and the processor 4 is configured to calculate a corrected position coordinate of the terminal positioning device 2 by using a carrier phase differential algorithm according to the first satellite positioning data, the second satellite positioning data and the real coordinate value of the reference positioning station 1.
Specifically, the reference point may be set autonomously, for example, may be set on a roof of a certain high-rise building, etc. so as to better acquire the first satellite positioning data, and the embodiment of the present invention is not limited herein.
Specifically, the terminal positioning device 2 may be carried by a worker, and may obtain second satellite positioning data of the terminal positioning device (i.e., the worker), in real time, where the second satellite positioning data is data with poor precision mentioned in the above background art, and the second satellite positioning data is likely to have a large error.
In this way, the staff in the plurality of substations can be accurately positioned (the corrected position coordinates of the staff in the plurality of substations are obtained) at the same time.
Specifically, the processor 4 may be of various types, such as a single chip microcomputer, and the embodiment of the present invention is not limited herein.
The carrier phase differential algorithm is an algorithm with high accuracy for correcting satellite positioning data, and can generally control the error of the satellite positioning data to be in the centimeter level, and certainly, the carrier phase differential algorithm needs to calculate the multi-band real-time satellite positioning data of a reference point (namely, the first satellite positioning data in the embodiment of the invention), the real coordinate value of the reference point and the multi-band satellite positioning data of a coordinate point to be corrected (namely, the second satellite positioning data of a worker in a transformer substation in the embodiment of the invention), wherein the multi-band can be specifically a plurality of numerical values, for example, the multi-band can be three frequency bands, and the more frequency bands are beneficial to reducing the finally obtained error of the corrected position coordinate.

as a preferred embodiment, the system for locating the staff in the substation further comprises:
a first reflected signal suppression device 5 disposed at the reference positioning station 1, for suppressing the satellite signal reflected and propagated to the reference positioning station 1;
and a second reflected signal suppression device 6 disposed in the terminal positioning apparatus 2, for suppressing the satellite signal reflected and propagated to the terminal positioning apparatus 2.
Specifically, the reference positioning station 1 and the terminal positioning device 2 receive satellite signals from the direction of a satellite on the sky, but the satellite signals are propagated from multiple paths, the satellite signals are likely to be reflected on objects around the reference positioning station 1 and the terminal positioning device 2 and then received by the reference positioning station 1 and the terminal positioning device 2, the satellite signals propagated to the reference positioning station 1 and the terminal positioning device 2 after being reflected are inaccurate, the satellite signals propagated to the reference positioning station 1 and the terminal positioning device 2 after being reflected should be eliminated, and only the satellite signals directly propagated to the reference positioning station 1 and the terminal positioning device 2 without being reflected are retained, so that the accuracy of the first satellite positioning data and the second satellite positioning data can be improved, and the accuracy of the final corrected position coordinates can be improved, the safety of staff in the transformer substation is further improved.
Specifically, the first reflected signal suppression device 5 and the second reflected signal suppression device 6 may be disposed on the receiving antennas of the reference positioning station 1 and the terminal positioning device 2, respectively, and may have a good suppression effect.
As a preferred embodiment, the processor 4 is further configured to:

Specifically, considering that a hardware device such as a reflected signal suppression device can only suppress the reflected satellite signal to a certain extent, but cannot completely eliminate the reflected satellite signal, the embodiment of the present invention may further adopt a preset algorithm to eliminate the reflected satellite signal in the acquired first satellite positioning data and the acquired second satellite positioning data, so as to further improve the accuracy of the finally obtained corrected position coordinate.
As a preferred embodiment, the predetermined algorithm is EMD (Empirical Mode Decomposition).

and adopting a preset rule to select one of the candidate position coordinates as a correction position coordinate.
Specifically, considering that a single satellite system may not be able to obtain accurate corrected position coordinates of the staff under certain conditions due to changes of the staff, for example, when an off-spectrum corrected position coordinate occurs, in the embodiment of the present invention, corrected coordinate values (which may also be referred to as alternative position coordinates) corresponding to multiple satellite systems may be calculated according to the first satellite positioning data, the second satellite positioning data of multiple frequency bands corresponding to each satellite system and the real coordinate value of the reference positioning station 1, and then a more accurate one is selected from the corrected position coordinates as a final corrected position coordinate through a preset rule, so that corrected position coordinates with higher accuracy may be reliably obtained.
The preset rule may be multiple, for example, a certain satellite positioning system may be first used as a default positioning system, if the corrected position coordinate of the satellite positioning system does not have a large deviation, the corrected position coordinate calculated by the satellite positioning system may be used as a final corrected position coordinate, and if the corrected position coordinate of the satellite positioning system is greater than a preset threshold, an alternative position coordinate calculated by another satellite positioning system may be used as the corrected position coordinate, which is not limited herein.
