9. The BIM model-based 220kv indoor substation digital simulation test system according to claim 8, wherein: the output end of the model online analysis unit (420) is connected with a real-time guidance information output unit (430).
10. The BIM model-based 220kv indoor substation digital simulation test system according to claim 2, wherein: the surrounding environment measuring module (111) adopts a height prediction algorithm, and the algorithm formula is as follows:
H＝L sinβ；
Figure FDA0003648209380000021
Figure FDA0003648209380000022
wherein L is the distance from the camera to the highest point of the measuring point, beta is the included angle formed between the camera and the horizontal plane, H is the height of the measuring point, and V is the distance between the camera and the highest point of the measuring point 0 For the speed of light, T is the time it takes for the camera to project the light source to the measurement point and return to the camera, H 0 Measuring point height threshold when H > H 0 At the moment, the output of H is 0, which indicates that the position is not suitable for the construction of the transformer substation, and when H is less than or equal to H 0 And the output H is 1, which indicates that the position is suitable for the construction of a transformer substation.
