[0019] The technical solution of the present application is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical solution of the present application, rather than limitations on the technical solution of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments can be combined with each other.

[0020] Figure 1 FIG. 1 is a schematic diagram of the overall process of an electromagnetic radiation environment assessment method based on data analysis according to an embodiment of the present application. Figure 1 As shown, the specific steps include: S110: Acquire the existing base station data, candidate base station data and regional personnel spatiotemporal distribution data in the environmental assessment area.

[0021] S120: Analyzing the signal strength distribution of terminal devices in the environment assessment area through the existing base station data, and determining the location of the terminal device with low signal strength; By analyzing the signal distribution of terminal devices that interact with existing base stations, it is possible to determine weak areas of signal coverage, such as signal blind spots and weak coverage areas. Weak areas of signal coverage may be caused by large base station spacing, building obstruction, complex terrain or interference factors. At the same time, when the terminal device is in a low signal strength environment, the device will automatically increase its own transmission power to maintain communication, thereby increasing the local electromagnetic radiation level. Therefore, determining the weak areas of signal coverage helps to reasonably plan the location of candidate base stations, so that the newly added base stations can maximize the signal coverage effect, thereby reducing the transmission power of the terminal equipment and reducing the overall electromagnetic radiation exposure. Determine the location of the terminal device with low signal strength, including: Obtain the existing base station data in the environmental assessment area, the existing base station data includes the location data of the existing base station, the configuration data of the existing base station, and the interaction data between the existing base station and the terminal device; The signal strength of the terminal device is extracted through the interaction data between the existing base station and the terminal device, where the signal strength refers to the signal power level received by the terminal device from the base station, such as RSRP (Reference Signal Received Power), RSSI (Received Signal Strength Indicator) and SINR (Signal-to-Interference-plus-Noise Ratio). The specific steps include: (1) the terminal device periodically reports RSRP, RSSI or SINR data to the base station; (2) the base station obtains the signal strength of the terminal device through the uplink (UL); The terminal device whose signal strength is less than the preset signal strength threshold is positioned by cellular network positioning technology to obtain the position of the terminal device with low signal strength, wherein the cellular network positioning technology is any one of E-CID, A-GNSS, DL-TDOA and UL-TDOA. In one embodiment of the present application, the preset signal strength threshold of the LTE (4G) terminal device is -105 dBm, and the preset signal strength threshold of the NR (5G) terminal device is -110dBm.

[0022] S130: Determine the locations of candidate base stations according to the location distribution of the terminal devices with low signal strength and the candidate base station data, and obtain a set of candidate base station locations; Based on the spatial distribution characteristics of low signal strength terminal devices and the signal coverage capabilities of candidate base stations, the locations of new base stations are selected to maximize the signal coverage of terminal devices and reduce signal blind spots. A set of candidate base station locations is obtained, including: The location distribution of low-signal-strength terminal devices is analyzed by spatial clustering algorithm to obtain the low-signal-strength terminal device clustering area; The candidate base station signal coverage area is determined by combining the candidate base station data with the path loss model, wherein the path loss model is any one of a free space path loss model, a ray tracing model and a Hata model.

Taking the free space path loss model as an example, the free space path loss model is: ; In the formula Indicates the carrier frequency, Indicates the distance between the base station and the terminal device. represents the base station path loss in the free space path loss model; Calculate the degree of overlap between the candidate base station signal coverage area and the low signal strength terminal device gathering area at different locations in the environmental assessment area; Positions where the area overlap is greater than or equal to a preset area overlap threshold are taken as candidate base station deployment positions and a set of candidate base station deployment positions is obtained.

[0023] S140: Analyze the electromagnetic radiation superposition of the candidate base station and the existing base stations at each candidate base station location in the candidate base station location set according to the existing base station data and the candidate base station data to obtain an electromagnetic radiation superposition area; By analyzing the electric field strength distribution of existing base stations and candidate base stations at different candidate locations, and determining the overlapping areas of base station electromagnetic radiation coverage, the impact of new base stations on the overall electromagnetic environment can be evaluated. At the same time, determining the electromagnetic radiation superposition area will be conducive to optimizing the location of candidate base stations, that is, by adjusting the location of candidate base stations without affecting signal coverage, unnecessary electromagnetic radiation accumulation can be reduced, and the electromagnetic radiation superposition area can be obtained, including: The electromagnetic propagation model of the communication base station is constructed and the electric field strength distribution data of the existing base station and the candidate base station are calculated by combining the existing base station data and the candidate base station data. Since the electromagnetic radiation in the mobile communication frequency band is non-ionizing radiation, and the greater the radiation intensity of the field source, the higher the degree of electromagnetic pollution, the higher the frequency, and the longer the contact time, the higher the degree of harm to the human body. Therefore, when evaluating the electric field strength distribution of the base station, the propagation environment of the outdoor base station signal is considered. Since the use scenarios of the spatial loss model under ideal conditions are relatively limited, it is inevitable that there are mirror reflections or diffuse reflections that are difficult to block in the actual environment. Therefore, more complex path loss models need to be considered. Therefore, the electromagnetic propagation model of the communication base station is any one of the Okumura-Hata model, COST 231-Hata model, and COST 231-Walfish-Ikegami model.

In one embodiment of the present application, the number of personnel and the average length of stay of personnel are normalized using the Min-Max normalization method. The calculation formula of the Min-Max normalization method is: ; In the formula represents any variable among the number of personnel and the average length of stay of personnel, and They represent the maximum and minimum values ​​of the variable in the electromagnetic radiation coverage area and electromagnetic radiation superposition area of ​​all candidate base stations, respectively. represents the normalized variable; The product of the number of personnel in the electromagnetic radiation coverage area of ​​the candidate base station and the average length of stay of the personnel after normalization is taken as the electromagnetic radiation influence coefficient of the electromagnetic radiation coverage area of ​​the candidate base station; The product of the normalized number of people in the electromagnetic radiation superposition area and the average length of stay of the people is taken as the electromagnetic radiation influence coefficient of the electromagnetic radiation superposition area.
