  With reference to these figures, we can see a telecommunication station 1 according to the invention, specially studied and designed to connect to existing world networks, regions previously kept apart because of their isolated character, or because they wind difficult to access and present rudest climate Such a telecommunication station 1 conventionally comprises at least one telecommunication pylon 8, equipped with the various antennas necessary for the reception and transmission of radio signals, as well as a room 3 in which is stored

  a series of specific radio equipment.

  According to the present invention, the telecommunication station 1 comprises autonomous supply means, such as, for example, a solar generator capable of using solar energy to make

operate station 1.

  By way of example, the solar generator is preferably designed to deliver an average power of 1400 watts, under 48 volts in direct current. It is made up of a plurality of photovoltaic panels

  4, comprising mono or poly-crystalline solar modules.

  According to a particularly advantageous embodiment, the photovoltaic panels 4 wind pilot by mechanical devices allowing their inclination, from 15 degree to 50 degree, and

from five degrees to 5 degrees.

  This inclination is a function of the positioning of the station 1 relative to the equator and allows the photovoltaic panels 4

  to store solar energy optimally.

  In addition, the solar generator also includes two redundant voltage regulators, and two compact batteries at

250OAh lead.

  These rear windshields have low self-discharge and low maintenance, and provide autonomy of the order of seven

days at nominal power.

  A DC / AC inverter converter is ready to supply the 220V alternating current necessary for the operation of the various technical devices and installations necessary for the

station operation 1.

  In addition, two control cabinets, a coupling box and a management automaton guarantee the availability of

power supply.

  It should be noted that station 1 offers the possibility of receiving, notably in the context of sites with high electrical consumption, other sources of energy supply, such as

  wind turbines or micro-turbines, for example.

  The telecommunication station 1 has a structure made up of self-supporting elements which can be joined together, light and easy to transport, in order to allow installation.

  All of the constituent elements of station 1 are prefabricated in the factory, to be deployed directly on the ground, without requiring heavy preparations, such as foundations, concrete blocks, use of cranes etc. Station 1 will, in fact, be slightly buried, between 5 and cm, after leveling the ground, and placed on a bed of raised sand

level.

  Thus, the structure of the station 1 in particular has a metal chassis 5, prew capable of supporting the pylon 2, the room 3

  and the plurality of photovoltaic panels 4.

  The chassis 5 is connected to a ground network constituted by a strip mesh and coated in the adjustment sand. At the four corners of the mesh, four ribbons of wind strip connected to the metal chfissis 5, which thus rests at the four corners on plates 8 of galvanized iron to ensure a good seat and the

adjustment of the whole.

  In addition, two other wind ribbons connected to the pyldne 2 and

  photovoltaic panels 4 in case of strong gusts.

  The pyldne 2 is made from a series of members 7 bolted together, and can have, as required, a height of 24, 30 or 36 meters, for a total weight of about 4 tonnes. Pyldne 2 is prew able to withstand strong winds, and therefore fixed on two irons of the metal chassis 5, through a

series of connection points.

  In a particularly advantageous manner, all the constituent elements of the wind structure are ready to be assembled

between them by bolting.

  Furthermore, the pylon 2 is equipped with a certain number of conventional accessories, such as in particular, GSM antennas, microwaves, work platforms 9 and work platforms.

  According to another characteristic of the telecommunication station 1, the room 3 is in the form of a compact enclosure, monobloc or coming from the bringing together of two parts. The walls and roof of the room 3 wind made from bilayer panels containing a thermal insulator, such as for example, high density polyurethane foam. They are, by

  elsewhere, covered with a sheet of pre-lacquered steel.

  It includes, in addition to conventional radio equipment, control and coupling cabinets for the solar generator,

  batteries, self protection and a remote monitoring system.

  Furthermore, room 3 is also provided with air conditioning capable of regulating the temperature as a function of the limit values accepted by the specific equipment stored, staging for example between 5 ° C. and 40 ° C., the operation of which is limited in duration during the periods sunshine

  correspond to an overproduction of the solar generator.

  According to another characteristic, the telecommunication station 1 also comprises means making it possible to set off an alarm in the event of a malfunction of the installation.

  or possible derivatives of the parameters.

  Thus, an alarm can be triggered for example in the event of a fire, in the event of detection of a battery fault, or else

  if abnormal voltage values are detected.

  On the other hand, station 1 is also equipped with access control means, such as a metal fence 12 and presence control means, such as proximity radars, connected to a

alarm system.

  All the information linked to the supervision of telecommunication station 1 can be retransmitted, if necessary, to a central remote monitoring computer, from

  so as to allow intervention on site without delay.

  As is clear from the above, the present invention allows rapid establishment of a telecommunication station 1 in previously inaccessible areas, thanks to the implementation of prefabricated means, transportable in standardized containers, two may be sufficient , by all ordinary means of transport, including the helicopter, and which can be

  assembled within a very short time with a relatively reduced cost.
