Abstract

Access control system to wind towers. The system allows to control through a control center (8) the access to the different wind towers of the different wind farms associated to said control center (8), for which, each door or access of each wind tower includes a electronic lock (3) that is associated with a control circuit (5) connected to a conventional (6) or satellite (7) communications module for the registration and remote control of access from the control center (8), said control circuit (5) including means of identification and validation/rejection of access for the operators.

Description

DESCRIPTION

Access control system to wind towers

TECHNICAL SECTOR

The present invention refers to an access control system in wind towers or wind turbines, the obvious purpose of which is to replace the conventional key and cylinder access system with all the problems that it may cause (loss of keys and non-control of people who enter, robberies, vandalisms, ...) and that of allowing to control and regulate access to the aforementioned towers and their different areas, so that, in person or from a command center or control center, it can be programmed its opening electrically, mechanically or electronically, so that in case of need a particular access code for maintenance personnel is attached, which can be from a simple card, CHIP, RFID, a Smartphone, biometric devices, or simply a opening by means of the traditional audio pushbutton with opening response, video intercom, etc.

The object of the invention is therefore to control all accesses, so that in park, etc.) all the information is available on who and at what time they enter, which areas they access and when they leave, thus controlling those responsible for each repair or incident.

The system will allow access to the interior of the ground floor, the control panel, the elevator, etc.

BACKGROUND OF THE INVENTION

At present, access to the interior of the wind towers is carried out through the traditional opening of the doors with a mechanical key, so that there is no regulation regarding the control of the keys, producing different situations that delay access to the towers, causing delays in repairs and maintenance, as well as allowing free access to whoever has the key without having control of said accesses.

Although there is currently a control center for each manufacturer and / or developer of wind towers, from which the status of all the wind turbines of the different wind farms attended by said manufacturer and / or developer is controlled, in a way that To date, and as stated, when managing these incidents, a repair and maintenance team is sent to the tower in question, sometimes leading to significant delays in collecting or locating the keys.

EXPLANATION OF THE INVENTION

The system that is recommended solves in a fully satisfactory way the previously exposed problem, based on a simple but effective solution, allowing to minimize the action and response times, as well as having a rigorous control of the accesses and time of stay in each one. of the wind towers.

For this, and more specifically, both the primary access door of the wind tower, as well as the different access doors to the different compartments or modules of the wind tower will be assisted by an electronic lock associated with a control circuit connected to a satellite communications module (or the means of connection that each manufacturer or developer has) with the corresponding control center, so that access to the different modules of the wind tower can be managed in real time in said control center, either through an RFID card reader, an identification interface or through the remote control corescentre and in real time allow the access of authorized personnel as well as the control, monitoring and registration of said accesses and exits, as well as time of action, thus controlling those responsible for each repair or incident.

In this way, it is possible to minimize the execution times in the maintenance and repair of wind towers, as well as a perfect control of the operators who access them.

DESCRIPTION OF THE DRAWINGS

To complement the description that is going to be made below and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization thereof, a drawing is attached as an integral part of said description. For illustrative and non-limiting purposes, the following has been represented:

Figure 1.- Shows a schematic representation of a wind tower access control system made in accordance with the object of the present invention.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the outlined figure, it can be seen how the control system of the invention is intended to be implemented in each and every one of the different access doors (1) to the different compartments or modules of a plurality of wind towers ( 2), so that an electronic lock (3) will be established on said doors, with its corresponding electrical power supply (4), a lock associated with a control circuit (5) connected to a conventional communications module (6), or via satellite (7), (or the connection measures that each manufacturer or promoter has), through which to communicate and be controlled by a control center (8).

The control center (8) manages in real time the accesses to the different wind towers, as well as to their different internal rooms, so that the operators who intend to access them must first identify themselves for their registration and validation, since Not all operators can-must access all rooms of the wind turbine, a maneuver that can be done through an RFID identification card, for which the control circuit (5) will be associated with an RFID reader (9), or be identified through a control interface (10), to said control interface (10) being able to materialize in a simple telephone for access control.

Another easier identification and access option is that said process can be managed through a computer application by means of the operator's own mobile phone (11).

In any of the cases, to access the wind tower, the user must first identify himself and obtain permission from the central itself (control room, technical assistance service department, etc.), which will be in charge of granting the privileges of access according to each case, either to the interior of the ground floor, to the control panel, to the elevator, etc ... recording said accesses and length of stay.

Claims (7)

1a.- Access control system to wind towers, in which at least one access door and occasionally other interior doors are always established to the different compartments or modules of said wind tower, and to the elevator if it had one, characterized in that the door Access to the tower includes an electronic lock (3), with its corresponding electrical power supply (4), and which is associated with a control circuit (5) connected to a communications module (6), registration and remote control of access from a control center (8), said control circuit (5) including means of identification and validation / rejection of access for the operators. 2nd.- Access control system to wind towers, according to claim 1, characterized in that the interior doors and the access to the elevator have a closing commanded from the central control system. 3a.- Access control system to wind towers, according to claim 1, characterized in that the means of identification and validation / rejection of access for the operators are materialized in an RFID reader (9) of RFID identification cards. 4.- Access control system to wind towers, according to claim 1, Operator characters are embodied in a control interface (10), such as a telephone or a keyboard for entering a pre-assigned access number. 5.- Access control system to wind towers, according to claim 1, characterized in that the means of identification and validation / rejection of access for the operators are materialized in a computer application for communication with the control center (8) associated with the mobile phone (11) of the operator. 6.- Access control system to wind towers, according to claim 1, characterized in that the control circuit (5) is connected to a satellite communications module (7). 7a.- Access control system to wind towers, according to previous claims, characterized in that when activating any input order, the tower's wind generator stops for safety.
