FIG. 2 is a flowchart of an intelligent door lock control method for a tower of a wind turbine generator system provided by the invention.
Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.
The invention relates to an intelligent door lock control system and method for a tower of a wind turbine generator system and the wind turbine generator system, which solve the problems that irrelevant personnel mistakenly enter the tower and forcibly break into the tower through a corresponding control strategy and also solve the problem that a traditional mechanical lock is forgotten to carry a tower door key or lose the key. The central control system can be managed uniformly, and the loss of unit equipment and personnel can be avoided or reduced when the unit is stolen.
Fig. 1 shows the structure of an intelligent door lock control system of a tower of a wind turbine. Referring to fig. 1, the hardware part of the intelligent door lock control system of the tower barrel of the wind turbine generator at least comprises nine parts, namely a sensor, a power supply unit, a communication unit, a storage unit, a control unit, a camera shooting unit, a voice prompt unit, an identity recognition unit and a door lock body. The functions of each part are as follows:
the sensor comprises a proximity sensor arranged inside the door lock and a travel switch arranged on the tower door. The proximity sensor is used for detecting whether an operator approaches the tower door or not, and when the operator approaches the tower door, the proximity sensor feeds back to the control unit to be analyzed by the control unit.

The control unit is used as the core of the intelligent door lock system, obtains signal input from the sensor and other units, performs data processing according to self control logic and algorithm, and sends out control commands to control the opening and closing of the door lock, the operation of the identity recognition unit and the camera unit, the starting and stopping of the voice prompt unit and the like.
The start of the camera shooting unit and the voice prompt unit is controlled by the control unit and is used for recording the whole process from door entering to door exiting of an operator and transmitting image data to the storage unit. The voice prompt unit can be provided with various voices for prompting operators and scaring away lawbreakers.
The identity recognition unit is used for confirming the identity of the operator. If the operator who enters the tower drum is not authorized in advance, and the identity identification unit cannot confirm the identity information, the tower drum door is refused to be opened. If the identity recognition unit confirms the information of the operator who enters the tower drum, the control unit sends a control command to the door lock body, the tower drum door lock is opened, and the operator agrees to enter the tower drum.
FIG. 2 shows a flow of an intelligent door lock control method for a tower of a wind turbine. Referring to fig. 2, an operation flow of the intelligent door lock control method for the tower of the wind turbine generator is described below.
The proximity switch is integrated inside the intelligent door lock or installed near the door lock and used for detecting whether an operator approaches the tower door. Once having operating personnel to approach the tower door, can send feedback signal to the controller, the voice prompt unit is controlled to the control unit after data processing, and the door lock can send voice prompt operating personnel to verify the identity promptly.
The operator sends identity information to the controller through the identity recognition unit, the controller compares the received identity information with the identity information in the database, if the identity of the operator is authorized, the door lock is controlled to be opened, the camera in front of the tower drum door is started simultaneously, the operator is photographed, the personnel information and the entering time are recorded, and the personnel information and the entering time are stored in the storage unit and are managed and consulted by the central control system. If the identity of the operator is not authorized, the controller controls the voice prompt unit to prompt the operator to perform identity authentication again. If the identity is unauthorized, but a travel switch action or a door lock of the tower drum door is damaged, it is shown that a lawless person forcibly breaks into the tower drum, and the operation safety of the unit can be influenced, at the moment, the controller can start a camera in the tower drum to record the whole process that an operator enters the tower drum and leaves the tower drum, and control the voice prompt unit to send an audible and visual alarm signal, and can operate the main breaker to cut off the power supply, so that the personal safety of the operator is ensured.
The identity recognition unit comprises various modes such as face recognition, fingerprint recognition, authorization code recognition and the like.
The camera unit comprises a camera facing the outside of the tower drum door and a plurality of cameras installed inside the tower drum, and the opening and closing of the cameras are controlled by a controller.
The communication unit is compatible with various communication interfaces such as optical fibers, RS232, RS485, RS422, Ethernet, Bluetooth and the like. Can communicate with the main control system and the central control system of the unit through the exchanger.
The voice prompt unit can send out various prompt tones according to the control strategy of the controller. The content of the prompt tone can be changed according to actual needs.
The power supply unit is internally provided with a power supply protection function, so that multiple protection functions including overcurrent protection, overvoltage protection, undervoltage protection, overtemperature protection, ground fault protection, three-phase unbalance protection and the like can be realized, and the power utilization safety of the system is guaranteed.
The lock belt mechanical key socket, in case when the unit cuts off the power supply for a long time, the unable work of intelligence lock system, the tower section of thick bamboo door is opened to accessible mechanical key.
The invention has the advantages that:
the invention can be used as an independent control scheme, can detect whether an operator approaches the tower barrel door or not and can detect the opening/closing state of the tower barrel door, verifies the identity of the operator entering the tower through the identity verification unit, forbids unauthorized irrelevant personnel to enter, can realize the anti-theft function of the unit, and ensures the operation safety of the unit.
The door lock used by the invention is an intelligent door lock, and operators can enter the tower barrel without using a mechanical key after completing identity verification, thereby avoiding troubles caused by losing or forgetting to carry the key.
When a lawbreaker illegally breaks into the tower theft equipment and the cable, the camera is automatically started to pick up the image of the tower theft equipment and the cable, and the alarm is given immediately, so that related personnel can be reminded to arrive at the site at the first time, the unit loss is reduced to the minimum, and strong evidence is provided for the public security organization to catch the lawbreaker according to law. Meanwhile, the main power supply of the unit is disconnected, and the human casualties caused by the fact that lawless persons can not understand the working principle of the unit and operate equipment randomly are avoided.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention in any way, and it will be apparent to those skilled in the art that the above description of the present invention can be applied to various modifications, equivalent variations or modifications without departing from the spirit and scope of the present invention.
