[0020] Example 1 like Figure 1 As shown, a multi-dimensional electrical safety prediction and fire early warning system includes an early warning cloud server 1 and an edge data processing device 2, the edge data processing device 2 being connected to the early warning cloud server 1. It also includes a multi-dimensional monitoring device 3 and a fire-fighting device 4, both of which are electrically connected to the edge data processing device 2.

[0021] The multi-dimensional monitoring device 3 includes a temperature sensor 31, a smoke sensor 32, an infrared thermal imager 33, an image acquisition unit 34, a gas sensor 35, and a flame sensor 36. The infrared thermal imager 33, the image acquisition unit 34, the gas sensor 35, and the flame sensor 36 are mounted on the scanning mechanism 5, which is connected to the cooling fan 7.

[0022] Temperature sensor 31 includes contact temperature sensor 31 and infrared temperature sensor 31. The contact temperature sensor 31 and infrared temperature sensor 31 are installed according to the internal layout of the electrical equipment. Smoke sensor 32 is set on the top of the electrical equipment or linearly distributed on the inner wall of the electrical equipment. The contact temperature sensor 31, infrared temperature sensor 31 and smoke sensor 32 are all electrically connected to edge data processing device 2 for collecting temperature data and smoke data.

[0023] To improve the comprehensiveness of the collected data, a scanning mechanism 5 is provided, which moves the data collection mechanism. For example... Figure 2 - Figure 3 As shown, in this embodiment, the scanning mechanism 5 includes a mounting plate 51. The mounting plate 51 is connected to two mirror-aligned scanning drive racks 52. The two scanning drive racks 52 mesh with the outer sides of two sector-shaped drive plates 53, which are respectively mounted on two drive shafts 54. The two drive shafts 54 are connected to a drive shaft 55 via a bevel gear set. The drive shaft 55 is connected to the output shaft of a cooling fan 7 via a bevel gear set. The cooling fan 7 is electrically connected to the edge data processing device 2. An infrared thermal imager 33, an image acquisition unit 34, a gas sensor 35, and a flame sensor 36 are mounted on the mounting plate 51. All of these components are electrically connected to the edge data processing device 2. This allows for scanning and acquisition of data inside electrical components while simultaneously dissipating heat.

[0024] The fire-fighting device 4 includes a perfluorohexanone fire extinguisher 41 installed outside the electrical equipment.

[0025] The fire early warning method based on the above-mentioned multi-dimensional electrical safety prediction and fire early warning system comprises the following specific steps: Step S1: Arrange the temperature sensor 31 and the smoke sensor 32 according to the distribution of electronic components inside the electrical equipment.

[0026] Step S2: The edge data processing device 2 collects the detection data from the multi-dimensional monitoring device 3 in real time, processes the collected detection data, and then obtains the early warning result through the internal analysis module.

[0027] Step S3: Based on the warning result, the scanning mechanism 5 and the fire-fighting mechanism are triggered. At the same time, the edge data processing device 2 sends the warning result to the warning cloud server 1, and sends the warning information to the corresponding management terminal through the warning cloud server 1 for warning.

[0028] When the temperature of temperature sensor 31 exceeds the first set temperature value, the cooling fan is activated, simultaneously driving the scanning mechanism 5 to reciprocate and perform infrared thermal imaging, video recording, corresponding gas concentration detection, and detection of the presence of flames. When the temperature of temperature sensor 31 remains above the second set temperature value, or when an abnormal fire point is detected based on data analysis from the infrared thermal imager 33, image acquisition unit 34, gas sensor 35, and flame sensor 36 on the scanning mechanism 5, the cooling fan 7 is shut off and the output valve 42 is opened to extinguish the fire. The amount of extinguishing agent used is calculated based on the area of ​​the abnormal point, the corresponding gas concentration, and the size of the flames to avoid wasting fire-fighting resources. The calculation formula is as follows: ; Where m is the amount of extinguishing agent used, which is a proportionality coefficient related to the area of ​​the abnormal point, the corresponding gas concentration, and the size of the flame; a is a fixed coefficient; V is the volume of the electrical equipment; and S is the specific volume of the superheated vapor of the extinguishing agent at 101 kPa atmospheric pressure and the lowest ambient temperature of the electrical equipment.

[0029] Example 2 The difference between this embodiment and Embodiment 1 is that the scanning mechanism 5 is different, such as... Figure 5 As shown, Embodiment 1 involves vertical scanning movement. In this embodiment, the mounting plate 51 of the scanning mechanism 5 moves horizontally back and forth. The scanning mechanism 5 includes a mounting plate 51.
