In an optional application scenario, taking a tunnel as an example, two fixed coordinate base stations (i.e., the at least two first positioning base stations) are installed at an entrance of the tunnel, and the two fixed coordinate base stations are sequentially arranged along an extending direction of the tunnel, and are used for positioning a constructor (i.e., the target node) within a communication range covered by the two fixed coordinate base stations, wherein the constructor is worn with a positioning tag, the positioning tag is provided with a positioning module and a power supply module, the base stations transmit positioning information to a server, and the server calculates a position of the constructor (i.e., the first position information), so that one-dimensional positioning of the constructor at the entrance of the tunnel is realized.
In another optional embodiment of the present disclosure, the at least two second positioning base stations are fixedly disposed on the first mobile device, a connection line of at least two of the at least two second positioning base stations is perpendicular to an extending direction of the elongated space, and the first mobile device is located at a target operation plane of the elongated space, and the obtaining the first position information of the target node through data communication includes: acquiring third position information of a first preset reference tag in a long and narrow space and second positioning information for positioning a target node through at least two second positioning base stations, wherein the first preset reference tag comprises a positioning module, a coplanar waveguide antenna is arranged in the positioning module, and the first preset reference tag can communicate with the at least two second positioning base stations; calculating at least two fourth position information of at least two second positioning base stations according to the third position information; and calculating first position information of the target node according to the at least two fourth position information and the second positioning information.
In another optional application scenario, taking the tunnel as an example, a trolley (i.e., the first moving device) is disposed at a tunnel face (i.e., the target working face) of the tunnel, such as a tunneling trolley, a waterproof trolley, and the like, the trolley moves along with tunneling of the tunnel face, the trolley is provided with two base stations (i.e., the at least two second base stations), a connection line of the two base stations is perpendicular to an extending direction of the tunnel, and a reference tag (i.e., the first preset tag) is disposed between an entrance of the tunnel and the tunnel face, and the reference tag includes a positioning module and a power supply module. In this embodiment, the reference tag and the two base stations on the trolley can communicate with each other, the two base stations on the trolley are located through the reference tag, the location information is sent to the server, and the server calculates the position coordinates of the two base stations on the trolley, so that one-dimensional location of constructors around the trolley is achieved according to the two base stations on the trolley.
In an exemplary scenario, as shown in fig. 2, fig. 2 is a top view of a first layout manner of base stations in a tunnel according to an embodiment of the present invention, two fixed coordinate base stations B1 and B2 (i.e. the at least two first positioning base stations) are installed at a tunnel entrance, and a reference tag T1 (i.e. the first preset tag) is placed at a distance to the right side of the fixed base stations in the horizontal direction (the distance depends on the distance range in which the base stations and the tag can communicate). Two base stations B3, B4 (i.e. the above-mentioned at least two second positioning base stations) are installed on the trolley, wherein the connecting line of B3 and B4 is perpendicular to the extending direction of the tunnel.
Preferably, the one-dimensional positioning of the constructor in the tunnel comprises a plurality of ways.
In a first mode
During the early stage of tunneling, the reference tag T1 can communicate with B1 and B2, and after the scheme is deployed, the program starts to receive the network data of the base station, it is possible to receive ranging data (ranging data in which the distance between the base station and the communicable tag is given) from the base station, calculate the position of the reference tag T1 (i.e., the above-mentioned third position information) using the ranging information of T1 and B1, T1 and B2, select an origin based on the line connecting B1 and B2 as the X-coordinate axis, taking the vertical direction of the connecting line of the B1 and the B2 as the Y coordinate axis, a coordinate system is established, such as the schematic diagram of the coordinate system shown in fig. 2 (the coordinates obtained in the embodiment are relative to the origin O of coordinates in fig. 2), alternatively, the coordinates of the B1, B2 and the reference T1 label on the Y axis are made equal and kept constant, and their positional relationship in the coordinate system can be obtained from distance measurement.
Assuming that B1 coordinates are (B1x, B1y), the distance between T1 and B1 is B1 range finding, B2 coordinates are (B2x, B2y), and the distance between T1 and B2 is B2 range finding, T1 (T1x, T1y) is calculated by the following formula:
t1x ═ ((B1x + B1 rangefinder) + (B2x + B2 rangefinder))/2;
T1y＝B1y＝B2y；
further, using ranging information of B3, B4, and T1, wherein B4 ranging represents a horizontal distance of B4 to T1, by the following formula:
b4x ═ T1x + B4 ranging;
B4y＝T1y；
B3x＝B4x；
b3y ═ B4y + fixed distance L;
wherein, the y-axis distance between the base stations B3 and B4 is known as a fixed distance L.
Further, the exact coordinates of base stations B3, B4 are calculated, and then the coordinates of base stations B3, B4 are updated, so that one-dimensional positioning is performed on the tags T2, T3, … Tn (i.e., the constructors) on the right side of the trolley.
Preferably, in order to make the calculated value more accurate, the algorithm scheme is adopted as follows: after B1 and T1, B2 and T1 distance measurement data are collected for a certain threshold number of times (the distance measurement times are configurable, for example, default 10 times), a mode of removing the maximum value and the minimum value distance measurement is adopted, then the remaining distance measurement data are averaged and used as the final distance measurement data of B1 and T1, and B2 and T1 to calculate the coordinate of the reference label T1. Since the relative positions of the T1, the B3 and the B4 are fixed, the coordinates of the B3 and the B4 can be more accurate by acquiring the accurate T1 coordinate, and further the position coordinate of the constructor can be more accurate.
Mode two
According to the application scenario, during tunneling, the reference tag T1 moves away from B1 and B2 along the tunneling direction, and T1 cannot communicate with B1 and B2 for ranging.
When the trolley moves forwards along with the heading of the tunnel face, if the distance between the reference tag T1 and the base stations B3 and B4 on the trolley exceeds the distance which can be communicated with the tag by the base stations, the reference tag T1 is moved to the right to reach the distance which can be communicated with the base stations B3 and B4; further, the reference label T1 may be used to measure the precise coordinates of the reference label every time it is moved in the tunneling direction using a laser rangefinder and update the coordinates of the reference label T1 in the positioning system.
In this embodiment, obtaining the coordinates of the reference tag includes the following two cases:
1a) if the absolute coordinates of tags T2, T3, … Tn are not of interest in the tunnel, and only the relative location of the tags on the right side of the cart is of interest, reference tag T1 may be provided with a fixed coordinate (i.e., the third location information described above), with the location of tags T2, T3, … Tn being located relative to reference tag T1.
2b) If the absolute coordinates of the tags T2, T3, … Tn in the tunnel are of interest, the coordinates of T1 (i.e., the third positional information described above) can be measured using a laser rangefinder.
Further, the coordinates of the base stations B3 and B4 are updated according to the scheme of calculating the coordinates of B3 and B4 (i.e., the fourth position information) according to the reference tag T1 in the first mode.
In a preferred embodiment, the specific process of positioning is implemented by actively transmitting a pulse signal by the tag to perform ranging communication with the base station, for example: the flight time of the electromagnetic wave between the tag (such as the tag carrying the module of the target node) and the base station (the positioning base station) is T2-T1 (where T1 is the time of sending the pulsed electric wave, and T2 is the time of receiving the pulsed electric wave); the distance D between the two points is C (speed of light) × (T2-T1) (time of flight of electromagnetic waves), thus realizing one-dimensional positioning of the target node.
Preferably, if two base stations are additionally arranged on a trolley (such as a tunneling trolley) and the connecting line of the two newly arranged base stations is also perpendicular to the extending direction of the tunnel, two-dimensional positioning can be performed on constructors around the trolley according to 4 base stations on the trolley; if the trolley is additionally arranged on the tunnel face (a plurality of positioning base stations are arranged on the trolley), two-dimensional positioning can be carried out on constructors between the two trolleys. But is not limited thereto.
In another application scenario of the present disclosure, fig. 3 is a top view of a second base station layout in a tunnel according to an embodiment of the present disclosure, as shown in fig. 3, two fixed coordinate base stations B1 and B2 (i.e. the at least two first positioning base stations) are installed at a tunnel portal, a reference tag T1 (i.e. the first preset tag) is placed at a certain distance from the right side of the fixed base station in the horizontal direction (the distance depends on the distance range in which the base station and the tag can communicate), 3 trolleys are installed in front of a tunnel, two trolleys are sequentially a village trolley, a waterproof trolley and a tunneling trolley, wherein the base stations B3 and B4 are installed on the two trolleys, a connection line of the base stations B3 and B4 is perpendicular to the tunnel extending direction, constructors T2 and T3 … … are installed between the village trolley and the waterproof trolley, and the base stations B5, B6, B7, and T3 … … are installed on two, The connecting lines of B8, B5 and B6 and the connecting lines of B7 and B8 are all perpendicular to the extending direction of the tunnel, constructors T5, T6, … and Tn between the waterproof trolley and the tunneling trolley are provided with base stations B9 and B10, and the like. Furthermore, the distance between B3 and B4, the distance between B5 and B6, the distance between B7 and B8, and the distance between B9 and B10 are known.
The two-dimensional positioning of the target node is realized by the following steps:
1) in the early stage of tunneling, T1 can measure distance with B1 and B2
After the scheme is deployed, the program starts to receive network data of the base station, and can receive ranging data (the ranging data gives the distance between the base station and the communicable tag) sent by the base station, and the ranging information of T1 and B1 and T1 and B2 is obtained through the following formula:
t1x ═ ((B1x + B1 rangefinder) + (B2x + B2 rangefinder))/2;
T1y＝B1y＝B2y；
the exact coordinates of tag T1 can be calculated.
Further, using the ranging information of B3 to B10 and T1, the algorithm in the above-mentioned manner one is used to calculate the accurate coordinates of base stations B3 to B10, and then to update the coordinates of base stations B3 to B10. At this time, the wireless positioning system in this embodiment can perform two-dimensional positioning on the two-lining trolley and the waterproof trolley, and constructors T2, T3, and … Tn between the waterproof trolley and the heading trolley.
2) In the tunneling process, T1 cannot measure distance with B1 and B2
When the trolley is advancing in the positive direction of the X axis (namely the extending direction of the tunnel), if the distance between the reference tag T1 and the base stations B9 and B10 on the tunneling trolley exceeds the distance that the base stations can communicate with the reference tag, the reference tag T1 is moved to the right by a certain distance, so that the reference tag T1 can communicate with the base stations B9 and B10.
In this embodiment, obtaining the position coordinates of the reference tag includes the following two cases:
1a) if the absolute coordinates of the tags T2, T3, and … Tn in the tunnel are not concerned, only the relative positions of the tags between the trolleys are concerned, a fixed coordinate (i.e. the third position information) is set for the reference tag T1, the positions of the located tags T2, T3, and … Tn are the coordinates relative to the reference tag T1, the subsequent procedure is the same as the previous one, and the coordinates of the base stations B3 to B10 are automatically updated, which is not described herein again in this embodiment.
2a) If the absolute coordinates of the tags T2, T3, and … Tn in the tunnel are concerned, the coordinates of T1 (i.e. the third location information) can be tested by using a laser range finder, and then the coordinates of the base stations B3 to B10 are automatically updated by the following process as before, which is not described herein again.
In both cases, the coordinate position set by the reference tag T1 needs to ensure that T1 can communicate with the base stations B3 to B10, so as to realize two-dimensional positioning of the target node through at least 3 positioning base stations (the 3 positioning base stations are not collinear on the horizontal plane).
Optionally, the reference tag T1 provided in the embodiment of the present invention includes a coplanar waveguide antenna, and has good signal transceiving performance in the X-axis direction (i.e., the tunneling direction) during tunnel positioning, and low signal sensitivity in the Y-axis direction, so that reflection interference generated by a positioning signal passing through a tunnel wall can be effectively reduced, thereby ensuring the accuracy of distance measurement between T1 and B1, B2. Specifically, in the tunneling process, the reference label T1 moves rightward along the X axis and is equal to the coordinates of B1 and B2 on the Y axis, so that the position of the reference standard T1 relative to B1 and B2 can be updated through ranging, and the positioning accuracy and the attendance accuracy of the target are improved.
In an optional embodiment of the present disclosure, the at least two third positioning base stations are fixedly disposed on the second mobile device, a connection line of at least two of the at least two third positioning base stations is perpendicular to an extending direction of the elongated space, the second mobile device is located between the first preset reference tag and the first mobile device, and the second mobile device is further provided with a second preset reference tag, and after calculating at least two fourth position information of the at least two second positioning base stations according to the third position information, the method further includes: calculating at least two fifth position information of at least two third positioning base stations according to the third position information; calculating sixth position information of a second preset reference label according to the at least two fifth position information, wherein the second preset reference label comprises a positioning module, and a coplanar waveguide antenna is arranged in the positioning module; calculating at least two pieces of seventh position information of the at least two first positioning base stations according to the sixth position information; and updating at least two fourth position information according to the at least two seventh position information.
According to the above embodiment, as shown in fig. 3, since the distance from the reference tag T1 to the bs B5 to B10 is a little longer, in order to make the coordinate update of the bs B5 to B10 more accurate, a verification algorithm scheme is adopted: a calibration tag Ta (i.e., the second preset reference tag) is placed at a fixed position on the second carriage (i.e., the second mobile device), the coordinates of Ta are fixed with respect to the base stations B3 and B4, and the coordinates of the calibration tag Ta (i.e., the sixth position information) are calculated by the base stations B3 and B4. Then, according to the method of updating the coordinates of the base stations B3 to B10 by using the reference label T1, the coordinates of the base stations B5 to B8 are updated by using the calibration label Ta, namely, the relay is arranged between the reference label and the mobile equipment, so that the positioning precision of the target node is improved, and the entering and exiting conditions of constructors in the tunnel are accurately obtained.
Preferably, calibration tags Tb are placed at the waterproof trolley fixing positions, the logic of base stations B5 to B8 is calibrated according to Ta, and Tb is used for calibrating the coordinates of base stations B9 to B10 to achieve higher precision, and the accuracy of the coordinates of base stations B9 to B10 is further improved.
