In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to embodiments, to the present invention
It is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to
Limit the present invention.
The application principle of the present invention is explained in detail below in conjunction with the accompanying drawings.
The present invention as shown in Figure 1 is used to detect the structure chart of the positioning device of underground piping combustible gas leakage, mainly
Including gas sensor 4, UWB positioning label 1, UWB locating base stations 2 and positioning service engine 3;The gas sensor 4 is used
In the leakage of detection gas, the input terminal that signal output end positions label 1 with the UWB is connected, UWB positioning marks
Label 1 are communicated by UWB signal to be connected with the UWB locating base stations 2, and the UWB locating base stations 2 are by received data
Carry out being analyzed to identify the location of the pipeline that gas leakage occurs in the positioning service engine 3 by being wirelessly transmitted to.
Wherein, if the surface interval of gas pipeline in the signal cover of the UWB locating base stations 2 is attached to
The dry gas sensor 4 and coupled UWB position label 1.Base is positioned when UWB positioning labels 1 enter UWB
It stands in 2 signal cover, passes through the transmission and response of position matching stage " Blink-Response " message, you can is automatic
It communicates with locating base station foundation, can then be positioned.Simultaneously because the UWB positioning marks described in each on gas pipeline
The ID number of label 1 is all unique, the accurate location for marking gas pipeline, so entire underground gas pipeline is all visual
's.
The present invention is positioned by detecting distance of the UWB positioning labels 1 apart from the UWB locating base stations 2, for
It is identical as the distance between the same UWB locating base stations 2 there may be two UWB positioning labels 1 in same coverage, because
This is provided with the UWB locating base stations 2 described at least two in same service area.The UWB locating base stations 2 include suspension type
With two kinds of forms of adhesive type, the present invention is arranged using suspension type, the UWB locating base stations 2 apart from ground surface 2-
The underground of 2.5m is distributed in the edge of underground piping side, by arbitrary in rectangle, linear type, triangle or scattered type
One kind being arranged installation, to ensure the distance values of any one UWB positioning labels 1 and all UWB locating base stations 2 only
One property.The spacing between UWB locating base stations 2 described in two is 8-20m, preferably 10m.
The information that the UWB locating base stations 2 receive includes the sending time and UWB positioning bases of UWB positioning 1 data of label
The time information data packet is sent to positioning service engine 3 and carried out by the time for 2 reception data of standing, the UWB locating base stations 2
Analysis.The positioning service engine 3 calculates UWB according to the sending time of data and the time difference of receiving time and positions label
The distance between 1 and each UWB locating base stations 2, to judge that UWB positions the ID number completion positioning of label 1.
Further include wireless synchronous control device 5, the wireless synchronous control device 5 is connected with the UWB locating base stations 2,
