[0027] Specific implementation method
[0028] In order to make the content and advantages of the technical solution of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0029] figure 1 It is a block diagram of the positioning method system of the present invention, including a ground monitoring system (1), a positioning computer (2), an optical fiber (3), a switch (4), a bus (5), a gateway (6), and a reference node (7) , target node (8). All the downhole equipment involved are intrinsically safe equipment, wherein the target node (8) is carried by downhole personnel or equipment.
[0030] like figure 1 As shown, the downhole positioning method based on the compressed sensing RSS fingerprint library and ultrasonic waves described in the present invention is as follows: the reference node (7) is arranged on both sides of the downhole roadway wall, receives the signal strength and...
