AIR TELEVIGILANCE SYSTEM AND METHOD FOR CONTROLLING AND SURVEILLING LARGE SURFACES. DESCRIPTIVE MEMORY

FIELD OF THE INVENTION

The present invention consists of a system and method of aerial televigi lancia for large surfaces, which is self-sustaining energy and capable of remotely controlling and monitoring, in real time, from anywhere and with any device with access to the network of internet, places of difficult access and that do not have a source of energy, being some of its various applications the use in agricultural operations, mining, border crossings, forestry, national parks, natural disasters, forest fires, floods, earthquakes, tidal waves, eruptions, control of causes and pollution of rivers through the use of multispectral cameras, search and rescue, massive events, road control, public and private security, or any other activity that requires the control and monitoring of large areas. It is also resistant to extreme temperatures, wind, water and allows instant access to images without requiring constant physical control. BACKGROUND OF THE INVENTION

For some years, the market for aerial televigilance or aerovigilance has had a growing irruption in applications for monitoring, control and security purposes, both at the private and governmental level, where developments have been mainly driven by significant advances in technologies related to unmanned aerial devices, audio and video recording systems, as well as telecommunications devices. Precisely, the development of these technologies has made it possible to achieve significant advances, such as the autonomy of the equipment, which are increasingly lighter, offering a better quality of operation and, above all, more economical and affordable to any type of public. unlike what happened a few years ago where it seemed that the use of state-of-the-art technology was restricted only to applications of a thousand-year or aerospace character.

Examples of the above are the increasingly popular drones whose capabilities make them suitable tools for various practical applications such as emergency services, transportation, use in agriculture, remote surveillance, etc. Precisely this last point represents one of the main applications of these devices and other unmanned aerial vehicles or UAVs for its acronym in English {Unmanned Aerial Vehicle).

In this context, drones have the advantage of offering a high displacement capacity and therefore a large field of vision, which is essential when you want to monitor or monitor large areas. However, the drones used for these purposes offer short flight periods, in the best case of 40 minutes, depending largely on the recharging of their batteries. In addition, its complicated maneuverability often makes surveillance work difficult and significantly increases accident rates, thus being considered a tool of low durability.

To try to overcome the inconveniences that drones present in televigance tasks, the Drone Aviation Corporate firm proposed a mechanism that basically consists of tied surveillance drones, where the energy for its operation is granted by a cable from the ground and therefore its movement is only ascending and descending. It also has the disadvantage that its flight autonomy does not exceed 8 hours and requires a person in charge constantly.

A device that provides greater autonomy in the air than drones are aerostats.

These devices consist of vehicles composed of a chamber that is filled with one more gas Lightweight than air such as Helium or Hydrogen, allowing it to be suspended in the air, similar to how a Zeppelin or any other type of captive balloons works. These devices are increasingly used in televigilance work as they offer long flight times, reduce accident risks compared to drones, can operate over 1 50 meters high (subject to local regulations) granting a Large field of vision and its loading capacity allows equipping them with equipment to transmit high resolution images.

An example of this type of application is disclosed in WO 2003/053346, which proposes a mobile aerial platform system comprising: an aerial platform having an outer cover, a gas containment system disposed within the outer cover , a fastening system for fixing the aerial platform to a means for transporting the system, and a payload configured to be lifted by the aerial platform when the aerial platform is inflated, where the aerial platform is configured such that It can be fully folded after being deployed.

Similarly, US 7341224 discloses a miniature balloon for a surveillance system to be used in military and public security applications with real-time observation. Video surveillance information is preprocessed and sent through wireless communication links. Batteries and / or gas cylinders can be arranged to facilitate vertical movement. The balloon may optionally have thrust mechanisms to facilitate lateral movements, which are fed by a source of combustible gas.

A drawback of the device disclosed by US 7341224 is that in order to withstand the amount of devices it carries, it requires a large volume of helium, which impairs the maneuverability of the device and significantly restricts its operation. In addition, the visual and transmission technology used at the time of this document hardly allow the use of the surveillance system in any climatic condition. Another existing limitation of this device is that although it allows access to the images registered from several points, the control is restricted to a single operations center, not allowing the control of camera functions from anywhere in the world.

An additional disadvantage of this type of televigilance aerial systems is that the hot air balloons used have low aerodynamic standards, which makes these oscillations strongly due to the force exerted by the wind, translating the above into a greater risk of accidentability and in the production of images of low quality standards.

A solution that allows providing a more efficient aerodynamic system is proposed in US 6016998, which discloses an aerial device that combines a balloon lighter than air and a kite. The aerial device comprises fixing means to secure a front portion of the kite to a lower part of the globe. In turn, the comet has a large portion of the nose while the balloon is shaped like an ellipsodie. Through this configuration the advantages of comets and balloons are collected, achieving an improved aerodynamic aerial device.

In relation to this concept, WO 2010/032251 also proposes an improved aerodynamic aerial platform which comprises a kite that provides a level of directional stability when raised by wind and an inflated balloon connected above the kite with a rope, with the payload attached to the kite. The physical separation of the balloon with the kite isolates the payload of the shocks generated by the balloon. Additionally, insulation is provided by the use of an elastic fixing cable. The electrical energy is supplied to the aerial platform by means of an optical fiber that receives power from a source located on the ground, while the conversion of the optical power to the electrical energy is carried out on board the platform. In order to provide a strong clamping line, the optical fiber is braided with a structure made of high tensile strength fibers. The aerial platform can be loaded, for example, with a camera, batteries and transmitting elements to carry out televigilance work, among others. A disadvantage of the state-of-the-art televigilance aerostatic devices is that they require access to electrical energy from the ground or be constantly lowered to the earth's surface for recharging their batteries, being unable to be energy self-sufficient and therefore involving high costs in maintenance work. In addition, they often require transmission of images through cables or optical fiber, which makes it necessary to have a nearby base station, not to mention the drawbacks associated with the weight and the range limitations resulting from the presence of said cables. Nor do they provide the possibility of being controlled by countless operators from any geographical location with access to the network

It is therefore an objective of the present invention to overcome the disadvantages of state-of-the-art devices by means of an aerial televigilance system that is energy self-sufficient, that has great autonomy, aerodynamics, elevation and that is capable of transmitting in real time. High resolution images and wirelessly to devices located over long distances, along with allowing the flight status and operating conditions of the aerial device to be known at all times.

It is another objective of the present invention to allow constant control of the air system and in particular of the functions of the camera from anywhere in the world and by means of any device with internet access.

It is another objective of the present invention to provide an aerial televigilance system with a cost of surveillance per square meter reduced, even more, 20 times less than the surveillance systems with attached cameras of the state of the art.

DESCRIPTION OF THE INVENTION

According to a first aspect of the invention, this consists of an aerial televigilance system for monitoring large areas and energy self-sufficient. This system consists mainly of an unmanned aerial unit consisting of an aerostat conformed by a hot air balloon and a comet. According to a preferred embodiment, the aerostat used is of the Helikite type, such as that disclosed in US 601 6998, which thanks to its aerostatic design is able to rise with the force of the wind and therefore lift more weight, granting more weight, granting thus a longer flight time and reducing the landing frequency for maintenance work, such as the supply of helium or hydrogen. It is also able to withstand wind speeds of up to 60 km / h, water and is made with UV resistant materials.

Advantageously, the use of an aerostat with the aforementioned characteristics makes it possible to considerably reduce the movements, granting stability in the transmitted images, greater security, less wear of moving parts and less risk of accident. In addition, it allows to reach an operating height of 1 50 meters for at least 8 days.

The aerostat is equipped with multiple compartments or pockets to accommodate the last load and has in its lower part a clamping element or "Gimbal" that acts as a device that provides stability and support to some of the elements carried by the aerostat to perform Televigilance work. Preferably, this element consists of a flat platform made of aluminum which gives the necessary resistance with a very low weight.

One of the elements that is fixed to the holding element of the aerostat is a high resolution and low weight camera. According to a preferred embodiment, a low-power motorized gyroscopic camera (18 to 30 W) is used, water and extreme weather resistant, preferably ONVIF (Open Network Video Interface Forum) standards, with optical, digital zoom and day vision and thermal night. Additionally, the camera can be configured to perform object tracking functions automatically. This quality is essential for automating the approach of a determined perimeter of so that the movements of the aerostat do not affect the perimeter recorded, thus allowing an automatic and continuous focus of the desired location.

The foregoing is also easy because the clamping element has a rocker that allows the camera to be constantly positioned and maintained at a 90 ° angle to the ground. The images recorded by the camera are sent wirelessly to a control station by means of a wireless digital transmission and reception system connected to the camera, whose transmitting and receiving elements are located in the holding element of the aerostat.

For its part, the control station is preferably located on the ground and is equipped with one or more receiving and transmitting antennas, a video receiver with a server, a digital to analog signal converter, a data transmitter, a connection device to internet and a control platform with keyboard, screen and joystick to control the specific functions of the camera and its programming from the control station.

Both the camera, the transmission and reception system and all electrical components arranged on the aerostat comply with IP Protection Degree according to protocol 1P66 and are electrically imposed by flexible anti-vandal photovoltaic panels of IP 66 protocol, preferably configured by two units located on the sides of the aerostat and one on the upper back, which are installed using tie-downs or other hooking elements such as Velero®. According to a preferred modality, the side panels are 30 W of power each and the rear panel of 100 W, also together they do not exceed 2 Kg of weight and allow generating an average daily energy close to 720 W that It is stored in batteries located in the aerostat compartments.

Preferably, two Lipo batteries are used that provide a power of 488 W each, sufficient to keep the televigilance equipment mounted on the aerostat in constant operation. Therefore, the aerostat is totally self-sufficient energy and advantageously allows it to be used in remote or hard-to-reach places that do not have sources of electrical energy. Along with the camera and the transmission and reception system, a telemetry system is also arranged on the holding element of the aerostat, which allows information about the flight status of the aerostat, such as the height, its geographical position through the incorporation of a GPS system. The telemetry system also allows to know the state of charge of the batteries in real time, is small in size and is incorporated into the video signal. All this information is transmitted to the control station wirelessly by means of the transmission and reception system, which is stored on the server.

The server is connected to an internet connection device such as a router or similar to upload information to the web where it can be requested by the user and represented in the user interface for the display of information, configuration of parameters and the motion control and camera zoom.

According to a preferred mode, the image receiver of the control station receives in a single signal the images and the camera movement function that are sent from the transmitter of the aerostat, to then be sent via an Ethernet cable to the converter signal that converts the image signal of the camera into an analog format and separates it from the motion function. After this separation, each signal is again separated in two by a "Y" cable and directed on the one hand to the control platform and on the other to a digital video recorder (DVR) with server, which stores the images with an associated IP address.

Thus, any user can access said information remotely through software and from any part of the planet that has access to the internet network. Likewise and by means of the software, the user will have access to the recordings of the camera located in the aerostat, to control the camera and to obtain the flight telemetry data. For this, the software will transmit the signal to the camera transmitter located in the control station, which in turn is received by the receiver of the transmission and reception system of the aerostat. The video and control signal of the camera provided by the software can be acquired from any appropriate user interface such as a PC, a laptop, a Tablet, a Smartphone or any similar device.

Preferably, the transmission and reception system has a range of 5 linear kilometers (between the aerostat and the control station) without the need for direct sight. However, in case this distance is not enough to find a place with internet signal, the system may comprise a satellite system integrated with the server or the incorporation of high-gain military technology antennas.

According to an alternative mode, the airborne transmission system is configured to transmit video signals and camera control along with flight telemetry directly through an internet network.

According to preferred modalities, the aerostat is raised from a lifting base, which can be a portable inflatable station or the back of a van, or any other suitable base that avoids direct contact of the aerostat with the ground. The aerostat is anchored to the ground by means of a cable wound in a winch or huinche that controls the take-off and landing manually or automatically. Preferably, the cable used is a low weight and resistant rope, made for example of Dynema® fiber.

The aerostat also has a safety device located in its front part that allows deflating the aerostat and lowering it in case of identifying abnormal movements or when an unauthorized geographical position is detected, such as more than 1500 meters from the elevation base, according to the information delivered by your gps device.

In addition, according to a preferred mode, the transmission and reception system, as well as the camera are programmed to stop working when they reach a limit of 30% capacity of the batteries, leaving the rest of the charge to the device only of security and signaling lights, giving it power for a minimum operation 72 hours before the total discharge of the batteries. According to a second aspect of the present invention, this consists of a method to control and monitor large areas remotely, in real time from anywhere and by any device with access to the internet network, using the system described above. Said method comprises the steps of:

• record images of a surface using a camera installed in an aerostat;

• obtain the flight information of the aerostat through a telemetry system;

• send the images recorded by the camera and the information collected by the telemetry system to a control station, by means of a wireless transmission and reception system installed in the aerostat;

• receive images and flight information at the control station through a receiving antenna;

• process images and flight information at the control station and upload it to the web through a server;

• access and view the images together with the flight information from the web through a user interface.

According to one embodiment of the invention, the method comprises controlling the functions of the camera from a control module of the user interface such as the zoom, focus, position and tracking of objects and paths within a given area. , activation of laser beam to mark objects, change of lens from day to thermal or vice versa, access to previous recordings, among others.

According to one embodiment of the invention, the images and flight information are sent from the control center to the user interface by means of an internet signal. According to an alternative embodiment of the invention, the images and flight information are sent from the control center to the user interface by means of a satellite Italian signal.

According to one embodiment of the invention, the instructions for controlling camera functions from the user interface are received at the control station by means of an internet signal.

According to an alternative embodiment of the invention, the instructions for controlling the functions of the camera from the user interface are received at the control station by means of a satellite signal.

According to one embodiment of the invention, the instructions for controlling camera functions are processed at the control station by means of the server and transmitted to the aerostat, where they are received by the wireless transmission and reception system.

According to one embodiment of the invention it is possible to display in the user interface additional information granted by any sensor or device, whether wind speed, temperature, radiation, pollution, date, time, or any other.

In this way, the proposed televigilance air system and method allow to control and monitor places of difficult access and that do not have a source of energy, thus having a use in various applications such as agricultural work, mining, border crossings, events massive, road control, public and private security, or any other activity that requires the control and monitoring of large areas avoiding the need to maintain physical control.

According to Figure 1, the unmanned aerial unit of the proposed televigilance system consists of an aerostat 100 formed by an air balloon 101 shaped like an ellipsoid loaded with helium and a comet 102 located at the bottom of the air balloon 101, said kite 102 being formed by a horizontal upper surface 1 03 of triangular shape joined to the lower face of the hot air balloon 102 and by a triangular vertical surface 104 as a keel located at the center of the upper surface and perpendicular to it. The aerostat 100 is made with UV resistant materials and according to the exemplification illustrated it has a volume of 34 m ³ and a load capacity of 1 4 Kg in windless conditions and 40 Kg with winds over 20 Km / hr .

According to Figure 2, the aerostat 100 is equipped with compartments or pockets 1 05 to accommodate elements such as the batteries that provide the energy for the operation of the electronic equipment, the charge controller of said batteries, the safety device for deflation of emergency and the telemetry system, said pockets 1 05 being preferably located under the upper horizontal surface 103 of the comet 102, in the upper front part of the hot air balloon 101 and in the upper face of the horizontal surface 103. In addition, certain parts of the aerostat such as the triangular vertical surface 104 of the comet 102 or the upper rear face of the hot air balloon 101 provide suitable surfaces for the installation of photovoltaic panels 1 19 (see Figures 4 and 5).

Continuing with Figure 2, it is that in the lower vertex of the triangular vertical surface 1 04 of the comet 102 a clamping element 1 10 is placed to secure certain elements that the aerostat carries to carry out the televigilance work. In particular and according to Figure 3, the clamping element 1 1 0 consists of a platform made of aluminum that has a vertical plate 1 1 1 to be supported by the aerostat 1 00 and a horizontal plate 1 12 to connect the elements to hold, both plates being joined by a rocker 1 1 3 which is connected to the horizontal plate 1 12 in an oscillating manner to allow the angle of this to be varied.

According to the modality and illustration, the clamping element 1 10 supports the wireless transmission and reception system 1 15, which consists of an IP66 protocol plastic box inside which the transmitting and receiving elements are arranged. It also has supports for the 1 1 6 antennas of said elements as well as holes for the wiring of the power supply of the wireless transmission and reception system and connection with the camera and the telemetry system. Preferably, the box of the wireless transmission and reception system 1 1 5 is adhered to the underside of the horizontal plate 1 12 of the fastener 1 1 0, for example by means of plastic straps and / or elements such as bolts, nuts , screws, etc.

Continuing with Figure 3, a high-resolution, low-weight 1 1 8 camera is fixed under the wireless transmission and reception system, for example a low-power, gyroscopic motorized camera that is resistant to water and extreme climates, with zoom Optical, digital and thermal day and night vision. The chamber is fixed to the transmission and reception system box preferably by means of clamping belts 1 1 8.

Figures 4 and 5 illustrate a preferred arrangement of the flexible photovoltaic panels 1 1 9, of which two of them are fixed to each face of the triangular vertical surface 1 04 of the comet and a third photovoltaic panel is located at the top rear of the hot air balloon 1 01. However, the location of the panels may vary, so that they are located anywhere in the aerostat 100 so as to seek a better exposure to the sun, which will depend on the winds in the area that place the aerostat in a certain direction.

Preferably, the photovoltaic panels 1 19 are installed using ties 120 and / or other hooking elements such as Velero® 121 bands. In addition, each photovoltaic panel 1 1 9 is connected by a cable 122 to the batteries located in the pockets 105 located under the upper horizontal surface 103 of comet 102. According to a preferred embodiment, the security system is arranged in the pocket located in the upper front part of the hot air balloon 101 to activate the deflation of the hot air balloon in case of identifying abnormal movements or when an unauthorized geographical position is detected.

For its part, the telemetry system (not shown) can be positioned in the clamping element 1 10, in the box of the wireless transmission and reception system 1 1 5 or in the pocket located on the upper face of the horizontal surface 103 of comet 102. Said telemetry system makes it possible to gather information about the flight status of the aerostat, such as the height and its geographical position by incorporating a GPS system, as well as the battery voltage.

Figure 6 illustrates a diagram of the operation of the proposed televigilance system, in which it is necessary that the airborne 1 00 raised in the air records images by means of the camera installed in it, which are transmitted (a) wirelessly by means of the system of wireless transmission and reception to a control center 200 located on the ground.

In the control center 200 the wireless signal emitted from the aerostat 200 is received by means of a receiving antenna 201 connected to a video receiver, a digital to analog signal converter, a server and a control platform 202, where the Information received is processed.

Once the information received from the aerostat is processed, the images are uploaded to the web and accessible by a user remotely through a user interface 400 either through an internet signal (b) 300, or through a signal (c) satellite 350.

An example of a user interface 400 is shown in Figure 7, which in the embodiment illustrated corresponds to an application for a mobile phone comprising a display module 401 for displaying in real time the images captured by the aerostat camera and a control module 402 for the user to take control of the camera and perform actions such as zoom, focus, position and object tracking. For the execution of the control actions and returning to Figure 6, the user interface 400 sends the user realized actions to the server, which are received at the control station (200) by means of a signal (b) Internet 300 or a satellite signal (c) and subsequently processed at the control center and then transmitted (a) to the air station by means of a transmitter antenna 203, where they are received by the receiver of the transmission and reception system and executed Finally in the camera.
