Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
At present, a commercially available petroleum logging information transmission system designed based on the principle of the internet of things mostly takes a CAN protocol and a TCP/IP protocol as technical bases, meanwhile, the underground transmission and the ground transmission are realized by optical fiber communication, and in addition, a wireless network architecture is additionally arranged on the ground. However, the scheme is only applied to well sites which are relatively concentrated or have good network coverage conditions, and is greatly influenced by terrain, and the antennas of the master/slave stations in the wireless network components in the equipment structure are visible to each other and are greatly influenced by terrain factors. The 4G network is greatly affected by the operator signal coverage area and the base station capacity. Especially, it is very costly to build a wireless private network at the well site in the marginal zone or lay the optical cable. Even through the comprehensive consideration of geographic position and terrain, the remote transmission communication of the approach data cannot be realized. The technical problem that an industrial field Internet of things data transmission system cannot cover communication transmission for remote areas at the extreme end and areas with extremely severe geographic conditions in the prior art is solved.
