[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figure 1-3The utility model provides a technical solution: an intelligent sensing window opening device based on optical fiber sensor, comprising a casement drive component 1 detachably installed inside the window frame, a driving structure and a transmission structure installed inside the casement drive component 1, the casement drive component 1 is electrically connected to a controller 2, and the controller 2 is also electrically connected to a lock box 3 and an optical fiber sensor 4, respectively. The transmission structure of the casement drive component 1 passes through the outer wall of the casement drive component 1 and is installed with one end of a casement slide arm 5, and the other end of the casement slide arm 5 is installed at the upper end of the window sash, the driving structure passes through the outer wall of the casement drive component 1 and is connected with a wiring terminal 6, the optical fiber sensor 4 is installed around the window frame and close to the edge of the window frame, the optical fiber sensor 4 is used to detect temperature changes, automatically adjust the opening and closing angle of the window sash to optimize the indoor light distribution, and ensure accurate perception of the surrounding light and the approach of objects.

[0016] The optical fiber sensor 4 has 12 optical fiber temperature measuring points 7 evenly arranged around the window frame, which are connected to the stacked demodulator device through optical fiber jumpers and optical connectors. The temperature signals collected by the device are uploaded to the cloud through the UDP protocol. The signals collected by the temperature measuring points of the optical fiber sensor are analyzed and processed into corresponding temperatures through the cloud. When abnormal temperature signals appear, the air leakage of the window can also be checked according to the temperature measuring points. If the window is not airtight, the change of the external temperature will affect the temperature distribution around the window more quickly. The optical fiber temperature measurement system can capture this change, thereby indirectly evaluating the airtightness of the window; the temperature signals of the temperature measuring points of the optical fiber sensor can also be collected to calculate the heat transfer coefficient of the frame with reference to the "Thermal Calculation Code for Building Doors, Windows and Glass Curtain Walls" JGJ / T 151-2008, and the heat transfer coefficient of the window can also be further inferred.

[0017] A slideway and a slider are provided at the upper end of the window sash, and the slider is rotatably connected to the casement slide arm 5.

[0018] The connection terminal 6 is used to connect an external power source and a data transmission line to ensure stable power supply and real-time control of the swing drive assembly 1.

[0019] The drive structure and the motor in the lock box are connected to the network via the Modbus485 protocol, thereby realizing remote reception of control commands and remote start or stop.

[0020] The casement drive assembly 1, the lock box 3 and the optical fiber sensor 4 can be installed by selecting suitable assemblies according to the specific size and shape of the window frame. At the same time, the components are connected by standardized interfaces, and can be assembled without professional tools, which can greatly reduce the difficulty and cost of installation.

[0021] The controller 2 has a built-in intelligent algorithm module, which can automatically analyze and determine whether to open or close the window based on the multi-dimensional data such as ambient temperature, humidity, light intensity, etc. collected by the optical fiber sensor 4, so as to achieve the purpose of energy saving, ventilation or rain protection, etc. At the same time, the user can also personalize the controller 2 through a mobile phone APP or a remote device such as a remote controller to meet the needs of different life scenarios.

[0022] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows:

[0023] First, when the device is started, the optical fiber sensor 4 immediately enters the working state, and its built-in multiple optical fiber temperature measurement points 7 will start to continuously collect ambient temperature data around the window frame. At the same time, the optical fiber sensor also has the ability to perceive humidity and light intensity, and through comprehensive analysis of these multi-dimensional environmental parameters, it provides comprehensive and accurate data support for subsequent intelligent decision-making.

[0024] Next, the controller 2 will periodically receive data from the optical fiber sensor 4 and start the built-in intelligent algorithm module for processing. This module can automatically open the window to promote ventilation and cooling according to the preset algorithm logic, such as when the indoor temperature is higher than the set threshold, or predict rainfall according to light intensity and humidity changes on rainy days, and close the window in advance to prevent rainwater from intruding. These decision-making processes are based on real-time environmental data, ensuring the intelligence and accuracy of the window opening device, and, specifically at the algorithm logic level, are not within the scope of protection of this application.

[0025] When automatically opening or closing the window, the controller 2 sends instructions to the casement drive assembly 1 and the lock box. When the lock box receives the instruction signal, it drives the internal motor to control the unlocking. After the casement drive assembly receives the instruction, the internal drive structure will start and drive the casement slide arm 5 to slide through the transmission structure. The other end of the casement slide arm is connected to the slider at the upper end of the window sash, so as the slide arm moves, the window sash will also open or close. The whole action process is smooth, reliable, and low-noise, and will not interfere with the indoor environment.

[0026] In addition, in order to ensure the stable operation and real-time control of the equipment, the terminal 6 is responsible for connecting the external power supply and the data transmission line. It not only provides stable power support for the swing drive assembly 1, but also undertakes the important task of data transmission, so that the controller 2 can receive the data of the optical fiber sensor 4 in real time and quickly convey the control instructions to the drive assembly.

[0027] In summary, the intelligent sensing window opening device based on optical fiber sensors of the utility model realizes intelligent sensing and automatic control of windows by integrating advanced sensing technology, intelligent algorithms and automatic control technology. It can not only automatically adjust the opening and closing state of windows according to environmental changes, but also provides the function of user-defined settings, bringing users a more convenient, comfortable and energy-saving life experience.
