number of persons 1 present in the specific area of interest Z at a specific moment and throughout a time period, this resulting value is transmitted to the at least one control unit (also not illustrated) of the monorail 10, such that the control unit of the monorail 10 can adapt, i.e., change or modify, the number of units (carriages/cars) forming the monorail depending on the resulting value received.
  • control unit of the monorail 10 could alternatively adapt the frequency thereof.
  • the control unit of the monorail 10 could even adapt both the units forming the monorail and its frequency.
  • the information acquisition means 11 is formed by a visible-spectrum digital camera with a definition having a pixel size sufficient for detecting the persons 1 in the specific area of interest Z, or waiting area, but not sufficient for identifying them.
  • the information acquisition means 11 can be a turnstile (or turnstile system) located in an area prior to the specific area of interest Z, or waiting area, where the persons 1 are present.
  • the flow chart of Fig. 3 shows a preferred embodiment of a method 300 for controlling the operative conditions of a means of transport 10 (ski lift, monorail, tramway, etc.) in which information relating to the persons 1 (without revealing their identity) waiting in a specific area of interest Z close to the mentioned means of transport 10 is obtained (step 301) by means of using at least one information acquisition means 11 formed by a thermal camera.
  • the information obtained (step 302) by the thermal camera is provided in the form of digital data comprising one or more images in the infrared spectrum to a computing unit 12 with one or more processors, and running a computing algorithm for performing a first calculation of the number of persons present in the specific area of interest Z.
  • the operative conditions (speed, frequency, number of transport units, etc.) of the means of transport 10 are dynamically controlled or modulated depending on the value resulting from the first calculation, as indicated above, suitably interacting with said means of transport.
  • the mentioned first calculation also includes calculating the waiting time of the persons 1 in the specific area of interest Z. Possible overlapping of the persons 1 in the obtained image/images will preferably be taken into account for calculating the waiting time.
  • the calculated waiting time can also be shown to the mentioned persons 1 by means of display screens/panels located in the ski station itself and/or by means of using a computer application installed in a portable computing device, for example, a smartphone.
  • the dynamic modulation can be performed taking into consideration, also, a second calculation based on a transport optimization index of the means of transport 10, calculated from the first calculation.
  • the dynamic modulation can be performed by weighing different criteria, the weights of which are parameterizable by a user/operator of the means of transport 10, for example, for achieving the best compromise between the waiting time in the specific area of interest Z and the power consumption of the means of transport 10 or due to the need to introduce a maximum speed or more carriages/cars minutes before closure of the means of transport 10.
  • the processing of the image or images in the infrared spectrum is performed in real time. Nevertheless, alternatively, the processing can be performed offline after the image or images in the infrared spectrum has/have been stored in a memory of the computing unit 12, for example.
