Description

Technical Field

[0001] The present invention relates to a monitoring system and method, and in particular to a wind turbine monitoring system and method based on BIM. Background Art

[0002] BIM (Building Information Modeling) is another revolutionary computer application technology in the engineering and construction industry after CAD (Computer-Aided Design) technology. BIM can help realize the integration of building information. From the design, construction, operation to the end of the building's entire life cycle, all kinds of information are always integrated in a three-dimensional model information database. Design teams, construction units, facility operation departments, owners and other parties can work together based on BIM, effectively improving work efficiency, saving resources, reducing costs, and achieving sustainable development.

[0003] The core of BIM is to establish a virtual three-dimensional model of the construction project and use digital technology to provide this model with a complete and actual construction project information database. This information database not only contains geometric information, professional attributes and status information describing the building components, but also contains status information of non-component objects (such as space and motion behavior). With the help of this three-dimensional model containing construction project information, the degree of information integration of the construction project is greatly improved, thus providing a platform for engineering information exchange and sharing for the stakeholders of the construction project.

[0004] With the continuous development of information technology, BIM (Building Information Modeling) technology has been widely used in various fields. BIM technology is a digital tool used in engineering design, construction, and management. By integrating the digital and information models of buildings, sharing and transmitting them in the entire life cycle of project planning, operation, and maintenance, it enables engineering and technical personnel to correctly understand and efficiently respond to various building information, playing an important role in improving production efficiency, saving costs, and shortening construction periods.

[0005] At present, the monitoring device of the wind turbine generator set is set at the entrance to monitor the entry and exit of personnel, or the monitoring device of the wind turbine generator set is set at a fixed position in the cabin to monitor the operation of the equipment. The monitoring device of the wind turbine generator set can upload the monitored images to the monitoring system. However, the current existing monitoring method cannot fully utilize the monitoring device because the location of the monitoring device of the wind turbine generator set is fixed, and each monitoring device is responsible for an area. In addition, the existing monitoring device of the wind turbine generator set lacks analysis and alarm for abnormal situations, and cannot promptly remind the staff to deal with the monitored abnormal situations. Summary of the invention

[0006] In order to solve the deficiencies of the above technologies, the present invention provides a wind turbine monitoring system and method based on BIM.

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is: a BIM-based wind turbine monitoring system, including a monitoring device, a transmission device, a sensor, a BIM-based model database, and a service host. The monitoring device transmits the monitoring image to the service host, and the service host analyzes the monitoring image of the monitoring device in combination with the data in the BIM-based model database, judges the state of the wind turbine generator set, and sends an alarm signal.

[0008] Preferably, the transmission device is in the form of a guide rail or a transmission chain that runs through the nacelle and the tower of the wind turbine.

[0009] Preferably, the sensor is a displacement sensor for determining the position of a tower door of the wind turbine, and the transmission device is interlocked with the tower door of the wind turbine by using the sensor.

[0010] Preferably, the monitoring device is arranged on a transmission device, and the transmission device can transmit the monitoring device between the bottom tower of the wind turbine and the top nacelle of the wind turbine.

[0011] Preferably, the monitoring device is an infrared camera, which can take clear pictures at night, and rainy and foggy weather will not affect the image quality.

[0012] Preferably, the infrared camera is transmitted to the service host via optical fiber or wirelessly.

[0013] Preferably, the service host combines the monitoring image of the monitoring device with the data of the BIM-based model database for analysis to determine the status of the wind turbine generator set; when the person entering the wind turbine generator is an unregistered person or the monitored equipment operates abnormally, the service host sends an alarm signal.

[0014] Preferably, the monitoring device can manually or automatically perform full-scene monitoring of the interior of the wind turbine.

[0015] Preferably, the wind turbine monitoring system further comprises a manual control device, which is arranged at the tower door at the bottom of the wind turbine, and is used for manually controlling the transmission device on site to transfer the monitoring device to a designated position.

[0016] A working method of a wind turbine monitoring system based on BIM is:

[0017] When the wind turbine is automatically monitored through the monitoring device, when the tower door at the bottom of the wind turbine is opened, the sensor interlocked with the tower door determines the position of the tower door, and the transmission device transmits the monitoring device from the top nacelle of the wind turbine to the bottom tower of the wind turbine, and the situation of personnel entering and exiting the tower door is monitored through the monitoring device; when the tower door of the wind turbine is closed, the sensor interlocked with the tower door determines the position of the tower door, and the transmission device transmits the monitoring device from the bottom tower of the wind turbine to the top nacelle of the wind turbine, and the status of the equipment is monitored through the monitoring device;

[0018] When the wind turbine is monitored manually through the monitoring device, when the monitoring device is required to monitor the entry and exit of personnel at the tower door at the bottom of the wind turbine, the manual control device is manually operated to transmit the monitoring device from the top cabin of the wind turbine to the bottom tower of the wind turbine through the transmission device, so as to realize the monitoring of the tower door by the monitoring device; when the monitoring device is required to monitor the equipment located in the top cabin of the wind turbine, the manual control device is manually operated to transmit the monitoring device from the bottom tower of the wind turbine to the top cabin of the wind turbine through the transmission device, so as to realize the monitoring of the equipment in the top cabin;

[0019] The service host analyzes the monitoring images of the monitoring device in combination with the data in the BIM-based model database to determine the status of the wind turbine generator set. When the person entering the tower door of the wind turbine is an unregistered person or the monitored equipment in the cabin operates abnormally, the service host sends an alarm signal.

[0020] The service host of the BIM-based wind turbine monitoring system of the present invention can combine the monitoring image of the monitoring device with the data in the BIM-based model database for analysis, and judge the status of the wind turbine generator set. When the person entering the tower door of the wind turbine is an unregistered person or the monitored equipment in the cabin is operating abnormally, the service host sends an alarm signal; the monitoring system transmits the monitoring device between the top cabin of the wind turbine and the bottom tower of the wind turbine through a transmission device, and the position of the monitoring device is changed according to the actual situation. The limited number of monitoring devices can be fully utilized to monitor different positions of the wind turbine generator, which greatly improves the utilization rate of the monitoring device, and can realize that after the monitoring device detects an abnormal situation, the service host alarms to remind the staff to deal with the monitored abnormal situation.
