Abstract

The present invention relates to a system for detecting environmental and operating data about a helisurface, which is adapted to detect information (images, meteorological conditions, air traffic and obstacles on the monitored helisurface and in the surrounding space) by using innovative detection devices, each of them comprising a single waterproof case (1) where a plurality of detectors (7,8,9,10) is housed.

Description

Detection system of environmental and operating data relevant to a helisurface.

The present invention relates to a system for detecting environmental and operating data about a helisurface.

In this description and in the attached claims, the term "helisurface" is used to indicate an air surface for exclusive use of helicopters pursuant to section 1 of the Ministerial Decree dated 10 March 1988.

In aviation it is crucial to know the environmental data of helisurfaces in real time to program a flight.

This data refers to variables that intervene during helicopter piloting and allow the pilot to make take off and landing maneuvers correctly or prepare the helicopter in such manner that the various flight phases are carried out safely until destination.

For instance, such data refers to physical and environmental conditions (meteorological and visual conditions), temperature, humidity, atmospheric pressure, wind speed and direction, dew point, or other conditions, such as air traffic in the space surrounding the helisurface.

Currently, in order to detect said data, the pilot uses a control center (generally situated in the airport closest to the destination helisurface, often many kilometers away from the latter), which receives data from a plurality of detection devices installed in said control center.

Data is transmitted orally by the control center to the helicopter pilot, who uses it in the various piloting phases of the helicopter.

Such a situation is impaired by several inconveniences: the pilot must communicate with the control center to request data, the control center must acquire, check and transmit data to the pilot, with a sequence of operations that may be long and complicated and is not very suitable for emergency situations (for instance, reference is made to a rescue helicopter landing on a far-away helisurface) or during radio transmissions with strong interference that may cause misunderstanding during the oral data transmission to the pilot.

Another inconvenience refers to the fact that the control center is not able to determine the presence of other helicopters or obstacles of other kind on the destination helisurface, which can jeopardize the helicopter's safe landing. An additional inconvenience is given by the fact that, compared to an airport runaway, objects (wind sleeve, entrance gate, surrounding trees, pylons, etc.) are present in the proximity of the helisurface, with variable position between different helisurfaces.

A further inconvenience consists in the fact that helisurfaces used for rescue purposes are often installed in places that are not easily accessible and therefore the installation of a plurality of detection devices in the proximity of said helisurfaces involves additional problems due to complex installation and maintenance of each device.

Moreover, it must be noted that, unlike airports where sequences of take offs and landings of aircrafts are scheduled daily, helisurfaces are used with unexpected and irregular frequency.

The system of the invention has been devised to overcome the inconveniences and limitations of the state of the art, as illustrated below with reference to some of the most representative patents of the prior art. Patent US7019637 discloses a system and method for detection, analysis and interpretation of environmental data detected in an enclosed area, which is processed and sent to a remote computer for consultation through different types of communication lines.

In such document the detection modules (which consist in data acquisition units) are connected to a plurality of sensors that are difficult and uncomfortable to maintain, being far-away from the detection module and in any case external to the box used to house and protect the detection module.

The invention of patent US7019637 does not provide for alert devices that can be actuated by the detection modules installed in the helisurface to communicate from the helisurface with the pilot during the flight (through a satellite communication), with the operating center or with any other telephone number, or receive calls on the helisurface from predefined users (for instance, an operating station that wants to inform an alert status to people on the helisurface).

Patent US 6154143 relates to a portable meteorological information system. The invention disclosed in patent US 6154143 exclusively provides for using radio frequency communication between the portable terminal and the data detection center; in view of this, the pilot can consult meteorological data only and exclusively when he is in the proximity of the helisurface, and not before taking off in order to decide whether to fly or not, and of course not during the flight. The invention disclosed in said patent does not provide for using IP communication of satellite, mobile and terrestrial type, therefore, should these systems be installed in remote areas where radio signal is not present (for instance, oil platforms) they would not be able to communicate. Patent US 5323649 relates to a wind direction and velocity indicator for airports.

The device disclosed in said patent is only and exclusively used to detect wind velocity and direction, whereas no sensors of other type are provided. Patent EP 2124213 relates to a system collecting data about spatial objects and providing services.

Like in all the aforementioned patents, this patent is impaired by the following limitations:

a) lack of devices that allow the helicopter pilot to view clouds, fog or the presence of obstacles in the proximity of the landing lane (before and during take-off).

b) lack of self-diagnosis systems of sensors provided in the aforementioned devices; in view of this, the pilot is not able to detect the correct operation of the sensors at any time, and especially before take-off; c) the pilot is not able to actuate from remote (even before take-off) any device situated in the proximity of the helisurface, such as for example lights or access gates in the helisurface; d) lack of alert devices that can be actuated by the detection modules installed in the helisurface in order to communicate from the helisurface with the pilot during the flight (through a satellite or GPRS communication), with the operating center or with any other telephone number, or receive calls on the helisurface from predefined users (for instance, from an operating station that wants to inform an alert status to people on the helisurface).

e) no use of other communication except for radio communication, including satellite communication through providers such as, for example, Iridium or InMarSat in such manner that, if these known systems are to be installed in areas with no radio signal (for example, oil platforms), they will not be able to communicate.

The purpose of the present invention is to devise a system for detecting environmental and operating data about a helisurface, which is able to overcome the aforementioned inconveniences.

Such a purpose is achieved with a detection system according to the attached claim 1.

Another purpose of the present system is to check, in helisurfaces with or without supervision, whether helicopters have been authorized to land in the helisurface.

Another purpose is to devise a system that allows users to rapidly make payments to the helisurface provider in order to obtain services for landing or refueling.

The idea of the present invention is to devise a system able to detect information (images, meteorological conditions, air traffic and obstacles on the monitored helisurface and in the surrounding space) thanks to the use of innovative detection devices, each of them comprising a single waterproof case where a plurality of detectors is housed.

Hence, installation and maintenance are advantageously simplified, it being simply necessary to take action in only one common area for all detectors housed in the same detection device. The idea of the system according to the present invention is to allow for using data detected by one or more detection devices simultaneously through consultation of a remote terminal.

Advantageously, the remote terminal is of portable (not fixed) type and can be transported by the pilot or aircraft crew in such a way to know directly the environmental data (meteorological and visual data) detected by the detection device of the helisurface where the pilot intends to land at any time, before and during the flight, through satellite and/or mobile communication, in case of an emergency that forces the pilot to land in a helisurface outside of the scheduled route also without the intervention of the control center.

In such a way, data detected by the detection devices installed in the helisurfaces, which is necessary for correct maneuvers or flight, is available at any time to the pilot or more generally to the aircraft crew.

Such a characteristic is extremely advantageous in emergency cases where the flight is not scheduled in advance; reference is made, for example, to helicopters engaged in rescue operations, when they must operate rapidly and quickly in difficult conditions (at night or in bad weather conditions).

Other characteristics and further advantages will become clearer after illustrating an embodiment of the invention with reference to the enclosed drawings, wherein:

- fig. 1 is a front view of the detection device used by the detection system of the invention;

- fig. 2 is a side view of the detection device of fig.1 ;

- fig. 3 is a rear view of the detection device of fig .1 ;

- fig. 4 is a diagrammatic functional view of the detection system of the present invention;

- fig. 5 is a power board mounted in the device of fig. 1 ;

- fig. 6 is a main board mounted in the device of fig. 1 ;

- fig. 7 is a sensor board mounted in the device of fig. 1 ;

- fig. 8 is a diagrammatic functional view of the detection system of the present invention according to a preferred embodiment. Figs. 1 , 2 and 3 illustrate one of the detection devices (1 ) provided in the system according to the present invention.

The device (1 ) comprises a stand (2) where a case (3) is mounted, housing detectors of environmental/meteorological and/or visual and operating data about a helisurface.

The device (1 ) is adapted to be mounted on the edges or in any case in the proximity of a helisurface (H), shown in fig.4.

Going back to figs. 1-3, as shown in the example, the case (3) is waterproof so that it can be mounted outdoors, and comprises the following detectors: - anemometer (7), preferably of ultrasound type;

- barometer (8);

temperature and/or humidity detector (9);

- rain gauge (10);

Such detectors (7,8,9,10) are of known type and therefore are not illustrated in detail, referring to specialized literature for further information on their characteristics or operation.

Obviously, it must be noted that alternatively, according to the type of use or installation place, embodiments can be provided with more or less detectors (7,8,9,10), also of different type.

Such device (1 ) optionally comprises apparatuses able to maintain the internal operating temperature of electronic components within an ideal operating range.

The aforementioned detectors (7,8,9,10) are operatively connected to a processing unit (not shown) housed in the case (3).

The processing unit can be provided with memory means and means to check data coming from detectors (7,8,9,10).

Said processing unit possibly can store said data and/or uses it to calculate data derived from it (such as dew point, statistics on rainfall, atmospheric pressure trend, etc.).

Advantageously, as shown in the example, the case (3) also houses the following accessories:

- a light indicator (11 ); - a waterproof microphone/loudspeaker (5);

- a call button (4);

- a camera (6), preferably a high night sensitivity

anti-glare camera;

- a sound indicator (13);

- one or more solar panels (14);

- a POS terminal (not shown in the attached figures).

Preferably, both the case (3) and stand (2) are made of fiberglass, with approximately 2 cm thickness and total height of approximately 180 cm, in such manner to be light and sturdy, adapted for outdoor installation and resistant to adverse weather agents and conditions.

Fiberglass has been chosen because, unlike steel and other ferrous materials, it does not transmit external temperature variations to components housed in it.

More precisely, as shown in the example, the case (3) has only one opening and is covered with only one panel.

A radio beacon can be provided in said case (3).

Preferably, the stand (2) and case (3) are completely made of fiberglass, in various parts that are mutually joined with resin welding process, with two main advantages: considerable reduction in the weight of the structure (thus making transportation easier) and lack of exposed metal parts to avoid system grounding.

Solar panels (14), which are operatively connected with a pack of electrical batteries (not shown), are designed to power the device (1 ) and/or sensors (7,8,9,10) and/or accessories (4,5,6,11 ,12,13) also without power from the mains, in such manner to install the device (1 ) also in helisurfaces situated in remote positions, where no electrical power mains is available (reference is made, for example, to mountain helisurfaces for alpine rescue services). The device (1 ) comprises at least three elements; an input/output matrix management system, a matrix communication system interfaced with transmission devices (such as GSM/GPRS router, satellite, radio, RS232 or similar) and a GPS position detection system. As regards the practical realization of the electronics inside the device (1 ), fig. 5 shows a power board (40) operatively included in the latter.

Such power board (40) comprises ports for connection with a battery charger (41 ), connectors for connection of internal devices (42), a first slot (43) for connection with a main board of the device (1 ), an adapter for a LAN line (44), inputs (45) for external sensors and outputs (46).

Moreover, the board (40) comprises fuses (47) and volume control for loudspeaker (48).

The device (1 ) also comprises a main board (50) shown in fig. 6, operatively connected to the slot (43).

The main board (50) comprises two ports (51 ,52) for connection and control, for example, for debug or error removal (51 ) and firmware update (52).

Advantageously, the main board (50) also comprises a displacement sensor (53) with anti-vandalism function, a second slot (54) for connection to said first slot (43) and a housing for a SIM card (55), for example to allow for data connection with telephone lines.

Finally, a microphone (56) is connected on the main board (50).

Advantageously, the device (1 ) comprises a sensor board (60), shown in fig. 7, comprising a multipolar connector (61 ) and ports (62) for connection of acoustic/visual alarms, in such manner that all sensors can be connected to the same point, i.e. the sensor board (60).

This ensures high compatibility with most meteorological devices available on the market, together with great versatility in the choice of communication methods, such as:

· GSM\GPRS

• UMTS\HSDPA

• Local LAN

• Satellite (Iridium, InMarSat, etc.).

Advantageously, the device (1 ) can be automatically activated by using information on the position of the helicopter and/or the expected arrival time. Advantageously, the "communication module" (12) is of the type adapted to transmit signals of both GSM and GPRS and Edge (E-GPRS) and UMTS and satellite (Iridium, InMarSat, etc) type, in such manner to send or receive data processed by the processing unit or received from the detectors (7,8,9,10) and/or accessories (4,5,6,11 ,12,13) over a communication line (L1.L2) according to different modes that are known in the prior art and therefore not further illustrated herein.

Accessories (4,5,6,11 ,12,13,14) also comprise a camera (6) for detecting images, preferably the camera (6) being of Mpx type with anti-glare device and optical zoom, high night sensitivity and recording images in screen shot (not continuous) mode, thus optimizing the use of the communication line. An advantageous characteristic of the device (1 ) is that it also allows for direct communication between the operator of the device and a control center (18).

For such a function, the waterproof microphone/loudspeaker (5) and the call button (4) indicated above among the accessories are used. Such a function can be useful whenever the operator is situated near the device (1 ) and needs to inform anomalies (on the helisurface or the surrounding area) to the control center (18) or to an emergency unit by means of the communication line (L1 ) shown in fig. 4.

Another advantageous characteristic of the present invention is that the device (1 ) is connected to the lights of the helisurface where it is installed and controls switch on or off according to a command, in order to switch on landing lights at night by sending a command signal to the device (1 ).

Such an operation is made via software, and therefore not only in the proximity of the helisurface, but also during the flight and from any distance. Another peculiarity of the system is that the device provided with transponder is able to locate in real time the position of the aircrafts in the proximity of the device and transmit it to remote terminals (either fixed or mobile), especially in low-level flying situations (i.e. gorges, valleys) through radio transmitting- receiving systems compatible with the main standards provided on board the aircrafts.

Another innovative characteristic of the present invention is that, through the installation of a detection sensor of known type, the device (1) can acquire identification codes of helicopters landing on the helisurface where the device (1 ) is installed. Because of the presence of said detection sensor of identification codes, the device (1 ) can check whether the helicopter is authorized or not for landing.

Moreover, the device (1 ) is provided of a terminal of POS type (not shown in the attached figures) used to make payments for services offered by the helisurface provider (landing, refueling, etc).

Advantageously, referring to fig. 4, the system according to the present invention also comprises, in addition to the aforementioned device (1 ), a portable remote terminal (15) provided with a display means (16) such as a screen and data input means (17), such as a keyboard.

The portable remote terminal (15) simultaneously communicates in bidirectional mode with one or more devices (1 ) in such manner to receive in real time data detected and/or calculated by it (as illustrated above) through communication line (L2).

The portable remote terminal (15) can be given to the pilot or the aircraft crew to consult or receive directly data detected or calculated by the device (1 ) without having to contact the operating center (18), thus making the operation quicker.

Obviously, a portable remote terminal (15) can communication with one or more devices (1 ) of the type illustrated above, in such manner to provide the pilot or aircraft crew with detection data and allow for choosing the flight plan or the use of a specific helisurface (H) according to such data (i.e. to land on a helisurface (H) with more favorable meterological-environmental conditions).

Moreover, in case of a bidirectional communication line (L2), the remote terminal (15) can be used by the aircraft crew to switch on the lights of the helisurface (H), in case of night use or poor visibility, and/or to communicate with the operator using the device (1 ), for example to coordinate rescue operations. In actual fact, each device (1) comprises a "communication module" (12) to send data through the management unit to the remote terminal ( 5) and/or to the operating center (18);

Amongst the advantages, the pilot can actuate the acoustic (13) and/or light (11 ) indicator to inform about the forthcoming arrival of the helicopter.

Advantageously, the communication line (L2) comprises different types of communication lines and possibly comprises a section of the Internet.

For instance, the communication line (L2) comprises a first and a third GPRS or satellite communication section and an intermediate communication section over the Internet.

In such a case, the device (1 ) communicates through a mobile network (for example, through GSM/GPRS or satellite), with a Web portal to transmit calculated data and/o data detected by detectors (7,8,9,10) and accessories (4,5,6,11 ,12,13).

Through the remote terminal (15) access is provided over GSM/GPRS or satellite to said Web portal where data of one or more devices (1 ) is available in real time.

Numerous variations can be made by an expert of the field to the communication lines (L2) and are to be considered as the object of the present invention.

The device (1 ) also communicates, through communication line (L1 ). with an operating center (18) informing data detected and transmitted by the devices

(1 )·

The characteristics of the communication line (L1 ) are identical to those illustrated for communication line (L2) and therefore no further information is provided herein.

The system of the present invention also comprises a plurality of devices (1 ) as illustrated above, connected in a network to a Web portal that can be accessed through a computer or remote terminal (15) in such manner to allow users to display the data detected by the detectors of each device (1 ), and display images of the helisurface where each device (1 ) is installed. Fig. 8 shows an alternative embodiment of the system according to the present invention.

The system comprises:

- one or more devices (1 );

- one or more portable remote terminals (15);

- one or more operating centers (18);

- one operating station (20) connected to a data storage server (19).

The system of the invention provides that said operating station (20) acquires in real time information (images, meteorological conditions, air traffic and any obstacles in the area surrounding the monitored helisurface) from the devices (1 ) to store it in the server (19), in such manner to make it simultaneously available to one or more portable remote terminals (15) and to one or more operating centers (18), after processing it and making it available through a software application exclusively designed for operation of rotary wing aircrafts (helicopters).

Moreover, before flying to an unknown landing area, the system allows the helicopter pilot to analyze a pre-recorded 360° video sequence of the area surrounding the destination helisurface, in order to evaluate the safety of take-off and landing conditions in such helisurface.

The system also comprises a software application that, after entering the departure and arrival points of the mission, calculates the ideal route according to the information provided by the devices (1 ).

More precisely, after the pilot has entered the departure and arrival points of the mission, he will automatically receive the ideal route according to meteorological conditions, air traffic and possible obstacles in the area surrounding the helisurfaces situated in the proximity of the air distance between departure and destination place.

The software application allows for optimizing the selection of routes made during emergency missions with helicopters, thus increasing the safety factor. Through said system the pilot will receive information, not available so far, that will indicate the ideal route after analyzing the parameters of the set route.

In other words, the above will avoid aborted missions due to variations in progress of the meteorological parameters and therefore increase the safety of flights in medical and civil protection emergency missions.

Moreover, the centralized management system allows for accessing the same device and analyze the meteorological and visual conditions on the same helisurface from several terminals simultaneously.

Consultation can be carried out both on meteorological and visual data in real time and on historical data stored in a dedicated server, which can be used at any time.

Through the centralized sensor control system the status of detectors (7,8,910) and accessories (4,5,6,11 ,12,13,14) of one or more devices (1 ) is always available in real time although they are installed in helisurfaces without supervision.

The system is provided with a self-diagnosis apparatus (not shown in the attached figures) that constantly monitors the operation of sensors and devices, detecting possible anomalies in such manner to inform the pilot in real time about the functional situation of the devices (1 ).

In summary, the system for detecting environmental and operating data about a helisurface according to the present invention has the following advantages:

a) real time detection of images, meorological conditions, air traffic and obstacles in the area surrounding the monitored helisurface;

b) before flying to an unknown landing area, the helicopter pilot can analyze a pre-recorded 360° video sequence of the area surrounding the destination helisurface, in order to evaluate the safety of take-off and landing conditions in such helisurface.

c) automatic determination of the ideal route to be sent to the pilot, according to meteorological conditions, air traffic and possible obstacles in the area surrounding the helisurfaces situated in the proximity of the air distance between departure and destination place;

d) by means of the help button, the operator in the proximity of the device (1 ) can inform the control center (18) or any emergency unit, through the dedicated communication line (L1 ), about anomalies occurred in the helisurface or the surrounding area;

e) inform the pilot in real time, through a self-diagnosis apparatus that constantly monitors the operation of sensors and devices, detecting anomalies, about the functional situation of all devices (1 ) included in said tele-monitoring system.

Further variants can be applied to the aforementioned precepts, such as different types of detectors, communication lines, functionalities, etc., which are to be all considered as an integral part of the present invention.
