Description

Technical Field

[0001] The present invention relates to the technical field of wind turbines, and specifically to a safety access control management system and management method for wind turbines. Background Art

[0002] Wind turbines mainly rely on wind to drive the blades to rotate. When the wind blows towards the blades of the wind turbine, the blades will rotate under the action of aerodynamic force. The rotation of the blades drives the generator rotor connected thereto to rotate. According to the principle of electromagnetic induction, when a conductor moves in a magnetic field to cut the magnetic induction line, an induced electromotive force will be generated, thereby generating electric energy in the stator winding of the generator. The generators in wind turbines mainly have two types: asynchronous generators and synchronous generators. Asynchronous generators have a simple structure and low cost, and are widely used in wind power generation. Synchronous generators have higher efficiency and better power quality control capabilities. The access control system of wind turbines is an important facility to ensure the safe operation of wind turbines and prevent unauthorized personnel from entering;

5. A security access control management system and management method for wind turbines according to claim 4, characterized in that: A buffer pad (717) is installed at the front end of the rotating seat (715).

6. A security access control management method for a wind turbine, which is applied to a security access control management system for a wind turbine as claimed in claim 5, characterized in that: The following steps are involved: Step 1: The staff uses the card issuer to connect to the backend server. The manager enters the relevant information of the staff who need to open the access control authority on the management platform, such as name, department, scope of work authority and accessible wind turbine area. After the information is written into the IC card through the card issuer, the IC card and the corresponding passive key are distributed to the staff together with the authority setting; Step 2: When the staff holding the IC card arrives at the door body component, he / she places the IC card close to the sensing area of ​​the card reader. The card reader reads the identification information of the IC card and sends the information to the management platform through the background server; Step 3: The management platform verifies according to the pre-set permission rules. If the person's permission meets the current door entry requirements within the allowed time period, the management platform sends an unlocking command to the lock body in the lock mechanism through the background server. After the lock body receives the unlocking command from the background server, it controls the lock mechanism to unlock, and the door of the door mechanism can be opened. At the same time, the door opening sensor detects the opening action of the door body and sends the door opening signal to the management platform through the background server. The management platform records the door opening time and personnel information related data. If the IC card read by the card reader does not match the permission, the background server will record the information of the illegal card swiping attempt, including the time and card number for subsequent investigation; Step 4: When a person outside the door wants to enter but does not have the appropriate permission to open the door, he or she can initiate a call request by using the intercom on the door body. The intercom sends the call signal to the background server, which transfers the call to the phone. The manager on the phone side talks with the person outside the door, and after understanding the purpose of the visit, he or she can remotely control the lock body to open; Step 5: When the door body (3) is opened, the first electric telescopic rod (68) extends to drive the bottom connecting shaft (65) to move downward, and the bottom connecting shaft (65) drives the top connecting shaft (65) to move synchronously with the cooperation of the left and right connecting plates (66). The upper and lower connecting shafts (65) respectively drive one end of the upper and lower V-shaped rotating seats (64) to move downward, and drive the rotating shafts (63) on both sides to rotate with the cooperation of the two groups of V-shaped rotating seats (64), so that the V-shaped rotating seats (64) The rotating shaft (63) is rotated with the axis as the axis, and the upper and lower V-shaped rotating seats (64) drive the connecting seats (69) at the corresponding positions to move backward, so that under the push of the upper and lower connecting seats (69), the mounting plate (610) moves from the inner cavity of the storage shell (61) to the outside, and the rotating module (611) drives the mounting seat (71) to rotate. The mounting seat (71) cooperates with the fixing plate (72) to rotate the rotating frame (78) in the counterclockwise direction from the vertical state to the horizontal state; Step 6: The second electric telescopic rod (75) drives the U-shaped frame (76) to drive the insertion rod (77) to move to the left. While the insertion rod (77) moves in the slot (74) and the inner cavity of the limit slot (79), the limit slot (79) cooperates with the rotation frame (78) to rotate forward on the inner side of the slot body seat (73). The third electric telescopic rod (712) extends to drive the first rotation frame (711) to rotate forward on the inner side of the fixed seat (710). The fourth electric telescopic rod (714) extends to drive The second rotating frame (713) is driven to rotate forward or backward on the inner side of the first rotating frame (711), and the fifth electric telescopic rod (716) is extended and shortened to drive the rotating seat (715) to rotate forward or backward on the outer side of the second rotating frame (713), thereby making the buffer pad (717) fit with the inner side of the door body (3) under the cooperation of the first rotating frame (711), the second rotating frame (713) and the rotating seat (715), so as to play an auxiliary supporting role after the door body (3) is opened; Step 7: If someone attempts to illegally dismantle the lock mechanism, the anti-dismantling alarm installed on or near the lock body will be triggered, and the anti-dismantling alarm will send an alarm signal to the background server. At the same time, the lock body itself enters a locked state. After receiving the alarm signal, the background server will issue an alarm notification, display the alarm information on the management platform, and send SMS or email notifications to relevant personnel.
