Problems solved by technology

At present, the indoor communication system and the indoor positioning and navigation system are two independent networks, which greatly increases the complexity and space pressure of indoor wiring, and increases the construction cost
Although GPS or Beidou signals or RFID signals have been added to both ends of the leaky cable in the tunnel scene to achieve positioning in the tunnel, the positioning accuracy is not high due to the positioning system design and bandwidth constraints of GPS, Beidou and RFID

Embodiment 1

[0058] Embodiment 1, the location carrier is a Bluetooth beacon, which has its own unique location information, the location carrier includes a location carrier body and a power cord, and the power cord is directly electrically connected to the location carrier body to realize power supply operation. The position carrier is arranged between the conductor and the jacket (it can also be arranged in the jacket, such as heating with a heat shrink tube so that the position carrier is integrated in the jacket). In this embodiment, the acquisition process of the first positioning signal is that the terminal sends information, which is transmitted to the combiner / splitter through the leakage unit, and the combiner / splitter transmits it to the first positioning base station in response to the feedback information, and the combiner / splitter transmits the information from the combiner / splitter. The input is transmitted and interacted with the terminal through the leakage unit, and the ter...

Embodiment 2

[0059] Embodiment 2, the location carrier is a Bluetooth beacon, which has its own unique location information, the location carrier includes a location carrier body and a power cord, and the power cord is electrically connected to the location carrier body to achieve power supply operation. The power cord is integrated between the conductor and the sheath (it can also be integrated in the sheath, for example, the position carrier is integrated in the sheath by heating with a heat-shrinkable tube), and the position carrier body is installed outside the sheath or on the sheath, the power supply The wire is provided with an exposed connector socket, which is engaged and connected with the connector of the position carrier body. The position carrier body can be fixed on the sheath by, but not limited to, ferrule, sticking, or sticking. In this embodiment, the acquisition process of the first positioning signal is that the terminal sends information, which is transmitted to the com...

Embodiment 3

[0060] Embodiment 3, the location carrier is a Bluetooth beacon, which has its own unique location information, the location carrier includes a location carrier body and a battery built in the location carrier body, and the battery supplies power to the location carrier body. The position carrier is installed on the sheath, so that the built-in battery can be replaced regularly, such as installing by way of card sleeve, sticking, sticking, etc. In this embodiment, the acquisition process of the first positioning signal is that the terminal sends information, which is transmitted to the combiner / splitter through the leakage unit, and the combiner / splitter transmits it to the first positioning base station in response to the feedback information, and the combiner / splitter transmits the information from the combiner / splitter. The input is transmitted and interacted with the terminal through the leakage unit, and the terminal performs calculation; the acquisition process of the sec...

Abstract

An indoor communication and conduction integrated network provided by the present invention includes a communication signal source, a first positioning base station, a combiner / splitter and a leakage unit. The communication signal source and the first positioning base station pass through the combiner / splitter. The router is connected to the input end of the leakage unit, the communication signal is transmitted through the leakage unit and indoor coverage to realize the information exchange between the terminal and the communication server, and the first positioning signal is based on the position of the terminal and the first positioning base station The relative position calculated from the interaction information is obtained, and the terminal performs navigation and positioning based on the first positioning signal. The invention provides an integrated network with both communication and navigation and positioning functions applied indoors, without re-arranging an indoor positioning network, reducing the space pressure of the indoor wiring network, effectively reducing the cost of indoor construction, and having higher positioning precision.

Description

technical field [0001] The invention relates to the technical field of indoor positioning, in particular to an indoor communication and conduction integrated network. Background technique [0002] With the development of a highly information-based society, the number of online users has doubled every year, and there are more and more network hotspots. However, indoor environments such as densely populated high-rise offices, general residential houses, and large shopping malls have more and more requirements for wireless signal coverage. higher. The traditional indoor distribution system is the antenna + feeder method, which has the problems of signal blind area, large electromagnetic pollution and inability to install concealed. The characteristics of leaky cables, such as uniform coverage, no signal dead angle and concealed installation, have attracted more and more attention and are more and more widely used. At the same time, with the construction of urbanization, more ...
