Problems solved by technology
[0003] Infrared positioning technology can only be used for short-distance transmission, and is easily interfered by other light, so it has certain limitations in positioning accuracy
Although GPS positioning technology has been widely used and covers a wide range, the GPS signal to the ground is very weak and cannot penetrate the ground buildings well, so in most cases it is limited to outdoor positioning
The cost of Wi-Fi positioning technology is relatively low, but whether it is outdoors or indoors, the signal coverage radius is very limited, and it will cause interference to other signals, resulting in data distortion of other signals

The invention discloses a pipe-rack inspecting positioning system based on the radio frequency identification technology. The pipe-rack inspecting positioning system comprises a pipe-rack robot, a reader-writer part and electronic tags; the electronic tags are sequentially arranged along the inner wall of the a pipe rack, position coordinates of a pipe rack are correspondingly recorded by all theelectronic tags, and the reader-writer part for identifying the electronic tags is arranged on the pipe-rack robot. The pipe-rack inspecting positioning system based on the radio frequency identification technology has the advantages of being high in positioning accuracy, low in environmental requirement and high in economy.
Description
technical field [0001] The invention relates to the field of pipe gallery monitoring, in particular to a pipe gallery inspection and positioning system based on radio frequency identification technology. Background technique [0002] The pipe gallery is built underground, the environment is complex, and the lighting conditions are very insufficient. Therefore, it is necessary to adopt a certain method to determine the current position of the pipe gallery robot in real time. Traditional positioning technologies include infrared positioning technology, GPS positioning technology and Wi-Fi positioning technology. [0003] Infrared positioning technology can only be used for short-distance transmission and is easily interfered by other light, so it has certain limitations in positioning accuracy. Although GPS positioning technology has been widely used and covers a wide range, the GPS signal to the ground is very weak and cannot penetrate ground buildings well, so in most cases...
