They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In the description of the present invention, it should also be noted that, unless otherwise clearly specified and limited, the terms "setting", "installation", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0022] like Figure 1 As shown, a sensor-based multi-scenario fire safety monitoring system includes a central control management terminal 1 and a plurality of tower base data boxes 2 connected to the central control management terminal 1 via communication optical fiber, the plurality of tower base data boxes 2 are connected to the corresponding tower top data boxes 3, and the tower top data boxes 3 are connected to the sensor device 4 and the multi-scenario fire protection device 5 located in the cabin.

[0023] like Figure 2 - Figure 3 As shown, the sensor device 4 arranges multiple sensors at key parts of the wind turbine, and the system can monitor multiple parameters such as environmental temperature and humidity, smoke concentration, flame radiation, etc. in real time, so as to predict flames and temperature abnormalities in advance and discover potential fire risks in time. The sensor device 4 includes an in-cabin environment sensor component 41, an in-cabin environment sensor component 42, an out-cabin environment sensor component 43, a fan running component sensor component 44, an image acquisition component 45, and a position data acquisition component 46.

[0024] The cabinet environment sensor assembly 41 is arranged in the control cabinet 6 inside the cabin and includes a temperature sensor, a breath sensor, a smoke sensor and a partial discharge sensor; the temperature sensor, the breath sensor, the smoke sensor and the partial discharge sensor are all electrically connected to the tower top data box 3, and are used to collect the temperature, smoke, gas concentration and partial discharge data in the control cabinet 6 in real time. The breath sensor monitors the concentration of trace carbon monoxide, carbon dioxide, hydrogen sulfide and sulfur dioxide in the environment, providing an important basis for the fire warning of the wind turbine generator set, and can simultaneously detect the concentration of carbon monoxide (CO), carbon dioxide (CO2), hydrogen sulfide (H2S) and sulfur dioxide (SO2) in the environment. These gases are common products when a fire occurs, so the composite breath sensor plays a vital role in fire warning. When the concentration of these gases in the environment exceeds the preset safety threshold, the sensor will immediately sound an alarm to notify the operation and maintenance personnel to take timely measures to prevent the occurrence or spread of the fire. The composite breath sensor can also provide real-time data to help the operation and maintenance personnel understand the gas environment inside the wind turbine generator set, providing an important reference for the operation and maintenance of the equipment.

[0025] The cabin environment sensing component 42 includes a temperature and humidity sensor, a smoke sensor, a breath sensor, a dual-beam flame detector and a smoke diffusion analyzer. The temperature and humidity sensor, the smoke sensor, the breath sensor, the dual-beam flame detector and the smoke diffusion analyzer are all electrically connected to the tower top data box 3, and the smoke sensor is electrically connected to the smoke diffusion analyzer. Real-time monitoring of the temperature and humidity changes in the surrounding environment. Temperature and humidity data are important indicators for evaluating the operating status and safety of wind turbines. Excessive temperature may mean equipment overload or poor heat dissipation, and abnormal humidity changes may indicate potential electrical failures or corrosion risks. By real-time monitoring of these data, operation and maintenance personnel can promptly discover potential safety hazards. The point-shaped dual-beam flame detector is an efficient and sensitive fire warning device. The dual-beam flame detector uses the dual-beam principle to accurately monitor the changes in flames in the environment by emitting and receiving two beams of light. Once the detector senses the presence of a flame, it will immediately trigger the alarm system to notify the operation and maintenance personnel to take timely countermeasures. The smoke diffusion analyzer can quickly capture the presence of smoke and analyze its concentration and diffusion rate through precise sensors.

[0026] The extravehicular environment sensing assembly 43 includes a temperature sensor, an altitude pressure detector, a wind speed sensor, and a wind direction sensor, which are all electrically connected to the tower top data box 3. The altitude pressure detector measures the altitude and atmospheric pressure of the generator location in real time.

The radiation heat flux detector is used to monitor the thermal radiation flux around the generator in real time, and can accurately measure the thermal radiation energy generated during the operation of the generator. By real-time monitoring of the changes in the thermal radiation flux, the radiation heat flux detector can promptly detect abnormal conditions such as overheating of the generator and poor heat dissipation.

[0028] The image acquisition component 45 includes an infrared monitor that collects internal image data and infrared image data in real time, which can monitor the temperature distribution of various parts of the generator in real time, accurately detect abnormal hot spots, and effectively prevent the risk of fire caused by overheating of the equipment.

[0029] The position data acquisition component 46 includes a locator (using a dual-link wind turbine locator, model CLN02020V10), which is used to collect the current position of the wind turbine. It integrates the two major global positioning systems, Beidou and GPS, and realizes signal complementarity and enhancement through dual-link technology. It can provide stable and accurate positioning information even in complex environments. The dual-link wind turbine locator helps to optimize the operating posture and position adjustment of the wind turbine, thereby improving power generation efficiency and reducing operation and maintenance costs.
